Problems solved by technology

[0004] Some of the current buried cables only use bottom plates, side plates and partitions to protect the cables. These methods are not good for the bearing capacity of the cables, and it is easy to cause damage to the cable core due to stress between the cables, and It is also troublesome to connect cables, which affects the use of buried cables

Abstract

The invention belongs to the technical field of shielding cables, and particularly relates to a buried high-temperature-resistant shielding cable which comprises a cable body and a connection seat, the cable body penetrates through the connection seat, a supporting seat is fixedly connected to the outer surface of the connection seat, and a shielding seat is fixedly connected to the interior of the supporting seat. A connection assembly is arranged on the side surface of the shielding seat, one side of the connection assembly is connected with a sealing assembly, the connection assembly comprises a poke rod rotationally connected with the side surface of the shielding seat, the outer surface of the poke rod is rotationally connected with a rotating rod, and one side of the rotating rod is connected with a push plate. When the rotating rod drives the push plate to move, the push plate can pull the telescopic rod and the extension spring on one side of the push plate at the same time, at the moment, the telescopic rod and the extension spring can reduce vertical loading force borne by the cable joint, the phenomenon that wires at the hinged position are damaged due to sudden stress of the cable joint is avoided, and the service life of the cable is prolonged.

Description

technical field [0001] The invention belongs to the technical field of shielded cables, in particular to a buried high temperature resistant shielded cable. Background technique [0002] The structure of the cable generally includes the outer protective layer of the cable and the core wire of the cable. In order to increase the safety of the core wire of the cable, some buried cables now require the outer layer of the cable to have better shear resistance and extrusion resistance. Especially direct buried cables. [0003] In order to ensure that the buried cable has better anti-shear and anti-extrusion capabilities, some solutions have also been proposed in the prior art. For example, a Chinese patent with publication number CN107979055A discloses a buried cable protection device, which includes Bottom plate; side plates located on both sides of the bottom plate, the side plates are supported by the bottom plate; mounting holes arranged on both sides of the side plate; The...
