[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0031] like Figure 1 As shown, this utility model discloses a preferred structure for a high-efficiency heat dissipation enhanced optoelectronic integrated cable.

[0032] like Figure 1 As shown, the high-efficiency heat-dissipating enhanced optoelectronic composite cable of this utility model includes a cable core, an inner sheath layer, a braided layer, and an outer sheath layer arranged sequentially from the inside out; the cable core includes an optical fiber core, multiple conductive cores, and at least one cooling pipe. The optical fiber core is located at the center of the cable core, and the multiple conductive cores and at least one cooling pipe are arranged around the optical fiber core.

[0033] The cable structure design of this utility model aims to enhance the heat dissipation capacity of the cable by incorporating cooling pipes, thereby reducing the cable's operating temperature, slowing down the aging of insulation and sheath materials, and extending the cable's service life. This addresses the issues of easy overload and accelerated aging in high-current-carrying-capacity applications.

[0034] By incorporating cooling pipes into the cable structure, the heat generated during operation can be effectively conducted to the heat dissipation cavity channels, achieving rapid diffusion. Furthermore, the optoelectronic composite cable can simultaneously transmit electrical energy, electrical signals, and optical signals, with no interference between the transmission lines. It also possesses excellent mechanical properties, a small outer diameter, light weight, quick and convenient use, and high cost-effectiveness.

[0035] In a specific implementation, the cooling pipe is hollow inside and is used for the flow of cooling medium. In one specific implementation, the cooling pipe may be a polyethylene composite pipe.

[0036] In a preferred embodiment, the inner sheath is made of polyether ether ketone material extruded and covered on the outer circumferential surface of the cable core. Polyether ether ketone (PEEK) has a high melting point (334℃) and glass transition temperature (143℃), and a continuous use temperature of 260℃; used to make the inner sheath, can meet the use requirements of the cable in high temperature environment. Polyether ether ketone has self-extinguishing property, even without any flame retardant, can reach UL standard 94V-0 level, the most optimal level of flame retardancy. To a certain extent, it can prevent the destruction of the cable by fire and ensure the demand for electricity.

[0037] In a preferred embodiment, the braided layer is a metal mesh structure formed by braiding tinned copper wire or tinned copper alloy wire, and the braiding density of the braided layer is not less than 70%.

[0038] The requirement of braiding density not less than 70% is to ensure that the cable has good shielding performance and anti-interference ability. The metal mesh structure can effectively provide electromagnetic interference (EMI) shielding to protect the signal transmission inside the cable from external electromagnetic field interference, while also reducing the electromagnetic radiation of the cable itself.

[0039] In a preferred embodiment, the outer sheath layer is made of thermoplastic elastomer material extruded and covered on the outer circumferential surface of the second water-blocking layer. In this technology, thermoplastic elastomer material (TPE) is used as the outer sheath layer, which has the characteristics of both plastic and rubber, and is known as the "third generation of synthetic rubber". The main function of the outer sheath layer is to improve the mechanical strength of the wire and cable and to provide protection for the internal structure.

[0040] In a preferred embodiment, the outer circumferential surface of the outer sheath layer is also provided with a wear-resistant layer, which is a black high-wear-resistant nylon sheath. The black high-wear-resistant nylon sheath has a lower friction coefficient than pure nylon resin, a higher PV value and better wear resistance, and better self-lubricating property. The wear-resistant nylon has more excellent wear resistance, heat resistance, oil resistance and corrosion resistance, and also greatly reduces the water absorption and shrinkage of the raw materials, has excellent dimensional stability and excellent strength, so that the product of the present technology has a longer service life and the sheath is not easy to be physically and mechanically damaged. According to the test method of wear resistance performance test in Appendix D of JB / T13795-2020 standard, the test results show that the product of the present technology needs 302,500 times to wear 1mm.

[0041] In a preferred embodiment, the gap of the cable core is also filled with a plurality of filling ropes, and the filling ropes are PP ropes.

[0042] In a preferred implementation, the filler rope of the cable core further comprises a plurality of reinforcing yarns, which are aramid yarn 3200 or aramid yarn 6320. As reinforcing yarns, aramid yarns can provide additional mechanical strength to the cable. The high tensile strength and low elongation of aramid yarns make them an ideal choice for cable reinforcing elements, especially in applications requiring high tensile strength.

[0043] In a specific implementation, with respect to the optical fiber core and the conductive core, both can be based on the existing technology. For example, the core structure described in CN206075901U, the optical fiber core and the conductive core do not belong to the core improvement of the present technology.

[0044] In a specific implementation, the conductive core comprises an inner conductor twisted by a plurality of tinned copper wires or tinned copper alloy wires and an extruded TPE insulation layer. The optical fiber core is armored by stainless steel on a nylon tight optical fiber.

[0045] Specifically, the number of conductive cores is more than 3, and the number of optical fiber cores is preferably 1-2.

[0046] In a preferred implementation, a first wrapping tape layer is provided between the inner sheath layer and the braided layer, and the first wrapping tape layer is calcined mica tape wrapped around the cable core.

[0047] A second wrapping tape layer is provided between the braided layer and the outer sheath layer, and the second wrapping tape layer is glass fiber tape wrapped around the first wrapping tape layer.

[0048] In the present technology, calcined mica tape is selected as the insulation material, and multiple layers of calcined mica tape are wrapped during cabling. Calcined mica tape is a composite material with extremely low combustion heat value. The use of calcined mica tape + glass fiber tape can meet the combustion heat value requirement of A-class combustion performance for materials. The multiple layers of calcined mica tape also prevent the broken fibers on the glass fiber tape from penetrating into the cable core insulation layer, causing the cable insulation resistance to decrease.

[0049] The other structures of the high-efficiency heat dissipation and reinforced optical-electric comprehensive cable described in the present embodiment refer to the existing technology.

[0050] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Any modification, equivalent change and modification of the above embodiment based on the technical essence of the present application still belongs to the scope of the technical solution of the present application.
