ABSTRACT:
This invention is directed too a PCMCIA frame kit having improved stability, where the kit is intended to receive a planar electronic device for electrical engagement with a complementary device in electronic equipment. The kit comprises a pair of matable, metal cover members, where each cover member is integrally molded to a dielectric frame upon which the planar electronic device is seated. The improved feature is the provision of each frame including at least a pair of side rails, where at least one side rail pair on one cover member includes plural, circular, upstanding pins having a predetermined diameter, the matable side rail on the other cover member includes a like plurality of holes to receive a corresponding pin. In a preferred embodiment, the cross section of holes exhibits a multi-sided configuration with the diametrical distance between opposing corners being slightly greater than the predetermined diameter, and the diametrical distance between opposing sides in slightly less than the predetermined diameter. By this arrangement a normal force applied between the covers effects a force fit between each respective pin and its multi-sided hole.
