As is apparent from the above description, according to the first aspect of the present invention, two electrically independent movable contact pieces respectively contact two electrically independent fixed contacts. Therefore, a relay that can open and close two circuits at the same time is obtained. In addition, a coil plate that generates a magnetic flux is located between the pair of plate-shaped cores and the movable contact plate to form a closed magnetic path. Therefore, all of the magnetic flux generated in the coil plate jumps over the space between the iron core of the plate-shaped core and the movable contact piece. The direction is the same as the moving direction of the movable contact piece. As a result, there is no leakage of magnetic flux,
Since all the magnetic flux in the space can be used for the attraction force for driving the movable contact piece, the magnetic efficiency is high. Further, since the plate-shaped core, the coil plate, and the movable contact plate have a layer structure that can be sequentially stacked and assembled, the assembly is easy and the assembly accuracy is high. For this reason, a thin and small relay having no variation in operation characteristics can be obtained. And since the magnetic conduction part is shared with the electric conduction part, the number of parts,
Low man-hours for assembly and high productivity. According to the second and third aspects of the present invention, since both the movable contact and the fixed contact are arranged at the tip of the protrusion, the magnetic flux is concentrated and a relay having high magnetic efficiency can be obtained. According to the fourth aspect of the present invention, the plate-shaped core is electrically connected to the connection end of the contact terminal exposed from the bottom surface of the box-shaped base. According to the fifth aspect of the present invention, since the thin beam portion and the movable contact piece of the movable contact plate are cut out of the resin thin plate on which the conductive magnetic material thin film is formed, the unit cost of the component is low, and the component accuracy and the assembly accuracy are high. A relay is obtained. According to the sixth aspect of the present invention, the movable contact pieces extend from the pair of parallel thin plate beams made of the conductive magnetic material, and the movable contact pieces are integrated by abutting each other via the insulating material.
For this reason, the movable contact plate is formed of one member,
The assembly work when assembling the movable contact plate to the base is simplified. According to the seventh aspect of the present invention, the movable contact piece moves in an inclined state and comes into contact with the fixed contact. For this reason,
The movable contact is less likely to be welded to the fixed contact, and even if it is welded, it is easily separated. According to the invention of claim 8, a pair of insulated electric paths is formed by providing a thin film made of a conductive magnetic material on one surface of one resin thin plate. For this reason, a relay having high insulation and sealing properties can be obtained. According to the ninth aspect of the present invention, the upright portion located near the movable contact plate is formed by bending and raising at least one side edge of the plate-shaped core. Therefore, there is an effect that the leakage of the magnetic flux is reduced, the magnetic resistance is reduced, and the magnetic efficiency is improved.
