Description

本発明は、回転式スイッチや回転式可変抵抗器等の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 such as a rotary switch or a rotary variable resistor.

従来、回転式電子部品は、例えば、抵抗体パターンやスイッチパターン等の摺接パターンを形成した回路基板をケースの収納凹部の底面に露出するように設置すると共に、前記収納凹部内に摺動子を取り付けた回転体を回転自在に収納し、さらにケースの収納部を塞ぐように取付板(カバー)を取り付けて構成されている。そして回転体を回転すれば、摺動子に設けた摺動接点が摺接パターン上を摺動し、これによって回転式電子部品の出力が変化する。   Conventionally, a rotary electronic component is, for example, installed such that a circuit board on which a sliding contact pattern such as a resistor pattern or a switch pattern is formed is exposed on the bottom surface of the housing recess, and the slider is placed in the housing recess. The rotating body to which is attached is rotatably stored, and a mounting plate (cover) is attached so as to close the housing portion of the case. When the rotating body is rotated, the sliding contact provided on the slider slides on the sliding contact pattern, thereby changing the output of the rotary electronic component.

ところで、摺接パターンは一般に複数本で構成される。例えば抵抗体パターンの場合は抵抗体パターンとコモンパターンの少なくとも2本、スイッチパターンの場合はオンオフパターンとコモンパターンの少なくとも2本が必要になる。このため前記複数本の摺接パターンは、1枚の回路基板上に同心円状に形成される。また分解能を向上させるため、外側の摺接パターンを抵抗体パターン又はスイッチパターン、内側のパターンをコモンパターンとする場合が多い。   Incidentally, the sliding contact pattern is generally composed of a plurality of pieces. For example, in the case of a resistor pattern, at least two of a resistor pattern and a common pattern are required, and in the case of a switch pattern, at least two of an on / off pattern and a common pattern are required. Therefore, the plurality of sliding contact patterns are formed concentrically on a single circuit board. Further, in order to improve the resolution, the outer sliding contact pattern is often a resistor pattern or a switch pattern, and the inner pattern is often a common pattern.

しかしながら、特許文献1(例えばその図2)にも示すように、内側の摺接パターンからその出力を回路基板の外周辺まで引き出す出力引出用パターンは、外側の摺接パターンの間を通さなければならないので、その分、外側の摺接パターンの長さが短くなり、外側の摺接パターンの有効角度が大きく取れないという問題があった。   However, as shown in Patent Document 1 (for example, FIG. 2), the output drawing pattern that draws the output from the inner sliding contact pattern to the outer periphery of the circuit board must pass between the outer sliding contact patterns. Therefore, there is a problem that the length of the outer sliding contact pattern is shortened correspondingly and the effective angle of the outer sliding contact pattern cannot be increased.

上記問題を解決して、外側の摺接パターンの有効角度を大きくとる方法としては、内側の摺接パターンの出力をスルーホールを用いて回路基板の反対面側に引き出す方法がある。しかしながらこのように構成すると、回路基板にスルーホール加工を施さなければならず、その製造が煩雑になってしまう。   As a method of solving the above problem and increasing the effective angle of the outer sliding contact pattern, there is a method of drawing the output of the inner sliding contact pattern to the opposite surface side of the circuit board using a through hole. However, if constituted in this way, the through hole processing must be performed on the circuit board, and the manufacture becomes complicated.

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、摺接パターンの有効角度を大きく取れ、同時に製造が容易に行える回転式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-described points, and an object of the present invention is to provide a rotary electronic component that can increase the effective angle of the sliding contact pattern and can be easily manufactured at the same time.

本発明によれば、第1,第2摺接パターンをそれぞれ第1,第2回路基板に形成したので、何れの摺接パターンも他方の摺接パターンによってその形成範囲が阻害されることはない。このため、何れの摺接パターンの有効角度も大きく取ることが可能になる。
また摺動子の第1,第2摺動接点を、回転体の回転中心軸から同一半径方向の上下に設けたので、第1摺動接点によって摺動子を押し下げようとする力と、第2摺動接点によって摺動子を押し上げようとする力が相殺される。このためこの摺動子及びこの摺動子を取り付けた回転体には、その回転中心軸を傾けようとする力は働かず、バランス良く回転させることができる。

Further, since the first and second sliding contacts of the slider are provided above and below in the same radial direction from the rotation center axis of the rotating body, the force to push down the slider by the first sliding contact, The force to push up the slider is canceled by the two sliding contacts. For this reason, a force to tilt the rotation center axis does not act on the slider and the rotating body to which the slider is attached, and the slider can be rotated with good balance.

The first output portion contact portion 101 is provided with a pair of small protrusion-like contact reinforcing contacts 107 bent in a convex shape so as to protrude upward. The first terminal contact portion 105 is configured by folding the tip of the arm portion 103 upward in a substantially arc shape.

図8は摺動子50を取り付けた回転体70の平面図、図9はその側面図、図10はその断面図、図11は摺動子50と回転体70を分離して示す斜視図である。なお、摺動子50は回転体70に一体成形されているので、本来は分解できないが、図11では説明の都合上、分離して示している。   8 is a plan view of the rotating body 70 to which the slider 50 is attached, FIG. 9 is a side view thereof, FIG. 10 is a sectional view thereof, and FIG. 11 is a perspective view showing the slider 50 and the rotating body 70 separately. is there. In addition, since the slider 50 is integrally formed with the rotating body 70, it cannot be disassembled originally, but is shown separately in FIG. 11 for convenience of explanation.

これらの図に示すように、摺動子50は弾性金属板をリング状に形成して構成されており、このリングの一部に第1,第2弾接用アーム51,53を設けてそれらの中間部分に第1,第2摺動接点55,57を形成すると共に、第1,第2弾接用アーム51,53の両端部(付け根部分)に回転体取付孔59を設けて構成されている。摺動子50の中央には、開口61が形成されている。第1弾接用アーム51は、中央の開口61を囲むように略弧状に形成され、また第2弾接用アーム53も開口61を囲み、且つ第1弾接用アーム51の外側を囲むように略弧状に形成されている。第1,第2弾接用アーム51,53は、その両端が回転体取付孔59を設けた部分に接続されている。また第1弾接用アーム51は、その両端部分が屈曲されることにより、斜め上方向に傾斜しており、その中央部分にはさらに上方向に突出するように上方向に屈曲してなる第1摺動接点55が形成されている。一方第2弾接用アーム53は、その両端部分が屈曲されることにより、斜め下方向に傾斜しており、その中央部分にはさらに下方向に突出するように下方向に屈曲してなる第2摺動接点57が形成されている。第1摺動接点55と第2摺動接点57を設ける位置は、図8,図9に示すように、摺動子50(即ち回転体70)の回転中心軸L1から同一半径方向D1(回転中心軸L1から直交して水平に進む方向)であり、且つ前記同一半径方向D1に向かってその上下に位置するように設けられている。なおこの摺動子50は、同一方向に向けて第1,第2弾接用アーム51,53を配置したので、開口61を中心にその両側に第1,第2弾接用アーム51,53を配置する場合に比べて、これを真上から見たときの専有面積を小さくでき、専有面積が小さい分、材料費を削減することができる。   As shown in these drawings, the slider 50 is formed by forming an elastic metal plate in a ring shape, and first and second elastic arms 51 and 53 are provided on a part of the ring, and these are provided. The first and second sliding contacts 55 and 57 are formed in the middle part of the first and second elastic contact arms 51 and 53, and the rotating body mounting holes 59 are provided at both ends (base portions). ing. An opening 61 is formed in the center of the slider 50. The first ball contact arm 51 is formed in a substantially arc shape so as to surround the central opening 61, and the second ball contact arm 53 also surrounds the opening 61 and surrounds the outside of the first ball contact arm 51. Are formed in a substantially arc shape. Both ends of the first and second elastic contact arms 51 and 53 are connected to a portion provided with a rotating body attachment hole 59. Further, the first elastic contact arm 51 is inclined obliquely upward by bending both end portions thereof, and the first elastic contact arm 51 is bent upward so that the central portion protrudes further upward. One sliding contact 55 is formed. On the other hand, the second elastic contact arm 53 is inclined downward by bending both end portions thereof, and the second elastic contact arm 53 is bent downward so as to protrude further downward at the central portion. Two sliding contacts 57 are formed. As shown in FIGS. 8 and 9, the first sliding contact 55 and the second sliding contact 57 are provided at the same radial direction D1 (rotation) from the rotation center axis L1 of the slider 50 (that is, the rotating body 70). In a direction that is perpendicular to the central axis L1 and travels horizontally), and is positioned so as to be positioned above and below the same radial direction D1. Since the slider 50 has the first and second elastic contacting arms 51 and 53 arranged in the same direction, the first and second elastic contacting arms 51 and 53 are arranged on both sides of the opening 61 as a center. Compared to the case of arranging the above, the exclusive area when viewed from directly above can be reduced, and the material cost can be reduced by the amount of the exclusive area.

回転体70は、前記摺動子50の中央に設けた開口61を通して成形されることで、その上下に、下記する第1回路基板30に設けた第1軸支孔33と、前記第2回路基板150に設けた第2軸支孔153にそれぞれ軸支させる第1,第2軸部71,73を設けると共に、前記摺動子50の一対の回転体取付孔59を通してその上下に形成される摺動子取付部75,75を設けて構成されている。第1軸部71は円筒状であって、下記する第1回路基板30の第1軸支孔33に回転自在に係合する寸法に形成され、第2軸部73も円筒状であって、前記第2回路基板150の第2軸支孔153に回転自在に係合する寸法に形成されている。摺動子取付部75は略矩形状であって摺動子50の上下に回転体取付孔59を介して一体に形成されている。両摺動子取付部75は、180°対向する位置に設けられている。回転体70の中央には、上下に貫通する貫通孔からなる駆動軸嵌合部77が形成されている。駆動軸嵌合部77は、図示しない操作つまみ等の駆動軸を嵌合して一体に回転自在となるように、非円形に形成されている。   The rotating body 70 is formed through an opening 61 provided in the center of the slider 50, so that a first shaft support hole 33 provided in the first circuit board 30 described below and the second circuit are formed above and below the rotary body 70. First and second shaft portions 71 and 73 that are respectively supported by second shaft support holes 153 provided in the substrate 150 are provided, and are formed above and below the pair of rotating body mounting holes 59 of the slider 50. The slider mounting portions 75 and 75 are provided. The first shaft portion 71 has a cylindrical shape and is dimensioned to be rotatably engaged with a first shaft support hole 33 of the first circuit board 30 described below, and the second shaft portion 73 is also cylindrical. The second circuit board 150 is formed to have a size that is rotatably engaged with the second shaft support hole 153 of the second circuit board 150. The slider attachment portion 75 has a substantially rectangular shape, and is integrally formed above and below the slider 50 via a rotating body attachment hole 59. Both slider attachment portions 75 are provided at positions facing each other by 180 °. In the center of the rotating body 70, a drive shaft fitting portion 77 formed of a through hole penetrating vertically is formed. The drive shaft fitting portion 77 is formed in a non-circular shape so that a drive shaft such as an operation knob (not shown) can be fitted and rotated integrally.

回転体70は、上述のように、摺動子50の中央に設けた開口61を通して成形するので、回転体70の外径寸法を摺動子50の外径寸法よりも小さく構成できる。同時に摺動子50の回転体取付孔59を通してその上下に回転体70の摺動子取付部75を設けるので、回転体70と摺動子50間の固定強度を強く保つことができる。   Since the rotating body 70 is formed through the opening 61 provided in the center of the slider 50 as described above, the outer diameter of the rotating body 70 can be configured smaller than the outer diameter of the slider 50. At the same time, the slider mounting portions 75 of the rotating body 70 are provided above and below the rotating body mounting hole 59 of the slider 50, so that the fixing strength between the rotating body 70 and the slider 50 can be kept strong.

第1回路基板30は、例えば0.4mm程度の厚みの板状硬質の合成樹脂板(例えばPPSやLCP等)からなる絶縁基板31の所定位置(中央)に円形の貫通する第1軸支孔33を例えば打ち抜き加工によって設け、またその下面の第1軸支孔33の周囲を囲む位置に、リング状で所定の幅を有する第1摺接パターン(以下「コモンパターン」という)35を形成して構成されている。コモンパターン35の外周には、引出パターン37が接続され、第1回路基板30の外周の一辺30aの中央付近に設けられた略矩形状の第1出力部(端子接続パターン)39に接続されている。第1回路基板30の外周近傍の所定位置には、前記ケース120に設けた位置決め部127に挿入される小孔からなるケース位置決め部41が設けられている。コモンパターン35と引出パターン37と第1出力部39は、何れもスクリーン印刷や拭き付け等の各種パターン形成方法によって形成されている。   The first circuit board 30 is a first shaft support hole that penetrates in a circular shape at a predetermined position (center) of the insulating substrate 31 made of a plate-like hard synthetic resin plate (for example, PPS or LCP) having a thickness of about 0.4 mm. 33 is formed by, for example, punching, and a first sliding contact pattern (hereinafter referred to as “common pattern”) 35 having a predetermined width is formed in a ring shape at a position surrounding the periphery of the first shaft support hole 33 on the lower surface thereof. Configured. A lead pattern 37 is connected to the outer periphery of the common pattern 35 and is connected to a substantially rectangular first output portion (terminal connection pattern) 39 provided near the center of one side 30 a of the outer periphery of the first circuit board 30. Yes. At a predetermined position in the vicinity of the outer periphery of the first circuit board 30, a case positioning part 41 made up of a small hole inserted into the positioning part 127 provided in the case 120 is provided. The common pattern 35, the drawing pattern 37, and the first output unit 39 are all formed by various pattern forming methods such as screen printing and wiping.

取付板10は金属板製であり、前記第1回路基板30及びケース120を覆うように略矩形状に形成されている。取付板10の中央には円形で、前記第1回路基板30の第1軸支孔33の内径寸法よりも大きい内径寸法の開口部11が形成されている。取付板10の外周の対向する二辺からは、2本ずつ舌片状の係止片13が突出し下方向を向くように折り曲げられている。また係止片13を設けない別の対向する二辺からは、1本ずつ舌片状の固定片15が突出している。固定片15は、下方向に約直角に折り曲げられた後、外方向(逆方向)に約直角に折り曲げられている。固定部15は、例えばこの回転式電子部品1−1を図示しない別の回路基板上に取り付ける際に、この別の回路基板に半田付けすることでその取付強度を強くする等のために用いる。   The mounting plate 10 is made of a metal plate, and is formed in a substantially rectangular shape so as to cover the first circuit board 30 and the case 120. In the center of the mounting plate 10, an opening 11 having a circular shape and an inner diameter dimension larger than the inner diameter dimension of the first shaft support hole 33 of the first circuit board 30 is formed. From the two opposite sides of the outer periphery of the mounting plate 10, two tongue-like locking pieces 13 protrude and are bent so as to face downward. In addition, a tongue-like fixing piece 15 protrudes one by one from two opposite sides where the locking piece 13 is not provided. The fixed piece 15 is bent at a right angle in the downward direction and then bent at a right angle in the outer direction (reverse direction). For example, when the rotating electronic component 1-1 is mounted on another circuit board (not shown), the fixing unit 15 is used to increase the mounting strength by soldering to the other circuit board.

回転式電子部品1−1を組み立てるには、まずケース120の収納部121内に回転体70を収納し、その際、回転体70の第2軸部73を第2回路基板150の第2軸支孔153とケース120の第2軸支孔123に回動自在に挿入する。このとき、摺動子50の第2摺動接点57が抵抗体パターン155に当接する。   In order to assemble the rotary electronic component 1-1, first, the rotating body 70 is stored in the storage portion 121 of the case 120, and at this time, the second shaft portion 73 of the rotating body 70 is connected to the second shaft of the second circuit board 150. It is rotatably inserted into the support hole 153 and the second shaft support hole 123 of the case 120. At this time, the second sliding contact 57 of the slider 50 contacts the resistor pattern 155.

次にケース120の導通部材収納部125内に板バネ100を収納する。このとき、板バネ100左右の第1端子部当接部105,105は、それぞれケース120の第1端子部163(その載置部163a)に当接する。   Next, the leaf spring 100 is housed in the conducting member housing portion 125 of the case 120. At this time, the first terminal contact portions 105 and 105 on the left and right of the leaf spring 100 are in contact with the first terminal portion 163 (the mounting portion 163a) of the case 120, respectively.

次にケース120の収納部121及び導通部材収納部125を覆うように、ケース120の上に第1回路基板30を載置する。このとき、ケース120の位置決め部127を第1回路基板30のケース位置決め部41に挿入し位置決めする。同時に回転体70の第1軸部71を第1回路基板30の第1軸支孔33に回転自在に挿入する。このとき、摺動子50の第1摺動接点55がコモンパターン35に当接し、且つ板バネ100の第1出力部当接部101が第1出力部39に当接する。そして第1回路基板30の上に取付板10を被せて、各係止片13をケース120の係止片収納凹部129に挿入し、各係止片13の先端をケース120の下面側に折り曲げれば、回転式電子部品1−1が完成する。このとき回転体70の第1軸部71は取付板10の開口部11内に挿入されている。以上説明したように、回転式電子部品1−1の組み立て(製造)は容易に行える。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 first circuit board 30 is placed on the case 120 so as to cover the storage part 121 and the conductive member storage part 125 of the case 120. At this time, the positioning portion 127 of the case 120 is inserted into the case positioning portion 41 of the first circuit board 30 for positioning. At the same time, the first shaft portion 71 of the rotating body 70 is rotatably inserted into the first shaft support hole 33 of the first circuit board 30. At this time, the first sliding contact 55 of the slider 50 contacts the common pattern 35, and the first output portion contact portion 101 of the leaf spring 100 contacts the first output portion 39. Then, the mounting plate 10 is placed on the first circuit board 30, the respective locking pieces 13 are inserted into the locking piece storage recesses 129 of the case 120, and the tips of the respective locking pieces 13 are bent to the lower surface side of the case 120. Then, the rotary electronic component 1-1 is completed. At this time, the first shaft portion 71 of the rotating body 70 is inserted into the opening 11 of the mounting plate 10. As described above, assembly (production) of the rotary electronic component 1-1 can be easily performed. 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回転式電子部品1−1において、回転体70を回転すると、これと一体に摺動子50が回転し、第1,第2摺動接点55,57がそれぞれ第1回路基板30のコモンパターン35上と第2回路基板150の抵抗体パターン155上を同時に摺動する。これによって抵抗体パターン155の両端に接続されている一対の第2端子部165と、第1回路基板30のコモンパターン35に第1出力部39と板バネ100を介して接続されている第1端子部163間の抵抗値が変化する。   In the rotary electronic component 1-1 assembled as described above, when the rotating body 70 is rotated, the slider 50 rotates integrally therewith, and the first and second sliding contacts 55 and 57 are respectively connected to the first and second sliding contacts 55 and 57. It slides on the common pattern 35 of the first circuit board 30 and the resistor pattern 155 of the second circuit board 150 simultaneously. As a result, the pair of second terminal portions 165 connected to both ends of the resistor pattern 155 and the first output portion 39 and the first spring 39 connected to the common pattern 35 of the first circuit board 30 via the leaf spring 100. The resistance value between the terminal portions 163 changes.

上記回転式電子部品1−1において、摺動子50の第1,第2摺動接点55,57は、それぞれ第1回路基板30のコモンパターン35と第2回路基板150の抵抗体パターン155に弾接するが、第1,第2摺動接点55,57が弾接する位置は、図3に示すように、回転体70の回転中心軸L1から同一半径方向D1なので、第1摺動接点55によって摺動子50を下降させようとする力と、第2摺動接点57によって摺動子50を上昇させようとする力(図3に示す回転体70及び摺動子50を紙面の面内で回転させようとするモーメント力)は相殺される。このため摺動子50及び回転体70には、その回転中心軸L1を傾けようとする力(偏心させようとする力)は働かず、バランス良く回転することができる。もし摺動子50及び回転体70に、その回転中心軸L1を傾けようとする力が働くと、回転体70の第1,第2軸部71,73が第1,第2軸支孔33,153,123に片当りし、片当りした部分が摩耗して商品寿命が短くなるばかりか、回転中心軸L1が偏心することで回転式電子部品1−1の出力の精度が低下してしまう(例えば抵抗値の変化が精度の良い直線ではなくなる等)。   In the rotary electronic component 1-1, the first and second sliding contacts 55 and 57 of the slider 50 are respectively connected to the common pattern 35 of the first circuit board 30 and the resistor pattern 155 of the second circuit board 150. The positions where the first and second sliding contacts 55 and 57 are in elastic contact are in the same radial direction D1 from the rotation center axis L1 of the rotating body 70 as shown in FIG. The force to lower the slider 50 and the force to raise the slider 50 by the second sliding contact 57 (the rotating body 70 and the slider 50 shown in FIG. The moment force to be rotated) is canceled out. For this reason, the slider 50 and the rotating body 70 do not receive a force for tilting the rotation center axis L1 (a force for decentering), and can rotate with good balance. If a force is applied to the slider 50 and the rotating body 70 to incline the rotation center axis L1, the first and second shaft portions 71 and 73 of the rotating body 70 are connected to the first and second shaft support holes 33. , 153, and 123, and the contacted part is worn and the product life is shortened, and the rotation center axis L1 is decentered, so that the output accuracy of the rotary electronic component 1-1 is lowered. (For example, the change in resistance value is no longer an accurate straight line).

また上記回転式電子部品1−1によれば、コモンパターン35と抵抗体パターン155をそれぞれ第1,第2回路基板30,150に形成したので、何れの摺接パターン35,155も他方の摺接パターン155,35によってその形成範囲が制限されることはない。このため、何れの摺接パターン35,155の有効角度も大きく取ることが可能になり、出力の分解能を向上させることができる。   Further, according to the rotary electronic component 1-1, since the common pattern 35 and the resistor pattern 155 are formed on the first and second circuit boards 30 and 150, respectively, any of the sliding contact patterns 35 and 155 is the other sliding pattern. The formation range is not limited by the contact patterns 155 and 35. For this reason, the effective angle of any of the sliding contact patterns 35 and 155 can be increased, and the output resolution can be improved.

また上記回転式電子部品1−1によれば、第1出力部39と第1端子部163に同時に弾接する構造の簡単な板バネ100によって、容易且つ確実に、第1回路基板30側の出力を、第2回路基板150側から取り出すことができる。板バネ100は、上述のように、中央の第1出力部当接部101の対向する両側部から一対のアーム部103を突出する構造なので、左右のバランスがとれている。このため板バネ100の圧縮された弾発力はそのままバランス良く、第1出力部当接部101の第1出力部39への弾接力、及び一対の第1端子部当接部105,105の第1端子部163,163への弾接力となり、無駄な力を失うことなく作用する。さらに第1出力部当接部101には当接補強用接点107が設けられているので、第1出力部39との電気的接続をより確実にすることができる。   Further, according to the rotary electronic component 1-1, the output on the first circuit board 30 side can be easily and reliably performed by the simple leaf spring 100 having a structure in which the first output portion 39 and the first terminal portion 163 are simultaneously elastically contacted. Can be taken out from the second circuit board 150 side. As described above, the leaf spring 100 has a structure in which the pair of arm portions 103 protrudes from opposite side portions of the central first output portion abutting portion 101, so that the left and right balance is achieved. For this reason, the compressed elastic force of the leaf spring 100 is balanced as it is, the elastic contact force of the first output part contact part 101 to the first output part 39, and the pair of first terminal part contact parts 105, 105. It becomes an elastic contact force to the first terminal portions 163 and 163 and acts without losing useless force. Further, the first output portion contact portion 101 is provided with the contact reinforcing contact 107, so that the electrical connection with the first output portion 39 can be made more reliable.

図12は本発明の他の実施形態に係る回転式電子部品1−2を示す断面図であり、図3と同一部分での断面を示している。同図に示す回転式電子部品1−2において、前記図1〜図11に示す回転式電子部品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11に示す実施形態と同じである。   12 is a cross-sectional view showing a rotary electronic component 1-2 according to another embodiment of the present invention, and shows a cross section of the same portion as FIG. In the rotary electronic component 1-2 shown in the figure, the same or corresponding parts as those of the rotary electronic component 1-1 shown in FIGS. 2 ”). Note that matters other than those described below are the same as those in the embodiment shown in FIGS.

この回転式電子部品1−2において、前記回転式電子部品1−1と相違する点は、回転式電子部品1−1で用いた第1回路基板30を、この回転式電子部品1−2の上部を覆う取付板10−2に兼用させた点と、回転式電子部品1−1で用いた板バネ100及び板バネ100に弾接する第1端子部163を省略した点である。そして、金属板製の取付板(第1回路基板でもある)10−2の下面に、前記回転式電子部品1−1の第1回路基板30に設けていたコモンパターン35−2を形成している。また上記回転式電子部品1−1の取付板10では固定片15とした部分を、この回転式電子部品1−2の取付板10−2では第1端子部17−2としている。つまりこの回転式電子部品1−2では、コモンパターン35−2側の出力を金属板である取付板10−2を介して第1端子部17−2に出力する構成となっている。このように構成しても、上記回転式電子部品1−1と同様の機能及び作用効果を生じる。   This rotary electronic component 1-2 is different from the rotary electronic component 1-1 in that the first circuit board 30 used in the rotary electronic component 1-1 is replaced by the rotary electronic component 1-2. This is a point that is also used as the mounting plate 10-2 that covers the upper part, and a point that the leaf spring 100 used in the rotary electronic component 1-1 and the first terminal portion 163 that elastically contacts the leaf spring 100 are omitted. Then, the common pattern 35-2 provided on the first circuit board 30 of the rotary electronic component 1-1 is formed on the lower surface of the metal plate mounting plate (which is also the first circuit board) 10-2. Yes. Moreover, the part made into the fixed piece 15 in the mounting plate 10 of the said rotary electronic component 1-1 is made into the 1st terminal part 17-2 in the mounting plate 10-2 of this rotary electronic component 1-2. That is, the rotary electronic component 1-2 is configured to output the output on the common pattern 35-2 side to the first terminal portion 17-2 via the mounting plate 10-2 that is a metal plate. Even if comprised in this way, the function and effect similar to the said rotary electronic component 1-1 will be produced.

金属板である取付板10−2にコモンパターン35−2を設けたのは、金属板の表面に直接摺動子50−2の第1摺動接点55−2を弾接・摺動させると、一般に金属板の表面はざらついているので、第1摺動接点55−2の摩耗が激しくなって耐久性の問題を生じたり、接触不良を生じたりする恐れがあるからである。従ってそのような恐れが無いような場合は、コモンパターン35−2の形成を省略して第1摺動接点55−2を直接取付板10−2の下面に摺接させても良い。   The common pattern 35-2 is provided on the mounting plate 10-2 which is a metal plate when the first sliding contact 55-2 of the slider 50-2 is elastically contacted and slid directly on the surface of the metal plate. In general, since the surface of the metal plate is rough, there is a possibility that the first sliding contact 55-2 may be heavily worn, resulting in a problem of durability or a contact failure. Therefore, when there is no such fear, the formation of the common pattern 35-2 may be omitted, and the first sliding contact 55-2 may be slid directly into the lower surface of the mounting plate 10-2.

この回転式電子部品1−2のように構成すれば、その部品点数を削減できると同時に組立工数も削減でき、さらなる製造コストの低廉化が図れ、同時に構造の簡素化と厚みの薄型化を図ることができる。   If the rotary electronic component 1-2 is configured, the number of components can be reduced and the number of assembling steps can be reduced, and the manufacturing cost can be further reduced. At the same time, the structure is simplified and the thickness is reduced. be able to.

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、上記した一対の第1端子部163,163と板バネ100は、これらを一体に形成しても良い。つまりアーム部105,105の先端に、直接第1端子部163,163を取り付けた構成としても良い。   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, the pair of first terminal portions 163 and 163 and the leaf spring 100 described above may be integrally formed. That is, the first terminal portions 163 and 163 may be directly attached to the tips of the arm portions 105 and 105.

上記例では、第1,第2回路基板として硬質基板を用いたが、これは硬質基板の代りに樹脂フイルム製のフレキシブル回路基板を用いる場合に比べて、耐熱性を向上させるためである(例えばこの回転式電子部品を他の回路基板に半田付けする際の半田リフロー時の耐熱性向上のため)。従って、耐熱性の条件が低いような場合等は、回路基板としてフレキシブル回路基板を用いても良い。また第1,第2摺接パターンは、抵抗体パターンとコモンパターンの組み合わせに限定されず、スイッチパターン等の他の各種機能や形状、構造を有する摺接パターンであっても良い。また上記例では第1,第2回路基板にそれぞれ1本ずつ摺接パターンを設けたが、何れか一方又は両者に形成する摺接パターンを複数本としても良い。   In the above example, a hard substrate is used as the first and second circuit boards, but this is to improve heat resistance as compared to the case where a flexible circuit board made of a resin film is used instead of the hard board (for example, (To improve heat resistance during solder reflow when soldering this rotary electronic component to another circuit board). Therefore, a flexible circuit board may be used as the circuit board when the heat resistance is low. Further, the first and second sliding contact patterns are not limited to the combination of the resistor pattern and the common pattern, and may be sliding contact patterns having other various functions, shapes, and structures such as a switch pattern. In the above example, one slidable contact pattern is provided on each of the first and second circuit boards, but a plurality of slidable contact patterns formed on either one or both may be provided.

また導通部材の形状、構造も種々の変更が可能であり、例えば、前記第1回路基板30の下面に形成した第1出力部39(図5参照)の左右の端部を、前記左右の載置部163a,165a(図4参照)に対向する位置まで左右に延ばし、これら左右に延ばした第1出力部39と左右の載置部163a,165aとの間に、それぞれコイルバネ等からなる導通部材を挟持・弾接させることで、第1出力部39と第1端子部163とを導通しても良い。要は、第1出力部と第1端子部に同時に当接して導通させる導通部材であればよい。   The shape and structure of the conducting member can be variously changed. For example, the left and right end portions of the first output portion 39 (see FIG. 5) formed on the lower surface of the first circuit board 30 are mounted on the left and right mounting portions. A conductive member that extends to the left and right to a position facing the mounting portions 163a and 165a (see FIG. 4), and is formed of a coil spring or the like between the first output portion 39 and the left and right mounting portions 163a and 165a. The first output unit 39 and the first terminal unit 163 may be electrically connected by sandwiching and elastically contacting each other. In short, any conductive member may be used as long as it is in contact with the first output unit and the first terminal unit at the same time.
