Description

本発明は、回転つまみの回転に適度なねっとりとした粘りのある抵抗を生じさせることができ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 capable of generating a sticky and sticky resistance suitable for rotation of a rotary knob.

従来、回転式電子部品の回転つまみを回転した際のその回転感覚として、適度にねっとりとした粘りのある抵抗を生じさせることが望まれる場合がある。そして従来この種のねっとりとした抵抗を得るためにグリスが用いられてきた。即ちグリスを回転つまみの回転軸とこの回転軸を軸支する固定側部材の軸受との間等に塗布し、このグリスの粘度によって回転つまみの回転時のねっとり感を出すのである（例えば特許文献１）。 Conventionally, as a sense of rotation when a rotary knob of a rotary electronic component is rotated, it may be desired to generate a moderately sticky resistance. Conventionally, grease has been used to obtain this kind of sticky resistance. That is, grease is applied between the rotary shaft of the rotary knob and the bearing of the fixed side member that supports the rotary shaft, and the viscosity of the grease gives a sticky feeling when the rotary knob is rotated (for example, Patent Documents). 1).

しかしながら、前記ねっとりとした抵抗として大きな抵抗が望まれる場合、前記グリスの粘度を高くする必要があるが、グリスの粘度を高くすると、この回転式電子部品を低温の雰囲気内に設置した場合、グリスが硬くなり過ぎ、必要以上の回転抵抗が生じてしまう。一方低温時を考慮してグリスの粘度を低くすると、常温又は高温の雰囲気内では逆に回転抵抗が小さくなり過ぎてしまう。
特開２００４−１７２００７号公報 However, when a large resistance is desired as the sticky resistance, it is necessary to increase the viscosity of the grease. However, if the viscosity of the grease is increased, when the rotary electronic component is installed in a low temperature atmosphere, the grease Becomes too hard, and unnecessarily rotational resistance is generated. On the other hand, if the viscosity of the grease is lowered in consideration of the low temperature, the rotational resistance becomes too small in a normal temperature or high temperature atmosphere.

And a rotating knob attached to the shaft member protruding from the upper surface of the case, and the rotating member rotates the shaft member and the rotating body integrally with the rotating knob, thereby the electric function portion.

本願請求項２に記載の発明は、前記抵抗付与部は、同心円筒上に位置する複数の円弧状板部材によって構成されていることを特徴とする請求項１に記載の回転式電子部品にある。 The invention according to claim 2 of the present application resides in the rotary electronic component according to claim 1, wherein the resistance applying portion is configured by a plurality of arc-shaped plate members positioned on concentric cylinders. .

The rotary electronic component according to claim 1, wherein the electrical function unit is installed on a surface side.

請求項１に記載の発明によれば、グリスによってねっとり感を出す抵抗（グリス抵抗）と、弾接部材によって回転体の回転に付与される抵抗（弾接抵抗）とを同時に負荷したので、温度によって変化しない弾接抵抗によって、温度によって変化するグリス抵抗の変化を相対的に小さくできる。
またグリス抵抗は、グリス充填部に充填されたグリス内に抵抗付与部を挿入することによって付与されるので、単に回転つまみの回転軸とその軸受の間にグリスを塗布する場合に比べて、十分なグリスによってグリス抵抗を付与でき、従来に比べてさらに十分なねっとり感が得られるばかりか、大きな抵抗が得られる。
つまり本発明によれば、従来に比べてさらに十分なねっとり感が得られるので、例え弾接抵抗によってグリス抵抗が相対的に小さくなってもねっとり感としては十分なものが得られ、同時に温度によってねっとり感に変化は出るものの弾接抵抗によって回転抵抗が大きく変化することはなく、従って両抵抗のバランスを図ることで、回転つまみの回転時に適度なねっとりとした抵抗が得られると共にその抵抗が温度による影響を受け難い回転式電子部品が得られる。 According to the first aspect of the present invention, the resistance (grease resistance) that gives a sticky feeling by the grease and the resistance (elastic contact resistance) applied to the rotation of the rotating body by the elastic contact member are simultaneously loaded. The change in grease resistance that changes with temperature can be made relatively small by the elastic contact resistance that does not change with temperature.
Also, the grease resistance is given by inserting a resistance imparting part into the grease filled in the grease filling part, so that it is sufficient compared to simply applying grease between the rotary shaft of the rotary knob and its bearing. Grease resistance can be imparted by simple grease, and not only a more dull feeling can be obtained compared to the conventional case, but also a large resistance can be obtained.
In other words, according to the present invention, it is possible to obtain a more dull feeling compared to the conventional case, so that even if the grease resistance is relatively small due to the ballistic resistance, a dull feeling can be obtained, and at the same time, depending on the temperature. Although there is a change in the feeling of stickiness, the rotational resistance does not change significantly due to the ballistic resistance, so by balancing the two resistances, a moderately sticky resistance can be obtained when the rotary knob is rotated, and the resistance is the temperature. A rotary electronic component that is not easily affected by the above can be obtained.

請求項２に記載の発明によれば、抵抗付与部を構成する複数の円弧状板部材によってグリス充填部内に充填したグリスを攪拌するので、隣り合う円弧状板部材間の隙間に充填されているグリスが掻き回され、グリスの粘性を効率的に十分に回転つまみに伝達できる。この構成はねっとりとした強い抵抗を付与するのに好適である。 According to the second aspect of the present invention, the grease filled in the grease filling portion is stirred by the plurality of arc-shaped plate members constituting the resistance applying portion, so that the gap between the adjacent arc-shaped plate members is filled. The grease is stirred, and the viscosity of the grease can be efficiently and sufficiently transmitted to the rotary knob. This configuration is suitable for giving a strong and strong resistance.

請求項３に記載の発明によれば、グリス充填部から十分離れた位置に電気的機能部を設置したので、グリスが電気的機能部に達することを容易に防止できる。 According to the third aspect of the present invention, since the electrical function part is installed at a position sufficiently away from the grease filling part, it is possible to easily prevent the grease from reaching the electrical function part.

図２に示す２２０は所望の粘度を有するグリスであり、グリス２２０は以下で説明するように、ケース１２０のグリス充填部１３５に適量が充填される。 2 is grease having a desired viscosity, and an appropriate amount of the grease 220 is filled in the grease filling portion 135 of the case 120 as described below.

次に回転式電子部品１の組立方法を説明する。まず予め回転体７０の上面に補強板１００を載置し、その際回転体７０の各取付片７７を補強板１００の各取付固定部１０３に挿入して各取付片７７の先端を熱かしめして取り付ける。一方回転体７０の下面に摺動子８０を設置し、その際回転体７０の各摺動子取付部７９を摺動子８０の各固定部８９に挿入して各摺動子取付部７９の先端を熱かしめして取り付ける。またケース１２０の上面部１２５の裏面に弾接バネ１１０を設置し、その際上面部１２５の裏面に設けた図示しない一対の小突起を弾接バネ１１０に設けた一対の挿入固定部１１３にそれぞれ挿入して前記小突起の先端を熱かしめして取り付ける。またケース１２０のグリス充填部１３５にその開口部１３５ａから予め所定量のグリス２２０を充填する。また弾接バネ１１０にもグリスを塗布しておく。 Next, a method for assembling the rotary electronic component 1 will be described. First, the reinforcing plate 100 is placed on the upper surface of the rotating body 70 in advance, and at that time, the mounting pieces 77 of the rotating body 70 are inserted into the mounting fixing portions 103 of the reinforcing plate 100 and the tips of the mounting pieces 77 are heat staked. And attach. On the other hand, the slider 80 is installed on the lower surface of the rotating body 70, and at that time, each slider mounting portion 79 of the rotating body 70 is inserted into each fixing portion 89 of the slider 80, and Attach the tip with heat. Further, the elastic contact spring 110 is installed on the back surface of the upper surface portion 125 of the case 120, and a pair of small protrusions (not shown) provided on the back surface of the upper surface portion 125 are provided on the pair of insertion fixing portions 113 provided on the elastic contact spring 110. Insert and insert the tip of the small protrusion by heat caulking. Further, a predetermined amount of grease 220 is filled in the grease filling portion 135 of the case 120 through the opening 135a. In addition, grease is also applied to the elastic contact spring 110.

そして軸部材１５０の上に押釦つまみ１８０を設置し、その際押釦つまみ１８０の軸部１８３を軸部材１５０の挿通部１５５に上下動自在に挿入し、押釦つまみ１８０のつまみ部１８１を軸部材１５０のつまみ部収納部１６７内に収納し、同時に押釦つまみ１８０の位置決め部１８９を軸部材１５０のつまみ位置決め部１６９に係合して軸部材１５０に対して押釦つまみ１８０が回転しないようにする。 Then, the push button knob 180 is installed on the shaft member 150. At that time, the shaft portion 183 of the push button knob 180 is inserted into the insertion portion 155 of the shaft member 150 so as to be movable up and down, and the knob portion 181 of the push button knob 180 is inserted into the shaft member 150. And the positioning portion 189 of the push button knob 180 is simultaneously engaged with the knob positioning portion 169 of the shaft member 150 so that the push button knob 180 does not rotate with respect to the shaft member 150.

次に押釦つまみ１８０を装着した軸部材１５０の上に回転つまみ２００を被せ、軸部材１５０の上部を回転つまみ２００の軸部材収納部２０７内に収納する。その際回転つまみ２００の各係合部２０９を軸部材１５０の各被係合部１６３に、回転つまみ２００の回転中心軸Ｌ方向にスライドして係合させる。同時に回転つまみ２００の位置決め部２１１を軸部材１５０の位置決め部１６５に、回転つまみ２００の回転中心軸Ｌ方向にスライドして係合させる。なおこのとき軸部材１５０の上端面は回転つまみ２００の上面部２０３の裏面に当接し、この当接した位置（スライド方向の位置）に位置決めされる。またこのとき各係合部２０９の下端２０９ａは、被係合部１６３の下端（つまみ固定部１５３の下面）から少し突出（露出）する。そして突出（露出）した各係合部２０９の下端２０９ａを図１に示すように熱かしめして潰し、これによって係合部２０９と被係合部１６３とを固定し、回転つまみ２００と軸部材１５０とを一体化する。 Next, the rotary knob 200 is placed on the shaft member 150 on which the push button knob 180 is mounted, and the upper portion of the shaft member 150 is stored in the shaft member storage portion 207 of the rotary knob 200. At that time, the respective engaging portions 209 of the rotary knob 200 are slid and engaged with the respective engaged portions 163 of the shaft member 150 in the direction of the rotation center axis L of the rotary knob 200. At the same time, the positioning portion 211 of the rotary knob 200 is slid and engaged with the positioning portion 165 of the shaft member 150 in the direction of the rotation center axis L of the rotary knob 200. At this time, the upper end surface of the shaft member 150 abuts on the back surface of the upper surface portion 203 of the rotary knob 200 and is positioned at this abutting position (slide direction position). At this time, the lower end 209a of each engaging portion 209 slightly protrudes (exposes) from the lower end of the engaged portion 163 (the lower surface of the knob fixing portion 153). Then, the lower end 209a of each protruding (exposed) engaging portion 209 is crushed by heat caulking as shown in FIG. 1, thereby fixing the engaging portion 209 and the engaged portion 163, and the rotary knob 200 and the shaft member. 150 is integrated.

次に押釦つまみ１８０及び回転つまみ２００を一体化した軸部材１５０の軸部本体１５１の外表面、又はケース１２０の軸受孔１２９の内表面にグリスを塗布した上で、前記軸部材１５０をケース１２０上に配置し、軸部材１５０の軸部本体１５１をケース１２０の軸受孔１２９に回動自在に挿入する。このとき同時にグリス充填部１３５に充填されているグリス２２０内にグリス充填部１３５の開口部１３５ａから軸部材１５０に設けた抵抗付与部１５９が挿入される。 Next, after applying grease to the outer surface of the shaft body 151 of the shaft member 150 or the inner surface of the bearing hole 129 of the case 120, the shaft member 150 is integrated with the case 120. The shaft portion main body 151 of the shaft member 150 is rotatably inserted into the bearing hole 129 of the case 120. At the same time, the resistance applying portion 159 provided on the shaft member 150 is inserted into the grease 220 filled in the grease filling portion 135 from the opening 135 a of the grease filling portion 135.

次にケース１２０の下面側からその収納部１２７内に、補強板１００と摺動子８０とを取り付けた回転体７０を収納し、軸部材１５０下端の各取付係合部１５７を回転体７０の各取付穴７３に挿入し、回転体７０の下面から突出する各取付係合部１５７を熱かしめして軸部材１５０と回転体７０とを一体化する。 Next, the rotating body 70 to which the reinforcing plate 100 and the slider 80 are attached is housed in the housing portion 127 from the lower surface side of the case 120, and each mounting engagement portion 157 at the lower end of the shaft member 150 is attached to the rotating body 70. The shaft member 150 and the rotating body 70 are integrated by inserting each mounting hole 73 and heat-caulking each mounting engaging portion 157 protruding from the lower surface of the rotating body 70.

次にケース１２０の下面にフレキシブル回路基板２０の回転式電子部品部４５を配置し、その下側に支持台６０を設置し、その際ケース１２０の各取付固定部１４１を回転式電子部品部４５の各挿通孔５１と支持台６０の各挿通孔部６３に挿入し、支持台６０の下面側に露出する各取付固定部１４１の先端を熱かしめして取り付ける。 Next, the rotary electronic component part 45 of the flexible circuit board 20 is arranged on the lower surface of the case 120, and the support base 60 is installed on the lower side thereof. At this time, each mounting fixing part 141 of the case 120 is connected to the rotary electronic component part 45. Are inserted into each insertion hole 51 and each insertion hole 63 of the support base 60, and the tip of each attachment fixing part 141 exposed on the lower surface side of the support base 60 is attached by heat caulking.

そして第１，第２基板部２１，２３を重ね合せた押釦スイッチ部２５を、支持台６０の下面側に配置し、その下側に取付板１０を配置し、その際ケース１２０の各固定部１３７を押釦スイッチ部２５の各挿通部４３と取付板１０の各取付部１１とに挿入し、取付板１０の下面から露出する各固定部１３７の先端を熱かしめして取り付ける。これによって回転式電子部品１の組立が完了する。なお上記組立手順は一例であり、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。 And the pushbutton switch part 25 which overlap | superposed the 1st, 2nd board | substrate parts 21 and 23 is arrange | positioned at the lower surface side of the support stand 60, the mounting plate 10 is arrange | positioned under it, and each fixing | fixed part of case 120 in that case 137 is inserted into each insertion portion 43 of the push button switch portion 25 and each attachment portion 11 of the attachment plate 10, and the tip of each fixing portion 137 exposed from the lower surface of the attachment plate 10 is attached by heat caulking. Thereby, the assembly of the rotary electronic component 1 is completed. Note that the above assembling procedure is an example, and it goes without saying that the assembly may be performed using other various assembling procedures.

以上のように構成された回転式電子部品１において、回転つまみ２００を回転すると、これと一体に軸部材１５０、回転体７０、摺動子８０、補強板１００が回転し、摺動子８０の各弾接部８７が回転式電子部品部４５の摺接パターン４９上を摺動し、その電気的出力が変化する。そして回転つまみ２００を回転した際、グリス充填部１３５に充填されたグリス２２０内を軸部材１５０の抵抗付与部１５９が移動することでグリス２２０によるねっとり感のある回転抵抗（グリス抵抗）が生じる。即ちグリス抵抗はグリス充填部１３５に充填されたグリス２２０内にグリス充填部１３５の上方から抵抗付与部１５９を挿入することによって付与されるので、単に回転つまみ２００の回転軸とその軸受の間にグリスを塗布する場合に比べて、十分なグリス２２０によってグリス抵抗を付与でき、従来に比べてさらに十分なねっとり感が得られるばかりか、大きな抵抗が得られる。同時に補強板１００上をグリスを塗布した弾接バネ１１０の弾接部１１７が弾接して移動することで弾接バネ１１０による回転抵抗（弾接抵抗）が生じる。この回転式電子部品１においては、グリス抵抗の強さと弾接抵抗の強さとを略５０％ずつとしている。 In the rotary electronic component 1 configured as described above, when the rotary knob 200 is rotated, the shaft member 150, the rotating body 70, the slider 80, and the reinforcing plate 100 are rotated integrally therewith. Each elastic contact portion 87 slides on the sliding contact pattern 49 of the rotary electronic component portion 45, and its electrical output changes. When the rotary knob 200 is rotated, the resistance imparting portion 159 of the shaft member 150 moves in the grease 220 filled in the grease filling portion 135, so that a rotational resistance (grease resistance) with a feeling of stickiness due to the grease 220 is generated. That is, since the grease resistance is applied by inserting the resistance applying portion 159 from above the grease filling portion 135 into the grease 220 filled in the grease filling portion 135, the grease resistance is simply provided between the rotary shaft of the rotary knob 200 and its bearing. Compared to the case of applying grease, the grease resistance can be imparted by sufficient grease 220, and not only a more dull feeling can be obtained compared to the conventional case, but also a large resistance can be obtained. At the same time, the elastic contact portion 117 of the elastic contact spring 110 to which grease is applied moves elastically on the reinforcing plate 100, thereby causing rotational resistance (elastic contact resistance) by the elastic contact spring 110. In the rotary electronic component 1, the strength of the grease resistance and the strength of the elastic contact resistance are set to approximately 50% each.

つまりグリス抵抗と弾接抵抗の両者によって回転つまみ２００の回転に粘り（ねっとり感）があり且つ強い抵抗を付与できるが、その際、温度によって変化しない弾接抵抗によって、温度によって変化するグリス抵抗の変化を相対的に小さくすることができる。そして本回転式電子部品１によれば、上述のように従来に比べて十分なねっとり感が得られるので、例え弾接抵抗によってグリス抵抗が相対的に小さくなってもねっとり感としては十分なものが得られ、同時に温度によってねっとり感に変化は出るものの弾接抵抗があるので回転抵抗全体としては大きく変化することがなく、従って両回転抵抗（グリス抵抗と弾接抵抗）のバランスを図ることで、回転つまみ２００の回転時に適度な強さのねっとりとした粘りのある抵抗が得られると共にその抵抗が温度による影響を受け難い回転式電子部品１が得られる。 That is, both the grease resistance and the elastic contact resistance are sticky (sticky) to the rotation of the rotary knob 200 and can provide a strong resistance, but at this time, the elastic resistance that does not change with temperature causes the grease resistance that changes with temperature to change. The change can be made relatively small. According to this rotary electronic component 1, as described above, a sufficient feeling of stickiness can be obtained as compared with the prior art. Therefore, even if the grease resistance becomes relatively small due to the ball contact resistance, the feeling of stickiness is sufficient. At the same time, although there is a change in the feeling of stickiness depending on the temperature, there is an elastic contact resistance, so there is no significant change in the overall rotational resistance, so by balancing both rotational resistances (grease resistance and elastic contact resistance) Thus, a sticky resistance having a moderate strength can be obtained when the rotary knob 200 is rotated, and the rotary electronic component 1 is obtained in which the resistance is hardly affected by temperature.

特にこの回転式電子部品１においては、抵抗付与部１５９を構成する複数の円弧状板部材によってグリス充填部１３５内に充填したグリス２２０が攪拌されるので、隣り合う円弧状板部材間の隙間に充填されているグリス２２０が掻き回され、グリス２２０の粘性を効率的に十分に回転つまみ２００に伝達でき、ねっとりとした強い抵抗を付与できる。 In particular, in the rotary electronic component 1, the grease 220 filled in the grease filling portion 135 is agitated by a plurality of arc-shaped plate members constituting the resistance applying portion 159, so that the gap between adjacent arc-shaped plate members is stirred. The filled grease 220 is stirred, and the viscosity of the grease 220 can be efficiently and sufficiently transmitted to the rotary knob 200, so that a strong and strong resistance can be imparted.

またこの回転式電子部品１においては、グリスを軸部材１５０（その軸部材本体１５１の外周面）とケース１２０の軸受突部１３１（軸受孔１２９の内周面）の間にも塗布しているので、さらにグリスによるねっとりとした強い抵抗を得ることができる。 In the rotary electronic component 1, grease is also applied between the shaft member 150 (the outer peripheral surface of the shaft member main body 151) and the bearing protrusion 131 (the inner peripheral surface of the bearing hole 129) of the case 120. Therefore, it is possible to obtain a strong and strong resistance due to grease.

またこの回転式電子部品１においては、ケース１２０の回転つまみ２００側にグリス充填部１３５を設置し、ケース１２０の収納部１２７内の回転体７０よりも回転つまみ２００側に弾接バネ１１０を設置すると共に回転体７０の反対面側に電気的機能部である摺動子８０等を設置したので、グリス充填部１３５から十分離れた位置に電気的機能部を設置でき、グリス２２０が電気的機能部に達することを容易に防止できる。 In the rotary electronic component 1, the grease filling unit 135 is installed on the rotary knob 200 side of the case 120, and the elastic spring 110 is installed on the rotary knob 200 side of the rotary body 70 in the storage unit 127 of the case 120. In addition, since the slider 80 or the like, which is an electrical function unit, is installed on the opposite surface side of the rotating body 70, the electrical function unit can be installed at a position sufficiently away from the grease filling unit 135, and the grease 220 has an electrical function. It can be easily prevented from reaching the part.

一方押釦つまみ１８０のつまみ部１８１を押圧してこれを下降すれば、その押圧部１８５が押圧スイッチ３７上に設置した反転板４１を押圧してこれを反転し、押圧スイッチ３７がオンする。前記押圧を解除すれば反転板４１の弾性復帰力によって押釦つまみ１８０は元の位置に押し上げられ、押圧スイッチ３７はオフする。 On the other hand, when the knob portion 181 of the push button knob 180 is pressed and lowered, the pressing portion 185 presses the reversing plate 41 installed on the pressing switch 37 to reverse it, and the pressing switch 37 is turned on. When the pressing is released, the push button knob 180 is pushed up to the original position by the elastic restoring force of the reversing plate 41, and the pressing switch 37 is turned off.

なおこの回転式電子部品１においては、他部品収納部となる挿通部１５５及びつまみ部収納部１６７に、押釦つまみ１８０を回転つまみ２００の回転中心軸Ｌ方向に向かって移動可能に収納すると共に、押釦つまみ１８０の他部品収納部から露出する押圧部１８５によって押圧される位置に押圧スイッチ３７を配置したので押圧式電子部品付の回転式電子部品１を容易に構成できる。 In the rotary electronic component 1, the push button knob 180 is movably accommodated in the direction of the rotation center axis L of the rotary knob 200 in the insertion portion 155 and the knob portion storage portion 167 which are other component storage portions. Since the pressing switch 37 is disposed at a position pressed by the pressing portion 185 exposed from the other component storage portion of the push button knob 180, the rotary electronic component 1 with the pressing electronic component can be easily configured.

またこの回転式電子部品１においては、回転つまみ２００の軸部材収納部２０７内に囲み突部１３３まで含めて収納するので、グリス抵抗付与のための機構によって回転式電子部品１が大型化することもない。言い換えれば回転つまみ２００内の空きスペースを用いてグリス抵抗付与機構を設置している。 In addition, since the rotary electronic component 1 is housed in the shaft member storage portion 207 of the rotary knob 200 including the surrounding protrusion 133, the rotary electronic component 1 is increased in size by a mechanism for imparting grease resistance. Nor. In other words, the grease resistance applying mechanism is installed using an empty space in the rotary knob 200.

なお上記回転式電子部品１においては、ケース１２０（又はケース１２０に取り付けられるケース１２０側の他の部材でもよい）に弾接バネ１１０を取り付けることで、弾接バネ１１０を回転体７０（又は回転体７０と一体に回転する回転体７０側の他の部材、例えば補強板１００）に弾接させる構造としたが、その代りに弾接バネ１１０を回転体７０（又は回転体７０と一体に回転する回転体７０側の他の部材）に取り付けることで、弾接バネ１１０をケース１２０（又はケース１２０に取り付けられるケース１２０側の他の部材でもよい）に弾接させる構造としても良い。 In the rotary electronic component 1, the elastic contact spring 110 is attached to the case 120 (or another member on the case 120 side attached to the case 120), whereby the elastic contact spring 110 is rotated by the rotating body 70 (or rotating). The elastic member 110 is elastically contacted with another member on the side of the rotating body 70 that rotates integrally with the body 70, for example, the reinforcing plate 100. Instead, the elastic contact spring 110 rotates integrally with the rotating body 70 (or the rotating body 70). The elastic contact spring 110 may be elastically contacted to the case 120 (or another member on the case 120 side attached to the case 120) by being attached to the other member on the rotating body 70 side.
