Description
Technical field
The utility model relates to a kind of miniature circuit breaker, belong to breaker technical field.
Background technology
Miniature circuit breaker is as a kind of more ripe electrical equipment at present, is widely used for industry, business, high-rise and civilian
The various places such as house, be mainly used as office building, the illumination of house and similar building, distribution line and equipment overload and
Short-circuit protection, can act also as circuit, infrequently make-break operation is used with conversion；But the latching device in existing miniature circuit breaker
Relative complex, the sub-assembly of use is more, manipulation poor sensitivity easily occurs, easily breaks down, make so as to influence breaker
Use the life-span；The arc quenching effect of other arc-chutes also less stable, influence it is overall use sensitivity, influence using effect.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of the prior art, and provides one kind in prior art basis
Improved, simple and reasonable for structure, convenient using manipulation, performance is stable, and arc quenching effect is good, and high sensitivity, extension makes
With the miniature circuit breaker in life-span.
The purpose of this utility model is completed by following technical solution, a kind of miniature circuit breaker, including housing, behaviour
Make mechanism, contact mechanism, electromagnetic release mechanism and arc-chutes, described operating mechanism includes a handle for being exposed at housing,
The handle the inner is connected by a U type connecting rod with a lever, and described lever is distinguished by central shaft and countershaft in a manner of anchor ear
Splicing has the lock that can mutually rotate and contact support plate, and mutually forms three-in-one latch device, on the contact support plate
Moving contact be engaged with the static contact on the outside of the arc-chutes；The unlocking of heated bending top is installed with the snap fit
Detain to realize the bimetal leaf of the de- mouth of heat.
As preferred：Reaction spring is provided with the side of described central shaft, is provided with opposite side and acts on lock
Latch spring；The touch spring for acting on contact support plate is provided with described countershaft；Described electromagnetic release mechanism by
Axial arranged removable dynamic iron core and be nested with outside iron core, overcurrent produces magnetic field and the coil composition with dynamic iron core movement,
Multiple tracks is provided with striking passage between electromagnetic release mechanism and arc-chutes and plays the flow deflector for leading arc effect, described housing
Binding post is separately installed with inside both sides.
The utility model is that one kind of prior art is improved, it have it is simple and reasonable for structure, it is convenient using manipulation, make
With stable performance, arc quenching effect is good, high sensitivity, the features such as increasing the service life.
Brief description of the drawings

Mutually composition three-in-one latch device, the moving contact 13 on the contact support plate 12 and the stationary contact installed in the outside of arc-chutes 5
First 14 are engaged；Heated bending top opening lock catch is ordinatedly installed to realize the bimetal leaf 15 of thermal tripping with the lock 11.
Shown in figure, reaction spring 16 is provided with the side of described central shaft 9, is provided with opposite side and acts on lock
The latch spring 17 of button 11；The touch spring 18 for acting on contact support plate 12 is provided with described countershaft 10；Described electricity
Magnetic tripping mechanism 4 by axial arranged removable dynamic iron core 19 and be nested with outside iron core, overcurrent produces magnetic field and with dynamic iron core
Mobile coil 20 forms, be provided with the striking passage between electromagnetic release mechanism 4 and arc-chutes 5 multiple tracks play lead arc effect
Flow deflector 21, be separately installed with binding post 22 inside the described both sides of housing 1.
