Description

本発明は、特に小型モータに係り、回転子のコイルに流れる電流を反転させるための整流子を有するモータに関するものである。   The present invention relates to a small motor, and more particularly to a motor having a commutator for reversing a current flowing in a rotor coil.

従来、このような分野の技術として、特開平９−１１７１０９号公報がある。この公報に記載された整流子は、金属の薄板からなる整流子片が樹脂製のスリーブに取り付けられた構成を有し、スリーブの鍔部から整流片のライザ部が突出している。また、スリーブの鍔部は、円形のものと特殊なＹ字状のものとがあり、何れの場合も、鍔部は、整流子片のライザ部の補強として機能している。   Conventionally, there is JP-A-9-117109 as a technique in such a field. The commutator described in this publication has a configuration in which a commutator piece made of a thin metal plate is attached to a resin sleeve, and a riser portion of the commutator piece protrudes from a flange portion of the sleeve. Moreover, the collar part of a sleeve has a circular thing and a special Y-shaped thing, and in any case, the collar part functions as reinforcement of the riser part of a commutator piece.

特開平９−１１７１０９号公報JP-A-9-117109 特開平１０−２７１７６９号公報Japanese Patent Laid-Open No. 10-271769

モータでは、トルクを出すためにコイルの巻数を多くする必要があるが、モータを小型化する場合、全長を短くしようとすると、鉄心と円形の鍔部との隙間寸法が小さくなる。その結果、コイルの巻数が少なくなり、これによって、モータトルクが小さくなってしまうといった問題点がある。これに対し、小型モータにおいて、コイルの巻数を多くしようとして、鍔部を特殊なＹ字形状にすると、鍔部の外形が特殊な形状になるので、電線を整流子片の切り込み部分に引っ掛け難くなり、その結果として、切り込み部分に対する電線の引っ掛かり精度が悪くなり、整流子片に電線を半田付けする際に接続不良が発生し易くなる虞がある。   In the motor, it is necessary to increase the number of turns of the coil in order to generate torque. However, when the motor is downsized, if the overall length is to be shortened, the gap dimension between the iron core and the circular flange portion is reduced. As a result, there is a problem that the number of turns of the coil is reduced, thereby reducing the motor torque. On the other hand, in a small motor, when trying to increase the number of turns of the coil and making the collar part into a special Y shape, the outer shape of the collar part becomes a special shape, so it is difficult to hook the electric wire on the cut portion of the commutator piece. As a result, the hooking accuracy of the electric wire with respect to the cut portion is deteriorated, and there is a possibility that poor connection is likely to occur when the electric wire is soldered to the commutator piece.

本発明は、特に、小型化を促進させる上で、トルクの増大を図りつつ整流子片に対する電線の引っ掛かりを良好にして、電線を整流子片に半田付けする際の半田不良をなくすようにしたモータを提供することを目的とする。   In particular, in order to promote downsizing, the present invention improves the hooking of the electric wire to the commutator piece while increasing the torque, and eliminates the defective soldering when the electric wire is soldered to the commutator piece. An object is to provide a motor.

本発明に係るモータは、シャフトに固定された鉄心に電線が巻かれたコイルを有する回転子と、シャフトに固定されると共に電線に電流を供給する整流子と、回転子を包囲するように配置されたマグネットとを有するモータにおいて、整流子は、シャフトに固定されると共に、円形の鍔部を有するスリーブと、スリーブの表面に沿って配置されるベース部と、円形の鍔部の外周面から突出するようにベース部の端部から起立するライザ部と、スリーブの鍔部の外周面に隣接してライザ部に設けられた電線引掛け用切り込み部とからなる整流子片とを有し、シャフトの軸線方向において、円形の鍔部には、コイルと対向する位置に凹部が設けられていることを特徴とする。   A motor according to the present invention includes a rotor having a coil in which an electric wire is wound around an iron core fixed to a shaft, a commutator that is fixed to the shaft and supplies current to the electric wire, and is arranged so as to surround the rotor. The commutator is fixed to the shaft and has a sleeve having a circular flange, a base portion disposed along the surface of the sleeve, and an outer peripheral surface of the circular flange. A riser portion that stands up from the end of the base portion so as to protrude, and a commutator piece that includes a wire hooking cutout portion provided in the riser portion adjacent to the outer peripheral surface of the flange portion of the sleeve, In the axial direction of the shaft, the circular flange is provided with a recess at a position facing the coil.

このモータにおいては、整流子片の電線引掛け用切り込み部に対する電線の引っ掛かりを良好にして、整流子片に電線を半田付けする際の不良発生を防止するために、円形の鍔部を有するスリーブが採用されている。このような円形の鍔部をもったスリーブにおいては、鉄心と円形の鍔部との隙間寸法が小さくなって、コイルの巻数が少なくなってしまうといった不具合があるので、シャフトの軸線方向において、円形の鍔部には、コイルと対向する位置に凹部が設けられている。これによって、モータの小型化を促進させる上で、所望のモータトルクを得ることができる。鍔部に凹部を形成することは、モータが小型化されればされる程、有効である。   In this motor, a sleeve having a circular flange is used to improve the hooking of the electric wire with respect to the wire hooking cut portion of the commutator piece and to prevent the occurrence of defects when the electric wire is soldered to the commutator piece. Is adopted. In such a sleeve having a circular flange, there is a problem that the gap dimension between the iron core and the circular flange is reduced and the number of turns of the coil is reduced. A concave portion is provided in the collar portion at a position facing the coil. As a result, a desired motor torque can be obtained in promoting the miniaturization of the motor. It is more effective to form the recess in the collar portion as the motor is made smaller.

また、隣接する整流子片のライザ部間において、凹部は、鍔部の外周から切り込まれるような形状を有すると好適である。このような構成は、鍔部の強度が最大限発揮される円形の鍔部を採用しつつ、スリーブの小型化を図る上で最適である。   Moreover, it is suitable that a recessed part has a shape cut | disconnected from the outer periphery of a collar part between the riser parts of an adjacent commutator piece. Such a configuration is optimal for reducing the size of the sleeve while adopting a circular collar that maximizes the strength of the collar.

本発明によれば、小型化を促進させる上で、トルクの増大を図りつつ整流子片に対する電線の引っ掛かりを良好にして、電線を整流子片に半田付けする際の半田不良をなくすことができる。   According to the present invention, in order to promote downsizing, it is possible to improve the hooking of the electric wire to the commutator piece while increasing the torque, and to eliminate the solder failure when the electric wire is soldered to the commutator piece. .

以下、図面を参照しつつ本発明に係るモータの好適な実施形態について詳細に説明する。   Hereinafter, preferred embodiments of a motor according to the present invention will be described in detail with reference to the drawings.

図１〜図３に示すように、モータ１は、コアードモータからなると共に、円筒状の金属製ハウジング２を有し、ハウジング２の後端部には、一対のブラシが組み付けられた樹脂製のブラケット（図示せず）が固定されている。このモータ１は、小型のモータに属するものであり、ハウジング２は、直径１０ｍｍ以下（例えば６〜３ｍｍ）で長さ約１ｃｍ程度の円筒形を有し、このような小さなハウジング２内に固定子３や回転子６が収容されている。   As shown in FIGS. 1 to 3, the motor 1 includes a cored motor and has a cylindrical metal housing 2, and a resin bracket with a pair of brushes assembled to the rear end of the housing 2. (Not shown) is fixed. The motor 1 belongs to a small motor, and the housing 2 has a cylindrical shape with a diameter of 10 mm or less (for example, 6 to 3 mm) and a length of about 1 cm. A stator is provided in the small housing 2. 3 and the rotor 6 are accommodated.

ハウジング２の内壁面２ａには、Ｎ，Ｓ極をもった永久磁石からなる固定子（マグネット）３が固定され、ハウジング２の内部には、三本の鉄心溝（スロット）をもった鉄心５のポール５ａに電線Ｗが巻かれたコイルＣを有する回転子６が収容されている。そして、回転子６の鉄心５は、厚さ０．２〜０．５ｍｍ程度の珪素鋼板を打ち抜き加工することにより作り出された薄板状のコア９をシャフト７の軸線方向に積層して構成され、積層コアとも呼ばれている。また、このような回転子６の中心にはシャフト７が固定され、シャフト７は、ハウジング２の前端を貫通するように延在すると共に、前後一対の軸受（図示せず）によって軸支されている。   A stator (magnet) 3 made of a permanent magnet having N and S poles is fixed to an inner wall surface 2 a of the housing 2, and an iron core 5 having three iron core grooves (slots) inside the housing 2. The rotor 6 having the coil C around which the electric wire W is wound is accommodated in the pole 5a. And the iron core 5 of the rotor 6 is configured by laminating a thin plate-like core 9 produced by punching a silicon steel plate having a thickness of about 0.2 to 0.5 mm in the axial direction of the shaft 7, It is also called a laminated core. Further, a shaft 7 is fixed to the center of the rotor 6, and the shaft 7 extends so as to penetrate the front end of the housing 2 and is supported by a pair of front and rear bearings (not shown). Yes.

更に、シャフト７の後端には、回転子６のコイルＣに流れる電流を反転させる整流子１０が固定され、この整流子１０にはブラシ（図示せず）が摺動接触し、このブラシと整流子１０との協働によってコイルＣへの適切な給電を図っている。また、シャフト７の先端には、略半円柱状の分銅（図示せず）が圧入され、シャフト７の回転力で分銅を高速に回転させることで、ハウジング２自体が振動する。このような分銅は、携帯用小型無線呼出器（例えば携帯電話等）で機器自体の筺体を振動させる場合に採用されている。   Further, a commutator 10 that reverses the current flowing through the coil C of the rotor 6 is fixed to the rear end of the shaft 7, and a brush (not shown) is in sliding contact with the commutator 10. Appropriate power supply to the coil C is achieved by cooperation with the commutator 10. Further, a weight (not shown) having a substantially semi-cylindrical shape is press-fitted into the tip of the shaft 7, and the housing 2 itself vibrates by rotating the weight at a high speed by the rotational force of the shaft 7. Such a weight is adopted when a casing of the device itself is vibrated by a portable small radio caller (for example, a mobile phone or the like).

このようなモータ１の場合、整流子１０からコイルＣへの適切な給電を図るために、コイルＣの電線Ｗを整流子１０の整流子片１１に確実に接続させる必要がある。   In the case of such a motor 1, it is necessary to reliably connect the electric wire W of the coil C to the commutator piece 11 of the commutator 10 in order to appropriately supply power from the commutator 10 to the coil C.

図４〜図７に示すように、整流子１０は、シャフト７に固定されると共に、円形の鍔部１２ａを有する樹脂製のスリーブ１２と、銅製薄板のプレス成形によって作られた３枚の整流子片１１と、整流子片１１をスリーブ１２に固定させるための固定リング１３とからなる。さらに、各整流子片１１は、スリーブ１２の筒部１２ｂの表面に沿って配置される断面円弧状のベース部１４と、ベース部１４の端部から起立すると共に、円形の鍔部１２ａの外周面１２ｃから先端部分が突出するライザ部１５と、ライザ部１５の先端部分の両側に設けられると共に、スリーブ１２の鍔部１２ａの外周面１２ｃに隣接する電線引掛け用切り込み部１６とからなる。この切り込み部１６は、電線Ｗの引っ掛けを良好にするためにＪ字状に形成されている。   As shown in FIGS. 4 to 7, the commutator 10 is fixed to the shaft 7, and the three sleeves made by press molding a resin sleeve 12 having a circular flange 12 a and a copper thin plate. It consists of a child piece 11 and a fixing ring 13 for fixing the commutator piece 11 to the sleeve 12. Furthermore, each commutator piece 11 rises from an arcuate cross-sectional base portion 14 disposed along the surface of the cylindrical portion 12b of the sleeve 12, and an outer periphery of the circular flange portion 12a. The riser portion 15 has a tip portion protruding from the surface 12c, and is provided on both sides of the tip portion of the riser portion 15, and includes a wire hooking cut portion 16 adjacent to the outer peripheral surface 12c of the flange portion 12a of the sleeve 12. The cut portion 16 is formed in a J shape so that the wire W can be easily hooked.

ライザ部１５の先端部分の両側には、略三角形状の張出し部１５ａが設けられ、この張出し部１５ａによって、電線引掛け用切り込み部１６の裾野を長くすることができる。さらに、張出し部１５ａの頂部が、鍔部１２ａの外周面１２ｃから径方向に突出しないようにすなわち鍔部１２ａで隠れるように、ライザ部１５は鍔部１２ａのライザ収容凹部１２ｄ内に収容されるので、切り込み部１６をスリーブ１２の鍔部１２ａの外周面１２ｃに隣接して配置させることができる。また、コイルＣの電線Ｗの張力で整流子片１１のライザ部１５が回転子６の方向に引っ張られた場合であっても、ライザ部１５は鍔部１２ａによって十分に支持されるので、ライザ部１５が回転子６の方向に折れ曲がることはない。   A substantially triangular projecting portion 15a is provided on both sides of the leading end portion of the riser portion 15, and the base of the wire hooking cut portion 16 can be lengthened by the projecting portion 15a. Further, the riser portion 15 is accommodated in the riser accommodating recess 12d of the flange portion 12a so that the top portion of the overhang portion 15a does not protrude in the radial direction from the outer peripheral surface 12c of the flange portion 12a, that is, is hidden by the flange portion 12a. Therefore, the cut portion 16 can be disposed adjacent to the outer peripheral surface 12 c of the flange portion 12 a of the sleeve 12. Even when the riser portion 15 of the commutator piece 11 is pulled in the direction of the rotor 6 by the tension of the electric wire W of the coil C, the riser portion 15 is sufficiently supported by the flange portion 12a. The part 15 does not bend in the direction of the rotor 6.

このようなモータ１では、鍔部１２ａの円形の外周面１２ｃと整流子片１１のＪ字状の切り込み部１６との協働により、電線Ｗを切り込み部１６に引っ掛ける際の電線Ｗの引っ掛かり精度が向上し、整流子片１１に電線Ｗを半田付けＨ（図１参照）する際の半田不良の発生が適切に防止される。   In such a motor 1, the hooking accuracy of the electric wire W when the electric wire W is hooked on the cut portion 16 by the cooperation of the circular outer peripheral surface 12 c of the flange portion 12 a and the J-shaped cut portion 16 of the commutator piece 11. And the occurrence of defective soldering when the electric wire W is soldered H (see FIG. 1) to the commutator piece 11 is appropriately prevented.

このような円形の鍔部１２ａをもったスリーブ１２においては、モータ１を小型化させるに伴って鉄心５と円形の鍔部１２ａとの隙間寸法が小さくなって、コイルＣの巻数が少なくなってしまうといった不具合がある。そこで、シャフト７の軸線方向において、円形の鍔部１２ａには、鉄心５の各ポール５ａに巻かれた各コイルＣと対向する位置に、コイルＣの逃がしとして利用される凹部２０が設けられている（図２参照）。これによって、モータ１の小型化を促進させる上で、コイルＣの巻数を減らすことなく、所望のモータトルクを得ることができる。そして、鍔部１２ａに凹部２０を形成することは、モータが小型化されればされる程、有効である。   In the sleeve 12 having such a circular flange 12a, the size of the gap between the iron core 5 and the circular flange 12a is reduced as the motor 1 is reduced in size, and the number of turns of the coil C is reduced. There is a problem such as. Therefore, in the axial direction of the shaft 7, the circular flange portion 12 a is provided with a recess 20 that is used as a relief of the coil C at a position facing each coil C wound around each pole 5 a of the iron core 5. (See FIG. 2). As a result, when the miniaturization of the motor 1 is promoted, a desired motor torque can be obtained without reducing the number of turns of the coil C. And it is so effective that the recessed part 20 is formed in the collar part 12a, so that a motor is miniaturized.

また、隣接する整流子片１１，１１のライザ部１５，１５間において、凹部２０は、鍔部１２ａの外周から切り込まれるような形状を有する。このような構成は、鍔部の強度が最大限発揮される円形の鍔部１２ａを採用するにあたって、スリーブ１２の小型化を図ることができ、モータを小型化する上で最適である。   Moreover, the recessed part 20 has a shape cut | disconnected from the outer periphery of the collar part 12a between the riser parts 15 and 15 of the adjacent commutator pieces 11 and 11. FIG. Such a configuration can reduce the size of the sleeve 12 when adopting the circular flange 12a that maximizes the strength of the flange, and is optimal for downsizing the motor.
