Abstract: The cylindrical plug of a low-voltage, high current capacity connector assembly has an axially positioned sleeve wiping contact and a transversely positioned U-shaped channel member to provide two pairs of planar wiping contact surfaces parallel to the plug axis and substantially perpendicular to the plug housing surface. The socket component, which will accept standard low-voltage, low current car appliance plugs, includes an internally mounted, closed face pin contact and a barrel contact having depending ears positioned to engage the protruding sides of the plug U-shaped channel member. The socket also has an internal boss and housing lip to prevent electrical activation of a standard automotive cigarette lighter plug, and the plug component of the connector assembly has the sleeve contact recessed to prevent contact following insertion into a conventional cigarette lighter socket.

Abstract: A mobile power tool and appliance operating system includes a portable lead-acid battery pack having a high current capacity socket compatible with existing low current plugs used with appliances intended to operate from automotive cigarette lighter sockets. Matable high current capacity plugs are attached to power tools and appliances through retractable cords. The battery pack is receivable in a 120 VAC powered charging base having a self-contained charging circuit including a transformer and a voltage regulator. The high current socket housing prevents inadvertent operation with an automotive cigarette lighter plug, and the high current plug housing prevents electrical contact in a automotive cigarette lighter socket, for safety reasons. In another embodiment, the battery pack is provided with two sockets for delivering different power outputs at each respective socket. Recharging of the battery pack can also be accomplished via connection made to one of the sockets.

Abstract: An automobile solar powered rechargeable battery-operated utility light comprises a housing, a light bulb, and a rechargeable battery. A solar panel is exposed through a housing wall for receiving solar radiation and generating a charge current for the battery. A bracket supports the light housing with the solar panel facing an automobile windshield and is releasably attached to the housing and to a post for supporting the automobile rear view mirror. The light is located at an optimum position for reception of incoming solar radiation and at a convenient location for removal for use.
