The present invention relates to the connection between the electrical wires and, in particular, to an improved fixation of the wires in the modular connector for splicing systems, particularly those used for connecting multiple wire pairs of the communication systems. The device comprises a main body connector and removable design fixation wires attached to the connector.

Known systems related to electrical connection (copper) wires. One has found successful application of fashion is 14, 3945705 and 5030136 and supplied by Minnesota Mining and Manufacturing Co. (3M - patent holder of the present invention) under the brand name MS2. One of the designs of connectors MS2shown on Fig. 1, has a generally rectangular shape and includes a bottom part 1 of the housing upper part 2 of the housing, the base or lower protector 3, the cover or top of the protector 4, with many shifting isolation or samozaciskowy contact elements 5, each of which comprises a pair of U-shaped ends of the input terminal parts of the wires, and cut blades 6 for cutting the ends of the wires to the required length. In one embodiment, there is a 50 such contacts, allowing you to simultaneously connect up to 25 pairs of wires. There are various options connector MS2designed for permanent connections, as well as bridge or removable modules, designed for use in switching devices, coils disconnecting the load and add handling loops without interruption. There are also polyommatinae modules. Cover and base may be transparent to allow visual inspection of conductors. In addition, the base may be provided with ispytatelei may be sealed or inserted in certain of the connecting nodes. Cm. also U.S. patent N 4093334 on a special holder base for pre-termination and testing at the factory. The size of the connector and the internal elements may vary depending on the diameter of connectable wires. Connector MS2available in different models, designed for different diameters of wire and cable types, such as groups of clamps 10 and 25 pairs.

The design of the connector MS2allows you to remove the cap from the body connector terminals, which provides access to the wires to correct errors in splicing and maintenance of individual wires to these connectors, with many couples. The cover must also be removed when bond together additional buildings connectors in those implementations that allow binding of the vertical connector housings, each of which contains one or more groups placed in the clamps of the wires. Despite the fact that these teams krasivaya connectors meet all requirements of the standards on the mechanical characteristics of the equipment telephone communications may still offset wires from the points of attachment when working with connectors, i.e. with the cover off. First on the OK sorting and splicing, similar to that described in the patent 3713214 may contain devices to work with the wires in the process of splicing. This krasivaya head contains a coil spring that is designed for holding wires, and guides for individual wires, combined with the housing of the connector. This krasivaya head, however, is too cumbersome and difficult to use during maintenance operations dense wiring, although there are lighter options that provide minimal support and fastening. Cm. also U.S. patent N 4446617.

The way to facilitate removal of mechanical stresses in a modular connectors proposed in U.S. patent N 5030136 by adding details stress relieving, forming a single unit with the housing of the connector along its inner part. This addition, however, leads to an increase in the width of the connector housing and the increasing design complexity of the molding equipment. The main impediment to improved performance of the primary design MS2and any other existing structures, is the need to ensure compatibility with all other previously established connectors and lead snap, the ka of any improved system existing production processes. In accordance with this patent 5030136 not respond to requests concerning compatibility. More specifically, in the schema of an existing connector MS2there is no place for accommodation details, strong enough to perform the task of holding the wires. Any such item will be too fragile and will complicate the process of manufacturing or Assembly.

The task of providing a corresponding reduction in voltage in miniature, designed for a multitude of pairs of wires, connectors, directly related to the size of the wires used in the connectors. The part that holds the wires of the smallest diameter likely to experience undue influence on the part of the wires with the largest diameter, making it more difficult in these cases, the execution of the splice in the connector. This phenomenon is observed in which is designed for fixing wires and stress relieving geometric shape of two other existing structures described in U.S. patent N 3611264, 3772635, 3858158, 4262985 and 4423916. To accommodate the entire range of diameters of wires, these designs require the use of certain components, such as indexing plate. Simulation design MS2modified by use of the locking wire lighting fixtures what about in General is considered to be unsatisfactory due to the complexity of manufacture and operation. Timing patterns, described in U.S. patent N 4178055 and 4836803, have similar disadvantages. Conventional devices for relieving stress are also not compatible, including requiring the use of clamps (see U.S. patent N 4127312, 4444449), the use of corrugated or deformable side walls (see U.S. patent N 4097106) and is equipped with an insulated clamping surfaces (see U.S. patent N 4099822, 4236778, 4343529). In all these devices, a device for fixing the wire is made as a single unit with a block connector. There are descriptions designed for many of the pairs of connectors with worn or removable elements designed to reduce mechanical stresses, but they typically involve twisting all the wires together. Thus, in order to gain access to a separate wire, you must remove these removable elements that allow the movement of all wires in the area of the contact points; see U.S. patent N 4090764, 4488769, 4804342, 4822286, 4840581, 5030111 and 5158476. The hinge elements reduce mechanical stresses, which are mounted on the wires with clamps located at the ends of the bundles of wires have the same drawback (see U.S. patent N 4538873 and 4875875). Neko is abgene individual elements, reducing voltage to provide access to the wire connections; see U.S. patent N 4538873 and 5125850.

In General, all proposed still fit for fixing and reduce mechanical stress wires, considered in conjunction with the construction MS2have a number of disadvantages, such as the need to harmonize structures, limited performance, and difficulties in manufacturing. In addition, none of these structures does not allow placement of a fixation device of the wires on the selection, so that the device can be easily installed or removed from the chassis connector. They also do not provide flexibility in the application. It would therefore be desirable to devise an improved device for the fixation and reduction of mechanical stress of the wires for the mounting of the wires when the cover, allowing to overcome the limitations associated with the size and compatibility, and allows easy splicing wires by hand and the use of different fixation wires on one module connector. It would also be desirable to design a connector included separately installed fasteners and alignment of the wires on both storestate the invention provides a modular connector for mutual connection of the first set of wires, respectively, with the second set of wires, and in General includes an elongated body of the connector, with many shifting isolation contacts (IDC) located therein for establishing electrical connections between the respective pairs of wires, a removable cap mounted on the connector housing so that after installation on the specified connector housing cover is pressed first set of wires in the direction of one U-shaped end of the IDC, providing electrical contact of copper with the appropriate IDC, as well as an elongated plate fixing of cables, whose length does not exceed the length of the connector housing, provided with means for holding the first set of wires near the points of their connection with the IDC and cramping due to this, to minimize the violation of the electrical connections when handling the connector. A removable plate fixation wires is mounted on the body of the connector with a General orientation parallel to the connector shell.

In a more specific embodiment implementing the present invention relates to the modification of the hull connector MS2providing mechanical fastening plate fixation wires along the edge connector. Guide shutter along the edges of the body soma dovetail, and plate fixation wires provided with forming with it a single unit and mating with cavities protrusions in the form of a dovetail. This design principle allows the manufacture of plate fixation of the wires in the quality of a certain product and then installing the connector or in the process of Assembly of the connector, or after Assembly of the connector. Configuration details in the dovetail on the plate fixation wires is modified in such a way as to be able to insert or to fasten the plate to the module connector Assembly or during the final operations of manufacturing, or at the place of use. As installed on the housing of the connector plates are removable, it is possible to develop a variety of plates, including complementary geometric shapes, to extend the application of the base unit connector. Plates are easily installed and removed from the connector, depending on their specific functional purpose. As a material for the manufacture of plates, as well as the housing of the connector is preferably used elastic formed by injection molding a polymer that is flexible enough to be easy is to understand the main objectives of retention and alignment of the wires.

Description of the preferred embodiments of the invention

On the drawings, and in particular, Fig. 2 shows one embodiment of the housing 10 of the connector used in the module, designed for a multitude of pairs of soedineniya part 14, similar to the upper and lower parts of the body connector design 4000D MS2("4000D" is a trademark of 3M). And the upper and lower parts 12 and 14 contain many voids or channels 16 designed to receive individual wires and to combine them with relevant contacts from a variety of shifting the isolation contacts (IDC) 18. In the illustrated implementation, each IDC 18 has two U-shaped end, known in the art, which can be moved a part of the insulation, tight-fitting copper wire, and deform the wire, creating a reliable gas-tight connection when the simple operation of compression. Also provided many of the cutting blades 20 that are designed to remove excess sections of the end of the wires. The IDC elements and the cutting blade is made of metal, preferably of phosphor bronze and stainless steel, respectively, and held in the housing of the connector by using the various clips, walls and cutouts in the top and bottom parts 12 and 14. The slots extend all the way to the outer surfaces of the upper and lower parts 12 and 14, which allows the fastening of wires on opposite surfaces of the connector.

Also provided cover and about 3 in the previous design of the connector, that allows you to maximize compatibility with the existing design. And really with the exception of cavities in the form of a dovetail, addressed in the next paragraph, the design of the preferred embodiments the upper and lower parts 12 and 14 of the casing is identical to the previous design, which allows to minimize changes in the technological tooling and molds. Cover and base have the same surface structure as the previous design, to complement those on the upper and lower parts of the connector. In particular, along the edges of the cover and base are made hooks for removable engagement with the latches 19, performed along the edges of the upper and lower parts 12 and 14, and along the inner surface of the cover are ridges or protrusions designed to clamp the wires to the contact elements and the cutting blades when the lid or base tightly mounted on the housing 10 of the connector. On the cover and the base can also be guides, channels, studs, etc., intended for proper alignment of the wires. The upper portion 12 and lower portion 14 have respective edges 21 and 22 of a serpentine form, or with a sequence of arcuate cutouts 24, obespechenie on opposite edges of the body 10 of the connector, i.e., by cutting the wires. The cutouts 26 are useful in the initial stages of the splicing operation, then, when after cutting and removing excess wire through them no longer runs of wire, the hole can be used to enter the tips of the separation tool. The ends of the upper and lower parts 12 and 14, as well as the ends of the cover and the base preferably have a construction similar to that shown in Fig. 1, which allows the combination of components, such as a cylinder, for jointing or fixing to the frame or bracket. As the upper and lower parts 1 and 2 of the former design, the upper and lower parts 12 and 14 of the housing 10 of the connector are almost mirror reflection.

The main difference between the body 10 of the connector from the previous design is the many-shaped dovetail cavities 28, made in the side wall 30 of the housing 10 of the connector. The term "dovetail" is not limited to the designation only of the slot to the right of the trapezoidal cross-section, but in a broader sense refers to any cavity having an inlet opening that is smaller than the rear part of the cavity. In accordance with this cavity is designed for your area has a width or area, greater than the width or footprint, and maximum (peripheral) the width of the protrusion in the form of a dovetail exceed the minimum (input) the width of the cavity. In a preferred embodiment, the implementation of cavity 28 is limited to a complementary grooves made on the upper and lower parts 12 and 14, with a slant angle of 15-25o. Specialists in the art can appreciate the way in which the cavity 28 in the illustrated embodiment, the implementation of complementary geometric shape of existing models 4000D both in respect of the use of the connector in the process of splicing and maintenance, and process of forming the upper and lower parts 12 and 14. As mentioned previously, the cavity in the form of a dovetail 28 are aligned with the latch 19, which means that the cavity 28 are usually located between adjacent channels for the wires 16, since the latch 19 must also be located between the channels for the wires, in accordance with the arrangement of hooks on the lid and the base of the connector. The presence of cavities 28 on each side of the channel for the wires 16, are placed in series and parallel to the housing 10 of the connector, also contributes to the use of removable plates described below. As shown is of initely.

The shape of the cavities 28 in the form of a swallow's tail is visible in Fig. 2B as highlighted in part A. while this detail is more clearly depicts the dovetail in the incision along the interface between the upper and lower parts 12 and 14, the preferred embodiment also includes an additional circuit in the form of a dovetail cavities along the Z axis, i.e., the cavity is wider at its Central portion than at the ends adjacent to the latches 19. In Fig. 2B also shows the cut-outs 32, made in the lower part 14 and designed to accommodate IDC 18. In Fig. 2B more clearly depicts the internal channels 36, which may optionally be performed in the lower part 14 and which may form a test ports when the channels 36 are positioned opposite the corresponding channel in the upper part 12. Holes 38 are used to input the installation of the pins on the base of the connector.

In Fig. 3 shows the plate 40 of the fixing wires, referred to hereinafter as the plate separation of pairs of wires, which is designed for removable mounting on the housing 10 of the connector. The plate 40 of the separation of pairs of wires, there are many protrusions 42 in the form of a dovetail, the dimensions and location of which provide their e dovetail can be mowed or cut to facilitate their entry to the cavity. Plate 40 includes means for fixing the wires when installing the plate 40 on the housing 10 of the connector, and in the preferred embodiment, the implementation of this tool has many pins 44 located at the ends of adjacent rows 46 for the wires. The pins 44 and grooves 46 are arranged along both edges of the plate 40 in order to ensure the fixation of both the first set of pairs of wires connected to the upper part 12 and the second set of wire pairs connected to the lower part 14. The pins 44 preferably have beveled surface and provided with forming with them a whole wings or wedges 48 serving to separate pairs of wires and placing them in the slots 46, which is their alignment with the respective channels 16. Holes 50, preferably having an elongated shape, mostly carried out in the pins 44 in order to prevent deviation of the wedges 48 in the direction of the axis of the pin to facilitate the input wire and allow the pin to move away from the adjacent wires in the input process. The presence of the wedges 48 and openings 50 also allows efficient use of the plate 40 with a wider range of sizes of wires. The design of the pin can be slightly modified to use the appropriate grooves 46. These wings are quite thin, so that they can be broken when using wires of larger diameter, but tough enough to hold more than a thin wire in the grooves of reduced dimensions. Due to the above-mentioned arrangement of the cavities 28 between vzaimopogashajushchimi channels for the wires 16 in the housing 10 of the connector, the preferred embodiment of the plate 40 of the separation of pairs of wires connects each protrusion in the form of a dovetail with the pins 44. Rectangular protrusions 52 reach the lower part of the locking hole 19 in the upper and lower parts 12 and 14, counteracting the vertical pressure of the wires on the opposite side of the connector.

In Fig. 4A and 4B show the installation plate 40 split pairs on the housing 10 of the connector. As can be seen in Fig. 4A, the grooves 46 for the wires on the plate 40 is aligned with the respective cutouts 24 and channels 16 on the housing 10 of the connector. Landing in the dovetail is designed to provide fast, carried out by hand or hand tool installation plate 40 by means of its compression to the side wall 30 of the housing 10 of the connector, and equally easy separation. However, the plate 40 abessole further reduce the impact of mechanical stress on existing wires, avoiding or at least minimizing damage to the wires or their displacement from the IDC element. These functions only with a slight change in the size and shape of the site connector, and in addition, since the plate 40 is removable, it can be waived if, after splicing or maintenance space requirements become critical. It is shown in Fig. 4B a cross-section of protrusions in the form of a dovetail also illustrates a preferred device of the core 54 of each protrusion, giving it greater flexibility and thus making it easier to use when installing and removing the plate 40. The core 54 also allows you to increase the contact area on the peripheral end of the projections 42. The dovetail also provides a self-centering protrusions 42 in cavity 28. Specialists in the art it should be clear that the protuberances and cavities can be swapped, i.e., the cavity can be performed on the plate 40 and the tabs on the housing 10 of the connector, although it may lead to lowering of compatibility with other system components.

After installation of the plate 40 on the housing 10 of the connector wires can be STI 12, it is easier to insert them in the process of splicing operation manually. Wire supplied from below, can be inserted into the slots 46 for the wires in the plate 40 with adapter plate (not shown) having sloping edges, push the wires into the slots 46.

In embodiments of the housing 10 of the connector in which the connection dovetail is used for fastening the plate 40 to the housing 10 of the connector, both of these components are made of elastic material, preferably molded under the pressure of the polymer, such as polycarbonate, PBT polyester, a blend of polycarbonate and polyester, or a mixture of polycarbonate and polyurethane. The modulus of elasticity, reaching at least 689,5 MPa is preferred for fixation of the plate on the connector type "dovetail" with the divergence angle of the 15oand the modulus of elasticity in 10342,5 MPa fixation of cables allowing repeated flexing of the wire when bending tests under load 2,224 N, leading to the fracture on the outer edge of plate fixation of the wire while holding the wire in the IDC. Some plates provide positive results with a material having a modulus of elasticity of reaching 23443 MPa. The advantage is isoimage in the body of the connector, for example 23443 MPa). Use a softer material facilitates splicing of the most thick wires and minimizes the chances of accidentally cutting softer insulation of the wire, which may occur in some proposed hitherto devices relieve the mechanical stresses in the connectors. This design ensures the preservation of the required electrical characteristics of the connector with all kinds of wires.

As in all subsequent versions of the plates, the plate 40 of the separation of pairs of wires may be of any length, i.e., it can connect a different number of wires, though, and should not be significantly longer than the body 10 of the connector. Thus in one body, the connector can be used two or more plates in different functional assignments, or different fixation device wires can appear on the same plate, i.e., along the top and bottom edges. One such option plate shown in Fig. 5. In this embodiment, the implementation plate fixation wires takes the form of a locking strip 56 and one or more locking guides 58. The locking strip 56 is mounted on the housing 10 of the connector using the same connection, the AK in the process of merging does not change the shape of the connecting node. However, the locking strip 56 contains a few holes 60 along the top and possibly the bottom edges, which are designed to enter the vertical pins 62, made on the locking rail 58. The pins 62 can be provided with a flange, which engages with the annular edge or groove within the holes 60 to provide a positive locking action. Subsequent access to the individual wires can be provided by cutting out segment in the guide or by pulling the wire out of the gap between the guide 58 and the locking strip 60 (after the wire is raised with IDC). Locking rails 58 can be added to all connectors after the initial operation, splicing, or may be added later only to housing 10 of the connector open for maintenance after splicing. When the locking rail 58 is attached to the locking strip 56, it captures the wires between the edge of the locking strip 56 and a guiding element 58. The locking strip 56 is preferably provided with a serpentine shape edges 21 and 22, allowing better to combine Prov is Tina 40 split pairs, because it allows you to increase the force holding, without adversely affecting the performance of the splice.

In Fig. 6 shows an alternative lower portion 64 of the body, like the lower part of the housing of the connector used in the former case design connector 4005DPM MS2("4005DPM" is a trademark of 3M). The lower portion 64 of the housing makes the construction MS2suitable for packaging; each contact element has a IDC at one end and twisted the plug from the other end, and the plug passes through the slots 66 in the lower portion 64 of the housing. And in this case, made channels, limiting the test holes. The lower portion 64 of the housing is fitted with the same hooks as the cover of the connector in order to set the lower part of the housing 64 on the upper surface of the other of the upper part 12. The bottom 64 of the housing should be used unilateral plate 68 secure the wire, Fig. 7, in order to avoid intersection with plate separation of pairs of wires installed on the lower part of the packaged module. While the connection "dovetail" is also used for mounting the one-way plate 68 to the lower part 64 of the housing, the tabs in the th upper part 12, because of the geometric shape of the lower part 64 of the housing. A different number of grooves in the form of a dovetail 72 with a wider territory proposed to interact with a wider protrusions in the form of a dovetail 74, made on an ex parte plate 68. Unilateral plate 68 may also be attached to the side of the trim wire bundle connectors.

A variant of the implementation shown in Fig. 8, involves the application of side trim wire plate 76, having a set of pins 78, matching with test ports, placed on the body of the connector. Some of these pins can be provided with a flange or capture 80 that communicates with the inner annular channel or groove (not shown) made in the test ports. The plate 76 of the side trim wires, as well as any of the preceding plates can be adjusted in order to improve protection against moisture and sealing the connector by adding to the plate sealer. Depending on the functional purpose of the different inserts can be painted in different color, or may be transparent to facilitate visual inspection of connectors.

Dimensions to the t of a particular application. As an example, you can specify the following approximate dimensions based on the dimensions, a feature of previous designs MS2. Using the module connector 25 the length of the body 10 of the connector is equal to 16.5 cm, width 15 mm and the total height of the upper and lower parts 12 and 14 is equal to 7 mm channel for the wires 16 are located at a distance of 3 mm from each other. Plates have a height of not more than 10 mm, and the wire clamps (pins) on the plates provide the density of wires equal to at least 3 wires/see the Pins 44 have a width of 1.5 mm, with the wedges 48, exposed to 0.36 mm on each side. The holes 50 have a width of 0,76 mm Lugs 42 in the form of a dovetail have a maximum width of 1.9 mm, and the cavity 28 have a slightly greater peripheral width, and a slightly smaller minimum width.

Described constructions have numerous functional advantages. Because the plate is formed as a separate product, design details secure the wire is not limited to geometric features of the molding of the connector housing. Used for the manufacture of the materials can be selected, prepared and molded regardless of the material requirements of constructii plate and material satisfying the requirements of the application. The end user may be provided with a wide range of additional plates for various purposes, as attached to the connector and shipped separately for installation on the job site, depending on the destination. This will allow the user to have one connector, which when necessary can be some improvements. Additional plates are removable. If the dimensions of the bonded beam exceed the capacity of fixing wires at the splice, the user can simply remove the plate fixation wires. In the case of splicing manually need plates on the side of the trim wire connector after completion of the splicing manually eliminated. Their removal will reduce the size of the connector for splicing of the beam and will also allow you to use standard duct sealing. These plates can also be reused on another connector. All plate designs provide improved performance fixing wires of large diameter, as well as improvements in reducing mechanical stresses, even when using small wires that connected there are also several advantages in the field of manufacturing. Adding to the locking guide body of the connector mounted in the dovetail can be carried out on all the connectors. It is located within the original contour of the connector and does not change the compatibility of the connector. Meanwhile, there is a negative impact on the process of molding the housing of the improved connector, and ultrasonic welding improved connector Assembly. For the production of bodies of an improved connector does not require any change in the existing Assembly equipment. The plate can be fastened to the finished connectors using a simple clamp installation at the end of the existing Assembly line. All this allows you to easily change depending on the needs of a range of products, with no lowering of the production efficiency of the base of an improved connector. Change the range of products provides the necessary steps for forming and securing cheap plates. You can also minimize the amount of stocks of finished nodes with different geometric shape of the hull.

Although the invention has been described with reference to specific embodiments, it isany of the invention should be understood various modifications of the described embodiments, as well as alternative options for implementing this invention. For example, in Fig. 9 and 10 depict two alternative geometric shape of the attachment of wires. Obvious will also be other means of mounting plates, such as mushroom-shaped protrusions or small pins with flattened ends, which force is introduced in a cavity made in the body of the connector.
