Abstract
The problem that the present utility model is very easily got an electric shock when inserting for the ordinary plug occurred in actual production, life devises a kind of electric equipment novel anti-shock plug, can in plug insertion process Circuit Interrupt, insert completely after staff leaves Deng plug and be energized again, can avoid and solve plug unsafe factor in actual use.Adopt electric shock arc-control device, utilize permanent magnet to avoid generation electric arc or electric spark when circuit is connected suddenly.Adopt the plug of technical scheme manufacture described in the utility model to have structure feature simple, with low cost while raising fail safe, the needs be specially adapted in household electrical appliance and industrial electrical equipment prevent the plug of electric shock and electric arc.
Description
Technical field
The present invention relates to and be a kind ofly used in conventional electric equipment the plug needing often plug, particularly relate to and be a kind ofly widely applied to the novel plug that can prevent from getting an electric shock and eliminating electric arc power good required in extra high household electrical appliance and industrial electrical equipment.
Background technology
To be absolutely necessary a kind of element as the plug of mains connection in the modern life and in producing, traditional plug is made up of plastics stand, sheet metal, other fastening screws etc.
Along with improving constantly of people's living standard, various household electrical appliance also enter in our daily life thereupon, but we are enjoying its threat being also subject to it at one's leisure.Electricity is breakneck as you know, but we again time to often see some children, old man and the people that has defective vision, when using household electrical appliance plug plug, because coordination is bad, light is dark, or it is incorrect to grasp plug gesture, not careful, finger tip is all easy to those two sheet metals before encountering plug, and the lighter can taste the misery be electrically shocked, and severe one is entail dangers to life even.
Plug is used on life and the electric equipment used by production, and the plug in prior art does not consider safety factor when designing, and often electric shock accidents occurs in use, brings no small harm and economic asset loss to user.Electric shock thing occurs in when plug is inserted into socket sometimes; when plug is inserted into socket, during use traditional plug, circuit is switched on now staff at once and does not leave plug; often can produce electric spark when circuit is connected suddenly at slotting spring and Plug contact place when use voltage is higher or be connected to potential device after plug, this is breakneck.And if the circuit aging electric wire of plug inside is exposed or wet hand time staff do not leave when circuit ON plug be also now be very easy to occur electric shock accidents.So design one can in plug insertion process Circuit Interrupt, the plug waiting plug to insert completely to be energized again after staff leaves is very important.
Summary of the invention
The present utility model for the problem that the ordinary plug that occurs in actual production, life very easily gets an electric shock when inserting devise one can in plug insertion process Circuit Interrupt, insert the plug be energized again after staff leaves Deng plug completely, can avoid and solve plug unsafe factor in actual use.Adopt electric shock arc-control device, utilize permanent magnet to avoid generation electric arc or electric spark when circuit is connected suddenly.Adopt the plug of technical scheme manufacture described in the utility model to have structure feature simple, with low cost while raising fail safe, the needs be specially adapted in household electrical appliance and industrial electrical equipment prevent the plug of electric shock and electric arc.
For solving the problem, the utility model by the following technical solutions:
A plug core is only had in plug described in the utility model, plug core kink is in plug body, inserted sheet and L shape plug core insulation crust form plug core jointly, plug inside is equipped with fixed contact, fixed contact is connected with wire with the electrical appliance after plug, vertical plug core spacing hole is equipped with in plug body inside, and plug body interior bottom portion is equipped with end magnetic, and plug core kink is inner at plug body.Wherein plug core magnetic is housed bottom plug core, plug core magnetic is permanent magnet with end magnetic and magnetic pole of the same name is relative.
Inserted sheet and plug core insulation crust together form plug core, and inserted sheet is L shape conductive metal sheet, and be moving contact bottom L shape inserted sheet, the quantity of plug core inserted sheet can change as required.
The utility model adopts electric shock arc-control device, and the magnetic field utilizing permanent magnet to produce is avoided producing electric arc or electric spark when circuit is connected suddenly.
The utility model is invented to compare with conventional apparatus and other has following technique effect:
1) plug adopting technical scheme described in the utility model to manufacture, plug core can move up and down in plug, and when plug insertion socket, plug core moves downward, and makes internal circuit access failure, now can protect user.
2) magnetic force moving plug core is produced between magnet poles when staff unclamps, make contact, plug inside circuit ON, even if be now connected to high-power electric appliance, transformer after plug or adopt high voltage to avoid under the effect of permanent magnet or to reduce electric arc and electric spark, thus improving security performance.
3) plug of technical scheme manufacture described in the utility model is adopted to have structure feature simple, with low cost while raising fail safe.
4) magnetic field utilizing permanent magnet to produce can be avoided producing electric arc or electric spark when circuit is connected suddenly.
