Abstract
A device is disclosed for connecting control current lines in low voltage switchboard plants. The device should allow the control current in a plug-in distribution board to be easily maintained up to a test position of the rack and to be cut beyond this position when the rack is drawn out. The device has two multipoint plugs with plugs and sockets, of which the first is rigidly linked to the rack and the other is movably mounted over a limited path on two guiding pins, the terminal cross-section of which is enlarged. In the test position they are locked in by elastic elements, ensuring complete contact between both multipoint plugs in this position when the rack is inserted. A plurality of control lines can be easily cabled with little attrition in a reduced space within a plug-in distribution board and a test position can be reached by drawing out the rack.
