Cam actuated zero insertion force mother/daughter board connector

摘要

A zero insertion force connector is disclosed for making an interconnection between a mother circuit board and a daughter circuit board. A receptacle assembly is mounted on the mother board and includes a housing with a carrier block movably mounted therein. A plurality of first terminals are fixed in the housing and a plurality of second terminals are fixed in the carrier block making a constant wiping engagement with the first terminals. In a two-piece embodiment a plug assembly is mounted on the daughter board and is receivable in the cavity of the receptacle assembly. A plurality of third terminals are mounted on the plug assembly and make a fixed engagement with the daughter board and are positioned to make a wiping engagement with the second terminals in the carrier block after the plug assembly is received in the receptacle assembly and the carrier block is moved relative thereto. In a one-piece or edge board embodiment, the second terminals have folded beams which, when raised by the carrier block, engage the receptacle housing to be cammed into wiping contact with the daughter board.
