Description

Technical Field

[0001] This utility model relates to the field of cabinet accessories and their cable classification and organization technology, and in particular to a cabling support structure at the bottom of the cabinet cavity. Background Technology

[0002] With the development of cabinet accessories and cable classification and organization technologies, modular cable management technology has gradually become a key solution in the field of electrical integration. This technology, through standardized interface design and space optimization layout, realizes the classification and organization of signal lines, power lines and control lines, significantly improving the systematicness and maintainability of cabling inside the cabinet, and thus giving rise to special accessories such as integrated cable transition devices.

[0003] In related technologies, traditional processing methods mainly employ an open wiring structure between the base and the bottom sealing plate, using cable ties or cable trays to secure the cables. Typical characteristics include:

[0004] 1) Use functional zoning as a guide for extensive grouping;

[0005] 2) Relying on human experience to determine cable routing;

[0006] 3) Basic physical isolation is achieved solely through metal partitions.

[0007] The above-described approach meets basic cabling requirements in simple control scenarios; however, this traditional cable handling method has three major drawbacks:

[0008] First, the electromagnetic compatibility design is lacking, and the industry standard that signal lines and power lines must maintain a shielding distance is not strictly followed, making the control signals susceptible to strong electric interference.

[0009] Secondly, the cable identification system is incomplete, and the mixing of cables of various specifications reduces the efficiency of troubleshooting later.

[0010] Finally, due to a lack of scalability, fixed cable trays are difficult to adapt to the wiring changes brought about by equipment iterations. Utility Model Content

[0011] In response to the shortcomings of the existing production technology, the applicant provides a cabling bracket structure at the bottom of the cabinet cavity, which enables the bracket structure itself to physically classify cables of various specifications and quantities during installation, isolate them at equal intervals in space, and facilitate fixing.

[0012] The technical solution adopted in this utility model is as follows:

[0013] A cabling bracket structure at the bottom of a server rack cavity includes a cabling bracket assembly, comprising a bracket, legs, and self-tapping screws;

[0014] The support has a C-shaped cross-section structure, and the base surface and the auxiliary surface are connected by a beveled joint to form a stepped surface structure. The base surface and the auxiliary surface are provided with an array of through grooves and cross-surface grooves along the length direction, and form narrow and wide ribs with alternating widths.

[0015] The bracket has symmetrical notches at both ends, and protrusions are formed at the notches. The protrusions have outer holes and inner holes. The base surface edge has a small folded edge, and the auxiliary surface edge has a large folded edge. The small folded edge and the large folded edge are perpendicular to their respective planes in the same direction.

[0016] The support leg has a cap-shaped cross-section structure, and the width of the support leg is adapted to the notch of the bracket. The top surface, bottom surface and side surface of the support leg are respectively provided with a top hole, a bottom hole and a side hole. The bracket is connected to the side hole or top hole of the support leg by a self-tapping screw.

[0017] As a further improvement to the above technical solution:

[0018] In one embodiment, in the stepped surface structure, the base surface and the auxiliary surface are parallel and not coplanar, and a height difference is formed by the oblique joint surface to improve the rigidity of the support.

[0019] In one embodiment, the through grooves and cross-surface grooves are alternately distributed, the width of the narrow ribs is adapted to the binding of small-diameter cables, and the width of the wide ribs is adapted to the binding of large-diameter cables.

[0020] In one embodiment, the side of the support leg is provided with a plurality of side holes, the spacing of which matches the hole spacing of the outer and inner holes of the bracket, so as to realize the multi-position adjustable installation of the bracket on the support leg.

[0021] In one embodiment, the support leg is connected and fixed to the modular holes of the cabinet bottom frame through bottom holes, or connected and fixed to the preset holes of the mounting plate through bottom holes.

[0022] In one embodiment, the distance between the outer hole and the inner hole of the protrusion at the notch of the bracket is different, to adapt to the installation requirements of the top or side of the support leg.

[0023] In one embodiment, the cable ties pass through the through slot or the cross slot and wrap around the reinforcing bars to secure the cables sequentially at equal intervals; wherein the reinforcing bars are narrow reinforcing bars or wide reinforcing bars.

[0024] In one embodiment, the bottom entry channel of the cable is a combined bottom sealing plate, which is located between the base and the bottom frame, and the bottom entry of the cable is achieved by a structure that can be completely or partially disassembled.

[0025] In one embodiment, the base cover is detachably connected by fasteners, and the detachable cover is configured to allow cables to enter the cabinet cavity from the bottom side of the base.

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

[0027] This utility model features a compact structure and convenient operation. The bracket adopts a C-shaped cross-section, with the base surface and auxiliary surface forming a stepped surface structure through a beveled joint. Combined with the small folded edge of the base surface and the large folded edge of the auxiliary surface for vertical reinforcement, the overall bending strength of the bracket is significantly improved, preventing deformation when the wiring is under load. The base surface and auxiliary surface are alternately opened with through grooves and cross-surface grooves along the length, forming narrow and wide ribs. Small-diameter and large-diameter cables are bound separately by cable ties to achieve physical isolation, reduce the risk of electromagnetic interference, and at the same time, the cables are evenly distributed for easy identification and management.

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

[0029] (1) The support leg of this utility model is designed with a hat-shaped cross section. Multiple sets of side holes and top holes are provided on its side and top surfaces respectively. Combined with the difference in the distance between the outer hole and the inner hole at the bracket notch, it supports the multi-hole adjustment and installation of the bracket on the support leg, which can adapt to different cabinet layout requirements.

[0030] (2) The support legs of this utility model are fixed to the modular holes of the bottom frame through the bottom holes, or connected to the preset holes of the mounting plate through the top holes. With the detachable combination bottom sealing plate and base cover plate, the bottom cable entry channel can be opened without the whole assembly and disassembly, so as to adapt to the needs of equipment iteration or cable addition and subtraction.

[0031] (3) The assembly design of the bracket and legs of this utility model is divided into two pre-assembly modes (parallel to the mounting plate or the bottom frame) to meet the wiring path planning of different cabinet scenarios, while reducing the dependence on the modification of the original cabinet structure and improving versatility.

[0049] 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.

[0050] like Figures 1-2 The accompanying drawing shows a schematic diagram of the structural state of a wiring bracket structure at the bottom of a cabinet cavity 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.

[0051] The cabinet cavity bottom cabling bracket structure of this embodiment includes a cabling bracket assembly 1, including a bracket 2, a support leg 3 and a self-tapping screw 4;

[0052] The support 2 has a C-shaped cross-section structure. The base surface 201 and the auxiliary surface 203 are connected by the oblique joint surface 202 to form a stepped surface structure. The base surface 201 and the auxiliary surface 203 are provided with arrayed through grooves 209 and cross-surface grooves 210 along the length direction, and form narrow ribs 211 and wide ribs 212 with alternating widths.

[0053] The bracket 2 has symmetrical notches 206 at both ends, and protrusions are formed at the notches 206. The protrusions have outer holes 207 and inner holes 208. The base surface 201 has a small folded edge 205 at its edge, and the auxiliary surface 203 has a large folded edge 204 at its edge. The small folded edge 205 and the large folded edge 204 are perpendicular to their respective planes in the same direction.

[0054] The support leg 3 has a cap-shaped cross-section structure. The width of the support leg 3 is adapted to the notch 206 of the bracket 2. The top surface 301, bottom surface 305 and side surface 303 of the support leg 3 are respectively provided with top hole 302, bottom hole 306 and side hole 304. The bracket 2 is connected to the side hole 304 or top hole 302 of the support leg 3 by self-tapping screw 4.

[0055] In some embodiments, in the step surface structure, the base surface 201 and the auxiliary surface 203 are parallel and not coplanar, and a height difference is formed by the oblique joint surface 202 to improve the rigidity of the bracket 2.

[0056] In some embodiments, through slots 209 and cross slots 210 are alternately distributed, the width of narrow ribs 211 is adapted to the binding of small diameter cables 7, and the width of wide ribs 212 is adapted to the binding of large diameter cables 7.

[0057] In some embodiments, the side 303 of the support leg 3 is provided with a plurality of side holes 304, and the arrangement spacing of the side holes 304 matches the hole spacing of the outer hole 207 and the inner hole 208 of the bracket 2, so as to realize the multi-position adjustable installation of the bracket 2 on the support leg 3.

[0058] In some embodiments, the support leg 3 is connected and fixed to the modular hole 601 of the cabinet bottom frame 6 through the bottom hole 306, or connected and fixed to the preset hole 502 of the mounting plate 5 through the bottom hole 306.

[0059] In some embodiments, the distance between the outer hole 207 and the inner hole 208 of the protrusion at the notch 206 of the bracket 2 is different to adapt to the installation requirements of the top surface 301 or the side surface 303 of the support leg 3.

[0060] Please see Figure 3 and Figure 4 As shown, there are two pre-assembly modes of the wiring bracket assembly 1 of this utility model:

[0061] like Figure 3 As shown, when the base surface 201 of the bracket 2 is parallel to the side surface 303 of the support leg 3, it can be assembled with either of the two side surfaces 303. Since each side surface 303 has 3 side holes 304, the bracket 2 has two installation positions on the side of each set of support legs 3, and the difference between the two is one hole distance, which provides an adjustment amount for specific wiring.

[0062] like Figure 4 As shown, when the base surface 201 of the bracket 2 is parallel to the top surface 301 of the support leg 3, the base surface 201 has two sets of mounting holes along its length: outer hole 207 and inner hole 208. Therefore, the support leg 3 can be flexibly selected to be assembled with which set of holes according to the wiring site.

[0063] Please see Figure 5 and Figure 6 The two pre-assemblies of the cabling bracket assembly 1 correspond to two usage scenarios in specific cabinet environments:

[0064] like Figure 5 As shown, the support leg 3 is locked in the modular hole 601 of the base frame 6, and the bracket 2 is locked in the side hole 304 of the support leg 3. At this time, the base surface 201 of the bracket 2 is parallel to the mounting surface 501 of the mounting plate 5. Then, the cable 7 from the base 10 is tied to the narrow rib 211 or wide rib 212 of the bracket 2 in sequence and at equal intervals with cable ties 8. The narrow rib 211 corresponds to the small diameter cable, and the wide rib 212 corresponds to the large diameter cable.

[0065] like Figure 6As shown, the support leg 3 is locked in the preset hole 502 on the mounting surface 501 of the mounting plate 5, and then the bracket 2 is locked in the top hole 302 of the support leg 3. At this time, the base surface 201 of the bracket 2 is still parallel to the mounting surface 501 of the mounting plate 5, which is determined by the bottom cable entry scheme.

[0066] The combined bottom sealing plate 9 is located above the base 10 and below the bottom frame 6. According to the needs of the bottom cable entry scheme, one of the combined bottom sealing plates 9 located in front of and below the mounting surface 501 of the mounting plate 5 is removed to facilitate the passage of the cable 7 from the base 10. Then, as mentioned above, the cable 7 is tied to the narrow rib 211 or wide rib 212 of the bracket 2 in sequence and at equal intervals using cable ties 8.

[0067] Meanwhile, since the cover plate 1001 in the width direction of the base 10 is movable and detachable, and there is one in front and one in the back, according to the needs of on-site electrical installation, the cover plate 1001 can be removed by removing the fastener 1002, so that the cable can enter the cabinet from the side bottom of the base 10.

[0068] If the end customer has reserved a unified cable routing trench, there is no need to remove any parts on the base 10. Only the part of the combined bottom sealing plate 9 located at the lower front of the mounting surface 501 of the mounting plate 5 needs to be removed to smoothly implement the bottom cable entry solution.

[0069] In summary, the present invention has a reasonable structure. The rigidity is enhanced by the stepped surface design of the C-shaped cross-section bracket 2. The base surface and auxiliary surface are provided with alternating through grooves 209 and cross-surface grooves 210 to form wide and narrow ribs to accommodate the binding of cables 7 with different diameters using cable ties 8. The support leg 3 adopts a cap-shaped cross-section and can be flexibly installed in multiple positions with the base frame 6 or mounting plate 5 through the top hole 302, side hole 304 and bottom hole 306. With the detachable combination bottom sealing plate 9 and base cover plate 1001, the bottom cable entry channel is optimized, solving the problems of electromagnetic interference, confusing markings and poor expandability in traditional wiring.

[0070] 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.

[0071] 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.
