[0036] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] It should be noted here that in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0038] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0039] See also Figure 1-2 As shown, the electrical appliance box 100 conforms to the embodiment of the utility model. The electrical appliance box 100 has a simple structure and is easy to install.

[0040] The electrical box 100 includes a box body 1, an electrical board 2 and a top cover 33. The box body 1 includes a bottom wall 11 and a side wall 12, and the bottom wall 11 and the side wall 12 are surrounded to form an installation space 13, and the electrical board 2 is installed in the installation space 13. The electrical board 2 includes a board body 21 and a terminal 22 arranged on the board body 21.

[0041] See also Figure 3 to Figure 5 As shown, the side wall 12 is provided with an installation opening 120 connected to the installation space 13, and the installation opening 120 includes a bottom surface 1201, a guide surface 1202 and a side surface 1203. The bottom surface 1201 is arranged close to the bottom wall 11, the side surface 1203 is arranged at both ends of the bottom surface 1201, and the guide surface 1202 is arranged at the position where the bottom surface 1201 and the side surface 1203 are connected.

[0042] Specifically, the guide surface 1202 is formed to extend from the bottom surface 1201 into the installation space 13, and the terminal 22 abuts against the guide surface 1202 and slides into the installation opening 120 through the guide surface 1202. This design can ensure that the terminal 22 can smoothly enter along the guide surface 1202 when inserted into the installation opening 120, avoiding collision or scratching between the terminal 22 and the edge of the installation opening 120, which helps to extend the service life of the terminal 22 and improve the reliability of the electrical equipment. When installing the electrical board 2, the installer does not need to accurately align the installation opening 120, but only needs to bring the electrical board 2 close to the installation opening 120, and the terminal 22 will enter the installation opening 120 along the guide surface 1202, which greatly simplifies the installation process and reduces the difficulty of installation.

[0043] A positioning column 14 is provided between two adjacent side walls 12, and the positioning column 14 protrudes into the installation space 13 to form an arc-shaped protrusion. The side surface 1203 is a plane, located on the arc-shaped protrusion, and is recessed from the arc-shaped protrusion in a direction away from the installation opening 120, and the projection of the guide surface 1202 on the bottom wall 11 is located within the projection range of the positioning column 14 on the bottom wall 11. The provision of the positioning column 14 strengthens the connection between the two adjacent side walls 12, improves the overall structural stability of the electrical box 100, and enables the electrical box 100 to better resist deformation when subjected to external forces, thereby extending the service life of the electrical box 100.

[0044] Furthermore, the installation opening 120 divides the side wall 12 into an upper side wall 121 and a lower side wall 122, the upper side wall 121 includes a first plane 1211 facing the installation space 13, and the lower side wall 122 includes a second plane 1221 facing the installation space 13, and the first plane 1211 and the second plane 1221 are flush. The flush design of the first plane 1211 and the second plane 1221 makes the appearance of the electrical box 100 more neat and beautiful, which meets the aesthetic requirements of modern electrical equipment. And when installing the electrical board 2, the field of vision is not blocked, making the installation of the electrical board 2 more convenient.

[0045] In this example, see Figure 8-Figure 9 As shown, the terminal 22 includes a head 221 exposed from the plate body 21, and a guide surface 2211 is provided on one side of the head 221 facing the installation opening 120, and the guide surface 2211 is configured to guide the terminal 22 into the installation opening 120. The provision of the guide surface 2211 enables the terminal 22 to enter the installation opening 120 more smoothly during the installation process, thereby improving the installation efficiency.

[0046] See also Fig.10 As shown, the board body 21 includes a first board 211 and a second board 212 which are stacked, the terminal 22 is arranged on the first board 211, and the terminal 22 is arranged toward the mounting opening 120 so as to be connected with an external connector or cable.

[0047] In this embodiment, the first plate 211 is located below the second plate 212, and the shapes of the four corners of the first plate 211 match the shape of the positioning column 14, further limiting the displacement of the electrical board 2 in the installation space 13, making the installation and fixation of the electrical board 2 more stable.

[0048] The box body 1 also includes a plurality of support portions 15 disposed in the installation space 13 and circumferentially disposed along the side wall 12, and the support portions 15 are configured to carry the board body 21. The arrangement of the support portions 15 can increase the stability of the electrical board 2 in the installation space 13 and prevent it from shaking or shifting during operation.

[0049] Furthermore, in this embodiment, the support portion 15 includes a horizontal portion and a vertical portion. When placing the electrical board 2, the electrical board 2 is placed on the horizontal portion, and the edge of the electrical board 2 abuts against the vertical portion, thereby limiting the horizontal position of the electrical board 2 and limiting the length of the terminal 22 protruding toward the mounting opening 120.

[0050] In other embodiments, the support portion 15 may also be provided with only a horizontal portion, in which case the edge of the electrical board 2 directly abuts against the side wall 12 of the box body 1. The support portion 15 may be designed as required, and the present invention is not limited thereto.

[0051] The box body 1 is provided with a first positioning portion 111, and the electrical board 2 is correspondingly provided with a second positioning portion 2111, and the first positioning portion 111 and the second positioning portion 2111 are positioned and clamped. Such a design can realize the precise positioning of the electrical board 2 in the box body 1, and improve the installation accuracy and stability.

[0052] In this embodiment, the first positioning portion 111 is an elastic buckle provided on the bottom wall 11 and extending into the installation space 13, and the second positioning portion 2111 is a snap-in hole provided on the plate body 21. The design of the elastic buckle allows it to deform when subjected to a certain pressure, so that it can be smoothly snapped into the snap-in hole. Once snapped in, the elastic buckle will return to its original shape and tightly fasten the snap-in hole, ensuring the stability of the electrical board 2 in the box body 1 and enhancing the connection strength between the electrical board 2 and the box body 1. When the electrical board 2 needs to be disassembled for maintenance or replacement, it only needs to apply a certain force to deform the elastic buckle, and the electrical board 2 can be easily removed from the box body 1. This design makes the disassembly process also simple and quick.

[0053] For details, please refer to Figure 7 As shown, the elastic buckle includes two semicircular buckles, so that there is no direction requirement during assembly, simplifying the installation process. A retreat groove 1111 and a connecting rib 1112 are provided between the two semicircular buckles, and the two semicircular buckles are connected by the connecting rib 1112, so that deformation can be reduced during molding. During installation, the two semicircular buckles move closer to the middle until they enter the snap-on hole smoothly, and then the two semicircular buckles return to their original state.

[0054] A fixing column 112 is provided on the bottom wall 11, and a fixing hole 2112 is correspondingly provided on the electrical board 2, and a fastener 2113 passes through the fixing hole 2112 and is fixedly connected to the fixing column 112. The fixing hole 2112 is provided on the first plate 211, and an avoidance portion 2121 is provided at a position of the second plate 212 corresponding to the fixing hole 2112. Such a design can achieve a firm fixation of the electrical board 2 in the box body 1, and prevent it from loosening or falling off during operation. The setting of the avoidance portion 2121 can ensure that the fastener 2113 can smoothly pass through the fixing hole 2112 and be connected to the fixing column 112, and will not cause damage to the second plate 212.

[0055] The electrical box 100 further includes a top cover 3, which is provided with a connection hole 31 at a position corresponding to the positioning column 14, and a connection member 32 passes through the connection hole 31 and is fixedly connected to the positioning column 14. The arrangement of the top cover 3 can protect the electrical board 2 from the influence of the external environment and improve the overall performance of the electrical device.

[0056] During the installation process of the present embodiment, the electrical board 2 is first placed obliquely in the installation space 13 of the box body 1, so that the terminal 22 of the electrical board 2 first abuts against the guide surface 1202, and enters the installation opening 120 along the guide surface 1202 until the edge of the electrical board 2 abuts against the vertical part of the support portion 15. Then the electrical board 2 is slowly leveled until the elastic buckle smoothly enters the snap-in hole, indicating that the electrical board 2 is installed in place. Next, the electrical board 2 is fixedly connected to the fixing column 112 on the bottom wall 11 by the fastener 2113 to further ensure the stability of the electrical board 2. Finally, the top cover 3 is covered on the box body 1, and the top cover 3 is fixedly connected to the positioning column 14 by the connector 32 to complete the installation of the entire electrical box 100.

[0057] To sum up, the electrical box 100 of the utility model carries and guides the terminal 22 by setting a guide surface 1202, ensuring that the terminal 22 maintains the correct direction and position during the installation process, so that the terminal 22 can smoothly enter the installation port 120, reduce the friction and collision between the terminal 22 and the edge of the installation port 120, and effectively extend the service life of the terminal 22, thereby allowing the electrical board 2 to be quickly and conveniently installed in the electrical box 100, greatly improving the installation efficiency.
