Abstract

The invention relates to a negative magnetostriction control relay device and belongs to the field of electrical devices. The device comprises a negative magnetostrictive material, a first permanent magnet material, a first fixed yoke, a second fixed yoke, an armature, two springs and two contacts. According to the principle that the magnetic conductivity of the negative magnetostrictive materialis changed under pressure, by changing the magnetic flux in a permanent magnet material-negative magnetostrictive material loop, changing the magnetic flux in a permanent magnetic material-armature loop and then changing magnetic force borne by the armature to make the armature be in contact with the contacts, the function of switching on a circuit is achieved. Compared with a traditional electromagnetic relay, the device has the advantages that a power supply which controls the circuit to be switched on / off is avoided, and the device can be maintained in an on state.

Description

technical field [0001] The invention relates to a negative magnetostrictive control relay and belongs to the field of electrical devices. Background technique [0002] Discovered in 1842, the magnetostrictive effect is the effect of length and volume changes of ferromagnetic materials and ferrimagnetic materials due to changes in their own magnetization states. Among them, positive magnetostriction means that the material elongates along the direction of the magnetic field during the magnetization process, and negative magnetostriction means that the material shortens along the direction of the magnetic field during the magnetization process. As an important smart material, magnetostrictive materials have the advantages of high mechanical energy-electrical energy conversion efficiency and high energy density, and are widely used in aerospace, ships, electrical devices, audio and other fields. [0003] SmMF x As a negative magnetostrictive material, the magnetostrictive str...
