ABSTRACT OF THE DISCLOSURE This invention relates to electrical connectors of the insulation-opening type and, more particularly, to electrical connec- tors having contacts with flexible sidewalls which hold the contacts in the cavities of the connectors. The contacts generally include terminal elements which sever the insulation and establish an elec- trical connection with the conductor without the need for any stripping or soldering operation. Since the insulation-piercing contacts may be most economically manufactured by stamping operations, It is necessary to use sheet metal stock which is easily formable. Accordingly, the insulation-piercing terminal elements of prior art contacts may be deformed in the connecting operation to the point where proper elec- trical connection is adversely affected. Additionally, prior art insul- ation-piercing connectors are not well suited to stranded core conduc- tors. According to the present invention, at least one of the side- walls includes a portion which Is displaceable from an initial, pre- assembly position wherein the transverse dimension of the contact Is greater than the transverse dimension of the cavity, to a final, assembled position wherein the sidewalls are located within and en- gage the lateral surfaces of the cavity. In addition, the contact includes at least one pair of protuberances which form a conductor- receiving notch adapted to open or displace the insulation and make electrical connection with the conductor. The various structural components of the contact are dimensioned relative to each other and the conductor being terminated to minimize the changes in termination resistance which typically occur when stranded core conductors are terminated with conventional contacts.
