[0002] With technological advancements, outdoor junction boxes, particularly those used in solar photovoltaic systems, are crucial components in these systems. Their performance and stability directly impact the stability and power generation efficiency of the entire system. Due to their specific nature, outdoor junction boxes are often installed outdoors year-round. These are particularly useful in solar photovoltaic systems, primarily for connecting solar panels and routing the energy generated by them to external circuits. In the field of electrical control, these junction boxes are used to house terminal blocks and other connection devices. This allows for the centralization of most wiring terminals, which are then connected to a control center for control and control. This makes wiring more convenient and organized, while also simplifying overall wiring. However, existing outdoor junction boxes generally suffer from poor overall waterproofing. When exposed to rain or fog, rainwater can easily flow into the box and damage related electrical components. Dust protection is also a concern due to poor sealing performance. Furthermore, existing outdoor junction boxes face challenges in terms of stability and reliability, including protection against high and low temperatures, UV radiation, corrosion resistance, and maintenance difficulties.

[0026] The following describes in detail embodiments of the present application in conjunction with the above-mentioned drawings. Examples of the embodiments are shown in the drawings, and the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the drawings are exemplary and are intended only to explain the present application and are not to be construed as limiting the present application.

[0027] Typical embodiments of this application are as follows: Figure 1 The outdoor junction box shown is mainly composed of a box body 10 and a cover body 20, and the cover body 20 covers the box body 10 to form a household junction box. The box body 10 and the cover body 20 can be covered and connected by other snap-fitting methods, or they can be fastened by adhesives, or they can be covered and connected by other tight fitting methods. Figure 2As shown, the box body 10 has a first area 111 and a second area 112, that is, the box body 10 is divided into two areas, the first area 111 and the second area 112. The first area 111 is sealed. The first area 111 of the box body 10 and the cover body 20 are covered so that the first area 111 is in a sealed state, and the electric contact piece 101 is arranged in the first area 111 in the sealed state, so that the electric contact piece 101 is fixed in the first area 111, so that when the outdoor junction box works outdoors, it can be waterproof and dustproof in the face of different climate conditions such as sun and rain; the cooperation between the first area 111 and the cover body 20 can also be achieved by other ways to achieve the sealing of the first area 111. A sealing ring 1112 is arranged between the first area 111 and the cover body 20, and the sealing ring 1112 is sandwiched between the cover body 20 and the first area 111, so that the sealing ring 1112 completely fills the gap between the first area 111 and the cover body 20, thereby improving the sealing performance of the first area 111. The electrical contact 101 can be considered a functional component of the outdoor junction box of the present application itself, that is, all the various functional components of the outdoor junction box that require waterproofing and dustproofing can be fixed in the first area 111. The area outside the first area 111 of the box body 10 is considered the second area 112, and the socket frame 160 is located in the second area 112. The socket frame 160 is provided with a wire insertion slot 120, which is used to plug in an external plug. The wire insertion slot 120 is provided with an electrical pin 123 inside. The electrical pin 123 is electrically connected to the electrical contact 101 in the first area 111. The wire insertion slot 120 is located in the second area 112, and there is no need to enter the waterproof first area 111. It is only electrically connected to the electrical contact 101 in the first area 111 through the electrical pin 123, that is, there is no need to enter the sealed area, which facilitates the wiring operation.

[0028] As another embodiment of the present application, refer to Figure 2 and Figure 5 It can be seen that the sleeve frame 160 in the second area 112 has a top edge 161 at the junction with the adjacent first area 111. The top edge of the side wall of the box body 10 corresponding to the first area 111 forms the top peripheral edge 162 of the box body 10. Corresponding to the top peripheral edge, the cover body 20 has a bottom vertical wall 25 that matches the top peripheral edge 162. A sealing ring 1112 is provided between the top peripheral edge 162 and the bottom vertical wall 25. This further improves the sealing performance of the first area 111 and its comprehensive waterproof and dustproof performance.

[0029] like Figure 6As shown, the second region 112 is provided with a socket frame 160, which is provided with a wire insertion slot 120. An electrical pin 123 is disposed within the wire insertion slot 120 and electrically connected to the corresponding electrical contact 101. The wire insertion slot 120 is located in the second region 112, and a through hole 122 is formed in the side wall 121 of the wire insertion slot 120. The through hole 122 passes through the first region 111 and the second region 112, and the electrical pin 123 is inserted into the through hole 122. The electrical pin 123 is electrically connected to the electrical contact 101, which is equivalent to the electrical pin 123 being disposed between the first region 111 and the second region 112. When inserted, the through hole 122 and the electrical pin 123 are tightly fitted, ensuring that moisture does not penetrate into the first region 111 from the wire insertion slot 120 in the second region 112.

[0030] like Figures 1 to 5 As shown, the sleeve frame 160 is provided with a top edge 161 at the junction with the adjacent first area 111, and the top edge 161 of the side wall of the box body 10 corresponding to the first area 111 constitutes the top peripheral edge 162 of the box body 10, and corresponding to the top peripheral edge 162, the cover body 20 is provided with a bottom vertical wall 25 matching the top peripheral edge 162, and a sealing ring is provided between the top peripheral edge 162 and the bottom vertical wall 25.

[0031] Typical embodiments of this application, Figure 1The outdoor junction box shown includes a box body 10 and a cover 20. The cover 20 is connected to the box body 10. When connected, the cover 20 seals the opening of the box body 10, allowing the box body 10 to be placed on a work surface, forming a seal between the work surface and the bottom of the box body. An electrical contact 101 is fixed within the box body 10 and can be understood as the main functional component of the outdoor junction box or the electrical connection terminal of the main functional component. The box body 10 is divided into a first area 111 and a second area 112. The first area 111 is provided with a circle of protruding edges 1111, which abut against the inner wall of the cover body 20. A sealing ring 1112 is provided on the protruding edges. The sealing ring 1112 is made of soft elastic material, so that the sealing ring 1112 is clamped between the protruding edges 1111 and the inner wall of the cover body 20, so that the cover body 20 and the first area 111 are in a sealed state, which can better prevent water and dust. In addition, the electric contact 101 is fixed in the first area 111, that is, the electric contact 101 or the main functional components in the junction box are located in this sealed area. The wire duct 120 is located in the second region 112. A through-hole 122 is defined in the bottom wall 121 of the wire duct 120, connecting the first region 111 and the second region 112. An electrical pin 123 is inserted through the through-hole 122 and electrically connected to the electrical contact 101. The electrical pin 123 extends between the first region 111 and the second region 112. The through-hole 122 and the electrical pin 123 fit tightly together when inserted, preventing moisture from seeping into the first region 111 from the wire duct 120. A plug 30 is also provided. The plug 30 includes a plug 301 and an electrical connector 302 exposed on the plug 301. The plug 301 is insertable into the wire duct 120. When the plug 301 is inserted into the wire duct 120, its electrical connector 302 electrically connects to the pin 123. The electrical connector 302 on the plug 301 of the plug cable 30 is electrically connected to the electrical contact 101 in the first area 111 via the pin 123. This allows the plug cable to function as an outdoor junction box, electrically connecting the plug cable to the junction box through the plug. This ensures that electrical components requiring waterproofing are located in the first area 111 for waterproofing and dustproofing, while also allowing the cable duct 120 to be located in the second area 112 for ease of daily operation and maintenance.

[0032] As another classic embodiment of the present application, Figure 2As shown, a slot 130 is provided at the top of the wiring trough, and a buckle 310 is provided on the plug 301 to mate with the slot 130. When the plug 301 is inserted into the wiring trough 120, the buckle 310 engages with the slot 130 and secures the plug 301 in the wiring trough 120, thereby electrically connecting the electrical connection portion 302 to the electrical pins 123 in the wiring trough 120. Since the plug 301 is tightly inserted into the wiring trough 120, a seal is ensured. Furthermore, since the plug 301 is located in the second area 112, separated from the sealed first area 111, it is very convenient to operate the plug 301 when inserting and removing it from the wiring trough.

[0033] As a further embodiment of the present application, Figure 3 and Figure 4 As shown, the structure of the card slot 130 is that a square slot 1301 is provided on the top of the wire insertion slot 120, and the front half of the square slot 1301 is connected to an arch 1302, and the square slot 1301 and the arch 1302 are connected and surrounded to form a card slot 130. After the buckle 310 on the plug 301 passes through the square slot 1301, the hook 3101 of the buckle 310 buckles the arch 3102, so that the plug is firmly plugged into the wire insertion slot. Since the card slot 130 and other related components are located in the second area 112 instead of the first area 111, they are not related to the first area 111 when the plug is plugged in or out, which facilitates operation. The outdoor junction box can achieve the purpose of sealing and is easy to operate and maintain. In order to make the plugging and unplugging operations more convenient, as Figure 4 As shown, the cover 20 is provided with a resilient button 210, which has a latching portion 211 abutting against the latch 310. When the resilient button 210 is pressed, the latching portion 211 pushes the latch 310 out of the slot 130, disengaging the plug and the wiring duct from their interlocking engagement. The plug can then be easily removed from the wiring duct by pulling it outward. Specifically, after the plug is inserted into the wiring duct, the latch and the slot 130 engage, and the resilient button 210 allows the latch to be easily removed from the slot 130. Although the resilient button 210 is a feature on the cover, it corresponds to the second area of ​​the box body. Operation of the resilient button 210 also occurs in the second area, independent of the first area. This ensures that the outdoor junction box is both sealed and waterproof while facilitating plug insertion and removal, and also facilitates maintenance of the plug, wiring duct, and other related components.

[0034] As a classic embodiment of this application, Figure 2 and Figure 5As shown, the bottom wall of the wiring trough is provided with two through holes, and both of the through holes pass through the first area and the second area. By inserting an electric pin into each of the two through holes, two electric pins can be arranged, and the two electric pins are electrically connected to an electric contact 101 respectively, and the two electric pins are both between the first area and the second area. An electric contact holder 1011 is provided in the first area for mounting the electric contact 101, and the electric contact 101 is fixed in the electric contact holder 1011. In a more typical embodiment, two electric contact holders 1011 can be provided, and an electric contact 101 is provided in each electric contact holder 1011, that is, there are two electric contacts 101, and the two electric contacts 101 are electrically connected to two electric contact pins respectively. As another specific embodiment, as Figure 1 As shown, the electric contact holder 1011 is provided with a connecting post, and the electric contact 101 is provided with a connecting hole, which is sleeved on the connecting post so that the electric contact 101 is fixedly arranged in the electric contact holder 1011. The electric contact 101 can be sleeved on the connecting post through the connecting hole, so that the electric contact 101 can be firmly arranged in the first area.

[0035] As another embodiment of the present application, Figure 1 and Figure 6 As shown, when the outdoor junction box is installed on a work surface, the first area can also be filled with a waterproof colloid. That is, the waterproof colloid fills the entire space of the first area. All components in the first area, including the electrical contacts 101 and the electrical contact holder 1011, are encapsulated by the waterproof colloid, thereby further improving the overall waterproof performance. This embodiment can achieve its waterproof function even without being installed on a work surface. Alternatively, this embodiment can be implemented using a second embodiment, wherein the box body is provided with a bottom plate (not shown) to seal the bottom of the box body, and a second sealing ring is sandwiched between the box body and the bottom plate. Similarly, it can achieve good waterproof performance even without being installed on a work surface. To improve the connection between the box body and the cover, multiple latches 140 are provided on the outer wall of the box body, and multiple hooks 201 are provided on the cover. When the box body and the cover are connected, the hooks 201 engage the latches 140. When the two are engaged, the tightness of the connection between the box body and the cover is greatly improved. The holder 140 is provided on the outer wall of the box body. Two holders 140 can be provided on each outer wall. A corresponding number of hooks 201 are provided on the corresponding cover body. Each hook 201 corresponds to a holder 140. The hooks 201 have hook-shaped components that hook onto the holder 140, thereby tightly connecting the cover body and the box body, improving the overall sealing performance of the outdoor junction box and thus improving its waterproof and dustproof performance. The box body 10 is provided with a bottom plate to seal the box body, and a second sealing ring is sandwiched between the box body and the bottom plate.

[0036] The above description is only part of the implementation methods of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.

[0037] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
