Specific embodiments
Below in conjunction with accompanying drawing embodiment of the present utility model is made a detailed explanation.
A kind of snap close electromagnetism coupling circuit breaker as shown in Figure 1, this circuit breaker comprise base 1, support 8, moving contact 2, fixed contact 4, moving crane span structure 12, latching device 3, making electromagnet 5, connecting rod 11 and separating brake release 9.Support 8 is fixedly installed on the base 1, the setting that cooperatively interacts of moving contact 2 and fixed contact 4.As shown in Figure 2, moving crane span structure 12 is made of base plate 121, cover plate 123, and moving contact 2 is sandwiched between base plate 121 and the cover plate 123, also is placed with the 3rd spring 122 between moving contact 2 and the cover plate 121.As Fig. 5, shown in Figure 6, the middle part of moving crane span structure 12 is hinged by rotating shaft 10 and support 8, be provided with first spring 7 of keeping moving contact 2 one end perks between other end end and the support 8, and on a side of moving crane span structure 12, be provided with lateral pin 13, the bottom of moving crane span structure 12 is provided with armature 6, and described making electromagnet 5 is arranged on the base 1 of moving crane span structure 12 belows the use that matches with armature 6.
As Fig. 1, shown in Figure 3, described latching device 3 is installed on the base 1, latching device 3 is made of framework 31, interior cover 32, second spring 33 and dead bolt 34, interior cover 32 is arranged in the framework 31, overlap in 32 in second spring 33 and dead bolt 34 are successively set on, and be provided with poke hole 37 on dead bolt 34 tops, and being provided with inclined-plane 35 above the head of dead bolt 34, inclined-plane 35 cooperates with described lateral pin 13 quadratures; Described connecting rod 11 hinged being arranged on the described framework 31, connecting rod 11 is provided with one and stirs nose 14 below pin joint, describedly stir that nose 14 inserts frameworks 31 and interior cover 2 matches with poke hole 37, is used to stir dead bolt 34.As Fig. 4, shown in Figure 5, described separating brake release 9 is mounted on the support 8, and separating brake release 9 has solenoid 91 and magnetic core 92 to constitute, and magnetic core 92 is arranged in the solenoid 91, the top of magnetic core 92 is provided with toroidal frame 93, being inserted in the toroidal frame 93 of described connecting rod 11.
As shown in Figure 4, when circuit breaker was in gate-dividing state, moving crane span structure 12 was upwards dug by the tension force effect of first spring 7, and moving contact 2 separates with fixed contact 4.Cover 32 outsides in the dead bolt 34 of latching device 3 stretches out.After giving the coil electricity of making electromagnet 5, produce the moving crane span structure 12 of suction drive between the armature 6 on making electromagnet 5 and the moving crane span structure 12 and move downward.When the lateral pin 13 on the moving crane span structure 12 contacted with the dead bolt 34 of latching device 3, because dead bolt 34 has inclined-plane 35, lateral pin 13 slides on the inclined-plane had inside thrust to dead bolt 34, and second spring 33 in oppressing in the cover 32 makes in dead bolt 34 retractions and overlaps in 32.When lateral pin 13 is crossed dead bolt 34 positions and since dead bolt 34 suffered inside thrusts disappear in stretch out again under the effect of second spring, 33 tension force in cover 32 outsides, this moment, moving contact 2 contacted the combined floodgate (as shown in Figure 5) of having realized circuit breaker with fixed contact 4.Disconnect the power supply of the coil of making electromagnet 5 this moment, the suction between making electromagnet 5 and the armature 6 disappears, and the tension force of spring 7 makes crane span structure 12 that the upwards active force of motion be arranged, lateral pin 13 compressing dead bolts 34.But because dead bolt 34 bottoms are that a plane does not have the inclined-plane, dead bolt 34 can't overlap in 32 in the retraction, and lateral pin 13 can't be crossed dead bolt 13, and moving crane span structure 12 is kept motionless, thereby keeps "on" position.
During "on" position, give tripping electromagnet 9 energisings, the magnetic core 92 of tripping electromagnet 9 moves downward, and drives end cover connecting rod 11 1 ends in the above and moves downward.Because connecting rod 11 is hinged on the framework 31, the nose 14 of stirring of connecting rod 11 moves upward simultaneously; Be inserted in the poke hole 37 owing to stirring nose 14 again, so dead bolt 34 inside retractions are stirred in the motion of connecting rod 11.When overlapping 32 li in the dead bolt 34 complete retractions, because lateral pin 13 has lost the resistance shelves, under the effect of spring 7 tension force, moving crane span structure 12 moves upward rapidly, and separating brake is finished in moving contact 2, fixed contact 4 separation.
