Description

Technical Field

[0001] The utility model relates to the technical field of wire harness fixing, in particular to a wire harness side-by-side installation and fixing module. Background Technique

[0002] The internal wire harnesses of aircraft and multi-rotor aircraft need to be fixed using cable ties. In order to better route and fix the bundled wire harnesses, cable tie mounts are required to connect the cable ties to the inner wall or structural components of the aircraft. There are two conventional fixing methods for cable tie mounts. One is the glue bonding method, and the other is the installation using sheet metal buckles for snap connection. The cable ties installed by the above two methods can only fix one wire harness at a time. Moreover, when the wire harness needs to be removed, more or less irreversible damage will be caused to the internal sheet metal or some plastic parts of the aircraft, thereby affecting the strength of the internal structure of the aircraft and flight safety.

[0003] Therefore, it is necessary to provide a wire harness side-by-side installation and fixing module to solve the above technical problems. Summary of the Utility Model

[0004] In view of the above situation, to overcome the defects of the prior art, the utility model provides a wire harness side-by-side installation and fixing module that can fix multiple wire harnesses at one time and will not affect the structural strength of the aircraft when the wire harness is removed.

[0005] To achieve the above object, the technical solution adopted by the utility model is as follows:

[0006] The wire harness side-by-side installation and fixing module includes: an installation frame, on which a plurality of fixing mechanisms are installed side by side. Two buckles are installed at the bottom of the installation frame, and the buckles are clamped on the sheet metal parts inside the aircraft. A plurality of wire harnesses are separately fixed on the corresponding fixing mechanisms, so that multiple wire harnesses are evenly separated inside the aircraft, and the wiring is more beautiful, which is convenient for subsequent maintenance. Installation grooves are opened on both sides of the installation frame. The fixing mechanism includes a bottom plate, and both sides of the bottom plate are clamped in the installation grooves and can slide along the installation grooves. A fixing column is installed in the middle of the bottom plate, and a limiting hole is opened on the fixing column. A cable tie is installed at the top of the fixing column. One end of the cable tie passes through the limiting hole. A reverse-preventing structure similar to the head of the cable tie is provided in the limiting hole, which will not be elaborated here. The cable tie can only pass through the limiting hole unidirectionally. The cable tie goes around the wire harness once to bundle the wire harness. Limiting plates are installed on both sides of the installation frame, and both sides of the limiting plates are also inserted into the installation grooves. The limiting plates limit the fixing mechanisms on the installation frame.

[0007] Preferably, a plurality of reinforcing ribs are installed between the bottom plate and the fixing column. The reinforcing ribs are triangular and evenly arranged.

[0008] Preferably, structural plates are installed on both sides of the bottom plate. During the sliding contact between the structural plates and the installation grooves, they have higher structural strength.

[0009] Preferably, the buckle includes a U-shaped card slot and a connecting member fixedly connected. The connecting member is connected to the connecting screw, that is, the connecting member is connected to the mounting frame. A plurality of elastic plates are obliquely installed in the card slot, and the bottom of the elastic plate is inclined toward one side of the bottom of the card slot.

[0010] Preferably, both the mounting frame and the fixing mechanism are made of nylon material, specifically PA66 material.

[0011] Preferably, the middle part of the buckle (bottom plate, fixing column, reinforcing rib) is made of medium carbon steel material, and the outer layer is made of PA66 material.

When maintaining or disassembling the wire harness, the wire harness can be conveniently disassembled without disassembling the buckle, and it will not damage the internal structure of the aircraft and will not affect the structural strength of the aircraft;

[0014] (2) By arranging a plurality of reinforcing ribs between the bottom plate and the fixing column, the utility model can improve the structural strength between the bottom plate and the fixing column;

At the bottom of the installation frame 1, two buckles 2 are installed, and the buckles 2 are stuck on the sheet metal part 4 inside the aircraft. A plurality of wire harnesses 5 are separately fixed on the corresponding fixing mechanisms 3, so that multiple wire harnesses are evenly separated inside the aircraft, making the wiring more beautiful and facilitating subsequent maintenance. Installation slots are opened on both sides of the installation frame 1. The fixing mechanism 3 includes a bottom plate 6, and both sides of the bottom plate 6 are clamped in the installation slots and can slide along the installation slots. A fixing column 7 is installed in the middle of the bottom plate 6, and a limiting hole 8 is opened on the fixing column 7. A cable tie 9 is installed on the top of the fixing column 7. One end of the cable tie 9 passes through the limiting hole 8. There is an anti-backward structure similar to the head of the cable tie in the limiting hole 8, which will not be elaborated here. The cable tie 9 can only pass through the limiting hole 8 unidirectionally. The cable tie 9 goes around the wire harness 5 once, thereby bundling the wire harness 5. Limiting plates 15 are installed on both sides of the installation frame 1, and both sides of the limiting plates 15 are also inserted into the installation slots. The limiting plates 15 limit the fixing mechanisms 3 on the installation frame 1. During use, the buckles 2 are stuck on the sheet metal part 4 inside the aircraft, and a plurality of wire harnesses 5 are separately fixed on the corresponding fixing mechanisms 3, so that multiple wire harnesses are evenly separated inside the aircraft, making the wiring more beautiful and facilitating subsequent maintenance. It avoids the possible friction or the possibility of leakage and short circuit caused by the cross-installation of the wire harness 5, and is safer to use. Unscrew the connection screw 16 between the limiting plate 15 and the installation frame 1, release the fixation of the limiting plate 15, and then pull the limiting plate 15 outward to remove the limiting plate 15 from the installation frame 1, and then the corresponding wire harness 5 can be removed, which is convenient for replacing the wire harness 5. When removing, there is no need to disassemble the buckle 2, so it will not cause damage to the sheet metal part 4, will not damage the internal structure of the aircraft, and will not affect its structural strength.

[0028] By setting the installation frame 1, the buckles 2 and the fixing mechanism 3 including the bottom plate 6, the fixing column 7, the limiting hole 8 and the cable tie 9, and using the limiting plates 15 to limit both sides of the fixing mechanism 3, it is possible to fix a plurality of cable ties evenly at the same time, which is more beautiful and convenient for maintenance. When maintaining or disassembling the wire harness 5, there is no need to disassemble the buckle 2, and the wire harness 5 can be easily disassembled, which will not damage the internal structure of the aircraft and will not affect the structural strength of the aircraft.

[0029] Embodiment 2:

[0030] As Figure 5 shown, a plurality of reinforcing ribs 10 are installed between the bottom plate 6 and the fixing column 7. The reinforcing ribs 10 are triangular and are evenly arranged. Through the reinforcing ribs 10, the structural strength and connection stability between the bottom plate 6 and the fixing column 7 are improved, and thus the cable tie 9 is more stable. Therefore, the wire harness 5 tied by the cable tie is also more stable.

[0031] By arranging a plurality of reinforcing ribs 10 between the bottom plate 6 and the fixing column 7, the structural strength between the bottom plate 6 and the fixing column 7 can be improved.

[0032] Embodiment 3:

[0033] As Figure 5 shown, structural plates 11 are installed on both sides of the bottom plate 6. During the process of the structural plates 11 slidingly contacting the installation grooves, they have higher structural strength, can improve the anti-deformation ability of the bottom plate 6, make it not easy for both sides of the bottom plate 6 to deform, and make it not easy for the bottom plate 6 to be disengaged from the installation grooves.

[0034] By arranging the structural plates 11 on both sides of the bottom plate 6, the anti-deformation ability of the bottom plate 6 can be improved, and it is not easy for the bottom plate 6 to be disengaged from the installation grooves.

[0035] Embodiment 4:

[0036] As Figure 4 shown, the buckle 2 includes a U-shaped card slot 12 and a connecting member 14 which are fixedly connected. The connecting member 14 is connected to the connecting screw 16, so that the connecting member 14 is connected to the installation frame 1. A plurality of elastic plates 13 are inclinedly installed in the card slot 12, and the bottom of the elastic plates 13 inclines towards the bottom side of the card slot 12. During use, the connecting screw 16 passes through the limiting plate 15 and the through hole on the installation frame 1 and is screwed into the threaded hole on the connecting member 14, thereby connecting the installation frame 1, the limiting plate 15 and the connecting member 14 into one body, and then fixing the card slot 12 at the bottom of the installation frame 1. The buckle of the card slot 12 is engaged with the sheet metal part 3, so that the sheet metal part 4 enters the card slot 12, and the elastic plates 13 are pressed by the sheet metal part 4 and bent towards both sides. Through the elasticity of the sheet metal part 4, the card slot 12 is clamped with the sheet metal part 4.

[0037] By arranging the card slot 12, the elastic plates 13 and the connecting member 14, the buckle 2 can be conveniently fixed at the bottom of the installation frame 1, and the buckle 2 can be conveniently clamped with the sheet metal part 4.

[0038] Embodiment 5:

[0039] Both the installation frame 1 and the fixing mechanism 3 are made of nylon material, specifically PA66 material, which is made by polycondensation of adipic acid and hexamethylenediamine. It has high mechanical strength, excellent wear resistance and self-lubrication, as well as good heat resistance. Therefore, the installation frame 1 and the fixing mechanism 3 have a longer service life, are less affected by the high temperature inside the aircraft, are not easy to deform, and have low cost, and are very suitable for popularization and use.

[0040] By arranging the installation frame 1 and the fixing mechanism 3 made of PA66 material, the cost can be reduced and it is suitable for use.

[0042] The middle part of the buckle 2 (base plate 6, fixed column 7, and reinforcing rib 10) is made of medium carbon steel material, and the outer layer is made of PA66 material, which has higher structural strength. When connecting with the sheet metal part 4, it is more stable and not easy to deform.

[0043] By setting the buckle 2 with the middle part made of medium carbon steel material and the outer layer made of PA66 material, the structural rigidity of the buckle 2 can be improved, and its anti-deformation ability can be enhanced while being insulated.

[0044] Working principle: During use, the buckle 2 is clamped on the sheet metal part 4 inside the aircraft. Multiple wire harnesses 5 are separately fixed on the corresponding fixing mechanism 3, so that multiple strands of wire harnesses are evenly separated inside the aircraft, making the wiring more beautiful and facilitating subsequent maintenance. It avoids the possible friction or the possibility of leakage and short circuit caused by the cross-installation of the wire harness 5, and is safer to use. Unscrew the connecting screw 16 between the limit plate 15 and the mounting frame 1 to release the fixation of the limit plate 15, and then pull the limit plate 15 outward to remove the limit plate 15 from the mounting frame 1, then the corresponding wire harness 5 can be removed, which is convenient for replacing the wire harness 5. When removing, there is no need to disassemble the buckle 2, so it will not cause damage to the sheet metal part 4, will not damage the internal structure of the aircraft, and will not affect its structural strength.
