Abstract
The utility model provides an automatic power -off cell phone charger, before the current input charges the input area, is provided with a power master switch including the input area and the output area that charges of charging, when this switch pulls out, takes part in quick -witted charger line end through the cell -phone, realizes the automatic control charger and inputs the switch of power. The utility model discloses reach following effect: save the life of electric energy, extension charger, prevent that the long -time work of charger from generating heat and arouse explosion, bad phenomenon emergence such as on fire.
Description
Technical field
For the technical field of mobile phone charging in this utility model daily life, relating to one need not pull up charger from socket, just can automatically cut off a kind of charger of charger input power.
Background technology
People are when charging the phone, because smart mobile phone charging times is relatively more frequent at present, after majority like charging complete, directly mobile phone is extracted, and charger is also stayed in supply socket, in running order, electric energy wasted by charger always, it is also easy to cause charger aging, excessive heating, even blast causes fire, and somebody goes away, a lot of skies allow charger stay to work on power supply especially, and potential safety hazard is especially prominent.
Summary of the invention
For meeting majority's charger complete use habit being also reluctant to extract power supply of charging, solving above bad phenomenon, this utility model reaches following effect: first, energy saving, and second, extend the charger life-span, the 3rd, get rid of potential safety hazard, safe charging.Its embodiment is as follows:
One automatically powers off charger for mobile phone, including charging input area (1), charging output area (2), battery of mobile phone (13), battery live wire plug (14), battery zero line plug (18), and some wires of being correlated with, the upper section lead (8) of input electricity, input electricity epimere plug (10), input electricity epimere jack (11), input electricity epimere contact (16), insulator button (15), input electricity hypomere contact (20), input electricity hypomere plug (9), input electricity hypomere jack (7), output electricity live blade (17), output electricity neutral blade (19), mobile phone (12).
As further embodiment:
nullOne automatically powers off charger for mobile phone，Including charging input area (1)、Charging output area (2)、Battery of mobile phone (13)、Battery live wire plug (14)、Battery zero line plug (18)、And some wires of connection of being correlated with，It is characterized in that，The upper section lead (8) of input electricity is uniquely connected from positive source，Input electricity epimere plug (10) and input electricity epimere jack (11) serial communication，The other end of input electricity epimere jack (11) place wire is provided with input electricity epimere contact (16)，Input electricity epimere contact (16) is provided above with the insulator button (15) that can not conduct electricity，Input electricity epimere contact (16) and input electricity hypomere contact (20) form touching formula switch，Output electricity live blade (17) being fixed on charger forms touching formula switch with output electricity neutral blade (19) Tong Bu battery live wire joint (14) above set with mobile phone (12) and battery zero line joint (18) respectively，Input electricity hypomere contact (20) is connected serially to charging input area (1) with input electricity hypomere plug (9) and input electricity hypomere jack (7) respectively.
Described automatically powers off charger for mobile phone, it is characterized in that, input electricity epimere contact (16) and input electricity hypomere contact (20) form touching formula switch, output electricity live blade (17) and battery live wire joint (14) form touching formula switch, output electricity neutral blade (19) and battery zero line joint (18) form touching formula switch, and above three groups of switches synchronize to disconnect or synchronizing close.
Described automatically powers off charger for mobile phone, it is characterized in that, insulator button (15) is arranged in input electricity epimere contact (16), and fix on charger contacts when being embedded in charger with mobile phone (12) charging connection with the electric live blade (17) of output, output electricity neutral blade (19) and input electricity hypomere contact (20), battery live wire plug (14) is fixing with battery zero line joint (18) to be embedded on mobile phone (12).
This using method automatically powering off charger for mobile phone is as follows:
Connect 220V power supply and charger is inserted socket, when at this moment connecting the electric current arrival input electricity epimere contact of positive source wire, contact is off, input upper (lower) section of plug of electricity is all communicated to input upper (lower) section of jack of electricity, also output electricity fire (zero) line plug is all communicated to output electricity fire (zero) line jack simultaneously.When battery of mobile phone fire (zero) plug is entirely insertable connection charger charging end, not only connect output current of charger and form loop with battery of mobile phone, push switch by synchronizing simultaneously, connect positive source, such charger and mobile phone define complete charge circuit, start to charge for mobile phone.When charger is extracted from mobile phone, input electricity epimere contact elastic reaction disconnects and the connection of input electricity hypomere contact, and positive source is off, and namely charger need not be extracted power supply, after mobile phone extracted by charger, the power supply of charger is automatically cut-off.This utility model simple in construction, it is only necessary to add the input of polygon control survey power supply, just can realize energy-conservation and safety utilization of electric power of charging, and is suitable for large-scale popularization to various charger field.
Accompanying drawing explanation
Fig. 1 is the electrical block diagram before this utility model charger does not connect with mobile phone；Fig. 2 is the electrical block diagram after this utility model charger connects charging with mobile phone.
Detailed description of the invention
In conjunction with accompanying drawing 1-2, the utility model is described in further detail:
As shown in the figure, one automatically powers off charger for mobile phone, positive pole at power supply connects a unique wire (8), connect with input electricity epimere jack (11) by inputting electricity epimere plug (10), electric current arrives input electricity epimere contact (16) and forms push switch with input electricity hypomere contact (20), when mobile phone (12) connects with charger incoming end, connected light source of charger positive pole simultaneously, while making charger charging circuit Guan Bi, charger current is transported to battery of mobile phone (13), when mobile phone (12) is extracted from charger, input electricity epimere contact (16) has when returning elastically previous status, cut off the electric current of light source of charger positive pole, realize automatic power-off function of charger.
