Abstract
A charger for batteries includes a housing having an open portion through which batteries to be charged are to be inserted. A constant tension spring within the housing urges the batteries outwardly of the housing. A cover is provided adjacent to the open portion of the housing, the cover being movably, pivotably supported on the housing. A pair of spaced-apart contact prongs are provided, at least one of which is carried by the movable cover, thereby preventing electrical connection to the prongs wherever the cover is moved away from the open portion of the housing. A latch arrangement retains the cover in a closed orientation. The batteries in the housing are retained therein by a portion of the latch whenever the cover is pivoted away from the open portion of the housing. One of the contact prongs is carried by the cover and moves therewith. A solid-state charging circuit within the housing is connected to the other one of the contact prongs. The charging circuit is an integrated circuit disposed against an extension of the other one of the contact prongs, thereby utilizing the other contact prong as a heat sink.
