Description

Technical Field

[0001] The utility model belongs to the technical field of electric wires and cables, and particularly relates to an anti-aging insulated sheathless electric wire and cable and a protective component. Background Art

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables, which can be defined as: a collection of the following parts; one or more insulated wire cores, and their respective coatings. Existing wires and cables are very susceptible to impact during transportation or wiring, but existing wires and cables cannot buffer the impact force well, which affects the service life of wires and cables. Therefore, an anti-aging insulated sheathless wire and cable and protective parts are proposed. Utility Model Content

[0003] The utility model aims to provide an anti-aging insulated sheathless wire and cable and a protective part. The support strip can be used to disperse the impact of the outer sheath to the inner sheath below, thereby dispersing the impact and increasing the service life of the cable. At the same time, a movable cover can be used to protect the cable end to avoid contamination of the cable end and excessive cable cutting during use, thereby solving the existing technical problems.

[0004] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0005] An anti-aging insulated sheathless wire and cable comprises: a plurality of conductors, the plurality of conductors are evenly distributed in a ring shape, the circumference of the conductors are all wrapped with an insulating layer, an inner protective layer is arranged outside the insulating layer, an outer protective layer is arranged around the circumference of the inner protective layer, a plurality of grooves are arranged on the circumferential inner wall of the outer protective layer, support bars are arranged in the grooves, the support bars are in the shape of an isosceles triangle and the bottom edge is in contact with the inner protective layer, and buffer holes are arranged through the support bars, and by installing the support bars inside the outer protective layer, the support bars can be used to disperse the impact of the outer protective layer to the inner protective layer below, thereby dispersing the impact and increasing the service life of the cable.

[0006] As a further solution of the utility model, a shielding layer is provided on the circumference of the insulating layer.

[0007] As a further solution of the utility model, a tensile rope is provided at the center of the inner protective layer.

[0008] As a further solution of the utility model, the circumferential outer wall of the outer protective layer is integrally formed with a plurality of raised convex points.

[0009] The utility model also proposes a protective part for protecting the ends of anti-aging insulated unsheathed wires and cables, comprising a sleeve and a movable cover, wherein the sleeve and the movable cover are plugged in, and the sleeve and the movable cover are both sleeved on one end of an outer sheath, and a gap is provided between the movable cover and the outer sheath, a pull ring is plugged in one end of the sleeve, and a conical sleeve for filling the gap is fixedly connected to one side of the pull ring, and at least two bidirectional screw rods are threadedly connected to one end of the sleeve, and the bidirectional screw rods are threaded through the movable cover and rotate to penetrate one end of the sleeve, and by installing the movable cover at the end of the cable, the cable end can be protected by the movable cover during transportation, so as to avoid contamination of the cable end and avoid excessive cable cuts during use.

[0010] As a further solution of the utility model, a gasket is bonded to one side of the movable cover.

[0011] In the utility model, when the cable is hit, especially the support bar is set in a triangular shape, so that the support bar can be used to disperse the impact of the outer sheath to the inner sheath below, thereby dispersing the impact and increasing the service life. The multiple protrusions on the surface of the outer sheath can increase the wear resistance of the outer sheath. When it is necessary to protect the cable end, the pull ring, the movable cover and the sleeve are set on the cable end, one end of the movable cover is pressed against the cable, and then the bidirectional screw rod is rotated. The bidirectional screw rod drives the pull ring and the conical sleeve to be inserted into the gap between the movable cover and the outer sheath, thereby completing the protection of the cable end and preventing the cable end from being contaminated.

[0012] The embodiments of the present invention have the following beneficial effects:

[0013] In the utility model, by installing a support bar inside the outer sheath, the support bar can be used to disperse the impact of the outer sheath to the inner sheath below, thereby dispersing the impact and increasing the service life of the cable;

[0014] In the utility model, by installing a movable cover at the end of the cable, the movable cover can be used to protect the end of the cable during transportation, thereby preventing the end of the cable from being contaminated and avoiding excessive cable cutting during use;

[0015] In the utility model, the support bar can be used to disperse the impact of the outer sheath to the inner sheath below, thereby dispersing the impact and increasing the service life of the cable. At the same time, the movable cover can be used to protect the cable end to avoid contamination of the cable end and excessive cable cutting during use.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
