Abstract
A housing for a field device of automation technology with a screwed connection, which connects a first housing part with an external thread with a second housing part with an internal thread. The screwed connection provides a transition impedance lessened for EMC disturbance signals. The reduction of the transition impedance is achieved by including in the screw thread a screw thread segment, in which a second screw thread type is designed in contrast to a first screw thread type located outside of the screw thread segment to provide a lessened transition impedance. Besides the basic provision that the screw thread is electrically conductive at least in corresponding portions, the second screw thread type can be differently embodied, in order to achieve the lessened transition impedance. This can occur, on the one hand, by providing the second screw thread type as round threads. However, other forms of embodiment of the screw thread segment are possible.
