Abstract
Abstract A tool connects plugs to the ends of communication wires and in particular is used with modular type communication plugs. The tool includes two relatively pivoted handle members that are restrained in the amount that they can be separated and which include a punch that will positively force connector tangs of a plug positioned in a provided receptacle in the tool into the ends of wires of a communication cord to properly and positively connect the individual wires of the cord to the proper terminal of the plug as the handles are squeezed. The tool also has knives which can be used for stripping a specified length from the end of the outer sheath from the insulated wires before inserting the wires into a plug carried in a close fitting receptacle in one of the handle members. The punch has separated lands or bars that separately bear against each contact tang of the plug and in this way force the connecting tang into the individual communication wires.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
366 words
A hand tool for connecting a communications plug to a communications cord having a plurality of conductors in such cord arranged in a known relationship, said tool comprising a pair of handle members pivotally mounted together adjacent one end thereof, and diverging so that the opposite ends of the handle members can be moved toward and away from each other, a first of the handle members having an integral mounting block portion between the pivot and the opposite end thereof, said block portion having a receptacle formed therein for receiving a communication plug and cord which are to be connected, said receptacle having a laterally facing plug receiving opening on one side of the block portion so a plug to be worked on may be inserted in direction generally parallel to the pivotal axis of handle members, said block portion further having a pair of passageways extending from a surface of the first handle member facing a second of the handle members and opening into the receptacle, said passageways being aligned with desired portions of a plug held in said receptacle and extending at substantially right angles to the direction of insertion of a plug into the receptacle, a pin slidably mounted in one of said passageways in said block, a punch slidably mounted in the other of said passageways in said block, said pin and punch each having a head member positioned on the exterior surface of the block on a side of the block facing the second handle member and adjacent the second handle member, means coupled to said pin and punch for causing movement thereof in direction away from said receptacle when the handle members separate including a spring for urging the pin and punch to move away from the receptacle and the handle members to separate, and an actuator lug mounted on the second of said handle members adapted to slidably engage and bear against both the head of the pin and the head of the punch, said handle members being movable toward each other to force the pin and the punch toward a plug held in the receptacle to engage members on the plug and connect the cord to the plug.

A hand tool for connecting a communications plug to a communications cord having a plurality of conductors in such cord arranged in a known relationship, said tool comprising a pair of handle members pivotally mounted together adjacent one end thereof, and diverging so that the opposite ends of the handle members can be moved toward and away from each other, a first of the handle members having an integral mounting block portion between the pivot and the opposite end thereof, said block portion having a receptacle formed therein for receiving a communication plug and cord which are to be connected, said receptacle having a laterally facing plug receiving opening on one side of the block portion so a plug to be worked on may be inserted in direction generally parallel to the pivotal axis of handle members, said block portion further having a pair of passageways extending from a surface of the first handle member facing a second of the handle members and opening into the receptacle, said passageways being aligned with desired portions of a plug held in said receptacle and extending at substantially right angles to the direction of insertion of a plug into the receptacle, a pin slidably mounted in one of said passageways in said block, a punch slidably mounted in the other of said passageways in said block, said pin and punch each having a head member positioned on the exterior surface of the block on a side of the block facing the second handle member and adjacent the second handle member, means coupled to said pin and punch for causing movement thereof in direction away from said receptacle when the handle members separate including a spring for urging the pin and punch to move away from the receptacle and the handle members to separate, and an actuator lug mounted on the second of said handle members adapted to slidably engage and bear against both the head of the pin and the head of the punch, said handle members being movable toward each other to force the pin and the punch toward a plug held in the receptacle to engage members on the plug and connect the cord to the plug.
Claim 3
Dependent Claim
44 words
The apparatus of claim 1 wherein said spring is a leaf spring having a first portion mounted on the hand tool and a second portion positioned under the heads of the pin and punch and urging the pin and punch away from the receptacle.
Claim 4
Dependent Claim
20 words
The apparatus of claim 1 and latch means to hold said handle members from separating more than a desired distance.
Claim 5
Dependent Claim
96 words
The apparatus of claim 3 wherein said latch means comprises a latch arm mounted on one of said handle members, and having a latch lip formed thereon, an aperture formed on the other of said handle members of size to receive said latch arm, one side surface defining the aperture being formed to provide a latch shoulder, said latch shoulder and latch lip engaging to prevent movement of said handle members more than a desired distance away from each, and said latch arm moving away from said latch surface when the handle members are moved together.
Claim 6
Dependent Claim
78 words
The apparatus of claim 1 wherein said mounting block of said first handle member has means to mount a cutting blade having an edge opening to and facing the second handle member, and means on said second handle member mounting a second cutting blade having an edge facing the first handle member, said first and second cutting blades cooperating to cut a cord used with a plug positioned between the blades as the handle members are pivoted together.
Claim 7
Dependent Claim
79 words
The apparatus of claim 5 wherein said mounting block member includes a channel formed adjacent the first blade having an end wall against which a cord can be abutted when the cord is positioned over said first mentioned blade, said handle members being adapted to be squeezed together so that the blade members cut a sheath on said cord without damaging the individual conductors of the cord to permit stripping the sheath from an end portion of the cord.
