Description

Technical Field

[0001] This utility model belongs to the field of power cable technology, and in particular relates to a wear-resistant coaxial cable. Background Technology

[0002] Radio frequency (RF) coaxial cables are cables with two concentric conductors, and the conductors and shielding layers share the same axis. The insulation material of RF coaxial cables consists of physically foamed polyethylene insulated copper wire conductors. Outside the inner insulation material is another ring-shaped conductor, the outer conductor. The outer conductor (which forms the shielding layer) is made of copper tape formed, welded, and corrugated; or it can be an aluminum tube structure; or it can be a braided structure. The entire cable is then covered by a sheath made of polyvinyl chloride (PVC).

[0003] Cables are often subjected to pulling during laying or transportation. During the pulling process, the outer layer of the cable is easily worn, causing damage to the cable. In addition, due to the large friction between the cable and the ground during pulling, it is also more difficult to pull. At the same time, the conductive copper wire is also easy to peel off from its outer sheath during pulling, resulting in low cable stability. To solve the above problems, a wear-resistant coaxial cable is provided.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this invention is to provide a wear-resistant coaxial cable. When the cable is placed on the ground, the rotating ball beneath the cable body contacts the ground, causing the ball to rotate within a spherical groove when the cable is dragged. This not only prevents wear on the outer sheath layer, thus avoiding impact on the cable's service life, but also reduces dragging force, saving manpower or mechanical power.

[0006] To achieve the above objectives, this utility model proposes an anti-wear coaxial cable, which includes a cable body and several protective components installed on the outer side of the cable body.

[0007] The protective component includes a fixing ring that is fixedly fitted around the cable body. The outer wall of the fixing ring has several spherical grooves, and rotating balls are installed in the spherical grooves.

[0008] Furthermore, the cable body includes, from the inside out, a conductive copper wire, a wrapping layer, a metal shielding layer, and an outer sheath.

[0009] Furthermore, the outer sheath is fixedly connected to the metal shielding layer.

[0010] Furthermore, several limiting strips are fixed on the outer side of the conductive copper wire.

[0011] Furthermore, the limiting strip is embedded in the inner wall of the wrapping layer.

[0012] Furthermore, the cable also includes a flame-retardant layer, which is located between the sheathing layer and the metal shielding layer.

[0013] Furthermore, the outer sheath has an outer wrapping layer on its outer side.

[0014] Furthermore, the limiting strip is bent.

[0015] The wear-resistant coaxial cable proposed in this utility model can bring the following beneficial effects:

[0016] 1. When the cable of this utility model is placed on the ground, the rotating ball under the cable body contacts the ground, so that when the cable is dragged, the rotating ball rotates in the spherical groove. On the one hand, it can avoid wear on the outer sheath layer, which affects the service life of the cable, and on the other hand, it can reduce the dragging force and save manpower or mechanical power.

[0017] 2. The cable of this utility model has several curved limiting strips on the outside of the conductive copper wire, and the limiting strips are embedded in the inner wall of the sheath layer, which can prevent the conductive copper wire from peeling off from the sheath layer when the cable is pulled, thereby improving the stability of the cable.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly.

[0027] An embodiment of this utility model provides an anti-wear coaxial cable, the cable including a cable body, and several protective components installed on the outside of the cable body.

[0028] like Figure 1As shown, the cable body includes, from the inside out, a conductive copper wire 6, a sheathing layer 5, a flame-retardant layer 4, a metal shielding layer 3, an outer sheath 2, and an outer wrapping layer 1, as follows: Figure 2 As shown, the outer sheath 2 is fixedly connected to the metal shielding layer 3.

[0029] The wrapping layer 5 is made of plastic, and the metal shielding layer 3 is made of mesh metal.

[0030] Several curved limiting strips 7 are fixed on the outside of the conductive copper wire 6. The limiting strips 7 are embedded in the inner wall of the wrapping layer 5, which can prevent the conductive copper wire 6 from peeling off from the wrapping layer 5.

[0031] The protective components include a retaining ring 8 that is fixedly fitted around the cable body, such as... Figure 2 As shown, the outer wall of the fixing ring 8 is provided with several spherical grooves 9, and a rotating ball 10 is installed in the spherical grooves 9.

[0032] When in use, when the cable is placed on the ground, the rotating ball 10 located below the cable body contacts the ground, so that when the cable is dragged, the rotating ball 10 located below rotates in the spherical groove 9. On the one hand, this can prevent the outer sheath layer 1 from being worn and affecting the service life of the cable, and on the other hand, it can reduce the dragging force and save manpower or mechanical power.
