Abstract
The invention provides a movable contact structure for a high-power DC contactor. The movable contact structure comprises two movable contact assemblies, a movable contact bracket and a reset push rod, wherein the two movable contact assemblies are symmetrically arranged at two sides of the reset push rod along the radial direction; and the movable contact assemblies, the reset push rod and the movable contact bracket are injected into a whole. According to the movable contact structure for the high-power DC contactor provided by the invention, the movable contact bracket is made of a high-strength plastic material; and the movable contact assemblies, the reset push rod and the movable contact bracket are injected into a whole to play a centering role, so that the consistency of actions of the movable contact assemblies is improved; and the reliability of the DC contactor is improved. Furthermore, two movable contact assemblies are arranged on one push rod, so that used parts are reduced; the space is saved; and the volume of the DC contactor is reduced.
Description
Technical field
The present invention relates to D.C. contactor technical field, particularly relate to a kind of high power D.C. contactor moving contact structure.
Background technology
Wideling popularize of the energy-conservation efficient direct current power consumption equipments such as electric automobile, quick charge stake, battery switching and high-voltage dc voltage switch control rule, especially electric automobile is developed in a large number and is used, multiconductor group D.C. contactor product is made to seem very important, the triggering of many groups contact in the market directly adopts two independent moving contacts, due to the deviation in mechanical structure, the synchronism of many groups closing of contact is poor, causes starting difficulty.In addition, organize independently moving contact more and also occupy design space, make the volume of D.C. contactor bigger than normal, be not easy to install.
Summary of the invention
Technical problem to be solved by this invention is: in order to overcome the deficiency of many group fixed contact poor synchronization in prior art, the invention provides a kind of high power D.C. contactor moving contact structure.
The present invention solves the technical scheme that its technical problem will adopt: a kind of high power D.C. contactor moving contact structure, comprise two moving contact assemblies, moving contact support and reset push rod, two described moving contact assemblies are radially symmetrically set in the both sides of described reset push rod, and described moving contact assembly, reset push rod and described moving contact support integrated through injection molding.
Because the moving contact assembly of reset push rod both sides needs synchronization action, and moving contact assembly is arranged along reset push rod radial symmetric, therefore, need to ensure that moving contact assembly does not produce bias, then can ensure the synchronization action of moving contact assembly, moving contact support adopts the plastic material of high strength, by moving contact assembly and reset push rod and moving contact support integrated through injection molding, serve the effect of centering, thus improve the consistency of moving contact assembly action, improve the reliability of D.C. contactor; In addition, adopt on a push rod and two groups of moving contact assemblies are installed, decrease the parts of use, save space, reduce the volume of D.C. contactor.
In order to improve the consistency of moving contact assembly action further, described moving contact support is axially arranged with reset push rod guide pin bushing along described reset push rod, and described reset push rod is placed in described reset push rod guide pin bushing.Adopt fairlead to extend reset push rod and moving contact support contact area in the axial direction, ensure the center superposition of reset push rod and moving contact assembly further, play certralizing ability.
Because moving contact assembly is when contacting with fixed contact, can produce between sound contact along reset push rod shaft to thrust, reset push rod and moving contact support are that injection moulding is connected, therefore, in order to ensure that reset push rod and moving contact support do not produce axial movement, the part that described reset push rod is placed in described moving contact support is circumferentially equipped with spacing ring.Can avoid producing between reset push rod and moving contact support moving axially by spacing ring, improve reliability further.
Further, described moving contact assembly comprises dynamic touch panel, follows the tracks of push rod and tracking spring, described tracking push rod upper end is fixedly connected with described dynamic touch panel center, described tracking push rod lower end and described moving contact support integrated through injection molding, described tracking spring is sheathed on the described tracking push rod between described dynamic touch panel and described moving contact support.
Dynamic touch panel can produce wearing and tearing after frequently contacting with fixed contact, in order to ensure the reliable contacts of dynamic touch panel and fixed contact, adopting tracking spring generation elastic force upwards, promoting dynamic touch panel and fixed contact reliable contacts.
Because moving contact assembly is when contacting with fixed contact, can produce between sound contact along follow the tracks of push rod shaft to thrust, following the tracks of push rod is that injection moulding is connected with moving contact support, therefore, in order to ensure that tracking push rod and moving contact support do not produce axial movement, the part that described tracking push rod is placed in described moving contact support is circumferentially equipped with spacing ring.Can avoid producing between tracking push rod and moving contact support moving axially by spacing ring, improve reliability further.
The invention has the beneficial effects as follows: a kind of high power D.C. contactor moving contact structure provided by the invention, moving contact support adopts the plastic material of high strength, by moving contact assembly and reset push rod and moving contact support integrated through injection molding, serve the effect of centering, thus improve the consistency of moving contact assembly action, improve the reliability of D.C. contactor; In addition, adopt on a push rod and two groups of moving contact assemblies are installed, decrease the parts of use, save space, reduce the volume of D.C. contactor.
