A BUSHING FOR A HIGH-VOLTAGE DC RELAY

摘要

Title: A BUSHING FOR A HIGH-VOLTAGE DC RELAY Abstract The present invention relates to a bushing for a high-voltage DC relay. The bushing for a high-voltage DC relay is provided, wherein a through guide hole is formed on the bushing; an inner wall of the guide hole is a smooth structure, and a number of ribs protruding outward are formed on an outer wall of the bushing; and the ribs are arranged longitudinally and are parallel to an axis of the bushing. By providing ribs having a certain thickness on the outer wall of the bushing, the bushing is pressed into a via hole of the yoke plate and the bushing is clamped in the via hole due to the deformation of the ribs, without causing any damage to the via hole of the yoke plate. ------ --- --- ----- -- I l a -- - - - -- -- - - - ---- ----------
