Abstract: A transformer having a core and coil assembly which includes a pair of cores disposed side by side, the core members being of the squared "O" type formed of a plurality of nested, generally rectangular laminations. A space is provided between a pair of adjacent laminations in corresponding locations in each core, and a coil surrounds the adjacent sides of the respective cores through the central openings of the cores. Also included is a terminal board support having a pair of tabs to be inserted in the spaces between the adjacent laminations, the tabs being provided with holes having extruded edges for frictional engagement with the core laminations. The core and coil assembly is placed upon a flat base member and a U-shaped band is placed so as generally to encompass the top and two sides of the core and coil structure to make contact with a part of up-turned flanges of the base member.

Abstract: An electrical fuseholder for receiving an elongated, cylindrical fuse is provided with a pair of sheet-metal terminals which serve as means for connection into a circuit to be protected, as well as mechanical mounting means. The terminals are secured respectively between a pair of U-shaped fuseholder clips and an electrically insulating base and are provided with flanges for prevention of rotation of the respective terminals relative to the insulating base and of the U-shaped clips relative to the respective terminals.
