The beneficial effect of above-mentioned structure is: be provided with spacing boss on contact support, the movable contact spring is spacing through spacing boss, thereby can guarantee each movable contact spring assembly back, all in same position, guarantee the uniformity of assembly, the stroke of having guaranteed each movable contact spring is unanimous, be favorable to improving the breaking capacity of circuit breaker, and be provided with the groove of stepping down corresponding to each soft junction on the contact frame, the activity space of soft connection has been increased, when the circuit breaker bore heavy current, because the interact of electromagnetic force, the soft connection can be to the groove direction skew of stepping down, thereby the skew scope of soft connection is bigger, thereby be favorable to the electrodynamic force compensation, the short-term endurance has been improved to a certain extent. The intelligent universal circuit breaker contact support mechanism has the advantages of simple structure, stable and reliable performance, convenient assembly and capability of effectively improving the short-time tolerance of the circuit breaker.
Particularly, the two sides of the contact cover are respectively provided with a limiting insertion sheet, the contact support is respectively provided with a limiting groove corresponding to each limiting insertion sheet, and the limiting insertion sheets are clamped in the limiting grooves and form clamping fit of the contact cover and the contact support. The limiting insertion pieces on the two sides of the contact cover are clamped in the limiting grooves of the contact support, the two sides of the contact cover cannot deform due to heating, and the contact cover and the contact support are connected in a clamping fit mode, so that the contact cover and the contact support can be assembled conveniently.
Particularly, an arc-shaped groove is formed in the welding end of each moving contact, and one end of the flexible connection is welded in the arc-shaped groove. The flexible connection is welded in the arc-shaped groove of the moving contact, so that the flexible connection and the moving contact are connected more compactly, and the working reliability of the contact support mechanism is improved.
