[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction, and therefore should not be construed as limiting this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0029] As attached Figure 1 As shown, the main technical features of this technical solution are composed of a cable reel box 2, a cable compartment shell 1, a foam cover 4, a compression screw ring 3, and irregular cables.

[0030] The irregular cable mainly includes a preferentially cured thin-end cable 5 and a post-wound cured thick-end cable 6, which are interconnected. A transducer 7 is provided in the middle of the post-wound cured thick-end cable 6, and a watertight joint 8 is provided at the end, through which it is connected to the wiring harness 10. A load-bearing plug 9 is provided at the end of the preferentially cured thin-end cable 5.

[0031] After the irregular cables are coiled, the utility model makes the irregular cables regular and neat, firmly bonded, and can achieve even laying out without tangling when laying out the cables. This irregular cable optimization layout technology improves the space utilization rate of the cables in the cabin and optimizes the space structure in the cabin.

[0032] The layout of this technical solution is mainly divided into two steps. The first step is to prioritize the curing of the thin-end cable 5. The completed state is as shown in the attached figure. Figure 3 As shown, the details are as follows:

[0033] Prepare irregular cables. The irregular cable structure diagram is as attached. Figure 2As shown, clear away debris. Before winding the cable, protect the transducer 7 on the irregular load-bearing cable with a foam sheet and secure it with a cable tie. Secure the wiring harness 10 on the irregular load-bearing cable to the load-bearing cable with blue tape. Straighten the irregular load-bearing cable and set it aside in preparation for winding. Prepare the necessary tools for winding and place them in the designated area on the workbench.

[0034] On the workbench, rotate and unscrew the end cover of the wire coiling mold; cover the shaft cylinder of the wire coiling mold with a layer of film plastic, ensuring that it evenly and flatly covers the entire shaft cylinder; rotate and screw on the end cover of the wire coiling mold, ensuring that the end cover is tightened and the film plastic is pressed and fixed.

[0035] Install the winding mold onto the winding equipment. Thread the irregular thin-end load-bearing cable through the small hole at the bottom end of the winding mold, ensuring it extends to the specified length. Start the winding equipment and wind the irregular thin-end load-bearing cable counterclockwise around the winding mold shaft, winding N turns per layer until the first layer is complete. Stop the winding equipment and evenly apply silicone rubber to each layer of cable with a brush, ensuring a thorough application and a secure bond.

[0036] Repeat the same process for the second, third, and fourth layers. After the fourth layer, apply a uniform coat of silicone rubber. Next, inspect the spool for even and complete application of silicone rubber. Verify that the protruding length of the irregular, thin-end load-bearing cable meets the specified length requirements. Verify that the spool has been wound N times per layer, for a total of M layers. After inspection, remove the winding mold from the winding equipment. Place the finished winding mold in a designated location for curing.

[0037] Two curing treatment methods: natural curing treatment, the time is not less than 48 hours; oven curing treatment, the time is not less than 24 hours.

[0038] Next, inspect the spool to ensure the silicone rubber is fully cured and securely bonded. Once this is complete, disassemble the cured cable reel mold and remove the reeled, irregular, thin-end, load-bearing cable spool. Wrap the cable's adhesive end with blue tape to prevent it from falling off.

[0039] The second step is the overall installation and assembly. The completed state is as shown in the attached Figure 1 As shown, the specific process is:

[0040] Coil the thick end of the irregular cable into the cable reel box 2. Operator A holds the solidified cable, operator B holds the wire harness 10 at the center, and operator C coils the thick end cable.

[0041] From a bird's-eye view, coil the wire in a clockwise direction inside the wire coil box 2, first coil the inner ring twice, then coil the outer ring twice.

[0042] When coiling the thick-end cable, appropriate adjustments can be made so that the transducer 7 is just in the designated area of the coil box 2.

[0043] After the thick-end cable is coiled, the solidified irregular thin-end load-bearing cable is stacked on the end surface of the coiling box 2 along the coiling direction.

[0044] Apply a layer of silicone rubber evenly on the outer diameter of the foam cover 4, hold the foam cover 4 and slowly squeeze it into the cable compartment housing 1, and adjust the foam cover 4 to ensure that it fits evenly with the wall of the cable compartment housing 1.

[0045] Apply a circle of silicone rubber evenly on the end face of the fixing screw. The operator holds the fixing screw and aligns it with the inner thread of the cable compartment shell 1. Slowly rotate the fixing screw clockwise (right-hand) to complete the installation of the cable assembly.

[0046] The coiled irregular cables are neatly arranged, firmly bonded, and can be laid out evenly without tangling. This irregular cable optimization layout technology improves the space utilization of cables in the cabin and optimizes the space structure in the cabin.

[0047] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
