Not in a particular one Orientation of coaxial connector elements built into a connector housing can therefore not differently than before more the cause of a poor electrical connection between the coaxial connector element and the pin header be. A special kind of orientation or orientation of the coaxial connector element and of this receiving connector housing in Assembly of the same can therefore be omitted. Corresponding applies to the alignment of the inner conductor contact element relative to the outer conductor contact element.
