Abstract: This specification discloses a module-type multi-function power outlet adapter for use of add-on electrical accessories in an automotive vehicle having a cigarette lighter socket. This device embodies a plurality of separate detachable modules which may be attached to a basic module insertable into the lighter socket and constructed to receive the additional modules, so to provide multiple electrical outputs. Such a module-type arrangement allows the adapter to fit the mounting space of cigarette light socket in various vehicles, boats, campers, and the like. A simple positioning pin structure ensures correct power leads connection and secures the combination between modules. The resulting solid structure allows easy reception for plug-in accessory equipment. In addition, this device acts as a power system protector by monitoring the voltage level and controlling the power use of those accessories no matter whether the engine is running or stopped.

Abstract: A connector apparatus for introducing video signals of an alternative video signal source to antenna terminals in the form of a pair of screw rods that are spaced apart from each other and provided on the back surface of a television receiver.The connector apparatus is provided with a housing, means for receiving the end of a coaxial cable extending from the alternative video signal source to introduce the outer conductor and the inner conductor of the coaxial into the housing, a pair of lead members comprising electric conductors and having free ends extending outwardly from the housing, and means for connecting one end of each of the lead members to the inner conductor and the outer conductor of the coaxial cable.

Abstract: A lithium-sulfur-dioxide battery (e.g., the BA5847/U) is modified so that can be used both in its customary manner or as a substitute for a standard Leclanche battery (e.g., the BA210/U). Since the aforementioned batteries typically have their connectors at different, distinct locations, the first-mentioned battery is provided with a second set of connectors (i.e., female sockets) which are located at the very same position as the connectors of the battery it may be substituted for. Thus, this battery has two sets of (2-hole) connectors and these are, in turn, interconnected in parallel.
