20090008903 | Plug-In Connections - Disclosed is a plug-in coupling system for joining cables between a tractor and a trailer. The invention also relates to the individual components, i.e. the semitrailer coupling and the plug-in connector on which the invention is implemented. The cables between the tractor and the trailer are usually plugged into each other by hand. Automatic systems have not been successful on the market so far. The aim of the invention is therefore to create a plug-in coupling system which allows the supply cables to be connected in a comfortable and operationally safe manner when the trailer is joined to and disconnected from the tractor. Said aim is achieved, among other things, by disposing the socket in a stationary manner below the insertion hole on the semitrailer coupling while arranging the contact points of the plug below the king pin on the plug-in connector. | 01-08-2009 |
