Description

Electronic breaker dual-breakpoint mechanism
Technical field
The present invention relates to miniature circuit breaker field, specifically a kind of electronic breaker dual-breakpoint mechanism.
Background technology
In prior art, in electronic breaker, circuit breaker is realized by electronic component from the action of disjunction of threading off mostly, does not have actuating mechanism; Cause product can only be applied to small area analysis place, and overload capacity is poor.
Summary of the invention
The object of this invention is to provide a kind of actuating mechanism simple, energy quick-make disjunction, ampacity is large, electric arc is little, particularly more significant electronic breaker dual-breakpoint mechanism during short circuit surge, to overcome in prior art electronic breaker due to small area analysis place can only be applied to, and the shortcoming of overload capacity difference.
Technical scheme of the present invention is as follows:
A kind of electronic breaker dual-breakpoint mechanism, include housing, it is characterized in that: the both sides in described housing are installed with left and right fixed contact respectively, sliding sleeve is installed with between left and right fixed contact described in housing inherence, drive link is had to pass described sliding sleeve from top to bottom and be slidably matched with it, the lower end of described drive link is fixedly connected with connecting plate, the two ends of described connecting plate are installed with the left and right moving contact with described left and right fixed contact corresponding matching respectively, are connected with spring between the inner bottom surface of described connecting plate and described housing; The top of described housing is rotatablely equipped with handle, both sides bottom described handle are fixedly connected with cam and boss respectively, described cam is positioned at the top of described drive link, and the side of the inherent described boss of described housing is installed with coil, is fitted with iron core in described coil; Include flexure strip, the lower end of described flexure strip is fixed in described housing, and the upper end of flexure strip extends to the outside of described boss.
Described electronic breaker dual-breakpoint mechanism, is characterized in that: the rear end of described left and right fixed contact is connected to wire, and described wire is drawn respectively in described housing.
Described electronic breaker dual-breakpoint mechanism, is characterized in that: described flexure strip can pin described boss and handle when described handle rotates and drives boss to move upward.
Beneficial effect of the present invention:
It is simple that the present invention has actuating mechanism, energy quick-make disjunction, ampacity is large, electric arc is little, particularly more outstanding feature during short circuit surge, both overcome electronic breaker and be difficult to break-make big current and the negative effect and the insoluble unsteadiness of mechanical type circuit breaker that produce temperature effect, sensitivity is low, there is complex structure, the shortcoming of the problems such as assembling difficulty, current collection minor circuit breaker is highly sensitive again, reaction speed is fast, the advantage of good stability and mechanical type circuit breaker energy break-make big current is in one, and cost is low, volume is little, microminiaturized, stable performance, without temperature rise, easy to manufacture, the impact of ambient temperature can not be subject to and misoperation, also large electric arc can not be produced, extend the useful life of circuit breaker.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
See Fig. 1, a kind of electronic breaker dual-breakpoint mechanism, include housing 8, both sides in housing 8 are installed with left and right fixed contact 5,2 respectively, sliding sleeve 14 is installed with between the inherent left and right fixed contact 5,2 of housing 8, drive link 7 is had to pass sliding sleeve 14 from top to bottom and be slidably matched with it, the lower end of drive link 7 is fixedly connected with connecting plate 3, the two ends of connecting plate 3 are installed with the left and right moving contact 6,1 with left and right fixed contact 5,2 corresponding matching respectively, are connected with spring 4 between the inner bottom surface of connecting plate 3 and housing 8; The top of housing 8 is rotatablely equipped with handle 10, and the both sides bottom handle 10 are fixedly connected with cam 9 and boss 11 respectively, and cam 9 is positioned at the top of drive link 7, and the side of the inherent boss 11 of housing 8 is installed with coil 13, is fitted with iron core 15 in coil 13; Include flexure strip 12, the lower end of flexure strip 12 is fixed in housing 8, and the upper end of flexure strip 12 extends to the outside of boss 11.
In the present invention, the rear end of left and right fixed contact 5,2 is connected to wire, and wire is drawn respectively in housing 8, forms loop with power supply and load; Flexure strip 12 can pin boss 11 and handle 10 when handle 10 rotates and drives boss 11 to move upward.
Below in conjunction with accompanying drawing, the present invention is further illustrated:
When handle 10 rotates counterclockwise, band moving cam 9 makes arcuate movement downwards, cam 9 promotes drive link 7 and moves downward along sliding sleeve 14, and corresponding and left and right fixed contact 5,2 is closed respectively to drive left and right moving contact 6,1 by connecting plate 3, and Compress Spring 4 energy storage; Meanwhile, when handle 10 rotates counterclockwise, drive boss 11 to move upward, flexure strip 12 withstands boss 11, pins handle 10, makes above-mentioned dynamic/static contact be in closure state, whole circuit closed.
When obtaining trip signal, namely when coil 13 is energized, iron core 15 produces magnetic force and attracts flexure strip 12, flexure strip 12 is made to leave boss 11, spring 4 starts to reset and extends, and under the jacking effect of spring 4, connecting plate 3 drives drive link 7 actuating cam 9 to move upward reset, above-mentioned dynamic/static contact is separated, and whole loop disconnects.
