Description

Technical Field

[0002] Lightning arrester: An electrical appliance used to protect electrical equipment from high transient overvoltage hazards during lightning strikes, and to limit the follow-on time, and often also the follow-on amplitude. Lightning arresters are sometimes also called overvoltage protectors and overvoltage limiters. There are many types of lightning arresters. The main working principles of each type of lightning arrester are different, but their working essence is the same, which is to protect communication cables and communication equipment from damage.

[0003] A Chinese patent with publication number (CN218447403U) discloses a separate lightning arrester, which includes an insulating protective shell, a fixed base is arranged on the upper and lower sides of the insulating protective shell, a conductive base is arranged in the middle of the fixed base, and a split structure is formed between the fixed base and the conductive base, a fixed plate is arranged at the lower end of the conductive base, and fixed shafts for limiting the fixed plate are arranged on both sides of the fixed base, and a spring is arranged on the fixed shaft. The lightning arrester and the conductive base are separated by pulling the fixed shaft, so that quick separation is achieved and disassembly is facilitated.

[0004] The defect of the above-selected technology is that the locking plate is locked by two fixing bolts distributed on the side of the fixed base. When separating the conductive base and the fixed base, it is still necessary to use a disassembly tool to remove the four fixing bolts. When disassembling and maintaining multiple lightning arresters, the workload is huge and the maintenance efficiency is low. Utility Model Content

[0005] The purpose of the utility model is to provide a lightning arrester to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lightning arrester, comprising an insulating protective shell, wherein a fixed base is arranged on the upper and lower sides of the insulating protective shell, a conductive base is arranged in the middle of the fixed base, the fixed base and the conductive base are detachably connected, two installation grooves are provided on the inner sides of the fixed base, a clamping part is fixedly connected at the bottom of the conductive base and at a position corresponding to the installation groove, a slot is provided at the outer side of the fixed base and at a position corresponding to the installation groove, and a disassembly part is rotatably connected to the outer side of the fixed base.

[0007] As a preferred solution of the utility model, rounded ends are fixedly connected at both ends of the outer side of the fixing portion, and a through groove is provided in the middle of one end of the fixing portion close to the conductive substrate.

[0008] As a preferred solution of the utility model, an annular groove is provided at the bottom edge of the conductive substrate.

[0009] As a preferred solution of the utility model, two protrusions are fixedly connected to the inner wall of the disassembly portion, and the protrusions are slidably connected to the slots.

[0010] As a preferred solution of the utility model, the conductive substrate, the fixed substrate and the disassembly portion are all concentrically arranged.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the utility model, through the disassembly part, the fixing part and the slot and other structures, can directly rotate the disassembly part during disassembly and maintenance, so that the disassembly part will push the fixing part toward the inside of the conductive substrate, causing the fixing part to bend, thereby realizing the separation between the conductive substrate and the fixed substrate, which is quick and convenient. Moreover, under the setting of the installation groove, the installation only needs to push the conductive substrate downward, and the bottom end inclined surface of the fixing part will bend inward under the force, which is convenient for the installation between the conductive substrate and the fixed substrate.
