Abstract
Disclosed is a high-frequency-tuning sliding electrical contact. The contact includes a tuning ring which is composed of an inner elastic piece, an upper base, an outer elastic piece and a lower base. Pull rods are welded to an upper side face of the upper base, and upper ends of the pull rods are driven to move up and down by a motor, so that the tuning ring slides up and down between the outer sleeve and the inner sleeve along the pull rods. The overall structure of the novel electrical contact is simple, compact and economical. The disclosure reduces joule heat produced by contact resistance and prevents contact surface fusion welding or conductive damage, and is especially suitable for tuning in a small gap range.
