A high frequency relay has at least two drive terminal units arranged at an outer peripheral brim portion of at least two regions of three regions divided from a plane region of a base with a signal line. The base may be a plane triangle, plane square, plane hexagon, or a plane circle.

High frequency relay and its connection structure

A structure of a spring has a supporting member, an actuating member that is rotatably supported to the supporting member by a first supporting axis at a portion near a center, and a plurality of interlocking members that are each provided on both sides of the first supporting axis, that are rotatably supported to the supporting member by a second supporting axis, and that are rotatably coupled to the actuating member. Each point of action of the interlocking members is defined at a portion that is closer to the first supporting axis than to the coupled portion of the second supporting axis and the actuating member.

Structure of spring and actuator using the spring

A relay includes a permanent magnet and a magnetic circuit. The permanent magnet is disposed between a pair of electromagnets. The pair of the electromagnets is formed by winding coils around body portions of spools. Each spool has flanges integrally formed on both upper and lower end portions thereof. The magnetic circuit is formed by a yoke spanning the spools and the permanent magnet. The permanent magnet is held by the upper and lower flanges of a pair of the spools that are juxtaposed.

Relay

A relay includes a contact point block having a support shaft with both ends spanning a contact point base, a plunger having a movable contact at a lower end thereof, and a movable iron piece configured to drive the plunger and to have a plate spring. The relay also includes an electromagnetic unit and a base block having a fixed contact point at a position opposite to the movable contact point. The movable iron piece is supported on the supporting shaft. The plunger is inserted through an operation hole of the contact point base. Upper and lower surfaces of the contact point block are held by the electromagnetic unit and the base block. The electromagnetic unit directly fixes the iron core to an upper surface of the contact point base.

A relay driving a plunger includes a movable iron piece, and a movable contact point, and position restricting means. The movable iron piece is configured to rotate around a horizontal shaft center between a contact point base and an electromagnetic unit based on excitation and nonexcitation of an electromagnetic unit placed above the contact point base. The movable contact point is fixed to a lower end portion of the plunger protruding from a lower surface of the contact point base. The movable contact point is contacted with and separated from a fixed contact point. The position restricting means is provided on an upper surface side of the contact point base.

A relay includes a movable iron piece, a plate spring fixed to the one surface of the movable iron piece, a shaft hole formed by the one surface of the movable iron piece and the plate spring, and a supporting shaft inserted through the shaft hole. The movable iron piece is rotated round the supporting shaft based on excitation and nonexcitation of a magnetic unit. Both end portions of the plate spring alternately drive a contact point unit. The shaft hole is formed by a flat portion of the one surface of the movable iron piece and a bearing portion formed by subjecting the plate spring to bending work. The movable iron piece is supported so as to be rotatable.

An electromagnetic relay for high frequency signal switching is provided. The electromagnetic relay has a small size, high isolation characteristics, and small loss. Fixed terminals are supported by the sides of a base composed of a dielectric material and having an internal space. A fixed contact on each fixed terminal is exposed to the internal space. The surface of the fixed terminal is disposed parallel to the bottom of the base, while a movable block is disposed in the internal space of said base. Signal lines are formed from the fixed terminals and a movable contact piece. Shielding portions to be grounded are disposed at either upper or lower part of the internal space corresponding to the signal lines.

Electromagnetic relay

The present invention provides a terminal structure of a high frequency signal transmitting part which can enhance high frequency characteristics of high frequency signal transmitting terminals which are projected in the sideward direction from side faces of a casing of the high frequency signal transmitting part and are bent thereafter. In such a terminal structure, outer faces of the projected high frequency signal transmitting terminals are covered with extension portions of shielding plates in a non-contact state.

Terminal structure of high frequency signal transmitting part

Insulating walls and are arranged between fixed contacts and that face a movable contactor while being able to come in and out of contact with it and a shield plate positioned on the back surface side of the fixed contacts and With this arrangement, a compact high-frequency use switch having the desired high-frequency characteristic can be obtained with high productivity.

Switch for high frequency

In an electromagnetic relay in which a contact mechanism 50 provided on a base 10 is driven by a card 60 which slides and moves in parallel to the axis of an electromagnet block 20 provided in the base 10 as the electromagnet block 20 is magnetized and demagnetized, the base 10 comprises a guide portion 17 for restricting the card 60 in its position. This prevents variations in the performance characteristics so that high productivity and long service life of contacts can be obtained.
