A stabilizing sheath for high-speed transmission automotive wiring harnesses

Abstract

This utility model discloses a stable sheath for high-speed transmission automotive wiring harnesses, including a sleeve, a corrugated tube, and an installation structure. After the sleeve is fitted into the installation space, a locking sleeve presses against the surface of the installation location, while a sealing ring is located between the locking sleeve and the plate surface. Next, a threaded sleeve is connected to the threaded sleeve, causing the pressure sleeve to move on the sleeve surface and then press against the plate surface. With continuous rotation, the pressure sleeve presses tightly against the plate surface, ensuring the sealing ring is tightly filled between the locking sleeve and the plate surface. The locking sleeve and pressure sleeve press against the plate surface, firmly fixing the sleeve and improving installation stability. Rotating the screw and pushing down the pressure block causes the engagement block to press tightly against the threaded surface of the threaded sleeve, thus locking the threaded sleeve from rotating and preventing loosening due to vibration.

[0013] Preferably, the spring is always in a state of stress deformation.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] After the sleeve is placed in the installation space, the retaining sleeve presses against the surface of the installation location, while the sealing ring is located between the retaining sleeve and the plate surface. Next, the threaded sleeve is connected to the threaded sleeve, causing the pressure sleeve to move on the surface of the sleeve and then press against the plate surface. With continuous rotation, the pressure sleeve will press tightly against the plate surface, so that the sealing ring is tightly filled between the retaining sleeve and the plate surface. The retaining sleeve and the pressure sleeve press against the plate surface, making the sleeve firmly fixed and improving the stability of the installation. Rotate the screw and then push the pressure block down, so that the engagement block presses tightly against the threaded surface of the threaded sleeve, thereby locking the rotation of the threaded sleeve, so that vibration will not cause the threaded sleeve to rotate and loosen.

Detailed Implementation

[0021] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0022] Please see Figure 1 and Figure 2 This utility model provides a stable sheath for high-speed transmission automotive wiring harnesses, including a sleeve 1, a corrugated pipe 2 provided on the sleeve 1, and an installation structure 3 provided on the sleeve 1.

[0023] Specifically, the high-speed transmission vehicle wiring harness is fed into the sleeve 1. The corrugated tube 2 on the sleeve 1 can be bent when the sleeve 1 needs to be bent in order to adjust its position. The sleeve 1 can protect the internal wiring harness and thus protect the wiring harness.

[0024] Please see Figure 2 , Figure 3 and Figure 4 This utility model provides a stable sheath for high-speed transmission automotive wiring harnesses. The mounting structure 3 includes a locking sleeve 31, which is integrally formed on the sleeve 1. A sealing ring 32 is provided on the surface of the locking sleeve 31 and is fitted onto the sleeve 1.

[0025] The end of the sleeve 1 is integrally formed with a threaded sleeve 33, and the surface of the threaded sleeve 33 is threadedly connected with a threaded sleeve 34. The outer surface of the threaded sleeve 34 is provided with at least two planes, and the two planes are symmetrical, so as to use tools such as wrenches to rotate the threaded sleeve 34 for tight compression and reinforcement. The surface of the threaded sleeve 34 is integrally formed with a pressure sleeve 35, and the surface of the threaded sleeve 34 is provided with a fastening structure 36.

[0026] In this utility model, the fastening structure 36 includes a fixed seat 361. The fixed seat 361 is integrally formed on the surface of the threaded sleeve 34. A threaded seat 362 is fixed on the fixed seat 361. A screw 363 is threadedly connected to the threaded seat 362. A pressure block 364 is rotatably connected to the end of the screw 363. A biting block 365 is provided on the surface of the pressure block 364. The biting block 365 is elastic and has threads on its surface that connect with the threaded sleeve 33, so that the threaded sleeve 34 will not be blocked by the biting block 365 when it rotates.

[0027] The pressure block 364 is quadrilateral and rests against the inside of the fixed seat 361 to limit its position. A spring 366 is fixed to the surface of the pressure block 364. One end of the spring 366 is fixed to the inside of the fixed seat 361. The spring 366 is always in a state of stress deformation, which can make the thread of the screw 363 always fit with the internal thread of the thread seat 362, improving the firmness and making it less prone to rotation.

[0028] Specifically, after sleeve 1 is fitted into the installation space, locking sleeve 31 is pressed against the surface of the installation location, while sealing ring 32 is located between locking sleeve 31 and plate surface. Then, threaded sleeve 34 is connected to threaded sleeve 33, causing pressure sleeve 35 to move on the surface of sleeve 1 and then press against plate surface. With continuous rotation, pressure sleeve 35 will press tightly against plate surface, causing sealing ring 32 to be tightly filled between locking sleeve 31 and plate surface. Furthermore, the locking sleeve 31 and pressure sleeve 35 press against plate surface, making sleeve 1 firmly fixed and improving installation stability. Rotating screw 363, since screw 363 is threadedly connected to threaded seat 362, when screw 363 rotates, screw 363 will push downward and then push down pressure block 364, causing engagement block 365 to press tightly against the threaded surface of threaded sleeve 33, thereby locking threaded sleeve 34 from rotating, so that vibration will not cause threaded sleeve 34 to rotate and loosen.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
