Background
As shown in fig. 1, the movable contact of the frame circuit breaker is formed by welding a movable contact 40 and a movable contact 39. For a frame circuit breaker serving as a B-type power supply level protection switch, rated operating current is large during normal operation, and the indexes of switch temperature rise limitation and short-time breaking resistance are high, so that the brazing rate of a moving contact is required to be more than 85%, even more than 90%. And because the closing force of the frame switch is very large, the moving contact is subjected to very high impact force at the moment of closing, so that the heat affected zone of welding is required to be less than half of the height of the moving contact knife 40 to ensure that the moving contact has enough strength. Therefore, the movable contact knife 40 is pressed and conducted on two sides, and the structure scheme of the electric resistance welding clamp is ideal. When the length of the movable contact 39 is longer, especially when the length of the movable contact 39 used on a large-size frame switch and a PC-grade dual-power transfer switch is more than 10mm, the current is shunted on the contact surface of the lower electrode and the movable contact knife 40, so that the ideal welding fixture structure ensures that the contact of the electrode and the movable contact knife 40 is always completely parallel, but the common welding fixture in the market cannot ensure that the contact of the electrode and the movable contact knife 40 is always completely parallel, thereby influencing the brazing rate of the welded movable contact.
