Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to an automobile connecting wire harness with a rubber protection function. Background Art

[0002] The wiring harness for automobiles refers to a group of wires, cables and connectors that are combined together for use in the electrical system of the car. The wiring harness plays a key role in the car. They transmit power and data signals and connect various parts of the car, such as the engine, transmission system, lights, dashboard and entertainment system. However, rubber can provide effective protection for the wiring harness, making it less susceptible to damage and erosion from the external environment.

[0003] Traditional automotive wiring harnesses with rubber protection are usually wrapped with a layer of rubber material to provide additional protection and insulation.

[0004] Traditional automotive wiring harnesses with rubber protection function have the following problems: they cannot be adjusted according to the length of the wires to be protected, the length of the rubber sleeve cannot be flexibly changed, and they do not have a fixing function. They are prone to displacement or loosening during vehicle operation or vibration, causing the wires or cables in the wiring harness to be exposed to the external environment, increasing their risk of wear or damage by external objects.

[0011] Furthermore, the lengths of the splints are all equal, thereby improving stability during fixation.

[0012] Furthermore, the clamping mechanism also includes a turntable, a rotating shaft, a guide slot and a rotating groove. The rotating slots are all opened on the inner wall of the fixed shell on one side close to the center of the rubber bellows. The inner wall of the rotating slot is rotatably connected to the turntable. The inside of the turntable is provided with evenly distributed guide slots. The rotating shaft is rotatably connected to the side of the clamp plate close to the center of the rubber bellows. The inner ends of the rotating shafts are all located inside the adjacent guide slots to facilitate conversion into linear motion.
