Description

Technical Field

[0001] The utility model relates to the technical field of cable intermediate joints, and specifically relates to a cable intermediate joint with a waterproof sheath. Background Art

[0002] As is well known, a cable intermediate joint refers to a component connecting two sections of cables in a cable line, used to extend or connect cables. Cable intermediate joints are usually used in fields such as power systems, communication systems, and data transmission systems to connect two sections of cable lines when needed.

[0003] The utility model patent with the publication number CN215419541U discloses a cable intermediate joint, including a body. A fixing hole axially penetrating the body is provided on the body, and the fixing hole is the same as the central axis of the body. The body includes an insulating end and a semiconductor end, and the insulating end and the semiconductor end are integrally formed. Sealing parts are provided at both ends of the body, and a sealing through hole is provided in the sealing part. The sealing through hole gradually narrows from one end close to the body to the other end. The sealing part includes a first sealing part and a second sealing part, and the first sealing part and the second sealing part are hermetically connected to both ends of the body. This cable intermediate joint has a simple structure, is easy to use, and has strong safety.

[0004] However, the existing cable intermediate joints still have certain deficiencies: First, because the existing cable intermediate joints are not produced by the original factory, various cable joints have serious potential safety hazards during operation. Cable sensors can only be installed on the outer surface of the cable insulation, and the condition of the cable inner core cannot be detected in a timely and accurate manner.

[0005] Secondly, most of the existing cable intermediate joints simply use their own material properties to waterproof the butt - jointed cables, which obviously causes poor waterproofing effect of the cable intermediate joints. Moreover, most of the existing cable intermediate joints simply rely on natural air cooling for heat dissipation treatment, which is likely to cause poor heat dissipation effect. Summary of the Utility Model
