    摘要: A plug-in system for trailer vehicles provided with an automatic coupling system of the supply lines, including a plug (1) supporting the line contacts (1a) and a socket (2). The plug (1) has guide elements (4) that actively engage when approaching the guide elements (5) of the socket (2). The centering of a plug system for an automatic coupling system of supply lines on an articulated train is achieved by the guide elements (4) include a main guide pin (6) and at least one centering pin (7a, 7b) arranged at a distance therefrom. At least the centering pin (7a, 7b) and/or the associated guide element (5, 9) is elastic in the radial direction.
