Abstract
Fluid connection device, in particular for a motor vehicle, includes a female nozzle having an internal fluid flow passage, and being configured to receive a male nozzle. A sensor senses that the male nozzle is received within the female nozzle, and an electrical plug electrically connects the sensor to an electrical power source. The sensor includes a flexible, electrically conductive dome located within the female nozzle. In a first position, the dome has a generally curved shape. When the male nozzle is inserted into the female nozzle, the male nozzle presses the dome to deform the dome into a second position. In the second position, the dome has a generally flattened shape and provides an electrical connection between two terminals connected to the electrical.
