It is apparent that the described embodiments are only a part of the embodiments of the present application, rather than all embodiments. Based on the embodiments disclosed in the present application, all other embodiments that a person skilled in the art can obtain without inventive labor are within the scope of protection of the present application.

The outdoor power supply box shown inFIGS.1-6includes a housing10, a panel40assembled inside the housing10, sockets33, and three protectors32. Furthermore, it also includes a waterproof component20set on the front side of the housing10. The housing10consists of a base box101with an open top and a cover102rotatably mounted on the top of the base box101. The cover102covers the top of the base box101, preventing insects, debris, and other contaminants from entering the housing10and causing pollution or damage to the power supply box.

Specifically, one side of the cover102is provided with a pivot103, and the base box101is equipped with a connecting groove104that engages the pivot103, allowing the cover102to rotate around the pivot103. In the description, the side with the pivot103and the connecting groove104is referred to as the rear side.

On the front side of the housing10, a detachable cavity for cable insertion is provided. The cavity is formed by two arc-shaped slots105, which are located at the front connection between the base box101and the cover102. When the base box101is fastened to the cover102, the cavity is formed.

Specifically, three arc-shaped distributed locking slot1052and guiding grooves1051are provided on the groove walls of the two slots105. After the housing10is fastened, the locking slot1052and guiding grooves1051of the two slots105form a circular structure distribution.

Refer toFIGS.3-4for a detailed explanation of the waterproof component20.

The waterproof component20includes a hard first casing201, a second casing202, a soft first waterproof sleeve203, and a second waterproof sleeve204. The first waterproof sleeve203is inserted into the first casing201and connected to the slot105of the base box101, while the second waterproof sleeve204is mounted on the second casing202and connected to the slot105of the cover102.

Both the first casing201and the second casing202are made of nylon, while the first waterproof sleeve203and the second waterproof sleeve204are made of polyurethane, rubber, or silicone material. As long as the first waterproof sleeve203and the second waterproof sleeve204are made of flexible material and have an interference fit with the cable, they can be used.

Multiple snap clasps2012(connection parts) that match the locking slot1052and guiding blocks2011that match the guiding groove1051are provided on the rear side of the first casing201and the second casing202. The first casing201is inserted into the slot105of the cover102by matching the snap clasps2012with the locking slot1052, and the second casing202is inserted into the slot105of the base box101by matching the snap clasps2012with the locking slot1052.

It should be noted that in this embodiment, snap clasps and connecting slots are used for connection. However, as long as the first casing and the second casing can be detachably mounted on the housing and the cover, other forms of connection, such as bolts or rivets, can also be used.

The first casing201, the second casing202, the first waterproof sleeve203, and the second waterproof sleeve204are all arc-shaped structures. When the housing10is fastened, the first casing201and the second casing202form a space for accommodating cables. The bottom of the first waterproof sleeve203and the second waterproof sleeve204are equipped with a downward-extending limiting wall207. The first casing201and the second casing202are equipped with grooves and protrusions206that match the limiting wall207, and the limiting wall207has an insertion hole for the protrusions206.

When the limiting walls207of the first waterproof sleeve203pass through the slots, the protrusions206are inserted into the slots to complete the installation of the first waterproof sleeve203. Multiple upward-extending sealing walls205are provided on the inner wall of the first waterproof sleeve203, forming a concave surface. The sealing walls205are also arc-shaped structures that fit tightly around the cables, with the diameter of the sealing walls205gradually increasing from front to back.

Specifically, the first waterproof sleeve203has three sealing walls205, with the frontmost sealing wall205being the shortest in length and radius, and the rearmost sealing wall205having the longest radius. The structure of the first waterproof sleeve203is the same as that of the second waterproof sleeve204. When the housing10is fastened, the sealing walls205on the first waterproof sleeve203and the second waterproof sleeve204merge into multiple circular sealing walls205, providing a better fit for cables of different radii and greatly increasing the overall sealing effect for better waterproofing.

Furthermore, within the base box101, there are three protectors32, installation plates31that support and fix the protectors32, and supporting walls30. The installation plates31are set between the two supporting walls30, and the three protectors32are inclined on the installation plates31, with sockets33set beside the protectors32.

The inner wall of the base box101is equipped with supporting blocks1011and locking blocks1012for connecting the panel40. The locking blocks1012are set above the supporting blocks1011and abut against the top surface of the panel40. The end of the supporting blocks1011is also equipped with limiting blocks1013, and the bottom of the panel40has raised portions401that correspond to and match the limiting blocks1013.

The back of the bottom of the panel40abuts against the limiting blocks1013, with the raised portions401locked by the limiting blocks1013, and the locking blocks1012abut against the top of the panel40to prevent displacement. There are cable connection channels106on the front, left, and right sides of the base box101, and waterproof connectors are also provided at the channels106.

Preferably, the panel40also has multiple windows402for observing the indicator lights of the protectors32. The sockets33are fixed to the bottom of the panel40with bolts, and the protectors32are set below the panel40. The panel40has three windows402that align with the indicator light positions of the protectors32, allowing direct observation of the indicator lights when the cover102is open.

Among them, the three protectors32are respectively leakage protector32, overvoltage protector32, and overcurrent protector32, greatly increasing the safety of the power supply box.

Users can directly observe the indicator light status of the protector32through window402, which is highly reliable.

In particular, there are vertical raised edges107on the left and right side walls of the base box101and on the top surface of the front side wall. The top of the raised edge107is provided with an extension portion108extending outward (outside the cavity of the base box101). The angle between the extension portion108and the raised edge107can be 30-90°. When water infiltrates into the base box101from the connection between the base box101and the cover102, the extension portion108can effectively block the water and drain it out.

It should be noted that the raised edge107is set on the side closer to the opening of the base box101, that is, the inner side of the side wall.

The above-described embodiments are merely descriptions of preferred embodiments of the present application and do not limit the conception and scope of the present application. Various modifications and improvements made by those skilled in the art to the technical solutions of the present application, without departing from the design concept of the present application, should fall within the protection scope of the present application.
