Abstract: An HF plug connection system with low transfer resistance even in the high frequencies in the range of 10.sup.8 Hz, comprising a standardised socket insert and a corresponding plug as plug connector parts. In this system, an earthed screening (10) runs from cable to cable (16) through both parts of the plug connector. It is connected over a large area to the metal braid (36) of the HF cable (16) of one and/or the other plug connector part, with large surface area throughout in relation to the cross-section, and at least one flexible area (26, 28) outside the insulation sheath (34), and the screening is passed to large contact areas (46) for the complementary part of the plug connector. Thus the cable end can be adjusted to any required angle, which allows a shorter installation length.
