Description

Technical Field

[0001] This invention relates to a data center cable tray fastener, which is used to fix the data center cable tray onto a C-shaped steel frame. Prior Technology

[0002] With the continuous development of technology, the widespread application of information digitization, cloud computing, and the internet has led to an explosive growth in electronic information. In data centers, to ensure the normal transmission of information, especially during natural disasters such as earthquakes, and to guarantee the uninterrupted operation of communication lines, the fiber optic cable tray (hereinafter referred to as cable tray) system used in data centers must be earthquake-resistant. To achieve this earthquake resistance, the cable tray is installed on a plane composed of multiple C-shaped steel frames, and has a fastening structure on the cable tray. A fastener secures the cable tray to the C-shaped steel frame. This prevents the internal optical fibers from being pulled or detached due to shaking.

[0003] Commonly used cable trays generally come in two styles, differing in their fastening mechanisms. One style features hook-like structures on both sides of the bottom of the cable tray, while the other has multiple hook-like structures on the bottom surface. Because the two styles use different hook-like structures, at least two different types of fasteners are required to secure the cable trays to the C-shaped steel frame. Therefore, consumers must choose the appropriate fasteners based on the type of cable tray they purchase.

[0004] The non-standard fasteners may require considerable caution in the procurement of cable trays or fasteners. For example, if the purchased cable trays and fasteners are of different styles, there will be a waste of costs. Summary of the Invention

[0005] In view of the above problems, the data center cabling duct fastener system of the present invention is designed to fasten two different styles of double-headed fasteners respectively, so as to serve as a universal fastener.

[0006] The present invention relates to a data center cable tray fastener, which is used to fix a first cable tray or a second cable tray to a C-shaped steel frame, and includes a double-headed fastener and a clamping assembly. The double-headed fastener is disposed on the opening of the C-shaped steel frame and has a body, a first fastening end, a second fastening end, and a clamping hole. The first fastening end and the second fastening end respectively form two sides of the body. The first fastening end is used to fasten the first hook of the first cable tray, and the second fastening end is used to fasten the second hook of the second cable tray. The clamping hole is formed on the body. The clamping assembly has a locking fastener and a clamping member. The locking fastener has a threaded section, and the clamping member has a locking hole and at least one clamping end. The clamping member is disposed inside the C-shaped steel frame. The locking fastener passes through the opening between the clamping hole and the two stops of the C-shaped steel frame and is screwed into the locking hole by the threaded section.

[0021] Please refer to Figures 1 and 2. Figure 1 is an exploded perspective view of the data center cable tray fastener 10 of the present invention, and Figure 2 is a plan view of the data center cable tray fastener 10 of the present invention. As shown in the figures, the data center cable tray fastener 10 includes a double-headed fixing member 20 and a clamping assembly 30.

[0022] The double-headed fastener 20 is integrally formed and has a body 21, a first fastening end 22, a second fastening end 23, two first covering ends 24, two second covering ends 25, and a clamping hole 26. The body 21 is a rectangular plate. The first fastening end 22 is formed on one side of the body 21. The end of the first fastening end 22 is hook-shaped, with the opening of the hook facing downward. More specifically, the first fastening end 22 has a hook groove 221, with the opening of the hook groove 221 facing downward. The second fastening end 23 is formed on the side of the body 21 relative to the first fastening end 22. The end of the second fastening end 23 is hook-shaped, with the opening of the hook facing the body 21. More specifically, the second fastening end 23 has a first segment 231, a second segment 232, and a third segment 233. The first segment 231 extends laterally and outward from the side of the body 21. The second segment 232 extends longitudinally and upward from the outer end of the first segment 231. The third segment 233 extends laterally and towards the body 21 from the upper end of the second segment 232. Two first covering ends 24 are formed on the lower side of the body 21 adjacent to the first fastening end 22 or the second fastening end 23, respectively. Two second covering ends 25 are formed on the lower side of the body 21 relative to each of the first covering ends 24, respectively. The clamping hole 26 is formed at the center or near the center of the body 21.

[0023] The clamping assembly 30 includes a locking member 31, a clamping member 32, a washer 33, and a retaining ring 34. The locking member 31 has a head end 311, a threaded section 312, and a recess 313. The head end 311 and the recess 313 are located at their respective ends. The threaded section 312 is located between the head end 311 and the recess 313. The washer 33 is positioned between the head end 311 and the body 21. The clamping member 32 has a locking hole 321 and two clamping ends 322. The locking member 31 passes sequentially through the washer 33 and the clamping hole 26 from the end closest to the recess 313, and the threaded section 312 engages with the locking hole 321, allowing the locking member 31 to engage with the double-headed fixing member 20 and be locked onto the clamping member 32. The retaining ring 34 is positioned within the recess 313.

[0024] The first engaging end 22 and the second engaging end 23 are used to engage with two different types of cable trays. One of the cable trays is the first cable tray 40, as shown in Figure 3, which is a plan view of the data center cable tray fastener 10 of the present invention used to fix the first cable tray 40. As shown in the figure, the first cable tray 40 is a long groove with a U-shaped cross-section. The U-shape has a bottom surface 401 and two side surfaces 402. The two side surfaces 402 are respectively formed vertically on both sides of the bottom surface 401. Thus, a space 403 is formed between the bottom surface 401 and the two side surfaces 402, which can accommodate cables (not shown). Two first hooks 404 are formed at the bottom of the two side surfaces 402. The first hooks 404 fit with the first engaging end 22. Thus, the hooks 221 of the two double-headed fasteners 20 can be engaged with the two first hooks 404. Next, please refer to Figure 4, which is a plan view of the data center cable tray fastener 10 of the present invention used to fix the first cable tray 40 from another perspective. It is then fixed to the C-shaped steel frame 50 by the clamping component 30. The C-shaped steel frame 50 has an upward-facing opening 51, and two stops 52 on both sides of the opening 51. Please refer to Figure 5, which is a cross-sectional view of the clamping component 30 of the data center cable tray fastener 10 of the present invention being fixed to the C-shaped steel frame 50. The locking fastener 31 passes through the opening 51 from one end near the recess 313. Please refer to Figure 6, which is a cross-sectional view of the clamping component 30 of the data center cable tray fastener 10 of the present invention being fixed to the C-shaped steel frame 50. When the threaded section 312 and the locking hole 321 are tightened, the clamping member 32 is forced towards the double-headed fixing member 20. The second stop 52 is located between the clamping end 322 and the double-headed fixing member 20, thus increasing the friction between the second stop 52 and the clamping end 322, and also increasing the friction between the second stop 52 and the double-headed fixing member 20, further realizing the fixing of the double-headed fixing member 20 to the C-shaped steel frame 50 through the clamping assembly 30. In addition, the first covering end 24 and the second covering end 25 can respectively cover the outside of the second stop 52. Since the hook grooves 221 of the two double-headed fixing members 20 engage with the two first hooks 404, the first wiring groove 40 that engages with the two double-headed fixing members 20 can also be fixed to the C-shaped steel frame 50.

[0025] In addition, another type of cable tray is the second cable tray 60, as shown in Figure 7. Figure 7 is a three-dimensional schematic diagram of the data center cable tray fastener 10 of the present invention used to fix the second cable tray 60. As shown in the figure, the second cable tray 60 is a long channel with a U-shaped cross-section. The U-shape has a bottom surface 601 and two side surfaces 602. The two side surfaces 602 are respectively formed vertically on both sides of the bottom surface 601. Thus, a space 603 is formed between the bottom surface 601 and the two side surfaces 602, which can accommodate cables (not shown in the figure). The second cable tray 60 differs from the first cable tray 40 in that at least two second hooks 604 are formed on the bottom surface 601. The second hooks 604 match the second fastening ends 23. Thus, the second section 232 and the third section 233 of the two double-headed fasteners 20 can be fastened to the two second hooks 604. Next, it is fixed to the C-shaped steel frame 50 by means of the clamping component 30. The fixing method of the clamping component 30 and the second cable tray 60 is the same as that of the first cable tray 40, so it will not be described again. Since the second section 232 and the third section 233 of the two double-headed fasteners 20 are fastened to the two second hooks 604, the second cable tray 60, which is fastened to the two double-headed fasteners 20, can also be fixed to the C-shaped steel frame 50.

[0026] In summary, the data center cable tray fastener provided by this invention has a first engaging end 22 for engaging the first hook portion 404 of the first cable tray 40, and a second engaging end 23 for engaging the second hook portion 604 of the second cable tray 60. Therefore, the double-headed fastener 20 can be used with both the first and second cable tray styles 40 and 60. In purchasing or using this fastener, there is no need to specifically select a fastener corresponding to either the first or second cable tray 60, and costs will not be wasted due to purchasing the wrong style.
