Electric current sponges the surge current that most of lightning stroke generates by lightning protection varistor SPD first, then remaining surge electricity
Stream is discharged into the earth by gas-discharge tube GDT, and surge protection module is made to complete the release step by step to lightning stroke energy.
It further includes operating mechanism that the present invention, which is further arranged to the breaker of plastic casing with surge protection, the surge protection mould
The top of operating mechanism is arranged in block, and surge protection module includes surge protection module shell and is arranged outside surge protection module
The bottom fixation of wiring board in shell, the conductive insert extends to surge protection mould in the circuit board, at the top of conductive insert
The outside of block shell.
The side that the present invention is further arranged to upper cover forms fluting, and the fluting face surge protection module is described to open
Sealing plate is provided in slot.
It is above-mentioned that in the length for not increasing breaker of plastic casing and surge protection module, surge protection module are set under depth information
Conductive insert is only extended outside to be used to be electrically connected, it is ensured that surge protection module internal circuit board and breaker of plastic casing other structures
Keep apart, sealing plate further strengthens the safety and stability that product uses.
The present invention is further arranged to form circular hole on conductive insert, and the conductive clip includes first clamping piece and the second folder
Piece, the medial surface of first clamping piece and the medial surface of second intermediate plate form symmetrical salient point, and the conductive insert passes through circular hole
It is connect with the cooperation of two salient points with conductive clip.
The present invention is further arranged to first clamping piece close to the side of conductive insert and second intermediate plate close to conductive insert
Fold forms guide portion outward for side.
The present invention is further arranged to the piece number of conductive insert and the piece number of conductive clip is 5.
When the terminal plate of above-mentioned surge protection module and breaker of plastic casing connects, guiding role of the conductive insert in guide portion
Under, it is connected between first clamping piece and second intermediate plate, firm be electrically connected is realized under cooperation of the salient point with circular hole.
