Abstract
Abstract An insulation displacement connector or terminal is comprised of inner and outer beams forming a slot. A coined area of the common portion between the inner and outer beams forces the inner beams toward each other and improves slot tolerance and spring force. The terminal may be provided with two slotted ends to permit the interconnection of different diameter cables or wires.

An insulation displacement terminal comprised of at least two outer beams and at least two inner beams forming a wire receiving slot, one each of said outer beams and said inner beams sharing a common portion having a coined area.
Claim 2
Dependent Claim
40 words
An insulation displacement terminal comprised of at least two outer beams and at least two inner beams forming a wire receiving slot, one each of said outer beams and said inner beams sharing a common portion having a coined area.
Claim 3
Dependent Claim
17 words
An insulation displacement terminal according to claim 1, wherein said common portion and coined area are slitted.
Claim 4
Dependent Claim
26 words
An insulation displacement terminal according to claim 1, wherein a section of said inner beams at an opening of said receiving slot has coined cutting edges.
