Abstract

In order to improve the shielding of a plug connector module ( 1, 1 ′) and of a plug connector modular system equipped therewith, in particular against high-frequency interference fields, the insulation body ( 10, 10 ′) of said module is form-fittingly surrounded all around by a shielding element ( 15, 15 ′). This additionally allows the earth connection of a metal plug connector modular frame ( 2 ) to a shield transfer element ( 14, 14 ′) of the plug connector module ( 1, 1 ′) and thus also an earth connection to a mating connector. Thus the shield element ( 15, 15 ′) itself is also earthed all around and at multiple points, and as a result can suppress the effect of in particular high-frequency electrical and/or magnetic interference fields particularly well.
