Description

Technical Field

[0001] This utility model belongs to the field of automotive wiring harness technology, specifically relating to automotive wiring harnesses with a harness structure. Background Technology

[0002] Automotive wiring harnesses are the main network of automotive circuits and an indispensable part of the automotive electrical system. They connect various parts of the car, including the engine, braking system, lighting equipment, dashboard, doors, etc., ensuring that various electronic devices, sensors, actuators, etc. on the vehicle can function properly. Automotive wiring harnesses are composed of copper stamped contact terminals (connectors) crimped to wires and cables, and then covered with plastic insulation or an outer metal shell, bundled together to form an assembly that connects the circuit.

[0003] In the design and manufacturing process of automotive wiring harnesses, a certain length redundancy is often reserved, meaning that the actual laid length generally exceeds the minimum distance required for direct connection of various components. This design strategy reflects careful consideration: First, it aims to reserve space for possible future maintenance, repair, or component upgrades. During vehicle use, due to factors such as vibration, temperature changes, and natural wear and tear from long-term use, some parts of the wiring harness may age or become damaged, requiring replacement or repair. The reserved length redundancy ensures that even if some parts of the wiring harness are damaged, there is still sufficient length for connection, avoiding repair difficulties caused by insufficient wire length, thereby ensuring the stability and reliability of the vehicle's electrical system.

[0004] However, it's worth noting that while this design enhances the flexibility and maintainability of automotive wiring harnesses, excessively long harnesses can also present a number of challenges. The most significant problem is the disorganization and complexity of the wiring. Without careful planning and securing, excessively long harnesses can easily become tangled and intricate, affecting the cleanliness of the vehicle interior and potentially increasing the risk of insulation damage and short circuits due to friction and compression between wires. Furthermore, a chaotic wiring layout can hinder subsequent maintenance work, making it more difficult for technicians to locate faults. Utility Model Content

[0005] The purpose of this invention is to provide an automotive wiring harness with a bundled structure, aiming to address the challenges that excessively long harnesses can present, despite the enhanced flexibility and maintainability of this design. The most significant problem is the disorganization and complexity of the wiring. Without careful planning and securing, excessively long harnesses can easily become tangled and messy in the vehicle interior, affecting not only the cleanliness of the cabin but also increasing the risk of insulation damage and short circuits due to friction and compression between wires. Furthermore, a chaotic wiring layout can hinder subsequent maintenance work, making it more difficult for technicians to locate faults.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automotive wiring harness with a wire harness structure, comprising an automotive wiring harness, wherein the center end of the automotive wiring harness is wound around a winding post and wound inside a storage box, and a bearing is fixedly installed on the inner wall of the center end inside the storage box.

[0007] A winding post is fixedly installed in the inner ring of the bearing. The outer wall of the winding post near the end connected to the bearing is fixedly connected to one end of a coil spring. The other end of the coil spring is fixedly connected to the inner wall of the storage box. A cover plate is installed at the opening end of the storage box.

[0008] To seal the opening at the top of the storage box, as a preferred embodiment of the automotive wiring harness with a bundled structure of this invention, the surface of the cover plate has six through holes spaced evenly. The bottom of each through hole is connected to a recess, and a fixing pin is threaded into the interior of each through hole. The recess is located on the bottom outer wall of the cover plate. Six fixing feet are evenly spaced on the outer wall of the storage box near the upper opening. Each fixing foot mates with a recess, and the fixing pin passes through the through hole and is threaded into the fixing foot.

[0009] To isolate the coil spring at the bottom of the storage box, in a preferred embodiment of the automotive wiring harness with a bundled structure, each of the fixing feet has a protrusion at its bottom, and one side of the protrusion is fixedly mounted on the inner wall of the storage box. A partition is connected to the surface of the protrusion, and the partition is sleeved on the outer wall of the winding post.

[0010] In order to fix the winding post during use, as a preferred embodiment of the automotive wiring harness with a wire harness structure of this utility model, a ring is fixedly sleeved on the outer wall near the top of the winding post. The ring is movably installed on the inner wall of the cover plate. A bolt is threaded through the center end of the cover plate, and the bottom of the bolt is connected to the internal thread at the top of the winding post.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In use, the automotive wiring harness is pre-wound around the winding post, and then the cover plate is installed on top of the storage box. When the automotive wiring harness needs to be bundled, the bolt is removed, so that the winding post is released from its fixed relationship with the cover plate. At this time, the coil spring will coil, which will drive the winding post to rotate. When the winding post rotates, the automotive wiring harness can be wrapped around its outer wall, so that the automotive wiring harness can be bundled into the storage box. After the bundle is bundled, the bolt is reconnected to the winding post to keep the winding post in a fixed state. In this way, the above structure enables the automotive wiring harness to perform the function of bundling. Attached Figure Description

The other end of the coil spring 6 is fixedly connected to the inner wall of the storage box 2. A cover plate 3 is installed at the opening end of the storage box 2.

[0023] Preferably, the cover plate 3 has six through holes 302 evenly spaced on its surface. The bottom of each through hole 302 is connected to a recess 303. A fixing pin 301 is threaded into the inside of each through hole 302. The recess 303 is located on the bottom outer wall of the cover plate 3. Six fixing feet 203 are evenly spaced on the outer wall of the storage box 2 near its upper opening. Each fixing foot 203 mates with a recess 303. The fixing pin 301 passes through the through hole 302 and is threaded into the fixing foot 203. A protrusion 201 is provided at the bottom of each fixing foot 203. One side of the protrusion 201 is fixedly installed on the inner wall of the storage box 2. A partition 202 is connected to the surface of the protrusion 201, and the partition 202 is fitted onto the outer wall of the winding post 5.

[0024] The partition 202 is made of flexible rubber. The center end of the partition 202 is placed on the winding post 5. Then the partition 202 is squeezed and deformed so that the partition 202 passes through the six fixing feet 203. Then the partition 202 is released so that the bottom of the partition 202 rests on the six protrusions 201, thus completing the installation of the partition 202. When in use, the partition 202 can isolate the coil spring 6 from the automotive wiring harness 1.

[0025] When the cover plate 3 is connected to the storage box 2, the six notches 303 at the bottom of the cover plate 3 are connected to the six fixing feet 203 on the inner wall of the storage box 2. After the connection is completed, the fixing pin 301 is passed through the through hole 302 and connected to the fixing feet 203. In this way, the cover plate 3 will be fixedly installed on the storage box 2.

[0026] A ring 7 is fixedly fitted on the outer wall near the top of the winding post 5. The ring 7 is movably installed on the inner wall of the cover plate 3. A circular hole is opened at the bottom center of the cover plate 3 to connect with the winding post 5, and an annular groove is also provided at the top of the circular hole to connect with the ring 7. The ring 7 is made of flexible rubber. The ring 7 will deform when it passes through the circular hole, so that the ring 7 can be smoothly installed into the position of the annular groove.

[0027] A bolt 8 is threaded through the center end of the cover plate 3, and the bottom of the bolt 8 is connected to the internal thread at the top of the winding post 5.
