[0002] To ensure the safe and stable operation of electrical equipment under various harsh weather and environmental conditions outdoors, the equipment is typically installed in outdoor miniature circuit breaker (MCB) distribution boxes. However, current outdoor distribution boxes are selected based on the number of devices installed and have fixed sizes that cannot be expanded. If the equipment is not fully installed in the outdoor distribution box, the empty space on the side increases the risk of electric shock. Furthermore, each size of outdoor distribution box requires a separate production mold, resulting in high mold costs. Therefore, ensuring the robustness and reliability of outdoor distribution boxes under various outdoor conditions, allowing for flexible expansion of the box size according to the number of electrical devices required by the user, and using interchangeable components to reduce production mold costs are key design considerations. Summary of the Invention
[0003] In view of this, the purpose of this invention is to propose an expandable outdoor power distribution box to solve the problems that current outdoor power distribution boxes are selected according to the number of installed devices and have fixed sizes that cannot be expanded, and that each size of outdoor power distribution box requires a separate production mold, resulting in high costs.
[0004] To achieve the above objectives, the present invention provides an expandable outdoor power distribution box, comprising a base unit and an expansion unit; the base unit can be used alone or in conjunction with the expansion unit; the base unit includes a base, a cover, a face shield, a cover side plate, and a base side plate; the cover is disposed on the upper part of the base, the top of the cover has a first opening, and the face shield closes the first opening; the side of the cover has a second opening, and the cover side plate closes the second opening; the side of the base has a third opening, and the base side plate closes the third opening; one side of the expansion unit is connected to the base unit through the second opening and the third opening.
[0005] As a further improvement of this application, the expansion unit includes a rear expansion cover, an expansion mask, a front expansion cover, and an expansion base; the rear expansion cover and the front expansion cover are respectively connected to both ends of the second opening of the cover; the expansion base is connected to the third opening of the base; the expansion mask covers the top opening between the rear expansion cover and the front expansion cover; the cover side plate closes the side openings of the rear expansion cover and the front expansion cover; the base side plate closes the side openings of the expansion base.
[0006] As a further improvement to this application, the expansion unit can also be installed on an adjacent expansion unit.
[0007] As a further improvement of this application, the base, the cover, the cover side plate, the base side plate, the rear expansion cover, the front expansion cover and the expansion base are all made of ABS flame-retardant material by compression molding, and the face mask and the expansion face mask are made of PC material by compression molding.

Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0021] like Figures 1-5 As shown, an expandable outdoor power distribution box includes a base unit and an expansion unit; the base unit can be used alone or in conjunction with the expansion unit; the base unit includes a base 1, a cover 2, a face shield 3, a cover side plate 4, and a base side plate 5; the cover 2 is disposed on the upper part of the base 1, the top of the cover 2 has a first opening, and the face shield 3 closes the first opening; the side of the cover 2 has a second opening, and the cover side plate 4 closes the second opening; the side of the base 1 has a third opening, and the base side plate 5 closes the third opening; one side of the expansion unit is connected to the base unit through the second opening and the third opening.
[0022] By setting up basic and expansion units, the number of basic and expansion units can be selected according to requirements, allowing for more targeted selection based on the number of devices to be installed. Furthermore, during production, only two structural components—basic and expansion units—need to be manufactured, effectively reducing the variety of structural components required and significantly lowering mold costs.
[0023] Furthermore, the expansion unit includes a rear expansion cover 6, an expansion face shield 7, a front expansion cover 8, and an expansion base 9. For installability, the rear expansion cover 6 and the front expansion cover 8 are respectively connected to both ends of the second opening of the cover 2; the expansion base 9 is connected to the third opening of the base 1; the expansion face shield 7 covers the top opening between the rear expansion cover 6 and the front expansion cover 8; the cover side plate 4 closes the side openings of the rear expansion cover 6 and the front expansion cover 8; and the base side plate 5 closes the side opening of the expansion base 9.
[0024] The expansion unit can also be installed on an adjacent expansion unit, using the same installation method as when the expansion unit is installed on the base unit.
[0025] The base 1, the cover 2, the cover side plate 4, the base side plate 5, the rear expansion cover 6, the front expansion cover 8, and the expansion base 9 are all made of ABS flame-retardant material by compression molding, which ensures the flame retardancy and insulation of the power distribution box while also taking into account structural strength. The face shield 3 and the expansion face shield 7 are made of PC material by compression molding, which ensures transparency so that the internal installed products can be directly observed while also taking into account strength.
[0026] The base 1 and the base side plate 5 are connected by an inner mortise and tenon structure, and the cover 2 and the cover side plate 4 are connected by an inner mortise and tenon structure. The mortise and tenon connection effectively ensures the waterproof performance of the connected components. A face shield 3 is installed on the front of the cover 2, allowing direct observation of the status of the electrical components installed inside the outdoor distribution box. The electrical components inside the outdoor distribution box enter and exit through pre-drilled holes at the top and bottom of the base 1. The base 1 is equipped with standard 35mm mounting rails for installing the electrical components.
[0027] The rear expansion cover 6 and the front expansion cover 8 are connected between the cover 2 and the cover side plate 4 via a mortise and tenon structure. The expansion base 9 is connected between the base 1 and the base side plate 5 via a mortise and tenon structure. Additional electrical components can enter and exit through pre-drilled holes at the top and bottom of the expansion base 9. The number of expansions is not limited to the number shown in the figure; if the width of the outdoor distribution box needs to be further increased, the rear expansion cover 6, expansion cover 7, front expansion cover 8, and expansion base 9 can be added.
