The scope of the invention

The present invention relates in General to connectors for connecting cables to a target device or to each other, etc. and to methods for their installation and use. More specifically, the invention relates to connectors for coaxial cable and associated methods, in which the connector can be sealed from the environment.

Description counterparts

There are many applications where it is advantageous to connect the coaxial cable to the target device, to another coaxial cable and the like. Coaxial cable F-connectors, for example, are often used to complete coaxial cables, such as cable drop in the cable television system. Such coaxial cables typically include a Central or inner conductor surrounded by a dielectric or core which is in turn surrounded by the outer conductor or braid, which in turn is surrounded by the outer insulator, referred to as casing. F-connector is fixed on top of the prepared end of the coaxial cable with the shield, allowing the end of a coaxial cable to connect with a thread with a block of the target device with the thread.

The problem in the design of the existing coax the material of the cables, in particular, in applications outside the premises, includes unwanted penetration of humidity in the connector and the inside of the cable. This may degrade the quality of the work, for example, causing corrosion, affecting the electrical characteristics of the cable, which increases the contact resistance, which reduces the intensity of the signal, causing excessive RF (radio frequency (RF) leakage from the connector, etc. Experts are making various efforts to form a seal between the connector and the casing of the coaxial cable to remove this moisture. In the cable television industry known connectors, which include special sealing compounds and/or seals in the form of an annular seals for forming hermetic seals.

Famous covering the connectors (F-connectors) corrugated type, for example, in which the shirred cuff is included as part of the body of the connector. Special radial gomeroi tool, usually with clamping devices that form a hexagon, is used for radial corrugation corrugated sleeve around the outer shell of the coaxial cable to secure such a covering of corrugated connector type over the prepared end of the coaxial cable. Examples of such Gavrilova the different connectors are described in U.S. patent No. 4400050 in the name of Hayward, the rights to which are owned by Gilbert Engineering Co., Inc.; and in U.S. patent No. 4990106 name Szegda. U.S. patent No. 4755152 in the name of Elliot et al. describes the corrugated connector comprising a gel or other movable sealing material in the cavity of the connector to form a seal between the casing of the coaxial cable and the inside cover of the connector.

Known another form of covering the connector, in which the ring seal is used to secure covering the connector on top of the prepared end of the cable. Instead of crimp corrugated cuff along the radius of the casing coaxial cable, covering these connectors use a plastic ring gasket, which from the very beginning attached to covering the connector, but which detaches from it before it is installed covering the connector. Sealing gasket includes an inner through hole with the possibility of passing an end of the coaxial cable through the gasket before installing covering the connector. Myself covering the connector can then be inserted on top of the prepared end of the coaxial cable. Next, the sealing cuff is pressed in the axial direction along the longitudinal axis of the connector body when Edenites, at the same time sealing the casing of the coaxial cable between the sealing lip and the tubular support connector. An example of such a spanning connector with sealing lip is shown in U.S. patent No. 4834675 name Samchisen, which reveals covering the connector with sealing lip, known in the industry as "SNAP-N-SEAL", commercially available from the LRC (Thomas & Betts). Several commercial manufacturers of tools provide sealing tools for axial compression of the seal in such connectors. Unit CablePrep Ben Hughes Communication Products Company of Chester, Connecticut, for example, sells this manual sealing tool under the commercial name "terminx on".

The above-mentioned sealing connector "SNAP-N-SEAL" requires significant manipulation by the installer. The installer must disconnect the gasket from the connector, push the gasket over the end of the coaxial cable, and then install the connector and finally compress the gasket in the connector. During Assembly of the sealing sleeve may easily be lost, because it is usually small in size and must be separated from the installation of the cervix. Additionally, such connectors SNAP-N-SEAL" are usually more expensive than conventional crimped connection of Italy.

Another radial sealing covering the connector disclosed in U.S. patent No. 5470257 name Szegda. Tubular locking element protrudes in the axial direction into the open rear end of the outer collar or cuffs. This tubular locking element can be displaced in the axial direction in the outer clamp between an open position for the insertion of the tubular support in the prepared end of the coaxial cable, and squeezed position, the locking end of the cable to the outer connector. A sealing ring is mounted on the rear end of the tubular locking element for sealing the connection between the tubular locking element and an outer yoke, because the tube locking element is compressed in the axial direction. Such connectors were sold previously RCC Industries under the name "IDA". The o-ring is provided for the tube locking element is open and not protected before compression covering the connector in the axial direction.

In the application of coaxial cables it is well known that the collars or cuffs connector coaxial cable can be compressed inwards towards the outer surface of the coaxial cable to bond with him a connector coaxial cable. For example, in U.S. patent No. 4575274 in the name of Hayward, the rights to which are owned by Gilbert Engineering Comany Inc., opens the node connector for signal transmission, in which part of the body is in threaded connection with the nut part. The wrench portion includes an inner through hole in which is located the rim, and the rim has an inner through hole, through which is passed the outer conductor of the coaxial cable. When the nut portion screwed onto the part of the body, bezel jams inside for tightening the inner diameter of the rim, thus compressing the rim around the outer surface of the cable. In some cases, the connector is shown in U.S. patent No. 4575274 in the name of Hayward, cannot be established quickly as a simple clamp or compression tool. Instead, the mated threads of such a connector should be tightened, for example, using a pair of wrenches.

Known connectors coaxial cables typically require a number of components for attaching the cable to the target device, interface, etc. and try to do it, so as to obtain a suitable seal from the environment. The need for these various components adds the relative cost of these components, as well as the cost associated with maintaining inventory of parts, Assembly time, and works on the Assembly, installation and works the installation, etc.

Almost cylindrical part 116 has an inner surface 118, providing covering port 119. The inner surface 118 of the nut 110 is preferably, but optionally, threaded for tightening covered o 220 (Fig. 7), which is also preferably, but optionally, threaded. Nut 110 further includes an annular collar 120, located at the rear in relation to covering the port and passes radially inward from the almost cylindrical part 116 to provide holes 122 of the clip, which has a diameter d1the holes. The distal end of the annular collar 120 preferably has a beveled portion 124. The beveled portion 124 may have an angle, for example 45° in relation to the distal end 112 of the nut.

Cabinet element 140 has a Central passage 142, the distal end 144 of the housing and the proximal cones housing, located in front of the distal end of the housing 144. Cabinet element 140 further includes a proximal part of the housing 148 that contains the tab 150 at the proximal hull end 146. Preferably, the protrusion 150 is formed as a whole or a single part with the rest of the body element 140. The protrusion may include an elastic deformable material with "memory", or a flexible deformable material having limited memory or not having it. The protrusion may also contain material and/or be configured to be partially deformable and/or partially elastic. The tab 150 has an external diameter d2the protrusion, which is greater than the diameter d1the holes. The protrusion 150 preferably has a radius or anterior chamfer 152 to facilitate insertion of the protrusion 150 through the opening 122 of the clip. Front chamfer 152 may have an angle, for example 45° in relation to the proximal end of the housing 146 or longitudinal axis Lx. The annular ledge 154 combines the proximal part of the housing 148 with the distal Cabinet part 156. In the illustrated embodiment of the invention the proximal part of the housing 148 and the distal part of the housing 156 are each cylindrical, although the distal part of the housing 156 has a diameter of d3that is greater than the diameter d5proximal hull 148. Distal is the first part of the housing 156 is held in the axial direction from the proximal hull 148 and has an inner surface 158 with a tapered or narrowed part 160 of the inner surface. For example, a portion 160 of the inner surface preferably includes a tapered region 161, which tapers radially inward toward the distal end of the housing 144, and sealing cable casing region 162 of the surface. Sealing cable casing region 162 of the surface is the inner surface of reduced diameter, which is preferably nearly parallel to the longitudinal axis Lxconnector 100. The beveled portion 164 is located at the distal hull end 144. Sealing cable casing region 162 of the surface and the beveled portion 164 is divided in the axial direction of the conical region 161 from the distal end of the housing 144.

In the illustrated embodiment of the invention, the portion 160 of the inner surface includes a tapered region 161 and sealing cable casing region 162 of the surface located on the rear side of the tapered region 161. Part 160 of the inner surface can optionally consist of a single conical region 161, that is, solely from the sealing cable casing region 162 of the surface. The conical region 161 may have a nonlinear profile, such as the slope, which varies along its length. It is also possible to make the inner part of the surface is linear, that is, free from the tapered or narrowed area and/or equally serving with the whole inside is her surface 158.

Bearing 170 contains the distal end of the support 172 and the proximal end 174 of the support located in front of the distal end 172 of support. The distal end 172 of the support ends on the annular rib or ridge 176. Bearing 170 further includes protruding in the radial direction of the flange 178 bearings with outer diameter d4that is greater than the diameter d1holes, and greater than the diameter d5. Preferably the diameter d4flange bearing is equal to or greater than the diameter d2the ledge. The body support 180 is held back from the flange 178 of support. The body support 180 has an outer surface 182, preferably having at least one raised portion, for example the teeth 184, pushed forward from the annular rib or ridge 176. Teeth 184 can be tilted at an angle, for example, 20° with respect to the outer surface 182. The inner surface 186 of the body 180 of the support determines the channel 188 of support.

In Fig. 2 shows the method of Assembly of the connector 100, including the pressing nut 110 and frame element 140 together so that the protrusion 150 of the body element 140 is inserted through the hole 122 in the yoke 120. Cabinet element 140 or part, such as a protrusion 150, and/or the proximal portion 148 of the housing preferably is made of a material that is sufficiently flexible to allow the protrusion 150 the ability to bend radially inward to landing h is cut the hole 122 of the clip smaller diameter d 1. Front chamfer 152 protrusion 150 and the beveled portion 124 of the coupling facilitate the insertion projection 150 through the opening 122 of the clip. The clamp 120 thus is surrounded by the proximal part 148 corps corps element 140. In the axial direction of the clamp 120 is located between the lip 150 and the annular ledge 154 of the body element 140. Preferably the protrusion 150 and the annular ledge 154 spaced axially from each other a sufficient distance to allow for limited movement in the axial direction of the clamp nut 120 110 between the lip 150 and the annular ledge 154 before the nut 110 is tightened threaded connection threaded output 220 (Fig. 7). Limited movement in the axial direction of the yoke 120 eliminates much of the friction contact between, on the one hand, the clamp 120, and on the other hand, the protrusion 150 and the annular ledge 154. Consequently, the nut 110 during the rotation is connected with the proximal part 148 of the housing. By this mean the movement with the free rotation of the nut 110 relative to the bearing 170 and the body element 140, at least until the nut 110 is not delayed threaded on the threaded output 220 (Fig. 7).

Fig. 3 illustrates a support 170, panedwindow in partially fixed engagement with the United nut 110 and body element 140, and conker is tnie, bearing 170 is depicted in the position of insertion of the cable. As shown in Fig. 3, the nut 110, hull element 140 and bearing 170 is aligned coaxially with each other along the longitudinal axis Lx. The flange 178 of the support can move in the axial direction inside covering port 119, essentially cylindrical part 116 of the nut 110 from the illustrated position of introduction of the cable to the installed position of the cable (Fig. 6). Each of these provisions will be described in detail below with reference to the coaxial cable. The body 180 of the support extends from the flange 178 of support through the proximal axial portion 148 of the housing 140 and control passage 142 to the housing body 140, but with the passing of part 160 of the inner surface. The outer surface 182 of the body support 180 and the inner surface 158 of the body element 140 together to create an annular chamber 190 and the distal end of the inner surface 158 is formed with a rear entrance 192, receiving the cable.

In Fig. 4 shows an example of the coaxial cable 200 having the prepared end. Coaxial cable 200 includes a cable core containing inner conductor 202 and the dielectric 204 surrounding the inner conductor 202. Cable core may also include a foil outer conductor 206. Outer conductor (or braid) 208 surrounds the dielectric 204, and a protective outer shell 210 surrounds unediblewont 208. To prepare the coaxial cable 200 for insertion into the connector 100 outer conductor 208 unbent back on the outer surface of the protective outer casing 210 for opening outer conductor 208.

Next, referring to Fig. 5, will be described in detail the preferred method of connection of the connector 100 with coaxial cable 200. Bearing 170 is moved to the position of insertion of the cable, as shown in Fig. 3 and 5. In the illustrated embodiment, the end of the coaxial cable 200 is preferably moved in the distal end 142 of the housing in the housing 140 and passes through the rear entrance 192, receiving the cable up until the coaxial cable 200 is in contact with the distal end 172 of the support, while the end of the coaxial cable 200 preferably has a spacing from the inner region surface 160 and the longitudinal axis of the body support 180 and the coaxial cable 200 is preferably almost the same. Bearing 170 is moved in the axial direction of the housing 140. The distal end 172 of the support is inserted between the dielectric and the outer conductor 208 and, more specifically, between the foil outer conductor 206 and braid 208. This can be accomplished, for example, using industrial standard Assembly tools. Inner conductor 202, the dielectric 204 and foil outer conductor 206 are accepted thereby the inside of the channel 88 of the bearing in the rod 180 feet. Outer conductor 208 and the protective cover 210 is transferred through the rear entrance 192, receiving the cable, and in the annular chamber 190. Alternatively, the coaxial cable 200 can be passed through the Central passage 142 of the body element 140 before the body of the support 180 is inserted into the distal portion 156 of the housing.

Bearing 170 is then moved in the axial direction relative to the nut 110 and vessel element 140 in the installed position of the cable shown in Fig. 6. This preferably is accomplished using industry standard compression tools. In the installed position of the cable flange 178 of the support is directed along the axis ago, essentially cylindrical part 116 to position the flange 178 of support in the immediate vicinity of or directly adjacent to the proximal end 146 of the housing. The body 180 of support is sufficient in length to extend to the portion 160 of the inner surface, and more preferably by sealing cable casing region 162 surface portion 160 of the inner surface. As can be seen from comparison of Fig. 5 and Fig. 6, when the body support 180 is moved from the position of introduction of the cable to the installed position of the cable, the body 180 of support reaches the same axial position as the portion 160 of the inner surface. The annular gap between the outer surface 182 of the body support 180 and the inner surface 158 m is niche in positions along the axis, coinciding with the portion 160 of the inner surface (in comparison with the provisions located in the axial direction in front of him). Therefore, the outer conductor 208 and a protective outer shell 210 is compressed between the outer surface 182 of the body 180 of the support part 160 of the inner surface, and more specifically the region 162 of the surface, sealing the cable casing. Through this set first (or outer) moistureproof seal connector 100. This is the first moistureproof seal preferably is installed without requiring the use of any o-rings or sealing compounds, such as gel, thereby reducing the cost of treatment, although the sealing ring and/or sealing compounds may be added, if desired. The first moistureproof seal can also be installed without the use of a radial clamping of the tool or item, as it will require is known from the prior art connectors, thereby, in most cases, significantly shortens the processing time.

In the installed position of the cable shown in Fig. 6, the teeth 184 can limit the output in the axial direction of the bearing 170, past the annular ledge 154 of the housing 140. Preferably, the front tooth 184a rested on the distal end of the annular ledge 154 in progenitores cable. This junction may hinder the progress of a support 170 relative to the body element 140, thereby helping to prevent authorized separation or weakening of support 170 from the body element 140.

As shown in Fig. 7, the nut 110 is then secured by a threaded connection to the threaded covered the output 220. Free from rotational movement permitted between the nut 110 and body element 140 facilitates threaded fastening nut 110 threaded output 220. When the threaded output 220 is fed into the screw covering the port to the distal end 112 of the nut, the protrusion 150 is compressed between the flange 178 of the support ring and clamp 120 of the nut 110. Compressed ledge 150 operates to provide a second (proximal) moisture-resistant seal at the proximal end of the output connector 100 without requiring any additional sealing means such as sealing ring, other elastomeric elements or sealing compositions, such as sealing gels. The exclusion of additional sealing means and clamping elements or tools can significantly reduce processing time and reduce production costs. However, o-rings, other elastic elements or sealing gels and/or compounds may be added, if desired.

In predpochtite the flax embodiment of the invention, the connector is an Assembly of three parts and consists of nuts, corps member and support. The Assembly of the three parts can reduce manufacturing costs and Assembly time in comparison with connectors, consisting of four or more parts. It is clear, however, that the introduction of additional parts in the Assembly can also be implemented in the scope of the present invention.

Fig. 8 shows another preferred variant implementation of the connector 100A, as described here. The connector 100A contains nut 110, Cabinet element 140 and the support 170. Fig. 8 also shows an optional o-ring around the proximal portion 148 of the housing body element 140. In the illustrated embodiment of the invention the distal portion 156 of the housing is held in the axial direction from the proximal portion 148 of the housing and has an inner surface 158 with a constricted part 160 of the inner surface. Part 160 of the inner surface preferably includes a stepped region 161′issued or acts radially inwards, and the region 162 of the surface, sealing the cable casing. Region 162 of the surface, sealing cable casing has an inner surface of the reduced diameter d6which is preferably nearly parallel to the longitudinal axis Lxconnector 100A. The beveled portion 164 is located at the distal end 144 of the housing. Region 162 n the surface, sealing cable casing, and a beveled portion 164 pass in the axial direction of the stepped region 161′ from the distal end 144 of the housing. In a preferred embodiment of the invention the stepped region 161' consists of one stage. In other preferred embodiments, the implementation of speed region 161′ contains many steps. Preferably, the crossing speed region 161′ and region 162 of the surface, sealing the cable casing is formed at an angle of about 90 degrees. Preferably, the edge forming the intersection, contributed in preventing the release cable with connector, for example, preventing the output cable in the direction of the distal end 144 of the housing due to the frictional connection between the edge of the intersection and the casing of the cable.

Fig. 9 shows another variant implementation of the body element 140, as described herein. Cabinet element 140 is deformed in the axial direction, that is, the length in the axial direction of the body element 140 can be reduced. In the illustrated embodiment, the distal portion 156 of the housing acts in the axial direction from the proximal portion 148 of the housing and has an inner surface 158 with a constricted part 160 of the inner surface. Part 160 of the inner surface preferably contains stupenda the second region 161′ issued or acts radially on the inside, and sealing cable casing region 162 of the surface. Region 162 of the surface, sealing cable casing has an inner surface of the reduced diameter d6, which is preferably essentially parallel to the longitudinal axis Lxconnector. The beveled portion may be located at the distal end 144 of the housing. Region 162 of the surface, sealing the cable jacket, cut in the axial direction of the stepped region 161′ from the distal end 144 of the housing. In a preferred embodiment, the stepped region 161′ consists of one stage. In other preferred versions of the invention, the stepped region 161′ contains many steps. Preferably, the crossing speed region 161′ and region 162 of the surface, sealing the cable casing is formed at an angle of about 90 degrees. Preferably, the edge forming the intersection, assisted in preventing the release cable with connector, for example, preventing the output cable in the direction of the distal end 144 of the housing due to the frictional connection between the edge of the intersection and the casing of the cable. In the illustrated embodiment, corpus element 140 includes a deformable region 240. Deformable region 240 Pris is oblivaetsa to compression in the axial direction under the application of effort to compress in the axial direction. Deformable region 240 preferably contains at least one portion 241 with a reduced wall thickness. Fig. 9-11 illustrate Cabinet element 140 having a deformable region 240 that contains two parts with a reduced wall thickness.

In Fig. 10 shows one preferred implementation of the connector 100B, unveiled here and Cabinet containing element 140 in Fig. 9. The connector 100B is represented in the condition corresponding to the state after insertion of the cable, but to deformation of the body element 140. There is no o-rings, but optionally it can be introduced into the gap 232.

In Fig. 11 shows the connector in Fig. 10 after deformation of the body element 140.

In Fig. 10 and 11, the deformation in the axial direction of the body element 140 may be achieved, for example, by applying opposite forces of compression in the axial direction at the proximal end 174 of the support in the support 170 and the distal end 144 of the body the body element 140 so that the distance between the proximal end 174 and the distal end 144 of the body decreased in length with L1to L2. In preferred variants of the invention, the powered element 140 and bearing 170 are adapted so that the distal end 172 of support and region 162 of the surface, sealing the cable casing is displaced in the axial direction by predeformation corps element 140 and, at least partially overlap in the axial direction after deformation of the body element 140. Thus, the introduction and the clutch cable with a distal end 172 of the support preferably is facilitated before deformation, and the seal around the outer periphery of the cable casing by at least partial overlap in the axial direction as a result of deformation. In preferred embodiments, the implementation of the deformable region 240 is thrown radially inward after deformation, and optionally, but preferably, at least part of the deformable region 240 is adapted for coupling with the outer periphery of the cable after deformation, whereby is provided an additional step of gripping the cable with a distal seal and the compression provided by the field surface 162, cable sealing cover.
