A high-durability video harness assembly for sliding screens

Abstract

This invention proposes a high-durability video harness assembly for sliding screens, including a cable chain sleeved on the outside of the video harness. Both ends of the cable chain have fixing members for securing to the vehicle body. The fixing members have fixing structures for securing the sliding screen plug-in, OIB plug-in, or the end of the video harness. By using a cable chain, the video harness is threaded through it, and the end of the harness or its plug-in is fixed to the fixing members. This allows the harness and cable chain to move together when the sliding screen slides, reducing the risk of outer sheath wear and internal wire breakage during movement, extending the lifespan of the video harness. It also helps maintain the stability of the video harness connections, reducing contact problems caused by movement, thereby ensuring the stability and clarity of video signal transmission.

Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness technology, and in particular to a video wiring harness assembly. Background Technology

[0002] For automobiles, the wiring harness is like the neural network of the human body, and its importance and necessity are self-evident. Among them, the video wiring harness plays a crucial role in the automotive wiring harness, not only improving driving safety and convenience, but also greatly enriching the functions of in-vehicle entertainment and information services, and is an indispensable part of the automotive electrical system.

[0003] As market demands evolve, automotive functions are becoming increasingly diverse, leading to a greater need for automotive wiring harnesses, especially in vehicles with sliding screens. These vehicles require video wiring harnesses to move with the screen. Frequent movement or repeated bending and stretching of the wiring harness can cause wear on the outer sheath, breakage of internal wires, and poor contact at connections. This can result in interrupted or unstable video signal transmission, leading to issues such as flickering, distortion, or interruptions. Therefore, in automotive sliding screen structures, measures are needed to improve the durability and reliability of the wiring harnesses, particularly to reduce physical damage and maintain the stability of video cable connections.

[0004] Chinese invention application CN117416287A, published on January 19, 2024, discloses a sliding screen wiring harness connection structure and a vehicle. The connection structure includes: a first component; a support portion disposed on one side of a tube beam, with the first component slidably disposed on the support portion; a spiral wiring harness with both ends extending from the central axis of the spiral wiring harness, one end of the spiral wiring harness being connected to the first component; a tube beam disposed on one side of the support portion, with a first fixing member disposed on the tube beam for fixing the spiral wiring harness, the end of the spiral wiring harness away from the support portion being connected to the first fixing member, the spiral wiring harness extending and contracting on the plane formed by the first fixing member and the support portion, and the connection point between the spiral wiring harness and the first fixing member always being located on the central axis of the spiral wiring harness. Since both ends of the spiral wiring harness are located on the central axis of the spiral wiring harness, the spiral wiring harness is always located on the plane between the first fixing member and the support portion during the sliding process of the first component, and will not shift, thereby reducing the activity space occupied by the spiral wiring harness. However, the spiral wire harness in this invention application may cause wear on the outer sheath due to frequent movement and stretching, resulting in poor contact. Summary of the Invention

[0005] To address the aforementioned technical problems, this utility model proposes a high-durability video harness assembly for sliding screens, which solves the problem in the prior art where frequent movement and stretching of the sliding screen harness may cause wear on the harness sheath, leading to poor contact.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] A high-durability video harness assembly for a sliding screen includes a cable chain sleeved on the outside of the video harness. Both ends of the cable chain have fasteners for fixing to a vehicle body. The fasteners have fixing structures for securing the sliding screen insert, OIB insert, or the end of the video harness. This invention, by using a cable chain, allows the video harness to pass through it, while the end of the harness or its insert is fixed to the fasteners. This ensures that the harness and cable chain move together when the sliding screen slides, reducing the risk of outer sheath wear and internal wire breakage during movement, extending the lifespan of the video harness. It also helps maintain the stability of the video harness connections, reducing contact problems caused by movement, thereby ensuring the stability and clarity of video signal transmission.

[0008] Furthermore, to better limit the end of the cable harness and increase its stability, the fastener includes a connected bracket and a top cover, forming a limiting space between the bracket and the top cover for the video cable harness to pass through.

[0009] Furthermore, in order to facilitate the installation and removal of the fastener and to facilitate the passage of the video cable harness, the fastener includes a bracket and a top cover that interlock; a buckle and a buckle groove are provided between the bracket and the top cover.

[0010] Furthermore, in order to make the fixing member at this end hinged to the cable chain, one end of both the bracket and the upper cover is provided with a hinge pin that is hinged to the end of the cable chain or a pin hole for passing through the hinge pin.

[0011] Furthermore, in order to facilitate fixing the bracket to the vehicle body, the bracket is provided with a fixing plate that cooperates with the vehicle body, and the fixing plate is provided with a fixing hole.

[0012] Furthermore, in order to facilitate fixing the sliding screen plug-in to the bracket one with cable ties, the fixing structure includes a cable tie limiting hole one provided on the bracket one.

[0013] Furthermore, in order to facilitate the installation and removal of the fastener and to facilitate the passage of the video cable harness, the fastener includes a second bracket and a second cover that interlock; the second bracket and the second cover are provided with a second buckle and a second buckle groove that cooperate with each other.

[0014] Furthermore, in order to make the fixing member at this end hinged to the cable chain, one end of both the bracket two and the upper cover two is provided with a hinge pin that is hinged to the end of the cable chain or a pin hole for passing through the hinge pin.

[0015] Furthermore, in order to facilitate fixing the bracket two to the vehicle body, the bracket two is provided with a fixing plate two that cooperates with the vehicle body, and the fixing plate two is provided with fixing holes two.

[0016] Furthermore, in order to facilitate fixing the OIB plug to the bracket two with cable ties, the fixing structure includes a cable tie limiting hole two provided on the bracket two.

[0017] The beneficial effects of this utility model are:

[0018] 1. This utility model uses a cable chain to pass through the video cable harness, with both ends of the cable harness fixed. The movement of the cable harness and the cable chain reduces the risk of wear on the outer sheath and breakage of the internal wires during the movement of the video cable harness, thus extending the service life of the video cable harness. It also helps to maintain the stability of the connection of the video cable harness and reduces contact problems caused by movement, thereby ensuring the stability and clarity of video signal transmission.

[0019] 2. This utility model provides a bracket at both ends of the cable chain, with the wire harness plug fixed on the bracket to prevent shaking. The bracket is also fixedly connected to the vehicle body to prevent the wire harness and plug from shaking, further reducing the problem of poor contact caused by movement.
