A wide variety of cable splice connectors are currently used in the telephone industry which perform three The factors to be taken into account when designing connectors are the difference in the diameter of the wires to be extended, the connectors must be designed for use with tools johdo n handling and improve maintenance, and the need for even smaller module sizes.

With more than a billion pairs of extensions in the telephone industry each year, which involves a lot of human labor and material costs, hard work has been done to achieve a better systematic extension. The ideal simple cable splice connector meets all your desired extension needs.

It is therefore an object of the present invention to provide a simple cable splice connector which implements all end, branch and bypass splices and which accepts an aluminum and copper conductor over a wide range of 2,58846 in such a basic connector. Such a connector should not involve high-cost post-encapsulation processes because it incorporates a shell.

The above object is achieved by the present invention, the features of which are apparent from the appended claim. The connector includes a three-part basic extension unit: a conductor strip, a connector body and a cover part. Johderima makes use of conductive or guiding teeth with ridges and a flat section alternately, splits the pairs of wires and acts as a temporary holder of the wire in place when the wires to be connected are compressed.

The connector body includes a double-ended slotted contact element. The top of the body is similar to the top of the guide bar and performs the same functions.

On the other side of each guide and guide strip there is a cantilever beam which supports the conductor against the stop bracket of the connector body. The beam or protrusion helps make it possible to use conductors of different sizes, such as U.S. Pat. wires with a standard marking between 26-20.

The connector body or module is locked to the conductor ground by means of a spring. In this process, the slit-like contact element contacts the insulation and makes contact with the wire while the connector module presses down on the wire on each side of the contact element, securing it tightly in place.

The contact element of the connector module is of the type described, e.g., in U.S. Patent No. 3,696,522. However, in accordance with one aspect of the present invention, each element may be joined by a central thin strip-like portion of similar contact elements arranged in a bypass connector module attached to two parallel on a track or rail made on the other side of the connector module. The strip portions are open through the same straight slots when they are in the wall of the connector module and are normally fully protected by a shell. According to another aspect of the present invention, the conductor strip and the connector module include wire slots having horizontally bendable walls so that attachment and adhesion of the wires is possible in a normal butt joint. The adhesion of the wires pressed into the teeth of the connector module in the vertical direction is achieved by cantilevered beams built into the cover part of the connector module. The latter is attached to the connector module by the same type of mechanism as the connector module is attached to the conductor ground.

5,58846

According to a further feature of the invention, the guide strip, the connector module and the cover part comprise vertical end grooves of standard size, which help to make connections and cut the wires by means of either a machine tool or a hand tool.

Using the extension connector method of the present invention, the extender first places the end grooves of the guide strip in the guide guide grooves of the tool. After using the alternating rib ridge of the father’s teeth with visual and physical guidance, he quickly places it in place and handles the pairs. The end of the workpiece is placed in a bar and the wires are pressed into place. Workpiece head Then jump one set of wires. The connector module is then placed on the same workpiece guide strips, the other wires are placed on the teeth of the connector module, and then the workpiece is again used to compress the wires downward. The rod contact with slots in the connector module penetrates the insulation and forms electrical contacts with the wires in the guide bar and module. The ends of the wires connected to the module are also cut off and mounted on the lockable guide bar of the module. Finally, the cover part is guided through the same grooving strip and is pressed into the module in a lockable manner.

In order to form a bypass connector, the end extension thus formed is removed from the workpiece in accordance with one feature of the invention and rotated 90 ° and repositioned on the workpiece through second end grooves located in the connector module. In this direction, when installing the bypass connector, the tracks or guide rails of the connector module face upwards to receive the bypass connector.

The invention will be described in more detail below with reference to the accompanying drawings, in which Figure 1 is an exploded perspective view showing a cover strip, a connector module and a cover part of a module.

The structure of each part as these parts together with the bypass module of the two-wire end splice will first be explained and will be followed by an explanation of the operation of the connector and will include the functional features of the connector.

The two-wire end joint is shown in Figure 1 and comprises a conductor strip 100, a connector module 200 and a cover portion 300. This group connects at least one or more wires of the first group to one or more wires of the second group, respectively.

J thin

Figures 1, 2, 3A-C show a conductor ground 100. It includes a lower body, generally designated 101, and generally has a flat lower surface 102 and a side floor surface 103. The end wall 10 rises vertically from the body 101 and includes a vertical female guide groove 105.

A plurality of spaced apart teeth 106 rise vertically from the body 101. Alternately, the teeth 106 have a flat top surface 107, and the other teeth 106 have a tip-like top 108. Each tooth 10b is positioned slightly backward from the side edge 109 of the guide bar 100 to form a narrow edge portion 109a. Each tooth 106 includes a tongue-like or latch-like portion or protrusion 110 on its front surface at approximately half its height.

Between each tooth 106 and along the back of the rib 100 there are slits 111 formed by adjacent upwardly directed wool portions or arms 112. The arms 112 are formed by two vertical through slots 113 with an arcuate top 11M located directly behind each tooth 106 and connected to it by a ridge 115 · If the grooves 111 have no conductor at all, the arms 112 are vertical and substantially separated from each other by a constant distance. When the conductor 241 is inserted into the slot too, the arms il 2 deviate horizontally near the conductor and due to their hanging direction towards each other in the area above the conductor, as shown in Fig. 1. This counter-bending acts as an additional clamp and secures the conductor such as conductor 241. .

The entire back surface of the conductor 100 has a flat surface 117 with an edge door 118. The surface 117 takes care of cutting the conductor, as will be explained later. The area is periodically cut by slits 119 beveled into gripping wings 120. Each slit 119 is preferably positioned laterally aligned with the teeth with the sharp-toothed tooth 108 and thus out of alignment with the wire groove 111.

Figures 1, 2, 3A and 3C show vertically the wire delimiting members comprising a beam-like protrusion 116 tensioned above the side walls 103 and between each tooth 106 in a straight line with each wire slot 111 and preferably nominally flush with the slot 111. Beam 116 is not attached to adjacent walls of the tooth 106, and is flexible enough to conform to contact with the side floor portion 103. Each beam 116 extends past the vertical surface of the tooth 106, as seen in Figure 3A.

A vertical gap 121 is formed between each of the two ridges 115 and between the adjacent inner surface of the upwardly rising portion 114 and the tooth IQu. The slot 121, as seen in Figure 1 and Figure 3A, extends below the plane of the conductor slots 111 to form a recess portion 122. The slots 121 receive conductive members, such as a double-ended slot contact element 219 mounted on the connector module 200, and pierce the conductor slots 111. insulation of the conductors located between the arms 112 and the cantilever 116. The recess 122 may contain a protective compound such as, for example, polyethylene, a polybutylene compound, or the like, a non-conductive, non-flowable, normally highly viscous material that protects the ends of the cut wire from water and corrosion.

As previously mentioned, the splice connector in this connection is modular and is made, for example, of five-pair 6 58846 or 25-pair modules. In the latter case, according to a further feature of the invention, it is preferable to make every fifth tooth, such as tooth 106A in Figures 3B and 3C, wider than the others. This avoids misplacement of the five-pair connector module in any non-real teeth.

the connection module

The number 200 denotes a connector module, as shown in Fig. 1. The easiest way to describe the complex internal structure of the connector module 200 is to show the module shown in Fig. 1 in two parts, the front 200A in Fig. 4A and the rear 20013 in Fig. 4B. it is clear that the term connector module refers to the whole module assembled and is used in practice as shown in Figure 1.

Fig. 5 shows a rear portion 200B having a rear surface 201 with a lower edge 202 and a groove 203 and downwardly extending arms 204, each provided with two rearwardly curved engagements 205. The arms 204 lock into notches 119 in the guide edge 100 · The rear surface 201 terminates at the upper edge or flat portion 20G , which includes a groove 207. The upper edge 206 acts as a conductor cutting member in the manner described. A plurality of receiving slots 208 are located at the top edge 207 with the inlet vanes 209 as they lock the tongue forks 305 of the cover portion 300.

Along the top edge 206 are a plurality of vault-like tops 2.10 which are substantially identical to the tops 114 of the conductor bar 100. The vaulted roofs 210 of the tops have chamfers 218. The tops 210 include two vertical passage slots 211 in each, with this structure creating upwardly directed arms 212. A conductor gap 213 is formed between each adjacent two arms 212 and the corresponding adjacent tooth 214. In front of each top 210 has a flat top surface 215, while the others have a bristle top surface 216. Each tooth 214 is secured to a respective top 210 with a narrow ridge 217 · It is preferred that one or both sides of each brush-like roof portion 108 and each brush-like roof portion 116 be identically color coded, such as blue, orange, green, brown, blue-gray. The color coding of the roof sections 108, 216 helps to find the point that correctly continues each separately color-coded pair of conductors.

The inner cavity of the connector module 200 is best seen in Figures 4A, 4s, 5 and 6 starting from the contact element 219 and its attachment.

7 58846 .Each contact element 219, as shown in Fig. 6A and can also be seen in Fig. 1, is in principle an elongate conductive member comprising fork-shaped end portions 223Λ forming a wide-mouth inlet into end slots 223 · The wide-inlet shrinks from the corresponding end slit 223 slowly shrinking shape. The thickness of the contact element is substantially smaller in each fork-like end portion. The grooves 223 extend toward the narrower intermediate portion 220 and terminate within the body of the element 219 at the point where the body begins to deform at 221.

A plurality of radial or semicircular aserm surfaces 222 are molded into the interior of the module at locations that form a space between adjacent semicircular portions 222 flush with the slit slots 213. Thus, the element 219 is mounted on a semicircular surface 222, as can be seen in Fig. 1, and places the upper insulation piercing slot 223 on the same line or opposite the conductor gap 213. The lower insulation piercing gap 224 is, when the module 200 is in place, a recess 122 that the lower slot 224 is on the same straight line or opposite the cord slot 111.

The contact elements 219 mounted on the surfaces 222 are disposed for mounting in a recess portion 225 formed between the rear portion 212A of the upwardly adjacent arm 212 of the adjacent ridges 217 and the rear portions 214 of the adjacent tooth 214. Element 219 and lower slot 224 pass through tunnel 253, shown in Figure 6 and in cross section in Figure 1.

As can be seen in Figure 4d, the front end floor portion and the gap 213 include a stop surface 226 between each tooth 214. The elongate top stop bracket 227 is shown in Figure 7 and has a downwardly shrinking surface 228 that coincides with the stop surface 226 shown in Figure 1. The bracket 227 leaves the upper device or guide 229 and below it is the lower guide 230. The guides 229, 230 receive this bypass connector. according to the invention in a manner which will be explained. The tracks 229, 230 are provided with a row of spaced-apart locking openings 231. The vertical surface 232 between the rails 229, 230 includes a plurality of upwardly directed walls 233 that form a dielectric breakthrough between the contact element merits of the bypass connector to be explained. Bypass slots 5 88 4 6 234 are provided on the surface 232 at the center portion between each adjacent wall 233 and on the same straight line as the taper 220 of the pin terminals 219 with shrinkable inlets as shown in Figure 7. The bypass slots 234 form one additional electrical input to each contact element 21.

Below the lower track 230, a base stop bracket 235 is molded at the bottom of the module 200. Separate locking holes 236 are provided along the length of the bracket 235 so that the module 200 can secure the guide wire 100 above the teeth 106 and in a locking connection with the locking bracket 110.

The interior portions of the module 200, shown in Figure 6, include arcuate portions 257 terminated in a downwardly projecting lana by clamps 238. Slit-like contact elements, as seen, are mounted behind brackets 237, 235. When the connector module 200 is mounted on the conductor strip 100 through which the conductors are pushed in, the wire clamp 238 first directs or bends down each insulated conductor located in the slot 111, thereby ensuring that each conductor is then securely attached to receive the contact element 219. .

Each alternating arcuate portion 237 is provided with a slot 239, as seen in Figure 4, and allows a wedge (not shown) axially positioned below the alternating mounting surfaces 222 to lock or block the surface 222 and the guide bar 100. a space between the tooth surface 107 to maintain dielectric strength between adjacent contact elements 219.

Centered directly behind each wire clamp 238, a cavity 240 is provided for the stopped conductor, and this allows each end of the cable to be encapsulated or surrounded by a shell to maintain di-electrical strength between adjacent conductors.

The cavity 240 is separated by walls 243 molded between each leg 204. The shell is good to place in the cavity 240 in advance.

Opposite the notched lower edge 202 of the connector module 200 is a front bracket 235 which acts as a stopping part and has an inwardly open oblique surface 242.

As seen in Figure 3A, the guide bar cantilever beams 116 extend beyond the leading edges of the teeth 106. When the module 200 is pressed down onto the conductor strip 100, the bracket 235 acts to make contact with an insulated conductor, such as conductor 241 on the beams 116, deflect or bend the beams 116 and conductors downward until the locking holes 236 lock into the locking projections 110 of the bar 100. 241 is securely locked in place by bracket 235.

9,58846

The connector module 200 includes vertical female guide grooves 244 at either end that allow the module 200 to be mounted on the pad portion of a hand or machine operated extension tool with teeth 214 facing up, as will be explained. A horizontal female guide groove is also provided on the sides of the module 200 to allow it to be mounted on the tool pad flange with the bypass connector mounting rails 229, 230 facing up.

With respect to the teeth 106 of the lead bar, the module of the teeth 214 every fifth tooth is wider (not shown) to prevent misalignment of the cover portion 300. Each of the teeth 214 is provided with locking projections 246.

It will be appreciated that the portion 247 detailed in Figure 4A resembles a spacer capsule and the L-shaped grooves 248 are merely casting details that assist in assembling the two portions 200A, 2003 by pushing the portion 247 into correspondingly shaped openings 24'3.

The tongues 250 of the part 2003, as shown in Figure 6, lock into the grooves 248. The plug portions 251 of the part 247 come into their female counterparts through the assembly openings 252 as shown in Figure 5. The plugs 251 are then flattened with the rear surface 201 of the module. It is obvious that there are other ways in mind as a person skilled in the art when constructing a module.

Structure of the cover part

The cover portion, indicated by reference numeral 300 and shown in Figures 1 and 8, generally includes a flat roof portion 301 having a longitudinal groove 302 that allows the use of a tool punch or press spatula or blade. The vertical guide groove 303 at each end receives the asermusk bracket of the tool when the cover portion is to be assembled for the connector module 200.

The bottom of the rear edge 304 of the cover portion 300 is continuous except for the leg portions 305, each of which includes two rearwardly curved wings 306. The legs 305 engage the receiving slots 203 in the connector module 200. The notched portion 207 of the module 200 engages the edge 504 and the lateral region 307. the side has regions at different levels extending into wire recesses 308, each of which coincides with the conductor gap 213 of the corresponding module 200. Above each wire gap or cavity 308 is a wire press 309 formed by a downwardly hanging or downwardly directed ridge, the bottom surface 310 of which is flush with the upper roof portion 311 of each cavity 308. The encapsulating sealant is pre-positioned in the inner cavities of the cover portion 300, which includes the cavity 308, the walls 315, and the areas below the beams 316.

When the cover portion 300 is in place with the module 200, the upwardly extending portions 210 of the module allow the chamber portion 200 to form chambers defined by the spaces between each press portion 309 and the roof portions 312, the latter contacting the chamfered portions 218 of the upwardly extending portions 210.

Arranged along the front walls 313 of the cover portion 300 are a plurality of spaced locking apertures 314 that are similar and perform the same function as the splicing apertures 236 of the module 200. The lower edge of the front wall 313 includes spaced apart walls 315 that receive a beam 316 that bends as it comes into contact with the conductor on the pressing surface 226 in the module 200. The flexible beam 316 has the same purpose and basic structure as the beam 116 of the conductor 100.

Function of Johderina, connector module and cover part

The two-wire butt joint assembly shown assembled in Figure 11 is compressed using the tool shown in Figures 12A, 12B and 12C. The tool, denoted by reference numeral tOO, includes a substantially base or flat portion 401 having a longitudinal slot 402 that is just wide enough to closely accommodate the width of the guide bar. Ridge 403 normally rises from the slot 402, which abuts the female guide slots 105 of the guide bar 100, then the guide groove 24 4 of the module 200, and finally the guide groove 303 of the cover portion 300. To ensure a tight fit, the ridges 403 can be spring locked or spring loaded (springs not shown).

The main body 405 is pivotally attached to the base portion 401 by a pivot arm 406. The main body 405 comprises a protruding part 407 »from the bottom edge 403 of which a plurality of protrusions 409 protrude · a plate or wing part 410 is mounted behind the protrusion disk 407, which is preferably extensible behind the protrusions or retractable.

For assembly, the guide strip 100 is placed, as described, on the tool base 401 with its teeth 106 facing upwards. The insulated conductors 241 are then loosely placed in the conductor slots 111 upwardly between the arms 112 and between the respective spaced teeth 106.

When all the conductors are in place, the main body 405 is turned to its position above the bar 100 and the protruding rod 407 is forced downwards, whereby the spaced apart protrusions 409 press the corresponding insulated conductor 241 firmly down into the slot 111 and cause the arms 112 to become horizontal. The penetration of the cantilever is limited by the impact of the bottom edge 4OS of the cantilever bar on the flat upper surfaces of the guide bar 100 107 ·

At the end of the downward working step, the blade or plate grinds the conductors on the surface 117, which acts as a leucus as shown in Fig. 3. The main body 405 is then turned away and the connector 200 is placed on the workpiece and is brought into contact with the conductor bar 100. . The workpiece head is then turned to its position and lowered.

By again pressing the connector module 200 against the flat top surfaces 213, the main body 405 first causes the lower insulation piercing gap of each element 213 to strike the conductors 241 by splitting the outer insulation and forming a strong electrical and mechanical connection to the underlying wire. When this connection is made at the end of the downward stroke, the branches 204 engage the slots 119 of the conductor strip 100. Similarly, the locking projections 110 engage the locking holes 236 of the module 200, thereby achieving a strong engagement of the module 200 with the strip 100 below. consisting of the end surfaces 253, 254, 255 of the connector module, a sealing compound is placed and also this sealing compound is placed in the slot 21 of the conductor strip 100, and the electrical connection is thus protected from the environment.

The main body 405 of the joining tool is raised again and turned back. The spreader then uses the ridge roof portions 216 of the module 200 to extend its pair in the same manner as the ridge roof portions 108 of the lead strip 100 were used.

In this way, the pairs of conductors become selectively connected to those mounted on the conductor strip 100 and assembled on the module 200 in exactly the same manner as described when assembling the conductors on the strip 100. The cantilever rod 407 joins in the same way to stop or press down the conductors on their stop surfaces 22b, thus connecting these conductors and upper insulation With 223. The wing or plate portion 410 cuts the ends of the conductor using the surface 206 as a cutting pad.

The main body 405 is retracted again and the cover portion 300 is placed on the ridges 403 · The last downward stroke of the main body 405 causes the vertically bending beam 316 to hit the jontin. The beam 316 forms a stop bend each caused by its compression against the stop surfaces 226, the bracket 227 and the upper rail 229 · Finally, the arms 305 of the cover part 300 engage the receiving slots 208 of the module 200 and the locking projections 246 5 884 6 hit the locking openings 31 of the cover part 300.

In addition, the protrusion Ilo acts at one point on the conductor 2i1 and the horizontally bending upwardly directed arms 112 acting at a proximal second conductor point form a rigid support for the conductor near each side of the contact element 2V) thus preventing movement of the conductor in the contact area.

The alternating workpiece operation should be performed by pressing the connector module 200 into the guides above the guide strip 100, then pressing the wires into the top of the connector module and then pressing the connector module onto the guide strip, and sealing and cutting the wires at this stage.

A further embodiment of the invention is shown in Figures 6 and 8. A vane or plate performing the function of a workpiece plate is added directly to the connector module. As can be seen in Fig. 6, the plate tiiO hits the slot 261 of the mod Ui m 200 so that the outer surface of the plate is substantially flush with the inner surface of the females 20 * 1. The die 262 is also flush with the same surface and protrudes about 1 mm below the wire press 253.

In the same manner as in Fig. 8, the plate 320 is mounted in the slot 321 of the cover portion 300 with the outer surface of the plate flush with the inner surface of the branches 306 and the plate edge 322 extending about 1 nm below the bottom surface 310 of the wire press.

uevyt 2t> 0 and 320 can preferably be made of ceramic or non-woven material or the like so that it is nova enough to split a relatively soft metal, sufficiently non-brittle and so as to have good insulating and dielectric properties. The board can be attached to the mounting slots with a suitable adhesive. it should be apparent from the foregoing that the upwardly extending arms 212 and the upwardly extending arms 112 of the guide bar are both rigidly attached to the cover and bottom ends. The wire slits which they thus form are made in such a way that the presence of larger-diameter insulated conductors between them causes the arms to retract in the contact zone. the bone stems from the adhesive close around the conductor as shown in Figure 1.

based on the diameter of the wire when the module 200 is adhesively mounted in place, the beams 116 may in fact be in contact with the floor portion 103 on the side of the guide strip; and the insulation of the conductive 211 can in fact be reshaped.

! 5 58846

The operation of the lower support 235 and the operation of the guide bar beam 116 are adhesively attached to conductors of different conductor diameters so that the degree of flexibility of the beam 116 is changed.

This is due in part to the fact that the cantilever beam is suspended from the inner point outwards between adjacent teeth in a normal rest position above the inner floor section. The same phenomenon interacts with the cantilever beams 316 in the cover portion 300 and the holding pins 226 in the module 200.

The guide 100, the connector module 200, and the cover portion 300 are preferably made by a die casting process known in the art. The materials can be polycarbonate, polyamide or polystyrene or a related polymer, such as ABS resin, all of which have good mechanical strength and rigidity as well as suitable electrical insulation.

bypass Connector

As can be seen in Figures 9 and 10, a good way to show the structure of the selected bypass connector is to show the two parts 500Λ and 500B from which the connector is assembled. A bypass connector, indicated at 500, includes a rear surface 527 having a flat portion 515 that rotates from one end wall 505 to another end wall wall, not shown. The edge door 514 is provided in a flat portion 515 as well as the slots 516 with lockable inlet vanes 528. The locking projections 525 are made on the rear surface 527 and the front surface 529, as shown in Fig. 9.

The conductor slots 530 open into the plane 515 and are formed between adjacent portions 508 with a vaulted roof.

Two vertical slots 509 in each upwardly rising portion 503 form horizontally flexible arms 510 which receive conductors in the manner described, e.g., in connection with the arms 212 of the connector module 200.

In front of each upwardly rising portion 508 is a tooth 501 associated with a corresponding upwardly rising portion 508 by a ridge 507. The recess portion 511 is formed by adjacent ridges 507, dorsal surfaces 510A in adjacent upwardly directed arms 510, and dorsal surfaces 50p of adjacent teeth. The recess portion 511 is similar to the recess 225 shown in Figure 1 and serves to receive and accommodate a double-ended notched metal contact element 504, which may be, for example, similar to the element 219 shown in Figures 1 and 6a.

The cavities 520 are made to remove encapsulation or coating material during the assembly step. Preferably, the two pieces 500A and 5003 are cast separately and then joined together by pushing the silenced ridges 519 into the molded grooves 523 as the semicircular portions 522 engage through the semicircular openings 52'i made in adjacent downwardly directed ridges 525.

The slots 530 are substantially flush with the floor portion 526 adjacent each tooth 501. The outer side of each nail 501 has locking projections 512. Each alternating tooth 501 has a brush-like roof portion 503 and a flat top surface 502 between each inner tooth 501.

A stop bracket 517 with an inwardly curving bevel portion 513 is positioned near the floor portion 526 between each of the two adjacent teeth 501. The bevel portion 513 extends upwardly to the floor portion 526.

According to another feature of the invention, the roof portion is identical to the roof portion 300 and securely engages the bypass connector 500 by engaging the slots 516 with the arms 305 and the protrusion 512 into the locking holes 31A. The effect of the flexible beam 316 on the conductor 5äl in the slots 530 is the same as already described previously associated with the beam 316. Similarly, the cover portion 300 locks in place, the bracket 517 stops the conductor 5 * 11, and the wire clamp 309 in the cover portion 300 presses the conductor 5 ^ 1 into the slot 530.

the helical 50a te-like connector ends 50äA extend downwardly and have a lower edge 506, as shown in Figure 11. The connection of the bypass connector 500 to the connector module 200 is accomplished by locking the protrusions 525 into the openings 231 as the ends 50äA extend through the bypass slots 23'4 to the portion 220 of the contact element 219 of the connector.
