The invention provides a
circuit breaker overhauling contact. The contact comprises a contact body inserted into a moving contact, and the contact body comprises a bottom plate, clamping pieces and an adjusting rod; a through hole is formed in the bottom plate, and the clamping pieces are arranged on the bottom plate in the circumferential direction of the bottom plate; the bottom plate and the clamping pieces form a variable-
diameter sleeve, and the clamping pieces are provided with
test line connecting positions; the adjusting rod is arranged in the variable-
diameter sleeve, one end of the adjusting rod penetrates through the through hole, and the adjusting rod can move back and forth along the through hole; an annular
flange is arranged on the portion, in the variable-
diameter sleeve, of the adjusting rod and used for supporting the clamping pieces, and the clamping pieces can be in contact with the moving contact. According to the
circuit breaker overhauling contact, the adjusting rod moves back and forth in the variable-diameter sleeve, so that the annular
flange supports the clamping pieces, and the contact between the clamping pieces and the movable contact is achieved; a
test line during overhauling is prevented from being directly connected with a contact finger spring, damage to the contact finger spring is avoided, and the situation that contact between the moving contact and a static contact is poor in operation is avoided. The field operation efficiency is improved, the working quality is improved, and the
standardization and normalization of the operation process are ensured.
