Housing for a field device of automation technology

A housing for a field device of automation technology, comprising:

• a first housing part with an external thread;
• and a second housing part with an internal thread, wherein:
• said external thread and said internal thread have a first screw thread type with a first thread side-form, said first screw thread type is embodied in such a manner that said external thread and said internal thread form a force interlocking, screwed connection, wherein the first screw thread type is a triangular or trapezoidal thread;
• said external thread and said internal thread are electrically conductive at least in corresponding portions of the surface;
• said external thread and/or said internal thread have/has at least one screw thread segment of at least one-fourth of a winding of a second screw thread type, which is compatible with said first screw thread type and which has a second thread side-form;
• and said second screw thread type is embodied in such a manner to reduce transition impedance from high-frequency electromagnetic disturbance signals between the two housing parts is lessened in comparison with said first screw thread type.
