[0031] The interior of housings A11 and B12 has multiple fixing screw holes. The interior of housings A11 and B12 has symmetrical cable entry mounting slots near both sides. The center of the inner wall of housings A11 and B12 is provided with a surge protection chip limiting block. The surge protection chip limiting block is an integral structure with the housing. The surge protection chip 7 is located inside the surge protection chip limiting block. The surge protection chip limiting block restricts the surge protection chip 7 to the center of the housing, which improves the stability of the device.

[0032] Both housing A11 and housing B12 have an insulating coating on their inner walls. Housing A11 has a snap-fit ​​positioning block 10 on its inner wall. The snap-fit ​​positioning block 10 is an integral structure with housing A11.

[0035] Working principle: The surge protector is connected to the L(N) line or grounding line in the circuit via input terminals A2 and B3. Under normal circumstances, when there is no transient overvoltage or lightning strike induction in the circuit, the surge protector chip presents a high impedance. However, as the surge current and voltage increase, its impedance will continuously decrease. When the transient voltage caused by the lightning strike is too high, it will rapidly reduce the resistance and discharge the powerful lightning current to the ground. Its current-voltage characteristics are strongly nonlinear, thereby limiting the surge voltage within the voltage range that the equipment or system can withstand, protecting the protected equipment or system from damage due to impact. When the surge protector discharges too much power, the surge protector chip will rapidly heat up, causing the low-temperature solder point to melt. Under the action of elastic potential energy, the spring 6 will automatically and quickly disconnect the discharge circuit from the surge protector chip lead and contact the conductive copper tube, connecting the fault indication circuit and lighting up the LED to prompt the user to replace it.

[0036] The surge protector has a simple structure and high safety, providing excellent lightning protection for the entire circuit, and also has a failure indication function.
