TERMINAL ASSEMBLY FOR CONDUCTOR ROD HAVING MULTIPLE DEGREES OF FREEDOM

A work machine, such as a hauler at a mining site, includes a conductor rod housing concentric metal tubes for receiving multiple poles of electrical power from a contactor sliding on a power rail. A terminal assembly includes conductive extensions from the respective metal tubes that are arranged concentrically and rotatably around an axis orthogonal with the conductor rod, rotatable metal pins positioned transversely to the axis, and conductive arms connected through hinge joints to respective ones of the rotatable metal pins. When the conductive arms are connected to rotatable and hinged joints at the contactor, the terminal assembly provides multiple degrees of freedom for the conductor rod relative to the contactor and avoids detachment of the contactor from the power rail.
