Description

Technical Field

[0001] This utility model belongs to the field of power distribution cabinet wiring technology, and in particular relates to a cable tray for power distribution cabinet wiring. Background Technology

[0002] A distribution cabinet is an electrical device used to distribute electrical energy, control the on / off state of circuits, and protect electrical equipment. It can distribute electrical energy from a power source (such as a transformer) to various branches according to different needs, ensuring that each electrical device receives appropriate voltage and current. At the same time, the distribution cabinet can protect the circuit from faults such as overload, short circuit, and leakage. When an overload current occurs in the circuit, the circuit breaker in the distribution cabinet will automatically trip to disconnect the circuit and prevent the electrical equipment from being damaged by excessive current.

[0003] Cable trays in power distribution cabinets are devices used to organize and protect wires and cables inside the cabinet. Like a track, they provide an orderly channel for the wires, allowing them to be neatly distributed within the cabinet and preventing them from becoming tangled or messy. Different electrical equipment and wiring layouts within the cabinet require cable trays of varying lengths. During installation, cable trays need to be cut to accommodate different wiring lengths, resulting in waste of some tray material and compromising the overall structure and stability. Therefore, a cable tray for power distribution cabinet wiring is needed, employing a telescopic structure that can be adjusted to a suitable constraint length based on the wiring length, thus avoiding material waste and adapting to wiring requirements of different specifications and lengths.

[0022] In the following description, embodiments of the wiring trough for the distribution cabinet of this utility model will be described with reference to the accompanying drawings.

[0023] Figure 1-4This invention illustrates a wiring trough for a power distribution cabinet according to an embodiment of the present invention. It includes a fixed wiring trough 2 fixedly connected to the inner cavity of the power distribution cabinet 1. Sliding extension wiring troughs 3 are fitted on both sides of the surface of the fixed wiring trough 2. Multiple wire-clamping grooves 6 are provided on the front and rear sides of the top of both the fixed wiring trough 2 and the extension wiring troughs 3. Wires are clamped within the inner cavity of the wire-clamping grooves 6. The wire-clamping grooves 6 limit the branching wires, ensuring they are stably positioned at the connection point and preventing multiple branching wires from branching out simultaneously and causing a messy appearance. Limiting strips 12 are fixedly connected to the front and rear sides of the bottom of the fixed cable trough 2. Arc-shaped limiting grooves 13 adapted to the limiting strips 12 are provided on the front and rear sides of the bottom of the inner cavity of the expansion cable trough 3. Multiple screw mounting holes 14 are provided at the bottom of both the fixed cable trough 2 and the expansion cable trough 3. Wedge-shaped clamps 8 are fixedly connected to the front and rear sides of the top of the expansion cable trough 3. Wedge-shaped sleeves 9 are fixedly connected to the front and rear sides of the inner cavity of the cover plate 7. The wedge-shaped sleeves 9 are fastened to the surface of the wedge-shaped clamps 8. The cover plate 7, wedge-shaped clamps 8 and wedge-shaped clamps 8 are used to fasten the cable trough 2. The use of the set 9 in conjunction with the fixed cable tray 2 and the extended cable tray 3 provides cover and protection for the wires located inside the cavity, preventing them from being exposed and protecting them from external environmental factors. Fixed housings 4 are fixedly connected to both the front and rear ends of the cavity of the distribution cabinet 1. A locking assembly 5 is provided inside the cavity of the fixed housing 4. The locking assembly 5 includes a sliding pin 51 slidably connected to the cavity of the fixed housing 4. A limit slider 10 is fixedly connected to one end of the sliding pin 51 located inside the cavity of the fixed housing 4. Limiting blocks are provided on both sides of the cavity of the fixed housing 4. The sliding block 10 is fitted with a limiting groove 11. The front and rear sides of the fixed wire groove 2 are provided with arc-shaped grooves 53 that are fitted with the sliding pin 51. The surface of the sliding pin 51 is fixedly connected with a limiting block 52. The inner cavity of the arc-shaped groove 53 is provided with multiple limiting slots 54 that are fitted with the limiting block 52. A spring 55 is sleeved on the surface of the sliding pin 51. One end of the spring 55 near the limiting block 52 is welded to the inner wall of the fixed shell 4. The other end of the spring 55 is welded to the sliding pin 51. The top of the fixed wire groove 2 and the extended wire groove 3 are covered with a cover plate 7.

[0024] Working Principle: When using this utility model, the user first fixes the cable tray 2 in the inner cavity of the distribution cabinet 1 by using the screw mounting holes 14 and the screws. Then, according to the wiring length, the user simultaneously presses the two sliding pins 51 on the same side, causing the sliding pins 51 to drive the limiting block 52 to slide and simultaneously exit the inner cavity of the limiting slot 54. At this time, the spring 55 is compressed. Then, the user pulls the extension cable tray 3 away from the fixed cable tray 2, causing the extension cable tray 3 to slide on the surface of the fixed cable tray 2. At the same time, the arc-shaped sliding groove 53 slides on the surface of the sliding pins 51 until the extension cable tray 3 is pulled out to the length that meets the wiring requirements. Then, the user stops pulling the extension cable tray 3. Simultaneously, the sliding pin 51 is released while the cable groove 3 is extended. Under the rebound force of the spring 55, the sliding pin 51 drives the limiting block 52 to engage in the inner cavity of the current limiting slot 54, thus fixing the extension cable groove 3. Then, the extension cable groove 3 is fixed by the cooperation of the screw and the screw mounting hole 14 at the bottom of the inner cavity of the extension cable groove 3. Next, the wires are arranged in the inner cavities of the fixed cable groove 2 and the extension cable groove 3, and the wires that need to be separated are engaged in the inner cavity of the cable groove 6. Finally, the cover plate 7 is pressed on the top of the fixed cable groove 2 and the extension cable groove 3, so that the wedge-shaped clip 8 and the wedge-shaped sleeve 9 can be fastened, thus covering the top of the fixed cable groove 2 and the extension cable groove 3.

[0025] In summary: The wiring troughs used in this power distribution cabinet, through the setting of the locking component 5, allow for adjustment of the lengths used by the expansion trough 3 and the fixed trough 2. Subsequently, the fixed trough 2, the expansion trough 3, and the cover plate 7 work together to organize and store the wires inside the power distribution cabinet 1, thereby achieving the purpose of quickly adjusting the wire length and effectively preventing exposed and messy wires.
