Description

Technical Field

[0001] This utility model relates to the field of composite cable technology, specifically to a composite cable with a wear-resistant surface. Background Technology

[0002] Composite cables are cables with two or more cable units containing the same or different media. Composite cables play an important role in many fields such as power, communications, industrial automation, transportation and finance.

[0003] For example, Chinese patent CN221782979U discloses a cold-resistant and wear-resistant composite cable, including a cable body with a wear-resistant coating sprayed on the outside. The cable body includes a protective layer, with multiple cable cores disposed inside the protective layer, and multiple connecting posts integrally formed on the outside of the protective layer. A cold-resistant layer is integrally formed at one end of each connecting post, and a foam filling layer is disposed between the cold-resistant layer and the protective layer. Reinforcing ribs are embedded in the foam filling layer. The utility model increases the cold resistance of the cable by setting the cold-resistant layer and the foam filling layer, maintains the internal temperature of the cable, prevents the cable core from freezing, and improves the service life of the cable core.

[0004] While the aforementioned patent increases the cable's cold resistance, maintains the internal temperature of the cable, prevents the cable core from freezing, and improves the cable core's service life, the outermost layer of the composite cable in this patent has a single-layer abrasion-resistant coating. When the single-layer abrasion-resistant coating wears or falls off, the outer side of the composite cable is prone to wear, thereby reducing its abrasion resistance. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a composite cable with a wear-resistant surface, which has advantages such as improved wear resistance. It solves the problem that when the outermost layer of the composite cable is coated with a single layer of wear-resistant coating, the outer side of the composite cable is prone to wear when the single layer of wear-resistant coating is worn or peeled off, thus reducing the wear resistance.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wear-resistant composite cable, comprising a first insulation layer, a filler disposed inside the first insulation layer, at least two cable conductors disposed inside the first insulation layer, a second insulation layer disposed outside each of the at least two cable conductors, the filler being located outside the at least two second insulation layers, and a connecting component disposed outside the first insulation layer.

[0007] The connecting assembly includes a filling layer disposed outside the first insulating layer, a shielding layer disposed outside the filling layer, a heat insulation layer disposed outside the shielding layer, a heat insulation layer having at least two circular cavities through its front side, a reinforcing layer disposed outside the heat insulation layer, a wear-resistant layer disposed outside the reinforcing layer, and at least two wear-resistant strips disposed outside the wear-resistant layer.

[0008] Furthermore, both the first insulating layer and the second insulating layer are rubber layers.

[0009] Furthermore, the filler is silicone sealant.

[0010] Furthermore, the filling layer is a polypropylene layer, and the shielding layer is formed by wrapping beryllium copper flexible elastic sheets.

[0011] Furthermore, the heat insulation layer is a silicone rubber layer, and the reinforcing layer is made of double-layer galvanized steel strip.

[0012] Furthermore, the wear-resistant layer is a nylon layer, and the wear-resistant strip is a polytetrafluoroethylene (PTFE) strip.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This wear-resistant composite cable improves the insulation performance of individual conductors by providing a second insulation layer on the outer side of at least two conductors. A filler layer enhances the cable's heat resistance and tensile yield strength. A shielding layer improves the shielding effect, preventing external signal interference with the normal operation of the power cable. A heat insulation layer enhances the cable's heat insulation performance. Through the combined action of the wear-resistant layer and at least two wear-resistant strips, when the two wear-resistant strips wear down, the wear-resistant layer further protects the outer side of the cable, thus improving its wear resistance and overall protection performance and service life.
