Adapter for connecting a transmission line to a field device

An adapter for connecting a transmission line to a field device, wherein the device includes a housing having a housing wall with an opening, the adapter comprising;

• a shell insertable into said opening in said housing, wherein in an inserted state, the shell opens to an interior of the housing and closed to an exterior by an end wall of the shell;
• an insert including a base element with a window located in said base element and a projection, wherein the base element is arranged in said shell and said projection protrudes out of said shell through an opening in the end wall of said shell, wherein the base element has a basal area, wherein the basal area is greater than a basal area of the opening in the end wall of said shell;
• a connection element provided on an end of said projection and connected to the transmission line;
• a plurality of conductors extending through a bore in said projection and connected to a connection contact of said connection element, through said window of said base element, wherein said base element adjoins the bore in said projection and opening to the interior of the housing;
• and
• a potting compound filling a hollow space remaining in said shell;
• and
• a circuit board in said insert, wherein said circuit board is equipped with conductive traces, and each conductor is connected via one of said conductive traces with an associated connector, wherein with said conductive traces the conductor is connectable to an electronics of the field device.
