従来、この種の可動接点ばねブロックを有する電磁継電器は、接極子および可 動接点ばねを備えた可動接点ばねブロックと、コイルを巻回し永久磁石およびコ 字形鉄心を装着したコイル組立体とを絶縁体基台に圧入した後、カバーをかぶせ て形成される。 Conventionally, an electromagnetic relay having this type of movable contact spring block insulates a movable contact spring block equipped with an armature and a movable contact spring from a coil assembly in which a coil is wound and a permanent magnet and a U-shaped iron core are mounted. It is formed by pressing on the body base and then covering it with a cover.

【0003】 図4はかかる従来の一例を示す電磁継電器の分解斜視図である。図4に示すよ うに、従来の電磁継電器は、可動接点2を有する可動接点ばね1A,ヒンジばね 3および接極子4を絶縁固定体5により一体化してなる可動接点ばねブロック6 と、コイル8を巻回したコイルスプール12に永久磁石9およびコ字形鉄心7を 装着するとともに両端にコイル端子13を形成してなるコイル組立体と、固定接 点10を被着した固定端子11,中立端子15およびコイル導出端子16を植設 し且つ可動接点ばねブロック6を搭載した前記コイル組立体を圧入固定するため の絶縁体基台14と、全体を覆うカバー17とを有している。特に、可動接点ば ねブロック6は可動接点2およびヒンジばね3を具備した可動接点ばね1Aが接 極子4の両側に配置され、絶縁固定体5により一体固定されている。また、コイ ル組立体は鉄心7の内側中央部に設けられたスプール12の穴部に永久磁石9を 固定することにより構成している。かかる電磁継電器においては、接極子4の傾 動運動が接極子下面中央部の突起(図示省略)を支点として行われる。前記突起 は永久磁石9の上面と適合して行われる。一方、絶縁体基台14のコイル導出端 子16はコイル組立体のコイル端子13と溶接等の方法で結合され、さらに可動 接点ばねブロック1Aのヒンジばね3と中立端子15が固着される。最後に、カ バー17を装着し、絶縁体基台14の下面とカバー17の内壁周辺部とに封止剤 を充填して継電器が構成される。上述した電磁継電器の可動接点ばねブロック6 を構成する可動接点ばね1Aは材質としてばね用銅合金が多く用いられている。FIG. 4 is an exploded perspective view of an electromagnetic relay showing such a conventional example. As shown in FIG. 4, the conventional electromagnetic relay includes a movable contact spring block 6 formed by integrating a movable contact spring 1A having a movable contact 2, a hinge spring 3 and an armature 4 with an insulating fixed body 5, and a coil 8. A coil assembly in which a permanent magnet 9 and a U-shaped iron core 7 are mounted on a wound coil spool 12 and coil terminals 13 are formed at both ends, a fixed terminal 11 to which a fixed contact 10 is attached, a neutral terminal 15 and It has an insulator base 14 for implanting the coil lead-out terminal 16 and for press-fitting and fixing the coil assembly on which the movable contact spring block 6 is mounted, and a cover 17 for covering the entire body. In particular, the movable contact spring block 6 has movable contact springs 1A having movable contacts 2 and hinge springs 3 arranged on both sides of the armature 4 and integrally fixed by an insulating fixed body 5. Further, the coil assembly is constructed by fixing a permanent magnet 9 in a hole portion of a spool 12 provided in the inner central portion of the iron core 7. In such an electromagnetic relay, the tilting movement of the armature 4 is performed with a protrusion (not shown) at the center of the lower surface of the armature as a fulcrum. The projections are made in conformity with the upper surface of the permanent magnet 9. On the other hand, the coil lead-out terminal 16 of the insulator base 14 is joined to the coil terminal 13 of the coil assembly by a method such as welding, and the hinge spring 3 and the neutral terminal 15 of the movable contact spring block 1A are fixed to each other. Finally, the cover 17 is attached, and the lower surface of the insulator base 14 and the peripheral portion of the inner wall of the cover 17 are filled with a sealant to form a relay. The movable contact spring 1A forming the movable contact spring block 6 of the electromagnetic relay described above is often made of spring copper alloy.

【考案が解決しようとする課題】[Problems to be solved by the device]

上述した従来の電磁継電器は、接点が閉成する時、可動接点が固定接点に衝突 することによりはね返るチャッタリングの現象が生じる。このチャッタリングに より可動接点ばねが振動してしまい、この振動がしばらく持続する。かかる振動 を継続している接点に電流が流れていると、チャッタリングにより継電器として は一度の動作であるが、接点は何度も電流の閉成を行うことになり、その寿命を 短くするという欠点がある。 In the above-described conventional electromagnetic relay, when the contacts are closed, the movable contact collides with the fixed contact, causing a phenomenon of chattering that rebounds. This chattering causes the movable contact spring to vibrate, and this vibration continues for a while. If a current flows through the contact that continues to vibrate like this, it is a one-time operation as a relay due to chattering, but the contact will repeatedly close the current, shortening its life. There are drawbacks.

【0005】 本考案の目的は、かかる可動接点のチャッタリングを防止し、長寿命化できる 電磁継電器を提供することにある。An object of the present invention is to provide an electromagnetic relay capable of preventing such movable contact chattering and extending the life thereof.

And a cover covering them, the coil assembly is fixed to the insulator base, and the projection at the center of the armature is fixed to the permanent magnet so that the movable contact spring block can be tilted. In the electromagnetic relay formed by contacting one end face with the fulcrum of the tilting motion of the armature and fixing the hinge spring to a part of the external output terminal, the movable contact spring block is formed. Contact spring is constituted by the vibration damping steel plate.

【実施例】【Example】

次に、本考案の実施例について図面を参照して説明する。 Next, an embodiment of the present invention will be described with reference to the drawings.

【0008】 図1は本考案の一実施例を説明するための電磁継電器における可動接点ばねブ ロックの斜視図である。図1に示すように、本実施例は前述した図4の従来例と 比較し、可動接点ばねブロック6以外は同一の構造である。すなわち、コイル組 立体や絶縁体基台14およびカバー17等は同一構造であるので、ここでは省略 している。本実施例における可動接点ばねブロック6は、可動接点2を先端に形 成した制振鋼板製の可動接点ばね1と、ヒンジばね3と、接極子4とを絶縁固定 体5により一体化している。かかる可動接点ばねブロック6は、図示していない コイル組立体のコイルに電流を流すことにより鉄心を励磁するので、接極子4は 傾動運動を行う。FIG. 1 is a perspective view of a movable contact spring block in an electromagnetic relay for explaining an embodiment of the present invention. As shown in FIG. 1, this embodiment has the same structure as the conventional example of FIG. 4 except for the movable contact spring block 6. That is, the coil assembly, the insulator base 14, the cover 17, and the like have the same structure and are omitted here. In the movable contact spring block 6 of this embodiment, a movable contact spring 1 made of a damping steel plate having a movable contact 2 at its tip, a hinge spring 3, and an armature 4 are integrated by an insulating fixed body 5. .. The movable contact spring block 6 excites the iron core by passing a current through a coil of a coil assembly (not shown), so that the armature 4 tilts.

【0009】 図2(a)〜(c)はそれぞれ図1に示す接極子の動作状態図である。図2( a)〜(c)に示すように、鉄心7とコイル8および永久磁石9により接極子4 が傾動運動を行うと、この接極子4に一体成型されている可動接点ばね1も傾動 運動を行い、可動接点2を固定端子11に被着された固定接点10に衝突させる 。2A to 2C are operation state diagrams of the armature shown in FIG. 1, respectively. As shown in FIGS. 2A to 2C, when the armature 4 is tilted by the iron core 7, the coil 8 and the permanent magnet 9, the movable contact spring 1 integrally molded with the armature 4 is also tilted. The movable contact 2 is caused to move and collide with the fixed contact 10 attached to the fixed terminal 11.

【0010】 図3(a)〜(c)はそれぞれ図2における可動接点の動作状態図である。図 3(a)に示すように、この状態は非動作状態である。可動接点2は固定接点1 0と所定の間隔をもって対向している。次に、図3(b)に示すように、この状 態は接点の閉成状態を表わす。可動接点ばね1が駆動され、可動接点2が固定接 点10に衝突すると、可動接点2ははね返りや振動を生ずるが、可動接点ばね1 は制振鋼板で形成されているので減振し、すぐに安定状態になる。更に、図3( c)に示すように、可動接点2が開離する時は、可動接点ばね1の自由振動と可 動接点2の重さにより発生する振動も制振鋼板であるので減振され、機械的な振 動を接極子4の周辺に及ぼすことを防止している。FIGS. 3A to 3C are operation state diagrams of the movable contact in FIG. As shown in FIG. 3A, this state is a non-operating state. The movable contact 2 faces the fixed contact 10 with a predetermined space. Next, as shown in FIG. 3B, this state represents the closed state of the contacts. When the movable contact spring 1 is driven and the movable contact 2 collides with the fixed contact point 10, the movable contact 2 rebounds or vibrates. Becomes stable. Further, as shown in FIG. 3 (c), when the movable contact 2 is separated, the vibration generated by the free vibration of the movable contact spring 1 and the weight of the movable contact 2 is also the damping steel plate, so the vibration is reduced. Therefore, mechanical vibration is prevented from being exerted around the armature 4.
