第１のハウジング４０は、大小２つの円弧部を連結した外形が略小判状の本体部４１と、本体部４１の小さな円弧部の中心部に同心上に形成された固定部４２と、本体部４１の大きな円弧部の中心部から前方（＋Ｚ方向）に突き出して一体に形成された収容部４３と、本体部４１の大きな円弧部から後方（−Ｚ方向）に突き出して一体に形成されたコネクタ部４４と、を備えて構成されており、例えばポリブチレンテレフタレート（ＰＢＴ：Poly Butylene Terephthalate）樹脂など合成樹脂製とされている。なお、２つの円弧部の大きさは同じであっても良い。 The first housing 40 has a main body 41 having a substantially oval shape in which two large and small arcs are connected, a fixing portion 42 formed concentrically at the center of the small arc of the main 41, and a main body. A housing portion 43 that protrudes forward (+ Z direction) from the center of the large arc portion of 41 and is integrally formed, and a connector that protrudes rearward (-Z direction) from the large arc portion of the main body 41 and is integrally formed. It is configured to include a portion 44, and is made of a synthetic resin such as a poly butylene terephthalate (PBT) resin. The sizes of the two arc portions may be the same.

固定部４２は、金属製で円筒状のカラー４２ａを備えるとともに、第１のハウジング４０の本体部４１の上方（＋Ｙ方向）に突き出す部分に一体化されている。固定部４２は、本体部４１の小さな円弧部に金属製の円筒状のカラー４２ａをインサート成形することで一体化されている。カラー４２ａには、図３に示すように、後方（−Ｚ方向）から固定対象７０に設けられたネジ孔７２に固定用ボルトを入れて締め付けることで、第１のハウジング４０を固定できる。
本体部４１は、大きな円弧部の内側縁部と小さな円弧部のカラー４２ａの大きな円弧部側の半円部とで囲まれる部分が側壁部４１ａとされ、側壁部４１ａで囲まれた内側部分が凹部とされて平板状の底板部４１ｂで後方（−Ｚ方向）側が塞がれている。 The fixing portion 42 is provided with a metal cylindrical collar 42a, and is integrated with a portion protruding upward (+ Y direction) of the main body portion 41 of the first housing 40. The fixing portion 42 is integrated by insert molding a metal cylindrical collar 42a into a small arc portion of the main body portion 41. As shown in FIG. 3, the collar 42a can be fixed to the first housing 40 by inserting a fixing bolt into a screw hole 72 provided in the fixing target 70 from the rear (−Z direction) and tightening the collar 42a.
In the main body 41, the portion surrounded by the inner edge of the large arc and the semicircle on the side of the large arc of the collar 42a of the small arc is the side wall 41a, and the inner portion surrounded by the side wall 41a is.

The wall surface portion 43a2 is provided with a positioning portion (second positioning portion) 43a4 corresponding to the positioning portion 11d of the magnet 11. The upper ends of the wall surface portion 43a2, the side wall portion 43a3, and the substrate mounting portion 43b are aligned. By mounting the circuit board 20 on the board mounting portion 43b, the circuit board 20 partially blocks the upper part (+ Y direction) of the housing portion 43a. The magnet 11 is housed in the storage unit 43a in a state of being coupled to the magnetic detection element 10, and is coupled to the storage unit 43a by a method such as adhesion. At this time, the surface 10a of the magnetic detector 10 is exposed in front of the substrate mounting portion 43b (in the + Z direction) (see FIG. 4). The side walls 43a3 may be provided on both sides of the bottom surface portion 43a1, but if they are provided on only one side as shown in the figure, it is desirable because it is easy to check the fitting state of the magnet 11 and the storage portion 43a.

基板載置部４３ｂには、３つの基板接続部３１ｂが突出している。基板接続部３１ｂはそれぞれ回路基板２０のランド２１に通された後、半田付けなどの方法により回路基板２０と電気的に接続される。 Three board connecting portions 31b project from the board mounting portion 43b. Each of the board connection portions 31b is passed through the land 21 of the circuit board 20, and then electrically connected to the circuit board 20 by a method such as soldering.

円柱部４３ｃの外周部には、Ｏリング溝が形成されてＯリング４５が装着され、後述する嵌合連結される第２のハウジング５０との間をシール状態とする。 An O-ring groove is formed on the outer peripheral portion of the cylindrical portion 43c, and the O-ring 45 is mounted on the outer peripheral portion, and a seal state is provided between the O-ring 45 and the second housing 50 to be fitted and connected, which will be described later.

コネクタ部４４は、中空の四角筒状とされて後方（−Ｚ方向）が開口し、本体部４１の底板部４１ｂの裏面４１ｃから後方に突き出して一体に形成されており、外部の装着側のコネクタ（図示せず）を所定の向きに連結でき、係止凹凸部によってコネクタ同士の係止連結状態を保持できるようにしてある。 The connector portion 44 has a hollow square tubular shape and opens rearward (in the −Z direction), and protrudes rearward from the back surface 41c of the bottom plate portion 41b of the main body portion 41 to be integrally formed. The connectors (not shown) can be connected in a predetermined direction, and the locking connection state between the connectors can be maintained by the locking uneven portion.

第２のハウジング５０は、図１，図９に示すように第１のハウジング４０の一方側（前方側（＋Ｚ方向））の収容部４３（図３参照）を覆って嵌合連結され被検出体Ｄ（図２参照）と対向して配置される有底の円筒部５１と、円筒部５１の開口端に一体に形成されたフランジ部５２とを備えて形成されている。第２のハウジング５０は、第１のハウジング４０と同一の合成樹脂製、例えば、ポリブチレンテレフタレート（ＰＢＴ）樹脂など合成樹脂製とされている。
第２のハウジング５０は、第１のハウジング４０に一体に形成された収容部４３に収容された磁気検出素子１０および磁石１１などを覆うカバーとして円筒部５１が機能しており、円筒部５１の外周には、補強用のリブ５１ａが円周方向等間隔に複数本一体に形成してある。リブ５１ａにより、剛性を高めて固定対象７０からの振動の影響を緩和する。また、リブ５１ａは、Ｏリング５３取り付け時の誘い込みおよび移動体検出装置１００を固定対象７０に取り付ける際の誘い込みとしての機能を有している。円筒部５１のリブ５１ａの後方には、Ｏリング溝５１ｂが形成され、Ｏリング５３が装着され、固定対象７０との間をシールするとともに、Ｏリング５３によって固定対象７０からの振動の第１のハウジング４０への伝達を抑えている。
フランジ部５２は、第１のハウジング４０の側壁部４１ａの内側形状に沿った外形状に形成されており、周囲を囲む側壁部５２ａと、側壁部５２ａの前方側の開口部を塞ぐとともに、円筒部５１が一体に設けられた蓋板部５２ｂとで構成される。側壁部５２ａの底面５２ｃは、第１のハウジング４０とのＺ方向の接触面である。
これにより、第２のハウジング５０を第１のハウジング４０の内側に被せるように装着して連結することで、第１のハウジング４０の側壁部４１ａの内側に、第２のハウジング５０のフランジ部５２の側壁部５２ａが接するように嵌合され、側壁部４１ａの開口部が蓋板部５２ｂで塞がれた状態となり、フランジ部５２が第１のハウジング４０の固定部４２と同一の厚みとなる。
すなわち、第１のハウジング４０の本体部４１の側壁部４１ａの高さと第２のハウジング５０のフランジ部５２の側壁部５２ａの高さが、嵌合連結状態とした場合に、蓋板部５２ｂが第１のハウジング４０の固定部４２と同一の厚みとなるように設定してある。
また、第２のハウジング５０のフランジ部５２は、第１のハウジング４０を固定部４２によって固定対象７０（図３参照）に固定設置すると、第１のハウジング４０と固定対象７０とに挟み込まれることになり、移動体検出装置１００を確実に固定対象７０に保持することができる。 As shown in FIGS. 1 and 9, the second housing 50 is fitted and connected so as to cover one side (front side (+ Z direction)) of the accommodating portion 43 (see FIG. 3) of the first housing 40 to be detected. A bottomed cylindrical portion 51 arranged to face the body D (see FIG. 2) and a flange portion 52 integrally formed at the open end of the cylindrical portion 51 are provided. The second housing 50 is made of the same synthetic resin as the first housing 40, for example, a synthetic resin such as polybutylene terephthalate (PBT) resin.
In the second housing 50, the cylindrical portion 51 functions as a cover for covering the magnetic detection element 10 and the magnet 11 housed in the accommodating portion 43 integrally formed with the first housing 40, and the cylindrical portion 51 of the cylindrical portion 51. A plurality of reinforcing ribs 51a are integrally formed on the outer periphery at equal intervals in the circumferential direction. The rib 51a increases the rigidity and alleviates the influence of vibration from the fixing target 70. Further, the rib 51a has a function of attracting when the O-ring 53 is attached and as an invitation when the moving body detecting device 100 is attached to the fixing target 70. An O-ring groove 51b is formed behind the rib 51a of the cylindrical portion 51, an O-ring 53 is mounted, and the O-ring 53 seals between the rib 51a and the fixing target 70, and the first vibration from the fixing target 70 is performed by the O-ring 53. Is suppressed from being transmitted to the housing 40.
The flange portion 52 is formed in an outer shape along the inner shape of the side wall portion 41a of the first housing 40, closes the side wall portion 52a surrounding the periphery and the opening on the front side of the side wall portion 52a, and is cylindrical. It is composed of a lid plate portion 52b integrally provided with the portion 51. The bottom surface 52c of the side wall portion 52a is a contact surface in the Z direction with the first housing 40.
As a result, by mounting and connecting the second housing 50 so as to cover the inside of the first housing 40, the flange portion 52 of the second housing 50 is inside the side wall portion 41a of the first housing 40. The side wall portion 52a is fitted so as to be in contact with each other, the opening of the side wall portion 41a is closed by the lid plate portion 52b, and the flange portion 52 has the same thickness as the fixing portion 42 of the first housing 40. ..
That is, when the height of the side wall portion 41a of the main body portion 41 of the first housing 40 and the height of the side wall portion 52a of the flange portion 52 of the second housing 50 are in the fitted and connected state, the lid plate portion 52b It is set to have the same thickness as the fixing portion 42 of the first housing 40.
Further, the flange portion 52 of the second housing 50 is sandwiched between the first housing 40 and the fixing target 70 when the first housing 40 is fixedly installed on the fixing target 70 (see FIG. 3) by the fixing portion 42. Therefore, the moving body detection device 100 can be reliably held by the fixing target 70.

第１のハウジング４０と第２のハウジング５０との間には、図４，図９に示すように嵌合連結状態を保持する連結保持機構６０が設けられている。
固定対象７０に固定される固定側となる第１のハウジング４０には、側壁部４１ａに４箇所の係合凹部６１が略矩形の孔として形成されている。
第１のハウジング４０に嵌合連結される連結側となる第２のハウジング５０の側壁部５２ａに、係合凹部６１に内側から外側に向かって係合するフックを備えた係合凸部６２が一体に形成されている。
これにより、第２のハウジング５０の側壁部５２ａを第１のハウジング４０の側壁部４１ａの内側に装着して連結することで、第２のハウジング５０の係合凸部６２のフックが第１のハウジング４０の係合凹部６１の孔に係合し、第１のハウジング４０と第２のハウジング５０の嵌合連結状態が連結保持機構６０で保持される。
なお、係合凹部６１と係合凸部６２は、逆に第１のハウジング４０に係合凸部６２を設け、第２のハウジング５０に係合凹部６１を設けるようにしても良い。
さらに、この移動体検出装置１００では、第１のハウジング４０を、固定部４２を介して固定対象７０に固定設置すると、第１のハウジング４０に嵌合連結した第２のハウジング５０のフランジ部５２が、第１のハウジング４０と固定対象７０とに挟み込まれることになり、例え、連結保持機構６０による嵌合連結状態に問題が生じても移動体検出装置１００を確実に固定対象７０に保持することができる（図３を合わせて参照）。 As shown in FIGS. 4 and 9, a connection holding mechanism 60 for holding a fitted and connected state is provided between the first housing 40 and the second housing 50.
In the first housing 40 on the fixing side fixed to the fixing target 70, four engaging recesses 61 are formed in the side wall portion 41a as substantially rectangular holes.
An engaging convex portion 62 having a hook that engages with the engaging concave portion 61 from the inside to the outside is provided on the side wall portion 52a of the second housing 50 on the connecting side that is fitted and connected to the first housing 40. It is formed integrally.
As a result, the side wall portion 52a of the second housing 50 is mounted inside the side wall portion 41a of the first housing 40 and connected, so that the hook of the engaging convex portion 62 of the second housing 50 becomes the first. It engages with the hole of the engaging recess 61 of the housing 40, and the fitting and connecting state of the first housing 40 and the second housing 50 is held by the connecting holding mechanism 60.
On the contrary, the engaging concave portion 61 and the engaging convex portion 62 may be provided with the engaging convex portion 62 in the first housing 40 and the engaging concave portion 61 in the second housing 50.
Further, in the moving body detecting device 100, when the first housing 40 is fixedly installed on the fixing target 70 via the fixing portion 42, the flange portion 52 of the second housing 50 fitted and connected to the first housing 40. However, it is sandwiched between the first housing 40 and the fixing target 70, and even if there is a problem in the fitting and connecting state by the connection holding mechanism 60, the moving body detection device 100 is reliably held by the fixing target 70. Can be done (see also Figure 3).

移動体検出装置１００は、図３に示すように、円柱部４３ｃにＯリング４５を装着し、収容部４３に磁気検出素子１０および磁石１１を収納した第１のハウジング４０に第２のハウジング５０を被せるようにして嵌合連結し、連結保持機構６０の係合凹部６１と係合凸部６２とを係合して連結状態を保持する。また、第２のハウジング５０のＯリング溝５１ｂにＯリング５３を装着しておく。
次いで、移動体検出装置１００を、固定対象７０に形成した被検出体Ｄと対向する取付孔７１に第２のハウジング５０を装着するようにし、第１のハウジング４０の固定部４２のカラー４２ａに入れた取付ボルトを固定対象７０に締め付けることで固定する。コネクタ部４４には、外部から装着用のコネクタが接続され、検出信号を外部に出力できるようにする。
これにより、移動体検出装置１００は、固定用ボルトで固定対象７０に固定され、被検出体Ｄと磁気検出素子１０が対向した状態となり、被検出体の移動量（回転数など）が磁気検出素子１０で検出（計測）される。 As shown in FIG. 3, the moving body detection device 100 has an O-ring 45 mounted on a cylindrical portion 43c, and a second housing 50 in a first housing 40 in which a magnetic detection element 10 and a magnet 11 are housed in a housing portion 43. The engaging concave portion 61 of the connecting holding mechanism 60 and the engaging convex portion 62 are engaged with each other to maintain the connected state. Further, the O-ring 53 is mounted in the O-ring groove 51b of the second housing 50.
Next, the moving body detecting device 100 is mounted on the mounting hole 71 facing the detected body D formed in the fixing target 70 so that the second housing 50 is mounted on the collar 42a of the fixing portion 42 of the first housing 40. It is fixed by tightening the inserted mounting bolt to the fixing target 70. A mounting connector is connected to the connector unit 44 from the outside so that the detection signal can be output to the outside.
As a result, the moving body detection device 100 is fixed to the fixing target 70 with the fixing bolts, the detected body D and the magnetic detection element 10 are in a state of facing each other, and the movement amount (rotation speed, etc.) of the detected body is magnetically detected. It is detected (measured) by the element 10.

移動体検出装置１００では、第１のハウジング４０に収容部４３を一体に形成してリード端子３０をインサート成形により埋設一体化しておき、収容部４３に磁気検出素子１０と磁石１１を収容し、第１のハウジング４０を、固定部４２を介して固定対象７０に固定しているので、被検出体Ｄの振動系と移動体検出装置１００の振動系が同一となる。
これにより、従来の装置では、第２のハウジング５０を機器側である固定対象７０に固定し、第２のハウジング５０に第１のハウジング４０を連結していたので、被検出体の振動が第２のハウジング５０を介して磁気検出素子１０や磁石１１が収容固定された第１のハウジング４０に伝達され、２つの振動系から振動が伝達され、これらの振動の影響により検出精度の低下を招いていたが、本発明の移動体検出装置１００によれば、振動系が１つとなり振動の影響を抑えて高精度に検出することができる。
移動体検出装置１００では、第１のハウジング４０の内側に第２のハウジング５０を配置して嵌合連結するようにしたので、第２のハウジング５０をコンパクトにすることができ、小型軽量化により振動系の質量を小さくして振動の影響を抑えることができる。 In the mobile body detection device 100, the accommodating portion 43 is integrally formed in the first housing 40, the lead terminal 30 is embedded and integrated by insert molding, and the magnetic detection element 10 and the magnet 11 are accommodated in the accommodating portion 43. Since the first housing 40 is fixed to the fixing target 70 via the fixing portion 42, the vibration system of the detected body D and the vibration system of the moving body detection device 100 are the same.
As a result, in the conventional device, the second housing 50 is fixed to the fixing target 70 on the device side, and the first housing 40 is connected to the second housing 50, so that the vibration of the detected body is the second. The magnetic detection element 10 and the magnet 11 are transmitted to the first housing 40 in which the magnetic detection element 10 and the magnet 11 are housed and fixed via the housing 50 of 2, and vibrations are transmitted from the two vibration systems, and the influence of these vibrations causes a decrease in detection accuracy. However, according to the moving body detector 100 of the present invention, the vibration system becomes one, and the influence of vibration can be suppressed and the detection can be performed with high accuracy.
In the moving body detection device 100, since the second housing 50 is arranged inside the first housing 40 so as to be fitted and connected, the second housing 50 can be made compact, and the size and weight can be reduced. The mass of the vibration system can be reduced to suppress the influence of vibration.

本発明の移動体検出装置１００は、被検出体Ｄの移動に応じた電気信号を出力する磁気検出素子１０と、磁気検出素子１０に磁界を加える磁石１１と、磁気検出素子１０、磁石１１を収容する収納部４３ａを有する第１のハウジング４０と、収納部４３ａを覆って第１のハウジング４０と嵌合連結され被検出体Ｄと対向して配置される第２のハウジング５０と、を備え、磁石１１の磁気検出素子１０側の面の裏面１１ｂ側に設けた第１位置決め部１１ｄと、収納部４３ａに設けた第２位置決め部４３ａ４と、が嵌合してなるものである。このような構造にすることによって、第１のハウジング４０に対する磁石１１の取り付け角度が規定されるため、被検出体Ｄの検出精度が向上することが期待できる。 The moving body detection device 100 of the present invention includes a magnetic detection element 10 that outputs an electric signal corresponding to the movement of the object D to be detected, a magnet 11 that applies a magnetic field to the magnetic detection element 10, a magnetic detection element 10, and a magnet 11. A first housing 40 having a storage portion 43a to be housed, and a second housing 50 that covers the storage portion 43a, is fitted and connected to the first housing 40, and is arranged so as to face the detector D. The first positioning portion 11d provided on the back surface 11b side of the surface of the magnet 11 on the magnetic detection element 10 side and the second positioning portion 43a4 provided on the storage portion 43a are fitted to each other. With such a structure, the mounting angle of the magnet 11 with respect to the first housing 40 is defined, so that it can be expected that the detection accuracy of the object to be detected D will be improved.

磁気検出素子１０の検出面１０ａの裏面１０ｂ側に第３位置決め部１０ｅと、
磁石１１の表面１１ａ側に第４位置決め部１１ｃと、を備え、第３位置決め部１０ｅと、第４位置決め部１１ｃと、が嵌合してなることが望ましい。このような構造にすることによって、磁石に対する磁気検出素子の取り付け角度が規制されるため、被検出体Ｄの検出精度が向上することが期待できる。 On the back surface 10b side of the detection surface 10a of the magnetic detection element 10, a third positioning portion 10e and
It is desirable that the fourth positioning portion 11c is provided on the surface 11a side of the magnet 11, and the third positioning portion 10e and the fourth positioning portion 11c are fitted to each other. With such a structure, the mounting angle of the magnetic detector element with respect to the magnet is restricted, so that it can be expected that the detection accuracy of the detected body D will be improved.

収納部４３ａは、壁面部４３ａ２を備え、更に、底面部４３ａ１と、左右の面である側壁４３ａと、の３面のうち、いずれか２つのみを備えてなる（すなわち、上方（＋Ｙ方向）、前方（＋Ｚ方向）以外にも開口面を備えている）ことが望ましい。このような構造にすることによって、第１のハウジング４０と磁石１１、磁石１１と磁気検出素子１０の嵌合状態の確認が容易となり、嵌合不良品（検出精度が悪いもの）が流出することを予防できる。 The storage portion 43a includes a wall surface portion 43a2, and further includes only one of three surfaces, a bottom surface portion 43a1 and side walls 43a, which are left and right surfaces (that is, upward (in the + Y direction)). , It is desirable to have an opening surface other than the front (+ Z direction). With such a structure, it becomes easy to confirm the fitting state of the first housing 40 and the magnet 11, and the magnet 11 and the magnetic detection element 10, and defective fitting products (those with poor detection accuracy) flow out. Can be prevented.
