35.35°から固定接点37.37’に切り換わる。The operation of the electromagnetic relay constructed as described above is similar to conventional relays of this type. That is, when the coil 16 is not energized, the card 20 rotates in the direction of arrow I), and the iron piece 28b or the upright piece 19 of the yoke 7 is rotated by the magnetic force of a permanent magnet (not shown).
The movable contact 33°33 is in contact with the fixed contact 35.35
' is closed. On the other hand, when the coil I6 is energized, the iron piece 28a is attached to the tip magnetic pole surface part (shielding plate LZa side) of the iron core [1].
is repelled and the iron piece 28b is attracted toward the magnetic shielding plate 12b, and the card 20 rotates in the opposite direction to the arrow P about the support shaft 4 as a fulcrum. This switches from the movable contact 33.33 or the fixed contact 35.35° to the fixed contact 37.37'.

、共通端子31は第3図。39 and the same) are punched out from a single hoop material and inserted into a mold. In this case, the mold is opened in three directions indicated by arrows Q, Q', and R in FIG. Therefore, the mold 55 (see FIG. 6), which opens upward (in the direction of arrow R), can be opened and closed, and the common terminal 31 as shown in FIG. 3 is used to cut the edges during resin molding.
第5図に示す形状とされている。It has the shape shown in FIG.
即ち、共通端子31の上部には第1の突起31aと中段
部には第2の突起31bとが突き出し加工にて形成され
ており、第2の突起31bは第1の突起と同一方向に突
出し、同一高さであると共に、若干幅広となっている。That is, a first protrusion 31a is formed on the upper part of the common terminal 31, and a second protrusion 31b is formed on the middle part by extrusion processing, and the second protrusion 31b protrudes in the same direction as the first protrusion. , are the same height and slightly wider.

形時において上部と下部とが同一平面上に位置している
ため、共通端子31のインサート時の搬送や位置決めが
極めて容易である。During insert molding, the common terminal 31 is inserted into the surface of the base l at a position indicated by a dashed line A. In other words, the second protrusion 31b is approximately half embedded in the base. In this way, by forming the second protrusion 31b directly below the first protrusion 31a, the first protrusion 31
It becomes possible to open and close the mold 55 and perform crisp cutting regardless of the presence of a (see FIG. 6). Moreover, since the upper and lower parts of the common terminal 31 are located on the same plane during insert molding, it is extremely easy to transport and position the common terminal 31 when inserting it.
