Detailed Implementation

[0029] like Figures 1 to 3As shown, the present invention discloses a housing for a universal circuit breaker, comprising a housing body 1 and a faceplate 2 for mounting the universal circuit breaker within the housing body 1. Terminals 4 are provided at the upper end of the housing body 1, and an intelligent controller 5 is installed inside the housing body 1. The faceplate 2 is box-shaped, with its front surface 10 being an outwardly convex curved surface. This curved surface structure maintains stability and does not break under external pressure. Without affecting the appearance and dimensions, the curvature of the surface is designed to be relatively large; a larger curvature results in stronger pressure resistance, while also enhancing the aesthetics of the curved surface design. The faceplate 2 is fixed to the universal circuit breaker through the mounting holes 215 on the side wall fold. On the left side of the front of the faceplate 2, there is an intelligent controller window 209 for displaying the intelligent controller. On the center of the front of the faceplate 2, there is a trip button window 201 for displaying the trip button and a closing button window 202 for displaying the closing button, which correspond to the trip and closing buttons inside the circuit breaker. The trip and closing states are manually controlled. The trip button window 201 and the closing button window 202 are arranged on the left and right sides. Directly below the trip button window 201, there is a trip and closing status indicator window 204. Directly below the closing button window 202, there is an energy storage status indicator window 203. The status of the circuit breaker can be seen intuitively through the trip and closing status indicator windows 204 and the energy storage status indicator window 203. A circular anti-lock knockout hole 213 is provided directly above the trip button window 201. A secondary nameplate pasting groove 207 for pasting a secondary nameplate is provided on the lower center of the front of the faceplate 2. A main nameplate pasting groove 206 for pasting a main nameplate is provided on the upper right side of the front of the faceplate 2. A square mechanical counter knockout hole 212 is provided on the bottom surface of the main nameplate pasting groove 206. An identification pasting groove 208 is provided above the anti-lock knockout hole 213. A manual operation handle window 205 is provided between the closing button window 202 and the main nameplate pasting groove 206, exposing the manual operation handle 3. A sloping surface 6 for pulling out the manual operation handle 205 is provided on the upper right side of the manual operation handle window 205.

[0030] The mechanical counter knockout hole 212 and the anti-lock knockout hole 213 can be easily knocked out by tapping the grooves around the knockout hole with a tool, thus improving the efficiency of hole opening.

[0031] A semi-circular protruding padlock device 210 is provided between the trip button window 201 and the close button window 202. The padlock device 210 is integrally injection molded with the cover 2, and has a padlock hole. When the circuit breaker is closed, it can prevent accidental tripping; when the circuit breaker is open for maintenance, it can prevent closing, ensuring the safety of maintenance personnel and the circuit.

[0032] An anti-misoperation cover 211 is provided on the opening button window 201, the closing button window 202 and the intelligent controller window 209 respectively to block the window. The anti-misoperation cover 211 is made of transparent acrylic material and is hinged to each window. The anti-misoperation cover 211 covers the outside of the closing button, the opening button and the controller operation panel to prevent malfunctions caused by improper operation.

[0033] A heat dissipation grille 214 is provided on the bottom surface of the faceplate 2. The heat dissipation grille 214 is a horizontally equidistant strip opening. The heat dissipation grille is set at the bottom because hot air rises. Bottom ventilation helps to form natural convection, which can not only ensure air circulation, but also prevent foreign objects from entering, thus ensuring the stability and safety of the universal circuit breaker during operation.

[0034] like Figure 4 As shown, the manual operating handle 3 consists of a handle and a head. The upper part of the handle is cylindrical, with its outer wall surface being a streamlined curved surface suitable for hand grip, satisfying ergonomics. The upper part of the handle also features grip grooves 7 adapted to the fingers, increasing the friction between the operator's hand and the handle, improving grip comfort and stability, and preventing slippage during operation. The lower part of the handle is plate-shaped, with weight-reducing grooves 8 on both sides. The head is a disc with a central opening 9, and weight-reducing grooves 8 are distributed circumferentially on both sides of the disc. This plate-like structure reduces the overall weight of the handle while ensuring mechanical strength, saving materials and lowering manufacturing costs.

[0035] The embodiments of this utility model are not limited thereto. Based on the above content of this utility model, and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, this utility model can also be modified, replaced or changed in various other forms, all of which fall within the scope of protection of this utility model.
