As further preferred in the present invention: the insulating elastic sleeve is sealed with the blocking plate before the live wire contact contacts the live wire reset contact ring; when the live wire contact contacts the live wire reset contact ring, after the external force of pressing disappears, the insulating elastic sleeve can release redundant elasticity to extrude the live wire reset contact ring, so that the live wire reset contact ring is contacted with the extension contact boss; at this time, the live line circuit is turned on.
As further preferred in the present invention: the outer height of the circular ring of the ground wire conductive sleeve ring is higher than that of the zero line conductive sleeve ring; thus, when the neutral contact and the neutral conductive collar are disengaged, the ground conductive collar remains in contact with the ground contact; the contact range of the ground wire conductive sleeve ring and the ground wire contact is larger than that of the live wire contact and the live wire reset contact ring; thus, when the hot contact and the hot return contact ring are removed from contact, the ground conductive collar remains in contact with the ground contact.

Compared with the prior art, after the technical scheme is adopted, the method has the following beneficial effects:
firstly, the quick matching is realized, and the device can be used by inserting without alignment; no distinction is made between ground, live and neutral.
Secondly, the waterproof and electric shock prevention performance is high; as long as water does not permeate into the anti-electric shock assembly, water permeates into the circuit cavity, and the barrel insert device is matched with the anti-electric shock assembly, so that electric shock cannot be caused.
Thirdly, after the cylinder insert and the electric shock prevention assembly are successfully matched, even if the whole socket is soaked in water, as long as the tightness of the electric shock prevention assembly and the direct air tightness of the electric shock prevention assembly and the fixed bottom column are well made, and water does not enter the circuit cavity, an independent air tight space can be formed between the cylinder insert and the blocking plate, and water flow does not need to be worried about; can still ensure the normal use of the utility model.

As preferred in the present invention: the plugboard main body 1 is also provided with a circuit closing plate 14; the circuit closure plate 14 is used to enclose the circuit cavity 12.
In order to realize high-grade waterproof and electric shock prevention, the length of the insulating elastic sleeve 23 is longer than the sum of the distance from the electric shock prevention assembly 4 to the barrier plate 10, the extrusion resilience distance of the live wire resetting contact ring 47 and the error distance; ensuring that the insulating elastic sleeve 23 is still tightly fitted with the blocking plate 10 before the live wire contact 211 of the clamping part 21 is completely separated from the live wire reset contact ring 47; so that the liquid and gas inside and outside the insulating elastic sleeve 23 are blocked by the insulating elastic sleeve 23 and cannot circulate; when the live wire contact 211 is completely separated from the live wire reset contact ring 47, the moving distance of the continuous movement of the live wire contact needs to be greater than the error distance, and then the insulating elastic sleeve 23 is separated from the blocking plate 10, so that the liquid inside and outside the insulating elastic sleeve 23 circulates again; the insulating elastic sleeve 23 is already sealed with the blocking plate 10 before the live wire contact 211 contacts the live wire reset contact ring 47; after the live wire contact 211 contacts the live wire reset contact ring 47, and the external pressing force disappears, the insulating elastic sleeve 23 releases the excessive elastic force to press the live wire reset contact ring 47, so that the live wire reset contact ring 47 contacts with the extension contact boss 442; at this time, the live line circuit is turned on.
In order to further increase the safety and make the ground wire break away from the ground wire finally, so even if the fire wire breaks away from the accident, the ground wire can also provide the safety guarantee, the outer height of the ring of the ground wire conductive sleeve ring 43 is higher than that of the zero line conductive sleeve ring 41; thus, when neutral contact 213 and neutral conductive collar 41 are disengaged, ground conductive collar 43 remains in contact with ground contact 212; the contact range between the ground conductive collar 43 and the ground contact 212 is larger than the contact range between the live contact 211 and the live return contact 47; thus, when the hot contact 211 and the hot return contact ring 47 are removed from contact, the ground conductive collar 43 remains in contact with the ground contact 212.
In order to further ensure that the safety can be better guaranteed even if the cartridge and the barrier plate are invaded by water after being matched, the sealing performance between the cartridge and the barrier plate is important, so the following scheme is adopted: the bottom of the insulating elastic sleeve 23 is provided with a flexible, waterproof and durable isolating layer 231; an adjusting spring 232 is arranged in the isolating layer 231; the bottom of the isolation layer 231 is further provided with a bottom annular suction cup 233; the adjusting spring 232 is specifically positioned between the insulating elastic sleeve 23 and the bottom annular sucking disc 233; the bottom ring chuck 233 has already sealed with the baffle 10 before the hot contact 211 contacts the hot reset contact ring 47; when the live wire contact 211 contacts the live wire reset contact ring 47, and the external pressing force disappears, the adjusting spring 232 releases the excessive elastic force to press the insulating elastic sleeve 23, so that the live wire contact 211 together with the insulating elastic sleeve presses the live wire reset contact ring 47, and the live wire reset contact ring 47 is in contact with the extension contact boss 442; at this time, the live line circuit is turned on.
The using method comprises the following steps:
when in use: the said cartridge 2 is connected with the electric shock preventing suit 4, make its zero line contact 213, ground wire contact 212 and live wire contact 211 cooperate with conductive lantern ring 41 of zero line, conductive lantern ring 43 of ground wire and live wire of live wire to reset the contact ring 47 separately, meanwhile, produce the elastic force of contradicting between insulating elastic sleeve 23 and baffle 10, the said insulating elastic sleeve 23 brings the grip part 21 to move back, thus the live wire contact 211 begins to squeeze the live wire and resets the contact ring 47, make it overcome the elasticity of the internal reset spring 46, produce the contact with lengthening the contact boss 422, thus is conductive; in this state, the elastic force of the interference between the insulating elastic sleeve 23 and the blocking plate 10 is already reduced, and the rest force is still greater than the elastic force of the return spring 46, but the clamping portion 21 cannot be separated from the electric shock preventing sleeve set 4; a balance of force is formed, and normal electrification is ensured;
when not in use: the cartridge 2 is pulled out continuously to break the balance of the original force, so that the clamping portion 21 is separated from the anti-electric shock sleeve set 4.
