Description
Technical field
The utility model relates to the socket field, particularly a kind of composite type interlock protection door that is applied to five spring hole scokets.
Background technology
In order to improve the fail safe that socket uses; avoid the contingency that is ignorant of getting an electric shock owing to misoperation or child; how below the receptacle sockets, above the sleeve shutter is set; during work; the two poles of the earth plug or two utmost point band ground pins insert jack; shutter is opened, and engaged, finish normal electrical connection with the sleeve of its below.
Chinese patent literature CN201674088 discloses a kind of shutter structure that is used for five spring hole scokets, and its two poles of the earth jack adopts the seesaw type structure, and two utmost point band earth jacks adopt the combined protective door that just can open L, the N utmost point after ground hole is opened earlier; Sleeve in it form hidden stop and prevent to get an electric shock, can play preventing that the two poles of the earth jack one pole from inserting effect.
Requirement to the socket protective door among the GB GB2099.1-2008 has two:
(1), the probe of the 3 * 1mm probe that applies the thrust of 20N and φ 1mm applies all untouchable live part of thrust of 1N;
(2), the shutter that designs for anti-one pole insertion should be able to bear the single latch insertion force greater than 75N.Above-mentioned shutter structure still exists certain displacement when one pole insert to form locking, anti-single pin insertion ability a little less than.
Summary of the invention
The purpose of this utility model provides a kind of five novel spring hole scoket composite type interlock protection doors, can form the two poles of the earth interlock protection to the two poles of the earth jack, and has better anti-single pin insertion ability.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of five spring hole scoket composite type interlock protection doors, be installed between jack and the sleeve, form two pole socket interlock protection doors by first slide block and second slide block that are linked in mutually together and can slide relative, corresponding first jack of first slide block has first voussoir and first door-plate; Corresponding second jack of second slide block has second voussoir and second door-plate; Described first door-plate is positioned at second voussoir below, and described second door-plate is positioned at first voussoir below; The 3rd slide block constitutes two utmost point band grounding receptacle shutters, and its corresponding earth jack has the 3rd voussoir, and corresponding L, N utmost point jack have the 3rd door-plate, and described first slide block, second slide block and the 3rd slide block rear end are equipped with elastomeric element.
Preferably, described elastomeric element is a spring.
Especially, the 3rd door-plate on described the 3rd slide block is swallowtail shape, can carry out shutoff simultaneously and opens L, N utmost point jack.
Further, described the 3rd slide block is positioned at the middle chute that first slide block and second slide block form, can it slides up and down relatively.
Five spring hole scoket composite type interlock protection doors described in the utility model, each jack of corresponding two pole sockets constitutes the double shielding door of stacked on top of one another by 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 that is positioned at below it constitutes lower floor's shutter, is subjected to another jack lower wedge block control and does not open, and therefore single pin can not insert the socket power taking; When two latches inserted simultaneously, the levels shutter was opened simultaneously, can normally insert sleeve like a cork, finished normal electrical connection; When plug was transferred to, shutter resetted again and closes; Two utmost point band earth jacks only just can be opened the combined protective door of L, the N utmost point after ground hole is opened earlier.This shutter is simple in structure, and the two poles of the earth jack can form the two poles of the earth interlock protection, has stronger anti-single pin insertion ability, can prevent the generation of accidental shock accident effectively.

Embodiment
Shown in Fig. 1-7, provide the composition structural representation of five spring hole scoket composite type interlock protection doors described in the utility model, it is installed between the jack and sleeve of socket panel 4, forms two pole socket interlock protection doors by first slide block 1 and second slide block 2 that are linked in mutually together and can slide relative; First slide block, 1 corresponding first jack has first voussoir 11 and first door-plate 12; Second slide block, 2 corresponding second jacks have second voussoir 21 and second door-plate 22; Wherein first door-plate 12 is positioned at second voussoir, 21 belows, and second door-plate 22 is positioned at first voussoir, 11 belows; 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, first slide block 1 and 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.
The 3rd slide block 3 constitutes the shutter of two utmost point band grounding receptacles; be positioned at the middle chute that first slide block and second slide block form; can it slides up and down relatively; its corresponding earth jack has the 3rd voussoir 31; corresponding L, N utmost point jack have the 3rd door-plate 32; be swallowtail shape, can carry out shutoff simultaneously and open L, N utmost point jack.When plug inserted, ground pin can rely on the wedge surface of the 3rd voussoir 31 to promote the 3rd slide block 3, thereby the 3rd door-plate 32 of L, N utmost point jack below is moved, and L, N utmost point latch can be inserted; The 3rd slide block 3 rear ends are provided with spring 33, can make slide block return to original position when plug is extracted.
With reference to Fig. 8, the action principle of two pole socket interlock protection doors is as follows: corresponding each jack, constitute 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 that is positioned at below it constitutes lower floor's shutter, is subjected to another jack lower wedge block control and does not open, and therefore single pin can not insert the socket power taking; When two latches inserted simultaneously, the levels shutter was opened simultaneously, can normally insert sleeve like a cork, finished normal electrical connection; When plug was transferred to, shutter resetted again and closes.Two utmost point band earth jacks just can be opened the shutter below L, the N utmost point jack after ground hole is opened earlier.
This shutter is simple in structure, flexible movements, and the two poles of the earth socket protective door has interlock function; when single pin inserts; the door-plate motion is subjected to another jack lower wedge block control and can not opens, and makes it to have stronger anti-single pin insertion ability, can prevent the generation of accidental shock accident effectively.
