ところで、近年、車両には様々な電子機器が多数搭載されているため、ＥＭＣ（Electromagnetic Compatibility）対策の観点から、上記のようなアクチュエータには、給電端子部と接点部との間にノイズを吸収する雑防素子を接続することが好ましい。しかしながら、上記したアクチュエータでは、モータは、ヨークハウジングにおける回転軸の基端側の端面、即ち、ヨークハウジングにおける一対の接点部が設けられた側の端部をコネクタ部に隣接させて筐体の内部に収容されている。そのため、コネクタ部の内側に配置される一対の給電端子部とモータの一対の接点部とが近接している。従って、給電端子部と接点部との間、即ち、ヨークハウジングにおける回転軸の基端側の端面とコネクタ部との間に雑防素子を配置するスペースを確保することが困難であった。そのため、このようなアクチュエータにおいてどのように雑防素子を配置するかが課題となっていた。 By the way, in recent years, since many various electronic devices are mounted on vehicles, from the viewpoint of EMC (Electromagnetic Compatibility) countermeasures, the above-mentioned actuator absorbs noise between the power feeding terminal portion and the contact portion. It is preferable to connect a miscellaneous protection element. However, in the above-mentioned actuator, the motor is inside the housing with the end face on the base end side of the rotating shaft in the yoke housing, that is, the end portion of the yoke housing on the side where the pair of contact portions are provided, adjacent to the connector portion. Is housed in. Therefore, the pair of power feeding terminal portions arranged inside the connector portion and the pair of contact portions of the motor are close to each other. Therefore, it is difficult to secure a space for arranging the miscellaneous protection element between the power feeding terminal portion and the contact portion, that is, between the end surface on the base end side of the rotating shaft in the yoke housing and the connector portion. Therefore, how to arrange the miscellaneous protection element in such an actuator has been an issue.

本開示の目的は、コネクタ部の内側に配置される給電端子部とヨークハウジングにおける回転軸の基端側の端部に設けられた接点部との間に雑防素子を接続することができるアクチュエータを提供することにある。 An object of the present disclosure is an actuator capable of connecting a miscellaneous protection element between a power feeding terminal portion arranged inside a connector portion and a contact portion provided at an end portion of a yoke housing on the base end side of a rotating shaft. Is to provide.

上記課題を解決するアクチュエータは、外部コネクタが接続されるコネクタ部（４１）を有する筐体（１１）と、ヨークハウジング（５１）と前記ヨークハウジングの内部に基端部が収容され且つ先端部が前記ヨークハウジングから突出した回転軸（５４）と前記ヨークハウジングにおける前記回転軸の基端側の端部に設けられた一対の接点部（６１，６２）とを有し前記ヨークハウジングにおける前記回転軸の基端側の端面と前記コネクタ部とを隣接させて前記筐体の内部に収容されたモータ（１２）と、前記筐体の内部に収容され前記回転軸の回転を減速して出力する減速機構（１３）と、一対の前記接点部に電気的に接続される一対の接点端子部（１０１，１２１）と、前記コネクタ部の内側に配置される一対の給電端子部（１０２，１２２）と、一方の前記給電端子部と一方の前記接点端子部とを電気的に接続する第１配線部（１０３）と、他方の前記給電端子部と他方の前記接点端子部とを電気的に接続する第２配線部（１２３）と、前記第１配線部及び前記第２配線部の少なくとも一方に電気的に接続されることにより前記モータと直列もしくは並列に接続される雑防素子（８３，８５，８６）とを有し前記筐体に収容された給電装置（１４）と、を備え、前記第１配線部及び前記第２配線部は、各々に電気的に接続された前記接点端子部から前記回転軸の先端側に延びた後に前記回転軸の基端側に折り返して各々に電気的に接続された前記給電端子部まで延びている。 The actuator that solves the above problems includes a housing (11) having a connector portion (41) to which an external connector is connected, a yoke housing (51), and a base end portion housed inside the yoke housing and a tip portion thereof. The rotating shaft in the yoke housing has a rotating shaft (54) protruding from the yoke housing and a pair of contact portions (61, 62) provided at the end of the rotating shaft on the proximal end side of the yoke housing. The motor (12) housed inside the housing with the end face on the base end side adjacent to the connector portion, and the deceleration housed inside the housing to slow down and output the rotation of the rotating shaft. A mechanism (13), a pair of contact terminal portions (101, 121) electrically connected to the pair of the contact portions, and a pair of power feeding terminal portions (102, 122) arranged inside the connector portion. , The first wiring portion (103) that electrically connects one of the power feeding terminal portions and the one of the contact terminal portions, and the other of the feeding terminal portions and the other of the contact terminal portions are electrically connected. Miscellaneous protection elements (83, 85,) connected in series or in parallel with the motor by being electrically connected to the second wiring unit (123) and at least one of the first wiring unit and the second wiring unit. A power feeding device (14) having 86) and housed in the housing is provided, and the first wiring portion and the second wiring portion are connected to the contact terminal portion electrically connected to the first wiring portion and the second wiring portion. After extending to the tip end side of the rotating shaft, it is folded back to the base end side of the rotating shaft and extends to the feeding terminal portion electrically connected to each.

上記態様によれば、第１配線部は、同第１配線部に電気的に接続された接点端子部から回転軸の先端側に延びることによりコネクタ部から離れる方向に延びることになる。その後、同第１配線部は、回転軸の基端側に折り返すことによりコネクタ部の方へ延びて同第１配線部に電気的に接続される給電端子部に至る。同様に、第２配線部は、同第２配線部に電気的に接続された接点端子部から回転軸の先端側に延びることによりコネクタ部から離れる方向に延びることになる。その後、同第２配線部は、回転軸の基端側に折り返すことによりコネクタ部の方へ延びて同第２配線部に電気的に接続される給電端子部に至る。従って、コネクタ部から回転軸の先端側に離れた位置に雑防素子を配置しても、当該雑防素子を第１配線部及び第２配線部の少なくとも一方に電気的に接続することにより給電端子部と接点部との間に電気的に接続することができる。従って、ヨークハウジングにおける回転軸の基端側の端面とコネクタ部とが隣接しているためにヨークハウジングにおける回転軸の基端側の端面とコネクタ部との間に雑防素子を配置するスペースが無くとも、コネクタ部の内側に配置される給電端子部とヨークハウジングにおける回転軸の基端側の端部に設けられた接点部との間に雑防素子を接続することができる。 According to the above aspect, the first wiring portion extends in the direction away from the connector portion by extending from the contact terminal portion electrically connected to the first wiring portion toward the tip end side of the rotating shaft. After that, the first wiring portion extends toward the connector portion by folding back toward the base end side of the rotating shaft, and reaches the feeding terminal portion electrically connected to the first wiring portion. Similarly, the second wiring portion extends in a direction away from the connector portion by extending toward the tip end side of the rotating shaft from the contact terminal portion electrically connected to the second wiring portion. After that, the second wiring portion extends toward the connector portion by folding back toward the base end side of the rotating shaft, and reaches the feeding terminal portion electrically connected to the second wiring portion. Therefore, even if the miscellaneous protection element is arranged at a position away from the connector portion on the tip side of the rotating shaft, power is supplied by electrically connecting the miscellaneous protection element to at least one of the first wiring portion and the second wiring portion. It can be electrically connected between the terminal part and the contact part. Therefore, since the end surface on the proximal end side of the rotary shaft in the yoke housing and the connector portion are adjacent to each other, there is a space for arranging the miscellaneous protection element between the end surface on the proximal end side of the rotary shaft in the yoke housing and the connector portion. Even if it is not present, the miscellaneous protection element can be connected between the power feeding terminal portion arranged inside the connector portion and the contact portion provided at the end portion of the yoke housing on the base end side of the rotating shaft.

（１）第１配線部１０３及び第２配線部１２３は、各々が電気的に接続された第１接点端子部１０１もしくは第２接点端子部１２１から回転軸５４の先端側に延びた後に回転軸５４の基端側に折り返して各々が接続された第１給電端子部１０２もしくは第２給電端子部１２２まで延びている。 The effect of this embodiment will be described.
(1) The first wiring portion 103 and the second wiring portion 123 extend from the first contact terminal portion 101 or the second contact terminal portion 121, each of which is electrically connected, to the tip end side of the rotation shaft 54, and then the rotation shaft. It is folded back toward the base end side of 54 and extends to the first power feeding terminal portion 102 or the second feeding terminal portion 122 to which each is connected.

そのため、第１配線部１０３は、同第１配線部１０３に電気的に接続された第１接点端子部１０１から回転軸５４の先端側に延びることによりコネクタ部４１から離れる方向に延びることになる。その後、同第１配線部１０３は、回転軸５４の基端側に折り返すことによりコネクタ部４１の方へ延びて同第１配線部１０３に電気的に接続される第１給電端子部１０２に至る。同様に、第２配線部１２３は、同第２配線部１２３に電気的に接続された第２接点端子部１２１から回転軸５４の先端側に延びることによりコネクタ部４１から離れる方向に延びることになる。その後、同第２配線部１２３は、回転軸５４の基端側に折り返すことによりコネクタ部４１の方へ延びて同第２配線部１２３に電気的に接続される第２給電端子部１２２に至る。従って、コネクタ部４１から回転軸５４の先端側に離れた位置に雑防素子８３を配置しても、当該雑防素子８３を第１配線部１０３に電気的に接続することにより第１給電端子部１０２と接点部６１との間に電気的に接続することができる。同様に、コネクタ部４１から回転軸５４の先端側に離れた位置に雑防素子８５を配置しても、当該雑防素子８５を第２配線部１２３に電気的に接続することにより第２給電端子部１２２と接点部６２との間に電気的に接続することができる。同様に、コネクタ部４１から回転軸５４の先端側に離れた位置に雑防素子８６を配置しても、当該雑防素子８６を第１配線部１０３及び第２配線部１２３に電気的に接続することにより第１及び第２給電端子部１０２，１２２と接点部６１，６２との間に電気的に接続することができる。本実施形態のアクチュエータ１０は、ヨーク５１における回転軸５４の基端側の端面とコネクタ部４１とが隣接しているためにヨーク５１における回転軸５４の基端側の端面とコネクタ部４１との間に雑防素子８３，８５，８６を配置するスペースが無い構成である。しかしながら、上記したように、コネクタ部４１の内側に配置される第１及び第２給電端子部１０２，１２２とヨーク５１における回転軸５４の基端側の端部に設けられた接点部６１，６２との間に雑防素子８３，８５，８６を接続することができる。 Therefore, the first wiring portion 103 extends in the direction away from the connector portion 41 by extending from the first contact terminal portion 101 electrically connected to the first wiring portion 103 toward the tip end side of the rotating shaft 54. .. After that, the first wiring portion 103 extends toward the connector portion 41 by folding back toward the base end side of the rotating shaft 54, and reaches the first feeding terminal portion 102 electrically connected to the first wiring portion 103. .. Similarly, the second wiring portion 123 extends in a direction away from the connector portion 41 by extending from the second contact terminal portion 121 electrically connected to the second wiring portion 123 toward the tip end side of the rotating shaft 54. Become. After that, the second wiring portion 123 extends toward the connector portion 41 by folding back toward the base end side of the rotating shaft 54, and reaches the second feeding terminal portion 122 electrically connected to the second wiring portion 123. .. Therefore, even if the miscellaneous protection element 83 is arranged at a position away from the connector portion 41 on the tip end side of the rotating shaft 54, the miscellaneous protection element 83 is electrically connected to the first wiring portion 103 to provide a first power supply terminal. It can be electrically connected between the portion 102 and the contact portion 61. Similarly, even if the miscellaneous protection element 85 is arranged at a position away from the connector portion 41 on the tip end side of the rotating shaft 54, the miscellaneous protection element 85 is electrically connected to the second wiring portion 123 to supply a second power supply. It can be electrically connected between the terminal portion 122 and the contact portion 62. Similarly, even if the miscellaneous protection element 86 is arranged at a position away from the connector portion 41 on the tip side of the rotating shaft 54, the miscellaneous protection element 86 is electrically connected to the first wiring portion 103 and the second wiring portion 123. By doing so, it is possible to electrically connect between the first and second power feeding terminal portions 102 and 122 and the contact portions 61 and 62. In the actuator 10 of the present embodiment, since the end surface on the proximal end side of the rotary shaft 54 in the yoke 51 and the connector portion 41 are adjacent to each other, the end surface on the proximal end side of the rotary shaft 54 in the yoke 51 and the connector portion 41 There is no space for arranging the miscellaneous protection elements 83, 85, 86 in between. However, as described above, the first and second power feeding terminal portions 102, 122 arranged inside the connector portion 41 and the contact portions 61, 62 provided at the end portions of the yoke 51 on the proximal end side of the rotating shaft 54. The miscellaneous protection elements 83, 85, 86 can be connected to and from.

（２）給電装置１４は、モータ１２と直列に接続されるように第１配線部１０３に電気的に接続されたＰＴＣサーミスタ８４を有する。ＰＴＣサーミスタ８４は、第１配線部１０３に電気的に接続された雑防素子８３，８６よりも第１給電端子部１０２に近い位置に接続されている。そのため、ＰＴＣサーミスタ８４によって、モータ１２だけでなく、同ＰＴＣサーミスタ８４が接続された第１配線部１０３に電気的に接続された雑防素子８３，８６にも過電流が供給されることが抑制される。 (2) The power feeding device 14 has a PTC thermistor 84 electrically connected to the first wiring unit 103 so as to be connected in series with the motor 12. The PTC thermistor 84 is connected to a position closer to the first power feeding terminal portion 102 than the miscellaneous protection elements 83 and 86 electrically connected to the first wiring portion 103. Therefore, the PTC thermistor 84 suppresses the supply of overcurrent not only to the motor 12 but also to the miscellaneous protection elements 83 and 86 electrically connected to the first wiring portion 103 to which the PTC thermistor 84 is connected. Will be done.

（３）筐体１１は、長手方向を有する形状をなし、筐体１１の長手方向に延びる一対の壁部２３ｃ，２３ｄを有するとともに筐体１１の長手方向の端部にコネクタ部４１を有する。モータ１２は、一対の壁部２３ｃ，２３ｄの間で回転軸５４の回転軸線Ｌ１が筐体１１の長手方向に対して傾斜することにより回転軸５４の先端が一方の壁部２３ｃよりも他方の壁部２３ｄに近づいた状態で筐体１１の内部に収容されている。減速機構１３は、回転軸５４と同軸状に設けられるウォーム７１と、ウォーム７１に噛合する第１減速ギヤ７２とを含む。第１減速ギヤ７２は、回転軸５４と一方の壁部２３ｃとの間に配置されている。そのため、一対の壁部２３ｃ，２３ｄの間の間隔を広くしなくとも、回転軸５４の先端側の部位と一方の壁部２３ｃとの間の空間を広くすることができる。そして、回転軸５４の先端側の部位と一方の壁部２３ｃとの間の当該空間に第１減速ギヤ７２を配置することにより、回転軸５４の回転軸線Ｌ１が筐体の長手方向と平行になるようにモータ１２が筐体に収容される場合に比べて、アクチュエータ１０を筐体１１の長手方向と直交する方向、即ち一対の壁部２３ｃ，２３ｄが対向する方向に小型化できる。 (3) The housing 11 has a shape having a longitudinal direction, has a pair of wall portions 23c and 23d extending in the longitudinal direction of the housing 11, and has a connector portion 41 at an end portion in the longitudinal direction of the housing 11. In the motor 12, the rotation axis L1 of the rotation shaft 54 is inclined with respect to the longitudinal direction of the housing 11 between the pair of wall portions 23c and 23d, so that the tip of the rotation shaft 54 is the other than the one wall portion 23c. It is housed inside the housing 11 in a state of approaching the wall portion 23d. The reduction mechanism 13 includes a worm 71 provided coaxially with the rotation shaft 54 and a first reduction gear 72 that meshes with the worm 71. The first reduction gear 72 is arranged between the rotating shaft 54 and one wall portion 23c. Therefore, even if the space between the pair of wall portions 23c and 23d is not widened, the space between the portion on the tip end side of the rotating shaft 54 and one wall portion 23c can be widened. Then, by arranging the first reduction gear 72 in the space between the portion on the tip end side of the rotating shaft 54 and the one wall portion 23c, the rotating axis L1 of the rotating shaft 54 is parallel to the longitudinal direction of the housing. As compared with the case where the motor 12 is housed in the housing, the actuator 10 can be miniaturized in a direction orthogonal to the longitudinal direction of the housing 11, that is, in a direction in which the pair of wall portions 23c and 23d face each other.

（４）給電装置１４は、第１及び第２接点端子部１０１，１２１、第１及び第２給電端子部１０２，１２２及び第１及び第２配線部１０３，１２３を保持する保持部材８７を有する。従って、第１配線部１０３及び第２配線部１２３への雑防素子８３，８５，８６の電気的な接続を容易に行うことができる。また、第１及び第２接点端子部１０１，１２１と接点部６１，６２との電気的な接続を容易に行うことができる。 (4) The power feeding device 14 has a holding member 87 for holding the first and second contact terminal portions 101, 121, the first and second feeding terminal portions 102, 122, and the first and second wiring portions 103, 123. .. Therefore, the miscellaneous protection elements 83, 85, and 86 can be easily electrically connected to the first wiring unit 103 and the second wiring unit 123. Further, the first and second contact terminal portions 101 and 121 can be easily electrically connected to the contact portions 61 and 62.

（５）給電ブラシを備えたモータ１２では、給電ブラシと整流子とが摺動する部分においてノイズが発生しやすい。当該ノイズを吸収するためには、チョークコイルである雑防素子８３，８５は、できるだけ接点部６１，６２に近い位置に設けられることが好ましい。本実施形態のアクチュエータ１０は、ヨーク５１における回転軸５４の基端側の端面とコネクタ部４１とが隣接しているためにヨーク５１における回転軸５４の基端側の端面とコネクタ部４１との間に雑防素子８３，８５，８６を配置するスペースが無い構成である。しかしながら、筐体１１の内部に上記した給電装置１４を収容することにより、筐体１１の内部で、第１及び第２給電端子部１０２，１２２と接点部６１，６２との間に雑防素子８３，８５を接続している。従って、給電ブラシと整流子とが摺動する部分で発生するノイズの影響を低減しやすい。 (5) In the motor 12 provided with the feeding brush, noise is likely to occur in the portion where the feeding brush and the commutator slide. In order to absorb the noise, it is preferable that the miscellaneous protection elements 83 and 85, which are choke coils, are provided at positions as close as possible to the contact portions 61 and 62. In the actuator 10 of the present embodiment, since the end surface on the proximal end side of the rotary shaft 54 in the yoke 51 and the connector portion 41 are adjacent to each other, the end surface on the proximal end side of the rotary shaft 54 in the yoke 51 and the connector portion 41 There is no space for arranging the miscellaneous protection elements 83, 85, 86 in between. However, by accommodating the above-mentioned power feeding device 14 inside the housing 11, a miscellaneous protection element is provided between the first and second power feeding terminal portions 102 and 122 and the contact portions 61 and 62 inside the housing 11. 83 and 85 are connected. Therefore, it is easy to reduce the influence of noise generated in the portion where the feeding brush and the commutator slide.

May be good.

・保持部材８７の形状は上記実施形態の形状に限らない。例えば、保持部材８７は、位置決め壁８７ｆを備えない構成であってもよい。また、給電装置１４は、必ずしも保持部材８７を備えなくてもよい。 The shape of the holding member 87 is not limited to the shape of the above embodiment. For example, the holding member 87 may be configured not to include the positioning wall 87f. Further, the power feeding device 14 does not necessarily have to include the holding member 87.

・上記実施形態では、第１減速ギヤ７２は、回転軸５４の先端側の部分と壁部２３ｃとの間に配置されている。しかしながら、筐体１１の内部における第１減速ギヤ７２の配置位置はこれに限らない。第１減速ギヤ７２は、筐体１１の内部でウォーム７１と噛合可能な位置に配置されればよい。例えば、第１減速ギヤ７２は、回転軸５４の先端側の部分と壁部２３ｄとの間に配置されてもよい。 In the above embodiment, the first reduction gear 72 is arranged between the tip end side portion of the rotary shaft 54 and the wall portion 23c. However, the arrangement position of the first reduction gear 72 inside the housing 11 is not limited to this. The first reduction gear 72 may be arranged at a position inside the housing 11 so as to be able to mesh with the worm 71. For example, the first reduction gear 72 may be arranged between the tip end side portion of the rotating shaft 54 and the wall portion 23d.

・上記実施形態では、減速機構１３は、第１～第４減速ギヤ７２～７５の４つの減速ギヤを有する。しかしながら、減速機構１３に備えられる減速ギヤの数はこれに限らず、１つ以上であればよい。また、減速機構１３は、必ずしもウォーム７１を備えなくてもよい。減速機構１３は、ウォーム７１に代えて、回転軸５４と一体回転する平歯車、はすば歯車、かさ歯車等の歯車を有する構成であってもよい。 In the above embodiment, the reduction mechanism 13 has four reduction gears, that is, first to fourth reduction gears 72 to 75.

It is housed inside the housing 11 in a state of being closer to the other wall portion 23d than the portion 23c. However, the arrangement mode of the motor 12 inside the housing 11 is not limited to this. For example, the motor 12 may be housed in the housing 11 so that the rotation axis L1 of the rotation shaft 54 is parallel to the longitudinal direction of the housing 11 between the pair of wall portions 23c and 23d. Further, for example, in the motor 12, the tip of the rotating shaft 54 is more wall than the wall portion 23d because the rotating axis L1 of the rotating shaft 54 is inclined with respect to the longitudinal direction of the housing 11 between the pair of wall portions 23c and 23d. It may be housed inside the housing 11 in a state of approaching the portion 23c. In this case, if the first reduction gear 72 is arranged between the rotating shaft 54 and the wall portion 23d, the same effect as in (3) of the above embodiment can be obtained.
