Abstract

Female terminal connectors, suitable for receiving a pin having a square or rectangular cross-section are generally provided with tin or gold contacts. Depending upon the specific application. tin or gold contacts are selected for reasons of cost and durability. Generally, the tin contacts are less expensive, while the gold contacts provide a more durable contact surface. Furthermore, the connectors are intended for use with mating pieces having a similar contact metal. For example, a female terminal with gold contacts is intended to be mated with a male pin having a gold plated outer surface. The use of similar metals is required to reduce the potential for galvanic corrosion of the contact region.
