Anti-electric shock socket
Technical field
The present invention relates to electric power facility field, especially, relate to a kind of power receptacle.
Background technology
Power receptacle is the electric power facility on basis the most, is mainly terminal power consumption equipment and provides electricity interface.For two jacks of socket, often cause danger to children, because the curiosity of children is strong, awareness of safety is weak, very possible finger or metal object go to dig jack, then will cause electric shock phenomenon.
For the problems referred to above, the defensive measure of employing is at present, arranges the protective sheet that laterally can flick under plug thrust in the jack of socket, now, needs to adopt larger strength to push plug inwards, just protective sheet can be flicked, and plug insertion put in place.The Basic Design theory of this kind of socket is by pushing protective sheet open by force energetically, and makes less strength cannot push protective sheet open; Therefore in actual use, very inconvenient, also plug cannot be inserted situation about putting in place under often appearing in the tremendous effort, visible, there is obvious defect in the design of current anti-electric shock socket.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of anti-electric shock socket, this socket not only can prevent from touching jack because digging and causing electric shock, and plugs easy and convenient.
The technical solution adopted for the present invention to solve the technical problems is: this anti-electric shock socket comprises pedestal, and described pedestal front is provided with two jacks; The direction of insertion of described jack is orthogonal to a slideway in pedestal; A slide block is provided with in described slideway; The two ends symmetry of this slide block includes metal spring leaf, and described metal spring leaf is in the face of formation slope, jack side; When not inserting plug in described socket, described slide block is under the effect of constraint mechanism, depart from the symmetrical plane of described two jacks, be biased in right jack side to the right, now, described slope on the right side of described slide block is for right jack, and the slope on the left of slide block is then departed from left jack and is placed between two jacks; When inserting plug in described socket, right jack slope on the right side of just right described slide block by the right pin institute ejection of plug, slide block is forced to slide to the left, and after plug inserts completely, slide block slides into extreme position left, now the metal spring leaf of slide block both sides outwards props up the inner side of two pins of plug just, and now, the metal spring leaf on the right side of described slide block connects with zero line; And the metal spring leaf on the left of slide block connects with live wire.
As preferably, described constraint mechanism comprises as lower component: slideway both sides as described in being arranged on, the left permanent magnet that heteropole is relative, right permanent magnet; Be arranged at the slide block permanent magnet in described slide block; Two magnetic poles of described slide block permanent magnet and described left permanent magnet, right permanent magnet homopolarity are relative; The magnetic of described left permanent magnet is better than right permanent magnet.
As preferably, the slope of described slide block both sides is made up of jointly described metal spring leaf and insulating element; Described insulating element is in the inner side of described metal spring leaf, and namely insulating element forms the slope root on whole described slope; And when not inserting plug in described socket, the slope root on the described slope on the right side of described slide block is in the face of described right jack; Like this, for left and right jack all not just to described metal spring leaf, only after plug insertion socket, just make two pieces of metal spring leafs contact with the left and right pin of plug respectively, further increase the fail safe of socket.
As preferably, the metal spring leaf of described slide block left and right sides is connected with zero live wire in the following way respectively: the metal spring leaf of left and right sides forms moving contact respectively to the side of slide block; And the inwall of described slideway is shaped with the fixed contact matched with described moving contact; Insert socket completely at plug, when making described slide block slide into extreme position left, described moving contact and fixed contact are just in electrical contact; Otherwise moving contact does not contact with fixed contact; Described fixed contact is electrically connected to zero live wire; Thus, the fail safe of socket is further increased.
Beneficial effect of the present invention is: this anti-electric shock socket is not when inserting plug, due to be electrically connected at live wire slide block on the left of metal spring leaf depart from left jack and be placed between two jacks, therefore, even if stretch in left jack with finger or metal object, also be difficult to the metal spring leaf touched on the left of slide block, thus avoid electric shock accidents; And when inserting plug, because pin inserts at left and right jack simultaneously, therefore, right pin is moved to the left promoting slide block by the slope on the right side of slide block, finally make slide block symmetrical about the symmetrical plane of two jacks, now, the metal spring leaf of slide block both sides outwards props up the inner side of two pins of plug just, thus realizes normal power-up; Based on this design philosophy, visible, without the need to using brute force, and only adopting skilful power that slide block is offset, realizing electricity interface object; Therefore, compared to current anti-electric shock socket, its plug is very easy and convenient.

Embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
In the embodiment shown in fig. 1, this anti-electric shock socket comprises pedestal 1, described pedestal 1 front be provided with two jacks 10,10 '; The direction of insertion of described jack 10,10 ' is orthogonal to a slideway 100 in pedestal 1; A slide block 2 is provided with in described slideway 100; The two ends symmetry of this slide block 2 include metal spring leaf 21,21 ', described metal spring leaf 21,21 ' ' forms slope jointly at the insulating element 22,22 on jack side and slider body; Wherein, described insulating element 22,22 ' forms the slope root on described slope.
In the present embodiment, be 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 be provided with the relative left permanent magnet 11 of heteropole, right permanent magnet 11 '; As shown in Figure 1, described slide block permanent magnet and left permanent magnet 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 equilibrated in slideway 100 and be partial to right jack 10 ' side under magnetic repulsion effect.
Adopt the program to form mechanics constraint to slide block 2, the obvious advantage had is, without the need to adopting mechanical elastic parts, be not only difficult to damage, and assembling process is extremely easy.
For described left permanent magnet 11, right permanent magnet 11 ' the strong and weak difference of magnetic, meet following condition: under nature, that is when not inserting plug in described socket, described slide block 2 is under magnetic repulsion constraint, depart from described two jacks 10,10 ' symmetrical plane, be biased in right jack 10 ' side to the right, now, the slope root of the described slope on the right side of described slide block 2 just to right jack 10 ', the slope on the left of slide block is then departed from left jack 10 and is placed between two jacks 10,10 '.In Fig. 2, ' just stretched into jack 10,10 ', be equivalent to not insert plug in socket, visible, ' just withstand the slope root on the slope on the right side of slide block 2, left pin 41 is then unsettled for the right pin 41 of now plug for the pin of plug 4 41,41; Now the left and right pin of plug 4 is all electrically isolated.
For the lateral dimension of described slide block 2, the condition met as shown in Figure 2, when plug 4 inserts in socket completely, due to right jack 10 ' the slope on the right side of just right described slide block 2, by right pin 41 ' pushing, force slide block 2 to slide into extreme position to the left, now the metal spring leaf 21,22 ' of slide block 2 both sides just outwards prop up plug 4 two pins 41,41 ' inner side.
In addition, as shown in FIG. 1 to 3, the metal spring leaf of slide block 2 left and right sides 21,21 ' side respectively to slide block extends, formed moving contact 211,211 '; And the inwall of described slideway 100 is shaped with and described moving contact 211, the 211 ' fixed contact 31,31 ' matched; When plug does not insert socket completely, as shown in Figure 1 and Figure 2, moving contact 211,211 ' does not contact with fixed contact 31,31 '; And when plug inserts socket completely, as shown in Figure 3, now, described slide block 2 slides into extreme position left, described moving contact 211,211 is ' just in electrical contact with fixed contact 31,31 '; And described fixed contact 31,31 ' is electrically connected to zero live wire, particularly, fixed contact 31 connects live wire, and fixed contact 31 ' connects zero line; Like this, equal double shield, further increase the fail safe of socket.
Above-mentioned anti-electric shock socket, owing to being design based on the thought adopting skilful power to make slide block offset, therefore compared to current anti-electric shock socket, its plug is very easy and convenient.
