Description

本発明は、リレー、特にパワー負荷用のリレーに関するものである。 The present invention relates to a relay, particularly a power load relay.

従来から種々のリレーが提供されており、この種のリレーとしては、例えば、固定接点および当該固定接点に接離する可動接点を封止容器に収納してなる封止接点装置と、コイルで発生する電磁界により固定接点と接離するように可動接点を移動させる（すなわち封止接点装置を駆動する）電磁石装置とで構成される内器ブロックを備えた電磁継電器が提案されている（例えば、特許文献１参照）。 Various relays have been provided in the past. Examples of this type of relay include a fixed contact and a sealed contact device in which a movable contact contacting and leaving the fixed contact is housed in a sealed container, and a coil. An electromagnetic relay having an inner unit block composed of an electromagnetic device that moves a movable contact (that is, drives a sealed contact device) so as to come into contact with and away from a fixed contact by an electromagnetic field is proposed (for example, Patent Document 1).

内器ブロックは、例えば、図１８に示すような絶縁材料製のケース１００に収納される。ケース１００は、一面側が開口された箱状のボディ１１０と、当該ボディの開口を閉塞する形でボディ１１０に取り付けられるカバー１２０とで構成される。このボディ１１０とカバー１２０との間の内部空間に上記の内器ブロック（封止接点装置および電磁石装置）が収納される。ところで、ケース１００には、図示しない内器ブロックを構成する電磁石装置のコイルに給電するための端子（コイル給電用端子）２００が２個備えられる。 For example, the inner block is housed in a case 100 made of an insulating material as shown in FIG. The case 100 includes a box-shaped body 110 that is open on one side, and a cover 120 that is attached to the body 110 so as to close the opening of the body. The inner unit block (sealed contact device and electromagnet device) is housed in an internal space between the body 110 and the cover 120. By the way, the case 100 is provided with two terminals (coil feeding terminals) 200 for feeding power to the coils of the electromagnet device that constitutes an inner unit block (not shown).

コイル給電用端子２００としては、図１９（ａ），（ｂ）に示すように、ケース１００外に突出され、外部装置（図示せず）に接続される矩形板状の外側端子部２１０と、ケース１００内に位置し、電磁石装置のコイルと電線３００で接続される内側端子部２２０とを一体に備えたものがある。内側端子部２２０は、電線３００を載置する板状の載置部２２１と、載置部２２１に電線３００を固定する固定部２２２とを一体に備える。 As shown in FIGS. 19A and 19B, the coil power supply terminal 200 protrudes out of the case 100 and is connected to an external device (not shown). There are some which are located in the case 100 and integrally include the coil of the electromagnet device and the inner terminal portion 220 connected by the electric wire 300. The inner terminal portion 220 integrally includes a plate-like placement portion 221 for placing the electric wire 300 and a fixing portion 222 for fixing the electric wire 300 to the placement portion 221.

ここで、固定部２２２は、載置部２２１の縁部（図示例では、長さ方向一縁部＜図１９（ａ）における上縁部＞）に一体に突設された長尺状の突片２２２ａを、図２０において矢印Ｘで示すように、その先部２２２ｂが載置部２２１と厚み方向で重なるように曲成してなるものである。電線３００は、固定部２２２の先部２２２ａと載置部２２１との間で狭持される。このように上記従来例のリレーでは、内側端子部２００は電線３００を載置部２２１に固定する固定部２２２を備えるから、コイルとの接続に使用する電線３００をコイル給電用端子２００に容易に固定することができる。
特開２０００−１２３７０２号公報 Here, the fixing portion 222 is a long protrusion integrally projecting from the edge portion of the placement portion 221 (in the illustrated example, one edge portion in the length direction <upper edge portion in FIG. 19A>). As shown by an arrow X in FIG. 20, the piece 222 a is bent so that the tip portion 222 b overlaps the placement portion 221 in the thickness direction. The electric wire 300 is held between the tip portion 222 a of the fixing portion 222 and the placement portion 221. As described above, in the relay according to the conventional example, the inner terminal portion 200 includes the fixing portion 222 that fixes the electric wire 300 to the mounting portion 221, so that the electric wire 300 used for connection with the coil can be easily used as the coil feeding terminal 200.

上述したコイル給電用端子２００を製造するにあたっては、コイル給電用端子２００の基礎部品を金属板の打ち抜き加工により形成し、当該基礎部品を折曲する方法が一般的である。ここで、図１９に示すコイル給電用端子２００は、電線３００を載置部２２１に固定するために固定部２２２を備えており、固定部２２２は、載置部２２１の縁部に一体に突設された突片２２２ａより曲成されたものであるから、固定部２２２を設けない場合に比べれば、上記基礎部品のサイズが大きくなって、上記基礎部品を金属板より打ち抜くために必要な面積が大きくなる。また、突片２２２ａを形成するためだけに上記基礎部品のサイズを大きくしなければならないから、コイル給電用端子２００を製造する際の金属板の材料ロスも多くなってしまう。その結果、コイル給電用端子２００の製造コストが高くなり、このことがリレーの高コスト化の一因となっていた。 In manufacturing the above-described coil power supply terminal 200, a general method is to form a basic component of the coil power supply terminal 200 by punching a metal plate and bend the basic component. Here, the coil feeding terminal 200 shown in FIG. 19 includes a fixing portion 222 for fixing the electric wire 300 to the mounting portion 221, and the fixing portion 222 projects integrally with the edge of the mounting portion 221. Since it is bent from the provided projecting piece 222a, the size of the foundation part is larger than that in the case where the fixing part 222 is not provided, and the area necessary for punching the foundation part from the metal plate Becomes larger. Further, since the size of the basic part has to be increased only for forming the projecting piece 222a, the material loss of the metal plate when the coil power supply terminal 200 is manufactured also increases. As a result, the manufacturing cost of the coil power supply terminal 200 is increased, and this is one factor in increasing the cost of the relay.

本発明は上述の点に鑑みて為されたもので、その目的は、コイルとの接続に使用する電線をコイル給電用端子に容易に固定することができ、しかも低コスト化を図ることができるリレーを提供することにある。 The present invention has been made in view of the above-described points, and an object of the present invention is to easily fix an electric wire used for connection with a coil to a coil feeding terminal, and to achieve cost reduction.

The joint between the yoke part 15 and the sealing container 10 and the sealing member 18 is performed by brazing or the like, and the gap between the yoke part 15 and the sealing member 18 or between the sealing member 18 and the sealing container 10 is performed. Is sealed.

固定鉄芯１７は、磁性材料により円筒状に形成される。固定鉄芯１７は軸方向一端部（図４（ａ）における上端部）を継鉄部１５の開口部１５ａ内に配置した状態で、継鉄部１５に固定される。この固定鉄芯１７の内径は、復帰バネＳ２の外径よりやや大きく設定され、これによって、復帰バネＳ２は、底カバー１４と可動鉄芯１６との間に介在される。なお、復帰バネＳ２の内径は、シャフト１３の外径よりやや大きく設定され、シャフト１３は復帰バネＳ２を貫挿する形で配置される。前述の可動鉄芯（プランジャ）１６は、固定鉄芯１７の外径と同程度の大きさの外径を有する円柱状に形成される。可動鉄芯１６には、シャフト１３の軸方向他端部が螺着されるネジ孔１６ａが貫設される。また、可動鉄芯１６の外周面には、軸方向に溝部（図示せず）が形成される。ところで、復帰バネＳ２はコイルスプリングからなり、上述したように底カバー１４と可動鉄芯１６との間に介在される。そのため、電磁石装置２で電磁界が発生していない常時は、可動鉄芯１６は復帰バネＳ２により固定鉄芯１７より離間させられ（図４（ａ）における下側に移動させられ）、可動接点は固定接点１１ｂより離間する。 The fixed iron core 17 is formed in a cylindrical shape from a magnetic material. The fixed iron core 17 is fixed to the yoke portion 15 with one axial end portion (the upper end portion in FIG. 4A) disposed in the opening 15 a of the yoke portion 15. The inner diameter of the fixed iron core 17 is set to be slightly larger than the outer diameter of the return spring S 2, whereby the return spring S 2 is interposed between the bottom cover 14 and the movable iron core 16. The inner diameter of the return spring S2 is set to be slightly larger than the outer diameter of the shaft 13, and the shaft 13 is disposed so as to penetrate the return spring S2. The aforementioned movable iron core (plunger) 16 is formed in a cylindrical shape having an outer diameter that is approximately the same as the outer diameter of the fixed iron core 17. The movable iron core 16 is provided with a screw hole 16a through which the other axial end of the shaft 13 is screwed. In addition, a groove (not shown) is formed in the axial direction on the outer peripheral surface of the movable iron core 16. By the way, the return spring S2 is formed of a coil spring and is interposed between the bottom cover 14 and the movable iron core 16 as described above. Therefore, at any time when no electromagnetic field is generated in the electromagnet device 2, the movable iron core 16 is separated from the fixed iron core 17 by the return spring S2 (moved downward in FIG. 4A), and the movable contact point. Is separated from the fixed contact 11b.

継鉄部１５における封止容器１０側とは反対側（図４（ａ）における下側）には、可動鉄芯１６および固定鉄芯１７を収容するキャップ部（プランジャキャップ）１９が取り付けられる。キャップ部１９は、非磁性材料により形成され、可動鉄芯１６および固定鉄芯１７の外径よりやや大きい内径を有する有底円筒状の収容部１９ａを備える。収容部１９ａの軸方向の長さは、可動鉄芯１６の移動によって、可動接点と固定接点１１ｂとが接離可能な長さに設定される。また、収容部１９ａの内周面は、可動鉄芯１６が摺動する摺動面を構成し、この内周面には可動鉄芯１６の溝部に嵌まる突部（図示せず）が突設される。つまり、可動鉄芯１６の溝部とキャップ部１９の突部とで、可動鉄芯１６を回転などさせずに軸方向に移動させるガイドが構成される。ところで、収容部１９ａの開口端側には、円盤状の鍔部１９ｂが一体に形成される。キャップ部１９は、鍔部１９ｂを継鉄部１５にレーザ溶接することによって、継鉄部１５に気密接合される。 A cap part (plunger cap) 19 that houses the movable iron core 16 and the fixed iron core 17 is attached to the side opposite to the sealing container 10 side in the yoke part 15 (the lower side in FIG. 4A). The cap portion 19 is formed of a nonmagnetic material and includes a bottomed cylindrical accommodating portion 19 a having an inner diameter slightly larger than the outer diameter of the movable iron core 16 and the fixed iron core 17. The axial length of the accommodating portion 19a is set to a length that allows the movable contact 16 and the fixed contact 11b to be contacted and separated by the movement of the movable iron core 16. Further, the inner peripheral surface of the accommodating portion 19a constitutes a sliding surface on which the movable iron core 16 slides, and a protrusion (not shown) that fits into the groove portion of the movable iron core 16 protrudes from this inner peripheral surface. Established. That is, the groove portion of the movable iron core 16 and the protrusion of the cap portion 19 constitute a guide that moves the movable iron core 16 in the axial direction without rotating it. By the way, a disc-shaped flange portion 19b is integrally formed on the opening end side of the accommodating portion 19a. The cap portion 19 is hermetically joined to the yoke portion 15 by laser welding the flange portion 19b to the yoke portion 15.

電磁石装置２は、コイルブロック２０と、前述の継鉄ブロック２１とで構成される。この電磁石装置２は、コイルブロック２０のコイルＬに電流を流して励磁して、固定鉄芯１７に可動鉄芯１６を吸引させることにより、封止接点装置１の駆動を行う。 The electromagnet device 2 includes a coil block 20 and the yoke block 21 described above. The electromagnet device 2 drives the sealed contact device 1 by energizing and exciting the coil L of the coil block 20 by attracting the movable iron core 16 to the fixed iron core 17.

コイルブロック２０は、コイルＬと、当該コイルＬを保持するコイルボビン２２とを備える。コイルボビン２２は、絶縁性材料により形成され、コイルＬを構成する電線が巻装される円筒状の巻胴部２２ａを備える。巻胴部２２ａの内径は、キャップ部１９の収容部１９ａの外径よりやや大きく設定される。つまり、コイルボビン２２内に、キャップ部１９の収容部１９ａを挿入できるようにしている。ただし、巻胴部２０ｂの軸方向他端側（図４（ａ）における下端側）における内径は、後述する円筒部２４の外径よりやや大きく設定される。これによって、コイルボビン２２の軸方向他端側においては、キャップ部１９の収容部１９ａとコイルボビン２２との間に、円筒部２４が介在可能となる。この巻胴部２２ａの軸方向一端側（図４（ａ）における上端側）には、矩形板状の第１の鍔部２２ｂが、軸方向他端側（図４（ａ）における下端側）には、矩形板状の第２の鍔部２２ｃがそれぞれ一体に形成される。 The coil block 20 includes a coil L and a coil bobbin 22 that holds the coil L. The coil bobbin 22 is formed of an insulating material and includes a cylindrical winding body 22a around which an electric wire constituting the coil L is wound. The inner diameter of the winding drum portion 22 a is set slightly larger than the outer diameter of the accommodating portion 19 a of the cap portion 19. That is, the accommodating portion 19 a of the cap portion 19 can be inserted into the coil bobbin 22. However, the inner diameter on the other axial end side (the lower end side in FIG. 4A) of the winding body 20b is set to be slightly larger than the outer diameter of the cylindrical part 24 described later. Accordingly, the cylindrical portion 24 can be interposed between the accommodating portion 19 a of the cap portion 19 and the coil bobbin 22 on the other axial end side of the coil bobbin 22. On one end side in the axial direction of the winding drum portion 22a (upper end side in FIG. 4A), the first flange portion 22b having a rectangular plate shape is on the other end side in the axial direction (lower end side in FIG. 4A). Are formed integrally with a rectangular plate-like second flange 22c.

第１の鍔部２２ｂには、コイルＬの両端部それぞれを接続する一対の接続端子２３が設けられる。接続端子２３は、例えば金属板より打ち抜き形成され、コイルＬの端部が絡げられる絡げ部２３ａと、電線３００が半田付けなどにより接続される接続部２３ｂとを一体に備える。また、接続部２３ｂには、電線３００を接続部２３ｂに固定するかしめ部２３ｃが一体に設けられる。第２の鍔部２２ｃには、図４（ａ）に示すように、継鉄ブロック２１の後述する連結板２１ｂと凹凸嵌合する凹所２２ｄが形成される。 The first flange portion 22b is provided with a pair of connection terminals 23 that connect both ends of the coil L. For example, the connection terminal 23 is formed by punching from a metal plate, and integrally includes a binding portion 23a where the end of the coil L is bound and a connection portion 23b where the electric wire 300 is connected by soldering or the like. The connecting portion 23b is integrally provided with a caulking portion 23c that fixes the electric wire 300 to the connecting portion 23b. As shown in FIG. 4 (a), a recess 22d is formed in the second flange portion 22c to be engaged with a connecting plate 21b (described later) of the yoke block 21.

継鉄ブロック２１は、磁性金属材料（例えば鉄など）によりコ字状に形成される。さらに詳しく説明すると、継鉄ブロック２１は、互いに並行配置された一対の側板２１ａと、両側板２１ａの基端部同士を一体に連結する前述の連結板２１ｂとを一体に備える。一対の側板２１ａ間の間隔は、側板２１ａ間にコイルブロック２０を配置できる大きさに設定される。各側板２１ａの先端部それぞれには、継鉄部１５の嵌合突起１５ｂと凹凸嵌合する嵌合凹部２１ｃが形成される。また連結板２１ｂの中央部には、前述の円筒部２４が設けられる。この円筒部２４の内側には、コイルボビン２２の内側を挿通したキャップ部１９の収容部１９ａが挿入される。 The yoke block 21 is formed in a U shape by a magnetic metal material (for example, iron). More specifically, the yoke block 21 is integrally provided with a pair of side plates 21a arranged in parallel to each other and the above-described connecting plate 21b that integrally connects the base end portions of the both side plates 21a. The distance between the pair of side plates 21a is set to a size that allows the coil block 20 to be disposed between the side plates 21a. A fitting recess 21c is formed at each end of each side plate 21a so as to fit with the fitting protrusion 15b of the yoke portion 15. In addition, the above-described cylindrical portion 24 is provided in the central portion of the connecting plate 21b. Inside the cylindrical portion 24, the accommodating portion 19a of the cap portion 19 inserted through the inside of the coil bobbin 22 is inserted.

電磁石装置２は、継鉄ブロック２１の両側板２１ａおよび連結板２１ｂで囲まれる空間部に、コイルブロック２０を配置することにより構成される。 The electromagnet device 2 is configured by arranging the coil block 20 in a space portion surrounded by the both side plates 21a and the connecting plate 21b of the yoke block 21.

ところで、内器ブロックＢＫは、封止接点装置１と電磁石装置２とに加えて、封止接点装置１における固定接点１１ａと可動接点との間に生じるアークを短時間で消去するためのカプセルヨーク４を備える。このカプセルヨーク４は、図４（ａ），（ｂ）に示すように、磁性金属材料（例えば鉄など）により、例えば、封止容器１０の短手方向（図４（ａ）における左右方向）両側面それぞれに対向配置された一対の側片４０ａと、側片同士を一体に連結する連結片４０ｂとを一体に備えた保持部材４０を備える。この保持部材４０の一対の側片４０ａそれぞれには、永久磁石４１が取り付けられる。この構成により、カプセルヨーク４は、固定接点１１ｂと可動接点との接離方向に交差する方向の磁場を発生し、当該磁場によって、固定接点１１ｂと可動接点との間に生じたアークが引き伸ばされ、短時間での消去が可能となる。 By the way, in addition to the sealed contact device 1 and the electromagnet device 2, the inner unit block BK is a capsule yoke for erasing arcs generated between the fixed contact 11a and the movable contact in the sealed contact device 1 in a short time. 4 is provided. As shown in FIGS. 4A and 4B, the capsule yoke 4 is made of a magnetic metal material (for example, iron), for example, in the short direction of the sealing container 10 (left and right direction in FIG. 4A). The holding member 40 is integrally provided with a pair of side pieces 40a disposed opposite to both side surfaces and a connecting piece 40b that integrally connects the side pieces. A permanent magnet 41 is attached to each of the pair of side pieces 40 a of the holding member 40. With this configuration, the capsule yoke 4 generates a magnetic field in a direction crossing the contact / separation direction of the fixed contact 11b and the movable contact, and the arc generated between the fixed contact 11b and the movable contact is stretched by the magnetic field. It becomes possible to erase in a short time.

次に、本実施形態のリレーの動作（内器ブロックＢＫの動作）について簡単に説明する。本実施形態のリレーは、上述したように常開型のものであり、電磁石装置２のコイルＬに通電されていない状態では、図４（ａ），（ｂ）に示すように、接圧バネＳ１のバネ力によって可動接触子１２は固定接点１１ｂ側へ移動しようとするが、このような可動接触子１２の移動はシャフト１３の規制部１３ａによって規制される。したがって、電磁石装置２のコイルＬに通電されていない状態では、可動接触子１２の各可動接点がそれぞれ対応する固定接点１１ｂから離間した状態であるから、接点はオフである。この状態において、固定接点１１ｂ間は絶縁されている。 Next, the operation of the relay of this embodiment (the operation of the internal unit block BK) will be briefly described. As described above, the relay according to the present embodiment is a normally open type, and in a state in which the coil L of the electromagnet device 2 is not energized, as shown in FIGS. Although the movable contact 12 tends to move toward the fixed contact 11b by the spring force of S1, such movement of the movable contact 12 is regulated by the regulating portion 13a of the shaft 13. Therefore, in a state where the coil L of the electromagnet device 2 is not energized, each movable contact of the movable contact 12 is in a state of being separated from the corresponding fixed contact 11b, and thus the contact is off. In this state, the fixed contacts 11b are insulated.

そして、電磁石装置２のコイルＬへの通電が開始されると（コイルＬが励磁されると）、可動鉄芯１６が固定鉄芯１７に吸引される。これによって、可動鉄芯１６は、復帰バネＳ２の付勢に逆らってシャフト１３とともに固定鉄芯１７に近接する方向（図４（ａ）における上方向）へ移動していく。その結果、シャフト１３の規制部１３ａによる可動接触子１２の移動規制が解除されるから、可動接触子１２の各可動接点がそれぞれ対応する固定接点１１ｂに接触して接点がオンとなり、固定接点１１ｂ間が可動接触子１２により短絡される。このとき、可動接点と固定接点１１ｂとは、接圧バネＳ１のバネ力によって所定接圧で接触することになる。 When energization of the coil L of the electromagnet device 2 is started (when the coil L is excited), the movable iron core 16 is attracted to the fixed iron core 17. As a result, the movable iron core 16 moves in the direction approaching the fixed iron core 17 together with the shaft 13 (upward in FIG. 4A) against the urging force of the return spring S2. As a result, the movement restriction of the movable contact 12 by the restriction portion 13a of the shaft 13 is released, so that each movable contact of the movable contact 12 comes into contact with the corresponding fixed contact 11b to turn on the contact, and the fixed contact 11b. The space is short-circuited by the movable contact 12. At this time, the movable contact and the fixed contact 11b come into contact with each other with a predetermined contact pressure by the spring force of the contact pressure spring S1.

その後に、電磁石装置２のコイルＬへの通電が終了すると（コイルＬの励磁が終了すると）、可動鉄芯１６は固定鉄芯１７に吸引されなくなるから、復帰バネＳ２のバネ力によって、固定鉄芯１７から離間する方向（図４（ａ）における下方向）へ移動する。そのため、可動接触子１２は、シャフト１３の規制部１３ａによって、固定接点１１ｂから引き離されて、可動接点が固定接点１１ｂから離間した状態となる。 After that, when energization to the coil L of the electromagnet device 2 is completed (excitation of the coil L is completed), the movable iron core 16 is not attracted to the fixed iron core 17, so that the fixed iron is fixed by the spring force of the return spring S2. It moves in a direction away from the core 17 (downward direction in FIG. 4A). Therefore, the movable contact 12 is pulled away from the fixed contact 11b by the restricting portion 13a of the shaft 13, and the movable contact is separated from the fixed contact 11b.

なお、可動接点が固定接点１１ｂから引き離された際には、接点間にアークが発生することがあるが、このアークはカプセルヨーク４の磁場によって可動接触子１２の移動方向に直交する方向へ十分に引き伸ばされるとともに、封止容器１０内に封入されたガスによって冷却されるから、アーク電圧が急激に上昇し、このアーク電圧が接点間の電圧を上回った時点でアークが遮断される。つまり、本実施形態のリレーでは、カプセルヨーク４による磁気ブローと、封止容器１０内に封入したガスによる冷却とで、アーク対策が講じられている。これによりアークを短時間で遮断することができ、固定接点１１ｂおよび可動接点の消耗を抑制できる。 When the movable contact is separated from the fixed contact 11b, an arc may be generated between the contacts. This arc is sufficiently generated in the direction perpendicular to the moving direction of the movable contact 12 by the magnetic field of the capsule yoke 4. Since the arc voltage is rapidly increased and the arc voltage exceeds the voltage between the contacts, the arc is interrupted. That is, in the relay of the present embodiment, an arc countermeasure is taken by magnetic blow by the capsule yoke 4 and cooling by the gas sealed in the sealed container 10. Thereby, an arc can be interrupted | blocked in a short time, and consumption of the fixed contact 11b and a movable contact can be suppressed.

When the cover 31 is coupled to the body 30, the stepped portion 30 a of the body 30 is inserted inside the cover 31 as shown in FIGS. 3 and 4.

そして、電線３００を載置部５０に固定するにあたっては、固定部５１と載置部５０との間に電線３００を挿入すればよい。これによって、電線３００が載置部５０に固定される。このようして載置部５０に固定された電線３００は、接続片５０ｂに芯線３１０が半田付けされる。これによって電線３００はコイル給電用端子５に電気的に接続され、コイル給電用端子５と電磁石装置２のコイルＬとが電気的に接続される。そのため、一対のコイル給電用端子５の外側端子部５ａ間に所定の電圧を印加することによって、コイルＬに所定の電流を流すことができる。 In fixing the electric wire 300 to the placement unit 50, the electric wire 300 may be inserted between the fixing unit 51 and the placement unit 50. As a result, the electric wire 300 is fixed to the placement unit 50. Thus, the electric wire 300 fixed to the mounting part 50 has the core wire 310 soldered to the connection piece 50b. As a result, the electric wire 300 is electrically connected to the coil power supply terminal 5, and the coil power supply terminal 5 and the coil L of the electromagnet device 2 are electrically connected. Therefore, a predetermined current can be passed through the coil L by applying a predetermined voltage between the outer terminal portions 5 a of the pair of coil power supply terminals 5.

なお、電線３００を載置部５０に固定するにあたっては、例えば、突片５０ｄの基端部を曲げて、突片５０ｄを開口部５０ｃ内から外側に取り出した状態で、電線３００を、主部５０ａの幅方向（図５（ａ）における左右方向）に沿った方向で開口部５０ｃを横切るようにして載置部５０上に載置し、その後に、突片５０ｄを、先端部が電線３００における載置部５０側とは反対側の部位に当接するように曲げるようにしてもよい。つまり、電線３００を固定する際に、突片５０ｄを曲成して固定部５１を形成するようにしてもよいが、上述したように固定部５１を予め形成しておけば、電線３００の固定時に突片５０ｄを加工する必要がないから、電線３００の載置部５０への固定をより容易に行うことができる。 In fixing the electric wire 300 to the placing portion 50, for example, the base end portion of the protruding piece 50d is bent, and the electric wire 300 is connected to the main portion in a state where the protruding piece 50d is taken out from the opening 50c. 50a is placed on the placement part 50 so as to cross the opening 50c in the direction along the width direction (the left-right direction in FIG. 5A). You may make it bend so that it may contact | abut the site | part on the opposite side to the mounting part 50 side. That is, when the electric wire 300 is fixed, the protrusion 50d may be bent to form the fixing portion 51. However, if the fixing portion 51 is formed in advance as described above, the fixing of the electric wire 300 is performed. Since sometimes it is not necessary to process the protruding piece 50d, the electric wire 300 can be more easily fixed to the mounting portion 50.

ところで、載置部５０の主部５０ａの長さ方向他端部は、コイル給電用端子５をケース３に固定するための差込部５０ｅとして用いられる。この差込部５０ｅは、端部にいくにつれて厚みが徐々に薄くなる形に加工される。 By the way, the other end portion in the length direction of the main portion 50 a of the placement portion 50 is used as an insertion portion 50 e for fixing the coil feeding terminal 5 to the case 3. The insertion part 50e is processed into a shape in which the thickness gradually decreases toward the end.

上述したコイル給電用端子５は、金属板（例えば、金属のなかでも比較的導電性が良好な銅板）より打ち抜いた基礎部品を曲成することによって形成することができる。この際、開口部５０ｃおよび突片５０ｄは、載置部５０の主部５０ａにコ字形の孔を打ち抜き形成することによって得ることができる。そのため、本実施形態におけるコイル給電用端子５によれば、図１９に示すような従来例のコイル給電用端子２００に比べて、基礎部品のサイズを小さくできる。 The above-described coil feeding terminal 5 can be formed by bending a base part punched from a metal plate (for example, a copper plate having relatively good conductivity among metals). At this time, the opening 50c and the protruding piece 50d can be obtained by punching and forming a U-shaped hole in the main portion 50a of the mounting portion 50. Therefore, according to the coil power supply terminal 5 in the present embodiment, the size of the basic component can be reduced as compared with the conventional coil power supply terminal 200 as shown in FIG.

コイル給電用端子５は、ケース３を構成するボディ３０に取り付けられる。ここで、ボディ３０の内面には、図１に示すように、コイル給電用端子５を保持する平板状の保持部３２が突設される。保持部３２におけるボディ３０の開口面（図４（ａ）における上面）側の面には、コイル給電用端子５の差込部５０ｅが個別に差し込まれる２つの差込穴３２ａが開口する。そして、ボディ３０の内面における保持部３２の各差込穴３２ａとボディ３０の開口との間の部位には、スリット３３が形成される。各スリット３３には、コイル給電用端子５の外側端子部５ａが個別に挿通される。このスリット３３は、ボディ３０の長さ方向一端側において外部に解放される（ボディ３０の開口面に連通する）。したがって、スリット３３には、ボディ３０の長さ方向に沿った方向から外側端子部５ａを挿入できる。 The coil feeding terminal 5 is attached to the body 30 constituting the case 3. Here, on the inner surface of the body 30, as shown in FIG. 1, a flat plate-like holding portion 32 that holds the coil power feeding terminal 5 is projected. Two insertion holes 32a into which the insertion portions 50e of the coil power supply terminals 5 are individually inserted are opened on the surface of the holding portion 32 on the opening surface (the upper surface in FIG. 4A) side of the body 30. A slit 33 is formed in a portion between each insertion hole 32 a of the holding portion 32 and the opening of the body 30 on the inner surface of the body 30. The outer terminal portions 5 a of the coil power supply terminals 5 are individually inserted into the slits 33. The slit 33 is released to the outside at one end in the longitudinal direction of the body 30 (communication with the opening surface of the body 30). Therefore, the outer terminal portion 5 a can be inserted into the slit 33 from the direction along the length direction of the body 30.

本実施形態におけるボディ３０にコイル給電用端子５を取り付けるにあたっては、コイル給電用端子５をボディ３０の長さ方向に沿った方向においてスライド移動させ、差込部５０ｅを保持部３２の差込穴３２ａに、外側端子部５ａをスリット３３にそれぞれ挿入すればよい。このようにしてコイル給電用端子５を取り付けたボディ３０にカバー３１を結合した際には、カバー３１によってスリット３３の開口端が閉じられ、カバー３１と保持部３３との間でコイル給電用端子５が狭持され、ケース３に対してコイル給電用端子５が移動しないように固定される。 In attaching the coil power supply terminal 5 to the body 30 in this embodiment, the coil power supply terminal 5 is slid in the direction along the length direction of the body 30, and the insertion part 50 e is inserted into the insertion hole of the holding part 32. What is necessary is just to insert the outer side terminal part 5a in the slit 33 to 32a, respectively. Thus, when the cover 31 is coupled to the body 30 to which the coil power supply terminal 5 is attached, the opening end of the slit 33 is closed by the cover 31, and the coil power supply terminal is interposed between the cover 31 and the holding portion 33. 5 is clamped and fixed to the case 3 so that the coil feeding terminal 5 does not move.

ところで、上述したケース３には、内器ブロックＢＫに加えて、内器ブロックＢＫとケース３との間の衝突防止用に第１の緩衝部材６と、第２の緩衝部材７とが収納される。第１の緩衝部材６は、ボディ３０の内底面と内器ブロックＢＫとの間に介在される。この第１の緩衝部材６は、ゴムなどの弾性を有する樹脂材料により矩形板状に形成される。一方、第２の緩衝部材７は、カバー３１と封止容器１０の厚み方向他面側との間に介在される。この第２の緩衝部材７は、第１の緩衝部材６と同様にゴムなどの弾性を有する樹脂材料により形成された板状の主部７０を備える。主部７０には、固定端子１１の端子部１１ｃが貫挿される一対の円形状の孔部７０ａが開口する。この主部７０における孔部７０ａの周縁部には、カバー３１の端子孔３１ｂの内周面と端子部１１ｃの外周面との間に介在される円筒部７１が一体に突設される。 Incidentally, in the case 3 described above, in addition to the inner unit block BK, a first buffer member 6 and a second buffer member 7 are stored for preventing a collision between the inner unit block BK and the case 3. The The first buffer member 6 is interposed between the inner bottom surface of the body 30 and the inner unit block BK. The first buffer member 6 is formed in a rectangular plate shape from an elastic resin material such as rubber. On the other hand, the second buffer member 7 is interposed between the cover 31 and the other side in the thickness direction of the sealing container 10. Similar to the first buffer member 6, the second buffer member 7 includes a plate-like main portion 70 formed of a resin material having elasticity such as rubber. The main portion 70 has a pair of circular holes 70a through which the terminal portions 11c of the fixed terminals 11 are inserted. A cylindrical portion 71 interposed between the inner peripheral surface of the terminal hole 31b of the cover 31 and the outer peripheral surface of the terminal portion 11c is integrally protruded from the peripheral portion of the hole portion 70a in the main portion 70.

以上述べたように本実施形態のリレーは、上述した内器ブロックＢＫと、第１および第２の緩衝部材６，７とをケース３に収納することにより構成される。そして、本実施形態におけるケース３には、上述したように、電磁石装置２のコイルＬへの給電に使用されるコイル給電用端子５が取り付けられており、このコイル給電用端子５において電線３００が接続される内側端子部５ｂは、電線を載置する載置部５０と、載置部５０に電線を固定する固定部５１とを一体に備える。 As described above, the relay of this embodiment is configured by housing the above-described internal unit block BK and the first and second buffer members 6 and 7 in the case 3. As described above, the coil feeding terminal 5 used for feeding the coil L of the electromagnet device 2 is attached to the case 3 in the present embodiment, and the electric wire 300 is connected to the coil feeding terminal 5. The inner terminal portion 5 b to be connected is integrally provided with a placement portion 50 for placing the electric wire and a fixing portion 51 for fixing the electric wire to the placement portion 50.

このように本実施形態のリレーによれば、内側端子部５ｂは電線３００を載置部５０に固定する固定部５１を備えるから、コイルＬとの接続に使用する電線３００をコイル給電用端子５に容易に固定することができる。 As described above, according to the relay of this embodiment, the inner terminal portion 5b includes the fixing portion 51 that fixes the electric wire 300 to the placement portion 50. Therefore, the electric wire 300 used for connection to the coil L is used as the coil feeding terminal 5. Can be fixed easily.

しかも、固定部５１は、載置部３０に形成された開口部５０ｃの内周面に当該開口部５０ｃ内に収まる形で一体に突設された突片５０ｄより曲成される（つまり突片５０ｄが固定部５１の基礎となる）。そのため、コイル給電用端子５を、金属板より打ち抜いた基礎部品より曲成する場合、開口部５０ｃおよび突片５０ｄは、載置部５０の主部５０ａにコ字形の孔を打ち抜き形成することによって得ることができる。したがって、図１９に示す従来のように固定部２２２が載置部２２１の縁部に一体に突設された突片２２２ａより曲成されたものである場合に比べれば、コイル給電用端子の基礎部品のサイズを小さくできるから、基礎部品を金属板より打ち抜くために必要な面積が小さくなり、また突片５０ｄを形成するためだけに基礎部品のサイズを大きくする必要がないから、金属板の材料ロスも少なくでき、その結果、コイル給電用端子５の製造コストを低減でき、低コスト化を図ることができる。 In addition, the fixing portion 51 is bent by a projecting piece 50d integrally projecting on the inner peripheral surface of the opening 50c formed in the mounting portion 30 so as to be accommodated in the opening 50c (that is, the projecting piece). 50d is the basis of the fixing portion 51). Therefore, when the coil feeding terminal 5 is bent from a basic part punched out of a metal plate, the opening 50c and the projecting piece 50d are formed by punching a U-shaped hole in the main part 50a of the mounting part 50. Obtainable. Accordingly, as compared with the conventional case shown in FIG. 19, the fixed portion 222 is bent from the projecting piece 222 a integrally projecting on the edge of the mounting portion 221. Since the size of the part can be reduced, the area required for punching the base part from the metal plate is reduced, and it is not necessary to increase the size of the base part only to form the protruding piece 50d. Loss can also be reduced, and as a result, the manufacturing cost of the coil feeding terminal 5 can be reduced, and the cost can be reduced.

なお、本実施形態のリレーは、あくまでも本発明の一実施形態に過ぎないものであって、本発明の技術的範囲を本実施形態のものに限定する趣旨ではなく、本発明の趣旨を逸脱しない範囲での変更は当然に行える。例えば、本実施形態におけるケース３においては、ボディ３０にコイル給電用端子５を保持する保持部３２および外側端子部５ａをケース３外に突出させるためのスリット３３を設けているが、保持部３２やスリット３３はカバー３１側に設けられていてもよい。また、本実施形態におけるリレーの構造（特に内器ブロックＢＫの構造）は、図示例に限定されない。要は、電磁石装置が発生する電磁界によって、接点の開閉が可能な構成のものであれば、本発明の技術的思想を適用できる。この点は後述する実施形態２〜６においても同様である。 The relay of this embodiment is merely an embodiment of the present invention, and is not intended to limit the technical scope of the present invention to that of this embodiment, and does not depart from the spirit of the present invention. Naturally changes in range can be made. For example, in the case 3 in the present embodiment, the body 30 is provided with the holding portion 32 for holding the coil power feeding terminal 5 and the slit 33 for projecting the outer terminal portion 5a out of the case 3. The slit 33 may be provided on the cover 31 side. Further, the structure of the relay in this embodiment (particularly the structure of the internal unit block BK) is not limited to the illustrated example. In short, the technical idea of the present invention can be applied as long as the contact can be opened and closed by an electromagnetic field generated by the electromagnet device. This also applies to Embodiments 2 to 6 described later.

本実施形態のリレーは、ケース３の構成のみが実施形態１と異なる。なお、本実施形態のリレーにおけるケース３以外の構成は実施形態１と同様であるから、同様の構成については同一の符号を付して説明を省略する。 (Embodiment 2)
The relay of this embodiment is different from that of the first embodiment only in the configuration of case 3. In addition, since structures other than the case 3 in the relay of this embodiment are the same as that of Embodiment 1, the same code | symbol is attached | subjected about the same structure and description is abbreviate | omitted.

本実施形態におけるケース３のボディ３０には、図６（ａ），（ｂ）に示すように、長方形状の突出部３４が設けられる。突出部３４は、保持部３２における差込孔３２ａの開口縁部において、電線３００を挟んで固定部５１の連結部５１ｂに対向する位置に突設される。つまり、突出部３４は、電線３００を挟んで連結部５１ｂに対向配置される。したがって、コイル給電用端子５をケース３に取り付けた際には、電線３００は、突出部３４と連結部５１ｂとの間に収容される。 As shown in FIGS. 6A and 6B, the body 30 of the case 3 in the present embodiment is provided with a rectangular protrusion 34. The protruding portion 34 protrudes from the opening edge of the insertion hole 32 a in the holding portion 32 at a position facing the connecting portion 51 b of the fixing portion 51 with the electric wire 300 interposed therebetween. That is, the protruding portion 34 is disposed to face the connecting portion 51b with the electric wire 300 interposed therebetween. Therefore, when the coil power supply terminal 5 is attached to the case 3, the electric wire 300 is accommodated between the protruding portion 34 and the connecting portion 51b.

このように本実施形態のリレーのケース３は、電線３００を挟んで連結部５１ｂに対向配置され、連結部５１ｂとの間に電線３００を収容する突出部３４を備えるので、電線３００に外力がかけられた際（例えば電線３００が引っ張られた際）に、電線３００が爪部５１ａと載置部５０との隙間から抜け落ちてしまうことを防止することができるから、電線３００がコイル給電用端子５から外れてしまうことを抑制できる。 As described above, the relay case 3 of the present embodiment is disposed so as to face the connecting portion 51b with the electric wire 300 interposed therebetween, and includes the protruding portion 34 that accommodates the electric wire 300 between the connecting portion 51b. It is possible to prevent the electric wire 300 from falling out of the gap between the claw portion 51a and the placement portion 50 when it is hooked (for example, when the electric wire 300 is pulled). It can suppress that it remove | deviates from 5.

ところで、図６に示す例では、ボディ３０に突出部３４を設けているが、このような突出部３４は、図７（ａ），（ｂ）に示すように、カバー３１に設けるようにしてもよい。このような場合でも、同様の効果を得ることができる。なお、図７に示すコイル給電用端子５では、突片５０ｄを、開口部５０ｃにおける主部５０ａの長さ方向一端側の内周面ではなく、長さ方向他端側の内周面（つまり、図６に示す場合とは逆側の内周面）に突設してある。つまり、突出部３４は、ケース３を構成するボディ３０とカバー３１とのどちらに設けてもよい。また、突出部３４の形状は図示例に限定されず、本実施形態の趣旨を逸脱しない範囲で、好適な形状に変更することが可能である。 By the way, in the example shown in FIG. 6, the projecting portion 34 is provided on the body 30, but such a projecting portion 34 is provided on the cover 31 as shown in FIGS. 7 (a) and 7 (b). Also good. Even in such a case, a similar effect can be obtained. In the coil feeding terminal 5 shown in FIG. 7, the protruding piece 50d is not an inner peripheral surface on one end side in the length direction of the main portion 50a in the opening 50c but an inner peripheral surface on the other end side in the length direction (that is, The inner peripheral surface on the opposite side to the case shown in FIG. That is, the protruding portion 34 may be provided on either the body 30 or the cover 31 constituting the case 3. Moreover, the shape of the protrusion part 34 is not limited to the example of illustration, It is possible to change into a suitable shape in the range which does not deviate from the meaning of this embodiment.

（実施形態３）
本実施形態のリレーは、ケース３の構成のみが実施形態１と異なる。なお、本実施形態のリレーにおけるケース３以外の構成は実施形態１と同様であるから、同様の構成については同一の符号を付して説明を省略する。 (Embodiment 3)
The relay of this embodiment is different from that of the first embodiment only in the configuration of case 3. In addition, since structures other than the case 3 in the relay of this embodiment are the same as that of Embodiment 1, the same code | symbol is attached | subjected about the same structure and description is abbreviate | omitted.

本実施形態におけるケース３のボディ３０には、図８（ａ），（ｂ）に示すように、長方形状の突出部３４が設けられる。突出部３４は、保持部３２における差込孔３２ａの開口縁部において、電線３００を挟んで固定部５１の連結部５１ｂに対向する位置に突設される。つまり、突出部３４は、電線３００を挟んで連結部５１ｂに対向配置される。ここで、突出部３４の突出寸法は、コイル給電用端子５をケース３に取り付けた際に、電線３００と当接する程度の大きさとしている。つまり、上記実施形態２とは異なり、突出部３４は連結部５１ｂとの間で電線３００を狭持する形に形成される。 As shown in FIGS. 8A and 8B, the body 30 of the case 3 in the present embodiment is provided with a rectangular protrusion 34. The protruding portion 34 protrudes from the opening edge of the insertion hole 32 a in the holding portion 32 at a position facing the connecting portion 51 b of the fixing portion 51 with the electric wire 300 interposed therebetween. That is, the protruding portion 34 is disposed to face the connecting portion 51b with the electric wire 300 interposed therebetween. Here, the projecting dimension of the projecting portion 34 is set to such a size as to contact the electric wire 300 when the coil feeding terminal 5 is attached to the case 3. That is, unlike the second embodiment, the projecting portion 34 is formed to sandwich the electric wire 300 with the connecting portion 51b.

このように本実施形態のリレーのケース３は、電線３００を挟んで連結部５１ｂに対向配置され、連結部５１ｂとの間で電線３００を狭持する突出部３４を備えるので、電線３００に外力がかけられた際（例えば電線３００が引っ張られた際）に、電線３００が爪部５１ａと載置部５０との隙間から抜け落ちてしまうことを防止することができるから、電線３００がコイル給電用端子５から外れてしまうことを抑制できる。本実施形態では、電線３００が突出部３４と連結部５１ｂとの間に狭持されるから、電線３００がその長さ方向（図８（ａ）における左右方向）に引っ張られたときであっても、電線３００がコイル給電用端子５から外れ難くなる。つまり、電線３００の引っ張りに対する耐力を向上できる。 As described above, the relay case 3 of the present embodiment includes the protruding portion 34 that is disposed to face the connecting portion 51b with the electric wire 300 interposed therebetween, and holds the electric wire 300 between the connecting portion 51b. Is applied (for example, when the electric wire 300 is pulled), it is possible to prevent the electric wire 300 from falling out of the gap between the claw portion 51a and the mounting portion 50. It can suppress that it remove | deviates from the terminal 5. FIG. In this embodiment, since the electric wire 300 is pinched between the protrusion part 34 and the connection part 51b, when the electric wire 300 is pulled in the length direction (left-right direction in Fig.8 (a)), However, it becomes difficult for the electric wire 300 to come off from the coil feeding terminal 5. That is, the yield strength against pulling of the electric wire 300 can be improved.

ところで、図８に示す例では、ボディ３０に突出部３４を設けているが、このような突出部３４は、図９（ａ），（ｂ）に示すように、カバー３１に設けるようにしてもよい。このような場合でも、同様の効果を得ることができる。なお、図９に示すコイル給電用端子５では、突片５０ｄを、開口部５０ｃにおける主部５０ａの長さ方向一端側の内周面ではなく、長さ方向他端側の内周面（つまり、図６に示す場合とは逆側の内周面）に突設してある。つまり、突出部３４は、ケース３を構成するボディ３０とカバー３１とのどちらに設けてもよい。また、突出部３４の形状は図示例に限定されず、本実施形態の趣旨を逸脱しない範囲で、好適な形状に変更することが可能である。 By the way, in the example shown in FIG. 8, the projecting portion 34 is provided on the body 30, but such a projecting portion 34 is provided on the cover 31 as shown in FIGS. 9 (a) and 9 (b). Also good. Even in such a case, a similar effect can be obtained. In the coil feeding terminal 5 shown in FIG. 9, the protruding piece 50d is not the inner peripheral surface on one end side in the length direction of the main portion 50a in the opening 50c, but the inner peripheral surface on the other end side in the length direction (that is, The inner peripheral surface on the opposite side to the case shown in FIG. That is, the protruding portion 34 may be provided on either the body 30 or the cover 31 constituting the case 3. Moreover, the shape of the protrusion part 34 is not limited to the example of illustration, It is possible to change into a suitable shape in the range which does not deviate from the meaning of this embodiment.

（実施形態４）
本実施形態のリレーは、ケース３またはコイル給電用端子５の構成が実施形態１と異なる。なお、本実施形態のリレーにおけるケース３以外の構成は実施形態１と同様であるから、同様の構成については同一の符号を付して説明を省略する。 (Embodiment 4)
The relay of this embodiment is different from that of the first embodiment in the configuration of the case 3 or the coil feeding terminal 5. In addition, since structures other than the case 3 in the relay of this embodiment are the same as that of Embodiment 1, the same code | symbol is attached | subjected about the same structure and description is abbreviate | omitted.

本実施形態におけるケース３のボディ３０には、図１０（ａ）に示すように、実施形態２で述べたものと同様の突出部３４（本実施形態においては必要に応じて第１の突出部３４と称する）が設けられる。この第１の突出部３４Ａの長手方向（図１０（ａ）における左右方向）の両側それぞれには、棒状（例えば、角棒状）の突出部３４（本実施形態においては必要に応じて第２の突出部３４Ｂと称する）が設けられる。複数（図示例では２つ）の第２の突出部３４Ｂそれぞれは、電線３００における爪部５１ａ側とは反対側において電線３００に当接する形に形成される。また、複数の第２の突出部３４Ｂそれぞれは、電線３００を挟んで爪部５１ａと対向しない位置に形成される。つまり、載置部５０の厚み方向において、第２の突出部３４Ｂと爪部５１ａとが重複しないようにし、これによって、爪部５１ａと第２の突出部３４Ｂとで電線３００を挟まないようにしている。 As shown in FIG. 10A, the body 30 of the case 3 in the present embodiment has a protrusion 34 similar to that described in the second embodiment (in this embodiment, a first protrusion as necessary). 34). On both sides in the longitudinal direction (the left-right direction in FIG. 10A) of the first protrusion 34A, a rod-like (for example, a square bar-like) protrusion 34 (in the present embodiment, a second as necessary) A protrusion 34B). Each of the plurality (two in the illustrated example) of the second protrusions 34 B is formed to abut on the electric wire 300 on the side opposite to the claw portion 51 a side of the electric wire 300. Each of the plurality of second protrusions 34B is formed at a position that does not face the claw 51a with the electric wire 300 interposed therebetween. In other words, in the thickness direction of the placement portion 50, the second protrusion 34B and the claw portion 51a are not overlapped, thereby preventing the electric wire 300 from being sandwiched between the claw portion 51a and the second protrusion 34B. ing.

このように本実施形態のリレーのケース３は、電線３００における爪部５１ａ側とは反対側において電線３００に当接する複数（図示例では２つ）の第２の突出部３４Ｂを備え、第２の突出部３４Ｂそれぞれは、電線３００を挟んで爪部５１ａと対向しない位置に形成されているので、爪部５１ａと２個の第２の突出部３４Ｂとによって、電線３００が波形状に曲げられるから、電線３００がその長さ方向（図１０（ａ）における左右方向）に引っ張られたときであっても、電線３００がコイル給電用端子５から外れ難くなる。つまり、電線３００の引っ張りに対する耐力を向上できる。 As described above, the relay case 3 of the present embodiment includes a plurality of (two in the illustrated example) second projecting portions 34B that contact the electric wire 300 on the side opposite to the claw portion 51a side of the electric wire 300, and the second Each of the protruding portions 34B is formed at a position that does not face the claw portion 51a with the electric wire 300 interposed therebetween, so that the electric wire 300 is bent into a wave shape by the claw portion 51a and the two second protruding portions 34B. Therefore, even when the electric wire 300 is pulled in the length direction (the left-right direction in FIG. 10A), the electric wire 300 is unlikely to come off from the coil feeding terminal 5. That is, the yield strength against pulling of the electric wire 300 can be improved.

ところで、図１０（ａ）に示す例では、第１の突出部３４Ａに２つの第２の突出部３４Ｂを設けているが、第１の突出部３４Ａに設ける第２の突出部３４Ｂの数を１つにする代わりに、コイル給電用端子５に設ける固定部５１の数を増やしてもよい。例えば、図１０（ｂ）は、固定部５１を２つ設けた例を示している。なお、図１０（ｂ）に示す例では、２つの固定部５１それぞれの基礎となる突片５０ｄは同一の開口部５０ｃの内周面より突設される。また、第２の突出部３４は、第１の突出部３４の長手方向中央部に設けられ、これによって、いずれの固定部５１とも電線３００を挟んで対向しないようにしている。 In the example shown in FIG. 10A, two first protrusions 34B are provided on the first protrusion 34A, but the number of second protrusions 34B provided on the first protrusion 34A is the same. Instead of using one, the number of fixing portions 51 provided in the coil power feeding terminal 5 may be increased. For example, FIG. 10B shows an example in which two fixing portions 51 are provided. In the example shown in FIG. 10B, the protruding pieces 50d serving as the foundations of the two fixing portions 51 are provided so as to protrude from the inner peripheral surface of the same opening 50c. In addition, the second protrusion 34 is provided at the center in the longitudinal direction of the first protrusion 34, thereby preventing any fixed part 51 from being opposed to the electric wire 300.

このように固定部５１を複数設ければ、固定部５１が１つだけの場合よりも、電線３００に外力がかけられた際に、電線３００がコイル給電用端子５から外れてしまうことを抑制でき、特に、電線３００の引っ張りに対する耐力も向上できる。また、図１０（ｂ）に示す例では、第２の突出部３４Ｂと複数の固定部５１とによって、電線３００が波形状に曲げられるから、電線３００の引っ張りに対する耐力をさらに向上できる。 By providing a plurality of fixing portions 51 in this way, it is possible to prevent the electric wire 300 from being detached from the coil feeding terminal 5 when an external force is applied to the electric wire 300, as compared to the case where there is only one fixing portion 51. In particular, the resistance to pulling of the electric wire 300 can also be improved. Further, in the example shown in FIG. 10B, since the electric wire 300 is bent into a wave shape by the second projecting portion 34B and the plurality of fixing portions 51, it is possible to further improve the resistance to pulling of the electric wire 300.

また、第２の突出部３４Ｂと固定部５１とをそれぞれ複数設けるようにしてもよい。例えば、図１０（ｃ）は、図１０（ｂ）に示す例において、第２の突出部３４Ｂの数を３つに増やした例を示している。つまり、図１０（ｃ）に示す例では、第１の突出部３４Ａの長手方向中央部および両側それぞれに、第２の突出部３４Ｂが形成されている。したがって、図１０（ｃ）に示す例では、コイル給電用端子５に固定部５１が複数（図示例では２つ）備えられ、ケース３に第２の突出部３４Ｂが複数（図示例では３つ）備えられ、固定部５１と第２の突出部３４Ｂとは、電線３００の長さ方向に沿って交互に並んでいる。この場合においては、複数の固定部５１と、複数の第２の突出部３４Ｂとによって、図１０（ａ），（ｂ）に示す場合よりも、波形状に曲げられた電線３００における節や腹の数を増やすことができるから、電線３００の引っ張りに対する耐力をさらに向上できる。なお、第１の突出部３４Ａは、連結部５１ｂとの間に電線３００を収容するものではなく、実施形態３で述べたように、連結部５１ｂとの間で電線３００を狭持するものであってもよい。 A plurality of second projecting portions 34B and a plurality of fixing portions 51 may be provided. For example, FIG.10 (c) has shown the example which increased the number of the 2nd protrusion parts 34B to three in the example shown in FIG.10 (b). That is, in the example shown in FIG. 10C, the second protrusions 34B are formed at the longitudinal center part and both sides of the first protrusions 34A. Accordingly, in the example shown in FIG. 10C, the coil feeding terminal 5 is provided with a plurality of fixing portions 51 (two in the illustrated example), and the case 3 has a plurality of second projecting portions 34B (three in the illustrated example). ) And the fixed portions 51 and the second protruding portions 34B are alternately arranged along the length direction of the electric wire 300. In this case, the nodes and bellies of the electric wire 300 bent into a wave shape are formed by the plurality of fixing portions 51 and the plurality of second projecting portions 34B as compared with the case shown in FIGS. 10 (a) and 10 (b). Since the number of wires can be increased, it is possible to further improve the resistance to pulling of the electric wire 300. In addition, 34 A of 1st protrusions do not accommodate the electric wire 300 between the connection parts 51b, but hold the electric wire 300 between the connection parts 51b as described in Embodiment 3. There may be.

ところで、図１０（ａ）〜（ｃ）に示す例では、ボディ３０に突出部３４（第１の突出部３４Ａおよび第２の突出部３４Ｂ）を設けているが、このような突出部３４は、図１１（ａ）〜（ｃ）に示すように、カバー３１に設けるようにしてもよい。このような場合でも、同様の効果を得ることができる。なお、図１１（ａ）〜（ｃ）に示すコイル給電用端子５では、突片５０ｄを、開口部５０ｃにおける主部５０ａの長さ方向一端側の内周面ではなく、長さ方向他端側の内周面（つまり、図１０（ａ）〜（ｃ）に示す場合とは逆側の内周面）に突設してある。つまり、突出部３４は、ケース３を構成するボディ３０とカバー３１とのどちらに設けてもよい。また、突出部３４の形状は図示例に限定されず、本実施形態の趣旨を逸脱しない範囲で、好適な形状に変更することが可能である。 By the way, in the example shown to Fig.10 (a)-(c), although the protrusion part 34 (1st protrusion part 34A and 2nd protrusion part 34B) is provided in the body 30, such protrusion part 34 is provided. 11 (a) to 11 (c), the cover 31 may be provided. Even in such a case, a similar effect can be obtained. In addition, in the coil feeding terminal 5 shown in FIGS. 11A to 11C, the projecting piece 50d is not the inner peripheral surface of one end side in the length direction of the main portion 50a in the opening 50c, but the other end in the length direction. It protrudes on the inner peripheral surface on the side (that is, the inner peripheral surface on the opposite side to the case shown in FIGS. 10A to 10C). That is, the protruding portion 34 may be provided on either the body 30 or the cover 31 constituting the case 3. Moreover, the shape of the protrusion part 34 is not limited to the example of illustration, It is possible to change into a suitable shape in the range which does not deviate from the meaning of this embodiment.

（実施形態５）
本実施形態のリレーは、ケース３またはコイル給電用端子５の構成が実施形態１と異なる。なお、本実施形態のリレーにおけるケース３以外の構成は実施形態１と同様であるから、同様の構成については同一の符号を付して説明を省略する。 (Embodiment 5)
The relay of this embodiment is different from that of the first embodiment in the configuration of the case 3 or the coil feeding terminal 5. In addition, since structures other than the case 3 in the relay of this embodiment are the same as that of Embodiment 1, the same code | symbol is attached | subjected about the same structure and description is abbreviate | omitted.

本実施形態におけるコイル給電用端子５は、図１２（ａ）に示すように、複数（図示例では２つ）の固定部５１を備える。図１２に示す例では、２つの固定部５１それぞれの基礎となる突片５０ｄは同一の開口部５０ｃの内周面より突設される。 As shown in FIG. 12A, the coil power supply terminal 5 in the present embodiment includes a plurality (two in the illustrated example) of fixing portions 51. In the example shown in FIG. 12, the projecting piece 50 d serving as the basis of each of the two fixing portions 51 is provided so as to project from the inner peripheral surface of the same opening 50 c.

本実施形態におけるケース３のボディ３０には、図１２（ａ），（ｂ）に示すように、矩形状の突出部３４が設けられる。突出部３４は、２つの固定部５１の間に位置する形で保持部３２における差込孔３２ａの開口縁部に突設される。この突出部３４には、電線３００が突出部３４の幅方向（図１２（ａ）における左右方向）に沿った方向に貫挿される収容凹所３４ａが形成される。収容凹所３４ａは、突出部３４の先端側（固定部５１側）において外部に開放される。また、収容凹所３４ａの底面は、保持部３２の差込孔３２ａに連通する。そのため、電線３００を固定したコイル給電用端子５をボディ３０に取り付けることによって、電線３００が収容凹所３４ａ内に収容される。ここで、収容凹所３４ａの内面形状は、固定部５１により電線３００を内面に押し当てることが可能な形に形成される。また、収容凹所３４ａは開口（開放）側（図１２（ｂ）における上側）が拡開する（開口側にいくにつれて内部空間が広がる）形に形成される。これによって、電線３００を収容凹所３４ａ内に収容し易くしている。 As shown in FIGS. 12A and 12B, the body 30 of the case 3 in the present embodiment is provided with a rectangular protrusion 34. The projecting portion 34 projects from the opening edge of the insertion hole 32 a in the holding portion 32 so as to be positioned between the two fixing portions 51. The protruding portion 34 is formed with a housing recess 34a through which the electric wire 300 is inserted in a direction along the width direction of the protruding portion 34 (the left-right direction in FIG. 12A). The housing recess 34a is opened to the outside on the distal end side (fixed portion 51 side) of the projecting portion 34. Further, the bottom surface of the accommodation recess 34 a communicates with the insertion hole 32 a of the holding portion 32. Therefore, by attaching the coil feeding terminal 5 to which the electric wire 300 is fixed to the body 30, the electric wire 300 is accommodated in the accommodating recess 34a. Here, the inner surface shape of the accommodation recess 34 a is formed in a shape that allows the electric wire 300 to be pressed against the inner surface by the fixing portion 51. Further, the accommodation recess 34a is formed in a shape in which the opening (opening) side (the upper side in FIG. 12B) is expanded (the inner space is expanded toward the opening side). Thereby, the electric wire 300 is easily accommodated in the accommodating recess 34a.

上述した本実施形態のリレーにおいて、コイル給電用端子５をケース３に固定した状態では、電線３００は、収容凹所３４ａ内に位置する。そして、電線３００が収容凹所３４ａから外側に出ることは、固定部５１の連結部５１ｂによって阻まれることになる。 In the relay according to the present embodiment described above, in a state where the coil power supply terminal 5 is fixed to the case 3, the electric wire 300 is located in the housing recess 34a. And it will be blocked | interrupted by the connection part 51b of the fixing | fixed part 51 that the electric wire 300 goes outside from the accommodation recess 34a.

以上述べたように本実施形態のリレーのケース３は、固定部５１により電線３００が内面に押し当てられた形で電線３０を収容する収容凹所３４ａを有した突出部３４を備えるので、電線３００は固定部５１により収容凹所３４ａの内面に圧接された状態で収容凹所３４ａ内に収容されるから、電線３００に外力がかけられた際（例えば電線３００が引っ張られた際）に、電線３００が爪部５１ａと載置部５０との隙間から抜け落ちてしまうことを防止することができ、電線３００がコイル給電用端子５から外れてしまうことを抑制できる。特に、本実施形態では、電線３００が収容凹所３４ａの内面に圧接されるから、電線３００と突出部３４との間の摩擦力が増大し、電線３００がその長さ方向（図１２（ａ）における左右方向）に引っ張られたときであっても、電線３００がコイル給電用端子５から外れ難くなる。つまり、電線３００の引っ張りに対する耐力を向上できる。 As described above, the case 3 of the relay according to the present embodiment includes the protruding portion 34 having the housing recess 34a for housing the electric wire 30 in a form in which the electric wire 300 is pressed against the inner surface by the fixing portion 51. Since 300 is housed in the housing recess 34a in a state of being pressed against the inner surface of the housing recess 34a by the fixing portion 51, when an external force is applied to the wire 300 (for example, when the wire 300 is pulled), It is possible to prevent the electric wire 300 from falling out of the gap between the claw portion 51a and the placement portion 50, and it is possible to suppress the electric wire 300 from being detached from the coil feeding terminal 5. In particular, in this embodiment, since the electric wire 300 is press-contacted to the inner surface of the housing recess 34a, the frictional force between the electric wire 300 and the protruding portion 34 increases, and the electric wire 300 has its length direction (FIG. 12 (a Even when the wire 300 is pulled in the left-right direction in FIG. That is, the yield strength against pulling of the electric wire 300 can be improved.

ところで、図１２に示す例では、ボディ３０に突出部３４を設けているが、このような突出部３４は、図１３（ａ），（ｂ）に示すように、カバー３１に設けるようにしてもよい。図１３に示す例では、突出部３４は、カバー３１に設けられた長尺板状の突片３５の先端部に設けられている。 By the way, in the example shown in FIG. 12, the projecting portion 34 is provided on the body 30, but such a projecting portion 34 is provided on the cover 31 as shown in FIGS. 13 (a) and 13 (b). Also good. In the example shown in FIG. 13, the protruding portion 34 is provided at the tip of a long plate-like protruding piece 35 provided on the cover 31.

このような場合でも、同様の効果を得ることができる。なお、図１３に示すコイル給電用端子５では、突片５０ｄを、開口部５０ｃにおける主部５０ａの長さ方向一端側の内周面ではなく、長さ方向他端側の内周面（つまり、図１２に示す場合とは逆側の内周面）に突設してある。つまり、本実施形態における突出部３４は、ケース３を構成するボディ３０とカバー３１とのどちらに設けてもよい。 Even in such a case, a similar effect can be obtained. In the coil feeding terminal 5 shown in FIG. 13, the protruding piece 50d is not an inner peripheral surface on one end side in the length direction of the main portion 50a in the opening 50c but an inner peripheral surface on the other end side in the length direction (that is, The inner peripheral surface on the opposite side to the case shown in FIG. That is, the protruding portion 34 in the present embodiment may be provided on either the body 30 or the cover 31 constituting the case 3.

なお、図１２，１３に示す例では、固定部５１が２つ設けられているが、固定部５１は必ずしも複数設ける必要はなく、１つであってもよい。また、突出部３４の数も１つに限らず、複数設けるようにしてもよい。また、突出部３４の形状は図示例に限定されず、本実施形態の趣旨を逸脱しない範囲で、好適な形状に変更することが可能である。 In the example shown in FIGS. 12 and 13, two fixing portions 51 are provided. However, a plurality of fixing portions 51 are not necessarily provided, and one fixing portion 51 may be provided. Further, the number of protrusions 34 is not limited to one, and a plurality of protrusions 34 may be provided. Moreover, the shape of the protrusion part 34 is not limited to the example of illustration, It is possible to change into a suitable shape in the range which does not deviate from the meaning of this embodiment.

（実施形態６）
本実施形態のリレーは、ケース３の構成のみが実施形態１と異なる。なお、本実施形態のリレーにおけるケース３以外の構成は実施形態１と同様であるから、同様の構成については同一の符号を付して説明を省略する。 (Embodiment 6)
The relay of this embodiment is different from that of the first embodiment only in the configuration of case 3. In addition, since structures other than the case 3 in the relay of this embodiment are the same as that of Embodiment 1, the same code | symbol is attached | subjected about the same structure and description is abbreviate | omitted.

本実施形態におけるケース３のボディ３０には、図１４に示すように、長方形状の突出部３４が設けられる。突出部３４は、図１５（ａ），（ｂ）に示すように、保持部３２における差込孔３２ａの開口縁部に、固定部５１の爪部５１ａにおける電線３００側とは反対側（図１５（ｂ）における右側）に位置するように突設される。突出部３４における爪部５１ａとの対向面（図１５（ｂ）における左面）は、突出部３４の基端部側（図１５（ｂ）における下側）ほど、コイル給電用端子５の載置部５０との距離が短くなるように傾斜したテーパ面に形成される。 The body 30 of the case 3 in the present embodiment is provided with a rectangular protrusion 34 as shown in FIG. As shown in FIGS. 15A and 15B, the protruding portion 34 is formed on the opening edge of the insertion hole 32 a in the holding portion 32 on the side opposite to the wire 300 side in the claw portion 51 a of the fixing portion 51 (see FIG. 15 (b) on the right side). The surface of the protruding portion 34 facing the claw portion 51a (the left surface in FIG. 15B) is closer to the base end portion of the protruding portion 34 (lower side in FIG. 15B), and the coil feeding terminal 5 is placed thereon. It is formed in the taper surface which inclined so that the distance with the part 50 might become short.

したがって、コイル給電用端子５をケース３に取り付ける際には、図１５（ａ），（ｂ）に示すように、差込孔３２ａ内への載置部５０の挿入量が増えるにつれて、爪部５１ａが載置部５０側へ押圧される。つまり、突出部３４は、固定部５１を爪部５１ａと載置部５０との距離が短くなるように変形させる。 Therefore, when the coil feeding terminal 5 is attached to the case 3, as shown in FIGS. 15A and 15B, as the insertion amount of the mounting portion 50 into the insertion hole 32a increases, the claw portion 51a is pressed to the mounting part 50 side. That is, the protruding portion 34 deforms the fixing portion 51 so that the distance between the claw portion 51a and the placement portion 50 is shortened.

このように本実施形態のリレーのケース３は、実施形態１と同様の効果に加え、コイル給電用端子５をケース３に取り付けた際に、爪部５１ａを載置部５０側へ押圧する突出部３４を備えているので、固定部５１によってより強固に電線３００を載置部５０に固定することが可能になる。また、突出部３４が爪部５１ａに当接するので、電線３００が強く引っ張られて爪部５１ａが載置部５０から離間するように固定部５１が変形しようとしても、このような固定部５１の変形を防止することができる。 As described above, in addition to the same effects as those of the first embodiment, the relay case 3 of the present embodiment has a protrusion that presses the claw portion 51a toward the mounting portion 50 when the coil feeding terminal 5 is attached to the case 3. Since the part 34 is provided, the electric wire 300 can be more firmly fixed to the mounting part 50 by the fixing part 51. Further, since the protruding portion 34 contacts the claw portion 51a, even if the fixing portion 51 is deformed so that the electric wire 300 is pulled strongly and the claw portion 51a is separated from the placement portion 50, Deformation can be prevented.

ところで、図１４および図１５に示す例では、ボディ３０に突出部３４を設けているが、このような突出部３４は、図１６および図１７に示すように、カバー３１に設けるようにしてもよい。図１６および図１７に示す例では、突出部３４は、カバー３１に設けられた長尺板状の突片３５の先端部に設けられている。 By the way, in the example shown in FIGS. 14 and 15, the projecting portion 34 is provided on the body 30, but such a projecting portion 34 may be provided on the cover 31 as shown in FIGS. 16 and 17. Good. In the example shown in FIGS. 16 and 17, the protrusion 34 is provided at the tip of a long plate-like protrusion 35 provided on the cover 31.

このような場合でも、同様の効果を得ることができる。なお、図１６に示すコイル給電用端子５では、突片５０ｄを、開口部５０ｃにおける主部５０ａの長さ方向一端側の内周面ではなく、長さ方向他端側の内周面（つまり、図１４に示す場合とは逆側の内周面）に突設してある。つまり、突出部３４は、ケース３を構成するボディ３０とカバー３１とのどちらに設けてもよい。 Even in such a case, a similar effect can be obtained. In the coil feeding terminal 5 shown in FIG. 16, the protruding piece 50d is not an inner peripheral surface on one end side in the length direction of the main portion 50a in the opening 50c but an inner peripheral surface on the other end side in the length direction (that is, , And protrudes on the inner peripheral surface opposite to the case shown in FIG. That is, the protruding portion 34 may be provided on either the body 30 or the cover 31 constituting the case 3.

なお、図１４〜１７に示す例では、固定部５１を１つだけ備えているが、固定部５１は複数備えていてもよい。また、突出部３４の数も１つに限らず、複数設けるようにしてもよい。また、突出部３４の形状は図示例に限定されず、本実施形態の趣旨を逸脱しない範囲で、好適な形状に変更することが可能である。 In addition, in the example shown to FIGS. 14-17, although only the one fixing | fixed part 51 is provided, the fixing | fixed part 51 may be provided with two or more. Further, the number of protrusions 34 is not limited to one, and a plurality of protrusions 34 may be provided. Moreover, the shape of the protrusion part 34 is not limited to the example of illustration, It is possible to change into a suitable shape in the range which does not deviate from the meaning of this embodiment.
