Description

Technical Field

[0001] This utility model belongs to the technical field of wire harness accessories, and more specifically, it relates to a wire harness limiting bracket. Background Technology

[0002] In the assembly of automotive electrical systems, the fixing and limiting of wiring harnesses are crucial for ensuring the safe and stable operation of the circuit. In existing technologies, wiring harnesses are typically installed in the vehicle body or engine compartment using fixed brackets to achieve neat routing and prevent vibration-induced detachment. However, due to differences in the placement of wiring harnesses between different vehicle models or even different configurations of the same model, and because space constraints or structural interference often make precise alignment of the wiring harnesses difficult during assembly, traditional wiring harness brackets are mostly rigid connections with fixed structures and non-adjustable limiting positions. This necessitates forcibly bending the wiring harness to accommodate the limiting points during installation, which not only increases assembly difficulty but also easily causes wear on the wiring harness sheath or loosening of the interfaces. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a wire harness limiting bracket, which solves the problem that existing wire harness brackets are mostly rigid connections with fixed structures, and their limiting positions are not adjustable. This results in the need to forcibly bend the wire harness to adapt to the limiting point during installation, which not only increases the assembly difficulty but also easily causes wear on the wire harness sheath or loosening of the interface.

[0004] The technical solution adopted in this utility model is as follows:

[0006] The mounting plate is provided with mounting holes;

[0007] The adjustment component is mounted on the mounting plate, and the driving end of the adjustment component is connected to the mounting base. The wire harness limiting component is detachably connected to the mounting base. The adjustment component can drive the mounting base to move vertically back and forth and can drive the mounting base to rotate.

[0008] Furthermore, the adjustment assembly includes a slide cylinder, a slide column, a first screw, and a rotating block;

[0009] The slide cylinder is vertically fixedly installed on the upper surface of the mounting plate. The inner cavity of the slide cylinder is a hollow structure with an open upper end. The slide column is vertically slidably sleeved inside the slide cylinder and can rotate within the inner cavity of the slide cylinder. A first threaded hole is provided on the front side wall of the slide cylinder. The rear end of the first threaded hole communicates with the inner cavity of the slide cylinder. The first screw is threadedly connected to the first threaded hole. The rear end of the first screw can abut against the outer side wall of the slide column to limit the position of the slide column inside the slide cylinder. The front end of the first screw is fixedly connected to the rotating block.

[0010] The top of the sliding column is fixedly connected to the bottom of the mounting base.

[0011] Furthermore, it also includes a positioning component, which includes a mounting bracket, a slide bar, a connecting block, a first magnet block, a pull block, a rotating rod, a positioning block, and a support block;

[0012] The mounting bracket is fixedly connected to the outer wall of the slide cylinder and is located on the right side of the first screw. The front side wall of the mounting bracket is provided with a mounting groove, and the left side of the mounting groove is open.

[0015] Furthermore, the wire harness limiting assembly includes a wire harness block, a wire harness groove, and a snap-fit ​​block;

[0016] A snap-fit ​​groove is provided on the front side wall of the mounting base, and a second magnet block is embedded in the front inner side wall of the snap-fit ​​groove;

[0017] The shape of the snap-fit ​​block is adapted to the shape of the snap-fit ​​groove, the snap-fit ​​block can snap into the snap-fit ​​groove, the snap-fit ​​block is a magnetic block structure, and the rear sidewall of the snap-fit ​​block can abut against the front sidewall of the second magnet block and be attracted by the second magnet block.

[0018] The front sidewall of the snap-fit ​​block is fixedly connected to the rear sidewall of the cable tie block. The top of the cable tie block has a vertical cable tie groove that runs through the cable tie block and is used to pass through the cable tie.

[0019] Furthermore, the wire harness limiting assembly also includes a second screw and a handle;

[0035] Example 1:

[0036] As attached Figure 1 To be continued Figure 4 As shown:

[0037] This utility model provides a wire harness limiting bracket, including: a mounting plate 1, an adjustment component 2, and a wire harness limiting component 4;

[0038] The mounting plate 1 is provided with mounting holes 11;

[0039] The adjustment component 2 is mounted on the mounting plate 1. The driving end of the adjustment component 2 is connected to the mounting base 5. The wire harness limiting component 4 is detachably connected to the mounting base 5. The adjustment component 2 can drive the mounting base 5 to move vertically back and forth and can drive the mounting base 5 to rotate.

[0040] In this embodiment, the mounting plate 1 is a sheet metal plate. An insert groove communicating with the mounting hole 11 is provided at the upper end of the mounting hole 11. The insert groove can cover the edge of the hexagon socket bolt, preventing the bolt from protruding too high. The inside of the car is equipped with a sheet metal part for installation, which has threaded holes. When installing this bracket, first, the mounting plate 1 is abutted against the sheet metal part, aligning the mounting hole 11 with the threaded hole. Then, the hexagon socket bolt is passed through the insert groove and the mounting hole 11 in sequence, and threadedly connected to the threaded hole on the sheet metal part, thus fixing the mounting plate 1 to the sheet metal part.

[0041] As a preferred embodiment, the adjustment assembly 2 includes a slide cylinder 21, a slide column 22, a first screw 23, and a rotating block 24;

[0042] The slide cylinder 21 is vertically fixedly installed on the upper surface of the mounting plate 1. The inner cavity of the slide cylinder 21 is a hollow structure with an open upper end. The slide column 22 is vertically slidably sleeved inside the slide cylinder 21 and can rotate within the inner cavity of the slide cylinder 21. A first threaded hole 25 is provided on the front side wall of the slide cylinder 21. The rear end of the first threaded hole 25 communicates with the inner cavity of the slide cylinder 21. The first screw 23 is threadedly connected to the first threaded hole 25. The rear end of the first screw 23 can abut against the outer side wall of the slide column 22 to limit the position of the slide column 22 within the slide cylinder 21. The front end of the first screw 23 is fixedly connected to the rotating block 24. The top of the slide column 22 is fixedly connected to the bottom of the mounting base 5.

[0043] In this embodiment, the sliding column 22 is vertically slidably sleeved inside the sliding cylinder 21. The vertical height of the mounting base 5 can be changed by pulling the sliding column 22. After adjustment, the first screw 23 is tightened, and its rear end abuts against the side wall of the sliding column 22, locking the height through friction. The sliding column 22 can rotate 360° inside the sliding cylinder 21, driving the mounting base 5 and the wire harness limiting component 4 to adjust the angle to adapt to the wire harness routing requirements. The structure is simple and the adjustment is convenient. The height and angle can be adjusted in two dimensions simply by pulling and rotating the sliding column 22. The rigid contact and locking between the first screw 23 and the sliding column 22 provides strong vibration resistance.

[0044] As a preferred embodiment, the system also includes a positioning component 3, which includes a mounting bracket 31, a sliding rod 32, a connecting block 33, a first magnet block 34, a pull block 35, a rotating rod 36, a positioning block 37, and a support block 38.

[0045] The mounting bracket 31 is fixedly connected to the outer wall of the slide cylinder 21 and is located to the right of the first screw 23. The front side wall of the mounting bracket 31 is provided with a mounting groove 39, and the left side of the mounting groove 39 is open.

[0046] The slide rod 32 is vertically fixedly connected to the mounting groove 39. The right side of the connecting block 33 is vertically slidably sleeved on the slide rod 32. The left side wall of the connecting block 33 is fixedly connected to the first magnet block 34. The pull block 35 is fixedly connected to the front side wall of the connecting block 33. The rotating rod 36 is rotatably connected to the pull block 35 and is vertically arranged. The upper end of the rotating rod 36 is fixedly connected to the positioning block 37. The support block 38 is fixedly connected to the front side wall of the mounting frame 31. The bottom of the positioning block 37 can abut against the top of the support block 38.

[0047] The rotating block 24 is a rectangular block structure and a magnetic block structure. The first magnet block 34 can abut against the rotating block 24 and attract the rotating block 24.

[0048] In this embodiment, the upper and lower ends of the slide rod 32 are fixedly connected to the upper and lower inner walls of the mounting groove 39, respectively; the lower part of the rotating rod 36 is rotatably sleeved in the pull block 35; the rotating block 24 is made of ferrite magnetic material, and the first magnet block 34 is made of neodymium iron boron strong magnet; when the first screw 23 is tightened, the connecting block 33 slides down along the slide rod 32, so that the first magnet block 34 and the magnetic rotating block 24 are attached and attracted, and the rotation of the rotating block 24 is further restricted by magnetic force to prevent the first screw 23 from loosening due to vibration; the pull block 35 is pulled upward to drive the first magnet block 34 to disengage from the rotating block 24, so that the rotating block 24 can be rotated to adjust the first screw 23, and the rotating rod 36 is rotated so that the bottom of the positioning block 37 abuts against the top of the support block 38, which can temporarily limit the vertical position of the connecting block 33 and the first magnet block 34, making it easier to operate the adjusting screw.

[0049] As a preferred embodiment, the wire harness limiting component 4 includes a wire harness block 41, a wire harness groove 42, and a snap-fit ​​block 43;

[0050] The mounting base 5 has a snap-fit ​​groove 51 on its front side wall, and a second magnet block 52 is embedded in the front inner side wall of the snap-fit ​​groove 51.

[0051] The shape of the snap-fit ​​block 43 is adapted to the shape of the snap-fit ​​groove 51. The snap-fit ​​block 43 can snap into the snap-fit ​​groove 51. The snap-fit ​​block 43 is a magnetic block structure. The rear sidewall of the snap-fit ​​block 43 can abut against the front sidewall of the second magnet block 52 and be attracted by the second magnet block 52.

[0052] The front sidewall of the snap-fit ​​block 43 is fixedly connected to the rear sidewall of the cable tie block 41. The top of the cable tie block 41 is provided with a vertical cable tie groove 42 that passes through the cable tie block 41. The cable tie groove 42 is used to pass through the cable tie.

[0053] In this embodiment, the snap-fit ​​block 43 is made of ferrite magnetic material, and the second magnet block 52 is made of neodymium iron boron strong magnet. The snap-fit ​​block 43 snaps into the snap-fit ​​groove 51 of the mounting base 5. At the same time, it is initially fixed by the attraction force between the second magnet block 52 and the magnetic snap-fit ​​block 43. Then, the second screw 44 is tightened to make it threadedly connected to the second threaded hole 46 of the snap-fit ​​block 43, so as to achieve double fixation.

[0054] As a preferred embodiment, the wire harness limiting assembly 4 further includes a second screw 44 and a handle 45;

[0055] The second screw 44 is threaded onto the right side wall of the mounting base 5 and extends along the left and right direction of the mounting base 5. The right end of the second screw 44 extends out of the mounting base 5 and is fixedly connected to the handle 45. The right side wall of the snap-fit ​​block 43 is provided with a second threaded hole 46 corresponding to the second screw 44. The left end of the second screw 44 can extend into the snap-fit ​​groove 51 and be threadedly connected to the second threaded hole 46 of the snap-fit ​​block 43.

[0056] In this embodiment, rotating the handle 45 drives the second screw 44 to rotate, so that its left end extends into the snap-fit ​​groove 51 and engages with the second threaded hole 46 of the snap-fit ​​block 43. The snap-fit ​​block 43 is firmly fixed in the snap-fit ​​groove 51 by the pre-tightening force of the threaded connection. The threaded connection has self-locking properties, which can effectively resist axial vibration and prevent the snap-fit ​​block 43 from loosening.

[0057] As a preferred embodiment, the upper and lower sides of the cable tray 42 opposite to the side wall of the mounting base 5 are provided with rounded corners.

[0058] In this embodiment, the cable tie is passed through the cable ties groove 42, and after bundling the wire harness, the excess cable tie is cut off. The rounded corner design of the cable ties groove 42 prevents the cable tie from rubbing against the edge of the wire harness block 41 and breaking.

[0059] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art.
