ABSTRACT:
In the connecting device for the electrical and mechanical connection of component conductors and for the supply or removal of the coolant to or from the hollow conductors (5) of the stator winding bars (3) of electrical machines, the hollow conductors (5) and, optionally, the solid conductors (4) of the winding bar in the winding head are held together in a metallic component (7). This component is connected to a water chamber (2) which is in turn provided with connecting fittings (6, 11) for the supply or removal of the coolant and is surrounded by an insulating jacket (10).
Hitherto the production and assembly of said insulating jackets was very time-consuming. In order to shorten the assembly time, the insulating jacket comprises a preferably U-shaped insulating part (10) which is pushed over the metallic component (7), the water chamber (2) and the connecting fittings (6, 11) from the inside and overlaps the latter radially. Means (17, 19 and 12a, 12b) for filling the spaces between the metallic component and the U-shaped insulating part (7) and between the connecting fittings and the U-shaped insulating part are provided both in the region of the metallic component and in the region of the connecting fittings, which means also provide for a firm retention of the insulating jacket.
