One end of the second movable member 32 in the second direction Y is rotatably connected to the iron core 41 of the electromagnet portion 40, which will be described later. The other end of the second movable member 32 in the second direction Y faces the suction portion 43 of the electromagnet portion 40, which will be described later. The second movable member 32 is separated from the suction portion 43 in the first direction X by a spring member 34 provided at a connection portion between one end of the second movable member 32 in the second direction Y and the iron core 41 of the electromagnet portion 40.

Therefore, the first movable contact 14 of the first contact mechanism 10 is in contact with the first fixed contact 13, and the second movable contact 24 of the second contact mechanism 20 is separated from the second fixed contact 23.

In this specification, except for FIG. 1, the cover 60 is not shown.

According to the electromagnetic relay 1, the following effects can be exhibited.

In the electromagnetic relay 1, a virtual straight line extending along the first direction X when the first contact mechanism 10, the second contact mechanism 20, and the electromagnet portion 40 are viewed along the second direction Y intersecting the arrangement surface 51. They are arranged in series on L at intervals. Further, the movable portion 30 is arranged between the first contact mechanism 10 and the second contact mechanism 20 on the virtual straight line L and in the first direction X, and is connected to the first movable contact piece 12 and the second movable contact piece 22. The first movable member 31 and the second movable member 32 arranged on the virtual straight line L and connected to the electromagnet portion 40, and the first movable member 31 and the second movable member 31 extending in the first direction X on the virtual straight line L. It has a third movable member 33 for connecting the movable member 32. With such a configuration, it is possible to realize an electromagnetic relay 1 having two contact mechanisms that can be miniaturized in the third direction Z intersecting the first direction X and the second direction Y.

The main body portion 311 in which the first movable member 31 extends along the second direction Y and one end of the second direction Y is rotatably supported by the base 50, and the other end of the main body portion 311 in the second direction Y. The first movable contact piece 12 and the second movable contact piece 22 have a holding portion 312 that sandwiches and holds the other end of the second direction Y in the first direction X. With such a configuration, it is possible to easily realize an electromagnetic relay 1 provided with two contact mechanisms that can be miniaturized in the third direction Z. Further, since the first contact mechanism 10, the second contact mechanism 20, the movable portion 30, and the electromagnet portion 40 can be installed on the arrangement surface 51 of the base 50 from the same direction in the second direction Y, it has high assembleability. An electromagnetic relay 1 having two contact mechanisms can be realized.

The electromagnetic relay 1 can also be configured as follows.

In the present disclosure, the first contact mechanism, the second contact mechanism, the movable part, and the electromagnet part are serialized on a virtual straight line extending along the first direction when viewed along the second direction intersecting the arrangement surface. It can be applied to electromagnetic relays of any configuration arranged at intervals. For example, the first movable member 31, the second movable member 32, and the third movable member 33 constituting the movable portion 30 are not limited to the above-described embodiment, and other configurations may be adopted.

As shown in FIG. 5, the movable portion 30 has an L-shape in which the end portion 331 connected to the second movable member 32 of the third movable member 33 bends in the second direction Y in a direction approaching the arrangement surface 51. May be configured to have. With this configuration, the number of turns of the coil of the electromagnet unit 40 can be increased, and the suction force of the suction unit 43 can be increased. As a result, the electromagnet portion 40 can be miniaturized, so that a miniaturable electromagnetic relay 1 having two contact mechanisms can be realized.

As shown in FIG. 6, the electromagnet portion 40 may be installed on the base 50 in a state of being inclined in the direction away from the first contact mechanism 10 in the first direction X as it moves away from the base 50 in the second direction Y. .. For example, when viewed along the third direction Z, the straight line orthogonal to the arrangement surface 51 is L0, and the center line of the iron core 41 of the electromagnet portion 40 is L1. In this case, the straight line L1 intersects the straight line L0 on the arrangement surface 51, and forms an angle θ in the direction away from the first contact mechanism 10 (in other words, clockwise) in the first direction X. With this configuration, the distance between the first contact mechanism 10 and the electromagnet portion 40 in the first direction X can be shortened, so that the size can be reduced in the first direction X in addition to the third direction Z. An electromagnetic relay 1 having two contact mechanisms can be realized.

As shown in FIG. 7, the configuration of the electromagnetic relay 1 of FIG. 5 and the configuration of the electromagnetic relay 1 of FIG. 6 may be combined. That is, while forming the end portion 331 of the third movable member 33 connected to the second movable member 32 in an L shape, the first contact mechanism 10 in the first direction X as the third movable member 33 moves away from the base 50 in the second direction Y. The electromagnet portion 40 may be tilted in a direction away from the other.

As shown in FIG. 8, the electromagnet portion 40 may have an L-shaped suction member 44 instead of the suction portion 43 of the iron core 41. The suction member 44 is provided at the end of the iron core 41 in the second direction Y, which is farther from the arrangement surface 51. The suction member 44 is composed of a first member 441 extending in a direction intersecting the iron core 41 and a second member 442 extending along the iron core 41. The second member 442 has a suction surface 443 facing the second movable member 32. With such a configuration, the number of turns of the coil of the electromagnet portion 40 can be increased, and the area of the suction surface 443 can be easily increased. As a result, the electromagnet portion 40 can be miniaturized, so that a miniaturable electromagnetic relay 1 having two contact mechanisms can be realized.
