ELECTRICAL CONNECTOR HAVING PRESS-FIT CONTACTS FOR CIRCUIT BOARD MOUNTING

摘要

An electrical connector (20) having a housing block (24) with a plurality of passageways (50) into which are inserted respective contact terminals (34). The passageways and the contact terminals are so designed that the contact terminals are press-fit into the passageways and displace dielectric material of the housing block to provide a "seal" which prevents solder flux from wicking up the passageways. In addition, the contact terminals are formed with a longitudinal knurl (38) to prevent rotation of the contact terminals after insertion. Still further, each contact terminal is formed with a frusto-conical retention collar (42) having a rearward facing surface (66) which, upon exiting a passageway, abuts against a recessed stop ledge (64) formed in the housing block to prevent the subsequent removal of the contact terminal from the housing block.
