Description

本発明は電磁接触器に関し、特に、電磁接触器の消弧カバーの構造に適用して好適なものである。   The present invention relates to an electromagnetic contactor, and is particularly suitable for application to an arc extinguishing cover structure of an electromagnetic contactor.

電磁接触器は、電磁石の吸引力により接点を開閉できるもので、モータなどの負荷の自動開閉用として使用される。ここで、電磁接触器には、フレームに相対するように固定された一対の固定接触子と、これらの固定接触子の間を橋絡する可動接触子とからなる開閉部が各相に設けられ、この開閉部は消弧を促す消弧カバーで覆われている（特許文献１）。   An electromagnetic contactor can open and close a contact by the attractive force of an electromagnet, and is used for automatic opening and closing of a load such as a motor. Here, the electromagnetic contactor is provided with an opening / closing portion for each phase, which includes a pair of fixed contacts fixed to face the frame and a movable contact that bridges between the fixed contacts. The opening / closing portion is covered with an arc extinguishing cover that promotes arc extinction (Patent Document 1).

FIG. 12 is a perspective view showing the configuration of the conventional arc extinguishing cover as seen from the back side, and FIG. 13 shows a state in which the arc extinguishing cover is attached to the upper frame of the conventional electromagnetic contactor. FIG. 14 is a rear view showing a schematic configuration of the electromagnetic contactor of FIG. 13, and FIG. 15 is an enlarged cross-sectional view showing a joint portion of the electromagnetic contactor of FIG. 13.

図８から図１５において、電磁接触器には、絶縁体のフレームとして上部フレーム１と下部フレーム１１とが設けられている。そして、上部フレーム１には各相一対の固定接触子が相対するように固定され、下部フレーム１１に収容された操作電磁石の可動鉄心には、各相の固定接触子の間を橋絡する可動接触子が支持されている。
そして、これらの固定接触子と可動接触子とからなる各相の開閉部は、上部フレーム１の隔壁１１ａにより相間が隔てられ、消弧カバー２にて各相一体に覆われている。また、各相の相対する固定接触子の端部には、電源側及び負荷側の端子がそれぞれ一体形成され、これらの端子は相間に跨る端子カバー３にて覆われている。 8 to 15, the magnetic contactor is provided with an upper frame 1 and a lower frame 11 as insulator frames. A pair of fixed contacts of each phase is fixed to the upper frame 1 so as to face each other, and a movable iron core of the operation electromagnet accommodated in the lower frame 11 is movable to bridge between the fixed contacts of each phase. A contact is supported.
The open / close portions of the respective phases composed of the fixed contact and the movable contact are separated from each other by the partition wall 11a of the upper frame 1 and covered with the arc extinguishing cover 2 integrally with each phase. Further, terminals on the power supply side and the load side are integrally formed at the ends of the stationary contact elements facing each phase, and these terminals are covered with a terminal cover 3 straddling between the phases.

ここで、消弧カバー２には、四隅にそれぞれ配置された篏合フック２ａが設けられるとともに、上部フレーム１には、篏合フック２ａにそれぞれ相対するように配置された篏合フック１ａが設けられている。そして、消弧カバー２の篏合フック２ａを上部フレーム１の篏合フック１ａに篏合させることにより、消弧カバー２を上部フレーム１に装着することができる。   Here, the arc extinguishing cover 2 is provided with coupling hooks 2a arranged at the four corners, and the upper frame 1 is provided with coupling hooks 1a arranged so as to be opposed to the coupling hooks 2a. It has been. The arc-extinguishing cover 2 can be attached to the upper frame 1 by mating the mating hook 2 a of the arc-extinguishing cover 2 with the mating hook 1 a of the upper frame 1.

そして、消弧カバー２の脱着が容易に行えるようにするために、図１５に示すように、篏合フック２ａの篏合面１２ａには傾斜が設けられるとともに、電磁接触器の開閉動作による摩擦を低減するために、篏合フック２ａが篏合フック１ａに押し当てられるように寸法関係が設定されていた。
ここで、開閉動作による接点の消耗レベルを保守点検時に目視で確認できるよう消弧カバー２は取り外せる必要がある一方、短絡事故などで異常な高電流が流れた時に生じる高圧のアークエネルギーにより消弧カバー２が吹き飛び、接点などの充電部が露出するのを防止しなければならない。 And in order to make it easy to attach and detach the arc extinguishing cover 2, as shown in FIG. 15, the mating surface 12a of the mating hook 2a is provided with an inclination, and the friction caused by the opening / closing operation of the electromagnetic contactor. In order to reduce the dimensional relationship, the dimensional relationship is set so that the mating hook 2a is pressed against the mating hook 1a.
Here, the arc extinguishing cover 2 needs to be removed so that the contact wear level due to the opening / closing operation can be visually confirmed during maintenance inspection, while the arc extinguishing is caused by high-pressure arc energy generated when an abnormally high current flows due to a short circuit accident or the like. It must be prevented that the cover 2 is blown away and the charging part such as the contact point is exposed.

このため、特許文献１に開示された方法では、図１０に示すように、消弧カバー２の嵌め込み方向と直交する方向に端子カバー３を嵌め込み、アークガスによる内圧上昇に対して消弧カバー２を端子カバー３で拘束することにより、消弧カバー２の取付け強度を端子カバー３で補強する一方、端子カバー３を取り外せば、消弧カバー２を容易に取り外すことができるように構成されている。
特開２００５−３３２５８８号公報 For this reason, in the method disclosed in Patent Document 1, as shown in FIG. 10, the terminal cover 3 is fitted in a direction orthogonal to the fitting direction of the arc extinguishing cover 2, and the arc extinguishing cover 2 is set against an increase in internal pressure due to arc gas. By restraining with the terminal cover 3, the mounting strength of the arc-extinguishing cover 2 is reinforced with the terminal cover 3, while the arc-extinguishing cover 2 can be easily removed by removing the terminal cover 3.
JP 2005-332588 A

しかしながら、特許文献１に開示された方法では、端子カバー３による閂作用で消弧カバー２が外れるのを防止しているため、端子カバー３の使用が不可欠となり、端子カバー３なしでは、アークガスによる内圧上昇時に消弧カバー２が吹き飛ぶのを有効に防止することができないという問題があった。
そこで、本発明の目的は、端子カバーを使用することなく、アークガスによる内圧上昇時に消弧カバーが吹き飛ぶのを防止するとともに、消弧カバーの脱着を容易に行うことが可能な電磁接触器を提供することである。 However, in the method disclosed in Patent Document 1, since the arc-extinguishing cover 2 is prevented from being removed by the scissors action of the terminal cover 3, it is indispensable to use the terminal cover 3, and without the terminal cover 3, the arc gas is used. There has been a problem that it is not possible to effectively prevent the arc extinguishing cover 2 from blowing off when the internal pressure increases.
Accordingly, an object of the present invention is to provide an electromagnetic contactor that can prevent the arc-extinguishing cover from blowing off when the internal pressure is increased by the arc gas without using a terminal cover, and can easily attach and detach the arc-extinguishing cover. It is to be.

以上説明したように、本発明によれば、消弧カバーの対角の２箇所でフレームに篏合させるとともに、相対する対角の２箇所でフレームに篏合させないようにして、消弧カバーをフレームに固定することにより、アークガスによる内圧上昇が発生した場合においても、消弧カバーを対角の２箇所でフレームに固定したまま、相対する対角の２箇所で消弧カバーを浮かせてアークガスを外部に逃すことができ、内圧を低下させることができる。   As described above, according to the present invention, the arc-extinguishing cover is fitted to the frame at two diagonal positions of the arc-extinguishing cover and is not fitted to the frame at two opposite diagonal positions. By fixing to the frame, even if the internal pressure rises due to arc gas, the arc extinguishing cover is lifted at two opposite diagonal positions while the arc extinguishing cover is fixed to the frame at two diagonal positions. It can escape to the outside and the internal pressure can be reduced.

このため、端子カバーを使用することなく、アークガスによる内圧上昇時に消弧カバーが吹き飛ぶのを防止するとともに、消弧カバーの脱着を容易に行うことが可能となり、開閉動作による接点の消耗レベルを保守点検時に目視で確認できるとともに、短絡事故などで異常な高電流が流れた時に生じる高圧のアークエネルギーにより接点などの充電部が露出するのを防止することができる。   For this reason, it is possible to prevent the arc extinguishing cover from blowing off when the internal pressure rises due to arc gas without using a terminal cover, and it is possible to easily remove and attach the arc extinguishing cover, and maintain the contact consumption level due to opening and closing operations.

以下、本発明の実施形態に係る電磁接触器について図面を参照しながら説明する。
図１は、本発明の一実施形態に係る消弧カバーを裏側から見た構成を示す斜視図、図２は、本発明の一実施形態に係る電磁接触器の上部フレームに消弧カバーが装着された状態を部分的に切り欠いて示す斜視図、図３は、図２の電磁接触器の概略構成を示す裏面図、図４は、図２の電磁接触器の篏合部を拡大して示す断面図、図５は、本発明の一実施形態に係る電磁接触器のアークガスの排出状態を示す斜視図、図６は、本発明の一実施形態に係る電磁接触器の消弧カバーの取り外し方法を示す斜視図である。なお、図８および図９の電磁接触器の同一部分については同一符号を付し、説明を省略する。 Hereinafter, an electromagnetic contactor according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a configuration of an arc extinguishing cover according to an embodiment of the present invention as viewed from the back side, and FIG. 2 is an arc extinguishing cover attached to an upper frame of an electromagnetic contactor according to an embodiment of the present invention. FIG. 3 is a rear view showing a schematic configuration of the electromagnetic contactor of FIG. 2, and FIG. 4 is an enlarged view of the joint portion of the electromagnetic contactor of FIG. 2. FIG. 5 is a perspective view showing a discharge state of arc gas of the magnetic contactor according to the embodiment of the present invention, and FIG. 6 is removal of the arc extinguishing cover of the magnetic contactor according to the embodiment of the present invention. It is a perspective view which shows a method. In addition, the same code | symbol is attached | subjected about the same part of the electromagnetic contactor of FIG. 8 and FIG. 9, and description is abbreviate | omitted.

図１から図６において、消弧カバー１２の対角の２箇所には、上部フレーム１に篏合される篏合フック２ｂがそれぞれ設けられるとともに、相対する対角の２箇所には、上部フレーム１に篏合されない非篏合部２ｃが設けられている。ここで、篏合フック２ｂは、図１に示すように、消弧カバー１２に一体化され、ガス排出バリアまで延伸させることで、剛性を高め堅牢性を向上させることができる。   In FIG. 1 to FIG. 6, engagement hooks 2 b to be engaged with the upper frame 1 are respectively provided at two diagonal positions of the arc extinguishing cover 12, and the upper frame is disposed at two opposite diagonal positions. A non-mating portion 2c that is not mated to 1 is provided. Here, the union hook 2b is integrated with the arc-extinguishing cover 12, as shown in FIG. 1, and can extend to the gas discharge barrier, thereby increasing rigidity and improving robustness.

また、篏合フック２ｂには、図４に示すように、篏合フック２ｂの首元に形成された篏合面１２ｂと、篏合フック２ｂの先端に形成された篏合面１２ｃが設けられている。そして、電磁接触器の開閉動作による摩擦を低減しつつ、篏合フック２ｂが篏合フック１ａに押し当てられるようにするために、篏合面１２ｂには傾斜が形成されている。また、アークガスによる内圧上昇時に消弧カバー１２の抜け止めとしての効果を確保するために、篏合面１２ｃは、篏合フック１ａの篏合面に並行に面するように直角に構成されている。また、上部フレーム１には、篏合フック２ｂの根本に近接して配置された取り外し用角穴２ｄが形成されている。   As shown in FIG. 4, the mating hook 2b is provided with a mating surface 12b formed at the neck of the mating hook 2b and a mating surface 12c formed at the tip of the mating hook 2b. ing. In addition, an inclination is formed on the mating surface 12b so that the mating hook 2b is pressed against the mating hook 1a while reducing friction due to the opening / closing operation of the electromagnetic contactor. Further, in order to ensure the effect of retaining the arc extinguishing cover 12 when the internal pressure is increased by the arc gas, the mating surface 12c is configured at a right angle so as to face the mating surface of the mating hook 1a. . In addition, the upper frame 1 is formed with a detaching square hole 2d disposed in the vicinity of the root of the mating hook 2b.

そして、消弧カバー１２の篏合フック２ｂを上部フレーム１の篏合フック１ａに篏合することにより、消弧カバー１２の対角の２箇所で消弧カバー１２を上部フレーム１に篏合した上で、消弧カバー１２の相対する対角の２箇所が上部フレーム１に篏合されないようにして、消弧カバー１２を上部フレーム１に装着することができる。
これにより、アークガスによる内圧上昇が発生した場合においても、図５に示すように、消弧カバー１２を対角の２箇所で上部フレーム１に固定したまま、非篏合部２ｃの相対する対角の２箇所（非篏合部２ｃ）で消弧カバー１２を浮かせてアークガスを外部に逃すことができ、内圧を低下させることができる。 Then, the arc-extinguishing cover 12 is engaged with the upper frame 1 at two diagonal positions of the arc-extinguishing cover 12 by engaging the engaging hook 2b of the arc-extinguishing cover 12 with the engaging hook 1a of the upper frame 1. The arc extinguishing cover 12 can be attached to the upper frame 1 so that the two opposite diagonal portions of the arc extinguishing cover 12 are not engaged with the upper frame 1.
As a result, even when the internal pressure rises due to the arc gas, as shown in FIG. 5, the opposite corners of the non-joining portion 2 c remain while the arc extinguishing cover 12 is fixed to the upper frame 1 at two opposite corners. The arc extinguishing cover 12 can be floated at the two locations (non-mating portion 2c) to let the arc gas escape to the outside, and the internal pressure can be reduced.

このため、端子カバー３を使用することなく、アークガスによる内圧上昇時に消弧カバー１２が吹き飛ぶのを防止するとともに、消弧カバー１２の脱着を容易に行うことが可能となり、開閉動作による接点の消耗レベルを保守点検時に目視で確認できるとともに、短絡事故などで異常な高電流が流れた時に生じる高圧のアークエネルギーにより接点などの充電部が露出するのを防止することができる。   For this reason, without using the terminal cover 3, the arc extinguishing cover 12 can be prevented from blowing off when the internal pressure is increased by the arc gas, and the arc extinguishing cover 12 can be easily attached and detached. The level can be visually checked during maintenance and inspection, and it is possible to prevent exposure of charged parts such as contacts due to high-pressure arc energy generated when an abnormally high current flows due to a short circuit accident or the like.

また、消弧カバー１２を上部フレーム１から取り外す場合、図６に示すように、上部フレーム１の側面からマイナスドライバ５を取り外し用角穴２ｄに挿入しながら、取り外し用角穴２ｄを支点としてマイナスドライバ５を傾けることにより、消弧カバー１２を部分的に内側に変形させ、篏合フック２ｂの篏合面１２ｃをずらすことができる。
これにより、消弧カバー１２の対角の２箇所で上部フレーム１に強固に固定され、消弧カバー１２を素手では取り外すことができない場合においても、消弧カバー１２を上部フレーム１から容易に取り外すことができる。 Further, when the arc extinguishing cover 12 is removed from the upper frame 1, as shown in FIG. 6, the minus driver 5 is inserted into the removal square hole 2d from the side surface of the upper frame 1, and the removal square hole 2d is used as a fulcrum. By tilting the driver 5, the arc extinguishing cover 12 can be partially deformed inward, and the mating surface 12c of the mating hook 2b can be shifted.
Accordingly, even when the arc extinguishing cover 12 is firmly fixed to the upper frame 1 at two diagonal positions and the arc extinguishing cover 12 cannot be removed with bare hands, the arc extinguishing cover 12 is easily removed from the upper frame 1. be able to.
