Abstract
Abstract Apparatus for the solderless splicing of a multi-element cable such as a telephone cable comprising a novel splicing device consisting of a cable retaining member and a top member mountable thereon and carrying a plurality of incisive connectors having depending legs with a cutting slot therein. For splicing two cables, the cable ends are first inserted and mounted in the opposite ends of the cable retaining member, the leads of each cable are laid out in a corresponding sequential order in slots at the opposite sides of the member, and the top member is inserted over the cable carrying member so that the incisive connectors engage the individual leads of both cables, cut through the insulation thereof, and make electrical contact with the wire within each lead to interconnect the leads of the two cables. For splicing a cable to the leads of outside branch wires, the cable leads are laid out in the slots at one side of the cable retaining member, the top member is inserted thereon, and individual branching clips carrying the branch leads are inserted at the other side of the device.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
237 words
A splicing device for solderless splicing of a multi-lead cable such as a telephone cable to another cable or to outside wiring, said device comprising a channel-shaped cable retaining member having an open top and having an end portion sized to receive and retain the end portion of a cable in mounted position therein, said cable retaining member having a narrow groove extending along at least one side thereof and plurality of spaced transverse slots extending perpendicularly across said groove, each of said slots being sized to receive therein an inserted lead of the cable mounted in said cable retaining member, said device also comprising a top member of insulating material mounting a pluralitY of spaced incisive connectors, arranged in at least one longitudinal row, each of said connectors having a forked depending leg defining a central cutting slot therein, said legs being so spaced from each other that the distance between cutting slots in adjacent legs in said longitudinal row is equal to the distance between the spaced transverse slots in said cable retaining member, said top member being sized for insertion in aligned mounted position upon said cable retaining member to cover over the open top thereof, said row of incisive connectors being positioned on said top member such that the depending legs of said connectors enter the narrow groove of said cable retaining member when the top member is inserted in mounted position thereon.
Claim 2
Dependent Claim
237 words
A splicing device for solderless splicing of a multi-lead cable such as a telephone cable to another cable or to outside wiring, said device comprising a channel-shaped cable retaining member having an open top and having an end portion sized to receive and retain the end portion of a cable in mounted position therein, said cable retaining member having a narrow groove extending along at least one side thereof and plurality of spaced transverse slots extending perpendicularly across said groove, each of said slots being sized to receive therein an inserted lead of the cable mounted in said cable retaining member, said device also comprising a top member of insulating material mounting a pluralitY of spaced incisive connectors, arranged in at least one longitudinal row, each of said connectors having a forked depending leg defining a central cutting slot therein, said legs being so spaced from each other that the distance between cutting slots in adjacent legs in said longitudinal row is equal to the distance between the spaced transverse slots in said cable retaining member, said top member being sized for insertion in aligned mounted position upon said cable retaining member to cover over the open top thereof, said row of incisive connectors being positioned on said top member such that the depending legs of said connectors enter the narrow groove of said cable retaining member when the top member is inserted in mounted position thereon.
Claim 3
Dependent Claim
202 words
A splicing device according to claim 1 in which said cable retaining member has an elongated integral body portion having a central longitudinal groove extending the length thereof, said groove being sized to receive and mount a cable end portion at each end thereof, said body portion also having a pair of narrow grooves extending along the respective sides thereof and bordering said central longitudinal groove, and a plurality of spaced transverse slots extending across each of said narrow grooves, with the transverse slots at one side of said cable retaining member adapted to receive the inserted leads of one of said mounted cables and the transverse slots at the other side of said cable being adapted to receive the inserted leads of the other of said mounted cables, each of the incisive connectors on said top member being U-shaped and having a pair of interconnected, spaced depending legs, the legs of each said pair being spaced apart by a distance equal to the spacing between said narrow grooves, whereby when said top member is inserted in mounted position, one leg of each pair will enter one narrow groove and the other leg of each pair will enter the opposite narrow groove.
Claim 4
Dependent Claim
34 words
A splicing device according to claim 2 in which each of said incisive connectors has a plurality of attachment lugs sized to be attached to said top member for mounting said incisive connector thereon.
Claim 5
Dependent Claim
48 words
A splicing device according to claim 2 in which the distance between the pair of depending legs of each incisive connector is such that in said mounted position of the top member a surface of each leg bears snugly against an internal surface of the corresponding narrow groove.
Claim 6
Dependent Claim
67 words
A splicing device according to claim 1 in which said cable retaining member comprises two identical half-sections sized and shaped to be assembled in interfitting position in which they form the completed cable retaining member, each of the half-sections having locking means positioned to interengage in the assembled position of said half-sections to lock the latter against relative movement in the longitudinal direction of the mounted cable.
Claim 7
Dependent Claim
