ABSTRACT:
A card edge connector (10) includes electrical contacts (15) for engaging traces of a printed circuit card to establish electrical connection therewith, a housing (16) for supporting the contacts, a strain relief (17) directly molded to at least part of the contacts and housing for securing the same as an integral structure, the contacts having a compliance characteristic in the card edge connector, and a secondary compliance mechanism (95) for increasing the effective compliance characteristic of the contacts in the card edge connector. Such secondary compliance mechanism is provided by a shrinkage of some of the molded strain relief material during cooling thereof. The contacts and housing provide part of a shut of function and a shut off key (56) inserted into the housing for use during the molding provides another part of a shut off function to block flow of molding material into a contacting area of the housing (27). The invention also relates to a method for making a card edge connector and a machine for making a card edge connector.
