Plum contact overview

Plum blossom contact is a kind of electric equipment accessories, because it is used in the primary circuit, so it is also called - secondary dynamic contact. Our company specializes in manufacturing plum contacts and other power equipment accessories, welcome to come to the drawing and sample customized. Plum blossom contacts are made of non-magnetic stainless steel and are used in center-mounted circuit breakers and other high-voltage and medium-voltage appliances, such as primary static contacts for ZN63 (VS1, VB1) and other center-mounted circuit breakers.

Plum blossom contact includes contact piece, support frame, tension spring, spring contact finger, support frame is ring-shaped, if thousands of contact pieces assembled on the support frame to form a ring-shaped body, in the ring-shaped body of the contact piece formed by the ring wall at both ends are provided with a contact and the second - touch, two tension springs were installed in the ring-shaped body of the ring-shaped body formed by the contact piece of the ring wall and with the first - touch and the second touch corresponds to the contact piece formed by the ring-shaped body of the ring. In the ring formed by the contact piece, a ring-shaped groove is provided on the outer side of the ring wall adjacent to the first contact, and a first spring finger is embedded in the ring-shaped groove; a second ring-shaped groove is provided on the inner side of the ring wall adjacent to the second contact in the ring formed by the contact piece, and a second spring finger is embedded in the second ring-shaped groove. After adopting this construction, the plum blossom contact in the conductive connection, on the basis of maintaining the original contact points, increases the contact points of the spring contact fingers, thereby increasing the conductive contact area and greatly improving its conductive connection performance.
