Patent ID: 11539259

Abstract:
The invention relates to a contact device (1) for a stator (2) of an electric machine, wherein the contact device (1) has a contact carrier (4) made from an electrically insulating material, an upper side, which can be positioned to face away from the stator (2), and, at least on the upper side which can be positioned to face away from the stator (2), electrically conductive connection conductors (41) for contacting a plurality of coils (3), arranged over the circumference of the stator (2), via coil conductors (31). The contact device (1) furthermore has feedthrough openings (5), through which the coil conductors (31) of the coils (3) can be guided such that at least one coil conductor (31) can be connected to a connection conductor (41). The contact carrier (4) moreover has fixing devices (6) at the feedthrough openings (5), which fixing devices are designed in such a way that at least one coil conductor (31) touches a connection conductor (41) at a contact surface (7) and the coil conductor (31), at this contact surface (7), applies a permanent force action to the connection conductor (41) via forces acting perpendicularly to the respective conductor axis, whereby mutually parallel-lying portions of the coil conductor (31) and the connection conductor (41) are pressed against each other at the common contact surface (7).
