ABSTRACT:
A connector which has bellows type contacts of spring metal and a holder which has a bottom, a longitudinal slot for receiving a circuit panel, a cavity for housing the bellows type contact, a hollow formed at upper portion of the cavity and partition wall for separating the adjacent contacts. The bellows type contact consists of a lower end portion, an attached portion, a first bent portion, a second bent portion, a straight portion, a third bent portion and an upper end portion. The straight portion is the portion contacting the panel circuit. The contact has a spring substrate which consists of phosphor bronze, a contact metal of tin or tin-lead alloy, and a layer of copper between the substrate and the contact metal. With the improved shape and material of the contact, there is provided better contact performance even for a contact of tin or tin-lead alloy which is very cheap compared to the conventional gold contact and it is thus advantageous for use in consumer type electric equipment.
