The base comprises grooves separated by longitudinal bosses and the cover is equipped with grooves separated by longitudinal ribs to house wires of an electrical cable. The cover in addition bears, in recesses arranged in the grooves, connecting grips arranged to perform electrical coupling by perforation of the self-baring type of the insulator surrounding the conductor of the wire.

Abstract: An insulation displacement connecting (IDC) terminal that allows wires to be parked in a retaining region thereof prior to being terminated within and IDC portion of the terminal. The retaining region of the terminal is generally a rounded longitudinal slot having a width which is slightly less than the outermost diameter of a conductor to be inserted into the terminal. The terminal which is designed with large fiat spring contacts located about a central slot, includes an IDC portion, which cuts into the insulation of the wire to establish contact. A slight gap in a top portion of the retaining region pulls apart and allows for insertion of a wire into the slot of the retaining region. The spring contacts of the terminal pull together and the gap is narrowed once the wire enters the retaining region, thus, preventing the wire from escaping through the gap. The spring contacts then close on the wire where it remains parked until such time as the wire is terminated within the IDC portion of the terminal.

Abstract: A printed circuit board mountable connecting block of the type described in U.S. Pat.

The connecting block of this invention may be mounted directly onto (e.g., through) a printed circuit board (or other electronic component). It will be appreciated that this circuit mountable feature is required and advantageous for many applications. In addition, the use of a solderless connector means (preferably a press-fit tail) is particularly advantageous for providing ease of assembly as well as lower cost (relative to conventional solderable tails).

Abstract: An insulation displacement connecting (IDC) terminal that accepts two insulated wires in a single slot for the making of an electrical connection. The IDC portion of the terminal, which cuts into the insulation of the wire to establish contact, is designed with large flat spring contacts about a centrally located slot, wherein the contacts displace torsionally when normal forces placed on the terminals exceed a fixed load. The torsional displacement is enabled by the inclusion of a widened slot proximate a base portion of the terminal. The widened slot in combination with an angular orientation of the terminal contained within an insulated connector module housing enables the contacts to twist to away from one another. This displacement effect allows for larger gauge and more than one conductor to be inserted into the terminal without permanently yielding the beam contacts of the terminal.

Abstract: An improved barrel-shaped IDC contact comprises a cylindrical body section having a longitudinal IDC slot formed by opposed edges. Extending longitudinally alongside the edges are cutouts forming a resilient beam section therebetween in order to increase the resiliency of the IDC slot.
