Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The safety socket provided by the embodiment of the present application is described in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of a safety socket according to an exemplary embodiment of the present application. And with reference to fig. 4 and 5, the safety receptacle comprises: the socket comprises a socket body and a controller, wherein the controller is arranged in the socket body, namely in a shell of the socket. In the first state, the moving end 42 of the controller is connected to the power supply inlet terminal 43 to connect the power supply, and in the second state, the moving end 42 of the controller is disconnected from the power supply inlet terminal 43 to disconnect the power supply. The first state may be understood as a specific state of the controller, e.g. after insertion of a plug into a socket and bringing the controller to this specific state. The second state may be understood as a state other than the first state, and the second state may be a state of the controller when the socket is not inserted with the plug, or a state in which a foreign substance is inserted. Therefore, the controller is arranged in the socket and can be communicated with the power supply only when the controller is in the first state, so that the situation that the socket leaks electricity due to the insertion of foreign matters and the like to cause casualties can be avoided.

In one implementation, as shown in fig. 2 and 3, the controller includes a rotating shaft 21 and a fixing ring 22 surrounding the rotating shaft 21, and the rotating shaft 21 is provided with an insertion hole therein along an axial direction. The rotary shaft 21 is rotatable in the fixed ring 22. For example, when a specific plug is inserted into the jack in the rotating shaft 21, the user can rotate the rotating shaft 21 by rotating the plug, so that the controller is in the first state, and the moving end 42 of the controller is connected to the power supply inlet end 43 to connect the power supply. The axial direction of the rotating shaft 21 is the thickness direction of the socket body. In the whole rotation process, the movable end and the power supply incoming line end are connected only when the controller is in the first state, and the rest of the movable end and the power supply incoming line end are in the disconnected state.

Further, the controller further comprises a telescopic assembly, the telescopic assembly is arranged in a hole 24 perpendicular to the axis of the rotating shaft 21, a concave-convex structure is formed in the jack, and the hole 24 is formed in the fixing ring 22 and the rotating shaft 21. The retraction assembly is movable within the bore 24 under external or self-acting forces. In the case where the safety receptacle is not inserted with a plug or a foreign object, i.e., in an initial state, the hole 24 penetrates through the fixing ring 22 and the rotating shaft 21, like a communicating passage. Wherein the initial state is one of the second states. Since the hole 24 is perpendicular to the axis of the rotating shaft 21, the part of the telescopic assembly extending out of the hole 24 forms a concave-convex structure in the jack.

Specifically, the telescopic assembly includes a top bar and an elastic structure 233, the top bar includes a first top bar 231 and a second top bar 232, one end of the elastic structure 233 is fixed in the hole 24, and specifically, one end of the elastic structure 233 is fixed in the hole 24 of the fixing ring 22. The other end of the elastic structure 233 is fixedly connected to one end of the second push rod 232, and the first push rod 231 can move in the hole 24 under the action of the other end of the second push rod 232 or the action of an external force. There is no connection between the first and second lift pins 231 and 232. Alternatively, the resilient structure 233 may be a spring.

When the elastic structure 233 is in an original state, that is, in the initial state, the elastic structure 233 has no inward contracting force nor outward pushing force, the second push rod 232 is simultaneously located in the rotating shaft 21 and the hole 24 of the fixing ring 22, and the rotating shaft 21 cannot rotate because the second push rod 232 is transversely located in the gap between the rotating shaft 21 and the fixing ring 22, so that the controller cannot reach the first state, and cannot be connected to a power supply. In addition, even if a foreign object is inserted into the insertion hole, the foreign object may push the first push rod 231, the first push rod 231 pushes the second push rod 232, and the elastic structure 233 contracts inward, but as long as the push rod is transverse to the gap between the rotating shaft 21 and the fixing ring 22, the rotating shaft 21 cannot rotate, the controller cannot reach the first state, and the moving end 42 of the controller cannot be connected to the power supply inlet end 43 and cannot be connected to a power supply. Therefore, the phenomenon that the socket leaks electricity due to the fact that foreign matters are inserted into the socket and casualties are caused can be avoided.

In practical use, when a specific key is used to be inserted into the insertion hole of the safety socket, under the pushing force of the specific key, the elastic structure 233 is in a compressed state, the first ejector rod 231 is located in the hole of the rotating shaft 21, the second ejector rod 232 is located in the hole of the fixing ring 22, no ejector rod is transverse to the gap between the rotating shaft 21 and the fixing ring 22, and at this time, when a user rotates the specific plug, the rotating shaft 21 can be driven to rotate. When the rotating shaft 21 rotates to the preset position, the controller is in the first state, the moving end 42 of the controller is connected with the power supply inlet end 43, and the plug is connected with the power supply. The preset position is realized by the first limit portion, that is, the rotating shaft 21 reaches the first state when being limited by the first limit portion and cannot rotate.

In this embodiment, the rotating shaft can be rotated only when a specific plug is inserted into the safety socket jack, and the plug can be connected to the power supply when the rotating shaft is rotated to a preset position, that is, when the rotating shaft is in the first state. Therefore, the problem that the socket is damaged by casualties due to electric leakage caused by inserting foreign matters and the like can be avoided.

The flexible subassembly is one at least, and when the flexible subassembly was a plurality of, only when the ejector pin of every group flexible subassembly all pushed to first ejector pin 231 is in the downthehole of rotation axis 21, second ejector pin 232 is in gu fixed ring 22's downthehole, no ejector pin is violently when rotation axis 21 with gu fixed ring 22's the condition in the gap, rotation axis 21 can go to reach first state. Obviously, the possibility that foreign matters are inserted into the socket to be connected with the power supply is further reduced, and therefore the safety of the safety socket is improved.

Fig. 4 and 5 are schematic structural diagrams of a safety socket provided in an embodiment of the present application. In one implementation, the moving end 42 is disposed in the insertion hole 41 and extends through an outer wall of the rotating shaft 21. When the rotating shaft 21 rotates, the moving end 42 is rotated together. When the plug is inserted into the insertion hole 41, the plug contacts the moving end 42, and the moving end 42 penetrating the outer wall portion of the rotary shaft 21 is communicated with the power supply inlet terminal 43 in the first state, so that the plug is communicated with the power supply. Optionally, the power supply inlet terminal 43 includes a live inlet terminal and/or a neutral inlet terminal. Optionally, the moving end 42 is disposed at the bottom of the receptacle 41.

The jacks comprise a live wire jack, a zero line jack and a ground wire jack. A moving end 42 is provided in at least one of the live and neutral jacks 41. When a movable end 42 is arranged in the live wire jack, in a first state, the movable end 42 is communicated with the live wire inlet end; when a moving end 42 is arranged in the zero line jack, in a first state, the moving end 42 is communicated with the zero line incoming end; when the moving end 42 is provided in both the live wire jack and the neutral wire jack, as shown in fig. 6 and 7, the moving end 42 in the live wire jack is communicated with the live wire inlet end, and the moving end 42 in the neutral wire jack is communicated with the neutral wire inlet end. For the jack 41 without the moving end 42, the jack 41 is directly connected to the power supply incoming line. In the rotating process of the rotating shaft, the moving end in the live wire jack cannot be communicated with the zero line inlet end, and the moving end in the zero line jack cannot be communicated with the live wire inlet end.

Through setting up removal end 42 and power supply inlet wire end 43 and being in the intercommunication under the first state at the controller, rather than all jacks all lug connection power supply inlet wire to can realize only under specific condition, can only communicate the power, avoid the socket because of inserting reasons such as foreign matter and lead to the electric leakage, cause the casualties.

When a user needs to pull out a specific plug, the rotating shaft 21 is rotated in the opposite direction to return to the initial state, the initial state is realized through the second limiting part, namely, when the rotating shaft 21 is limited by the second limiting part and cannot rotate, the initial state is reached, and the plug can be pulled out. Therefore, even if the safety socket is used, the electric leakage of the socket caused by inserting foreign matters and the like is avoided through recovering the initial state, and casualties are caused.

The present application further provides a plug, which is used with the safety socket described above, as shown in fig. 8, the plug includes a plug body 81 and an insert 82, and the insert 82 includes a concave-convex structure. Wherein the controller is placed in the first state by rotating the plug when the insert 82 is inserted into the safety receptacle.

Specifically, when the plug is inserted into the safety socket, since the concave-convex structure on the plug 82 is matched with the concave-convex structure in the insertion hole 41 of the safety socket, at this time, the elastic structure 233 is in a compressed state, the first push rod 231 is in the hole of the rotating shaft 21, the second push rod 232 is in the hole of the fixing ring 22, and no push rod traverses the gap between the rotating shaft 21 and the fixing ring 22, at this time, when the plug is rotated by a user, the rotating shaft 21 can be driven to rotate. When the rotating shaft 21 rotates to the preset position, the controller is in the first state, the moving end 42 of the controller is connected with the power supply inlet end 43, and the plug is connected with the power supply.

The present application also provides a safety receptacle plug assembly comprising a safety receptacle as described above and a plug as described above. To avoid repetition, the specific structure of the safety receptacle and plug will not be described in detail herein.

The above description is only an example of the present application and is not intended to limit the present application. Various modifications and changes may occur to those skilled in the art.
