Description

Technical Field

[0001] The utility model relates to the technical field of automobile wiring harnesses, in particular to an automobile wiring harness wear prevention device. Background Art

[0002] A wiring harness is a component that is formed by crimping contact terminals (connectors) punched out of copper material with wires and cables, and then plastic-pressing an insulator or adding a metal shell to the outside to form a connecting circuit.

[0003] However, in the prior art, the protective tube of the automobile wiring harness is generally a stretchable and elastic hose, and the fixing of such a hose is not very convenient. The two ends of the hose are easily detached, resulting in the automobile wiring harness being exposed to the outside, and losing the protective effect of the automobile wiring harness. Therefore, we propose an automobile wiring harness anti-wear device. Utility Model Content

[0004] The utility model provides a device for preventing automobile wiring harness from wearing out, which solves the above-mentioned technical problems.

[0005] The utility model solves the above-mentioned technical problem with the following solution: an automobile wiring harness wear prevention device, comprising a transversely arranged protective hose, wherein both ends of the protective hose are respectively fixedly installed with fixing rings, the inner side wall of the fixing ring is provided with a plurality of built-in grooves, a limit block is slidably installed on the inner wall of the built-in groove, the cross-section of the limit block is T-shaped, the limit block is fixedly connected to the inner wall of the built-in groove by a spring, and the limit block is connected to a limit cancellation mechanism.

[0006] Preferably, the limit canceling mechanism comprises a movable ring movably sleeved on the outer side wall of the fixed ring, the movable ring is fixedly connected to a plurality of limit blocks via steel wires, and the side wall of the fixed ring is provided with a passing groove corresponding to the steel wires.

[0007] Preferably, the side wall of the outer port of the through slot is inclined, and the transverse cross-section of the through slot is trumpet-shaped.

[0008] Preferably, the protective hose is made of elastic plastic material.

[0009] The beneficial effects of the utility model are:

[0010] By arranging fixing rings at both ends of the protective hose and arranging spring-connected installation limit blocks in the fixing rings, the limit blocks are engaged with the card slots on the matching fixing components and are fixed by the springs to achieve quick installation and fixation of the protective hose, which can prevent the protective hose from loosening and causing the automobile wiring harness to be exposed and lose its protective effect, making the installation and fixation of the protective hose easier, and the limit blocks on the same fixing ring can be controlled to cancel the card connection at the same time by the moving ring, further simplifying the installation and disassembly steps of the device and improving efficiency, and by arranging the inclined side wall of the outer end of the groove, the wear of the steel wire and the fixing ring can be reduced, the service life of the device can be extended, and the fixing effect can be guaranteed.

[0011] The above description is only an overview of the technical solution of the utility model. In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the following is a detailed description of the preferred embodiment of the utility model with the accompanying drawings.

[0018] The following is combined with Figure 1-3The principles and features of the present invention are described, and the examples given are only used to explain the present invention, and are not used to limit the scope of the present invention. The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer according to the following description and claims. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0019] like Figure 1-3 As shown, the utility model is a wear-proof device for automobile wiring harness, comprising a transversely arranged protective hose 1, the protective hose 1 is retractable and can better fit the automobile wiring harness, the two ends of the protective hose 1 are respectively fixedly installed with fixing rings 2, the inner wall of the fixing ring 2 is provided with a plurality of built-in grooves 3, the length of the built-in groove 3 is greater than the length of the limit block 4, to ensure that the limit block 4 can be completely retracted into the built-in groove 3, the inner wall of the built-in groove 3 is slidably installed with the limit block 4, the cross-section of the limit block 4 is T-shaped, the limit block 4 is fixedly connected to the inner wall of the built-in groove 3 through a spring 5, the spring 5 is movably sleeved on the outer wall of the steel wire 7, to facilitate the function of the spring 5, the limit block 4 is connected to the limit cancellation mechanism, the limit cancellation mechanism includes a movable sleeve A movable ring 6 is connected to the outer wall of the fixed ring 2, and the movable ring 6 is fixedly connected to multiple limit blocks 4 through steel wires 7. A through groove 8 corresponding to the steel wires 7 is provided on the side wall of the fixed ring 2. By pulling the movable ring 6, the corresponding limit block 4 can be indirectly driven to move through the transmission of the steel wires 7, so that the limit block 4 overcomes the force of the spring 5 and retracts into the built-in groove 3, and the connection and fixation between the limit block 4 and the corresponding component are cancelled, which is convenient and fast. The device is provided with a fixed ring 2, and a spring 5 is provided in the fixed ring 2 to connect and install the limit block 4. Through the limit block 4 and the matching fixed component, the limit block 4 is inserted into the outer wall of the fixed component with a slot, so that the device can be quickly installed and connected, which is convenient and practical.

[0020] Specifically, the side wall of the outer port of the groove 8 is inclined, the transverse cross-section of the groove 8 is trumpet-shaped, and the shape design of the groove 8 can reduce the wear of the fixing ring 2 of the steel wire 7 and extend the service life of the steel wire 7.

[0021] More specifically, the protective hose 1 is made of an elastic plastic material. The protective hose 1 has a certain elasticity and can be elastically contracted, so as to better protect the automobile wiring harness.

[0022] Working principle:

[0023] When in use, the protective hose 1 is sleeved on the outside of the automobile wiring harness, and then the movable ring 6 is pulled to move. The movable ring 6 indirectly pulls the movement of the corresponding limit block 4 through the transmission of the steel wire 7, so that the limit block 4 overcomes the force of the spring 5 and retracts into the built-in groove 3. Then the fixed ring 2 is moved, and the fixed ring 2 is combined with the corresponding fixed component, and the limit block 4 is aligned with the slot on the corresponding fixed component, and then the movable ring 6 is released, and the spring 5 pushes the limit block 4 to move and reset, and the limit block 4 extends out of the built-in groove 3 and engages with the slot on the corresponding fixed component. Repeat the above steps to fix the other end of the fixed ring 2, so as to complete the installation of the device and protect the automobile wiring harness.
