Abstract
This creation is a kind of "AC/DC rechargeable mobile phone cell". A charger is installed in a case which is composed of a panel and a back case body. The panel has a concave cabinet which can hold an eversible and locatable plug plastic body. It makes the back end of the plug's electric insertion piece pressing on the elastic conducting piece closely.
Consequently, the conducting quality~is improved. A dual-color LED and the rechargeable cells are connected across the charging circuit. When the charging voltage is lower than reference voltage, the red light of the dual LED is lighten. When the cells are fully charged, the green light of the dual LED is lighten and a low potential is output to an optic-coupling switch from a linear IC to stop charging. And then, the energy is saved and the cell's life is prolonged

Description
Explanations on the Creation:
Background of the Creation:
[A Brief Introduction on the Creation Technology]
This creation is a kind of "AC/DC rechargeable mobile phone cell", especially a mobile phone cell which can be charged directly by market power or charged by an ordinary DC charger available on the market.
To charge a traditional mobile phone cell for replenishing the consumed energy a charger must be used. For this reason, ~e user has to buy an extra charger and pay more money. Besides, the charger is too large and too heavy and cumbersome to carry.
[A Brief Introduction on Former Technology]
Because of these disadvantages, the manufacturers have improved it. As shown in Fig.l, the rechargeable cell~'is composed of a case(10) and a charger etc.. A concave cabinet (13) with two notches on its lefr and right is placed on the panel ( 12) o ' the case ( 10) to hold an eversible and locatable plug (15). The plug(15) has two forward stretched electric insertion pieces(16) and a conducting support axle(17) connecting the electric insertion pieces(16) traverse. Left and right conducting plates(18) with notches are installed an the circuit board(11 ) of the, charger to grip the conducting support axle(17) of the plug (15). Then the market power(AC) can be supplied into the charger through the electric insertion pieces( 16), conducting support axle( 17) and conducting plate(18) of the plug(15). But this design of the conducting support axle(17) will increase current resistance; in addition, the contac's between the conducting support axle(17) and the conducting plates(18} of the circuit board(11) is in fast coupling form, which cannot be firmly contacted Besides, when the plug(15) is everting and locating as well as retracting and settling, the conducting support axle(I7) is not detached from the conducting plate(18), it always courses abrasion and result in lowering conductivity. Even more, because the positioning of the conducting support axle( 17) of the plug ( 15) is based on the firm assembly of the circuit board( 11 ) and the supporting of the conducting plate(18), looses always occur. This is not an ideal structure for operation.
Another shortcoming is: Plug(15) is the AC input terminal of the charger.
After rectifying, filtering and stabilizing, the AC is converted into DC to drive the transformer and charging circuit through a driving circuit composed of transistors. The DC, on the one hand, is used to charge the rechargeable cell(19), on the other hand, supplies energy to the mobile phone through the DC
output terminals of the panel(12). When the cells(19) are full charged, the charger cannot shut down the driven circuit automatically. It will result in energy wasting and life-time shortening of the circuit and cells(19). Another problem is that there is no indicator for full charging and no overheating protection for the cells(19).
Because of the disadvantages of the existed rechargeable mobile phone cell, I
have been looking for a new way to solve these problems and finally completed the creation "AC/DC
rechargeable mobile phone cell".
The purpose of this creation is to provide an "AC/DC rechargeable mobile phone cell". Its plastic axle of the plug is held between the concave cabinet of the panel and back case body, making plug's electric insertion piece to press closely on the elastic conducting pieces of the charger circuit board. When the plug is retracted and settled, the electric insertion pieces will be detached from the elastic conducting pieces. It can be fast and firmly assembled as a whole. It is durable and its conducting quality is improved.
Another purpose of this creation is to provide'an "AC/DC rechargeable mobile phone cell". An eversible and locatable plug is placed on the back of the case body, making the rechargeable cell can be directly charged by the market power without detaching from the mobile phone.
The third purpose of the creation is to provide an "AC/DC rechargeable mobile phone cell". A
dual-color LED, a thermal sensitive resistor and the rechargeable cells are connected parallel across the charging circuit. When the charging voltage is lower then the reference voltage, the red light of ~e dual LED is lit up. When the cells are fully charged, the green light of the dual LED is Iit up and a low potential is output to an optic_coupling switch from a linear IC to stop recharging.
Accordingly, the energy is saved and the cell's life is prolonged.
For the purpose of appraisal, a practical example with pictures is introduced in detail as follows to explain how to realize the above target by using technology measures.

A pair of plastic supporting pIates(26x27) are placed on the inner side of the back case body oppositely each other with one an the left, the other on the right. The plastic supporting plates grip the supporting axle(32x33) of the plug with their notches(28) located at the front end of the plates to enable the plug(30) can be evened and located ar retracted and settled around the axle.
The charger circuit board(50) and rechargeable cells(67) are firmly installed in the case of the rechargeable cell. Two elastic conducting pieces(51)(52) stretch out of the circuit board (50) are used as AC input terminals. The rear ends of the electric insertion pieces(34)(35) of the plug(30) are elastically pressed on the pieces(51 )(52). Fig.4,5,6 show that the plug(30) is in everted and located position. The plastic body (31} of the plug (30)matches the left and right walls(23x24) of the concave cabinet(22). The plastic supporting axle(32)(33) is gripped and held by a supporting
3 plate(26)(27) and its notches(25)(28) with the same material. This method can reduce electrical resistance, improve current conducting quality as a result, the AC current can run into the charger through the electric insertion pieces(34)(35) of the plug(30) and elastic conducting pieces(51 X52) smoothly. In addition, it is durable and can be assembled fast and firmly.
As indicated in Fig.7, when the rechargeable cell needs not to be charged, you may retract and settle the plug(30) into the concave cabinet(22) space of the panel (20), then the rear ends of the electric insertion pieces(34)(35} of the plug(30) will detached from the elastic condu~ng pieces(51 x52) of the circuit board(50).
As indicated in Fig.B, AC110-240V power enters the AC input terminal(60) of the rechargeable cell, and then goes through the rectifying circuit(61), filtering circuit(62}
, voltage stabilizing circuit(63), driving circuit(64) and charging circuit(65) to charge the rechargeable cells(67). When using market charger, the charging current runs through the DC terminal(69) and elastic charging piece(42) ( as indicated in Fig.3) into rechargeable cells(67). When the rechargeable cells are fully charged, you may switch the DC into the mobile phone through its DC output terminal (68) and the conducting piece(40) as indicated in Fig.3.
Please refer to Fig. 9: The AC 110-240V power enters the AC input terminal{60) of the charger, then rectified into DC current through a bridge connected rectifier (D 1 ) of the rectifying circuit{61 ). The current limiting resistor(Rl ) is used to limit the ciurent within a definitive range;
the resistor(R2) and diode(D2) combined with the transistor(Q1) are used as a filter, and together with a Zener diode(D3) in the voltage stabilizing circuit provide a comparing reference voltage for the over current protection seckion in the driving circuit.
A switching circuit , which provides a proper voltage to control the transistor(Q2), is composed of a transistor(Ql) and an optical coupler(E1). The rechargeable cells(67} are charged through the transformer(T) and charging circuit(65). The charging circuit(65) is connected to the output terminal of the transformer's secondary coil. The following elements are connected in the charging circuit(65) paralelly: a dual color LED, a capacitor(E4) serially connected with a diode{D4), and the rechargeable cells(67). Through a Zener diode (D5) and resistor (R7), a linear IC(EZ) is connected at the connecting point of the capacitor(C4) and diode(D4) to provide a reference voltage. Ano;her end of the linear IC(E2) is connected to the cross-over point of the dual color LED to compare the charging voltage with the reference voltage. While the voltage is lower than the reference voltage (tee potential of pin #3 lower than that of pin #2), the driving circuit(64) is driven to work, and the rechargeable cells(67) is charged through the transformer(T) and the charging circuit(65). At the same time, the dual color LED (refer to the light window(29) in Fig.3) is lit up with red color, showing it is charging. When the rechargeable cells are fully charged the potential of pin #2 lower than that of pin #3), the diode(D4) is conducted and the dual LED is lit up with green color. At the same time, a lower potential is output to the optical switch IC(E 1 ) from the linear IC(E2) to cut-off the transistor(Q2) and stop charging. As a result, the energy is saved and the life of the circuit and cells is prolonged.

As indicated in Fig.7, when the rechargeable cell needs not to be charged, you may retract and settle the plug(30) into the concave cabinet(22) space of the panel (20), then the rear ends of the electric insertion pieces(34)(35} of the plug(30) will detached from the elastic condu~ng pieces(51 x52) of the circuit board(50).
As indicated in Fig.B, AC110-240V power enters the AC input terminal(60) of the rechargeable cell, and then goes through the rectifying circuit(61), filtering circuit(62}
, voltage stabilizing circuit(63), driving circuit(64) and charging circuit(65) to charge the rechargeable cells(67). When using market charger, the charging current runs through the DC terminal(69) and elastic charging piece(42) ( as indicated in Fig.3) into rechargeable cells(67). When the rechargeable cells are fully charged, you may switch the DC into the mobile phone through its DC output terminal (68) and the conducting piece(40) as indicated in Fig.3.

4 secondary side, two thermal sensitive resistors (R10),(R11) of an over-heating protection circuit(66) are serially connected with it. While the temperature inside the rechargeable cell(67) is rising, the resistance of the thermal sensitive resistors (R10), (Rl 1 ) is going down correspondingly, which provides an over-heating protection to stop charging the rechargeable cells.
As indicated in Fig.lO, the concave cabinet(220) is placed on the back of the case(210) to hold the plug(30) making the rechargeable cell to be charged by the market power without detaching it from the mobile phone.
