That is, the operation state shown in FIG. 2 (that is, the first end 751 of the second iron piece 75 of the first rotation block 70 and the first end 851 of the second iron piece 85 of the second rotation block 80 are the first The second end 742 of the first iron piece 74 of the first rotating block 70 and the second end 842 of the first iron piece 84 of the second rotating block 80 are in contact with the suction portion 622 of the yoke 62, and the second yoke. 63, the first movable contact portion 32 and the first fixed contact portion 21 are in contact with each other, and the second movable contact portion 52 and the second fixed contact portion 41 are in contact with each other. A current in a predetermined direction (for example, direction A in FIG. 2) is supplied to one electromagnet unit 60, and the first rotation block 70 and the second rotation block 80 are changed to the first rotation block 70 and the second rotation block. Rotate clockwise as viewed from the extending direction of the 80 rotation shafts 71 and 81 Make. Then, along with the rotation of the first rotation block 70 and the second rotation block 80, the arm portions 721 and 821 also rotate clockwise, and the first movable member 90 moves toward the fourth side wall 114 of the base 11. The first movable contact 32 is moved away from the first fixed contact 21 and the second movable member 100 is moved toward the third side wall 113 of the base 11 to move the second movable contact 52. The second fixed contact portion 41 is separated. Thereby, the electromagnetic relay 1 is returned from the operating state (that is, the first end 741 of the first iron piece 74 of the first rotation block 70 and the first end of the first iron piece 84 of the second rotation block 80). 841 contacts the suction portion 622 of the first yoke 62, and the second end 752 of the second iron piece 75 of the first rotation block 70 and the second end 852 of the second iron piece 85 of the second rotation block 80. However, the first movable contact portion 32 is separated from the first fixed contact portion 21 and the second movable contact portion 52 is separated from the second fixed contact portion 41 in contact with the suction portion 632 of the second yoke 63. State).

  In the electromagnetic relay 1 in the operating state, the first movable contact piece 31 is disposed on one side (for example, the left side in FIG. 2) in the extending direction of the first movable contact piece 31 that intersects the contact / separation direction. The first fixed contact side terminal 20 or the first movable contact side terminal 30 (here, the first fixed contact side terminal 20) is a terminal to which current is supplied. Further, the second fixed contact side terminal 40 or the second movable contact disposed on the other side (for example, the right side in FIG. 2) of the first movable contact piece 31 in the extending direction with respect to the second movable contact piece 51. The side terminal 50 (here, the second fixed contact side terminal 40) is a terminal to which current is supplied. That is, in the electromagnetic relay 1, during energization, the current flowing through the conduction path constituted by the first fixed contact side terminal 20, the first movable contact side terminal 30, and the first movable contact piece 31, and the second fixed contact The currents flowing through the conduction path formed by the contact side terminal 40, the second movable contact side terminal 50, and the second movable contact piece 51 flow in opposite directions.

  Further, a current in a direction different from a predetermined direction (for example, the B direction in FIG. 2) is supplied to the electromagnet portion 60 of the electromagnetic relay 1 in the restored state, so that the first rotating block 70 and the second rotating block 80 are The first rotation block 70 and the second rotation block 80 are rotated counterclockwise when viewed from the extending direction of the rotation shafts 71 and 81. Then, with the rotation of the first rotation block 70 and the second rotation block 80, the arm portions 721 and 821 also rotate counterclockwise, and the first movable member 90 moves toward the third side wall 113 of the base 11.

Rotating blocks (that is, the first rotating block 70 and the second rotating block 80), and by rotating each rotating block, each movable contact portion is brought into contact with or separated from the corresponding fixed contact portion. ing. For this reason, compared with the electromagnetic relay provided with only one rotation block, since the number of movable contact parts to be contacted / separated by one rotation block can be reduced, the electromagnetic relay 1 that is easy to design can be realized. .

  Further, by applying the electromagnetic relay 1 to a smart meter, a smart meter that is easy to design and easily obtains the required performance can be realized.

  Further, the rotation shaft 71 of the first rotation block 70 and the rotation shaft 81 of the second rotation block 80 are arranged on the same axis. For this reason, the accommodating part 13 can be space-saving in the direction which cross | intersects each rotating shaft 71,81.

  The polarity of the permanent magnet 73 of the first rotation block 70 and the polarity of the permanent magnet 83 of the second rotation block 80 are not limited to the same case, and may be different from each other. In this case, for example, as shown in FIG. 5, in the operating state, the first end 741 of the first iron piece 74 of the first turning block 70 and the first end of the second iron piece 85 of the second turning block 80. 851 contacts the suction portion 622 of the first yoke 62, and the second end 752 of the second iron piece 75 of the first rotation block 70 and the second end 842 of the first iron piece 84 of the second rotation block 80.

To touch.

  Thus, since the polarity of the permanent magnet 73 of the first rotation block 70 and the polarity of the second rotation block 80 permanent magnet 83 are different from each other, it is assumed that a strong magnetic field (that is, an external magnetic field) is applied from the outside. ) And the first turning block 70 is forcibly turned, so that the on / off state of the first fixed contact portion 21 and the first movable contact portion 32 is forcibly changed. The second rotation block 80 is not forcibly rotated by an external magnetic field. That is, even when an external magnetic field is applied to the electromagnetic relay 1, either the first movable contact portion 32 or the second movable contact portion 52 is always opened from the first fixed contact portion 21 or the second fixed contact portion 41. Can be separated. For this reason, for example, when the electromagnetic relay 1 is applied to a smart meter, it is possible to prevent theft due to an unauthorized operation using a powerful magnet.

The first movable block 70 can be rotated in the range in which the first movable block 70 can be rotated. The range in which the second rotation block 80 can be rotated when contacting or separating 41 may be different from each other.

Good.

  Further, the opposed area of the first iron piece 74 of the first rotating block 70 facing the suction portion 622 of the first yoke 62 or the suction portion 632 of the second yoke 63 (that is, the end portions 741 and 742 of the first iron piece 74). Of the first yoke 62 or the suction portion of the second yoke 63 in the first iron piece 84 of the second rotating block 80. The facing area facing 632 (that is, the area of the portion where the end portions 841 and 842 of the first iron piece 84 and the adsorbing portions 622 and 632 of the yokes 62 and 63 are in contact) may be different from each other. .

  Similarly, in the second iron piece 75 of the first rotation block 70, the opposing area facing the suction portion 622 of the first yoke 62 or the suction portion 632 of the second yoke 63 (that is, each end portion 751 of the second iron piece 75, 752 and the area of the portion where the suction portions 622 and 632 of the yokes 62 and 63 are in contact) and the suction portion 622 of the first yoke 62 or the suction of the second yoke 63 in the second iron piece 85 of the second rotating block 80. Even if the facing area facing the portion 632 (that is, the area of the portion where the end portions 851 and 852 of the second iron piece 85 contact the suction portions 622 and 632 of the yokes 62 and 63) is different from each other. Good.

  For example, in FIG. 7, wide portions 753 and 853 are provided on the first end 751 of the second iron piece 75 of the first turning block 70 and the first end 851 of the second iron piece 85 of the second turning block 80, respectively. Wide portions 743 and 843 are provided on the second end 742 of the first iron piece 74 of the first turning block 70 and the second end 842 of the first iron piece 84 of the second turning block 80, respectively.

By configuring in this way, the iron pieces 74, 75 of the first rotating block 70 and the second rotating block 80 that are attracted to the yokes 62, 63 when the electromagnetic relay 1 changes from the return state to the operating state. The opposing area of 84 and 85 can be reduced.

  In FIG. 9, the length of the first end 751 of the second iron piece 75 of the first rotation block 70 is made longer than the length of the second end 752, and the second iron piece 85 of the second rotation block 80. The first end 851 is made longer than the second end 852, and the second end 742 of the first iron piece 74 of the first rotation block 70 is made longer than the first end 741. The length of the second end 842 of the first iron piece 84 of the second rotating block 80 is longer than the length of the first end 841. By configuring in this way, the iron pieces 74, 75 of the first rotating block 70 and the second rotating block 80 that are attracted to the yokes 62, 63 when the electromagnetic relay 1 changes from the return state to the operating state. The opposing area of 84 and 85 can be increased. In this case, as shown in FIG. 10, only the lengths of the first ends 751 and 851 of the second iron piece 75 of the first turning block 70 and the second iron piece 85 of the second turning block 80 are set to the second length. It can be longer than the ends 752 and 852.

  As described above, the facing area of the first iron piece 74 of the first rotating block 70 facing the suction portion 622 of the first yoke 62 or the suction portion 632 of the second yoke 63 is the first iron piece of the second rotating block 80. 84 is configured to be different from the facing area facing the suction portion 622 of the first yoke 62 or the suction portion 632 of the second yoke 63 (or the first yoke of the second iron piece 75 of the first rotating block 70).

With this configuration, for example, the first fixed contact portion 21 and the first movable contact portion 32 of the first rotation block 70, and the second fixed contact portion 41 and the second movable contact portion of the second rotation block 80 are used. Fixed contact that shifts the timing of contact or separation with the part 52, or uses the fixed contact portion and the movable contact portion that are contacted and separated by one rotating block as the main contact portion, and is contacted and separated by the rotation of the other rotating block Or a movable contact portion as an auxiliary contact portion.

  Further, the rotation shaft 71 of the first rotation block 70 and the rotation shaft 81 of the second rotation block 80 are not limited to being arranged on the same axis. For example, as shown in FIGS. 11 and 12, the first rotation block 70 and the second rotation block 80 may be arranged at intervals along the outer surface of the coil 61 of the electromagnet unit 60. As shown in FIG. 14, the first rotation block 70 and the second rotation block 80 may be arranged symmetrically with respect to the winding center axis CL of the electromagnet unit 60.
