Description

Technical Field

[0001] This utility model relates to the field of data center boxes, and in particular to a cable tray assembly and a data center box. Background Technology

[0002] In the field of data center infrastructure, cable trays are a key component for cable routing, and their structural design directly affects cabling efficiency, equipment maintenance, and space utilization.

[0003] In existing technologies, traditional cable trays are typically U-shaped and mostly open at the top or side to accommodate and secure cables within the enclosure. However, through practical application, the inventors of this patent have discovered certain drawbacks in these methods. For instance, when installing with the opening facing upwards, considering the equipment placement and space layout within the data center enclosure, it is usually necessary to use top-mounted suspension rods to secure the cable trays, conduits, and other wiring components. The suspension rod method, due to limitations in rod length and size, occupies a significant amount of space on the upper level of the data center enclosure and also presents issues such as height interference with other equipment, making it very inconvenient. If a side-opening method is used, the cable tray is usually placed at the edge of the enclosure's side wall, requiring sufficient space between the cable tray and the enclosure; otherwise, manual securing is impossible. Therefore, a cable tray assembly and data center enclosure structure are needed to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a cable tray assembly and a data center box, so that operators can quickly lay and fix the cable trays, improve the space utilization rate inside the data center box, and make the overall structural space layout inside the box more compact.

[0005] To solve the above-mentioned technical problems, this utility model provides a wire trough assembly, including a wire trough body with an opening, a cover plate, and at least one set of connecting structures;

[0006] The cover plate is detachably connected to the main body of the cable tray, used to block the opening of the main body of the cable tray, and forms a wiring channel for cable routing with the main body of the cable tray;

[0007] One set of the connection structure includes two connectors, which are respectively disposed on opposite outer sides of the wiring channel. One end of each connector is detachably hung on the outer wall of the cable tray body, and the other end abuts against the outer surface of the cover plate, so that the cover plate and the cable tray body remain relatively fixed.

[0008] Furthermore, the connector includes an L-shaped bent part and a support screw;

[0009] The inner side of one end of the L-shaped bending piece has a hook protrusion for detachable connection with the outer wall of the main body of the wire groove;

[0010] The other end of the L-shaped bent piece extends to the bottom of the cover plate and is provided with a threaded hole;

[0011] One end of the support screw is threaded through the threaded hole and can abut against the lower surface of the cover plate.

[0012] Furthermore, the connector includes a first connecting portion and a second connecting portion;

[0013] The inner side of the first connecting part has a hook protrusion for detachable connection with the outer wall of the wire trough body;

[0014] The second connecting part is rotatably mounted on the bottom end of the first connecting part, and forms at least an L-shaped structure with the first connecting part;

[0015] When the first connecting part is connected to the main body of the wire groove, the upper surface of the second connecting part is just flush with the lower surface of the cover plate.

[0016] Furthermore, the outer wall of the main body of the wire trough has multiple slots;

[0017] One end of the connector is selectively and detachably attached to one of the slots.

[0018] Furthermore, the length direction of the slot is parallel to the height direction of the main body of the groove.

[0019] Furthermore, the main body of the trough has a bent portion for forming a clearance area.

[0020] Furthermore, the connection structure is provided in multiple sets, and the connectors of each of the multiple sets of connection structures are symmetrically arranged on opposite sides of the wiring channel.

[0021] On the other hand, the present invention also proposes a data center box, including a box body, a longitudinal support, and a cable tray assembly as described in any of the above embodiments;

[0022] The longitudinal support is fixedly installed on the top wall of the inner cavity of the box;

[0023] The main body of the cable tray is fixedly connected to the longitudinal support, and the opening of the main body of the cable tray faces the side away from the longitudinal support.

[0024] Furthermore, multiple longitudinal supports are provided and are spaced apart on the side of the top wall of the inner cavity of the box.

[0025] Furthermore, it also includes horizontal supports;

[0026] The horizontal support is installed on the top wall of the inner cavity of the box and is used to suspend objects.

[0027] Compared with the prior art, the present invention has at least the following beneficial effects:

[0028] A connecting structure is added to fix the main body of the cable tray to the cover plate to form a wiring channel. The connecting structure provides a reliable and stable connection. Compared with the prior art, the cover plate is not simply used to cover the main body of the cable tray to protect the cable. The existence of the connecting structure in this utility model provides an operable space for the cover plate to provide support for the cable. For example, the main body of the cable is fixed with the opening facing downwards, and the cover plate receives the cable and is fixed to the main body of the cable through the connecting structure. In other words, this utility model, by setting an open cable tray body and a cover plate detachably connected to the cable tray body, and forming a wiring channel between the cover plate and the cable tray body, and by setting at least one set of connection structures including two connectors, with one end of the connector detachably hung on the outer wall of the cable tray body and the other end abutting against the lower surface of the cover plate, allows for a stable connection between the cover plate and the cable tray body after wiring is completed, ensuring the cover plate's support and protection of the cables. This facilitates quick cable arrangement and fixing by operators, making it easy to fix the cable tray body and enabling convenient cable wiring. When applied in energy storage boxes, data center boxes, or even modular buildings, it can improve the wiring efficiency, reliability, and space utilization of cables within the box.

[0029] Furthermore, since the cover plate is detachably connected to the main body of the cable tray under the action of the connector, and the connector is a hanging type design, it is also convenient for operators to maintain or repair the cables without tools. That is, by controlling the separation of the connector from the cover plate, the internal cables can be quickly exposed, which facilitates manual adjustment of cable position or other operations, and is conducive to rapid maintenance or repair.

[0030] Furthermore, by installing the cable tray assembly in conjunction with the longitudinal bracket on the top wall of the data center enclosure, with the opening facing away from the longitudinal bracket, the cabling channel is fixed and the cables are supported from below via the cover plate and connectors. Therefore, compared with the side-opening cable tray structure in the prior art, it can effectively save the large space required for cable fixing between the cable tray structure and the side wall of the enclosure. Moreover, compared with the top-opening cable tray structure in the prior art, which uses a hanging rod installation method, the cover plate and connectors of this device require less space during application and are simpler to install. Therefore, it can effectively reduce the space required during installation and achieve a more compact overall structural space layout. Attached Figure Description

[0039] The cable tray assembly and data center box structure of this utility model will be described in more detail below with reference to the schematic diagrams, which illustrate preferred embodiments of this utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving the advantageous effects of this utility model. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit this utility model.

[0040] Furthermore, based on the teachings of this specification, those skilled in the art can form new technical solutions through cross-combination of different implementation methods without creating technical contradictions. Such variations should all be considered to fall within the protection scope of this patent.

[0041] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0042] Example 1

[0043] like Figures 1 to 4As shown in the figure, this utility model embodiment proposes a wire trough assembly, including a wire trough body 1 with an opening, a cover plate 2, and at least one set of connecting structures.

[0044] The cover plate 2 is detachably connected to the cable tray body 1, used to block the opening of the cable tray body 1, and together with the cable tray body 1 to form a wiring channel for cable routing. That is, the wiring channel formed by the cover plate 2 and the opening of the cable tray body 1 completes the cable routing control, support, and containment protection.

[0045] One of the connection structures includes two connectors 3, which are respectively disposed on opposite sides of the wiring channel.

[0046] Specifically, one end of the connector 3 is detachably hung on the outer wall of the cable tray body 1, and the other end abuts against the outer surface of the cover plate 2, so that the cover plate 2 and the cable tray body 1 remain relatively fixed. That is, the connector 3 is used to connect the cover plate 2 and the cable tray body 1 together, ensuring that the two will not detach under the action of gravity alone, thereby improving the support stability of the cables located in the wiring channel.

[0047] The following explanation uses the application of this device in a data center enclosure as an example:

[0048] Firstly, there are currently two main types of data center containers: one is a single data center container, which can be understood as a shipping container filled with data center equipment and components; the other is a modular building assembled from multiple shipping containers, forming a cluster of data center containers. For this type of data center container, there may be no side walls between adjacent containers, and multiple containers are assembled to form a large, interconnected space.

[0049] For a single data center box or a cluster of data center boxes, in order to make high space utilization within the box, if the cables are laid at the bottom of the box, they will occupy a lot of bottom space, which is not conducive to the placement of other equipment. Therefore, most cables are suspended from the top of the box using a screw rod suspension method. The cable tray opening faces upward, and the side opening is used to install and fix the cable to the top wall. Sufficient space needs to be reserved on both the top and side walls for manual operation and fixing.

[0050] In this embodiment, by setting up a cable tray body 1 with an opening and a cover plate 2 that is detachably connected to the bottom of the cable tray body 1, and by forming a wiring channel between the cover plate 2 and the cable tray body 1, and by setting up at least one set of connection structures including two connectors 3, and setting the connectors 3 to be detachably hung on the outer wall of the cable tray body 1 at one end and abutting against the lower surface of the cover plate 2 at the other end, after the wiring is completed, the cover plate 2 and the cable tray body 1 can be stably connected by the connectors 3 to ensure the support and protection of the cables, so as to facilitate the operator to quickly arrange and fix the cables, and improve the wiring efficiency and reliability of the cables in the data center box structure. In other words, by adding a connecting structure, the main body 1 of the cable tray and the cover plate 2 are fixed together to form a wiring channel. The connecting structure provides a reliable and stable connection. Compared with the prior art, the cover plate 2 is not simply used to cover the main body 1 of the cable tray to protect the cable. The existence of the connecting structure in this utility model provides an operational space for the cover plate 2 to provide support for the cable. For example, the main body 1 of the cable tray can be fixed upside down with the opening facing downwards, and the cover plate 2 can receive the cable and be fixed to the main body 1 of the cable tray through the connecting structure.

[0051] Furthermore, since the cover plate 2 is detachably connected to the main body 1 of the cable tray under the action of the connector 3, and the connector 3 is a hanging type design, it is also convenient for operators to maintain or repair the cables without tools. That is, by controlling the separation of the connector 3 from the cover plate 2, the internal cables can be quickly exposed, which facilitates manual adjustment of the cable position or other operations, and is conducive to rapid maintenance or repair.

[0052] like Figure 3 and Figure 4 As shown, in other embodiments, a specific connector 3 is also proposed to facilitate the operator to quickly connect the cover plate 2 to the cable tray body 1.

[0053] Specifically, the connector 3 includes an L-shaped bent part 31 and a support screw 32.

[0054] The L-shaped bending member 31 has a hook protrusion 33 on the inner side of one end for detachable connection with the outer wall of the main body 1 of the wire groove. The other end of the L-shaped bending member 31 extends to the bottom of the cover plate 2 and is provided with a threaded hole.

[0055] Furthermore, one end of the support screw 32 is threaded through the threaded hole and can abut against the lower surface of the cover plate 2. That is, when the cover plate 2 is installed on the cable tray body 1, the operator only needs to hang the hook protrusion 33 on the outer wall of the cable tray body 1, and then rotate the support screw 32 to move the support screw 32 relative to the L-shaped bending piece 31 in the height direction to abut against the cover plate 2, so that the cover plate 2 and the cable tray body 1 can be connected as a whole, ensuring that the cable is stably placed in the wiring channel, achieving the purpose of convenient operation. When fixing the cable tray body 1 and the cover plate 2, it is not necessary to leave too much space for manual operation. When the cable tray body 1 is used in the box, it is fixed by using the hook protrusion 33. If the cable tray body 1 is set in the top side area of ​​the box 4, it is not necessary to leave too much space for manual operation between it and the side wall of the box. It is enough to insert the hook protrusion 33 into the gap and hang it on the cable tray body 1. Moreover, the cover plate 2 is fixed by the lower surface fixed bearing, so it is not necessary to leave space for manual operation. The combination of the hook protrusion 33 and the support screw 32 can further utilize the weight of the cover plate 2 or even the cable directly laid on the cover plate 2 to ensure that the hook protrusion 33 and the main body 1 of the cable trough are tightly fastened, and the entire main body 1 of the cable trough is firmly fixed.

[0056] It should be noted that the outer wall of the main body 1 of the cable tray has a plurality of slots 11, and one end of the connector 3 is selectively and detachably connected to one of the slots 11, that is, the hook protrusion 33 is detachably connected to the slot 11.

[0057] The connection structure is provided in multiple sets, and the connectors 3 of each of the multiple sets of connection structures are symmetrically arranged on the opposite outer side of the wiring channel to improve the stability of the cover plate 2.

[0058] It should also be noted that the slot 11 is preferably a heat dissipation hole of the main body 1 of the existing groove. That is, in this embodiment, the slot 11 is not only used as a heat dissipation hole, but also as a fulcrum for connecting the hook protrusion 33.

[0059] To facilitate the quick attachment of the hook protrusion 33 to the slot 11, the shape of the slot 11 is further defined. Specifically, the length of the slot 11 is parallel to the height of the main body 1 of the trough, meaning the slot 11 is a vertically elongated strip. This allows operators to quickly attach the hook protrusion 33 vertically from top to bottom into the slot 11, ensuring it abuts against the bottom wall of the slot 11 to form a stable support structure, effectively supporting the subsequent cover plate 2. This design also provides operational space for disassembling the cover plate 2 during maintenance and repair. By pushing the cover plate 2 upwards, the hook protrusion 33 can be disengaged from the slot 11, facilitating the removal of the connector 3.

[0060] Furthermore, it should be noted that the shape of the hook protrusion 33 can be set as an L-shaped structure, a C-shaped structure, or other structures that can stably abut against the bottom wall of the slot 11 and can be separated from the slot 11. It only serves as an intermediate component for connecting or separating the L-shaped bending part 31 from the main body 1 of the wire groove, so its shape is not limited in too much here. It is worth mentioning that the structure and shape of the connector 3 are limited in this embodiment. In actual application, the load-bearing strength and deformation resistance of the connector 3 can also be considered, and some positions of the connector 3 in this embodiment can be structurally reinforced. This will not be elaborated here, but the deformation form and structural reinforcement of this type of connector 3 are all within the protection scope of this utility model.

[0061] In other embodiments, the shape of the cable tray body 1 is further defined to ensure that it does not interfere with other components when installed inside the data center enclosure, thus achieving reasonable clearance. Specifically, the cable tray body 1 has a bent portion to form a clearance area 7 to avoid other suspended structures, such as fire water pipes, located at the top of the data center enclosure.

[0062] Example 2

[0063] like Figure 5 and Figure 6 As shown, the difference between this embodiment and embodiment one is that another type of connector 3 is proposed, which can more conveniently connect the cover plate 2 and the main body 1 of the wire trough.

[0064] Specifically, the connector 3 includes a first connecting part 34 and a second connecting part 35.

[0065] The first connecting part 34 has a hook protrusion 33 on its inner side, which is used to detachably connect to the outer wall of the wire groove body 1.

[0066] The second connecting part 35 is rotatably mounted on the bottom end of the first connecting part 34, and forms at least an L-shaped structure with the first connecting part 34.

[0067] It should be noted that when the first connecting part 34 is connected to the main body 1 of the wire groove, the upper surface of the second connecting part 35 is just flush with the lower surface of the cover plate 2.

[0068] In this embodiment, when the cover plate 2 is installed on the main body 1 of the groove, the operator can install the hook protrusion 33 on the groove hole 11 and rotate the second connecting part 35. Since the first connecting part 34 is limited by the hook protrusion 33 and the groove hole 11, the second connecting part 35 will rotate relative to the first connecting part 34. In this state, the upper surface of the second connecting part 35 is just flush with the lower surface of the cover plate 2. Therefore, when the upper surface of the second connecting part 35 rotates to fit the lower surface of the cover plate 2, it can directly play a supporting role. Therefore, compared with the method of supporting the connector 3 by rotating the support screw 32 in the first embodiment, the time required for the installation and support of the cover plate 2 can be effectively shortened, and the operation is more convenient.

[0069] It should be noted that in this embodiment, the second connecting part 35 and the first connecting part 34 can be connected by a T-shaped support connecting column as a connecting component, so that the two can rotate relative to each other while also supporting each other, that is, the two will not separate, thereby improving the stability of the cover plate 2.

[0070] It should also be noted that the T-shaped support connecting column should have a certain resistance to deformation in order to prevent the second connecting part 35 and the first connecting part 34 from being unable to rotate relative to each other due to deformation during the load-bearing process.

[0071] Example 3

[0072] like Figure 7 As shown, this embodiment proposes a data center box based on embodiment one, including a box body 4, a longitudinal support 5, and the cable tray assembly described in embodiment one.

[0073] The longitudinal bracket 5 is fixedly installed on the top wall of the inner cavity of the housing 4, serving as a support point for the cable tray assembly for installation.

[0074] Specifically, the main body 1 of the cable tray is fixedly connected to the longitudinal support 5, and the opening of the main body 1 of the cable tray faces away from the longitudinal support 5, that is, the opening faces downward, so that the support and cable fixing can be completed from below through the cover plate 2 and the connector 3. Therefore, compared with the side-opening cable tray structure in the prior art, it can effectively save the large space required for cable fixing between the cable tray structure and the side wall of the box 4. Moreover, compared with the top-opening cable tray structure in the prior art, which uses the hanging rod installation method, the cover plate 2 and connector 3 of this device require less space during application and are easier to install. Therefore, it can effectively reduce the space required during installation and achieve a more compact overall structural space layout.

[0075] It should be noted that a gap is reserved between the main body 1 of the cable tray and the inner wall of the box 4. The gap is reserved so that the connector 3 can be connected to the slot 11 on the outer wall of the main body 1 of the cable tray through the gap, ensuring that there is no interference.

[0076] To facilitate the explanation of the differences between the cable tray structure applied to data center enclosures and the existing cable tray structure installation, this paper also proposes the installation method of the cable tray body 1 inside the enclosure 4 and the cable arrangement method, which specifically includes the following steps:

[0077] Fix the bottom of the main body 1 of the cable tray to the longitudinal support 5 so that the opening faces downward;

[0078] The cables are arranged in the inner cavity of the main body 1 of the cable tray, and the two ends of the cables passing through the main body 1 of the cable tray are pre-supported.

[0079] The control cover 2 engages with the main body 1 of the wire trough along the direction of the opening, and surrounds the inner cavity of the main body 1 of the wire trough to form a wiring channel;

[0080] Then, hang the hook protrusion 33 in connector 3 on the slots 11 on both sides of the main body of the trough;

[0081] Finally, adjust the support screw 32 to feed it in the direction close to the cover plate 2, thereby completing the support locking and completing the assembly of the trough structure.

[0082] Through the above steps, the installation process does not occupy a large amount of space on the top of the enclosure 4, allowing the main body 1 of the cable tray to fit snugly against the top wall, side walls, and other edges and corners of the enclosure 4's interior. Therefore, compared to the existing technology where the main body 1 of the cable tray faces upwards and is fixed by suspension rods, this method effectively avoids interference with other equipment in the vertical direction. Furthermore, compared to the existing technology where the main body 1 of the cable tray has a side opening, this method eliminates the need for a large margin between the main body 1 of the cable tray and the edge of the enclosure 4's side wall, thus reducing the space required during installation and resulting in a more compact overall structural layout.

[0083] In this embodiment, multiple longitudinal supports 5 are provided and are spaced apart on the side of the top wall of the inner cavity of the housing 4 to provide multiple connection points for the installation of the cable tray body 1.

[0084] In addition, the data center box also includes a horizontal support 6, which is installed on the top wall of the inner cavity of the box 4 for suspending objects (such as fire water pipes, indicated by circles in the figure).

[0085] Correspondingly, the clearance area 7 formed on the main body of the cable tray 1 provides a large operating space for other equipment or devices that need to be suspended in the data center box, thus avoiding problems such as interference in the placement of devices or equipment as much as possible.

[0086] This device, with its bottom-opening cable tray body 1, cover plate 2, and connector 3, enables cables to be quickly laid out in the data center box, facilitating operators to quickly arrange and fix the cables, and effectively improving the cabling efficiency and reliability within the data center box structure.

[0087] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
