The normally closed or normally open of relay is entirely to rely on the effect of permanent-magnet steel.When the contact of relay needs to open or conjunction state
When, it is only necessary to just（Instead）DC pulse voltage excitation coil, relay are just completed out in moment and are converted with the state closed.
In actual use, there is a kind of magnetic latching relay to acting the stationary contact bounce time in attracting process and rebound
Number is relatively high, and conventional magnetic latching relay is worked as movable contact in movable contact spring and is closed to stationary contact, and contact surface generation is mutually touched
It hits, collision counter-force, which can recoil to movable contact, leads to repeatedly number shake occur between contact, and contact is unstable, affects the use of product
Performance and stability.
Invention content
In view of the deficienciess of the prior art, the utility model provides a kind of quiet spring of magnetic latching relay, on stationary plate
Quiet shrapnel is set if dashpot, between stationary plate and stationary contact, forms effective collision counter-force absorbing structure, when movable contact collides stationary contact
When, stationary contact is buffered to dashpot, and quiet shrapnel deforms upon, and is absorbed movable contact and is collided counter-force, effectively inhibits the rebound of quiet spring,
The shake number between contact is reduced, contact stabilization is improved.
To achieve the above object, the utility model provides following technical solution：A kind of quiet spring of magnetic latching relay, including
By riveting end riveted on the stationary contact riveted holes of quiet shrapnel, quiet shrapnel is logical for stationary contact, quiet shrapnel and stationary plate, wherein stationary contact
The riveting column riveted of two stationary plate riveted holes and stationary plate is crossed, is the dashpot of stationary plate, quiet shrapnel other one immediately below quiet shrapnel
End is suspended in dashpot top.
The quiet spring of a kind of magnetic latching relay described in the utility model, wherein stationary contact include contact bodies and riveting end.
The quiet spring of a kind of magnetic latching relay described in the utility model, wherein quiet shrapnel is a rectangle or horseshoe clamp plate, wherein
Right-angle side side symmetrically sets two stationary plate riveted holes, and the other end sets a stationary contact riveted holes, and end riveting is riveted with the stationary contact
It closes.
The quiet spring of a kind of magnetic latching relay described in the utility model, wherein stationary plate motion end upper surface set two in side
A rectangle or U-shaped shallow slot is arranged as dashpot, buffering in riveting column front with the stationary plate riveted holes riveted in riveting column
The size of the slot quiet shrapnel is big, and quiet shrapnel is suspended in dashpot top, forms collision counter-force absorbing structure.
Following beneficial effect is generated using the technical program：Traditional quiet spring is made of stationary plate and stationary contact, when dynamic
When stationary contact collides, stationary contact is hit, and larger bounce is generated, it may appear that the problem of quiet spring is shaken, this programme is quiet
It is additionally arranged a collision counter-force absorbing structure between piece and stationary contact, i.e., a quiet shrapnel is set between stationary plate and stationary contact, quiet
Riveting contacts are on quiet shrapnel, and quiet shrapnel one end is riveted on the riveting column of stationary plate, and the other end is suspended on the dashpot of stationary plate, when
When stationary contact is collided by movable contact, movable contact presses against stationary contact and pushes quiet shrapnel, quiet shrapnel that slight deformation occurs into dashpot,
Most of impact energy is absorbed, final quiet shrapnel springs back to normal condition, avoids the jitter phenomenon of routine intravenous spring, sound contact
Binding performance is stablized.
The utility model is further described below in conjunction with the accompanying drawings.
