Copper shell of cable intermediate joint

Abstract

The invention relates to a copper shell of a cable intermediate joint. The copper shell is formed by two portions which are capable of being connected together. The two portions are a left copper shell body and a right copper shell body. The left copper shell body comprises an inner copper tube, an outer copper tube and insulating layers arranged on the outer surface of the inner copper tube and the inner surface and the outer surface of the outer copper tube. The outer diameter of the inner copper tube is smaller than the inner diameter of the outer copper tube. One end of the inner copper tube is fixedly connected with one end of the outer copper tube through the insulating layers, but the inner copper tube is not in electrical connection with the outer copper tube. The right copper shell body comprises a right copper tube and an insulating layer arranged on the outer surface of the right copper tube. One end, away from the inner copper tube, of the outer copper tube and one end of the right copper tube are provided with connecting devices. Through the technical scheme, the copper shell can improve the shielding effect of the cable joint and is convenient to operate.

Description

technical field [0001] The invention belongs to the electrical field, and specifically refers to a copper shell used for shielding the outer side of an intermediate joint of a cross-linked cable. Background technique [0002] In long-distance wiring or cable installation, it is usually necessary to connect two cables together to increase the length of the cable. In addition to the wires, the cable usually also includes a shielding layer and an outer insulating layer. When connecting cables, it is necessary to destroy the shielding layer and insulation protection layer at the connection. [0003] For the insulation layer of the cable, the insulation treatment can be realized as long as the insulating tape is applied, but the protection strength of the connection is not easy to achieve. In addition, the most important shielding layer is very difficult to handle. Therefore, the current technology adopts the method of wearing a helmet at the cable connection to realize the str...

Problems solved by technology

[0003] For the insulation layer of the cable, the insulation treatment can be realized as long as the insulation tape is applied, but the protection strength of the connection is not easy to achieve.

In addition, the most important shielding layer is very difficult to handle. Therefore, the current technology adopts the method of wearing a helmet at the cable connection to realize the strength of the cable joint and the processing of the shielding layer. It is convenient, and cannot achieve the shielding effect of the original cable, and the joint is easily affected by the outside world, which in turn affects the entire system, and sometimes even brings harm to the entire system
