[0023] As Figure 2As shown in the figure, a specific implementation of the remote signaling switch structure in the above embodiment is disclosed in an embodiment of the present utility model, including: a housing having a plug-in convex portion that can cooperate with a window structure on the mounting base module; the housing specifically includes a detachable upper cover 4 and a lower cover 5; the lower cover is used to accommodate a circuit board 6, a remote signaling terminal 7, a key switch 8, a sliding rod 9, and a spring 10, and the upper cover covers the upper part of the lower cover. A circuit board is disposed inside the housing; a key switch is connected to the circuit board and disposed on the front of the circuit board; a remote signaling terminal is connected to the key switch through the circuit board and disposed on the back of the circuit board for transmitting the switching value of the key switch to the upper computer; a sliding rod is disposed in front of the key switch, and a spring is provided between the tail of the sliding rod and the key switch. When the head of the sliding rod abuts against the swing arm of the tripping link inside the surge protector, the spring can be compressed, thereby triggering the key switch. When the head of the sliding rod extends into the pore on the swing arm of the tripping link, the spring is released, thereby releasing the key switch; one end of the spring contacts the sliding rod, and the other end of the spring contacts the key switch, enabling the sliding rod to translate back and forth.

[0024] As Figure 7 shown, according to the above embodiment, preferably, the housing of the remote signaling switch structure has a snap structure, and the snap structure is detachably connected to the window structure 23. The housing has a plug-in convex portion 24 that can cooperate with the window structure 23 on the mounting base module.

[0025] According to the above embodiment, preferably, a spring guide groove is provided inside the lower cover for placing the spring.

[0026] According to the above embodiment, preferably, the connection port of the remote signaling terminal is exposed outside the housing.

[0027] As Figure 3 shown, a specific implementation of the surge protection element module in the above embodiment is disclosed in an embodiment of the present utility model, including: a protector housing 11, a tripping link 12, a torsion spring 13, a varistor 14, an input electrode piece 15, and an output electrode piece 16; the torsion spring is fixed on the inner wall of the protector housing, the tripping link is connected to the torsion spring, and both ends of the tripping link can rotate around the center of the torsion spring. When the torsion spring is in a compressed state, one side swing arm of the tripping link is welded and fixed to the varistor, and the other side swing arm of the tripping link contacts the sliding rod of the remote signaling switch structure. The varistor is fixed inside the protector housing, the input end of the varistor is connected to the input electrode piece, the output end of the varistor is connected to the output electrode piece, the input electrode piece and the output electrode piece are fixed inside the protector housing, and the head of the electrode piece extends outside the protector housing for plugging and cooperating with an external clip spring structure.

[0028] According to the above embodiment, preferably, it further includes: an indicating bar disposed inside the protector housing, corresponding to an observation window on the protector housing, and connected to one end of the tripping link, and capable of moving under the drive of the rotation of the tripping link.

When the surge protection element module fails (see Figure 6 ): the low-temperature tin between the tripping link and the varistor melts, under the action of the torsion spring, the tripping link rotates to pull the indicating bar 22 to turn the observation window of the surge protection element module red. At the same time, the sliding rod extends into the pore on the swing arm of the tripping link, the spring releases, the sliding rod moves forward, so that the push-button switch is released, and the signal is transmitted to the telecommunication terminal through the circuit board, and then transmitted to the external terminal device, so as to facilitate the terminal device to monitor the surge protector, as well as fault troubleshooting and maintenance.

[0031] When the surge protection element module does not show a red indication, but the terminal device receives a signal that the surge protector fails, then there is a problem with the telecommunication switch module. Just release the fixing position restriction of the telecommunication switch module, and the telecommunication switch module can be taken out and replaced, without replacing the whole machine, reducing the operation and maintenance cost.

[0032] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
