[0003] During the wire harness assembly process, the harness needs to be secured. Specifically, individual wires are laid out on a fixture board according to pre-assembled circuits, and then a combination of processes is used to meet specific electrical requirements. Conventional technology typically uses wood or plywood as the fixture board. Wire clamps are then attached to the board according to the product dimensions indicated on the drawing to secure the harness.

The tooling boards are heavy and the switching process is slow. In addition, one tooling board can only realize the assembly of a single product. After the traditional tooling board is modified in the wiring harness product, the original tooling is basically scrapped, resulting in a huge waste of materials and the inability to reuse resources.

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] Please also refer to Figure 1 and Figure 2 The wire harness fixing structure provided by the present invention will now be described. The wire harness fixing structure comprises a tooling plate 1 and a positioning fixture 2. The tooling plate 1 is provided with a plurality of positioning holes 11 arranged in a grid pattern, and a limiting groove 12 is provided on the hole wall of each positioning hole 11; the positioning fixture 2 comprises a positioning portion 21 and a clamping portion 22; the positioning portion 21 is provided with an elastic clamping member 23, and the positioning portion 21 can be inserted into any of the positioning holes 11, and the elastic clamping member 23 is clamped into the limiting groove 12; the clamping portion 22 is connected to the positioning portion 21, and the clamping portion 22 is used to clamp the wire harness.

[0035] It should be noted that the wiring harness fixing structure must be used in conjunction with a circuit diagram. Multiple mounting holes are provided at specific locations on the circuit diagram, which is then covered on the tooling plate 1. The number of positioning fixtures 2 is the same as the number of mounting holes. The positioning fixtures 2 pass through the mounting holes and are inserted and positioned within the positioning holes 11.

[0036] Multiple mounting holes are used to secure the wiring harness, so the distance between adjacent mounting holes is relatively close, meaning the hole density of the multiple mounting holes is low. The multiple positioning holes 11 are distributed in a grid pattern on the tooling plate 1, meaning the spacing between adjacent positioning holes 11 is very close. This results in a high hole density for the positioning holes 11, allowing them to accommodate mounting holes in different locations.

[0037] The tooling board 1 can adopt a modular structure, which can reduce the size of the tooling board 1 accordingly and reduce the space it occupies; when in use, multiple tooling boards 1 are spliced ​​together to form a size that matches the circuit drawing, and when not in use, each tooling board 1 is stored independently.

[0038] During use, in order to ensure the stability of multiple tooling boards 1 after splicing, a support plate 3 can be added, and each tooling board 1 is fixed on the support plate 3 respectively. In this way, the multiple tooling boards 1 do not need to be connected, but only need to be spliced, which simplifies the splicing process.

[0039] The positioning portion 21 is used to be fixed in the positioning hole 11, and the clamping portion 22 is used to clamp the wiring harness. The clamping portion 22 can be a U-shaped structure, a T-shaped structure, or other structures. This embodiment does not limit the specific structure of the clamping portion 22, as long as it can clamp and fix the wiring harness.

[0040] The elastic clip 23 has elastic freedom to move radially along the positioning hole 11. During insertion of the positioning portion 21 into the positioning hole 11, the elastic clip 23 is squeezed by the hole wall of the positioning hole 11, retracting and storing energy to ensure smooth insertion of the positioning portion 21. After the elastic clip 23 moves into the limiting groove 12, it releases energy and is locked and retained within the limiting groove 12. The elastic clip 23 and the limiting groove 12 engage radially along the positioning hole 11 to limit the displacement of the positioning portion 21, thereby ensuring stable fixation of the wiring harness.

[0041] When the fixed position of the wiring harness needs to be switched, the positioning fixture 2 can be directly pulled out manually. The external force applied manually can overcome the elastic force of the elastic clamping part 23, thereby facilitating the rapid plug-in and pull-out switching of the positioning fixture 2.

[0042] Compared with the prior art, the wiring harness fixing structure provided by the present invention only requires drilling mounting holes at specific positions on the circuit drawing when assembling the wiring harness. The circuit drawing is covered on the tooling plate 1, and then the positioning fixture 2 is inserted into the mounting hole and the positioning hole 11. The elastic clip 23 is engaged with the limiting groove 12, so that the positioning fixture 2 is plugged in and fixed stably, thereby ensuring that the wiring harness is stably fixed.

[0043] Since multiple positioning holes 11 are opened on the tooling plate 1 and the multiple positioning holes 11 are distributed in a grid shape, the hole density of the positioning holes 11 is high and can correspond to each mounting hole, complex and dense node harness wiring can be realized to meet high-precision harness wiring requirements.

[0044] In addition, the positioning fixture 2 is plugged into the positioning hole 11. When different circuit drawings are replaced, the positioning fixture 2 can be quickly plugged in and switched to fit different circuit directions, thereby realizing the reuse of the tooling plate 1 and meeting various types of wiring harness production needs.

[0045] Furthermore, the tooling plate 1 can adopt a modular structure, which is small in size, occupies little space, and is easy to maintain.

[0046] In some embodiments, the above-mentioned limiting groove 12 and elastic clamping member 23 can be used as follows: Figure 2 and Figure 5 The structure shown, see Figure 2 and Figure 5 There are at least two limiting grooves 12 , which are spaced apart along the circumference of the positioning hole 11 ; there are at least two groups of elastic clips 23 , and each group of elastic clips 23 is correspondingly clipped into one limiting groove 12 .

[0047] Since the elastic clip 23 and the limiting groove 12 are radially engaged with each other along the positioning hole 11, more than two groups of matching relationships between the elastic clip 23 and the positioning hole 11 are set, and the positioning portion 21 can be limited in at least two directions to prevent the positioning portion 21 from rotating after being inserted into the positioning hole 11.

[0048] To further enhance the anti-rotation function, preferably, refer to Figure 2 The positioning hole 11 is a square hole, and a limiting groove 12 is provided on each side wall of the positioning hole 11.

[0049] Since each side wall of the positioning hole 11 is provided with a limiting groove 12, each side wall is the same, which can simplify the production mold of the tooling plate 1, make the tooling plate 1 simple in structure, low in production and use cost, and convenient for later maintenance.

[0050] In addition, when inserting the positioning portion 21 , there is no need to deliberately adjust the circumferential position of the positioning portion 21 , which can ensure that the elastic clip 23 smoothly enters the limiting groove 12 .

[0051] In order to adapt to the structure of the positioning hole 11, the positioning portion 21 includes a tip 211 and a rectangular parallelepiped portion 212 connected in sequence; the clamping portion 22 is connected to the end of the rectangular parallelepiped portion 212, such as Figure 5 As shown. The tip 211, the cuboid portion 212, and the clamping portion 22 are sequentially connected along the axial direction. The tip 211 is used to guide the insertion into the positioning hole 11. The outer diameter of the cuboid portion 212 is slightly smaller than the inner diameter of the positioning hole 11 to ensure smooth insertion and removal of the cuboid portion 212.

[0052] In some embodiments, the tooling plate 1 can be used as follows Figure 2 and Figure 3 The structure shown, see Figure 2 and Figure 3 The tooling plate 1 includes at least two plate bodies 13 stacked in sequence; the positioning holes 11 penetrate the plurality of plate bodies 13 along the plate thickness direction.

[0053] Among them, in each of the two adjacent plate bodies 13, the upper surface of the lower plate body 13 is provided with an upper groove 121 corresponding to each positioning hole 11, and the lower surface of the upper plate body 13 is provided with a lower groove 122 corresponding to each positioning hole 11; the lower groove 122 corresponds to the upper groove 121 one by one up and down, and forms a limit groove 12.

[0054] Specifically, in each of the two adjacent plate bodies 13, for the upper plate body 13, each positioning hole 11 corresponds to a lower groove 122, and for the lower plate body 13, each positioning hole 11 corresponds to an upper groove 121. After the two plate bodies 13 are superimposed, the upper groove 121 and the lower groove 122 are engaged to form a limiting groove 12.

[0055] The upper groove 121 and the lower groove 122 are respectively formed on the surface of the plate body 13. Compared with the method of directly grooving on the hole wall of the positioning hole 11, the limiting groove 12 is formed by splicing the upper groove 121 and the lower groove 122. The forming method of the limiting groove 12 can be simplified, making it easier to process and manufacture, thereby optimizing the overall structure of the tooling plate 1.

[0056] In order to further simplify the forming method of the upper groove 121 and the lower groove 122, please refer to Figure 2 and Figure 4 On the basis of the above embodiment, the upper grooves 121 between two adjacent positioning holes 11 are mutually connected and coaxially arranged; the lower grooves 122 between two adjacent positioning holes 11 are mutually connected and coaxially arranged.

[0057] The upper groove 121 and the lower groove 122 can be understood as follows: two adjacent positioning holes 11 share one upper groove 121, and two adjacent positioning holes 11 share one lower groove 122. This simplifies the mold for manufacturing the plate body 13, enhances the strength of the plate body 13, and avoids stress concentration on the surface of the plate body 13.

[0058] It should be noted that, for a positioning hole 11, an upper groove 121 may be provided between the positioning hole 11 and each adjacent positioning hole 11, or between the positioning hole 11 and one or several adjacent positioning holes 11. This embodiment does not limit the distribution of the upper grooves 121, as long as the upper grooves 121 can connect two adjacent positioning holes 11. The same method applies to the lower grooves 122.

[0059] See also Figure 4 On the basis of the above embodiment, the multiple upper grooves 121 of each plate body 13 are distributed in a rectangular array, and the multiple lower grooves 122 of each plate body 13 are distributed in a rectangular array.

[0060] The multiple upper grooves 121 can be considered as a parallel, parallel arrangement. For each row of upper grooves 121, the central axes coincide, and for each column of upper grooves 121, the central axes coincide. The same applies to the lower grooves 122. This further simplifies the mold for manufacturing the plate body 13, resulting in a simpler structure for the tooling plate 1, lower production and operating costs, and easier maintenance.

[0061] Preferably, for a positioning hole 11, there is an upper groove 121 between the positioning hole 11 and each adjacent positioning hole 11, so that multiple plate bodies 13 can be stacked at will as long as the outer peripheries overlap, thereby simplifying the stacking method of the tooling plates 1.

[0062] In some embodiments, the elastic clip 23 may also be used as follows: Figure 5 The structure shown, see Figure 5 There are at least two groups of elastic clips 23 , and the at least two groups of elastic clips 23 are spaced apart along the axial direction of the positioning portion 21 and staggered along the circumferential direction.

[0063] At least two groups of elastic clips 23 are not in the same axial direction and not in the same radial direction. At least two groups of elastic clips 23 are staggered. On the one hand, they can avoid each other and avoid elastic conflicts; on the other hand, they can also adapt to the multi-layered plate bodies 13 to ensure that the limiting grooves 12 on each plate body 13 can correspond to the elastic clips 23 for engagement.

[0064] Preferably, in this embodiment, there are three plate bodies 13. The three plate bodies 13 can form two layers of limiting grooves 12, and each positioning portion 21 is correspondingly provided with two groups of elastic clamping members 23.

[0065] In some embodiments, the above-mentioned limiting groove 12 and elastic clamping member 23 can be used as follows: Figure 3 and Figure 5 The structure shown, see Figure 3 and Figure 5 The clamping end of the elastic clamping member 23 is a sphere, and the groove wall of the limiting groove 12 is an arc-shaped surface. The spherical surface of the sphere abuts against the arc-shaped surface. On the one hand, the abutment area can be increased, so that there is surface contact between the sphere and the limiting groove 12, thereby ensuring the stability of the elastic abutment; on the other hand, when inserting and removing the positioning part 21 into the positioning hole 11, it can also ensure that the elastic clamping member 23 can smoothly enter and slide out of the limiting groove 12.

[0066] Specifically, the elastic clamping member 23 includes a sphere and an elastic body, wherein the elastic body is located inside the positioning portion 21 , one end of the elastic body is fixed, and the other end is connected to the sphere.

[0067] In addition, the cross section of the upper groove 121 is a lower semicircle, and the cross section of the lower groove 122 is an upper semicircle. When the lower groove 122 and the upper groove 121 are superimposed, the cross section of the limiting groove 12 formed is circular or elliptical.

[0068] Based on the same inventive concept, the present application also provides a wiring harness fixing system, including the above

[0069] Wire harness fixing structure and circuit drawing; the circuit drawing is covered on the wire harness fixing structure; there are multiple mounting holes on the circuit drawing, each mounting hole corresponds to a positioning hole 11, and a positioning fixture 2 is inserted into the mounting hole and the corresponding positioning hole 11.

[0070] The wire harness fixing system provided by the present invention adopts the above-mentioned wire harness fixing structure, which can realize the reuse of the tooling plate 1, reduce the space occupied by the tooling plate 1, and realize the rapid switching of the fixing of wire harnesses of different products to meet the production requirements of various types of wire harnesses.
