Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a wiring structure for a power distribution cabinet. Background Art

[0002] The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), and metering cabinet (box). It is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits; the motor control center is used in places where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load. In order to summarize and arrange the cables in the distribution cabinet, a wiring mechanism is required.

[0003] The common wiring structure for power distribution cabinets is usually composed of a mounting plate and an arc-shaped gusset plate, and a wiring groove is opened at the corresponding position on the front of the mounting plate, and the arc-shaped gusset plate is evenly hinged on both sides of the corresponding wiring groove on the front of the mounting plate. When in use, after inserting the cable from the cable inlet of the power distribution cabinet into the interior, the cable rises through the wiring groove corresponding to the front of the mounting plate, and is connected to the corresponding electrical component equipment, and then the corresponding arc-shaped gusset plate is buckled to limit and fix the cable. This is a common wiring structure and usage method for power distribution cabinets. When the traditional wiring structure for power distribution cabinets limits and fixes the cables inside the power distribution cabinet, it is necessary to first install the power distribution cabinet cables in the wire fixing mechanism, and then use bolts to fix the wire fixing mechanism, so as to limit and fix the cables inside the power distribution cabinet, but this operation method and process are relatively cumbersome, which makes it inconvenient for the staff to quickly disassemble and install the cables inside the power distribution cabinet. Some wiring structures for power distribution cabinets add mutually attractive magnetic structures at the corresponding positions of the mounting plate and the arc-shaped gusset plate, so that the mounting plate and the arc-shaped gusset plate are magnetically connected, which is convenient for cable disassembly and assembly. Although this method is easy to disassemble and use due to the magnetic connection, the connectivity and stability are poor. The magnetic connection is very easy to separate when affected by external factors (such as vibration, etc.), so the cable cannot be fixed in place, resulting in multiple groups of cables being scattered and intertwined inside the power distribution cabinet, and even entangled and pulled with each other, and there is a risk of short circuit. For this reason, a wiring structure for a power distribution cabinet is proposed. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a wiring structure for a power distribution cabinet to solve the above-mentioned technical problems.

The box door can be opened to operate the electrical components and cables of the power distribution cabinet housing.

[0012] Preferably, both sides and the rear end of the wiring board are composed of mounting side panels, and the mounting side panels are designed as a whole in a U-shape, and the centers of both sides of the inner wall of the mounting side panels are provided with T-shaped slots, and the T-shaped slide plates are located at corresponding positions of the inner cavities of the T-shaped slots. The T-shaped slide plates drive the connection structure to move along the T-shaped slots, so that the wire fixing plate is located just above the top of the corresponding wire entry hole, so as to facilitate connection with the corresponding cables.

[0013] Preferably, holes are provided at the front and rear ends of the connection blocks on the front and rear T-shaped slides, and double-ended telescopic screws are provided between the connection blocks on the adjacent T-shaped slides, and the front and rear telescopic ends of the double-ended telescopic screws extend into the corresponding holes of the T-shaped slides. The distance between the adjacent front and rear plates is adjusted by the double-ended telescopic screws, and the double-ended telescopic screws can be separated from the corresponding connection blocks.

[0014] Preferably, a fixing plate is installed on both the front and rear sides of the top of the mounting side plate, and a guide rod is inserted in the center of the front of the fixing plate, a limit plate is installed in the center of the surface of the guide rod, and a compression spring is sleeved on the front end of the surface of the guide rod. The guide rod extends inward through the fixing plate under the action of the limit plate and the compression spring.

[0015] Preferably, the rear ends of the guide rods are rotatably connected to a clamping plate, and the back side of the clamping plate is in contact with the two sides of the front side of the corresponding connecting top plate. The guide rod drives the clamping plate to fix the connecting top plate, which, on the one hand, improves the stability of the connecting top plate; on the other hand, the clamping plate can be rotatably disconnected from the connecting top plate, so that the connecting top plate and the connected structure can be loosened and separated from the T-slot of the mounting side plate, so that the cable fixing plate can be replaced according to the size and number of the fixed cables.
