Description

Technical Field

[0001] The utility model relates to the technical field of sheathed wires, in particular to a shielded sheathed wire. Background Art

[0002] In fact, the sheathed cable can be understood as two or three parallel BV wires. The BV wires originally have insulating rubber. A layer of rubber is wrapped around the three or two parallel BV wires. This layer of rubber is the sheathed cable. The sheathed cable is also one of the most commonly used household electrical wires, usually composed of three cores or two cores.

[0003] When two existing sheathed cables need to be connected, the wires in the two sheathed cables are often exposed, and then the different wires are wrapped together and covered with insulating tape to protect the wires. However, if only insulating tape is used for protection, the insulating tape will age over a long period of time, which may easily expose the wires, thereby causing certain safety hazards. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that the insulating adhesive tape is easily exposed after aging, thus causing certain safety hazards, and proposes a shielded sheathed wire.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a shielded sheathed cable, comprising a sheathed cable body, the outer surface wall of the sheathed cable body being provided with a protective component;

[0006] The protective assembly comprises a movable sleeve, and limiting rings are fixedly installed at both ends of the outer wall of the movable sleeve. The outer wall of the movable sleeve is threadedly connected with a rotating sleeve ring, and the outer wall of the rotating sleeve ring is fixedly installed with a protective sleeve.

[0007] Preferably, the inner wall diameter of the protective sleeve is larger than the diameter of the limiting ring.

[0008] Preferably, the sheathed cable body comprises a group of conductors, the outer walls of one group of the conductors are provided with an insulating layer, the outer walls of one group of the insulating layer are provided with a first shielding layer, and the outer walls of one group of the first shielding layer are provided with a filling layer.

[0009] Preferably, the inner wall of the filling layer is provided with a flexible filler, and the outer wall of the filling layer is provided with a second shielding layer.

[0010] Preferably, the outer wall of the second shielding layer is provided with a high temperature resistant layer, and the outer wall of the high temperature resistant layer is provided with a protective layer.

[0011] Preferably, the movable sleeve is arranged on the outer wall of the protective sleeve.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, when the wires in two sheathed wires are connected by winding and using insulating tape, in order to prevent the insulating tape from aging and being damaged, the movable sleeve can be slid to the vicinity of the connection between the sheathed wire bodies, and then the protective sleeve is rotated. During the rotation process, the protective sleeve drives the rotating sleeve ring to rotate on the surface of the movable sleeve, so that the protective sleeve is close to the connection between the wire and the insulating tape until the protective sleeve covers the insulating tape. At this time, the connection between the wires can be protected, the time for aging and damage of the insulating tape can be reduced, and direct contact with the exposed wires by the outside world can also be prevented.

[0014] 2. In the utility model, a first shielding layer and a second shielding layer are provided in the body of the sheathed cable, which effectively improves the electromagnetic shielding effect. At the same time, a filling layer is provided, and a flexible filler is provided in the filling layer. The flexible filler can increase the flexibility of the sheathed cable, making it easier to bend and arrange during installation, and is suitable for application scenarios that require frequent movement or bending. The high-temperature resistant layer can protect the sheathed cable or equipment from damage in a high-temperature environment. The protective layer can ensure that the sheathed cable is not corroded or damaged by the external environment, chemicals, ultraviolet rays, etc., and effectively protect the sheathed cable.
