[0002] At present, there is still a phenomenon of random artificial arrangement of irregular cables in the domestic aircraft, and there is still a lack of research and application on the optimization layout of irregular cables. The existing cable layout in aircraft has the following defects due to the lack of professional process and technical guidance:

[0003] 1. Irregular cables are difficult to store effectively, occupy a large space in the aircraft cabin, and have a low space utilization rate;

[0004] 2. The cable layout is messy and difficult to organize and mark.

[0005] 3. There is a tangling problem when the cables are retracted or released. Summary of the invention

[0006] In view of this, in order to adapt to the optimized layout of various types of irregular cables in the cabin of a general-purpose aircraft, the present invention can arrange various types of irregular cables in the cabin neatly and reasonably, and retract and release them regularly and evenly, thereby optimizing the space utilization in the cabin. An irregular cable layout device and operation method are proposed.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0015] Preferably, the fixing assembly includes a compression screw ring screwed to the upper end of the cable compartment shell, and a foam cover plate arranged in the cable compartment shell and located between the irregular cable and the compression screw ring.

[0016] The present invention also provides an operation method of an irregular cable layout device, comprising the following steps:

[0017] Step 1: Coil and solidify the thin-end cables of the irregular cables;

[0018] Step 2: Wind the irregular cables and solidify the thick-end cables into the cable winding box, and stack the already solidified thin-end cables on the end surface of the cable winding box along the winding direction;

[0020] Step 4. Apply a circle of silicone rubber evenly on the end face of the fixing screw ring. The operator holds the fixing screw ring and aligns it with the inner thread of the cable compartment shell.

In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0048] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] As attached Figure 1As 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 plate 4, a compression screw ring 3, and irregular cables.

[0050] The irregular cable mainly includes a preferentially solidified thin-end cable 5 and a post-wound solidified thick-end cable 6 which are interconnected. A transducer 7 is arranged in the middle of the post-wound solidified thick-end cable 6, and a watertight joint 8 is arranged at the end thereof, which is connected to a wiring harness 10 through the watertight joint 8. A load-bearing screw plug 9 is arranged at the end of the preferentially solidified thin-end cable 5.

[0051] After the irregular cables are coiled in the present invention, the irregular cables are regular and neat, firmly bonded, and can be evenly laid out without tangling when being laid out. 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.

[0052] The layout of this technical solution is mainly divided into two steps. The first step is to preferentially solidify the thin-end cable 5. The state after the completion is as shown in the attached figure. Figure 3 As shown, the details are as follows:

[0053] Prepare irregular cables. The irregular cable structure diagram is as attached. Figure 2 As shown, clean up the debris. Before winding the cable, wrap the transducer 7 on the irregular load-bearing cable with a foam sheet for protection and tie it tightly with a cable tie; tie the wire harness 10 on the irregular load-bearing cable to the load-bearing cable with a blue tape for protection; place the irregular load-bearing cable straight and aside, and prepare for winding the cable. Prepare the tools required for winding the cable and place them in the designated position on the workbench.

[0054] 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 to ensure that it evenly covers the entire shaft cylinder; rotate and screw on the end cover of the wire coiling mold to ensure that the end cover is tightened and the film plastic is pressed and fixed.

[0055] Install the winding mold on the winding equipment. The irregular thin-end load-bearing cable passes through the small hole on the lower end of the winding mold to ensure that the irregular thin-end load-bearing cable extends to the specified length. Start the winding equipment and let the irregular thin-end load-bearing cable wind counterclockwise around the winding mold shaft. The number of single-layer winding turns is N, and the first layer is wound. Stop the winding equipment and evenly apply silicone rubber on the wound layer of cable with a brush to ensure that it is fully applied and firmly and reliably bonded.

[0056] In the same way, coil the second, third, and fourth layers. After coiling the fourth layer, evenly brush the silicone rubber on the fourth layer. Then, check whether the silicone rubber on the spool is evenly and completely applied. Whether the length of the irregular thin-end load-bearing cable meets the specified length requirements. Whether the spool is coiled with N turns of a layer, a total of M layers. After the inspection is completed, remove the coiling mold from the winding equipment. Place the coiled coiling mold in the specified position for curing.

[0057] 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.

[0058] Then, check whether the silicone rubber on the spool is completely cured and whether the spool is firmly and reliably bonded. After the inspection is completed, disassemble the cured wire coiling mold and remove the coiled irregular thin-end load-bearing cable spool. Wrap the coiled irregular thin-end load-bearing cable spool with blue tape to the solid glue end of the cable to prevent it from falling off.

[0059] The second step is the overall installation and assembly. The completed state is as shown in the attached figure. Figure 1 As shown, the specific process is:

[0060] The thick end of the irregular cable is coiled into the coil 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.

[0061] From a top view, the wire is wound clockwise in the winding box 2, first winding the inner ring twice, then winding the outer ring twice,

[0062] When the thick-end cable is coiled, appropriate adjustments can be made so that the transducer 7 is just in the designated area of ​​the coil box 2.

[0063] After the thick-end cable is coiled, the already solidified irregular thin-end load-bearing cable is stacked on the end surface of the coiling box 2 along the coiling direction.

[0064] Evenly apply a layer of silicone rubber on the outer diameter of the foam cover plate 4 , hold the foam cover plate 4 and slowly squeeze it into the cable compartment housing 1 , and adjust the foam cover plate 4 to ensure that it fits evenly with the wall surface of the cable compartment housing 1 .

[0065] A circle of silicone rubber is evenly applied on the end surface of the fixing screw ring. The operator holds the fixing screw ring and aligns it with the internal thread of the cable compartment housing 1, and slowly rotates the fixing screw ring clockwise (right-handed) to complete the installation of the cable assembly.

[0066] 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.

[0067] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
