Description

Technical Field

[0002] A surge, also known as a sudden surge, is a momentary overvoltage exceeding the normal operating voltage. A surge protector, also known as a lightning arrester, is an electronic device that provides safety protection for various electronic devices, instruments, and communication lines.

[0072] By respectively providing first soldering pads on the front and rear end surfaces of the circuit board 12, the lightning protection module 2 and the alarm module 11 are welded. When the lightning protection module 2 derives the peak current or voltage, the current is then derived through the alarm module 11, and the two ends of the conductive ring 133 connect and conduct the two first soldering pads on both sides of the circuit board 12; second soldering pads are respectively provided on the front and rear end surfaces of the circuit board 12. When the lightning protection module 2 trips, due to the high temperature, the welding point between the lightning protection module 2 and the alarm module 11 is melted, that is, the soldering between the lightning protection module 2 and the alarm module 11 is desoldered, the alarm module 11 moves, and at the same time, the conductive module 13 on the extension line of the movement trajectory of the alarm module 11 is started to rotate, and the two second soldering pads on both sides of the circuit board 12 are conducted, that is, the circuit board 12 sends a second electrical signal. After the signal change sent by the circuit board 12 is sent, an alarm is realized.

[0073] Among them, the second soldering pad is located on the upper side of the first soldering pad, that is, when the lightning protection module 2 and the alarm module 11 are welded, the conductive ring 133 can only conduct the first soldering pad. When the lightning protection module 2 and the alarm module 11 are desoldered, the conductive ring 133 rotates under the action of the force of the alarm module 11, thereby realizing that the two ends of the conductive ring 133 are conducted to the second soldering pad located at the upper end of the first soldering pad.

[0074] The present invention also provides a surge protector, comprising: a lightning protection module 2 and the alarm device 1 .
