When inserting plug, the slope root on the described slope on the right side of described slide block is in the face of described right jack;So, for left and right jack the most just
To described metal spring leaf, only after plug insertion socket, two pieces of metal spring leafs are just made to contact with the left and right pin of plug respectively,
Further increase the safety of socket.
As preferably, the metal spring leaf of described slide block left and right sides is connected with fire zero line the most respectively: left and right
The metal spring leaf of side forms moving contact respectively to the side of slide block;And be shaped with on the inwall of described slideway and described moving contact mutually
The static contact joined;At the fully-inserted socket of plug, when making described slide block slide into extreme position to the left, described moving contact and stationary contact
Head is the most in electrical contact;Otherwise, moving contact does not contacts with static contact;Described static contact is electrically connected to zero live wire;Thus, one is entered
Step improves the safety of socket.
The beneficial effects of the present invention is: this anti-electric shock socket is when being not inserted into plug, owing to being electrically connected at live wire
Metal spring leaf on the left of slide block deviates left jack and is placed between two jacks, therefore, even if stretching into a left side by finger or metal object
In jack, it is also difficult to touch the metal spring leaf on the left of slide block, thus avoid electric shock accidents;And when inserting plug, due to
Pin is inserted simultaneously at left and right jack, and therefore, right pin, by promoting slide block to be moved to the left by the slope on the right side of slide block, finally makes
Slide block is symmetrical about the symmetrical plane of two jacks, and now, the most outwards prop up plug two insert the metal spring leaf of slide block both sides
The inner side of foot, thus realize normal power-up;Based on this design philosophy, it is seen then that without using strength, and make slide block only with skilful power
Skew, it is achieved electricity interface purpose;Therefore, compared to current anti-electric shock socket, its plug is the most easy and convenient.

Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings:
In the embodiment shown in fig. 1, this anti-electric shock socket includes that pedestal 1, described pedestal 1 front are provided with two jacks 10,10 ';
The slideway 100 that the direction of insertion of described jack 10,10 ' is orthogonal in pedestal 1;A slide block it is provided with in described slideway 100
2;The two ends symmetry of this slide block 2 includes metal spring leaf 21,21 ', and described metal spring leaf 21,21 ' is in the face of jack side and slide block
Insulating element 22,22 ' on body is collectively forming slope;Wherein, described insulating element 22,22 ' forms the slope root on described slope.
In the present embodiment, being provided with slide block permanent magnet in described slide block 2, it forms S pole and N pole at slide block 2 two ends;Slideway
100 both sides are provided with the relative left permanent magnet 11 of heteropole, right permanent magnet 11 ';As it is shown in figure 1, described slide block permanent magnet and left permanent magnetism
Body 11, right permanent magnet 11 ' homopolarity are relative, and therefore, described slide block 2 is repelled by described left permanent magnet 11, right permanent magnet 11 ' simultaneously;
The magnetic of described left permanent magnet 11 is better than right permanent magnet 11 ';Therefore, in its natural state, described slide block 2 will be in magnetic repulsion effect
Under be equilibrated in slideway 100 and be partial to right jack 10 ' side.
Using the program that slide block 2 constitutes mechanics constraint, have is clearly advantageous that, it is not necessary to use mechanical elastic portion
Part, is not only difficult to damage, and it is extremely simple to assemble process.
For the difference that the magnetic of described left permanent magnet 11, right permanent magnet 11 ' is strong and weak, meet following condition: under naturalness,
That is when being not inserted into plug in described socket, described slide block 2, under magnetic repulsion retrains, deviates said two jack 10,10 '
Symmetrical plane, is biased in the right right jack 10 ' side, and now, the slope root of the described slope on the right side of described slide block 2 is just to right jack
10 ', the slope on the left of slide block is then deviateed left jack 10 and is placed between two jacks 10,10 '.In Fig. 2, the pin 41 of plug 4,
41 ' have just stretched into jack 10,10 ', are not inserted into plug in being equivalent to socket, it is seen then that now the right pin 41 ' of plug withstands cunning just
The slope root on the slope on the right side of block 2, left pin 41 is the most unsettled;Now the left and right pin of plug 4 is the most electrically isolated.
For the lateral dimension of described slide block 2, satisfied condition as in figure 2 it is shown, time in the fully-inserted socket of plug 4,
Due to right jack 10 ' just to described slide block 2 on the right side of slope, by the pushing of right pin 41 ', force slide block 2 to break away to the left
Having moved extreme position, now the metal spring leaf 21,22 ' of slide block 2 both sides outwards props up two pins 41,41 ' of plug 4 just
Inner side.
It addition, as shown in FIG. 1 to 3, the metal spring leaf 21,21 ' of slide block 2 left and right sides extends to the side of slide block respectively,
Form moving contact 211,211 ';And it is shaped with, on the inwall of described slideway 100, the stationary contact matched with described moving contact 211,211 '
31,31 ';When plug is not fully inserted into socket, as shown in Figure 1 and Figure 2, moving contact 211,211 ' and static contact 31,31 ' are not
Contact;And when the fully-inserted socket of plug, as it is shown on figure 3, now, described slide block 2 slides into extreme position to the left, described dynamic
Contact 211,211 ' and static contact 31,31 ' are the most in electrical contact;And described static contact 31,31 ' is electrically connected to zero live wire, tool
Body ground, static contact 31 connects live wire, and static contact 31 ' connects zero line;So, equal to there being double shield, further increase
The safety of socket.
