Abstract

The retainer is composed of a single bent wire 10 constituting, in effect, a large spring. Retainer 10 snaps over stationary ears 12 on its ends and bears on electronic cards 14 holding them fixed with respect to connector board 16. Connector board 16 is provided with upstanding pins 18 which are received in corresponding recesses in electronic cards 14.

Electronic Card Retainer

The retainer is composed of a single bent wire 10 constituting, in effect, a large spring. Retainer 10 snaps over stationary ears 12 on its ends and bears on electronic cards 14 holding them fixed with respect to connector board 16. Connector board 16 is provided with upstanding pins 18 which are received in corresponding recesses in electronic cards 14.

The ends of retainer 10 are formed with loop portions 10a that extend around ears 12 and hold the retainer fixed with respect to ears 12 and connector board
16. The upper portion of retainer 10 is formed with oppositely extending undulations or legs 10b and 10c. Each of the legs 10b and 10c is provided with two dimples or concavities 10d and 10e which trap the cards 14 and prevent them from moving from side to side. Retainer 10 is also formed with a bow 10f looking at retainer 10 from the side. This is particularly apparent from the free condition of retainer 10 shown in dotted lines when no cards 14 are positioned between retainer 10 and connector board 16. The bow 10f ensures that cards 14 in the center of connector board 16 have sufficient retaining force applied to hold them in place on board 16.

Retainer 10 is, in effect, a large spring formed by a single wire of spring material and not only forcefully holds electronic cards 14 in place on connector board 16 but is so preformed with an initial length greater than the distance between ears 12 so that retainer 10 snaps onto ears 12 when forced over the ears and is fixed with respect to connector board 16. Retainer 10 may be co...
