By the way, in the conventional polarized relay of this type, when the coil is energized in the forward and reverse directions, the armature is attracted to one of the magnetic pole surfaces of the iron core, and the armature is applied to the coil. A so-called bistable operation in which the attracted state is maintained even when the power supply is stopped was generally performed. In order to perform monostable operation in which the armature returns so as to be attracted to a specific magnetic pole surface of the iron core when the energization of the coil is stopped using this bistable polarized relay, various methods have been conventionally used. Although proposed, in each case, there was a problem that a drastic structural change or a troublesome structural change was required.

The present invention has been made in view of the above problems, and an object thereof is to obtain a monostable operation type polarized relay relatively easily from a bistable operation type polarized relay. In particular, in the present invention, in the monostable type, when the coil is de-energized, the armature is oscillated toward the normally closed contact side to stabilize the supporting force of the armature in the normal state. Therefore, it is an object of the present invention to provide a polarized relay which can stabilize the contact operation of the normally closed contact and enhance the reliability of the relay.

Since the operation can be performed and the spring load characteristics of the hinge spring piece 6a of the contact spring 6 are only unbalanced on both sides of the swing fulcrum, for example, only by changing the shape of the hinge spring piece 6a, the other members can It is possible to relatively easily configure a monostable polarized relay from a bistable polarized relay without changing the above. Moreover, particularly in the present invention, when the armature 5 is oscillated by the spring urging force in the unbalanced spring load characteristic toward the fixed contact 9 on the normally closed side, the coil 3 is de-energized. The armature 5 is oscillated and urged toward the fixed contact 9 on the normally closed side, and the armature 5 is held by the spring biasing force for monostable in addition to the magnetic force of the permanent magnet 4, and the armature in a normal state It is intended to stabilize the bearing force of, to stabilize the contact operation of the normally closed contacts, and to improve the impact resistance and vibration resistance.

It becomes possible to operate, and it is possible to make it a monostable type by simply unbalancing the spring load characteristics of the hinge spring piece of the contact spring on both sides of the swing fulcrum. It is possible to relatively easily configure a monostable operation type polarized relay from a bistable operation type polarized relay without changing any other member by simply changing Moreover, particularly in the present invention, since the armature is oscillated and urged toward the normally closed fixed contact side by the spring urging force in the unbalanced spring load characteristic, the armature is normally urged when the coil is de-energized. By swinging the fixed contact on the closed side, the armature is held by the spring biasing force for monostable in addition to the magnetic force of the permanent magnet, and the supporting force of the armature in the normal state is stabilized. The advantages are that the contact operation of the normally closed contact can be stabilized, the shock resistance and the vibration resistance can be improved, and the reliability of the relay can be improved.
