Abstract

See full text

A method for the electrical insulation of an arrangement with an electrical functional element, such as a PTC element or a thermoelectric functional element is proposed, which is placed on a fastening part or in an electrically conductive casing. The inventive method is characterized in that the functional element together with the at least one connection, accompanied by the hollowing out of at least one contact surface to the fastening part, is so surrounded with an electrically insulating material that the latter engages on the fastening part or in the casing all around the contact surface. Thus, in a design and manufacturing simple manner, e.g. by extrusion, a comprehensive sealing of the electrical functional element can be achieved, so that during a subsequent covering with a material having a certain electrical conductivity, no shorting links are formed between the electrical connections of the functional element and the reference potential.
