Abstract
The invention provides a solenoid drive circuit breaker, relating to circuit switch control device technical field. A fixed contact is fixed in housing of the circuit breaker, a moving contact is mounted at relative position of the fixed contact. The moving contact is joined with a drive rotation shaft by a movement pair. One side of the housing is mounted with a solenoid drive device containing a moving core. The moving core is provided with a first and a second position, of which one end is hinged with a cam hinged in the housing by a connection rod to form a crank connection rod mechanism. One end of the moving contact far from the fixed contact is hinged with a rotation board of the drive shaft which is fixedly connected with the drive shaft and supported on the housing by the drive shaft. One side of rotation board of the drive shaft is mounted with a roller which forms a cam pair together with outline of the cam. When the moving core is respectively in the first and the second positions, outline of the cam is respectively corresponding to on and off positions of the moving contact. The invention is capable of implementing contact on and off function, which is the same as original circuit breaker, with structure greatly simplified, technical demand obviously reduced so as to effectively decrease production cost.
Description
Technical field
The present invention relates to a kind of circuit breaker, especially a kind of electromagnetic driven breaker belongs to connecting and disconnecting of the circuit control device technical field.
Background technology
Circuit breaker is a kind of connecting and disconnecting of the circuit control device commonly used.In the housing of existing circuit breaker fixed contact and the moving contact relative with fixed contact are housed, fixed contact is fixed in the housing, and moving contact then is connected with the driving rotating shaft by kinematic pair.Understand according to the applicant, existing typical moving contact of breaker need carry out drive controlling by spring operating mechanism, this mechanism adopts spring energy-storage usually, the principle that becomes five connecting rods of four link motions by complexity drives the rotating shaft rotation again, thereby realizes the separating brake of contact of breaker and combined floodgate (be referring to application number 93118936.5 Chinese patent application).Above-mentioned existing mechanism structure complexity, number of spare parts surpass 100 usually, and part process is required height, manufacture difficulty.
Summary of the invention
The objective of the invention is to: the problem at above prior art exists, by architecture advances, propose the simple electromagnetic driven breaker of a kind of mechanism, thereby significantly simplify the operation mechanism, reduce technology difficulty and manufacturing cost.
In order to reach above purpose, electromagnetic driven breaker of the present invention contains housing, and described housing internal fixation has fixed contact, and described fixed contact relative position is equipped with moving contact, and described moving contact is connected with the driving rotating shaft by kinematic pair; Its improvements are that described housing one side is equipped with the magnetic driving equipment that contains iron core; Described moving iron core has first and second positions, and the one end is hinged with the cam that hinge is contained in the housing by connecting rod, constitutes toggle; Described moving contact is hinged away from an end and the driving shaft flap of fixed contact, and described driving shaft flap and driving shaft are connected, and are supported on the housing by driving shaft; One side of the contiguous cam of described driving shaft flap is provided with and the bent wide roller that constitutes the cam pair of cam; When described moving iron core is in first and second positions respectively, the bent wide combined floodgate and the separating brake position of corresponding described moving contact respectively of described cam.
Like this, by the control of magnetic driving equipment by cam mechanism, the present invention can realize the contact divide-shut brake function identical with original circuit breaker, and structure is simplified greatly, to the also obviously reduction of requirement of part process, thereby effectively reduces manufacturing cost.

Embodiment
Embodiment one
Present embodiment as shown in Figures 1 to 3, housing 8 internal fixation have a pair of fixed contact 9, the relative position of fixed contact 9 is equipped with moving contact 6, and this moving contact is hinged by hinge pin 6.1 away from an end and the driving shaft flap 10 of fixed contact 9, has mounted back-moving spring 5 (referring to Fig. 3) on this hinge pin 6.1.Driving shaft flap 10 is connected with driving shaft 3, and is supported on the housing 8 by driving shaft 10.One side of housing is equipped with permanent magnet driving device 1.This permanent magnet driving device contains and can pass through the power-actuated moving iron core 1.1 of electromagnetic action, have and stretch out and two extreme positions of withdrawing, its outer end is hinged by pin 2.1 with the cam 2 that is installed in the housing 8 by connecting rod 4, constitute toggle, " slide block " that wherein moving iron core 1.1 is equivalent to move reciprocatingly, cam 2 is equivalent to " crank " that corner is accepted restriction.One side of driving shaft flap 10 contiguous cams 2 is provided with and the bent wide roller 3.1 that constitutes the cam pair of cam, and this roller is made of roller bearing pin and the roller that is enclosed within on this bearing pin.When moving iron core was in the extended and retracted position respectively, the bent wide of cam 2 made moving contact 6 be in combined floodgate, separating brake position (referring to Fig. 1 and the Fig. 2) that contacts, separates with fixed contact respectively by driving shaft flap 10.
During work, this breaker closing process is: moving unshakable in one's determination 1.1 in the permanent magnetic device 1 moves upward under the effect of electromagnetic force, move counterclockwise by connecting rod 4 driving cams 2 that connect with it, thereby driving shaft 3 is turned clockwise, the moving contact 6 of circuit breaker moves right, thereby dynamic and static contact is connected, breaker closing, the hinged hinge pin center of the hinged center of cam, roller centre and realization moving contact and driving shaft flap is on the same straight line at this moment, therefore can guarantee the stable contact of dynamic and static contact; The separating brake process is: moving unshakable in one's determination 1.1 in the permanent magnetic device 1 moves downward under the effect of electromagnetic force, moves clockwise by connecting rod 4 driving cams 2, and driving shaft 3 is rotated counterclockwise under the effect of fixed contact counter-force and back-moving spring 5.Make moving contact of breaker to left movement, thereby dynamic and static contact separate, breaker open operation, at this moment, roller 3.1 is in cam 2 bent wide recess, therefore can keep stable.
The permanent magnet mechanism of present embodiment is compared with conventional springs mechanism has following remarkable advantage:
In addition to the implementation, the present invention can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of requirement of the present invention.
