a charging socket fixed in the charging socket bracket and having an outer wall, an inner wall and a cavity located between the outer wall and the inner wall, the charging socket comprising at least one DC charging socket;
a charging socket cover, which is rotatably connected to the charging socket bracket via a rotary joint having a return spring and covers the DC charging socket in a first position and exposes the DC charging socket in a second position;
an undercut arranged on the rotary joint;
a retaining hook, wherein the retaining hook comprises:
(i) a socket pin, an underside of which is displaceable on the charging socket bracket and which has a tip which points in a direction of the DC charging socket, and
(ii) a joint pin, which is connected to an end region opposite the tip and leads away from the charging socket bracket at a predefined angle, wherein a free end of the joint pin has a retaining lug corresponding to the undercut;
a spring, which is arranged on the joint pin such that the joint pin is pressed in the direction of the charging socket;
a recess in the outer wall of the charging socket, which is arranged such that the tip of the socket pin is guidable through the recess, wherein
the undercut of the rotary joint and the retaining hook are arranged such that
