Abstract

A charging device for mobile phone includes a main body; a rotatable pin-rotating member having two pins connected thereto for leading in alternating current; a contact conduction mechanism located between the pin-rotating member and a circuit board in the main body to conduct alternating current from the pins to the circuit board; a mobile phone rest base for a mobile phone to engage therewith and be charged; and battery contacts for a 9V battery to connect thereto. The contact conduction mechanism includes an annular seat having multiple contacts provided thereon, a pair of conducting strips, a turnable disc, and a pair of pin contactors sequentially fixed to a front side of the circuit board to align and associate with the pin-rotating member, so that AC power is led in via the pins to the circuit board even when the pin-rotating member is turned.

Claims

1. A charging device for a mobile phone, comprising:

a main body defining an internal space for receiving a circuit board therein, said main body being provided at a predetermined position with an opening;

a pin-rotating member being rotatably associated with said main body at said opening;

a pair of pins pivotally connected at inner ends to said pin-rotating member for leading in an alternating current from a power source receptacle to said charging device;

a contact conduction mechanism located between said pin-rotating member and said circuit board in said main body to enable the alternating current to be conducted from said pins to said circuit board even when said pin-rotating member is turned relative to said main body; and

a mobile phone rest base provided at a predetermined position on said main body and including a mobile phone connector, said mobile phone connector electrically connecting a mobile phone engaged with said mobile phone rest base to said circuit board, so that said mobile phone is charged.

2. The charging device for mobile phone as claimed in claim 1, wherein said contact conduction mechanism comprises:

an annular seat fixed to said circuit board and having a plurality of conducting contacts provided thereon;

a turnable disc fixed to said circuit board to locate in front of the annular seat and align with said opening on said main body;

a pair of pin contactors fixed to a front side of said turnable disc corresponding to said two pins; and

a pair of conducting strips fixed to said turnable disc opposite to said pair of pin contactors to correspond to said annular seat.

3. The charging device for mobile phone as claimed in claim 1, wherein said main body is provided at a bottom with downward projected battery contacts, with which a battery can be correspondingly engaged.

4. The charging device for mobile phone as claimed in claim 3, wherein said battery contacts are adapted to engage with a rectangular 9V battery.

5. The charging device for mobile phone as claimed in claim 1, wherein said main body is provided at a top with a removable protective cap.

6. The charging device for mobile phone as claimed in claim 1, wherein said pair of pins are adapted to couple with at least one differently structured plug for plugging said charging device to differently structured AC power receptacles.
