The invention relates to an electromagnetic system of a small circuit breaker. The invention mainly solves the problems of inconvenient welding operation and poor positioning stability of the coil and the yoke existing in the existing small circuit breaker electromagnetic system. It includes a yoke, a coil bobbin and a coil. The yoke includes a support plate. One end of the coil bobbin is provided with a first lug and a second lug in the vertical direction. The first lug is provided with a "U"-shaped first through slot. , the side of the first lug is provided with a first flange, the second lug is provided with a second slot of "L", the second slot includes a vertical slot and a horizontal slot, the second tab The side of the side is located below the horizontal part and is provided with a second convex edge. The first through slot and the vertical part are distributed in the vertical direction correspondingly and the openings are facing oppositely. The support plates are respectively fitted into the first through slot and the second through The side of the support plate is provided with a first notch and a second notch, the first notch engages with the first convex edge, and the second notch engages with the second convex edge. Because the new electromagnetic system adopts a unique installation structure, the positioning effect of the coil skeleton and the yoke is good, the stability is high, the coil welding is convenient, and it is easy to operate.
Description
technical field [0001] The invention relates to a circuit breaker, in particular to an electromagnetic system of a small circuit breaker and the small circuit breaker. Background technique [0002] Miniature circuit breakers have a wide range of applications and are mainly used in various places such as industry, commerce, high-rise buildings and residential buildings. At present, the electromagnetic system of small circuit breakers on the market mainly includes a yoke, a static contact, a coil bobbin, a coil, a moving iron core, a static iron core, and a ejector rod. The installation of the coil bobbin on the yoke is prone to poor positioning effect, making When the coil is welded and installed, the coil skeleton is prone to swing, which causes inconvenience to the coil welding. In addition, the static contact and the yoke adopt a welded structure, and the welding resistance is large, which is not conducive to the cooling of the product, and cannot effectively ensure the a...
