Description
Technical field
The present invention relates to a kind of miniature circuit breaker, especially a kind of plug-in type energy storage high-breaking miniature breaker.
Background technology
Miniature circuit breaker is a kind of conventional electric switch, is mainly used in the various places such as industry, business, residential houses.Miniature circuit breaker mainly by operating mechanism come control circuit deciliter, operating mechanism is mainly comprised of snap close, tripping, support, " U " type connecting rod and handle, is provided with an extension spring between support and housing, moving contact is fixed on support; Tripping is clamped in the upper right corner of support and is hinged with support, and snap close is hinged on the left side central portion of support and block mutually with tripping the upper end of snap close, between tripping and handle, by " U " type connecting rod, is connected.Handle is when closure state, between moving contact and fixed contact, form certain pressure, need to reach good electrical connection properties, because moving contact is fixed on support, between moving contact and support for being rigidly connected, compensation very close to each other between moving contact and fixed contact, therefore, the installation accuracy of moving contact and fixed contact is had relatively high expectations, so just can avoid moving contact and fixed contact when closure, to produce minim gap, position accuracy demand is higher, and assembly difficulty is large.The operating mechanism of existing miniature circuit breaker also has moving contact is hinged on support, by torsion spring being set between support and moving contact, provide backlash compensation, but this structure can cause the assembling of product loaded down with trivial details, easily breaks down, stability is bad, has increased the cost of product.
Summary of the invention
For above-mentioned reasons, the object of the present invention is to provide a kind of simple in structure, easily assembling, the plug-in type energy storage high-breaking miniature breaker of stable performance.
For achieving the above object, the present invention adopts a kind of plug-in type energy storage high-breaking miniature breaker, comprises the operating mechanism in housing and holder housing, electromagnetic system, bimetal leaf, arc control device, binding post, operating mechanism comprises movable contact block, moving contact, snap close, tripping, U-shaped bar, handle, extension spring, two golden pull bars, moving contact is fixedly installed on movable contact block, tripping one end is hinged on movable contact block upper end, the other end forms U-shaped lever attachment hole, movable contact block middle part forms a horizontal waist through hole, in waist through hole, placed contact axle, snap close is hinged on contact axle, snap close extends to form locking bar towards tripping, locking bar top forms step-shaped top in U-shaped lever attachment hole one end of tripping, two golden pull bars one end is hinged on snap close, the other end is overlapped on bimetal leaf upper end, movable contact block inner side is provided with snap close torsion spring, snap close torsion spring one end is fixed on movable contact block, the other end is connected on snap close, extension spring one end is connected on housing, the other end is connected on the movable contact block of top of waist through hole, U-shaped bar two ends be connected on handle and the U-shaped lever attachment hole of tripping in.
Main effect of the present invention is that movable contact block is horizontally arranged with waist through hole, in the process that product is closed or disconnection is moved, contact axle can be movable in waist through hole, when switch is closed, by the comprehensive function of U-shaped bar and extension spring, movable contact block is moved to fixed contact, and for moving contact provides backlash compensation, and moving contact only need to be fixed on movable contact block, saved the step that torsion spring is set between moving contact and contact base, made the structure of operating mechanism simpler.
The present invention is further set to described plug-in type energy storage high-breaking miniature breaker and also comprises stored energy mechanism, stored energy mechanism comprises energy storage lever and countercheck rod, energy storage lever center hinge is connected on housing, one end and handle are connected, the other end and countercheck rod are hinged, and countercheck rod is arranged on movable contact block the place ahead.Described countercheck rod below forms the stopper of a small volume, and movable contact block correspondence forms a salient point forwardly at stopper.
Stored energy mechanism plays the object of quick-make: start turning handle, U-shaped bar promotes tripping, make snap close and tripping meshing, thereby promoting tripping, snap close, movable contact block and movable contact head sways, when handle motion is to certain angle, on movable contact block, salient point withstands on countercheck rod, movable contact block and moving contact stop travelling forward, continue motion handle motion to certain angle, handle promotes energy storage lever, energy storage lever pulls countercheck rod to move upward, and countercheck rod is separated with movable contact block, moving contact quick-make under the effect of extension spring power.
The present invention is further set to be provided with a plurality of steam vents on the housing at described arc control device rear.
Above-mentioned steam vent body is specifically set to three, is separately positioned on binding post place, binding post below and the housing bottom of housing.
On housing between the steam vent of above-mentioned housing bottom and arc control device rear, form an exhaust passage.
Traditional product only arranges place's exhaust outlet, when the present invention compares disjunction with traditional product, is more conducive to the discharge of gas, has improved the breaking capacity of product.
The housing both sides that the present invention is further set to described arc control device front end are provided with flash barrier, flash barrier inner side forms inclined-plane, between flash barrier, by inclined-plane, form the arc passage narrowing down gradually, the top of two flash barriers forms the push rod mutually supporting relatively, is provided with the run-on tab being connected with bimetal leaf between the below of two flash barriers.Flash barrier top is supported mutually by push rod, and the run-on tab of below between passing through supports, and makes the setting of flash barrier more stable, can mutually not draw close.
The present invention is further set to described movable contact block lower end and forms the moving contact groove suitable with moving contact, and moving contact is fixedly installed in moving contact groove.Moving contact is placed in the moving contact groove of movable contact block, compares saved the operations such as the fixing and screw of gluing is fixing with tradition, provides cost savings.
