Abstract

The invention provides a vehicular switch waterproof structure comprising a button, a housing, a bracket, a conductive rubber pad, a printed circuit board, a base and a pin, wherein the pin is embedded in the base; the printed circuit board is mounted on the base; the pin is soldered to the printed circuit board; the conductive rubber pad covers the upper side of the printed circuit board; and thebase and the housing are buckled. The vehicular switch waterproof structure can protect the functions of the internal components and the circuits of an electrical switch, thereby ensuring the effectiveness of the switch under the abnormal conditions of the vehicle.

Description

technical field [0001] The invention belongs to the field of auto parts, and in particular relates to a waterproof structure of an auto switch. Background technique [0002] With the development of automotive technology, automotive electronic switches will gradually replace traditional mechanical switches. For example, switches must have control functions such as "anti-pinch", remote control "open and close", and keyless "entry". These humanized needs can only be realized by electronic switches. At the same time, some special positions on the car, such as the positions of doors and windows, are prone to water ingress and accumulation. For the switches installed in these positions, if the protection is not done well, water or other foreign objects can easily oxidize and corrode the components and exposed copper lines on the printed circuit board after entering the switch, causing the switch to fail. Similarly, the water accumulated in the car door will increase with the tem...
