Description

本発明は、操作つまみを揺動（回転）することでその電気的出力を変化する回転式電子部品に関するものである。 The present invention relates to a rotary electronic component that changes its electrical output by swinging (rotating) an operation knob.

従来回転式電子部品の中には、所望の摺接パターンを設けた基板の面に対向して揺動自在に揺動体（回転体）を設置し、この揺動体に設けた摺動子を前記基板の摺接パターンに摺接させることでその電気的出力を変化させる構造とし、さらに前記揺動体の上部に別途人の指等によって操作される操作つまみを取り付ける構造のものがあった（例えば特許文献１参照）。 In a conventional rotary electronic component, a swinging body (rotating body) is installed so as to be swingable so as to face the surface of a substrate provided with a desired sliding contact pattern, and the slider provided on the swinging body is connected to the above-described sliding body. There is a structure in which the electrical output is changed by sliding contact with the sliding contact pattern of the substrate, and an operation knob that is separately operated by a human finger or the like is attached to the upper part of the oscillator (for example, patent) Reference 1).

しかしながら上記従来の回転式電子部品においては、操作つまみの揺動体への取り付けが、揺動体の上部外周から突出する１つの突起を操作つまみに設けた穴に圧入することのみによって行われていたので、必ずしもその取付強度は強くなく、操作つまみが揺動体から容易に外れてしまう恐れがあった。上記問題は特に回転式電子部品が小型化した場合に顕著となる。
特開２００５−１９８４４号公報 However, in the conventional rotary electronic component, the operation knob is attached to the rocking body only by press-fitting one protrusion protruding from the upper outer periphery of the rocking body into the hole provided in the operation knob. However, the mounting strength is not necessarily strong, and the operation knob may be easily detached from the rocking body. The above problem is particularly noticeable when the rotary electronic component is downsized.

The press-fitting engagement portion 109 is formed in a size and shape that is press-fitted into a press-fitting engagement portion 57 provided on the rocking body 50. The shape of the locking piece 107 is the same as that of the locking piece 105, that is, a longer length is suitable for giving elasticity. However, in the case of this embodiment, since the case fixing portion 151 of the mounting member 150 described below is installed on the second case 30 side where the locking piece 107 is installed, there is no space extending downward, so that it is positioned at the top. It is installed short. In order to give elasticity to the short locking piece 107 as compared with the locking piece 105, the lateral width is increased.

次にこの回転式電子部品１−１の組立方法を説明する。まず予め揺動体５０の電気的機能部設置部６５に摺動子８０の基部８１を当接し、その際基部８１の小孔８７に小突起６９を挿入してその先端を熱カシメして固定する。一方揺動体５０のコイル収納部５４に両端にバネ受９１を取り付けたコイルスプリング９０を収納しておく。一方第２ケース３０の基板設置部３１にフレキシブル回路基板１３０のパターン形成部１３１を収納し、その際パターン形成部１３１の一対の取付部１３５にそれぞれ第２ケース３０の基板取付部３３を挿入し、その先端を熱カシメすることによって両者を一体化する。 Next, a method for assembling the rotary electronic component 1-1 will be described. First, the base part 81 of the slider 80 is previously brought into contact with the electrical function part installation part 65 of the rocking body 50, and at that time, a small protrusion 69 is inserted into the small hole 87 of the base part 81, and the tip is thermally crimped and fixed. . On the other hand, a coil spring 90 with spring receivers 91 attached to both ends is stored in the coil storage portion 54 of the rocking body 50. On the other hand, the pattern forming portion 131 of the flexible circuit board 130 is accommodated in the substrate mounting portion 31 of the second case 30, and the substrate mounting portions 33 of the second case 30 are respectively inserted into the pair of mounting portions 135 of the pattern forming portion 131. Integrate the two by caulking the tip.

そして前記摺動子８０とコイルスプリング９０を取り付けた揺動体５０を、第１ケース１０の収納部１３内に収納し、次にその後方からフレキシブル回路基板１３０を取り付けた第２ケース３０を被せ、その際第１ケース１０の位置決め穴２５に第２ケース３０の位置決め部３７を挿入する。そして第２ケース３０の後方に取付部材１５０のケース固定部１５１を当接し、その際ケース固定部１５１の挿入部１５５に第２ケース３０のガイド部３９を挿入し、位置決めする。そしてこのとき取付部材１５０の両固定部１５７は第２ケース３０と第１ケース１０の両側部を通って第１ケース１０の前方に突出するので、その先端を第１ケース１０の前面（第２ケース３０を接合する面の反対側の面）に折り曲げ、これによって第１，第２ケース１０，３０を一体に固定する。そして一体化した第１，第２ケース１０，３０の上部に操作つまみ１００を設置し、その際操作つまみ１００の圧入係合部１０９を揺動体５０の圧入係合部５７に圧入し、このとき同時に操作つまみ１００の両係止片１０５，１０７の係止部１１１，１１５にそれぞれ揺動体５０の第１係止突起５９の爪部６１及び第２係止突起６７の爪部７１をスナップイン係合する。両係止片１０５，１０７は何れも弾性を有しており、しかも両係止片１０５，１０７の先端部と両爪部６１，７１とにはそれぞれテーパ面６３，７３，１１３，１１７が設けられているので、これらテーパ面６３，７３，１１３，１１７同士が当接することで容易に両係止片１０５，１０７が外方に撓み、容易にスナップイン係合させることができる。つまり操作つまみ１００は、第１，第２ケース１０，３０の外方に設置され揺動体５０に連結されて揺動体５０と一体に揺動する。なおこの実施形態においては、揺動体５０と操作つまみ１００との結合は主として両圧入係合部５７，１０９によって行われる。一方両係止片１０５，１０７と第１，第２係止突起５９，６７との係合には所定の遊びがあり、これらの係合は主として操作つまみ１００が揺動体５０から外れないように（抜け防止用に）用いられている。またこのとき、第１ケース１０に設けた両コイル係止部１９の先端に、それぞれバネ受９１の端面が当接している。 Then, the swinging body 50 to which the slider 80 and the coil spring 90 are attached is housed in the housing portion 13 of the first case 10, and then the second case 30 to which the flexible circuit board 130 is attached is covered from behind. At that time, the positioning portion 37 of the second case 30 is inserted into the positioning hole 25 of the first case 10. Then, the case fixing portion 151 of the mounting member 150 is brought into contact with the rear of the second case 30. At this time, the guide portion 39 of the second case 30 is inserted into the insertion portion 155 of the case fixing portion 151 and positioned. At this time, the two fixing portions 157 of the mounting member 150 protrude through the second case 30 and both side portions of the first case 10 to the front of the first case 10, so that the tip of the fixing member 157 is the front surface of the first case 10 (second The case 30 is bent to a surface opposite to the surface to which the case 30 is joined, whereby the first and second cases 10 and 30 are fixed together. Then, the operation knob 100 is installed on the upper portions of the integrated first and second cases 10 and 30. At this time, the press-fitting engagement portion 109 of the operation knob 100 is press-fitted into the press-fitting engagement portion 57 of the oscillating body 50. At the same time, the claw portion 61 of the first locking projection 59 and the claw portion 71 of the second locking projection 67 of the swinging body 50 are snapped into the locking portions 111 and 115 of the both locking pieces 105 and 107 of the operation knob 100, respectively. Match. Both the locking pieces 105 and 107 have elasticity, and the tip portions of the locking pieces 105 and 107 and the claw portions 61 and 71 are provided with tapered surfaces 63, 73, 113, and 117, respectively. Therefore, when these taper surfaces 63, 73, 113, 117 are brought into contact with each other, both the locking pieces 105, 107 are easily bent outward and can be easily snap-in engaged. That is, the operation knob 100 is installed outside the first and second cases 10 and 30, is connected to the swing body 50, and swings integrally with the swing body 50. In this embodiment, the coupling between the rocking body 50 and the operation knob 100 is mainly performed by the both press-fitting engagement portions 57 and 109. On the other hand, there is a predetermined play in the engagement between both the locking pieces 105 and 107 and the first and second locking protrusions 59 and 67, and these engagements mainly prevent the operation knob 100 from being detached from the swinging body 50. Used for preventing omission. At this time, the end surfaces of the spring receivers 91 are in contact with the tips of the two coil locking portions 19 provided in the first case 10.

以上のように構成された回転式電子部品１−１において、操作つまみ１００を揺動すると、これと一体に揺動体５０が揺動体５０の揺動中心軸（前述のように揺動中心軸は第１ケース１０の中央から真下に向かって所定距離下降した位置にある）を中心に揺動し、これによって摺動子８０が摺接パターン１３７上を摺動し、端子パターン１３９の電気的出力を変化する。このように操作つまみ１００を中立位置から揺動させた際、これと一体に揺動した揺動体５０の一方の挿通部５５に第１ケース１０の一方のコイル係止部１９がコイル収納部５４内に入り込み、コイルスプリング９０の一方のバネ受９１を押圧してコイルスプリング９０をコイル収納部５４内で圧縮し、中立位置への自動復帰力が生じる。従って操作つまみ１００の揺動を解除すれば、操作つまみ１００は元の中立位置に自動復帰し、電気的出力も元の中立位置の出力となる。 In the rotary electronic component 1-1 configured as described above, when the operation knob 100 is swung, the swinging body 50 is integrated with the swinging center axis of the swinging body 50 (the swinging center axis is as described above). The slider 80 is slid on the sliding contact pattern 137 so that the electrical output of the terminal pattern 139 is obtained. Change. When the operation knob 100 is swung from the neutral position as described above, one coil locking portion 19 of the first case 10 is connected to the coil housing portion 54 in one insertion portion 55 of the swinging body 50 that swings integrally therewith. The coil spring 90 is pressed into the coil housing portion 54 by pressing one spring receiver 91 of the coil spring 90, and an automatic return force to the neutral position is generated. Therefore, when the swing of the operation knob 100 is released, the operation knob 100 automatically returns to the original neutral position, and the electrical output is also the output of the original neutral position.

図８は上記回転式電子部品１−１に他の回路基板（以下「フレキシブル回路基板」という）１７０を機械的・電気的に接続する接続構造の１例を示す概略側断面図である。同図に示す接続構造は、取付部材１５０の押え部１５３の下面側にフレキシブル回路基板１３０の端子パターン部１３３を設置し、その下側に他のフレキシブル回路基板１７０を設置し、その下側に取付台１８０を設置する。フレキシブル回路基板１７０の上面にはフレキシブル回路基板１３０の各端子パターン１３９にそれぞれ接続される図示しない端子パターンが設けられており、対向するそれぞれの端子パターン同士が直接当接している。フレキシブル回路基板１７０に設けた各端子パターンは図示しない回路パターンによってフレキシブル回路基板１７０の図示しない各種電子部品を搭載した所定の場所まで引き出されている。取付台１８０はこの実施形態では合成樹脂製の略平板であり、その上面の前記端子パターン１３９に対向する位置に凹状の弾発部材収納部１８１が設置され、その中に弾性金属板からなる弾発部材１８３が収納され、フレキシブル回路基板１７０の各端子パターンを設けた部分をその裏面側からフレキシブル回路基板１３０の各端子パターン１３９に向けて押圧し圧接している。取付部材１５０と両フレキシブル回路基板１３０，１７０と取付台１８０間の挟持・一体化は、取付部材１５０に設けた取付片１５９を取付台１８０の下面に折り曲げることによって行われる。 FIG. 8 is a schematic sectional side view showing an example of a connection structure for mechanically and electrically connecting another circuit board (hereinafter referred to as “flexible circuit board”) 170 to the rotary electronic component 1-1. In the connection structure shown in the figure, the terminal pattern part 133 of the flexible circuit board 130 is installed on the lower surface side of the holding part 153 of the mounting member 150, the other flexible circuit board 170 is installed on the lower side thereof, and the lower side thereof. A mounting stand 180 is installed. Terminal patterns (not shown) connected to the terminal patterns 139 of the flexible circuit board 130 are provided on the upper surface of the flexible circuit board 170, and the opposing terminal patterns are in direct contact with each other. Each terminal pattern provided on the flexible circuit board 170 is drawn out to a predetermined place on the flexible circuit board 170 on which various electronic components (not shown) are mounted by a circuit pattern (not shown). In this embodiment, the mounting base 180 is a substantially flat plate made of synthetic resin, and a concave elastic member housing portion 181 is installed at a position facing the terminal pattern 139 on the upper surface thereof, and an elastic metal plate is formed therein. The emitting member 183 is accommodated, and the portion of the flexible circuit board 170 provided with each terminal pattern is pressed from the back side toward each terminal pattern 139 of the flexible circuit board 130 to be in pressure contact therewith. The mounting member 150, the flexible circuit boards 130 and 170, and the mounting base 180 are sandwiched and integrated by bending a mounting piece 159 provided on the mounting member 150 to the lower surface of the mounting base 180.

以上説明したようにこの実施形態にかかる回転式電子部品１−１によれば、操作つまみ１００と揺動体５０との連結を、操作つまみ１００と揺動体５０とが対向する対向面に設けた圧入係合部１０９，５７同士を第１，第２ケース１０，３０を介して圧入係合することと、揺動体５０に揺動中心軸方向（揺動中心軸に平行な方向）に沿ってケース側面２７，４１から外方に突出する第１，第２係止突起５９，６７を設け、これら第１，第２係止突起５９，６７を操作つまみ１００からケース側面２７，４１の外側に延設される係止片１０５，１０７に係合させることとによって行なっているので、つまり操作つまみ１００と揺動体５０の連結を３ヶ所で行うので、例え回転式電子部品１−１が小型化されても操作つまみ１００の揺動体５０への取り付けが確実になり、操作つまみ１００の抜けなどの問題が生じなくなる。なお操作つまみ１００と揺動体５０の連結を３ヶ所で行う代りに、第１係止突起５９と係止片１０５との係合と、第２係止突起６７と係止片１０７との係合の何れか一方を省略して２ヶ所としても良い。 As described above, according to the rotary electronic component 1-1 according to this embodiment, the connection between the operation knob 100 and the rocking body 50 is press-fitted on the facing surface where the operation knob 100 and the rocking body 50 face each other. The engagement portions 109 and 57 are press-fitted and engaged with each other via the first and second cases 10 and 30, and the swing body 50 is moved along the swing center axis direction (direction parallel to the swing center axis). First and second locking projections 59 and 67 projecting outward from the side surfaces 27 and 41 are provided, and the first and second locking projections 59 and 67 extend from the operation knob 100 to the outside of the case side surfaces 27 and 41. Since it is performed by engaging with the locking pieces 105 and 107 provided, that is, the operation knob 100 and the rocking body 50 are connected at three positions, for example, the rotary electronic component 1-1 is downsized. Even to the swinging body 50 of the operation knob 100 Mounting is ensured, not cause problems such as omission of the operation knob 100. Instead of connecting the operation knob 100 and the rocking body 50 at three positions, the engagement between the first locking protrusion 59 and the locking piece 105 and the engagement between the second locking protrusion 67 and the locking piece 107 are performed. Any one of the above may be omitted to provide two locations.

またこの実施形態にかかる回転式電子部品１−１によれば、係合片１０５，１０７に弾性を持たせることで、これら係合片１０５，１０７の第１，第２係止突起５９，６７への係合をスナップイン係合構造としたので、操作つまみ１００の圧入係合部１０９と揺動体５０の圧入係合部５７とを圧入係合する際に、同時に操作つまみ１００の係合片１０５，１０７を揺動体５０の第１，第２係止突起５９，６７にスナップイン係合でき、両者の係合が同時に容易に行える。 Further, according to the rotary electronic component 1-1 according to this embodiment, the engagement pieces 105 and 107 are made elastic so that the first and second locking projections 59 and 67 of the engagement pieces 105 and 107 are obtained. Since the snap-in engagement structure is used for the engagement of the operation knob 100, when the press-fitting engagement part 109 of the operation knob 100 and the press-fitting engagement part 57 of the swinging body 50 are press-fitted and engaged, 105 and 107 can be snap-in engaged with the first and second locking projections 59 and 67 of the rocking body 50, and both can be easily engaged simultaneously.

またこの実施形態によれば、一方の第２係止突起６７を、揺動体５０の側面の操作つまみ１００に接近した側（即ち上部）に設けたので、揺動体５０側面の中央に摺動子８０を設置でき、電気的機能部として有効に利用できる。即ち通常の回転式電子部品の場合、揺動体の揺動中心軸は揺動体の中にあり、その中心軸を回路基板に貫通させている。しかしながらこの実施形態の場合、揺動体５０の揺動中心軸は揺動体５０の中にはなく、その外方（下方）にある。このためフレキシブル回路基板１３０のパターン形成部１３１にはその内部において揺動中心軸を貫通させることはなく、この揺動中心軸に操作つまみ１００を係合することはできない（その分パターン形成部１３１の高さは低くでき、小型化が図れる）。そこで本実施形態においては別途揺動体５０から第１，第２の係止突起５９，６７を突出し、これらを操作つまみ１００の係合片１０５，１０７に係合したのであるが、その際、第２の係止突起６７の位置を揺動体５０の側面の中央ではなく、その上部（又は下部）とすることで、揺動体５０の側面中央に摺動子８０を設置できるようにしたのである。同様に第１の係止突起５９を揺動体５０の下部に設置することで揺動体５０の第１の係止突起５９を突出した側の側面中央にコイルスプリング９０を収納できるようにしている。 Further, according to this embodiment, since the one second locking projection 67 is provided on the side close to the operation knob 100 on the side surface of the oscillating body 50 (that is, the upper part), the slider is provided at the center of the side surface of the oscillating body 50. 80 can be installed, and can be used effectively as an electrical function unit. That is, in the case of a normal rotary electronic component, the swinging center axis of the swinging body is in the swinging body, and the center axis is passed through the circuit board. However, in this embodiment, the oscillation center axis of the oscillating body 50 is not in the oscillating body 50 but outside (downward). For this reason, the pattern forming portion 131 of the flexible circuit board 130 does not penetrate the swing center axis in the inside thereof, and the operation knob 100 cannot be engaged with the swing center axis (the pattern forming portion 131 correspondingly). Can be reduced in size and can be downsized). Therefore, in the present embodiment, the first and second locking projections 59 and 67 are separately protruded from the rocking body 50 and engaged with the engaging pieces 105 and 107 of the operation knob 100. The position of the second locking projection 67 is not the center of the side surface of the rocking body 50, but the upper part (or the lower part) thereof, so that the slider 80 can be installed at the center of the side surface of the rocking body 50. Similarly, the first latching protrusion 59 is installed in the lower part of the rocking body 50 so that the coil spring 90 can be accommodated in the center of the side surface of the rocking body 50 on the side where the first latching protrusion 59 protrudes.
