Abstract

A frame assembly for affording mechanical support and for carrying electrical conduction paths for connection to circuitry of a machine. The frame assembly includes members comprising pultrusions having an insulating body and reinforcing fibers within the insulating body, and has grooves in surface portions along an elongated dimension with conductors in the grooves. The conductors provide electrical conduction paths that are connectable to circuitry of the machine. The pultrusion may be a thermal setting polymer, for example, selected from the group consisting essentially of polyester, vinyl ester, and epoxies, and may be reinforced with fiberglass. The frame member can also have a hollow interior portion within which conductors are arranged to conduct AC power to the circuitry of the machine, and the conductors on the exterior surface of the frame member can be arranged to conduct IIOC bus signals. When a plurality of the frame members are connected together to form a frame assembly, corresponding conductors of each are interconnected to facilitate supplying and directing the electrical signals to the machine. The connections can be made to and among the electrical conductors carried by the pultrusions by blocks that are attachable to the pultrusions.
