Abstract

The invention discloses a handy battery charger comprising a body including upper and lower hollow cases that assemble together to form a receptacle for dry cells, said upper and lower cases having an opening at one end; a first connector with a plurality of connecting pins mounted on the opening, configured to be selectively connected to a second connector disposed at the bottom portion of a cellular phone to supply the output voltage from the dry cells to the cellular phone; a couple of resilient binding clips arranged at opposite ends of the first connector to prevent accidental release of the first connector from the second connector, wherein each of the resilient binding clips includes a hook at an upper end and a pivot axle part at a lower end, the hook having a protrusion extending in a direction to engage the second connector, said pivot axle part being bent in a direction perpendicular to the protrusion of the hook and disposed within a pivot groove formed in the body; and a plurality of positive and negative coil terminals to arrange the dry cells in series electrical connection and to supply the output voltage of the dry cells to the first connector, thereby providing the cellular phone with the dry cells in the recharged state at any time and achieving the cellular phone to be in a continuous use state.

Claims

1. Handy battery charger for cellular phones, comprising:

a body including upper and lower hollow cases that assemble together to form a receptacle for dry cells, said body having an opening at one end;

a first connector with a plurality of connecting pins mounted on the opening, configured to be selectively connected to a second connector disposed at a bottom portion of a cellular phone to supply output voltage from the dry cells to the cellular phone;

a couple of resilient binding clips arranged at opposite ends of the first connector to prevent accidental release of the first connector from the second connector, wherein each of the resilient binding clips includes a hook at an upper end and a pivot axle part at a lower end, the hook having a protrusion extending in a direction to engage the second connector, said pivot axle part being bent in a direction perpendicular to the protrusion of the hook and disposed within a pivot groove formed in the body; and

a plurality of positive and negative coil terminals to arrange the dry cells in series electrical connection and to supply the output voltage of the dry cells to the first connector.

2. The handy battery charger for cellular phones as claimed in claim 1, further comprising a cap sized and configured to cover and protect the first connector at a top end of the body, wherein the cap is removably attachable to the body.

3. The handy battery charger for cellular phones as claimed in claim 2, wherein the body further comprises a couple of inserting grooves formed at opposite ends of the body and wherein the cap further comprises a couple of projections formed on an interior surface of the cap to correspond to the inserting grooves, so that the cap may be removably attached to the body.

4. The handy battery charger for cellular phones as claimed in claim 2, wherein the cap includes a connecting string to the body.

5. The handy battery charger for cellular phones as claimed in claim 1, wherein a cap is made detachable to protect the first connector at a top end of the body, wherein a couple of inserting grooves are formed at opposite ends of the body and a couple of projections are formed interior of the cap to correspond to the inserting grooves, so that the cap maybe fixedly put on the body, and wherein the cap includes a connecting string attached to the body.
