two fastening-side joints attached to the connector housing; and
two joint elements, each joint element connecting one of the flap-side joints to one of the fastening-side joints; and
a spring element locking the cover flap in each of an open position and a closed position of the cover flap relative to the connector housing.
9 . The connector assembly according to claim 8 , wherein the connector housing is a housing of a charging connector of an electric vehicle.
10 . The connector assembly according to claim 8 , wherein an axis of rotation of the cover flap relative to the connector housing defined by the four-joint hinge lies outside of the cover flap.
11 . The connector assembly according to claim 8 , wherein at least one sealing element is arranged between the cover flap and the connector housing in a closed position of the cover flap.
12 . The connector assembly according to claim 11 , wherein the connector housing includes a socket adapted to receive a mating connector, the socket accessible from the outside in an open position of the cover flap.
13 . The connector assembly according to claim 12 , further comprising a protrusion projecting beyond at least one of a plug face or the socket of the connector housing and to which at least one of the two fastening-side joints is attached.
14 . The connector assembly according to claim 13 , further comprising a drive device adapted to bias the cover flap into at least one of the open or closed positions.
15 . The connector assembly according to claim 14 , further comprising a cantilever to which the drive device is attached.
16 . The connector assembly according to claim 15 , wherein the cantilever is monolithically formed with the connector housing.
17 . The connector assembly according to claim 15 , wherein the cantilever extends along a cantilever direction between a plane of a plug face of the connector housing and a mating direction of the connector housing.
18 . A plug cover hinge of a charging connection of an electric vehicle, comprising:
a cover flap;
a four-joint hinge defining two flap-side joints attached to the cover flap and two fastening-side joints attachable to a frame, the four-joint hinge including two joint elements, each joint element connecting one of the flap-side joints to one of the fastening-side joints;
a drive device moving the cover flap; and
a gear coupling the cover flap to the drive device in a force-transmitting manner.
19 . A connector assembly, comprising:
a connector housing;
a plug cover hinge attached to the connector housing, including
a cover flap; and
a four-joint hinge, including:
two flap-side joints attached to the cover flap;
two fastening-side joints attached to the connector housing; and
two joint elements, each joint element connecting one of the flap-side joints to one of the fastening-side joints; and
