Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness technology, specifically an automotive wiring harness with a protective sleeve. Background Technology

[0002] Traditional automotive wiring harnesses typically use a single rubber or plastic protective sleeve to enclose the entire harness. When internal terminals need to be connected, inspected, repaired, or branched, the protective sleeve must be cut or torn to expose the internal wiring harness. However, this operation not only damages the protective sleeve but also makes it irreparable, requiring additional tape or replacement of the protective sleeve for resealing. However, temporary sealing with tape has poor sealing performance and is easily loosened by vehicle vibration and temperature changes; its strength is far inferior to the protective layer itself. Therefore, those skilled in the art have provided an automotive wiring harness with a protective sleeve to solve the problems mentioned in the background section. Utility Model Content

[0003] The purpose of this invention is to provide an automotive wiring harness with a protective sleeve to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A car wiring harness with a protective sleeve includes an input terminal. One end of the input terminal is provided with a composite rubber protective layer. The head of the composite rubber protective layer is turned outward and covers the surface of the main body. A sliding ring is slidably connected to the surface of the composite rubber protective layer. The head of the composite rubber protective layer is excessively connected to the sliding ring.

[0006] Furthermore, a main output harness is provided inside the composite rubber protective layer, with a main rectangular terminal at one end of the main output harness and the other end of the main output harness connected to the input terminal.

[0007] Furthermore, a set of single-layer rubber protective layers is provided inside the composite rubber protective layer, and a shunt wire harness is provided in the single-layer rubber protective layer. One end of the shunt wire harness is provided with a quick-release circular output terminal, and the other end of the shunt wire harness is connected to the input terminal.

[0008] Furthermore, the composite rubber protective layer contains a first sub-strand, the outer layer of which is a single layer of rubber material, and the inner layer of which includes a first small output harness, a small rectangular terminal, and a second small output harness. The first sub-strand contains the first small output harness and the second small output harness, and one end of the first and second small output harnesses is provided with a small rectangular terminal, while the other end of the first and second small output harnesses is connected to the input terminal.

[0009] Furthermore, the composite rubber protective layer is provided with tensile ropes, which are made of nylon fiber.

[0010] Furthermore, the composite rubber protective layer contains a stranded wire harness, and the stranded wire harness contains a second sub-strand. The outer layers of the stranded wire harness and the second sub-strand are both made of single-layer rubber material. The inner layer of the second sub-strand includes a first semi-circular wire harness, a plate-shaped output terminal, and a second semi-circular wire harness. The second sub-strand contains the first semi-circular wire harness and the second semi-circular wire harness arranged in parallel. One end of the first semi-circular wire harness and the second semi-circular wire harness is provided with a plate-shaped output terminal, and the other end of one end of the first semi-circular wire harness and the second semi-circular wire harness is connected to an input terminal.

[0011] By adopting the above technical solution

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The structure of the composite rubber protective layer with its head turned outward and fixedly connected to the sliding ring allows for the removal of the protective layer when the internal wire harness needs to be connected to terminals, inspected and repaired. There is no need to cut or tear the protective layer. Simply slide the sliding ring to move the head of the protective layer synchronously, quickly exposing the internal wire harness working area. This avoids damage to the protective layer and failure of sealing performance due to violent peeling, and can effectively solve the problem that the traditional wire harness protective layer cannot be restored after peeling.

[0014] 2. The composite rubber protective layer serves as the outer main protection, providing overall wear and compression resistance. The inner single-layer rubber protective layer and the sub-strand outer single-layer rubber serve as the inner subdivision protection, ensuring independent protection for each branch harness while avoiding mutual friction and loss caused by the mixing of multiple harnesses. At the same time, the inner protection of the single-layer rubber material takes into account the flexibility of the harness, adapting to the complex wiring paths inside the car, avoiding the wiring stiffness caused by excessively thick protective layers, and effectively reducing production costs through the targeted application of materials.

[0015] 3. The tensile rope made of nylon fiber is integrated into the composite rubber protective layer. By utilizing the high strength and high toughness of nylon fiber, the overall tensile strength and fatigue resistance of the wire harness are significantly improved. Attached Figure Description

[0021] To make the technical means, creative features, achieved objectives and effects of this utility model easier to understand, the present utility model is further described below in conjunction with specific embodiments. In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0022] Please see Figures 1-4 This utility model provides an embodiment of an automotive wiring harness with a protective sleeve, including an input terminal 1. One end of the input terminal 1 is provided with a composite rubber protective layer 2. The head of the composite rubber protective layer 2 is turned outward and covers the surface of the main body. A sliding ring 12 is slidably connected to the surface of the composite rubber protective layer 2. The head of the composite rubber protective layer 2 is excessively connected to the sliding ring 12. The head of the composite rubber protective layer 2 is folded outward to form a structure in which the head is turned outward and covers the main body. A sliding ring 12 that is compatible with the turned-out head is selected and fixedly connected to the turned-out head to ensure that the sliding ring 12 can slide along the outer surface of the protective layer body and can synchronously drive the turned-out head to move when sliding, so as to realize the sliding exposure and reset coverage of the protective layer.

[0023] In this embodiment, a main output harness 9 is disposed within the composite rubber protective layer 2. One end of the main output harness 9 is provided with a rectangular terminal 8, and the other end of the main output harness 9 is connected to the input terminal 1. A set of single-layer rubber protective layers 3 is disposed within the composite rubber protective layer 2. A shunt harness 4 is disposed within the single-layer rubber protective layer 3. One end of the shunt harness 4 is provided with a quick-release circular output terminal 5, and the other end of the shunt harness 4 is connected to the input terminal 1. A first sub-strand 6 is disposed within the composite rubber protective layer 2. The outer layer of the first sub-strand 6 is a single-layer rubber material, and the inner layer of the first sub-strand 6 includes a first small-strand output harness 13 and a small-strand rectangular terminal 14. The first sub-strand 6 contains a first small output harness 13 and a second small output harness 15. One end of the first small output harness 13 and the second small output harness 15 is provided with a small rectangular terminal 14. The other end of the first small output harness 13 and the second small output harness 15 is connected to the input terminal 1. An input terminal 1 that meets the requirements of automotive circuit transmission is selected, and one end of the main output harness 9, the shunt harness 4, the first sub-strand 6, and the second sub-strand 10 is fixed to the corresponding wiring position of the input terminal 1 to ensure stable conductivity. The other end of each harness is equipped with an adapter terminal to meet the needs of different connection scenarios.

[0024] In this embodiment, a tensile rope 7 is provided inside the composite rubber protective layer 2. The tensile rope 7 is made of nylon fiber. A stranded wire harness 11 is provided inside the composite rubber protective layer 2. A second sub-strand 10 is provided inside the stranded wire harness 11. The outer layers of the stranded wire harness 11 and the second sub-strand 10 are both made of single-layer rubber material. The inner layer of the second sub-strand 10 includes a first semi-circular wire harness 16, a sheet-shaped output terminal 17, and a second semi-circular wire harness 18. The first semi-circular wire harness 16 and the second semi-circular wire harness 18 are arranged side by side inside the second sub-strand 10. A sheet-shaped output terminal 17 is provided at one end of the first semi-circular wire harness 16 and the second semi-circular wire harness 18. The second semicircular wire harness 18 is connected at one end to the input terminal 1. A single-layer rubber protective tube is used to wrap the shunt wire harness 4, the first sub-strand 6, and the second sub-strand 10 respectively, forming an independent protective unit to avoid friction from multiple wire harnesses. The single-layer rubber material is flexible, adaptable to complex wiring, and reduces the amount of redundant protective material used, thus reducing costs. The wrapped inner wire harness and the nylon fiber tensile rope 7 are gathered together and covered with a composite rubber protective layer 2. The composite rubber material provides wear-resistant and compression-resistant overall protection. The tensile rope 7 is arranged along the axial direction of the protective layer, and its two ends are fixed to the input terminal 1 and the end of the protective layer respectively, forming an integrated tensile structure.

[0025] When the sliding ring 12 is in its initial position near the output terminal, the outward-folded protective layer head tightly covers the outside of the protective layer body. With the cooperation of the sliding ring 12, the tension rope 7 is kept taut, which improves the wire harness's resistance to vibration and tension, ensuring long-term stable operation. When terminal docking, inspection and maintenance are required, the sliding ring 12 is slid along the axial direction away from the input terminal 1. The sliding ring 12 drives the outward-folded head to move synchronously, gradually exposing the internal area of ​​the body and the internal wire harness, forming the working area. After the operation is completed, the sliding ring 12 is slid in the opposite direction, driving the outward-folded head back to its original position and covering the internal wire harness again. Then, the head is sealed with external tape to restore stable protection.

[0026] The composite rubber protective layer 2 has an outward-folding head that is fixedly connected to the sliding ring 12. When terminal docking, inspection, or maintenance of the internal wire harness is required, there is no need to cut or tear the protective layer. Simply sliding the sliding ring 12 can move the head of the protective layer synchronously, quickly exposing the internal wire harness working area. This avoids damage to the protective layer and failure of sealing performance due to violent peeling, effectively solving the problem of traditional wire harness protective layers being unable to be restored after peeling. The composite rubber protective layer, as the outer main protection, provides overall wear and compression resistance. The inner single-layer rubber protective layer 3 and the outer strand of the sub-strand... The single-layer rubber inner protective layer ensures independent protection for each branch harness while avoiding mutual friction and loss caused by the mixing of multiple harnesses. At the same time, the single-layer rubber inner protective layer takes into account the flexibility of the harness, adapting to the complex wiring paths inside the car, and avoiding the wiring stiffness caused by excessively thick protective layers. Furthermore, the targeted application of materials can effectively reduce production costs. The nylon fiber tensile rope 7 is integrated into the composite rubber protective layer 2. Utilizing the high strength and high toughness of nylon fibers, it significantly improves the overall tensile strength and fatigue resistance of the harness.

Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
