[0046] The socket 100 for which protection is requested in this application is used to be electrically connected to a distribution box (not shown), so that the electricity generated by the generator when it is working can be used to supply power to the distribution box through the socket 100, and meet the use requirements of emergency power supply of the distribution box.

[0047] like Figures 1 to 5As shown, the socket 100 claimed in the present application comprises a metal shell 10, a socket module 20 and a connector assembly 30. The metal shell 10 is formed with a receiving cavity 101 inwardly, and a wire hole 110 is provided on the metal shell 10. The wire hole 110 is connected to the receiving cavity 101 and can be used for the access line on the distribution box to pass through; the socket module 20 is partially arranged in the receiving cavity 101 and connected to the metal shell 10 for plugging with an external power plug (not shown), wherein the power plug is used to be electrically connected to a generator (not shown); the connector assembly 30 is arranged corresponding to the wire hole 110 and is connected to the metal shell 10 The connector assembly 30 is a detachable connection, comprising a male connector 31, a first sealing gasket 32, and a female connector 33. The male connector 31 passes through the corresponding threading hole 110 and is then threadedly connected to the female connector 33. Furthermore, the male connector 31 and the female connector 33 can simultaneously press against the metal shell 10 to secure the connector assembly 30 to the metal shell 10. The first sealing gasket 32 ​​is disposed on the periphery of the threading hole 110 and abuts against the metal shell 10. Furthermore, the first sealing gasket 32 ​​can deform under the pressure of the male connector 31 or the female connector 33. The deformed first sealing gasket 32 ​​can assemble and seal the incoming wires passing through the first sealing gasket 32. In other words, an external generator can supply power to the distribution box through the socket 100 to meet the emergency power supply requirements of the distribution box.

[0048] As can be seen from the above, the assembly of the connector assembly 30 on the metal shell 10 is achieved through the threaded cooperation between the male connector 31 and the female connector 33, and the deformation of the first sealing gasket 32 ​​after being compressed can be used to seal the threading of the incoming wires on the metal shell 10, which can improve the waterproof sealing of the metal shell 10 and make the socket 100 suitable for outdoor working environments; in addition, the user can assemble the connector assembly 30 on the metal shell 10 without the aid of external tools, which is convenient for operation.

[0049] like Figure 2 、 Figure 3As shown, the metal shell 10 includes a main shell 11, a double-sided plate 12 and a cover plate 13. The double-sided plate 12 can be assembled on the main shell 11 in a plug-in manner and connected to the main shell 11; the cover plate 13 can be inserted between the main shell 11 and the double-sided plate 12 and connected to the main shell 11 and / or the double-sided plate 12 respectively. In addition, the main shell 11, the double-sided plate 12 and the cover plate 13 together enclose a receiving cavity 101. In other words, the metal shell 10 can be assembled by the main shell 11, the double-sided plate 12 and the cover plate 13. In this process, the double-sided plate 12 and the main shell 11 are assembled with each other by plug-in cooperation, and the cover plate 13 is also assembled between the main shell 11 and the double-sided plate 12 in a plug-in manner, which facilitates the assembly of the metal shell 10. Here, the main housing 11 and the two side panels 12 are connected by spot welding, and the cover 13 can be fixed to the cover 13 by screws 131 passing through the main housing 11. It should be noted that the socket module 20 partially protrudes outward relative to the main housing 11 and is connected to the main housing 11.

[0050] like Figure 2 、 Figure 5 As shown, the socket module 20 includes a socket body 21 and a flip cover 22. The flip cover 22 is rotatably mounted on the socket body 21. A torsion spring 23 is pre-deformed between the flip cover 22 and the socket body 21. The torsion spring 23 is used to drive the flip cover 22 to close onto the socket body 21. In other words, when an external power plug is not inserted into the socket body 21, the flip cover 22 can automatically close onto the socket body 21 under the drive of the torsion spring 23, thereby providing a waterproof seal for the socket body 21, thereby further improving the overall waterproof sealing performance of the socket 100. It should be noted that the specific structure of the socket body 21 and how it is plugged in and mated with the power plug to achieve electrical connection between the power plug and the socket body 21 can be specifically configured according to the actual use requirements and will not be elaborated here.

[0051] As preferably, Figure 5 As shown, the socket body 21 is equipped with a waterproof base 211, through which the power plug can be inserted and mated with the socket body 21. Furthermore, the flip cover 22 is equipped with a second sealing gasket 221, which can be driven by the flip cover 22 to abut against the waterproof base 211. This compression deformation of the second sealing gasket 221 further improves the waterproof seal between the flip cover 22 and the socket body 21. Here, the second sealing gasket 221 is configured as a foam pad, rubber pad, or the like.

[0052] like Figure 4As shown, the first sealing gasket 32 ​​is disposed on the outside of the metal housing 10 and abuts against the female connector 33. In other words, the sealing portion of the connector assembly 30 when the incoming wire is threaded through the metal housing 10 is disposed on the outside of the metal housing 10. This not only prevents water from entering the metal housing 10 and provides an effective waterproof seal, but also facilitates the assembly and connection of the connector assembly 30 on the metal housing 10.

[0053] like Figure 3 、 Figure 4 As shown, the number of wire holes 110 is configured to be multiple, and the multiple wire holes 110 are arranged on different walls of the metal shell 10; wherein, the connector assembly 30 also includes a sealing connector 34. When the sealing connector 34 is screwed onto the male connector 31, the sealing connector 34 can block the corresponding wire hole 110. In other words, the user can select one of the connector assemblies 30 according to their needs to pass the incoming wire through, while the male connectors 31 of the other connector assemblies 30 that are not for incoming wires are sealed with the sealing connector 34, so that the incoming wires on the distribution box can pass through the metal shell 10 from different directions. This facilitates the on-site installation of the socket 100 and prevents the incoming wires from excessive bending and deformation. It should be noted that when there are multiple connector assemblies 30, the multiple connector assemblies 30 include not only the female connector 33 but also the sealing connector 34. When the user needs to install the socket 100 on-site, they can select the appropriate connector assembly 30 according to the direction of the incoming wires on the distribution box. Here, threading holes 110 can be respectively opened on the two side plates 12 and the cover plate 13 of the metal shell 10 .

[0054] like Figure 1 As shown, the socket 100 also includes an indicator light 40, which is installed on the metal shell 10 and is electrically connected to the socket module 20, and the indicator light 40 can perform a lighting operation according to the working status of the socket module 20. In this way, the user can intuitively judge the working status of the socket module 20 by the lighting of the indicator light 40, which makes it easier for the user to obtain the working status of the socket 100 and improves the user's experience. Here, the working status of the socket module 20 includes the power-on state and / or the grounding state, that is, the power-on state and the grounding state of the socket module 20 can be reflected by the lighting operation of the indicator light 40, so as to facilitate the user's use of the socket 100. It should be noted that the specific structure of the indicator light 40 and how to correspond to the working principle of lighting according to the working status of the socket module 20 can adopt the existing conventional method, which will not be elaborated here.

[0055] In the present application, the socket 100 also includes a circuit board (not shown), which is electrically connected to the socket module 20; wherein, a varistor is integrated on the circuit board for overvoltage protection of the socket module 20. In this way, by utilizing the structural characteristics of the varistor, the socket 100 has the function of overvoltage protection and plays a role in lightning protection to meet the usage requirements of the socket 100 when used outdoors.

[0056] like Figure 3 As shown, the socket 100 also includes a ground support plate 51 and a ground pressure plate 52. The ground support plate 51 is fixedly installed in the metal shell 10 and electrically connected to the socket module 20. The ground pressure plate 52 and the ground support plate 51 are detachably connected by a connector (not shown) to press the ground wire in the incoming line onto the ground support plate 51. This can achieve grounding of the socket assembly and the metal shell 10 and facilitate operation. Here, the ground support plate 51 is connected to the metal shell 10 by spot welding, and the connector is specifically a bolt, screw, etc.

[0057] 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.

[0058] Those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present invention and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection claimed by the present invention.
