本発明は、ソレノイドに関し、特にケースに対してコネクタを一体的に設けた構成を有するソレノイドに関する。 The present invention relates to a solenoid, and more particularly to a solenoid having a configuration in which a connector is provided integrally with a case.

ソレノイドにおいては、ケースに対してコネクタを一体的に設けている、いわゆるダイレクトカプラ型のものがある。ダイレクトカプラ型のソレノイドは、ケースとは別体のコネクタを設けているソレノイドよりも配置に必要となるスペースが小さくなるという利点がある。 There is a so-called direct coupler type solenoid in which a connector is provided integrally with a case. The direct coupler type solenoid has an advantage that a space required for arrangement is smaller than a solenoid provided with a connector separate from the case.

図１４は、特開２００５−０９８３１０公報において開示されている発明である。ソレノイドバルブ１０１は、バルブ部１０２と直動型のソレノイド部１１５とから構成されている。バルブ部１０２は、スプールバルブであり、スプール１０３が摺動可能に設けられており、スプール１０３のストローク長に応じて開弁量が変化する。ソレノイド部１１５は、ケース１１０の内部に設けられたボビン１０４、ボビン１０４に巻回して設けられると共に励磁手段であるコイル１０５、ケース１１０内部のバルブ部１０２側に設けられた固定磁極１０６、ケース１１０内部のコネクタ１１２側に設けられた補助磁極１０７、コイル１０５への通電時に固定磁極１０６に吸引されて摺動する可動磁極１０８、可動磁極１０８に連動して摺動すると共にスプール１０３を摺動させるロッド１０９、可動磁極１０８、摺動を案内するスリーブ１１１、並びに、コイル１０５の電気的接続を確保するためのコネクタ１１２及びその端子１１３を備えている。そして、コイル１０５に通電することによってコイル１０５が磁界を発生し、固定磁極１０６、ケース１１０、補助磁極１０７、可動磁極１０８及び固定磁極１０６を巡る磁気回路が生成され、可動磁極１０８が固定磁極１０６に吸引される。また、実装対象となる装置には、固定部材１１４をネジ止めすることによって固定される。 FIG. 14 is an invention disclosed in Japanese Patent Laid-Open No. 2005-098310. The solenoid valve 101 includes a valve portion 102 and a direct acting solenoid portion 115. The valve portion 102 is a spool valve, and the spool 103 is slidably provided, and the valve opening amount changes according to the stroke length of the spool 103. The solenoid unit 115 is provided in the bobbin 104 provided inside the case 110, wound around the bobbin 104 and provided with the coil 105 serving as an excitation unit, the fixed magnetic pole 106 provided on the valve unit 102 inside the case 110, and the case 110. An auxiliary magnetic pole 107 provided on the internal connector 112 side, a movable magnetic pole 108 that is attracted and slid by the fixed magnetic pole 106 when the coil 105 is energized, and slides in conjunction with the movable magnetic pole 108 and slides the spool 103. A rod 109, a movable magnetic pole 108, a sleeve 111 for guiding sliding, and a connector 112 for securing an electrical connection of the coil 105 and its terminal 113 are provided. When the coil 105 is energized, the coil 105 generates a magnetic field, and a magnetic circuit is generated around the fixed magnetic pole 106, the case 110, the auxiliary magnetic pole 107, the movable magnetic pole 108, and the fixed magnetic pole 106. Sucked into. Moreover, it fixes to the apparatus used as mounting object by screwing the fixing member 114. FIG.

以上のように、コネクタをケースに対して一体的に設ける構成を採用する場合、実装対象となる装置の部品の実装密度が高いことが多く、コネクタの形状や、ソレノイドの中心軸方向における長さ、端子の配置が厳密に決定されていることが多い。よって、例えば、実装対象となる装置が中級品から高級品まで複数種存在する場合や、実装対象となる装置を設計変更する場合には、コネクタの形状や、ソレノイドの中心軸方向における長さ、配置も変更を要することになる。図１４のコネクタ１１２のように、この種のコネクタは形状が複雑であり、端子材料等の加工コストは特に大きい。このように、複数種の装置を製造する場合や設計変更がある場合などでコネクタの形状や大きさ、端子の配置に変更があると、コイルを構成するコイルワイヤの端部と、端子又は端子に接続されたリード線との接続作業における手順等の変更が必要になる。コイルを構成するコイルワイヤの端部と、端子又は端子に接続されたリード線との接続作業は、小さな対象物をヒュージングするなどの習熟を要する作業が多いので、作業手順等の変更は製造コスト増大の大きな要因になる。当然作業者の負担も増大することになる。 As described above, when adopting a configuration in which the connector is provided integrally with the case, the mounting density of the parts of the device to be mounted is often high, and the shape of the connector and the length in the central axis direction of the solenoid In many cases, the arrangement of terminals is strictly determined. Therefore, for example, when there are multiple types of devices to be mounted, ranging from intermediate products to luxury products, or when changing the device to be mounted, the shape of the connector, the length of the solenoid in the central axis direction, The arrangement will also need to be changed. Like the connector 112 of FIG. 14, this type of connector has a complicated shape, and the processing cost of the terminal material and the like is particularly high. As described above, when there are changes in the shape and size of the connector and the arrangement of the terminals, such as when a plurality of types of devices are manufactured or there is a design change, the ends of the coil wires constituting the coil and the terminals or terminals It is necessary to change the procedure in the connection work with the lead wire connected to the cable. The connection work between the end of the coil wire that constitutes the coil and the terminal or lead wire connected to the terminal is often required to learn such as fusing a small object. It becomes a big factor of cost increase. Naturally, the burden on the worker will also increase.

The fixing opening 76a and the fixing opening 76b are for fixing to an external device on which the solenoid 10 is mounted.

また、図１及び図２に示すように、ソレノイド１０は、固定用板材７６側に開口しているスリーブ７２の小径部７４の内部に可動磁極６２が設けられており、さらに固定磁極６０の大部分がスリーブ７２の大径部７３の内部に挿入された状態で設けられている。スリーブ７２は、可動磁極６２の摺動を案内する。可動磁極６２には、その中心軸に沿ってシャフト保持用貫通孔６３が形成されている。スリーブ７２は、前面部７５を設けて袋状に形成されており、シャフト摺動用貫通孔６１から作動油などが浸入して来ても、コイル７０や、第１の端子部２４及び第２の端子部３４まで侵入することはない。 As shown in FIGS. 1 and 2, the solenoid 10 is provided with a movable magnetic pole 62 inside a small diameter portion 74 of a sleeve 72 opened to the fixing plate member 76 side. The portion is provided in a state of being inserted into the large diameter portion 73 of the sleeve 72. The sleeve 72 guides the sliding of the movable magnetic pole 62. A shaft holding through hole 63 is formed in the movable magnetic pole 62 along the central axis. The sleeve 72 is formed in a bag shape with a front surface portion 75, and even if hydraulic oil or the like enters from the shaft sliding through-hole 61, the sleeve 70, the first terminal portion 24, and the second terminal 72 are formed. The terminal part 34 does not enter.

可動磁極６２のシャフト保持用貫通孔６３には、シャフト６４が嵌合されている可動磁極６２が固定磁極６０に吸引されて摺動すると、シャフト６４も一体的に摺動する。さらに、固定磁極６０にも、その中心軸に沿ってシャフト摺動用貫通孔６１が形成されている。シャフト摺動用貫通孔６１には、シャフト６４の先端側が摺動可能な状態で挿入されており、可動磁極６２の摺動に連動してシャフト６４の先端部がシャフト摺動用貫通孔６１から突出するように構成されている。突出したシャフト６４の先端部は、例えばスプール弁のスプールなどの対象物を押圧して可動磁極６２と同じ方向に作動させる。また、通電を停止すると、図示していない外部装置からの押圧力でシャフト６４が押し戻され、可動磁極６２が元の待機位置に復帰する。なお、ソレノイド１０の内部に可動磁極６２の復帰用スプリングを設けてもよい。 When the movable magnetic pole 62 fitted with the shaft 64 is attracted to and slides in the shaft holding through hole 63 of the movable magnetic pole 62, the shaft 64 also slides integrally. Further, a shaft sliding through hole 61 is formed in the fixed magnetic pole 60 along the central axis. The shaft sliding through hole 61 is inserted in a state where the tip end of the shaft 64 is slidable, and the tip end portion of the shaft 64 projects from the shaft sliding through hole 61 in conjunction with the sliding of the movable magnetic pole 62. It is configured as follows. The protruding tip portion of the shaft 64 presses an object such as a spool of a spool valve to operate in the same direction as the movable magnetic pole 62. When the energization is stopped, the shaft 64 is pushed back by a pressing force from an external device (not shown), and the movable magnetic pole 62 returns to the original standby position. A return spring for the movable magnetic pole 62 may be provided inside the solenoid 10.

さらに、補助磁極６５の鍔状部６６がケース６８のコネクタ１１が設けられる側の開口部から圧入され、ケース６８に対して嵌合されている。また、補助磁極６５の円筒状部６７がスリーブ７２の小径部７４を囲むように設けられている。また、ケース６８の内部には、補助磁極６５に加えてコイル７０が設けられている。コイル７０は、ボビン５０の巻胴部にコイルワイヤを巻回して設けられている。またコイル７０は、図２、図３及び図５に示すように、第１の端子接続部材２０及び第２の端子接続部材３０を介してコネクタ１１の一部である第１の端子部２４の外部突出部２９及び第２の端子部の外部突出部３９に電気的に接続可能である。よって、外部突出部２９及び外部突出部３９に外部のコネクタを電気的に接続することによって、コイルに対して電流を供給することが可能である。コイル７０に電流が供給されると、可動磁極６２、固定磁極６０、ケース６８及び補助磁極６５を巡る磁気回路が生成されて可動磁極６２が固定磁極６０に吸引され、固定磁極６０側に摺動する。なお、ソレノイド１０に対して、弁体や弁座、リンク機構が一体的に設けられていてもよい。 Further, the hook-like portion 66 of the auxiliary magnetic pole 65 is press-fitted from the opening of the case 68 on the side where the connector 11 is provided, and is fitted to the case 68. A cylindrical portion 67 of the auxiliary magnetic pole 65 is provided so as to surround the small diameter portion 74 of the sleeve 72. In addition to the auxiliary magnetic pole 65, a coil 70 is provided inside the case 68. The coil 70 is provided by winding a coil wire around the winding body of the bobbin 50. Further, as shown in FIGS. 2, 3, and 5, the coil 70 has a first terminal portion 24 that is a part of the connector 11 via the first terminal connecting member 20 and the second terminal connecting member 30. It can be electrically connected to the external protrusion 29 and the external protrusion 39 of the second terminal portion. Therefore, it is possible to supply current to the coil by electrically connecting an external connector to the external protrusion 29 and the external protrusion 39. When a current is supplied to the coil 70, a magnetic circuit is generated around the movable magnetic pole 62, the fixed magnetic pole 60, the case 68, and the auxiliary magnetic pole 65, and the movable magnetic pole 62 is attracted to the fixed magnetic pole 60 and slides toward the fixed magnetic pole 60 side. To do. Note that a valve body, a valve seat, and a link mechanism may be provided integrally with the solenoid 10.

コネクタ１１は、図７に示すように、本体部４０、及び、一対の端子部である第１の端子部２４と第２の端子部３４とを備えている。コネクタ１１の本体部４０は、図１１及び図１２に示すように、円板状部４１及び矩形筒状部４２を備えている。円板状部４１は、ケース６８のエンドキャップとしての機能と、外部装置のコネクタと接続するために、第１の端子部２４及び第２の端子部３４を所定状態に保持する機能を併せ持っている。すなわち、円板状部４１は、ケース６８の開口部から内周面の段差部に当接するところまで軽く圧入し、ケース６８の端部を図１の曲げ加工部６９のように曲げ加工することによって、ケース６８に強固に固定される。円板状部４１の下側環状突出部４１ａは、ケース６８の内周面の段差部に当接する部分である。また、上側環状突出部４１ｂは曲げ加工部６９に当接する部分となるので、外周側が曲げ加工部６９に対応した形状に形成されている。下側環状突出部４１ａと上側環状突出部４１ｂの間の環状溝部４３は、Ｏリングや角リングなどのシール材を設ける際に、当該シール材を収納する空間となる。 As shown in FIG. 7, the connector 11 includes a main body portion 40 and a first terminal portion 24 and a second terminal portion 34 which are a pair of terminal portions. As shown in FIGS. 11 and 12, the main body portion 40 of the connector 11 includes a disk-shaped portion 41 and a rectangular tubular portion 42. The disc-like portion 41 has both a function as an end cap of the case 68 and a function of holding the first terminal portion 24 and the second terminal portion 34 in a predetermined state in order to connect to the connector of the external device. Yes. That is, the disc-like portion 41 is lightly press-fitted from the opening of the case 68 to a position where it comes into contact with the stepped portion on the inner peripheral surface, and the end of the case 68 is bent like the bending portion 69 in FIG. Thus, the case 68 is firmly fixed. The lower annular protrusion 41 a of the disk-like part 41 is a part that abuts on the stepped part of the inner peripheral surface of the case 68. Further, since the upper annular projecting portion 41 b is a portion that comes into contact with the bending portion 69, the outer peripheral side is formed in a shape corresponding to the bending portion 69. The annular groove 43 between the lower annular protrusion 41a and the upper annular protrusion 41b serves as a space for storing the sealing material when a sealing material such as an O-ring or a square ring is provided.

本体部４０の矩形筒状部４２は、外部装置等のコネクタと直接に結合される部分であり、円板状部４１の外側面からケース６８の中心軸に沿って延びるように形成されている。なお、矩形筒状部４２は円板状部４１に対して偏心している部位に配置されているが、矩形筒状部４２の配置はソレノイド１０を実装する装置の状況に応じて、例えば中心に配置するなど適宜変更してよい。同様に、矩形筒状部４２の中心軸方向の長さや径、外形についても、実装する装置に応じて適宜変更してよい。くわえて、矩形筒状部４２と円板状部４１とには、ケース６８の中心軸に沿って延びる端子保持用貫通孔４８ａ及び端子保持用貫通孔４８ｂが形成されている。端子保持用貫通孔４８ａと端子保持用貫通孔４８ｂとは、第１の端子部２４の外部突出部２９の下側部分と第２の端子部３４の外部突出部３９の下側部分とをそれぞれ垂直に、かつ、帯状に形成された外部突出部２９と外部突出部３９とが１つの仮想的な平面に含まれるように保持する。第１の端子部２４の上側部分は、図７（ａ）に示すように、外側凹部４９ａの底面から垂直に突出しており、第２の端子部３４の上側部分も同様に突出している。外側凹部４９ｂは、外部装置等のコネクタの凸部と直接に結合される部分である。 The rectangular cylindrical portion 42 of the main body portion 40 is a portion that is directly coupled to a connector such as an external device, and is formed so as to extend along the central axis of the case 68 from the outer surface of the disc-like portion 41. . The rectangular cylindrical portion 42 is disposed at a position that is eccentric with respect to the disc-shaped portion 41. However, the rectangular cylindrical portion 42 is arranged, for example, at the center depending on the situation of the device on which the solenoid 10 is mounted. You may change suitably, such as arranging. Similarly, the length, diameter, and outer shape of the rectangular cylindrical portion 42 in the central axis direction may be appropriately changed according to the device to be mounted. In addition, a terminal holding through hole 48 a and a terminal holding through hole 48 b extending along the central axis of the case 68 are formed in the rectangular cylindrical portion 42 and the disc-like portion 41. The terminal holding through-hole 48a and the terminal holding through-hole 48b respectively connect a lower portion of the external protruding portion 29 of the first terminal portion 24 and a lower portion of the external protruding portion 39 of the second terminal portion 34. The external projecting portion 29 and the external projecting portion 39 formed vertically and in a belt shape are held so as to be included in one virtual plane. As shown in FIG. 7A, the upper portion of the first terminal portion 24 protrudes vertically from the bottom surface of the outer recessed portion 49a, and the upper portion of the second terminal portion 34 also protrudes in the same manner. The outer concave portion 49b is a portion that is directly coupled to a convex portion of a connector such as an external device.

また、本体部４０の円板状部４１は、図１１（ｂ）に示すように、底面側の中央に中央凹部４７ａが形成されている。中央凹部４７ａは、略矩形の凹部に形成されており、図９（ｂ）に示すように、その内部に第１の端子部２４の外部突出部２９に連続する第２の水平中間部２８と、第２の端子部３４の外部突出部３９に連続する第２の水平中間部３８とがそれぞれ配置されている。また、図９（ｂ）及び図１０（ｃ）に示すように、中央凹部４７ａから円板状部４１の外周側に、かつ、互いに背向するように溝部状凹部４７ｂと溝部状凹部４７ｃとが形成されている。溝部状凹部４７ｂと溝部状凹部４７ｃとは、その内部に第１の端子部２４の第２の水平中間部２８に連続する第１の水平中間部２７と、第２の端子部３４の第２の水平中間部３８に連続する第１の水平中間部３７とがそれぞれ配置されている。したがって、第１の水平中間部２７と第１の水平中間部３７とは溝部状凹部４７ｂと溝部状凹部４７ｃとにそれぞれ保持されており、ソレノイド１０の組立工程において、あるいは、外部装置に実装後に外部からの衝撃によって第１の水平中間部２７と第１の水平中間部３７とが位置ずれすることが防止される。中央凸部４７ｆは、図２に示すように、スリーブ７３に当接しており、可動磁極６２の摺動によってスリーブ７３が位置ずれすることを防止する。 Further, as shown in FIG. 11B, the disc-like portion 41 of the main body 40 has a central concave portion 47a formed at the center on the bottom surface side. The central concave portion 47a is formed in a substantially rectangular concave portion, and as shown in FIG. 9B, a second horizontal intermediate portion 28 that is continuous with the external projecting portion 29 of the first terminal portion 24 is formed therein. A second horizontal intermediate portion 38 that is continuous with the external protrusion 39 of the second terminal portion 34 is disposed. Further, as shown in FIG. 9B and FIG. 10C, the groove-shaped recess 47b and the groove-shaped recess 47c are arranged so as to face away from the outer periphery of the disk-shaped portion 41 from the central recess 47a.

The groove-shaped concave portion 47b and the groove-shaped concave portion 47c include a first horizontal intermediate portion 27 that is continuous with the second horizontal intermediate portion 28 of the first terminal portion 24 and a second portion of the second terminal portion 34. The first horizontal intermediate portion 37 that is continuous with the horizontal intermediate portion 38 is disposed. Therefore, the first horizontal intermediate portion 27 and the first horizontal intermediate portion 37 are respectively held in the groove-like concave portion 47b and the groove-like concave portion 47c, and in the assembly process of the solenoid 10 or after being mounted on an external device. It is possible to prevent the first horizontal intermediate portion 27 and the first horizontal intermediate portion 37 from being displaced due to an external impact. As shown in FIG. 2, the central protrusion 47 f is in contact with the sleeve 73, and prevents the sleeve 73 from being displaced due to the sliding of the movable magnetic pole 62.

くわえて、図１１（ｂ）に示すように、溝部状凹部４７ｂと溝部状凹部４７ｃとに連続するように、外周側凹部４７ｄと外周側凹部４７ｅとが形成されている。外周側凹部４７ｄと外周側凹部４７ｅとには、図９（ｂ）に示すように、内部に第１の水平中間部２７と垂直中間部２５との端部と、第１の水平中間部３７と垂直中間部３５との端部とが配置されている。以上の外周側凹部４７ｄ、溝部状凹部４７ｂ、中央凹部４７ａ、溝部状凹部４７ｃ及び外周側凹部４７ｅは、一直線上に並ぶように配置されており、第１の端子部２４及び第２の端子部３４の一部がその内部に配置されることによって第１の端子部２４及び第２の端子部３４を保持している。なお、外周側凹部４７ｄ、溝部状凹部４７ｂ、中央凹部４７ａ、溝部状凹部４７ｃ及び外周側凹部４７ｅの配置は、第１の端子部２４及び第２の端子部３４の構成に応じて、例えば「く」の字状にするなど適宜変更することが可能である。 In addition, as shown in FIG. 11B, an outer peripheral recess 47d and an outer recess 47e are formed so as to be continuous with the groove recess 47b and the groove recess 47c. As shown in FIG. 9B, the outer peripheral recess 47 d and the outer peripheral recess 47 e include an end portion of the first horizontal intermediate portion 27 and the vertical intermediate portion 25, and a first horizontal intermediate portion 37. And an end portion of the vertical intermediate portion 35 are disposed. The outer peripheral concave portion 47d, the groove-shaped concave portion 47b, the central concave portion 47a, the groove-shaped concave portion 47c, and the outer peripheral concave portion 47e are arranged so as to be aligned in a straight line, and the first terminal portion 24 and the second terminal portion. A part of 34 is disposed therein to hold the first terminal portion 24 and the second terminal portion 34. The arrangement of the outer peripheral recess 47d, the groove recess 47b, the central recess 47a, the groove recess 47c, and the outer recess 47e depends on the configuration of the first terminal portion 24 and the second terminal portion 34, for example, It can be changed as appropriate, for example, in the shape of "".

また、外周側凹部４７ｄとの外周側凹部４７ｅのさらに外周側には、保護板部４５と保護板部４４とが設けられている。保護板部４５と保護板部４４とは、後述するように、ソレノイド１０を組み立てた状態において、第１の端子部２４及び第２の端子部３４と第１の端子接続部材２０及び第２の端子接続部材３０を接触させた部分を保護すると共に、ソレノイド１０の組立時においてコネクタ１１の本体部４０の方向を設定するために利用される。保護板部４５と保護板部４４との巻胴部５１側の面には、突起部４５ａと突起部４４ａとが設けられている。突起部４５ａと突起部４４ａとは、突出部５６の貼り付け部５６ａと突出部５７の貼り付け部５７ａとの下端部に係止されることによって、ソレノイド１０の組立作業中に、本体部４０の位置がずれることを防止する。同時に、突起部４５ａと突起部４４ａとは、第１の端子部２４の突起部２６と第２の端子部３４の突起部３６とを第１の端子接続部材２０の第１の水平領域２１と第２の端子接続部材３０の第１の水平領域３１とに押し付けることによって、第１の端子部２４の突起部２６と第２の端子部３４の突起部３６とを第１の端子接続部材２０の第１の水平領域２１と第２の端子接続部材３０の第１の水平領域３１とが確実に電気的に接続されるようにする。すなわち、スナップフィットによってコネクタ１１を固定する役割だけでなく、コイル７０に対する確実な電力供給を確保する役割も併せ持っているのである。さらに、本体部４０の底面側には、略円形状で、中央凹部４７ａを囲むように、かつ、中央凹部４７ａよりも浅いスリーブ用凹部４６が形成されている。スリーブ用凹部４６には、図１に示すように、スリーブ７２の前面部７５及び近傍部分が挿入された状態になる。スリーブ用凹部４６を設けることにより、本体部４０とスリーブ７２との間の不要な空間を省き、ソレノイド１０の小型化を可能としている。 Further, a protective plate portion 45 and a protective plate portion 44 are provided on the outer peripheral side of the outer peripheral side concave portion 47e and the outer peripheral side concave portion 47e.

A direction in which the external projecting portion 29 and the external projecting portion 39 arranged so as to be included in one imaginary plane are extended horizontally and in a direction opposite to each other by the intermediate portion 27. Has been switched. The vertical intermediate portion 25 and the vertical intermediate portion extending vertically downward with respect to the first horizontal intermediate portion 27 and the first horizontal intermediate portion 27 at a position near the outer peripheral surface of the second hook-shaped portion 53 of the bobbin 50. The part 35 is configured to be continuous. The vertical intermediate portion 25 and the vertical intermediate portion 35 are arranged in parallel to each other and not included in one virtual plane. As shown in FIGS. 7 and 8, the vertical intermediate portion 25 and the vertical intermediate portion 35 are disposed along the surfaces of the protruding portion 56 and the protruding portion 57 of the bobbin 50.

さらに、垂直中間部２５と垂直中間部３５との下端部には、第１の端子接続部材２０と第２の端子接続部材３０とに確実に接触させるために突起部２６と突起部３６とをそれぞれ設けている。突起部２６と突起部３６とは、図１２（ｃ）に示すように、互いに対向するように、つまり、第１の端子接続部材２０と第２の端子接続部材３０とが配置される側に垂直中間部２５と垂直中間部３５との下端部をそれぞれ突出させたものである。 Further, at the lower end portions of the vertical intermediate portion 25 and the vertical intermediate portion 35, the protruding portion 26 and the protruding portion 36 are provided in order to securely contact the first terminal connecting member 20 and the second terminal connecting member 30. Each is provided. As shown in FIG. 12C, the protrusion 26 and the protrusion 36 are opposed to each other, that is, on the side where the first terminal connection member 20 and the second terminal connection member 30 are arranged. The lower end portions of the vertical intermediate portion 25 and the vertical intermediate portion 35 are respectively protruded.

第１の端子接続部材２０と第２の端子接続部材３０とは、本来端子部の一部分であるべきところを端子部から分割することによって、コネクタの設計変更や、形状又はソレノイドの中心軸方向における長さの異なるコネクタを複数種準備しても、ボビンなど他の部品に形状等を変更する必要がなく、かつ、組立作業も容易になるようにしたものである。すなわち、図１３に示すように、帯状の金属材を２カ所で屈曲させて形成したものである。第１の端子接続部材２０は、第２の水平領域２２の両端部に第１の水平領域２１と第３の水平領域２３とが屈曲して連続し、かつ、第１の水平領域２１と第３の水平領域２３とが直角をなすように形成されている。同様に、第２の端子接続部材３０は、第２の水平領域３２の両端部に第１の水平領域３１と第３の水平領域３３とが屈曲して連続し、かつ、第１の水平領域３１と第３の水平領域３３とが直角をなすように形成されている。 The first terminal connecting member 20 and the second terminal connecting member 30 are divided in the design of the connector or in the central axis direction of the solenoid by dividing the portion that should originally be a part of the terminal portion from the terminal portion. Even if a plurality of types of connectors having different lengths are prepared, it is not necessary to change the shape or the like to other parts such as a bobbin, and the assembling work is facilitated. That is, as shown in FIG. 13, a band-shaped metal material is formed by bending at two points. The first terminal connection member 20 includes a first horizontal region 21 and a third horizontal region 23 that are bent and continuous at both ends of the second horizontal region 22, and the first horizontal region 21 and the first horizontal region 21 3 horizontal regions 23 are formed so as to form a right angle. Similarly, the second terminal connection member 30 includes a first horizontal region 31 and a third horizontal region 33 that are bent and continuous at both ends of the second horizontal region 32, and the first horizontal region. 31 and the third horizontal region 33 are formed so as to form a right angle.

また、第１の端子接続部材２０と第２の端子接続部材３０とは、ソレノイド１０に組み込んだ状態において、仮想的な８角形の６辺のなすような位置に配置されている。第１の水平領域２１と第３の水平領域２３とは、図３に示しているボビン５０の貼り付け部５６ａと貼り付け部５６ｂとに貼り付けられると共に、突起部２６と突起部３６とに接する部分でもある。第３の水平領域２３と第３の水平領域３３とは、図８（ｂ）に示すように、コイルワイヤ導出部７１ａとコイルワイヤ導出部７１ｂとを第３の水平領域２３と第３の水平領域３３とにそれぞれ巻回している。そこで、図１３（ｂ）に示すように、第３の水平領域２３と第３の水平領域３３とを第２の水平領域２２と第２の水平領域３２よりも上下方向の幅が狭くなるように形成して、コイルワイヤ導出部７１ａとコイルワイヤ導出部７１ｂとが第２の鍔状部５３の表面から浮き上がり、貼り付け部５６ａと貼り付け部５６ｂとに正しく貼り付けできなくなることを防止している。 Further, the first terminal connection member 20 and the second terminal connection member 30 are arranged at positions formed by six sides of a virtual octagon when they are incorporated in the solenoid 10. The first horizontal region 21 and the third horizontal region 23 are attached to the attaching portion 56a and the attaching portion 56b of the bobbin 50 shown in FIG. It is also the part that touches. As shown in FIG. 8B, the third horizontal region 23 and the third horizontal region 33 are different from the third horizontal region 23 and the third horizontal region. Each region is wound around the region 33. Therefore, as shown in FIG. 13B, the vertical width of the third horizontal region 23 and the third horizontal region 33 is narrower than that of the second horizontal region 22 and the second horizontal region 32. The coil wire lead-out portion 71a and the coil wire lead-out portion 71b are lifted from the surface of the second hook-like portion 53, and are prevented from being correctly attached to the attachment portion 56a and the attachment portion 56b. ing.

また、第１の端子接続部材２０と第２の端子接続部材３０とは、リード線とは異なり、導電材が剥き出しの状態になっているが、後述する三日月状肉付け部５４及び覆い部５４ｂと三日月状肉付け部５５及び覆い部５５ｂとによって囲まれることにとって、磁性金属からなる補助磁極６５や他の導電材との不要な接触が防止される。なお、第１の端子接続部材２０及び第２の端子接続部材３０は、高度な加工が必要になるが、巻胴部５１の外径に合わせた円弧状の形状にしてもよい。また、第３の水平領域２３と第３の水平領域３３とを水平方向にさらに長く形成し、垂直方向の折り目に沿って、かつ、コイルワイヤ導出部７１ａとコイルワイヤ導出部７１ｂとを挟んだ状態でヒュージングしてもよい。 Further, unlike the lead wire, the first terminal connecting member 20 and the second terminal connecting member 30 are in a state where the conductive material is exposed, but a crescent-shaped fleshing portion 54 and a covering portion 54b, which will be described later, By being surrounded by the crescent moon-shaped portion 55 and the cover portion 55b, unnecessary contact with the auxiliary magnetic pole 65 made of magnetic metal and other conductive materials is prevented. The first terminal connecting member 20 and the second terminal connecting member 30 need to be highly processed, but may have an arc shape that matches the outer diameter of the winding body 51. Further, the third horizontal region 23 and the third horizontal region 33 are formed to be longer in the horizontal direction, and the coil wire lead-out portion 71a and the coil wire lead-out portion 71b are sandwiched along the vertical fold. You may fuse in the state.

以上のように、第１の端子部２４及び第２の端子部３４と、第１の端子接続部材２０と第２の端子接続部材３０とは、ソレノイド１０を組み立てた状態において、突起部２６と突起部３６とが第１の水平領域２１と第１の水平領域３１とに接するようにしたので、ヒュージングなどの接続のための作業が不要になり、作業者の負担を軽減できる。また、ケース６８に対して円板状部４１を固定でき、突起部２６と突起部３６とが第１の水平領域２１と第１の水平領域３１とに接するのであれば、第１の端子部２４及び第２の端子部３４の他の部分の形状や、矩形筒状部４２の形状は特段の制約なく変更可能である。そこで例えば、形状が異なる多数の種類のコネクタを準備しておき、コネクタ以外の部品を全て共通する構成とすれば、コネクタの種類に応じた多数の製品を市場に供給することが可能となる。 As described above, the first terminal portion 24 and the second terminal portion 34, the first terminal connecting member 20, and the second terminal connecting member 30 are the protrusions 26 in the assembled state of the solenoid 10. Since the protrusion 36 is in contact with the first horizontal region 21 and the first horizontal region 31, work for connection such as fusing is unnecessary, and the burden on the operator can be reduced. In addition, if the disc-like portion 41 can be fixed to the case 68 and the protrusion 26 and the protrusion 36 are in contact with the first horizontal region 21 and the first horizontal region 31, the first terminal portion The shapes of the other portions of the 24 and the second terminal portions 34 and the shape of the rectangular tubular portion 42 can be changed without any particular limitation. Therefore, for example, if a large number of types of connectors having different shapes are prepared and all components other than the connectors are configured in common, a large number of products corresponding to the types of connectors can be supplied to the market.

以上のように、本発明の実施の形態によれば、コネクタ１１の第１の保護板部４４の突起部４４ａと第２の保護板部４５の突起部４５ａとを突出部５６の貼り付け部５６ａと突出部５７の貼り付け部５７ａとにスナップフィットさせることにより、コネクタ１１とコイル７０との機械的接続が可能であり、ひいては、補助磁極６５をコネクタ１１とコイル７０との間に挟み込んでおくことができる。すなわち、ソレノイド１０の組立時に、コイル７０、補助磁極６５及びコネクタ１１を一体のものとして取り扱うことができ、作業の利便性が良い。また、スナップフィットにより接続された第１の保護板部４４の突起部４４ａと第２の保護板部４５の突起部４５ａとには、第１の端子部２４の突起部２６と第２の端子部３４の突起部３６とを押さえつける方向に応力を与えているため、振動や衝撃があっても第１の端子部２４及び第２の端子部３４と第１の端子接続部材２０及び第２の端子接続部材３０との接続不良を防止できる。さらに、第１の保護板部４４の突起部４４ａと第２の保護板部４５とは、第１の端子部２４の垂直中間部２５と第２の端子部３４の垂直中間部３５とが他の金属部材と接触することを防ぐ機能も持っている。言い換えると、コネクタ１１をケース６８に固定するだけで、コネクタ１１の第１の端子部２４及び第２の端子部３４を第１の端子接続部材２０及び第２の端子接続部材３０を介してコイル７０に接続することができる。そこで、ボビン５０、第１の端子接続部材２０及び第２の端子接続部材３０を特定の１種類の形状及び大きさに設定すると共に、コイルワイヤ導出部７１ａ及び７１ｂと第１の端子接続部材２０及び第２の端子接続部材３０をあらかじめ接続しておく一方、コネクタ１１だけを設計変更などに応じて形状又は大きさを変更するようにすれば、コネクタ１１の形状又は大きさに変更があっても、ヒュージング等の作業負担が増加することがなく、製造コストの増大も抑えることができる。また、第１の配線路５４ａ及び第２の配線路５５ａが第１の端子接続部材２０及び第２の端子接続部材３０の絶縁被覆として機能するので、コネクタ１１の第１の端子部２４又は第２の端子部３４や、補助磁極６５を非常に接近させて配置することができ、コネクタ１１の設計が容易になる。ひいては、コネクタ１１の形状又は大きさに変更があっても製造コストの増大を抑えることができる。さらに、コネクタ１１の第１の端子部２４及び第２の端子部３４と第１の端子接続部材２０及び第２の端子接続部材３０との接続部分が第１の保護板部４４及び第２の保護板部４５で覆われるので、ソレノイド１０の組立作業中にこの接続部分を保護することができる。ひいては、作業者の負担を軽減できる。くわえて、第１の端子部２４の第１の水平中間部２７及び第２の端子部３４の第１の水平中間部３７が溝部状凹部４７ｂ及び溝部状凹部４７ｃによって保持されるので、ソレノイド１０の組立後に第１の端子部２４の第１の水平中間部２７及び第２の端子部３４の第１の水平中間部３７が位置ずれしたり揺動したりすることを防止できる。 As described above, according to the embodiment of the present invention, the protrusion 44 a of the first protection plate 44 and the protrusion 45 a of the second protection plate 45 of the connector 11 are attached to the protrusion 56. The connector 11 and the coil 70 can be mechanically connected by snap-fitting to the affixed portion 57a of the protrusion 56a and the auxiliary magnetic pole 65 is sandwiched between the connector 11 and the coil 70. I can leave. That is, when assembling the solenoid 10, the coil 70, the auxiliary magnetic pole 65, and the connector 11 can be handled as a single unit, and the convenience of work is good. In addition, the protrusions 44 a of the first protection plate 44 and the protrusions 45 a of the second protection plate 45 connected by snap-fit are connected to the protrusions 26 of the first terminal 24 and the second terminals. Since stress is applied in the direction of pressing the protrusion 36 of the portion 34, the first terminal portion 24, the second terminal portion 34, the first terminal connecting member 20, and the second terminal are provided even when there is vibration or impact. Connection failure with the terminal connection member 30 can be prevented. Further, the protrusion 44 a of the first protective plate portion 44 and the second protective plate portion 45 are different from the vertical intermediate portion 25 of the first terminal portion 24 and the vertical intermediate portion 35 of the second terminal portion 34. It also has a function to prevent contact with metal members. In other words, the first terminal portion 24 and the second terminal portion 34 of the connector 11 can be coiled via the first terminal connecting member 20 and the second terminal connecting member 30 only by fixing the connector 11 to the case 68. 70 can be connected. Therefore, the bobbin 50, the first terminal connection member 20 and the second terminal connection member 30 are set to one specific type and size, and the coil wire lead-out portions 71a and 71b and the first terminal connection member 20 are set. If the shape or size of only the connector 11 is changed according to a design change or the like while the second terminal connecting member 30 is connected in advance, the shape or size of the connector 11 is changed. However, the work load such as fusing does not increase, and an increase in manufacturing cost can be suppressed. In addition, since the first wiring path 54a and the second wiring path 55a function as insulating coatings for the first terminal connection member 20 and the second terminal connection member 30, the first terminal portion 24 of the connector 11 or the second The two terminal portions 34 and the auxiliary magnetic pole 65 can be arranged very close to each other, and the connector 11 can be easily designed. As a result, even if the shape or size of the connector 11 is changed, an increase in manufacturing cost can be suppressed. Furthermore, the connection part of the 1st terminal part 24 and the 2nd terminal part 34 of the connector 11, and the 1st terminal connection member 20 and the 2nd terminal connection member 30 is the 1st protection board part 44 and 2nd. Since it is covered with the protection plate portion 45, this connecting portion can be protected during the assembly operation of the solenoid 10. As a result, the burden on the operator can be reduced. In addition, since the first horizontal intermediate portion 27 of the first terminal portion 24 and the first horizontal intermediate portion 37 of the second terminal portion 34 are held by the groove-like recess 47b and the groove-like recess 47c, the solenoid 10 It is possible to prevent the first horizontal intermediate portion 27 of the first terminal portion 24 and the first horizontal intermediate portion 37 of the second terminal portion 34 from being displaced or swung after the assembly.
