Description

Technical Field

[0001] This utility model relates to the field of wire harnesses, specifically a bending-resistant wire harness. Background Technology

[0002] A wire harness acts as a bridge between two or more isolated electronic devices, enabling the flow of current and allowing various electronic components to perform their functions. It is an indispensable component in various electrical and electronic devices. As a key component connecting electronic and electrical components, the reliability and stability of wire harnesses are crucial to the operation of equipment in fields such as automobiles, communication equipment, and industrial automation.

[0003] However, current wiring harnesses still have the following drawbacks: Existing wiring harnesses typically use traditional screw-fixed connectors. These connectors require precise alignment of the socket during installation and tightening of screws after installation, making the process cumbersome, especially in confined spaces or situations requiring frequent connection and disconnection, resulting in low installation efficiency. For example, in automotive manufacturing, wiring harnesses need to connect numerous sensors and actuators. Traditional screw-fixing methods are not only time-consuming but also require highly skilled operators, making them prone to errors. They also require the use of small screws and other fasteners, and numerous screwdrivers and other tools for tightening; even small screws can easily fall out if not handled carefully. Existing wiring harness connectors lack effective anti-loosening mechanisms. During equipment operation, due to vibration, temperature changes, and other factors, connectors are prone to loosening. After prolonged use or under pulling, the connection between the connector and the external device can easily loosen or even detach, causing poor contact. Once the connector loosens, it may lead to poor contact, signal transmission interruption, or unstable current transmission, thus affecting the normal operation of the equipment. For example, in communication equipment, unstable wiring harness connections can lead to data transmission errors or communication interruptions, affecting the reliability and lifespan of the equipment.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The following is combined with Figures 1-5 A detailed description of the bending-resistant wire harness of this utility model is provided below:

[0022] A bending-resistant wire harness includes a core conductor 1, which is composed of several stranded copper wires. One end of the core conductor 1 is provided with a connecting block 4. One end of the connecting block 4 extends outward to form a connecting portion 5. A snap-fit ​​strip 6 is provided on the side of the connecting block 4. A snap-fit ​​groove 7 is provided on the surface of the snap-fit ​​strip 6. A connecting groove 8 is formed between the snap-fit ​​strip 6 and the connecting portion 5. The bottom of the connecting block 4 is recessed inward to form a bottom groove 9. The side of the connecting block 4 is recessed inward to form a positioning groove 10.

[0023] One end of the connecting block 4 is provided with a plurality of connection ports 11, and a plurality of conductive terminals 12 are provided inside the connection ports 11. One end of the wire core conductor 1 is electrically connected to the conductive terminals 12.

[0024] The outer side of the conductor core 1 is provided with several fixing sleeves 3, and the adjacent fixing sleeves 3 are arranged at equal intervals. The fixing sleeves 3 arranged at equal intervals on the outer side of the conductor core 1 can effectively protect the wire bundle, prevent the wire bundle from being scattered, and fix multiple conductor cores 1 to prevent the scattered wire bundle from being distributed messily.

[0025] The conductor core 1 is wrapped with an insulation layer 15. An inner shielding layer 16 is wrapped around the outer surface of the insulation layer 15. A tensile layer 17 is wrapped around the outer surface of the inner shielding layer 16. Several elastic cavities 18 are formed inside the tensile layer 17, each filled with a tough filler 19. An inner protective sleeve 20 is wrapped around the outer surface of the tensile layer 17. An outer shielding layer 21 is wrapped around the outer surface of the inner protective sleeve 20. A braided protective net 14, formed by weaving, is wrapped around the outer surface of the braided protective net 14. An outer protective sleeve 13 is wrapped around the outer surface of the braided protective net 14. The elastic cavities 18 are distributed circumferentially within the tensile layer 17 and are wrapped around the conductor core 1. The tough filler 19, composed of rubber-filled particles, fills the elastic cavities 18. A tensile toughness rope 2 is provided inside the insulation layer 15. The braided protective net 14 is composed of high-strength fiber and spandex yarn wound together. The outer surface of the protective sleeve 13 is coated with a waterproof coating. Both the inner protective sleeve 20 and the outer protective sleeve 13 are made of PE material. The inner shielding layer 16 and the outer shielding layer 21 are both formed by wrapping with aluminum foil. The multi-layer structure wrapped on the conductor 1 (insulation layer 15, inner shielding layer 16, tensile layer 17, inner protective sleeve 20, outer shielding layer 21, braided protective mesh 14, and outer protective sleeve 13) provides all-round protection. The insulation layer 15 ensures the electrical insulation performance of the conductor 1. The inner shielding layer 16 and the outer shielding layer 21 effectively prevent electromagnetic interference and ensure the stability of signal transmission. The elastic cavity 18 and tough filler 19 inside the tensile layer 17 can buffer and disperse the stress generated by the wire harness during bending, improving the bending resistance. The braided protective mesh 14 enhances the mechanical strength and wear resistance of the wire harness. The outer protective sleeve 13 provides additional physical protection to prevent damage to the wire harness from the external environment.

[0026] In this embodiment, the elastic cavities 18 inside the tensile layer 17 are distributed in a circular pattern and filled with rubber filler particles, which can effectively disperse the stress generated when the wire harness is bent or stretched, improve the bending and tensile resistance of the wire harness, and extend the service life of the wire harness. The tough filler 19 can absorb a large amount of energy and produce a large deformation when subjected to compression or load, thereby protecting the structure from damage. The tensile toughness rope 2 set inside the insulation layer 15 further enhances the tensile and bending resistance of the wire harness, ensuring that the wire harness will not easily break or be damaged when subjected to external force, and improving the mechanical strength and reliability of the wire harness.

[0027] In this embodiment, a bending-resistant wire harness is provided with a connecting block 4, a connecting part 5, and a snap-fit ​​strip 6, which enables the wire harness to be quickly positioned and fixed during connection, facilitating the rapid installation and connection of the wire harness. The snap-fit ​​groove 7, connecting groove 8, bottom groove 9, and positioning groove 10 further enhance the firmness of the connection, prevent the connection from loosening due to external force during use, and ensure the stability of the wire harness connection.

[0028] Specifically, the layered molding and wire harness manufacturing methods and processes in this embodiment are conventional techniques and existing technologies used by those skilled in the art, and will not be described in detail here.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
