A further technical scheme is that the button and the wall hanging support are made of PC materials and formed in one-step forming mode.

The electronic component mainboard is fixedly arranged on the inner lining plate through self-tapping screws.

The further technical scheme is that the separation ribs and the threaded columns of the components are arranged on the inner lining plate in advance.

The utility model has the advantages that:

1. the electronic component is optimized in integration, the thickness of the whole product is greatly reduced by combining the improved structure of the buckle and the lining, and the use field is greatly widened. The rear housing forms a protrusion to match the power supply, the protruding portion of the portal and can be embedded in a wall in box 86.

2. During assembly, the whole structure distribution adopts linear distribution, so that the principle of assembly from back to front and from inside to outside can be adopted, and the assembly efficiency is greatly improved.

3. Meanwhile, aiming at the wall-mounted requirement, the shell and the wall-mounted bracket are both designed into new structures, so that the product can be firmly attached to the wall without generating larger gaps, is more beautiful,

4. welt and back housing buckle adopt different buckle structure dislocation design, cantilever type buckle side all add and have the strengthening rib, avoid long-term use to produce the phenomenon that the buckle pine takes off or breaks.
