Two sides are fixed with extended oblique cutting bar 82 down, zygomorphism and up extended are provided in 7 upper end of receptacle portion
Balladeur train 9, the upper end of each balladeur train 9 are equipped with limited block 94, are equipped with pushing slot 93, Mei Gesuo in each balladeur train 9
It states 93 bottom surface of pushing slot and is equipped with the first pressure spring 92, slided between two pushing slots and be connected with conductive sheet 91, it is described
Up extended end is fixedly connected and lower press-fit first pressure spring 92 with 91 bottom surface of conductive sheet, the phase of 82 lower end of oblique cutting bar
The jack 71 for being cooperatively connected with the oblique cutting bar 82 is equipped in the receptacle portion 7 answered, it is described between the jack 71
It is equipped with the slide slot 72 of zygomorphism setting in receptacle portion 7, is equipped between the slide slot 72 and is fixedly connected with the receptacle portion 7
Baffle 77, each 72 upper end of slide slot, which is equipped with, is pierced by 7 roof of receptacle portion and the region phase between the balladeur train 9
Logical perforation 75, the perforation 75 is interior to be equipped with the conductive pin 78 for sliding mating connection, and each 72 bottom end of slide slot is equipped with
For improving the guide groove 73 for sliding stationarity and guiding function, is slided in each slide slot 72 and is equipped with power supply slide unit 74,
The second pressure spring 76 is equipped between each power supply slide unit 74 and the baffle 77,74 upper end of power supply slide unit is equipped with power supply
Hole 742, power supply 74 bottom end of slide unit are equipped with the convex block 743 for putting in the guide groove 73 and sliding mating connection, the power supply
Slide unit 74 is equipped with angled end 741 away from described second pressure spring, 76 one end, and the angled end 741 is pierced by the receptacle portion 7 and puts in
In the jack 71.
Wherein, the power connecting sheet 81 is electrically connected with the conducting wire 83, and the conductive pin and the power supply hole are electrically connected,
To realize for electrical connection.
Wherein, the groove width of the pushing slot 93 is equal with 91 width of conductive sheet, thus stability when increasing downslide.
Wherein, the self gravity of the receptacle portion is greater than the first pressure spring maximum flexibility power, so that more steady when grafting
Gu the power supply slide unit is insulation slide unit, prevent personnel from accidentally touching increase Supply Security.
When original state, plug division 8 deviates from receptacle portion 7, and power supply slide unit 74 passes through the active force of the second pressure spring 76, thus will
In the press of angled end 741 and the jack 71 powered on slide unit 74, meanwhile, 78 bottom end of conductive pin and power supply slide unit 74 in perforation 75
Upper surface abuts against, meanwhile, 78 upper end of conductive pin is put in balladeur train 9.
It is mobile towards 7 side of receptacle portion by control plug division 8 when grafting being needed to power, put in oblique cutting bar 82 gradually slotting
In hole 71, until the inclined-plane and the inclined-plane in angled end 741 of 82 bottom end of oblique cutting bar compress and slide cooperation, oblique cutting bar 82 continues down
Sliding makes angled end 741 drive power supply slide unit 74 that the active force of the second pressure spring 76 is overcome gradually to move into slide slot 72, when oblique
