Abstract
Abstract An electrical connection device for electrically operated components of heaters, especially vehicle heaters, in which block-shaped plug parts are molded on the lines coming from the components. The block-shaped plug parts are grouped side-by-side into a unit and a cap is attached to this unit. The cap has connection parts which are designed to be complementary to connection parts of the block-shaped plug parts so that a plug-in electrical connection is formed when the cap is mounted to the unit. Accoding to a preferred embodiment, the block-shaped plug parts are placed directly on the outside of a housing of a heater and they are connected with each other to form the unit with the help of interlocking connections and the cap. In another embodiment, the block-shaped plug parts are grouped into a unit and held together by a support having a pocket for each block-shaped plug part which is fastened to the heater by a holder.
