Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinets, and more specifically, to a cable tray connection structure for power distribution control cabinets. Background Technology

[0002] Typically, the input circuits of a distribution cabinet are relatively simple, but the output circuits are extremely complex. A single distribution cabinet can supply power to multiple circuits. As a result, the internal wiring of existing distribution cabinets is often tangled and disorganized, making maintenance and testing extremely cumbersome. Furthermore, the cable management system within the distribution cabinet is prone to scattering due to varying cable lengths, thus negating its intended functions of cable management, aesthetics, and ease of installation. Additionally, inspecting the internal wiring requires disconnecting each circuit individually, which increases maintenance time and costs.

[0003] Application CN 115313163 A relates to a cable tray device for a power distribution cabinet, including a power-off integrated device and a power distribution cabinet. The power-off integrated device is located inside the power distribution cabinet and connected to one side of the cabinet. The power-off integrated device includes a grounding protection component. It also includes a cable tray assembly connected to the grounding protection component. The cable tray assembly includes a sealed protective box, and the side wall of the sealed protective box is fixedly connected to the side wall of the power distribution cabinet. This invention, by rotating a threaded rod, causes the threaded rod to drive the bridge-shaped conductive post and conductive plug on the insulating slide to cooperate with two sets of conductive hole seats, thereby controlling the overall power supply of the power distribution cabinet to external cables. This facilitates maintenance and repair, solving the problem that existing power distribution cabinets require separate circuit breaking operations for each line during maintenance, which increases maintenance time and costs.

[0004] In the aforementioned disclosed structure, the cable tray is positioned and installed using internal fixing components. However, the lack of a combined mounting rod for positioning the conductive cylinder and cable tray not only hinders separate installation and positioning but also makes it impossible to adjust the position and angle of the cable tray, making it unsuitable for staggered arrangement, prone to mutual interference, and affecting safety during use. Therefore, improvements are needed. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a cable strip connection structure for a power distribution control cabinet. The cabinet is connected to a threaded head and a positioning nut to install a limit plate and a mounting rod. It can be assembled and positioned, and the angle can be adjusted by rotation. The cable strip is connected to a conductive cylinder that is slidably installed, and the conductive plate is connected to the internal contacts. The horizontal position can be adjusted for staggered arrangement to avoid interference between multiple cable strips, which is conducive to wiring control, highly adaptable, convenient and stable.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A cable tray connection structure for a power distribution control cabinet includes a cabinet body. A threaded head is rotatably mounted on one side of the cabinet body. A positioning nut is threaded onto one end of the threaded head, and a limit plate is fixedly connected to the other end of the threaded head. A mounting rod is fixedly connected to the side of the limit plate. An elongated groove is provided on the upper surface of the mounting rod. A conductive plate is fixedly connected inside the elongated groove. A conductive cylinder is slidably connected to the outer surface of the mounting rod.

[0009] Furthermore, the cable tray is slidably connected to the lower side of the mounting rod and slidably installed inside the cabinet.

[0010] Furthermore, both the mounting rod and the limiting plate are made of insulating plastic. By connecting the positioning nut and the limiting plate to the two sides of the cabinet respectively, they can be locked and clamped for positioning to prevent loosening. At the same time, they will not interfere with the rotation and angle adjustment, which is conducive to combined use.

[0011] Furthermore, a circular support head is fixedly connected to one end of the mounting rod, and a support cylinder is sleeved on the outer surface of the circular support head.

[0012] Furthermore, a support rod is slidably mounted on the support cylinder, and a tensioning spring is fixedly connected to one end of the support rod.

[0013] Furthermore, a fixing plate is fixedly connected to one end of the support rod. The fixing plate is fixedly installed on the inner surface of the cabinet by screws. The circular support head and the support cylinder are connected by the mounting rod. Combined with the support rod and the fixing plate, they can be positioned together, thereby providing auxiliary support and reinforcement for the mounting rod, improving structural stability and ease of adjustment, and making it highly adaptable.

[0014] Compared with existing technologies, the advantages of this utility model are: (1) This solution uses the cabinet to connect the threaded head and the positioning nut to install the limit plate and the mounting rod. It can be installed and positioned in combination, and the angle can be adjusted by rotation. The conductive tube is connected to the line bar through the sliding installation. Combined with the internal contact to connect the conductive plate, the horizontal position can be adjusted to make staggered arrangement, avoiding interference between multiple line bars, which is conducive to wiring control, highly adaptable, convenient and stable.

[0015] (2) By connecting the positioning nut and the limiting plate to the two sides of the cabinet respectively, the positioning can be locked and clamped to prevent loosening. At the same time, it will not interfere with the rotation and angle adjustment, which is conducive to combined use.

The mounting rod can be combined and positioned to provide auxiliary support and reinforcement, improve the structural stability and the convenience of adjustment, and has high adaptability.

The head 18 is slidably connected to the upper surface of the conductive plate 16. A wire bar 2 is fixedly connected to one side of the outer surface of the conductive cylinder 17. The surface of the wire bar 2 is provided with a combination hole 21. The outer surface of the conductive cylinder 17 is covered with an insulating layer 22. A positioning screw 23 is threadedly connected to the lower surface of the conductive cylinder 17. The positioning screw 23 is tightened and connected to the lower surface of the mounting rod 14.

The position can be adjusted laterally by sliding, and multiple wire bars 2 can be staggered. The wire bars 2 and the conductive cylinder 17 are eccentrically connected. This allows the angle of the mounting rod 14 to be rotated, and the wire bars 2 can be adjusted to different front and rear spacings, thus achieving bidirectional staggering, avoiding mutual interference and contact, improving safety, facilitating connection and positioning, and making adjustment and use convenient.

[0021] Please see Figure 1 and Figure 5 The positioning nut 12 is located on the outer surface of the cabinet 1, and the limiting plate 13 is tightly connected to the inner surface of the cabinet 1.

By connecting the positioning nut and the limiting plate to the two sides of the cabinet respectively, they can be locked and clamped to prevent loosening. At the same time, they will not interfere with the rotation and angle adjustment, which is conducive to combined use.

[0022] Please see Figure 1 and Figure 2One end of the mounting rod 14 is fixedly connected to a circular support head 24. A support cylinder 27 is sleeved on the outer surface of the circular support head 24. A support rod 26 is slidably mounted on the support cylinder 27. A clamping spring 28 is fixedly connected to one end of the support rod 26. A fixing plate 25 is fixedly connected to one end of the support rod 26. The fixing plate 25 is fixedly installed on the inner surface of the cabinet 1 by screws. The circular support head and the support cylinder are connected by the mounting rod. Combined with the fixing plate, they can be positioned and assembled, thereby providing auxiliary support and reinforcement for the mounting rod, improving structural stability and ease of adjustment, and offering high adaptability. The circular support head 24 is made into a free end, which facilitates the combined installation of the conductive cylinder 17 and avoids interference. After the mounting rod 14 is positioned inside the cabinet 1, the support cylinder 27 can be sleeved on the circular support head 24, and then the fixing plate 25 can be positioned and installed. Combined with the clamping spring 28, it can be clamped and supported, allowing for combined installation and positioning. This facilitates the support and limitation of the free end of the circular support head 24, ensuring stability, and also supports rotation and angle adjustment, offering high adaptability.
