Description
Technical field
The utility model relates to a kind of D.C. contactor more particularly to the gasket constructions and movable contact of a kind of D.C. contactor
System.
Background technique
D.C. contactor contact is generally divided into stationary contact and movable contact system, generally comprised in movable contact system movable contact,
Spring, axis, iron core etc., these parts are all mounted on an axle to form a system.For movable contact system, the work of spring
With critically important, actuation (i.e. magnet exciting coil is powered, contact contact), the reset (i.e. magnet exciting coil powers off, and contact disconnects), shape of contact
The holding of state is all influenced by spring.However, spring design when, be many times limited by materials and processes, spring it is interior
Diameter is all more much bigger than axis, in this way assembly when spring very big circumferential play is just had on axis, this will lead to movable contact by
Power is uneven, is easy to appear the phenomenon that movable contact skew, that contact contacts is unreliable, the contactor service life is low.
Summary of the invention
In order to overcome drawbacks described above, the utility model provides gasket construction and the movable contact system of a kind of D.C. contactor
System, prevent due to spring circumferential direction play it is excessive caused by movable contact unbalance stress.
The utility model is to solve technical solution used by its technical problem: a kind of gasket knot of D.C. contactor
The periphery of structure, including circular shim body, the shim body is equipped with several boss towards one side face interval.
Several boss and the shim body are integrally formed as a further improvement of the utility model,.
As a further improvement of the utility model, several boss from the peripheral portion region of the shim body to
It is formed after the bending of one side.
Several boss are vertical with the one side of the shim body as a further improvement of the utility model,.
Several boss are put down along parallel with the side of the shim body as a further improvement of the utility model,
The section in face is arc.
The boss is at least 3 as a further improvement of the utility model, and is uniformly distributed in the shim body
Periphery on.
The utility model also provides a kind of movable contact system of D.C. contactor, including gasket, transmission shaft, movable contact spring, iron
Core and spring, iron core are fixed on the lower end of transmission shaft, and movable contact spring is fixed on the upper end of transmission shaft, and spring pocket is set on transmission shaft simultaneously
Between movable contact spring and iron core, gasket is between spring and movable contact spring, it is characterised in that: the gasket is above-mentioned gasket
Structure, and the boss of the gasket is caught in the inner ring that several boss are formed towards the spring, and by the upper surface outer ring of spring.
As a further improvement of the utility model, between the upper side and transmission shaft of the movable contact spring and the iron
It is fixedly connected respectively by circlip between the downside and transmission shaft of core.
The beneficial effects of the utility model are: the gasket construction and movable contact system on gasket by increasing positioning step
That is boss effectively avoids the circumferential play of spring, avoids movable contact uneven by spring force, so as to cause movable contact skew, touching
The phenomenon that point contact is unreliable, the contactor service life is low improves the reliability and service life of contactor, while structure is simple,
Manufacture is realized conveniently.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is another viewing angle constructions schematic diagram of Fig. 1；
Fig. 3 is the utility model usage state diagram.
In conjunction with attached drawing, make the following instructions:
1 --- shim body；2 --- boss；
10 --- gasket；11 --- transmission shaft；
12 --- circlip；13 --- movable contact；
14 --- iron core；15 --- spring.
Specific embodiment
Below in conjunction with attached drawing, elaborate to a preferred embodiment of the utility model.But the guarantor of the utility model
Shield range is not limited to following embodiments, i.e., in every case with simple made by present utility model application the scope of the patents and description
Equivalent changes and modifications all still belong within the utility model patent covering scope.
It refering to fig. 1-3, is a kind of gasket construction of D.C. contactor described in the utility model, including circular gasket sheet
The periphery of body 1, the shim body is equipped with several boss 2 towards one side face interval.
Preferably, several boss and the shim body are integrally formed (such as punching press)；Several boss are by institute
The peripheral portion region of shim body is stated to being formed after the bending of one side；The side of several boss and the shim body
Face is vertical；Several boss are arc along the section of the plane parallel with the side of the shim body；The boss is at least
It is 3, and is uniformly distributed on the periphery of the shim body.
A kind of movable contact system of D.C. contactor, including gasket 10, transmission shaft 11, movable contact spring 13, iron core 14 and spring
15, iron core 14 is fixed on the lower end of transmission shaft 11, and movable contact spring 13 is fixed on the upper end of transmission shaft 11, and spring 15 is sheathed on transmission shaft
It goes up and is located between movable contact spring and iron core, gasket 10 is between spring 15 and movable contact spring.Wherein, the gasket 10 is above-mentioned
Gasket construction, and the boss of the gasket is towards the spring 15, and the upper surface outer ring of spring 15 is caught in several boss and is formed
Inner ring in；Distinguish between the upper side and transmission shaft of the movable contact spring and between the downside and transmission shaft of the iron core
It is fixedly connected by circlip 12.
When in use, refering to Fig. 3, the movable contact system of contactor is by gasket 10, transmission shaft 11, circlip for the gasket construction
12, movable contact 13, iron core 14 and spring 15 form, and the lower end of transmission shaft 11 is fixed on iron core 14, and the upper end of transmission shaft is used for
Movable contact 13 is installed, the upper side of movable contact 13 is fixedly connected by circlip 12 with transmission shaft 11, and the downside of movable contact is gasket
10 and spring 15, gasket 10 and spring 15 cover at the middle part of transmission shaft 11 simultaneously.Wherein, gasket 10 is using described in the utility model
Gasket construction, when installation, for the boss 2 of gasket 10 towards 15 side of spring, the outer ring of spring 15 is mounted on several boss (can
At least three or multiple is set) inner ring Lee, in this way, the inner ring of boss can limited spring 15 circumferential play, avoid moving
Contact discontinuity, so as to cause movable contact, crooked, contact contacts the disadvantages such as unreliable, the contactor service life is low, is connect with being promoted
The reliability and service life of tentaculum.
It can be seen that the gasket construction increases positioning step, that is, boss, the circumferential play of spring is effectively avoided, avoids dynamic touching
Point is uneven by spring force, and the phenomenon unreliable so as to cause movable contact is crooked, contact contacts, the contactor service life is low improves
The reliability and service life of contactor, while structure is simple, manufacture is realized conveniently.
