Description

Technical Field

[0001] This utility model belongs to the technical field of dual-core conductors, specifically relating to a dual-core conductor with a protective structure. Background Technology

[0002] A two-core cable is a cable consisting of two insulated cores. It is mainly used in data transmission and signal transmission. Differential signal transmission is achieved through the two conductors, which can effectively reduce signal interference and improve transmission efficiency.

[0003] In existing dual-core conductors, under high-current conditions, the two cores are closely arranged, and the heat dissipation paths overlap, making it difficult for heat to dissipate quickly. This causes the insulation layer to be in a high-temperature environment for a long time, resulting in accelerated aging and even thermal breakdown. To address this, this invention proposes a dual-core conductor with a protective structure. Utility Model Content

[0004] The purpose of this invention is to provide a dual-core conductor with a protective structure to solve the problems mentioned in the background art, such as small core spacing, compressed space for heat radiation and air convection, and the common sheath blocking the independent heat dissipation channel of a single core, which makes it easy for heat to accumulate in the core gap.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-core conductor with a protective structure, comprising a dual-core conductor, wherein the dual-core conductor is composed of an outer sheath, a braided layer, an aluminum foil layer, a heat dissipation insulating strip, symmetrically arranged core wires, and symmetrically arranged cotton threads. The heat dissipation insulating strip is disposed between the symmetrically arranged core wires, and the symmetrically arranged cotton threads are disposed on both sides of the heat dissipation insulating strip. The aluminum foil layer wraps around the surfaces of the symmetrically arranged core wires, the symmetrically arranged cotton threads, and the heat dissipation insulating strip. The braided layer wraps around the surface of the aluminum foil layer, and the outer sheath is fitted onto the surface of the braided layer.

[0006] Preferably, the core wire is composed of copper wire and a high thermal conductivity insulation layer, with the copper wire penetrating the inner side of the high thermal conductivity insulation layer.

[0007] Preferably, grooves are provided on both sides of the heat dissipation isolation strip, and the surface of the high thermal conductivity insulation layer is in contact with the inner side of the groove.

[0008] Preferably, the heat dissipation isolation strip is composed of boron nitride ceramic and an aluminum foil blocking layer, wherein the aluminum foil blocking layer is disposed on the surface of the boron nitride ceramic.

[0009] Preferably, the area formed between the symmetrically arranged core wires, the symmetrically arranged cotton wires, the heat dissipation isolation strips, and the aluminum foil layer is filled with thermally conductive silicone grease.

[0010] Preferably, the inner side of the outer sheath is embedded with a copper-clad aluminum microwire woven mesh.

[0011] Preferably, the outer sheath has a thermally conductive filler added inside.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model of a dual-core conductor improves upon the problems of small spacing between symmetrically arranged cores, tight arrangement of the two cores, overlapping heat dissipation paths, and difficulty in rapid heat dissipation, which accelerates aging. Through a designed heat dissipation isolation strip, a high thermal conductivity insulation layer, thermally conductive filler, and an outer sheath, this combination efficiently dissipates heat using boron nitride ceramic, blocks heat radiation between cores using an aluminum foil blocking layer, eliminates contact thermal resistance using the thermally conductive filler, and protects the insulation layer. This solves the overheating problem caused by poor heat dissipation during high-current operation, as well as the resulting chain reaction of insulation aging, short-circuit risk, and shortened service life. Ultimately, it solves the overheating problem of dual-core conductors under high current, achieving the effects of reducing core operating temperature, delaying insulation aging, reducing short-circuit risk, and extending conductor service life. Simultaneously, it meets the basic performance requirements of conductors such as insulation and flexibility. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1 to 3This utility model provides a technical solution: a dual-core conductor with a protective structure, comprising a dual-core conductor 1, which is composed of an outer sheath 11, a braided layer 12, an aluminum foil layer 13, a heat dissipation insulating strip 14, symmetrically arranged core wires 15, and symmetrically arranged cotton threads 16. The heat dissipation insulating strip 14 is disposed between the symmetrically arranged core wires 15, and the symmetrically arranged cotton threads 16 are disposed on both sides of the heat dissipation insulating strip 14. The aluminum foil layer 13 wraps around the surfaces of the symmetrically arranged core wires 15, the symmetrically arranged cotton threads 16, and the heat dissipation insulating strip 14. The braided layer 12 wraps around the surface of the aluminum foil layer 13, and the outer sheath 11 is fitted onto the surface of the braided layer 12. This utility model provides a dual-core conductor with a protective structure. The core conductor 1 improves upon the previous dual-core conductor 1, which had a small spacing between the symmetrically arranged core wires 15, resulting in overlapping heat dissipation paths and difficulty in rapid heat dissipation, thus accelerating aging. This is achieved through a designed heat dissipation isolation strip 14, a high thermal conductivity insulation layer 152, thermally conductive filler, and an outer sheath 11. This combination utilizes boron nitride ceramic 141 for efficient heat conduction, aluminum foil blocking layer 142 to block heat radiation between core wires, thermally conductive filler to eliminate contact thermal resistance, and protect the insulation layer. This solves the overheating problem caused by poor heat dissipation during high-current operation, as well as the resulting chain reaction of insulation aging, short-circuit risk, and shortened service life, ultimately resolving the dual-core... The overheating problem of conductor 1 under high current is addressed by reducing the core wire's operating temperature, delaying insulation aging, reducing short-circuit risk, and extending conductor lifespan. It also meets the basic performance requirements of conductors, such as insulation and flexibility. The core wire 15 consists of copper wire 151 and a high thermal conductivity insulation layer 152. The copper wire 151 runs through the inner side of the high thermal conductivity insulation layer 152. The high thermal conductivity insulation layer 152 replaces PVC, allowing heat from the heat dissipation insulating strip 14 to pass through more quickly and reducing heat accumulation on its surface. Grooves 140 are provided on both sides of the heat dissipation insulating strip 14, and the surface of the high thermal conductivity insulation layer 152 is in close contact with the inner side of the grooves 140, effectively dissipating heat. The thermal isolation strip 14 is composed of boron nitride ceramic 141 and aluminum foil blocking layer 142. The aluminum foil blocking layer 142 is disposed on the surface of boron nitride ceramic 141. The boron nitride ceramic 141 increases the spacing between the core wires 15 and reduces heat conduction caused by physical contact. The aluminum foil blocking layer 142 blocks the heat radiation transfer between the core wires 15 and avoids the heat superposition effect. The area formed between the symmetrically arranged core wires 15, the symmetrically arranged cotton threads 16, the heat dissipation isolation strip 14 and the aluminum foil layer 13 is filled with thermally conductive silicone grease. Air is the heat insulation layer. The thermally conductive silicone grease eliminates the gap between the core wires 15 and the heat dissipation isolation strip 14. The silicone grease allows heat to be quickly conducted to the heat dissipation isolation strip 14 instead of accumulating in the gap.

[0016] In this embodiment, preferably, a copper-clad aluminum microfiber woven mesh 110 is embedded in the inner side of the outer sheath 11. The copper-clad aluminum microfiber woven mesh has a certain thermal conductivity, which can assist in heat conduction and quickly transfer internal heat to the surface of the outer sheath 11, increasing the heat dissipation area. Thermally conductive filler is added inside the outer sheath 11. The thermally conductive material is composed of graphene, aluminum powder, and boron nitride, which improves the thermal conductivity and accelerates the heat transfer to the surface of the outer sheath 11. The problem of "insufficient heat dissipation capacity of the outer sheath and difficulty in releasing heat to the environment" is solved by the outer sheath 11.

[0017] The working principle and usage process of this utility model are as follows: When installing the double-core conductor 1, first determine the purpose, clarifying whether the double-core conductor is used for power transmission or signal transmission, then assess the environment, considering the conductor's usage environment, including temperature, humidity, presence of corrosive gases or liquids, and whether it needs to withstand mechanical external forces, etc., and then calculate the parameters. For power transmission, calculate the required conductor cross-sectional area based on the load power and voltage to ensure that the conductor can safely carry current and avoid overheating. At the same time, determine the required voltage level and select a conductor with appropriate insulation strength. For signal transmission, select a conductor with appropriate characteristic impedance and shielding performance based on factors such as transmission distance and signal frequency, and select an appropriate conductor according to requirements. During the installation of the double-core conductor 1, lay the double-core conductor 1 according to the planned route using the prepared tools and accessories. After installation, perform insulation and continuity tests. When the dual-core conductor 1 generates heat through the flow of current, the heat is first transferred to the thermally conductive grease through contact. Since the thermally conductive grease can fill the tiny gap between the heat dissipation insulating strip 14 and the core wire 15, it eliminates the air insulation layer and solves the problem of poor air thermal conductivity, allowing the heat to be efficiently conducted to the heat dissipation insulating strip 14. The heat dissipation insulating strip 14, with its extremely high thermal conductivity, quickly conducts the heat out and disperses it into the surrounding space. The thermally conductive fillers such as graphene, aluminum powder, and boron nitride added to the outer sheath significantly improve the thermal conductivity of the sheath material, allowing the heat to diffuse more quickly in the outer sheath 11. At the same time, the copper-clad aluminum microfiber braided mesh 110 also has a certain thermal conductivity, which can help conduct heat to the surface of the sheath, increase the heat dissipation area, accelerate the dissipation of heat to the external environment, and ultimately reduce the overall temperature of the conductor, ensuring that it operates within a safe temperature range.
