ABSTRACT:
The present invention relates to a contact maker for the gate terminal of power semiconductor components in disc cells and power semiconductor modules. Disposed above the power semiconductor component is a shaped member that incorporates in the region of the gate terminal a recess, and this recess, in turn, also incorporates a counter-support. The contact maker consists of a contact spring incorporating a pin-like extension at the end of the spring that contacts the gate terminal, and incorporating a connection created via a shaped metal element to a connecting cable for the external connection at the other end of the spring, and of an insulating sleeve with a contact spring disposed therein. The insulating sleeve itself has at least one locking projection, which, together with the counter-support of the shaped member, forms a snap-lock connection.
