Description
Technical field
The present utility model relates to a kind of plug be used in conventional electric equipment, and particularly one can extensive use
Background technology
To be absolutely necessary a kind of element as the plug of mains connection in modern society's life and in producing, traditional plug is made up of plastics stand, sheet metal, other fastening screws etc., be used on life and the electric equipment used by production, plug in prior art does not consider safety factor when designing, often there is electric shock accidents in use, bring 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.
For solving the problem, the utility model by the following technical solutions:
Socket described in the utility model is arranged on inserted sheet in plug core and forms a mechanism, 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 permanent magnet, permanent magnet is contained between plug body and fixed contact, plug inside permanent magnet 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, plug body interior bottom portion is equipped with spring retainer groove, spring is contained in spring retainer groove, plug core kink is inner at plug body, bottom L shape plug core insulation crust and spring contact.Described inserted sheet and plug core insulation crust together form plug core.Described inserted sheet is L shape conductive metal sheet, is moving contact bottom L shape inserted sheet.The quantity of plug core and plug core spacing hole can change as required.
The utility model adopts electric shock arc-control device, utilizes permanent magnet to avoid to produce 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 is plug inside circuit access failure when plug insertion socket, now can protect user.
2) when staff unclamps, contained spring promotes plug core, 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 improves 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.
