Abstract
Disclosed is a magnetic latching relay contact system capable of shortening the closure bounce time. The magnetic latching relay contact system comprises a stationary piece, a damping piece, a stationary contact, a movable contact, an R-type conducting piece, and a spring assembly. One end of the R-type conducting piece is fixedly connected with the spring assembly, and the other end of the R-type conducting piece is the free end. The movable contact is riveted to the free end. A receding site is arranged at one end of the stationary piece. The damping piece corresponding to the receding site is riveted to the longitudinal edge of the receding site. The stationary contact is riveted to the damping piece and makes movable contact with the movable contact. The magnetic latching relay contact system is novel in design and reasonable in structure; according the previous design, a stationary contact is directly riveted to a stationary piece which is used as a fixed body, and therefore the bouncing magnitude is large; according to the design of the magnetic latching relay contact system, the damping piece is added to be riveted to the stationary piece, the stationary contact is riveted to the damping piece, and the stationary contact is flexible and capable of swinging, so that the closure bounce time is greatly shortened, and the working reliability of a relay is improved.
Description
Technical field
The present invention relates to a kind of relay, especially a kind of have the magnetic latching relay contact system reducing closed bouncing time.
Background technology
Magnetic latching relay, that the magnetic force that a kind of closed or off-state is only produced by the permanent magnet in coil magnetic circuit system keeps, closed with off-state between mutual conversion only rely on the coil in the excitation coil of the DC pulse voltage forward or backwards magnetic circuit system of one fixed width after cause the driving member action of armature component action linkage and the electric control device that completes.
In the ordinary course of things, the fixed contact of relay is riveted on still, and still is fixed body, when moving contact contacts with fixed contact, because fixed contact is fixing, thus sound contact is clashed into, in the extremely short time, sound contact can be separated, closed, if and now have electric current to pass through, then can arcing thus have larger damage to contact, as contact adhesion, after the galvano-cautery of contact, contact resistance is bigger than normal causes temperature rise higher, thus greatly reduces life-span and the reliability of relay.
Summary of the invention
The object of the invention is by setting up vibration damping sheet, thus a kind of contact system with the magnetic latching relay reducing closed bouncing time is provided, improve the reliability of relay.
For achieving the above object, the technical solution used in the present invention is:
There is the magnetic latching relay contact system reducing closed bouncing time, comprise still, vibration damping sheet, fixed contact, moving contact, R type conducting strip and spring assembly; One end and the spring assembly of described R type conducting strip are affixed, and the other end is free end, and it rivets moving contact; Described still one end is provided with a clearance position, the vibration damping sheet that the riveted joint of the longitudinal edge of this clearance position has to correspond to described clearance position, and on this vibration damping sheet, riveted joint has fixed contact, and described fixed contact moves with moving contact and contacts.
Preferably, described vibration damping sheet is fexible conductor.
Preferably, described clearance position is a through hole or a groove.
The present invention is novel in design, rational in infrastructure, design is before all that fixed contact is directly riveted on still, and still is as a fixed body, thus spring is all comparatively large, and the design is then that increase vibration damping sheet is riveted on still, fixed contact is riveted on vibration damping sheet, such dead point is also flexible swingable, thus reduces closed bouncing time greatly, promotes the functional reliability of relay.
Accompanying drawing explanation
Fig. 1 is stereogram of the present invention;
Fig. 2 is explosive view of the present invention;
Fig. 3 is the vertical view of still of the present invention.
In figure, each label respectively: (1) still, (2) vibration damping sheet, (3) fixed contact, (4) moving contact, (5) spring assembly, (6) conducting strip, (7) clearance position.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail:
Referring to Fig. 1,2 and 3, a kind of have the magnetic latching relay contact system reducing closed bouncing time, comprises still 1, vibration damping sheet 2, fixed contact 3, moving contact 4, R type conducting strip 6 and spring assembly 5; One end and the spring assembly 5 of described R type conducting strip 6 are affixed, and the other end is free end, and it rivets moving contact 4; Described still 1 one end is provided with a clearance position 7, described clearance position is a through hole, the longitudinal edge riveted joint of this clearance position has one to correspond to the vibration damping sheet 2 of described clearance position, described vibration damping sheet is fexible conductor, on this vibration damping sheet 2, riveted joint has fixed contact 3, described fixed contact 3 contacts with moving contact 4 is dynamic, the structural design of above, have on elastically-deformable vibration damping sheet 2 due to fixed contact 3 is arranged at, when moving contact 4 comes in contact with fixed contact 3, fixed contact 3 can flexiblely swing, thus reduces closed bouncing time greatly, promotes the functional reliability of relay.
