Electrical connector having enhanced retention of contacts in a housing

摘要

An electrical connector comprises an insulative housing (20) and a plurality of first and second-type contacts (40, 50) received in the housing. The housing forms a pair of elongate ledges (23) running lengthwise along a bottom face (21) thereof. A plurality of pockets (231) is transversely defined through each ledge. A plurality of first and second passageways (25, 27) is defined through the bottom face of the housing for respectively receiving the first and the second-type contacts. Each second-type contact is of a conventional press-fit design. Each first-type contact includes a compliant pin at a lower end for being attached into a PCB and a mating portion at an upper end for electrically connecting with a mating contact of a mating connector, with a pair of supporting shoulders projecting from the upper end of the compliant pin for being retained in a corresponding pocket of a ledge. This arrangement enhances the support of and the retention force provided to the first-type contacts in the housing during the insertion of the compliant pins of the contacts into the PCB.
