Actuating drive having an electrical plug-in connection

The invention relates to an actuating drive, comprising a housing, which has a first housing part and a second housing part, wherein the two housing parts each have an edge, each edge having an end face, and wherein the two end faces face each other when the two housing parts are joined, wherein the first housing part and the second housing part can be detachably joined, wherein the actuating drive is designed to accommodate an exchangeable connection module for a cable feed, wherein the exchangeable connection module can be inserted into an opening of the first edge of the first housing part and wherein the exchangeable connection module can be connected in a form-closed manner to the end faces of the edges in a region of the opening when the two housing parts are joined. Thus, an actuating drive, in particular for ventilation flaps or fire dampers, having high flexibility in the electrical connection contacting is provided.
