The present invention provides an electromagnet device including a horizontal portion of a yoke arranged near one end portion of an iron core, a movable iron piece which pivotably supported on a leading end edge portion of a vertical portion of the yoke which serves as a fulcrum, an end portion of the movable iron piece adapted to be attracted to a magnetic pole portion by a main magnetic circuit, the magnetic pole portion is arranged in the other end portion of the iron core. The main magnetic circuit is formed by applying a voltage to a coil wound around a periphery of the iron core and an auxiliary magnetic circuit formed in parallel with the main magnetic circuit, the auxiliary circuit including a permanent magnet is arranged near the one end portion of the iron core and a magnetic resistance portion, in which a magnetic flux of the permanent magnet is magnetically saturated.

Electromagnet device

A high-frequency relay includes: a base block having fixed terminals insert-molded to expose fixed contacts; an electromagnetic block mounted on the base block and for rotating a movable iron piece due to excitation and demagnetization; and movable blocks interlocking with a rotation operation of the movable iron piece so as to be connected with and disconnected from the fixed contacts of the base block. A push-in spring for pushing one of the movable blocks is provided in the movable iron piece. The push-in spring includes a fixed portion fixed to the movable iron piece, a pressure portion for applying pressure to the movable block, and foot portions each extending substantially perpendicularly to the movable block wherein extending directions of the foot portions cane be adjusted.

High-frequency relay

A high-frequency relay includes: a base block having fixed terminals insert-molded to expose fixed contacts on the upper surface; an electromagnetic block having a coil wound around an iron core through a spool; and mounted on the base block, and movable blocks having movable contacts driven in accordance with excitation and demagnetization of the electromagnetic block so as to be connected with and disconnected from the fixed contacts of the base block. The movable blocks have movable iron pieces to be connected with and disconnected from the fixed contacts of the fixed terminals. A return spring is provided for elastically supporting each of the movable blocks so as to make the movable block accessible vertically to the upper surface of the base block. The return spring is disposed to be biased to one of the fixed terminals.

A relay of the present invention comprises a coil plate,having at least one layer of spiral flat coil,formed around each of a pair of holes,and fixed contacts,and movable contacts which are opposed to each other contactably and separably via the holes,in the coil plate,The fixed contacts,are provided on one side of each of a pair of flat core blocks,juxtaposed and insulated from one another. The movable contacts are provided on one movable contactor,which is supported so as to be drivable along a direction of plate thickness via at least one hinge portion,extending from a support member,for a movable contact plate

Relay

Electromagnetic relay and its manufacture

An electromagnetic relay of the present invention has a large dielectric strength between a coil and each contact because of an insulative member interposed therebetween. Even if the straight distance between the coil and each contact is small, it is possible to obtain a sufficient dielectric strength without an extra process. Moreover, since a leg part of the coil terminal is coated with an insulative resin, the dielectric strength between the coil terminal and a movable iron element or a movable contact piece is enhanced. An insertion window formed in an insulating plate of the coil helps to insert a thickness gauge with high positioning accuracy.
