Description

Technical Field

[0001] The utility model relates to the technical field of cable sheaths, in particular to an insulating cable sheath structure. Background Art

[0002] Cables are commonly used conductive connection devices in large electrical equipment. The cable sheath is the outermost layer of the cable. The cable sheath is mainly used to protect the cable from being damaged by erosion by the external environment, and to prevent people from touching the cable and causing a short circuit or being injured by electric shock.

[0003] Existing cable sheaths are usually formed of plastic injection molding. When the cable needs to be repaired or the sheath is damaged, it is difficult to remove or replace the one-piece sheath. Therefore, in most cases, maintenance workers choose to replace the entire cable, resulting in a lot of unnecessary waste.

[0004] In order to change the above phenomenon, a replaceable rotating cable sheath is disclosed in the Chinese utility model patent with publication number CN217692455U, including a sheath body and a fastening ring, the sheath body includes a left ferrule and a right ferrule, the left ferrule and the right ferrule are symmetrically arranged, the left ferrule and the right ferrule are mutually clamped to form the sheath body, a cable body is arranged between the left ferrule and the right ferrule, the left ferrule and the right ferrule fix and seal the cable body, a group of fastening rings are respectively provided at the upper and lower ends of the sheath body, and the two groups of fastening rings are respectively threadedly connected to the sheath body.

[0005] In the above-mentioned cable sheath, the left ferrule and the right ferrule are semicircular sheath structures that match each other. The fastening ring is threadedly connected to the external thread at the end of the left ferrule and the external thread at the end of the right ferrule, so that the fastening ring fixes the left ferrule and the right ferrule together. However, during actual installation and use, the connection method of the external thread and the internal thread has high precision requirements on the continuous arrangement of the threads. The external thread on the left ferrule and the external thread on the right ferrule are difficult to assemble into an ideal and complete external thread, which will make it difficult for users to connect the two separated semicircular sheaths with the same fastening ring thread. Therefore, related technical improvements are needed. Utility Model Content

[0006] In order to solve the above problems, the utility model provides an insulating cable sheath structure.

[0007] The above technical purpose of the utility model is achieved through the following technical solutions: an insulating cable sheath structure, including a sheath body for use with a cable body, the sheath body including a first jacket and a second jacket, one side of the first jacket is integrally formed with a connecting strip, one side of the second jacket is provided with a connecting groove that cooperates with the connecting strip, a connecting rod that cooperates with the second jacket is penetrated by the second jacket, the connecting rod penetrates the connecting strip and cooperates with the connecting strip, the first jacket and the second jacket are jointly provided with a binding wire for bundling on the outside, and the inner surface of the first jacket and the inner surface of the second jacket are both in contact with the outer surface of the cable body.

[0017] Furthermore, the bolt is a hexagon socket countersunk bolt, and a receiving groove cooperating with the head of the bolt is provided on a side of the arc-shaped plate away from the mounting ring.

[0018] By adopting the above technical solution, the flatness of the inner surface of the arc plate is enhanced, and the probability of the mounting ring, the arc plate and the ball entering the surface of the first rubber block or the second rubber block from the end of the cable body due to the protrusion of the bolt head is reduced.

[0019] Furthermore, both ends of the connecting rod are fixed with limit plates, and the diameter of the limit plates is greater than the diameter of the connecting rod.

[0020] By adopting the above technical solution and setting the limiting plate, the stability of the connection between the connecting rod, the connecting strip and the second jacket is enhanced.
