Description

本発明は、回転式スイッチや回転式可変抵抗器等の各種回転式電子部品に用いて好適な回転式電子部品用摺動子に関するものである。 TECHNICAL FIELD The present invention relates to a slider for rotary electronic parts suitable for use in various rotary electronic parts such as rotary switches and rotary variable resistors.

従来、回転式電子部品に用いる摺動子の中には、例えば特許文献１の図３，図４に示す摺動子（８０）のように、基部（８１），（８３）の外周から突出するアーム部（８５）の根元部分を折り曲げ、折り曲げたアーム部（８５）の先端に接点部（８９）を設ける構造のものがあった。そして摺動子（８０）は、基部（８１），（８３）に設けた小孔からなる取付部（８７）に、回転体（５０）の下面に設けた小突起（６５）を挿入し、小突起（６５）の先端を熱カシメすることによって、回転体（５０）の下面に取り付けられる。 Conventionally, among the sliders used for rotary electronic parts, for example, like the slider (80) shown in FIGS. There has been a structure in which the root portion of the arm portion (85) to be connected is bent, and the contact portion (89) is provided at the tip of the bent arm portion (85). The slider (80) inserts a small protrusion (65) provided on the lower surface of the rotating body (50) into a mounting portion (87) consisting of small holes provided in the bases (81) and (83), By thermally crimping the tip of the small protrusion (65), it is attached to the lower surface of the rotating body (50).

しかし、上記構造の摺動子（８０）においては、小突起（６５）による熱カシメの箇所が破損した場合、アーム部（８５）の折り曲げた根元部分を支点にしてその基部（８１），（８３）が回転体（５０）の下面から離れる方向に移動しようとするため、接点部（８９）が摺接パターン（３１）に弾接する力が弱まって接触不良を起こしてしまう虞があった。 However, in the slider (80) having the structure described above, if the portion of the thermal crimping by the small projection (65) is damaged, the base (81), (81), (81), (81), (81), (81) and (81) of the bent arm portion (85) become the fulcrum. 83) tends to move away from the lower surface of the rotating body (50), the force with which the contact portion (89) makes elastic contact with the sliding contact pattern (31) weakens, possibly resulting in poor contact.

一方、回転式電子部品に用いる摺動子の中には、例えば特許文献２の図４に示す摺動子（１４０）のように、基部（１４１）の外周から突出する接点用アーム部（１４３）の根元部分を約１８０°折り返し、折り返して基部（１４１）上に位置する接点用アーム部（１４３）の先端に接点部（１４５）を設けた構造のものもあった。そしてこの摺動子（１４０）は、基部（１４１）に設けた取付孔（１４７）に、回転つまみ（１００）の摺動子取付面（１１３）に設けた取付突起（１２１）を挿入し、取付突起（１２１）の先端を熱カシメすることによって、回転つまみ（１００）の摺動子取付面（１１３）に取り付けられる。この摺動子（１４０）の場合、その構造上、接点部（１４５）が摺接パターン（１５７）に弾接することで、基部（１４１）の面全体が摺動子取付面（１１３）に押し付けられるので、取付突起（１２１）による熱カシメの箇所が破損しても、基部（１４１）は摺動子取付面（１１３）から浮き上がらず、このため接点部（１４５）の摺接パターン（１５７）との接触不良は生じにくい。 On the other hand, among the sliders used for rotary electronic parts, for example, like the slider (140) shown in FIG. ) is folded back about 180 degrees, and the contact point (145) is provided at the tip of the contact arm (143) located on the base (141). And this slider (140) inserts the mounting protrusion (121) provided on the slider mounting surface (113) of the rotary knob (100) into the mounting hole (147) provided in the base (141), It is attached to the slider mounting surface (113) of the rotary knob (100) by thermally crimping the tip of the mounting projection (121). In the case of this slider (140), due to its structure, the contact portion (145) is in elastic contact with the sliding contact pattern (157), so that the entire surface of the base (141) is pressed against the slider mounting surface (113). Therefore, even if the heat crimping portion of the mounting projection (121) is damaged, the base (141) does not rise from the slider mounting surface (113), and the sliding contact pattern (157) of the contact portion (145) does not rise. Poor contact with is unlikely to occur.

しかし、特許文献２に示す摺動子（１４０）の場合、接点用アーム部（１４３）が直線状であって且つ片持ち構造なので、この摺動子（１４０）を回転しながらその接点部（１４５）を摺接パターン（１５７）に摺接させた際、接点用アーム部（１４３）にねじれ方向のストレスが加わり、経年変化によって、接点用アーム部（１４３）が破断してしまう虞があった。また接点用アーム部（１４３）が片持ち構造なので、接点用アーム部（１４３）の長さが短くなり、その分、接点部（１４５）の摺接パターン（１５７）に対する接触圧が強くなり、摺接パターン（１５７）の寿命を短くしてしまう虞もあった。またこの摺動子（１４０）の接点用アーム部（１４３）は直線状なので、この接点用アーム部（１４３）を回転方向の接線方向に向けて設置してこれを回転した際に、その回転中心から最も離れた点（外側の接点用アーム部（１４３）の左右両角部）と、最も接近した点（内側の接点用アーム部（１４３）の内側辺中央部分）による軌跡の幅が、両接点用アーム（１４３）の直線方向の幅よりも大きくなり、その分、摺動子（１４０）の使用半径スペースを大きく取らなければならないという問題もあった。 However, in the case of the slider (140) shown in Patent Document 2, the contact arm (143) is linear and has a cantilever structure. 145) is brought into sliding contact with the sliding contact pattern (157), stress in the torsional direction is applied to the contact arm portion (143), and there is a risk that the contact arm portion (143) may break due to aging. rice field. Further, since the contact arm portion (143) has a cantilever structure, the length of the contact arm portion (143) is shortened, and the contact pressure of the contact portion (145) against the sliding contact pattern (157) is increased accordingly. There is also a risk of shortening the life of the sliding contact pattern (157). In addition, since the contact arm portion (143) of the slider (140) is linear, when the contact arm portion (143) is installed in the tangential direction of the rotation direction and rotated, the rotation The width of the trajectory from the point farthest from the center (right and left corners of the outer contact arm portion (143)) and the closest point (center portion of the inner side of the inner contact arm portion (143)) There is also the problem that the contact arm (143) has a larger width in the linear direction, and that the use radius space of the slider (140) must be increased accordingly.

The electronic component slider has a base attached to the slider mounting surface of the rotating body, a substantially linear portion is provided around the outer periphery of the base, and the base is positioned at the center of the substantially linear portion. When attached to the slider mounting surface of the rotating body, a concave portion is formed to avoid contact with the light guiding projection provided on the slider mounting surface, while the substantially straight line of the outer periphery of the base portion is formed.

The contact feeling can be improved, and the contact stability can be improved (reliable contact with the sliding contact pattern) by bringing the divided contact portions into sliding contact with the sliding contact pattern. A plurality of slits may be provided for one arm portion.

これによって、熱カシメ等による回転体への基部の固定が破損（完全な破損や、固定にゆるみが生じる等のがたつきの発生等を含む）した状態で、回転体を左右何れの方向に回転しても、左右回転方向の力は、一対の回転止め部によって支えられ、正常な動作を維持することができる。 The present invention also provides a rotary electronic component slider that is attached to a rotating body and that slides on a sliding contact pattern provided opposite to the rotating body to change its output signal, wherein the rotating body It has a base portion attached to the slider mounting surface, and an arm portion having both ends connected to two locations on the outer periphery of the base portion and having a contact portion formed in the middle of the arm portion that abuts on the sliding contact pattern. , the arm portion is positioned on the base portion by folding back portions near both ends of the arm portion from the base portion, and the arm portion has a contact portion divided from the vicinity of one folded portion to reach the vicinity of the other folded portion 1.

このとき、図６，図７に示すように、回転つまみ１００の操作部１０１の一部は、開口３０５から露出する。また第４ケース３００の照光部３０７の裏面に対向する位置に、導光体１９０の光出射面１９７が配置される。またこのとき、パッキン２５０は、第４ケース３００のパッキン搭載面３１１と、前記第１，第２ケース２０、７０のパッキン搭載面３３（３３ａ～３３ｃ），８１との間で挟持され、密閉される。 At this time, as shown in FIGS. 6 and 7, a portion of the operation portion 101 of the rotary knob 100 is exposed through the opening 305. FIG. A light exit surface 197 of the light guide 190 is arranged at a position facing the back surface of the illumination section 307 of the fourth case 300 . At this time, the packing 250 is sandwiched and sealed between the packing mounting surface 311 of the fourth case 300 and the packing mounting surfaces 33 (33a to 33c), 81 of the first and second cases 20, 70. be.

以上のようにして組み立てられた回転式電子部品１において、回転つまみ１００を回転すると、摺動子１０の接点部１７，１８が回路基板１６０の摺接パターン１６５上を摺動し、これによって各端子１４１間の検出出力が変化する。 In the rotary electronic component 1 assembled as described above, when the rotary knob 100 is rotated, the contact portions 17 and 18 of the slider 10 slide on the sliding contact pattern 165 of the circuit board 160, thereby The detection output between terminals 141 changes.

ここでこの実施形態に用いている摺動子１０においては、アーム部１３，１５の両端を基部１１の外周（外周辺１１ａ）の２か所に接続したので（両持ち構造）、アーム部１３，１５の基部１１への取付強度を強くすることができ、これによってアーム部１３，１５の破損を効果的に防止することができ、耐久性が向上する。またアーム部１３，１５は、摺動子１０の回転方向に沿う円弧形状なので、その接点部１７，１８を摺接パターン１６５に当接させながら回転した際でも、アーム部１３，１５がねじれることはなく、この点からも摺動子１０の耐久性を向上することができる。またこの摺動子１０のアーム部１３，１５は、摺動子１０の回転方向に沿う円弧状なので、これを回転した際の、その回転中心から最も離れた点（外側の円弧部分）と、最も接近した点（内側の円弧部分）による軌跡の幅が、両アーム部１３，１５の幅と同一になり、これによって、これらが直線状である場合に比べ、摺動子１０の使用半径スペースを小さくすることができる。 Here, in the slider 10 used in this embodiment, both ends of the arm portions 13 and 15 are connected to two points on the outer periphery (outer periphery 11a) of the base portion 11 (double-supported structure). , 15 to the base portion 11, thereby effectively preventing breakage of the arm portions 13, 15 and improving durability. Further, since the arm portions 13 and 15 are arc-shaped along the rotational direction of the slider 10, even when the contact portions 17 and 18 are rotated while being brought into contact with the sliding contact pattern 165, the arm portions 13 and 15 are not twisted. The durability of the slider 10 can be improved also from this point. In addition, since the arm portions 13 and 15 of the slider 10 are arcuate along the rotation direction of the slider 10, when the slider 10 is rotated, the point farthest from the center of rotation (outer arc portion), The width of the trajectory due to the point of closest approach (the inner arc portion) is the same as the width of both arms 13, 15, which makes the use radial space of the slider 10 smaller than if they were straight. can be made smaller.

同時に、アーム部１３，１５の両端近傍部分を基部１１から折り返すことでアーム部１３，１５を基部１１上（上方）に位置させたので、アーム部１３，１５の弾発力は、基部１１全体をほぼ均一に回転つまみ１００の摺動子取付面１１３に押え付ける方向の力として作用し、このため摺動子取付突部１１９の熱カシメ（又は圧入）等による基部１１の回転つまみ１００への固定が破損（完全な破損や、固定にゆるみが生じる等のがたつきの発生等を含む）しても、基部１１は浮き上がらず、このため接点部１７，１８の摺接パターン１６５への接触不良は生じにくく、回転式電子部品１としての機能を維持できる。特にこの摺動子１０の場合、基部１１に設けた位置決め部１１ｄに、摺動子取付面１１３に設けた位置決め部１２０を挿入しているので、摺動子取付突部１１９による固定が破損しても、摺動子１０の位置を、正規の位置に保持することができる。さらに、基部１１に設けた一対の回転止め部１１ｃが、摺動子取付面１１３に設けた回転止め部１２２に係止しているので、摺動子取付突部１１９による固定が破損した状態で、回転つまみ１００を左右何れの方向に回転しても、左右回転方向の力は、一対の回転止め部１２２によって支えられる。つまり、摺動子１０は、摺動子取付突部１１９による固定が破損しても、その機能を失うことなく、正常な動作を維持できる。 At the same time, the portions near both ends of the arm portions 13 and 15 are folded back from the base portion 11 to position the arm portions 13 and 15 on the base portion 11 (above). acts almost uniformly as a force in the direction of pressing against the slider mounting surface 113 of the rotary knob 100, so that the base portion 11 is pressed against the rotary knob 100 by thermal caulking (or press fitting) of the slider mounting projection 119 or the like. Even if the fixation is broken (including complete breakage and rattling caused by loosening of the fixation), the base portion 11 does not rise, and therefore the contact portions 17 and 18 do not contact the sliding contact pattern 165 properly. is unlikely to occur, and the function of the rotary electronic component 1 can be maintained. Particularly in the case of this slider 10, since the positioning portion 120 provided on the slider mounting surface 113 is inserted into the positioning portion 11d provided on the base portion 11, the fixing by the slider mounting protrusion 119 is damaged. However, the position of the slider 10 can be held at the regular position. Furthermore, since the pair of rotation stop portions 11c provided on the base portion 11 are engaged with the rotation stop portions 122 provided on the slider mounting surface 113, the fixing by the slider mounting protrusions 119 is damaged. , the force in the left-right direction is supported by the pair of rotation stoppers 122 even if the rotary knob 100 is rotated in either direction. In other words, the slider 10 can maintain normal operation without losing its function even if the fixing by the slider mounting projection 119 is damaged.

また上記摺動子１０においては、アーム部１３，１５が両持ち構造なので、片持ち構造に比べてアーム部１３，１５の長さを長くでき、その分、接点部１７，１８の摺接パターン１６５に対する接触圧を弱くでき、摺接パターン１６５の寿命を長くすることができる。さらに各アーム部１３，１５には、一方の折り返し部１３ａ，１５ａ近傍から接点部１７，１８を分割して他方の折り返し部１３ａ，１５ａ近傍に至るスリット１３ｃ，１５ｃを形成しているので、分割されたそれぞれの接点部１７，１８の摺接パターン１６５に対する接触圧をさらに小さくでき、さらに摺接パターン１６５の寿命を長くすることができると共に、その接触フィーリングを向上でき、さらに分割されたそれぞれの接点部１７，１８の内の少なくとも何れかが摺接パターン１６５に確実に摺接することで、接触安定性を向上することができる。 Further, in the slider 10, since the arms 13 and 15 are supported on both sides, the length of the arms 13 and 15 can be increased compared to the cantilever structure, and the sliding contact pattern of the contact points 17 and 18 is correspondingly increased. The contact pressure on 165 can be weakened, and the life of sliding contact pattern 165 can be lengthened. Further, in each arm portion 13, 15, slits 13c, 15c are formed from the vicinity of one of the folded portions 13a, 15a to divide the contact portions 17, 18 and extend to the vicinity of the other folded portion 13a, 15a. The contact pressure of the contact portions 17 and 18 with respect to the sliding contact pattern 165 can be further reduced, the life of the sliding contact pattern 165 can be extended, and the contact feeling can be improved. Contact stability can be improved by ensuring that at least one of the contact portions 17 and 18 is in sliding contact with the sliding contact pattern 165 .

また上記摺動子１０においては、その折り返し部１３ａ，１５ａとアーム部１３，１５と接点部１７，１８を、回転つまみ１００の摺動子取付面１１３の回転中心線に直交する仮想仕切り線Ｌ１（図１，図２参照）によって二分割される片側の領域内に収まるように構成しているので、少なくとも一対の摺動子１０をコンパクトに回転つまみ１００の摺動子取付面１１３に設置することができる。 In the slider 10, the folded portions 13a and 15a, the arm portions 13 and 15, and the contact portions 17 and 18 are arranged along an imaginary partition line L1 perpendicular to the rotation center line of the slider mounting surface 113 of the rotary knob 100. (See FIGS. 1 and 2) so that at least a pair of sliders 10 can be compactly installed on the slider mounting surface 113 of the rotary knob 100. be able to.

一方、発光素子１６９を発光すれば、その光は図８に一点鎖線で示すように、導光体１９０内に導入される。導光体１９０内に導入された光の一部は、光反射面１９９で反射されることで前記光出射面１９７に向かい、その面から放出され、前記第４ケース３００の照光部３０７をその裏面側から明るく照らし出す。一方、発光素子１６９から導光体１９０内に導入された光の一部は、光反射面１９９で反射されることで、前記光出射面１９５に向かい、その面から放出され、回転つまみ１００の光入射面１１７からつまみ用導光部Ａ１内に導入される。つまみ用導光部Ａ１内に導入された光は、導光軸部Ａ１３内を進み、光反射面１１０等で反射されることで、導光本体部Ａ１１内を進み、操作部１０１の外周面に導かれ、操作部１０１を明るく照らし出す。 On the other hand, when the light emitting element 169 emits light, the light is introduced into the light guide 190 as indicated by the dashed line in FIG. Part of the light introduced into the light guide 190 is reflected by the light reflecting surface 199 toward the light emitting surface 197, emitted from the surface, and directed to the illumination section 307 of the fourth case 300. Light up from the back side. On the other hand, part of the light introduced into the light guide body 190 from the light emitting element 169 is reflected by the light reflecting surface 199 toward the light emitting surface 195 and emitted therefrom. The light is introduced from the light incident surface 117 into the knob light guide portion A1. Light introduced into the knob light guide portion A1 travels through the light guide shaft portion A13, is reflected by the light reflecting surface 110 and the like, travels through the light guide body portion A11, and travels through the outer peripheral surface of the operation portion 101. and illuminates the operation unit 101 brightly.

一方、この回転式電子部品１は、図示しない電子機器の操作パネルに装着され、その際、第４ケース３００の化粧面３０３が、操作パネルの外部に露出する。そしてこの操作パネルの外部に露出した化粧面３０３に液体が降りかかることがある。降りかかった液体は、第４ケース３００の開口３０５からその内部に浸入する。浸入した液体は、第４ケース３００の内側面と、第１，第２ケース２０，７０の外側面との間の隙間から浸入しようとするが、その浸入は、パッキン２５０によって防止される。 On the other hand, this rotary electronic component 1 is attached to an operation panel of an electronic device (not shown), and at that time, the decorative surface 303 of the fourth case 300 is exposed to the outside of the operation panel. Liquid may splash on the decorative surface 303 exposed to the outside of the operation panel. The falling liquid enters the interior through the opening 305 of the fourth case 300 . The infiltrated liquid tries to enter through the gap between the inner surface of the fourth case 300 and the outer surfaces of the first and second cases 20 and 70, but the infiltration is prevented by the packing 250.
