High voltage multipliers and filament transformers for portable X-ray inspection units

A multi-stage DC voltage multiplier assembly having a plurality of serially-connected voltage multiplying-rectifying stages, including:

• a series-connected array of capacitors each having an insulating outer shell and having two internally threaded ferrule terminals projecting coaxially beyond said outer shell, a ferrule terminal of each capacitor being aligned in co-axial juxtaposition with a ferrule terminal of the next adjacent capacitor, forming a co-axially aligned array of pairs of capacitors,
• a length of threaded rod threaded into the coaxially aligned ferrules of each adjacent pair of capacitors,
• and a conductive electrical connector having a first bore loosely fitting without binding on said threaded rod and at least two prongs defining between themselves a slot extending substantially radially from the axis of said threaded rod and ferrules, said slot being dimensioned to accommodate an electrical conductor inserted radially therein, with a clamping screw engaged in a second bore extending transverse to said slot through said prongs, said second bore extending through a first prong and into a last prong and with the clamping screw spanning each said slot at a point intermediate its radial length, and extending into threaded engagement with a reduced diameter threaded end of said second bore in the last prong,
• whereby tightening of the clamping screw in the second bore deforms the prongs to clamp each said electrical conductor inserted in said radial slot.
