Abstract
The invention discloses a dipolar interlocking protection door of a socket, and the dipolar interlocking protection door is arranged between jacks and plug bushes and comprises a first slider and a second slider, wherein the first slider and the second slider are sheathed mutually and can slide relative to each other; the first slider is provided with a first wedge and a first door plank corresponding to a first jack; the second slider is provided with a second wedge and a second door plank which correspond to a second jack; the first door plank is arranged below the second wedge; the second door plank is arranged below the first wedge; and back ends of the first slider and the second slider are provided with an elastic part respectively. Corresponding to each jack, the wedge and the door plank form a vertically-laminated dual-layer protection door structure and spring forces are used for closing the protection door usually. The protection door is simple in structure, has an interlocking function, can be used for avoiding single-pin insertion effectively, has stronger single-pin insertion resisting capacity, and can be used for improving the safety of products greatly.
Description
Technical field
The present invention relates to the socket field, particularly a kind of shutter that can realize interlocking that is applied to two pole sockets.
Background technology
The fail safe of using in order to improve socket; avoid because misoperation or child are ignorant of occurring the contingency of getting an electric shock; how below the receptacle sockets of the two poles of the earth, shutter is set above sleeve; during work; two electrode plugs insert jack; shutter is opened, and engaged with the sleeve of its below, complete normal electrical connection.
Chinese patent literature CN2373908 discloses a kind of raising type socket protective door, and it adopts the flip-shell principle, the sleeve in it is formed to hide stop to prevent to get an electric shock, but it can not prevent from that one pole from inserting the electric shock caused fully.
Chinese patent literature CN2497446 discloses a kind of the two poles of the earth socket protective door assembly, and when one pole inserts, shutter makes it can not contact sleeve; can prevent when one pole from inserting the electric shock formed; but its complex structure, reliability is low, and the requirement to socket protective door in GB GB2099.1-2008 has two:
(1) thrust that the probe that, the probe of 3 * 1mm applies the thrust of 20N and φ 1mm applies 1N is untouchable live part all;
(2), for inserting the shutter designed, anti-one pole should be able to bear the single latch insertion force that is greater than 75N.Above-mentioned shutter structure still exists the excessive danger that causes electric shock of insertion force.
Summary of the invention
The purpose of this invention is to provide a kind of two novel pole socket interlock protection doors, can form the two poles of the earth interlock protection, and there is better anti-single pin insertion ability.
The objective of the invention is to be achieved through the following technical solutions:
A kind of two pole socket interlock protection doors, be installed between jack and sleeve, the first slide block and the second slide block that mutually are linked in together and can relative sliding, consists of; Corresponding the first jack of the first slide block has the first voussoir and the first door-plate; Corresponding the second jack of the second slide block has the second voussoir and the second door-plate; Described the first door-plate is positioned at the second voussoir below, and described the second door-plate is positioned at the first voussoir below, and described the first voussoir and the second voussoir are in the same way to be arranged; Described the first slide block and the second slide block rear end are equipped with elastomeric element, and described elastomeric element is positioned at the same side of the first slide block and the second slide block, and direction of motion when described the first slide block moves with the second slide block simultaneously is identical.
Preferably, described elastomeric element is spring.
Shutter of the present invention, corresponding each jack, consist of the double shielding door of stacked on top of one another voussoir and door-plate, by spring force, shutter is closed at ordinary times; When single pin inserts, can rely on wedge surface to push voussoir open, open the upper strata shutter, the door-plate be positioned at below it forms lower floor's shutter, is subject to another jack lower wedge block control and do not open, and therefore single pin can not insert the socket power taking; When two latches insert simultaneously, the levels shutter is opened simultaneously, can normally insert like a cork sleeve, completes normal electrical connection; When plug is transferred to, shutter again resets and closes.This shutter is simple in structure, has interlock function, and when single pin inserts, the door-plate motion is subject to another jack lower wedge block to control and can not open, and makes it to have stronger anti-single pin insertion ability.
The accompanying drawing explanation
Below according to drawings and embodiments the present invention is described in further detail.

Embodiment
As shown in Fig. 1-6, provide the composition structural representation of two pole socket interlock protection doors of the present invention, it is installed between the jack and sleeve of socket panel 3, the first slide block 1 and the second slide block 2 that mutually are linked in together and can relative sliding, consists of; Corresponding the first jack of the first slide block 1 has the first voussoir 11 and the first door-plate 12; Corresponding the second jack of the second slide block 2 has the second voussoir 21 and the second door-plate 22; Wherein the first door-plate 12 is positioned at the second voussoir 21 belows, and the second door-plate 22 is positioned at the first voussoir 11 belows, and the first voussoir 11 and the second voussoir 21 are in the same way to be arranged; For any slide block, when plug inserts, can rely on wedge surface to promote voussoir, thereby make whole slide block along moving perpendicular to direction of insertion, direction of motion when the first slide block 1 moves with the second slide block 2 simultaneously is identical, the first slide block 1 and the second slide block 2 rear ends are respectively equipped with spring 13 and spring 23, can make slide block return to original position when plug is extracted.
With reference to Fig. 7, the action principle of this two pole sockets interlock protection door is as follows: corresponding each jack, formed the double shielding door of stacked on top of one another by voussoir and door-plate, and by spring force, shutter is closed at ordinary times; When single pin inserts, can rely on wedge surface to push voussoir open, open the upper strata shutter, the door-plate be positioned at below it forms lower floor's shutter, is subject to another jack lower wedge block control and do not open, and therefore single pin can not insert the socket power taking; When two latches insert simultaneously, the levels shutter is opened simultaneously, can normally insert like a cork sleeve, completes normal electrical connection; When plug is transferred to, shutter again resets and closes.
This shutter is simple in structure, has interlock function, and when single pin inserts, the door-plate motion is subject to another jack lower wedge block to control and can not open, and makes it to have stronger anti-single pin insertion ability.
