Problems solved by technology

For 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 door will increase with the temperature inside the car, and the accumulated water will generate water vapor, which will enter the switch through the gap of the switch structure and corrode the switch components, making the switch function invalid.

Abstract

The invention discloses an automotive switch protection structure which comprises a button (1), a shell (2), a support (3), a conducting adhesive pad (5), a PCB (6), a base (7) and a contact pin (8). The contact pin (8) is embedded in the base (7), the PCB (6) is arranged on the base (7), the contact pin (8) is welded on the PCB (6), the conducting adhesive pad (5) covers the PCB (6), and the base (7) is buckled with the shell (2). The automotive switch protection structure can effectively protect functionality of components and circuits in an electric switch, and guarantees effectiveness of the switch when an automobile is under an abnormal condition.

Description

technical field [0001] The patent of the present invention relates to a waterproof protection structure of a vehicle 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 temperature inside the...
