An insulation displacement connector (IDC) includes a pair of spaced, coextensive U-shaped beams fixed to each other along one pair of the beam portions of the beams in a mounting plane, the other pair of beam portions being free to move away from each in a contact plane in response to a wire and its insulation being forced into a wire-receiving channel or groove formed between the U-shaped beams. The IDC can be provided with mounting legs for mounting on a PC board, or on the body of a connector terminal. By curving at least one of the portions of the U-shaped beams a preset can be imparted to the contact of the IDC. The contacts can be shaped to receive a curve or cable, an electrical tab, a fuse or the like. When the IDC is used to terminate a wire or cable, it is preferably provided with a strain relief slot to minimize axial or longitudinaly forces of the wire or cable at the points where the insulation is displaced and electrical contact is made with the IDC. In use, separation of the contact beam portions creates torsional stresses in the IDC which act to secure the electrical component between the contact beam portions in an effective and reliable manner.
An insulation displacement connector for attachment to an insulation covered wire comprising a pair of substantially co-extensive U-shaped beams formed of flat sheet material and laterally spaced from each other to form a longitudinal wire-receiving channel, each U-shaped beam having substantially parallel contact portions and mounting beam portions and a transverse beam portion extending between and joining said mounting and contact beam portions, said mounting beam portions of said U-shaped beams being rigidly fixed to each other in a mounting plane to prevent relative movements which separate said mounting beam portions in said mounting plane, said contact beam portions of said U-shaped beams being arranged a predetermined distance from each other in a contact plane which is substantially parallel to said mounting plane, said contact beam portions being movable within said contact plane to separate said contact beam portions when a wire is placed into said wire-receiving channel, at least portions of said transverse beams being torsionally deformable when a wire is placed within said wire-receiving channel and said contact beam portions are forced by the wire and its insulation to separate and thereby increase the spacing between said contact beam portions within said contact plane beyond said predetermined distance.
