Description

本発明は、リレーに関する。 The present invention relates to a relay.

リレーには、主接点部と共に、主接点部の開閉に応じて開閉される補助接点を有するものがある。例えば、特許文献１に記載のリレーでは、電磁石の電磁力によって可動枠が駆動され、可動枠の動作に応じて主接点部が開閉されると共に、補助接点部が開閉される。この補助接点部の開閉状態を検出することにより、主接点部の開閉状態を検出することができる。 Some relays have an auxiliary contact that is opened and closed according to opening and closing of the main contact portion together with the main contact portion. For example, in the relay described in Patent Document 1, the movable frame is driven by the electromagnetic force of the electromagnet, the main contact portion is opened and closed according to the operation of the movable frame, and the auxiliary contact portion is opened and closed. By detecting the open / closed state of the auxiliary contact part, the open / closed state of the main contact part can be detected.

上述のようにリレーでは、主接点部を開閉するために、電磁石等の駆動部によって動作する可動部が備えられる。可動部は、駆動部からの駆動力によって移動し、その周囲の部材に接触する。そのため、可動部の周囲には、他の部材との接触による微小な磨耗粉が発生する。
ここで、主接点部は、比較的大きな電流を開閉する。そのため、微小な磨耗粉が発生しても、その影響は大きな問題にならない。しかし、補助接点部は、主接点部と比較して、微小な電流を開閉する。そのため、微小な磨耗粉であっても影響を受け易く、補助接点部の接触信頼を低下させるという問題が生じる。 As described above, the relay includes a movable part that is operated by a driving part such as an electromagnet in order to open and close the main contact part. The movable part is moved by the driving force from the driving part and comes into contact with the surrounding members. Therefore, minute wear powder is generated around the movable part due to contact with other members.
Here, the main contact portion opens and closes a relatively large current. Therefore, even if minute wear powder is generated, the effect is not a big problem. However, the auxiliary contact portion opens and closes a minute current compared to the main contact portion. Therefore, even if it is a minute wear powder, it is easy to be influenced and the problem of reducing the contact reliability of an auxiliary contact part arises.

本発明の課題は、補助接点部の接触信頼を向上させることができるリレーを提供することにある。 The subject of this invention is providing the relay which can improve the contact reliability of an auxiliary contact part.

本発明の一態様に係るリレーは、主接点部と、補助接点部と、駆動部と、可動部と、接触部と、壁部と、を備える。補助接点部は、補助接点を含み、主接点部の開閉に応じて開閉される。補助接点部には、主接点部に流れる電流よりも小さな電流が流れる。駆動部は、主接点部を開閉するための駆動力を発生させる。可動部は、駆動部からの駆動力によって動作する。接触部は、可動部と接触するように設けられる。壁部は、補助接点と接触部とを接続する空間の少なくとも一部を遮る位置に配置される。 The relay which concerns on 1 aspect of this invention is provided with a main contact part, an auxiliary contact part, a drive part, a movable part, a contact part, and a wall part. The auxiliary contact portion includes an auxiliary contact, and is opened and closed according to the opening and closing of the main contact portion. A current smaller than the current flowing through the main contact portion flows through the auxiliary contact portion. The driving unit generates a driving force for opening and closing the main contact part. The movable part operates by a driving force from the driving part. The contact portion is provided so as to contact the movable portion. The wall portion is disposed at a position that blocks at least a part of the space connecting the auxiliary contact and the contact portion.

本態様に係るリレーでは、壁部が、可動部との接触によって磨耗粉の発生源となり得る接触部と、磨耗粉による影響を受け易い補助接点とを接続する空間の少なくとも一部を遮る位置に配置される。このため、接触部において磨耗粉が発生しても、磨耗粉が接触部から補助接点に到達することを妨げることができる。言い換えれば、接触部と補助接点とは同じ空間内にあり、接触部で発生した摩耗粉などの粉塵が補助接点に到達するのを妨げる位置に壁部が配置される。これにより、補助接点部の接触信頼を向上させることができる。 In the relay according to this aspect, the wall portion is located at a position that blocks at least a part of the space connecting the contact portion that can be a source of wear powder due to contact with the movable portion and the auxiliary contact that is easily affected by the wear powder. Be placed. For this reason, even if wear powder is generated in the contact portion, it is possible to prevent the wear powder from reaching the auxiliary contact from the contact portion. In other words, the contact portion and the auxiliary contact are in the same space, and the wall portion is arranged at a position that prevents dust such as wear powder generated at the contact portion from reaching the auxiliary contact.

第２補助接触片４２の上部は押圧部４２２を有する。リンク部１５の第２端部１５２が第２補助接触片４２の押圧部４２２を押圧することにより、図４に示すように、第２補助接触片４２が第１補助接触片４１に近づく方向に撓む。それにより、第２補助接点４４が第１補助接点４３に接触する。また、リンク部１５の第２端部１５２が第２補助接触片４２の押圧部４２２から離れることにより、図５に示すように、第２補助接触片４２の弾性力によって、第２補助接触片４２が元の状態に復帰する。それにより、第２補助接点４４が第１補助接点４３から離れる。このようにして、補助接点部１７は、リンク部１５の動作によって開閉される。 The upper part of the second auxiliary contact piece 42 has a pressing part 422. When the second end 152 of the link portion 15 presses the pressing portion 422 of the second auxiliary contact piece 42, the second auxiliary contact piece 42 approaches the first auxiliary contact piece 41 as shown in FIG. 4. Bend. As a result, the second auxiliary contact 44 contacts the first auxiliary contact 43. Further, when the second end 152 of the link portion 15 is separated from the pressing portion 422 of the second auxiliary contact piece 42, the second auxiliary contact piece is caused by the elastic force of the second auxiliary contact piece 42 as shown in FIG. 42 returns to the original state. As a result, the second auxiliary contact 44 is separated from the first auxiliary contact 43. In this way, the auxiliary contact portion 17 is opened and closed by the operation of the link portion 15.

図６及び図７に示すように、第１補助接触片４１には第１壁部５１が設けられている。第２補助接触片４２には第２壁部５２が設けられている。第１壁部５１と第２壁部５２とは、第１補助接点４３と第２補助接点４４とに対向するように配置される。すなわち、第１壁部５１と第２壁部５２とは、第１補助接点４３及び第２補助接点４４と、概ね同じ高さに配置されている。第１壁部５１と第２壁部５２とは、押圧部４２２よりも下方に位置する。 As shown in FIGS. 6 and 7, the first auxiliary contact piece 41 is provided with a first wall portion 51.

The The second wall 52 is formed integrally with the second auxiliary contact piece 42. Specifically, the second auxiliary contact piece 42 and the second wall 52 are formed of an integral plate member, and the second wall 52 is formed by bending a part of the plate member. The However, the first wall portion 51 does not need to be formed integrally with the first auxiliary contact piece 41, and connects the first auxiliary contact 43 and the second auxiliary contact 44 to the first contact portion 241 of the second yoke 24. As long as it is arranged at a position that blocks the space to be performed, it may be formed separately. The second wall portion 52 does not need to be formed integrally, and is disposed at a position that blocks the space connecting the first auxiliary contact 43 and the second auxiliary contact 44 and the first link contact portion 155 of the link portion 15. If so, it may be formed separately from the second auxiliary contact piece 42.

次に、リレー１の動作について説明する。図２及び図４に示すリセット状態では、第１接極子２５の第１端部２５１が第１ヨーク２３と接触し、第２端部２５２が第２ヨーク２４から離れている。また、第２接極子２６の第４端部２６２が第２ヨーク２４と接触し、第３端部２６１が第１ヨーク２３から離れている。可動接点３４は固定接点３５から離れている。また、連結部２８２はリンク部１５の第１リンク接触部１５５に接触しており、リンク部１５は第２補助接触片４２を押圧している。そのため、第２補助接点４４は第１補助接点４３に接触している。 Next, the operation of the relay 1 will be described. In the reset state shown in FIGS. 2 and 4, the first end 251 of the first armature 25 is in contact with the first yoke 23, and the second end 252 is separated from the second yoke 24. Further, the fourth end 262 of the second armature 26 is in contact with the second yoke 24, and the third end 261 is separated from the first yoke 23. The movable contact 34 is separated from the fixed contact 35. The connecting portion 282 is in contact with the first link contact portion 155 of the link portion 15, and the link portion 15 presses the second auxiliary contact piece 42. Therefore, the second auxiliary contact 44 is in contact with the first auxiliary contact 43.

コイル２１に所定方向に通電すると、可動部１３を順方向（図２における時計回り）に回転させる電磁力が発生する。これにより、可動部１３が順方向に回転する。可動部１３が順方向に回転すると、連結部２８２がリンク部１５の第２リンク接触部１５６に接触して押圧することで、リンク部１５が図２における左方向に移動する。これにより、可動接触片３１の先端が図２における左方向に移動し、それと共に、可動接点３４が固定接点３５に近づく方向に移動する。その結果、可動接点３４が固定接点３５に接触する。これにより、リレー１は、図２に示すリセット状態から図３に示すセット状態に切り換えられる。また、このとき、リンク部１５が第２補助接触片４２から離れることで、第２補助接点４４が第１補助接点４３から離れる。 When the coil 21 is energized in a predetermined direction, an electromagnetic force that rotates the movable portion 13 in the forward direction (clockwise in FIG. 2) is generated. Thereby, the movable part 13 rotates in the forward direction. When the movable portion 13 rotates in the forward direction, the connecting portion 282 contacts and presses the second link contact portion 156 of the link portion 15 so that the link portion 15 moves to the left in FIG. Thereby, the tip of the movable contact piece 31 moves to the left in FIG. 2, and at the same time, the movable contact 34 moves in a direction approaching the fixed contact 35. As a result, the movable contact 34 contacts the fixed contact 35. Thereby, the relay 1 is switched from the reset state shown in FIG. 2 to the set state shown in FIG. At this time, the second auxiliary contact 44 is separated from the first auxiliary contact 43 because the link portion 15 is separated from the second auxiliary contact piece 42.

図３及び図５に示すように、セット状態では、第１接極子２５の第１端部２５１が第１ヨーク２３から離れ、第２端部２５２が第２ヨーク２４に接触する。また、第２接極子２６の第４端部２６２が第２ヨーク２４から離れ、第３端部２６１が第１ヨーク２３に接触する。なお、この状態でコイル２１への通電が停止されても、永久磁石２７の磁力により、セット状態が維持される。 As shown in FIGS. 3 and 5, in the set state, the first end 251 of the first armature 25 is separated from the first yoke 23, and the second end 252 is in contact with the second yoke 24. Further, the fourth end 262 of the second armature 26 is separated from the second yoke 24, and the third end 261 is in contact with the first yoke 23. In this state, even when energization of the coil 21 is stopped, the set state is maintained by the magnetic force of the permanent magnet 27.

次に、コイル２１に上記の所定方向と逆の方向に通電すると、可動部１３を上記の順方向と逆方向（図３における反時計回り）に回転させる電磁力が発生する。これにより、可動部１３が逆方向に回転する。可動部１３が逆方向に回転すると、連結部２８２がリンク部１５の第１リンク接触部１５５に接触して押圧することで、リンク部１５が図３における右方向に移動する。これにより、可動接触片３１の先端が図３における右方向に移動し、それと共に、可動接点３４が固定接点３５から離れる方向に移動する。その結果、可動接点３４が固定接点３５から離れる。これにより、リレー１は、図３に示すセット状態から図２に示すリセット状態に戻る。また、このとき、リンク部１５が第２補助接触片４２を押圧することで、第２補助接点４４が第１補助接点４３に接触する。なお、この状態でコイル２１への通電が停止されても、永久磁石２７の磁力により、リセット状態が維持される。 Next, when the coil 21 is energized in the direction opposite to the predetermined direction, an electromagnetic force that rotates the movable portion 13 in the direction opposite to the forward direction (counterclockwise in FIG. 3) is generated. Thereby, the movable part 13 rotates in the reverse direction. When the movable portion 13 rotates in the reverse direction, the connecting portion 282 contacts and presses the first link contact portion 155 of the link portion 15 so that the link portion 15 moves to the right in FIG. As a result, the tip of the movable contact piece 31 moves to the right in FIG. 3, and at the same time, the movable contact 34 moves away from the fixed contact 35. As a result, the movable contact 34 is separated from the fixed contact 35. Thereby, the relay 1 returns from the set state shown in FIG. 3 to the reset state shown in FIG. At this time, the second auxiliary contact 44 contacts the first auxiliary contact 43 by the link portion 15 pressing the second auxiliary contact piece 42. In this state, even if energization of the coil 21 is stopped, the reset state is maintained by the magnetic force of the permanent magnet 27.

以上説明した、本実施形態に係るリレー１では、第１壁部５１と第２壁部５２とが、第１補助接点４３及び第２補助接点４４が配置される空間の両側方を覆っている。このため、第１〜第４接触部２４１，２４２，２３１，２３２、或いは第１、第２リンク接触部１５５，１５６において磨耗粉が発生しても、磨耗粉が各接触部から補助接点部１７に到達することを妨げることができる。 In the relay 1 according to the present embodiment described above, the first wall portion 51 and the second wall portion 52 cover both sides of the space in which the first auxiliary contact 43 and the second auxiliary contact 44 are disposed. . For this reason, even if wear powder is generated in the first to fourth contact portions 241, 242, 231, 232, or the first and second link contact portions 155, 156, the wear powder is transferred from each contact portion to the auxiliary contact portion 17. Can be prevented from reaching.

特に、第１壁部５１は、補助接点部１７に近接して配置される第２ヨーク２４と可動部１３との接触部（第１接触部２４１）と、補助接点部１７との間に配置される。このため、第１接触部２４１において磨耗粉が発生しても、磨耗粉が第１接触部２４１から補助接点部１７に到達することを妨げることができる。
また、第２壁部５２は、補助接点部１７に近接して配置されるリンク部１５と可動部１３との接触部（第１リンク接触部１５５）と、補助接点部１７との間に配置される。このため、第１リンク接触部１５５において磨耗粉が発生しても、磨耗粉が第１リンク接触部１５５から補助接点部１７に到達することを妨げることができる。 In particular, the first wall portion 51 is disposed between a contact portion (first contact portion 241) between the second yoke 24 and the movable portion 13 disposed in the vicinity of the auxiliary contact portion 17 and the auxiliary contact portion 17. Is done. For this reason, even if wear powder is generated in the first contact portion 241, it is possible to prevent the wear powder from reaching the auxiliary contact portion 17 from the first contact portion 241.
Further, the second wall portion 52 is disposed between the contact portion (first link contact portion 155) between the link portion 15 and the movable portion 13 disposed close to the auxiliary contact portion 17 and the auxiliary contact portion 17. Is done. For this reason, even if wear powder is generated in the first link contact portion 155, it is possible to prevent the wear powder from reaching the auxiliary contact portion 17 from the first link contact portion 155.

以上のように、本実施形態に係るリレー１では、磨耗粉が補助接点部１７に到達することを妨げることができる。それにより、第１、第２補助接点４３，４４に磨耗粉が付着することを抑えることができる。その結果、補助接点部１７の接触信頼を向上させることができる。
