Description

A kind of shutter of five spring hole scokets improves structure
Technical field
The utility model relates to the shutter structure of supply socket, particularly a kind of shutter of five spring hole scokets.
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.But above-mentioned requirements is to two hole socket and Three-hole socket, for the corresponding standards for safe use of the same needs of five spring hole scokets of two hole socket and Three-hole socket combination; But still there is following defective in the shutter in present five spring hole scokets: when Three-hole socket used, the conducting strip of two hole socket was exposed, and when two hole socket used, the conducting strip of Three-hole socket was exposed; There is potential safety hazard in the user in using the process of supply socket like this, and possibly have foreign matter and fall in the socket.Therefore above-mentioned shutter structure is to satisfy the requirement safe in utilization of plate connectors such as five spring hole scokets.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 has potential safety hazard.
Summary of the invention
The utility model problem to be solved just provides a kind of shutter of five spring hole scokets, and structural design is simple, reasonable, overcomes the existing existing defective of five spring hole scoket shutters.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: a kind of shutter of five spring hole scokets improves structure; It is characterized in that: comprise the protective cover that has two hole jacks and three hole jacks, be provided with the two hole shutters that cover two hole jacks, the three hole shutters that cover three hole jacks in the said protective cover; The two ends of said two hole shutters offset through shutter spring I and protective cover top side, and shutter middle part, said three hole offsets through shutter spring II and protective cover bottom side; Shutter upper end, three holes is provided with the earth jack that the lead that is slidingly connected with two hole shutters is used for covering three hole jacks; Be provided with spacing catch between two hole shutters and the three hole shutters.
Further, the position of the corresponding two-wire plug insertion in the two ends of said two hole shutters respectively is provided with the wedge shape depressed part.After two-wire plug inserts, apply pressure to and upwards back down two hole shutters on the wedge shape depressed part, expose the L utmost point sleeve and the N utmost point sleeve of two hole socket.
Further, the lead end of said three hole shutters is provided with the inclined-plane.After three-terminal polarized plus plug inserted, its ground connection was inserted the utmost point and is applied pressure to and back down three hole shutters downwards on the inclined-plane, exposes the L utmost point sleeve and the N utmost point sleeve of Three-hole socket.
Further, the two ends of said two hole shutters are provided with the joint pin I that pegs graft with shutter spring I, and corresponding joint pin I position, protective cover top side is provided with spring mounting groove I; Shutter middle part, said three hole is provided with the joint pin II that pegs graft with shutter spring II, and corresponding joint pin II position, protective cover bottom side is provided with spring mounting groove II.Effectively fixedly the shutter spring prevents its dislocation of sliding.
Further, said spacing catch and protective cover are structure as a whole.
The beneficial effect of the utility model: adopt five spring hole scokets of the utility model, when using two hole socket, two hole shutters are pushed open, and three hole shutters keep original position; When using Three-hole socket, three hole shutters are pushed open, and two hole shutters keep original position; Two hole shutters and three hole shutters do not influence each other, and the potential safety hazard of user when using supply socket just reduces greatly, has good security performance; And the structural design of the utility model is simple, reasonable, is convenient to manufacture, and has better practicability.
