Conventionally, there has been known a position detection device that can detect a position of a detection target that moves relative to a reference member using magnetic flux generation means such as a magnet. For example, Patent Document 1 discloses an IC package having two magnetic detection elements that can detect a change in a magnetic field accompanying rotation of a detection target, a sensor terminal that can be electrically connected to the IC package, and a rotation that can rotate the detection target.

Thereby, the rotation angle detection apparatus 1 is completed.
次に、回転角検出装置1の効果について、図4A及び図4Bに基づいて説明する。
(A)図4Aには、第一実施形態による回転角検出装置1における第一リード線16、グランドリード線17、電源リード線18、及び、第二リード線19と、第一ターミナル線21、グランドターミナル線22、電源ターミナル線23、及び、第二ターミナル線24との位置関係を示す。また、図4Bには、比較例の回転角検出装置90における第一リード線96、グランドリード線97、電源リード線98、及び、第二リード線99と、第一ターミナル線91、グランドターミナル線92、電源ターミナル線93、及び、第二ターミナル線94との位置関係を示す。ここで、比較例の回転角検出装置90では、回転角検出装置1とは異なり、グランドターミナル線92のグランドリード線97に溶接される部位は、x軸のプラス方向に延びるよう形成されている。 Next, the effect of the rotation angle detection device 1 will be described with reference to FIGS. 4A and 4B.
(A) In FIG. 4A, thefirst lead wire 16, the ground lead wire 17, the power supply lead wire 18, the second lead wire 19, and the first terminal wire 21 in the rotation angle detection device 1 according to the first embodiment, The positional relationship with the ground terminal line 22, the power supply terminal line 23, and the 2nd terminal line 24 is shown. 4B shows the first lead wire 96, the ground lead wire 97, the power supply lead wire 98, the second lead wire 99, the first terminal wire 91, and the ground terminal wire in the rotation angle detecting device 90 of the comparative example. 92 shows the positional relationship with the power source terminal line 93 and the second terminal line 94. Here, in the rotation angle detection device 90 of the comparative example, unlike the rotation angle detection device 1, the portion welded to the ground lead wire 97 of the ground terminal wire 92 is formed to extend in the positive direction of the x axis. .
(A)図4Aには、第一実施形態による回転角検出装置1における第一リード線16、グランドリード線17、電源リード線18、及び、第二リード線19と、第一ターミナル線21、グランドターミナル線22、電源ターミナル線23、及び、第二ターミナル線24との位置関係を示す。また、図4Bには、比較例の回転角検出装置90における第一リード線96、グランドリード線97、電源リード線98、及び、第二リード線99と、第一ターミナル線91、グランドターミナル線92、電源ターミナル線93、及び、第二ターミナル線94との位置関係を示す。ここで、比較例の回転角検出装置90では、回転角検出装置1とは異なり、グランドターミナル線92のグランドリード線97に溶接される部位は、x軸のプラス方向に延びるよう形成されている。 Next, the effect of the rotation angle detection device 1 will be described with reference to FIGS. 4A and 4B.
(A) In FIG. 4A, the
比較例の回転角検出装置90では、センサターミナル95が電源リード線98などの近傍からコネクタ部901まで延びると、図4Bに示すように、コネクタ部901において第一ターミナル線91、グランドターミナル線92、電源ターミナル線93、第二ターミナル線94の順に並ぶ。このため、回転角検出装置90のモータターミナル902の隣には、第二ターミナル線94が位置することとなるため、比較例の回転角検出装置90では、モータターミナル902と第二ターミナル線94とが短絡するおそれがある。
In the rotation angle detection device 90 of the comparative example, when the sensor terminal 95 extends from the vicinity of the power supply lead wire 98 or the like to the connector portion 901, the first terminal wire 91 and the ground terminal wire 92 are connected to the connector portion 901 as shown in FIG. 4B. The power terminal line 93 and the second terminal line 94 are arranged in this order. For this reason, since the second terminal line 94 is positioned next to the motor terminal 902 of the rotation angle detection device 90, in the rotation angle detection device 90 of the comparative example, the motor terminal 902 and the second terminal line 94 are May short circuit.
一方、第一実施形態による回転角検出装置1では、グランドリード線17に接続するグランドターミナル線22は、第二ターミナル線24からみてグランドターミナル線22とは反対側に位置する迂回用ターミナル線25に接続している。これにより、コネクタ部31において、モータターミナル線28,29のモータコネクタ端子283,293の隣に、グランドターミナル線22と電気的に接続している迂回用ターミナル線25の迂回用端子253が並ぶ。これにより、モータコネクタ端子283,293の隣に第二コネクタ端子243などが並ぶ場合に比べ、コネクタ部31におけるモータターミナル27とセンサターミナル20との短絡を防止することができる。
On the other hand, in the rotation angle detection device 1 according to the first embodiment, the ground terminal wire 22 connected to the ground lead wire 17 is a bypass terminal wire 25 located on the opposite side of the ground terminal wire 22 from the second terminal wire 24. Connected to. Thereby, in the connector part 31, the detour terminals 253 of the detour terminal line 25 electrically connected to the ground terminal line 22 are arranged next to the motor connector terminals 283 and 293 of the motor terminal lines 28 and 29. Thereby, compared with the case where the 2nd connector terminal 243 etc. are located next to the motor connector terminal 283,293, the short circuit with the motor terminal 27 and the sensor terminal 20 in the connector part 31 can be prevented.
(B)また、比較例の回転角検出装置90では、モータターミナル902を流れる電流によって、モータターミナル902の隣の第二ターミナル線94を通る第二信号にノイズが入るおそれがある。このため、スロットルバルブ82の回転角を正確に検出できなくなる。
第一実施形態による回転角検出装置1では、第一ターミナル線21及び第二ターミナル線24は、モータターミナル線28,29から比較的離れた位置に設けられる。これにより、モータターミナル線28,29を流れる電流による磁界に起因して第一信号及び第二信号に入るノイズを低減することができる。したがって、弁部材821の回転角の検出精度を向上することができる。 (B) Further, in the rotationangle detection device 90 of the comparative example, there is a possibility that noise may enter the second signal passing through the second terminal line 94 adjacent to the motor terminal 902 due to the current flowing through the motor terminal 902. For this reason, the rotation angle of the throttle valve 82 cannot be accurately detected.
In the rotation angle detection device 1 according to the first embodiment, the firstterminal line 21 and the second terminal line 24 are provided at positions relatively distant from the motor terminal lines 28 and 29. Thereby, the noise which enters into the 1st signal and the 2nd signal due to the magnetic field by the current which flows through motor terminal lines 28 and 29 can be reduced. Therefore, the detection accuracy of the rotation angle of the valve member 821 can be improved.
第一実施形態による回転角検出装置1では、第一ターミナル線21及び第二ターミナル線24は、モータターミナル線28,29から比較的離れた位置に設けられる。これにより、モータターミナル線28,29を流れる電流による磁界に起因して第一信号及び第二信号に入るノイズを低減することができる。したがって、弁部材821の回転角の検出精度を向上することができる。 (B) Further, in the rotation
In the rotation angle detection device 1 according to the first embodiment, the first
(C)また、第一実施形態による回転角検出装置1では、上述した効果(A)、(B)を奏するために、グランドターミナル線22を第一ターミナル線21、電源ターミナル線23及び第二ターミナル線24に対して回転軸CA1の方向に取り回すことが不要となる。これにより、回転角検出装置1の体格が大きくなることを防止することができる。
(C) Moreover, in the rotation angle detection apparatus 1 according to the first embodiment, the ground terminal line 22 is replaced with the first terminal line 21, the power supply terminal line 23, and the second terminal in order to achieve the effects (A) and (B) described above. It is not necessary to route the terminal wire 24 in the direction of the rotation axis CA1. Thereby, it can prevent that the physique of the rotation angle detection apparatus 1 becomes large.
(D)第一実施形態による回転角検出装置1の製造方法では、センサターミナル20の原型40をセンサターミナル20として利用するとき、ダイバー422と第一溶接端子211となる部位411、ダイバー422と電源溶接端子231となる部位431、及び、ダイバー422と第二溶接端子241となる部位441とを切断する一方、グランド溶接端子221となる部位421及び迂回用ターミナル線25となる部位451に接続されたままのダイバー422をグランドターミナル線22の迂回部222として利用する。これにより、モータターミナル27の隣にグランドターミナル線22と電気的に接続している迂回用ターミナル線25を並べることが可能なコネクタ部31を容易に形成することができる。
(D) In the manufacturing method of the rotation angle detection device 1 according to the first embodiment, when the prototype 40 of the sensor terminal 20 is used as the sensor terminal 20, the diver 422 and the part 411 that becomes the first welding terminal 211, the diver 422 and the power source While cutting the part 431 to be the welding terminal 231 and the part 441 to be the diver 422 and the second welding terminal 241, it was connected to the part 421 to be the ground welding terminal 221 and the part 451 to be the bypass terminal line 25. The remaining diver 422 is used as the bypass unit 222 of the ground terminal line 22. Thereby, the connector part 31 which can arrange | position the detouring terminal wire 25 electrically connected with the ground terminal wire 22 next to the motor terminal 27 can be formed easily.
(第二実施形態)
第二実施形態による位置検出装置を図5に基づき説明する。第二実施形態では、コンデンサを備える点が第一実施形態と異なる。 (Second embodiment)
A position detection apparatus according to the second embodiment will be described with reference to FIG. The second embodiment is different from the first embodiment in that a capacitor is provided.
第二実施形態による位置検出装置を図5に基づき説明する。第二実施形態では、コンデンサを備える点が第一実施形態と異なる。 (Second embodiment)
A position detection apparatus according to the second embodiment will be described with reference to FIG. The second embodiment is different from the first embodiment in that a capacitor is provided.
第二実施形態による回転角検出装置は、ICパッケージ10、センサターミナル20、モータターミナル27、コンデンサ35,36,37、及び、センサハウジング30を有する。
The rotation angle detection device according to the second embodiment includes an IC package 10, a sensor terminal 20, a motor terminal 27, capacitors 35, 36 and 37, and a sensor housing 30.
コンデンサ35,36,37は、ICパッケージ10に設けられる。
コンデンサ35は、第一溶接端子211と迂回部222とをx軸に沿う方向で接続するよう設けられる。
コンデンサ36は、電源溶接端子231と迂回部222とをx軸に沿う方向で接続するよう設けられる。
コンデンサ37は、第二溶接端子241と迂回部222とをx軸に沿う方向で接続するよう設けられる。 The capacitors 35, 36 and 37 are provided in the IC package 10.
Capacitor 35 is provided to connect first welding terminal 211 and bypass portion 222 in a direction along the x-axis.
Capacitor 36 is provided to connect power supply welding terminal 231 and bypass portion 222 in a direction along the x-axis.
Thecapacitor 37 is provided so as to connect the second welding terminal 241 and the bypass portion 222 in a direction along the x axis.
コンデンサ35は、第一溶接端子211と迂回部222とをx軸に沿う方向で接続するよう設けられる。
コンデンサ36は、電源溶接端子231と迂回部222とをx軸に沿う方向で接続するよう設けられる。
コンデンサ37は、第二溶接端子241と迂回部222とをx軸に沿う方向で接続するよう設けられる。 The
The
ICパッケージ10では、体格を小さくするためには、第一磁気検出素子11、第一信号処理回路110、第二磁気検出素子12及び第二信号処理回路120とともに封止部13によって封止される図示しないコンデンサの大きさに制約があり、一定程度の耐EMC性を確保することが難しい。
そこで、第二実施形態による回転角検出装置では、第一溶接端子211と迂回部222との間、電源溶接端子231と迂回部222との間、及び、第二溶接端子241と迂回部222との間に外付けのコンデンサ35,36,37を設けることによってノイズを低減することができる。これにより、第二実施形態は、第一実施形態と同じ効果を奏するとともに、耐EMC性を向上することができる。 In theIC package 10, in order to reduce the physique, the first magnetic detection element 11, the first signal processing circuit 110, the second magnetic detection element 12, and the second signal processing circuit 120 are sealed by the sealing unit 13. The size of the capacitor (not shown) is limited, and it is difficult to ensure a certain degree of EMC resistance.
Therefore, in the rotation angle detection device according to the second embodiment, between thefirst welding terminal 211 and the bypass portion 222, between the power welding terminal 231 and the bypass portion 222, and between the second weld terminal 241 and the bypass portion 222, Noise can be reduced by providing external capacitors 35, 36, and 37 between the two. Thereby, 2nd embodiment can improve EMC resistance while having the same effect as 1st embodiment.
そこで、第二実施形態による回転角検出装置では、第一溶接端子211と迂回部222との間、電源溶接端子231と迂回部222との間、及び、第二溶接端子241と迂回部222との間に外付けのコンデンサ35,36,37を設けることによってノイズを低減することができる。これにより、第二実施形態は、第一実施形態と同じ効果を奏するとともに、耐EMC性を向上することができる。 In the
Therefore, in the rotation angle detection device according to the second embodiment, between the
また、第二実施形態による回転角検出装置の製造工程において、ダイバーが切断された領域にコンデンサ35,36,37を設けることができる。これにより、ICパッケージ10とセンサターミナル20との間にコンデンサ35,36,37を容易に設けることができる。
Further, in the manufacturing process of the rotation angle detection device according to the second embodiment, the capacitors 35, 36, and 37 can be provided in the region where the diver is cut. Thereby, the capacitors 35, 36, and 37 can be easily provided between the IC package 10 and the sensor terminal 20.
また、第二実施形態による回転角検出装置では、コンデンサ35,36,37は、センサハウジング30の短手方向であるx軸に沿う方向で接続するよう設けられる。これにより、センサハウジング30が熱によって膨張するとき、短手方向は熱膨張の度合いが比較的小さいため、コンデンサ35,36,37が破損することを防止することができる。
Further, in the rotation angle detection device according to the second embodiment, the capacitors 35, 36, and 37 are provided so as to be connected in a direction along the x axis that is the short direction of the sensor housing 30. As a result, when the sensor housing 30 is expanded by heat, the degree of thermal expansion is relatively small in the short direction, so that the capacitors 35, 36, and 37 can be prevented from being damaged.
(第三実施形態)
