The lower parts of the two are communicated (the communication part 107 of the first electrode connecting sheet 105 and the second electrode connecting sheet 101 in fig. 1) to increase the contact area with the electric plug 106, and a vertical clamping socket is formed between the middle upper parts of the two for connecting the electric plug 106, and the thickness of the clamping socket is smaller than that of the insert sheet of the electric plug 106. A movable electrical connection means 104 is fixed to the second electrode connecting pad 105. One end of the movable electrical connection device 104 is connected to the second electrode connecting piece 105, and the other end is close to the fixed electrical connection device 102, and the fixed electrical connection device 102 is fixed on the base of the safety power socket. When the movable electrical connection device 104 is moved toward the fixed electrical connection device 102, it contacts and makes an electrical connection with the fixed electrical connection device 102.

The first electrode connecting piece 101 and the second electrode connecting piece 105 are not electrified, and any electric shock and arc cannot be generated under the condition that the first electrode connecting piece 101 and the second electrode connecting piece 105 are touched.
When the electrical plug 106 is gradually inserted into the jack, the second electrode connecting piece 105 is gradually pressed by the electrical plug 106 and gradually moves towards the outside of the jack, so as to drive the movable electrical connection device 104 to gradually move outwards and approach the fixed electrical connection device 102, and at this time, the movable electrical connection device 104 and the fixed electrical connection device 102 are not in contact, so that the electrical plug 106 and the fixed electrical connection device 102 are in a disconnected state.

At this point, the electrical plug 106 is in an open state with the fixed electrical connection 102. The first electrode connecting piece 101 and the second electrode connecting piece 105 are not electrified, and any electric shock and arc cannot be generated under the condition that the first electrode connecting piece 101 and the second electrode connecting piece 105 are touched.
When the electric plug 106 is completely inserted into the jack, the electric plug 106 is tightly connected with the first electrode connecting piece 101 and the second electrode connecting piece 105, the second electrode connecting piece 105 moves rightwards due to the squeezing action of the electric plug 106, the spring 304 is further compressed, the acting force to the right is larger than the sum of the attraction force between the third magnet 306 and the second magnet 305 and the elastic force of the spring 304, the third magnet 306 is separated from the second magnet 305, the first contact piece 201 is in tight contact with the second contact piece 202 instantly, meanwhile, the first magnet 302 and the third iron block 306 are attracted together, and the spring 304 is further compressed.
