[0024] In order to make the objects, features and advantages of the present application more obvious and understandable, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0025] The inventors analyzed the prior art and found that due to the limitation of the wire harness structure or processing technology, it is impossible to make a protective cover by extrusion or wrapping. Therefore, the cables or optical fibers can be made into an integral wire harness and then inserted into a pre-made cable-threading protective hose, and the hose can be used as a protective cover of the wire harness. Such a cable-threading protective hose can be cut into strips according to the needs and then threaded with cables, and can also be customized according to the customer's size requirements.

[0026] Reference Figure 1 , shows a high-strength cable-threading protective hose provided by an embodiment of the present application, comprising: a hose cover 4, a supporting cable and at least two groups of rope-shaped reinforcement members 1;

[0027] The rope-shaped reinforcement members 1 are interlaced and buried inside the wall of the hose cover 4, and the rope-shaped reinforcement members 1 are arranged around the axis of the hose cover 4;

[0028] The supporting cable is movably arranged on the inner side of the hose cover 4 along its axial direction.

[0029] In the embodiments of the present application, compared with the prior art in which the sheath cannot be set by extrusion or tape wrapping due to the limitation of part of the wire harness structure or processing technology, the present application provides a high-strength cable-threading protective hose, including: a hose cover 4, a support cable and at least 2 groups of rope-shaped reinforcements 1; the rope-shaped reinforcements 1 are interlaced and buried inside the wall of the hose cover 4, and the rope-shaped reinforcements 1 are arranged around the axis of the hose cover 4; the support cable is movably arranged on the inner side of the hose cover 4 along its axial direction. The present application solves the problem of wire protection for part of the wire harness that cannot be set by extrusion or tape wrapping. The high-strength cable-threading protective hose of the present application has a simple structure, is easy to process, and is easy to use. It can be customized to different specifications according to the size of the cable core to be threaded, and can be cut and used as needed.

[0030] Next, a high-strength cable-threading protective hose in this exemplary embodiment will be further described.

[0031] It should be noted that the at least two groups of rope-shaped reinforcement members 1 can be evenly distributed in an array along the outer periphery of the hose cover 4, so that the hose cover 4 is evenly stressed and has strong reusability. The support cable can ensure the process stability when the hose is extruded as a whole. When the hose is extruded, the support cable can play the role of the wall of the hose cover 4 to ensure that the hose as a whole can be extruded continuously and evenly. After the hose is formed, the support cable continues to remain inside the hose cover 4, and after rolling and packaging, the hose can be prevented from being deformed due to extrusion stress. When using the hose, the hose can be cut according to the length of use, and the internal support cable can be pulled out and inserted into the cable or optical fiber cable to be inserted. The support cable can also be used as a lead for the cable to be inserted.

[0032] In one embodiment of the present application, the hose cover 4 and the supporting cable are coaxial structures.

[0033] It should be noted that the coaxial structure ensures the uniformity of the hose wall and the roundness of the hose. When one side of the sheath is prone to wear or bending fatigue, the hose sheath 4 and the support cable can also be an eccentric shaft structure.

[0034] In one embodiment of the present application, the rope-shaped reinforcement member 1 includes at least two aramid filaments, and the rope-shaped reinforcement member 1 is formed by the aramid filaments being interlaced and twisted with each other.

[0035] It should be noted that the material of the aramid yarn can be a high-performance fiber yarn (KEVLAR), the main component of which is para-aromatic polyamide, which can increase the overall tensile strength and high temperature resistance of the hose.

[0036] In one embodiment of the present application, the support cable comprises an insulating layer 3 and a center lead 2;

[0037] The insulating layer 3 covers the central lead 2 .

[0038] It should be noted that the main function of the insulating layer 3 is to cover the central lead 2 to form a regular cylindrical object, support the inside of the protective hose and ensure that the inner wall of the hose is smooth and regular during extrusion. The main function of the central lead 2 is to ensure that the insulation 3 is not broken during extrusion, and after extrusion molding, it can play a tensile resistance role so that it is not easily broken during extraction.

[0039] In one embodiment of the present application, a gap is provided between the support cable and the hose cover 4 .

[0040] It should be noted that the gap between the support cable and the hose cover 4 can be a regular ring shape caused by the difference between the outer diameter of the support cable and the inner diameter of the hose cover 4, or can be other shapes set separately. The gap between the support cable and the hose cover 4 can ensure that the support cable can be easily pulled out before the cable is threaded. The inner wall of the support cable is set as a smooth surface to ensure that the support cable can be easily pulled out.

[0041] In one embodiment of the present application, the insulating layer 3 includes high-molecular high-temperature resistant fluoroplastic.

[0042] It should be noted that the main function of the polymer high temperature resistant fluoroplastic insulation is to ensure that the hose and the supporting cable do not stick together and have a certain degree of support.

[0043] In an embodiment of the present application, the center lead wire 2 includes at least one of aramid wire and alloy stranded wire.

[0044] In one embodiment of the present application, the hose cover 4 includes a high molecular thermoplastic elastomer.

[0045] It should be noted that the hose cover 4 is made of a polymer elastomer, which can quickly recover its original shape after being bent and stretched without affecting its mechanical properties.

[0046] In one embodiment of the present application, the hose cover 4 and the rope-shaped reinforcement member 1 are co-extruded to allow the rope-shaped reinforcement member 1 to be bonded to the hose cover 4 .

[0047] It should be noted that the hose cover 4 and the rope-shaped reinforcement member 1 are co-extruded, so that the rope-shaped reinforcement member 1 can be completely and evenly buried in the pipe wall and tightly bonded to the hose cover 4 to form a whole.

[0048] In one embodiment of the present application, the interlaced braiding pitch of the rope-shaped reinforcement members 1 is 8 mm; the interlaced braiding pitch of the aramid filaments is 5 mm.

[0049] It should be noted that the rope-shaped reinforcement member 1 can be a reinforcement member braided from four high-strength aramid yarns. The braiding process is: four aramid yarns, each with a structure of 130D, are first twisted rightward with a pitch of 5 mm to form the rope-shaped reinforcement member 1, and then the four groups of the rope-shaped reinforcement members 1 are braided again with a braiding pitch of 8 mm and evenly embedded in the hose cover 4 to improve the tensile performance.

[0050] In a specific embodiment of the present application, refer to Figure 1 A high-strength cable-threading protective hose of this embodiment includes: a hose cover 4, a supporting cable and 4 groups of rope-shaped reinforcement members 1; the rope-shaped reinforcement members 1 are interlaced and buried inside the wall of the hose cover 4, and the rope-shaped reinforcement members 1 are arranged around the axis of the hose cover 4; the supporting cable is movably arranged on the inner side of the hose cover 4 along its axial direction, and the hose cover 4 and the supporting cable are coaxial structures; the rope-shaped reinforcement member 1 includes at least 4 aramid filaments, and the aramid filaments are interlaced and self-twisted into shape.
