[0049] The metal socket box 100 for which protection is sought in this application is used in RVs, campers, and other application scenarios requiring temporary power connection.

[0050] like Figure 2 、 Figure 3 、 Figure 6 and Figure 7As shown, the metal socket box 100 provided by the present application includes a housing assembly 10, a socket module 20 and a power indicator light 30. The housing assembly 10 includes a bottom shell 11, a bottom cover 12, a top cover 13 and a panel 14. The bottom cover 12 is assembled to the bottom of the bottom shell 11 in a plug-fitting manner and is welded to the bottom shell 11. The top cover 13 is assembled to the top of the bottom shell 11 in a plug-fitting manner and is welded to the bottom shell 11. The panel 14 is assembled into the bottom shell 11 and abuts against the bottom cover 12 and the top cover 13 respectively. In addition, the bottom shell 11, the top cover 13, the bottom cover 12 and the panel 14 are connected. The two panels 14 and 15 are enclosed together to form a receiving cavity (not shown); the socket module 20 is partially arranged in the receiving cavity and connected to the panel 14, for plugging with an external power plug (not shown); the power indicator light 30 is installed on the panel 14 and electrically connected to the socket module 20, and the power indicator light 30 can illuminate when the socket module 20 is powered on; wherein, a threading hole 110 is provided on the bottom cover 12 and / or the top cover 13, and the threading hole 110 can allow an external power cord (not shown) to extend into the receiving cavity and electrically connect the power cord to the socket module 20. Here, the number of power indicator lights 30 is configured to be multiple, and multiple power indicator lights 30 can emit green light outward when working. It should be noted that the working principle of how the power indicator light 30 illuminates according to the power-on status of the socket module 20 can adopt the existing conventional method, which will not be elaborated here.

[0051] As can be seen from the above, by assembling and connecting the bottom cover 12, the top cover 13 and the panel 14 in the bottom shell 11, it is not only convenient to assemble the housing assembly 10, but also the waterproof sealing performance of the housing assembly 10 as a whole can be improved; in addition, the power indicator light 30 is used to illuminate the power-on status of the socket module 20, which makes it easier for the user to obtain the working status of the metal socket box 100, thereby improving the user experience.

[0052] like Figure 5 As shown, a plurality of positioning protrusions 111 are formed on the bottom shell 11, and at least two of the plurality of positioning protrusions 111 are provided on the upper and lower sides of the panel 14 and respectively abut against the panel 14, for limiting the panel 14 in the bottom shell 11 and realizing the assembly limit of the panel 14 when assembled in the bottom shell 11, so that the panel 14 can be inserted into the bottom shell 11 along the gap between the two positioning protrusions 111. This not only facilitates the assembly of the panel 14 in the bottom shell 11, but also meets the use requirements of the assembly limit of the panel 14 in the bottom shell 11. Here, the positioning protrusion 111 is configured as a hemispherical shape.

[0053] As preferably, Figure 5As shown, there are four positioning protrusions 111, two of which are arranged in a group on both sides of the panel 14, so that the bottom shell 11 can be assembled and limited on both sides of the panel 14, which can further improve the stability of the panel 14 when assembled and limited in the bottom shell 11. Here, the positioning protrusions 111 are provided on the side of the bottom shell 11 close to the top cover 13.

[0054] like Figure 1 、 Figure 3 and Figure 6 As shown, the bottom cover 12 includes a bottom plate 121, and the four sides of the bottom plate 121 are bent toward the direction of the top cover 13 and formed with bent plates 122, that is, the four sides of the bottom plate 121 are formed with bent plates 122; wherein, three bent plates 122 are respectively attached to the bottom shell 11 and spot-welded to the bottom shell 11, and the panel 14 is attached to the remaining bent plate 122 and connected to the corresponding bent plate 122 through a connector 141. In other words, the bottom cover 12 can be inserted into the bottom shell 11 by attaching three of the bent plates 122 to the bottom shell 11, and then assembled and connected to the bottom shell 11 by spot welding. This facilitates the assembly of the bottom cover 12 on the bottom shell 11 and ensures the waterproof sealing between the bottom cover 12 and the bottom shell 11. Here, the connecting member 141 can pass through the panel 14 and be screwed to the corresponding bent plate 122 on the bottom cover 12 to fix the panel 14 to the bottom cover 12. This can improve the stability of the assembly of the panel 14 in the bottom shell 11. Specifically, the connecting member 141 can be configured as a bolt, screw, etc.

[0055] like Figures 1 to 3 、 Figure 7 As shown, the top cover 13 is mounted on the bottom shell 11 and connected to the bottom shell 11 by spot welding, thereby achieving an assembly connection of the top cover 13 on the bottom shell 11, thereby ensuring waterproof sealing between the top cover 13 and the bottom shell 11 during assembly.

[0056] like Figure 1 、 Figure 3 As shown, the housing assembly 10 further includes a cover plate 15, which is rotatably mounted on the bottom shell 11 and is used to cover the power plug that is plugged into the socket module 20 and play a role in waterproof sealing, thereby further improving the waterproof sealing of the metal socket box 100 when in use.

[0057] As preferably, Figure 1 、 Figure 3As shown, a boss 151 is formed on the cover plate 15. When the cover plate 15 covers the socket module 20, the boss 151 is disposed toward the socket module 20 and protrudes away from the socket module 20. In other words, the boss 151 increases the space for accommodating a power plug when the cover plate 15 is closed and mated with the socket module 20, thereby enabling the cover plate 15 to accommodate a power plug with a handle.

[0058] like Figure 2 、 Figure 3 As shown, the number of socket modules 20 is configured as multiple, and the current values ​​of the multiple socket modules 20 when powered on are different to meet different power usage requirements. Here, the number of socket modules 20 is configured as three, and the current values ​​of the three socket modules 20 when powered on are 20A, 30A and 50A respectively.

[0059] like Figure 3 As shown, the metal socket box 100 also includes a terminal 40 made of aluminum. The terminal 40 is mounted on the base housing 11 and electrically connected to the socket module 20. The terminal 40 is used to ground the socket module 20 and the base housing 11, allowing the ground wire in the external power cord to be directly connected to the terminal 40. This facilitates grounding of the metal socket box 100 and utilizes the low material cost of aluminum, which reduces grounding costs compared to copper. Here, the ground wire in the power cord can be directly fixed to the terminal 40 using a first machine screw 41.

[0060] like Figure 3 、 Figure 4 As shown, the number of terminal posts 40 in the metal socket box 100 of the present application is configured as two, one of the terminal posts 40 can be directly fixed to the bottom shell 11 by two second machine screws 42, and the other terminal post 40 is first assembled to the two terminal post fixing blocks 43 by the third machine screw 44, and the terminal post fixing block 43 is fixed to the bottom shell 11 by the fourth machine screw 45, thereby realizing the assembly connection of the two terminal posts 40 on the bottom shell 11.

[0061] like Figure 2 、 Figure 3 As shown, the metal socket box 100 also includes a grounding indicator light 50, which is mounted on the panel 14 and electrically connected to the socket module 20. Furthermore, the grounding indicator light 50 illuminates when the socket module 20 is grounded. In other words, when the metal socket box 100 is in operation, the illumination of the grounding indicator light 50 indicates the grounding status of the socket module 20. This makes it easier for users to determine the grounding status of the metal socket box 100, thereby enhancing the user experience.

[0062] like Figure 2 、 Figure 3As shown, the metal socket box 100 also includes a lightning protection module 61 and a lightning protection indicator light 62. The lightning protection module 61 is mounted on the base housing 11 and electrically connected to the socket module 20, providing overvoltage protection for the socket module 20. The lightning protection indicator light 62 is mounted on the lightning protection module 61 and can illuminate when the socket module 20 is in overvoltage protection mode. In other words, the metal socket box 100 has an overvoltage protection function, which can be indicated by the illumination of the lightning protection indicator light 62. This makes it easier for users to understand the overvoltage protection status of the metal socket box 100, thereby improving the user experience. Here, the lightning protection indicator light 62 can be displayed by emitting red light. It should be noted that the lightning protection module 61 can specifically use a varistor for overvoltage protection, and the operating principle of how the lightning protection indicator light 62 illuminates according to the overvoltage protection status of the lightning protection module 61 can be conventionally implemented and will not be elaborated here.

[0063] like Figure 2 、 Figure 3 As shown, the metal socket box 100 also includes a circuit breaker module 70, which is electrically connected to each of the multiple socket modules 20 to provide overload and short-circuit protection for each socket module 20 to meet user needs. The circuit breaker module 70 can be secured to the base housing 11 via a support bracket 71. It should be noted that the structure of the circuit breaker module 70 and the operating principle of how it provides overload and short-circuit protection for the socket modules 20 during operation can be implemented using conventional methods and will not be elaborated upon here.

[0064] like Figure 3 As shown, the metal socket box 100 also includes a sealing sheet 80, which is removably attached to the bottom cover 12 and / or the top cover 13 and is positioned corresponding to the wire threading holes 110. Furthermore, the sealing sheet 80 is designed to fit over the power cord passing through the corresponding wire threading holes 110, thereby ensuring a tight seal between the power cord and the sealing sheet 80. This improves the overall waterproof seal of the metal socket box 100, meeting the requirements of outdoor use. The sealing sheet 80 is removably secured to the bottom cover 12 and / or the top cover 13 via screws 81. It should be noted that when the wire threading holes 110 are not used for threading a power cord, the corresponding wire threading holes 110 can be sealed with a fully enclosed cover 90.

[0065] The technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
