Description

Technical Field

[0001] This utility model relates to a cable tray, and more particularly to a cable tray for data centers. Background Technology

[0002] Data centers are globally collaborative networks of specific devices used to transmit, accelerate, display, compute, and store data information on network infrastructure. Due to the large number of cables in a data center, multiple cables are usually laid within the cable tray itself.

[0003] For example, Chinese Patent Publication No. CN220234064U discloses a multi-functional adjustable cable tray device for data center computer rooms, including a first cable tray, a second cable tray, and a cable clamping frame. The first cable tray has sliding grooves on both sides of its surface, and spring clips are installed on both sides of the top notch of the first cable tray. The second cable tray has locking blocks vertically connected to both sides of its surface, allowing the first and second cable trays to interlock. Both the first and second cable trays have multiple mounting holes on their surfaces, and the cable clamping frame can be fixed to the surfaces of the first and second cable trays using bolts and mounting holes. This invention, through the cooperation of the first and second cable trays, sliding grooves, spring clips, and locking blocks, not only achieves convenient assembly and disassembly of the first and second cable trays but also enables the second cable tray to slide and extend within the first cable tray, increasing the length of the cable tray and thus achieving convenient and flexible construction of the cable tray.

[0004] Some problems were found when using the existing multi-functional adjustable cable tray device for data center computer rooms. First, there is no dividing mechanism inside the cable tray, and all the cables are piled up inside the cable tray, which will cause the cables to be scattered and tangled together. Since most of the data center cables are used to transmit data, when the cables are tangled together, the interference between the cables will affect the stability and reliability of data transmission. Utility Model Content

[0005] The purpose of this invention is to provide a cable tray for data centers to solve the existing problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a data center cable tray, comprising a cable tray body, the cable tray body being U-shaped with the opening facing downwards, support studs being fixedly connected to the top of the cable tray body near the four corner edges, fixing nuts being threaded onto the support studs, a plurality of cable trays being provided inside the cable tray body, and connecting through holes being opened in the cable trays near the four corner edges, the connecting through holes cooperating with the support studs, and a plurality of snap-fit ​​grooves being opened on the cable trays.

[0007] Preferably, the cable tray body has connecting edges fixed to both the front and rear ends, connecting feet fixed to both sides of the cable tray body, and a pull rod sleeved inside the connecting feet.

[0008] Preferably, a limiting groove is provided under the cable tray, a return spring is fixedly connected in the limiting groove, a limiting pin is fixedly connected to the other end of the return spring, and a shifting handle is fixedly connected below the limiting pin.

[0009] Preferably, the inner walls on both sides of the cable tray body are provided with limiting slots, and the limiting slots cooperate with the limiting pins.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. By placing the cable inside the slot, the cable tray is lifted downwards and snapped into the inside of the cable tray body. The top of the cable will contact the top of the cable tray body, thus squeezing and fixing the cable inside the slot, restricting the cable from moving freely, and preventing the cables from stacking and tangling together, which would cause interference between the cables and affect the stability and reliability of data transmission.

[0012] 2. By using a lifting method to fix the cable tray inside the cable tray body, compared with the traditional method of pulling the cable tray to install it, firstly, it avoids the friction between the cable and the cable tray, thus avoiding damage to the cable insulation; secondly, it eliminates the need for pulling, making it more convenient to lay the cable inside the cable tray.

[0013] 3. When the lifting cable tray is inserted into the cable tray body, the limit pin will be pushed into the limit slot by the return spring, initially securing the cable tray inside the cable tray body. At this time, the operator can free up both hands to rotate the fixing nut onto the support stud, making it convenient for a single operator to install. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a data center cable tray, including a cable tray body 1, the cable tray body 1 is U-shaped with the opening facing downwards, a support stud 2 is fixedly connected to the top of the cable tray body 1 near the four corner edges, a fixing nut 201 is threaded on the support stud 2, a plurality of cable trays 3 are provided inside the cable tray body 1, a connection through hole 301 is opened in the cable tray 3 near the four corner edges, the connection through hole 301 cooperates with the support stud 2, and a plurality of snap-fit ​​grooves 302 are opened on the cable tray 3.

[0022] In this embodiment, the cable tray 3 is equipped with various specifications, and the size of its locking slot 302 varies. The appropriate locking slot 302 size needs to be selected based on the thickness of the cable to be laid. The cable is placed inside the locking slot 302, and the cable tray 3 is lifted downwards to engage with the inside of the cable tray body 1. The support stud 2 passes through the connecting through hole 301, and the cable is secured within the locking slot 302. As the cable tray 3 rises, the top of the cable contacts the top of the inside of the cable tray body 1, thus squeezing and fixing the cable inside the locking slot 302, restricting the cable from moving freely. Multiple cable trays 3 can be installed inside the cable tray body 1. By using the fixing nut 201 to press the bottom of the cable tray 3, the cable tray 3 is fixed inside the cable tray body 1. The layered fixing method can further utilize the internal space of the cable tray body 1 and avoid the cables from stacking and tangling together, which would lead to interference between cables and affect the stability and reliability of data transmission. At the same time, the lower end of the cable tray body 1 is open, and the cable tray 3 is lifted to fix the cable inside the cable tray body 1. Compared with the traditional method of pulling the cable to install it inside the cable tray, firstly, it avoids the friction between the cable and the cable tray, avoiding damage to the cable insulation. Secondly, it does not require pulling, making it more convenient to lay the cable inside the cable tray.

[0023] To achieve the purpose of fixing the cable tray 3 to the cable tray body 1, the device adopts the following technical solution: the front and rear ends of the cable tray body 1 are fixedly connected with connecting edges 101, the two sides of the cable tray body 1 are fixedly connected with connecting feet 102, the connecting feet 102 are fitted with pull rods 103, the cable tray 3 is provided with a limiting groove 4, the limiting groove 4 is fixedly connected with a return spring 401, the other end of the return spring 401 is fixedly connected with a limiting pin 402, the limiting pin 402 is fixedly connected with a shift handle 403, the inner walls of both sides of the cable tray body 1 are provided with limiting slots 104, and the limiting slots 104 and the limiting pins 402 cooperate with each other.

[0024] By passing the connecting foot 102 through the connecting edge 101 and fixing the connecting foot 102 to the top of the data center, the cable tray body 1 can be suspended. The return spring 401 can provide a certain pushing force to the limit pin 402. The limit pin 402, under the pushing force, will insert into the limit slot 104, thus initially locking the cable tray 3 inside the cable tray body 1. The end of the limit pin 402 has a bevel. When the cable tray 3 is moved up into the cable tray body 1, the bevel of the limit pin 402 contacts the cable tray body 1. At this time, the force on the limit pin 402 will... When the force is decomposed, a portion of the force will push the limit pin 402 back into the limit slide groove 4, allowing the cable tray 3 to be smoothly pushed into the cable tray body 1. During the downward movement of the cable tray 3, the force on the limit pin 402 cannot be decomposed, allowing the cable tray 3 to be initially locked inside the cable tray body 1. At this time, the operator can free up both hands to rotate and install the fixing nut 201 inside the support stud 2, and use the fixing nut 201 to stably fix the cable tray 3 inside the cable tray body 1. The shift handle 403 can drive the limit pin 402 to move.

[0025] The working principle and usage process of this utility model are as follows: When in use, the connecting foot 102 is passed through the connecting edge 101 and fixed to the top of the data center. The cable tray body 1 can then be suspended. Select a correspondingly sized locking slot 302 according to the required cable thickness, place the cable inside the locking slot 302, and lift the cable support plate 3 downwards to engage it inside the cable tray body 1. The support stud 2 should then pass through the connecting through hole 301. At this time, the limiting pin 402 will engage inside the limiting slot 104 under the push of the return spring 401. Initially, the cable tray 3 is inserted into the cable tray body 1. At this point, the operator can free up both hands to rotate and install the fixing nut 201 onto the support stud 2. With the fixing nut 201, the cable tray 3 is stably fixed inside the cable tray body 1. It is best to use the same cable tray 3 to fix cables of the same diameter. If there are not enough cables of the same size, cables with small size deviations can be fixed on the same cable tray 3. Try to make full use of the top cable tray 3 before installing the next layer of cable tray 3.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
