ABSTRACT:
The pole body contains an insulating carrier element made of plastic and provided with elevations on one side and on an other side of the insulating carrier element. The elevation on the other side partially protrudes into a metal layer applied to the insulating carrier element and conjointly therewith forms a planar surface forming the two poles of the fuze. The pole body is manufactured by applying the metal layer to the insulating carrier element which is provided with wedge-shaped elevations. Subsequently, the tips or ridges of the elevations are removed to such an extent that planes including the metal layer are formed. One of the elevations constitutes an interrupted elevation and a number of detonating bridges is formed, depending on the number of interruptions in the elevation between the ends of the elevation bounded by the interruptions thereof. The pole body is used in electric fuze devices which have a reaction time in the microsecond range and thus are suited for use with ammunition.
