Insulation-stripping electrical contact device

A device comprising:

• an insulating housing (20) having a receiving area with a contact receiving slot (21) extending across the receiving area, the receiving area being designed to receive a cable (3) with insulating covering (31) thereon, the cable being inserted into the receiving area along an insertion axis (.DELTA.');
• and
• an insulation stripping contact (1) positioned in the contact receiving slot (21), the contact having a first blade (11) and a second blade (10) joined to a common base to form a cable receiving slot (13) of a given width ("e") between the first and second blades, and the contact (1) being located in the contact receiving slot (21) of the insulating housing (20) such that, when the cable (3) is received in the receiving area of the housing, the cable (3) is inserted into the cable receiving slot (13) of the contact;
• wherein the contact receiving slot (21) comprises a first groove (200) and a second groove (201) formed in the opposing side walls of the receiving area of the housing, the first groove (200) being angled relative to the second groove (201) with the first groove (200) being orientated relative to the insertion axis (.DELTA.') at an angle of about 90.degree. and the second groove (201) forming an angle (.beta.) with the insertion axis (.DELTA.') greater than 0.degree. and less than 90.degree., and wherein the first blade (11) has a smaller width than the second blade (10) and the first blade (11) is located in the first groove (200) and the second blade (10) is located in the second groove (201) of the contact receiving slot (13) so that the first blade is angled relative to the second blade, the first groove being adapted to allow the first blade to translate therein without substantial rotation, the first blade butting a bottom of the first groove when the first blade is subjected to a force directed along an axis orthogonal to the axis of insertion (.DELTA.'), and wherein when the cable is inserted in the cable receiving slot the second blade is bent and pressed toward a first side wall of the second slot and the first and second blades cooperate to cut and wedge apart the insulation covering of the cable.
