(18) In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below Obviously, the described embodiments are only some embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those skilled in the art without paying creative labor shall fall within the protection scope of the present invention.

(19) Hereinafter, embodiments will be described with reference to the drawings. In addition, the embodiments shown below do not limit the content of the present invention described in the claims in any way. In addition, all the contents of the configuration shown in the following embodiments are not limited to what is necessary as a solution to the present invention described in the claims.

(20) Referring to FIGS. 1 to 13, the present invention comprises a housing provided with a first socket 21, wherein the housing is provided with: a conductive part 5, wherein the conductive part 5 is connected with a power cord connecting piece 6; a conductive piece 4, wherein the conductive piece 4 is provided with a clamping portion 42, and the clamping portion 42 is located directly below the first socket 21 for clamping the male tab inserted into the plug of the first socket 21. The conductive piece 4 is further provided with a first contact portion 41 extending from the clamping portion 42, the conductive part 5 is provided with a second contact portion 51, a gap is provided between the first contact portion 41 and the second contact portion 51, the first contact portion 41 or the second contact portion 51 is provided in an elastic structure, a rotating part 7 made of insulating material is rotatably provided in the housing, the rotating part 7 is provided with a first protrusion 72 protruding in the direction of the edge of the first socket 21, and the first protrusion 72 protrudes from the edge of the first socket 21 in a direction perpendicular to the depth of the first socket 21 and is located below the first socket 21. When the male tab is inserted into the first socket 21, the edge of the male tab touches the first protrusion 72 and pushes the male tab pushes the rotating part 7 to rotate and thereby pushes one of the first contact portion 41 and the second contact portion 51 to elastically deform so as to approach and contact with the other of the first contact portion 41 and the second contact portion 51, the conductive piece is charged and the circuit is turned on at this time; when the male tab is pulled out of the first socket 21, the first contact portion 41 or the second contact portion 51 that has undergone elastic deformation recovers from the elastic deformation, the first contact portion 41 is separated from the second contact portion 51, and the conductive piece 4 is not charged at this time. In such a way, only when the socket plastic hardware structure is used, that is, when a plug of another electrical appliance is inserted into the first socket 21, the conductive piece 4 is charged and the circuit is turned on. When the first socket 21 is in an idle state, the conductive piece 4 is not charged. When water splashes into the first socket 21, a short circuit will not occur; or when a finger of child touches the first socket 21 or a non-standard conductor is inserted into the first socket 21 by mistake, there will be no electric shock.

(21) The rotating part 7 is further provided with a second protrusion 73 and a rotating shaft portion 71. As shown in FIG. 5, the rotating shaft portion 71 can be configured as a cylindrical shape, and a cylindrical groove matching the rotating shaft portion 71 can be provided in the housing. The rotating part 7 is rotatably provided in the housing in such a way that the rotating shaft portion 71 is matched with the cylindrical groove. The first protrusion 72 and the second protrusion 73 may both be configured as arc-shaped protrusions. As shown in FIG. 3, the second protrusion 73 protrudes in the direction of the first contact portion 41 or the second contact portion 51. It should be noted that only a small part of the first protrusion 72 is exposed at the edge below the first socket 21. The non-standard conductor can drive the conductive piece 4 to be in contact with the conductive part 5 to be charged and thus get an electric shock only when the non-standard conductor is inserted into, is in contact with and pushes the first protrusion 72 at the edge. However, the conductive piece 4 or the conductive part 5 is in an elastic structure, and the first protrusion 72 can be provided in an arc shape. When the non-standard conductor pushes the first protrusion 72 to rotate, under the elastic reaction force, the conductive piece 4 or the conductive part 5 will push the non-standard conductor to move in the direction away from the first protrusion 72. Since the first protrusion 72 is arc-shaped, the non-standard conductor will slide or move by mistake with respect to the first protrusion 72, so that it is not easy to push the rotating part 7 to rotate, thereby charging the conductive piece 4, which may result in a risk of electric shock. Only when the male tab has the same size as that of the first socket 21, the male tab is clamped by the clamping portion 42, and can smoothly push the rotating part 7 to rotate so that the circuit is turned on when being inserted stably downwards. The distance between the first contact portion 41 and the second contact portion 51 may be provided such that the first contact portion 41 and the second contact portion 51 are just in contact with each other when the male tab is inserted to the bottom end, which further reduces the possibility of electric shock.

(22) As shown in FIG. 8, the second contact portion 51 may be provided as a horizontally provided horizontal plate 511 and a vertically provided second contact plate 512 which are connected vertically to each other. As shown in FIG. 7, the first contact portion 41 is provided such that a vertically provided vertical plate 411 and a first contact plate 412 are vertically connected to each other. As shown in FIG. 3, a gap is provided between the first contact plate 412 and the second contact plate 512, and the second contact plate 512 is located on one side of the rotating part 7. The horizontal plate 511 is located under the vertical plate 411 and the first contact plate 412 and is not in contact with each other. When the male tab is inserted into the first socket 21, the male tab pushes the first protrusion 72 to drive the rotating part 7 to rotate, and the second protrusion 73 pushes the second contact plate 512 to bend toward and contact the first contact plate 412 so that the conductive piece 4 is charged. In such a way, the structure is simple and less space is occupied, so that the volume of the socket plastic hardware structure device is reduced.

(23) The first contact plate 412 and the second contact plate 512 are both provided with conductive contacts 8 protruding toward each other at corresponding positions. As shown in FIG. 3, a gap is provided between the two conductive contacts 8. The conductive contact 8 is added, so that it is easier to conduct the conductive part 5 and the conductive piece 4.

As shown in FIG. 9, the first protrusion 72 protrudes from the edge of the second socket 311 in the direction perpendicular to the depth of the second socket 311 and is located below the second socket 311. As shown in FIG. 6, the fixing member 32 is provided with a second semi-cylindrical groove 321 matching the rotating shaft portion 71, the rotating shaft portion 71 is rotatably provided in a cylindrical groove formed by buckling the first semi-cylindrical groove 312 and the second semi-cylindrical groove 321, and the fixing member 32 is further provided with a neck for fixing the conductive piece 4 and the conductive part 5. The rotary connection formed by the cylindrical groove formed by buckling the rotating shaft portion 71, the first semi-cylindrical groove 312, and the second semi-cylindrical groove 321 can save space on the one hand, and facilitate installation on the other hand.
