Abstract
The utility model discloses a kind of safety plug, comprise plug body and inserted sheet, described inserted sheet is arranged on the lower end of described plug body, described inserted sheet structure is from outside to inside followed successively by insulating barrier and conductive layer, the lower end of described inserted sheet is provided with elasticity and touches ear, it is that the centre that described elasticity touches ear is connected with described conductive layer that described elasticity touches ear, and the both sides that described elasticity touches ear encase described inserted sheet, and described elasticity is touched after ear is under pressure and can be extended along described inserted sheet direction.The inserted sheet skin of safety plug of the present utility model is wrapped up by insulating barrier completely, can effectively prevent child because touching inserted sheet the electric shock accidents that causes, the advantage such as there is plug in addition and female contact is good.
Description
Technical field
The utility model relates to plug field, specifically relates to a kind of safety plug.
Background technology
Its inserted sheet of existing plug is generally all made up of simple metal, and easily cause inserted sheet to be on the one hand still connected with the seat core in socket when plug plug, inserted sheet is outside exposed again on the one hand.Although exposed just very little together gap, comparatively thin for their finger child, still there is the danger occurring to get an electric shock.
Utility model content
(1) technical problem that will solve
For the deficiency that prior art exists, the utility model provides a kind of safety plug that effectively can prevent getting an electric shock.
(2) technical scheme
For achieving the above object, the utility model provides a kind of safety plug, comprise plug body and inserted sheet, described inserted sheet is arranged on the lower end of described plug body, described inserted sheet structure is from outside to inside followed successively by insulating barrier and conductive layer, and the lower end of described inserted sheet is provided with elasticity and touches ear, and the centre that described elasticity touches ear is connected with described conductive layer, the both sides that described elasticity touches ear encase described inserted sheet, and described elasticity is touched after ear is under pressure and can be extended along described inserted sheet direction.
Further, the material of described conductive layer is copper.
Further, described insulating barrier is polytetrafluoroethylene.
Further, described elasticity touches the material of ear is beryllium-bronze.
Further, described elasticity touches the shape of ear is Ω shape.
Further, the height that described elasticity touches ear is greater than 5mm and is less than 10mm.
(3) beneficial effect
The inserted sheet skin of the utility model safety plug is wrapped up by insulating barrier completely, can effectively prevent child because touching inserted sheet the electric shock accidents that causes, the advantage such as there is plug in addition and female contact is good.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the utility model safety plug;
Fig. 2 is the structural representation of inserted sheet in the utility model safety plug;
Fig. 3 is the structural representation of inserted sheet in the utility model safety plug using state.
Wherein 1 is inserted sheet, and 2 is plug body, and 3 touch ear for elasticity, and 4 is socket seat core, and 5 is switch, and 11 is insulating barrier, and 12 is conductive layer.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
The structure of a kind of safety plug of the present utility model as depicted in figs. 1 and 2, comprise plug body 2 and inserted sheet 1, described inserted sheet 1 is arranged on the lower end of described plug body 2, described inserted sheet 1 structure is from outside to inside followed successively by insulating barrier 11 and conductive layer 12, the lower end of described inserted sheet 1 is provided with elasticity and touches ear 3, the centre that described elasticity touches ear 3 is connected with described conductive layer 12, and the both sides that described elasticity touches ear 3 encase described inserted sheet 1, and described elasticity is touched after ear 3 is under pressure and can be extended along described inserted sheet 1 direction.
Wherein, the material of described conductive layer 12 is copper; Described insulating barrier 11 is polytetrafluoroethylene; The material that described elasticity touches ear 3 is beryllium-bronze; The shape that described elasticity touches ear 3 is Ω shape; Described elasticity is touched the height of ear 3 under natural retracted position and is greater than 5mm and is less than 10mm.Elasticity can be kept under this length to touch the good contact of ear 3 and socket seat core, and ear 3 is long easily to be touched by child to prevent again elasticity from touching.Polytetrafluoroethylene is high temperature flame-retarded plastic, and insulating barrier 11 adopts polytetrafluoroethylene, and not only insulation effect is good, can also improve the security performance of whole plug by fire resistant.Described elasticity touches ear 3 not only needs less resistance also to need to have good elasticity, adopts beryllium-bronze can meet above two kinds of requirements preferably simultaneously.
In addition, the conveniently use of the utility model safety plug, plug body 2 is also provided with switch 5, and the setting of described switch 5 can reduce the plug number of times of plug, thus reduces the wearing and tearing of plug, improves the useful life of plug.
Fig. 3 is the structural representation of inserted sheet in the utility model safety plug using state.1 is inserted sheet in the drawings, and 4 is socket seat core, and 3 is elastic contact blade; Wherein elastic contact blade 3 is in compression elongation state under the pressure of socket seat core 4.When plug does not insert socket, elastic contact blade 3 bends to circle, and the height of elastic contact blade 3 can be made so low as much as possible, thus prevents the process Elastic contact 3 inserted at plug from contacting with socket seat core 4 and human body simultaneously.After plug insertion socket, elastic contact blade 3 extends under the extruding of socket seat core 4, thus ensures that elastic contact blade 3 fully contacts with socket seat core 4.
The beneficial effects of the utility model: inserted sheet skin is wrapped up by insulating barrier completely, can effectively prevent child because touching inserted sheet the electric shock accidents that causes, the advantage such as there is plug in addition and female contact is good.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
