An electromagnetic relay and a terminal block each include a voltage converter. The voltage converter is located adjacent to a coil and electrically connected to first coil terminals and second coil terminals. The voltage converter converts a power supply voltage input through one of the first coil terminals to a set value different from the input power supply voltage and outputs the power supply voltage to an electromagnet through one of the second coil terminals.

Electromagnetic relay and terminal block

A relay includes a relay main body () including a base () having a first surface (), and a relay substrate () extending, in a direction intersecting the first surface (), from a second surface () on the opposite side of the base () from the first surface (), the relay substrate () being united with the base (), and a case () attached to the relay main body () to cover the relay substrate (), and the case () being filled with sealant. The relay main body () includes a board connector () provided on the first surface () of the base (), an electronic component mounting portion () provided on the relay substrate (), a conducting portion () provided on respective surfaces of the base () and the relay substrate (), and an electronic component () mounted on the electronic component mounting portion ().

Relay

The movable body includes a pivot and a contact portion. The pivot is rotatably supported. The contact portion is disposed at a position contactable with a contact piece. The movable body rotates around the pivot and presses the contact piece via the contact portion to move the second contact close to the first contact. The actuator presses the movable body to rotate the movable body around the pivot. The contact piece has a curved portion located between the second contact and the support. The pivot is located on a side where the support is disposed with respect to the curved portion. The actuator includes a pressing member which presses the movable body. The pressing member moves in an axial direction of the pressing member to press the movable body.

The pressing member is configured to move to an off-position and an on-position. When the pressing member is located at the off-position, the first contact and the second contact come into a non-contact state. When the pressing member is located at the on-position, the first contact and the second contact come into a contact state by press of the pressing member against the contact piece. The actuator moves the pressing member from the off-position to the on-position via an overshoot position located beyond the on-position. The contact piece includes a body, and a low rigidity portion having rigidity lower than rigidity of the body. The pressing member presses the low rigidity portion.

An electromagnetic device includes a spool having a cylindrical body with a through hole, a secondary coil formed in a spiral shape along an outer peripheral surface of the cylindrical body and formed with a closed circuit by metal plating, and a primary coil formed of a conductive wire wound around the secondary coil via an insulating material covering the secondary coil. An induced current, generated by applying a voltage to any one of the primary coil and the secondary coil, is allowed to flow to the other coil different from the one coil.

An electronic device where molten solder does not come into contact with a sealant so as not to destroy a sealing function. An electronic device is provided with: an insulating base mounted on a printed circuit board; a common planar terminal provided so as to extend from an outer side surface to a bottom surface edge of the insulating base, and cause electrical continuity between the outer side surface and the bottom surface edge of the insulating base; a cover fitted to the insulating base and covering the common planar terminal; and a sealant sealing a gap between the outer side surface of the insulating base and an inner circumferential surface of the cover. A solder pool is formed in a position surrounded by the printed circuit board and the common planar terminal at the bottom surface edge of the insulating base.

Electronic device

An electromagnetic relay () has high wear resistance, high corrosion resistance, and good magnetic properties. The electromagnetic relay () includes a magnetic component including an alloy layer on its surface formed by diffusion-coating of at least one element selected from the group consisting of Cr, V, Ti, and Al. The alloy layer has a thickness of 5 to 60 &#x3bc;m, inclusive.
