Description

Technical Field

[0001] The utility model belongs to the technical field of connecting wires, and in particular relates to a heat-resistant connecting wire structure. Background Art

[0002] Connecting cables, also known as connecting cables or connecting wires, are essential carriers for data and power exchange. In circuits, they connect different electronic components or devices, enabling the flow of current and thus achieving the intended functionality of the circuit. With the advancement of technology, the importance of connecting cables in electronic products has become increasingly prominent. Their waterproof performance, signal transmission speed, and durability have become important criteria for measuring the quality of electronic products.

[0003] Announcement number "CN221040603U" discloses a heat-resistant electronic connecting wire. The wire body is provided with a first connector at one end and a second connector at the other end. Both the first connector and the second connector are in a flat shape. The wire body includes a heat-resistant layer and nine electronic wires disposed within the heat-resistant layer. The nine electronic wires are divided into two groups, which are secured to each other with double-sided tape. The first connector is provided with nine gold-plated terminals, which are respectively welded to the nine electronic wires. This utility model serves as an optimized structure, as an improved structure. Providing a heat-resistant layer on the wire body can improve the heat resistance of the electronic connecting wire. Furthermore, providing double-sided tape to secure the groups can improve stability.

[0004] Although the above-mentioned utility model provides a heat-resistant layer on the wire body to improve the heat resistance of the electronic connecting wire, and at the same time provides a double-sided tape fixation between the groups to improve stability, the heat resistance effect is poor if it relies solely on the heat-resistant layer. The high temperature environment will accelerate the aging process of the internal materials of the connecting wire, including the hardening of plastic and the corrosion of metal. These changes will shorten the service life of the connecting wire, increase the frequency and cost of replacement and maintenance, and high temperature will cause the performance of the connecting wire to decline and increase the risk of failure, resulting in the connecting wire may not be able to stably transmit signals or currents, thereby affecting the stability and reliability of the equipment. Utility Model Content

[0005] In response to the problems mentioned in the background technology, the purpose of the present invention is to provide a heat-resistant connecting wire structure to solve the problem that high temperature environment will accelerate the aging process of the internal materials of the connecting wire, including the hardening of plastic, corrosion of metal, etc. These changes will shorten the service life of the connecting wire and increase the frequency and cost of replacement and maintenance. In addition, high temperature will cause the performance of the connecting wire to decline and increase the risk of failure, resulting in the connecting wire may not be able to stably transmit signals or currents, thereby affecting the stability and reliability of the equipment.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A heat-resistant connecting wire structure includes a wire core body, a reinforcing core column and a protective inner sleeve. The outer wall of the reinforcing core column is symmetrically fixedly connected to a first support plate through an annular array, and the end of the first support plate away from the reinforcing core column is fixedly connected to the protective inner sleeve. The wire core and the first support plate are staggered. One end of the first support plate is symmetrically provided with a mounting groove, and a cooling plate is fixedly connected inside the mounting groove. A silicone filler is filled between the protective inner sleeve and the reinforcing core column. The wire core body is located inside the silicone filler. The outer wall of the protective inner sleeve is symmetrically fixedly connected to a second support plate through an annular array. The end of the second support plate away from the protective inner sleeve is fixedly connected to a protective outer sleeve. A heat-conducting gel filler is filled between the protective inner sleeve and the protective outer sleeve. The end is fixedly connected with a connector, and the cooling plate installed on the first support plate can quickly absorb and disperse the heat generated by the wire core, which helps to maintain a relatively low temperature environment around the wire core, reduce the thermal stress of the wire core caused by high temperature, and prevent the wire core from being damaged due to overheating. The silicone filler filled inside the protective inner sleeve can maintain the stability of the physical and chemical properties of the wire core in a high temperature environment, thereby enhancing the overall high temperature resistance of the connecting line. The thermal conductive gel filler filled between the protective outer sleeve and the protective inner sleeve can quickly conduct the heat generated inside the protective inner sleeve to the external environment, forming an efficient heat conduction channel, accelerating the dissipation of heat, and thus reducing the temperature of the connecting line.

[0008] As an optimal technical solution, the protective outer jacket includes a protective layer, a weather-resistant layer and a pressure-resistant layer. The outer layer of the pressure-resistant layer is fixedly connected to the protective layer, and the outer side of the protective layer is fixedly connected to the weather-resistant layer. The pressure-resistant layer is made of a glass fiber layer, the weather-resistant layer is made of a polyurethane layer, and the protective layer is made of a polyvinyl chloride layer. The protective layer can effectively resist external mechanical impact, wear and extrusion, protect the internal protective inner sleeve or the wire core body from damage, and prevent the cable from being corroded by acids, alkalis and other chemical substances. The weather-resistant layer can resist long-term exposure to ultraviolet rays, prevent the performance of the connecting line from degrading due to ultraviolet aging, and prevent the connecting line from cracking or deformation due to temperature changes. The pressure-resistant layer can increase the pressure resistance, bending resistance and impact resistance of the connecting line, making the connecting line less likely to be damaged when subjected to external forces.

[0009] As an optimal technical solution, the protective inner sleeve includes a shielding layer, an insulating layer and a heat-resistant layer. The insulating layer is fixedly connected to the outside of the shielding layer, and the heat-resistant layer is fixedly connected to the outside of the insulating layer. The shielding layer is made of a metal foil layer, the insulating layer is made of a polypropylene layer, and the heat-resistant layer is made of a fluoroplastic layer. The shielding layer can effectively block the interference of external electromagnetic waves, ensure the accuracy and stability of signal transmission, and prevent static charge from accumulating on the surface of the insulating layer, thereby avoiding the harm of electrostatic discharge to equipment and personnel. The heat-resistant layer can resist the damage to the connecting wire caused by high temperature environment, ensure that the connecting wire can still work normally at high temperature, and prevent high temperature from damaging the internal material of the connecting wire, thereby extending the service life of the connecting wire. The insulating layer can ensure electrical insulation between the conductor and the surrounding environment or adjacent conductors, prevent current leakage and short circuit, and ensure personal and equipment safety.

[0010] As an optimal technical solution, the outer wall of the protective jacket is symmetrically fixedly connected with a flame-retardant bulge through a circular array, and the flame-retardant bulge is filled with mineral fillers. The flame-retardant bulge can provide additional fire protection. When the connecting line encounters a fire source, the flame-retardant bulge can slow down the spread of the flame. The flame-retardant bulge can also isolate external heat to a certain extent to prevent the connecting line from being damaged by external high temperature. The mineral filler inside the flame-retardant bulge has high temperature resistance and flame retardant properties, which can effectively prevent the spread of fire.

[0011] As an optimal technical solution, a receiving groove is opened at one end of the reinforced core column, and a cooling column is fixedly connected to the inside of the receiving groove. The cooling column is made of ceramic material, and the cooling plate is made of polymer ice crystal gel material. It can effectively absorb and disperse the heat generated by the connecting wire during the current transmission process, which helps to maintain the connecting wire at a lower operating temperature and reduce the risk of performance degradation or damage due to high temperature.

[0012] In summary, the present invention has the following beneficial effects:

[0013] In the present invention, the cooling plate installed on the first support plate can quickly absorb and disperse the heat generated by the wire core, thereby effectively reducing the temperature generated by the wire core during operation. Moreover, by continuously absorbing and dispersing heat, it helps to maintain a relatively low temperature environment around the wire core, which can reduce the thermal stress generated by the wire core due to high temperature and prevent the wire core from being damaged due to overheating. The silicone filler filled inside the protective inner sleeve can maintain the stability of the physical and chemical properties of the wire core in a high temperature environment, thereby enhancing the overall high temperature resistance of the connecting wire, and at the same time prevent current leakage and short circuit, especially under high temperature conditions, it can still maintain a good insulation effect. The thermal conductive gel filler filled between the protective outer sleeve and the protective inner sleeve can quickly conduct the heat generated inside the protective inner sleeve to the external environment, forming an efficient heat conduction channel, accelerating the dissipation of heat, thereby reducing the temperature of the connecting wire, and filling the tiny gap between the protective inner sleeve and the outer sleeve, reducing the presence of poor heat conductors such as air, thereby reducing thermal resistance and improving heat conduction efficiency.
