[0028] The preferred embodiments of the present disclosure are described below in conjunction with the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present disclosure and are not used to limit the present disclosure. In addition, the embodiments and features in the embodiments of the present disclosure may be combined with each other if no conflict occurs.

[0029] See also Figure 1 as well as Figure 2 This embodiment provides a wire harness fixing buckle for fixing wire harnesses of different cross-sectional areas, including a wire harness fixing portion and a staple portion 200 connected to each other. The wire harness fixing portion includes two adjacent fixing plates 110 and a connecting plate 120 slidably connected to one of the fixing plates 110. The connecting plate 120 and the two fixing plates 110 form a wire harness placement groove. The connecting plate 120 is slid to change the cross-sectional area of ​​the wire harness placement groove, thereby adapting to and fixing wire harnesses of different cross-sectional areas.

[0030] The staple portion 200 is used for wiring harness to be installed on the predetermined position of automobile. The specific structure of the staple portion 200 is not restricted here, and can be arranged according to actual conditions.

[0031] The two fixing plates 110 are adjacent to each other. It can be understood that the distance between the two fixing plates 110 is relatively close. However, it is not limited here whether the two fixing plates 110 are connected to each other.

[0032] One of the two fixing plates 110 forms the bottom wall of the wiring harness placement slot, while the other and the connecting plate 120 form the two side walls of the wiring harness placement slot. Together, the two fixing plates 110 and the connecting plate 120 form the wiring harness placement slot. Because the two fixing plates 110 may not be connected to each other, the wiring harness placement slot may have gaps. However, it is worth noting that the wiring harness placement slot still serves to accommodate and secure the wiring harness.

[0033] The cross-sectional area of ​​the wire harness that can be fixed by the wire harness fixing portion is the same as the cross-sectional area of ​​the wire harness placement groove. Since the connecting plate 120 is slidably connected to a fixing plate 110, that is, the cross-sectional area of ​​the wire harness placement groove changes with the length of the fixing plate 110 serving as the bottom wall, the cross-sectional area of ​​the wire harness that can be fixed by the wire harness fixing portion matches the length of the fixing plate 110 serving as the bottom wall in the wire harness placement groove.

[0034] In this embodiment, two adjacent fixed plates 110 and a connecting plate 120 slidably connected to one of the fixed plates 110 together form a wire harness placement groove, so that the connecting plate 120 slides with one of the fixed plates 110 to change the cross-sectional area of ​​the wire harness placement groove, thereby allowing the wire harness placement groove to fix wire harnesses of different cross-sectional areas.

[0035] The wiring harness fixing buckle in this embodiment can arbitrarily adjust the clamping size within a preset width range to match wiring harnesses of different cross-sectional areas, reducing the number of wiring harness fixing buckles in the entire vehicle, achieving the purpose of material standardization, and reducing the wiring harness fixing cost of the entire vehicle.

[0036] In some embodiments, see Figure 1 as well as Figure 2 The fixing plate 110 includes a first fixing plate 111 and a second fixing plate 112 connected to each other. A first through hole 121 is set on the connecting plate 120. The first fixing plate 111 passes through the first through hole 121. The connecting plate 120 slides on the first fixing plate 111 to change the distance between the first fixing plate 111 and the second fixing plate 112.

[0037] It should be understood that in this embodiment, “the first fixing plate 111 ” and “the second fixing plate 112 ” are used to describe the two fixing plates 110 , which is only used to distinguish the two. The first fixing plate 111 and the second fixing plate 112 are different fixing plates 110 .

[0038] The size of the first through hole 121 provided on the connecting plate 120 may match the size of the first fixing plate 111 , so that the first fixing plate 111 may pass through the first through hole 121 .

[0039] The connecting plate 120 and the second fixing plate 112 respectively form the two side walls of the wiring harness placement groove, while the first fixing plate 111 forms the bottom wall of the wiring harness placement groove. As the connecting plate 120 slides on the first fixing plate 111, the distance between the connecting plate 120 and the second fixing plate 112 changes, causing the cross-sectional area of ​​the wiring harness placement groove to change. At this time, part of the first fixing plate 111 forms the bottom wall of the wiring harness placement groove.

[0040] As an example, a slide structure may be provided in the first through hole 121 , and the connecting plate 120 is slidably connected to the first fixing plate 111 via the slide structure.

[0041] In other embodiments, the second fixing plate 112 can be passed through the first through hole 121 of the connecting plate 120, so that the connecting plate 120 slides on the second fixing plate 112, thereby adjusting the distance between the connecting plate 120 and the first fixing plate 111. In this case, the first fixing plate 111 and the connecting plate 120 respectively form the two side walls of the wiring harness placement groove, and at least a portion of the second fixing plate 112 forms the bottom wall of the wiring harness placement groove.

[0042] In some embodiments, the harness fixing buckle further includes a plurality of cable ties 300 . The second fixing plate 112 and the connecting plate 120 are arranged opposite to each other and both are provided with a plurality of cable tie holes 400 . The cable ties 300 pass through the cable tie holes 400 and are bundled and fixed in the harness placement slot.

[0043] A plurality of means two or more. In this embodiment, there is no specific limitation on the number of the cable ties 300.

[0044] Multiple tie holes 400 can be provided on the sidewalls of the wiring harness placement slot, i.e., on both the second fixing plate 112 and the connecting plate 120. The number of tie holes 400 is not limited. For example, the number of tie holes 400 provided on the second fixing plate 112 and the connecting plate 120 can be the same. Furthermore, the tie holes 400 can be located anywhere on the second fixing plate 112 and the connecting plate 120, and are not specifically limited thereto. For example, the tie holes 400 can be located at opposing positions on the second fixing plate 112 and the connecting plate 120.

[0045] As an example, when the second fixing plate 112 and the connecting plate 120 respectively have two tie holes 400, a tie 300 can pass through one of the tie holes 400 of the second fixing plate 112 and the connecting plate 120, and fix its two ends on the outside of the wiring harness placement groove, and a tie 300 can pass through the other tie hole 400 of the second fixing plate 112 and the connecting plate 120, and fix its two ends on the outside of the wiring harness placement groove, and the two tie ties 300, the second fixing plate 112 and the connecting plate 120 together bundle and fix the wiring harness.

[0046] In some embodiments, see Figure 1 as well as Figure 2 Along the extension direction of the second fixing plate 112 and the connecting plate 120, a first set of tie hole groups 410 and a second set of tie hole groups 420 are arranged opposite to each other at intervals. The tie 300 passes through the first set of tie hole groups 410, then returns and passes through the second set of tie hole groups 420 and is tightened.

[0047] The first tie hole group 410 may include two tie holes 400 spaced apart along the extension direction of the second fixing plate 112. The second tie hole group 420 may include two tie holes 400 spaced apart along the extension direction of the connecting plate 120. The tie holes 400 included in the first tie hole group 410 and the tie holes 400 included in the second tie hole group 420 are arranged opposite each other.

[0048] A cable tie 300 can be inserted through any one of the cable tie holes 400 included in the first cable tie hole group 410 or the cable tie holes 400 included in the second cable tie hole group 420 , and then sequentially passed through the other cable tie holes 400 and fastened.

[0049] In some embodiments, see Figures 4 to 6 The wiring harness also includes a plate-shaped hard wiring harness 500. The second fixing plate 112 and the connecting plate 120 are provided with fixing grooves 600 on one side close to the first fixing plate 111. Both sides of the plate-shaped hard wiring harness 500 are clamped in the fixing grooves 600 and fixed in the wiring harness placement groove.

[0050] The plate-shaped rigid wiring harness 500 can be secured within the wiring harness placement slot via the securing slot 600. It is understood that the securing slot 600 and the tie hole 400 are located at different positions on the second fixing plate 112 and the connecting plate 120, respectively. In this case, while the tie 300 secures the conventional wiring harness through the tie hole 400, the securing slot 600 also secures the plate-shaped rigid wiring harness 500.

[0051] As an example, the plate-shaped rigid wiring harness 500 includes at least one plate-shaped conductor, PCB, FFC, or FPC, or any combination of two or more. "At least one" means one or more, and the number of plate-shaped conductors, PCBs, FFCs, or FPCs included in the plate-shaped rigid wiring harness 500 is not specifically limited.

[0052] A plurality of fixing slots 600 may be provided on the second fixing plate 112 and the connecting plate 120 . The number of the fixing slots 600 may be the same as the number of the plate-shaped conductors, PCBs, FFCs or FPCs included in the plate-shaped rigid wiring harness 500 .

[0053] The connecting plate 120 slides on the first fixing plate 111 to change the cross-sectional area of ​​the harness placement slot, thereby securing planar rigid harnesses 500 of varying widths. The maximum width of the planar rigid harness 500 that can be secured by the harness securing portion is the same as the length of the first fixing plate 111, which serves as the bottom wall of the harness placement slot.

[0054] In some embodiments, see Figure 3 、 Figure 4 as well as Figure 6 The wiring harness fixing buckle also includes a bolt 710. The connecting plate 120 and the second fixing plate 112 are extended on the side opposite to the wiring harness placement groove to form a first extension portion 122 and a second extension portion 112a respectively. A second through hole is provided on one of the first extension portion 122 and the second extension portion 112a, and a threaded hole 720 is provided on the other. The bolt 710 passes through the second through hole and is screwed to the threaded hole 720 to adjust the distance between the connecting plate 120 and the second fixing plate 112.

[0055] In this embodiment, “first extension portion 122 ” and “second extension portion 112 a ” are used to describe the extended areas of the connecting plate 120 and the second fixing plate 112 , respectively, and are only used to distinguish between the two.

[0056] Insert bolt 710 through the second through-hole and thread it into threaded hole 720, securing connecting plate 120 to the first fixing plate 111. After tightening bolt 710, connecting plate 120 cannot slide, ensuring stable securing of the wiring harness. To adjust connecting plate 120 and change the cross-sectional area of ​​the wiring harness placement slot, remove bolt 710 from threaded hole 720.

[0057] In some embodiments, a second through hole is provided on the second extension portion 112a, two fixing columns extend from the first extension portion 122 toward one side of the second extension portion 112a, the free ends of the fixing columns are connected to the beam structure 123, and the threaded hole 720 is provided on the beam structure 123.

[0058] The threaded hole 720 is arranged on the beam structure 123. It can be understood that the first extension portion 122 of the connecting plate 120 is also provided with a third through hole opposite to the threaded hole 720, so that when the distance between the connecting plate 120 and the second fixing plate 112 is less than the length of the bolt 710, the bolt 710 can pass through the third through hole.

[0059] In this embodiment, the provision of the crossbeam structure 123 can make the force on the connecting plate 120 more uniform when the bolt 710 adjusts the connecting plate 120, thereby optimizing the performance of the wiring harness fixing buckle.

[0060] In some embodiments, the staple portion 200 is fixedly connected to the first fixing plate 111 or the second fixing plate 112 .

[0061] When the staple portion 200 is fixedly connected to the first fixing plate 111 , the bottom wall of the wiring harness placement groove is connected to the staple portion 200 ; when the staple portion 200 is fixedly connected to the second fixing plate 112 , a side wall of the wiring harness placement groove is connected to the staple portion 200 .

[0062] As an example, the staple portion 200 may include a staple and an adapter, wherein one end of the adapter is connected to the staple and the other end is fixedly connected to the first fixing plate 111 or the second fixing plate 112. The staple can be matched with the sheet metal hole of the vehicle body so that the wiring harness fixing clip is installed at a predetermined position of the vehicle.

[0063] Although the preferred embodiments of the present disclosure have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concepts. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present disclosure.

[0064] Obviously, those skilled in the art may make various changes and modifications to the embodiments of the present disclosure without departing from the spirit and scope of the embodiments of the present disclosure. Thus, if such changes and modifications of the embodiments of the present disclosure fall within the scope of the claims of the present disclosure and their equivalents, the present disclosure is intended to include such changes and modifications.
