Description

Technical Field

[0001] The invention relates to the technical field of automobile wiring harnesses, in particular to an automobile wiring harness plastic shell fixing frame. Background Art

[0002] In modern cars, there are a lot of wiring harnesses, and the electronic control system is closely related to the wiring harness. Someone once made a vivid metaphor: if the functions of microcomputers, sensors and actuators are compared to the human body, it can be said that the microcomputer is equivalent to the human brain, the sensor is equivalent to the sensory organ, the actuator is equivalent to the motor organ, and the wiring harness is the nerve and blood vessel. The automotive wiring harness is the network body of the automotive circuit, connecting the electrical and electronic components of the car and making them function. Without the wiring harness, there would be no automotive circuit. At present, whether it is a high-end luxury car or an economical ordinary car, the wiring harness is basically the same, consisting of wires, connectors and wrapping tapes. It must ensure the transmission of electrical signals and also ensure The wiring harness is the main network of the automobile circuit. Without the wiring harness, there is no automobile circuit. The wiring harness refers to the contact terminal (connector) punched from copper material, which is crimped with the wire and cable, and then the insulator or metal shell is pressed on the outside to form a component of the connecting circuit. The wiring harness industry chain includes wires and cables, connectors, processing equipment, wiring harness manufacturing and downstream application industries. The wiring harness is widely used and can be used in automobiles, household appliances, computers and communications equipment, various electronic instruments and meters, etc. The body wiring harness connects the entire body and is generally H-shaped.

[0003] The existing wiring harness plastic shell is basically exposed and placed in the vehicle body, and is only used for wiring harness connection. The placement method is disorderly, which can easily cause the connected wiring harness plastic shells to separate from each other, causing the vehicle power supply to separate from the operator, which in turn causes operation failure during driving, causing the vehicle to lose control and cause a traffic accident, which is extremely harmful. At the same time, the existing plastic shell is extremely chaotic in placement, which can cause multiple wiring harnesses to be entangled with each other. The entanglement of the wiring harnesses will shorten the actual usable length of the wiring harness, making it impossible for the wiring harness to be connected to the structure that it could originally be connected to. At the same time, the entanglement of the wiring harness will cause the heat generated by the wiring harness to gather together, increasing the temperature of the vehicle body, resulting in higher energy loss of the vehicle body. At the same time, multiple wire harnesses are connected through the plastic shell, and can only be disassembled one by one when disassembling and repairing the wiring harness, which is time-consuming and labor-intensive. Incomplete disassembly may also cause workers to be electrocuted, causing hazards that cannot be ignored. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an automobile wiring harness plastic shell fixing frame, which has the advantages of being able to fix wiring harnesses of different sizes and prevent vibration from causing the wiring harness to loosen, and quickly reducing the heat generated by the wiring harness during operation, thereby solving the problem that the existing wiring harness plastic shell is basically exposed and placed in the vehicle body, and is only used for wiring harness connection. The placement method is disorderly, which is extremely easy to cause the connected wiring harness plastic shells to separate from each other, so that the vehicle power supply is separated from the operator, and then cause operation failure during driving, causing the vehicle to lose control and cause a traffic accident, which is extremely harmful. At the same time, the existing plastic shell is extremely chaotic in placement, which will cause multiple wiring harnesses to be entangled with each other. The entanglement of the wiring harnesses will shorten the actual usable length of the wiring harness, making it impossible for the wiring harness to be connected to the structure that it could originally be connected to. At the same time, the entanglement of the wiring harness will cause the heat generated by the wiring harness to gather together, increase the temperature of the vehicle body, and cause high energy loss of the vehicle body. At the same time, multiple strands of wiring harnesses are connected through the plastic shell, and can only be disassembled one by one when disassembling and repairing the wiring harness, which is time-consuming and labor-intensive. In the case of incomplete disassembly, it may also cause workers to be electrocuted, causing harmful problems that cannot be ignored.

The operation of the second spring 13 enables the limiting block 14 to elastically contract, and the surface of the limiting block 14 is slidingly connected to the surface of the inner wall of the fixing groove 10. By pressing the limiting block 14, the second spring 13 is driven to contract, thereby adjusting the height of the support frame 11 up and down. Loosening the limiting block 14 allows the limiting block 14 to enter the fixing groove 10 under the rebound of the second spring 13 to limit the support frame 11.

A second wiring harness shell 17 is fixedly installed on one end of the third spring 16. Through the operation of the third spring 16, the second wiring harness shell 17 can be buffered and adapted to the shaking and pressure caused by vibration.

[0023] Among them; the side of the second wiring harness shell 17 is slidably connected to one side of the inner wall of the first slot 8, and the second wiring harness shell 17 is lowered to enter the first slot 8 so that the first wiring harness shell 7 and the second wiring harness shell 17 contract with each other to tighten and fix the wiring harness, and a square groove 18 is opened on the side of the support platform 4, and the position of the movable frame 15 can be fixed by the setting of the square groove 18.

[0025] Among them, a condensing device 21 is fixedly installed on one side of the inner wall of the empty slot 19, and the operation of the condensing device 21 can be used to cool down and quickly reduce the temperature inside. A curved heat dissipation pipe 22 is fixedly installed on one side of the inner wall of the condensing device 21, and the setting of the curved heat dissipation pipe 22 can quickly diffusely reduce the temperature inside the empty slot 19.

[0026] Among them; one end of the curved heat dissipation pipe 22 is fixedly connected to one side of the inner wall of the slot 19, and exhaust holes 23 are opened on the side of the base plate 1 and the side of the support platform 4. Through the setting of the exhaust holes 23, air can be transmitted through the inside of the slot 19 to the surface of the support platform 4, thereby cooling the components on the surface of the support platform 4.

[0027] Among them; a third circular groove 24 is opened on the side of the base plate 1, and a protective shell 25 is fixedly installed on the side of the base plate 1. The setting of the protective shell 25 can protect the first motor 27 and the cooling fan 28 to prevent the impact force generated by external vibration from causing damage to the two, which requires a lot of time for maintenance later.

[0028] One end of the protective shell 25 is fixedly mounted with a dust plate 26, and one end of the dust plate 26 is fixedly mounted with a first motor 27.

[0029] Among them; a cooling fan 28 is fixedly installed at one end of the first motor 27, and the surface of the cooling fan 28 is movably connected to the surface of the inner wall of the third circular groove 24. The cooling fan 28 is driven to rotate by the operation of the first motor 27. The dustproof plate 26 blocks the dust in the air when the cooling fan 28 rotates. The curved heat pipe 22 is cooled by the operation of the condensing device 21. The cold air generated when the curved heat pipe 22 is cooled is transmitted by the operation of the cooling fan 28. During the transmission, the cold air is discharged into the direction of the first wiring harness shell 7 and the second wiring harness shell 17 through the exhaust hole 23, thereby quickly reducing the heat generated when the wiring harness is in operation.

[0030] Among them; by pressing the limit block 14, the second spring 13 is driven to contract, so as to adjust the height of the support frame 11 up and down. The limit block 14 is loosened, and the limit block 14 enters the fixing groove 10 under the rebound of the second spring 13 to limit the support frame 11. The height adjustment of the support frame 11 drives the movable frame 15 to be adjusted, and the operation of the third spring 16 enables the second wiring harness shell 17 to be buffered and adapted, and the operation of the first spring 6 enables the first wiring harness shell 7 to be buffered and adapted, and the second wiring harness shell 17 is descended to enter the first clamping groove 8 so that the first wiring harness shell 7 and the second wiring harness shell 17 contract with each other to tighten and fix the wiring harness, and the movable frame 15 is descended to enter the square groove 18 for secondary fixation to prevent shaking when the first wiring harness shell 7 and the second wiring harness shell 17 are clamped.

[0031] Among them; the operation of the first motor 27 drives the cooling fan 28 to rotate, and the dustproof plate 26 blocks the dust in the air when the cooling fan 28 rotates to prevent the dust in the air from entering. The long-term intrusion of dust causes excessive dust accumulation inside the first motor 27 and causes damage to the first motor 27. The curved heat pipe 22 is cooled by the operation of the condensing device 21. The cold air generated when the curved heat pipe 22 is cooled is transmitted through the operation of the cooling fan 28. During the transmission, the cold air is discharged into the direction of the first wiring harness shell 7 and the second wiring harness shell 17 through the exhaust hole 23, thereby quickly reducing the heat generated when the wiring harness is in operation.

[0032] The working principle is that by pressing the limit block 14, the second spring 13 is driven to contract, so as to adjust the height of the support frame 11 up and down. After the adjustment is completed, the limit block 14 is released. Under the rebound of the second spring 13, the limit block 14 enters the fixing groove 10 to achieve the limitation of the support frame 11. The height of the support frame 11 is adjusted to drive the movable frame 15 to adjust its height. Through the operation of the third spring 16, the second wiring harness shell 17 can be buffered and adapted to prevent the device from being damaged by the fluctuation caused by the vibration, and the first wire harness shell 7 is buffered and adapted to prevent the device from being damaged by the fluctuation caused by the vibration, and the first wire harness shell 7 is buffered and adapted to prevent the device from being damaged by the fluctuation caused by the vibration, and the movable frame 15 is lowered to make the second wire harness shell 17 descend and enter the first fixing groove 8, so that the first wire harness shell 7 and the second wire harness shell 17 contract with each other to tighten the wiring harness, thereby fixing the wiring harness to prevent friction. The outer skin is damaged, and the movable frame 15 is lowered into the square groove 18 for secondary fixation to prevent the first wiring harness shell 7 and the second wiring harness shell 17 from shaking when clamped. The operation of the first motor 27 drives the cooling fan 28 to rotate, and the dustproof plate 26 blocks the dust in the air when the cooling fan 28 rotates to prevent the entry of dust in the air. The long-term intrusion of dust causes excessive dust accumulation inside the first motor 27, resulting in damage to the first motor 27. The operation of the condensing device 21 reduces its own temperature to cool the curved heat pipe 22. When the curved heat pipe 22 is cooled by the condensing device 21, the cold air generated is transmitted through the operation of the cooling fan 28. During transmission, the cold air is discharged into the direction of the first wiring harness shell 7 and the second wiring harness shell 17 through the exhaust hole 23, thereby quickly reducing the heat generated during the operation of the wiring harness, preventing the wiring harness from overheating and causing the wiring harness to soften, thereby causing serious problems such as fire.
