Note that, in a plurality of embodiments, substantially the same components are denoted by the same reference numerals, and description thereof is omitted.
　（第一実施形態）
　第一実施形態による位置検出装置を図１～３を参照して説明する。第一実施形態による「位置検出装置」としての回転角検出装置１は、図示しない車両が搭載するエンジンへの吸気量を制御する電子制御スロットル装置８０に用いられる。 (First embodiment)
A position detection apparatus according to the first embodiment will be described with reference to FIGS. The rotation angle detection device 1 as a “position detection device” according to the first embodiment is used in an electronically controlled throttle device 80 that controls an intake air amount to an engine mounted on a vehicle (not shown).
　最初に、電子制御スロットル装置８０の構成を説明する。電子制御スロットル装置８０は、図１に示すように、バルブハウジング８１、スロットルバルブ８２、モータ８３、回転角検出装置１、電子制御ユニット（以下、「ＥＣＵ」という）８４などを備えている。 First, the configuration of the electronic control throttle device 80 will be described. As shown in FIG. 1, the electronic control throttle device 80 includes a valve housing 81, a throttle valve 82, a motor 83, a rotation angle detection device 1, an electronic control unit (hereinafter referred to as “ECU”) 84, and the like.
　バルブハウジング８１は、エンジンに空気を導入する吸気通路８１０を有する。吸気通路８１０にはスロットルバルブ８２が設けられている。 The valve housing 81 has an intake passage 810 for introducing air into the engine. A throttle valve 82 is provided in the intake passage 810.
　スロットルバルブ８２は、「検出対象」としての弁部材８２１、および、バルブシャフト８２２を有する。
　弁部材８２１は、吸気通路８１０の内径よりわずかに小さい外径を有する略円板状の部材である。弁部材８２１は、バルブシャフト８２２に固定されている。
　バルブシャフト８２２の両側は、バルブハウジング８１に回転可能に軸受けされている。これにより、弁部材８２１は、バルブシャフト８２２の回転軸ＣＡ１を回転軸として回転可能である。バルブシャフト８２２の回転角検出装置１側の端部には磁石８２３が設けられている。バルブシャフト８２２が回転すると、回転角検出装置１が備えるＩＣパッケージ１０近傍の磁界が変化する。 The throttle valve 82 includes a valve member 821 as a “detection target” and a valve shaft 822.
The valve member 821 is a substantially disk-shaped member having an outer diameter slightly smaller than the inner diameter of the intake passage 810. The valve member 821 is fixed to the valve shaft 822.
Both sides of the valve shaft 822 are rotatably supported by the valve housing 81. As a result, the valve member 821 can rotate about the rotation axis CA1 of the valve shaft 822 as the rotation axis. A magnet 823 is provided at the end of the valve shaft 822 on the rotation angle detection device 1 side. When the valve shaft 822 rotates, the magnetic field in the vicinity of the IC package 10 included in the rotation angle detection device 1 changes.
　モータ８３は、回転角検出装置１に収容されている。モータ８３は、連結部材８３１を介してバルブシャフト８２２と連結している。モータ８３は、バルブシャフト８２２を回転可能な回転トルクを発生する。モータ８３は、ＥＣＵ８４と電気的に接続している。 The motor 83 is accommodated in the rotation angle detection device 1. The motor 83 is connected to the valve shaft 822 via a connecting member 831. The motor 83 generates a rotational torque that can rotate the valve shaft 822. The motor 83 is electrically connected to the ECU 84.
　ＥＣＵ８４は、演算手段としてのＣＰＵ、記憶手段としてのＲＯＭおよびＲＡＭ、ならびに、入出力手段等を有する小型のコンピュータである。ＥＣＵ８４は、電子制御スロットル装置８０を搭載する車両の走行状況や、当該車両の運転者の操作状況に応じてスロットルバルブ８２の開度を決定する。ＥＣＵ８４は、スロットルバルブ８２の開度に応じた電力をモータ８３に出力する。これにより、スロットルバルブ８２の開度が制御され、エンジンに供給される吸気量が調節される。 The ECU 84 is a small computer having a CPU as calculation means, ROM and RAM as storage means, and input / output means. The ECU 84 determines the opening degree of the throttle valve 82 according to the traveling state of the vehicle on which the electronic control throttle device 80 is mounted and the operation state of the driver of the vehicle.

　センサハウジング３０は、略直方体状に形成されている中空の部材である。センサハウジング３０は、図１に示すように、バルブハウジング８１側に開口を有し、内部にモータ８３を収容可能に形成されている。センサハウジング３０は、ボルト３０１によってバルブハウジング８１に相対移動不能に固定されている。センサハウジング３０は、ＩＣパッケージ１０を搭載可能なステージ３２を有する。これにより、ＩＣパッケージ１０は、図１に示すように、磁石８２３の近傍に設けられる。ステージ３２には、センサターミナル２０の一部がインサートされている。 The sensor housing 30 is a hollow member formed in a substantially rectangular parallelepiped shape. As shown in FIG. 1, the sensor housing 30 has an opening on the valve housing 81 side, and is formed so that a motor 83 can be accommodated therein. The sensor housing 30 is fixed to the valve housing 81 by a bolt 301 so as not to be relatively movable. The sensor housing 30 has a stage 32 on which the IC package 10 can be mounted. Thereby, the IC package 10 is provided in the vicinity of the magnet 823, as shown in FIG. A part of the sensor terminal 20 is inserted into the stage 32.
　次に、第一実施形態による回転角検出装置１の特徴について図３を参照して説明する。
　ＩＣパッケージ１０の端面１３１からｘ軸のマイナス方向に突出する四本のリード線は長さが異なっている。具体的には、図３に示すように、第一信号リード線１７の長さは、電源リード線１６に比べ長い。また、グランドリード線１９は、電源リード線１６および第二信号リード線１８に比べ長い。すなわち、四本のリード線のうち一のリード線の長さは、当該一のリード線に隣り合う他のリード線の長さと異なっている。なお、第一実施形態では、第一信号リード線１７の長さとグランドリード線１９の長さとは同じになっている。また、電源リード線１６の長さと第二信号リード線１８の長さとは同じになっている。 Next, features of the rotation angle detection device 1 according to the first embodiment will be described with reference to FIG.
The lengths of the four lead wires protruding from the end surface 131 of the IC package 10 in the negative direction of the x-axis are different. Specifically, as shown in FIG. 3, the length of the first signal lead wire 17 is longer than that of the power supply lead wire 16. The ground lead wire 19 is longer than the power supply lead wire 16 and the second signal lead wire 18. That is, the length of one of the four lead wires is different from the length of another lead wire adjacent to the one lead wire. In the first embodiment, the length of the first signal lead wire 17 and the length of the ground lead wire 19 are the same. The length of the power supply lead 16 and the length of the second signal lead 18 are the same.
　四本のリード線がこのような関係にあるため、例えば、電源リード線１６と電源溶接端子２１１とが溶接される「第一溶接部」としての溶接部１６１の中央Ｃ１６から端面１３１までの距離Ｌ１は、第一信号リード線１７と第一信号溶接端子２２１とが溶接される「第二溶接部」としての溶接部１７１の中央Ｃ１７から端面１３１までの距離Ｌ２に比べ短い。また、溶接部１６１の中央Ｃ１６から端面１３１までの距離Ｌ１と、グランドリード線１９とグランド溶接端子２４１とが溶接される「第二溶接部」としての溶接部１９１の中央Ｃ１９から端面１３１までの距離Ｌ２との関係も同様である。また、第二信号リード線１８と第二信号溶接端子２３１とが溶接される溶接部１８１の中央Ｃ１８から端面１３１までの距離Ｌ１と、溶接部１９１の中央Ｃ１９から端面１３１までの距離Ｌ２との関係も同様である。 Since the four lead wires have such a relationship, for example, the distance from the center C16 of the welded portion 161 to the end face 131 as the “first welded portion” where the power supply lead wire 16 and the power supply welding terminal 211 are welded. L1 is shorter than the distance L2 from the center C17 to the end face 131 of the welded portion 171 as the “second welded portion” where the first signal lead wire 17 and the first signal welding terminal 221 are welded. Further, the distance L1 from the center C16 of the welded portion 161 to the end face 131 and the center C19 of the welded portion 191 to the end face 131 as the “second welded portion” where the ground lead wire 19 and the ground weld terminal 241 are welded. The relationship with the distance L2 is the same. Further, a distance L1 from the center C18 of the welded portion 181 to which the second signal lead wire 18 and the second signal welding terminal 231 are welded to the end surface 131, and a distance L2 from the center C19 of the welded portion 191 to the end surface 131. The relationship is similar.
　すなわち、溶接部１６１は、溶接部１７１を通り中心軸ＣＡ１７に垂直な垂直線ＶＬ１７上、および、溶接部１９１を通り中心軸ＣＡ１９に垂直な垂直線ＶＬ１９上とは異なる場所に位置する。具体的には、溶接部１６１は、中心軸ＣＡ１６に隣り合う中心軸を有する溶接部１７１および溶接部１９１に対してずれた場所に位置している。また、溶接部１８１は、溶接部１９１を通り中心軸ＣＡ１９に垂直な垂直線ＶＬ１９上とは異なる場所に位置する。具体的には、溶接部１８１は、中心軸ＣＡ１８に隣り合う中心軸を有する溶接部１９１に対してずれた場所に位置している。 That is, the welded portion 161 is located on a vertical line VL17 that passes through the welded portion 171 and is perpendicular to the central axis CA17 and on a vertical line VL19 that passes through the welded portion 191 and is perpendicular to the central axis CA19. Specifically, the welded portion 161 is located at a location shifted from the welded portion 171 and the welded portion 191 having the central axis adjacent to the central axis CA16. Further, the welded portion 181 is located at a different location from the vertical line VL19 that passes through the welded portion 191 and is perpendicular to the central axis CA19. Specifically, the welded portion 181 is located at a location displaced from the welded portion 191 having a central axis adjacent to the central axis CA18.
　また、四本のターミナル線のそれぞれが有する溶接端子をｘ軸に沿う方向で見ると、電源溶接端子２１１および第二信号溶接端子２３１と、第一信号溶接端子２２１およびグランド溶接端子２４１とは、ずれた位置に設けられている。
　具体的には、図３に示すように、電源溶接端子２１１および第二信号溶接端子２３１が位置するｘ軸に沿う方向の領域Ａ１と、第一信号溶接端子２２１およびグランド溶接端子２４１が位置するｘ軸に沿う方向の領域Ａ２とは、重なっていない。 Further, when the welding terminals of each of the four terminal wires are viewed in the direction along the x axis, the power welding terminal 211 and the second signal welding terminal 231, the first signal welding terminal 221 and the ground welding terminal 241 are: It is provided at a shifted position.
Specifically, as shown in FIG. 3, a region A1 in the direction along the x axis where the power welding terminal 211 and the second signal welding terminal 231 are located, and the first signal welding terminal 221 and the ground welding terminal 241 are located. It does not overlap with the region A2 in the direction along the x-axis.
　第一実施形態による回転角検出装置１では、ＩＣパッケージ１０は、四本のリード線を有している。四本のリード線は、それぞれ対応するターミナル線に溶接される。図３に示すように、四本のリード線とそれぞれに対応するターミナル線とが溶接される箇所は、互い違いにずれている。 In the rotation angle detection device 1 according to the first embodiment, the IC package 10 has four lead wires. Each of the four lead wires is welded to a corresponding terminal wire. As shown in FIG. 3, the locations where the four lead wires and the corresponding terminal wires are welded are staggered.
　また、第一信号接続部２２２のｙ軸方向の幅およびグランド接続部２４２のｙ軸方向の幅は、電源溶接端子２１１のｙ軸方向の幅に比べ狭くなっている。これにより、第一信号接続部２２２のｙ軸方向の幅およびグランド接続部２４２のｙ軸方向の幅と電源溶接端子２１１のｙ軸方向の幅とが同じ場合に比べて、電源溶接端子２１１の周囲に絶縁のための空間が比較的大きく確保することができる。また、グランド接続部２４２のｙ軸方向の幅は、第二信号溶接端子２３１のｙ軸方向の幅に比べ狭くなっている。これにより、グランド接続部２４２のｙ軸方向の幅と第二信号溶接端子２３１のｙ軸方向の幅とが同じ場合に比べ、第二信号溶接端子２３１の周囲に絶縁のための空間が比較的大きく確保することができる。 Also, the width of the first signal connecting portion 222 in the y-axis direction and the width of the ground connecting portion 242 in the y-axis direction are narrower than the width of the power welding terminal 211 in the y-axis direction. Thereby, compared with the case where the width | variety of the y-axis direction of the 1st signal connection part 222 and the y-axis direction of the ground connection part 242 and the width | variety of the y-axis direction of the power welding terminal 211 are the same, the power welding terminal 211 of FIG. A relatively large space for insulation can be secured around the periphery. Further, the width of the ground connection portion 242 in the y-axis direction is narrower than the width of the second signal welding terminal 231 in the y-axis direction. Thereby, compared with the case where the width in the y-axis direction of the ground connection portion 242 and the width in the y-axis direction of the second signal welding terminal 231 are the same, a space for insulation is relatively around the second signal welding terminal 231. It can be secured greatly.
　例えば、電源リード線１６と電源ターミナル線２１とを溶接するときに発生し周囲に飛散するスパッタが、第一信号リード線１７、グランドリード線１９、第一信号ターミナル線２２、グランドターミナル線２４、および、溶接部１７１，１９１が付着しにくくなる。したがって、電源リード線１６および電源ターミナル線２１と、第一信号リード線１７および第一信号ターミナル線２２、ならびに、グランドリード線１９およびグランドターミナル線２４との短絡を防止することができる。この関係は、グランドリード線１９およびグランドターミナル線２４と、電源リード線１６および電源ターミナル線２１、または、第二信号リード線１８および第二信号ターミナル線２３とにおいても同様である。
　第一実施形態による回転角検出装置１では、このようにして、溶接時に発生するスパッタが意図しない箇所に付着することを防止することができる。これにより、異なるリード線とターミナル線との組み合わせが短絡することを防止できる。 For example, spatter that occurs when the power supply lead wire 16 and the power supply terminal wire 21 are welded and scatters around the first signal lead wire 17, the ground lead wire 19, the first signal terminal wire 22, the ground terminal wire 24, And it becomes difficult for the welding parts 171 and 191 to adhere. Therefore, it is possible to prevent a short circuit between the power supply lead wire 16 and the power supply terminal wire 21, the first signal lead wire 17 and the first signal terminal wire 22, and the ground lead wire 19 and the ground terminal wire 24. This relationship also applies to the ground lead wire 19 and the ground terminal wire 24, the power supply lead wire 16 and the power supply terminal wire 21, or the second signal lead wire 18 and the second signal terminal wire 23.
In this way, the rotation angle detection device 1 according to the first embodiment can prevent spatter generated during welding from adhering to an unintended location. Thereby, it can prevent that the combination of a different lead wire and a terminal wire short-circuits.
　また、第一実施形態による回転角検出装置１では、ｘ軸に沿う方向において、電源溶接端子２１１および第二信号溶接端子２３１は、領域Ａ１に形成され、第一信号溶接端子２２１およびグランド溶接端子２４１は、領域Ａ２に形成されている。すなわち、第一信号溶接端子２２１、電源溶接端子２１１、グランド溶接端子２４１、および、第二信号溶接端子２３１は、隣り合わないよう設けられている。これにより、一のリード線と一のターミナル線とを溶接する箇所と、当該一のリード線に隣り合う他のリード線と当該他のリード線と溶接される他のターミナル線とを溶接する箇所とが確実にずれた場所に位置する。したがって、溶接時に発生するスパッタによって異なるリード線とターミナル線との組み合わせが短絡することを確実に防止できる。 In the rotation angle detection device 1 according to the first embodiment, the power welding terminal 211 and the second signal welding terminal 231 are formed in the region A1 in the direction along the x axis, and the first signal welding terminal 221 and the ground welding terminal are formed. 241 is formed in region A2. That is, the first signal welding terminal 221, the power welding terminal 211, the ground welding terminal 241, and the second signal welding terminal 231 are provided so as not to be adjacent to each other. Thereby, a location where one lead wire and one terminal wire are welded, and another lead wire adjacent to the one lead wire and another terminal wire welded to the other lead wire It is located in a location where it is definitely displaced. Therefore, it is possible to reliably prevent the combination of different lead wires and terminal wires from being short-circuited due to spatter generated during welding.
