上記のようなブラシ装置では、モータ自身の駆動による振動や車両振動などによって端子部材が振動（共振）してしまうと、その端子部材の振動によって前記第１接続部や第２接続部に断線などが生じるおそれがあり、また、端子部材の振動音が異音となるおそれもある。特に、端子部材の第１接続部及び第２接続部が、チョークコイルの軸線方向（モータ軸方向）の中央に対して一方側、他方側にそれぞれ設けられた構成では、端子部材が第１接続部から第２接続部にかけて長く延びる形状になることから、端子部材が振動しやすく（振幅が大きくなりやすく）なってしまう。その結果、上記の断線などの問題が生じるおそれが高くなる。 In the brush device as described above, when the terminal member vibrates (resonates) due to vibration driven by the motor itself or vehicle vibration, the vibration of the terminal member causes disconnection of the first connection portion or the second connection portion. Also, the vibration noise of the terminal member may become an abnormal noise. In particular, in a configuration in which the first connection portion and the second connection portion of the terminal member are provided on one side and the other side of the center of the choke coil in the axial direction (motor axial direction), the terminal member is first connected. Since the shape extends long from the portion to the second connecting portion, the terminal member tends to vibrate (the amplitude tends to increase). As a result, there is a high possibility that the above-mentioned problems such as disconnection will occur.

本発明は、上記課題を解決するためになされたものであって、その目的は、チョークコイルと接続された端子部材の振動を抑制できるブラシ装置及びモータを提供することにある。 The present invention has been made to solve the above problems, and an object of the present invention is to provide a brush device and a motor capable of suppressing vibration of a terminal member connected to a choke coil.

The choke coil holding portion 51 has an arc shape that follows the outer peripheral surface of the choke coil 43, and has a guide surface 52 that guides the assembly of the choke coil 43. The guide surface 52 is formed on the outer peripheral surface of the peripheral wall portion 36a. Further, the choke coil holding portion 51 has a holding piece 53 that faces the guide surface 52 with the choke coil 43 interposed therebetween.

More specifically, in the Y-axis direction, the brush side connection portion 63, the choke coil 43, and the thermistor side connection portion 73 are arranged side by side in this order. Further, the thermistor side connection portion 73 and the brush side connection portion 63 are located on the same plane (XY plane) parallel to the axial direction.

ここで、図３、図５及び図６に示すように、前記整流子収容部３６の周壁部３６ａの外周面（より詳しくはＺ軸方向の側面３６ｄ）には、第２端子部材４２の長尺部７４の下端部の板面に対してＺ軸方向に当接する当接支持部８１が設けられている。当接支持部８１は、周壁部３６ａの側面３６ｄからＺ軸方向（長尺部７４の板厚方向）に突出するベース部８２と、ベース部８２のＹ軸方向の中央からＺ軸方向（長尺部７４の板厚方向）に突出する当接凸部８３とを有している。当接凸部８３は、軸方向視（Ｘ軸方向視）において半円状に突出している（図６参照）。また、当接凸部８３はチョークコイル４３の軸線方向（Ｘ軸方向）に沿って直線状に延び、当接支持部８１の下端部は、基部３４の収容凹部３４ｂの底面と繋がっている。また、当接支持部８１（ベース部８２及び当接凸部８３）の上端部（軸方向の反基部側の端部）には、軸方向の基部３４（収容凹部３４ｂ）側に向かうにつれて周壁部３６ａの側面３６ｄから離れるように傾斜する傾斜面８４が形成されている。つまり、傾斜面８４は、長尺部７４の延在方向（Ｘ軸方向）に対して傾斜している。そして、当接凸部８３の突出先端（Ｚ軸方向の先端）は、第２端子部材４２の長尺部７４が板厚方向（Ｚ軸方向）に撓んだ状態で、該長尺部７４の下端部（コイル側接続部７５）の板面と当接している（図５参照）。 Here, as shown in FIGS. 3, 5, and 6, the length of the second terminal member 42 is on the outer peripheral surface (more specifically, the side surface 36d in the Z-axis direction) of the peripheral wall portion 36a of the commutator accommodating portion 36. A contact support portion 81 that abuts in the Z-axis direction with respect to the plate surface at the lower end of the scale portion 74 is provided. The contact support portion 81 has a base portion 82 protruding in the Z-axis direction (the plate thickness direction of the long portion 74) from the side surface 36d of the peripheral wall portion 36a, and a Z-axis direction (long) from the center of the base portion 82 in the Y-axis direction. It has a contact convex portion 83 protruding in the plate thickness direction of the scale portion 74). The contact convex portion 83 projects in a semicircular shape in the axial direction (X-axis direction view) (see FIG. 6). Further, the contact convex portion 83 extends linearly along the axial direction (X-axis direction) of the choke coil 43, and the lower end portion of the contact support portion 81 is connected to the bottom surface of the accommodating recess 34b of the base portion 34. Further, at the upper end portion (end portion on the anti-base portion side in the axial direction) of the contact support portion 81 (base portion 82 and contact convex portion 83), a peripheral wall is provided toward the base portion 34 (accommodation recess 34b) in the axial direction. An inclined surface 84 is formed so as to be inclined away from the side surface 36d of the portion 36a. That is, the inclined surface 84 is inclined with respect to the extending direction (X-axis direction) of the long portion 74. The protruding tip (tip in the Z-axis direction) of the contact convex portion 83 is a state in which the long portion 74 of the second terminal member 42 is bent in the plate thickness direction (Z-axis direction). It is in contact with the plate surface of the lower end portion (coil side connection portion 75) of the above (see FIG. 5).

上記の電気部品４０によれば、コネクタ部３３に接続される外部コネクタからの供給電力は、ターミナルＴ、サーミスタ４４、第２端子部材４２、チョークコイル４３、第１端子部材４１、ピッグテール３８ａの順に流れて、ブラシ３８に供給されるようになっている。すなわち、ターミナルＴ、サーミスタ４４、第２端子部材４２、チョークコイル４３、第１端子部材４１及びピッグテール３８ａが、コネクタ部３３からブラシ３８にかけての給電回路を構成している。 According to the above-mentioned electric component 40, the power supplied from the external connector connected to the connector portion 33 is in the order of the terminal T, the thermistor 44, the second terminal member 42, the choke coil 43, the first terminal member 41, and the pigtail 38a. It flows and is supplied to the brush 38. That is, the terminal T, the thermistor 44, the second terminal member 42, the choke coil 43, the first terminal member 41, and the pigtail 38a form a power feeding circuit from the connector portion 33 to the brush 38.

なお、前述の図示しない側の電気部品（前記奥側の電気部品）は、手前側の電気部品４０と同様の第１端子部材４１、第２端子部材４２、チョークコイル４３を備え（サーミスタ４４は非搭載）、第２端子部材４２における接続部７３がホルダ部材３１に埋設されたターミナルと接続されるようになっている。すなわち、当該奥側の電気部品にて構成されるコネクタ部３３からブラシ３８にかけての給電回路は、手前側の電気部品４０に対してサーミスタ４４を省略した構成を有している。また、当該奥側の電気部品においても、第２端子部材４２の長尺部７４の下端部が整流子収容部３６の周壁部３６ａに形成された当接支持部（上記当接支持部８１と略同構成）と当接している。 The above-mentioned electric component on the side not shown (the electric component on the back side) includes a first terminal member 41, a second terminal member 42, and a choke coil 43 similar to the electric component 40 on the front side (thermistor 44 is a thermistor 44). (Not mounted), the connection portion 73 of the second terminal member 42 is connected to the terminal embedded in the holder member 31. That is, the power supply circuit from the connector portion 33 composed of the electric components on the back side to the brush 38 has a configuration in which the thermistor 44 is omitted with respect to the electric components 40 on the front side. Further, also in the electric component on the back side, the lower end portion of the long portion 74 of the second terminal member 42 is formed on the peripheral wall portion 36a of the commutator accommodating portion 36 (with the contact support portion 81). It is in contact with (substantially the same configuration).

次に、ブラシ装置３０の製造方法（ホルダ部材３１に対する電気部品４０の組付態様）について説明する。
まず、図３に示すように、互いに分離される前の第１及び第２端子部材４１，４２に対して、チョークコイル４３、サーミスタ４４及びブラシ３８（ピッグテール３８ａ）を接続する接続工程を行う。これにより、互いに分離される前の第１及び第２端子部材４１，４２、チョークコイル４３、サーミスタ４４及びブラシ３８（ピッグテール３８ａ）からなる一体部品Ｐ（ＡＳＳＹ部品）が成形される。 Next, a method of manufacturing the brush device 30 (a mode of assembling the electric component 40 to the holder member 31) will be described.
First, as shown in FIG. 3, a connection step of connecting the choke coil 43, the thermistor 44, and the brush 38 (pigtail 38a) to the first and second terminal members 41 and 42 before they are separated from each other is performed. As a result, an integral part P (ASSY part) composed of the first and second terminal members 41 and 42, the choke coil 43, the thermistor 44 and the brush 38 (pigtail 38a) before being separated from each other is formed.

次に、接続工程によって成形された一体部品Ｐをホルダ本体部３２に組み付ける組付工程を行う。この組付工程では、第１端子部材４１の第１部位６１（又は第２端子部材４２の第１部位７１）をチャックなどの治具（図示略）で保持する。そして、チョークコイル４３の軸線方向（Ｘ軸方向）に沿って芯材４５の第２端面４５ｂ側から一体部品Ｐをホルダ本体部３２に組み付ける。 Next, an assembling step of assembling the integrated part P formed by the connecting step to the holder main body 32 is performed. In this assembly step, the first portion 61 of the first terminal member 41 (or the first portion 71 of the second terminal member 42) is held by a jig (not shown) such as a chuck. Then, the integrated component P is assembled to the holder main body 32 from the second end surface 45b side of the core material 45 along the axial direction (X-axis direction) of the choke coil 43.

この組み付け時において、チョークコイル４３（巻線４６）の下端部が保持片５３と当接する位置に到達したときには、長尺部７４の下端部が当接支持部８１に当接しない。このため、まず、チョークコイル４３がチョークコイル保持部５１の案内面５２と保持片５３との間に挿入され、その後さらにＸ軸方向の基部３４側に一体部品Ｐが押し込まれることで、長尺部７４の下端部が当接支持部８１に当接される。このとき、長尺部７４の下端部は当接支持部８１の傾斜面８４と当接し、該傾斜面８４によって周壁部３６ａの側面３６ｄから離間する方向（Ｚ軸方向）に案内される。これにより、図５に示すように、長尺部７４が板厚方向（Ｚ軸方向）に湾曲され、その湾曲状態で長尺部７４（本実施形態ではコイル側接続部７５）の板面と当接凸部８３のＺ軸方向の突出先端とが当接される。 At the time of this assembly, when the lower end of the choke coil 43 (winding 46) reaches the position where it comes into contact with the holding piece 53, the lower end of the long portion 74 does not come into contact with the contact support portion 81. Therefore, first, the choke coil 43 is inserted between the guide surface 52 of the choke coil holding portion 51 and the holding piece 53, and then the integrated component P is further pushed toward the base 34 side in the X-axis direction, so that the length is long. The lower end of the portion 74 is brought into contact with the contact support portion 81. At this time, the lower end portion of the long portion 74 abuts on the inclined surface 84 of the contact support portion 81, and is guided by the inclined surface 84 in a direction away from the side surface 36d of the peripheral wall portion 36a (Z-axis direction). As a result, as shown in FIG. 5, the long portion 74 is curved in the plate thickness direction (Z-axis direction), and in the curved state, the long portion 74 and the plate surface of the long portion 74 (coil side connection portion 75 in this embodiment) are formed. The protruding tip of the contact convex portion 83 in the Z-axis direction is brought into contact with the contact convex portion 83.

また、当該組付工程において、第１端子部材４１の当接部６６を芯材４５の第１端面４５ａに当接させる。これにより、チョークコイル４３がチョークコイル保持部５１の案内面５２と保持片５３との間に挿入される際に、該チョークコイル保持部５１側から受ける反作用の力を、第１端子部材４１の当接部６６で受けることができる。その結果、当該組付工程においてチョークコイル４３と第１及び第２端子部材４１，４２との接続部位に掛かる応力が緩和され、該接続部位における断線などを抑制できる。なお、チョークコイル４３の組付状態において、芯材４５の第２端面４５ｂがホルダ本体部３２の基部３４（収容凹部３４ｂの底面）とＸ軸方向に当接してもよく、また、離間していてもよい。 Further, in the assembling step, the contact portion 66 of the first terminal member 41 is brought into contact with the first end surface 45a of the core material 45. As a result, when the choke coil 43 is inserted between the guide surface 52 of the choke coil holding portion 51 and the holding piece 53, the reaction force received from the choke coil holding portion 51 side is applied to the first terminal member 41. It can be received at the contact portion 66. As a result, the stress applied to the connection portions between the choke coil 43 and the first and second terminal members 41 and 42 in the assembly step is relaxed, and disconnection at the connection portions can be suppressed. In the assembled state of the choke coil 43, the second end surface 45b of the core material 45 may come into contact with the base portion 34 (bottom surface of the accommodating recess 34b) of the holder main body portion 32 in the X-axis direction, and may be separated from each other. You may.

一体部品Ｐにおけるチョークコイル４３をチョークコイル保持部５１に挿入した後、ブラシ３８をブラシ収容部３７に収容する。また、一体部品Ｐにおけるサーミスタ４４の第２端子４４ｂをホルダ部材３１側のターミナルＴと接続する。 After inserting the choke coil 43 in the integral component P into the choke coil holding portion 51, the brush 38 is accommodated in the brush accommodating portion 37. Further, the second terminal 44b of the thermistor 44 in the integrated component P is connected to the terminal T on the holder member 31 side.

その後、切断予定部位Ｃｘを切断して第１端子部材４１と第２端子部材４２とを切り離す。これにより、ターミナルＴからブラシ３８にかけてサーミスタ４４及びチョークコイル４３が直列に接続された回路構成となる。 After that, the cut portion Cx is cut to separate the first terminal member 41 and the second terminal member 42. As a result, the circuit configuration is such that the thermistor 44 and the choke coil 43 are connected in series from the terminal T to the brush 38.

なお、組み付け後の状態において、第１端子部材４１の当接部６６が芯材４５の第１端面４５ａと当接している場合、第１端子部材４１に加わる振動などの力を当接部６６からチョークコイル４３側に逃がすことができる。これにより、チョークコイル４３の第１端末線４６ａとコイル側接続部６４との接続部位に掛かる応力が緩和されるようになっている。 In the state after assembly, when the contact portion 66 of the first terminal member 41 is in contact with the first end surface 45a of the core material 45, a force such as vibration applied to the first terminal member 41 is applied to the contact portion 66. Can be released to the choke coil 43 side.

(1) The long portion 74 of the second terminal member 42 has a long shape extending from the coil side connection portion 75 to the thermistor side connection portion 73, and the holder main body portion 32 has the long portion 74 in the plate thickness direction (Z). A contact support portion 81 that comes into contact with the plate surface of the long portion 74 while being bent in the axial direction) is provided. According to the above aspect, the vibration of the second terminal member 42 can be suppressed by the contact support portion 81, and as a result, the generation of abnormal noise due to disconnection or vibration in the coil side connection portion 75 or the thermistor side connection portion 73 can be suppressed. Further, in the present embodiment, since the contact support portion 81 abuts on the long portion 74 of the second terminal member 42, the long portion 74 having a long shape whose amplitude tends to increase when vibrated is compared with the long portion 74. Vibration can be suppressed effectively.

また、本実施形態では、第２端子部材４２の支持について、組み付け時に第２端子部材４２の長尺部７４を当接支持部８１に当てて撓ませるだけで済むため、第２端子部材４２の一部をホルダ本体部３２側に圧入固定する構成に比べて組み付け荷重を低減することができ、組み付け性を向上できる。 Further, in the present embodiment, regarding the support of the second terminal member 42, since it is only necessary to apply the long portion 74 of the second terminal member 42 to the contact support portion 81 and bend it at the time of assembly, the second terminal member 42 may be bent.

According to the above aspect, in the configuration in which the choke coil 43 and the second terminal member 42 are arranged on the outer peripheral side of the peripheral wall portion 36a, the plate surface of the long portion 74 of the second terminal member 42 is orthogonal to the radial direction, so that the length is long. The long portion 74 can be arranged close to the peripheral wall portion 36a in such a manner that the plate surface of the measuring portion 74 faces the outer peripheral surface of the peripheral wall portion 36a, which can contribute to the miniaturization of the brush device 30 in the radial direction.

（３）当接支持部８１は周壁部３６ａの外周面から径方向外側に突出し、その突出先端（当接凸部８３の先端）で長尺部７４の板面と当接している。これにより、当接支持部８１を長尺部７４の板面に対して好適に当接させることができ、長尺部７４の振動を好適に抑制できる。 (3) The contact support portion 81 projects radially outward from the outer peripheral surface of the peripheral wall portion 36a, and is in contact with the plate surface of the long portion 74 at the protruding tip (tip of the contact convex portion 83). As a result, the contact support portion 81 can be suitably brought into contact with the plate surface of the long portion 74, and the vibration of the long portion 74 can be suitably suppressed.

（４）第２端子部材４２の長尺部７４は、その板面がチョークコイル４３と対向しないように配置されている。これにより、長尺部７４とチョークコイル４３との間に寄生容量が生じることを抑制できる。従って、第２端子部材４２の長尺部７４とチョークコイル４３との間でノイズがバイパスしてしまうことを抑制でき、その結果、ＥＭＣ性能の向上に寄与できる。 (4) The long portion 74 of the second terminal member 42 is arranged so that its plate surface does not face the choke coil 43. As a result, it is possible to suppress the occurrence of parasitic capacitance between the long portion 74 and the choke coil 43. Therefore, it is possible to prevent noise from bypassing between the long portion 74 of the second terminal member 42 and the choke coil 43, and as a result, it is possible to contribute to the improvement of EMC performance.
