Abstract
Abstract A wire connecting system which includes a pair of mating connectors for effecting electrical cross connections between a first set of of conductors and a second set of conductors is presented. The two mating connectors are known by the terms "wiring block" and "connecting block" wherein the wiring block provides evenly spaced receptacles for the first wire conductors that hold them in alignment for engagement with a plurality of insulation penetrating slotted beam contacts carried by the connecting block. The plurality of insulation penetrating slotted beam contacts housed by the connecting block are double ended such that, once the first set of wire conudctors are terminated, a second set of wire conductors are then indexed and retained by the connecting block for subsequent termination to the opposing ends of the insulation penetrating contacts by a tool or end cap designed for such a purpose. The connecting block employs a novel one piece structure which both forms the connector block housing as well as provides retention means for positioning and retaining the slotted beam contacts. These retention means comprise retention posts which are flash molded onto the side of the connecting block during the molding operation. Upon insertion and positioning of a plurality of beam contacts within the connecting block housing, pressure is exerted against the retention posts thereby breaking the flash molding and forcing the posts through positioning holes in the contacts. Thereafter, the post tips are peened in place providing permenant but free floating connection between the contacts and the connecting block housing. Still another important feature of the present invention is the novel use of a "zero gap" insulation displacement connector in the slotted beam contact.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
160 words
A connecting block for housing a plurality of insulation penetrating beam contacts, comprising: a housing having first and second spaced apart sidewalls and opposed upper and lower ends; a plurality of spaced apart insulation penetrating beam contacts in said housing extending between said upper and lower ends, each of said contacts having a first aperture therethrough; a plurality of spaced openings through said second sidewalls of said housing, one each of said openings being aligned with one each of said apertures in said beam contacts; and a plurality of spaced contact retention posts integrally molded to said first sidewall of said housing and extending laterally from said first sidewall, one each of said posts being mutually aligned with one each of said openings and one each of said apertures wherein said posts are forced under pressure to break away from said first sidewalls and are positioned through said apertures and openings to thereby retain said beam contacts within said housing.
Claim 2
Dependent Claim
160 words
A connecting block for housing a plurality of insulation penetrating beam contacts, comprising: a housing having first and second spaced apart sidewalls and opposed upper and lower ends; a plurality of spaced apart insulation penetrating beam contacts in said housing extending between said upper and lower ends, each of said contacts having a first aperture therethrough; a plurality of spaced openings through said second sidewalls of said housing, one each of said openings being aligned with one each of said apertures in said beam contacts; and a plurality of spaced contact retention posts integrally molded to said first sidewall of said housing and extending laterally from said first sidewall, one each of said posts being mutually aligned with one each of said openings and one each of said apertures wherein said posts are forced under pressure to break away from said first sidewalls and are positioned through said apertures and openings to thereby retain said beam contacts within said housing.
