Patent ID: 8338705

Claim:
An electronic device comprising: a first housing; a grounding tab for attachment to the first housing, the grounding tab including an angled portion, an arcuate portion and an extending portion, the arcuate portion being connected between the angled portion and the extending portion, the arcuate portion defining a depression with an inside wall and a brim, a conductive layer coated on the inside wall of the depression; a second housing slidably attached to the first housing, and including two protrusions formed thereon, the angled portion and the extending portion of the grounding tab spaced from the second housing; wherein when the second housing is at a closed state relative to the first housing, one of the protrusions is received in the depression, and abuts against the conductive layer in the depression for electronically connecting the first housing to the second housing; when the second housing slides relative to the first housing from the closed state toward an open state, the brim of the arcuate portion of the grounding tab slides on the second housing and is spaced apart from the protrusions, preventing an electronic connection between the first housing and to the second housing; when the second housing slides to the open state relative to the first housing, the other of the protrusions is received in the depression, and abuts against the conductive layer in the depression for electronically connecting the first housing to the second housing.
