ABSTRACT:
CLAIM OF PRIORITY
This application makes reference to and claims all benefits accruing under 35 U.S.C. Section 119 from an application entitled “FLEXIBLE BATTERY CHARGER ADAPTABLE TO THE BATTERIES OF THE MOBILE PHONE OF DIFFERENT SIZE” filed in the Korean Industrial Property Office on Jan. 17, 2000 and there duly assigned Ser. No. 2000-1969.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a desktop charger for charging a battery pack of a mobile phone. More particularly, the present invention relates to a flexible battery charger being adaptable for retaining different battery sizes.
2. Description of the Related Art
The conventional battery charger of a mobile phone is usually provided with two kinds of battery charging grooves, one of which is used for charging the mobile phone with a battery pack attached thereto and the other for charging a detached battery.
FIGS. 1 and 2
illustrate a perspective view and a cross sectional view of a conventional battery charger, respectively, wherein the battery charger includes a casing made of an upper casing frame
100
and a lower casing frame
200
, a plurality of charging terminals
310
for contacting a battery pack
410
, and a printed circuit board (PCB)
300
connected to the terminal contact element
310
.
The upper casing frame
100
is provided with a first charging groove
110
for charging the battery pack
410
mounted on the mobile phone
400
, and a second charging groove
120
for charging a detached battery pack. The charging terminals
310
are designed to partly protrude from the bottom surface of the charging grooves
110
and
120
for charging the battery packs. The frame
100
is also provided with at least one indication lamp
130
to notify the completion of the battery charge.
However, the second groove used for retaining the detachable battery in the conventional battery charger is fixed, thus fits only one type of battery pack. Hence, the conventional charger may not be used for charging other battery packs having different sizes. Currently, the size of a mobile telephone and its battery is becoming smaller and comes in different sizes and shapes. Thus, it is foreseeable that it would a waste of money and inconvenient for the users to purchase different battery chargers each time a new phone with smaller battery becomes available in the market.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a flexible battery charger, which may be adaptable and compatible for use with the mobile phone having various battery sizes.
In one aspect of the present invention, a mobile battery charger of for retaining and charging different battery packs is provided. The charger includes an upper casing frame provided with a charging groove for charging a detached battery pack, and a lower casing frame coupled to the upper casing frame for holding a printed circuit board therein, and a moveable support plate disposed between the upper casing frame and the lower casing frame being adaptable to receive different sizes of battery packs.
A more complete understanding of the apparatus of the present invention may be had by reference to the following detailed description when taken in conjunction with the accompanying drawings wherein:
