等がある。<Prior art and its problems> Conventionally, as a protector using bimetal, for example, (1) Japanese Patent Publication No. 55-6971, No. 51-5704
The movable contact lever itself is made of bimetal material as shown in Japanese Patent Publication No. 51-18069, (2) Japanese Patent Publication No. 56-31694, Japanese Utility Model Publication No. 58-4
As shown in Publication No. 0505, a bimetal is attached to a movable contact lever in a parallel state.
As shown in '6512, there is one in which an inverted bimetal is interposed between a base for fixing a movable contact lever and a movable contact lever.
ところで、可動接触レバーをバイメタル材料で構成した
（１）のものにあっては、定常電流における動作温度と
過電流時の動作時間の設定は、無負荷電流時のバイメタ
ルの動作温度を適当に選定して実験により求めるのか普
通である。しかし、定常電流での動作温度と過電流時の
動作時間の両者を所望の値に設定することは、バイメタ
ル内を流れる電流のジュール発熱の影響で困難である。By the way, for (1) in which the movable contact lever is made of bimetal material, the operating temperature at steady current and operating time at overcurrent are set by appropriately selecting the operating temperature of the bimetal at no-load current. It is normal to find it by experiment. However, it is difficult to set both the operating temperature at steady current and the operating time at overcurrent to desired values due to the Joule heat generation of the current flowing in the bimetal.
また、可動接触レバーにバイメタルを付設する構造の（
２）のものでは、バイメタルが可動接触レバーと共にベ
ースにカシメられるので、カシメ時にバイメタルが初期
応力を受けることかある。In addition, a structure in which a bimetal is attached to the movable contact lever (
In the case of 2), since the bimetal is caulked to the base together with the movable contact lever, the bimetal may receive initial stress during caulking.
そして、この初期応力により温度設定が狂ってしまい、
検査工程で不良品となった製品の再生のためには、カシ
メ部を外してバイメタルを取り替えなければならないと
いう問題がある。This initial stress causes the temperature settings to go awry,
In order to recycle a product that is found to be defective in the inspection process, there is a problem in that the caulked portion must be removed and the bimetal must be replaced.

た（３）のものは、上記のような温度特性の変化やバイ
メタル取り替え上の問題はないものの、反転時の実効ス
トロークが小さい場合には、接点がチャタリングを起こ
して作動不良となる欠点がある。Roughly speaking, the type (3) that uses a reversing bimetal that is not caulked does not have the above-mentioned changes in temperature characteristics or problems in replacing the bimetal, but if the effective stroke at the time of reversing is small, The drawback is that the contacts may chatter, resulting in malfunction.
以上のように、これらはそれぞれ上記のような欠点があ
り満足できるものではない。As mentioned above, each of these has the above-mentioned drawbacks and is not satisfactory.
すなわち、バイメタルを任意の設定温度で正確に作動き
せるためには、バイメタルには直接電流を流さず、しか
も、過電流による発熱がバイメタルに直接伝わるように
することか好ましい。That is, in order to operate the bimetal accurately at an arbitrary set temperature, it is preferable not to allow current to flow directly through the bimetal, but to allow heat generated by overcurrent to be directly transmitted to the bimetal.
また、５アンペア以下の小電流で使用する場合には、バ
イメタルを作動させるための発熱を確保するために発熱
部の幅を特に狭くする必要があり、３アンペアの場合に
おいて発熱部は１ｍｍ以下の幅となるので、この部分の
補強を考慮する必要がある。In addition, when using a small current of 5 amperes or less, the width of the heating part must be particularly narrow to ensure the heat generation required to operate the bimetal, and in the case of 3 amperes, the heating part must be 1 mm or less. Since this is the width, it is necessary to consider reinforcing this part.

It is a contact lever. 3 is the distal end of the fixed contact lever 2 (this is the fixed contact provided); 4 is the movable contact 5
It is a movable contact lever with a movable contact lever disposed at its tip, and the movable contact 5 can be opened and closed with respect to the fixed contact 3. Reference numeral 6 designates an inverted bimetal that is in movable contact and is disposed below the bar 4.

すようにジグザグ状に形成することもある。As shown in FIGS. 2 and 4, the movable contact lever 4 may be entirely made of a spring material with relatively high electrical resistance, and a portion may be made thinner to form the heat generating portion 7. In this case, the central part of the movable contact lever 4 may be made to protrude toward the base 1 side to form the heat generating part 7, and the heat generating part 7 may be made to easily come into contact with the inverted bimetal 6. Since this is for adjusting the heat generation amount or setting the heat generation amount to an arbitrary value, the heat generation portion 7 does not necessarily have to be narrower than the others. Further, as shown in FIGS. 4 and 5, only the heat generating portion 7 may be made of a spring material having relatively high electrical resistance. As a spring material having a relatively high electrical resistance, for example, stainless steel, spring steel, iron chrome, nickel chrome, etc. can be used. The reason why a material with relatively high electrical resistance is used is to ensure that the heat generating portion 7 generates heat quickly. Furthermore, as shown in FIG. 7, the heat generating portion 7 of the movable contact lever 4 may be partially formed into a thin part and formed into a zigzag shape as shown in the same figure.

る。The inverted bimetal 6 has a shallow dish shape slightly curved in the vertical direction. Then, as shown in FIGS. 1 and 3, the high expansion coefficient side is placed on the upper surface of the base 1 with the high expansion coefficient side in contact with the heat generating part 7 of the movable contact lever 4, or as shown in FIGS. 9 and 1.
As shown in FIG. 0, it is disposed on the upper surface of the base 1 so that the low expansion coefficient side is in movable contact and abuts against the heat generating part 7 of the bar 4.

In order to attach the reinforcing member 8 to the movable contact lever 4, a part of the movable contact bar 4 may be bent and fixed. Further, the reinforcing member 8 is made of an insulating material.

転バイメタル６と発熱部７の接触かよりいっそう確実な
ものとなる。As shown in FIG. 9, when the low expansion coefficient side of the inverted bimetal 6 is placed on the upper surface of the base so that it is in contact with the heat generating part 7 of the movable contact lever 4, that is, when it is placed at normal time, it is placed on the warped surface or on the When disposed on the base so as to face the movable contact lever 4, it is possible to prevent rattling of the inverted bimetal 6 and to ensure that the heat generating part 7 of the movable contact lever 4 is in contact with the inverted bimetal 6. As a result, there is an effect that electric heating can be reliably performed during overcurrent heat generation. Further, as shown in FIG. 10, if the fixed contact lever 2 is made of an elastic material, the contact between the inverted bimetal 6 and the heat generating part 7 becomes even more reliable.
〈作 用〉
しかして、可動接触レバー４に電流が流れると、反転バ
イメタル６は発熱部７と接触しでいるので、発熱部７の
発熱により反転バイメタル６は加熱されることになる。<Function> When current flows through the movable contact lever 4, the inverted bimetal 6 is in contact with the heat generating part 7, so the inverted bimetal 6 is heated by the heat generated by the heat generating part 7.
しかし、平常状態では、反転バイメタル６は加熱されで
もバイメタルの作動温度以下であるので、バイメタルは
作動しない。However, under normal conditions, even if the inverted bimetal 6 is heated, the temperature is below the operating temperature of the bimetal, so the bimetal does not operate.
過電流が回路に流れた場合には、可動接触レバー４にも
過電流か流れることになり、発熱部７の発熱も大きくな
る。そして反転バイメタル６が作動温度以上に加熱され
ると反転バイメタル６が作動して、可動接点５を固定接
点３から離し、電路を開放する。If an overcurrent flows through the circuit, the overcurrent will also flow through the movable contact lever 4, and the heat generated by the heat generating portion 7 will also increase. When the inverted bimetal 6 is heated to a temperature higher than the operating temperature, the inverted bimetal 6 is activated, separating the movable contact 5 from the fixed contact 3 and opening the electric circuit.
反転バイメタル６自体には電流か流れないので、バイメ
タルの作動温度と過電流による発熱温度を任意に選択す

熱部７の幅を狭くてきるので弱電流に対しても使用でき
る。Since no current flows through the inverted bimetal 6 itself, it is possible to arbitrarily select the operating temperature of the bimetal and the temperature at which heat is generated due to overcurrent. Further, if the reinforcing member 8 is used, the width of the heat generating portion 7 can be narrowed, so that it can be used even for weak currents.
