This invention relates to a mechanism for connecting and disconnecting service lines between a pair of relatively articulated vehicles, such as electrical service lines and service lines for pressurized operating fluids, between a tractor and a semitrailer, one of which having a fifth wheel and the other a king pin and each having one connector in the vicinity of the fifth wheel and the king pin, respectively, for the connection of said service lines, one of said connectors being mounted on a support which is reciprocably movable along a circular path having its center on the common geometrical axis of the fifth wheel and king pin when coupled together, whereby said one connector is free to be moved on one vehicle by the other connector which is fixed to the other vehicle in case of articulation between the tractor and the semitrailer, and one of said connectors being movable in relation to the other into and out of engagement therewith by means of an operating mechanism for the connecting and disconnecting of the service lines.
A mechanism for connecting and disconnecting service lines, such as electrical service lines and service lines for pressurized operating fluids, between a tractor and a semi-trailer having a fifth wheel and king pin, respectively, comprising at least one connector associated with the service lines of the semi-trailer at a distance from the king pin center and at least one connector associated with the service lines of the tractor at the same distance from the fifth wheel center for the king pin, each of said connectors mounted on the respective vehicle units with one of said connectors mounted for movement about the respective center whereby the connector is reciprocably movable along a circular path about the common geometrical axis of the aligned king pin and fifth wheel centers, operating means on one of said vehicle units for moving a respective one of said connectors relative to the other to connect said connectors together whereby after mechanical coupling of the vehicle units said units may articulate with retained engagement between the two connectors.
