Description

Technical Field

[0001] This invention relates to the field of electrical engineering, and more specifically to a cable harness clamp for use in electrical engineering. Background Technology

[0002] A wire is made of one or more mutually insulated conductors and an outer insulating protective layer, used to transmit electricity or information from one place to another.

[0003] When fixing multiple cables, a cable bundle structure is often used to bring them together. Most existing cable bundle devices use clamps or wire clips for fixing. Although they can do the job well, they still have some shortcomings.

[0004] When fixing cables using traditional devices, multiple cables are often bundled together and then clamped together. However, during the clamping process, the cables in the middle section can only be clamped and fixed by the friction between the outer sheaths of adjacent cables, which often results in some loosening, causing problems with the clamping effect and making it impossible to clamp effectively. At the same time, the cables are bundled together during the clamping process, making it difficult to distinguish them during maintenance.

[0005] Therefore, a cable management device is needed that can effectively clamp cables and keep them neatly separated. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a cable harness clamp for electrical engineering.

[0007] This invention is achieved through the following technical solution:

[0008] A cable harness clamp for electrical engineering includes a fixing frame, which is U-shaped. Two sets of first through slots are symmetrically arranged on the fixing frame, with two slots in each set, and the two slots in each set are opposite each other.

Each third dovetail groove 26 is equipped with a second spring 28. The top end of each second spring 28 is fixedly connected to the bottom end of the corresponding third dovetail block 27, and the bottom end of each second spring 28 is fixedly connected to the bottom surface of the corresponding third dovetail groove 26. Each third dovetail block 27 is fixedly connected to a square sleeve 29 on its side wall. Each square sleeve 29 is slidably connected to a square telescopic rod 30. A center block 31 is fixedly connected between two corresponding square telescopic rods 30. An arc-shaped plate 32 is fixedly connected to the top end of each center block 31, and a center rod 33 is fixedly connected to the bottom end of each center block 31. Each clamping plate 14 is fixedly connected to the top end of multiple U-shaped fixing blocks 34. Each U-shaped fixing block 34 is located at two corresponding adjustment points. Between plates 18, side plates 42 are fixedly connected to both sides of the top of each U-shaped fixing block 34, and rubber pads 35 are fixedly connected to the top of each U-shaped fixing block 34. The bottom end of the rubber pads 35 is fitted against the top of the two side plates 42. Positioning plates 36 are fixedly connected to the side walls of each adjusting plate 18, and multiple locking grooves 38 are provided at the top of each positioning plate 36. Movable grooves 37 are provided on both sides of each U-shaped fixing block 34, and one end of each positioning plate 36 extends into the corresponding movable groove 37 and is slidably connected thereto.

A locking block 39 is rotatably connected to the bottom end of each third locking screw 40, and each locking block 39 extends into the corresponding locking groove 38 and is slidably connected thereto.

[0023] The top end of the locking block 39 is fixedly embedded with a bearing, and the bottom end of the third locking screw 40 extends into the inner ring wall of the corresponding bearing and is fixedly connected to it.

[0024] The top of the side plate 42 is arc-shaped, and the locking strap 16 is made of steel strip with insulating rubber wrapped around its outer wall.

[0025] The top of the lifting plate 9 is fixedly embedded with a bearing, and the bottom end of the second locking screw 8 extends into the inner ring wall of the corresponding bearing and is fixedly connected to it.

[0026] Bearings are fixedly embedded in the side wall of the movable plate 6, and one end of each first locking screw 5 extends into the inner ring wall of the corresponding bearing and is fixedly connected to it.

[0027] Working principle: When using the device, place it in the work area and then secure the cable. Before securing the cable, prepare sufficient clamping plates 14. Refer to the attached document for further instructions. Figure 6The cables are pre-clamped sequentially between two corresponding L-shaped clamps 17. Then, another clamping plate 14 is installed, equipped with guide rods 45 and guide holes 46, ensuring that the corresponding L-shaped clamps 17 can accurately extend between the two adjusting plates 18. Next, the cables are pre-clamped within the multiple sets of L-shaped clamps 17 at the bottom of the newly installed clamping plate 14. After all cables are pre-clamped in this manner, the two first locking screws 5 are rotated, causing the moving plate 6 to move. This allows the moving plate 6 and the fixed plate 3 to lock the ends of the strap 16. After clamping, once the locking strap 16 is clamped, the second locking screw 8 is rotated to increase the distance between the lifting plate 9 and the fixed frame 1, thereby enabling the locking strap 16 to tighten the multiple clamping plates 14. During the clamping process of the clamping plates 14, the rising of the adjusting plate 18 causes the triangular block 19 set on the side wall of the adjusting plate 18 to be stressed and move towards the center, thus ensuring that both sides of each cable are clamped. At the same time, an arc plate 32 is provided to ensure that the top and bottom ends of the cable are clamped, thereby further fixing the cable and completing the tightening work.

[0028] The system includes a first through groove 2, a second through groove 10, and a tightening strap groove 43 to ensure the locking strap 16 can operate normally. It also includes a groove 4 and a protrusion 7 to ensure a more secure clamping of the locking strap 16, increasing the contact area and friction. A positioning rod 11 passes through the lifting plate 9 to prevent it from wobbling. An mounting block 13 is fixed to the lifting plate 9 via a threaded connection block 12 for easy disassembly. A guide rod 45 is provided on the mounting block 13, and a guide hole 46 is provided on the clamping plate 14 to ensure proper installation of multiple clamping plates 14 and prevent misalignment. An insertion rod 20 allows the lowest clamping plate 14 to be properly installed with the mounting bracket 15, ensuring normal operation. The system also includes a first dovetail groove 21, a first dovetail block 22, a first spring 23, and a second dovetail groove 24. The second dovetail block 25, the third dovetail groove 26, the third dovetail block 27, and the second spring 28 are all designed to ensure normal operation and that each component can slide and reset normally. A square sleeve 29, a center rod 33, and a square telescopic rod 30 are provided to ensure that the center block 31 remains aligned with the center position. A U-shaped fixing block 34, a rubber pad 35, and a side plate 42 are provided so that when the center block 31 descends, it enters between the two side plates 42, thus tightly clamping the rubber pad 35 between the center block 31 and the side plate 42. This further clamps the center block 31 and provides a limit, preventing damage to the cable sheath caused by the movement of the center block 31. A positioning plate 36, a movable groove 37, a locking groove 38, a locking block 39, a third locking screw 40, and a horizontal plate 41 are provided to adjust the distance between the two adjusting plates 18, making it suitable for use with cables of various diameters.
