Abstract
Abstract A system for providing cross connections for telephone subscriber lines to associate them with office line equipment within a telephone office. The system includes a plurality of jack boards mounted on telephone main frames, each defining a series of interconnection locations including a pair of projecting contacts and a socket adjacent to the contacts. Cooperating with each location is a plug assembly with corresponding projection and female contacts, the last mentioned contacts including means for displacing insulation on engaged conductors upon the closing together of two component parts comprising a housing. The use of usual wire wrapping techniques is completely eliminated, and the use of less skilled personnel in making the cross connections is possible.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
211 words
An improved wire plug assembly for use in interconnecting a telephone subscriber pair between corresponding connecter blocks comprising: first and second elongate interconnectable housing members, means at first and second ends of said housing members for the interconnection of said housing members to define plural communicating recesses therein; a pair of resilient contact members disposed in two parallel recesses of said plural recesses, said housing member defining end openings for the insertion of electrically conductive pins therethrough to engage said resilient contact members substantially at one end thereof; said contact members having wire insulation displacement means substantially at a second end thereof, at least one of said housing members defining end openings therein for the insertion of an insulated conductor to be positioned opposite the insulation displacement means of one of said contact members, said insulation displacement means engaging an end of said conductor upon the closing of said pair of housing members to assemble said plug assembly; said housing element having a resilient detent projection on an end thereof adjacent said openings for said conductive pins for the engagement of a corresponding opening in a jack board, and a handle member on an opposite end of said housing element to permit disengagement of said plug assembly from said jack board.
Claim 2
Dependent Claim

An improved wire plug assembly for use in interconnecting a telephone subscriber pair between corresponding connecter blocks comprising: first and second elongate interconnectable housing members, means at first and second ends of said housing members for the interconnection of said housing members to define plural communicating recesses therein; a pair of resilient contact members disposed in two parallel recesses of said plural recesses, said housing member defining end openings for the insertion of electrically conductive pins therethrough to engage said resilient contact members substantially at one end thereof; said contact members having wire insulation displacement means substantially at a second end thereof, at least one of said housing members defining end openings therein for the insertion of an insulated conductor to be positioned opposite the insulation displacement means of one of said contact members, said insulation displacement means engaging an end of said conductor upon the closing of said pair of housing members to assemble said plug assembly; said housing element having a resilient detent projection on an end thereof adjacent said openings for said conductive pins for the engagement of a corresponding opening in a jack board, and a handle member on an opposite end of said housing element to permit disengagement of said plug assembly from said jack board.
Claim 3
Dependent Claim
33 words
An improved wire plug assembly in accordance with claim 1, one of said housing members having openings therein permitting the viewing of the end of inserted conductors to assist in the positioning thereof.
Claim 4
Dependent Claim
47 words
An improved wire plug assembly in accordance with claim 1, in combination with a corresponding jack board defining at least one area having projecting pins and a through recess adjacent said pins, said pins penetrating said opening in said housing, said recess accomodating said resilient detent projection.
