It includes a protective tube and a conductor located within the protective tube. The protective tube is made of light steel and includes sequentially connected joints. One end of each joint has a female connector, and the other end has a male connector. The female connector is accommodated within the male connector. For two adjacent joints on the protective tube, joint one and joint two, they are rotatably connected via adjacent female and male connectors. The conductor passes through the interior of joint one and joint two, and the protective tube provides protection by wrapping the conductor. Multiple sequentially connected joints enable the protective tube to bend. This automotive wiring harness achieves the effect of supporting and protecting the wires. However, the aforementioned automotive wiring harnesses are secured by their own stress during connection. This stress makes them prone to detachment under accidental contact with external forces, leading to interruption of connection control data and affecting the normal operation of vehicle control.

[0027] like Figures 1 to 4 As shown, the present invention provides an anti-detachment structure for automotive wiring harnesses, including a wire end assembly 1;

[0028] The insert frame component 2 is installed behind the head component 1;

[0029] The top and bottom of the wire end assembly 1 are both fixedly connected to an anti-detachment mechanism 3. The anti-detachment mechanism 3 includes a fixed plate 4. The outer side of the fixed plate 4 is fixedly connected to a longitudinal plate 5. An extension post 6 is provided through the inner side of the longitudinal plate 5. The inner side of the extension post 6 extends through to the inner side of the longitudinal plate 5 and is fixedly connected to a movable plate 7. A spring 8 is sleeved on the surface of the extension post 6. The inner side of the spring 8 is fixedly connected to the movable plate 7. The outer side of the spring 8 is fixedly connected to the longitudinal plate 5. The inner side of the movable plate 7 is slidably connected to the fixed plate 4. A rear plate 9 is fixedly connected to the inner side of the movable plate 7. A locking block 10 is fixedly connected to the rear side of the inner side of the rear plate 9. The top and bottom of the insertion frame assembly 2 are both fixedly connected to a strip 11. The inner side of the locking block 10 is locked inside the strip 11. The front and rear sides of the outer side of the longitudinal plate 5 are slidably connected to a shaped rod 12. The side of the shaped rod 12 away from the longitudinal plate 5 extends through to the interior of the extension post 6.

[0030] refer to Figure 1 , Figure 2 and Figure 3 A separation mechanism 13 is movably connected to the outer side of the fixed plate 4 via a bearing. The separation mechanism 13 includes a rotating rod 14. An elliptical disk 15 is fixedly connected to the surface of the rotating rod 14. The outer side of the elliptical disk 15 contacts the moving plate 7. A disc 16 is fixedly connected to the outer side of the rotating rod 14. A pin 17 is fixedly connected to the outer side of the disc 16.

[0031] As a technical optimization of this utility model, the separation mechanism 13 enables the card block 10 to be separated quickly, increasing the user's convenience in separation.

[0032] refer to Figure 3 The fixed plate 4 has movable grooves 18 on both sides of its outer side, and the inner side of the movable plate 7 is slidably connected to the inside of the movable grooves 18.

[0033] As a technical optimization of this utility model, the movable groove 18 enables the movable plate 7 to slide more smoothly inside the fixed plate 4, reduces the friction between the movable plate 7 and the fixed plate 4, extends the service life of the movable plate 7, and at the same time limits the movement of the movable plate 7.

[0034] refer to Figure 3 Both the front and back sides of the extension column 6 are provided with abutment grooves 19, and the side of the irregular rod 12 away from the longitudinal plate 5 is engaged inside the abutment groove 19.

[0035] As a technical optimization of this utility model, by setting the clamping groove 19, the irregular rod 12 can be more firmly locked into the inside of the extension column 6, avoiding the phenomenon of falling off.

[0036] refer to Figure 3The front and rear sides of the outer side of the longitudinal plate 5 are provided with grooves 20, and the inner side of the irregular rod 12 is slidably connected to the inside of the grooves 20.

[0037] As a technical optimization of this utility model, the groove 20 allows the irregular rod 12 to slide more smoothly inside the longitudinal plate 5, reducing the friction between the two.

[0038] refer to Figure 2 A pull plate 21 is fixedly connected to the outside of the extension column 6, and the pull plate 21 is used in conjunction with the extension column 6.

[0039] As a technical optimization of this utility model, the pull plate 21 makes it easier for users to pull the extension column 6, thus increasing user convenience.

[0040] The working principle and usage process of this utility model are as follows: First, the user inserts the wire end assembly 1 into the inside of the insert frame assembly 2. Then, the spring 8 pushes the moving plate 7 to move inward. The moving plate 7 pushes the rear plate 9 to move inward. The rear plate 9 pushes the locking block 10 to move inward, so that the locking block 10 is locked inside the strip 11, which can prevent it from falling off. Then, when separation is required, the pin 17 is rotated. The pin 17 drives the rotating rod 14 to rotate. The rotating rod 14 drives the elliptical disk 15 to rotate. The elliptical disk 15 presses the moving plate 7 to the outside, so that the locking block 10 is released from the inside of the strip 11, which can facilitate separation.

[0041] In summary, the anti-detachment structure of this automotive wiring harness changes the traditional method of relying solely on its own stress for fastening. Instead, it uses a locking block 10 that is engaged inside the strip 11. This prevents the harness from detaching under accidental contact with external force, avoids interruption of connection control data, and does not affect the normal use of vehicle control.
