Abstract
It the utility model is related to contactor technical field, specifically, it is related to a kind of damping D.C. contactor, it includes stem, static contact positioned at stem lower end, the dynamic touch panel corresponding with static contact, the dynamic touch panel other end connection iron core of moving axis one end connection, it is dynamic that magnetic conductive board is provided between touch panel and iron core, buffering spacer is provided between iron core and magnetic conductive board.The utility model between dynamic iron core and magnetic conductive board by setting flexible buffering spacer, during so that dynamic iron core and magnetic conductive board colliding, caused bounce is smaller, effectively dynamic touch panel and static contact contact shake, strengthen the stability of contact, while improve service life.
Description
Technical field
Contactor technical field is the utility model is related to, specifically, is related to a kind of damping D.C. contactor.
Background technology
Contactor is divided into A.C. contactor (AC) and D.C. contactor (DC), and it is applied to electric power, distribution and electricity consumption.Contact
Device generally refers to flow through current induced magnetic field using coil, makes contact closure, to reach the electrical equipment of control load.
After contactor coil is powered, coil current can produce magnetic field, and caused magnetic field makes static iron core produce electromagnetic attraction
Attract dynamic iron core, and drive contactor point to act, normally opened contact closure.When the coil is de-energized, electromagnetic attraction is disappeared, and armature is being released
Put and discharge in the presence of spring, restore contact, normally opened contact disconnects.
Existing contactor, when normally opened contact closes, touch panel and static contact contact are moved, dynamic iron core is stopped when arriving magnetic conductive board upwards
Only, because dynamic iron core and magnetic conductive board are metal, meeting rigid collision has larger bounce-back, causes dynamic touch panel and static contact contact to be trembled
It is dynamic, energization performance is influenceed, and dynamic iron core and magnetic conductive board collision make a noise, and influence usage experience.
Utility model content
1st, technical problems to be solved
Make shake easily occur for dynamic touch panel and static contact contact and dynamic iron core collision magnetic conductive board sends loud noise etc.
Problem, the utility model provide a kind of damping D.C. contactor, and it can realize that dynamic/static contact contact shake is small, improve product
The service life of continuous disjunction work.
2nd, technical scheme
The purpose of this utility model is achieved through the following technical solutions：
A kind of damping D.C. contactor, including stem, the static contact positioned at stem lower end are corresponding with static contact
Dynamic touch panel, the dynamic touch panel other end connection iron core of moving axis one end connection are dynamic that magnetic conductive board, iron core and magnetic conduction are provided between touch panel and iron core
Buffering spacer is provided between plate.
Preferably, buffering spacer is attached to magnetic conductive board side.
Preferably, the material of buffering spacer is silicon rubber, thickness is 0.1~1mm.
3rd, beneficial effect
Compared to prior art, the utility model has the advantage of：
1st, a kind of damping D.C. contactor of the present utility model, when its continuous disjunction works, normally opened contact closes accordingly
Disconnect, when dynamic touch panel and static contact contact, iron core, which is moved upward to when buffering spacer contacts with iron core and magnetic conductive board, to be stopped, iron core
Flexible buffering spacer is collided, bounce-back is smaller, so that dynamic touch panel and static contact contact shake are smaller, energization performance is more
It is stable, so as to improve the life-span of the continuous disjunction work of product and preferable stability in use.
2nd, a kind of damping D.C. contactor of the present utility model, buffering spacer are fitted on the downside of magnetic conductive board, and iron core is transported upwards
Dynamic to encounter buffering spacer be elastic collision, and with small vibration, buffering spacer is bonded being connected firmly for contact area with magnetic conductive board.
3rd, a kind of damping D.C. contactor of the present utility model, buffering spacer patch are silicon rubber, and silicon rubber has preferable
High-temperature behavior, physical and mechanical properties and electric property, 0.1mm silicane rubber plate have preferable elastic performance, good vibration damping effect
Fruit.
