IDC PIN FOR COMMUNICATION CABLE, WIRING CONNECTOR AND BLOCK, PARTICULARLY CONCERNED WITH REALIZING A FIRMER CONNECTION OF CABLE FOR COMMUNICATION CONNECTING, BY IMPROVING AN INSERTION HOLE OF A WIRING BLOCK WHERE AN IDC PIN IS INSERTED

摘要

PURPOSE: An IDC(Insulation Displacement Connector) pin for communication cable, a wiring connector and a block are provided to widen coupling grooves of an IDC pin to both sides with an elastic force like a torsion spring while enabling a 2-wire connecting operation, thereby more firmly maintaining the IDC pin within a wiring connector by a protruded part and hooking ends. CONSTITUTION: U-shaped coupling grooves(2) are cut in length direction toward a central portion from upper/lower parts of a length direction of an IDC pin(1), respectively. Upper grooves(2a) are isolated at certain intervals, while lower grooves(2b) are isolated at bigger intervals than the upper grooves(2a). Three sides except one side are cut in the right center of one side where certain ends of each lower groove(2b) are faced to each other, and are protruded outside, so that a cut side forms a protruded part(3) and hooking ends(4) protruded toward the other side of length direction on both sides of a boundary between the upper grooves(2a) and the lower grooves(2b).
