In the using process, if a child inserts the plate-shaped structure with the size similar to that of the plug pin into the ground wire jack 3, in the inserting process, after the plate-shaped structure is contacted with the first conducting plate 10, the plate-shaped structure is continuously inserted, so that the limiting bulge 19 is extruded under the transmission action of the connecting rod 25 and is spread to two sides, and one end of the Y-shaped head 17 of the safety door 5 is limited; in this state, if a child continues to hold a conductive object with a size similar to that of the plug pin and insert the conductive object into the live wire and zero wire jacks 3, the safety door 5 is limited and cannot slide, so that the conductive plate is limited and cannot continue to insert after touching the safety door 5; that is, the conductive object held by the child does not contact the corresponding charged first conductive strips 10 in the live and neutral wire jacks 3; the electric shock situation can be prevented when children hold a platy structure with the size similar to that of a plug pin and insert the platy structure into the ground wire jack 3 and continue to insert the conducting strips into the live wire and the zero line; compared with the patent application number of CN201821247525.5, the structure designed by the invention improves the use safety.
According to the invention, the switch button 2 can slide inwards relative to the socket shell 1 by pressing the switch button 2 downwards, in the sliding process, after the switch button 2 is contacted with the pressing plate 13, the switch button 2 is continuously pressed inwards, the pressing plate 13 is extruded by the switch button 2, so that the pressing plate 13 swings around the swinging shaft, the pressing plate 13 swings to drive the pushing plate 12 to move upwards along the first sliding groove 20, the plug 33 inserted into the first conducting strip 10 can be pushed outwards by driving the pushing plate 12 to move outwards relative to the socket shell 4, the plug 33 is pulled out in an auxiliary manner, and the plug 33 is ensured to be pulled out smoothly.
When the plug inserted bars corresponding to the live wire and the zero wire on the plug 33 are inserted into the corresponding sockets 3, the plug inserted bars can firstly contact with the inclined surface of the safety door 5 on the safety door 5, and the safety door 5 is extruded by the inclined surface of the safety door, so that the safety door 5 slides towards one side of the limiting bulge 19; during the insertion process, after the plug inserted rod contacts the adjusting slide block 28, the plug inserted rod is inserted downwards continuously, so that the adjusting slide block 28 slides relative to the safety door 5 and finally slides to the lower side of the safety door 5, and the fifth spring 36 is compressed in the process; after the plug is inserted, under the action of the fifth spring 36, the straight area at the front end of the adjusting slider 28 is tightly pressed on the plug rod, so that the plug 33 is frictionally limited, and the plug reliability is improved.
When a fire disaster occurs, the memory metal 9 is bent and deformed due to the high temperature; the memory metal 9 deforms and pulls the upper end of the first conducting strip 10 fixedly connected with the memory metal to enable the memory metal to swing to one side far away from the inserted plug 33, and the connection between the memory metal and the plug 33 is disconnected; since the insulating plate 27 is installed between the other end of the first conductive plate 10 and the plug pin, and is in a disconnected state, the power is cut off between the plug 33 and the socket at this time; the socket can prevent the plastic in the common socket from burning out to cause short circuit and influence the use of the special socket. And for the fire-fighting plug, the fire-fighting plug can be normally used because the fire-fighting plug is provided with the bolt bulge.
For the special socket used in fire fighting, a plug pin bulge 34 is arranged on a plug pin of a plug 33 matched with the special socket, and a socket shell 1 of the special socket is provided with an insertion notch 23 for the plug pin bulge 34 to insert; the insertion notch 23 does not interfere with the insertion of the normal plug 33; when inserting special plug 33, need at first press shift knob 2, make push pedal 12 shift up, push pedal 12 shifts up and drives ejector pin 8 and shift up, ejector pin 8 shifts up and extrudes limiting plate 6 and move inwards through inclined plane 30 on the limiting plate 6, after limiting plate 6 moves to socket shell 1 inboard completely, insertion breach 23 on the socket shell 1 gives out completely, just can insert special plug 33 this moment, after inserting, loosen shift knob 2, under the effect of first spring 7 and second spring 11, limiting plate 6 resets and moves outward, it is spacing to plug 33 with the protruding 34 cooperation of the bolt on the plug inserted bar, the reliability of pegging graft has been improved.
