Abstract

A charger compatible with different-sized rechargeable batteries of mobile telephones includes a body for charging the battery and an adapter optionally utilized to electrically connect the rechargeable battery with the body. In a preferred embodiment, the body is detachably mounted to an under face of the adapter and electrically connected with the adapter. The battery is detachably mounted to a top face of the adapter and electrically connected with the adapter. The adapter may have different configurations adaptable for different-sized mobile telephone batteries. In an alternative preferred embodiment, the battery is directly mounted to a surface of the body and electrically connected with the body. With this arrangement, expense for purchasing a different charger can be eliminated when a user attempts to use a second mobile telephone having a size different from that of a first mobile telephone, because only the adapter needs to be replaced and the first body can be re-used.

Claims

1. A charger compatible with different-sized rechargeable batteries of mobile telephones, comprising:

a body for charging a rechargeable battery; and

an adapter detachably mounted between the body and the rechargeable battery and electrically connecting the body with the rechargeable battery;

wherein said adapter includes;

a recess defined in a top face thereof, each of two opposed side walls defining the recess having a plurality of protrusions respectively extending therefrom to be receivably engaged with a plurality of corresponding slots defined in a bottom edge of each of two side walls of the rechargeable battery; and

a pair of extensions formed on a side wall of the recess proximate a first end of the adapter to be engaged with a pair of hook portions formed on two distal ends of a press portion formed on the rechargeable battery.

2. A charger compatible with different-sized rechargeable batteries of mobile telephones as claimed in claim 1, wherein said body has a plurality of spaced overhanging lips respectively extending from two sides of a top face thereof, adjacent overhanging lips defining a gap therebetween, said adapter has a plurality of spaced hooks respectively extending from two sides of an under face thereof to receivably engage with the respectively overhanging lips by aligning the hooks with the respective gaps of the body and then urging the hooks to receive the respective overhanging lips.

3. A charger compatible with different-sized rechargeable batteries of mobile telephones as claimed in claim 1, wherein said body has a cavity defined in a first end thereof and a hole defined near the cavity, said adapter has a latch portion integrally formed in a first end thereof, a top face of a first end of the latch portion having a press section corresponding to the cavity, a bottom face of a second end of the latch portion having a hook downwardly extending therefrom to be correspondingly received in the hole of the body.

4. A charger compatible with different-sized rechargeable batteries of mobile telephones as claimed in claim 1, wherein said adapter has a plurality of first connecting points formed on an under face thereof to electrically connect with a corresponding plurality of connecting points formed on the body, and a plurality of second connecting points formed on the surface thereof to electrically connect with a corresponding plurality of connecting points formed on the rechargeable battery.

5. A charger compatible with different-sized rechargeable batteries of mobile telephones as claimed in claim 1, wherein said adapter includes:

a projecting block formed on a top face thereof proximate a first end of the adapter, said projecting block defining an excavation at a side opposite to the first end of the adapter to receive a first end of the rechargeable battery; and

a recess defined in the top face thereof and proximate a second end of the adapter to receive a plate extending from an under face of the rechargeable battery, an distal-end wall defining said recess having a number of holes defined therein to correspondingly and receivable engage with a number of hooks formed on the plate of the rechargeable battery.

6. A charger compatible with different-sized rechargeable batteries of mobile telephones as claimed in claim 5, wherein said top face of the adapter further has a plurality of conductive posts formed thereon to be electrically connected with the corresponding connection points formed on the under face of the rechargeable battery.
