Description

本発明は、摺動子を取り付けた移動体を円弧状に移動させることで検出出力を変化させる電子部品に関するものである。 The present invention relates to an electronic component that changes a detection output by moving a moving body to which a slider is attached in an arc shape.

従来、例えば一眼レフカメラの絞り、ズーム、ピント等の調整のための操作手段として、スライド式の電子部品が利用されている。この種の電子部品は、例えば特許文献１の図１６に示すように、フレキシブル回路基板（４０）を、金型（１０），（３０）の円弧状に湾曲するキャビティー（Ｃ）内に収納し、キャビティー（Ｃ）内のフレキシブル回路基板（４０）の下面側から溶融成形樹脂を充填することで、図１２に示すような基台付き基板（１−２）を作成し、この基台付き基板（１−２）の前記フレキシブル回路基板（４０）を露出した側に、摺動子（１５０）を取り付けた移動体（１３０）を取り付けて構成される。 Conventionally, slide-type electronic components have been used as operation means for adjusting, for example, the aperture, zoom, and focus of a single-lens reflex camera. In this type of electronic component, for example, as shown in FIG. 16 of Patent Document 1, the flexible circuit board (40) is accommodated in a cavity (C) that is curved in an arc shape of the molds (10) and (30). Then, by filling the molding resin from the lower surface side of the flexible circuit board (40) in the cavity (C), a base board (1-2) as shown in FIG. A movable body (130) with a slider (150) attached is attached to the side of the attached board (1-2) where the flexible circuit board (40) is exposed.

そしてこの電子部品（１００）の移動体（１３０）は、そのレール係合部（１３１）を基台（６０）のレール部（６１）に係合することで、円弧状にスライド移動可能となっており、これによってフレキシブル回路基板（４０）に形成した摺接パターン（４３），（４５）上を摺動子（１５０）が摺動してその検出出力を変化させる。この種のスライド式の電子部品（１００）は、例えば、一眼レフカメラの望遠ズームレンズの外筒に取り付けられ、前述のように、絞り、ズーム、ピント等の調整のために使用される。 The moving body (130) of the electronic component (100) can be slid in an arc shape by engaging the rail engaging portion (131) with the rail portion (61) of the base (60). As a result, the slider (150) slides on the sliding contact patterns (43) and (45) formed on the flexible circuit board (40) to change the detection output. This type of slide-type electronic component (100) is attached to, for example, an outer cylinder of a telephoto zoom lens of a single-lens reflex camera, and is used for adjusting a diaphragm, zoom, focus, and the like as described above.

しかしながら、上記従来の電子部品（１００）に用いる基台付き基板（１−２）においては、その製造方法が図１６に示すように、キャビティー（Ｃ）を形成する円弧の外周面側と内周面側に金型（１０），（３０）を配置してその中にフレキシブル回路基板（４０）を設置し、その際フレキシブル回路基板（４０）の両端を金型（１０），（３０）のキャビティーＣの両外側部分で挟持する構造なので、円弧の範囲が１８０°以下に限られてしまい、１８０°以上の円弧を有する基台付き基板を製造することは困難であった。従って、上記基台付き基板（１−２）においては、移動体（１３０）（即ち摺動子（１５０））の移動範囲が１８０°以内に限られてしまう。これらのことから、１８０°以上の移動範囲で移動体（摺動子）を移動できる、構造の簡単な電子部品が望まれていた。 However, in the substrate with a base (1-2) used for the conventional electronic component (100), the manufacturing method is as shown in FIG. 16, and the outer peripheral side and the inner side of the arc forming the cavity (C) are used. The molds (10) and (30) are arranged on the peripheral surface side, and the flexible circuit board (40) is installed therein. At that time, both ends of the flexible circuit board (40) are placed in the molds (10) and (30). Therefore, it is difficult to manufacture a substrate with a base having an arc of 180 ° or more. Therefore, in the substrate with base (1-2), the moving range of the moving body (130) (that is, the slider (150)) is limited to 180 ° or less. For these reasons, there has been a demand for an electronic component with a simple structure that can move a moving body (slider) within a moving range of 180 ° or more.

本発明は上述の点に鑑みてなされたものでありその目的は、移動体の移動範囲（摺動子の摺動範囲）を容易に１８０°以上にすることができる、構造が簡単で組み立ての容易な電子部品を提供することにある。 The present invention has been made in view of the above points, and its purpose is to make the moving range of the moving body (sliding range of the slider) easily 180 ° or more. The object is to provide an easy electronic component.

本発明にかかる電子部品は、外周面が円弧状の基板取付面となっている基台と、前記基台の基板取付面に取り付けられるフレキシブル回路基板と、前記フレキシブル回路基板の外周面に沿うように移動する移動体と、前記移動体に取り付けられて前記フレキシブル回路基板の外周面に設けた摺接パターンに摺接する摺動子と、を具備し、前記基台の円周方向に沿う一方の端辺側に、前記移動体の一方の端辺側に設けた係止部をスライド自在に係止する第１レール部を設け、さらに前記基台の円周方向に沿う他方の端辺側に、前記移動体の他方の端辺側に設けた係止部をスライド自在に係止する第２レール部を形成してなるカバーを取り付けたことを特徴としている。
本発明によれば、移動体の両端辺側にそれぞれ設けた係止部を係止するために必要な一対の第１，第２レール部の内、一方の第１レール部のみを、基台の一方の端辺側に設け、他方の第２レール部は別部材であるカバーに設けたので、１８０°以上の円弧からなる基板取付面を有する基台を容易に製造することが可能になる（仮に、基板取付面から半径方向外方に突出する部分に形成する第１，第２レール部を、基台の両端辺側に一体成型で設け、且つ基台を円弧状に成形する場合は、円弧が１８０°を超えると、その成形が金型上困難になる）。これによって移動体の移動範囲（摺動子の摺動範囲）を容易に１８０°以上とすることができる。またこの電子部品はその構造が簡単で、容易に組み立てができる。 An electronic component according to the present invention has a base whose outer peripheral surface is an arc-shaped substrate mounting surface, a flexible circuit board attached to the substrate mounting surface of the base, and an outer peripheral surface of the flexible circuit board.

According to the present invention, only one first rail portion of the pair of first and second rail portions necessary for locking the locking portions provided on both sides of the movable body is mounted on the base. Since the other second rail portion is provided on a cover which is a separate member, it is possible to easily manufacture a base having a substrate mounting surface made of an arc of 180 ° or more. (Temporarily, the first and second rail portions formed on the portion protruding radially outward from the board mounting surface are integrally formed on both sides of the base, and the base is formed into an arc shape. When the arc exceeds 180 °, the molding becomes difficult on the mold). Thereby, the moving range of the moving body (sliding range of the slider) can be easily set to 180 ° or more. This electronic component has a simple structure and can be easily assembled.

これによって、移動体（摺動子）を略３６０°（更には３６０°以上）回転することができる。また基台の外周面に対して中心から外方に向かって突出する第１，第２レール形成部を基台とカバーの両者に１つずつ形成したので、略円筒状に形成される基台とカバーの両者の製造が何れも容易に行える。また第１，第２レール形成部を基台の外周面に対して中心から外方に向かって突出して設け、これら第１，第２レール形成部に第１，第２レール部を形成したので、移動体全体をフレキシブル回路基板の外周側露出面よりも半径方向外側に位置させることができ、略３６０°にわたって回転する移動体にフレキシブル回路基板（特にフレキシブル回路基板の外部への引出部の部分）が干渉することを容易に避けることができる。 Further, according to the present invention, the base is formed in a substantially cylindrical shape, and the outer peripheral surface thereof is the substrate mounting surface, and one end side of the base is centered with respect to the outer peripheral surface of the base. A first rail forming portion that protrudes outward is provided. On the other hand, when the cover is attached to the other end of the base, the first rail forming portion is outside the center with respect to the outer peripheral surface of the base. A second rail forming portion that protrudes in the direction is provided, and the first and second rail portions are formed in the first and second rail forming portions, respectively.
As a result, the moving body (slider) can be rotated approximately 360 ° (further 360 ° or more). Also, since the first and second rail forming portions that protrude outward from the center with respect to the outer peripheral surface of the base are formed on each of the base and the cover, the base is formed in a substantially cylindrical shape. Both the cover and the cover can be easily manufactured. Also, the first and second rail forming portions are provided so as to protrude outward from the center with respect to the outer peripheral surface of the base, and the first and second rail forming portions are formed on these first and second rail forming portions. The entire movable body can be positioned radially outward from the outer peripheral side exposed surface of the flexible circuit board, and the movable body rotates about 360 ° to the flexible circuit board (particularly the portion of the lead-out portion to the outside of the flexible circuit board). ) Can easily be avoided.

また本発明は、前記フレキシブル回路基板の一方の端辺に設けた係止部を、前記第１レール形成部に設けた被係止部に係止することによって、このフレキシブル回路基板を前記基台の基板取付面に取り付けることを特徴としている。

It comprises. The entire surface of the movable body 111 is curved in an arc along the moving direction (sliding direction) H of the movable body 110. The radius of curvature of the arc is substantially the same as the radius of curvature of the board mounting surface 11 of the base 10. A planar slider mounting surface 115 is formed on the lower surface of the movable body main body 111, and a pair of small protrusion-shaped slider mounting portions 117 are provided on the slider mounting surface 115. . In addition, the front and rear positions (positions near the four corners) in the movement direction H around the outer periphery of the movable body main body 111 are a pair of left and right pairs that are substantially rectangular and projecting in a direction perpendicular to the movement direction H. A shaped locking portion 119 is provided. Each locking portion 119 is formed in a shape and dimension that is inserted into the first rail portion 17 provided on the base 10 and the second rail portion 85 provided on the cover 80.

摺動子１３０は、弾性金属板製であり、平板状の摺動子基部１３１の外周の１辺から突出する一対の摺動冊子１３３をその根元部分で約１８０°折り曲げて構成されている。摺動子基部１３１には、前記移動体１１０の各摺動子取付部１１７を挿入する小孔からなる被取付部１３５が設けられている。 The slider 130 is made of an elastic metal plate, and is configured by bending a pair of sliding booklets 133 protruding from one side of the outer periphery of a flat-plate-like slider base portion 131 at the base portion thereof by about 180 °. The slider base 131 is provided with a mounted portion 135 having a small hole into which each slider mounting portion 117 of the moving body 110 is inserted.

次に電子部品１−１の組立方法を説明する。まず予め、移動体１１０の摺動子取付面１１５に摺動子１３０の摺動子基部１３１を当接し、その際、移動体１１０の各摺動子取付部１１７を摺動子１３０の各被取付部１３５に挿入し、熱カシメ等によって固定しておく。そして、基台１０の基板取付面１１上に、摺接パターン５５，５７を外向きとしてリング状に湾曲させたフレキシブル回路基板５０を設置する。その際、フレキシブル回路基板５０に設けた各係止部６３を基台１０に設けた各被係止部１９に挿入・係止し、これによってフレキシブル回路基板５０を基台１０の基板取付面１１に取り付ける。このようにフレキシブル回路基板５０の係止部６３を、基台１０の被係止部１９に係止することによって、簡単にこのフレキシブル回路基板５０を基台１０の基板取付面１１に取り付けることができる。 Next, a method for assembling the electronic component 1-1 will be described. First, the slider base portion 131 of the slider 130 is brought into contact with the slider mounting surface 115 of the moving body 110 in advance, and at this time, each slider mounting portion 117 of the moving body 110 is connected to each cover of the slider 130. It is inserted into the attachment part 135 and fixed by heat caulking or the like. Then, the flexible circuit board 50 that is curved in a ring shape with the sliding contact patterns 55 and 57 facing outward is installed on the board mounting surface 11 of the base 10. At that time, each locking portion 63 provided on the flexible circuit board 50 is inserted and locked into each locked portion 19 provided on the base 10, whereby the flexible circuit board 50 is attached to the board mounting surface 11 of the base 10. Attach to. Thus, by locking the locking portion 63 of the flexible circuit board 50 to the locked portion 19 of the base 10, the flexible circuit board 50 can be easily attached to the board mounting surface 11 of the base 10. it can.

次に、前記摺動子１３０を取り付けた移動体１１０をフレキシブル回路基板５０の外周面上に配置し、その際、摺動子１３０の各摺動冊子１３３を各摺接パターン５５，５７に当接する（図５参照）。このとき同時に、移動体１１０の下側の２つの係止部１１９を基台１０の第１レール部１７に挿入する（図５参照）。 Next, the movable body 110 to which the slider 130 is attached is disposed on the outer peripheral surface of the flexible circuit board 50, and at that time, the sliding booklets 133 of the slider 130 are respectively brought into contact with the sliding contact patterns 55 and 57. (Refer to FIG. 5). At the same time, the two locking portions 119 on the lower side of the moving body 110 are inserted into the first rail portion 17 of the base 10 (see FIG. 5).

次に、前記基台１０の上側の端辺２１上に、カバー８０を載置し、その際、カバー８０の各被取付部８９に基台１０の各取付部２３を挿入し、カバー８０の上面から突出する各取付部２３を熱カシメして固定する。このとき図６に示すように、フレキシブル回路基板５０の上部の部分は、基台１０の基板取付面１１とカバー８０の係止用突起８３の間に挟持され、固定される。つまり、フレキシブル回路基板５０は、その上下の端辺６１，６４近傍部分が固定されることで、基板取付面１１への取り付けが確実になる。また同時に、移動体１１０の上側の２つの係止部１１９がカバー８０の第２レール部８５に挿入される（図５参照）。さらにこのとき、フレキシブル回路基板５０の引出部６５は、カバー８０に設けた引出部挿通部９１内を通って、カバー８０の上方に引き出される（図５参照）。以上によって、電子部品１−１の組み立てが完了する。なお上記組立手順はその一例であり、他の各種異なる組立手順を用いて組み立てても良いことはいうまでもない。 Next, the cover 80 is placed on the upper edge 21 of the base 10, and at this time, each mounting portion 23 of the base 10 is inserted into each mounted portion 89 of the cover 80, Each mounting portion 23 protruding from the upper surface is fixed by caulking. At this time, as shown in FIG. 6, the upper portion of the flexible circuit board 50 is sandwiched and fixed between the board mounting surface 11 of the base 10 and the locking projection 83 of the cover 80. That is, the flexible circuit board 50 is securely attached to the board attachment surface 11 by fixing the vicinity of the upper and lower edges 61 and 64 thereof. At the same time, the two upper locking portions 119 of the moving body 110 are inserted into the second rail portion 85 of the cover 80 (see FIG. 5). Further, at this time, the lead-out portion 65 of the flexible circuit board 50 passes through the lead-out portion insertion portion 91 provided in the cover 80 and is pulled out above the cover 80 (see FIG. 5). Thus, the assembly of the electronic component 1-1 is completed. The above assembling procedure is an example, and it goes without saying that the assembly may be performed using other various assembling procedures.

以上のようにして組み立てられた電子部品１−１において、移動体１１０をスライド移動させると、移動体１１０は湾曲するフレキシブル回路基板５０の外周面に沿うように移動し、摺動子１３０の摺動冊子１３３が摺接パターン５５，５７上を摺動し、これによって引出部６５に引き出されている各端子部７１間の検出出力が変化する。移動体１１０はこれを３６０°以上、エンドレスでスライド移動させることができる。すなわち、基板取付面１１を構成する３６０°ある外周面を全て利用して検出出力を得ることができる。 In the electronic component 1-1 assembled as described above, when the movable body 110 is slid, the movable body 110 moves along the outer peripheral surface of the flexible circuit board 50 that is curved, and the slider 130 slides. The booklet 133 slides on the sliding contact patterns 55 and 57, and the detection output between the terminal portions 71 drawn to the drawing portion 65 changes accordingly. The moving body 110 can slide the endlessly by 360 ° or more. That is, the detection output can be obtained by using all the 360 ° outer peripheral surfaces constituting the substrate mounting surface 11.

以上説明したように、上記電子部品１−１はその構造が簡単で、容易に製造・組み立てができる。また上記電子部品１−１において、第１，第２レール部１７，８５の内、一方の第１レール部１７のみを基台１０の一方の端辺１３側に設け、他方の第２レール部８５は別部材であるカバー８０に設けたので、上述のように、１８０°以上の円弧からなる基板取付面１１を有する基台１０を容易に製造することが可能になる。即ち、仮に、基板取付面１１に対してその円弧の中心から外方向に向かって突出するように形成する第１，第２レール部１７，８５を基台１０の両端辺１３，２１側に一体成型で設け、且つ基台１０を円弧状に成形するとした場合は、円弧が１８０°を超えると、その成形が金型上困難になるが、この電子部品１−１に用いる基台１０及びカバー８０の場合はそのような問題は生じない。これによって移動体１１０の移動範囲（摺動子１３０の摺動範囲）を容易に１８０°以上とすることができる。 As described above, the electronic component 1-1 has a simple structure and can be easily manufactured and assembled. Further, in the electronic component 1-1, only one of the first and second rail portions 17 and 85 is provided on one end 13 side of the base 10, and the other second rail portion is provided. Since 85 is provided on the cover 80 which is a separate member, as described above, the base 10 having the substrate mounting surface 11 formed of an arc of 180 ° or more can be easily manufactured. That is, the first and second rail portions 17 and 85 formed so as to protrude outwardly from the center of the arc with respect to the board mounting surface 11 are integrally formed on both side sides 13 and 21 side of the base 10. In the case where the base 10 is formed in an arc shape by molding, if the arc exceeds 180 °, the molding becomes difficult on the mold, but the base 10 and the cover used for the electronic component 1-1 are covered. In the case of 80, such a problem does not occur. Thereby, the moving range of the moving body 110 (sliding range of the slider 130) can be easily set to 180 ° or more.

また、基台１０の一方の端辺１３に基台１０の外周面に対して中心から外方に向かって突出する第１レール形成部１５を設け、一方カバー８０にこのカバー８０を基台１０の他方の端辺２１に取り付けた際に基台１０の外周面に対して中心から外方に向かって突出する第２レール形成部８６を設け、第１，第２レール形成部１５，８６の対向する側の面にそれぞれ第１，第２レール部１７，８５を形成したので、移動体１１０全体をフレキシブル回路基板５０の外周側露出面よりも半径方向外側に位置させることができ、３６０°にわたって回転する移動体１１０にフレキシブル回路基板５０（特にフレキシブル回路基板５０の引出部６５の部分）が干渉することを容易に避けることができる。 In addition, a first rail forming portion 15 that protrudes outward from the center with respect to the outer peripheral surface of the base 10 is provided on one end side 13 of the base 10, and the cover 80 is attached to the base 10. A second rail forming portion 86 that protrudes outward from the center with respect to the outer peripheral surface of the base 10 when attached to the other end side 21 of the first and second rail forming portions 15, 86. Since the first and second rail portions 17 and 85 are formed on the opposing surfaces, respectively, the entire moving body 110 can be positioned radially outward from the outer peripheral side exposed surface of the flexible circuit board 50. It is possible to easily avoid interference of the flexible circuit board 50 (particularly, the portion of the lead-out portion 65 of the flexible circuit board 50) with the moving body 110 that rotates over the entire area.

また上記電子部品１−１においては、移動体１１０の係止部１１９を、この移動体１１０の前後左右の４箇所に設けてこれら４箇所において第１，第２レール部１７，８５に係合する構造なので、例え第１，第２レール部１７，８５が円弧状に湾曲していても、移動体１１０の円弧状の移動をスムーズにガイドすることができる。即ち、第１，第２レール部１７，８５は円弧状に湾曲しているので、移動体１１０の両側辺全体をこれら第１，第２レール部１７，８５に挿入すると、これを円弧状に移動する際に摩擦抵抗が大きくなって移動体１１０のスムーズな移動が阻害される恐れがあるが、この電子部品１−１によれば、移動体１１０の移動方向の前後左右の４箇所に設けた係止部１１９を第１，第２レール部１７，８５に係合するので、移動体１１０を円弧状に移動する際の摩擦抵抗が少なく、移動体１１０をスムーズに移動させることができる。 Further, in the electronic component 1-1, the locking portions 119 of the moving body 110 are provided at four positions on the front and rear, left and right of the moving body 110, and are engaged with the first and second rail portions 17 and 85 at these four positions. Therefore, even if the first and second rail portions 17 and 85 are curved in an arc shape, the moving motion of the moving body 110 can be smoothly guided. That is, since the first and second rail portions 17 and 85 are curved in an arc shape, when the entire sides of the movable body 110 are inserted into the first and second rail portions 17 and 85, the first and second rail portions 17 and 85 are arcuately formed. When moving, there is a risk that the frictional resistance becomes large and the smooth movement of the moving body 110 may be hindered. According to this electronic component 1-1, the moving body 110 is provided at four locations on the front, rear, left and right in the moving direction. Since the engaging portion 119 is engaged with the first and second rail portions 17 and 85, there is little frictional resistance when the moving body 110 is moved in an arc shape, and the moving body 110 can be moved smoothly.

図８は本発明の第２実施形態に係る電子部品１−２の斜視図、図９は電子部品１−２を下側から見た斜視図、図１０はフレキシブル回路基板５０−２の斜視図、図１１は図８のＣ−Ｃ部分断面拡大図、図１２は図８のＤ−Ｄ部分断面拡大図である。これらの図に示す電子部品１−２において、前記図１〜図７に示す電子部品１−１と同一又は相当部分には同一符号を付す（但し、各符号には添え字「−２」を付す）。なお以下で説明する事項以外の事項については、前記図１〜図７に示す電子部品１−１と同じである。 8 is a perspective view of the electronic component 1-2 according to the second embodiment of the present invention, FIG. 9 is a perspective view of the electronic component 1-2 viewed from below, and FIG. 10 is a perspective view of the flexible circuit board 50-2. 11 is an enlarged view of the CC partial cross section of FIG. 8, and FIG. 12 is an enlarged view of the DD partial cross section of FIG. In the electronic component 1-2 shown in these drawings, the same or corresponding parts as those of the electronic component 1-1 shown in FIGS. Attached). Note that matters other than those described below are the same as those of the electronic component 1-1 shown in FIGS.

この電子部品１−２において、上記電子部品１−１と相違する点は、フレキシブル回路基板５０−２を基台１０−２にインサート成形によって取り付けた点のみである。即ちこの電子部品１−２の場合、図１０に示すように、フレキシブル回路基板５０−２の基板本体部５１ａ−２の下側の端辺（一方の端辺）６１−２全体を、前記図３に示すフレキシブル回路基板５０の下側の端辺６１よりも下方に突出し、突出した帯状部分を埋設部７３−２として構成している。なお上述のように、フレキシブル回路基板５０−２は、何ら外力が加わっていない時は、湾曲しておらず、平面状の状態となっている（つまり円弧状にするためのプレフォーミングは行わない）。 The electronic component 1-2 is different from the electronic component 1-1 only in that the flexible circuit board 50-2 is attached to the base 10-2 by insert molding. That is, in the case of this electronic component 1-2, as shown in FIG. 10, the lower end side (one end side) 61-2 of the board main body 51a-2 of the flexible circuit board 50-2 is entirely shown in FIG. 3 protrudes downward from the lower edge 61 of the flexible circuit board 50 shown in FIG. 3, and the protruding belt-like portion is configured as an embedded portion 73-2. Note that, as described above, the flexible circuit board 50-2 is not curved and is in a flat state when no external force is applied (that is, pre-forming for making an arc shape is not performed). ).

そして基台１０−２を成形する際に、その金型のリング状のキャビティー内部にフレキシブル回路基板５０−２を湾曲させながら挿入し、その際キャビティーの外側の内周面にフレキシブル回路基板５０−２の表面側（摺接パターン５５−２，５７−２を設けた面側）を対向させる。次に、前記フレキシブル回路基板５０−２の裏面側に対向するキャビティーの内側の内周面に所定間隔毎に設けた複数のゲートから溶融樹脂をフレキシブル回路基板５０−２の裏面に向けて射出する。これによって、フレキシブル回路基板５０−２は外方に押し広げられ、フレキシブル回路基板５０−２の表面がキャビティーの外側の内周面に押し付けられながら溶融樹脂の充填が進み、同時に、図１１，図１２に示すように、フレキシブル回路基板５０−２の一方の端辺６１−２（埋設部７３−２）は、基台１０−２内に埋設するようにインサート成形される。このように、ゲートはフレキシブル回路基板５０−２の裏面側に対向して設けるのが好ましい。 Then, when the base 10-2 is molded, the flexible circuit board 50-2 is inserted into the ring-shaped cavity of the mold while being bent, and at that time, the flexible circuit board is placed on the inner peripheral surface outside the cavity. The surface side of 50-2 (the surface side on which the sliding contact patterns 55-2 and 57-2 are provided) is opposed. Next, molten resin is injected toward the back surface of the flexible circuit board 50-2 from a plurality of gates provided at predetermined intervals on the inner peripheral surface of the cavity facing the back surface side of the flexible circuit board 50-2. To do. As a result, the flexible circuit board 50-2 is spread outward, and the filling of the molten resin proceeds while the surface of the flexible circuit board 50-2 is pressed against the outer peripheral surface of the cavity. As shown in FIG. 12, one end 61-2 (embedded portion 73-2) of the flexible circuit board 50-2 is insert-molded so as to be embedded in the base 10-2. Thus, it is preferable that the gate is provided to face the back side of the flexible circuit board 50-2.

これによって、フレキシブル回路基板５０−２は基台１０−２の基板取付面１１−２に密着して強固に取り付けられる。このように構成すれば、インサート成形によって、容易且つ確実にフレキシブル回路基板５０−２の一方の端辺６１−２（埋設部７３−２）を基台１０−２内に埋設して固定することができ、このフレキシブル回路基板５０−２を基台１０−２の基板取付面１１−２に取り付けることができる。同時に、基板取付面１１−２のフレキシブル回路基板５０−２が位置しない面は、フレキシブル回路基板５０−２の表面と同一面となる（言い換えればフレキシブル回路基板５０−２は基板取付面１１−２内に埋設されている）。このため、リング状となっているフレキシブル回路基板５０−２の両端部間の隙間部分の表面とフレキシブル回路基板５０−２の表面とが同一面となり、摺動子１１０−２を３６０°以上回転するような場合でも前記隙間部分に段差（凹凸）が生じず、スムーズな移動が行え、信頼性が向上する。 As a result, the flexible circuit board 50-2 is firmly attached in close contact with the board attachment surface 11-2 of the base 10-2. If comprised in this way, one edge 61-2 (embedding part 73-2) of the flexible circuit board 50-2 will be embed | buried in the base 10-2 and fixed easily and reliably by insert molding. The flexible circuit board 50-2 can be attached to the board attachment surface 11-2 of the base 10-2. At the same time, the surface of the board mounting surface 11-2 where the flexible circuit board 50-2 is not located is the same as the surface of the flexible circuit board 50-2 (in other words, the flexible circuit board 50-2 is mounted on the board mounting surface 11-2). Embedded in). For this reason, the surface of the clearance between both ends of the flexible circuit board 50-2 that is ring-shaped and the surface of the flexible circuit board 50-2 are flush with each other, and the slider 110-2 is rotated 360 ° or more. Even in such a case, a step (unevenness) does not occur in the gap portion, smooth movement can be performed, and reliability is improved.

また上述のように、フレキシブル回路基板５０−２はプレフォーミングしないまま直接撓めてキャビティー内に挿入して成形するので、フレキシブル回路基板５０−２がプレフォーム時に伸びて摺接パターン５５−２，５７−２が引き延ばされて破断などするといった問題を防止できる。 In addition, as described above, the flexible circuit board 50-2 is directly bent without being preformed and inserted into the cavity to be molded, so that the flexible circuit board 50-2 extends at the time of preforming and the sliding contact pattern 55-2. , 57-2 can be stretched and broken.

なおその他の構成、組立方法、作用効果は、何れも上記電子部品１−１と同様なので、それらの説明は省略する。 Since other configurations, assembling methods, and operational effects are all the same as those of the electronic component 1-1, description thereof will be omitted.

以上本発明の実施形態を説明したが、本発明は上記実施形態に限定されるものではなく、特許請求の範囲、及び明細書と図面に記載された技術的思想の範囲内において種々の変形が可能である。なお直接明細書及び図面に記載がない何れの形状や構造や材質であっても、本願発明の作用・効果を奏する以上、本願発明の技術的思想の範囲内である。例えば、上記例では摺接パターンを一対設けたが、１本または３本以上であっても良い。また上記例では摺接パターンとして、抵抗体パターンと導体パターンを用いたが、スイッチパターン等、他の各種用途に用いるパターンを用いても良い。 Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea described in the claims and the specification and drawings. Is possible. Note that any shape, structure, or material not directly described in the specification and drawings is within the scope of the technical idea of the present invention as long as the effects and advantages of the present invention are exhibited. For example, although a pair of sliding contact patterns is provided in the above example, one or three or more may be used. In the above example, the resistor pattern and the conductor pattern are used as the sliding contact pattern. However, a pattern used for various other purposes such as a switch pattern may be used.

また上記例では、移動体を３６０°以上、エンドレスで移動できるように構成したが、何れかの位置にストッパ部などを設けることで、３６０°以下の所望の角度範囲で移動できるように構成しても良い。その際、移動する角度に応じてフレキシブル回路基板の長さを短くしても良い。また図１１に点線で示すように、基台とカバーの第１，第２レール部の外側の壁面部分を相互に接近するように延ばして移動体の操作部のみを外部に突出するように構成すれば、摺接パターンや摺動子からなる検出手段の部分の防塵効果を向上させることができる。 In the above example, the movable body is configured to be movable endlessly at 360 ° or more. However, by providing a stopper portion or the like at any position, the movable body is configured to be movable within a desired angle range of 360 ° or less. May be. At this time, the length of the flexible circuit board may be shortened according to the moving angle. Further, as shown by a dotted line in FIG. 11, the base and the outer wall surfaces of the first and second rail portions of the cover are extended so as to approach each other, and only the operation portion of the moving body protrudes to the outside. If it does so, the dust-proof effect of the part of the detection means which consists of a sliding contact pattern or a slider can be improved.
