Description
Technical field
The utility model belongs to Low Voltage Electrical Apparatus, particularly a kind of contactor.
Background technology
Contactor is divided into A.C. contactor and D.C. contactor, and it is applied to electric power, distribution and electricity consumption.Contactor broadly refers in industrial electro and utilizes coil to flow through current induced magnetic field, makes contact closure, to reach the electrical equipment of control load.
In electrotechnics; because fast shut-off can exchange with direct current major loop and the device controlling (some type can reach 800 amperes) circuit with big current can be connected continually; also can be used as controlling work factory and establish electrical load such as standby ﹑ electricity hot device ﹑ machine-tool and various kinds electric power unit etc. as control system so often apply to motor resembling ﹐; contactor can not only be connected and cut off circuit, but also has the effect of low-voltage release guard.Contactor control capability is large, is applicable to frequent operation and far distance controlled.It is one of critical elements in automatic control system.
Current most of contactor coil lug plate is all under seat, and pedestal steps down generally can not to winding wiring sheet, and general winding wiring screw of only giving is stepped down.Generally have two kinds of situations for a kind of Foundation Plate of Contactor element portion, one is its base of unsplit bedplate version and base plate is overall structure form, and another kind is nonintegrated structure, and its base and base plate are single part.No matter to be overall structure or its main contact excess of stroke dimension chain of nonintegrated structure form should be by pedestal, bobbin, supporter, up and down iron core, contact support, these parts of dynamic/static contact.Excess of stroke dimension chain can't pass through base or winding wiring sheet.When assembling based on its pedestal of certain contactor of this principle analysis and base, pedestal first contacts with winding wiring sheet, and winding wiring sheet inserts in bobbin groove, is pressed down past for bobbin by extruding coil lug plate.In this case winding wiring sheet is by pedestal crimp, and bobbin lug plate draw-in groove also can be crushed out of shape.The another kind of form that has excess of stroke dimension-chain analysis causes excess of stroke dimension-chain analysis to increase many uncertain factors.Not only be not easy to the control of parameter, more affect the quality of product.
Utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of contactor, mainly solves existing contactor at assembling process coil lug plate by the problem of pedestal crimp.
The technical scheme that the utility model adopts is:
A kind of contactor, comprise interconnective base and pedestal, described base and described pedestal opposite face are provided with bobbin, rubber supporter has been compressed bottom described bobbin, described bobbin circumference is also respectively equipped with the first coil lug plate, second winding wiring sheet and tertiary coil lug plate, described first coil lug plate, second winding wiring sheet and tertiary coil lug plate include the terminals that external part and described external part extend to form downwards, described base is provided with the holding tank for accommodating described terminals, the opposite face of described pedestal and described base is provided with and described first coil lug plate, the external part adaptation of the second winding wiring sheet and tertiary coil lug plate forms the escape groove of matched in clearance.
Described bobbin is provided with some inserting grooves, and one end of described first coil lug plate, the second winding wiring sheet and tertiary coil lug plate coordinates with described inserting groove grafting.
Described first coil lug plate and the second winding wiring sheet are wholely set.
Described base material is that thermoplastic is made.
Gap is provided with between the lower surface of the first coil lug plate, the second winding wiring sheet and tertiary coil lug plate and described base opposite face.
The beneficial effects of the utility model are: the utility model provides a kind of contactor, comprise interconnective base and pedestal, base and pedestal opposite face are provided with bobbin, rubber supporter has been compressed bottom bobbin, bobbin circumference is also respectively equipped with the first coil lug plate, second winding wiring sheet and tertiary coil lug plate, the opposite face of pedestal and base is provided with and the first coil lug plate, the external part adaptation of the second winding wiring sheet and tertiary coil lug plate forms the escape groove of matched in clearance, the first coil lug plate is realized by escape groove, second winding wiring sheet and tertiary coil lug plate can not be interfered, such winding wiring sheet can not be bent, therefore winding wiring sheet mounting groove also can not be out of shape because of stressed, structure is simple, result of use is good.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail: as shown in the figure, a kind of contactor, comprise interconnective base 1 and pedestal 2, described base 1 and described pedestal 2 opposite face are provided with bobbin 11, rubber supporter 5 has been compressed bottom described bobbin 11, described bobbin 11 circumference is also respectively equipped with the first coil lug plate 111, second winding wiring sheet 112 and tertiary coil lug plate 113, described first coil lug plate 111, second winding wiring sheet 112 and tertiary coil lug plate 113 include the terminals that external part 114 and described external part 114 extend to form downwards, described base 1 is provided with the holding tank 12 for accommodating described terminals, described pedestal 2 is provided with and described first coil lug plate 111 with the opposite face of described base 1, external part 114 adaptation of the second winding wiring sheet 112 and tertiary coil lug plate 113 forms the escape groove 21 of matched in clearance.Winding wiring sheet is located at because pedestal does not compress, fundamentally eliminating in excess of stroke dimension-chain analysis process the extra many uncertain factors increased, avoiding in assembling process because of problem that pedestal causes coil rack lug plate draw-in groove to be out of shape by extruding lug plate simultaneously.The utility model provides a kind of contactor, comprise interconnective base and pedestal, base and pedestal opposite face are provided with bobbin, rubber supporter has been compressed bottom bobbin, bobbin circumference is also respectively equipped with the first coil lug plate, second winding wiring sheet and tertiary coil lug plate, the opposite face of pedestal and base is provided with and the first coil lug plate, the external part adaptation of the second winding wiring sheet and tertiary coil lug plate forms the escape groove of matched in clearance, the first coil lug plate is realized by escape groove, second winding wiring sheet and tertiary coil lug plate can not be interfered, such winding wiring sheet can not be bent, therefore winding wiring sheet mounting groove also can not be out of shape because of stressed, structure is simple, result of use is good.
