Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of power wiring harnesses, and in particular relates to an automobile power wiring harness and a preparation process thereof. Background Art
[0002] The automotive power harness is an integrated system composed of components such as wires, connectors, insulation / wrapping materials, and is responsible for the core functions of vehicle power transmission, signal control, and data interaction.
[0003] During long-term use in a car, it will be affected by high temperatures. For example, poor contact of connectors, short circuit or grounding of wires, size mismatch, terminal corrosion, wiring harness aging, high ambient temperature, circuit overload, improper fixation and improper modification, etc., all have the probability of causing the power harness to heat up or even burn, affecting the safety of the vehicle's electrical system.
[0004] When repairing or replacing the automotive power harness, the damaged part can be repaired according to the test results, and only a part of the harness can be stripped off. It is usually used to repair or replace a single damaged harness segment. For example, in car repair, if the plug of the harness is damaged, only the plug can be replaced without replacing the entire harness. Partial replacement is usually less expensive because only the damaged part needs to be replaced, while the entire replacement requires the purchase of a new harness assembly, which is more expensive.
[0005] Automobile power wiring harnesses will inevitably generate high temperatures when in a faulty state, but the risks can be controlled through material selection and standardized maintenance. Partial stripping is allowed during maintenance, but the process must be strictly selected according to the damage type.
[0006] At present, there are many reasons for high temperature of wiring harness. Most of them are judged by damage to the appearance, such as local overheating and carbonization, to determine whether the power wiring harness is affected by high temperature and whether to strip off the section for repair. However, this method requires obvious damage to the appearance of the wiring harness. When there is no obvious damage to the appearance, especially when there is no obvious problem with the vehicle, it is easy for the staff to neglect the inspection of the wiring harness, and it is impossible to judge whether the wiring harness has been subjected to high temperature. Once the section of the wiring harness that has been subjected to high temperature is not repaired, it is easy to have secondary high temperature, and the risk of fire will increase accordingly. There are certain hidden dangers. At the same time, it is difficult for the driver to find the problem of high temperature of the wiring harness while driving. Most of the time, the fire will be extinguished only after the high temperature catches fire, or even the car will be abandoned and fled. The safety of the driver is not guaranteed, and the economic loss is relatively serious.
[0007] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

DETAILED DESCRIPTION
[0039] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.
[0040] like Figures 1 to 8 As shown, an automotive power harness according to one embodiment of the present invention includes: a power harness body 1, a thermal insulation lifting mechanism 2, a warning device 3, and a positioning and mounting mechanism 4. The power harness body 1 is used to connect to the vehicle circuit. The thermal insulation lifting mechanism 2 is disposed on the outside of the power harness body 1 and includes a thermal insulation and heat conduction mechanism 21, a thermal conduction lifting mechanism 22, and a coolant. The thermal insulation and heat conduction mechanism 21 is disposed on the upper side of the power harness body 1 and contacts the power harness body 1. It absorbs heat from the power harness body 1 and conducts it to the coolant. The coolant is disposed within the thermal insulation and heat conduction mechanism 21 and vaporizes the heat. The thermal conduction lifting mechanism 22 is slidably mounted within the thermal insulation and heat conduction mechanism 21 and is configured to rise through the vaporization of the coolant. The warning device 3 includes a trigger button 31 fixedly mounted within the thermal insulation and heat conduction mechanism 21 and a buzzer 32 fixedly mounted on the upper side of the thermal insulation and heat conduction mechanism 21. The trigger button 31 is configured to activate the buzzer 32 upon triggering. The buzzer 32 is configured to alert the driver. The positioning and mounting mechanism 4 is mounted on the upper side of the heat insulating and heat conducting mechanism 21 and is used to fix the position of the heat conducting lifting mechanism 22 .
[0041] The method of using the automobile power harness is as follows: the power harness body 1 is fixed by the heat-insulating heat-conducting mechanism 21. When the temperature of the power harness body 1 rises, the coolant will be heated by the heat-insulating heat-conducting mechanism 21, so that the coolant can be vaporized and the volume can expand. The expansion of the coolant volume can lift the heat-conducting lifting mechanism 22. When the power harness body 1 is overheated, the volume of the coolant will expand to a certain extent, and the heat-conducting lifting mechanism 22 will rise until the trigger button 31 is triggered. When it is not under maintenance, the buzzer 32 can sound an alarm to remind the driver. When maintenance is in progress, it can be judged by the rising amplitude of the heat-conducting lifting mechanism 22. At the same time, the positioning and mounting mechanism 4 can jam the heat-conducting lifting mechanism 22. When overheating is not discovered, it can also be discovered during subsequent maintenance to avoid hidden dangers that cannot be discovered.
[0042] like Figures 1 to 8 As shown, the heat-insulating and heat-conducting mechanism 21 includes: a heat-insulating and heat-conducting chamber 211, a clamping heat-conducting plate 212, a heat-isolating uniform plate 213, and a heat-insulating clamping plate 214. The heat-insulating and heat-conducting chamber 211 is arranged on the upper side of the power harness body 1, the heat-isolating and heat-conducting plate 212 is fixedly mounted on the lower side of the heat-insulating and heat-conducting chamber 211 and contacts the power harness body 1, the heat-isolating uniform plate 213 is fixedly mounted on the upper side of the clamping heat-conducting plate 212 and passes through the heat-insulating and heat-conducting chamber 211, and the heat-insulating clamping plate 214 is arranged on the lower side of the power harness body 1 and cooperates with the clamping heat-conducting plate 212 by bolt connection to clamp the power harness body 1.
[0043] Among them, the heat-insulating heat-conducting chamber 211 can accommodate coolant, reducing the leakage of coolant, and the clamping heat-conducting plate 212 can absorb the heat on the power harness body 1, and conduct the heat on the power harness body 1 to the heat-insulating uniform plate 213. At the same time, it can cooperate with the heat-insulating clamping plate 214 to clamp the power harness body 1, so that the position of the heat-insulating heat-conducting mechanism 21 is fixed.
[0044] In addition, the heat of the clamping heat conducting plate 212 can be absorbed and transferred to the coolant to heat the coolant and vaporize the coolant. The clamping heat conducting plate 212 can be fixed to the clamping heat conducting plate 212 by bolts, and the clamping effect of the power harness body 1 can be controlled by the tightness of the bolts.
[0045] like Figures 1 to 6 As shown, an insulating vacuum plate 215 is fixedly installed on the outside of the insulating heat-conducting chamber 211, and multiple insulating uniform plates 213 are provided. The multiple insulating uniform plates 213 are evenly distributed, and the clamping heat-conducting plate 212 and the insulating clamping plate 214 are both matched with the power harness body 1.
[0046] Among them, the thermal insulation vacuum plate 215 can isolate the surrounding temperature, reduce the impact of the surrounding temperature on the coolant, and improve the accuracy of coolant gasification. The thermal insulation uniform plate 213 can continuously heat the coolant, which can improve the heating efficiency of the coolant.
[0047] like Figures 1 to 4 As shown, the heat-conducting lifting mechanism 22 includes a lifting power plate 221, a pair of lifting gear plates 222, and a lifting balance rod 223. The lifting power plate 221 is slidably mounted within the heat-insulating heat-conducting chamber 211. The pair of lifting gear plates 222 are fixedly mounted on the lifting power plate 221. The pair of lifting balance rods 223 are fixedly mounted on the underside of the lifting power plate 221 and extend through the heat-insulating heat-conducting chamber 211.
[0048] The lifting power plate 221 can be squeezed by the gasified coolant to rise, and can drive the lifting gear plate 222 to rise, so that the lifting gear plate 222 rises.
[0049] In addition, the lifting gear plate 222 can be driven by the lifting power plate 221, can be lifted, can be engaged, and can remind maintenance personnel of the maximum temperature of the power harness body 1 during operation.
[0050] In addition, the lifting balance bar 223 can improve the balance of the lifting power plate 221, reduce the probability of the lifting power plate 221 tilting, reduce the probability of the lifting power plate 221 shaking, and improve the stability of the lifting power plate 221.
[0051] like Figures 1 to 4 As shown, the coolant is arranged between the lifting power plate 221 and the heat-insulating heat-conducting chamber 211, and the coolant is arranged on the lower side of the lifting power plate 221. A lifting sealing ring 224 is fixedly installed on the outside of the lifting power plate 221, which can improve the sealing between the lifting power plate 221 and the heat-insulating heat-conducting chamber 211. The lifting sealing ring 224 matches the heat-insulating heat-conducting chamber 211, which reduces the possibility of coolant leakage and improves the service life of the coolant. The lifting gear plate 222 is set through the heat-insulating heat-conducting chamber 211 and the heat-insulating vacuum plate 215.
[0052] like Figures 1 to 5 As shown, a pair of lifting gear plates 222 are fixedly installed with prompt color blocks on the side away from each other, which can remind maintenance personnel and enable them to check the maximum temperature of the power harness body 1. A sealing ring 225 is installed between the lifting balance rod 223 and the thermal insulation and heat conduction chamber 211, which can improve the sealing between the lifting balance rod 223 and the thermal insulation and heat conduction chamber 211, reduce the possibility of coolant leakage in the thermal insulation and heat conduction chamber 211, and at the same time do not affect the sliding of the lifting balance rod 223.
[0053] like Figures 1 to 3As shown, the positioning and mounting mechanism 4 includes a pair of positioning and mounting shafts 41, a positioning tooth plate 42, and a positioning spring 43. The pair of positioning and mounting shafts 41 are fixedly mounted on the thermal insulation vacuum plate 215. The pair of positioning tooth plates 42 are slidably mounted on the pair of positioning and mounting shafts 41. The pair of positioning springs 43 are sleeved on the positioning and mounting shafts 41.
[0054] Among them, the positioning mounting shaft 41 improves the stability of the positioning tooth plate 42, reduces the probability of the positioning tooth plate 42 being disengaged, makes the sliding of the positioning tooth plate 42 more stable, and enables the positioning tooth plate 42 to better engage with the lifting tooth plate 222. The positioning tooth plate 42 can engage with the lifting tooth plate 222, reducing the probability of the lifting tooth plate 222 being disengaged, and the rising position of the lifting tooth plate 222 can be fixed. The positioning spring 43 can squeeze a pair of positioning tooth plates 42, so that a pair of positioning tooth plates 42 engage with the lifting tooth plate 222.
[0055] like Figures 1 to 6 As shown, the positioning installation shaft 41 is set through the positioning tooth plate 42, the positioning tooth plate 42 matches the lifting tooth plate 222, and the positioning spring 43 is set between the pair of positioning tooth plates 42.

[0057] S1. Pre-process the wire and cut it using an automatic wire cutting machine.
