Abstract

Apparatus is described which provides positive retention of a printed circuit card holder by mating sawtooth grid patterns on the holder and a stationary support. The printed circuit card 1 comprises a contact area 2 whereby electrical contact is made to the associated board (not shown). The card retention means comprising one support member 3 on each side of the card, and each support member has a spring lever 4 on the vertical end. The spring lever 4 has on its outside face a sawtooth grid pattern comprising a plurality of teeth 5 shaped as a right triangle with the acute angle as the leading edge. The card holder is guided into the board with the spring lever ends facing away from the board.

Positive Retention Card Holder

Apparatus is described which provides positive retention of a printed circuit card holder by mating sawtooth grid patterns on the holder and a stationary support. The printed circuit card 1 comprises a contact area 2 whereby electrical contact is made to the associated board (not shown). The card retention means comprising one support member 3 on each side of the card, and each support member has a spring lever 4 on the vertical end. The spring lever 4 has on its outside face a sawtooth grid pattern comprising a plurality of teeth 5 shaped as a right triangle with the acute angle as the leading edge. The card holder is guided into the board with the spring lever ends facing away from the board. As the card holder slides in, as it is fully positioned against the board, the spring levers 4 act as wedges when compressed inwardly. This results in an outward force on the sawtooth grid pattern. This sawtooth grid pattern structure meshes and automatically locks with a matching stationary grid patterned member (not shown). Only by compressing the spring lever ends 6, which serve as finger grips, and pulling can the circuit card be removed.
