Description
Technical field
The present invention relates to a kind of microminiature electromagnetic relay.
Background technology
At present, microminiature electromagnetic relay market provided generally comprises shell and is located at shell
Interior magnetic circuit system and contact system, magnetic circuit system includes bobbin, iron core, coil, yoke
And armature, iron core is positioned at the installation cavity of bobbin, and coil is arranged on the outer wall of installation cavity,
Contact system includes movable contact spring and the static contact spring piece of band stationary contact of band movable contact, and movable contact alignment is quiet
Contact, armature is located on movable contact spring, and movable contact is located at movable contact spring one end, and the movable contact spring other end sets
Having back-moving spring, static contact spring piece to be connected with bobbin, this microminiature electromagnetic relay movable contact spring is
Carry out return by back-moving spring, and back-moving spring the most easily produces deformation and without subtracting
Shake effect, structural stability is not good enough, it addition, the movable contact of above-mentioned microminiature electromagnetic relay and
The equal only one of which of stationary contact, in use the temperature of contact is higher, is unfavorable for that microminiature electromagnetism continues
The heat radiation of electrical equipment, reduces service life.
Summary of the invention
In view of the deficiency of background technology, the technical problem to be solved is to provide a kind of knot
The microminiature electromagnetic relay that structure stability is more preferable and service life is longer.
Realize to this end, the present invention adopts the following technical scheme that:
A kind of microminiature electromagnetic relay, the magnetic circuit system including shell and being located in shell and connecing
The system of touching, magnetic circuit system includes bobbin, iron core, coil, yoke and armature, contact system
Including movable contact spring and the static contact spring piece of band stationary contact of band movable contact, iron core is positioned at the installation of bobbin
Intracavity, coil is arranged on the outer wall of installation cavity, and static contact spring piece is connected with bobbin, its coil
Frame side is provided with support, and pedestal upper end is located at by yoke, and movable contact spring is the metal of " L " type bending
Shell fragment, and movable contact spring is fixed on support, armature is fixed on movable contact spring another side and holds in the mouth
Ferrum alignment iron core, movable contact is located on the movable contact spring of alignment stationary contact.
Movable contact spring afterbody on one side has bifurcated, and the two ends of bifurcated are equipped with movable contact, quiet spring
Sheet is two, and bobbin is provided with baffle plate, and baffle plate is positioned at above movable contact.
Support outer wall surrounds insulation board.
After using technique scheme, movable contact spring is the metal clips of " L " type bending, can make
For a part for path, movable contact spring self band elasticity instead of back-moving spring, and structural stability is more
Good, and movable contact and stationary contact are two, reduce the temperature of contact when using, make extra small
The service life of type electromagnetic relay is longer.
Accompanying drawing explanation
Fig. 1 is that the sectional structure schematic diagram of the present invention is intended to；
Fig. 2 is the perspective view that the present invention removes shell.
Detailed description of the invention
Shown in seeing figures.1.and.2, the microminiature electromagnetic relay that the present invention provides includes shell
1 and the magnetic circuit system be located in shell 1 and contact system, magnetic circuit system include bobbin 2,
Iron core 3, coil 4, yoke 5 and armature 6, contact system includes the dynamic spring of band movable contact 7
The static contact spring piece 10 of sheet 8 and band stationary contact 9, iron core 3 is positioned at the installation cavity 11 of bobbin 2,
Coil 4 is arranged on the outer wall of installation cavity 11, and static contact spring piece 10 is connected with bobbin 2, coil
Frame 2 side is provided with support 12, and support 12 upper end is located at by yoke 5, and movable contact spring 8 is " L "
Type bending metal clips, can as a part for path, and movable contact spring 8 be fixed on prop up
On frame 12, armature 6 is fixed on movable contact spring 8 another side and armature 6 is directed at iron core 3, disconnected
During road, the elasticity of movable contact spring 8 self can make armature 6 reset, and movable contact 7 is located at alignment stationary contact
On the movable contact spring 8 of point 9, the afterbody of movable contact spring 8 has bifurcated 13, the two of bifurcated 13
Being equipped with movable contact 7 on end, static contact spring piece 10 is two, when the increase of contact can reduce use
The temperature of contact, bobbin 2 is provided with baffle plate 14, and baffle plate 14 is positioned at above movable contact 7,
Can block movable contact spring 8, support 12 outer wall surrounds insulation board 15.
In the present embodiment, movable contact spring 8 is the metal clips of " L " type bending, can be as logical
The part on road, movable contact spring 8 self band elasticity instead of back-moving spring, and structural stability is more preferable,
And movable contact 7 and stationary contact 9 are two, reduce the temperature of contact when using, it addition,
Movable contact 7 is arranged over baffle plate 14, prevents crossing senior general's movable contact 7 because of movable contact spring elastic force and withstands on
On shell 1, be also prevented from simultaneously armature 6 from iron core 3 too away from and cannot fit.
