Claims

[Claims for Utility Model Registration] (1) A yoke whose sides are generally L-shaped is connected to an iron core so that the sides are generally U-shaped, and a protrusion is formed at the free end of the yoke to face each other across a notch. , an electromagnetic block in which the free end of the iron core serves as a magnetic pole part, and the opposing protrusions serve as opposing magnetic pole parts; and a permanent magnet block in which two opposing pieces of magnetic material sandwich a permanent magnet from both ends in the direction of magnetization. The two blocks are combined so that the two magnetic pieces enter into the notch and the free end of the iron core fits between the two magnetic pieces, and the coil and permanent magnet work together. in,
The permanent magnet block moves in the forward and reverse directions within the notch so that the free end of the core moves in the opposite and forward directions relative to each other between the two magnetic pieces, and this movement is caused by the contact drive. The relay is a polarized relay in which the information is transmitted to a contact mechanism to open and close the contacts, and the contact mechanism is provided on the side of the electromagnetic block where the free end of the core is located at the axial end of the coil, and A polarized relay characterized in that the permanent magnet block does not extend outside the yoke. (2) The electromagnetic block is fixed to the body so that the yoke faces the body with the iron core in between, and the fixed contacts and movable contacts of the contact mechanism face each other from the body toward the protrusion at the free end of the yoke. The fixed terminal and plate spring that extend
The polarized relay according to claim 1, wherein the polarized relays are supported so as to face each other. (3) The polarized relay according to claim 1 or 2, wherein the yoke and the iron core are integrally formed from a single plate.
