## Abstract

Multi-wire group splicing in multi-wire telephone or like distribution systems, utilizing an at least three-sided distribution module (DM), the distribution module (DM) comprising an array of bridging slots (128, 130, 132, 134) in each of its sides (120, 122, 124, 126), and an array of disc type connectors (210 or 230 or 232) for interconnection of the respective prongs (502) of conventional prong type bridging modules (BM or 500) engaging the sides of the distribution module. By use of the distribution module (DM), additional or substitute multi-wire groups can be connected into the distribution system without interruption of service, and field fabrication of splices need involve only the "building" of prong type bridging modules (BM) at the ends of wire group sections of the system, with interconnection of the sections being simply by plugging of the prong type bridging modules (BM) into the distribution module (DM). Double prong type extender coupler means (EC) may also be used in conjunction with an in service distribution module (DM) in some instances, to add additional distribution modules (DM2), and therefore additional bridging module receiving sides to a given splice.

## Claims

### Claim 1

A multi-wire distribution module for use in field splicing in a multi-wire telephone or like distribution system, said distribution module comprising:
an elongate insulative body,
a series of electrical conductor elements of generally disc-like form arranged generally parallel to each other and coaxially of said body, and
bridging prong receiving slots arranged in the side faces of said body and in sets radially around each conductor element and in several rows longitudinally of said body.

### Claim 2 (depends on 1)

A distribution module according to claim 1, comprising four rows of slots arranged in body side faces with each side face arranged generally perpendicularly of the adjacent faces of the body.

### Claim 3

A multi-wire distribution module for use in field splicing and the like in a multi-wire telephone or like distribution system, said distribution module comprising:
an elongate insulative body with at least three longitudinally extending external side faces;
prong receiving bridging slots arranged in said body in longitudinal array in the at least three side faces of said body, and with one bridging slot in each side face laterally aligned with a corresponding bridging slot in each other side face of said body;
disc type conductors in substantially coaxial array longitudinally within said body, each such disc type conductor being in aligned relationship with a corresponding set of laterally aligned bridging slots and each conductor electrically interconnecting bridging prongs inserted in any of such laterally aligned set of bridging slots.

### Claim 4 (depends on 3)

A distribution module according to claim 3, wherein said disc type conductors are of generally circular form.

### Claim 5 (depends on 3)

A distribution module according to claim 3, wherein said disc type conductors are of ring form.

### Claim 6 (depends on 3)

A distribution module according to claim 3, wherein said disc type conductors are solid and of uniform thickness edge to edge.

### Claim 7 (depends on 3)

A distribution module according to claim 3, wherein said disc type conductors are of generally rectangular form.

### Claim 8 (depends on 3)

A distribution module according to claim 3, wherein each side face of the module body comprises parallel side rails with latching holes engageable with corresponding latching nubs on the sides of a bridging module or extender coupler associated therewith.

### Claim 9 (depends on 3, 8)

A distribution module according to claim 3 or claim 8, wherein said disc type conductors engage inner walls of said body, with inwardly projecting tabs standing inwardly from said inner walls and positioned to retain said disc type conductors in substantially equispaced, substantially parallel array.

### Claim 10 (depends on 9)

A distribution module according to claim 9, wherein each side face of the module body comprises parallel side rails with sloping surfaces at the ends thereof enabling disengagement of a bridging module or extender coupler from the distribution module by means of a prying action applied therebetween, as by means of a conventional disengagement tool of the wedging type.

### Claim 11 (depends on 3)

A distribution module according to claim 3, wherein the module body comprises two generally similar elongate body parts, assembled together by means of interengaged pedestals, joining holes, and heat seal tabs.

### Claim 12 (depends on 11)

A distribution module according to claim 11, wherein each said body half is identical to the other.

### Claim 13 (depends on 11)

A distribution module according to claim 11, wherein pedestals and disc type conductors are arranged alternately longitudinally of the body.

### Claim 14 (depends on 3)

A distribution module according to claim 3, wherein the module body comprises two generally similar body halves, each with two side faces, the respective body halves including interengaged end panels, the said body being of essentially completely enclosed form except for the rows of bridging slots.

### Claim 15 (depends on 3, 14)

A distribution module according to claim 3 or claim 14, wherein the interior of said body is substantially filled with non-conductive gel.

### Claim 16

For use in a multi-wire telephone or like distribution system for field splicing or the like, a distribution module for interconnecting bridging modules each of the type having an aligned series of bridging prongs each connected to a wire input, said distribution modules comprising an elongate insulative body with at least three external side faces, each with a longitudinally aligned series of bridging slots configured to receive the bridging prongs of a multi-wire bridging module, each bridging slot in the various module faces being laterally aligned with a corresponding bridging slots in the other external faces, and said distribution module further comrising an array of conductive discs arranged axially longitudinally of the module and each coplanar with a respective series of bridging slots, each such disc being engageable for completing the electrical circuit among bridging prongs inserted in the bridging slots laterally coplanar therewith.

### Claim 17 (depends on 16)

In combination with several distribution modules according to claim 16, a double prong connector comprising an elongate insulative body with two, oppositely facing opposed rows of prongs with laterally opposed prongs each electrically interconnected to the other, such insulative body and rows of prongs being configured to be assembled with two distribution modules, in contact with one face of each module, and electrically interconnect the array of conductive discs of each module, each to another in laterally coplanar relationship.
