The working principle of the invention is: the active unit when the plug of electrical appliance is inserted into jack, inside movable housing 6
10 under the action of the spring be in normal position, with forward slip trend, and sliding slot 11 it is end-acted under, to active shell
Body 6 also generates the trend of forward slip, thus under normal conditions, movable housing 6 always protrudes from the surface of cover board 3.And
Under the action of locking wedge, movable housing 6 is whole locked, cannot slid inward under the effect of external force.And it can connect at this time
The part of logical alternating current is only each conductive sheet 17 on bottom cover 14, and conductive sheet 17 obviously can not be contacted with the external world, because without depositing
In Danger Electric shock risk.
When plug is inserted into jack by user, it is divided into following process:
It is that the terminal of plug enters jack first, terminal is can not still to touch conductive sheet 17 at this time, can not be normal
It is powered, even if so user touches terminal accidentally and is also impossible to get an electric shock at this time.
It is continued into then as plug, terminal will be in contact with active unit 10.Preferably, the activity
Unit 10 is equipped with the slot to match with two-pin plug or three-pin plug;The size of each slot is less than two-pin plug or three feet
The size of plug corresponding terminal, and the open setting in outside of slot, make the bottom surface of slot that can partially contact at two-pin plug or three
The corresponding terminal end face of n pin package n, forms the plane of constraint of an axial direction.And as a further preference, the inside of the slot
Front end is equipped with the lead-in chamfered 13 being gradually inclined outwardly, the tail end and two-pin plug of lead-in chamfered 13 or each end of three-pin plug
It is interference fitted between sub- inside.The terminal of plug enters correctly into slot, and the end face of terminal under the guidance of lead-in chamfered 13

The terminal of plug is first to be fully inserted into masking inside jack, then completes to be powered again, thus before energization user no matter
The terminal that can not touch plug again how has prevented the dangerous of electric shock.
Due to there is spring to generate reset response power between active unit 10 and bottom cover 14 always, if conductive sheet 17 and electric mortiser
Frictional force is insufficient between the terminal of head, is difficult to that plug is made to remain powered on state.Once the terminal of plug automatically exits from,
" unlock " effect of this " key " will fail, and all components can all reset one by one, and the terminal of plug can be final
Power loss.In order to increase between conductive sheet 17 and plug terminal effectively contacting, preferably, the front end of the conductive sheet 17 to
Interior U-bend is bent, forms a resilient engagement end 18;It is each that the resilient engagement end 18 of each conductive sheet 17 corresponds to active unit 10
