示すように組み込まれる。A circuit breaker may be equipped with accessory devices such as an auxiliary switch that operates according to whether the main unit is turned on or off, an alarm switch that alerts you to a circuit abnormality, or a voltage trip device that trips the main unit from a distance. are installed as shown in FIGS. 1 and 2 according to the user's needs after the main body is completed.
第１図、第２図において回路しゃ断器に組み込まれた付
属装置１のコード２はケース３とカバー４との合わせ目
５に設けられた切欠き６からケース３の外部に引き出さ
れている。In FIGS. 1 and 2, the cord 2 of the accessory device 1 incorporated in the circuit breaker is drawn out from the case 3 through a notch 6 provided at a joint 5 between the case 3 and the cover 4.
従来、この切欠きの形成はケースまたはカバーのいずれ
かに追加して加工する方法によっていたが、ケース側に
切欠きを設けるとそのための切削くずが内部に入り込み
、接点の接触不良などの故障が起こり易い。Conventionally, this notch was formed by adding it to either the case or the cover and machining it, but if the notch was provided on the case side, cutting waste would get inside, causing malfunctions such as poor contact of the contacts. It's easy to happen.
また、カバー側に切欠きを設けると、カバーを取付ける
際既に配線されているコードをカバー側の切欠きの中へ
通すために作業時。Also, if you make a notch on the cover side, you can pass the already wired cord through the notch on the cover side when installing the cover.
間が長くなる。The interval becomes longer.
また、ケース、カバーのいずれの側に切欠きを設ける場
合も、誤ってコードを切欠きからずらしてケースとカバ

ある。As shown in FIG. 4, the outlet 14 of the cord 2 connected to the coil 9 is provided with a notch 6 at the upper edge of the side wall of the case 3, and both sides 6a of the notch 6 are sharpened. 15a and a thick part 15c forming an outer edge 15b that fits into both sides 6a of the notch of the case. An elastic lid 15 made of, for example, molded material or rubber is placed so that the thin part 15a is on the outside of the case 3. It is embedded in.
即ち第４図においては右側がケースの内側、左側がケー
スの外側となる。That is, in FIG. 4, the right side is the inside of the case, and the left side is the outside of the case.
前記の切欠きゃ蓋の形状は半円形や半楕円形でもよい。The shape of the cutout lid may be semicircular or semielliptical.
また切欠きの側面と蓋１５の外線とを上述したのとは逆
に形成しでもよい。Furthermore, the side surfaces of the notch and the outer line of the lid 15 may be formed in a manner opposite to that described above.
このコード引き出し口１４はコード２を引き出さない回
路しゃ断器では蓋１５によってケース内外をしゃ断して
いる。In a circuit breaker in which the cord 2 is not pulled out, the cord outlet 14 is used to shut off the inside and outside of the case with a lid 15.
このコード引き出し口１４からコード２を引き出すには
、電圧引き外し装置１を回路しゃ断器ケース内部に装着

し当て、カバー４をかぶせれば、コード２を弾性のある
蓋１５の薄い部分１５ａを押しのけて切欠き６に食い込
み、コード２を挾み込むことができる。To pull out the cord 2 from the cord outlet 14, after installing the voltage trip device 1 inside the circuit breaker case, press the cord 2 against the upper edge of the lid 15 of the outlet 14, and cover with the cover 4. , the cord 2 can be pushed away from the thin part 15a of the elastic lid 15 and bit into the notch 6, so that the cord 2 can be inserted.
この時、蓋１５の薄い部分１５ａはコード２を包むよう
な状態になり、切欠き６に間隙は出来ない。At this time, the thin portion 15a of the lid 15 wraps around the cord 2, leaving no gap in the notch 6.
以上述べたように本考案による回路しゃ断器の付属装置
のコード引き出し口はケースの成形時設けた切欠きに１
個の底形した弾性材製蓋を嵌め込むだけであるから工作
および蓋の装置が簡単であり、安価である。As mentioned above, the cord outlet of the accessory device of the circuit breaker according to the present invention is located in the notch provided during molding of the case.
Since the lid made of elastic material with a bottom shape is simply fitted, the construction and lid equipment are simple and inexpensive.
また、コードを引き出さない場合は蓋によりケース内外
をしゃ断しているから湿気や塵埃などの浸入するおそれ
もない。Furthermore, when the cord is not pulled out, the lid shuts off the inside and outside of the case, so there is no risk of moisture or dust entering.
コードを引き出す場合はコードを上から押し込みカバー
をかぶせるだけであるから作業は簡単である。When pulling out the cord, the work is easy as all you have to do is push the cord in from above and cover it with a cover.
しかもコード引き出し口の蓋はコードを包み込み、ケー
ス内外に通ずる間隙ができないから湿気や塵埃などの浸
入するおそれもないという効果もある。Moreover, the cord drawer cover wraps around the cord, leaving no gap between the inside and outside of the case, so there is no risk of moisture or dust entering.
さらに、切削くずｌこよる問題も生じない。Furthermore, the problem of excessive cutting waste does not occur.
