Abstract

In order to achieve improved mechanical properties for a coil (1), it is proposed to structure a first electroconductive winding (3) of the coil (1) as a coil former. This coil has a first connecting element (15), to which a second connecting element (17) is attached via an insulating part (25). The two connecting elements (15, 17) form the connections for the coil (1). In this way, a self-supporting coil structure is achieved. The coil (1) is particularly intended as an undervoltage winding with a low number of windings for cast resin transformers.
