Field device with electronic module including cover

A process automation field device, comprising:

• an electronic module with a first electrical terminal;
• a first electrical plug with a cable clamp for receiving a cable core, wherein the first electrical plug is adapted to be detachably connected to the first electrical terminal of the electronic module;
• a cover with a clamping element;
• and
• a fastening device including a screw, a through-opening in the cover, and a thread in the electronic module for fastening the cover to the electronic module, wherein the screw comprises a threaded portion with an external thread between the screw tip and the screw head and a sliding portion located between the threaded portion and the screw head, wherein the screw has a smaller diameter in the sliding portion than in the threaded portion, and wherein the through-opening in the cover comprises an internal thread complementary to the external thread of the screw,
• wherein the cover is designed in such a way that when the cover is fastened to the electronic module by the fastening device and the first electrical plug is connected to the first electrical terminal of the electronic module, the cover, together with the electronic module, forms a first chamber and encloses the first electrical plug in the first chamber, and
• wherein the clamping element is arranged in such a way that the clamping element prevents the first electrical plug from detaching from the first electrical terminal of the electronic module.
