Description

A kind of button and keyboard

Technical field

The present invention relates to button field, particularly relate to a kind of prevent keycap from coming off from key post button and keyboard.

Background technology

See Fig. 1, existing button comprises keycap 1a, guide pin bushing 2a, elastic supporting member for supporting optical member 3a and pedestal 4a, and wherein keycap 1a has support arm 11a, key post 12a and snap fit 13a, and snap fit 13a is formed at the free end of support arm 11a, and guide pin bushing 2a has keyhole 21a and holding section 22a; In time assembling, can first elastic supporting member for supporting optical member 3a be fixed on pedestal 4a, again guide pin bushing 2a is arranged on pedestal 4a, finally the key post 12a of keycap 1a is just inserted keyhole 21a to guide pin bushing 2a, because snap fit 13a has inclined-plane, when keycap 1a supports into guide pin bushing 2a along this first direction D1 ', the snap fit 13a of support arm 11a holds can to the Direction distortion close to key post 12a, thus make snap fit 13a can enter completely keyhole 21a and with holding section 22a; When user presses keycap 1a along this first direction D1 ', key post 12a can compress elastic supporting member for supporting optical member 3a and conductive film circuit layer on conducting pedestal 4a, and now, the conducting that can realize button controls; When user stops pressing keycap 1a, elastic supporting member for supporting optical member 3a can produce an elastic restoring force to compress key post 12a, thus make keycap 1a along the reverse motion returning to the front state of pressing of this first direction D1 ', when snap fit 13a abuts with the holding section 22a of guide pin bushing 2a, keycap 1a stops continuing the counter motion along this first direction D1 ' in keyhole 21a, and ensures that keycap 1a does not eject from keyhole 21.So this button snap fit 13a and holding section 22a coordinate the elastic restoring force that only can overcome elastic supporting member for supporting optical member 3a, keycap 1a is avoided to eject keyhole 21a under the effect of elastic restoring force, in actual use procedure, when having External Force Acting in keycap 1a and along this first direction D1 ' oppositely upper, keycap 1a is easy to extract from keyhole 21a, and causes keycap 1a to come off.

Therefore, a kind of novel button of design and keyboard is necessary, to overcome above-mentioned defect.
