Description

Technical Field

[0001] This utility model relates to cable joints, specifically to a middle-wrap type cable joint. Background Technology

[0002] The center-wrap cable joint is a core connection component in power transmission. With its advantages of excellent waterproof sealing and compatibility with zero-margin connections, it is widely used in power transmission and transformation, industrial and mining applications, and other scenarios. It restores the cable structure and stabilizes the electric field by wrapping it layer by layer with functional materials such as semi-conductive tape, stress control tape, and self-adhesive insulating tape, ensuring safe power transmission. In complex connection scenarios, to improve reliability and adapt to the needs of equipment terminals, a copper lug connector is needed from the center-wrap joint. After conductor crimping pretreatment, a matching copper lug is selected, and the cable core is tightly crimped using professional crimping tools to form a robust connection. The two work together to enhance conductivity, reduce the risk of failure, and are suitable for use in high-voltage switchgear, transformers, and other scenarios.

[0003] However, existing cable connectors are not convenient for limiting the cable core during use. The cable core may shift and become loose during connection, causing some copper wire to fall outside the connector. This affects the neatness of the cable core during connection and thus affects the normal connection of the cable. Utility Model Content

By setting a wire-gathering part, it solves the problem that existing cable joints are not convenient for limiting the cable core during use, and the cable core may shift and loosen during connection, resulting in some copper wires being scattered on the outside of the joint, thus affecting the orderly state of the cable core during the connection process and thus affecting the normal connection of the cable.

[0005] To solve the above problems, this utility model provides a middle-wrap type cable joint, including two copper tubes, and further including: a wire-gathering part, wherein two wire-gathering parts are provided, and the two wire-gathering parts are respectively located on the side of the two copper tubes that are far apart from each other; a fixing part, wherein the fixing part is installed on the side of the two copper tubes that are close to each other; the wire-gathering part includes a limiting component, which is installed on the copper tube; a snap-fit ​​component, wherein two snap-fit ​​components are provided, and both snap-fit ​​components are located outside the copper tube; the limiting component includes two connecting rings provided on the copper tube, and a protrusion is fixedly connected to the side of the two connecting rings near the copper tube. A groove is opened on the side of the copper tube near the two connecting rings, and several limiting blocks are fixedly connected to the side of the two connecting rings near the copper tube. Several limiting grooves are opened on the copper tube, and the two protrusions are adapted to the grooves, and the several limiting blocks are adapted to the several limiting grooves respectively.

[0006] In one possible implementation, the fixing part includes positioning components, two of which are respectively located on the side of the two copper tubes that are close to each other; and fixing components, which are installed on the side of the two copper tubes that are close to each other, and the two fixing components are circumferentially distributed.

[0007] In one possible implementation, the snap-fit ​​assembly includes a connecting rod fixedly connected to the bottom of the upper connecting ring, with a circular block fixedly connected to the bottom of the connecting rod. The lower connecting ring has two pressing members, the circular block being an elliptical block. Each pressing member includes a connecting groove formed at the top of the lower connecting ring, with a plurality of elastic rods fixedly connected to the inner wall of the connecting groove. The elastic rods are circumferentially distributed, and the distance between the elastic rods is less than the diameter of the circular block.

By setting up a cable-gathering section, during installation, the protrusion on the connecting ring cooperates with the groove of the copper tube, and the limiting block adapts to the limiting groove to achieve installation positioning. The buckle assembly utilizes the round block at the bottom of the connecting rod of the upper connecting ring to interact with the elastic rod in the connecting groove of the lower connecting ring, so that the two connecting rings are spliced ​​and fixed, thereby achieving the wrapping and limiting of the cable core. It can limit and fix the cable core, and through its own structure, it keeps the cable core in a regular state during the connection process, avoiding the situation of displacement or loosening, providing a stable foundation for the smooth connection of the subsequent cable joint, and enhancing the tightness of the connection between the cable core and related components. 2. By setting a fixing part, during connection, the positioning rod on the second connecting rod and the positioning groove are matched to allow the two copper pipes to be precisely spliced ​​on the side closest to each other, so that the connecting holes remain coaxial. The fixing component places the gasket in the gasket groove, and then the bolt is passed through the two connecting holes. With the help of the nut, the two connecting rods are fixed, thereby achieving a stable connection between the two copper pipes.
