Module device for a camera system, retaining spring device and corresponding camera system

A camera system for a motor vehicle, comprising

• a module device for the camera system, including:
• a housing device having an inner opening to allow an adjustment of an installation position of the module device in the motor vehicle;
• a sensor holder device, which has an upper region and a base region and is coupled to the housing device via at least one support element and to accommodate an image sensor;
• a lens apparatus, which is coupled to an interior surface of the sensor holder device in the upper region via at least one portion of the lens apparatus forming a connection element, and is set up to generate an optical image on the image sensor;
• and
• a retaining spring device which is coupled to an exterior surface of the base region of the sensor holder device and configured to press the image sensor with the heat-conducting intermediate layer against the base region of the sensor holder device by a spring force and to thereby form a heat-conduction path across the heat-conducting intermediate layer;
• a camera electronics system for signal conversion, the camera electronics system being integrated on a main board, coupled to the image sensor of the module device to convert signals received from the image sensor into image information;
• and
• a camera housing to accommodate the module device and the main board and which includes an adjustment recess, to accommodate the retaining spring device and to fixate the module device within the camera housing,
• wherein the retaining spring device consists of at least one of a flat spring, a leaf spring, a form spring, and a bent wire part,
• wherein the retaining spring device is configured to generate a contact pressure which presses the sensor holder device against the housing device.
