Abstract
The utility model discloses a time control power supply adaptor, which comprises a connecting terminal which is connected with external alternating current power supply, wherein, an electric appliance connecting terminal is connected with the connecting terminal; a timer is arranged in a time control device which is connected between the two ends. The utility model has the advantages of convenience, money saving, economy and material benefit. The actual use range of appliances is expanded, and the electrically safety in the course of the operation of the appliances is enhanced.
Description
The utility model relates to technical field of electricity, is a kind of switching device, specifically, is a kind of time control switch device.
Some often take place in daily life because of using household electrical appliance improper, and the trouble that causes is so that contingency.As: see TV winter in bed, some TV remote controller can only direct current shutdown and can not ac dump, for relieved and safe for the purpose of, also to leave the bed and turn off power supply.Opening electric fan sleep summer, closing and disliking heat, opening and be afraid of to catch a cold, be preferably in and turn off automatically after just sleeping.But some electric fan household electrical appliances does not have timing function.Some are careless and use the people of the household electrical appliance that the evolution of heat is arranged in anxiety is busy, and forgotten the pass power supply or leave the scene for some reason and will breed disaster a period of time.
The purpose of this utility model provides the time control power supply changeover device of a kind of practicality that can expand household electrical appliances, convenience, fail safe.
Technical solution of the present utility model is: a kind of time control power-supply adapter, it is characterized in that: a link that joins with external ac power source is arranged, what link to each other with this link is the electrical equipment link, between above-mentioned two ends, be connected to time controller spare, timer is arranged in the time controller spare.
The link that aforementioned and external ac power source described in the utility model is joined and all adopt single phase alternating current (A.C.) three-terminal polarized plus plug or three sockets with the electrical equipment link.Between two tie points of time controller spare and main line, be connected to and be connected switch.A timer is arranged in time controller spare, its normally opened contact is arranged between the connecting line of timer and main line.Aforementioned have one or more with three sockets electrical equipment link.
The utility model has the advantages that: make things convenient for, save money, expanded the actual scope of application of household electrical appliances, improved the electrical safety in the household electrical appliances use, both economical, material benefit again.Can reduce because of the careless and inadvertent fire that causes and the generation of contingency.Reduce the unnecessary life and the loss of property.Removed and forgotten to close power supply for the moment or left use heating household electrical appliance scene for some reason and the trouble and worry of generation accident.Be exactly that you have forgotten the pass power supply, the utility model also can be cut off the electricity supply automatically, can not make mistakes because of heat accumulation.
Below in conjunction with accompanying drawing and enforcement side the utility model is further described:
Accompanying drawing has been described an embodiment of the present utility model.In this embodiment, empty frame A is a single phase alternating current (A.C.) 220V three-terminal polarized plus plug, and L is a phase line, and N is a zero line, and E is a ground connection.Above as a link that joins with external ac power source, empty frame B is a time controller spare, and K2 is a normally opened contact, and S is a timer.K2 promptly closes when the S setting-up time; The S setting-up time is automatic disjunction to K2.Empty frame C is three sockets of 220V single phase alternating current (A.C.), in order to express, has omitted several three or two sockets, and they are relations in parallel with interior three sockets of empty frame.L is a phase line, and N is a zero line, and E is a ground connection.R is fuse (being fusible link), and solid line is a lead, and K1 is a time control power supply changeover device switch.
Using method: A frame plug is inserted three sockets of alternating current 220V.The C frame is inserted electrical appliance.When needing to use timer, the disconnection K1 setting S time gets final product.AC dump then.Also can work as the common power transducer and use, promptly not set the S time.The K1 that closes gets final product.If at this moment need timing again then elder generation's setting S time.Disconnected again K1 switch.So just need not shut down and change.Adopt said structure, though be mechanical structure, good reliability, simple and easy, cost is low, time can be done length, can accomplish that general breaking current was about 2 amperes 1 hour, two hours or longer, but, can improve breaking current ability to 5 ampere even higher through improving.And the power of 5 Ampere currents can reach (alternating current 220V) about 1100W, and general household electrical appliances are all under this power.
Claims (5)
1, a kind of time control power-supply adapter, it is characterized in that: a link that joins with external ac power source is arranged, and what link to each other with this link is the electrical equipment link, is connected to time controller spare between above-mentioned two ends, and timer is arranged in the time controller spare.
2, time according to claim 1 control power-supply adapter is characterized in that: the link that aforementioned and external ac power source are joined and all adopt single phase alternating current (A.C.) three-terminal polarized plus plug or three sockets with the electrical equipment link.
3, time according to claim 1 and 2 control power-supply adapter is characterized in that: be connected between two tie points of time controller spare and main line and be connected switch.
Valve control power-supply adapter is characterized in that: a timer is arranged in time controller spare, its normally opened contact is arranged between the connecting line of timer and main line when 4, according to claim 1 and 2.
5, time control power-supply adapter according to claim 1 and 2, it is characterized in that: aforementioned have one or more with three sockets electrical equipment link.
