Novel cable sheath

Abstract

The present invention discloses a novel cable sheath which comprises a plugging port, the right end of the plugging port is provided with a reinforcing ring, the right end of the plugging port is fixedly connected with the left end of the reinforcing ring, the inner ring of the reinforcing ring is provided with a rubber tube, and the inner ring of the reinforcing ring is fixedly connected with the outer surface of the rubber tube. An outer sheath ring is arranged in the rubber pipe, extrusion mechanisms are evenly arranged in the outer sheath ring, the inner wall of the outer sheath ring is fixedly connected with the top ends of the extrusion mechanisms, pressure reduction mechanisms are arranged at the bottom ends of the extrusion mechanisms, and the bottom ends of the extrusion mechanisms make contact with the top ends of the pressure reduction mechanisms. The novel cable sheath solves the problems that a cable buried underground is lack of certain protection, if the cable is not protected in place, the cable is difficult to maintain once the cable is damaged, the cable buried underground is often additionally provided with a sheath, but the existing cable sheath is general in protection effect and cannot effectively resist pressure, so that the service life of the cable is shortened.

Description

technical field [0001] The invention relates to the technical field of cable sheaths, in particular to a novel cable sheath. Background technique [0002] With the rapid development of our country's economy, power cables play an important role in our country's national economy. Now, in order to save space and avoid accidents, power cables are often buried underground, but the cables buried underground are lacking. Certain protection, if the protection is not in place, once damage occurs, it is difficult to repair the cable, and a sheath is often added to the cable buried underground, but the existing cable sheath has a general protective effect and cannot effectively resist pressure, resulting in In view of the reduction of the service life of the cable, it is urgent to carry out technical innovation on the basis of the existing cable sheath. A new type of cable sheath is proposed to solve the above-mentioned problems. Contents of the invention [0003] The purpose of the...

[0002] With the rapid development of our country's economy, power cables play an important role in our country's national economy. Now, in order to save space and avoid accidents, power cables are often buried underground, but the cables buried underground are lacking. Certain protection, if the protection is not in place, once damage occurs, it is difficult to repair the cable, and a sheath is often added to the cable buried underground, but the existing cable sheath has a general protective effect and cannot effectively resist pressure, resulting in The service life of the cable is reduced. In view of the above situation, it is urgent to carry out technological innovation on the basis of the existing cable sheath. A new type of cable sheath is proposed to solve the above-mentioned problems.
