Detailed Description

The technical solution of the present application will be described in detail below with reference to the accompanying drawings and the specific embodiments, it should be understood that these embodiments are only for illustrating the present application and not for limiting the scope of the present application, and various modifications of equivalent forms of the present application will fall within the scope of the appended claims after reading the present application.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1-3, an embodiment of the present application includes a receptacle 10 and a plug 20. The receptacle 10 and the plug 20 are used in cooperation. The construction of the socket 10 is substantially the same as that of the prior art socket. The socket 10 includes a socket upper case 101 and a socket lower case 102. The socket upper case 101 and the socket lower case 102 together constitute a housing of the socket 10. The socket upper case 101 may be provided with a jack 103 or the like. Conductive copper sheets, wires, and structures for fixing the conductive copper sheets and wires may be disposed in the socket lower case 102.

Referring to fig. 1, the conductive copper sheet may basically include a negative electrode tab 30 and a positive electrode tab 40. For the three-hole socket 10, a ground pole piece 50 for connecting to ground may also be included. As for the negative electrode tab 30, the same structure as the negative electrode tab in the prior art, that is, the first negative electrode tab 301 disposed opposite thereto is included. The first negative electrode tab 301 is formed with a space capable of accommodating the plug 20, and when the plug 20 is inserted into the space through the insertion hole 103, at least the first negative electrode tab 301 is contacted to conduct electricity. Similarly, the positive electrode sheet 40 also includes a first positive electrode sheet 401, and the structure and arrangement manner thereof are the same as those of the negative electrode sheet 30, and will not be described again. The first negative pole piece 301 is connected to the neutral line 303, and the first positive pole piece 401 is connected to the live line. For the three-hole socket 10, the ground pole piece 50 is connected to ground.

To achieve the safety function of the socket 10, referring to fig. 3, an embodiment of the present application further includes a second positive pole piece 402 and a second negative pole piece 302. The second positive electrode tab 402 is located in the structure of the socket lower case 102 for fixing the conductive copper sheet and the conductive wire, and a space capable of accommodating the plug 20 is formed on the socket lower case 102, which communicates with the first positive electrode tab 401. Referring to fig. 6, for example, the second positive electrode tab 402 may be a rectangular metal sheet located at a position between two tabs of the first positive electrode tab 401. In order to prevent the metal object from coming into contact with the second positive electrode tab 402 after it is inserted into the insertion hole 103, the second positive electrode tab 402 is spaced from the first positive electrode tab 401 by a distance from a space formed to accommodate the plug 20. And, the second positive electrode tab 402 is at least partially not located in the area of the shadow cast by the jack 103 of the socket 10 along the insertion direction, that is, the relative position between the second positive electrode tab 402 and the jack 103 is to ensure that the external metal member will not contact the second positive electrode tab 402 when inserted into the socket 10 through the jack 103.

Referring to fig. 6, a channel 105 is formed in the structure at this distance. Correspondingly, referring to fig. 4 and 5, a metal conductor 201 perpendicular to the insertion direction of the plug 20 is also provided on the mating plug 20, and the metal conductor 201 may extend into the channel 105 and be in contact with the second positive electrode tab 402 for electrical conduction. Alternatively, the metal conductor 201 may be a spring. The metal conductor 201 may be provided on the plug 20 by a screw 202 and a nut 203. The metal spring can be retracted inwards and ejected outwards by means of the cooperation of the screw 202 and the nut 203 or by means of a spring. When the plug 20 is inserted into the socket 10, the metal spring sheet can retract inwards so that the plug 20 can be inserted into the socket 10, and when the plug 20 is inserted into the socket 10, the metal spring sheet springs outwards and stretches into the channel 105 to be in contact with the second positive electrode plate 402 for conducting electricity.

Similarly, the structure of the second negative electrode plate 302 is the same as and symmetrically arranged with the structure of the second positive electrode plate 402, and after understanding the structure and arrangement of the second positive electrode plate 402, those skilled in the art can think about the structure and arrangement of the second negative electrode plate 302, and will not be described again.

When the socket 10 is used, if the safety function of the socket 10, namely, the normal state is not needed, the socket 10 can be assembled, the socket lower shell 102 is installed, the positive electrode pole piece and the negative electrode pole piece are installed at the corresponding positions of the socket lower shell 102, meanwhile, the zero line 303 of the socket 10 is connected with the first negative electrode pole piece 301 and the second negative electrode pole piece 302, the ground wire is connected with the ground wire pole piece 50, meanwhile, the first live wire 403 is connected with the first positive electrode pole piece 401, the socket upper shell 101 and the socket lower shell 102 are locked by screws, and the socket 10 is installed, can be used as a common socket at the moment, and meets the daily electricity consumption requirement.

When the safety function of the socket 10 is used, the socket needs to be matched with the matched plug 20. At this time, the socket lower shell 102 is installed first, the positive and negative electrode plates are installed at the corresponding positions of the socket lower shell 102, meanwhile, the zero line 303 of the socket is connected with the first negative electrode plate 301 and the second negative electrode plate 302, the ground line is connected with the ground line plate 50, meanwhile, the second live wire 404 is installed with the second positive electrode plate 402, and at this time, the first live wire 403 is not connected with the first positive electrode plate 401. Referring to fig. 7, when in use, the two-pin plug 20 or the three-pin plug 20 is inserted into the socket 10, the metal spring sheet on the plug 20 pops up and contacts with the second positive pole piece 402, and at this time, the plug 20 is electrified, so as to meet the electricity requirement of people. When the plug 20 is pulled out, the first positive electrode tab 401 is exposed to the outside, but is not electrified at this time because it is connected to the first live wire 403, and even if it is in contact with metal, there is no risk of electric shock, and safety is achieved. Referring to fig. 6, the energized second positive electrode tab 402 is under the socket upper case 101, and is limited by the limit structure 104 of the socket lower case 102, and even if a metal rod is inserted, it cannot be in contact with the energized second positive electrode tab 402, so that the safety is high.
