Plug-in connector for transmitting data between coupled vehicles, and system and vehicle therewith

A plug-in connector device (64, 64a, 64b, 64c) for a vehicle (10), in particular a towing vehicle (12) or a vehicle trailer (14), for transmitting data, comprising:

• a first interface (66, 66a, 66b, 66c) for connection to a vehicle (10),
• a second interface (68, 68a, 68b, 68c) for connection to a connecting line (26, 74a, 74b, 74c, 137),
• wherein at least one of the first interface (66, 66a, 66b, 66c) and and/or the second interface (68, 68a, 68b, 68c) is a connecting element (28) for establishing a connection (22, 24) according to an ISO or SAE standard, in particular a connection (22) according to ISO 7638 or a connection (24) according to ISO 12098,
• a data interface (70, 70a, 70b, 70c) for connection to a data line (78, 84) of the vehicle (10),
• wherein the data interface (70, 70a, 70b, 70c) is electrically connected to the first interface (66, 66a, 66b, 66c) to transmit electrical signals (81) or data (79) between the data interface (70, 70a, 70b, 70c) and the second interface (68, 68a, 68b, 68c), and
• wherein the first interface (66, 66a, 66b, 66c) is electrically connected to the second interface (68, 68a, 68b, 68c) to transmit the electrical signals (81) or data (79) between the first interface (66, 66a, 66b, 66c) and the second interface (68, 68a, 68b, 68c).
