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.

Claims

1. In a PCMCIA frame kit for receiving a planar electronic device for electrical engagement with a complementary device in electronic equipment, said kit comprising a pair of matable, metal cover members, where each said cover member is integrally molded to a dielectric frame upon which said planar electronic device is seated, the improvement comprising in combination therewith the provision of each said frame including at least a pair of side rails, where said pair of side rails on one cover member includes plural, circular, upstanding pins having a predetermined diameter, and said pair of side rails on the other cover member including a like plurality of holes, where the cross section of said holes exhibits a multi-sided configuration with the diametrical distance between opposing corners being slightly greater than said predetermined diameter, and the diametrical distance between opposing said sides is slightly less than said predetermined diameter, whereby a normal force applied between said covers effects a force fit between each respective pin and its multi-sided hole.

2. The PCMCIA frame kit according to claim 1, wherein said multi-sided configuration is a hexagon.

3. The PCMCIA frame kit according to claim 1, wherein one pair of said side rails includes a narrow groove along a mating surface thereof.

4. The PCMCIA frame kit according to claim 3, wherein said side rails of the other cover member includes a complementary narrow rib engagable with said corresponding groove.

5. The PCMCIA frame kit according to claim 4, wherein through the engagement of respective grooves and ribs said engagement offers improved stability to the assembled frame kit.

6. The PCMCIA frame kit according to claim 1, wherein said frame kit is generally rectangular in shape, and that said cover members include side rails along three sides, with the fourth side open to expose said planar electronic device for mating with an electrical connector.

7. The PCMCIA frame kit according to claim 1, wherein the assembled frame kit maybe subjected to localized sonic welding to effect a weld between said engaged pin and its respective said hole.

8. The PCMCIA frame kit according to claim 1, wherein a free end of each said circular pin is tapered to facilitate entry into a respective said multi-sided hole.

9. The PCMCIA frame kit according to claim 1, wherein a plurality of ribs are provided about the side of the peripheral frame of one cover member, and the other cover member includes a like plurality of notches, where a snap engagement of said cover members is achieved through mating of each ribs to its respective notch.

10. The PCMCIA frame kit according to claim 9, wherein sonic welding may be applied to each mated ribs and notch to further stabilize the assembled frame kit.

11. In a PCMCIA frame kit for receiving a planar electronic device for electrical engagement with a complementary device in electronic equipment, said kit comprising a pair of matable, metal cover members, where each said cover member is integrally molded to a dielectric frame upon which said planar electronic device is seated, the improvement comprising in combination therewith the provision of each said integral cover member and dielectric being essentially identical to one another, and that each said frame includes a first and second side rail, where said first side rail includes a plural, circular, upstanding pins having a predetermined diameter, and said second side rail includes a like plurality of holes, where the cross section of said holes exhibit a multi-sided configuration with the diametrical distance between opposing corners being slightly greater than said predetermined diameter, and the diametrical distance between opposing said sides is slightly less than said predetermined diameter, whereby a normal force applied between said covers effects a force fit between the respective pins of said first side rail and the multi-side hole of the second side rail of the other cover member.

12. The PCMCIA frame kit according to claim 11, wherein said multi-sided configuration is a hexagon.

13. The PCMCIA frame kit according to claim 11, wherein one pair of said side rails includes a narrow groove along a mating surface thereof.

14. The PCMCIA frame kit according to claim 13, wherein said side rails of the other cover member includes a complementary narrow rib engagable with said corresponding groove.

15. The PCMCIA frame kit according to claim 14, wherein through the engagement of respective grooves and ribs said engagement offers improved stability to the assembled frame kit.

16. The PCMCIA frame kit according to claim 11, wherein said frame kit is generally rectangular in shape, and that said cover members include side rails along three sides, with the fourth side open to expose said planar electronic device for mating with an electrical connector.

17. The PCMCIA frame kit according to claim 11, wherein the assembled frame kit may be subjected to localized sonic welding to effect a weld between said engaged pin and its respective said hole.

18. The PCMCIA frame kit according to claim 11, wherein a free end of each said circular pin in tapered to facilitate entry into a respective said multi-sided hole.

19. The PCMCIA frame kit according to claim 11, wherein a plurality of ribs are provided about the side of the peripheral frame of one cover member, and the other cover member includes a like plurality of notches, where a snap engagement of said cover members is achieved through mating of each ribs to its respective notch.

20. The PCMCIA frame kit according to claim 19, wherein sonic welding may be applied to each mated ribs and notch to further stabilize the assembled frame kit.
