　［コイル］
　コイル１０は、図２に示すように金属から成るコイル線２０を有している。コイル線２０は、後述するコイルボビン１１に巻回される。これにより、後述するコイルボビン１１の周りにコイル１０が構成されている。そして、コイル１０は、コイル線２０に電流を流すことによって磁界を発生する。 [coil]
The coil 10 has a coil wire 20 made of metal as shown in FIG. The coil wire 20 is wound around a coil bobbin 11 which will be described later. Thus, the coil 10 is configured around a coil bobbin 11, which will be described later. The coil 10 generates a magnetic field by applying a current to the coil wire 20 .
　［コイルボビン］
　コイルボビン１１は、コイル線２０を巻回させる部材である。また、コイルボビン１１は、巻回されるコイル線２０によって構成されるコイル１０を保持する部材である。コイルボビン１１は、樹脂製であり、本実施形態においてＰＥ、ＰＰ、又はＰＢＴから成る。そして、コイルボビン１１は、図３に示すように胴部２１と、第１鍔部２２と、第２鍔部２３と、を有している。更に詳細に説明すると、コイルボビン１１は、円筒状に形成されている。そして、コイルボビン１１の中には、図示しない磁性体（例えば、後述ずるプランジャ６３等）が軸線Ｌ１に沿って相対移動可能に挿入される。なお、コイルボビン１１の断面は円形に限定されず、例えば、断面多角形の筒状に形成されてもよい。 [Coil bobbin]
The coil bobbin 11 is a member around which the coil wire 20 is wound. Also, the coil bobbin 11 is a member that holds the coil 10 configured by the coil wire 20 to be wound. The coil bobbin 11 is made of resin, and is made of PE, PP, or PBT in this embodiment. And the coil bobbin 11 has the body part 21, the 1st collar part 22, and the 2nd collar part 23, as shown in FIG. More specifically, the coil bobbin 11 is cylindrical. A magnetic body (for example, a plunger 63 to be described later) is inserted into the coil bobbin 11 so as to be relatively movable along the axis L1. Note that the cross section of the coil bobbin 11 is not limited to a circular shape, and may be formed in a tubular shape with a polygonal cross section, for example.
　胴部２１は、外周面にコイル線２０が巻回される筒状部材である。そして、胴部２１は、胴部本体３１と、保護部材３２とを有している。更に詳細に説明すると、胴部２１は、円筒状且つ薄肉形成されている。また、胴部２１は、胴部２１の軸線が延びる軸方向に延在している。なお、胴部２１の軸線は、本実施形態において前述する軸線Ｌ１と一致している。 The body portion 21 is a cylindrical member around the outer peripheral surface of which the coil wire 20 is wound. The trunk portion 21 has a trunk portion main body 31 and a protective member 32 . More specifically, the body portion 21 is cylindrical and thin. Further, the trunk portion 21 extends in the axial direction in which the axis of the trunk portion 21 extends. In addition, the axis line of the trunk|drum 21 corresponds with the axis line L1 mentioned above in this embodiment.
　胴部本体３１は、筒状に形成されている。そして、胴部本体３１は、外周面にコイル１０が巻回されている。胴部本体３１は、本実施形態において円筒状に形成されている。そして、胴部本体３１の内外方向の厚みは、後で詳述する保護部材３２と略同じ又は少し厚い程度である。なお、胴部本体３１の内外方向の厚みは、本実施形態において胴部本体３１の半径方向の厚みである。また、本実施形態では、胴部本体３１は、保護部材３２全体を埋設できる程度に薄肉形成されている。 The trunk main body 31 is formed in a tubular shape. A coil 10 is wound around the outer peripheral surface of the trunk body 31 . The trunk main body 31 is formed in a cylindrical shape in this embodiment. The thickness of the torso main body 31 in the inside-outside direction is substantially the same as or slightly thicker than that of the protective member 32, which will be described in detail later. In addition, the thickness of the trunk|drum main body 31 in the inside-outside direction is the thickness of the trunk|drum main body 31 in the radial direction in this embodiment. In addition, in this embodiment, the trunk body 31 is formed thin enough to allow the entire protection member 32 to be embedded.
　保護部材３２は、通電部材１４を保護するシート状の部材である。更に詳細に説明すると、保護部材３２は、図４に示すように２つの保護シート４１，４２を有している。２つの保護シート４１，４２は、本実施形態において胴部本体３１と同様の合成樹脂から成る平面視矩形状の薄いシートである。そして、保護部材３２は、２つの保護シート４１，４２の主面同士を突き合わせるように重ね合わして構成される。それ故、保護部材３２は、保護シート４１、４２によって積層シート状に形成されている。保護部材３２は、胴部本体３１の外周と同様の形状をしており、本実施形態では、保護部材３２は、胴部本体３１と同じ曲率半径で湾曲している。そして、保護部材３２は、胴部２１の一部を形成するように胴部本体３１に埋設されている。なお、本実施形態では、保護部材３２全体が胴部本体３１に埋設されているが、必ずしもこのように構成されている必要はない。即ち、保護部材３２の厚み方向一方側の面が胴部本体３１から表出するように形成されてもよい。 The protective member 32 is a sheet-like member that protects the current-carrying member 14 . More specifically, the protective member 32 has two protective sheets 41 and 42 as shown in FIG. The two protective sheets 41 and 42 are thin rectangular sheets in a plan view made of the same synthetic resin as the trunk main body 31 in this embodiment. The protective member 32 is configured by superimposing two protective sheets 41 and 42 so that their main surfaces face each other. Therefore, the protective member 32 is formed in a laminated sheet shape by the protective sheets 41 and 42 . The protection member 32 has the same shape as the outer circumference of the trunk body 31 , and in this embodiment, the protection member 32 is curved with the same radius of curvature as the trunk body 31 . The protective member 32 is embedded in the body portion main body 31 so as to form a part of the body portion 21 . In this embodiment, the entire protective member 32 is embedded in the trunk main body 31, but it is not always necessary to be configured in this way. That is, the protective member 32 may be formed such that one surface in the thickness direction is exposed from the trunk body 31 .
　保護シート４１，４２の各々には長手方向に延在する複数の配線用溝４１ａ，４２ａが主面に形成されている。保護シート４１，４２の各々には、本実施形態において一対の配線用溝４１ａ，４２ａが形成されている。なお、配線用溝４１ａ及び配線用溝４２ａは、必ずしも両方が形成されている必要はなく、少なくとも一方が形成されていればよい。また、一方の保護シート４１に形成されている配線用溝４１ａの各々は、他方の保護シート４２に形成される４２ａの各々に対向するように形成されている。そして、一対の配線用溝４１ａ，４２ａは、２つの保護シート４１，４２を重ね合わせた際に対向する配線用溝４２ａ，４１ａと共に配線用通路３２ａ，３２ｂを形成する。 A plurality of wiring grooves 41a and 42a extending in the longitudinal direction are formed on the main surface of each of the protective sheets 41 and 42 . A pair of wiring grooves 41a and 42a are formed in each of the protection sheets 41 and 42 in this embodiment. Note that both the wiring groove 41a and the wiring groove 42a need not necessarily be formed, and at least one of them may be formed. Each of the wiring grooves 41a formed in one protective sheet 41 is formed so as to face each of the grooves 42a formed in the other protective sheet 42. As shown in FIG. The pair of wiring grooves 41a and 42a form wiring passages 32a and 32b together with the wiring grooves 42a and 41a facing each other when the two protective sheets 41 and 42 are overlapped.
　また、保護シート４１，４２は、幅方向の外周縁部両側に複数の切欠き４１ｂ，４２ｂが夫々形成されている。なお、図４では、保護シート４１，４２の切欠き４１ｂ、４２ｂについては、一か所だけ符号を付してその他の箇所の符号は省略されている。保護シート４１，４２の外周縁部の各々には、本実施形態において７個の切欠き４１ｂ，４２ｂが形成されている。４つの切欠き４１ｂ，４２ｂは、互いに間隔をあけて配置されている。また、保護シート４１，４１の切欠き４１ｂ，４２ｂは、保護シート４１，４２を重ね合わせた際に互い違いに位置するように配置されている。即ち、保護部材３２では、厚み方向一方から見ると一方の保護シート４１の切欠き４１ｂから他方の保護シート４２の切欠き４２ｂの間の部分が表出する。また、厚み方向他方から見ると他方の保護シート４２の切欠き４２ｂから一方の保護シート４１の切欠き４１ｂの間の部分が表出している。 In addition, the protective sheets 41 and 42 are formed with a plurality of cutouts 41b and 42b on both sides of the outer peripheral edges in the width direction, respectively. In FIG. 4, only one portion of the cutouts 41b and 42b of the protective sheets 41 and 42 is given a reference numeral, and the reference numerals of the other portions are omitted. Seven cutouts 41b and 42b are formed in each of the outer peripheral edge portions of the protective sheets 41 and 42 in this embodiment. The four cutouts 41b and 42b are spaced apart from each other. Moreover, the notches 41b and 42b of the protective sheets 41 and 41 are arranged so as to be alternately positioned when the protective sheets 41 and 42 are overlapped. That is, in the protective member 32, when viewed from one side in the thickness direction, a portion between the notch 41b of one protective sheet 41 and the notch 42b of the other protective sheet 42 is exposed. When viewed from the other thickness direction, the portion between the notch 42b of the other protective sheet 42 and the notch 41b of the one protective sheet 41 is exposed.
　第１鍔部２２は、図１及び図３に示すように胴部２１の軸方向一方側の端部に形成されている。即ち、第１鍔部２２は、胴部２１の軸方向一端部に形成されている。また、第１鍔部２２は、胴部２１の軸方向一端部から外方（半径方向外側）に張り出すように形成されている。更に詳細に説明すると、第１鍔部２２は、軸方向一端部において周方向全周にわたって形成されている。また、第１鍔部２２の半径方向の高さは、胴部２１に構成されているコイル１０の半径方向の高さより高く形成されている。 The first brim portion 22 is formed at one end portion of the body portion 21 in the axial direction, as shown in FIGS. That is, the first collar portion 22 is formed at one axial end portion of the body portion 21 . The first collar portion 22 is formed to protrude outward (radially outward) from one axial end portion of the body portion 21 . More specifically, the first flange portion 22 is formed along the entire circumference at one end portion in the axial direction. Also, the radial height of the first collar portion 22 is higher than the radial height of the coil 10 formed in the body portion 21 .
　第２鍔部２３は、胴部２１の軸方向他方側の端部に形成されている。即ち、第２鍔部２３は、胴部２１の軸方向他端部に形成されている。また、第２鍔部２３は、胴部２１の軸方向他端部から外方（半径方向外側）に張り出すように形成されている。更に詳細に説明すると、第２鍔部２３は、軸方向他端部において周方向全周にわたって形成されている。また、第２鍔部２３の半径方向の高さは、胴部２１に構成されているコイル１０の半径方向の高さより高く形成されている。そして第２鍔部２３は、第１鍔部２２との間に円環状のコイル収容空間２４を形成している。そして、コイル収容空間２４において、胴部２１の外周面にコイル線２０が巻回されることによってコイル１０が構成されている。 The second brim portion 23 is formed at the end portion of the body portion 21 on the other side in the axial direction. That is, the second collar portion 23 is formed at the other axial end portion of the body portion 21 . The second collar portion 23 is formed to protrude outward (radially outward) from the other axial end portion of the body portion 21 . More specifically, the second collar portion 23 is formed along the entire circumference at the other end in the axial direction. In addition, the radial height of the second collar portion 23 is higher than the radial height of the coil 10 formed in the body portion 21 . The second flange 23 forms an annular coil housing space 24 with the first flange 22 . The coil 10 is configured by winding the coil wire 20 around the outer peripheral surface of the body portion 21 in the coil housing space 24 .
　また、第２鍔部２３は、図１及び図５にも示すように、その一部に二重壁部２３ａ，２３ｂを有している。即ち、第２鍔部２３は、２つの壁部２３ａ，２３ｂを有している。なお、二重壁部２３ａ，２３ｂは、第２鍔部２３の全周にわたって形成されてもよい。２つの壁部２３ａ，２３ｂは、第２鍔部２３の周方向の一部又は全部において軸方向に離間している。これにより、２つの壁部２３ａ，２３ｂの間には、接続溝２３ｃが形成されている。即ち、接続溝２３ｃは、第２鍔部２３の外周面において周方向に延在している。また、２つの壁部２３ａ，２３ｂのうち第１鍔部２２側にある一方の壁部２３ａには、切欠き通路２３ｄ，２３ｅが形成されている。切欠き通路２３ｄ，２３ｅは、共に壁部２３ａを貫通している。そして、切欠き通路２３ｄ，２３ｅは、接続溝２３ｃとコイル収容空間２４とを連通している。各切欠き通路２３ｄ，２３ｅには、コイル線２０が夫々通されている。これにより、コイル線２０の両端部分が二重壁部２３ａ，２３ｂの間に引き込まれている。また、他方の壁部２３ｂには、図６に示すように連通孔２３ｆが形成されている。連通孔２３ｆは、壁部２３ｂを貫通している。そして、連通孔２３ｆは、第２鍔部２３において第２コネクタ部１３から周方向に離して配置されている。 In addition, as shown in FIGS. 1 and 5, the second collar portion 23 has double wall portions 23a and 23b in its part. That is, the second collar portion 23 has two wall portions 23a and 23b. Note that the double wall portions 23 a and 23 b may be formed over the entire circumference of the second collar portion 23 . The two walls 23a and 23b are axially separated in part or all of the circumferential direction of the second flange 23 . Thereby, a connecting groove 23c is formed between the two wall portions 23a and 23b. That is, the connection groove 23c extends in the circumferential direction on the outer peripheral surface of the second collar portion 23. As shown in FIG.

　また、第１コネクタ部１２は、図３に示すように軸方向一端部を突き出させるように第１鍔部２２に設けられている。なお、インサート部品である第１コネクタ部１２の軸方向他端部が第１鍔部２２にインサートされた状態でコイルボビン１１が成形（即ちインサート成形）されるので、第１コネクタ部１２の軸方向他端部は第１鍔部２２と一体的に形成されている。 Also, the first connector portion 12 is provided on the first collar portion 22 so as to protrude at one end in the axial direction, as shown in FIG. Since the coil bobbin 11 is molded (that is, insert-molded) in a state in which the other axial end of the first connector portion 12, which is an insert component, is inserted into the first collar portion 22, the axial direction of the first connector portion 12 is The other end is formed integrally with the first collar portion 22 .

The second connector portion 13 shown in FIG. 1 is provided on the second collar portion 23 of the body portion 21 . In addition, the second connector portion 13 is arranged at a position radially different from that of the first connector portion 12 when viewed in the axial direction. More specifically, the second connector portion 13 is made of synthetic resin. In this embodiment, the second connector portion 13 is made of the same material as the coil bobbin 11 . And the 2nd connector part 13 is formed in a column shape. In addition, the first connector portion 12 is not limited to a columnar shape, and may be formed in a columnar shape having a polygonal cross section. Further, an insertion hole 13 a is formed in the second connector portion 13 . The insertion hole 13a passes through the second connector portion 13 in the axial direction. In this embodiment, there are a plurality of insertion holes 13a, and two insertion holes 13a are formed.

The second connector portion 13 is connected to a device connector (for example, a device connector 53a to be described later) that is connected to an electronic device such as a control device.
　また、第２コネクタ部１３は、図３に示すように軸方向一方側の部分である軸方向一端部をインサートさせるようにして第２鍔部２３に設けられている。そして、第２コネクタ部１３は、軸方向他方側の部分である軸方向他端部を第２鍔部２３から突き出させている。従って、第２コネクタ部１３の軸方向他端部もまたコイルボビン１１をインサート成形する際に第２鍔部２３と一体的に形成されている。 Further, the second connector portion 13 is provided on the second collar portion 23 so that one axial end portion, which is a portion on one axial side, is inserted as shown in FIG. The second connector portion 13 protrudes from the second brim portion 23 at the other axial end portion, which is the other portion in the axial direction. Therefore, the other end in the axial direction of the second connector portion 13 is also formed integrally with the second collar portion 23 when the coil bobbin 11 is insert-molded.
　第２コネクタ部１３は、軸方向から見て第１コネクタ部１２と内外方向、即ち胴部２１の半径方向にずらして配置されている。即ち、第２コネクタ部１３は、軸方向から見て第１コネクタ部１２の一部分と重なり、且つ互いの軸線が半径方向にずれて配置されている。それ故、第２コネクタ部１３の挿通孔１３ａもまた半径方向において第１コネクタ部１２の挿通孔１２ａと異なる位置に配置されている。第２コネクタ部１３は、本実施形態において雌型のコネクタであって、第２コネクタ部１３の軸方向他端部側から挿通孔１３ａに雄型のコネクタである機器用コネクタの端子が挿入される。 The second connector part 13 is displaced from the first connector part 12 in the inner and outer directions, that is, in the radial direction of the body part 21 when viewed from the axial direction. That is, the second connector portion 13 overlaps with a portion of the first connector portion 12 when viewed in the axial direction, and the axes are radially shifted from each other.

　図４に示す通電部材１４は、第１コネクタ部１２及び第２コネクタ部１３に架け渡すように設けられている。そして、通電部材１４の端部は、第１コネクタ部１２及び第２コネクタ部１３において端子１４ａ，１４ｂを成している。通電部材１４は胴部２１において埋設されており、胴部２１において軸方向に延在している。更に詳細に説明すると、通電部材１４の中間部分１４ｃ（後述する中間部分２５ａに相当）は、胴部２１において半径方向内側と外側とから保護部材３２によって挟まれている。より詳細に説明すると、通電部材１４の中間部分１４ｃは、半径方向内側及び外側から保護シート４１，４２によって夫々覆われて挟まれている。これにより、通電部材１４が保護部材３２に保護されている。このように通電部材１４を保護部材３２で挟んで保護しておくことによって、通電部材１４に発生する荷重によって通電部材１４が曲がることが抑制できる。 [Current-carrying parts]
The conducting member 14 shown in FIG. 4 is provided so as to span the first connector portion 12 and the second connector portion 13 . The end portions of the conducting member 14 form terminals 14a and 14b in the first connector portion 12 and the second connector portion 13, respectively. The conducting member 14 is embedded in the body portion 21 and extends in the body portion 21 in the axial direction. More specifically, an intermediate portion 14c (corresponding to an intermediate portion 25a, which will be described later) of the current-carrying member 14 is sandwiched between protective members 32 in the body portion 21 from radially inside and outside. More specifically, the intermediate portion 14c of the current-carrying member 14 is covered and sandwiched by protective sheets 41 and 42 from radially inside and outside, respectively. Thereby, the conducting member 14 is protected by the protective member 32 . By sandwiching and protecting the conducting member 14 between the protective members 32 in this way, it is possible to suppress the bending of the conducting member 14 due to the load generated in the conducting member 14 .
　更に詳細に説明すると、通電部材１４は、少なくとも２つの通電芯金２５を有している。通電部材１４は、本実施形態において２つの通電芯金２５を有している。なお、通電部材１４は、必ずしも複数の通電芯金２５である必要はなく、通電可能なプリント基板等であってもよい。即ち、通電部材１４は、両端部に端子１４ａ，１４ｂを有し、それらの端子１４ａ，１４ｂに通電可能な部材であればよい。 In more detail, the current-carrying member 14 has at least two current-carrying cores 25 . The conducting member 14 has two conducting cores 25 in this embodiment. It should be noted that the current-carrying member 14 does not necessarily have to be a plurality of current-carrying cores 25, and may be a conductive printed circuit board or the like. That is, the current-carrying member 14 has terminals 14a and 14b at both ends, and any member that can conduct electricity to the terminals 14a and 14b may be used.
　通電芯金２５は、胴部２１において軸方向に延在するように配置される線材である。通電芯金２５の一端部は、第１コネクタ部１２において第１端子１４ａを成している。そして、２つの通電芯金２５において第１端子１４ａの各々は、第１コネクタ部１２の各挿通孔１２ａに挿通されている。それ故、通電芯金２５の第１端子１４ａは、第１コネクタ部１２において第１端子間距離αをあけて配置されている（図７参照）。なお、第１端子間距離αは、第１端子１４ａの軸間距離である。また、本実施形態において、第１端子１４ａの各々の先端部分は、挿入孔１２ｂへと突き出ている。なお、挿入孔１２ｂには、例えば電子部品又は部品用コネクタが挿入される。そして、第１端子１４ａが電子部品又は部品用コネクタの挿通孔に挿入される。これにより、第１コネクタ部１２と電子部品又は部品用コネクタとが接続される。 The current-carrying core 25 is a wire arranged so as to extend in the axial direction in the body portion 21 . One end of the conductive core 25 forms a first terminal 14 a in the first connector portion 12 . Each of the first terminals 14 a of the two conductive cores 25 is inserted into each insertion hole 12 a of the first connector portion 12 . Therefore, the first terminals 14a of the conductive core 25 are arranged with a first terminal-to-terminal distance α in the first connector portion 12 (see FIG. 7). The distance α between the first terminals is the distance between the axes of the first terminals 14a. Further, in the present embodiment, the tip portion of each first terminal 14a protrudes into the insertion hole 12b. For example, an electronic component or a component connector is inserted into the insertion hole 12b. Then, the first terminal 14a is inserted into the insertion hole of the electronic component or component connector. As a result, the first connector portion 12 and the electronic component or component connector are connected.
　また、通電芯金２５の他端部は、第２コネクタ部１３において第２端子１４ｂを成している。そして、２つの通電芯金２５において第２端子１４ｂの各々は、第２コネクタ部１３の各挿通孔１３ａに挿通されている。それ故、通電芯金２５の第２端子１４ｂは、第２コネクタ部１３において、第２端子間距離βをあけて配置されている。そして、第１端子間距離α及び第２端子間距離βは、互いに異なっている。なお、第２端子間距離βは、第２端子１４ｂの軸間距離である。第２端子１４ｂは、挿通孔１３ａに挿通される機器用コネクタの端子と付き合わされる。これにより、第２コネクタ部１３と機器用コネクタとが接続される。 In addition, the other end of the conductive core 25 forms a second terminal 14b in the second connector portion 13. Each of the second terminals 14 b of the two current-carrying cores 25 is inserted into each insertion hole 13 a of the second connector portion 13 . Therefore, the second terminals 14b of the conductive core 25 are arranged at the second connector portion 13 with a second inter-terminal distance β. The first inter-terminal distance α and the second inter-terminal distance β are different from each other. The distance β between the second terminals is the distance between the axes of the second terminals 14b. The second terminal 14b is mated with a device connector terminal that is inserted through the insertion hole 13a. Thereby, the second connector portion 13 and the device connector are connected.
　また、通電芯金２５の第１端子１４ａ及び第２端子１４ｂは、図８に示すように中間部分２５ａからの半径方向の距離が互いに異なっている。更に詳細に説明すると、通電芯金２５は、Ω字状に形成されている。そして、中間部分２５ａは、直線状に形成されている。そして、通電芯金２５の両端部にある第１端子１４ａ及び第２端子１４ｂもまた直線状に形成され、且つ中間部分２５ａに平行に形成されている。また、中間部分２５ａと各端子１４ａ，１４ｂとは、連結部分２５ｂ、２５ｃとで連結されている。そして、連結部分２５ｂ，２５ｃにおいて半径方向の長さ、即ち高さＨ１，Ｈ２が互いに異なっている。それ故、２つの通電芯金２５は、軸方向に見てＶ字に配置されると第１端子間距離α及び第２端子間距離βを互いに異ならせることができる。そして、２つの通電芯金２５では、端子１４ａ，１４ｂ同士が互いに離れる方向に中間部分２５ａを軸線回りに回動させることによって、第１端子間距離α及び第２端子間距離βを変えることができる。また、第１コネクタ部１２及び第２コネクタ部１３の位置は、前述の通り、胴部２１の半径方向において互いに異なる位置に配置されている。より詳しく説明すると、第１コネクタ部１２の挿通孔１２ａ及び前記第２コネクタ部１３の挿通孔１３ａ位置が胴部２１の半径方向において互いに異なる位置に配置されている。それ故、連結部分２５ｂ，２５ｃの高さＨ１，Ｈ２を各挿通孔１２ａ，１３ａの位置に応じた高さに設定すると、通電芯金２５の中間部分２５ａを回動させることによって端子間距離α及びβを容易に変えることができる。 In addition, the first terminal 14a and the second terminal 14b of the current-carrying core 25 are different in radial distance from the intermediate portion 25a as shown in FIG. More specifically, the current-carrying core 25 is formed in an Ω shape. The intermediate portion 25a is formed linearly. The first terminal 14a and the second terminal 14b at both ends of the conductive core 25 are also formed linearly and parallel to the intermediate portion 25a. Further, the intermediate portion 25a and the respective terminals 14a, 14b are connected by connecting portions 25b, 25c. The lengths in the radial direction, that is, the heights H1 and H2 of the connecting portions 25b and 25c are different from each other. Therefore, when the two current-carrying cores 25 are arranged in a V shape when viewed in the axial direction, the first inter-terminal distance α and the second inter-terminal distance β can be made different from each other. In the two current-carrying cores 25, the first inter-terminal distance α and the second inter-terminal distance β can be changed by rotating the intermediate portion 25a about the axis in the direction in which the terminals 14a and 14b are separated from each other. can. Moreover, the positions of the first connector portion 12 and the second connector portion 13 are arranged at different positions in the radial direction of the trunk portion 21 as described above. More specifically, the insertion hole 12a of the first connector portion 12 and the insertion hole 13a of the second connector portion 13 are arranged at different positions in the radial direction of the trunk portion 21 . Therefore, when the heights H1 and H2 of the connecting portions 25b and 25c are set to the heights corresponding to the positions of the insertion holes 12a and 13a, the intermediate portion 25a of the conductive core 25 is rotated to increase the inter-terminal distance α. and β can be easily changed.
　このように構成されている通電芯金２５は、中間部分２５ａが胴部２１に埋設されている。更に詳細に説明すると、通電芯金２５は、胴部２１において保護部材３２に対応する位置に配置されている。そして、通電芯金２５の中間部分２５ａが胴部２１の内側と外側から保護部材３２によって挟まれている。より詳細に説明すると、通電芯金２５の中間部分２５ａは、図４に示すように紙面に直交する方向の両側（胴部２１においてその内側及び外側）から保護シート４１，４２が夫々被せられている。この際、中間部分２５ａの各々は、保護シート４１の各配線用溝４１ａ及び保護シート４２の各配線用溝４２ａに配置される。そうすると、中間部分２５ａは、各配線用溝４１ａ及び４２ａによって形成される配線用通路３２ａ，３２ｂに夫々挿通される。これにより、中間部分２５ａは、保護シート４１、４２によって形成される保護部材３２に挟まれる。そして、中間部分２５ａが保護部材３２によって保護される。 The conductive core bar 25 configured in this way has an intermediate portion 25 a embedded in the body portion 21 . More specifically, the conductive core 25 is arranged at a position corresponding to the protective member 32 in the body portion 21 . An intermediate portion 25 a of the conductive core 25 is sandwiched between protective members 32 from the inside and outside of the trunk portion 21 . More specifically, as shown in FIG. 4, the intermediate portion 25a of the core 25 is covered with protective sheets 41 and 42 from both sides (inside and outside of the body portion 21) in the direction perpendicular to the plane of the drawing. there is At this time, each intermediate portion 25 a is arranged in each wiring groove 41 a of the protective sheet 41 and each wiring groove 42 a of the protective sheet 42 . Then, the intermediate portion 25a is inserted into the wiring passages 32a and 32b formed by the wiring grooves 41a and 42a, respectively. As a result, the intermediate portion 25a is sandwiched between the protective members 32 formed by the protective sheets 41 and 42. As shown in FIG. The intermediate portion 25a is protected by the protective member 32. As shown in FIG.

When the coil bobbin 11 is insert-molded with the wiring member 40, the third connector portion 15, the protective member 32, and the like arranged in the mold in this manner, the three connector portions 12, 13, and 15 are integrated and the current is supplied. A coil bobbin 11 in which the member 14 is embedded is molded. The three connector portions 12, 13, 15 and the protective member 32 are made of the same material as the coil bobbin 11 in this embodiment. When the coil wire 20 is wound around the body portion 21 of the coil bobbin 11 to form the coil 10 around the body portion 21 , the coil device 1 is obtained.
　このように作成されるコイル装置１では、通電部材１４が保護部材３２に挟まれて保護されているので、通電部材１４に発生する荷重によって通電部材１４が曲がることが抑制できる。特に、インサート成形によってコイルボビン１１を作成する際、胴部２１を薄肉形成すべく高い流入圧で金型に合成樹脂を流す必要がある。そうすると、通電部材１４が流入樹脂から荷重を受ける。通電部材１４を保護部材３２で挟んで保護しておくことによって、流入樹脂から受ける荷重によって通電部材１４が曲がることが抑制できる。 In the coil device 1 thus produced, the current-carrying member 14 is sandwiched and protected by the protective members 32, so that the current-carrying member 14 can be prevented from bending due to the load generated in the current-carrying member 14. In particular, when the coil bobbin 11 is produced by insert molding, it is necessary to flow the synthetic resin into the mold at a high inflow pressure in order to form the body portion 21 thin. Then, the conducting member 14 receives a load from the inflowing resin. By sandwiching and protecting the conducting member 14 between the protective members 32, the bending of the conducting member 14 due to the load received from the inflowing resin can be suppressed.
　［コイル装置の作用及び効果］
　本実施形態のコイル装置１では、通電部材１４が胴部２１に埋設されているので、通電部材１４を配置する通路をコイルボビン１１に別途形成したり、コイルボビン１１を回避するようにして通電部材１４を配置したりすることを避けることができる。これにより、通電部材１４の取り回しの簡素化をおこなうことができ、その結果コイルボビン１１の小型化、即ちコイル装置１の小型化を図ることができる。 [Action and effect of coil device]
In the coil device 1 of the present embodiment, the current-carrying member 14 is embedded in the body portion 21 . can be avoided. As a result, the coil bobbin 11 can be miniaturized, that is, the coil device 1 can be miniaturized.
　また、コイル装置１では、通電芯金２５の第１端子間距離αと第２端子間距離βが互いに異なるように通電芯金２５が形成されている。それ故、端子間距離α，βを変えるべく、コネクタ部１２，１３以外の別部材を用いる必要がないので、コイル装置１の省スペース化及びコストダウンを図ることができる。また、コイル装置１では、保護部材３２において、切欠き４１ｂ，４２ｂが互い違いに配置されて他方の保護シート４２の切欠き４２ｂから一方の保護シート４１の切欠き４１ｂの間の部分が表出している。それ故、コイルボビン１１を成形する際に切欠き４１ｂ，４２ｂに樹脂を流入することで、胴部本体３１と保護部材３２の一体性を高めることができる。なお、胴部２１は、胴部２１において径方向内方及び外方の少なくとも一方側に保護部材３２が表出する程度に薄肉形成されることがある。その際、保護部材３２は、胴部本体３１においてアウトサート成形される。このような場合であっても、前述するように切欠き４１ｂ，４２ｂに樹脂を流入させることによって胴部本体３１と保護部材３２とを強固に接合させることができる。 In addition, in the coil device 1, the conductive core 25 is formed such that the first terminal-to-terminal distance α and the second terminal-to-terminal distance β of the conductive core 25 are different from each other. Therefore, since there is no need to use a separate member other than the connector portions 12 and 13 to change the inter-terminal distances α and β, space saving and cost reduction of the coil device 1 can be achieved. In the coil device 1, the notches 41b and 42b are alternately arranged in the protective member 32, and the portion between the notch 42b of the other protective sheet 42 and the notch 41b of the one protective sheet 41 is exposed. there is Therefore, by flowing resin into the notches 41b and 42b when molding the coil bobbin 11, the integration between the trunk main body 31 and the protective member 32 can be enhanced. In addition, the trunk portion 21 may be formed so thin that the protective member 32 is exposed on at least one side of the radially inner side and the outer side of the trunk portion 21 . At that time, the protective member 32 is outsert-molded in the trunk body 31 . Even in such a case, the trunk main body 31 and the protective member 32 can be firmly joined by flowing the resin into the notches 41b and 42b as described above.
　また、コイル装置１では、コネクタ部１２，１３が各鍔部２２，２３に一体的に夫々設けられている。これにより、コイルボビン１１又はコネクタ部１２，１３に振動及び衝撃が作用した際に、コイルボビン１１とコネクタ部１２，１３とが別々に動いて通電部材１４が破断したり、またコイルボビン１１からコネクタ部１２，１３が抜けたりすることを抑制できる。但し、各鍔部２２，２３とコネクタ部１２，１３とは、必ずしも一体化されている必要はない。例えば、コネクタ部１２，１３は、各鍔部２２，２３に挿通されるようにして設けられてもよい。 Also, in the coil device 1, the connector portions 12 and 13 are provided integrally with the flange portions 22 and 23, respectively. As a result, when the coil bobbin 11 or the connector portions 12 and 13 are subjected to vibration and impact, the coil bobbin 11 and the connector portions 12 and 13 move separately, causing the current-carrying member 14 to break, or the coil bobbin 11 to the connector portion 12 to break. , 13 can be suppressed. However, the flanges 22, 23 and the connector parts 12, 13 do not necessarily have to be integrated. For example, the connector portions 12 and 13 may be provided so as to be inserted through the respective collar portions 22 and 23 .
　更に、コイル装置１では、コネクタ部１２，１３が各鍔部２２，２３に一体的に夫々設けられている。それ故、成形後に機器用コネクタ及び電子部品（又は部品用コネクタ）を各コネクタ部１２，１３に取り付けることで電子機器と電子部品とを電気的に接続することができる。それ故、コイル装置１の通電部材１４と電子機器及び電子部品とを接続する作業が容易であり、コイル装置１を適用した製品の組立作業性が向上する。 Furthermore, in the coil device 1, the connector portions 12 and 13 are provided integrally with the flange portions 22 and 23, respectively. Therefore, by attaching the device connector and the electronic component (or the component connector) to the respective connector portions 12 and 13 after molding, the electronic device and the electronic component can be electrically connected. Therefore, the operation of connecting the current-carrying member 14 of the coil device 1 to the electronic equipment and electronic components is facilitated, and the assembling workability of the product to which the coil device 1 is applied is improved.
　＜電磁弁＞
　以下では、本実施形態のコイル装置１が適用された製品の一例である、図９に示すような電磁弁２について説明する。なお、電磁弁２の構成については、前述する各実施形態の構成に対応する構成である場合、対応する構成と同一の符号を付し、その詳しい説明は省略する。 <Solenoid valve>
A solenoid valve 2 as shown in FIG. 9, which is an example of a product to which the coil device 1 of the present embodiment is applied, will be described below. Regarding the configuration of the solenoid valve 2, when the configuration corresponds to the configuration of each of the above-described embodiments, the same reference numerals as those of the corresponding configuration are attached, and detailed description thereof will be omitted.
　電磁弁２は、例えばタンクバルブ装置３に備わっている。そして、タンクバルブ装置３は、圧力タンク、例えば高圧タンク（以下、単に「タンク」という）４に設けられている。タンク４は、流体を貯留することができる。本実施形態において流体はガスである。例えば、ガスは水素及びＣＮＧである。タンクバルブ装置３は、タンク４の口部４ａを封止している。そして、タンクバルブ装置３は、電磁弁２によってタンク４からガスを送出し、またガスの送出を止めることができる。 The solenoid valve 2 is provided in the tank valve device 3, for example. The tank valve device 3 is provided in a pressure tank, for example, a high pressure tank (hereinafter simply referred to as “tank”) 4 . The tank 4 can store fluid. In this embodiment the fluid is gas. For example, the gases are hydrogen and CNG. The tank valve device 3 seals the opening 4 a of the tank 4 . Then, the tank valve device 3 can send gas from the tank 4 by means of the solenoid valve 2 and stop the gas sending.
　また、電磁弁２は、コイル装置１と、主弁体６１と、シートピストン６２と、プランジャ６３と、固定磁極６４と、を有している。そして、電磁弁２は、コイル装置１のコイル１０に通電することによって流路５１の開度を調整する。 Also, the solenoid valve 2 has a coil device 1, a main valve body 61, a seat piston 62, a plunger 63, and a fixed magnetic pole 64. The electromagnetic valve 2 adjusts the opening of the flow path 51 by energizing the coil 10 of the coil device 1 .
　コイル装置１は、第１鍔部２２をタンク４の底側に向け且つ第２鍔部２３をタンク４の開口側に向けるようにして配置されている。そして、第１コネクタ部１２に温度センサ５２が接続され、第２コネクタ部１３に機器用配線５３の機器用コネクタ５３ａが接続されている。そして、機器用配線５３が電子機器に接続されている。これにより、温度センサ５２が配線部材４０を介して電子機器に接続されている。また、第３コネクタ部１５にコイル用配線５４のコイル用コネクタ５４ａが接続されている。そして、コイル装置１には、コイル用配線５４を介してコイル線２０に電力が供給される。なお、説明の便宜上、図９では第２コネクタ部１３と第３コネクタ部１５とが１８０度ずれた位置に配置されているが、２つのコネクタ部１３，１５は必ずしもこのような相対位置に配置されている必要はない。即ち、第２コネクタ部１３と第３コネクタ部１５とが、図１のように鋭角な角度にずらして配置されていてもよい。 The coil device 1 is arranged so that the first flange portion 22 faces the bottom side of the tank 4 and the second flange portion 23 faces the opening side of the tank 4 . A temperature sensor 52 is connected to the first connector portion 12 , and a device connector 53 a of a device wiring 53 is connected to the second connector portion 13 . The device wiring 53 is connected to the electronic device. Thereby, the temperature sensor 52 is connected to the electronic device via the wiring member 40 . A coil connector 54 a of a coil wire 54 is connected to the third connector portion 15 . Electric power is supplied to the coil wire 20 of the coil device 1 via the coil wire 54 . For convenience of explanation, the second connector portion 13 and the third connector portion 15 are arranged at positions shifted by 180 degrees in FIG. It doesn't have to be. That is, the second connector portion 13 and the third connector portion 15 may be arranged at an acute angle as shown in FIG.
　このように構成されている電磁弁２は、コイル用配線５４を介してコイル１０に通電することによってプランジャ６３が固定磁極６４に吸着される。そうすると、プランジャ６３を介してシートピストン６２が動く。これにより、主弁体６１のパイロット通路６１ａが開いて主弁体６１が流路５１を開く。そうするとタンク４の流体が送出する。他方、コイル１０の通電を止めると、シートピストン６２が主弁体６１を押すことによって流路５１を閉じる。これにより、流路５１が閉じられてタンク４からの流体の送出が止まる。また、電磁弁２では、配線部材４０及び機器用配線５３を介して温度センサ５２から機器用配線５３に信号が送られる。更に、これにより、電子機器がタンク４内の温度を検出することができる。 In the solenoid valve 2 configured in this manner, the plunger 63 is attracted to the fixed magnetic pole 64 by energizing the coil 10 through the coil wiring 54 . Then, the seat piston 62 moves via the plunger 63 . As a result, the pilot passage 61 a of the main valve body 61 opens and the main valve body 61 opens the flow path 51 . The fluid in the tank 4 is then delivered. On the other hand, when the coil 10 is de-energized, the seat piston 62 pushes the main valve body 61 to close the flow path 51 . As a result, the channel 51 is closed and the delivery of fluid from the tank 4 is stopped. In the electromagnetic valve 2 , a signal is sent from the temperature sensor 52 to the device wiring 53 via the wiring member 40 and the device wiring 53 . Furthermore, this allows the electronics to detect the temperature in the tank 4 .
