Contact device, - having a contact housing, a base, a tensioning device and a latching device, - the base delimiting a base interior space, - the contact housing engaging at least in sections into the base interior space, - the latching device having a latching structure and at least one latching pin on an outer housing circumferential side of the contact housing, - the latching structure having a spur toothing system and an unlatching section which adjoins the spur toothing system in the axial direction, - the unlatching section being of groove-shaped configuration in the circumferential direction at least in sections so as to run around the contact housing, - the latching pin being connected to the base and protruding into the base interior space, - the tensioning device being arranged between the base and the contact housing in the base interior space, - it being possible for the contact housing to be displaced relative to the base in the axial direction counter to the action of the tensioning device between a first axial position and a second axial position, - the latching pin engaging into the spur toothing system in the first axial position, and securing a position of the contact housing with respect to the base in the circumferential direction, - the latching pin engaging into the unlatching section in the second axial position, and it being possible for the contact housing to be rotated in the circumferential direction about a rotational axis with respect to the base, - the tensioning device providing, in the second axial position, an axial force (F A3) for the transfer of the contact housing back into the first axial position. - having a contact housing, a base, a tensioning device and a latching device, - the base delimiting a base interior space, - the contact housing engaging at least in sections into the base interior space, - the latching device having a latching structure and at least one latching pin on an outer housing circumferential side of the contact housing, - the latching structure having a spur toothing system and an unlatching section which adjoins the spur toothing system in the axial direction, - the unlatching section being of groove-shaped configuration in the circumferential direction at least in sections so as to run around the contact housing, - the latching pin being connected to the base and protruding into the base interior space, - the tensioning device being arranged between the base and the contact housing in the base interior space, - it being possible for the contact housing to be displaced relative to the base in the axial direction counter to the action of the tensioning device between a first axial position and a second axial position, - the latching pin engaging into the spur toothing system in the first axial position, and securing a position of the contact housing with respect to the base in the circumferential direction, - the latching pin engaging into the unlatching section in the second axial position, and it being possible for the contact housing to be rotated in the circumferential direction about a rotational axis with respect to the base, - the tensioning device providing, in the second axial position, an axial force (F A3) for the transfer of the contact housing back into the first axial position.
