Description

Technical Field

[0001] This utility model belongs to the field of power distribution cabinet technology, specifically relating to the cable outlet structure of a drawer cabinet. Background Technology

[0002] In power distribution systems, switchboards, as part of low-voltage distribution equipment, are widely used in power distribution in industrial, commercial, and civil buildings. The outgoing wiring structure of a switchboard typically involves complex copper busbar wiring, which is used to connect the circuit breaker to the power supply and load.

[0003] In traditional designs, the positions of the primary input and output terminals are fixed and not aligned with the circuit breaker interface height. This necessitates additional bending and cutting of the copper busbars to accommodate different height differences, thereby increasing the consumption of copper busbar materials and the complexity of processing. Utility Model Content

[0004] The present invention aims to provide a cable exit structure for drawer cabinets, which can reduce the consumption of copper busbars in drawer cabinets and reduce processing costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The drawer cabinet cable outlet structure includes a drawer cabinet body, a circuit breaker is installed inside the drawer cabinet body, and the rear panel of the drawer cabinet body is provided with a number of primary input terminals and a number of primary output terminals; the circuit breaker is provided with a number of input interfaces and a number of output interfaces, and each input interface of the circuit breaker is located on the same horizontal plane as the corresponding primary input terminal; each output interface of the circuit breaker is located on the same horizontal plane as the corresponding primary output terminal.

[0007] Furthermore, the primary incoming terminals include phase A incoming terminals, phase B incoming terminals, and phase C incoming terminals; the primary outgoing terminals include phase A outgoing terminals, phase B outgoing terminals, and phase C outgoing terminals; the circuit breaker has three incoming interfaces, corresponding to phase A incoming terminals, phase B incoming terminals, and phase C incoming terminals respectively; the circuit breaker has three outgoing interfaces, corresponding to phase A outgoing terminals, phase B outgoing terminals, and phase C outgoing terminals respectively.

[0008] Furthermore, the rear panel of the drawer cabinet body is provided with mounting ports for installing a primary inlet terminal and a primary outlet terminal.

[0009] Furthermore, the rear panel of the drawer cabinet body is provided with vertical grooves and openings corresponding to the positions of each primary inlet and primary outlet. A sliding plate is provided in the groove, and the mounting port is provided on the sliding plate. Several locking screw holes are provided on the rear panel, and locking screws are provided on the sliding plate.

[0010] Furthermore, a secondary cable outlet is also provided on the rear panel of the drawer cabinet body.

[0011] Furthermore, the primary input terminal is a socket; the primary output terminal is a plug.

[0012] Technical principles and beneficial effects of this technical solution:

[0013] 1. Setting the primary input and output terminals to be on the same horizontal plane as all input and output interfaces of the circuit breaker ensures that the height of each phase interface is the same. This reduces the bending of copper busbar cables, the required length of copper busbars, and the processing load. Since a switch cabinet has many drawer cabinets, this adjustment can greatly reduce copper busbar consumption and processing costs.

[0014] 2. The design of the sliding groove and slide plate allows for adjustment of the height of each primary input and output terminal according to the size and model of the circuit breaker, ensuring that the height matches the height of each interface of the circuit breaker. It can also be adjusted to a traditional linear arrangement in special circumstances to meet compatibility requirements, offering strong versatility. Attached Figure Description
