Description
Technical field
The present invention relates to a kind of circuit breaker, particularly a kind of operating mechanism of circuit breaker.
Background technology
The operating mechanism of current circuit breaker generally adopts external handle strip to move breaker operator, and passes through the position of jogging switches measurement handle thus the splitting or integrating lock state of acquisition circuit breaker, realizes circuit breaker and the operation of splitting or integrating lock by the mechanism of complexity.This kind of mode has following shortcoming:
1, when operating mechanism handle strip moves circuit breaker interlock, because handle has the operation arm of force, be thus difficult to make the contact of multipole circuit breaker to close simultaneously.
2, need perforate on shell when the operating grip of operating mechanism swings, thus operating mechanism cannot be completely enclosed within shell, does not possess the characteristic preventing solid granulates from entering.
3, sensitive switch volume is comparatively large, is unfavorable for the miniaturization of operating mechanism.
Summary of the invention
The object of the invention is to provide a kind of operating condition being reached testing agency by transducer detection magnet detection position to solve above-mentioned the deficiencies in the prior art, simplified the design of operating mechanism by the design of innovation, thus this operating mechanism can load in the shell being no more than 18mm width (2 moduluses) simultaneously.The operating mechanism of a kind of circuit breaker of the synchronism of the consistency of breaker operator, stability and contact closure is achieved by the mode of built-in interlock.
To achieve these goals, the operating mechanism of a kind of circuit breaker designed by the present invention, it is characterized in that: it comprises band tooth rotating disk, drive block, transmission mechanism and circuit board, band tooth rotating disk is arranged between drive block and circuit board, described band tooth rotating disk comprises arc-shaped groove, the circular hole of hollow, inductor and two projections, arc-shaped groove is between two projections, inductor is arranged on the projection upper end of band tooth rotating disk, inductor and projection lay respectively at is with tooth rotating disk both sides, described drive block is provided with mounting rod, first boss and the second boss, mounting rod is positioned at drive block center, described circular hole is passed and both movable cooperations in this mounting rod one end, the other end coordinates fixing with transmission mechanism, the first described boss and the second boss are positioned at together diametrically, second boss is provided with groove, motion bar and the first magnetic block are installed in this groove, motion bar is placed on arc-shaped groove, and be active between two projections, described circuit board is provided with transducer.
Preferably, described sensor setting has three, and three transducers distribute on circuit boards respectively.
The operating mechanism of a kind of circuit breaker that the present invention obtains, has following characteristics: 1, operating mechanism and spell circuit breaker and adopt Inner link, product construction is in complete closed state, improves product degree of protection, can not increase product height simultaneously; 2, adopt the transmission mechanism of band tooth driven by rotary disc moving block, structure is simple; 3, adopt the running position of transducer detecting mechanism, be conducive to the volume reducing mechanism.

Embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
Embodiment:
As shown in Figures 1 to 5, the operating mechanism of a kind of circuit breaker provided by the invention, comprising:
A band tooth rotating disk 1, described band tooth rotating disk 1 can, by engaging with worm screw (not shown) or gear (not shown) the power obtaining operating mechanism, wherein be with tooth rotating disk 1 be provided with two projections 11 and be assemblied on shell together with drive block 2.Band tooth rotating disk 1 promotes drive block 2 by projection 11 when rotating and realizes forward or reverse.Band tooth rotating disk 1 is provided with an arc-shaped groove 12 and places inductor 13, by the turned position of inductor 13 detection zone tooth rotating disk 1.
A drive block 2, described drive block 2 is provided with the first boss 21 and the second boss 22, opposite side is provided with the groove 22 of hole and the fixed magnetic part 23 linked with circuit breaker, described drive block 2 is assemblied on shell (not shown) by the cylinder of drive block with band tooth rotating disk 1, and freely can rotate between two projections 11 of band tooth rotating disk 1; Described magnetic block 23 is for the position detecting drive block and rotate thus obtain the position of the handle of the circuit breaker linked with drive block.Drive block 2 is equipped with the magnetic of a mounting rod 24 for conduct magnetism block, is convenient to transducer 31 and responds to, described circular hole is passed and both movable cooperations in this mounting rod 24 one end, and the other end coordinates fixing with transmission mechanism.
A circuit board 3, the transducer 31 that on described circuit board 3, diverse location is provided with two or more quantity for the position of inductor 13 and magnetic part 23, thus obtains the turned position of band tooth rotating disk and drive block.
A transmission mechanism 4, described transmission mechanism 4 is contained on described drive block 2, drives transmission mechanism 4 to rotate, thus drive breaker actuation when drive block 2 rotates.
Be described further for above-mentioned: band tooth rotating disk 1 is contained on shell together with drive block 2, freely rotate between two projections 11 making drive block 2 be in band tooth rotating disk 1, band tooth rotating disk 1 drives drive block 2 to rotate within the specific limits by projection 12, drive block 2 drives transmission mechanism 4 to rotate, transmission mechanism 4 and circuit breaker handle (not shown) coaxial line rotate, thus drive the action of circuit breaker (not shown).
The course of work of the operating mechanism of this patent, band tooth rotating disk 1 rotates and drives drive block 2 to rotate, thus drives breaker actuation, when circuit breaker is in combined floodgate or open position, magnet rotors on moving block to the top of different sensors 31, thus determines the splitting or integrating lock state of circuit breaker.When circuit breaker reaches closing position, band tooth rotating disk 1 is by reverse rotation, and the position of transducer 31 induced magnet 11, when band tooth rotating disk 1 turns to certain position, band tooth rotating disk 1 stops the rotation, and now circuit breaker can free separating brake.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention; without departing from the inventive concept of the premise; its framework form can be flexible and changeable, just makes some simple deduction or replace, all should be considered as belonging to the scope of patent protection that the present invention is determined by submitted to claims.
