があった。Conventionally, this type of polarized relay is disclosed in Japanese Utility Model Publication No. 47-42284, in which the electromagnetic part and the contact part are brought out to the outside by a plug-in terminal, so if a socket can be used, it can be easily recognized as a good product. Although it has the advantage of being replaceable, since the permanent magnet 12 is simply fixed at the approximate center of the fixed magnetic piece 15 without any positioning means, it is difficult to position the permanent magnet 12 with respect to the fixed magnetic piece 15, making it difficult to accurately magnetically position the permanent magnet 12. There was a problem in that it became difficult to obtain a stable polarized relay with bistable operation. Moreover, the general method of attaching the permanent magnet 12 to the fixed magnetic piece 15 is as follows.
Bonding by welding or adhesive is possible, but welding has a high magnetic resistance at the fused joint surface between the permanent magnet 12 and the fixed magnetic piece 15, and bonding has a high magnetic resistance between the two. Since the agent is interposed, the magnetic resistance may increase in this case as well, and in either case, the magnetic resistance of the magnetic path increases, resulting in a problem of poor magnetic efficiency.

定動作ができる有極リレーを提供するにある。The present invention has been made to address and improve the above-mentioned problems, and its purpose is to provide a polarized relay capable of stable bistable operation with good magnetic efficiency.

ア７は同一状態を保持している。Now, when current is applied to the coil 4 from one direction, the armature 7 swings, and one end 7a of the armature 7 comes into contact with one magnetic pole surface 1c of the yoke 1, and the other end 7a contacts the other magnetic pole surface of the yoke 1. At the same time, the movable contact 9 at one end of the movable contact spring 8 comes into contact with one fixed contact 11, and the movable contact 9 on the opposite side opens from the other fixed contact 11. Even if the coil 4 is de-energized, the armature 7 remains in the same state due to the magnetic flux generated from the permanent magnet 2 and passing through the closed magnetic path from one end 7a of the armature 7 to one magnetic pole 1b of the yoke 1 to the permanent magnet 2. .

Even if the current is stopped, the same state is maintained as described above. This is a so-called bistable polarized relay.
