Description

Technical Field

[0001] This utility model relates to wire and cable technology, specifically to a type of overhead wire that can be used for mobile installation. Background Technology

[0002] Electrical wiring is mainly used for power distribution and connection within buildings or equipment. With the rapid development of industrial automation, temporary power supply at construction sites, stage lighting equipment, mobile robots, and other fields, mobile installation scenarios have placed higher demands on the performance of electrical wiring. In such scenarios, the wires need to be frequently bent, dragged, quickly installed and dismantled, and exposed to complex environments for a long time, such as high temperature, low temperature, humidity, and oil. Traditional electrical wiring designs were mostly intended for fixed installation scenarios, such as building power distribution and household appliances, and their material selection and structural design are difficult to meet the special needs of mobile scenarios.

[0003] However, existing overhead cables lack flexibility and fatigue resistance during use. During the laying of cables, frequent bending and dragging operations are required, which subject the cables to various stresses such as twisting, stretching, and bending. This stress concentration can easily lead to fatigue fracture of the cables, causing power outages or short circuits and causing considerable inconvenience to users. Utility Model Content

[0004] The purpose of this invention is to provide a mobile cable that can be used for laying cables to solve the problem that in the prior art, the frequent bending and dragging operations required during the laying of cables cause the cables to be subjected to various stresses such as twisting, stretching and bending, which can easily lead to fatigue fracture of the cables due to stress concentration, resulting in power outages or short circuits and causing a lot of inconvenience to users.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mobile laying cable, comprising an outer sheath assembly and a reinforcing assembly wrapped inside the outer sheath assembly, and an inner sheath assembly assembled inside the reinforcing assembly. The outer sheath assembly includes a wear-resistant outer sheath layer, an anti-cutting layer wrapped inside the wear-resistant outer sheath layer, a flame-retardant layer wrapped inside the anti-cutting layer, a waterproof layer wrapped inside the flame-retardant layer, and a first braided layer wrapped inside the waterproof layer.

[0006] The reinforcing component includes an anti-torsion sleeve wrapped inside the first braided layer, with a first reinforcing rib inlaid on the periphery of the anti-torsion sleeve and a second reinforcing rib inlaid on the inner wall of the anti-torsion sleeve.

[0007] The inner protective assembly includes an isolation layer wrapped around the inner wall of the anti-torsion sleeve, a second braided layer wrapped inside the isolation layer, an insulation layer wrapped inside the second braided layer, a shielding layer wrapped inside the insulation layer, and a wire core wrapped inside the shielding layer.

[0008] Furthermore, the wear-resistant outer protective layer is made of polyurethane material, and the cut-resistant layer is a metal armor layer made of galvanized steel strip.

[0009] Furthermore, the flame-retardant layer is made of polyvinyl chloride, and the waterproof layer is made of high-density polyethylene.

[0010] Furthermore, the first braided layer is woven from Kevlar fiber material, and the anti-torsion sleeve has through holes inside, which are arranged in a ring array.

[0011] Furthermore, an outer protective layer is wrapped between the anti-torsion sleeve and the first braided layer, and an inner protective layer is wrapped between the anti-torsion sleeve and the isolation layer. Both the outer protective layer and the inner protective layer are made of polyethylene material.

[0012] Furthermore, the outer periphery of the anti-torsion sleeve is provided with a first limiting groove for the first reinforcing rib to be inserted, and the inner wall of the anti-torsion sleeve is provided with a second limiting groove for the second reinforcing rib to be inserted.

[0013] Furthermore, the isolation layer and the second woven layer are bonded and fixed together by a first adhesive layer, and the second woven layer is made of chemically synthesized fiber material.

[0014] Furthermore, the second braided layer and the insulating layer are bonded and fixed together by a second adhesive layer. The insulating layer is made of epoxy resin material, and the shielding layer is made of carbon black-filled polymer material.

[0015] Compared with the prior art, the present invention provides a mobile laying cable that, by incorporating reinforcing components, effectively improves the cable's torsion resistance using an anti-torsion sleeve. During mobile laying, it reduces cable torsion and prevents excessive torsion that could cause cracks in the insulation. Furthermore, the first and second reinforcing ribs enhance structural strength, improving the cable's bending resistance and preventing fatigue fractures caused by frequent bending, thus improving overall performance.

[0016] By combining the first and second braided layers, a double tensile strength effect can be achieved, which can effectively resist the dragging and stretching of the wire during mobile installation. This prevents the wire from being deformed and elongated due to tensile force, and avoids the possibility of cracking of the internal protective layers due to wire deformation. It can effectively protect the wire from various stresses such as twisting, stretching, and bending, which can lead to breakage and bring more convenience to users. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] As attached Figure 1 To be continued Figure 5 As shown:

[0027] Example 1:

[0028] This utility model provides a building cable that can be used for mobile installation, including an outer sheath component 1 and a reinforcing component 2 wrapped inside the outer sheath component 1, and an inner sheath component 3 assembled inside the reinforcing component 2. The outer sheath component 1 includes a wear-resistant outer sheath layer 11, a cut-resistant layer 12 wrapped inside the wear-resistant outer sheath layer 11, a flame-retardant layer 13 wrapped inside the cut-resistant layer 12, a waterproof layer 14 wrapped inside the flame-retardant layer 13, and a first braided layer 15 wrapped inside the waterproof layer 14.

[0029] The reinforcing component 2 includes an anti-torsion sleeve 23 wrapped inside the first braided layer 15. A first reinforcing rib 24 is inlaid on the periphery of the anti-torsion sleeve 23, and a second reinforcing rib 25 is inlaid on the inner wall of the anti-torsion sleeve 23.

[0030] The inner protective component 3 includes an isolation layer 31 wrapped around the inner wall of the anti-torsion sleeve 23. The isolation layer 31 is wrapped with a second braided layer 33. The second braided layer 33 is wrapped with an insulation layer 35. The insulation layer 35 is wrapped with a shielding layer 36. The shielding layer 36 is wrapped with a wire core 37.

[0031] As can be seen from the above, the outermost wear-resistant outer sheath 11 of the outer sheath component 1 can effectively resist the friction between the wire and the object during the moving and laying process, which can reduce the scratches caused by friction and protect the internal structure from damage. The anti-cut layer 12 can enhance the anti-cut ability and is less likely to be cut when encountering relatively sharp objects, which can effectively strengthen the physical protection effect and bring more convenience to the moving and laying of wires. The flame-retardant layer 13 can block the combustion of flames, which can effectively reduce the occurrence of fires, and can resist the high temperature of external fires to avoid losses caused by combustion. The waterproof layer 14 can be used outdoors and in humid environments, which can prevent moisture from penetrating into the interior and causing short circuits. The first braided layer 15 can improve the tensile strength of the outer sheath component 1 and can prevent the breakage caused by stretching during dragging.

[0032] The anti-torsion sleeve 23 can effectively improve the torsion resistance of the wire. During the moving and laying process, it can reduce the torsion of the wire and avoid the situation where the wire is cracked due to excessive torsion. At the same time, the first reinforcing rib 24 is distributed on the outer periphery of the anti-torsion sleeve 23, and the second reinforcing rib 25 is distributed on the inner wall of the anti-torsion sleeve 23, which can form a double-layer reinforcement effect, effectively improving the structural strength, enabling the wire to have a strong bending resistance, effectively avoiding fatigue fracture of the wire due to frequent bending, and improving the service performance.

[0033] The isolation layer 31 isolates the reinforcing component 2 from the inner protective component 3, allowing the reinforcing component 2 to protect the internal power transmission operation of the inner protective component 3 from interference. The second braided layer 33, together with the first braided layer 15, forms a double tensile resistance effect, effectively resisting the dragging and stretching of the wire during mobile installation. This prevents the wire from being deformed and elongated due to tensile forces, avoiding the possibility of the internal protective layers breaking due to wire deformation. It effectively protects the wire from various stresses such as twisting, stretching, and bending, thus providing greater convenience for use. The insulation layer 35 insulates the wire core 37 during power transmission, preventing leakage. The shielding layer 36 protects the wire core 37 from interference from external factors during power transmission and prevents electromagnetic interference generated during power transmission from being transmitted to the external environment, improving safety during use.

[0034] From the appendix Figure 2 It is known that the wear-resistant outer protective layer 11 is made of polyurethane material, and the cut-resistant layer 12 is a metal armor layer made of galvanized steel strip.

[0035] As can be seen from the above, the wear-resistant outer protective layer 11 made of polyurethane material has excellent wear resistance, oil resistance and cold resistance. At the same time, the wear-resistant outer protective layer 11 is coated with a ceramic particle coating, which can effectively improve the wear resistance. During the mobile laying process, it can reduce the friction and wear between the outer protective layer and the object, and reduce the possibility of scratches and cracks. The metal armor layer made of galvanized steel strip forms a cut-resistant layer 12, which can effectively improve mechanical stress and effectively resist the cutting of sharp objects, avoiding the possibility of puncture and breakage caused by sharp objects.

[0036] For details, please refer to the appendix. Figure 2 As shown, the flame-retardant layer 13 is made of polyvinyl chloride, and the waterproof layer 14 is made of high-density polyethylene.

[0037] As can be seen from the above, the flame-retardant layer 13 made of polyvinyl chloride can suppress the spread of fire when burning, which can effectively prevent the occurrence of fire. The waterproof layer 14 made of high-density polyethylene can prevent water molecules from penetrating by utilizing its physical barrier properties, which allows the wires to be used outdoors and in humid environments.

[0038] For details, please refer to the appendix. Figure 2 As shown, the first braided layer 15 is woven from Kevlar fiber material, and the anti-torsion sleeve 23 has through holes 27 inside, which are arranged in a ring array.

[0039] As can be seen from the above, the first braided layer 15, which is made of Kevlar fiber material, can improve the mechanical strength and durability of the wire and prevent deformation and breakage caused by stretching during moving and laying.

[0040] Working principle: The wear-resistant outer sheath 11 in the outer sheath component 1 can improve wear resistance during mobile installation. The cut-resistant layer 12 can resist puncture by sharp objects. The flame-retardant layer 13 can prevent combustion in a fire. The waterproof layer 14 can prevent water penetration and can be used stably in outdoor and humid environments. The first braided layer 15 can improve the tensile strength of the wire and prevent deformation and elongation caused by dragging. The first reinforcing rib 24 and the second reinforcing rib 25 can improve the structural strength of the anti-torsion sleeve 23, so that the anti-torsion sleeve 23 can effectively resist the torsion caused during mobile installation and protect the wire from deformation and breakage caused by torsion. The second braided layer 33 can achieve a double tensile effect and effectively enhance the tensile strength. The insulation layer 35 can prevent leakage. The shielding layer 36 can isolate electromagnetic interference from the external environment and prevent interference with power transmission operation.

[0041] Example 2:

[0042] Reference Appendix Figure 3 As shown, an outer protective layer 21 is wrapped between the anti-torsion sleeve 23 and the first braided layer 15, and an inner protective layer 29 is wrapped between the anti-torsion sleeve 23 and the isolation layer 31. Both the outer protective layer 21 and the inner protective layer 29 are made of polyethylene material.

[0043] As can be seen from the above, the outer protective layer 21 and the inner protective layer 29 made of polyethylene material can easily wrap the outer and inner walls of the anti-torsion sleeve 23, which can prevent the first reinforcing rib 24 and the second reinforcing rib 25 from detaching.

[0044] Reference Appendix Figure 4 As shown, the outer periphery of the anti-torsion sleeve 23 is provided with a first limiting groove 26 for the first reinforcing rib 24 to be inserted, and the inner wall of the anti-torsion sleeve 23 is provided with a second limiting groove 28 for the second reinforcing rib 25 to be inserted.

[0045] As can be seen from the above, the first limiting groove 26 can conveniently limit the first reinforcing rib 24 to prevent displacement, and the second limiting groove 28 can limit the second reinforcing rib 25 to prevent displacement.

[0046] Reference Appendix Figure 5 As shown, the isolation layer 31 and the second braided layer 33 are bonded and fixed together by the first adhesive layer 32, and the second braided layer 33 is made of chemically synthesized fiber material.

[0047] As can be seen from the above, the first adhesive layer 32 can conveniently fix the isolation layer 31 and the second braided layer 33, which can avoid displacement and gaps when twisting and bending. The fiber is made by using chemically synthesized polymers as raw materials and processed by chemical and physical methods. The second braided layer 33 can effectively enhance the tensile strength.

[0048] Reference Appendix Figure 5 As shown, the second braided layer 33 and the insulating layer 35 are bonded and fixed together by the second adhesive layer 34. The insulating layer 35 is made of epoxy resin material, and the shielding layer 36 is made of carbon black filled polymer material.

[0049] As can be seen from the above, the second adhesive layer 34 can fix the insulating layer 35 and the second braided layer 33 together. The insulating layer 35, made of epoxy resin, has a good insulating effect. The shielding layer 36, made of carbon black-filled polymer material, controls the volume resistivity to 10 Ω·cm. 3 -10 6 Ω·m, which can prevent partial discharge.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
