　受電コネクタから充電コネクタが外れるのを防ぐためのロック機構としては、充電コネクタに設けられたフックと、受電コネクタに設けられた係合突起と、受電コネクタの周囲に設けられたアクチュエータと、を備えているものがある（例えば、特許文献１参照）。 As a lock mechanism for preventing the charging connector from coming off from the power receiving connector, a hook provided on the charging connector, an engagement protrusion provided on the power receiving connector, and an actuator provided around the power receiving connector are provided. (For example, refer to Patent Document 1).

　前記したアクチュエータのハウジングには、モータ、電子部品、複数のギヤ、ロックピン等の部品が収容されている。このようなアクチュエータにおいては、モータの駆動に伴って各ギヤが浮き上がるのを防ぐために、ハウジングの内部に板状のプレートインナーを設置することが望ましい。この場合、例えば、ハウジングに対してプレートインナーをネジで固定することが考えられるが、ネジやボス穴を数多く設けるとハウジングの大型化や部品点数の増加を招来するという問題がある。また、プレートインナーとハウジングとのネジ留め箇所が増加すると、組み付け時の作業手間が増えるという問題がある。 The actuator housing contains components such as a motor, electronic components, a plurality of gears, and a lock pin. In such an actuator, it is desirable to install a plate-like plate inner inside the housing in order to prevent the gears from floating as the motor is driven. In this case, for example, it is conceivable to fix the plate inner to the housing with screws. However, if a large number of screws and boss holes are provided, there is a problem that the size of the housing increases and the number of parts increases. Moreover, when the screwing location of a plate inner and a housing increases, there exists a problem that the work effort at the time of an assembly increases.
　このような観点から本発明は、ハウジングの小型化や部品点数の削減を図るとともに、組み付けの時の作業手間を少なくすることができるアクチュエータを提供することを課題とする。 From such a viewpoint, an object of the present invention is to provide an actuator that can reduce the size of the housing and reduce the number of parts, and can reduce the labor for assembling.
　前記課題を解決するため、本発明は、複数の部品を収容するハウジングと、前記ハウジングに対して前記各部品を固定するプレートインナーと、モータの駆動により軸方向に往復動するロックピンと、を含むアクチュエータである。前記ハウジングおよび前記プレートインナーは、前記ロックピンが挿通される挿通孔をそれぞれ有することを特徴とする。 In order to solve the above-described problems, the present invention includes a housing that accommodates a plurality of components, a plate inner that fixes the components to the housing, and a lock pin that reciprocates in the axial direction by driving a motor. Actuator. The housing and the plate inner have insertion holes through which the lock pins are inserted, respectively.
　かかる構成によれば、ロックピンが各挿通孔を通ることによってハウジングに対するプレートインナーの浮き上がりが阻止される。これにより、プレートインナーを固定するためのボス穴やネジの本数を減らすことができるため、ハウジングの小型化および部品点数の削減を図ることができる。また、ネジ留めの本数を減らせるため、組み付け時の作業手間を少なくすることができる。 According to such a configuration, the plate inner is prevented from floating with respect to the housing when the lock pin passes through each insertion hole. Thereby, since the number of boss holes and screws for fixing the plate inner can be reduced, the housing can be downsized and the number of parts can be reduced. In addition, since the number of screwing can be reduced, the labor for assembling can be reduced.
　また、前記プレートインナーの挿通孔の断面形状は、前記ロックピンの断面形状とは異なる形状であり、当該挿通孔の孔壁と前記ロックピンとが点接触又は線接触することが好ましい。また、前記プレートインナーの挿通孔の断面形状は多角形であり、前記挿通孔の孔壁と前記ロックピンとが点接触又は線接触することが好ましい。また、前記プレートインナーの挿通孔の孔壁には、前記ロックピンと点接触又は線接触する突起が設けられていることが好ましい。 The cross-sectional shape of the insertion hole of the plate inner is different from the cross-sectional shape of the lock pin, and it is preferable that the hole wall of the insertion hole and the lock pin are in point contact or line contact. Moreover, it is preferable that the cross-sectional shape of the insertion hole of the said plate inner is a polygon, and the hole wall of the said insertion hole and the said lock pin make a point contact or a line contact. Moreover, it is preferable that the hole wall of the insertion hole of the inner plate is provided with a protrusion that makes point contact or line contact with the lock pin.
　かかる構成によれば、ロックピンとプレートインナーとの摩擦を軽減できる。 According to such a configuration, friction between the lock pin and the plate inner can be reduced.
　また、前記プレートインナーの挿通孔は、前記ハウジングの内部に向かうにつれて断面積が小さくなることが好ましい。かかる構成によれば、プレートインナーの挿通孔にロックピンを挿入しやすくなるため、組付け性が向上する。 Also, it is preferable that the insertion hole of the plate inner has a cross-sectional area that decreases toward the inside of the housing. According to such a configuration, the lock pin can be easily inserted into the insertion hole of the inner plate, so that the assembling property is improved.
　また、前記プレートインナーには、前記挿通孔を備えた抑え部が設けられており、前記ロックピンには、シール部材が配置されており、前記シール部材は、前記抑え部と前記ハウジングとの間に配置されていることが好ましい。 The plate inner is provided with a holding portion having the insertion hole, and a seal member is disposed on the lock pin, and the seal member is disposed between the holding portion and the housing. It is preferable to arrange | position.
　かかる構成によれば、ハウジングの防水性を向上させることができる。また、シール部材がハウジングと抑え部との間に配置されているため、ハウジングの外部からロックピンを挿入した際に、ロックピンの挿入に伴うシール部材の移動が抑え部によって阻止される。これにより、ロックピンの組付け性を向上させることができる。 According to such a configuration, the waterproofness of the housing can be improved. Further, since the seal member is disposed between the housing and the holding portion, when the lock pin is inserted from the outside of the housing, the movement of the seal member accompanying insertion of the lock pin is prevented by the holding portion. Thereby, the assembly | attachment property of a lock pin can be improved.
　本発明のアクチュエータでは、ハウジングの小型化や部品点数の削減を図るとともに、組み付け時の作業手間を少なくすることができる。 In the actuator of the present invention, the housing can be reduced in size and the number of parts can be reduced, and the labor for assembling can be reduced.

The lock mechanism 5 prevents the charging connector 4 from being detached from the power receiving connector 3 when charging a storage battery (not shown) mounted on the vehicle 1.
In the following description, “upper and lower”, “front and rear”, and “left and right” are set for convenience in describing the structure of the actuator 10, and do not limit the orientation of the actuator 10.
　車体２の充電口２ａは、受電コネクタ３の先端部が収容されている空間である。充電口２ａの壁部２ｂの開口部には、受電コネクタ３が挿通されており、受電コネクタ３の先端部が充電口２ａ内に突出している。受電コネクタ３は、ケーブル（図示せず）を介して蓄電池（図示せず）に電気的に接続されている。なお、受電コネクタ３は、先端側から車内側に向かうに従って下がるように、水平面に対して軸線が３０度傾斜している。 The charging port 2a of the vehicle body 2 is a space in which the leading end of the power receiving connector 3 is accommodated. The power receiving connector 3 is inserted through the opening of the wall 2b of the charging port 2a, and the tip of the power receiving connector 3 projects into the charging port 2a. The power receiving connector 3 is electrically connected to a storage battery (not shown) via a cable (not shown). The power receiving connector 3 has an axis inclined at 30 degrees with respect to a horizontal plane so that the power receiving connector 3 is lowered from the front end side toward the vehicle interior side.

　図４（ａ）に示すように、下部ギヤ９２は電動モータ８０のねじ歯車８１ａに連結され、上部ギヤ９３はカムギヤ７２に連結される。 The drive transmission member 90 is a rotating shaft 91 whose axial direction is arranged in the vertical direction, a lower gear 92 that is a helical gear having the rotating shaft 91 as a central axis, and a spur gear that has the rotating shaft 91 as a central axis. And an upper gear 93.
The upper and lower ends of the rotation shaft 91 are rotatably supported by the lower surface of the housing upper 40 and the bottom surface 33a of the housing lower 30.
As shown in FIG. 4A, the lower gear 92 is connected to the screw gear 81 a of the electric motor 80, and the upper gear 93 is connected to the cam gear 72.
　電動モータ８０のねじ歯車８１ａを回転させると、その駆動力が下部ギヤ９２に伝達され、駆動伝達部材９０が軸回りに回転する。これにより、上部ギヤ９３からカムギヤ７２に駆動力が伝達され、カムギヤ７２が軸回りに回転することで、カム７３が回転軸７１の軸回りに回転するように構成されている。 When the screw gear 81a of the electric motor 80 is rotated, the driving force is transmitted to the lower gear 92, and the drive transmission member 90 rotates about the axis. As a result, the driving force is transmitted from the upper gear 93 to the cam gear 72, and the cam 73 rotates around the axis, whereby the cam 73 rotates around the axis of the rotating shaft 71.
　ホルダ６０は、ハウジングロア３０の底面３３ａ上に前後方向に移動自在に取り付けられている。ホルダ６０のピン保持部６１にロックピン５０の後部が取り付けられ、ホルダ６０の後部にはカム７３が収容されるカム収容枠６２が開口している。カム収容枠６２は、上下方向に開口しており、上側からカム７３が挿入される。カム収容枠６２の内周面は、カム７３が当接するカム受け面となっている。また、ホルダ６０の前部には、右側に向けて突出したロッド６３が形成されている。ロッド６３は後記する退行側のスイッチ１１０（図３参照）の検出部を押し込む部位である。 The holder 60 is mounted on the bottom surface 33a of the housing lower 30 so as to be movable in the front-rear direction.

The cam housing frame 62 opens in the vertical direction, and the cam 73 is inserted from above. The inner peripheral surface of the cam housing frame 62 is a cam receiving surface with which the cam 73 abuts.

A fitting portion 66 to be fitted is formed. The through hole 64 is a hole penetrating in the front-rear direction, and has a substantially triangular cross section in the present embodiment (see FIG. 6B). The outer peripheral surface of the lock pin 50 comes into contact with three inner surfaces (planes) constituting the hole wall of the through hole 64. A round chamfering process is applied to the front corner of the through hole 64. This makes it easy to insert the lock pin 50 into the through hole 64.
　図５（ｂ）に示すように、係合部６５の基端部６５ｂがピン保持部６１に連続しており、係合部６５の先端部が自由端になっている。係合部６５は、ピン保持部６１に片持ち支持されており、図５（ｂ）において上下方向に弾性変形可能になっている。係合部６５の先端側には、下方に突出する爪部６５ａが形成されている。爪部６５ａは、ロックピン５０の凹部５０ａに係合する部位である。 As shown in FIG. 5B, the base end portion 65b of the engaging portion 65 is continuous with the pin holding portion 61, and the distal end portion of the engaging portion 65 is a free end.

The fitting portion 66 is formed with a contact surface 66a with which the rear end surface of the lock pin 50 contacts. Further, as shown in FIG. 6C, the outer peripheral surface of the lock pin 50 comes into contact with three inner surfaces (planes) constituting the hole wall of the fitting portion 66.
　基板１００は、図３に示すように、左右方向に幅広に形成され、電動モータ８０およびホルダ６０の上方に配置される。
　基板１００は、電動モータ８０の駆動を制御するものであり、電動モータ８０、スイッチ１１０および雄コネクタ３５が電気的に接続されている。 As shown in FIG. 3, the substrate 100 is formed wide in the left-right direction, and is disposed above the electric motor 80 and the holder 60.

　スイッチ１１０は、基板１００の下面に取り付けられている。本実施形態では、二つのスイッチ１１０が左右方向に並設され、カムギヤ７２のロッド７２ａおよびホルダ６０のロッド６３の移動領域の上方にそれぞれ配置される。 The switch 110 is attached to the lower surface of the substrate 100. In the present embodiment, the two switches 110 are juxtaposed in the left-right direction and are respectively disposed above the moving regions of the rod 72 a of the cam gear 72 and the rod 63 of the holder 60.
　図３に示すように、プレートインナー１２０は、カム部材７０と基板１００との間に配設される。プレートインナー１２０は、ハウジング２０の内部に収容されるホルダ６０、カム部材７０、電動モータ８０および駆動伝達部材９０等の各部品をハウジングロア３０に固定するための板状部材である。 As shown in FIG. 3, the plate inner 120 is disposed between the cam member 70 and the substrate 100. The plate inner 120 is a plate-like member for fixing each component such as the holder 60, the cam member 70, the electric motor 80, and the drive transmission member 90 accommodated in the housing 20 to the housing lower 30.
　プレートインナー１２０は、本体板部１２１と、カム収容部１２２と、抑え部１２３とを含んで構成されている。本体板部１２１は、電動モータ８０および駆動伝達部材９０の上部を覆うように形成されている。また、本体板部１２１には、補強のためのリブが立設されている。カム収容部１２２は、カム部材７０を収容するための部位である。カム収容部１２２は、平面視円形状を呈し、上方に突出している。 The plate inner 120 includes a main body plate part 121, a cam housing part 122, and a holding part 123.

　抑え部１２３は、シール部材Ｓ１を抑えるとともに、ロックピン５０を固定するための部位である。抑え部１２３は、板状を呈し、本体板部１２１の前側において本体板部１２１から垂下している。抑え部１２３には第二挿通孔１２４が形成されている。第二挿通孔１２４は、抑え部１２３の下部を前後方向に貫通している。第二挿通孔１２４には、ロックピン５０が挿通される。図７に示すように、抑え部１２３は、周壁部３４に接している。シール部材Ｓ１は、周壁部３４と抑え部１２３との間に配置される。 The holding portion 123 is a portion for holding the lock pin 50 while holding down the seal member S1. The holding portion 123 has a plate shape and hangs down from the main body plate portion 121 on the front side of the main body plate portion 121. A second insertion hole 124 is formed in the holding portion 123. The second insertion hole 124 penetrates the lower portion of the holding portion 123 in the front-rear direction. The lock pin 50 is inserted into the second insertion hole 124. As shown in FIG. 7, the holding portion 123 is in contact with the peripheral wall portion 34.

　抑え部１２３の後面には、抑え部１２３と本体板部１２１とを連結する板状のリブ１２５が形成されている。リブ１２５を設けることで、抑え部１２３の強度を向上させることができる。第二挿通孔１２４の前側の角部には、丸面取り加工が施されている。 A plate-like rib 125 that connects the holding portion 123 and the main body plate portion 121 is formed on the rear surface of the holding portion 123. By providing the rib 125, the strength of the restraining portion 123 can be improved. A round chamfering process is performed on the front corner of the second insertion hole 124.
　図８に示すように、第二挿通孔１２４を構成する孔壁は、水平な底面１２４ａと、底面１２４ａに対して垂直な側面１２４ｂ，１２４ｂと、上面１２４ｃとで構成されている。上面１２４ｃは、ロックピン５０の形状に沿って円弧状になっている。第二挿通孔１２４の孔壁とロックピン５０とは接触するか又は微細な隙間をあけて配設される。 As shown in FIG. 8, the hole wall constituting the second insertion hole 124 includes a horizontal bottom surface 124a, side surfaces 124b and 124b perpendicular to the bottom surface 124a, and a top surface 124c. The upper surface 124 c has an arc shape along the shape of the lock pin 50. The hole wall of the second insertion hole 124 and the lock pin 50 are in contact with each other or arranged with a fine gap.
　次に、図３等を参照してハウジング２０の組付け方法について説明する。まず、ハウジングロア３０の周壁部３４の前側に設けられた凹部３４ａ（図４（ｂ）参照）に、シール部材Ｓ１を配置する。そして、ハウジングロア３０に、ホルダ６０、カム部材７０、電動モータ８０、駆動伝達部材９０、プレートインナー１２０、スイッチ１１０を備えた基板１００を組み付ける。そして、ネジＮ１，Ｎ２をボス穴Ｍ１，Ｍ２に締結してハウジングロア３０にプレートインナー１２０を固定する。また、ネジＮ３をボス穴Ｍ３に締結してハウジングロア３０に基板１００およびプレートインナー１２０を固定する。 Next, a method for assembling the housing 20 will be described with reference to FIG. First, the seal member S <b> 1 is disposed in the recess 34 a (see FIG. 4B) provided on the front side of the peripheral wall portion 34 of the housing lower 30. And the board | substrate 100 provided with the holder 60, the cam member 70, the electric motor 80, the drive transmission member 90, the plate inner 120, and the switch 110 to the housing lower 30 is assembled | attached. Then, the screws N1 and N2 are fastened to the boss holes M1 and M2 to fix the plate inner 120 to the housing lower 30. The board N and the plate inner 120 are fixed to the housing lower 30 by fastening the screw N3 to the boss hole M3.
　そして、ハウジングロア３０の開口縁部３７にシール部材（図示せず）を配置しつつ、ハウジングロア３０にハウジングアッパー４０を取り付ける。そして、ハウジングアッパー４０の上にロック解除用レバー４２を配置して、ロック解除用レバー４２と回転軸７１とをネジＮ４で締結する。 Then, the housing upper 40 is attached to the housing lower 30 while a seal member (not shown) is disposed on the opening edge 37 of the housing lower 30. Then, the unlocking lever 42 is disposed on the housing upper 40, and the unlocking lever 42 and the rotating shaft 71 are fastened with the screw N4.
　最後に、ロックピン５０を第一挿通孔３８から挿入してホルダ６０に固定する。具体的には、図７に示すように、ロックピン５０をシール部材Ｓ１、第二挿通孔１２４および貫通孔６４に挿入しつつ嵌合部６６まで押し込む。ロックピン５０がホルダ６０内に挿入されると、ロックピン５０の外周面が係合部６５の先端側を上方に押し上げる。さらにロックピン５０を進入させると、ロックピン５０の後端面が嵌合部６６の当接面６６ａに当接するとともに係合部６５が元の形状に復元する。これにより、爪部６５ａが凹部５０ａに入り込んでロックピン５０と係合部６５とが係合し、ロックピン５０がホルダ６０に対して移動不能に拘束される。また、貫通孔６４および嵌合部６６の孔壁を構成する３つの内面とロックピン５０の外周面とが接触するため、ロックピン５０の後端側はホルダ６０に強固に固定される。 Finally, the lock pin 50 is inserted from the first insertion hole 38 and fixed to the holder 60. Specifically, as shown in FIG. 7, the lock pin 50 is pushed into the fitting portion 66 while being inserted into the seal member S <b> 1, the second insertion hole 124 and the through hole 64. When the lock pin 50 is inserted into the holder 60, the outer peripheral surface of the lock pin 50 pushes the distal end side of the engaging portion 65 upward. When the lock pin 50 is further advanced, the rear end surface of the lock pin 50 comes into contact with the contact surface 66a of the fitting portion 66 and the engagement portion 65 is restored to its original shape. As a result, the claw portion 65 a enters the recess 50 a and the lock pin 50 and the engagement portion 65 are engaged, and the lock pin 50 is restrained against movement with respect to the holder 60. Further, since the three inner surfaces constituting the hole walls of the through hole 64 and the fitting portion 66 come into contact with the outer peripheral surface of the lock pin 50, the rear end side of the lock pin 50 is firmly fixed to the holder 60.
　本実施形態のアクチュエータ１０では、図４（ａ）に示すように、電動モータ８０のねじ歯車８１ａが回転すると、その駆動力が駆動伝達部材９０を介してカムギヤ７２に伝達される。そして、カムギヤ７２が回転することで、カム７３が前方または後方に向けて回転移動し、カム７３によってカム収容枠６２の内周面が前方または後方に押し出される。これにより、ホルダ６０およびロックピン５０が前方または後方に移動し、ハウジング２０に対するロックピン５０の突出量が増減する。 In the actuator 10 of the present embodiment, as shown in FIG. 4A, when the screw gear 81a of the electric motor 80 rotates, the driving force is transmitted to the cam gear 72 via the drive transmission member 90. Then, as the cam gear 72 rotates, the cam 73 rotates and moves forward or backward, and the cam 73 pushes the inner peripheral surface of the cam housing frame 62 forward or backward. As a result, the holder 60 and the lock pin 50 move forward or backward, and the amount of protrusion of the lock pin 50 relative to the housing 20 increases or decreases.
　ホルダ６０が前方に移動したときに、カムギヤ７２のロッド７２ａによって進出側のスイッチ１１０（図３参照）の検出部が押し込まれると、進出側のスイッチ１１０から制御装置（図示せず）に検出信号が出力され、出力軸８１の回転が停止する。
　また、ホルダ６０が後方に移動したときに、ホルダ６０のロッド６３によって退行側のスイッチ１１０（図３参照）の検出部が押し込まれると、退行側のスイッチ１１０から制御装置に検出信号が出力され、出力軸８１の回転が停止する。 When the holder 60 moves forward and the detecting portion of the advance switch 110 (see FIG. 3) is pushed in by the rod 72a of the cam gear 72, a detection signal is sent from the advance switch 110 to a control device (not shown). Is output, and the rotation of the output shaft 81 stops.
Further, when the detection unit of the retreat-side switch 110 (see FIG. 3) is pushed by the rod 63 of the holder 60 when the holder 60 moves rearward, a detection signal is output from the retreat-side switch 110 to the control device. Then, the rotation of the output shaft 81 stops.
　図１に示すように、受電コネクタ３に充電コネクタ４が装着されたことを制御装置（図示せず）が検出した場合には、ロックピン５０がハウジング２０に対して進出し、ロックピン５０の前部が充電コネクタ４のフック４ｂの上方に配置される。
　これにより、フック４ｂの傾動がロックピン５０によって規制され、フック４ｂは受電コネクタ３の係合突起３ｂに係合した状態に固定されるため、受電コネクタ３から充電コネクタ４が外れるのを防ぐことができる。
　そして、ロックピン５０の進出が停止した後に、充電装置（図示せず）から蓄電池（図示せず）への充電が開始される。 As shown in FIG. 1, when a control device (not shown) detects that the charging connector 4 is attached to the power receiving connector 3, the lock pin 50 moves into the housing 20, and the lock pin 50 The front portion is disposed above the hook 4 b of the charging connector 4.
As a result, the tilt of the hook 4b is regulated by the lock pin 50, and the hook 4b is fixed in a state of being engaged with the engagement protrusion 3b of the power receiving connector 3, thereby preventing the charging connector 4 from being detached from the power receiving connector 3. Can do.
Then, after the advancement of the lock pin 50 is stopped, charging from the charging device (not shown) to the storage battery (not shown) is started.
　また、充電後にロック解除信号が制御装置（図示せず）に入力されると、ロックピン５０がハウジング２０に対して退行し、ロックピン５０の前部が充電コネクタ４のフック４ｂの上方から退去する。
　これにより、フック４ｂが傾動可能となり、フック４ｂを受電コネクタ３の係合突起３ｂから離脱させて、受電コネクタ３から充電コネクタ４を引き抜くことができる。 When a lock release signal is input to the control device (not shown) after charging, the lock pin 50 retreats with respect to the housing 20, and the front portion of the lock pin 50 retreats from above the hook 4 b of the charging connector 4. To do.
As a result, the hook 4 b can be tilted, the hook 4 b can be detached from the engagement protrusion 3 b of the power receiving connector 3, and the charging connector 4 can be pulled out from the power receiving connector 3.
　また、図３に示すように、ハウジングアッパー４０の上面には、カム部材７０の回転軸７１の上端部に取り付けられたロック解除用レバー４２が設けられている（図２参照）。ロック解除用レバー４２を回転させることで、カム部材７０を手動で強制的に回転させ、ロックピン５０を退行させることができる。 Further, as shown in FIG. 3, on the upper surface of the housing upper 40, an unlocking lever 42 attached to the upper end portion of the rotating shaft 71 of the cam member 70 is provided (see FIG. 2). By rotating the unlocking lever 42, the cam member 70 can be forcibly rotated manually and the lock pin 50 can be retracted.
　また、図８に示すように、ロックピン５０が進出又は退行している時、つまり、電動モータ８０の回転力が各ギヤに伝達される際、はすば歯車である下部ギヤ９２から受ける荷重によってプレートインナー１２０は上向き及び横向きの力を受ける。このため、ハウジングロア３０に対してプレートインナー１２０がわずかに浮き上がったり、左右方向にわずかに移動する。この際、ロックピン５０は、第二挿通孔１２４の孔壁のうち底面１２４ａおよび側面１２４ｂの少なくとも一方と接触する。一方、ロックピン５０が停止している時、つまり、電動モータ８０が停止している時は第二挿通孔１２４の孔壁とロックピン５０とは接触するか、わずかな隙間をあけて配設されている。 Further, as shown in FIG. 8, when the lock pin 50 is advanced or retracted, that is, when the rotational force of the electric motor 80 is transmitted to each gear, the load received from the lower gear 92 that is a helical gear. Accordingly, the plate inner 120 receives an upward force and a lateral force. For this reason, the plate inner 120 slightly floats with respect to the housing lower 30 or moves slightly in the left-right direction. At this time, the lock pin 50 contacts at least one of the bottom surface 124 a and the side surface 124 b of the hole wall of the second insertion hole 124. On the other hand, when the lock pin 50 is stopped, that is, when the electric motor 80 is stopped, the hole wall of the second insertion hole 124 and the lock pin 50 are in contact with each other or disposed with a slight gap. Has been.
　以上のようなアクチュエータ１０では、ロックピン５０の後端側がホルダ６０に固定されるとともに第一挿通孔３８および第二挿通孔１２４にロックピン５０が挿通されることにより、ハウジング２０に対してプレートインナー１２０の浮き上がりが阻止される。これにより、プレートインナー１２０を固定するためのボス穴やネジの本数を減らすことができるため、ハウジングの小型化および部品点数の削減を図ることができる。 In the actuator 10 as described above, the rear end side of the lock pin 50 is fixed to the holder 60 and the lock pin 50 is inserted into the first insertion hole 38 and the second insertion hole 124, so that the plate is inserted into the housing 20. The inner 120 is prevented from lifting. Thereby, since the number of boss holes and screws for fixing the plate inner 120 can be reduced, the housing can be downsized and the number of parts can be reduced.
　詳述すると、図４の（ａ）に示すように、プレートインナー１２０の浮き上がりをバランスよく抑えるためには、望ましくはハウジングロア３０の前側縁部であって、ロックピン５０を挟んでボス穴Ｍ３と反対側の位置にもボス穴を設けてネジで締結する必要がある。しかし、当該位置にボス穴を設けると、このボス穴とホルダ６０（ロッド６３）の可動領域とが干渉するため、ハウジング２０を大きくせざるを得ない。これに対し、本実施形態では、当該位置にボス穴を設けることに替えて、第一挿通孔３８および第二挿通孔１２４でプレートインナー１２０の前側の浮き上がりを抑えることにしたため、ハウジング２０の小型化を図ることができる。第一挿通孔３８及び第二挿通孔１２４は、図４（ａ）に示すボス穴Ｍ１～Ｍ３を頂点とする三角形の外側であり、かつ、周壁部３４の前側に配置されていることが望ましい。 More specifically, as shown in FIG. 4A, in order to suppress the floating of the plate inner 120 in a well-balanced manner, the boss hole M3 is preferably a front edge of the housing lower 30 with the lock pin 50 interposed therebetween. It is necessary to provide a boss hole on the opposite side of the screw and fasten with screws. However, if a boss hole is provided at this position, the boss hole interferes with the movable region of the holder 60 (rod 63), so the housing 20 must be enlarged. On the other hand, in this embodiment, instead of providing the boss hole at the position, the first insertion hole 38 and the second insertion hole 124 prevent the front inner plate 120 from being lifted. Can be achieved. The first insertion hole 38 and the second insertion hole 124 are preferably arranged outside the triangle having the boss holes M1 to M3 shown in FIG. 4A as vertices and on the front side of the peripheral wall portion 34. .
　また、ロックピン５０が進出又は退行する際、第二挿通孔１２４の孔壁とロックピン５０とが線接触又は点接触する。これにより、ロックピン５０と第二挿通孔１２４との摩擦が小さくなるため、ロックピン５０の作動性が向上する。 Also, when the lock pin 50 advances or retreats, the hole wall of the second insertion hole 124 and the lock pin 50 are in line contact or point contact. Thereby, since the friction between the lock pin 50 and the second insertion hole 124 is reduced, the operability of the lock pin 50 is improved.
　また、本実施形態では、電動モータ８０の駆動中に、プレートインナー１２０がハウジングロア３０に対して下方に移動する可能性は低いため、第二挿通孔１２４の上面１２４ｃ（図８参照）をロックピン５０の形状に沿って円弧状に形成している。これにより、抑え部１２３の開口を極力小さくできるため、抑え部１２３の強度を大きくすることができる。 In the present embodiment, the plate inner 120 is unlikely to move downward relative to the housing lower 30 while the electric motor 80 is being driven, so the upper surface 124c (see FIG. 8) of the second insertion hole 124 is locked. An arc shape is formed along the shape of the pin 50. Thereby, since the opening of the suppressing part 123 can be made as small as possible, the strength of the suppressing part 123 can be increased.
　ここで、従来は、アクチュエータ１０を組み付ける際に、一体化したロックピン５０およびホルダ６０をハウジングロア３０に組み付けた後、ハウジングロア３０にハウジングアッパー４０を固定していた。しかし、このような組み付け方法であると、一体化したロックピン５０およびホルダ６０をハウジングロア３０に組み付ける際に、ハウジングロア３０の後側に、組み付けるための逃げスペースを設けなければならないため、ハウジング２０の大型化を招来していた。しかし、本実施形態のように、ハウジングロア３０とハウジングアッパー４０とを組み付けた後に、ロックピン５０をハウジング２０の外側から挿入することで、ハウジングロア３０に逃げスペースを設ける必要がなくなる。このように、組み付けの観点からもハウジング２０の小型化を図ることができる。 Here, conventionally, when the actuator 10 is assembled, the integrated lock pin 50 and the holder 60 are assembled to the housing lower 30, and then the housing upper 40 is fixed to the housing lower 30. However, with such an assembly method, when the integrated lock pin 50 and holder 60 are assembled to the housing lower 30, a clearance space for assembly must be provided on the rear side of the housing lower 30. Invited 20 enlargements. However, it is not necessary to provide a clearance space in the housing lower 30 by inserting the lock pin 50 from the outside of the housing 20 after assembling the housing lower 30 and the housing upper 40 as in this embodiment. Thus, the housing 20 can be downsized from the viewpoint of assembly.
　また、ハウジングロア３０とハウジングアッパー４０を組み付けた後に、ハウジング２０の外側からロックピン５０を第一挿通孔３８および第二挿通孔１２４に挿入するだけでよいため、組み付けの際の作業手間を少なくすることができる。また、第一挿入孔３８にはハウジング２０の内部に向けて断面積が小さくなるようにテーパーが設けられるとともに、第二挿通孔１２４の前側の角部には丸面取り加工が施されている。これにより、第一挿入孔３８および第二挿通孔１２４にロックピン５０を挿入しやすい。また、第一挿入孔３８にテーパーが設けられているため、第一挿入孔３８とロックピン５０との摺動抵抗を軽減することができる。 Further, after the housing lower 30 and the housing upper 40 are assembled, it is only necessary to insert the lock pin 50 into the first insertion hole 38 and the second insertion hole 124 from the outside of the housing 20, thereby reducing the labor for assembling. can do. Further, the first insertion hole 38 is tapered so that the cross-sectional area decreases toward the inside of the housing 20, and the front corner of the second insertion hole 124 is rounded. Thereby, it is easy to insert the lock pin 50 into the first insertion hole 38 and the second insertion hole 124. Further, since the first insertion hole 38 is tapered, the sliding resistance between the first insertion hole 38 and the lock pin 50 can be reduced.
　また、シール部材Ｓ１を設けることで、ハウジング２０の防水性を向上させることができる。また、抑え部１２３とハウジングロア３０とでシール部材Ｓ１を挟持するようにしたため、ハウジング２０の外部からロックピン５０を挿入する際に、ロックピン５０の挿入に伴うシール部材Ｓ１の移動が阻止される。これにより、組付け性を向上させることができる。 Moreover, the waterproofness of the housing 20 can be improved by providing the seal member S1. Further, since the seal member S1 is sandwiched between the holding portion 123 and the housing lower 30, when the lock pin 50 is inserted from the outside of the housing 20, the movement of the seal member S1 accompanying the insertion of the lock pin 50 is prevented. The Thereby, assembly property can be improved.
　以上、本発明の実施形態について説明したが、本発明は前記実施形態に限定されることなく、その趣旨を逸脱しない範囲で適宜に変更が可能である。例えば、第二挿通孔１２４の断面形状は、ロックピン５０の断面形状と相似であってもよいし、本実施形態のように異なる形状であってもよい。また、例えば、第二挿通孔１２４の断面を三角形、四角形等他の多角形状に形成し、ロックピン５０と点接触又は線接触するようにしてもよい。また、第二挿通孔１２４の孔壁から開口中央に向けて突出する単一又は複数の突起を設けて、ロックピン５０と点接触又は線接触するようにしてもよい。このような構成としても、ロックピン５０と第二挿通孔１２４との摩擦を軽減できる。線接触させる場合には、ロックピン５０の軸方向に沿って接触させるように設定することが望しい。また、第二挿通孔１２４を、ハウジングロア３０の内側に向かうにつれて断面積が小さくなるように形成してもよい。このように形成することで、第二挿通孔１２４にロックピン５０を挿入しやすくなるとともに、ロックピン５０と第二挿通孔１２４との摩擦を低減することができる。 As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment, In the range which does not deviate from the meaning, it can change suitably. For example, the cross-sectional shape of the second insertion hole 124 may be similar to the cross-sectional shape of the lock pin 50, or may be a different shape as in this embodiment. Further, for example, the cross section of the second insertion hole 124 may be formed in another polygonal shape such as a triangle, a quadrangle, and the lock pin 50 may be in point contact or line contact. Further, a single or a plurality of protrusions protruding from the hole wall of the second insertion hole 124 toward the center of the opening may be provided so as to make point contact or line contact with the lock pin 50. Even with such a configuration, friction between the lock pin 50 and the second insertion hole 124 can be reduced. In the case of line contact, it is desirable to set so as to make contact along the axial direction of the lock pin 50. Further, the second insertion hole 124 may be formed so that the cross-sectional area becomes smaller toward the inside of the housing lower 30. By forming in this way, it becomes easy to insert the lock pin 50 into the second insertion hole 124, and friction between the lock pin 50 and the second insertion hole 124 can be reduced.
　なお、本実施形態では、貫通孔６４および嵌合部６６の断面を略三角形状としたが、ロックピン５０を固定できる形状であれば、他の多角形状としてもよいし円形状としてもよい。また、貫通孔６４および嵌合部６６を構成する内面から突出する単一又は複数の突起を設けるようにしてもよい。 In addition, in this embodiment, although the cross section of the through-hole 64 and the fitting part 66 was made into the substantially triangular shape, if it is a shape which can fix the lock pin 50, it may be another polygonal shape or a circular shape. Moreover, you may make it provide the single or several protrusion which protrudes from the inner surface which comprises the through-hole 64 and the fitting part 66. FIG.
　また、本実施形態では、受電コネクタ３から充電コネクタ４が外れるのを防ぐためのロック機構５に、本発明のアクチュエータを適用しているが、本発明のアクチュエータは各種のアクチュエータに適用可能である。 Further, in the present embodiment, the actuator of the present invention is applied to the lock mechanism 5 for preventing the charging connector 4 from being detached from the power receiving connector 3, but the actuator of the present invention is applicable to various actuators. .
