When the ground pin of the three-pin plug is inserted into the plug connecting piece 1312 and abuts against the connecting plate 13122, the ground pin pushes the sliding connecting plate 13 to move downwards, when the sliding connecting plate 13 moves to the lowest end of the stroke, the ground connecting piece 135 is connected with the ground conducting block 144, meanwhile, the two elastic connecting pieces 136 are respectively connected with the two corresponding pin conducting blocks 145 and the connecting conducting block 146, the plug connecting piece 1312 is connected with the ground connecting ring 121 through the conducting pieces 147, the two pin connecting pieces 141 are respectively connected with the neutral connecting ring 122 and the live connecting ring 123, and at the moment, the three-pin plug is electrified; when the three-pin plug is pulled out, each pin moves upwards, the ground pin drives the sliding connection disc 13 to move upwards due to the friction force of the pin clamping piece 13121, the spring 143 resets and pushes the sliding connection disc 13 to move upwards, when the sliding connection disc 13 moves to the uppermost end of the stroke, the ground connection piece 135 is separated from the ground conductive block 144, and simultaneously, each elastic connection piece 136 is separated from the corresponding pin conductive block 145 and the corresponding connection conductive block 146, so that the three-pin plug is powered off.

The sections of the seat cover 11, the electrode mounting seat 12, the sliding connecting disk 13 and the conductive cylinder 14 are all circular; the positioning post 142 is connected to the positioning ring 134, and the limiting post 132 is connected to the limiting ring 114, so that the seat cover 11, the electrode mounting seat 12, and the sliding connecting disk 13 can rotate synchronously.

The socket shell 2 is provided with a power transmission line 4, and a first connecting line 31, a second connecting line 32 and a third connecting line 33 which are respectively connected with a ground wire, a zero wire and a live wire of the power transmission line 4; the first connection line 31 is connected to the ground connection ring 121; the second connecting wire 32 is connected with the neutral connecting ring 122; the third connection line 33 is connected to the live connection ring 123. The positions and structures of the ground wire connecting ring 121, the zero wire connecting ring 122 and the live wire connecting ring 123 are as follows: the ground wire connecting ring 121, the zero wire connecting ring 122 and the live wire connecting ring 123 are sequentially and fixedly connected to the inner wall of the electrode mounting base 12 from bottom to top; the lower part of the outer wall of the electrode mounting base 12 is fixedly connected with a ground wire connector 124 electrically connected with the ground wire connecting ring 121, the middle part of the outer wall is fixedly connected with a zero wire connector 125 electrically connected with the zero wire connecting ring 122, and the upper part of the outer wall is fixedly connected with a live wire connector 126 electrically connected with the live wire connecting ring 123; the ground wire connector 124 is electrically connected to the first connecting wire 31; the zero line connector 125 is electrically connected with the second connecting line 32; the fire wire connector 126 is electrically connected with the third connecting wire 33; through the structure, the ground wire connecting ring 121 is connected with a ground wire, the zero line connecting ring 122 is connected with a zero line, and the live wire connecting ring 123 is connected with a live wire.

The lower end of the seat cover 11 is fixedly connected with a dust strip 113 at the position of the jack 111; the dust-proof strip 113 is two half bodies symmetrically arranged at two sides of the insertion hole 111, and when the pin is inserted into the insertion hole 111, the two half bodies of the dust-proof strip 113 are separated towards two sides of the pin and are abutted against the pin, so that dust can be prevented from entering the electrode mounting base 12; furthermore, when the three pins of the three-pin plug are inserted into the insertion holes 111, the dust-proof strips 113 are abutted against the pins, and because the spring 143 contracts to push the plug outwards, friction force is generated between the pins and the dust-proof strips 113, and the resultant force of the friction force is greater than the elastic force generated by the spring 143 after contraction, so that the three-pin plug can be stably inserted into the socket without falling.

The ground wire connecting piece 135 and the two elastic connecting pieces 136 have elasticity, so that the ground wire connecting piece 135 and the two elastic connecting pieces 136 are prevented from being irreversibly deformed to influence the connecting effect when the sliding connecting disc 13 moves to the lowest end of the stroke.

The seat cover 11, the sliding plate 131, the conductive cylinder 14, and the electrode mounting seat 12 are made of insulating materials. Further, when the three-pin plug is completely inserted into the seat cover 11, that is, the three-pin plug is just abutted against the upper end surface of the seat cover 11 or has a gap, the gap is 0-2mm, the ground wire connecting piece 135 is just connected with the ground wire conductive block 144, the elastic connecting piece 136 is just connected with the corresponding pin conductive block 145 and the connecting conductive block 146 respectively, and at this time, the three-pin plug can be powered on; the three-prong plug is not energized when not fully inserted into the receptacle and does not get electrocuted when the user's fingers contact the prongs of the three-prong plug.

In an initial state, the spring 143 enables the sliding connection disc 13 to be positioned at the uppermost end of the stroke, the ground wire connection piece 135 is separated from the ground wire conductive block 144, and each elastic connection piece 136 is separated from the corresponding pin conductive block 145 and the connection conductive block 146 respectively, so that the ground wire connection ring 121, the zero wire connection ring 122 and the live wire connection ring 123 are not connected with each pin of the three-pin plug; before the three-pin plug is inserted, the power-on assembly 1 is adjusted to enable the socket to be matched with the angle of the three-pin plug, and therefore the three-pin plug can be inserted into the socket.

When the power is on, the three-pin plug is inserted into the power-on assembly 1, so that the ground pin is inserted into the plug connecting piece 1312, and the zero-wire pin and the live pin are respectively connected with the corresponding pin connecting pieces 141; the lower end of the ground pin is pressed against the upper end of the connecting plate 13122 in the process of inserting the three-pin plug, the ground connecting plate 135 is connected with the ground conductive block 144, meanwhile, each elastic connecting plate 136 is respectively connected with the corresponding pin conductive block 145 and the connecting conductive block 146, at the moment, the spring 143 is compressed, and the friction force between each pin of the three-pin plug and the jack 111 is larger than the elastic force of the spring 143, so that the three-pin plug keeps the electrified state.

When the three-pin plug is pulled out, the plug connecting piece 1312 clamps the ground pin and the spring 143 resets, the sliding connecting disc 13 is driven to move upwards when the three-pin plug is pulled out, so that the ground connecting piece 135 is separated from the ground conductive block 144, and each elastic connecting piece 136 is separated from the corresponding pin conductive block 145 and the connecting conductive block 146 respectively to realize the power failure of the three-pin plug; continued upward pulling of the three-prong plug separates the ground pin from the plug connector pad 1312 and the neutral and live pins from the corresponding pin connectors 141, respectively.

The arrangement of each electrifying component 1 and the electrode mounting base 12 enables the three-pin plug to rotate 360 degrees when being inserted into the socket, so that the angle can be automatically adjusted when the wire is not long enough or the plug is difficult to be inserted into the socket at a fixed angle; by separating the ground wire connecting sheet 135 from the ground wire conductive block 144 and separating each elastic connecting sheet 136 from the corresponding pin conductive block 145 and the connecting conductive block 146 respectively, the socket can not conduct electricity with the power transmission line 4 when a conductor is inserted into the jack 111 in the power-on state of the socket, thereby avoiding the occurrence of electric shock accidents; the lower end of the ground pin of the three-pin plug is abutted against the upper end of the connecting plate 13122 to drive the sliding connecting plate 13 to move downwards, the ground connecting plate 135 is connected with the ground conductive block 144, and meanwhile, each elastic connecting plate 136 is respectively connected with the corresponding pin conductive block 145 and the connecting conductive block 146 to realize the electrification of the three-pin plug; the plug connecting piece 1312 has elasticity, so that the three-pin plug can be smoothly conducted when inserted and can drive the sliding connecting disc 13 to move upwards through friction force when pulled out; the lower end of the seat cover 11 is provided with a limit ring 114 which can limit the stroke of the sliding connection disc 13, and the three-pin plug can be smoothly pulled out after the lower end is abutted against the sliding plate 131; the lower end of the seat cover 11 is fixedly connected with a dust-proof strip 113 at the position of the insertion hole 111, and has a dust-proof function.
