Description

Technical Field

[0001] This utility model belongs to the field of automotive wiring harness technology, specifically relating to a waterproof and wear-resistant automotive wiring harness. Background Technology

[0002] As the core carrier of the electrical system, automotive wiring harnesses undertake the dual functions of power transmission and signal transmission. Among them, chassis wiring harnesses, engine compartment wiring harnesses, and door wiring harnesses are high-risk areas for wear and tear due to frequent movement or exposure to harsh environments. The direct consequences of wear and tear include short circuits and open circuits caused by insulation damage. In extreme cases, this may lead to vehicle fires or control system failures, easily causing vehicle malfunctions and creating significant safety hazards.

[0003] Most existing wear-resistant and waterproof wiring harnesses achieve their durability by increasing the thickness of the outer sheath, thus slowing down the rate of damage. However, due to the significant vibrations experienced by vehicles during operation, even with increased sheath thickness, the connection between the connector and the sheath is subjected to greater gravity and inertial forces from the harness's movement. This dramatically increases the risk of breakage at the connection point, posing a continued risk to the vehicle's electrical system. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof and wear-resistant automotive wiring harness, comprising: The wire core body is used for signal connection of the internal structure of the vehicle; The outer sheath structure wraps around the outside of the wire core body to form a complete wire bundle; Connecting connectors are fixed to both ends of the wire harness.

[0005] Preferably, the wire harness is further provided with a protective shell, which is a hollow structure and is formed by splicing together several sets of movable joints. Each set of movable joints is formed by movably connecting a first joint and a second joint.

[0006] Preferably, both ends of the first joint and the second joint are provided with ball joints, and a ring of limiting sponge is provided on the inner wall of the middle part. The diameter of the ball joint of the first joint is slightly smaller than the diameter of the ball joint of the second joint.

[0007] Preferably, the spherical connecting surface of the first joint is covered with a rubber layer.

[0008] Preferably, the junction between the wire harness and the connector is also covered with a rigid sheath.

[0009] The beneficial effects of this utility model are: By adding a rigid sheath at the connection between the outer sheath and the connector, the risk of the wiring harness breaking due to external force is effectively reduced. At the same time, during installation, a protective shell is installed on the outside of the wiring harness. The protective shell can not only change shape to follow the connection path of the wiring harness, but also fix the overall shape through the rubber damping structure set at the joint of the protective shell, effectively preventing the wiring harness from swinging up and down due to vehicle vibration, and also providing a waterproof effect.

[0010] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objectives and other advantages of this invention are realized and obtained through the structures particularly pointed out in the description and the accompanying drawings.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] like Figures 1 to 3 As shown, this embodiment provides a waterproof and wear-resistant automotive wiring harness, including: a wire core body 1, which is made of multiple strands of high-purity copper wire, has good conductivity, and can stably transmit signals required by the internal structure of the vehicle; an outer sheath structure 2, made of polyvinyl chloride (PVC) material, which is uniformly wrapped around the outside of the wire core body 1 through an extrusion process to form a complete wiring harness 4; and a connection connector 3, which is a common plug-in structure in the art, fixed at both ends of the wiring harness 4 to realize quick connection and disconnection of the wiring harness 4 from the device.

[0017] The wiring harness 4 is further equipped with a protective shell 5. The protective shell 5 is a hollow structure formed by splicing together several sets of movable joints 6. Each set of movable joints 6 is formed by the movable connection of a first joint 7 and a second joint 8. Both ends of the first joint 7 and the second joint 8 are provided with ball joints 9, and a ring of limiting sponge is provided on the inner wall of the middle part. The diameter of the ball joint 9 of the first joint 7 is slightly smaller than the diameter of the ball joint 9 of the second joint 8, so that the first joint 7 can be inserted into the ball joint 9 of the second joint 8. It has multiple degrees of freedom and can rotate flexibly like a joint, so as to bend and adjust according to the actual direction of the wiring harness. The surface of the ball joint 9 of the first joint 7 is covered with a rubber layer to increase friction. After the protective shell 5 changes to a suitable shape, it can provide a certain resistance to keep the protective shell 5 stable, prevent the wiring harness from swinging due to vibration during vehicle operation, and reduce the collision and wear of the wiring harness with other components. The junction between the wire harness 4 and the connector 3 is also covered with a rigid sheath 10, which is made of polycarbonate material. It is wrapped around the junction between the wire harness 4 and the connector 3 by injection molding, which effectively disperses external forces, reduces the gravity and inertial force of the wire harness when it swings, and thus significantly reduces the risk of the junction breaking.

[0018] In summary, during installation, the first joint 7 and the second joint 8 are first spliced ​​together at intervals to form a protective shell 5 with the same length as the wire harness 4. Then, the wire harness is passed through the hollow part of the protective shell 5, and the ball joints 9 at both ends of the protective shell 5 are cut off to expose the connectors 3 for easy insertion and removal. The limiting sponge inside the joint is placed on the surface of the hard sheath 10, which can support the middle part of the wire harness 4 and prevent the wire harness from swinging violently due to vibration during vehicle operation.
