Background technology
Miniature circuit breaker is protected circuit and is generally divided into short-circuit protection and overload protection two class, and the electromagnetic tripping system of circuit breaker internal is exactly to the design that it is protected when short trouble appears in circuit.
Electromagnetic tripping system includes yoke, coil, coil rack, terminal block, dynamic iron core, static iron core, push rod and iron core spring etc., and wherein, coil, dynamic iron core, static iron core are electromagnetic component.
Circuit breaker in the market, electromagnetic component and push rod, iron core spring are assemblied on coil rack and form electromagnetic assembly, then electromagnetic assembly and yoke, terminal block and/or fixed contact are welded together, this electromagnetic assembly complex structure, pad is many and welding difficulty is large, and efficiency of assembling is very low.
Utility model content
To this, it is more reasonable that the utility model aims to provide a kind of structure, is beneficial to the circuit breaker electromagnetic tripping system of assembling.
The technical scheme realizing the utility model object is:
A kind of circuit breaker electromagnetic tripping system, comprise terminal block, coil, fixed contact, coil rack, dynamic iron core, static iron core, iron core spring, push rod and yoke, described terminal block, coil and fixed contact are weldingly connected formation coil block successively, described static iron core, dynamic iron core, iron core spring and push rod load the central through hole interior formation core assembly of described coil rack, described core assembly is inserted in described coil, in shell block, the position corresponding with described core assembly two ends forms mounting bracket, described each mounting bracket is provided with the first stopper slot, described yoke two ends form the second stopper slot forming the spacing hole being suitable for spacing described core assembly with described first stopper slot split, the shallow slot matched with described yoke is formed in described shell block, cap inwall forms the yoke limit rib compressing spacing described yoke, on described shell block and described cap, the position corresponding with described terminal block forms terminal block location notch.
In technique scheme, the shape of described yoke is n shape, and the shape of described shallow slot is the n shape matched with it.
In technique scheme, described shell block forms and to offset with described fixed contact thus to realize locating the boss of described fixed contact.
The utility model has positive effect: (1) is compared with existing circuit breaker electric magnetic tripping system, the simple electromagnetic tripping system of electromagnetic structure in the utility model only has two solder joints, three weldments (terminal block, coil and fixed contact), structure is simple, welding difficulty is little, welding quality is high, changes the technique of electromagnetic tripping system, and be welded as main, be assembled into auxiliary, structure, reduce assembly difficulty dexterously, effectively improve efficiency of assembling.
