ABSTRACT:
In an assembly of at least two electrodes which are connected together in an insulating manner, said electrodes are kept at a given distance from each other by at least one member of an electrically insulating material situated between the electrodes which comprises a core which determines the distance between the electrodes and a jacket which directly adheres to the electrode material by heating. The material of the core has a higher melting point than the material of the jacket so that the core during effecting a connection between the jacket and the electrode material maintains its shape.
