Description

Technical Field

[0001] The utility model relates to the technical field of cable connection, in particular to an auxiliary connector for cable connection. Background Art

[0002] Cables usually consist of several groups of conductors, each group of conductors is insulated from each other and wrapped with a highly insulating covering layer on the outside. They are mostly erected in the air or installed underground or underwater to transmit electrical energy or signals. Cable connectors are used to connect the cables during laying and subsequent maintenance.

[0003] After the existing cable connection joints are used to train the cables, when the cables are bent or stretched, the wire core connections inside the cables are prone to breakage, resulting in unstable connections. At the same time, only waterproof tape is provided on the outside of the wire core connections, resulting in low overall waterproof performance.

[0004] Patent CN207398810U discloses a cable reinforcement device for power construction, which not only solves the problem of loose cable joints, but also improves the load-bearing capacity when dragging the cable body, and prevents the transition joint of the external cable from loosening with the connecting part at the other end due to improper use or processing. However, the reinforcement device is provided with a hose and a transition joint, which is inconvenient to operate during actual use. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an auxiliary connector for cable connection.

[0006] To achieve this technical purpose, the utility model adopts the following scheme:

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] By providing a clamp at the core connection of the cable and arranging a plurality of connecting plates evenly distributed circumferentially on the outside of the clamp, the bending resistance of the overall cable connection can be greatly improved after the cable is connected, thereby ensuring the stability of the connection. At the same time, by providing an insert block at the end face of the clamp and providing a slot corresponding to the insert block at the connecting groove of the connecting plate, after the cable connection is completed, relative movement between the clamp and the connecting plate can be effectively prevented, thereby further ensuring the stability of the connection.

[0010] Furthermore, a fixing plate is arranged outside one end of the main body, and bolt holes are evenly distributed on the fixing plate along the circumference, and detachable guide rods are arranged at the bolt holes, and the number of the guide rods is at least two. When connecting the cables, the guide rods are used to ensure that the ends of the two cables are in the same straight line, thereby facilitating subsequent connection.

[0011] Furthermore, more than two connecting plates are provided, the connecting plates are evenly distributed in the installation groove, and the ends of the connecting plates abut against the inner wall of the installation groove.

[0012] Furthermore, an insert block is provided on the outer end surface of the clamp, a slot is provided in the connecting groove of the connecting plate, and the slot is cooperatively connected with the insert block.

[0013] Furthermore, a flame retardant layer is provided between the main body and the connecting plate, and the flame retardant layer is formed by winding a waterproof and flame retardant tape.

[0014] Furthermore, a sealing gasket is provided at one end of the main body, and a connecting hole is opened on the sealing gasket, and the connecting hole is aligned with the bolt hole. After the cable connection is completed, the two side surfaces of the sealing gasket abut against the end surface of the main body, thereby effectively improving the sealing performance of the cable at the connection.
