A linked slide block of a main contact and an assistant contact at the front side and the rear side of a contactor is provided with the upper hinged shaft of a connecting rod; the shell wall of the lower parts of the front slide block and the rear slide block of the contactor is provided with a double-crank hinged shaft provided with double cranks; the double cranks are provided with the lower hinged shaft of the connecting rod; the upper hinged shaft of the connecting rod and the lower hinged shaft of the connecting rod at the front side and the rear side are both hinged with a connecting rod; the connecting rods at the front side and the rear side, the linked slide block of a main contact and an assistant contact at the front side and the rear side of the contactor, and the double cranks mutually form a double-crank mechanism with double connecting rods and double slide blocks; the shaft axis of the double-crank hinged shaft and the centre line of the double cranks intersect on one point; the shaft axis of the lower hinged shaft of the connecting rod slightly deviates from the centre line of the double crank made of magnetic material; the connection base of the shell of the main contact system is in an inverse U-shaped structure along the front and back direction; the inner wall of the U-shaped groove is provided with a groove-type electromagnet permanent seat; and electromagnet is fixed in the groove of the electromagnet permanent seat.

Description

A kind of vertical AC contactor
Technical field
The present invention relates to a kind of A.C. contactor, the energy-conservation noise elimination A.C. contactor of especially a kind of vertical electromagnetism.
Background technology
At present; The vertical AC contactor is universal very wide on the market; The electromagnetic system of A.C. contactor need continue still after adhesive could guarantee the operate as normal of A.C. contactor to the solenoid power supply that this A.C. contactor is owing to need to continue energising; So the electromagnetic system temperature is high, at first cause the useful life of contactor short; Simultaneously, the solenoid of A.C. contactor is under "on" position, and current noise is also very high, and noise pollution is serious, poor working environment.The 3rd, the solenoid of A.C. contactor continues energising, also wastes a large amount of electric energy, if with the whole additions of electric energy of the contactor waste of all power consumption equipments of the whole nation, should be equivalent to an ability that big power station generates electricity.Therefore, designing a kind of vertical electromagnetic type ability noise elimination A.C. contactor, is the present technical issues that need to address.
Summary of the invention
Technical problem to be solved by this invention provides a kind of vertical electromagnetic energy-saving noise elimination A.C. contactor.
The technical scheme that the present invention solves its technical problem is:
A kind of vertical AC contactor comprises main contacts system and auxiliary contact system, and the slide block of the main contacts of both sides and auxiliary contact interlock is provided with hinge on the connecting rod before and after the contactor; The housing wall of two side slide bottoms is provided with the double crank hinge before and after the contactor; Before and after contactor, be hinged with double crank on the double crank hinge of both sides, double crank is provided with the connecting rod down hinge, on hinge on the connecting rod of both sides, front and back and connecting rod down hinge, all is hinged with connecting rod; The slide block and the double crank of the main contacts of both sides and auxiliary contact interlock constitute double crank double link double-slider mechanism jointly before and after the connecting rod of both sides, front and back and the contactor; The axial line of double crank hinge and the center line of double crank intersect at a point, and the axial line of connecting rod down hinge departs from the center line of double crank a little, and the material of double crank is a magnetic material; The Connection Block of the housing of main contacts system along fore-and-aft direction for falling " U " type structure; The inwall of " U " groove of falling is provided with slot type electromagnet holder, at the groove internal fixation of slot type electromagnet holder the electromagnet that has coil tension spring is arranged, and the groove face of the outer cylinder of electromagnet and electromagnet holder is slidingly matched; The end face of electromagnet is higher than the end face of electromagnet holder when normality; The end face of electromagnet holder is provided with sensitive switch, and the end face of sensitive switch is lower than the end face of electromagnet when normality, gets when pressing start button QA contactor coil J and electromagnet; The double crank of double crank double link double-slider mechanism rotated around the double crank hinge when auxiliary contact adhesive of contactor drove main contacts system closure; Because the inertia of double crank motion, electromagnet bounced back in the groove of electromagnet holder when the connector of double crank was held by electromagnet, and the connector of double crank touches sensitive switch solenoid J dead electricity in the electromagnet retraction; Electromagnet under the effect that itself carries spring from newly getting back to the normality position; This moment, double crank double link double-slider mechanism was near lower dead point position, and contactor coil J gets into attracting state under cold state, reach the purpose of economize on electricity; Electromagnet dead electricity when pressing stop button QT, contactor is got back to reset condition.
Compared with prior art, energy-conservation more than 99%, the noiseless of the present invention, long service life.

Embodiment
As shown in the figure; A kind of vertical AC contactor; Comprise main contacts system and auxiliary contact system, the slide block of the main contacts of both sides and auxiliary contact interlock is provided with hinge 7 on the connecting rod before and after the contactor, and the housing wall of two side slide bottoms is provided with double crank hinge 8 before and after the contactor; Before and after contactor, be hinged with double crank 4 on the double crank hinge 8 of both sides; Double crank 4 is provided with connecting rod down hinge 5, on hinge on the connecting rod of both sides, front and back 7 and connecting rod down hinge 5, all is hinged with connecting rod 6, the main contacts of the connecting rod 6 of both sides, front and back and both sides, contactor front and back and the slide block of auxiliary contact interlock and double crank 4 common formation double crank double link double-slider mechanisms; The center line of the axial line of double crank hinge 8 and double crank 4 intersects at a point; The axial line of connecting rod down hinge 5 departs from the center line of double crank 4 a little, and the material of double crank 4 is a magnetic material, the Connection Block of the housing of main contacts system along fore-and-aft direction for falling " U " type structure; The inwall of " U " groove is provided with slot type electromagnet holder 1; Groove internal fixation at slot type electromagnet holder 1 has the electromagnet 3 that has coil tension spring, and the groove face of the outer cylinder of electromagnet 3 and electromagnet holder 1 is slidingly matched, and the end face of electromagnet 3 is higher than the end face of electromagnet holder 1 when normality; The end face of electromagnet holder 1 is provided with sensitive switch 2, and the end face of sensitive switch 2 is lower than the end face of electromagnet 3 when normality.
