In some embodiments, a rubber pad is arranged at the bottom of the wedge-shaped clamping groove.
In some embodiments, the rubber pad is made of natural rubber.
In some embodiments, the first housing and the second housing are further provided with a plurality of notches for placing the contacts and the buttons.
In some embodiments, a sealing ring is arranged at each notch.
(III) advantageous effects
Compared with the prior art, the utility model has the beneficial effects that:
(1) the wedge-shaped fixture block and the wedge-shaped clamping groove are arranged on the top surfaces of the side walls of the first shell and the second shell, so that the traditional mode that the fixture block and the clamping groove are arranged on the side wall of the shell and are easy to connect and disconnect is replaced, and an additional auxiliary tool is not needed;
(2) according to the utility model, the rubber pad made of natural rubber is arranged at the bottom of the wedge-shaped clamping groove, so that the rubber pad has better elasticity, and after the wedge-shaped clamping block is inserted into the wedge-shaped clamping groove, the rubber pad is extruded by the wedge-shaped clamping block to fill the gap between the wedge-shaped clamping groove and the wedge-shaped clamping block and simultaneously provide an upward reaction force for the wedge-shaped clamping block, so that the connection strength and tightness of the first shell and the second shell are enhanced.
