Description

Technical Field

[0001] This utility model belongs to the field of sheath technology, and specifically relates to an automotive wiring harness sheath. Background Technology

[0002] Automotive wiring harnesses are the main network of automotive circuits; without them, there would be no automotive circuitry. To make wiring harness connections more convenient and layouts neater, automotive wiring harness sleeves were developed. The wiring harness is run through the sleeve, which protects it. These sleeves are typically used to connect the left and right doors, the trunk lid, and the vehicle body, preventing wear and tear on the wiring during opening and closing. They also prevent mud and water from entering the doors and body, thus preventing electrical short circuits and potential electrical malfunctions and fires.

[0003] Currently, there are gaps at the connection points between automotive wiring harness sheaths and the vehicle body. In particular, wiring harness sheaths are generally made of corrugated flexible tubing with strong deformation capacity. When the corrugated tubing deforms, the gap at the connection point with the vehicle body widens. This allows water or dust to easily seep into the wiring harness sheath through the gaps, thus affecting the normal operation of the automotive wiring harness. In addition, automotive wiring harness sheaths generally extend into the wiring hole slots in the vehicle body. While this makes it convenient to pull out and expose the wiring harness for maintenance, the connection between the wiring harness sheath and the vehicle body is not very secure. Furthermore, if the wiring harness sheath falls off, it will exacerbate the large gap between it and the vehicle body, creating a risk of water and dust ingress. Summary of the Invention

The end face of the connector 1 is provided with an elastic buckle mechanism, which includes a pressing handle 5, a return spring 6, and an anti-detachment buckle 9. The pressing handle 5 is slidably connected to the inside of the connector 1. The return spring 6 is fixed between the pressing handle 5 and the inner wall of the connector 1. The anti-detachment buckle 9 is fixed to one end of the pressing handle 5. The surface of the connector 1 is provided with an inflation sealing mechanism, which includes a sealing airbag 10 and a valve 11. The sealing airbag 10 is sleeved on the end of the connector 1 away from the corrugated hose 2. The valve 11 is fixed to one end face of the sealing airbag 10.

[0022] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the connector 1 has a hollow interlayer 4 inside, and telescopic guide posts 7 are horizontally fixed between the walls where the hollow interlayer 4 is located.

[0023] Further as Figure 3 As shown, it is worth noting that the reset spring 6 is sleeved on the outside of the telescopic guide post 7, and a telescopic guide hole 8 is provided through one side surface of the pressing handle 5. The telescopic guide hole 8 slides and matches the telescopic guide post 7.

[0024] The solution has the following working process: Before use, the automotive wiring harness is inserted into one connector 1, passes through the corrugated hose 2, and exits from another connector 1. When the connector 1 is connected to the automotive body, it is pressed against the pressing handle 5. This causes the two pressing handles 5 to be compressed against the return spring 6, which in turn causes the two anti-detachment clips 9 to retract towards each other. Then, the connector 1 passes through the wiring hole slot of the automotive body. After releasing the pressing handle 5, the anti-detachment clip 9 at the end of the pressing handle 5 is reset under the rebound force of the return spring 6 and is located on the other side of the wiring hole slot of the automotive body. The anti-detachment clip 9, which is raised on the connector 1, can achieve the anti-detachment function at the wiring hole slot of the automotive body.

[0025] According to the above working process, first, control the connector 1 to pass through the wire hole slot of the car. Then, press the anti-disengagement buckle 9 at the end of the handle 5 and reset it under the action of the return spring 6 and place it on the other side of the wire hole slot of the car. The anti-disengagement buckle 9, which is in a raised state on the connector 1, can achieve the anti-disengagement function at the wire hole slot of the car.

[0026] Further as Figure 3 , Figure 4 and Figure 5 As shown, it is worth noting that one end of the reset spring 6 is fixed to the wall where the hollow interlayer 4 is located, and the other end of the reset spring 6 is fixed to the end face of the pressing handle 5.

[0027] Further as Figure 4 As shown, it is worth noting that a receiving groove 13 is provided on one end face of the connector 1, and the anti-detachment buckle 9 is provided in the receiving groove 13 of the connector 1.

One end of the valve 11 extends into the relief opening 12 of the connector 1. After the connector 1 is inserted into the car's wiring hole groove, the uninflated sealing airbag 10 is also in the car's wiring hole groove. At this time, air is inflated into the sealing airbag 10 from the valve 11. After the sealing airbag 10 is inflated, it bulges and fills the connection seam between the car's wiring hole groove and the connector 1. This can enhance the sealing between the connector 1 and the car's wiring hole groove to ensure good waterproof and dustproof performance.

[0030] Further as Figure 1 As shown, it is worth noting that the two pressing handles 5 are symmetrically arranged on the upper side surface of the connector 1, and both the connector 1 and the corrugated hose 2 have wire passages 3 inside.
