Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection range of the present utility model with this.
As shown in Figure 1, the utility model is a kind of reinforced Straight pull magnetic latching relay.Comprise electromagnetic system and contact sets, also comprise Antimagnetic hood 31, Antimagnetic hood 32, electromagnetic system comprises case 1, upper cover 2, coil rack 5, the first yoke 7, the second yoke 6, iron core 8, connecting rod 9, terminal pin 10, the first pushing piece 11, the second pushing piece 12, auxiliary reed 131, auxiliary reed 132 and movable contact spring 15, coil rack 5 and the first yoke 7, the second yoke 6 is arranged on Antimagnetic hood 31, in the cavity that Antimagnetic hood 32 surrounds, Antimagnetic hood 31, Antimagnetic hood 32 is arranged in the cavity that case 1 and upper cover 2 surround, coil rack 5 middle parts are provided with magnet steel 41 and magnet steel 42, two magnet steel same polarities arrange in opposite directions, be all for example the S utmost point or be all the N utmost point, magnet steel 41 and magnet steel 42 form respectively a magnetic loop like this, connecting rod 9 is fixed in iron core 8, terminal pin 10 is through coil rack 5, iron core 8 inserts in coil rack 5, coil on coil rack 5 is connected with external power source by terminal pin 10, the first pushing piece 11 and connecting rod 9 snappings, the first 11 one-tenth of pushing pieces are Z-shaped, the first pushing piece 11 lower ends, right side are snapped with a balance slide block 14, the first pushing piece 11 is provided with 2 closed fulcrums 20, auxiliary reed 131 is provided with closing support 21.Closed fulcrum can increase contact force, reduces reed rebound.The second pushing piece 12 and the first pushing piece 11 snappings, the second pushing piece 12 and movable contact spring 15 snappings, auxiliary reed 131, auxiliary reed 132 is connected with movable contact spring 15, facilitate movable contact spring 15 playback, when the sense of current of coil changes, coil is because the pulsed current signal of moment produces magnetic field, the effect in magnetic field makes iron core 8 and connecting rod 9 to the first yoke 7 or the second yoke 6 direction motions, thereby drive the first pushing piece 11, the second pushing piece 12, auxiliary reed 131, auxiliary reed 132 and movable contact spring 15 move along iron core 8 equidirectionals, the first pushing piece 11 of similar lever makes balance slide block 14 move along the contrary direction of iron core 8 simultaneously, changed the state of relay, and before arriving, next pulse current signal remains on this position always.Thereby prevent iron core 8 when being subject to enormous impact (for example transportation or installation process in from 1 meter of falling from high altitude), because the effect of inertia makes the iron core 8 of relay with improper mode own shift position in coil rack, thereby avoided blasting because contact between contact is not firm, wait danger.Another effect of balance slide block 14 is that its operating position can be from directly reacting the state of current relay closes or disconnection in appearance.
Contact sets comprises moving plate combination and still combination, moving plate combination comprises moving spring abutment 19 and moving contact 16, moving spring abutment 19 is connected with movable contact spring 15, moving spring abutment 19 is provided with 3 sample line riveted holes 22, sample line is riveted on sample line riveted holes 22, and pass in the middle of 19 two semi arches of driven spring abutment, reduced the interference to sample line of magnetic field that electric current produces.Moving contact 16 is connected with movable contact spring 15, still combination comprises quiet spring abutment 18 and fixed contact 17, quiet spring abutment 18 is connected with fixed contact 17, when the first pushing piece 11, the second pushing piece 12, auxiliary reed 131, auxiliary reed 132 and movable contact spring 15 are to the first yoke 7 or second 6 directions whens motion of yoke, be connected in moving contact 16 on movable contact spring 15 near or away from the direction motion of fixed contact 17, thereby change the state of relay.
Magnetic latching relay is moving contact 16 when normal work, fixed contact 17 is closure state, the magnetic field of magnetic latching relay inside distributes as shown in Figure 2, when the sense of current of coil changes, coil is because the pulsed current signal of moment produces magnetic field as shown in Figure 3, the effect in magnetic field makes iron core 8 and connecting rod 9 to the second yoke 6 direction motions, thereby drive the first pushing piece 11, the second pushing piece 12, auxiliary reed 131, auxiliary reed 132 and movable contact spring 15 move along iron core 8 equidirectionals, iron core no longer contacts the first yoke 7 then tightly touches the second yoke 6, the moving contact 16 being connected on movable contact spring 15 moves to the direction away from fixed contact 17, therefore moving contact 16, fixed contact 17 becomes open mode.Moving contact 16, fixed contact 17 become after open mode, whole magnetic latching relay causes the variation of circuit, circuit is changed into open by pass before, and now the magnetic field of magnetic latching relay inside distributes as shown in Figure 4, and keeps this state before next pulse current signal.
When relay contact closure, iron core 8 is in coil rack 5 inner and upper, and balance slide block 14 is below balance slide block groove inside, otherwise, when relay contact disconnects, iron core 8 is below coil rack 5 inside, and balance slide block 14 is in balance slide block groove inner and upper.
The application of Antimagnetic hood 31, Antimagnetic hood 32 is all protected in Antimagnetic hood most important electromagnetic circuit, can cannot normally not use because being subject to strong magnetic disturbance.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
