ABSTRACT:
A connector assembly for rechargeable battery-operated power supplies requiring a watertight housing. Such a connector is usable, for example, in conjunction with a waterproof housing for a hand-carried, rechargeable floodlight. The connector assembly incorporates a male connector member affixed to the exterior of the housing for mating with a female connector via which power may be supplied to recharge a battery maintained within the housing. Vents which permit gases generated by the charging operation to escape from the housing are located interior to the periphery of said connector assembly. When the battery is not being recharged, the connector assembly is covered by a watertight cap, thereby closing the vents and protecting the male connector member. A pilot lamp charge indicator is provided, and the cap provides protection against injury thereto.
