Abstract: An RF coaxial plug connector part includes coaxial plug parts disposed at a front of a housing of a coaxial plug part module mounted on or attached to a board, for example a printed circuit board. The housing has a grid-type frame which defines its external dimensions, is open on all sides, has frame parts that are disposed at right angles to one another, and is made of a first plastic, which cannot be metallized. Free spaces in the grid-type frame are completely filled with cable inserts which are DC-isolated from one another by the frame parts and are made of a second plastic, which can be metallized. At least one coaxial connecting cable, which extends from the front surface to the lower surface of the housing is integrated in each of the cable inserts.
