ABSTRACT:
A sealed ZIF connector for mating to a complementary connector with an internal PCB is for use with non-gold-plated terminals for a cost effective design. Such a connector may be for use in an automobile, for connection to a motor management electronics module. The connector is provided with a pivotable camming member having an oval camming surface positioned between contact arms of the terminals. In the pre-mated condition the camming surface spreads the terminal contact arms apart and the connectors can be coupled until the end of the PCB is almost against the camming surface. Upon rotation of the camming mechanism, the cam releases the contacts which bias against the PCB, whereby the cam subsequently abuts the end of the PCB to slightly separate the connectors. Separation of the connectors causes a wiping action between the contacts and the PCB to clean the surfaces from oxidation layers. The latter thus allows use of tin plated contacts for ZIF connectors.
