[0002] The plum blossom contact is widely used in high-voltage vacuum circuit breakers, center cabinets, trolleys and other equipment. As an important primary conductive part, the plum blossom contact is made of a non-magnetic stainless steel ring tension spring tied to a contact finger ring. The contact finger ring is composed of a contact finger seat and multiple silver-plated copper contact pieces arranged along its ring. A contact finger groove for fixing the tension spring is provided on the contact piece. A clamp matching the clamping head on the contact arm of the equipment is provided on the inner side of the contact finger seat. The plum blossom contact is mounted on the contact arm through the clamping head. Its commonly used capacities are mainly 630A, 1250A, 1600A, 2000A, 3150A, and 4000A.
