Detailed Description

In order to facilitate the understanding of those skilled in the art, the present invention will be further described with reference to the following examples and accompanying fig. 1-4, which are not intended to limit the present invention.

The utility model provides a pearly-lustre cell-phone side button, includes the button body and cup joints 5, the button body includes key cap 1 and sets up in joint spare 2 of 1 lower extreme of key cap, the protruding round spacing collar 4 that is equipped with of upper end to the periphery of key cap 1, the outside protruding card foot 3 that is equipped with of lower extreme of joint spare 2, cup joint 5 cup joint spare 2 and with card foot 3 forms the joint structure, the lower extreme that cup joints 5 is provided with a plurality of contact pressure feet 6 that are used for touching with FPC, the surface complex of key cap 1 has pearly-lustre lacquer layer 7.

The utility model discloses a side button simple structure can be established key cap 1 card on the key hole through the spacing collar 4 that key cap 1 protruding was established, avoids it to excessively get into in the key hole, further cover in joint spare 2 of key cap 1 lower extreme establishes cup joint piece 5, cup joint piece 5 adopts comparatively soft material, for example TPU, the side button of being convenient for gets into the key hole from outside to inside and accomplishes the installation, the pressure of touching FPC is pressed in the touch foot 6 of cup joint piece 5 buffering also better, avoids crushing FPC; in addition the utility model discloses can give 1 pearly-lustre effect of key cap at 1 compound pearly-lustre lacquer layer 7 of key cap surface, richen key cap 1's outward appearance variety.

The button body is a PC (personal computer) button, and the sleeving piece 5 is a TPU (thermoplastic polyurethane) plastic piece.
