This design can only make the inside slider I8 of single electricity sleeve 7 of inserting move when child inserts the live wire socket with the metal conductive object such as finger or iron nail, and the inside half distance that can only make slider II 13 move in sleeve II 12 is removed in the removal of single slider I8, can not make the circuit switch-on to reduce the emergence of electric shock accident.

Please refer to fig. 2, wherein, the plug-in sleeve 7 and the sleeve ii 12 are insulators to increase the safety, one side of the bottom of the left plug-in sleeve 7 is provided with a conducting strip ii 11, the conducting strip ii 11 can contact with the sliding block i 8 when the sliding block i 8 contacts with the bottom of the plug-in sleeve 7, so as to further increase the safety, the other end of the conducting strip ii 11 is arranged at the maximum distance of the movement of the sliding block ii 13 on the side of the sleeve ii 12, the sliding block ii 13 can always contact with the conducting strip ii 11 when sliding inside the sleeve ii 12, one side of the bottom of the sliding block i 8 on the right side is provided with a conducting strip i 9, and the conducting strip i 9 is connected with the zero line connector 6.

Referring to fig. 2, a conducting plate iii 14 is disposed directly above the fire wire connector 5, the conducting plate iii 14 is mounted at the bottom of a sliding block ii 13, when the sliding block ii 13 moves to the maximum distance, the fire wire connector 5 and the conducting plate iii 14 can contact each other, so that the sliding block i 8 is electrified, the conducting plate iii 14 is made of a solution metal, when an electrical appliance is short-circuited, the conducting plate iii 14 generates heat due to an excessive current, a memory metal spring 15 is disposed around the conducting plate iii 14, the memory metal spring 15 can expand at a high temperature, a deformation critical temperature of the memory metal spring 15 is sixty degrees celsius, one end of the memory metal spring 15 is fixedly mounted at the bottom end inside the sleeve ii 12, a height of the memory metal spring 15 at normal temperature is equal to a distance from the bottom surface of the sliding block ii 13 to an opposite surface of the sleeve ii 12 when the sliding block ii 13 moves to the maximum distance, when the conducting plate iii 14 contacts the fire wire connector 5, the top end of the memory metal spring 15 just contacts the bottom surface of the sliding block II 13. When short circuit in the electrical apparatus, conducting strip III 14 can generate heat rapidly, lead to the temperature around conducting strip III 14 to rise, when the temperature reaches the critical point of memory metal spring 15 deformation, memory metal spring 15 can take place deformation, promote slider II 13 to make it upwards slide then, conducting strip III 14 and memory metal spring 15 disconnection at this moment, with the outage of electrical apparatus, the inner chamber volume reduction pressure increase that slider II 13's upper surface and sleeve II 12 are constituteed, the pressure that suddenly increases will enter into the inside of inserting electric sleeve 7 through pipe 10, thereby make slider I8 slide in the inside of inserting electric sleeve 7, make plug 2 and the contact surface separation of shell 1, be convenient for the resident to confirm the electrical apparatus of short circuit.

Wherein, the inner chamber of pipe 10 intercommunication all fills liquid, can make II 13 of slider downstream when 3 extrusion sliders I8 of bolt to liquid pressure's conduction is more stable for atmospheric pressure, and this liquid is the pure water, has insulating effect.

The contact surface of the live wire connector 5 and the conducting strip III 14 is arc-shaped and elastic, so that the contact can be more compact, the rigid force during the contact can be reduced, and the service life of the socket can be prolonged.

The use method (working principle) of the invention is as follows:

during the outage, 2 backs at extraction plug, because metal card 4 and 3 in close contact with of bolt, metal card 4 can outwards remove simultaneously at the in-process that 3 extracts of bolt, then drive I8 rebound of slider, make II 13 of slider reset, thereby make I8 of slider uncharged, just can insert the live wire socket with the metal conducting object of finger or iron nail class at child in-process, only can make the inside I8 of slider of single plug-in sleeve 7 remove, single I8 of slider removes and can only make II 13 of slider half the distance in the inside removal of sleeve II 12, can not make the circuit switch-on, thereby reduce the emergence of electric shock accident. When the internal short circuit of an electrical appliance, the conducting plate III 14 can rapidly generate heat to cause the temperature around the conducting plate III 14 to rise, when the temperature reaches the critical point of the deformation of the memory metal spring 15, the memory metal spring 15 can deform to further push the sliding block II 13 to upwards slide, at the moment, the conducting plate III 14 is disconnected with the memory metal spring 15, so that the electrical appliance is powered off, the volume of an inner cavity formed by the upper surface of the sliding block II 13 and the sleeve II 12 is reduced, the pressure intensity is increased, the suddenly increased pressure intensity enters the inside of the plug sleeve 7 through the guide pipe 10, the sliding block I8 slides in the plug sleeve 7, the contact surface of the plug 2 and the shell 1 is separated, when the temperature around the memory metal spring 15 is recovered to the normal temperature, the memory metal spring 15 can contract to change to the normal temperature state, and the plug can be normally used.
