Description

Technical Field

[0001] The utility model relates to the technical field of automobile wiring harnesses, in particular to a rubber protective cover for automobile wiring harnesses. Background Art

[0002] The automotive wiring harness is the network body of the automotive circuit. Without the wiring harness, there would be no automotive circuit. The wiring harness refers to the contact terminals made of copper material, which are crimped with wires and cables, and then plastic-pressed with insulators or metal shells on the outside to form components that connect the circuits. The wiring harness inside the car door needs to be bent frequently, and the external rubber protective cover is prone to wear and damage during long-term bending, so the protective cover often needs to be replaced.

[0003] Patent document CN216162339U discloses an oil-proof rubber protective cover for automotive wiring harnesses, "relating to the technical field of automotive wiring harnesses, including a protective cover, both ends of the protective cover are fixedly connected to an aluminum foil tube, and a receiving hole is opened in the middle of the aluminum foil tube, and a locking band is fixedly connected to the inner wall of the end of the receiving hole. The utility model provides a locking band, which can cooperate with the locking band and the locking teeth at the bottom of the locking frame to tightly wrap the aluminum foil tube around the side of the wiring harness. When disassembling, the pressing plate can be pried open with the fingers using the prying groove to loosen the locking band, thereby achieving the purpose of easy installation and easy disassembly. By providing a protective cover, the interface of the wiring harness can be prevented from being contaminated after it is connected, and the wax coating can be both waterproof and oil-proof. At the same time, the fireproof mud ring is expanded to fill the gap between the wiring harness and the aluminum foil tube to prevent external water or oil from entering. After the fireproof mud ring is dried, it can achieve the effects of sealing and waterproofing."

[0004] When the above device is in use, by setting a locking belt, the locking belt can cooperate with the locking teeth at the bottom of the locking frame to enable the aluminum foil tube to be tightly wrapped around the side of the wiring harness. When disassembling, you only need to use the prying groove to pry open the pressing plate with your fingers to loosen the locking belt. However, when the protective cover is used for a long time, wear and tear will generally occur in a certain section of the protective cover. When replacing it, the entire protective cover needs to be removed and replaced, which is likely to result in a waste of resources. Therefore, it is necessary for staff to make improvements.

[0026] When using this device to protect and install the automobile wiring harness, the material of the protective bottom cover 1 and the protective top cover 3 is made of rubber. The protective bottom cover 1 is placed at the bottom of the automobile wiring harness, and the inner wall of the protective bottom cover 1 is fitted on the surface of the automobile wiring harness. Then, the rotating rod 2 is rotated to drive the protective top cover 3 to rotate, and the protective top cover 3 is fitted and fixed with the protective bottom cover 1. Then, the second set of protective top cover 3 and the protective bottom cover 1 are put on the surface of the automobile wiring harness, and then the plug block 4 is inserted into the top of the protective top cover 3. The square groove is then inflated, and the knob 7 is then turned so that the knob 7 drives the screw 6 at the bottom to rotate. The screw 6 drives the pushing block 8 at the bottom to move downward and contact the surface inside the fixed block 9. The plug-in block 4 moves downward, causing the pushing block 8 to push the fixed block 9 to the left and right. At this time, the fixed block 9 extends out of the plug-in block 4 and inserts into the inner wall of the protective top sleeve 3, thereby completing the splicing of the two sets of protective sleeves. When a set of protective sleeves is damaged, the connection box 5 can be removed and the protective top sleeve 3 can be rotated to remove the set of protective sleeves.

[0027] See also Figures 1 to 5 A rubber protective cover for an automotive wiring harness: The left side of the protective bottom cover 1 is fixedly connected to a first connecting rod 10, and the left side of the protective top cover 3 is fixedly connected to a second connecting rod 11.
