The control board and power board are placed parallel to each other, with the control board fixed to the top of the double-ended screws by screws. The control board and power board are connected by a flexible PCB, and the power board and control board are connected by a power connector. The connector is mounted on the control board. The connector has high airtightness requirements, corresponding to the production line airtightness test method: inflation for 15 seconds, pressure holding for 8 seconds, pressure 50 kPa, test for 7 seconds, leakage less than 100 Pa. In the existing patent, the sealing cover and connector are separate structures, and the waterproof sealing performance inside the sealing cover is poor. Utility Model Content
