The connecting clip is symmetrically fixed at the lower end of the inner wall of the limiting groove, and the cross-section of the connecting clip is a semicircular structure. The limiting clip is fixed at the upper end of the inner wall of the limiting groove.
[0011] Furthermore, a flexible circuit board is fixed to one side of the upper end surface of the metal spring sheet, and the flexible circuit board is clamped on the inner side of the positioning hole and connected by glue.
[0012] Furthermore, a second positioning column is fixed to the inner wall of the positioning groove, the first positioning column and the second positioning column are slidably engaged with the inner side of the key plate, and the key plate is closely fitted to the surface of the metal spring sheet.
[0013] Furthermore, a key body is evenly fixed on the outer side of the key plate, a locking card is evenly fixed on the outer side of the key body, and the locking card is clamped with the inner wall of the decorative body.
[0014] Furthermore, a stepped slot is provided on the outer side of the positioning slot, and the decorative body is embedded in the stepped slot and sleeved on the outer side of the button body. The inner wall of the decorative body is evenly provided with corrugated parts and the corrugated parts are in contact with the inner wall of the stepped slot.
[0015] The utility model has the following beneficial effects:
[0016] The utility model can limit the position of the metal spring piece by setting a limit groove and a connecting mechanism to avoid the metal spring piece from being offset. Then, the positioning groove and the positioning column can cooperate to limit the key panel to avoid the key panel from being offset. At the same time, the locking clip on the outside of the key body can be connected to the decorative body, so that the metal spring piece, the key panel and the decorative body can be quickly disassembled and replaced with the main shell.
