Abstract

The present invention discloses a metallic linkage-type keying device, which is installed to a casing, such as the casing of a camera, a mobile phone or a video camera. The metallic linkage-type keying device of the present invention comprises: a metallic linkage, having at least two joining portions; and at least one key, having at least two assembling portions. The key is installed to the metallic linkage via fixing two assembling portions to two joining portions. The metallic linkage-type keying device provided by the present invention can prevent ESD from attacking the interior of the casing via key gaps and has the advantages of compactness and low cost.

Claims

1. A metallic linkage-type keying device, installed to a casing of an electronic device, and comprising:

a metallic linkage, having at least two joining portions; and

at least one key, having at least two assembling portions, and installed to said metallic linkage via engaging said two assembling portions to said two joining portions.

2. The metallic linkage-type keying device according to claim 1, wherein said electronic device is a camera, a mobile phone, or a video camera.

3. The metallic linkage-type keying device according to claim 1, wherein said joining portions are heat-fusion holes, and said assembling portions are heat-fusion protuberances;

said key is installed to said metallic linkage via heat-fusing said heat-fusion protuberances at said heat-fusion holes.

4. The metallic linkage-type keying device according to claim 1, wherein said key is made of a plastic material.

5. The metallic linkage-type keying device according to claim 1, wherein said metallic linkage further comprises a grounding portion, and electro static discharge is guided to the ground via said grounding portion of said metallic linkage.

6. The metallic linkage-type keying device according to claim 1, wherein said metallic linkage has at least two fixing portions, and said casing has at least two connecting portions disposed corresponding to said two fixing portions;

said metallic linkage is installed to said casing via engaging said two fixing portions to said two connecting portions.

7. The metallic linkage-type keying device according to claim 6, wherein said fixing portions are heat-fusion holes, and said connecting portions are heat-fusion protuberances;

said metallic linkage is installed to said casing via heat-fusing said heat-fusion protuberances at said heat-fusion holes.

8. The metallic linkage-type keying device according to claim 1, wherein said metallic linkage has multiple said joining portions, and said key has multiple said assembling portions;

said key is installed to said metallic linkage via engaging said assembling portions to said joining portions.
