Description

Technical Field

[0001] The utility model relates to the field of cable connection, in particular to a protective device for power cable connection. Background Art

[0002] Power cable is a cable product used to transmit and distribute high-power electric energy in the trunk line of the power system. During the construction of power engineering, it is usually necessary to connect the cables to complete the connection and laying between the circuits. During the wiring process, the cables are generally set outdoors, so the protection of the cables is generally more important. In recent years, cable junction boxes are mostly used for outdoor protection of cable wiring. The junction box is one of the electrical auxiliary materials. When in use, in order to protect the wires, the wire tube will be connected to the two ends of the junction box. The wires pass through the wire tube and then connect in the junction box. The setting of the wire box can effectively protect the wires and connect the wires. The existing cable wiring protection device has a poor fixing effect on the cable, and it is easy to cause the cable connection to loosen when pulling the cable. In order to solve the above-mentioned problems, some protective devices usually have multiple clamps inside the device, and then fix the clamps with screws to fix the cables, so as to fix the cables, but this fixing structure is relatively cumbersome and not very practical.

[0003] According to a power cable wiring protection device provided by patent application number CN202220361417.0, it includes an upper shell and a lower shell; wherein, semicircular holes are provided at both ends of the bottom of the upper shell, and semicircular holes are also provided at both ends of the top of the lower shell; a sealing rubber A is provided on the inner side of the multiple semicircular holes; a winding post is fixedly provided at both ends of the inner side of the lower shell, and a wire groove is provided on the winding post; a compression rubber block is provided at both ends of the inner wall of the upper shell; a sealing rubber B is provided at the top of the lower shell, and a sealing groove matching the sealing rubber B is provided on the upper shell; an upper fixing bar is provided at the bottom of the upper shell, and a plurality of butterfly bolts are threadedly connected on the upper fixing bar, and a lower fixing bar is provided at the top of the lower shell, and a plurality of threaded barrels threadedly connected with the butterfly bolts are provided on the lower fixing bar. The utility model can play a good fixing role on the cable, prevent the cable from loosening, thereby ensuring the connection effect of the cable.

[0004] There are still some shortcomings in the patent application. The patent can fix the cables well and prevent them from loosening, thereby ensuring the connection effect of the cables. However, the staff needs to wrap the cables and then align them for wiring. After the cables enter the protective device, the two cables cannot be kept in the same straight line position, thus reducing the wiring efficiency. Therefore, a protective device for power cable wiring is needed to solve these problems. Utility Model Content
