Circuit breaker electrical contact support member and preparation method thereof

The invention discloses a circuit breaker electrical contact support member and a preparation method thereof. The support member comprises a support member body made of a Cu/Fe/Cu material strip. One side of the support member body is provided with a built-in groove; the groove is embedded by a conductive insert block; and the insert block is provided with a contact point. The method is characterized by, carrying out thermal treatment on the Cu/Fe/Cu material strip, and rolling the Cu/Fe/Cu material strip obtained after thermal treatment; carrying out punching on the Cu/Fe/Cu material strip obtained after rolling to prepare the support member body; preparing the insert block, and inserting and welding the insert block to one side of the obtained support member body; and welding the contact point to the other side of the insert block. The support member is prepared by inserting the Cu block or other conductive metal blocks into the Cu/Fe/Cu composite strip, thereby improving the strength of the contact support member, ensuring stability of the current conduction when an electrical contact is contacted, and meanwhile, reducing copper material consumption and saving cost.
