Abstract

An apparatus for mounting a printed circuit board in a monitor case including a frame and a plurality of resilient members cooperating therewith to removably fasten the printed circuit board onto the frame. The printed circuit board includes apertures adapted to receive an engaging member integrally provided on the frame to locate and align the printed circuit board. The resilient members comprise upper portions having resiliently biased elements which secure the engaging member of the frame, and lower portions having affixing tabs adapted to be received in apertures formed in the printed circuit board. The frame also includes a support brace to fully support the printed circuit board to prevent sagging and deformation. The printed circuit board is removably retained on the frame by cooperation of the engaging member and resilient elements such that assembly and disassembly is facilitated thereby saving time and enhancing production yield.

Claims

1. A printed circuit board fixing apparatus for affixing a printed circuit board onto which a variety of electronic components are mounted within a monitor case and shielding the printed circuit board from electromagnetic waves, the printed circuit board having a thin copper film surface on a first side thereof, an engaging slot and an insertion aperture adjacent the slot, said printed circuit board fixing apparatus comprising:

a frame including at least two opposing side walls, each of said side walls having a protrusion for supporting the printed circuit board with the film surface disposed upward;

a shield plate attached to the bottom of said frame and including an integral engaging pin extending upward to be received in the engaging slot of the printed circuit board; and

a resilient clip including a contact device and an affixing tab receivable in the insertion aperture for securing the printed circuit board to said frame, said contact device adapted to contact said engaging pin to provide contact between said shield plate and the printed circuit board through said engaging pin.

2. The fixing apparatus of claim 1, wherein said contact device of said resilient clip comprises a pair of opposed elastic members disposed above said affixing tab, said elastic member biased toward one another and converging to contact said engaging pin therebetween.

3. The fixing apparatus of claim 2, wherein said engaging pin is a flat key member.

4. The fixing apparatus of claim 1, wherein said resilient clip is tubular above said affixing tab and said contact device comprises inwardly biased convexly concave elastic tabs which converge toward one another at a contact point to contact said engaging pin therebetween.

5. The fixing apparatus of claim 4, wherein said engaging pin is a cylindrical member.

6. The fixing apparatus of claim 1, wherein said frame further comprises a locking tab provided on each said side wall for securely locking the printed circuit board onto said frame, said locking tabs aligned with said protrusions to trap the printed circuit board therebetween.

7. The fixing apparatus of claim 1, further wherein said frame further comprises a brace extending along the bottom of said frame to reinforce said frame and further support the printed circuit board.

8. A support assembly for supporting a printed circuit board having at least two mounting apertures adjacent one another, said support assembly comprising:

a frame for supporting the printed circuit board;

a shield plate attached to said frame, said shield plate comprising an engaging pin received in one of said mounting apertures of the printed circuit board;

a securing member including an affixing tab received in the other one of said mounting apertures of the printed circuit board and a contact device for contacting said engaging pin to provide electrical conductive contact between the printed circuit board and said shield plate to thereby ground the printed circuit board.

9. The support assembly of claim 8, wherein said contact device of said securing member comprises a pair of opposed elastic members disposed above said affixing tab, said elastic members biased toward one another and converging to contact said engaging pin therebetween.

10. The support assembly of claim 9, wherein said engaging pin is a flat key member.

11. The support assembly of claim 8, wherein said contact device comprises inwardly biased strips formed on opposing walls of said securing member, said strips converging toward one another at a contact point to contact said engaging pin therebetween.

12. The support assembly of claim 11, wherein said engaging pin is a cylindrical member.

13. The support assembly of claim 8, wherein said frame further comprises opposing frame side walls and a pair of vertically aligned locking protrusions provided on each of said side walls for securely locking the printed circuit board into said frame.

14. The support assembly of claim 8, wherein said frame further comprises a ribbed member extending a length therealong to support the printed circuit board.
