Connector anti-loosening structure for underground high-temperature-resistant and high-voltage-resistant cable

Abstract

The invention discloses a connector anti-loosening structure for an underground high-temperature-resistant and high-voltage-resistant cable, and relates to the technical field of cable laying and mounting equipment. The connector anti-loosening structure comprises a cable connector body, wherein the surface side wall of the cable connector body is sleeved with a mounting ring, storage plates are fixed to the left side wall and the right side wall of the mounting ring, storage openings are formed in the side walls, which are close to the mounting ring, of the storage plates, baffles are arranged in the storage openings, an adjusting column is arranged between the mounting ring and a locking cap, a movable hole is formed in the left side of the interior of the limiting hole, a movable rod is arranged on the right side of the adjusting column, clamping plates are fixed to the right ends of the movable rods, and movable plates are fixed to the left ends of the movable rods. According to the invention, the locking cap is abutted and blocked by the four clamping plates, the anti-loosening stability is improved, the movable plate moves in the movable hole, so that the distance of the clamping plates is adjusted, the adjustment work is carried out according to the position of the locking cap, the top plate is moved into the storage opening of the storage plate, and the mounting ring is conveniently detached and taken out from the cable connector body.

Description

technical field [0001] The invention belongs to the technical field of cable laying and installation equipment, in particular to a joint anti-loosening structure used for underground high-temperature and high-voltage cables. Background technique [0002] Cables are often laid in cable trenches, tunnels, pipes or indoors. After entering the modern society, due to the shortage of urban land, high traffic pressure, city appearance construction and other reasons, large cities generally use underground cable transmission methods. Compared with overhead lines, cables have a large area. Small size, reliable power transmission, strong anti-interference ability, etc., when laying underground cables, cable joints are often used; [0003] The cable joint is also called the cable head. After the cable is laid, in order to make it a continuous line, each section of the line must be connected as a whole. The cable joint in the middle of the cable line is called the middle joint, and the c...

Problems solved by technology

[0004] 1. When the existing connectors are connected to the cables, the connectors will become loose after a long time of connection, resulting in unstable connection between the two cables and easy disconnection, which will cause two The temperature of the cable connection is too high, and a short circuit occurs;

[0005] 2. There is no ability to adjust the limit distance according to the locking distance of the joint, so when the locking distance of the joint changes, the locking structure of the joint cannot be effectively limited, which in turn affects the practical performance of the anti-loosening structure;

[0006] 3. Since there is no detachable function, when the anti-loosening structure is damaged, it cannot be effectively disassembled, resulting in the inability to perform anti-loosening work on the joints, which will affect the normal use of the joints

[0007] Therefore, the existing joint anti-loosening structure of underground high-temperature and high-voltage cables cannot meet the needs of actual use, so there is an urgent need for improved technology on the market to solve the above problems
