The safety door structure of the power socket comprises a socket shell body, a safety baffle, a safety door base and a reset bias piece. The safety baffle is of an integral structure and comprises a baffle body part and cover sheet parts located on the left side and the right side of the baffle body part respectively, the cover sheet parts comprise two-pin jack cover sheets arranged on the left side and the right side, upper three-pin jack cover sheets on the left side and the right side and lower three-pin jack cover sheets on the left side and the right side, the safety baffle is arranged on the safety door base and is used for covering two-pin jacks and three-pin jacks, and the reset bias piece is used for achieving the sliding of the safety baffle. The safety door structure of the power socket solves the problem that another pole jack is exposed after a two-pole plug or a three-pole plug is inserted into a five-hole socket, therefore, the safety of the socket is ensured, and accidental electric shocks can be prevented effectively.
Description
Technical field
The invention belongs to the electrical equipment connection area of power supply unit, particularly a kind of safety door structure of power socket.
Background technology
Supply socket is for household electrical appliance provide the electric equipment of power interface, also be use more electrical accessory in design of residence, it and people live very close relationship, low-quality supply socket usually causes physical electrical shock fire protection and electrical fire accident, major hidden danger is brought to personal safety as well as the property safety, so the design of supply socket is also the important evidence evaluating design of residence.
In order to realize the safe handling of socket, be provided with emergency exit in the jack of many supply sockets, also referred to as shutter; normally above sleeve component, arrange insulator, after plug inserts, insulator position moves and power supply is connected; after plug is extracted, insulator automatically resets.The safe design of socket mainly comprises the airtight design for socket water-proof function in the environment such as bathroom in the market, and prevents the electrode in child's finger touch jack and avoid because accidental misoperation occurs that one pole inserts the safety Design etc. that band electric jack causes harm of getting an electric shock.
In prior art, the use phenomenon of the holes shutter of standard normally one pole inserts any one hole of two spring hole scokets, inserts not enter, and two pins are inserted simultaneously and just can be inserted in two jacks; Anti-one pole for three-terminal polarized plus plug inserts design and generally comprises: one is earth electrode unprotect door, and fire, zero the two poles of the earth also will insert simultaneously and just can back down shutter; The second is that three poles have shutter, adopts the type of drive that earth polar is inserted, and when grounding pin backs down shutter, fire, zero the two poles of the earth shutter just can be opened.Corresponding standards for safe use is needed equally with three five spring hole scokets inserting jacks for inserting in conjunction with two, but in use at present, when use two jack or three inserts jack, capital causes the opposing party to be in exposed state, easily be splashed into water, or touch band electric jack unexpectedly and there is potential safety hazard, the security performance of socket is reduced, a kind of shutter modified node method of five spring hole scokets disclosed in Chinese patent document 202373747U, comprise the protective cover with two hole jacks and three hole jacks, two hole shutters of covering two hole jack are provided with in described protective cover, cover two hole shutters of three hole jacks, the two ends of described two hole shutters are offseted by shutter spring I and protective cover top side, are offseted in the middle part of described three hole shutters by shutter spring II and protective cover bottom side, three shutter upper end, holes are provided with the lead that is slidably connected with two hole shutters for covering the earth jack in three hole jacks, spacing catch is provided with between two hole shutters and three hole shutters, but in this structure, be separated independently parts because two hole shutters are two with three hole shutters, therefore, need to design respectively shaping, configuration three back-moving springs are needed to realize the reset of two hole shutters, three hole shutters in addition, therefore, the building block of this structure is many, not only the complicated trouble of assembling, and production cost is high, be unfavorable for the reduction of cost.
Summary of the invention
