The IMPLEMENTATION of the INVENTION

On Figa shows the electrical connecting device 16, which in the invention is sometimes referred to as terminals or switching unit. The connecting device 16 has a generally rectangular construction. For example, in alternative embodiments of the invention the connecting device 16 may have a structure in the form of a rectangular parallelepiped box-like structure with sides of tubular or rectangular shape or design in the form of a straight cylinder. The connecting device 16 has a base 21 and a number of plugs or caps 18, placed on its upper and lower sides. In particular, Figa shows a number of lids 18, placed on the top side of the base 21, the lid 18 is in the open position, and the cover 18B is closed. Not shown, but the cover 18 can be placed on the bottom side of the base 21. In an alternative example embodiment of the invention the underside of the base 21 may have a number of covers of different designs, as it is explained in details below.

As shown In figure 1, the cover 18 may be pivotally connected with the base 21, for example the EP, through a series of pins or swivel axis 19 included in engagement with the respective legs 17 of the rotary axes, made in the base 21. In the preferred embodiment of the invention by means of a hinge mechanism of the cover can be rotated in the range of 90° or more. In accordance with embodiments of the invention and as described in detail below, by means of a cover 18 can simply install electrical wiring for connection to the connecting device, since the first wire is installed in the cover 18, placing it in a comfortable position or at a comfortable angle. In particular, this design provides simplified installation in high-density equipment, when the connecting devices are very close to each other.

On FIGU presents a cross-section of the connecting device 16, is received along line 2B-2B shown in Figa, you can see that the base 21 has a number of contacts 30. The contacts 30 are used for the electrical connection of the first row of wires 23 and the second row of wires 63 (shown in Figa). Usually the wires 23, 63 may be twisted wire pairs, referred to in the field of telephony "Tip" and "Ring". As the wires you can use any standard telephone wire with PVC insulation (or other conventional insulation). So the mi cables can be but not limited to: wire with a diameter corresponding to 22 AWG (American Wire Gauge wire gauge) (round copper conductor with a nominal diameter of 0.025 inch (0.65 mm) with a nominal thickness of PVC insulation 0.010 inch (0.25 mm)); wire diameter corresponding to 24 AWG (round copper conductor with a nominal diameter of 0.020 inch (0.5 mm) with a nominal thickness of PVC insulation 0.010 inch (0.25 mm)); wire diameter corresponding to 26 AWG (round copper conductor with a nominal diameter to 0.016 inches (0.4 to mm) with a nominal thickness of PVC insulation 0,010 inch (0.25 mm)). Despite the fact that the described embodiments of the invention are especially characteristic of the coupling devices designed for switching twisted pairs, to a person skilled in the art it is obvious that the connecting device can be used for connecting single wires or series of single wires, also using the cover for a single wire or a number of such covers (shown on Fig). Additionally, according to another alternative embodiment of the invention, such a cover can be performed with the possibility of placing it and connect one or more wires(1, 2, 3, 4, 5 or more) with one or more insulation displacement contacts of the connecting device, printed circuit Board or other electrical or telecommunications mustache the device (examples are shown Figa and Fig). The base 21 preferably of dielectric thermoplastic filler with fiberglass. For example, the base 21 may be made of structural plastic, such as, but not limited to, Valox® 325 - polymeric compound polybutylene terephthalate, supplied by GE Plastics, located in getzville, Massachusetts; Lexan® 500R - fire-resistant polycarbonate resin with 10% glass fiber, supplied by GE Plastics, located in getzville, Massachusetts; Makrolon® 9415 fire-resistant polycarbonate resin with 10% glass fiber, supplied by Bayer Plastics Division, located in Gettysburg, Pennsylvania, or Makrolon® 9425 - fire-resistant polycarbonate resin with 20% glass fibre, supplied by Bayer Plastics Division, located in Gettysburg, Pennsylvania.

On the top or bottom surfaces of the base 21 in General made several sections (for example, section 20 shown in Figv). For example, as shown in Figa, the base 21 has 10 pairs of sections (top and bottom). Also in the base 21 made a number of rows of sockets 25 for placing the contacts 30 (shown In figure 2). The above-mentioned materials, which can be used for the manufacture of the base, provides excellent insulation of the contacts 30 in the slots 25 and sufficient strength is voyta, necessary to connect the wires with the contacts 30. Sections are structural elements, designed to prevent warping or deformation of the base during molding of thermoplastic. Both upper and lower sides of the base 21 are pins 22 and 24, and the groove located between the pins 22 and 24, contributes to the alignment of the first row of wires 23 and the second the number of wires 63 held by the lid 18. The size of the groove between the pins 22 and 24 may be slightly larger outer diameter wires.

On Figa shows the design of the contact 30, preferably mortise contact (also mean in the invention mortise element 30). On FIGU shows the contacts 30 mounted in the base 21. A contact can be placed in the contact section 20 (shown in Figv) of the connecting device 16. The contact section can also be filled with a sealant, such as conventional gel to prevent the ingress of humidity and corrosion of the contact.

As sealants for this purpose can be used in synthetic lubricants and gels, such as, but not limited to, RTV® 6186, mixed in the ratio a/b from 1.00 to 0.95, manufactured by GE Silicones, located in goatherd, new York. The gels, which can be described as a sealing material containing a three-dimensional CE is ku, are limited by the properties of the limit of elasticity that allows them to maintain contact with structural elements for which such gels are designed. Can be used gels having a chemical composition that includes one or more of the following elements: (1) plasticized thermoplastic elastomers, such as resistant to swelling in oils triple the Kraton polymer; (2) cross-linked silicones, including diluted silicone oil and a polymer obtained by cross-linking reactions, such as vinylsilane, and possibly other modified siloxane polymers, such as silanes or nitrogen, halogen, or sulfur derivatives; (3) resistant to swelling in oils crosslinked polyurethane or urea, is usually obtained from isocyanates and alcohols or amines; (4) resistant to swelling in oils, polyesters, usually derived from the acid anhydride and alcohols. You can also use other gels. If necessary to provide additional functionality in the gel can be added other components, such as anticoagulants, antioxidants, ultraviolet absorbers, colorants, etc. Used gels can have a value of penetration in the range from 15 to 40 units, obtained using a steel ball with a diameter of 0.25 inch and the speed component of 2 mm/sec on lupine 4 mm in the sample, contained in the Cup, such as described in the test ASTM D217 American society for testing and materials (cylinder 3 inches in diameter and 2.5 inches in height, filled to the brim). Additionally, the limit of elasticity in accordance with tests ASTM D412 and D638 may be at least 150% and more preferably at least 350%. Such materials may have an adhesive strength of which exceeds the adhesive strength of the surface of the gel or the like.

Typical compositions are gels obtained from 3-15 parts Kraton® G 1652 - block copolymer of styrene-ethylene-butylene-styrene (SEBS) manufactured by the company Kraton Polymers, LLC, located in Houston, Texas, and 90 parts of petroleum oil, optionally with antioxidants to slow decomposition when mixing and distribution.

Mortise contact 30 may be made of electrically conductive metal material. In one embodiment of the invention mortise contact 30 may be made of phosphor-bronze brand S according to the standard ASTM 103/M-e, tin-tin method reflow thickness 0,000150-0,000300 inch according to ASTM F-97(2004)E2, and the galvanised Nickel sublayer thickness minimum 0,000050 inch according to SAE-AMS-QQ-N-290 (Jul 2000).

Mortise contact 30 may have two ends of the essentially U-shaped is army. For example (see Figa), and the first end 91 and a second end 92 have made them in the slot 93 U-shaped. The slots 93 a U-shape is arranged to engage respectively the first row of wires 23 and the second row of wires 63. The ends of the U-shaped design which allows for the establishment wires in them to penetrate the wire insulation to provide a connection with the conductors of the wires.

As shown in Figv, mortise contacts 30 can be installed in the slots 25 of the base 21. In the preferred example of the invention, the open ends of the essentially U-shaped slots 93 mortise contacts 30 may be beveled or rounded. Preferably, the width of the slots 25 is selected approximately equal to or slightly greater than the thickness of insulation displacement contacts 30 to mortise the contacts 30 held, and not loosened or turned in the base 21. In addition, contacts for areas where electrical connection can have spikes 301, 302 with a solution greater than that of the slots 25, 25 nests made cavity for placement of studs 301, 302. When cutting the pins 30 wound in the slots 25 at the set depth, the studs 301, 302 are released from the narrow slots 25 and are fixed in locations. Pinning so mortise contacts 30 into the slots 25 excludes vertical offset is tion.

Additionally in detail in figure 4 and Fig shows the different types of sample cover 18. Cover 18 is arranged to cover the contact section of the connecting device. The cover 18 is provided to connect one of a number of wires, such as wires 63, with another adjacent wire by insulation displacement contact simple closing the lid 18. Thus, when the wire is secured in the mortise contact 30, the pivoting of the cover 18 does not disconnect the attached wires from the insulation displacement contact or not divides them. In addition, the cover 18 has samozaschelkivayuschiysya and razlichimy lock, which can be manually actuated and which can withstand repeated cycles of closing and opening. The cover 18 also has the range to test, designed to test the contacts, and the zone of visual inspection to verify the location of the wires. While figure 4-12 shows examples of a cover 18 made as a separate design, from the description to a person skilled in the art it is obvious that you can perform as one of a large number of lids 18 (for example, to open and close at the same time).

In the example of the invention, the cover 18 has a main part 101, section 102, the retaining wire, and the latch 120. If desired, the cover 18 may additionally be C the well access 140 for testing and an area of 150 visual inspection. The main part 101, which may be made of insulating material, has a General rectangular shape, allowing to cover the contact section with insulation displacement contacts of the connecting device 16. The cover 18 can be made of structural plastic, such as, but not limited to, Ultem® 1100, supplied by GE Plastics, located in getzville, Massachusetts; Valox® 420 SEO - fire-resistant polycarbonate resin with 20% glass fiber, supplied by GE Plastics, located in getzville, Massachusetts; IXEF® 1501 - fire-resistant polycarbonate resin with 20% glass fiber, supplied by Solvay Advanced Polymers, LLC, located in Gallarate, state of Georgia, or IXEF® 1521 - fire-resistant polycarbonate resin with 20% glass fiber, supplied by Solvay Advanced Polymers, LLC, located in Gallarate, the state of Georgia. In the preferred embodiment of the invention as a material for the manufacture of the cover 18 can be used flexible plastic material, such as Makralon® 2658, 2850, 2407 or 2607 - polycarbonate resin, supplied by Bayer Plastics Division, located in Gettysburg, Pennsylvania. In one embodiment of the invention the material used for the manufacture of the cover 18 may be essentially transparent. In another embodiment, the image is etenia material, used for the manufacture of the cover 18 may be translucent.

Each cover 18 has a holding wire section 102 depicted in Figa as holders 102A and 102 In the wires. Holders 102A and 102 In wires have a generally cylindrical or tubular shape, wherein each holder has a hole 103, the size configured to accommodate the wires and create a support wire, such as described above. As shown, the holders of the wires are preferably placed underneath the top surface of the cover and positioned opposite mortise contacts placed in the base 21. Holders 102A and 102 b may be the same or different. For example, the hole in the bracket 102 can be performed so that it may be different (for example, to have a different shape, different color etc) from the holder opening 102A to indicate that a particular wire you need to make in the holder 102, and not in the holder 102A.

When mounting the wire 63 can get through the holes 103 until the end of the wire will not touch the rear wall 114 of the cover 18 (shown in Fig.6 and also on the form in section, shown in Figure 10). The cover 18 also has a cut-out or cross-sample 110, which is made with mortise placement of the contact 30 when the cover is in the closed position, so that when the lid is served basis 21, pop the river sample 110 is in the correct position relative to the insulation displacement contact 30 and the socket 25. The width of the sample 110 is slightly greater than the thickness of the mortise contact 30. The cover 18 can be opened and closed repeatedly without touching directly mortise contact 30.

As shown in Figv, which depicts the bottom side of the cap 18, the transverse sample 110 may be placed within the boundaries of the first and second protrusions 107, performed on the bottom surface 105 of the cover. The protrusions 107 may interact with the set of wires so that the wires went into the slot mortise contacts when the cover is closed. The cover 18 may also have guide sections 109, which define transverse wires when installing them until it touches the back wall 114 and during the connection.

In an alternative example embodiment of the invention, as shown in Fig.4D, cover 18 may have a rear wall 114', performed with gradually deepening or arcuate recess. The arcuate shape of the rear wall ensures that the end of the wire is not meshed with the rear wall and therefore not coming out of his cut-in contact, when the lid 18 is opened and closed during numerous operations.

In addition, both the holder 102A, 102 IN wires have longitudinal slot or gap 104 that allows you to move and securely fastened in flush contact 30 wire, placed in the area to hold the air traffic management (shown in Figure 10-12). In addition, holders 102A and B have sufficient flexibility such that when the cover is again tilted (see Fig), wire 63 may remain inside the mortise contact due to the fact that the clamping pressure is essentially U-shaped slots 93 mortise contact more power clamp holders 102A, V wires. As described below, until the top is folded, the wire 63 is held essentially U-shaped slot 93 as a longitudinal slot or gap 104 is open to the wire 63 could stay inside mortise contact.

For example, as shown in Figs, in an alternative example embodiment of the invention, each of the holders 102A, 102 IN wires may additionally have respective through-slots A and 104 made in the main body 101 of the cover and located essentially opposite the slots 104. Such additional end-to-end slits A and B allow the legs of the holders of wires, for example the legs of V' and V" to bend independently of each other.

In addition, each side of the slit conductor holder can optionally have a widening in the direction from the slot 104 of the end sections 106. If any such extending end sections easier to close the lid 18 when the wire is fixed in a substantially U-shaped slot 93 mortise contact 30, he is not shifted or out of cutting contact 30 (respectively produced by the manipulation of the e effect on the electrical connection).

As mentioned, the cover 18 also has a latch 120. In the preferred embodiment of the invention the latch 120 is a cast, made in one piece of the cover 18. As shown in a perspective view on Figa and 6, the cover is made in the form of elastic lystopadovogo element 124 having a gripping surface. At the same time its exciting surface can be performed ledges or exciting pads 122. As shown in Fig, figures 9 and 11, spectacular legs 122 is configured to engage the protrusion, such as a T-shaped pin 27, is made in the base 21, to hold the cover 18 in the closed position. The protrusion or pin 27 may be rigid or elastic. The pin 27 can also be different from the T-shaped form, with a specific form should be performed to make the locking latch and the lid was closed, while the specialist will not open deliberately.

In one embodiment of the invention, the pin 27 is made in the form of an elastic cantilever rod, which has protrusions 27A and 27B for coupling with respective exciting pads 122, so that the cover is accidentally opened. In one embodiment of the invention the outer edges of the protrusions 27A and 27B can be beveled. In a preferred embodiment, izaberete the Oia element 124 has sufficient flexibility in order for you to reject or to bend in any direction along the line 126, shown in Figure 5 and 7. Movement forward and back can be very small (for example, from 0.01 to 0.02 inch) and still provide sufficient air movement. For example, when the cover 18 is lowered, moving to the closed position, the element 124 of the latch can be moved inward to allow the T-shaped pin 27 to go around the element 124. In the preferred embodiment, of the invention can hear the sound of the lock clicks when the tabs 122 of the latch engages with the T-shaped pin 27. Unlocking can be performed by simply pressing a thumb or other finger on the key 123. So, when you press the 123 foot latch to be released from the T-shaped pin 27 and fold the cover 18.

The latch 120 includes a travel stop, such as the locking tabs 128, performed on the upper surface of the cover 18, which may limit the offset of the element 124 on the sides. The possibility of replacing the lock inward (toward the rear wall 14) is provided with a hole 127 in the top surface of the cover 18, where it is partially limited by end wall 129 of the cover. Thus, the latch 120 has a set limit of reciprocation, which reduces the probability of accidental n is breaking when folding or closing the cover. Hole 127 can also be performed by preventing excessive movement from side to side.

In another alternative example embodiment of the invention, the cover 18 may be in the General case, the point of application of pressure on a flat surface, made as far as possible from the rotary axis 19, so that at the expense of the lever to get a greater gain in strength to overcome the effort required for institution of wires in the mortise contacts. In another additional alternative embodiment of the invention the upper portion of the latch (e.g., press 123) can be placed at a height slightly below the rest of the upper surface of the cover to reduce the pressure applied to the retainer 120 in the process of closing.

As mentioned, the cover 18 can optionally have the access zone 140 for testing and an area of 150 visual inspection. In a preferred embodiment of the invention, the access zone 140 for testing may have one or more holes, such as holes 141 and 142, which provides access to cutting-contacts (shown in Figure 5 and 7). For example, the openings 141 and 142 may be of sufficient size to provide access to the probe (or probes) directly to mortise the contacts in the closed position of the cover. You can use other shapes for the holes 141 and 142.

Also what about the, cover 18 may have an area of 150 visual control that allows the user to explore the mounted wire or check their location. Area 150 visual inspection may be made in the form of a hole or holes, such as holes 151 and 152, or in the form of an essentially transparent material (e.g., window or similar), located above the intended location of the wires, which enables visual observation. As an alternative zone of visual inspection can be performed on the other side of the cover. Area visual control enables the user to check the condition of the wires without removing the cover. For example, the user can check the wires, so that after installation to see whether the end of each wire directly from the end wall 114, 114' of the cover. This area visual control increases the likelihood that the wire is properly instituted in flush contact.

During operation, the connecting device 16 can be placed in a wiring closet, the camera, the hatch or lid, on places such as on the outer section of the unit for communication lines, which often is equipment with a dense layout (where the blocks are placed approximately one inch from each other), where physically difficult for the head of the t wire. Using the cover 18, as described above in the embodiments of the invention, it is easy to have it wire by placing the cover 18 at a comfortable angle, then closing it with the simple tap of a finger. While this connection can be performed without using a special tool. For example, as shown in Figure 10 - Fig, the number of wires you can create and connect as follows. For simplicity, is not considered a large number of other blocks.

As can be seen in the cut, shown in Figure 10, the cover can be set in the open position (to recline)to provide access to holders of wires 102. The wire or wires (usually a twisted pair) you can get into the holes of the respective holders until the ends of the wires will not be in close proximity or, preferably, not to touch the area of the rear wall 114 (or 114') of the cover 18. The cover 18 can be translated to the closed position (shown in figure 11)by pressing your finger (thumb) of the hand on the upper surface of the cap. The closing force is applied until such time as the latch 120 will not come into engagement with the T-shaped pin 27 of the base 21 (for example, you can hear a clicking or ticking). After closing the lid 18, as shown in figure 11, the wires 63 are secured in the mortise contacts 30 (in this example, the wires 63 are geared first end 91 mortise con who acts 30, whereas the corresponding wires for connection mounted on the second end 92 mortise contacts 30). The installer can then check the placement of the wires, looking around the section with insulation displacement contacts through the zone of visual inspection of the cover 18. And Vice versa, as shown in Fig, the cover 18 can be folded back, because the wires 63 remain fixed and connected with mortise contacts 30. For example, you can press the button 123 to display the cover disengaged from the T-shaped pin 27. A small directed at an angle upward force of the cover 18 can be opened without taking the wire from cutting contacts. After bringing the cover 18 to the open position it can accommodate an extra row of wires for connection with the wires 63, already established in the respective mortise contacts.

As is evident from the above, the installation and connection of the twisted pair of wires can be performed without special tools or special skills of a specialist. The replacement wires can be done without damaging the cover.

In an alternative example embodiment of the invention the connecting device, which is connected to the first row of wires 23 and the second row of wires 63 may be electrically connected to additional nearby wires. For example, as shown in Fig, for connecting pairs of wires 23 and 63 is an additional pair of wires or additional pairs of wires you can use the additional element, such as a jumper or a jumper 40. Retainer 40 may optionally have a cover 18', performed like described above. The body of the jumper 40 may have the contacts to splice (not shown)that connect the jumper with cut-in contact 30.

In an additional alternative embodiment of the invention, as shown in Fig, the cover 18 can be placed on the protective device 42, which can be placed on some or all of the connecting devices to prevent or reduce damage to wires and other relevant items from the sudden increase in the voltage or current in the wires (for example, protection against overvoltage and/or overcurrent protection current), for example, caused by a lightning strike. Protective device 42 is preferably made of insulating material such as the above insulating materials, and may further have a third grounding prong. Also, the protective device may have an element limiting voltage, such as dynistor (switching diode) or bidirectional symmetric dynistor, which has a very high resistance in the normal state, and which forms a short circuit when the voltage exceeds the specified value. The design of the jumper 40 and the protective device 42 may be similar to those described in betw the national application WO 2007/102983, which is incorporated here by reference.

As the retainer 40, and a protective device 42 can have the tabs, such as described above, to attach these elements to the base 21 of the connecting device, as it is obvious from the description to a person skilled in this technical field.

As mentioned, the connecting device may have a base and a number of caps placed on the upper and lower sides of the base 21. For example, on Fig shows another connecting device 16', which is the first row of lids 18, placed on the top or Paramakatoi" side 21A of the base 21, and the second row of covers, including broshennye cover A and B placed on the bottom or "cable" side 21B of the base 21. Cover A and V is broshennye cover, which means that each cover can cover a number of contact sections. As shown in Fig, cover A depicted in the open position, while the lid V - closed. Cover A and B can have some number of unit caps are made integral whole, all on a design similar to that described above covers 18 or the cover may have an alternative structure.

For example, on Figa and Figv shows an alternative cover A, the design of which lies in the displacement of the gel. A more detailed example of roofs and A shown depicted in FIGU the top view. In this example of the invention, the cover A can cover five different contact sections. Alternatively, the cover A can be constructed so as to cover a smaller or greater number of contact sections. Cover A is the main part 401 and the latch 420. The main part 401 can be made of the materials described above with respect to the cover 18, which may be essentially transparent or translucent. In this alternative example embodiment of the invention by means of retainer 420 can remove the front part of the cover 418 from the base 21 by clicking on the steam keys. The cover A can be connected, for example turning to install, with the base 21 through a series of pins or rotary axes 419 included in engagement with the respective supports, pins or rotary axes, made on the basis of 21.

In this case, as shown additional details on FIGU, the bottom of the cover A can have a number preventing the bending of the wire guide 415. As mentioned above, each contact section can be filled with a sealant, such as conventional gel (examples listed above)to prevent the entry of moisture and corrosion of the contact. In this example embodiment of the invention the guides 415 have the form of extrusion of a slope, ensure you close the lid of the force PE is alsaudia gel in the direction placed in the mortise section of the contact. Such movement of the gel better ensures that a required amount of gel to the connection point of the wire and cut contact.

In one example of the invention, the wire can make the cable side 21B of the substrate, using a special installation tool. As shown in Figv, the protrusions 407 can also be performed on the bottom cover 418, which helps to keep the wound wire in the holes mortise contacts and helps to prevent their separation. In addition, the cover 418 may also have guide recesses 409, made in the guide 415 in which to place the wires, keeping them in the transverse direction during installation/connection in the contact section.

As mentioned above, the connecting device in accordance with the claimed invention can be modified to connect a separate wire or individual wires, as well as to use the cover for a single wire or a set of covers for individual wires. For example, on Fig shows an alternative version of the cover 218 made with the possibility of the establishment and retention of a separate wire. Cover 218 has a main part 201, section 202, the retaining wire and the latch 220. If desired, the cover 218 can optionally have the access zone for testing and zone of visual inspection (not shown). the main part, which may be made of insulating material, has a generally rectangular shape to cover the contact section with insulation displacement contacts of the base 221, which may be part coupling devices, or may be a separate design, made with the possibility of connection to the circuit Board or other electrical or telecommunication device. The contact section can also be filled with a sealant, such as conventional gel to prevent the ingress of humidity and corrosion of the contact. The cover 218 can be made of structural plastic, such as described above. In one embodiment of the invention the material used for the manufacture of the cover 218 may be essentially transparent. In another example embodiment of the invention the material used for the manufacture of the cover 218 may be translucent.

While the base 221 depicted in Fig is only one contact section and has one cover, from the description of the specialist in the art it is obvious that, without departing from the scope of the invention, the base 221 may have a large number of sections with insulation displacement contacts and a large number of the respective covers.

Cover 218 has a section 202 that holds the wire in this example embodiment of the invention the holder is a separate wire is Yes. The holder 202 has a generally cylindrical or tubular shape, wherein the size of the hole 203 allows you to place and hold a normal wire, such as those described above. As shown, the conductor holder is preferably placed underneath the top surface of the cover and positioned opposite the cut-in contact 30 mounted in the base 221.

When mounting the wire you can get through the hole 203 until the end of the wire will not touch the area of the rear wall of the cover 218 (not shown). Cover 218 may also have a cross-section sample (not shown), which is made with mortise placement of the contact 30 when the lid is closed, so that when the cover serves a base 221, a transverse sample is in the appropriate position relative to the insulation displacement contact 30. The width of the sample cover a bit more thickness cut-in contact 30. By this means, similar to that described above, the cover 218 can be repeatedly opened and closed without touching directly mortise contact 30.

When this wire holder 202 may have a slot or longitudinal slot 204 that allows you to transfer and through mortise contact 30 to secure the wire placed in the area of retention. In addition, the conductor holder 202 can have sufficient flexibility so that clamping pressure is essentially U-shaped p is oresa mortise contact was more power clamp holder wire 202. Thus, when the cover 218 throw back, slit 204 allows you attached the wire to stay within the mortise of the contact.

Each side of the split holder wire can be advanced at the end of section 206, extending away from the slot 204. If such a widening at the end of the section easier to close the lid 218, while the wire remains enshrined in the mortise contact 30 and is not shifted or out of (respectively, stored electrical connection).

Cover 218 also has a latch 220. In this alternative example embodiment of the invention the latch 220 includes a pair of elastic in the form of columns of elements A and 224, with projections made with the possibility detachable engagement with the casing 21 in the closed position of the cover. The cover can be left closed until such time as the latch will not be specifically unlocked specialist.

In another alternative example embodiment of the invention as the base design, hosting mortise contact can be an individual design, made with the possibility of connection to the circuit Board or other electrical or telecommunication device. Thus, the cover described in the embodiments of the invention, can be used for direct connection the wires to the circuit Board or other device.

For example, on Fig shows an example of a connecting device 300 mounted on the printed circuit Board 350. The device 300 has a body 321 that hosts one or more insulation displacement contacts 30 that is used to connect the incoming wires to the circuit Board. Section with insulation displacement contacts is covered with a lid 18A is in the closed position) or cover 18V (in open position). The contact section can also be filled with a sealant, such as conventional gel to prevent the entry of moisture and corrosion of the contact. Covers 18A and 18B can be performed in the same manner as described above with respect to the cover 18. As shown in Figv, each mortise contact can optionally be made in the form of a pin 50 extending from the bottom portion of the base 321. These findings 50 can be connected directly to the circuit Board or the appropriate jacks for connections made by the other electric or telecommunication device.

Since the electric wires are usually connected to the coupling devices in the field, preferably to facilitate the process of installation/connections. For example, the conditions under which you must operate and assemble, can be severe, for example in the open air (i.e. unpredictable weather conditions), cabinets in the subway (i.e. RA the PTA in close quarters); and lack of qualified personnel. To simplify the work in such conditions, you can use linking devices with universal caps described in the embodiments of the claimed invention.
