ABSTRACT:
An insulation displacement contact (IDC) includes a contact body and a pair of opposing blades extending from the body. The blades have edges spaced from and facing each other thereby defining a slot having a first width therebetween for receiving a wire. The edge of each blade forms an arcuate convex portion defining a gap of a second width therebetween. The second width is smaller than the first width thereby being capable of connecting with a wire of a smaller diameter. The convex portions of the blades may be formed by coining. A method for making the IDC contact is also disclosed. The method includes the steps of: (1) providing an IDC contact by punching or equivalent mechanical forming processes, the IDC contact having a contact body and a pair of opposing blades extending therefrom, the blades having edges facing and spaced from each other thereby defining a slot of a first width therebetween for receiving a wire, and (2) forming an arcuate convex portion on the edge of each blade by coining, the convex portions facing each other and defining a gap of a second width therebetween, the second width being smaller than the first width.
