Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is 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 Straight pull magnetic latching relay, comprise electromagnetic system and contact sets, also comprise Antimagnetic hood 31, Antimagnetic hood 32, electromagnetic system comprises case 1, loam cake 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 loam cake 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, for example all be the S utmost point or all be the N utmost point, magnet steel 41 and magnet steel 42 form respectively a magnetic loop like this, connecting rod 9 is fixed in the iron core 8, terminal pin 10 passes coil rack 5, iron core 8 inserts in the coil rack 5, coil on the coil rack 5 is connected with external power source by terminal pin 10, the first pushing piece 11 and connecting rod 9 snappings, 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, make things convenient for 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 so that iron core 8 and connecting rod 9 to the motion of the first yoke 7 or the second yoke 6 directions, 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, changed the state of relay, and before the next pulse current signal arrives, remained on this position always.
Contact sets comprises moving plate combination and still combination, the moving plate combination comprises moving spring abutment 191, moving spring abutment 192 and moving contact 16, moving spring abutment 191, moving spring abutment 192 is connected with movable contact spring 15, moving contact 16 is connected with movable contact spring 15, the 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 during to the motion of the first yoke 7 or the second yoke 6 directions, be connected on the movable contact spring 15 moving contact 16 near or away from the motion of the direction of fixed contact 17, thereby change the state of relay.
Magnetic latching relay is moving contact 16 when normal operation, 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 so that iron core 8 and connecting rod 9 move to the second yoke 6 directions, 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 that is connected on the movable contact spring 15 moves to the direction away from fixed contact 17, therefore moving contact 16, fixed contact 17 becomes open mode.After moving contact 16, fixed contact 17 become open mode, whole magnetic latching relay causes the variation of circuit, circuit is changed into open by pass before, and this moment, the magnetic field of magnetic latching relay inside distributed as shown in Figure 4, and kept this state before the next pulse current signal.
The application of Antimagnetic hood 31, Antimagnetic hood 32 can can't normally not used because being subject to strong magnetic disturbance so that most important electromagnetic circuit is all protected in Antimagnetic hood.
The above only is 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., all should be included within the protection range of the present utility model.
