1. An electrical plug connector, having a housing (1), which has a central insertion opening (2) and an outer annular insertion opening (3), wherein the outer insertion opening (3) surrounds the central insertion opening (2) coaxially and is delimited from the central insertion opening (2) by an equally coaxial cylindrical partition wall (4), which extends at least over a part of the circumference of the central insertion opening (2), with at least one guide (31) for a complementary plug connector (5, 10) with at least one electrical contact pin (8, 9, 101), wherein the guides (31) ensure the rotation-free insertion of the complementary plug connector (5) into the outer annular insertion opening (3) and enable a subsequent rotation about the central axis of the plug connector and the complementary plug connector (1, 5), wherein at least one flat electrical contact element (13, 14) with a tongue-shaped design that is elastically deflectable out of a path of the contact pin (8, 9, 101) in the central insertion opening or the outer annular insertion opening (2, 3) is mounted in the housing (1) and protrudes into the central insertion opening or the outer annular insertion opening when the complementary plug connector is absent, wherein, when the complementary plug connector (5) is fully inserted, a flat contact section (134, 144) of the contact element (13, 14), adjoining a lateral edge (132, 142) of the flat contact section in the transverse direction, abuts in contact with the contact pin (8, 9), and wherein the flat electrical contact element (14) is arranged in a region of an outer side of the cylindrical partition wall (4) so as to extend in parallel with the axis of the insertion openings (2, 3) and is resiliently deflectable in the direction towards the central longitudinal axis of the housing (1), wherein the flat electrical contact element (14) has a convex curvature in the direction away from the central longitudinal axis of the housing (1), and the lateral edge (142) of this flat electrical contact element (14) facing the contact pin (8, 9), in its front section (143) facing the contact pin, encloses an acute angle with the path of the contact pin (8, 9) during the insertion when viewed in a direction of the lateral edge to show the deflection of the flat electrical contact element (14), wherein the front section (143) of the flat electrical contact element (14) cooperating with the contact pin (8) is rotated in the direction towards the contact pin (8), and a rotation steadily increases from a contact region (145) up to shortly before the front end (148) of the flat electrical contact element (14).
