Abstract

The invention discloses a waterproof signal trigger device capable of preventing glue adhesion. The waterproof signal trigger device capable of preventing glue adhesion comprises a permanent magnet and a magnetic induction element. The waterproof signal trigger device capable of preventing glue adhesion is characterized by further comprising a key mechanism, wherein the key mechanism comprises a base and a guide tube, and the guide tube is fixedly connected to the base; a pressing rod is arranged in the guide tube, a key is arranged on the top of the pressing rod, the permanent magnet is embedded in the surface of the pressing rod, the pressing rod and a guide tube seat are in elastic connection through a spring, the permanent magnet can carry out reciprocating motion along with the pressing rod in the stretching and retracting direction of the spring, the magnetic induction element is arranged on a trigger circuit main control panel outside the key mechanism, and the permanent magnet can pass through the induction range of the magnetic induction element in the reciprocating motion process and trigger the magnetic induction element. The waterproof signal trigger device capable of preventing glue adhesion is low in cost, simple in assembly process, high in production efficiency, simple, reasonable and easy to control.

Description

technical field [0001] The invention belongs to the technical field of electronic products, and relates to a signal trigger for electronic products, in particular to a waterproof and glue-proof signal trigger device. Background technique [0002] In electronic products, the signal trigger is generally through a kind of external intervention, so that the signal trigger can realize the control. After the trigger, the signal is transmitted to the central processing unit, and the central processing unit issues instructions, and the actuator realizes the operation. And this kind of external intervention is generally realized through mechanical buttons or magnetic intervention. With mechanical buttons, when the main control circuit board is sealed with moisture-proof requirements, the mechanical buttons will be directly welded on the circuit board. After the circuit board is sealed with glue, the buttons are easily bonded by glue and lose their elasticity; or connect the buttons t...
