An electrode be electrically connected, the another output conductive plate 22 of thermoelectric generation film 18 offsets, conductive plate 22 using conducting wire with
Another electrode of electromagnet 17 is electrically connected, and the inner wall of circular hole is fixed with multiple nylon ropes 21, each nylon rope 21 with circle
Column 20 is glued fixed；
The side wall that shell 1 and conductive sheet 2 are slidably connected is provided with fixed link 10, slidably connects wedge shape in fixed link 10
Block 11, the one end of wedge block 11 far from plate 6 are rotatably connected to rotating bar 12 using pin shaft, and rotating bar 12 is far from wedge block 11
One end is rotatably connected to the first sliding sleeve 14 using pin shaft, and 14 sliding sleeve of the first sliding sleeve is connected to the first traveller 13, the first traveller 13 with
The side wall of shell 1 is fixedly connected, and the first sliding sleeve 14 is internally provided with second spring 15, and the both ends of second spring 15 are respectively with first

The inner wall gluing of two sliding sleeves 24 is fixed, and the second traveller 25 is fixed with steel ball 26 far from one end gluing of the second sliding sleeve 24.
The case where shell 1, connecting plate 3 are made using isolation material, user are avoided to get an electric shock, described first
Spring 7 and second spring 15 are compressed spring, and the third spring 27 is extension spring, guarantee the normal operation of each section, institute
It states square block 9 and second baffle 16 shifts to install, so that second baffle 16 does not produce during the motion with 13 part of the first traveller
The case where raw interference.
In the present invention, the metal clips in socket is when with the conductive sheet 2 of plug because of poor contact, conductive sheet 2 and metal
The resistance increase of the junction of elastic slice causes obviously to generate heat, and heat conducting bar 23 is contacted with conductive sheet 2 can make thermoelectric generation film 18 vertical
The heat generated on conductive sheet 2 is experienced, the other end of 18 sensing chip of thermoelectric generation film is normal room temperature, so conductive sheet 2
Adstante febre can make thermoelectric generation film 18 generate electricity immediately, through conducting wire and the conduction of charged plates 22 to electromagnet 17, it be made to generate magnetic field pair
Steel ball 26 generates certain magnetic force, drives steel ball 26 and the second traveller 25 to drawing close until hitting to the generation of connecting plate 3 at connecting plate 3
Hit effect；
For steel ball 26 when hitting with connecting plate 3, the micarta 19 that steel ball 26 hits at circular hole makes its deformation until nylon rope
21 are straightened, then connecting plate 3 and conductive sheet 2 in the case where steel ball 26 hits the effect of inertia generated to socket internal motion one end away from
From plug and socket part being made to generate a little vibration in knockout process, shaken so that the connection of plug and socket is tighter herein
Cocoa makes the metal clips in conductive sheet 2 and socket generate certain gap in moment, so that there are the tune of moment therebetween
The whole time can be relieved the poor contact of partial picture；
Conductive plate 22 and an electrode of thermoelectric generation film 18 disengage when shock deforms micarta 19, so that electromagnetism
The power-off of iron 17 loses magnetic force and no longer attracts steel ball 26, and steel ball 26 restores initial position under the elastic force effect of third spring 27；
The material property of micarta 19 makes it have certain reset capability, when 19 reset strap moving conductive plate 22 of micarta again
When secondary and thermoelectric generation film 18 electrode offsets, electromagnet 17, which is once again powered up, attracts steel ball 26 to repeat above-mentioned movement, until socket
With the stable connection of plug, the electric current that the temperature difference of conductive sheet 2 and room temperature generates is not enough to the attraction steel ball 26 of drive electromagnet 17 and is
Only.When the connection of conductive sheet 2 and socket is in the state of poor contact always, electromagnet 17 can repeat always above-mentioned movement
So that steel ball 26 is constantly hit connecting plate 3, connecting plate 3 and conductive sheet 2 is driven to slide with respect to shell 1, until connecting plate 3 and the
Two sliding sleeves 14 offset and drive its sliding, and the rotation of rotating bar 12 at this time pulls the relatively fixed bar 10 of wedge block 11 to slide, until wedge
Shape block 11 does not offset with the square block 9 on plate 6, and control-rod 5, plate 6, first baffle 8, second baffle 16 are in the first bullet at this time
It is slided under the action of spring 7 to far from 2 direction of conductive sheet, second baffle 16 offsets to drive with connecting plate 3 during this slides together with it
It is dynamic, so that conductive sheet 2 is thoroughly extracted from socket, so that the electric connection of plug and socket thoroughly disconnects, avoids the two and connect
Touch it is bad cause heat largely accumulate even cause fire.
After user excludes the factor of poor contact manually, push lever 5 is until square block 9 is fastened on wedge shape again
When at block 11, conductive sheet 2 can be made to stretch out from shell 1, use plug of the invention convenient for next time.
Although shell 1, conductive sheet 2, connecting plate 3, sliding slot 4, control-rod 5, plate 6, the first bullet is used more herein
Spring 7, first baffle 8, square block 9, fixed link 10, wedge block 11, rotating bar 12, the first traveller 13, the first sliding sleeve 14, the second bullet
It is spring 15, second baffle 16, electromagnet 17, thermoelectric generation film 18, micarta 19, cylinder 20, nylon rope 21, conductive plate 22, thermally conductive
The terms such as bar 23, the second sliding sleeve 24, the second traveller 25, steel ball 26, third spring 27, but be not precluded using other terms can
It can property.The use of these items is only for be more convenient to describe and explain essence of the invention；It is construed as any one
The additional limitation of kind is disagreed with spirit of that invention.
