Description

Technical Field

[0001] This utility model relates to the technical field of automotive wiring harnesses, specifically to a through-hole rubber sheath for automotive engine compartment wiring harnesses. Background Technology

[0002] As people's living standards continue to improve, their demands for automotive safety and comfort are gradually increasing. Consequently, the number of electronic and electrical components in automobiles is also increasing, leading to a greater number and thickness of wiring harnesses from the driver's cab to the engine compartment. During installation, rubber sleeves are often used to protect the wiring harness and facilitate sealing of the wiring harness holes. However, the rubber sleeve bends with the wiring harness, making the contact between the rubber sleeve and the car's holes less tight. This creates gaps in the car's holes, allowing dust and water to enter. For example, the patent publication number CN218449297U, entitled "A Wear-Resistant Rubber Sealing Sleeve for Automotive Wiring Harnesses," solves the above technical problem. However, during use, the sealing sleeve bends with the wiring harness, resulting in more wear near the mounting holes and affecting the overall service life of the rubber sleeve. Utility Model Content

[0003] The purpose of this utility model is to provide a through-hole rubber sleeve for automotive engine compartment wiring harnesses, which can better protect the wiring harness and increase the performance of its through-holes.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A through-hole rubber sleeve for an automotive engine compartment wiring harness includes a rubber sleeve body fitted over the wiring harness. A through-hole protection device is provided on the outer side of the rubber sleeve body.

[0018] like Figures 1-3As shown, a through-hole rubber sleeve for an automotive engine compartment wiring harness includes a rubber sleeve body 1 fitted over the wiring harness, providing overall protection for the wiring harness. A through-hole protection device is provided on the outer side of the rubber sleeve body 1. The through-hole protection device includes two baffle devices 2 that can move up and down along the rubber sleeve body 1 and can extend and retract in the horizontal direction, providing sealing protection at the through-hole. A clamping device 3 is provided between the two baffle devices 2. The clamping device 3 includes at least two clamping components, including an arc-shaped first clamping plate 7 and a second clamping plate 14. The first clamping plate 7 and the second clamping plate 14... Several spaced springs 10 are fixed between the two clamping plates 14. A limit post 13 is fixed on the inner side of the second clamping plate 14. The rubber sheath body 1 is provided with a limit groove corresponding to the limit post 13. The limit post 13 is inserted into the corresponding limit groove to limit the movement of the wire harness and the rubber sheath body 1. It also serves as a pre-installation function. When the rubber sheath body 1 bends with the wire harness, the second clamping plate 14 of the corresponding clamping component can move appropriately with it. The corresponding part of the baffle device 2 can also extend and retract appropriately with it to adapt to the bending and other changes of the wire harness.

[0019] The baffle device 2 includes an inner ring 4 and an outer ring 6. A retractable pleated part 5 is fixed between the inner ring 4 and the outer ring 6 to facilitate adaptation to changes such as bending of the wire harness. The inner side of the inner ring 4 fits against the outer side of the rubber sheath body 1 to facilitate sealing.

[0020] A horizontal column 8 is fixed to the middle of the inner side of the first tightening plate 7. A vertical hole is provided on the second tightening plate 14, and a vertical column 11 is inserted into the vertical hole. A corresponding insertion groove is provided on the outer side of the second tightening plate 14, and the insertion groove communicates with the vertical hole. A vertical positioning hole 9 is provided on the horizontal column 8, which can cooperate with the vertical column 11. In the initial state, the horizontal column 8 is inserted into the insertion groove, and the inner end of the horizontal column 8 extends into the vertical hole. The vertical column 11 is set in the positioning hole 9, so that the first tightening plate 7 and the second tightening plate 14 are in a relatively close state. The spring 10 is in a compressed state. After the tightening device 3 is installed on the rubber sleeve body 1, it is easy to install it in the through hole. After it is installed in the through hole, the vertical column 11 is moved upward, so that the vertical column 11 is moved out of the positioning hole 9. The spring 10 rebounds, and the first tightening plate 7 is pressed against the inner wall of the through hole.

[0021] The two ends of the vertical column 11 extend to the outside of the second top plate 14 to facilitate the vertical movement of the vertical column 11. The second top plate 14 is provided with grooves that cooperate with the ends of the vertical column 11. When the baffle device 2 is installed in place, the ends of the vertical column 11 are set in the corresponding grooves.

[0022] A rubber pad 15 is fixed to the inner side of the second clamping plate 14. The inner side of the rubber pad 15 is in contact with the outer side of the rubber sheath body 1. The rubber pad 15 is provided with a through hole corresponding to the limiting post 13. The limiting post 13 extends to the outside of the through hole.

[0023] The outer ring 6 has several arc-shaped holes 16, which facilitates the installation of bolts in the arc-shaped holes 16, so that the outer ring 6 can be detachably fixed to the vehicle body by bolts.

[0024] During installation, the rubber sheath body 1 is fitted over the outside of the wiring harness for protection. The tightening device 3 is in its initial state. The limiting post 13 on the second tightening plate 14 is placed in the corresponding limiting groove for limiting. After the tightening device 3 is installed on the rubber sheath body 1, it is installed in the through hole. After it is installed in the through hole, the vertical post 11 is moved upward, so that the vertical post 11 moves out of the positioning hole 9. The spring 10 returns, and the first tightening plate 7 is pressed against the inner wall of the through hole. Then the vertical post 11 is placed in the initial position, and the two baffle devices 2 are moved. Make them fit together with the two ends of the through hole respectively, and set the bolt in the corresponding arc hole 16. The outer ring 6 is detachably fixed to the vehicle body by the bolt. During use, when the rubber sheath body 1 bends with the wire harness, the second clamping plate 14 of the corresponding clamping component can move appropriately with it. That is, the spring 10 of one clamping component is compressed and the spring 10 of the other clamping component is stretched, so that the second clamping plate 14 can move appropriately with it. The corresponding part of the baffle device 2 can also extend and retract appropriately with it to adapt to the bending and other changes of the wire harness.

[0025] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
