Plum blossom contact is a kind of electrical equipment accessories, because it is used in the primary circuit, it is also called-secondary moving contact. The company specializes in manufacturing plum blossom contacts and other power equipment accessories. Welcome to make customized drawings and samples. The plum blossom contact body is made of non-magnetic stainless steel and is used in mid-mounted circuit breakers and other high-voltage medium-voltage devices. For example, the primary static contact can be used in mid-mounted circuit breakers such as ZN63 (VS1, VB1).
The plum blossom contact includes a contact piece, a support frame, a tension spring, and a spring contact finger. The support frame is ring-shaped. The contact pieces of Ruoqian are assembled on the support frame to form a ring body. The two ends of the ring body formed by the contact pieces are respectively provided with a ring. Head and second-head, two tension springs are respectively installed on the outer ring wall formed by the contact piece and correspond to the first-head and second head, and are next to the first-hand head on the ring-shaped inner ring wall formed by the contact piece. An annular groove is provided on the outer side, and a first spring contact finger is embedded in the annular groove; a second annular groove is provided on the inner ring wall of the annular body formed by the contact piece next to the second contact, and the second annular groove A second spring contact finger is embedded in the groove. After adopting this structure, in the conductive connection of the plum contact, on the basis of maintaining the original contact point, the contact point of the spring contact finger is increased, thereby increasing the conductive contact area and greatly improving the conductive connection performance.
