Problems solved by technology

[0004] However, when the line is struck by lightning or overvoltage, the lightning protection device will generate a lot of heat under the condition of continuous overcurrent or overvoltage, which will cause fire and burn if the time is too long, and the safety of the line cannot be guaranteed.
Moreover, in the prior art, the temperature insurance is connected in series in the line, sometimes it is difficult to disconnect the temperature insurance, causing the line to overheat and burn, and the cost is relatively high

Abstract

The embodiment of the invention discloses an onboard surge protection device. The device comprises a circuit board, a lightning protection device which is soldered on the circuit board through a solder, and an elastic component which comprises a first end and a second end. The first end of the elastic component is fixedly connected with the circuit board. The second end of the elastic component isfixedly connected with the lightning protection device. The elastic component stores elastic potential energy. According to the technical scheme provided by the embodiment of the invention, when a line is subjected to lightning strike or surge voltage, the lightning protection device can sure that the lightning protection device can be disconnected from the line in time in the case of continuousovercurrent. The line safety is ensured. Fire and burning are prevented. The cost is low.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of lightning protection, and in particular to a board-mounted surge protection device. Background technique [0002] Surge protection devices provide safety protection functions for various electronic equipment, instruments and meters, and communication lines, and are widely used. The performance of surge protection devices is directly related to whether the related equipment can work safely and reliably. [0003] The surge protection devices in the prior art use a separate voltage-limiting lightning protection component or a switch-type lightning protection device and a voltage-limiting lightning protection device in series for line protection in order to protect the safe operation of electronic equipment. [0004] However, when the line is struck by lightning or overvoltage, the lightning protection device will generate a lot of heat under the condition of continuous overcurrent or ov...
