【発明の詳細な説明】 この発明はリレー(電磁継電器)に関する。[Detailed description of the invention] The present invention relates to a relay (electromagnetic relay).

じめこの消耗に備えて接点を大きなものとし、長寿命化
を図ってい友。In a conventional relay, when the energizing current is cut off, the contacts open, so the load current flowing through the contacts is cut off in a random phase. Therefore, it is possible that the AC load may be cut off in one phase when the instantaneous value of the current is at its peak. Line dot material tube wear out. Conventionally, in preparation for this wear and tear, the contacts were made larger to extend their lifespan.

。The present inventor has devised a simple configuration in which the contacts separate near the load-current phase, thereby reducing the number of consumable contacts, extending the life of even small contacts, and saving precious metals such as gold, silver, etc. It is assumed that we will provide a relay tube that can be used.

接触可能に対向して1&シ付けられている。Hereinafter, one embodiment of the present invention will be explained with reference to Figure #J. In Figures 1 and 2, terminals 1.
1 is provided on the insulating pace 8. this pace 8
A U-shaped iron core 8 around which a coil 2 is wound is fixed to the coil 20, and both ends of the coil 20 are connected to coil terminals 1.1. Furthermore, an elastic conductive gold J14D movable piece 6 is implanted in this pace 8.
The movable iron piece 4 is fixed to the fixed iron core 81M and is swingably supported. This movable iron piece 4 and fixed iron core 8
A fixed piece 7 made of conductive metal is implanted in the base 8 at a position surrounded by the edges. Contact points 5.5 are attached near the tips of the movable piece 6 and the fixed piece 7, respectively, so that the two sides face each other so that they can come into contact with each other.

The load 11 and the father power supply 12 are connected in series. Here, the switch 10t is closed by the fixed iron core 8 by the coil 2.

した磁束φCが*1+る。When the movable iron piece 4 is attracted to the fixed iron core 8, a magnetic closed circuit is formed as shown in FIG. 8, and a magnetic flux φ by the coil 2 flows through this closed circuit. Furthermore, since the load current IO flow path a'tx passes within this magnetic closed circuit, the magnetic flux φC generated by the load current ■ flows through this magnetic closed circuit by *1+.

遮断される。Now, suppose that the switch 10 is fully opened and the attraction force by the coil 2 is set to t-sero. Then, depending on the phase of the load current when it becomes zero, the instantaneous value of the load current IO is large to some extent, and the attractive force f due to the load mai is larger than the return force Fr due to the elasticity of the movable piece 6. , the movable iron piece 4 remains attracted and the contact 6.5 also remains closed. As a little time passes and the phase advances, it reaches a phase where it becomes negative rkfrkfi I, and as it approaches this phase, Fr >
f, the movable iron piece 4 separates from the fixed iron core 8, and the contacts 5, 5
Translated〈. That is, the load ThfiI is cut off at a phase near zero.

る必要がなく構成をm単にすることができる。As described above with respect to the embodiments, according to the present invention, the contacts can be opened in the phase when the load current is near zero, so the wear of the contacts is reduced and contact materials can be saved. Even small contacts can have a long life. In addition, the magnetic flux generated by the load current I/C is passed through the magnetic circuit where the fixed iron core around which the coil is wound and the movable iron piece are defeated. There is no need to provide a normal magnetic circuit and a breakthrough magnetic circuit, and the configuration can be simplified.
