Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage cables, in particular to a high-voltage or extra-high-voltage cable conductor connector. Background Art

[0002] High-voltage cable is a type of power cable, mainly used to transmit electricity between 1kV and 1000kV. It is widely used in power engineering, communication engineering, petroleum, chemical industry, construction and other fields. High-voltage cable is usually made of copper or aluminum and has good electrical conductivity. High-voltage cable is widely used in various fields.

[0003] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when connecting two sections of high-voltage or ultra-high-voltage cables together, a dedicated connector is generally used. Since most connectors lack auxiliary connection mechanisms, multiple other tools are needed to fix and limit the cables when making connections. However, most cables need to be operated outdoors, and carrying other tools can easily cause inconvenience in transportation and operation. Therefore, a high-voltage and ultra-high-voltage cable conductor connector is proposed to address the above problems. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0005] The technical solution adopted by the utility model to solve its technical problems is: the utility model describes a high-voltage and extra-high-voltage cable conductor connector, comprising a sleeve and a fixing device, the inner wall of the sleeve being inserted with two cables, the inner wall of the sleeve being threadedly connected with a plurality of positioning posts, and the positioning posts being located on the surface of the cable; the surfaces of the sleeve and the two cables are provided with fixing devices, and the fixing device comprises a placing plate, the placing plate being located on the side wall of the sleeve, the surface of the sleeve being covered with a clamping ring, the side wall of the clamping ring being fixedly connected to the side wall of the placing plate, the inner wall of the placing plate being slidably connected with two movable rings, the surface of the movable ring being rotatably connected with a swivel, and the swivel is covered on the surface of the cable. When connecting the two cables, the movable ring is pushed to allow the movable ring to drive the cable to move, and the cable is inserted into the inner wall of the sleeve. By arranging the placing plate, the clamping ring, the movable ring and the swivel, the sleeve and the cable can be conveniently connected, and the cable can also be guided.

[0006] Preferably, the inner surface of the placement plate is rotatably connected to two threaded rods, and the surfaces of the threaded rods are threadedly connected to the inner wall of the movable ring. When the position of the movable ring needs to be adjusted, the threaded rods are rotated to allow the threaded rods to rotate on the inner wall of the movable ring. By setting the threaded rods, the position of the movable ring and the cable can be adjusted.

[0007] Preferably, two receiving grooves are provided on the surface of the placement plate, and the inner wall of the receiving groove of the placement plate is slidably connected to the surface of the movable ring. When the movable ring moves, the movable ring slides on the inner wall of the receiving groove. The provision of the receiving groove can facilitate the movement of the movable ring.

[0008] Preferably, two anti-slip sheets are fixedly connected to the placement plate and the clamp ring surface near the sleeve. The anti-slip sheets are located on the surface of the sleeve. When the sleeve moves, the sleeve will be squeezed on the surface of the anti-slip sheets. The setting of the anti-slip sheets can reduce the possibility of the sleeve moving around on the placement plate and the inner surface of the clamp ring.

[0009] Preferably, the inner surfaces of the movable ring and the clamping ring are fixedly connected with a plurality of anti-slip strips, and the surface of the movable ring is provided with a threaded hole. The inner wall of the threaded hole of the movable ring and the surface of the threaded rod are threadedly connected. When the cable moves, it will be squeezed on the surface of the anti-slip strip. The setting of the anti-slip strip can reduce the possibility of the cable falling out of the movable ring and the rotating ring.

[0010] Preferably, two driving devices are provided on the surface of the placement plate, and the driving devices include a motor. The surface of the motor is fixedly connected to the inner surface of the placement plate, and the side wall of the threaded rod is fixedly connected to a turntable. The turntable and the output end surface of the motor are engaged with a belt. The belt drives the turntable to rotate, and the turntable drives the threaded rod to rotate. By setting the motor, turntable and belt, the threaded rod can be driven to rotate.

[0011] Preferably, a sealing plate is fixedly connected to the side wall of the placement plate near the motor, and a protective cover is fixedly connected to the position of the placement plate near the turntable. The protective cover is sleeved on the surface of the motor output end, the turntable and the belt. The protective cover is located on the side wall of the sealing plate, and the protective cover will fit the sealing plate. By setting the protective cover and the sealing plate, the motor, turntable and belt can be protected.

[0012] The utility model is beneficial in that:

[0013] The cable is then inserted into the sleeve and the positioning post is rotated to the inner wall of the sleeve, and the positioning post is pressed against the cable surface. By setting the entire device, the position of the sleeve and the cable can be restricted, thereby assisting in fixing the cable to the inner wall of the sleeve, reducing the use of other tools, simplifying the equipment and increasing the convenience of carrying.

[0014] 2. When the threaded rod needs to be used, the utility model puts the belt on the output end of the motor and the surface of the turntable, and then pushes the shield to let the shield be put on the surface of the motor output end, the turntable and the belt. The shield will fit the sealing plate. After the shield fits the placement plate, the shield is fixed to the surface of the placement plate, and then the motor is started to drive the belt to move. The belt drives the turntable to rotate, and the turntable drives the threaded rod to rotate. By setting up the entire device, manual operation can be reduced, and the smoothness and accuracy of the movement of the moving ring can also be increased. BRIEF DESCRIPTION OF THE DRAWINGS
