Abstract
A water-cooled, high-current docking plug-connector device designed particularly for automatic welding machines has a plug socket component (1) with elastic contacts (4,6) and a plug pin component (2) for insertion into the socket component (1), so that the components can be rotated relative to each other. In order to transmit high current with low voltages, without the danger of the elastic contacts lifting out of position, several contact ring groups (3) are positioned in axial succession within the plug socket component (1), each of which ring groups (3) has at least one slotted outer socket contact ring (4) with a contact surface (5) resting elastically on the inner surface of the plug socket component (1), and at least one slotted inner socket contact ring (6) with a contact surface (7) which, in the inserted condition, rests elstically on the plug pin component (2). The outer socket contact ring and the inner socket contact ring of each contact ring group have mutually interfitting tapered contact surfaces (8,9).
