Card Connector

Planar resilient tabs end an orthogonally oriented resilient projection are integrally formed in the planar stem of the conductor members of a printed circuit (PC) card or board edge connector.

For example, card edge connector 10 is of the type that has two rows of multiple pairs of spring contact members 11 and 12 which are mounted in openings 14 and 15 of phenolic insulator member 13. The contact members 11 and 12 are in alignment and registration with the lower and upper PC contact pads L and U located on opposite surfaces of the planar PC card and make contact with the pads when the card is fully inserted along its insert edge E between the two constituent members of paired members 11 and 12, cf. arrow A.

Each member has four resilient tabs 16 and an orthogonally oriented bridge- like resilient portion 17, cf. enlargements of Figs. 2 and 3, located on the portion of the particular member's stem which is within the opening 14 or 15, as the case might be. This facilitates the press fit assembly of members 11 and 12 into the openings 14 and 15. In addition, the tabs 16 and projection 17 causes the members 11, 12 to be securely mounted in the respective openings 14, 15 by virtue of the clamping action they provide against the walls of the openings 14,
15.

During manufacture of the members 11 and 12, the planar tabs 16 are stamped out of the stock with the stems. The center of the stem at the site where the bridge projection 17 is to be formed is co...
