Abstract: There is a connection between on the one hand an electrical power lead made as a metal-clad cable with at least one electrical inner conductor electrically insulated from the metal shroud by a mineral and on the other a device to be electrically connected thereto, especially an electrically heatable catalytic converter, the inner conductor and the device being connected to one another via a detachable terminal connection, one part of which being located on the device and its other part being provided on the free end of the power lead.

Abstract: An electrically heatable starter catalytic converter (5) has a metallic housing (6) in which is arranged the actual catalyst (7) exposed to the exhaust gas flow, an electric resistance heating (8) and an electric connection line (10) that enters the housing (6) through an opening (9). The invention is characterized in that the electric connection line (10) is a metal-clad cable with at least one inner lead (11) electrically insulated from the metal cladding by a mineral (13). The inner lead (11) frictionally engages the electric resistance heating (8), and the metal cladding (12) enters the metallic housing (6) through the opening (9) and is welded or soldered to the edge of the opening (9) in a gas-tight manner.

Abstract: An electrically conductive connection is made between a metal connector and a metal layer applied and bonded by sintering to a ceramic substrate comprising glass and/or vitreous ceramic in small quantities. An adhesion-promoting layer having a glass and/or vitreous ceramic and metal particles is applied and bonded by fusion to the ceramic substrate. The metal layer with the sintered bond is then applied to the ceramic substrate and the connector is welded to the metal layer by laser welding.
