Description
Technical field
The present invention relates to D.C. contactor technical field, more particularly to a kind of high power D.C. contactor movable contact knot
Structure.
Background technology
Electric automobile, quick charge stake, battery switching and high voltage direct current compress switch control etc. energy-conservation efficient direct current
Electrical equipment is widelyd popularize, especially electric automobile largely exploitation and use so that multiconductor group D.C. contactor product shows
Must be particularly important, the triggering of multigroup contact in the market directly uses two single movable contacts, due in mechanical structure
Deviation, the synchronism of multigroup contact closure is poor, causes starting difficulty.In addition, multigroup independent movable contact is also occupied and set
Count space so that the volume of D.C. contactor is bigger than normal, is not easy to install.
The content of the invention
The technical problems to be solved by the invention are：In order to overcome, multigroup stationary contact poor synchronization is not in the prior art
Foot, the present invention provide a kind of high power D.C. contactor movable contact structure.
The present invention solves its technical problem technical scheme to be taken：A kind of high power D.C. contactor movable contact
Structure, including two movable contact components, moving contact support and reset push rod, two movable contact components are radially symmetrically set in
The both sides for resetting push rod, and the movable contact component, reset push rod and the moving contact support integrated through injection molding.
Movable contact component due to resetting push rod both sides needs synchronization action, and movable contact component is along reset push rod radial direction
It is symmetrically arranged, therefore, it is necessary to ensure that movable contact component does not produce bias, then can ensure the synchronization action of movable contact component,
Moving contact support uses the plastic material of high intensity, by movable contact component and resets push rod and moving contact support integrated through injection molding, rises
The effect of centering has been arrived, so as to improve the uniformity of movable contact component action, has improved the reliability of D.C. contactor；In addition, adopt
With two groups of movable contact components are installed on a push rod, reduce the parts used, save space, reduce D.C. contactor
Volume.
In order to further improve the uniformity of movable contact component action, along the reset push rod shaft on the moving contact support
To provided with reset push rod guide pin bushing, and it is described reset push rod be placed in it is described reset push rod guide pin bushing in.Reset is extended using guide sleeve
Push rod and the contact area of moving contact support in the axial direction, are further ensured that the center superposition for resetting push rod and movable contact component,
Play certralizing ability.
Pushing away along reset push rod axial direction can be produced because movable contact component with stationary contact when contacting, between sound contact
Power, it is injection connection to reset push rod and moving contact support, therefore, axial direction is not produced with moving contact support to ensure to reset push rod
Movement, the part that is placed in the moving contact support of push rod that resets circumferentially is equipped with spacing ring.Can by spacing ring
Axial movement is produced between push rod and moving contact support to avoid resetting, further improves reliability.
Further, the movable contact component includes dynamic touch panel, tracking push rod and tracking spring, the tracking push rod upper end with
The dynamic touch panel center is fixedly connected, the tracking push rod lower end and the moving contact support integrated through injection molding, the tracking spring
It is sheathed on the tracking push rod between the dynamic touch panel and the moving contact support.
Dynamic touch panel can produce abrasion after frequently being contacted with stationary contact, in order to ensure being abutted against for dynamic touch panel and stationary contact
Touch, upward elastic force is produced using tracking spring, promote dynamic touch panel and stationary contact reliable contacts.
Pushing away along tracking push rod axial direction can be produced because movable contact component with stationary contact when contacting, between sound contact
Power, tracking push rod are injection connections with moving contact support, therefore, axial direction are not produced with moving contact support to ensure to track push rod
Movement, the part that is placed in the moving contact support of tracking push rod is circumferentially equipped with spacing ring.Can by spacing ring
Axial movement is produced between push rod and moving contact support to avoid tracking, further improves reliability.
The beneficial effects of the invention are as follows：A kind of high power D.C. contactor movable contact structure provided by the invention, move and touch
Point support uses the plastic material of high intensity, by movable contact component and resets push rod and moving contact support integrated through injection molding, serves
The effect of centering, so as to improve the uniformity of movable contact component action, improve the reliability of D.C. contactor；In addition, using one
Two groups of movable contact components are installed on individual push rod, reduces the parts used, saves space, reduce the body of D.C. contactor
Product.
