Enter to the bottom of accommodating cavity, to further improve water resistance.
The utility model may further be provided for：The upper shell covers at the outside of lower housing, the side of upper shell
Offering the osculum being connected to accommodating cavity, the upper shell and lower housing can be by the switching circuit board, waterproof in splicing
Set and partition board upper-lower compacting are in the bottom of the accommodating cavity.
It is using the advantages of above-mentioned technical proposal：The setting of osculum enables to enter the rainwater in accommodating cavity from draining
It is discharged in hole, avoids the occurrence of ponding, improve water resistance.Since the upper shell and lower housing can be by the switches in splicing
Circuit board, waterproof jacket and partition board upper-lower compacting make in the bottom of the accommodating cavity between switching circuit board, waterproof jacket and partition board
It is bonded even closer, so as to reduce gap, prevents from seeping water.
