Abstract
A quick make mechanism used in a small-scaled breaker includes a lever, a moving contact, a sliding block and two shafts. In the initial stage of quick make, the moving contact moves around the two different shafts and the upper part of the moving contact moves to the edge position of the sliding block along a straight line under the blocking of the sliding block. When the moving contact moves forward, the upper part of the moving contact will be released by the sliding block and rotates around the fixing shaft quickly, and the moving contact connects quickly to realize the quic make of the contact. After the tripping of the small-scaled breaker, the moving contact moves toward the break position and the upper part of the moving contact pushes the sliding block upwards, and back to the break position. After the resetting of the moving contact, the sliding block is reset under the action of the spring.
Description
Technical field
The present invention relates to a kind of miniature circuit breaker, refer in particular to a kind of fast closing mechanism that is used for miniature circuit breaker.
Background technology
In the prior art, there is not fast closing mechanism in the miniature circuit breaker mostly; Even if in the miniature circuit breaker that fast closing mechanism is arranged on a small quantity, also there are problems such as complex structure, assembling difficulty in used fast closing mechanism, particularly, have influence on the normal use of this miniature circuit breaker on the contrary because the structure of this miniature circuit breaker that has a fast closing mechanism is quite complicated.
Summary of the invention
The objective of the invention is to design the fast closing mechanism of a kind of dependable performance, miniature circuit breaker simple in structure.After this fast closing mechanism is installed on miniature circuit breaker, when contact is soon closed, can lean on mechanical energy storage quick-make contact, make the operation of relevant manpower become the operation of irrelevant manpower.
According to technical scheme provided by the invention, the fast closing mechanism of described miniature circuit breaker comprises lever, moving contact and slide block, it is characterized in that: the lower end of lever utilizes the middle part of bearing pin and moving contact hinged, the middle part of lever is articulated on the main shaft, and the upper end of moving contact can be attached to the side slip of slide block; Shifting lever, make lever when main shaft rotates, the upper end of moving contact is in the side slip that stops the lower edge slide block of slide block; After the upper end of moving contact slided down to the disengaging slide block, moving contact rotated around bearing pin rapidly, and moving contact and fixed contact are connected rapidly, realized the quick-make of moving contact and fixed contact; After miniature circuit breaker was threaded off, moving contact moved to open position, and the upper end of moving contact is upwards pushed slide block open, gets back to open position.
Slide block is positioned at shell, and slides up and down in the stopper slot on being arranged at shell, between slide block and shell spring is arranged, and slide block is close to lower end position under the effect of spring.Moving contact can rotate around bearing pin; End near the upper end on moving contact is provided with stop surface, and when miniature circuit breaker was in open position, the stop surface of moving contact leaned against on the main shaft, and moving contact moves to the direction away from fixed contact under the effect of spring.
During along the side slip of slide block, the stop surface that moving contact leans against on the main shaft just leaves main shaft, slides into the lower limb position of slide block up to moving contact in the upper end of moving contact.Upwards push open in the process of slide block in the upper end of moving contact, when the upper end move up to leave slide block after, slide block resets under the effect of spring, gets back to lowest positions, moving contact is got back to open position.
This advantage is: simple and reliable for structure, be easy to realize, and be easy to assembling.

Embodiment
Figure 1 shows that the three-dimensional explosive view of the fast closing mechanism of miniature circuit breaker, comprise lever 3, moving contact 11, slide block 18, main shaft 7, axle 8.Slide block 18 is spacing by the stopper slot that is arranged on the shell, can only slide up and down, and spring (drawing among the figure) is arranged between slide block 18 and shell, and at ordinary times, slide block 18 is close lower end position under the effect of spring.Moving contact 11 and lever 3 are articulated in axle 8, and moving contact can be around axle 8 rotations, and when miniature circuit breaker was in open position, moving contact 11 had a stop surface 11 " lean against on the main shaft 7, moving contact 11 moves to the direction away from fixed contact under the effect of spring.Main shaft 7 was grown in the upper end 11 ' of moving contact 11, and can act on slide block 18, realized the quick-make of moving contact 11.
Moving contact 11 rivets together with tripping part 6 usefulness tubular rivets with lever 3, lever 3, and is free to rotate each other behind the riveted; The main shaft 7 of lever 3 is fixed on the shell.
In operating mechanism and free tripping mechanism, connecting rod 4 directly acts on the end face 3 ' of lever 3, tripping part 6 is close this end face 3 ' under the torsion spring effect, there is a location notch 6 ' can pin connecting rod 4 on the tripping part 6, connecting rod 4 is positioned between lever 3 and the tripping part 6, if connecting rod 4 is not pushed aside by external force by the effect of tripping part 6 or tripping part 6, then connecting rod 4 can slide along end face 3 ' when closed, and can skid off this face, promptly realize the trip free of mechanism; Tripping part 6 and lever 3 are got back to open position around same main shaft 7 rotations under the effect of spring 9; Behind trip free, connecting rod 4 can be under the pressure of the face 5 ' on the handle 5 resets and resets smoothly with the rotation of handle 5.
Actuating handle 5, driving lever 3 by connecting rod 4 rotates around main shaft 7, driving moving contact 11 again rotates around bearing pin 8, and rectilinear motion is done in the upper end 11 ' of moving contact 11 in the side that stops lower edge slide block 18 of slide block 18, this moment, moving contact 11 leaned against stop surface 11 on the main shaft 7 " just leave main shaft 7; slide to the lower limb position of slide block 18 up to moving contact 11 '; when handle 5 moves forward; rotate around bearing pin 8 rapidly with regard to breaking away from slide block 18 upper end 11 ' of moving contact 11; moving contact 11 is connected rapidly with fixed contact, realizes the quick-make of dynamic/static contact; After miniature circuit breaker is threaded off, moving contact 11 moves to open position, when running into slide block 18, the upper end 11 ' of moving contact 11 upwards pushes slide block open, move to after its end 11 ' leaves slide block 18 at moving contact 11, slide block 18 resets under the effect of spring, get back to lowest positions, moving contact 11 is got back to open position.
