ABSTRACT:
An electrical connector for mating with a terminal assembly to complete an electrical connection with an insulation displacement terminal of the terminal assembly is disclosed. The connector comprises a dielectric housing having a latch for releasably latching the connector in a predetermined position on the terminal assembly and a male electrical contact member carried on the housing for insertion into the insulation displacement terminal. The electrical contact member has an inclined lateral surface for intimately contacting a surface of the insulation displacement terminal over an extended area when the housing is latched in its predetermined position on the terminal assembly. The extended area of contact is more resistant to wear and less vulnerable to oxidation than a point or line contact would be, particularly over repeated matings and unmatings of the connector with the terminal assembly. The contact member is coated with a layer of selenium bright tin overplate, to provide wear resistance, over a layer of nickel underplate, to provide surface malleability which permits the contact surface to conform somewhat to the insulation displacement terminal. The connector is useful for patch cords and the like for distribution frames in telephone exchanges.
