Patent ID: 7557533

Claim:
A nickel metal hydride/nickel cadmium secondary battery charger, comprising: a) a charging base including a lower casing and a cover, wherein the lower casing has a containing space, and a front section of the containing space has a U-shape retaining base, and the cover has a recessed space defining a battery compartment, and both front and rear walls of the battery compartment have front and rear hollow portions respectively, and a central position of a front edge of the cover has a pivotal groove formed through a front wall of the battery compartment to an exterior; b) a charge control circuit board installed in the containing space of the lower casing, and having a first set of conductive reeds disposed at its front end and a second set of conductive reeds disposed at its rear end, wherein the first set of reeds is protruded from the front hollow portion of the battery compartment into the recessed space, and the second set of reeds is protruded from the rear hollow portion into the recessed space, for respective electrical coupling to secondary batteries disposed in the battery compartment; and c) a power supply plug corresponding to a cylindrical shape of a cigarette lighter socket in a car, for inserting a distal end thereof into a cigarette lighter socket for connecting to a power supply, and a proximal end forming a protruding ear, an axle extending from each of opposing sides of the protruding ear being pivotally coupled to the U-shaped retaining base of the lower casing, and one of the axles being provided for passing a conducting wire and connecting a power supply input terminal of the charge control circuit board, and the protruding ear being disposed in the pivotal groove and the two protruding axles of the protruding ear forming a rotational axis of the power supply plug, the power supply plug being pivotable about the axis through 180 degrees, the power supply plug thereby being pivotable from a position protruding from a front of the charging base to a storage position disposed in the recessed space defining the battery compartment.
