MECHANICALLY CODED MECHANISM INTENDED TO PREVENT A FALSE INSERTION OF A DETACHABLE MODULE INTO A SOCKET OF AN OVERVOLTAGE DEVICE SUBJECT TO VOLTAGE

摘要

The technical problem solved by the present invention is a constructional solution to a mechanically coded mechanism designed to prevent a false insertion of a detachable module into a base part of a surge protective device subject to voltage. The essence of the mechanically coded mechanism designed to prevent a false insertion of a detachable module into a base part of a surge protective device according to voltage lies in that the bottom of the base part intended for the arrangement of the detachable module is provided with vertical grooves, into which a coded combination of first pins is arranged according to the voltage, for which the detachable module is embodied. The housing of the detachable module [N2]is provided with grooves in the same verticals intended for the arrangement of a coded combination of second pins arranged on positions, in which there are no first pins in the base part.
