Connector for dynamic energy transfer system

A mobile machine, comprising:

• a frame;
• an arm connected to the frame;
• a contactor configured to receive electricity from a rail;
• and
• a rotational mount connecting the arm to the contactor, the rotational mount comprising:
• a joint comprising a first connector and a second connector, the first connector being connected to the arm, wherein the first connector is configured to rotate about a first axis, and the second connector is configured to rotate about a second axis;
• a joint bracket connected to the second connector of the joint, the joint bracket including a sleeve;
• and
• a contactor bracket connected to the contactor, the contactor bracket including a shaft, wherein the sleeve of the joint bracket surrounds the shaft of the contactor bracket, and the contactor bracket is configured to rotate about a third axis.

A mount assembly for connecting a rotating component to an arm, the mount assembly comprising:

• a joint comprising a first connector and a second connector, the first connector being configured to connect to the arm, wherein the first connector is configured to rotate about a first axis, the second connector is configured to rotate about a second axis, and the first axis is substantially perpendicular to the second axis;
• a joint bracket connected to the second connector of the joint, the joint bracket including a sleeve;
• a component bracket configured to connect to the rotating component, the component bracket including a shaft, wherein the sleeve of the joint bracket surrounds the shaft of the component bracket, the component bracket is configured to rotate about a third axis, and the third axis is substantially perpendicular to the first axis and the second axis;
• and
• first and second springs, wherein the first spring allows but opposes rotation in a clockwise direction about the third axis, and the second spring allows but opposes rotation in a counterclockwise direction about the third axis.
