Abstract
Disclosed is a buffering structure between coils, yoke iron and a base board of an AC contactor, composed of the coils, E-shaped yoke iron and the base board. The coils are sheathed on the convex section in the middle of the E-shaped yoke iron, and the bottom surface of the E-shaped yoke iron and the base board are opposite between which a rubber part is positioned. The two longer side edges of the rubber part are extended upwards and inwards to form two pairs of wrapping sides respectively coated in the two concave sections of the E-shaped yoke iron. The utility model makes the vibration among the coils, the E-shaped yoke iron and the base board which is caused by the E-shaped yoke iron attracting E-shaped armature iron to be well cushioned and greatly reduces the negative influence brought by the vibration.

A.C. contactor is mainly used in the important power control member of control alternating current machine start-stop and other electrical load break-make, the basic principle of existing A.C. contactor is: comprise pedestal, top cover, base plate, relative E shape armature of direction and E shape yoke are installed in pedestal, be provided with reaction spring between E shape armature and the E shape yoke, be fixedly connected with contact supporting on the E shape armature, be elasticly connected with one or more bridge shape moving contacts on the contact supporting, pedestal is provided with and the corresponding one or more pairs of fixed contacts of bridge shape moving contact, and fixed contact links to each other with external connection end, is arranged with coil on the projection in the middle of E shape yoke, coil links to each other with control end, during use, external connection end inserts motor circuit, control end access control circuit, when coil electricity, E shape armature and E shape yoke be adhesive mutually under magneticaction, and bridge-shaped contact is communicated with fixed contact, constitutes path, make electric motor starting, on the contrary, coil blackout is under the effect of reaction spring, bridge-shaped contact and fixed contact separate, and the motor outage stops.According to different needs, A.C. contactor can be provided with one to three bridge shape moving contact and corresponding three pairs of fixed contacts, for use in load motor or three phase alternating current motor and other electrical load.
As from the foregoing, the action of A.C. contactor is mainly undertaken by E shape yoke and the mutual adhesive of E shape armature, when E shape yoke and the mutual adhesive of E shape armature, meeting produces collision and vibrates, thereby can drive the contact vibration and the generation contact secondary rebound starting the arc, cause the product loss of function, and can produce bigger electromagnetic noise.Therefore, need cushion above-mentioned vibration at some key position design buffer structures, yet existing A.C. contactor lacks the buffer structure of this respect.
The utility model content
The utility model provides the buffer structure between a kind of ac contactor coil, yoke and the base plate, and its main purpose bumps when being to overcome the mutual adhesive of E shape yoke and E shape armature and negative effect that the vibration that produces brings.
The utility model adopts following technical scheme: the buffer structure between ac contactor coil, yoke and the base plate, comprise coil, E shape yoke and base plate, coil is sheathed on the middle projection of E shape yoke, E shape yoke bottom surface is relative with base plate, be provided with a rubber parts between E shape yoke bottom surface and the base plate, two long lateral sections of this rubber parts upwards, extending internally forms two pairs of bound edges, and these two pairs of bound edges are wrapped in respectively on two recesses of E shape yoke.This rubber parts plays cushioning effect between E shape yoke bottom surface and base plate, its two pairs of bound edges play cushioning effect between coil and E shape yoke.
Extend upward around the aforesaid rubber parts and form a framework, this framework is wrapped in around the E shape yoke, base plate upwards forms some protuberances in the rubber parts location about, and this protuberance is provided with convex closure by the side of rubber parts, and this convex closure holds out against the lateral surface of the framework around rubber parts.Protuberance on the base plate and convex closure thereof are clamped in E shape yoke on the base plate, and the framework around the rubber parts plays cushioning effect between convex closure and E shape yoke.
Aforesaid coil is provided with and screws tight type power access end and blade inserting power access end, the type power access end of screwing tight comprises horizontally disposed plates and the screw that is screwed together on the plates, the blade inserting power access end vertically is arranged at a side that screws tight the type power access end, the opposite side that screws tight the type power access end is provided with a vertical limiting wall, vertically the limiting wall top edge extends to form a horizontal constraints wall to blade inserting power access end one side, this horizontal constraints wall is provided with the arc breach of stepping down by the side of blade inserting power access end, and the step down center of breach of this arc is aligned with each other with the center in the vertical direction that screws tight the screw of type power access end.The breach of stepping down on the horizontal constraints wall is an arc, rather than complete circle hole shape, thereby has reduced the difficulty of mould, has also reduced production cost.
By above-mentioned description to the utility model structure as can be known, compare with prior art, the utlity model has following advantage: the vibration that produces when one, the utility model makes between coil, E shape yoke and the base plate because of E shape yoke and E shape armature adhesive collision obtains good buffering, thereby reduces to vibrate the negative effect that brings; Two, the power access end of the utility model coil is reasonable in design, and the mould difficulty reduces, and production cost also reduces.
