Description
Technical field
The utility model relates to a kind of shutter structure of socket, belongs to the technical field of appliance socket safety.
Background technology
Shutter also is " emergency exit ", the socket promptly said at ordinary times " safety socket " of band shutter, and insulator is equipped with in the sleeve component top of this socket, need could insert plug with bigger power during use; After plug was pulled out, the insulation physical efficiency automatically reset, and also can not get an electric shock even finger has put in socket aperture because of carelessness, is particularly conducive to and prevents that child from getting an electric shock.
Socket in the market is of a great variety, even some product has shutter, but still can insert with screwdriver or key, because of unreasonable the causing of its shutter design.General technology better and the shutter of National standard needs to adopt anti-one pole to insert design.The two poles of the earth plug has only two pins to insert simultaneously and could shutter be backed down; The anti-one pole of three-terminal polarized plus plug inserts generally has two kinds of designs, and the one, earth electrode unprotect door, fire, zero the two poles of the earth also will be inserted simultaneously just and can be backed down shutter; Second kind is that three utmost points all have shutter, and when grounding pin backed down shutter, fire, zero the two poles of the earth shutter just can be opened.
It is CN201020188089.6 that China national Patent Office discloses the patent No. on December 15th, 2010; Name is called a kind of patent that is used for the shutter structure of five spring hole scokets; The disclosed technical scheme of this patent comprises base, pressing plate, shutter, spring, cover group; One end of spring props up shutter, and the other end props up cover; It adopts single piece type independent protective door, realizes the slotting defencive function of porous, is applicable to five spring hole scokets, and the defective of existence is: when one group of jack was opened, another group jack unavoidably also can be opened, and in fail safe, has certain hidden danger.In view of above-mentioned defective, it is CN201020188112.1 that China national Patent Office discloses the patent No. on February 20th, 2011 again, and name is called a kind of patent that is used for the shutter structure of five spring hole scokets; Adopt dual spring, two shutter structure, utilize the seesaw principle, not only avoided the one pole insertion; And two shutter mutually noninterferes, overcome the existing defective of the former patent, but owing to adopt dual spring to reset; Cause the socket internal structure complicated, be unfavorable for making.The space that also has further simplification to the shutter structure of five spring hole scokets.
Summary of the invention
The utility model problem to be solved just provides a kind of shutter structure of five spring hole scokets, can effectively avoid one pole to insert, and has good security performance, and the product overall structure is simple more, reasonable, has better practicability.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: a kind of shutter structure of five spring hole scokets; Comprise the panel, pressing plate, sleeve component and the base that set gradually; Pressing plate is provided with shutter and following shutter, it is characterized in that: said going up between shutter middle part and the following shutter middle part connects through a back-moving spring; Said pressing plate is provided with first earth jack of ground connection sleeve in the corresponding sleeve component, and said upward shutter is provided with second earth jack of corresponding first earth jack.
Further, the said shutter middle part of going up is provided with the positioning boss to lower convexity, and said shutter middle part down is provided with the location notch that caves inward, and said back-moving spring is installed between positioning boss and the location notch.Make full use of the socket inner space, the volume when saving the back-moving spring installation.
Further; Said pressing plate center has spacing longitudinally gathering sill; Said first earth jack is arranged in the spacing gathering sill, and the said shutter of going up is provided with the spacing gib block I that cooperates with spacing gathering sill, and the length of spacing gib block I is greater than the length of first earth jack.Spacing gib block I is supported in the spacing gathering sill of following pressing plate all the time, makes the shutter can be not stuck in first earth jack of pressing plate in folding process.
Further, said shutter down is provided with the spacing gib block II that cooperates with spacing gathering sill.
Further, said pressing plate is provided with when the two poles of the earth plug one pole inserts shutter moves down in the restriction first position limiting structure and shutter moves up under the restriction when three-terminal polarized plus plug L inserts the utmost point or N and inserts the utmost point and insert second position limiting structure.
Further, said first position limiting structure is arranged on two catch I on the pressing plate for the corresponding shutter two ends of going up; Said second position limiting structure is arranged on two catch II on the pressing plate for corresponding shutter two ends down.
Further, said position of going up the plug insertion of corresponding the two poles of the earth, shutter both sides respectively is provided with the first wedge shape depressed part; The position that the L of the corresponding three grades of plugs in said shutter both sides down inserts the utmost point and the slotting utmost point insertion of N is provided with the second wedge shape depressed part.
The beneficial effect of the utility model:
Can know through such scheme: the utility model has adopted the two shutter structures of single spring, and the product overall structure is simple more, reasonable, and cost reduces; Last shutter all utilizes the seesaw principle with following shutter, has effectively avoided the one pole insertion, has good security performance; Compare existing pair of shutter five spring hole scokets, the utility model is more convenient for manufacturing, and has better practicability.
