Description

Technical Field

[0001] The invention relates to the technical field of automobile wiring harnesses, in particular to an automobile wiring harness fixing clip. 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] According to traditional automobile wiring harness fixing clamps, most of the positions are fixed and cannot be adjusted according to the length of the wiring harness, so that the wiring harness cannot be well supported when fixed, resulting in the wiring harness being too loose. After the vibration generated during the driving of the car is transmitted to the device, the wiring harness is too loose and causes the wiring harness to fall off, causing control failure, thereby causing accidents and dangers. In addition, most wiring harness fixing clamps cannot clamp and fix lines of different sizes, so it is necessary to replace matching devices for clamping and fixing, which is troublesome. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an automobile wiring harness fixing clamp, which has the advantage of controlling the supporting points when fixing the wiring harness so that the wiring harness will not be in a loose state to prevent it from falling off due to vibration, and fixing wiring harnesses of different sizes to avoid the trouble of replacing matching wiring clamps. It solves the problem that most positions of traditional automobile wiring harness fixing clamps are fixed and cannot be adjusted according to the length of the wiring harness, so that the wiring harness cannot be well supported when fixed, resulting in the wiring harness being too loose, and after the vibration generated during the driving of the car is transmitted to the device, the wiring harness falls off due to the excessive looseness, causing control failure and thus accidents and dangers, and most wiring harness fixing clamps cannot clamp and fix lines of different sizes, so it is necessary to replace matching devices for clamping and fixing, which is troublesome.

After the adjustment is completed, the moving rod is driven to reset by the second spring. When the support frame moves, the limit block moves in the slide groove so that the support frame will not deviate during movement. When the support frame is vibrated, the buffer plate is driven to operate by the first spring to reduce the vibration of the support frame. The support point of the wiring harness when fixed can be controlled through the movement of the support frame to prevent the wiring harness from loosening, and the first support block is fixedly installed on the side of the support frame.

[0007] Preferably, a first support rod is fixedly installed on the side of the first support block, and a first rotating shell is movably installed on the surface of the first support rod. The setting of the first support block ensures that the first support rod will not shake during operation, and the first rotating shell is movably installed on the surface of the first support rod.

[0008] Preferably, a first clamping block is fixedly mounted on the surface of the first rotating shell, and a second rotating shell is movably mounted on the surface of the first support rod. The setting of the first rotating shell prevents the first clamping block from shaking during operation, and the second rotating shell is movably mounted on the surface of the first support rod.

When the angle is adjusted, the operation of the first rotating shaft drives the fixing block to adjust the angle, thereby driving the third spring to operate, and the operation of the third spring allows the first clamping block and the second clamping block to provide buffer support when the angle is adjusted. The first clamping block and the second clamping block are adjusted to adapt to wiring harnesses of different sizes. When the wiring harness is placed between the first clamping block and the second clamping block, the operation of the third spring brings the two closer to each other, and the U-shaped clamping block is driven to rotate by rotating the threaded rod so that the U-shaped clamping block descends and contacts the sides of the first clamping block and the second clamping block, thereby tightening the two to achieve clamping and fixing of the wiring harness.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The automobile wiring harness fixing clamp drives the moving rod to move in the circular groove by pushing the turning handle, thereby driving the first gear to approach the rack block, and drives the moving rod to rotate by turning the turning handle, thereby driving the first gear to rotate, and the rack block is moved by the rotation of the first gear, and the support frame is moved by the movement of the rack block. After the adjustment is completed, the moving rod is reset by the second spring, and when the support frame moves, the limit block moves in the slide groove so that the support frame will not deviate when moving. When the support frame is vibrated, the buffer plate is driven to operate by the first spring to reduce the vibration of the support frame. The support point when the wiring harness is fixed can be controlled by the movement of the support frame to prevent the problem of loose wiring harness.

[0016] 2. The automobile wiring harness fixing clamp adjusts the angle of the first clamping block and the second clamping block by rotating the first rotating shell and the second rotating shell on the surface of the first support rod. When adjusting the angle, the operation of the first rotating shaft drives the fixing block to adjust the angle, thereby driving the operation of the third spring. The operation of the third spring provides buffer support when the angle of the first clamping block and the second clamping block is adjusted. The first clamping block and the second clamping block are adjusted to adapt to wiring harnesses of different sizes. When the wiring harness is placed between the first clamping block and the second clamping block, the third spring operates to bring the two closer to each other. The rotating handle drives the threaded rod to rotate so that the U-shaped clamping block descends to contact the sides of the first clamping block and the second clamping block, thereby tightening the two to achieve clamping and fixing of the wiring harness. The above structure effectively solves the problem of adapting to and clamping wiring harnesses of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS
