A downhole tool string component having a tubular body having a bore with a central longitudinal axis. An electrical conductor assembly is disposed within the bore of the tubular component, the assembly having signal couplers at first and second ends adapted for a butt connection. Centering assemblies are disposed within each end of the bore and have a plurality of projections extending radially outward from at least a partial central ring disposed around a portion of each end of the electrical conductor assembly, at least one centering assembly comprising a radial opening in the central ring adapted to receive the electrical conductor assembly. The first and second ends of the electrical conductor assembly are substantially aligned to the central axis of the bore at each end by the centering assemblies, the centering assemblies being adapted to allow fluid to pass through the bore.
