Multi-contact electrical connector

A multi-contact electrical connector for connecting a plurality of insulation clad wires to a circuit means, the electrical connector comprising:

• a plurality of electrical contact means adapted to be respectively connected to the insulation clad wires, each of the electrical contact means are fashioned as a stamped one piece sheet metal member bent into a predetermined shape and includes a substantially box shaped contact body and a pair of spaced pressing means provided with opposed side ridges, with the space between the pressing means being less than a diameter of a conductor in the wires whereby the insulation cladding of the wires is penetrated by the side ridges to enable a contact between the electrical contact means and the conductor, said pressing means being formed by opposed side walls of said contact body;
• a housing means including a plurality of chamber means for respectively accommodating the electrical contact means, means for holding the respective wires in the housing means, and means adapted to receive electrical terminal means connected to the circuit means, the means for receiving being arranged in a lower portion of the respective chamber means and extending substantially parallel to the means for holding the respective wires;
• and
• means provided on each of said electrical contact means for establishing a detachable electrical connection between the electrical contact means and the terminal means including an extension portion provided on at least two opposed side walls of said contact body, said extension portions terminating in rolled ends so as to impart a biasing force thereto.
