Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] The present utility model provides as Figure 1-6A low-voltage semiconductor discharge tube shown in the figure includes a semiconductor discharge tube body 100. The composition of the semiconductor discharge tube body 100 can refer to a discharge tube disclosed in the utility model patent with the authorized announcement number of CN216818335U in the prior art, which can have a reduced blocking voltage and on-state voltage drop, and achieve low-voltage breakdown adjustment. It also includes a protective jacket 200, a splicing square tube 300, a splicing rod 400, and a locking mechanism. The protective jacket 200 is fixedly sleeved on the outer wall of the semiconductor discharge tube body 100. Both ends of the protective jacket 200 have through holes for the cable to pass through. The protective jacket 200 is used for the protection of the outer wall of the semiconductor discharge tube body 100. By sleeving the protective jacket 200 on the outside of the semiconductor discharge tube body 100, the external protection of the semiconductor discharge tube body 100 can be realized, and the overall anti-pressure and anti-collision performance can be improved. The splicing square tube 300 is fixedly connected to one side of the protective jacket 200. A splicing channel 302 is opened in the middle of the protective jacket 200. The splicing rod 400 is fixedly connected to the side of the outer wall of the protective jacket 200 away from the splicing square tube 300. The outer wall of the splicing rod 400 can be inserted into the inside of the splicing channel 302. The locking mechanism is installed at the end of the splicing square tube 300. The locking mechanism is used for locking and fixing the position of the splicing rod 400 in the splicing channel 302. When multiple semiconductor discharge tube bodies 100 need to be installed side by side, only need to insert the splicing rod 400 on the outer wall of the protective jacket 200 of the semiconductor discharge tube body 100 into the splicing channel 302 of the splicing square tube 300 on the outer wall of the protective jacket 200 of the adjacent semiconductor discharge tube body 100, then the splicing positioning between the two semiconductor discharge tube bodies 100 can be completed. Then, with the cooperation of the locking mechanism to realize the locking and fixing of the position between the splicing square tube 300 and the splicing rod 400, the stability of the splicing of the adjacent two semiconductor discharge tube bodies 100 can be enhanced.

[0026] In some embodiments, the protective jacket 200 includes a protective sleeve 202.

Further, a plurality of slots 203 are spaced apart on the side edge of one end of the protective sleeve 202. A limiting through groove 204 communicating with the end of the slot 203 is opened on the outer wall of the protective sleeve 202. An elastic buckle 205 is fixedly connected to the side edge of the side of the end cap 201 facing the protective sleeve 202. The elastic buckle 205 is movably inserted into the slot 203 and the limiting through groove 204. When the end cap 201 is butted against the port of the protective sleeve 202, the elastic buckle 205 is inserted into the slot 203 and restricted in the limiting through groove 204, so that the end cap 201 can be locked and fixed at the port position of the protective sleeve 202. When disassembling, only need to press the elastic buckle 205 at the position of the limiting through groove 204 to release the inserted and locked state between the two to unlock the end cap 201. The operation is simple and convenient, and at the same time, the locking firmness is high. In a preferred embodiment, the elastic buckle 205 is composed of an L-shaped elastic piece 251 and a wedge-shaped block 252. The L-shaped elastic piece 251 and the wedge-shaped block 252 are integrally formed structures. The side wall of the L-shaped elastic piece 251 is fixedly connected to the side edge of the side wall of the end cap 201. The wedge-shaped block 252 is located at one end of the L-shaped elastic piece 251 away from the end cap 201. The L-shaped elastic piece 251 has the characteristic of elastic deformation. Cooperating with the shape characteristics of the wedge-shaped block 252, it is convenient for the elastic buckle 205 to be inserted or unlocked and pulled out in the slot 203 and the limiting through groove 204.
