An electromagnet device has a spool having a guard portion at at least one end thereof, a coil wound around a body portion of the spool, and a coil terminal press-fitted in the guard portion. A lead wire of the coil is tied up to a tying-up portion of the coil terminal projected from the guard portion. The tying-up portion is folded toward the guard portion of the spool after the lead wire of the coil is tied up to the tying-up portion of the coil terminal extending in a direction receding from the spool.

Electromagnet device and electromagnetic relay using the same

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

The present invention provides an electromagnet device including: an electromagnet block having a spool around which a coil is wound and an iron core inserted in a central hole of the spool; a yoke connected to an end portion of the iron core via a permanent magnet; a movable iron piece pivotably supported on a pivoting shaft center located at an end face edge portion of the yoke, the movable iron piece is adapted to pivot on a basis of magnetization and demagnetization of the electromagnet block, and a protrusion having a linear edge portion which extends in parallel to the pivoting shaft center and the protrusion protrudes from at least either the movable iron piece or the iron core, the protrusion protrudes in a facing direction in which the movable iron piece and the iron core face each other.

The present invention provides an electromagnet device which can obtain a desirable attraction force (retention force) between an iron core and a movable iron piece, a method of assembling the electromagnet device and an electromagnetic relay using the electromagnet device, the electromagnet device including an electromagnet block having the iron core being wound by a coil and an auxiliary yoke fixed to one end portion of the iron core, a yoke connected to the one end portion of the iron core via a permanent magnet, the movable iron piece pivotably supported on a pivoting shaft center (serving as a fulcrum) located in an end face edge portion of the yoke so that the movable iron piece pivots on a basis of magnetization and demagnetization of the electromagnet block, where the permanent magnet is located on an extension line of an axial center of the iron core and is interposed between the auxiliary yoke and the yoke.

Electromagnet device, method of assembling the same, and electromagnetic relay using the same

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

An optical element that realizes light path conversion of transmitting light at low loss, allows easy incorporation of functions such as light convergence or the like, and can be easily made into a compact size includes upper and lower main surfaces of a light path converting element of a plane shape are facing each other, and a light incoming surface and a light outgoing surface are adjacent surfaces at about 90 degrees. A curved light path converting surface is formed so as to face the light incoming surface and the light outgoing surface. Light coming in from the light incoming surface repeats full reflection between the upper main surface and the lower main surface and goes on, and is reflected by the light path converting surface, thereby the light path thereof is converted, and light is ejected from the light outgoing surface.

Optical element and optical device using the same

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.
