Description

Technical Field

[0001] This utility model relates to the field of cabinet cable management accessories, and in particular to a T-shaped cable clip structure for tool-free cable management in cabinets. Background Technology

[0002] With the increasing demand for cable management in server racks, traditional cable fixing solutions based on plastic cable ties have emerged. These solutions use nylon cable ties with adjustable tension to achieve cable categorization and bundling, and are characterized by low cost and easy operation.

[0003] In this technology, construction workers need to complete three operations within the narrow space at the bottom of the cabinet: first, they use cable ties to bundle together cables of different specifications, such as signal cables and power cables; second, they secure the cables by tightening the ends of the cable ties; and finally, they use a special tool to cut off any excess cable ties and clean up any debris. This work mode has formed a complete cable management standard in small- to medium-scale deployment scenarios.

[0004] However, the above-mentioned traditional cable ties fixing method has the following technical problems:

[0005] Firstly, each operation requires repeating the three steps of threading, tightening, and cutting, which reduces construction efficiency in high-density cabling scenarios in server racks.

[0006] Secondly, the tightening force of cable ties relies entirely on manual experience, which can easily lead to quality problems such as the cable being too tight and damaging it, or too loose and causing it to come loose.

[0007] Third, the plastic debris generated during shearing is difficult to clean completely in a closed cabinet environment, and long-term accumulation may cause heat dissipation problems. Utility Model Content

[0008] In response to the shortcomings of the existing production technology, the applicant provides a T-shaped cable clamp structure for tool-free cable management in cabinets, thereby achieving tool-free positioning and clamping of cables, and allowing for flexible adjustment of the cable fixing position as needed.

[0009] The technical solution adopted in this utility model is as follows:

[0010] A T-shaped cable clip structure for tool-free cable management in server racks, the cable clip including a bracket, pressure plate, adapter plate, rivets and bolts;

[0011] The support includes a base plate and symmetrical side plates perpendicularly disposed at the edge of the base plate, forming a U-shaped opening structure. The base plate is provided with a first through hole, and the opening end of the side plate is provided with symmetrical slots.

[0012] The rivet passes through the first through hole and is fixed to the bracket by riveting, and its flange and boss hold both sides of the base plate.

[0013] The bolt includes a screw and a handle, the screw passing through the third screw hole of the rivet and extending out of the flange side, and the end of the screw having a rivet neck that can be formed into a rivet head;

[0014] The adapter plate is sleeved on the rivet neck through the second through hole, and a floating connection with the bolt is formed by the spin-pressing rivet head;

[0015] The pressure plate is provided with a T-slot and a parallel guide surface. The T-slot is interference-fitted with the side of the adapter plate, and the guide surface is slidably fitted with the inner side of the bracket.

[0016] The rotating handle drives the pressure plate to slide along the inner side of the bracket, thereby adjusting the cable clamping.

[0017] In one embodiment, the bottom of the slot is an arc-shaped bottom edge, and the second end face of the slot opening side is lower than the first end face of the bracket, forming an inverted T-shaped fastening structure.

[0018] In one embodiment, the rivet groove of the rivet is tightened against the inner wall of the first through hole, so that the rivet and the bracket form a non-rotatable integral riveting assembly.

[0019] In one embodiment, the adapter plate and the rivet neck after the rivet head is formed are clearance fit to achieve a floating connection of the adapter plate.

[0020] In one embodiment, the third end face of the pressure plate is provided with a lower arc surface, the radius of curvature of which is adapted to the outer diameter of the cable.

[0021] In one embodiment, the handle is located at the tail of the screw, and the pressure plate is slidable by manual rotation to adjust the clamping force.

[0022] In one embodiment, the sliding direction of the pressure plate is parallel to the bolt axis, and the guide surface of the pressure plate is slidably adapted to the inner side of the bracket.

[0023] In one embodiment, a guide rail is also included, the fourth end face of which is provided with a first groove; the bracket engages with the first groove through a slot, allowing the wiring clamp to slide and adjust along the guide rail.

[0024] In one embodiment, the guide rail is locked to the nut post by a countersunk screw. The countersunk screw passes through the countersunk hole of the guide rail and is screwed into the first screw hole of the nut post, so that the guide rail is clamped between the countersunk screw and the nut post.

[0025] In one embodiment, the nut post includes a first threaded hole and a stud extending through the first threaded hole, the stud being used to fix to a second threaded hole on the rack mounting plate.

[0026] The beneficial effects of this utility model are as follows:

[0027] This utility model has a compact structure. By integrating a handle at the end of the bolt and sliding the pressure plate with the inner side of the bracket, rotating the handle directly drives the pressure plate to move up and down along the guide surface, replacing the traditional three-step operation of "threading-tightening-cutting". This reduces the time for fixing a single cable and improves the efficiency of rack deployment. In addition, the lower arc surface of the pressure plate physically presses the cable, eliminating the need for cutting throughout the process and completely eliminating the risk of heat dissipation caused by the accumulation of plastic debris.

[0028] This utility model also has the following advantages:

[0029] The inverted T-shaped design of the bracket slot (arc bottom edge + recessed second end face) and the groove edge limit of the first groove of the guide rail of this utility model allow the wiring clamp to slide along the fourth end face of the guide rail, realizing flexible adjustment of the cable grouping position.

[0063] Furthermore, the accompanying drawings are not drawn to a 1:1 scale, and the relative dimensions of the components are shown in the drawings only as examples and not necessarily to actual scale.

[0064] like Figures 1-2 The accompanying drawing shows a schematic diagram of the structure of a wiring clip according to an embodiment of the present invention; for ease of description, the drawing only shows the structure related to the embodiment of the present invention.

[0065] This application provides a T-shaped wiring clamp structure, which is assembled by a bracket 20, a pressure plate 30, an adapter plate 40, rivets 50 and bolts 60.

[0066] In some embodiments, the support 20 includes a base plate 21 and symmetrical side plates 23 perpendicularly disposed at the edge of the base plate 21, forming a U-shaped opening structure;

[0067] Furthermore, the substrate 21 has a first through hole 22 at its center; the side plate 23 has symmetrical slots 24 at its open end, the bottom 25 of the slot 24 is designed as an arc bottom edge 26, and the second end face 29 of the slot 24 is lower than the first end face 28 of the bracket 20, forming an inverted T-shaped locking structure; the inner wall of the side plate 23 is an inner side surface 27, which is used to guide the sliding of the pressure plate 30.

[0068] In some embodiments, the rivet 50 passes through the first through hole 22, and its rivet groove 53 is tensioned to the inner wall of the first through hole 22, so that the rivet 50 and the bracket 20 form a non-rotatable integral riveting assembly.

[0069] Furthermore, the flange 54 and boss 52 of the rivet 50 clamp the two sides of the base plate 21 to achieve axial positioning.

[0070] In some embodiments, the bolt 60 includes a screw 61 and a handle 62; the screw 61 passes through the third screw hole 51 of the rivet 50 and extends out of the flange 54 side, and the end of the screw 61 is provided with a rivet neck 63;

[0071] Furthermore, the adapter plate 40 is sleeved on the rivet neck 63 through the second through hole 41. After being spun into the rivet head 64, the adapter plate 40 and the rivet neck 63 are in clearance fit, forming a floating connection of the bolt 60.

[0072] In some embodiments, the pressure plate 30 is provided with a T-slot 31 and a parallel guide surface 34; the T-slot 31 is interference-fitted with the plate side 42 of the adapter plate 40, and the guide surface 34 is slidably fitted with the inner side surface 27 of the bracket 20.

[0073] Furthermore, the third end face 33 of the pressure plate 30 is provided with a lower arc surface 32, the radius of curvature of the arc surface 32 is adapted to the outer diameter of the cable 130, so as to avoid damaging the cable 130.

[0074] The operating principle is as follows:

[0075] Rotating the handle 62 drives the screw 61 to rotate, which in turn moves the adapter plate 40 axially, pushes the pressure plate 30 to slide along the inner side 27, and presses or releases the cable 130 on the arc surface 32.

[0076] In some embodiments, the guide rail 70 is further included. The fourth end face 71 of the guide rail 70 is provided with a first groove 72 and groove edges 73 on both sides of the groove. The first groove 72 is engaged with the slot 24 of the bracket 20.

[0077] Furthermore, the guide rail 70 is provided with a countersunk hole 74 and a bottom surface 75 for the countersunk screw 76 to be inserted.

[0078] Furthermore, the guide rail 70 also includes a nut post 77, which includes a first threaded hole 771 and a stud 772 passing through the first threaded hole 771.

[0079] The installation steps are as follows:

[0080] The stud 772 is screwed into the second screw hole 92 of the mounting plate 90;

[0081] After the countersunk screw 76 passes through the countersunk hole 74, it is screwed into the first threaded hole 771 of the nut post 77, so that the guide rail 70 is clamped between the countersunk screw 76 and the nut post 77.

[0082] In some embodiments, the slot 24 of the bracket 20 engages with the first slot 72 of the guide rail 70, and the slot edge 73 restricts lateral displacement; the push cable clamp 10 can slide along the fourth end face 71 of the guide rail 70 to flexibly adjust the grouping position of the cable 130.

[0083] like Figures 1-2As shown, during the assembly of the wiring clamp 10, the assembly of each component must follow a specific sequence to ensure smooth assembly. First, the rivet 50 is riveted with the flange 54 facing down into the pre-reserved first through hole 22 of the bracket 20, forming a boss 52 and a rivet groove 53. The rivet groove 53 is tightened against the inner wall of the pre-reserved first through hole 22. The boss 52 and the flange 54 clamp the rivet 50 on the upper and lower sides of the pre-reserved first through hole 22, thus making the rivet 50 and the bracket 20 a riveted assembly. Second, the bolt 60 is passed through the third... The screw hole 51 is screwed out from the flange 54 side. At this time, the rivet head 64 is not yet formed, i.e., the rivet neck 63 remains in the state. Then, the adapter plate 40 is installed into the rivet neck 63 of the bolt 60 through the second through hole 41. The rivet head 64 is screwed out at the end of the rivet neck 63 using a special tool. After the rivet head 64 is formed, the rivet neck 63 and the second through hole 41 of the adapter plate 40 are rotatably connected with a gap. At this point, the adapter plate 40 and the bolt 60 become a single assembly. Finally, the T-slot 31 of the pressure plate 30 is inserted into the plate side 42 of the adapter plate 40, and the two are interference-fitted. At the same time as the pressure plate 30 is inserted into the adapter plate 40, its parallel and opposite guide surface 34 is also inserted into the inner surface 27 of the bracket 20, and is slidably fitted with the inner surface 27 of the bracket 20. At this point, the assembly of all parts of the wiring clip 10 is complete. Tightening the handle 62 of the bolt 60 can drive the pressure plate 30 to move up and down along the axis of the bolt 60 on the inner side 27 of the bracket 20.

[0084] like Figures 3-4 As shown, in practical applications, the wiring clip 10 must be used in conjunction with the guide rail 70. The T-shaped wiring clip assembly 80 consists of the wiring clip 10, the guide rail 70, the countersunk screw 76, and the nut post 77. The assembly sequence is as follows: First, insert the wiring clip 10 into the first slot 72 along the fourth end face 71 of the guide rail 70 as indicated by the arrow in the diagram. The fourth end face 71 is the left and right end face of the guide rail 70. Under the limiting and guiding effect of the slot edge 73, each wiring clip 10 can slide and adjust between the fourth end faces 71. After installing the required number of wiring clips 10, according to the positions of the left and right countersunk holes 74 of the guide rail 70, use the countersunk screw 76 to lock the nut post 77 onto the guide rail 70. At this time, the countersunk screw 76 is flush with the bottom surface 75 of the guide rail 70, and the threaded portion passing through the countersunk hole 74 is locked into the first threaded hole 771 of the nut post 77, so that the guide rail 70 is clamped between the countersunk screw 76 and the nut post 77, completing the assembly. The above assembly process and sequence can be reversed according to the needs of cabinet electrical integration.

[0085] like Figures 5-6 The image shows an application example of the T-type cabling clamp assembly 80 in cabinet 120.

[0086] First, the mounting plate 90 of the cabinet 120 has two corresponding second mounting screw holes 92 pre-set near the bottom frame 110. Loosen the two countersunk screws 76 on the T-shaped cable clamp assembly 80, but do not unscrew them to keep them in a floating state. Then tighten the nut posts 77 into the second screw holes 92 respectively, and then tighten the countersunk screws 76 to fix the T-shaped cable clamp assembly 80 on the mounting surface 91 of the mounting plate 90. Second, pass the cables 130 from the second slot 101 of the bottom sealing plate 100 through the cable clamps 10 one by one. Adjust the distance between the cable clamps 10, and turn the handle 62 by hand. The bolt 60 drives the pressure plate 30 to press the cables 130 tightly onto the groove edge 73 of the guide rail 70. The firmness can be felt by the resistance when turning the handle 62. Repeat the above actions to press all the cables 130 in sequence to complete the tool-free cabling work.

[0087] In summary, the handle 62 of this utility model is integrated into the tail of the bolt 60. Rotation directly drives the pressure plate 30 to slide, replacing the traditional "threading-tightening-cutting" process of cable ties, realizing tool-free operation. Moreover, physical clamping without shearing action eliminates the heat dissipation hazards caused by the accumulation of plastic debris. In addition, the adapter plate 40 and the rivet neck 63 are fitted with a clearance to compensate for assembly errors and ensure smooth sliding of the pressure plate 30. The arc bottom edge 26 of the slot 24 and the recessed second end face 29 enhance the locking stability and prevent dislodgement.

[0088] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0089] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
