[0002] A wiring harness is a device that combines, packages, and bundles multiple wires or cables together. It can be used in electrical systems in electronic equipment, automobiles, aerospace, and other fields to provide functions such as power, signal transmission, and data transmission.

[0003] The existing heat dissipation wire harness (publication number: CN212782821U) includes a heat dissipation support frame, a wire core card mounting frame, a wire core, a wire harness connector male seat lower shell, a wire harness connector male seat upper shell, a wire harness connector female seat lower shell, a wire harness connector female seat upper shell, a wire harness sheath and a high temperature and heat resistant layer and an insulating layer. The overall structure is simple and has high temperature and heat resistance. It is suitable for protecting sealing, insulation, heat insulation, and moisture-proof protection in harsh environments. At the same time, it has a limit card mounting structure and a conductive heat dissipation structure, which is convenient for extending the service life of the wire harness, and is convenient for disassembly and assembly to produce the overall wire harness. It has high stability and practicality, and has certain promotion value. At least the following defects are exposed during use:

[0004] 1. During the use of the wiring harness, part of the electrical energy is converted into heat energy when the current is transported through the conductor, which increases the overall temperature of the wiring harness and easily causes the wiring harness to catch fire. However, the existing wiring harnesses often have poor heat dissipation or flame retardancy, so a wiring harness with high heat dissipation and flame retardant effect is now needed.

[0005] 2. Secondly, during the use of the wiring harness, due to power short circuit or other faults, the temperature of the wiring harness increases, and then a fire is caused. It is often necessary to wait until the fire occurs or the wiring harness burns inside and smokes outside before it is discovered by the outside world. However, it is too late at this time, which may easily cause loss of public property and threaten the life safety of passers-by. Therefore, a wiring harness with early warning is needed.

[0017] Preferably, a control switch is installed on the surface of the shell, and the control switch is electrically connected to the battery and the LED signal light and is connected to the temperature sensor signal.

[0018] The present invention provides a heat dissipation wiring harness having the following beneficial effects:

[0019] 1. By setting the heat absorption layer, the heat dissipation layer, the flame retardant layer and the thermal conductive filling chamber, the thermal conductive filling chamber can facilitate the rapid dissipation of the internal temperature of the wiring harness. The setting of the heat absorption layer can absorb the temperature from the thermal conductive filling chamber, and the setting of the heat dissipation layer can quickly dissipate the temperature to the outside, so that the internal ambient temperature of the wiring harness is stable.

DETAILED DESCRIPTION

[0027] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0028] Example: Figure 1 , Figure 2 as well as Figure 3 As shown, a heat dissipation type wiring harness includes a main body 1, the outermost side of the main body 1 is a protective layer 101, which is made of nylon. This material has good toughness and wear resistance, and can improve the service life of the wiring harness. The inner side of the protective layer 101 is a heat dissipation layer 102, which is made of artificial graphite heat dissipation film. This material has good heat dissipation performance and thermal radiation performance, and can quickly dissipate the internal temperature. The inner side of the heat dissipation layer 102 is a heat absorption layer 103, and the heat absorption layer 103 is filled with sodium silicate. This material has good heat absorption performance and can isolate the fire source when a fire occurs, thereby reducing the temperature of the burning object. The heat absorption layer 103 The inner side is a flame retardant layer 104, which is filled with phosphate flame retardant. The phosphate flame retardant has good flame retardant and thermal stability effects, and can effectively slow down the burning speed of the combustible and the spread of the flame. The inner side of the flame retardant layer 104 is an insulating layer 105, and the insulating layer 105 is made of polyvinyl chloride. This material has good insulation and heat resistance, and can prevent the insulating layer 105 from burning when the temperature of the wiring harness increases. Four heat-conducting filling chambers 8 are opened inside the main body 1, and the heat-conducting filling chambers 8 are filled with cured heat-conducting silicone. This material has good thermal conductivity and insulation properties, and can effectively transfer internal heat.

[0029] like Figure 1 , Figure 2 as well as Figure 4As shown, support rods 5 and wire cores 4 are installed inside the main body 1. The support rods 5 are distributed in an X shape and are used to support the internal structure. Each group of wire cores 4 is isolated by the support rods to avoid mutual interference of electrical signals between each group of wire cores 4. A group of temperature sensors 6 are arranged in the heat-conducting filling chamber 8 to sense the temperature change in the wire harness. A shell 11 is installed on the right side of the main body 1. The shell 11 is fixed to the surface of the main body 1 through a fixing rod 9 and a buckle 10. A battery 7 is installed inside the shell 11, and an LED signal light 3 and a control switch 2 are installed on the surface. The control switch 2 is used to control the on and off of the LED signal light 3. The LED signal light 3 serves to warn the outside world when the internal temperature of the wire harness reaches a set value.

[0030] Working principle: First, turn on the LED signal light 3 through the control switch 2. Under normal conditions, the LED signal light 3 is green. When the internal temperature of the wiring harness reaches the set temperature, the temperature sensor 6 transmits the signal to the control switch 2. The control switch 2 controls the LED signal light 3 to turn red, which is used to warn the outside world. When the wiring harness is working normally, the internal temperature can quickly pass through the heat-conducting filling chamber 8 and be absorbed by the heat absorption layer 103, and then dissipate to the outside world through the heat dissipation layer 102. When a fire occurs, after the insulating layer is burned, the phosphate flame retardant in the flame retardant layer 104 is released to prevent the spread of flames and slow down the burning speed of the flames. The sodium silicate filled in the heat absorption layer 103 can absorb the temperature inside the flame harness, reduce the temperature of the flame combustion and isolate the fire source, play a role in flame retardancy and heat absorption, and buy more time for subsequent fire extinguishing.

[0031] In this embodiment: the control circuit of the control switch 2 can be realized by simple programming by those skilled in the art, which is common knowledge in the art. It is only used without modification, so the control method and circuit connection will not be described in detail.

[0032] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
