19 Claims

1. A gear drive unit (10) comprising an electric drive motor (12), which has an armature shaft (16), and at least one housing part (14, 18), which accommodates the armature shaft (16), and an electronic interface (36) for accommodating different plug-in modules (34, 82, 94, 110) which can be inserted into the electronic interface (36) in the insertion direction (55), and the electronic interface (36) having walls (38) which are spaced apart from one another, with at least one first surface (50) and guides (64) being arranged on the walls (38) along the insertion direction (55) in order to seal off different plug-in modules (34, 82, 94, 110) from the at least one housing part (14, 18), characterized in that the walls (38) are approximately rectangular and form an opening (42) perpendicular to and an opening (44) axial to the armature shaft (16), and the openings 42 and 44 are connected to one another and form a common opening with radial and axial opening directions, the opening being substantially uninterrupted between the radial and axial opening directions, with the first surface (50) being formed by the inner surfaces (56) of the walls (38) in order to seal off the plug-in modules (34, 82, 94, 110) at least partially radially in relation to the insertion direction (55).
