Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and more specifically, to a power distribution cabinet circuit breaker installation component. Background Technology

[0002] Traditional circuit breaker mounting components in distribution cabinets have a simple structure. After installation, the circuit breaker is covered by a baffle, exposing only the operating part. When the circuit breaker needs maintenance, the baffle must be removed, making maintenance difficult. Moreover, when the circuit breaker is installed on the electrical rail, the gap between the circuit breaker and the rail results in multiple circuit breakers not being arranged neatly.

[0003] Therefore, it is necessary to improve the traditional circuit breaker installation components in distribution cabinets. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a circuit breaker installation component for a power distribution cabinet.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a circuit breaker mounting assembly for a distribution cabinet, comprising a front maintenance terminal mounting plate, an inner door, a terminal fixing bracket, and an electrical guide rail; the four corners of the front maintenance terminal mounting plate are provided with first elongated holes for mounting and engaging with the left and right corner gauges of the distribution cabinet; the front maintenance terminal mounting plate is provided with first square holes along the left and right directions, the inner door is fitted into the first square holes and mounted on the front maintenance terminal mounting plate via hinges, the inner door can be opened forward, and the inner door is provided with a lock body that can lock the inner door to the front maintenance terminal mounting plate; the electrical guide rail is mounted along the left and right directions via the terminal fixing bracket. The electrical guide rail is mounted on the rear side of the front maintenance terminal mounting plate. It is parallel to the front maintenance terminal mounting plate and corresponds to the first square hole. A row of air switches can be snapped onto the electrical guide rail. The inner door has a second square hole along the left and right direction. When the inner door is closed, it can cover each air switch, and the operating part of each air switch can be exposed through the second square hole. Circuit breaker pressure plates are installed on both the upper and lower sides of the terminal fixing bracket. Each air switch is located between two circuit breaker pressure plates. The two circuit breaker pressure plates press the top and bottom of each air switch respectively to keep the air switches neat.

[0006] Based on the above, the terminal fixing bracket is a door frame-shaped plate with open front, top, and bottom sides. The left and right dimensions of the terminal fixing bracket are larger than the left and right dimensions of the first square hole. The front sides of the left and right side plates of the terminal fixing bracket are detachably connected to the rear side of the front maintenance terminal mounting plate. The terminal fixing bracket corresponds to the first square hole front and back. The electrical guide rail is installed on the front side of the rear side plate of the terminal fixing bracket. The upper and lower sides of the rear side plate of the terminal fixing bracket are provided with first horizontal folded edges that bend backward horizontally. The two circuit breaker pressure plates are symmetrically arranged above and below and are both installed on the two first horizontal folded edges by fastening screws.

[0007] Based on the above, the front side of the circuit breaker pressure plate located on the upper side of the circuit breaker is integrally formed with a U-shaped groove folded edge with the opening facing downward, and the U-shaped groove folded edge tightly presses against the top of the circuit breaker.

[0008] Based on the above, the front sides of both the left and right side plates of the terminal fixing bracket are integrally formed with outwardly bent vertical folded edges. The vertical folded edges are provided with a number of second elongated holes spaced vertically. The rear side of the front maintenance terminal mounting plate is provided with studs corresponding to the positions of each of the second elongated holes. Each of the second elongated holes is respectively fitted onto each of the studs. The studs are equipped with fastening nuts that fix and press the corresponding vertical folded edges tightly onto the front maintenance terminal mounting plate.

[0009] Based on the above, two cable management racks with vertical spacing are installed on the rear side of the front maintenance terminal mounting plate. The two cable management racks are respectively placed horizontally above and below each of the circuit breakers for organizing and fixing the wiring of each of the circuit breakers.

[0010] Based on the above, the front maintenance terminal mounting plate is provided with a plurality of circular holes spaced apart from left to right and located above the first square hole, the circular holes being used to install the corresponding air switch indicator lights.

[0011] This utility model has substantial features and advancements compared to existing technologies. Specifically, it improves the baffle of the traditional circuit breaker mounting assembly in a distribution cabinet into an inner door. The inner door is mounted on the front maintenance terminal mounting plate via a hinge. When closed, the inner door fits into the first square hole on the front maintenance terminal mounting plate. The inner door can be locked onto the front maintenance terminal mounting plate via a lock body. Thus, the inner door can cover each circuit breaker mounted on the electrical rail, while simultaneously allowing the operating parts of each circuit breaker to be exposed through the second square hole on the inner door, facilitating the operation of each circuit breaker. When maintenance of the circuit breaker is required, the inner door can be opened forward by unlocking the lock body for easy maintenance.

[0012] Furthermore, the design incorporates two circuit breaker pressure plates that press firmly against the top and bottom of each circuit breaker, ensuring that the circuit breakers are aligned and preventing them from tilting on the electrical guide rail due to pressure during operation.

[0013] Furthermore, the left and right side plates of the terminal fixing bracket are provided with vertical folded edges on their front sides, and several second elongated holes are designed on the vertical folded edges. The rear side of the front maintenance terminal mounting plate is provided with studs that cooperate with the second elongated holes. When the terminal fixing bracket is installed on the front maintenance terminal mounting plate, the installation position of the terminal fixing bracket can be adjusted up and down using the second elongated holes, thereby adjusting the air switch to the optimal position.

[0014] Furthermore, two cable management racks spaced vertically are installed on the rear side of the front maintenance terminal mounting plate. These cable management racks can be used to organize and fix the circuit breaker wiring, preventing the circuit breaker wiring from becoming loose and ensuring that the circuit breaker wiring is neat and orderly.
