This method mainly corresponds to the bundling of single-strand wire harnesses. Another method is as follows Figure 2 As shown, the bundling assembly includes a second cable tie 8, two third cable ties 9 and a connector 10, wherein the second cable tie 8 and the two third cable ties 9 are connected by the connector 10, the second cable tie 8 passes through the cross insertion hole 6 and is connected to the cable tie connecting seat 3, and the two third cable ties 9 separately bundle the two wire harnesses that need to be isolated, thereby achieving the requirement of using one fixing mechanism 1 to bundle the two wire harnesses at the same time. The fixing mechanism 1 and the bundling assembly are both made of flame-retardant nylon material. When in use, the multi-purpose fixing base 4 can be clamped on the structural parts inside the aircraft by the clamp 5, or the clamp 5 can be removed and the multi-purpose fixing base 4 can be directly pasted to the inside of the aircraft with glue, and then the first cable tie 2 or the third cable tie 9 is used to bundle the wire harness according to the amount of the wire harness. The following takes the bundling of two isolated wire harnesses as an example. Select the horizontal or vertical direction, pass the second cable tie 8 through the cross insertion hole 6, and connect it to the cable tie connecting seat 3. The two third cable ties 9 are used to separately bundle the two wire harnesses that need to be isolated, so that the two wire harnesses are fixed in one position (the same fixing mechanism) and leave a certain distance between each other. Then the cable tie connecting seat 3 and the multi-purpose fixing base 4 are plugged in. If the wire harness needs to be removed, unplug the cable tie connecting seat 3 from the multi-purpose fixing base 4, and then remove the bundling assembly. The wire harness can be easily removed to facilitate reorganization of the wire harness. Therefore, for the internal wiring harness of the aircraft, it can be fixed by pasting or clamping, and the clamping piece (clamp 5) is made of nylon material, which causes less damage to the structural parts and can bundle two wiring harnesses separately at the same time, which can meet more application scenarios and has stronger functionality.

[0030] By providing a fixing mechanism 1 including a plug-in cable tie connector 3, a multi-purpose fixing base 4 and a clamp 5, and a bundling assembly including a second cable tie 8, two third cable ties 9 and a connector 10, a suitable method can be selected to bundle and fix the wire harness, and two isolated wire harnesses can be bundled separately at the same time, which makes it more convenient to use and has more application scenarios.

[0031] Embodiment 2:

[0032] like Figure 2-4 and Figure 7As shown, a square card slot 11 is provided at the bottom of the cable tie connection base 3, and card holes 12 are provided around the card slot 11. The top of the multi-purpose fixed base 4 is inserted into the card slot 11, and two card components are provided on the multi-purpose fixed base 4. Specifically, the card components include mounting cavities 16 provided on both sides of the multi-purpose fixed base 4, the mounting cavities 16 are provided with card buttons 13, and the card buttons are provided with card joints 14, and the pressing portion of the card button 13 and the card joints 14 extend to the multi-purpose fixed base 4. A return spring 15 is installed between the buckle button 13 and the inner wall of the installation cavity 16. When in use, the slot 11 at the bottom of the cable tie connecting seat 3 is aligned with the top of the multi-purpose fixed base 4 and buckled, so that the clamping joint 14 slides into the clamping hole 12, and then the cable tie connecting seat 3 and the multi-purpose fixed base 4 are clamped. If the buckle button 13 is pressed to shrink the return spring 15, the clamping joint 14 is retracted into the installation cavity 16, and then the clamping connection between the cable tie connecting seat 3 and the multi-purpose fixed base 4 is released, making it convenient to remove the cable tie connecting seat 3.

[0033] By providing the card slot 11, the card hole 12, the buckle button 13, the card joint 14 and the return spring 15, the cable tie connecting seat 3 and the multi-purpose fixed base 4 can be conveniently carded.

[0034] Embodiment 3:

[0035] like Figure 3-6 As shown, a sliding groove 17 is provided at the bottom of the multi-purpose fixed base 4, and limiting grooves 18 are provided on both sides of the sliding groove 17. Limiting rods 19 are installed on both sides of the chuck 5, and anti-slip teeth 20 are provided on the top of the chuck 5. The limiting rods 19 on both sides of the chuck 5 are aligned with the sliding groove 18 and slid in to make the chuck 5 enter the sliding groove 17, and the clamping part of the chuck 5 faces inward. The two chucks 5 can be clamped on the light sheet metal, composite materials and other structures of the aircraft that are easily damaged or stress-concentrated and need to pass the line. The anti-slip teeth 20 are in contact with the top of the sliding groove 18, making it difficult to move in the sliding groove 18.

[0036] By providing the sliding groove 17 , the limiting groove 18 , the limiting rod 19 and the anti-slip teeth 20 , the clamp 5 can be conveniently installed on the bottom of the multi-purpose fixed base 4 .

[0037] Embodiment 4:

[0038] like Figure 4-5 As shown, a plurality of limit strips 21 are obliquely installed at the top of the sliding groove 17, and the bottom of the limit strip 21 is inclined inward. When the chuck 5 enters the sliding groove 17, the anti-slip teeth 20 on its top push the limit strip 21 to bend and deform. When the chuck 5 stops, the limit strip 21 recovers under the action of its own stress, so that its bottom end is stuck in the bottom of the anti-slip teeth 20, thereby limiting the chuck 5, so that the chuck 5 will not slide outward easily, thereby preventing the chuck 5 from loosening.

[0039] By arranging a limit strip 21 to be obliquely installed at the top of the sliding groove 17 and utilizing the cooperation between the limit strip 21 and the anti-slip teeth 20 , the position of the chuck 5 is further limited, thereby preventing the chuck 5 from loosening.

[0040] Embodiment 5:

When the anti-slip teeth 22 come into contact with an object, the friction resistance is greater and it is not easy to detach from the object, thereby making the chuck 5 more stable when clamped on the surface of the object.

[0042] By providing the anti-slip teeth 22 on the clamping portion of the clamp 5 , the clamp 5 can be clamped on the surface of the object more stably.

[0043] Embodiment 6:

[0044] like Figure 3-5 As shown, a glue injection hole 23 is opened on the multi-purpose fixed base 4, and the glue injection hole 23 is connected to the sliding groove 17. When the chuck 5 is not needed, the multi-purpose fixed base 4 only needs to be placed at the required pasting position so that the bottom sliding groove 17 faces the pasting position, and the glue is injected into the sliding groove 17 from the glue injection hole 23, and the multi-purpose fixed base 4 is pasted, thereby facilitating the glue injection.

[0045] By providing the multi-purpose fixing base 4 with the glue injection hole 23 , the multi-purpose fixing base 4 can be conveniently glued and pasted.

[0046] Working principle: When in use, the multi-purpose fixed base 4 is clamped on the structural part inside the aircraft through the clamp 5, or the clamp 5 can be removed, and the multi-purpose fixed base 4 is directly pasted inside the aircraft with glue, and then the first cable tie 2 or the third cable tie 9 is used to bundle the wire harness according to the amount of wire harness;

[0047] Take the bundling of two isolated wire harnesses as an example. Select the horizontal or vertical direction, pass the second cable tie 8 through the cross insertion hole 6, and connect it to the cable tie connector 3. The two third cable ties 9 are used to separately bundle the two wire harnesses that need to be isolated, so that the two wire harnesses are fixed in one position, and a certain distance is left between the wire harnesses. Then the cable tie connector 3 is plugged into the multi-purpose fixed base 4. If the wire harness needs to be removed, unplug the cable tie connector 3 from the multi-purpose fixed base 4, and then remove the bundling assembly. The wire harness can be easily removed to facilitate reorganization of the wire harness. For the internal wire harness of the aircraft, it can be fixed by pasting or clamping, and the clamp 5 is made of nylon material, which causes less damage to the structural parts. The two wire harnesses can be bundled separately at the same time, meeting the needs of more application scenarios and being more functional.
