AI Technical Summary
The existing double-hole fixing clip structure is not secure on one side when fixing wire harnesses, which causes the wire harness to change its direction.
The system employs a combination of a first anti-reverse pin and a second anti-reverse pin. The first anti-reverse pin engages with the mounting hole via anti-reverse teeth, while the second anti-reverse pin engages with the mounting hole via an elastic anti-reverse plate. Together, they restrict the rotation of the fixing pin and the holding force in the vertical direction.
It improves the reliability of the wire harness after fixing, prevents changes in the wire harness direction, and ensures that the fixing clips are stably installed on the sheet metal surface.

Abstract
Description
Technical Field
[0001] This application belongs to the field of wire harness fixing technology, specifically relating to a fixing clip, a wire harness fixing device, and a vehicle. Background Technology
[0002] Currently, wire harnesses are mostly secured to sheet metal using single-hole or double-hole fixing screws. Single-hole fixing screws only restrict the movement of the wire harness on the sheet metal surface and in the direction perpendicular to the surface, but they cannot restrict rotation around the surface. Double-hole fixing screws overcome these shortcomings of single-hole fixing screws.
[0003] The existing double-hole fixing clips have one clip for sheet metal fixation, providing holding force; the other clip is an anti-rotation positioning pin, which is inserted into a positioning hole in the sheet metal and held in place by friction to restrict the degree of freedom of rotation about a direction perpendicular to the sheet metal surface, thus ensuring that the double-hole fixing clip does not rotate on the sheet metal surface. However, in actual use, it has been found that when fixing wire harnesses with this double-hole fixing clip structure, when the wire harness is subjected to excessive force, the anti-rotation point cannot provide holding force perpendicular to the sheet metal surface, resulting in vertical movement on that side, increased sway, and insecure fixation on one side, thus causing changes in the wire harness orientation. Utility Model Content
[0004] The purpose of this application is to provide a fixing clip, a wire harness fixator, and a vehicle to solve the problem that when fixing wire harnesses with a double-hole fixing clip structure in the prior art, the fixation on one side is not reliable, which leads to changes in the direction of the wire harness.
[0005] To achieve the above objectives, the first aspect of this application provides a fixing clip, comprising:
[0006] A connector, wherein a fixing part is provided on the connector;
[0007] The first anti-reverse pin includes a first insert rod and anti-reverse teeth. The first insert rod is disposed on the fixed part, and the anti-reverse teeth are provided on the outer peripheral surface of the first insert rod.
[0008] The second anti-reverse pin includes a second insert rod and an elastic anti-reverse plate. The second insert rod is disposed on the fixed part, and the elastic anti-reverse plate is provided on the outer peripheral surface of the second insert rod.
[0009] In some embodiments, the anti-reverse locking tooth is frustoconical in shape, and the anti-reverse locking tooth has a top end and a bottom end along the length direction of the first insert rod. The bottom end is arranged facing the fixing part, and the top end is arranged away from the fixing part. The diameter of the top end is smaller than the diameter of the bottom end.
[0010] In some embodiments, the first insertion rod is provided with a plurality of anti-reverse teeth along its length.
[0011] In some embodiments, the end of the first insertion rod is provided with a guide cone, the maximum diameter of which is smaller than the maximum diameter of the anti-reverse tooth.
[0012] In some embodiments, the first anti-reverse pin further includes an elastic compression member disposed at the root of the first insertion rod;
[0013] The elastic extrusion member undergoes elastic deformation when subjected to extrusion along the length direction of the first insertion rod.
[0014] In some embodiments, a plurality of elastic anti-reverse plates are provided, and the plurality of elastic anti-reverse plates are spaced apart around the axis of the second insert rod;
[0015] One end of the elastic anti-reverse plate is connected to the second insert rod, and the other end extends obliquely toward the connecting body.
[0016] In some embodiments, the elastic anti-reverse plate has an anti-reverse notch at one end near the fixing portion.
[0017] In some embodiments, the length of the first anti-reverse pin is L1, and the length of the second anti-reverse pin is L2, wherein L1 = L2, L1 < L2, or L1 > L2.
[0018] In some embodiments, the interference fit allowance between the first anti-reverse pin and the corresponding mounting hole is greater than or equal to 1 mm; and / or, the maximum extrusion amount of the second anti-reverse pin is 1 mm and the interference fit allowance with the corresponding mounting hole is greater than or equal to 1.4 mm.
[0019] To achieve the above objectives, a second aspect of this application provides a wire harness fixator, including a fixing structure for fixing the wire harness and a fixing clip according to the first aspect, wherein the fixing structure is disposed on the connector.
[0020] To achieve the above objectives, a third aspect of this application provides a vehicle including a wiring harness retainer provided according to the second aspect above.
[0021] Through the above technical solution, the fixing clip provided in this application has at least the following technical effects.
[0022] The fixing clip provided in this application can be applied to wire harness retainers. During wire harness installation, the fixing clip secures the wire harness using its fixing structure. The fixing clip is then fixedly installed in corresponding mounting holes on the vehicle's sheet metal parts. The fixing clip has a first anti-reverse pin and a second anti-reverse pin. During installation, both the first and second anti-reverse pins are inserted into their respective mounting holes, thereby restricting the overall rotation of the fixing clip on the sheet metal surface. Furthermore, the anti-reverse teeth on the first anti-reverse pin, after pressing through the mounting hole, prevent the first anti-reverse pin from retracting. The elastic anti-reverse plate on the second anti-reverse pin is inserted into its corresponding mounting hole. Due to compression, it jams the opening of the mounting hole, thus restricting the second anti-reverse pin from retracting. Moreover, the elastic compression ensures that the second anti-reverse pin remains stably in the mounting hole. Thus, through the anti-reverse cooperation of the first and second anti-reverse pins, rotation of the fixing clip relative to the sheet metal surface is prevented, and a holding force perpendicular to the sheet metal surface is provided. Therefore, when applied to wire harness retainers, this improves the reliability of the wire harness after fixation and prevents changes in the wire harness's orientation.

[0032] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.
[0033] The technical solution of this application is described in detail below with reference to the accompanying drawings.
[0034] Example 1
[0035] like Figure 1 and Figure 2 As shown, this embodiment provides a fixing clip that can be used in a wire harness holder to secure the wire harness. It can also be used to secure conduits.
[0036] In this embodiment, the fixing pin includes a connecting body 1, a first anti-reverse pin 2, and a second anti-reverse pin 3. The connecting body 1 is provided with a fixing part 11, and the first anti-reverse pin 2 and the second anti-reverse pin 3 are arranged side by side on the fixing part.
[0037] When the fixing clip is in use, the first anti-reverse pin 2 and the second anti-reverse pin 3 need to be inserted into the corresponding mounting holes. The first anti-reverse pin 2 and the second anti-reverse pin 3 can form an anti-reverse fit with the mounting holes in the corresponding mounting holes, that is, to prevent the first anti-reverse pin 2 and the second anti-reverse pin 3 from exiting the corresponding mounting holes, so that the entire fixing clip is installed more stably.
[0038] It is understandable that the distance between the first anti-reverse pin 2 and the second anti-reverse pin 3 can be designed to be different depending on the actual situation. Therefore, in this embodiment, the size of the distance between the first anti-reverse pin 2 and the second anti-reverse pin 3 is not limited.
[0039] Optionally, the connector 1, the first anti-reverse pin 2, and the second anti-reverse pin 3 are integrally molded structures, for example, integrally injection molded.
[0040] The aforementioned first anti-reverse pin 2 includes a first insert 21 and anti-reverse teeth 22. The first insert 21 is disposed on the fixing part 11, and at least one anti-reverse tooth 22 is provided on the outer peripheral surface of the first insert 21. In this embodiment, taking multiple anti-reverse teeth 22 as an example, the multiple anti-reverse teeth 22 are distributed at intervals along the length direction of the first insert 21.
[0041] Understandably, the anti-reverse tooth 22 has a certain degree of flexibility, and its outer diameter is larger than the diameter of the mounting hole. This ensures that the anti-reverse tooth 22 can pass smoothly through the mounting hole. Specifically, when the anti-reverse tooth 22 passes through the mounting hole, its periphery is compressed and contracts. After the anti-reverse tooth 22 has completely passed through the mounting hole, it expands. The diameter of the expanded anti-reverse tooth 22 is larger than the diameter of the mounting hole, thereby preventing the first anti-reverse pin 2 from exiting the mounting hole and achieving the anti-reverse function.
[0042] It should also be noted that, since the sheet metal with mounting holes has different thicknesses, in order to ensure that the first anti-reverse pin 2 can be adapted to the base with different thicknesses, multiple anti-reverse teeth 22 are arranged at intervals along the length of the first insert 21 for adaptation, ensuring that at least one anti-reverse tooth 22 can completely pass through the mounting hole.
[0043] The aforementioned second anti-reverse pin 3 includes a second insert 31 and an elastic anti-reverse plate 32. The second insert 31 is disposed on the fixing part 11, and the elastic anti-reverse plate 32 is provided on the outer peripheral surface of the second insert 31.
[0044] Specifically, multiple elastic stop plates 32 can be provided, and the multiple elastic stop plates 32 are distributed at intervals around the axis of the second insert rod 31. One end of the elastic stop plate 32 is connected to the second insert rod 31, and the other end extends obliquely toward the connecting body 1.
[0045] Understandably, since the elastic anti-reverse plate 32 is connected to the second insert rod 31 at only one end, and the other end extends obliquely without being connected to the second insert rod 31, a certain angle will be formed between the elastic anti-reverse plate 32 and the second insert rod 31. This angle is acute, thus the entire second anti-reverse pin 3 is arrow-shaped. Before use, i.e., in the initial state, the elastic anti-reverse plates 32 around the second insert rod 31 are in an open state, and the maximum diameter formed by the multiple elastic anti-reverse plates 32 is larger than the diameter of the mounting hole. When the second anti-reverse pin 3 is inserted into the corresponding mounting hole, the elastic anti-reverse plates 32 circumferentially of the second insert rod 31 are subjected to radial compressive force along the second insert rod 31. The elastic anti-reverse plates 32 will undergo elastic deformation and move closer to the second insert rod 31, thereby reducing the diameter of the elastic anti-reverse plates 32 circumferentially of the second insert rod 31 so that the second anti-reverse pin 3 can be inserted into the corresponding mounting hole. At this time, the elastic anti-reverse plates 32 and the opening of the mounting hole form a snap-fit engagement to restrict the withdrawal of the second anti-reverse pin 3 and realize the anti-reverse function.
[0046] Thus, when the fixing clips provided in this application are used to fix wire harnesses, since both the first anti-reverse clip 2 and the second anti-reverse clip 3 have an anti-reverse function, they provide a holding force perpendicular to the sheet metal surface (i.e., the retraction direction of the first anti-reverse clip 2 and the second anti-reverse clip 3). Furthermore, through the cooperation of the first anti-reverse clip 2 and the second anti-reverse clip 3, the rotation of the fixing clips relative to the sheet metal surface can be prevented. Therefore, when applied to wire harness fixation devices, the reliability of the wire harness after fixing can be improved, and changes in the wire harness orientation can be avoided.
[0047] To more clearly describe the technical solution of this application, the fixing clips provided in this embodiment are described in detail below:
[0048] In this embodiment, the anti-reverse locking tooth 22 is frustoconical in shape, and has a top end and a bottom end along the length direction of the first insertion rod 21. The bottom end of the anti-reverse locking tooth 22 faces the fixing part 11, and the top end of the anti-reverse locking tooth 22 faces away from the fixing part 11. The diameter of the top end is smaller than the diameter of the bottom end. That is to say, the anti-reverse locking tooth 22 has an inverted frustoconical structure, which provides a certain guiding effect for insertion into the mounting hole.
[0049] Optionally, the multiple anti-reverse teeth 22 are distributed at equal intervals along the length direction of the first insert 21. In this embodiment, the multiple anti-reverse teeth 22 are arranged in a stacked manner.
[0050] Furthermore, the end of the first insertion rod 21 is provided with a guide cone 23, the maximum diameter of which is smaller than the maximum diameter of the anti-reverse retaining tooth 22. The guide cone 23 can provide guidance for the first insertion rod 21 to be inserted into the mounting hole.
[0051] Optionally, the interference fit allowance between the first anti-reverse pin 2 and the corresponding mounting hole is greater than or equal to 1 mm. Preferably, it is 1 mm. For example, the diameter of the first anti-reverse pin 2 is D1, and the diameter of the mounting hole it matches is d1, D1-d1=1 mm, thereby ensuring that the first anti-reverse pin 2 does not fall out after being inserted into the mounting hole.
[0052] In this embodiment, the first anti-reverse pin 2 further includes an elastic pressing member 24, which is disposed at the root of the first insertion rod 21 and connected to the fixing part 11. The elastic pressing member 24 generates elastic potential energy when compressed along the length direction of the first insertion rod 21. Thus, when the first anti-reverse pin 2 is inserted into the mounting hole and abuts against the surface of the sheet metal, the elastic pressing member 24 undergoes elastic deformation due to the compression. At this time, the elastic pressing member 24 possesses elastic potential energy, which allows the elastic pressing member 24 and the anti-reverse teeth 22 passing through the mounting hole to jointly clamp the sheet metal, ensuring that the first anti-reverse pin 2 does not loosen after installation.
[0053] Optionally, the elastic extrusion member 24 is an elastic cover, which on one hand presses against the sheet metal surface, and on the other hand seals the mounting holes on the sheet metal to prevent dust from entering. Of course, in some embodiments, the elastic extrusion member 24 can also be an elastic block.
[0054] In the second anti-reverse pin 3, multiple elastic anti-reverse plates 32 are distributed at equal angles around the axis of the second insert 31. It can be understood that the number of elastic anti-reverse plates 32 is at least two or more, so as to ensure that the second anti-reverse pin 3 is subjected to more uniform force in the corresponding mounting holes and is more stable after installation.
[0055] Please refer to the following: Figure 3 Furthermore, the elastic anti-reverse plate 32 has an anti-reverse notch 320 at one end near the fixing part 11. Understandably, the anti-reverse notch 320 forms an anti-reverse step 321 at the end of the elastic anti-reverse plate 32. Thus, during the insertion of the second anti-reverse pin 3 into the mounting hole, when the anti-reverse notch 320 reaches the mounting hole, the elastic anti-reverse plate 32 will automatically open to restore its deformation. At this time, the anti-reverse notch 320 will engage in the mounting hole, and the anti-reverse step 321 will abut against the side of the sheet metal facing away from the connecting body 1, thereby preventing the second anti-reverse pin 3 from exiting the mounting hole.
[0056] In this embodiment, the root of the second insertion rod 31 is provided with an abutment block, and the abutment block protrusion 33 is provided on the surface of the fixing part 11. The abutment block is used to contact the surface of the sheet metal to reduce the movement gap between the fixing part 11 and the sheet metal after the fixing clip is installed.
[0057] The maximum extrusion of the second anti-reverse pin 3 is 1mm, and the interference fit allowance with the corresponding mounting hole is greater than or equal to 1.4mm. This ensures that the second anti-reverse pin 3 will not fall out after being inserted into the mounting hole.
[0058] In this embodiment, the length of the first anti-reverse pin 2 is defined as L1, and the length of the second anti-reverse pin 3 is defined as L2, where L1 > L2. Thus, when installing the fixing clip, the first anti-reverse pin 2 can be inserted first into the corresponding mounting hole for initial positioning. Then, the entire fixing clip is rotated and adjusted so that the second anti-reverse pin 3 is aligned with the corresponding mounting hole. Finally, the first anti-reverse pin 2 and the second anti-reverse pin 3 are pressed into the corresponding mounting holes, making installation more convenient.
[0059] In some embodiments, the length of the first anti-reverse pin 2 is defined as L1, and the length of the second anti-reverse pin 3 is defined as L2, where L1 > L2. Thus, when installing the fixing clip, the second anti-reverse pin 3 can be preferentially inserted into the corresponding mounting hole for initial positioning. Then, the entire fixing clip is rotated and adjusted so that the first anti-reverse pin 2 is aligned with the corresponding mounting hole. Finally, the first anti-reverse pin 2 and the second anti-reverse pin 3 are pressed into the corresponding mounting holes, which also improves the ease of installation.
[0060] In other embodiments, the length of the first anti-reverse pin 2 is defined as L1, and the length of the second anti-reverse pin 3 is defined as L2, where L1 = L2. Thus, the first anti-reverse pin 2 and the second anti-reverse pin 3 have the same length. During installation, the first anti-reverse pin 2 and the second anti-reverse pin 3 need to be aligned with their corresponding mounting holes simultaneously, and then pressed into the corresponding mounting holes together. It is understandable that compared to the two unequal length methods described above, the installation requirements are relatively higher, and the material cost is correspondingly increased.
