Abstract
The electric kettle attaching plug, mains switch of serial connection on the on line of electric kettle plug.At the mains switch two ends of an electric kettle plug resistance in parallel and an indicator light.The utility model has guaranteed the normal use of electric kettle substantially by switch.Protected the electric kettle plug and socket of power source, in energy-conservation also beneficial.
Description
Technical field
The utility model relates to a kind of electric kettle power connector.
Background technology
Electric kettle still has purposes very widely, although the consumption of electric hot water bottle is more and more many.Electric kettle is the low and boiler easy to manufacture of a kind of cost, and easy to use, pollution-free, the energy utilization is abundant, even uses electric kettle to add ratio of specific heat and use combustion gas to boil water more cheap.But existing electric kettle is switched on or switched off power supply with the plugs and sockets plug, because about the general 1500W of power of electric kettle, the electric current of plugs and sockets carrying reaches more than the 7A, on-load is big, directly during the plug plug, switches on or off power supply moment at every turn, will inevitably produce electric spark, electrically contact the ablated oxidation of place's meeting, and loose contact, so that contact resistance strengthens, the plug heating, increased the excess loss of electric energy, reduced the heat efficiency of kettle, the electrode contact position of plugs and sockets heating easily burns out, can cause the insulating barrier of plugs and sockets to damage, therefore, can increase user's use cost, socket damages also needs professional electrician to change.
Summary of the invention
The purpose of this utility model is: a kind of electric kettle power source special connector is provided, and electrically contacting the place can ablated oxidation, overcomes the plugs and sockets insulating barrier and damages and need the puzzlement often changed, improves the heat efficiency of kettle indirectly, and guarantees the normal use of kettle.
The purpose of this utility model is achieved in that the electric kettle attaching plug, it is characterized in that mains switch of serial connection on the lead on line of electric kettle plug.
Under the situation of the cut-out of this switch, just under the situation of idling lotus, with the plug socket or transfer to socket, again mains switch is connected behind the socket, under the situation that mains switch disconnects, transfer to socket more simultaneously.Plug does not produce electric spark when plug like this, thereby guarantees that electrically contacting of plug and socket is good, electrically contacts the place and is not easy to produce the phenomenon of oxidation.The mains switch of series connection is selected the specification of 10A for use, though switch contact also can produce electric spark, but because the speed of switch is fast, the spark that produces is little, switch is that the specialized designs manufacturing is used to electrically contact, the often silver-plated or platinum of contact surface etc. can be anti-oxidant high temperature resistant, so normal use chronic of switch.
Characteristics of the present utility model are: guaranteed the normal use of electric kettle substantially by switch.Protected the electric kettle plug and socket of power source, in energy-conservation also beneficial.
Description of drawings
Fig. 1 is the utility model circuit diagram
Lead 1, the plug 2 that connects power supply, the plug 3 that connects the electric kettle socket, resistance 4, indicator light 5.
Embodiment
The utility model is a resistance in parallel and an indicator light at the mains switch two ends, indicator light is generally used light-emitting diode (LED), to make things convenient for the situation of user's testing circuit, under the situation that mains switch disconnects, plug inserts supply socket, and indicator light is bright, and indication circuit is normal, can Closing Switch, make kettle work.Resistance is chosen 5-10M, is indicator light with LED.An embodiment of the present utility model is: switch is fixed on the plug, on the plug that resistance and indicator light are also fixed.Switch has " conducting ", " cut-out " mark on plug.
The utility model also can all be fixed on switch, resistance and indicator light on one insulating base, and lead connects attaching plug and electric kettle socket respectively.
Indicator light does not work when cutting off as switch, and indication circuit access failure then needs the situation of check circuit, check that whole Socket for electric kettle and plug connect with supply socket could Closing Switch make kettle work after good.When cutting off the electricity supply, cut off earlier switch, represent when indicator light is bright that load excises, can relieved group remove plug.Can not produce electric spark.
Claims (3)
1, electric kettle attaching plug is characterized in that mains switch of serial connection on the on line of electric kettle plug.
2,, it is characterized in that at the mains switch two ends of an electric kettle plug resistance in parallel and an indicator light by the described electric kettle attaching plug of claim 1.
3,, it is characterized in that on the fixing plug of described mains switch, on the plug that resistance and indicator light are also fixed by the described electric kettle attaching plug of claim 1.
