の上面に対向する可動鉄片８を備えている。 FIG. 1 shows a magnetic relay according to the present invention.
An input coil 3 and an output coil 4 are wound around one protruding end 2a and the other protruding end 2b of the iron core 2 so as to generate magnetic fields in the same direction, respectively.
A contact board 5 is fitted onto and fixed to the upper part of each of the protruding ends 2a, 2b, and is held by a support piece 6 protruding from the contact board 5. One end is supported by a spring hinge piece 7 provided on the edge, and the other side protruding end 2b
It is equipped with a movable iron piece 8 facing the upper surface of.
そして上記可動鉄片８の揺動端下部にはバネ性

になつている。 Further, a fixed contact 10 is provided on the substrate 5 at the lower part of the contact 9a of the contact piece 9, and this fixed contact 10 is connected to one end of the output coil 4, and further connected to the other end of the coil 4. The cord connected to the contact piece 9 is connected as output terminal portions 11 and 12 to equipment constituting an output circuit (not shown).

電回路を構成するようにしている。 Furthermore, as shown in FIG. 2, a capacitor 15 is connected in series between the input terminal portions 13 and 14 of the input coil 3, and the input terminal 13,
A resistor 16 for discharging is connected in parallel between the coils 14 and a resistor 17 for suppressing rush current is connected in series, and these constitute a charging/discharging circuit including the coil 3. .

コイル４には出力回路からの電流が投入され、上
記磁界と同方向の磁束φOが発生する。 Therefore, when an input signal is applied between the input terminals 13 and 14 of the magnetic relay MR configured as described above, as shown in FIGS. A large charging current flows and the capacitor 15 is charged, but this current
Due to the IS, a loop-shaped magnetic flux φ S in the direction shown in FIG. 4 is generated in the magnetic circuit constituted by the iron core 2 and the movable iron piece 8, and this magnetic flux φ S causes the movable iron piece 8 to connect to the hinge piece 7 and the movable contact. The contact point 9 is brought into suction contact with the other protruding end 2b of the iron core 2 against the spring pressure of the contact point 9.
Close between a and 10. At the same time, a current from the output circuit is applied to the output side coil 4, and a magnetic flux φ O in the same direction as the above magnetic field is generated.
また上記充電電流ISは時間とともに減衰し、ほ
ぼゼロに収束されるが上述の如く出力回路側から
得た磁束φOによつて磁化状態が保たれ、可動鉄
片８は動作状態を維持する。 Further, the charging current I S attenuates with time and converges to almost zero, but as described above, the magnetized state is maintained by the magnetic flux φ O obtained from the output circuit side, and the movable iron piece 8 maintains its operating state.
次いで入力端子１３，１４間を開路すると、コ
ンデンサ１５に滞つた電荷は放電し、大きな放電
電流IRが放電用抵抗１６を介して流れる。 Next, when the input terminals 13 and 14 are opened, the charge accumulated in the capacitor 15 is discharged, and a large discharge current I R flows through the discharge resistor 16.
この電流IRは上記充電電流ISと逆方向であるた

一時的に生じ、磁束φOを打消し、上記ヒンジ片
７及び可動接触片９のバネ圧により上記可動鉄片
８を第１図に示す元位置に復帰させ、出力側接点
９ａ，１０間を開路し、コイル４への電流を遮断
する。 Since this current I R is in the opposite direction to the charging current I S , a magnetic flux φ R in the opposite direction is temporarily generated in the magnetic circuit, canceling the magnetic flux φ O , and causing the hinge piece 7 and the movable contact The movable iron piece 8 is returned to the original position shown in FIG. 1 by the spring pressure of the piece 9, the output side contacts 9a and 10 are opened, and the current to the coil 4 is cut off.

る。 Therefore, the above operation allows the output side circuit to be opened and closed as desired by turning on and off the input side switch. Note that even if the power supplied from the input terminals 13 and 14 is small, a large charge or
Since the discharge current is applied to both ends of the input coil 3,
The number of turns of the coil 3 can be made extremely small, and the amount of heat consumed from the coil is extremely small compared to a conventional coil with a large number of turns.
次に第６図及び第７図は以上の如く構成された
この発明に係るマグネツトリレーMRの入力側及
び出力回路側を夫々別電源とし、該リレーMRを
停電記憶リレーとして用いた場合の適用例を示す
ものである。 Next, FIGS. 6 and 7 show an application in which the input side and output circuit side of the magnetic relay MR according to the present invention configured as described above are respectively provided with separate power supplies, and the relay MR is used as a power failure memory relay. This is an example.
上記リレーMRの入力端子１３，１４間は蓄電

２１を直列に接続した回路が形成され、また出力
端子部１１，１２間には商用交流電源２２を整流
回路２３で整流し、その直流回路に負荷（出力機
器）２４を直列に接続してある。 A circuit is formed between the input terminals 13 and 14 of the relay MR, in which a storage battery 20 is used as a power source and an input switch 21 for opening and closing the input switch 21 is connected in series, and a commercial AC power supply 22 is connected between the output terminals 11 and 12. It is rectified by a circuit 23, and a load (output device) 24 is connected in series to the DC circuit.
上記回路構成において、入力スイツチ２１を開
閉することにより上述の作用により出力端子部１
１，１２間が開閉され、これに伴い負荷２４が
ON、OFF動作する。 In the above circuit configuration, by opening and closing the input switch 21, the output terminal section 1
1 and 12 are opened and closed, and accordingly the load 24 is
ON, OFF works.
また上記入力スイツチ２１が入れたままの状態
で負荷２４側が何らかの原因で停電状態となつた
場合には磁束φOは消磁され、また入力側の磁束
φSもゼロとなつているため可動鉄片８は復帰し、
出力端子１１，１２間を開路する。 In addition, if the input switch 21 is left on and the load 24 side is in a power outage state for some reason, the magnetic flux φ O is demagnetized and the magnetic flux φ S on the input side is also zero, so the movable iron piece 8 returned,
The circuit between the output terminals 11 and 12 is opened.
そして、所定時間経過により停電が復旧し、か
つ上記入力スイツチ２１が入れつぱなしの状態に
おいては磁束φSは依然としてゼロに保たれ、これ
によりスイツチ２１が入つたままでも出力端子１
１，１２間は開路された状態にある。 Then, when the power outage is restored after a predetermined period of time has passed and the input switch 21 remains on, the magnetic flux φ S remains at zero, so even if the switch 21 remains on, the output terminal 1
1 and 12 are in an open state.
また上記リレーMRを再度働かせるには一たん
スイツチ２１を切れば、鉄心２に磁界φRが発生
するが、この方向は可動鉄片８の吸引方向とは逆
向きであるため、リレーMRの作動入力とはなら
ない。 In addition, in order to activate the relay MR again, once the switch 21 is turned off, a magnetic field φ R is generated in the iron core 2, but since this direction is opposite to the suction direction of the movable iron piece 8, the activation input of the relay MR is It is not.
次いでスイツチ２１を再投入すれば前述の如き
作用により再び出力端子部１１，１２間を閉成す
るのである。 Then, when the switch 21 is turned on again, the connection between the output terminals 11 and 12 is again closed by the action described above.
よつて、上記の如く構成した場合には停電時等
において、これが復旧した時点での入力スイツチ
の切忘れによる機器の再起動及びこれに伴う誤作
動や事故等を未然に防止できる。 Therefore, when configured as described above, in the event of a power outage, etc., it is possible to prevent restarting of the equipment due to forgetting to turn off the input switch when the power is restored, and malfunctions and accidents associated with this can be prevented.
なお、入出力側を同一電源から取つた場合にあ
つても機器内部の遮断等により、回路をOFF状
態に保たなければならない場合等にも適合できる
ことは勿論である。 It goes without saying that even if the input and output sides are connected to the same power source, the circuit must be kept in an OFF state due to an internal cutoff, etc. of the device.
