Description

Technical Field

[0001] This utility model relates to the field of electrical connection technology, and more specifically, to a power distribution line switching device. Background Technology

[0002] Power distribution lines refer to the lines that carry electricity from a step-down substation to a distribution transformer or vice versa, and then deliver the electricity from the distribution substation to the user. During the installation of power lines, it is usually necessary to connect and secure two wires together.

[0003] A search revealed a utility model patent with publication number CN220732344U, which discloses a power distribution line conversion device. The device includes a first arc-shaped plate, a docking mechanism, a second arc-shaped plate, and a limiting mechanism. The docking mechanism is located on the first arc-shaped plate, which serves as the connection base. The power distribution line conversion device uses a hinge to allow the first and second arc-shaped plates to rotate and connect. A rotating threaded sleeve causes one end of a bolt to engage and fix below an opening block. This allows the user to quickly connect the first and second arc-shaped plates using the docking mechanism. The first and second arc-shaped plates prevent aging after prolonged use, extending their service life. Lifting an insulating block causes a female buckle to engage and fix on a male buckle. The two sets of insulating blocks compress and deform the first and second wires, securing them. The limiting mechanism allows the user to fix the first and second wires, preventing them from detaching during docking, causing poor contact, or other unexpected situations, thus improving safety. However, the aforementioned patent has the following shortcomings: the convenience of fixing the first and second arc-shaped plates together using bolts and threaded sleeves is not ideal, requiring the use of tools such as screwdrivers for installation; furthermore, when two connected wires are suspended in the air, the connection point will be subjected to tensile force, affecting the quality of the wiring connection. Therefore, we propose a power distribution line switching device. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a power distribution line switching device.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A power distribution line switching device includes a lower switching box and an upper switching box. Silicone insulating blocks are fixedly sleeved in the middle of the inner cavities of both the lower and upper switching boxes. Each silicone insulating block has an inner arc-shaped groove. The bottom surface of the upper switching box and the top surface of the lower switching box are in contact with each other. A first wire is sleeved at one end of the inner cavity of both the lower and upper switching boxes, and a second wire is sleeved at the other end of the inner cavity of both the lower and upper switching boxes. The ends of both the second and first wires extend into the inner cavity of the arc-shaped groove and are interconnected. The lower adapter box has multiple winding posts fixedly connected to both ends of its inner cavity, and multiple insertion tubes fixedly connected to both ends of its inner cavity. The top of each winding post is movably sleeved into the inner cavity of the insertion tube. The middle parts of the first and second wires are wound around the outside of the multiple winding posts. U-shaped brackets are fixedly connected to both sides of the lower adapter box, and connecting blocks are fixedly connected to both sides of the upper adapter box. Hooks are fixedly connected to the bottom surfaces of both connecting blocks, and the bottom ends of the hooks are engaged with the inner cavity of the U-shaped brackets.

[0007] As a preferred embodiment of this utility model, the top surface of the lower adapter box is fixedly connected to a plug, the bottom surface of the upper adapter box is provided with a slot, and the top end of the plug is movably sleeved into the inner cavity of the slot.

[0008] As a preferred embodiment of this utility model, both ends of the lower adapter box and the upper adapter box are provided with fixed arc-shaped tubes, and rubber extrusion blocks are fixedly sleeved on the inner walls of the fixed arc-shaped tubes. Extrusion grooves are opened on the rubber extrusion blocks, and the inner walls of the extrusion grooves are in contact with the sides of the first wire and the second wire.

[0009] In a preferred embodiment of this utility model, the inner diameter of the inner arc groove is equal to the outer diameter of the first wire and the second wire, respectively.

[0010] In a preferred embodiment of this invention, the outer diameter of the winding column is equal to the inner diameter of the insertion tube.

[0011] In a preferred embodiment of this utility model, the inner wall of the slot and the side of the insert are fitted together.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] (1) In this utility model, after the first wire and the second wire are connected, the lower adapter box and the upper adapter box are placed on the outside of the connection between the first wire and the second wire. At the same time, the connection between the first wire and the second wire is pressed and fixed in the inner arc groove on the two silicone insulating blocks, and the hooks on both sides of the upper adapter box are inserted into the U-shaped card seats on both sides of the lower adapter box, so as to conveniently fix the lower adapter box and the upper adapter box.

[0014] (2) In this utility model, when the first wire and the second wire are located in the inner cavity of the lower junction box and the upper junction box, the first wire and the second wire are wound on the outside of multiple winding posts respectively. When the first wire and the second wire are pulled, the winding posts that wrap the first wire and the second wire bear the tension, avoiding the connection of the first wire and the second wire from being subjected to a large tension and breaking the circuit, thus improving the practicality of the power distribution line switching device.
