Abstract
A sheet metal cover (11) for a PC card, or electronic card, includes identical top and bottom sheet metal cover parts (13, 12) with opposite sides constructed to allow the cover parts to be joined together by merely pushing the sides of the top cover part forcefully down against the sides of the bottom cover part. One side (23) of each cover part is bent and cut to form a plurality of latching lugs (37), and the other side (24) of each cover part is bent and cut to form a plurality of slots leading to recesses that each receives a lug and then resists movement of the lug out of the recess. Each lug has outer and inner legs (38, 39) that are joined in a fold of less than 90°. The slots each receives a lug only when the inner and outer legs of the lug are deflected closer together.
Claims14
An electronic card of the type that has a circuit board and a sheet metal cover that surrounds a majority of the circuit board, wherein the cover includes top and bottom sheet metal cover parts with primarily horizontal bases that each lies primarily in a horizontal plane, said cover parts each having longitudinally-spaced opposite ends and laterally spaced opposite sides, each of said cover parts having a lateral middle lying inward of said sides, and said sides lying outward of said middle, said top and bottom cover parts having respective top and bottom first side walls that are joined together, wherein:
- said top first side wall forms a plurality of longitudinally-spaced latching lugs;
- said bottom first side wall forms a plurality of longitudinally-spaced lug-receiving recesses that each receives a lug when the lug is moved down into the recesses, and that each engages the lug to resist upward movement of the lug out of the recess.
An electronic card of the type that has a circuit board and a sheet metal cover that surrounds a majority of the circuit board, wherein the cover includes top and bottom sheet metal cover parts each with a base that lies primarily in a horizontal plane and that has laterally opposite base side regions, each of said cover parts having a lateral middle lying inward of said side regions, laterally-spaced largely vertical opposite sides and longitudinally-spaced opposite ends, said sides including top and bottom first sides of said top and bottom cover parts, respectively, that are joined together, wherein:
- said top first side forms a plurality of longitudinally-spaced latching lugs;
- said bottom first side forms means for engaging said lugs and resisting their upward movement after said top first side is moved down against said bottom first side.
An electronic card of the type that has a circuit board and a sheet metal cover that surrounds a majority of the circuit board, wherein the cover includes top and bottom sheet metal cover parts with bases that each lies primarily in a horizontal plane and has laterally opposite sides, each of said cover parts having a lateral middle lying inward of said major sides, laterally-spaced largely vertical opposite side walls and longitudinally-spaced opposite ends, wherein:
- said top and bottom cover parts are substantially identical;
- a first side of each cover part has a plurality of longitudinally-spaced lugs, each lug having a pair of legs and a fold that joins them,
- said largely vertical side wall of a second side of each cover part includes an inwardly-extending horizontal second middle slot wall that is vertically spaced from the base of the same cover part, said slot wall having a plurality of slots, each slot having a width chosen to receive one of said lugs only by deflecting the legs of the lug closer together.
