Roller contact with conductive brushes

A rolling contactor for providing electrical signal communication between a component terminal and a support structure for said rolling contactor, comprising:

• a) a plurality of electrically conductive circular rollers set in side-by-side arrangement, each said roller of finite thickness, each having formed thereon an outer rolling surface and an inner, centralized hole, between two, spaced-apart side walls, for rolling across the conductive terminal surface of a device under test (DUT), arranged in side-by-side position, to communicate one or more signals therewith;
• b) at least one electrically conductive circular spool for each roller, each said spool of smaller outside diameter than said roller, located adjacent and in contact with one of said roller side walls, having formed therethrough a centralized hole;
• c) a support axle for each roller adapted to pass axially through said holes formed in said roller and said spool and extending there beyond;
• d) an electrically conductive axle bracket adapted to support each said axle in a rotational arrangement thereabout to allow said roller surface to rotate and press against the termination surface of the DUT;
• e) an electrically conductive brush extending from each said support axle bracket to contact said spool in tangential arrangement during rotation thereof;
• and,
• f) an electrically conductive elongated spring arm extending between each said axle bracket and the support structure, to complete the electrical path between the termination surface of the DUT, said roller surface and said spool in contact with said axle bracket through said conductive brush, and to provide spring pressure to press said roller against said termination surface.
