Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1, the present invention is a kind of Straight pull magnetic latching relay, comprises electromagnetic system and contact sets, also comprises Antimagnetic hood 31, Antimagnetic hood 32, electromagnetic system comprises case 1, upper cover 2, coil rack 5, first yoke 7, second yoke 6, iron core 8, connecting rod 9, terminal pin 10, first pushing piece 11, second pushing piece 12, auxiliary reed 131, auxiliary reed 132 and movable contact spring 15, coil rack 5 and the first yoke 7, 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, magnet steel 41 and magnet steel 42 is provided with in the middle part of coil rack 5, two pieces of magnet steel same polarities are arranged in opposite directions, be all such as S pole or be all N pole, such magnet steel 41 and magnet steel 42 form a magnetic loop respectively, 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 snapping, the second pushing piece 12 and the first pushing piece 11 snapping, second pushing piece 12 and movable contact spring 15 snapping, auxiliary reed 131, auxiliary reed 132 is connected with movable contact spring 15, movable contact spring 15 is facilitated to playback, when the sense of current of coil changes, coil is due to the pulsed current signal generation magnetic field of moment, the effect in magnetic field makes iron core 8 and connecting rod 9 to the first yoke 7 or the motion of the second yoke 6 direction, thus drives the first pushing piece 11, second pushing piece 12, auxiliary reed 131, auxiliary reed 132 and movable contact spring 15 move along iron core 8 equidirectional, change the state of relay, and remain on this position before next pulse current signal arrives always.
Contact sets comprises moving plate combination and still combination, moving plate combination comprises dynamic spring abutment 191, dynamic spring abutment 192 and moving contact 16, dynamic spring abutment 191, dynamic spring abutment 192 is connected with movable contact spring 15, 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, second pushing piece 12, auxiliary reed 131, when auxiliary reed 132 and movable contact spring 15 are to the first yoke 7 or the motion of the second yoke 6 direction, the moving contact 16 be connected on movable contact spring 15 moves to close or away from fixed contact 17 direction, thus 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 due to moment pulsed current signal produce magnetic field as shown in Figure 3, the effect in magnetic field makes iron core 8 and connecting rod 9 move to the second yoke 6 direction, thus drive the first pushing piece 11, second pushing piece 12, auxiliary reed 131, auxiliary reed 132 and movable contact spring 15 move along iron core 8 equidirectional, iron core no longer contacts the first yoke 7 then tightly touches the second yoke 6, the moving contact 16 be 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.After moving contact 16, fixed contact 17 become open mode, whole magnetic latching relay causes the change 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.
The application of Antimagnetic hood 31, Antimagnetic hood 32 makes most important electromagnetic circuit all protect in Antimagnetic hood, cannot normally can not use because being subject to strong magnetic disturbance.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
