Abstract
Abstract An exterior power supply connection for supplying electrical power from a permanent power source to the interior of a recreation vehicle is adapted to be mounted in aligned openings in the walls of the vehicle, with a faceplate inside the vehicle and a slanted rainproof shield outside the vehicle. A pair of slots in opposite lateral walls of the adapter receive the outer shell of the vehicle and a clamping frame. A fastener between the frame and the shield causes the frame and the faceplate to bear tightly on the vehicle walls to secure the supply connection in place. A female receptacle mounted in the faceplate faces the interior of the vehicle, and a male receptacle disposed in a compartment located under the shield faces the outside. A slanted, downwardly opening coverplate is spring biased to cover the male receptacle. In use, a connector on a cord from the power supply is connected with the male receptacle in the compartment to supply power through the female receptacle to the interior of the vehicle.

Claim 1
Independent Claim
182 words
An exterior power supply connection for supplying electrical power from an external power source to the interior of a recreation vehicle or the like comprising: a. a housing adapted to be mounted in the vehicle having: i. a faceplate for disposition within the interior of the vehicle; ii. a pair of sidewalls extending from the faceplate for partial disposition outside the vehicle; and iii. an upper wall extending from the faceplate and capping the sidewalls, the upper wall being at an acute angle to the faceplate and extending downwardly from the top thereof for partial disposition outside the vehicle to facilitate the shedding of water; b. first electrical receptacle means in the faceplate for providing an electrical connection with an appliance within the vehicle; c. second electrical receptacle means within the housing below the upper wall and above the lower terminus of the sidewalls, the second receptacle means being disposed for disposition outside the vehicle for providing an electrical connection with the external power source; and d. electrical conductor means establishing a circuit connection between the first and second electrical receptacle means.
