Abstract

PROBLEM TO BE SOLVED: To provide a structure that the dislocation-preventing of a charging connector can be executed automatically when the charging connector is inserted into a charging port, and prevent charging in the state where the charging connector is detachable.SOLUTION: When a charging connector 2 moves from the right side in a figure to the right and is inserted into a charging port 7, and first, an insertion direction apical surface 2b of the charging connector 2 comes into contact with a leg part 11b of a charging connector dislocation-preventing member 11 as shown in (a). An insertion force of the charging connector 2 gives a rotation moment around a pivot pin 12 in which an off-set β is defined as an arm length, to a charging connector pressing leg part 11b from that time. The rotation moment makes the charging connector pressing leg part 11b slip on the insertion direction apical surface 2b of the charging connector 2 and while rotating and moving the charging pressing leg part 11b from a position (b) to a position (c) around the pivot pin 12. Thereby a lock pin 11a facing to the leg part 11b of the charging connector dislocation-preventing member 11 tucks to a lock pin 2a of the charging connector 2, and prevents the charging connector 2 from dislocating from the charging port 7.

Description

本発明は、車外充電器の充電コネクタを車載充電ポートに挿入した状態で車外充電器からの電力により車載バッテリを充電する際に用いる車両用外部充電器接続構造に関し、特に充電コネクタが充電中に充電ポートから外脱することのないようにする充電コネクタ外脱防止機構の改良提案に係わる。   The present invention relates to an external charger connection structure for a vehicle that is used when charging an in-vehicle battery with electric power from an out-of-vehicle charger with the charging connector of the in-vehicle charger inserted into the in-vehicle charging port, and in particular, the charging connector is being charged. The present invention relates to a proposal for improving a charging connector removal preventing mechanism that prevents the charging port from being detached.

充電中に充電コネクタが充電ポートから外脱することは、充電用の給電路が強電系であることともあって、好ましくない。
そこで、充電コネクタが充電中に充電ポートから外脱することのないようにする必要があり、そのための充電コネクタ外脱防止機構としては従来、例えば特許文献1に記載のごときものが知られている。 It is not preferable that the charging connector is detached from the charging port during charging because the charging power supply path is a strong electric system.
Therefore, it is necessary to prevent the charging connector from coming off from the charging port during charging, and as a charging connector removal preventing mechanism for that purpose, the one described in Patent Document 1, for example, has been conventionally known. .

この提案技術は、充電コネクタを充電ポートに挿入したバッテリ充電中、充電用の給電路に流れる電流を検出し、この電流検出に応答して電磁ソレノイドを作動させることにより、充電ポートに対する充電コネクタの挿脱方向を横切る方向へロックピンを進出させて、その先端部の係合作用により上記挿入状態の充電コネクタが充電ポートから外脱することのないようにしたものである。   This proposed technology detects the current flowing through the charging power supply path during battery charging with the charging connector inserted into the charging port, and operates the electromagnetic solenoid in response to this current detection, so that the charging connector for the charging port is The lock pin is advanced in a direction crossing the insertion / removal direction so that the charging connector in the inserted state does not come off from the charging port by the engaging action of the tip.

実開平０４−１２１６７３号公報Japanese Utility Model Publication No. 04-121673

しかし上記した型式の充電コネクタ外脱防止機構にあっては、電磁ソレノイドが作動不能になるなどにより、充電コネクタの外脱防止機能を司るロックピンの先端部が充電コネクタのロック孔内に陥入し得ず、充電コネクタの外脱防止を果たし得ない場合の対策が何ら施されていない。   However, in the above-described type of charging connector removal prevention mechanism, when the electromagnetic solenoid becomes inoperable, the tip of the lock pin that controls the removal function of the charging connector is inserted into the locking hole of the charging connector. However, no measures are taken when the charging connector cannot be prevented from coming off.

そのため、かかる充電コネクタの外脱防止不可状態であっても充電が行われ得ることとなる。
この充電中に、充電コネクタから外部充電器に至る電源コードに誤って足を引っかけるなどにより充電コネクタが充電ポートから引き抜かれる方向の外力を受けると、充電コネクタが充電ポートから外脱することがあり、当該充電中における充電コネクタの外脱は、充電用の給電路が強電系であることともあって好ましくない。 Therefore, charging can be performed even when the charging connector is in a state in which it cannot be removed.
During this charging, if the charging connector is pulled out of the charging port due to accidental catching on the power cord from the charging connector to the external charger, the charging connector may come out of the charging port. The detachment of the charging connector during the charging is not preferable because the power feeding path for charging is a strong electric system.

本発明は、充電ポートに対する充電コネクタの挿入が完了すると充電コネクタの外脱防止が機械的に行われるよう改良することで、上記のような充電中における充電コネクタの外脱に関する問題が決して起きることのないにした車両用外部充電器接続構造を提供することを目的とする。   According to the present invention, when the insertion of the charging connector into the charging port is completed, the charging connector is mechanically prevented from being detached, so that the above-described problem regarding the removal of the charging connector during charging never occurs. An object of the present invention is to provide an external charger connection structure for a vehicle that is free from any problem.

この目的のため、本発明による車両用外部充電器接続構造は、これを以下のごとくに構成する。
先ず本発明の前提となる車両用外部充電器接続構造を説明するに、これは、
車両用外部充電器の充電コネクタを挿入され、該挿入状態でこの充電コネクタから電力供給を受けて車載バッテリを充電可能にする充電ポートと、
該充電ポートに対する前記充電コネクタの挿脱方向を横切る方向へ進退して、前記挿入状態の充電コネクタが充電ポートから外脱するのを防止または許容する充電コネクタ外脱制限部材とを具備したものである。 For this purpose, the vehicle external charger connection structure according to the present invention is configured as follows.
First, in order to explain the external charger connection structure for a vehicle that is a premise of the present invention,
A charging port that is inserted into a charging connector of an external charger for a vehicle and that can be charged with an in-vehicle battery by receiving power supply from the charging connector in the inserted state;
A charging connector detachment restricting member for preventing or allowing the charging connector in the inserted state from detaching from the charging port by moving forward and backward in a direction crossing the inserting / removing direction of the charging connector with respect to the charging port; is there.

本発明の車両用外部充電器接続構造は、上記基本構成における充電コネクタ外脱制限部材に対し以下のような工夫を凝らして、充電コネクタ外脱防止機能を果たし得ないまま充電が行われることが決していないようにしたものである。   In the vehicle external charger connecting structure of the present invention, the charging connector detachment limiting member in the basic configuration described above has been devised as follows, and charging can be performed without fulfilling the charging connector detachment preventing function. It is something that is never.

つまり前記充電コネクタ外脱制限部材は、前記外脱防止を司る外脱防止用脚部と、前記充電ポートに対する前記充電コネクタの挿入時に該充電コネクタの挿入方向先端面により押圧される充電コネクタ押圧脚部を一体化して具えると共に、これら外脱防止用脚部および充電コネクタ押圧脚部の一体ユニットを、前記充電コネクタの挿入方向先端面より径方向外方にオフセットした揺動中心周りに枢支して、前記充電コネクタの挿入中に該充電コネクタの挿入方向先端面が前記充電コネクタ押圧脚部を押すとき、該充電コネクタ押圧脚部が充電コネクタの挿入方向先端面上をスリップしながら前記揺動中心周りで、前記外脱防止用脚部が前記充電コネクタの挿脱を許容する後退位置となる充電コネクタ挿脱許容位置から、前記外脱防止用脚部が前記充電コネクタの外脱を防止する進出位置となる充電コネクタ外脱防止位置へ揺動されるよう構成する。   That is, the charging connector detachment restricting member includes a detaching prevention leg portion that controls the detachment prevention, and a charging connector pressing leg that is pressed by the front end surface of the charging connector when the charging connector is inserted into the charging port. And an integrated unit of the anti-detachment leg portion and the charging connector pressing leg portion is pivotally supported around a swing center offset radially outward from the front end surface of the charging connector in the insertion direction. Then, when the front end surface of the charging connector in the insertion direction pushes the charging connector pressing leg during the insertion of the charging connector, the charging connector pressing leg slips on the front end surface of the charging connector in the insertion direction. From the charging connector insertion / removal allowable position where the anti-extraction-preventing leg is a retracted position allowing the insertion / removal of the charging connector around the moving center Serial to configured to be swung to the charging connector out de-preventing position to the advanced position to prevent the outer removal of charge connector.

上記した本発明の車両用外部充電器接続構造によれば、
充電ポートに対する充電コネクタの挿入時に、充電コネクタの挿入方向先端面が充電コネクタ押圧脚部を押し、この時、外脱防止用脚部および充電コネクタ押圧脚部の一体ユニットになる充電コネクタ外脱制限部材の揺動中心が上記の通りにオフセットされていることから、
外脱防止用脚部および充電コネクタ押圧脚部の一体ユニットになる充電コネクタ外脱制限部材は揺動中心周りの回転モーメントを入力され、外脱防止用脚部が後退位置になる充電コネクタ挿脱許容位置から、外脱防止用脚部が充電コネクタの外脱を防止する進出位置になる充電コネクタ外脱防止位置へと回動される。 According to the vehicle external charger connection structure of the present invention described above,
When the charging connector is inserted into the charging port, the front end surface of the charging connector in the insertion direction pushes the charging connector pressing leg, and at this time, the charging connector removal restriction becomes an integrated unit of the anti-detachment leg and the charging connector pressing leg. Since the swing center of the member is offset as described above,
The charging connector detachment restricting member, which is an integrated unit of the detachment prevention leg and the charging connector pressing leg, receives the rotational moment around the swing center, and the detachment prevention leg becomes the retracted position. From the permissible position, the anti-detachment leg is rotated to the charge connector anti-detachment position which becomes the advance position where the anti-extraction of the charging connector is prevented.

よって、充電ポートに対する充電コネクタの挿入が完了すると、外脱防止用脚部により充電コネクタの外脱防止が機械的に行われることとなる。
従って、充電コネクタの挿入完了で充電が開始されたときは、充電コネクタの挿入完了によって必ず充電コネクタの外脱防止が行われており、充電中に充電コネクタが外脱されてしまう従来の懸念を払拭することができる。 Therefore, when the insertion of the charging connector into the charging port is completed, the charging connector is mechanically prevented from being detached by the removal preventing leg.
Therefore, when charging is started upon completion of insertion of the charging connector, removal of the charging connector is always prevented by completion of insertion of the charging connector, and there is a conventional concern that the charging connector is detached during charging. Can be wiped off.

以下、本発明の実施の形態を、図面に示す実施例に基づき詳細に説明する。
＜実施例の構成＞
図1は、本発明の一実施例になる車両用外部充電器接続構造を具えた車両の前半分を、外部充電状態で示す側面図である。
図中1は、車両用外部充電器である充電スタンド、2は、充電コネクタをそれぞれ示し、これら充電スタンド1および充電コネクタ2間を電源ケーブル3によって接続する。 Hereinafter, embodiments of the present invention will be described in detail based on examples shown in the drawings.
<Configuration of Example>
FIG. 1 is a side view showing a front half of a vehicle provided with a vehicle external charger connection structure according to an embodiment of the present invention in an externally charged state.
In the figure, reference numeral 1 denotes a charging stand which is an external battery charger, and 2 denotes a charging connector, and the charging stand 1 and the charging connector 2 are connected by a power cable 3.

車両4は、床下に強電バッテリ5を収納して具え、当該バッテリ5の電力により、ボンネットフード6の下方に画成されたモータルーム内のモータ/ジェネレータ（図示せず）を駆動して走行するものとする。
車両4は更に、上記モータルームの前方空所内に収納して充電ポート7を具え、当該充電ポート収納空所の上方開口部を開閉蓋8により塞ぐことにより充電ポート7への塵埃の侵入を防ぐ。
車載バッテリ5および充電ポート7間を充電ケーブル9により電気接続する。 The vehicle 4 is provided with a high-power battery 5 housed under the floor, and travels by driving a motor / generator (not shown) in a motor room defined below the hood 6 with the electric power of the battery 5. Shall.
The vehicle 4 is further housed in a space in the front of the motor room and includes a charging port 7. The upper opening of the charging port housing space is closed with an opening / closing lid 8 to prevent dust from entering the charging port 7. .
The in-vehicle battery 5 and the charging port 7 are electrically connected by the charging cable 9.

車載バッテリ5への充電に際しては、通常は閉じている開閉蓋8を図1に示すごとくに開いて充電ポート7を露出させ、この充電ポート7に充電コネクタ2を図2のごとく挿入して両者間を電気接続する。
この状態で充電スタンド1の操作により、当該充電スタンド1の電力を順次、電源ケーブル3、充電コネクタ2、充電ポート7、および充電ケーブル9を経てバッテリ5に向かわせ、これへの充電を行う。
充電完了後は、自動的に、または充電スタンド1の操作により上記の給電を終了させ、その後に充電コネクタ2を充電ポート7から引き抜いて外脱し、更に開閉蓋8を図1の開位置から閉位置となす。 When charging the in-vehicle battery 5, the normally closed lid 8 is opened as shown in FIG. 1 to expose the charging port 7, and the charging connector 2 is inserted into the charging port 7 as shown in FIG. Electrical connection between them.
In this state, by operating the charging stand 1, the power of the charging stand 1 is sequentially directed to the battery 5 via the power cable 3, the charging connector 2, the charging port 7, and the charging cable 9, and charging is performed.
After charging is completed, the above power feeding is terminated automatically or by operating the charging stand 1, and then the charging connector 2 is pulled out from the charging port 7 to be removed, and the opening / closing lid 8 is closed from the open position in FIG. And position.

＜充電コネクタ外脱防止機構＞
ところで上記の外部充電器接続構造において、充電コネクタ2を充電ポート7に挿入した状態で行うバッテリ充電中に充電ポート7から充電コネクタ2が抜けて外脱することは、充電用の給電路が強電系であることともあって、好ましくない。 <Charging connector removal prevention mechanism>
By the way, in the above external charger connection structure, when the charging connector 2 is inserted into the charging port 7 and the charging connector 2 is disconnected from the charging port 7 during battery charging, the charging power supply path is a strong power. Since it is a system, it is not preferable.

そこで、充電コネクタ2が充電中に充電ポート7から外脱することのないようにする必要があり、本実施例ではそのための充電コネクタ外脱防止機構を図2に示すごとく、充電ポート7に設けた充電コネクタ外脱制限部材11と、その外脱防止用脚部であるロックピン11aの図示する進出位置でその進出方向先端部分が陥入するよう充電コネクタ2に設けたロック孔2aとで構成する。
なお充電コネクタ2に設けるロック孔2aは、図2に示す充電コネクタ2の挿入完了位置で、進出位置のロックピン11aに整列するよう配置する。 Therefore, it is necessary to prevent the charging connector 2 from being detached from the charging port 7 during charging. In this embodiment, a charging connector removal prevention mechanism is provided in the charging port 7 as shown in FIG. The charging connector detachment restricting member 11 and a lock hole 2a provided in the charging connector 2 so that the leading end portion of the lock pin 11a, which is a leg portion for preventing the detachment, is inserted at the illustrated advance position. To do.
The lock hole 2a provided in the charging connector 2 is arranged so as to be aligned with the lock pin 11a at the advanced position at the insertion completion position of the charging connector 2 shown in FIG.

充電コネクタ外脱制限部材11は後で詳述するが、ロックピン11aを一方の脚部（外脱防止用脚部）として有するほか、これと対向する他方の脚部として充電コネクタ押圧脚部11bを有し、ロックピン11a（外脱防止用脚部）が図2の進出位置になるとき、このロックピン11aの進出方向先端部分が充電コネクタ2のロック孔2a内に陥入し、両者の係合によって充電コネクタ2が充電ポート7から外脱するのを防止することができる。   As will be described in detail later, the charging connector removal / removal restricting member 11 has a lock pin 11a as one leg (an anti-detachment leg) and the charging connector pressing leg 11b as the other leg facing the lock pin 11a. When the lock pin 11a (extraction prevention leg) is in the advanced position of FIG. 2, the forward end of the lock pin 11a is inserted into the lock hole 2a of the charging connector 2, It is possible to prevent the charging connector 2 from coming off the charging port 7 by the engagement.

上記したようにロックピン11a（外脱防止用脚部）で充電コネクタ2の外脱防止を司る充電コネクタ外脱制限部材11は図2,3に示すごとく、このロックピン11a（外脱防止用脚部）および充電コネクタ押圧脚部11bを相互に結合して一体化した略U字状の一体ユニットに構成する。
そして、これら脚部11a,11bの一体ユニットに成る充電コネクタ外脱制限部材11は、充電コネクタ2の挿入方向前方に配した枢支ピン12によって充電ポート7に揺動可能に支持し、この枢支ピン12は充電コネクタ2に対し直角をなす方向へ延在させると共に充電コネクタ2から径方向外方にβだけオフセットさせて充電ポート7に取着する。 As described above, as shown in FIGS. 2 and 3, the lock connector 11, which is used to prevent the charging connector 2 from being detached by the lock pin 11 a (the anti-extraction leg), is provided with the lock pin 11 a (for preventing the anti-detachment). Leg) and charging connector pressing leg 11b are coupled to each other to form a substantially U-shaped integrated unit.
The charging connector removal / removal restricting member 11, which is an integrated unit of the legs 11a and 11b, is swingably supported on the charging port 7 by a pivot pin 12 disposed in front of the charging connector 2 in the insertion direction. The support pin 12 extends in a direction perpendicular to the charging connector 2 and is offset from the charging connector 2 radially outward by β to be attached to the charging port 7.

充電コネクタ外脱制限部材11は図３に示すごとく、圧縮バネ13により枢支ピン12の周りで同図の時計方向へ回動附勢し、この回動をストッパー14により図３(a)の限界位置に弾支する。
なお、図３(a)に示す充電コネクタ外脱制限部材11の限界位置は、ロックピン11a（外脱防止用脚部）が充電コネクタ2のロック孔2aから後退して充電コネクタ2の外脱防止を解除した充電コネクタ挿脱許容位置である。 As shown in FIG. 3, the charging connector removal / removal limiting member 11 is urged to rotate around the pivot pin 12 by the compression spring 13 in the clockwise direction in FIG. Support the limit position.
3A, the limit position of the charging connector removal / removal restricting member 11 is such that the lock pin 11a (extraction preventing leg) is retracted from the lock hole 2a of the charging connector 2 and the charging connector 2 is removed. This is the charging connector insertion / removal allowable position where the prevention is released.

かかる充電コネクタ挿脱許容位置の充電コネクタ外脱制限部材11を本実施例では、図３(b),(c)に示した充電ポート7に対する充電コネクタ2の挿入過程で充電コネクタ2の挿入方向先端面2bが充電コネクタ押圧脚部11bを押圧してこれとの協働により機械的に、ロックピン11a（外脱防止用脚部）が充電コネクタ2のロック孔2a内に進出して充電コネクタ2の外脱防止を行う図３(c)の充電コネクタ外脱防止位置へ回動させ得るよう、充電コネクタ押圧脚部11bを以下の構成となす。   In this embodiment, the charging connector removal / removal restricting member 11 at the charging connector insertion / removal allowing position is inserted in the charging connector 2 insertion process with respect to the charging port 7 shown in FIGS. 3 (b) and 3 (c). The front end surface 2b presses the charging connector pressing leg 11b and mechanically cooperates with the charging connector pressing leg 11b, and the lock pin 11a (extraction prevention leg) advances into the locking hole 2a of the charging connector 2 to charge the charging connector. The charging connector pressing leg portion 11b is configured as follows so that it can be rotated to the charging connector removal preventing position shown in FIG.

図４〜７により詳述するに充電コネクタ押圧脚部11bは、充電コネクタ外脱制限部材11との結合を司る基端11cを有し、当該充電コネクタ押圧脚部11bの基端11cは枢支ピン12を中心とする半径Roの円弧状として、充電ポート7の防水シール15に液密封止下に貫通させる。
充電コネクタ押圧脚部11bは更に、基端11cから充電コネクタ2の挿入経路内に張り出して、充電コネクタ2の挿入中にその挿入方向先端面2bによって押される充電コネクタ押圧面11dを有する。 4 to 7, the charging connector pressing leg portion 11b has a base end 11c that controls the connection with the charging connector removal / restriction member 11, and the charging connector pressing leg portion 11b has a base end 11c that is pivotally supported. As a circular arc shape having a radius Ro with the pin 12 as the center, the waterproof seal 15 of the charging port 7 is penetrated under liquid tight sealing.
The charging connector pressing leg portion 11b further has a charging connector pressing surface 11d that projects from the base end 11c into the insertion path of the charging connector 2 and is pressed by the distal end surface 2b in the insertion direction during insertion of the charging connector 2.

この充電コネクタ押圧面11dは、枢支ピン12の周りにおける充電コネクタ押圧脚部11bの基端11cに係わる半径Roの円弧αよりも径方向外方位置にあって、該充電コネクタ押圧脚部11bの基端円弧αと同方向に凸の円筒面により構成する。
かかる円筒形状の充電コネクタ押圧面11dは、充電コネクタ2の挿入方向先端面2bが接する領域において、充電コネクタ押圧脚部11bの基端11cに近いほど曲率が小さな（曲率半径が大きな）円筒面とする。 The charging connector pressing surface 11d is located radially outward from the arc α of the radius Ro related to the base end 11c of the charging connector pressing leg 11b around the pivot pin 12, and the charging connector pressing leg 11b It is constituted by a cylindrical surface convex in the same direction as the base end arc α.
The cylindrical charging connector pressing surface 11d has a cylindrical surface with a smaller curvature (a larger radius of curvature) closer to the base end 11c of the charging connector pressing leg portion 11b in a region where the distal end surface 2b in the insertion direction of the charging connector 2 is in contact. To do.

なお充電コネクタ押圧面11dは、充電コネクタ2の挿入方向先端面2bが接する領域において、充電コネクタ押圧脚部11bの基端11cに近いほど、充電コネクタ押圧脚部11bの基端円弧αとの離間距離ΔRが短くなり、図6に示す充電コネクタ2の挿入完了時において充電コネクタ2の挿入方向先端面2bが接する充電コネクタ押圧面11dの箇所で離間距離ΔRが丁度0になる円筒面とする。   Note that the charging connector pressing surface 11d is closer to the base end arc α of the charging connector pressing leg 11b as it is closer to the base end 11c of the charging connector pressing leg 11b in the region where the distal end surface 2b of the charging connector 2 is in contact. The distance ΔR is shortened, and when the charging connector 2 shown in FIG. 6 is completely inserted, the cylindrical surface is such that the separation distance ΔR is exactly 0 at the position of the charging connector pressing surface 11d where the leading end surface 2b of the charging connector 2 contacts.

＜実施例の作用・効果＞
上記した実施例の充電コネクタ外脱防止機構にあっては、充電コネクタ2を充電ポート7に挿入する前の常態で、ロックピン11a（外脱防止用脚部）および充電コネクタ押圧脚部11bの一体ユニットに成る充電コネクタ外脱制限部材11が、バネ13により図３(a)に示す限界位置（充電コネクタ挿脱許容位置）に弾支されている。
かかる充電コネクタ外脱制限部材11の揺動位置では、ロックピン11a（外脱防止用脚部）が充電コネクタ2のロック孔2aから後退して充電コネクタ2の外脱防止を解除し、充電コネクタ2を充電ポート7に対し挿脱することができる。 <Operation / Effect of Example>
In the charging connector removal prevention mechanism of the above-described embodiment, the lock pin 11a (extraction prevention leg portion) and the charging connector pressing leg portion 11b are in a normal state before the charging connector 2 is inserted into the charging port 7. The charging connector removal / removal limiting member 11 which is an integrated unit is elastically supported by a spring 13 at a limit position (charging connector insertion / removal allowable position) shown in FIG.
At the swinging position of the charging connector removal limiting member 11, the lock pin 11a (extraction prevention leg) moves backward from the lock hole 2a of the charging connector 2 to release the charging connector 2 and prevent the charging connector 2 from coming off. 2 can be inserted into and removed from the charging port 7.

充電に際して充電コネクタ2を充電ポート7に挿入すると、充電コネクタ2の挿入方向先端面2bが先ず図3(a)および図4に示すごとく（図7に実線で示すごとく）充電コネクタ外脱制限部材11の充電コネクタ押圧脚部11bに接する。
この時より充電コネクタ2の挿入力は、オフセットβをアーム長とする枢支ピン12の周りにおける回転モーメントを充電コネクタ押圧脚部11bに付与する。 When the charging connector 2 is inserted into the charging port 7 during charging, the leading end surface 2b of the charging connector 2 is first inserted as shown in FIGS. 3 (a) and 4 (as indicated by the solid line in FIG. 7). 11 is in contact with the charging connector pressing leg 11b.
From this time, the insertion force of the charging connector 2 applies a rotational moment around the pivot pin 12 with the offset β as the arm length to the charging connector pressing leg 11b.

この回転モーメントは充電コネクタ押圧脚部11bを、充電コネクタ2の挿入方向先端面2b上でスリップさせながら枢支ピン12の周りに、図3(b)および図5の位置（図7に破線で示す位置）を経て、図3(c)および図６の位置（図7に二点鎖線で示す位置）へと回動させる。   This rotational moment causes the charging connector pressing leg 11b to slip around the pivot pin 12 while slipping on the front end surface 2b of the charging connector 2 in the insertion direction, as shown in FIG. 3 (b) and FIG. Through the position shown in FIG. 3 (c) and FIG. 6 (the position shown by the two-dot chain line in FIG. 7).

なお、かかる充電コネクタ押圧脚部11bの回動は、充電コネクタ2の挿入方向先端面2bと接する充電コネクタ押圧脚部11bの充電コネクタ押圧面11dが前記した通りのものであることによって助長され、更に確実に生起させることができる。
(1) 充電コネクタ押圧面11dが、枢支ピン12の周りにおける充電コネクタ押圧脚部11bの基端11cに係わる半径Roの円弧αよりも径方向外方位置にあって、該充電コネクタ押圧脚部11bの基端円弧αと同方向に凸の円筒面で構成されている。
(2)当該円筒面を充電コネクタ2の挿入方向先端面2bと接する領域において、充電コネクタ押圧脚部11bの基端11cに近いほど曲率が小さな（曲率半径が大きな）円筒面とし、充電コネクタ押圧脚部11bの基端11cに近いほど、充電コネクタ押圧脚部11bの基端円弧αから離間距離ΔRが短くなり、図6に示す（図7に二点鎖線で示す）充電コネクタ2の挿入完了時において充電コネクタ2の挿入方向先端面2bが接する充電コネクタ押圧面11dの箇所で当該離間距離ΔRが丁度0になる円筒面とする。 The rotation of the charging connector pressing leg portion 11b is facilitated by the fact that the charging connector pressing surface 11d of the charging connector pressing leg portion 11b in contact with the leading end surface 2b of the charging connector 2 is as described above. Furthermore, it can be surely generated.
(1) The charging connector pressing surface 11d is positioned radially outward from the arc α of the radius Ro related to the base end 11c of the charging connector pressing leg 11b around the pivot pin 12, and the charging connector pressing leg The cylindrical surface is convex in the same direction as the base end arc α of the portion 11b.
(2) In the region where the cylindrical surface is in contact with the distal end surface 2b of the charging connector 2 in the insertion direction, the cylindrical surface has a smaller curvature (a larger radius of curvature) closer to the base end 11c of the charging connector pressing leg 11b, and the charging connector pressing The closer to the base end 11c of the leg portion 11b, the shorter the distance ΔR from the base end arc α of the charging connector pressing leg portion 11b, and the insertion of the charging connector 2 shown in FIG. 6 (indicated by a two-dot chain line in FIG. 7) is completed. At this time, the charging connector 2 is assumed to be a cylindrical surface in which the separation distance ΔR is exactly 0 at the position of the charging connector pressing surface 11d where the leading end surface 2b of the charging connector 2 contacts.

充電コネクタ2の挿入ストロークに応動して充電コネクタ押圧脚部11bが上記のように、充電コネクタ2の挿入方向先端面2b上をスリップしながら枢支ピン12の周りで、図3(a)および図4の位置（図7に実線で示す位置）から、図3(b)および図5の位置（図7に破線で示す位置）を通過するよう回動され、充電コネクタ2の挿入完了時に充電コネクタ押圧脚部11bが図3(c)および図６の位置（図7に二点鎖線で示す位置）へ回動し終えると、
充電コネクタ外脱制限部材11のロックピン11a（外脱防止用脚部）が図2および図３(c)の進出位置となり、ロックピン11aの進出方向先端部分が充電コネクタ2のロック孔2a内に陥入し、両者の係合によって充電コネクタ2が充電ポート7から外脱するのを防止することができる。 In response to the insertion stroke of the charging connector 2, the charging connector pressing leg portion 11b slips on the distal end surface 2b in the insertion direction of the charging connector 2 as described above, around the pivot pin 12, FIG. 4 is rotated from the position shown in FIG. 4 (the position indicated by the solid line in FIG. 7) to the position shown in FIG. 3B and the position shown in FIG. 5 (the position indicated by the broken line in FIG. 7). When the connector pressing leg 11b has finished rotating to the position shown in FIG. 3 (c) and FIG. 6 (the position indicated by the two-dot chain line in FIG. 7),
The lock pin 11a (extraction prevention leg portion) of the charging connector removal restricting member 11 is the advanced position in FIGS. 2 and 3 (c), and the leading end portion of the lock pin 11a is in the lock hole 2a of the charging connector 2. It is possible to prevent the charging connector 2 from coming out of the charging port 7 due to the engagement between the two.

以上のように本実施例では、充電コネクタ2を充電ポート7に挿入する時、充電コネクタ2の挿入方向先端面2bが充電コネクタ押圧脚部11bを押して上記スリップ回動を生起させ、これにより充電コネクタ押圧脚部11bに一体のロックピン11a（外脱防止用脚部）が充電コネクタ2の挿入完了時にそのロック孔2a内に陥入して充電コネクタ2の外脱防止機能を発揮するため、
充電ポート7に対する充電コネクタ2の挿入が完了すると、ロックピン11a（外脱防止用脚部）により充電コネクタ2の外脱防止が機械的に行われることとなる。
従って、充電コネクタ2の挿入完了で充電が開始されたときは、充電コネクタ2の挿入完了によって必ず充電コネクタ2の外脱防止が行われており、充電中に充電コネクタ2が外脱されてしまう従来の懸念を払拭することができる。 As described above, in this embodiment, when the charging connector 2 is inserted into the charging port 7, the tip end surface 2b of the charging connector 2 in the insertion direction presses the charging connector pressing leg portion 11b to cause the above-mentioned slip rotation, thereby charging. Since the lock pin 11a (extraction prevention leg) integrated with the connector pressing leg 11b is inserted into the lock hole 2a when the insertion of the charging connector 2 is completed, the charging connector 2 is prevented from coming off.
When the insertion of the charging connector 2 into the charging port 7 is completed, the charging connector 2 is mechanically prevented from coming off by the lock pin 11a (outgoing prevention leg).
Therefore, when charging is started when the insertion of the charging connector 2 is completed, the charging connector 2 is always prevented from being detached by the completion of the insertion of the charging connector 2, and the charging connector 2 is detached during charging. Traditional concerns can be dispelled.

しかも本実施例では、充電コネクタ2の挿入方向先端面2bと接する充電コネクタ押圧脚部11bの充電コネクタ押圧面11dを前記したような円筒面で構成したため、上記の作用・効果を得るのに不可欠な充電コネクタ押圧脚部11bの上記スリップ回動が助長されることとなり、上記の作用・効果を更に確実なものとなし得る。   In addition, in this embodiment, the charging connector pressing surface 11d of the charging connector pressing leg 11b that contacts the distal end surface 2b in the insertion direction of the charging connector 2 is configured by the cylindrical surface as described above, which is indispensable for obtaining the functions and effects described above. The above-described slip rotation of the charging connector pressing leg portion 11b is promoted, and the above-described operation and effect can be further ensured.

なお充電完了後は、自動的に、または充電スタンド1の操作により、充電用の給電を終了させるが、これに応答して任意の機構により自動的に、または手動で、充電コネクタ外脱制限部材11（充電コネクタ押圧脚部11b）を枢支ピン12の周りで、図3(c)および図６の位置（図7に二点鎖線で示す位置）から図3(b)および図5の位置（図7に破線で示す位置）を経て図3(a)および図4の位置（図7に実線で示す位置）へと回動させる。
かかる充電コネクタ外脱制限部材11（充電コネクタ押圧脚部11b）の回動は、圧縮バネ13によって助勢されるため、小さなエネルギーで軽快に行うことができる。 After charging is completed, charging power supply is terminated automatically or by operating the charging stand 1, but in response to this, the charging connector removal limiting member is automatically or manually by any mechanism. 11 (charging connector pressing leg 11b) around the pivot pin 12 from the position shown in FIG. 3 (c) and FIG. 6 (the position indicated by the two-dot chain line in FIG. 7) to the position shown in FIG. 3 (b) and FIG. It is rotated to the position shown in FIG. 3 (a) and FIG. 4 (position indicated by the solid line in FIG. 7) via (the position indicated by the broken line in FIG. 7).
Since the rotation of the charging connector removal restriction member 11 (charging connector pressing leg portion 11b) is assisted by the compression spring 13, it can be easily performed with small energy.

かかる充電コネクタ外脱制限部材11（充電コネクタ押圧脚部11b）の回動中、ロックピン11a（外脱防止用脚部）が充電コネクタ2のロック孔2aから後退されて充電コネクタ2の外脱防止を解除すると同時に、充電コネクタ押圧脚部11bが充電コネクタ2を外脱方向へストロークさせ、以後は充電コネクタ2を手で充電ポート7から引き抜くことができる。   During rotation of the charging connector removal / removal restricting member 11 (charging connector pressing leg portion 11b), the lock pin 11a (extraction preventing leg portion) is retracted from the lock hole 2a of the charging connector 2 so that the charging connector 2 is removed. Simultaneously with the release of the prevention, the charging connector pressing leg 11b strokes the charging connector 2 in the outward direction, and thereafter the charging connector 2 can be pulled out from the charging port 7 by hand.
