The embodiment of the application also provides a socket. The socket mentioned in the embodiments of the present application includes both a fixed socket fixed on a wall and a movable socket, such as a power extension socket, a track socket, a socket converter, etc.

As shown in fig. 6, the socket includes a housing 100, the above-described key switch 200, and a socket assembly. The socket assembly is electrically connected to the key switch 200 and disposed inside the housing 100. The housing 100 has a mounting hole 121 on a panel thereof, the key switch 200 is positioned in the mounting hole 121 and the lamp housing 220 is exposed from the mounting hole 121. The mounting hole 121 is a through hole formed in the panel of the housing 110 and adapted to the structure of the lamp housing 220, and the openings of the lamp housing 220 and the receiving cavity 231 of the bracket 230 correspond to the mounting hole 121.

The bracket 230 is fixed between the panel of the attachment 120 and the bottom cover, the opening of the receiving cavity 231 faces the panel of the attachment 120, and the frame of the receiving cavity 231 (i.e., the sidewall of the bracket 230) is connected or adjacent to the inner side of the panel of the attachment 120 to reduce light leakage, so that the light emitted from the light emitting device 213 will not diffuse around. It should be noted that, in order to reduce light leakage as much as possible, it is preferable that there is no gap between the holder 230 and the inner side of the panel of the attachment 120, but in practice there may be some small gap.

As shown in fig. 8, in some implementations of the embodiments of the present application, the main body 110 has a rectangular parallelepiped structure, and the auxiliary member 120 is connected to the side of the main body 110 where the long side is located, so as to form a "product" shape structure. This enables the socket to occupy only a small space on the power socket when the socket is a socket converter.

In the embodiment of the present application, the main body 110 and the auxiliary body 120 may be connected together in an integrally formed manner, a panel including the main body 110 and a panel including the auxiliary body 120 are connected together in an integrally formed manner, side walls of the main body 110 and side walls of the auxiliary body 120 are connected together in an integrally formed manner, and a bottom cover of the main body 110 and a bottom cover of the auxiliary body 120 are connected together in an integrally formed manner, so that strength and aesthetic appearance of the housing 100 of the socket are enhanced, and the housing 100 is convenient to manufacture and assemble.

When the socket in the embodiment of the present application is a mobile socket such as a socket adapter, the socket adapter can be connected to a power socket through a plug assembly 300, one end of the plug assembly 300 is fixed inside the housing 100, and the other end of the plug assembly extends out of the housing 100. In the embodiment of the present application, the latch assembly 300 has the following two configurations:

the first method comprises the following steps: as shown in fig. 11, the plug pin assembly 300 is disposed on the main body 110, and the pin holders (not shown) of the plug pin assembly 300 are connected to the socket assembly, so as to fix the plug pin assembly 300 on the main body 110. This connection is the connection between the plug assembly 300 and the socket assembly, which is common in the socket adapter of the related art, and is not described herein again.

And the second method comprises the following steps: as shown in fig. 9, in some implementations of the embodiments of the present application, the pin assembly 300 of the socket is located in the attachment part 120, and the pin piece of the pin assembly 300 protrudes from the bottom side of the attachment part 120, and the pin piece holder 310 of the pin assembly 300 is connected to the bracket 230 in the extending direction of the pin piece.

In a second connection, as shown in fig. 7, the bracket 230 has a first engagement structure 236 on a side thereof near the bottom side of the attachment 120, for example, the first engagement structure 236 may be a protrusion. As shown in fig. 10, the bottom of the pin holder 310 of the latch assembly 300 has a second engaging structure 311, and the second engaging structure 311 is correspondingly matched with the first engaging structure 236. For example, the second engagement structure 311 may be a groove, and the protrusion may be embedded in the groove to fix the pin holder 310 on the bracket 230. When the bottom cover of the sub-body 120 is assembled, the structure of the receptacle converter is as shown in fig. 12.

Compared with the first connection mode, the second connection mode can avoid other jacks on the power socket after the socket converter is connected with the power socket. For example, for a five-pole power socket, when the plug pin assembly 300 is located in the main body 110, if the plug pin assembly 300 is inserted into a three-pole jack located below the power socket, the auxiliary part 120 may block the remaining two-pole jack on the power socket, thereby affecting the use of other jacks; conversely, when the plug pin assembly 300 is positioned in the appendage 120, if the plug pin assembly 300 is inserted into a three-pole jack positioned below on an electrical outlet, the remaining two-pole jack on the electrical outlet may continue to be used.

The key switch 200 and the socket function module of the socket assembly share the same plug assembly 300 to be connected to a power source, so that the three have an electrical connection relationship. Illustratively, one end of the plug assembly 300 located in the housing 100 has at least one pair of terminals, wherein one pair of terminals is electrically connected to the socket functional module, the socket functional module is further electrically connected to the circuit board 212 of the key switch 200, and the connection point is located on the circuit board 212 and located outside the receiving cavity 231; alternatively, one end of the plug assembly 300 located in the housing 100 has at least two pairs of terminals, one pair of terminals is electrically connected to the socket function module, and the other pair of terminals is electrically connected to the key switch 200.

first, only the lamp cover 220 is exposed on the panel of the attachment 120, and the lamp cover 220 replaces the switch key, and the on-off state of the light emitting device 213 is controlled by pressing the lamp cover 220, so that the light transmission area of the light emitting device 213 can be increased, a good lighting effect is achieved, and the panel structure is simple and beautiful. When the lamp cover 220 is pressed, the light emitting device 213 can change the on-off state to illuminate the area where the socket is located, so that a user can conveniently get up and use the socket;

secondly, since the bracket 230 accommodating the light emitting device 213 is connected to the inner side of the panel, the light emitted from the light emitting device 213 will not be scattered around, but will only be emitted from the direction perpendicular to the panel, thereby effectively preventing light leakage and improving the use experience;

third, the socket is designed to be a structure of a Chinese character pin, and the plug pin assembly 300 is located in the attachment part 120, so that the occupied area of the socket on the power socket can be reduced, other jacks can be avoided, and the space of the power socket can be more effectively utilized.
