Abstract

Connector (100) for a high-voltage plug connection (10) for the electrical connection of high-voltage components, in particular an electric drive system of a motor vehicle, which has at least one electrical contact arrangement, where the contact arrangement - at least one contact element (102); - a first inner protective element (104) which is arranged inside the contact element and projects beyond the contact element (102); and - a first outer protective element (108) which at least partially surrounds the contact element (102) and protrudes from the contact element (102), wherein the first inner protective element (104) and the first outer protective element (108) form a touch protection for the contact element (102), characterized in that the contact element (102) has an annular contact surface which is inclined and / or bent with respect to a longitudinal axis (L) of the high-voltage connector (10).
