Abstract: An arrangement allows the end of an electrical conductor (2) to be secured by clamping by a spring leaf (9) against a conductive connecting wall (6) in a compartment of a case of insulating material into which the end of the conductor is inserted. Arrangement includes at least one pushable member (10) for compressing the spring leaf, which penetrates the compartment in which the leaf is located and which is maneuverable from the outside of the case between two positions, one in which the spring leaf is relaxed and allows the end of a conductor to be freely inserted, the other in which the spring leaf is flexed by the urging of the pushing member and bears against the connecting wall.

Abstract: The invention comes within the field of static converters.A static converter which comprises two Graetz rectifier bridges connected together at their DC terminals by first and second connections. One of the bridges is connected to the AC mains by means of a transformer and the other is connected to a variable speed synchronous machine. A third connection links the neutral conductor of the stator winding of the synchronous machine to the neutral conductor of the secondary winding of the transformer. Control means of the rectifier connected to the mains provide independent control for the upper half-bridge and the lower half-bridge of the rectifier.
