Description

Technical Field

[0001] This utility model belongs to the field of power distribution equipment technology, specifically relating to a lightning protection device for outdoor power distribution equipment. Background Technology

[0002] Distribution boxes are used for wiring connections between optical cables and optical communication equipment. Many distribution boxes are installed outdoors. When encountering thunderstorms, the high-voltage current generated by lightning strikes can easily damage various components inside the distribution box. Therefore, surge protectors, also called lightning arresters, are often installed inside the distribution box. When a surge current or voltage suddenly occurs in an electrical circuit or communication line due to external interference (such as lightning strikes), the surge protector can conduct and divert the current in a very short time, thereby preventing the surge from damaging other equipment in the circuit.

[0003] However, existing surge protectors have certain shortcomings in use. Surge protectors consist of a base and parallel surge protection units. The surge protection units and the base are detachable, separate structures. When one of the units is damaged, it needs to be replaced in time. The current method of installing surge protection units is generally to use friction to snap them together. If the friction is too tight, disassembly is inconvenient; if the friction is too loose, the installation is not secure. Moreover, with repeated disassembly and assembly, the stability of the connection will decrease, affecting the normal use of the surge protector. Therefore, a new surge protector needs to be designed to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to provide a lightning protection device for outdoor power distribution equipment, so as to solve the problem mentioned in the background art that the existing method of installing lightning protection units by using friction is inconvenient for disassembly and assembly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lightning protection device for outdoor power distribution equipment, comprising a base, an installation groove on the front surface of the base, lightning protection units installed side by side inside the installation groove, and an installation assembly between the upper and lower ends of the lightning protection units and the installation groove, the installation assembly comprising a plug strip, a plug groove, a limiting piece and a limiting slot, the plug strip being fixed to the upper and lower end surfaces of the lightning protection units and slidingly inserted into the plug grooves opened on the upper and lower walls of the installation groove, the limiting piece being slidably installed on the surface of the base and engaging with the limiting slot opened on the protruding end of the plug strip.

[0006] Preferably, the inner wall of the mounting groove is in contact with the outer surface of the lightning protection unit, and the inner wall of the plug groove is in contact with the outer surface of the plug strip.

[0007] Preferably, the mounting assembly further includes a retaining groove formed on the surface of the limiting piece.

[0008] Preferably, the mounting assembly further includes a sliding connecting post and a sliding connecting groove. The sliding connecting post is fixed to the inner surfaces of both ends of the limiting piece and is slidably connected to the sliding connecting groove opened on the surface of the base.

[0009] Preferably, the mounting assembly further includes a rubber damping pad disposed on the inner wall of the sliding connection groove.

[0010] Preferably, the top front surface of the base is provided with an upper connecting terminal, and the bottom front surface of the base is provided with a lower connecting terminal. Protective components are provided on the outer sides of both the upper and lower connecting terminals. The protective components include a protective plate, side strips, a sliding connecting block, a connecting post, and a strip groove. The protective plate is located on the outer surface of the upper and lower connecting terminals. The side strips are symmetrically fixed at both ends of the protective plate. The sliding connecting block is fixed at the end of the side strip. The connecting post is fixed on the inner surface of the sliding connecting block and is slidably connected to the strip groove opened on the surface of the base.

[0011] Preferably, the protective component further includes a snap-fit ​​block and a snap-fit ​​groove, wherein the snap-fit ​​block is fixed side by side to the inner wall of the strip groove and is inserted into the snap-fit ​​groove opened at the inner end of the connecting pile.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By sliding the connector strip into the connector slot, the initial positioning of the surge protection unit can be achieved. Then, the limiting piece is moved so that it inserts into the limiting slot on the connector strip, thereby locking the connector strip in place. This method improves the insertion stability of the connector strip, thus ensuring the installation stability of the surge protection unit. At the same time, the disassembly of the surge protection unit is also simple and quick. Just pull the limiting piece out from the limiting slot, and then pull the connector strip out from the connector slot by snapping the limiting slot. This provides convenience for personnel to disassemble and assemble the surge protection unit. Attached Figure Description
