Abstract: The present invention relates to an electric coupler for high-voltage DIN C type cells comprising a voltage divider, a condenser and two terminal contacts and wherein the condenser is elongated and its ends are in contact with the two terminals of the coupling device, occupying an axis parallel to the imaginary central axis of the connector passing through the two contacts and wherein the resistances of the divider are aligned and parallel to the mentioned axis of the zig-zag device. As a result of this arrangement the insulation can be assured and the field distributions of both systems are compatible with one another and with those of the DIN C connector.

Abstract: The present invention relates to a resistive voltage divider comprising a plurality n of resistive elements in a configuration wherein the angles m=n?1 between each pair of elements are between 180° and 10°, characterized in that the group of elements is supported by a dielectric the shape of which is such that it allows the creepage distance of the divider to be equal to or longer than the sum of creepage distances of the individual resistances. This arrangement allows a correct insulation of the device because it maintains the outer insulation since in the event of short-circuit the current will flow through the resistances and not through the support.
