[0044] like Figures 1 to 5 As shown, in some embodiments, a cable tray includes a first side plate 100, a second side plate 200, and a support member 300. The second side plate 200 is disposed opposite to the first side plate 100. One end of the support member 300 is connected to the first side plate 100, and the other end of the support member 300 is connected to the second side plate 200. The support member 300, the first side plate 100, and the second side plate 200 enclose a receiving space for accommodating cables. A protrusion 310 extends from the surface of the support member 300 toward the receiving space. The protrusion 310 has a first end and a second end. The first end is near the connection between the support member 300 and the first side plate 100, and the second end is near the connection between the support member 300 and the second side plate 200. The width of both the first end and the second end is greater than the width of the middle part of the protrusion 310.

[0045] Specifically, the cable tray is a ladder-type cable tray.

[0046] During operation, the protrusion 310 enhances the load-bearing capacity of the support member 300 and strengthens the entire cable tray. This cable tray can enhance the load-bearing capacity of the support member 300 without increasing its thickness or adding additional reinforcing ribs, thus reducing the transportation, manufacturing, and installation costs of the cable tray.

[0047] It should be noted that the protrusion 310 has a first end and a second end. The first end is close to the connection between the support member 300 and the first side plate 100, and the second end is close to the connection between the support member 300 and the second side plate 200. The width of both the first end and the second end is greater than the width in the middle of the protrusion 310, which can strengthen the connection between the support member 300 and the first side plate 100 and the connection between the support member 300 and the second side plate 200.

[0048] Specifically, the first side plate 100 and the second side plate 200 have the same structure. During manufacturing, the same molds, processing techniques, and production processes can be used to manufacture both the first side plate 100 and the second side plate 200. For example, in a stamping process, only one set of molds is needed to produce both the first side plate 100 and the second side plate 200, eliminating the need to design and manufacture separate molds for side plates with different structures, significantly reducing mold development costs and manufacturing cycles. The identical structure of the first side plate 100 and the second side plate 200 gives the cable tray an overall structural symmetry. A symmetrical structure can distribute stress more evenly under load, reducing localized stress concentrations caused by structural asymmetry.

[0049] Specifically, the first side plate 100 and the second side plate 200 are arranged parallel to each other. The cables maintain a relatively stable position between the parallel first side plate 100 and the second side plate 200, reducing the chance of mutual friction and compression between cables due to the irregular structure of the cable tray, thereby reducing the risk of cable wear. In a vibration environment, the parallel first side plate 100 and the second side plate 200 can limit the amplitude of cable sway, preventing excessive swaying from causing wear on cable tray components or other cables.

[0050] Specifically, the first side plate 100 and the second side plate 200 can be rectangular.

[0051] Specifically, the load-bearing component 300 can be a plate-like structure.

[0052] In some embodiments, the protrusion 310 is formed by stamping. That is, the protrusion 310 is formed by stamping the surface of the support member upward.

[0053] Compared to a protrusion formed by a solid structure, this structure reduces the weight of the load-bearing component 300 of the protrusion 310, thereby reducing the overall weight of the cable tray. For example, when installing cable trays in the ceiling of a building, a lighter cable tray can reduce the load on the ceiling structure and improve the safety of the building structure. For temporary wiring cable trays that need to be frequently moved or repositioned, a lighter cable tray is also easier to handle and install, reducing the consumption of manpower and material resources. When subjected to external forces such as vibration, a lighter cable tray generates less inertial force, and the force exerted on the supporting structure and connection parts is correspondingly reduced, which helps to improve the overall stability of the cable tray system.

[0054] This design increases the surface area of ​​the protrusion 310 in contact with the air. The larger the heat dissipation surface area, the faster the heat transfer rate, thus enhancing the heat exchange effect of the carrier 300. In the wiring trays of some high-power equipment, such as the trays in the control cabinets of industrial automation control systems, the cables generate a lot of heat when transmitting large currents. This design, which increases the heat dissipation surface area, helps to improve the overall heat dissipation performance of the tray and prevents faults such as cable insulation aging and short circuits caused by overheating.

[0055] In some embodiments, a plurality of carriers 300 are provided, and the plurality of carriers 300 are spaced apart between the first side plate 100 and the second side plate 200.

[0056] It should be noted that the multiple load-bearing components 300 enhance the connection strength between the first side plate 100 and the second side plate 200. The multiple load-bearing components 300, the first side plate 100, and the second side plate 200 together form a stable frame structure, improving the cable tray's resistance to bending and torsion. When the cable tray is subjected to external loads, the multiple load-bearing components 300 can work together to resist deformation. The spaced-apart load-bearing components 300 facilitate air circulation. The space between the load-bearing components 300 accelerates heat dissipation when the cables inside the cable tray generate heat, improving heat dissipation efficiency.

[0057] Specifically, multiple protrusions 310 are provided. Each protrusion 310 corresponds to one of multiple load-bearing members 300. The multiple protrusions 310 work together to enhance the load-bearing capacity of each load-bearing member 300, thereby improving the strength of the entire cable tray structure.

[0058] In some embodiments, the cable tray includes a first connecting plate 400, which has a first mounting portion 410. The first connecting plate 400 is connected to one end of a first side plate 100, and the other end of the first side plate 100 has a second mounting portion 420. The first mounting portion 410 and the second mounting portion 420 are used to mount external cable trays.

[0059] Specifically, the first mounting part 410 and the second mounting part 420 can be mounting holes. Fasteners are inserted into the mounting holes to achieve connection between multiple cable trays.

[0060] In some embodiments, the cable tray includes a second connecting plate 500, the second connecting plate 500 is provided with a third mounting portion 510, the second connecting plate 500 is connected to one end of a second side plate 200, and the other end of the second side plate 200 is provided with a fourth mounting portion 520. The third mounting portion 510 and the fourth mounting portion 520 are used to mount the cable tray.

[0061] Specifically, the third mounting part 510 and the fourth mounting part 520 can be mounting holes. Fasteners are inserted into the mounting holes to achieve connection between multiple cable trays.

[0062] Specifically, the first connecting plate 400 and the second connecting plate 500 are arranged in parallel. This forms a stable planar frame in the cable tray connection structure, increasing the stability of the connection between multiple cable trays, thereby improving the overall bending and torsional resistance of the cable tray.

[0063] Specifically, the first side plate 100, the second side plate 200, the bearing member 300, the first connecting plate 400, and the second connecting plate 500 can be integrally formed structures.

[0064] In some embodiments, the first connecting plate 400 extends relative to the first side plate 100 in a direction away from the second side plate 200 and extends along the length direction of the first side plate 100; the second connecting plate 500 extends relative to the second side plate 200 in a direction away from the first side plate 100 and extends along the length direction of the second side plate 200. The cable tray forms a flared socket design with the first connecting plate 400 and the second connecting plate 500. The first connecting plate 400 extends relative to the first side plate 100 in a direction away from the second side plate 200, and the second connecting plate 500 extends relative to the second side plate 200 in a direction away from the first side plate 100, such that the distance between the first connecting plate 400 and the second connecting plate 500 is greater than the distance between the first side plate 100 and the second side plate 200, thereby forming a socket that can accommodate the insertion of another cable tray side plate. During connection, the first connecting plate 400 can be tightly inserted into the outer wall of the first side plate 100 of another cable tray, and the second connecting plate 500 is inserted into the outer wall of the second side plate 200 of another cable tray. For example, in actual installation, when the first side plate 100 and the second side plate 200 of one cable tray are inserted into the socket of another cable tray, the edge of the socket fits tightly against the side plates of the first side plate 100 and the second side plate 200. Friction and geometric constraints are used to resist external forces such as tension, pressure, and shear that the cable tray may experience during use, ensuring that the connection does not loosen or separate.

[0065] In other embodiments, the first connecting plate 400 extends relative to the first side plate 100 in a direction close to the second side plate 200 and extends along the length direction of the first side plate 100. The second connecting plate 500 extends relative to the second side plate 200 in a direction close to the first side plate 100 and extends along the length direction of the second side plate 200. The first connecting plate 400 and the second connecting plate 500 form a constricted socket design. The distance between the first connecting plate 400 and the second connecting plate 500 in this structure is less than the distance between the first side plate 100 and the second side plate 200. The constricted socket connection structure enhances the overall stability of the cable tray structure. When multiple cable trays are connected together through this structure, a tightly integrated structure is formed. When subjected to external loads (such as cable weight, vibration, wind load, etc.), the clamping force of the connection effectively prevents relative displacement between multiple cable trays, enhancing the structural stability of the cable tray.

[0066] In some embodiments, the cable tray further includes a third connecting plate 600. One end of the third connecting plate 600 is connected to the bottom of the first connecting plate 400, and the other end is connected to the bottom of the second connecting plate 500. The third connecting plate 600 forms a closed socket structure. The third connecting plate 600 can be flush with the support member 300. When two cable trays are connected, the third connecting plate 600 is inserted into the bottom of the support member 300 of the other cable tray. The third connecting plate 600 eliminates gaps between the support members 300 of adjacent cable trays, enhances the load-bearing capacity of the support member 300, improves the stability of the cable tray when cables are placed on the support member 300, and makes the connection of the cable trays more secure.

[0067] In some embodiments, the cable tray includes a fourth connecting plate 710 and a fifth connecting plate 720. One end of the fourth connecting plate 710 is connected to the bottom of the first connecting plate 400, and one end of the fifth connecting plate 720 is connected to the bottom of the second connecting plate 500. The other ends of the fourth connecting plate 710 and the fifth connecting plate 720 are disposed opposite to each other. There is a gap between the other ends of the fourth connecting plate 710 and the fifth connecting plate 720, such that the fourth connecting plate 710 and the fifth connecting plate 720 form a semi-closed socket structure.

[0068] The fourth connecting plate 710 and the fifth connecting plate 720 enhance the overall stability of the cable tray structure. When multiple cable trays are combined together through this connection, a continuous and stable structure is formed. When subjected to external loads, the synergistic effect between the fourth connecting plate 710 and the fifth connecting plate 720 ensures that the load is evenly distributed throughout the entire cable tray. Compared to a closed structure, the semi-closed structure enhances the heat dissipation performance of the cables. The gap between the fourth connecting plate 710 and the fifth connecting plate 720 allows for air circulation, enabling the heat generated by the cables to dissipate to the outside and preventing heat accumulation within the containment space.

[0069] In some embodiments, the cable tray further includes a cover plate. A first snap-fit ​​groove 810 is provided on the side of the first side plate 100 opposite to the side plate 200, and a second snap-fit ​​groove 820 is provided on the side of the second side plate 200 opposite to the side plate 100. One end of the cover plate is snapped into the first snap-fit ​​groove 810, and the other end of the cover plate is snapped into the second snap-fit ​​groove 820.

[0070] It should be noted that the first snap-fit ​​groove 810 on the first side plate 100 and the second snap-fit ​​groove 820 on the second side plate 200 provide a specific structural foundation for the installation of the cover plate. The cover plate is fixed by snapping its two ends into the first snap-fit ​​groove 810 and the second snap-fit ​​groove 820 respectively. The cover plate can protect the cables inside the cable tray. The cover plate can prevent dust, debris, moisture, etc. from entering the inside of the cable tray, reducing the risk of cable damage caused by external environmental factors.

[0071] Specifically, the first card slot 810 is disposed on the top of the first side plate 100. The second card slot 820 is disposed on the top of the second side plate 200.

[0072] In some embodiments, a first bend 910 is provided on the top of the first side plate 100 extending toward the second side plate 200, and a second bend 920 is provided on the end of the first bend 910 away from the first side plate 100 extending toward the support member 300. A third bend 930 is provided on the top of the second side plate 200 extending toward the first side plate 100, and a fourth bend 940 is provided on the end of the third bend 930 away from the second side plate 200 extending toward the support member 300.

[0073] It should be noted that the first bend 910, the second bend 920, the third bend 930, and the fourth bend 940 can limit the movement of cables within the receiving space. The second bend 920 and the fourth bend 940 extend towards the carrier 300, and during cable laying, they can block and constrain the cables longitudinally, preventing excessive displacement of the cables in the longitudinal direction due to factors such as shaking or external forces, and ensuring that the cables are always kept in a suitable position within the cable tray.

[0074] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
