Abstract

The purpose of the present invention is to provide a technique for making a lid readily openable in a connector for charging. A charging connector (10) comprises a housing (50), a lid (80), and a locking member (87). The locking member (87) has: a to-be-supported part (87a) that is supported on a shaft (88a); and a locking part (87b) and a protrusion (87c), each of which protrudes radially outward from the to-be-supported part (87a). In the case when the locking member (87) is situated at a first position, the locking part (87b) is capable of locking onto the lid (80) that is in a closed state, and the protrusion (87c) is situated inward of a leading end of a cylindrical frame (52) of the housing (50) along the insertion/extraction direction with respect to an external charging connector. When the locking member (87) is rotated from the first position to a second position, the locking state between the locking part (87b) and the lid (80) is cancelled, and the protrusion (87c) becomes situated outward of the leading end of the cylindrical frame (52) along the insertion/extraction direction.

　［本開示の実施形態の説明］
　最初に本開示の実施態様を列記して説明する。 [Description of Embodiments of the Present Disclosure]
First, the embodiments of the present disclosure are listed and described.
　本開示の充電コネクタは、次の通りである。 The charging connector of the present disclosure is as follows.
　（１）車両に搭載され、前記車両の外部電源に接続される外部充電コネクタと篏合し、前記車両に備えられるバッテリの充電に用いられる充電コネクタであって、前記外部充電コネクタが挿抜可能な筒状枠部を有するハウジングと、前記筒状枠部の先端側に開閉可能に取付けられたリッドと、軸部を介して前記筒状枠部に対して第１位置と第２位置との間で回動可能に支持された係止部材と、を備え、前記係止部材は、前記軸部に支持される被支持部と、それぞれが前記被支持部から径方向外側に突出する係止部及び突出部とを有し、前記係止部材が前記第１位置にある場合において、前記係止部は閉状態の前記リッドに係止可能であると共に、前記突出部は前記外部充電コネクタとの挿抜方向に沿って前記筒状枠部の先端より内側に位置し、前記係止部材が前記第１位置から前記第２位置に回動して、前記係止部と前記リッドとの係止状態が解消されると共に、前記突出部が前記挿抜方向に沿って前記筒状枠部の先端より外側に位置する、充電コネクタである。係止部材が第１位置から第２位置に回動する際、突出部がリッドを押し上げ可能な位置に設けられているため、凍結時などにリッド及びハウジングが固着している場合においても、リッドが開きやすくなる。また、突出部がリッドを押し上げる動作が、係止部材が第１位置から第２位置に回動する動作に組込まれるため、作業者が行う動作が増えることが抑制される。 (1) A charging connector that is mounted on a vehicle, is mated with an external charging connector that is connected to an external power source of the vehicle, and is used for charging a battery provided in the vehicle, wherein the external charging connector is insertable and removable. A housing having a tubular frame, a lid attached to the tip of the tubular frame so as to be openable and closable, and a shaft between a first position and a second position with respect to the tubular frame. and a locking member rotatably supported by the shaft, wherein the locking member includes a supported portion supported by the shaft portion, and locking portions protruding radially outward from the supported portion. and a projecting portion, and when the locking member is in the first position, the locking portion can be locked to the lid in the closed state, and the projecting portion is connected to the external charging connector. The locking member is positioned inside the tip of the cylindrical frame along the inserting/removing direction, and rotates from the first position to the second position to lock the locking portion and the lid. is eliminated, and the projecting portion is located outside the tip of the cylindrical frame portion along the insertion/removal direction. When the locking member rotates from the first position to the second position, the projecting portion is provided at a position where the lid can be pushed up. becomes easier to open. In addition, since the action of the projecting portion pushing up the lid is included in the action of rotating the locking member from the first position to the second position, an increase in the number of actions performed by the operator is suppressed.
　（２）（１）の充電コネクタにおいて、前記係止部材は、前記係止部の天面に形成され、前記軸部の延在方向に沿って延びる一条の凸部をさらに有してもよい。これにより、作業者が係止部材を操作する際、凸部が引掛かりとなって滑りにくくなり、係止部材の操作が容易となる。 (2) In the charging connector of (1), the locking member may further have a single convex portion formed on the top surface of the locking portion and extending along the extending direction of the shaft portion. . As a result, when an operator operates the locking member, the convex portion becomes a hook and does not slip easily, making it easy to operate the locking member.
　（３）（２）の充電コネクタにおいて、前記凸部は、前記天面のうち前記リッドから遠い側の端部に設けられていてもよい。これにより、作業者が係止部材を第１位置から第２位置に操作する際、凸部が引掛かりとなりやすい。 (3) In the charging connector of (2), the convex portion may be provided at an end of the top surface farther from the lid. As a result, when an operator operates the locking member from the first position to the second position, the convex portion is likely to be caught.
　（４）（１）から（３）のいずれか１つの充電コネクタにおいて、前記リッドの内面に設けられ、前記リッドが閉状態のときに前記筒状枠部の端面と接触する環状のシール部材をさらに備え、前記リッドの内面には、前記シール部材の内側に沿って延びる環状の第１リブが形成されていてもよい。これにより、リッドにリッドとは別部材であるシール部材が設けられる際、第１リブが位置決めに使用されることができる。 (4) In the charging connector according to any one of (1) to (3), an annular seal member provided on the inner surface of the lid and in contact with the end surface of the tubular frame when the lid is closed. Further, the inner surface of the lid may be formed with an annular first rib extending along the inner side of the seal member. This allows the first rib to be used for positioning when the lid is provided with a sealing member that is a separate member from the lid.
　（５）（４）の充電コネクタにおいて、前記リッドの内面には、前記リッドの中央部から前記第１リブに向かって放射状に延びる複数の第２リブが形成されていてもよい。これにより、リッドの剛性が高められる。 (5) In the charging connector of (4), a plurality of second ribs radially extending from the central portion of the lid toward the first rib may be formed on the inner surface of the lid. This increases the rigidity of the lid.
　（６）（５）の充電コネクタにおいて、前記リッドの内面には、前記第１リブの内側に環状の第３リブが形成されており、前記複数の第２リブは、前記第３リブを起点として前記第１リブに向けて延びていてもよい。これにより、中央部において複数の第２リブが交わることが抑制され、リッドの成形性が高まる。 (6) In the charging connector of (5), an annular third rib is formed inside the first rib on the inner surface of the lid, and the plurality of second ribs start from the third rib. , may extend toward the first rib. This prevents the plurality of second ribs from intersecting in the central portion, thereby enhancing the moldability of the lid.
　（７）（１）から（６）のいずれか１つの充電コネクタにおいて、前記係止部材は、前記被支持部の外面から前記軸部の延在方向に沿って前記ハウジングの軸受部に突出するスペーサ部をさらに有し、前記スペーサ部の周囲の位置において、前記被支持部の前記外面と前記軸受部の内面とが互いに離間しつつ対向していてもよい。これにより、係止部材とハウジングとの接触面積が小さくなり、係止部材とハウジングとが凍結などにより固着していても、作業者による係止部材の操作の弊害となることが抑制される。 (7) In the charging connector according to any one of (1) to (6), the locking member protrudes from the outer surface of the supported portion toward the bearing portion of the housing along the extending direction of the shaft portion. A spacer portion may be further provided, and the outer surface of the supported portion and the inner surface of the bearing portion may face each other while being separated from each other at a position around the spacer portion. As a result, the contact area between the locking member and the housing is reduced, and even if the locking member and the housing are fixed due to freezing or the like, the operator's operation of the locking member is prevented from being adversely affected.
　（８）（１）から（７）のいずれか１つの充電コネクタにおいて、前記リッドは、前記筒状枠部を覆うリッド本体と、前記係止部に引っ掛かる被係止部とを有し、前記被係止部は、前記リッド本体よりも外周側に突出し、前記被係止部の外面は、前記リッド本体の外面より前記筒状枠部側に低くなっていてもよい。これにより、車外方向に向かう係止部の突出寸法が小さくなる。 (8) In the charging connector according to any one of (1) to (7), the lid has a lid body that covers the tubular frame and a locked portion that is caught by the locking portion, The locked portion may protrude further outward than the lid body, and the outer surface of the locked portion may be lower toward the tubular frame than the outer surface of the lid body. As a result, the projection dimension of the engaging portion toward the outside of the vehicle is reduced.
　（９）（１）から（８）のいずれか１つの充電コネクタにおいて、前記係止部材を回動方向に沿って前記第１位置に向けて付勢する係止部材側付勢部材をさらに備えてもよい。これにより、突出部がリッドを押し上げる動作が、作業者が係止部材側付勢部材の付勢力に抗して、係止部材を第１位置から第２位置に向けて回動させる動作に組込まれる。 (9) The charging connector according to any one of (1) to (8), further comprising a locking member-side biasing member that biases the locking member toward the first position along the rotation direction. may As a result, the action of the projection pushing up the lid is incorporated into the action of the operator rotating the locking member from the first position toward the second position against the biasing force of the biasing member on the side of the locking member. be
　（１０）（１）から（９）のいずれか１つの充電コネクタにおいて、前記リッドは、リッド側軸部を介して前記ハウジングに回動可能に取付けられ、前記リッドを回動方向に沿って開状態に付勢するリッド側付勢部材をさらに備えてもよい。これにより、突出部によるリッドの押し上げ動作によってリッドとハウジングとの固着部分を剥がすきっかけが与えられると、リッド側付勢部材によって閉状態から開状態に移行することができる。 (10) In the charging connector according to any one of (1) to (9), the lid is rotatably attached to the housing via a lid-side shaft portion, and the lid is opened along the rotation direction. A lid-side biasing member that biases to the state may be further provided. Thus, when the lid is pushed up by the protruding portion and a trigger is given to peel off the fixed portion between the lid and the housing, the closed state can be shifted to the open state by the lid-side biasing member.
　（１１）（１０）の充電コネクタにおいて、前記リッド側付勢部材は、ばね本体部と、前記ばね本体部から延びるばねアーム部とを含み、前記リッド及び前記ハウジングの少なくとも一方には、前記リッド側付勢部材の取付姿勢が正規姿勢とは異なる姿勢の場合に前記ばねアーム部と干渉する干渉部が設けられていてもよい。これにより、リッド側付勢部材が正規姿勢とは異なる姿勢で取付けられることが抑制される。 (11) In the charging connector of (10), the lid side biasing member includes a spring main body portion and a spring arm portion extending from the spring main body portion, and at least one of the lid and the housing includes the lid. An interference portion may be provided that interferes with the spring arm portion when the mounting posture of the side biasing member is different from the normal posture. This prevents the lid-side biasing member from being attached in a posture different from the normal posture.

The charging connector according to the first embodiment will be described below.
　＜車両について＞
　まず、充電コネクタが組込まれる車両について説明する。 <About the vehicle>
First, a vehicle in which a charging connector is incorporated will be described.
　充電コネクタが組込まれる車両は、蓄電装置及びモータを備える電動車両である。車両は、蓄電装置の電力によってモータが駆動されることによって走行する。車両は、駆動源としてモータのみを備える電気自動車であってもよいし、モータとエンジンとを備えるハイブリッド自動車であってもよい。車両における蓄電装置は、外部の電源から供給される電力によって充電される。充電コネクタは、外部充電コネクタが挿し込まれて電気的に接続されることが可能に構成される。外部充電コネクタは、外部電源から延びる充電ケーブルのコネクタである。 A vehicle that incorporates a charging connector is an electric vehicle that includes a power storage device and a motor. The vehicle runs by driving the motor with the electric power of the power storage device. The vehicle may be an electric vehicle having only a motor as a drive source, or a hybrid vehicle having a motor and an engine. A power storage device in a vehicle is charged with electric power supplied from an external power supply. The charging connector is configured such that an external charging connector can be inserted and electrically connected. The external charging connector is a connector for a charging cable extending from an external power supply.
　車両における蓄電装置の充電態様として、一般に、普通充電及び急速充電がある。急速充電は、普通充電よりも大きな電流を流すことによって、普通充電よりも短時間での充電を可能にする。普通充電は、家庭用電源又はそれと同等の外部電源が用いられることが想定される。急速充電では、例えば充電スタンドなどの専用の電源が用いられることが想定される。本開示の充電コネクタは、急速充電に対応した充電コネクタであるものとして説明される。 　Generally, there are normal charging and rapid charging as charging modes for the power storage device in the vehicle. Rapid charging enables charging in a shorter time than normal charging by allowing a larger current to flow than normal charging. For normal charging, it is assumed that a household power source or an equivalent external power source is used. In rapid charging, it is assumed that a dedicated power supply such as a charging stand is used. The charging connector of the present disclosure will be described as a charging connector that supports rapid charging.

Referring to FIG. 1, a manner of assembling a charging connector in a vehicle will be described. FIG. 1 is a plan view showing a charging connector 10 according to Embodiment 1 and its assembly mode.
　充電コネクタ１０は、例えば、車両におけるボディの外面に設けられた取付部１００に取付けられる。図１には、取付部１００の一例が示されている。取付部１００は、例えば、ボディをなすパネル１０２の一部が車両の内側に凹む凹状に形成される。取付部１００のうち底部のパネル１０２には貫通孔１０４が形成される。 The charging connector 10 is attached, for example, to an attachment portion 100 provided on the outer surface of the body of the vehicle. An example of the mounting portion 100 is shown in FIG. The mounting portion 100 is formed, for example, in a concave shape in which a portion of a panel 102 forming the body is concave inside the vehicle. A through hole 104 is formed in the bottom panel 102 of the mounting portion 100 .
　充電コネクタ１０の正面側には、外部充電コネクタとの接続部分が設けられる。接続部分は、外部充電コネクタが挿し込まれて電気的に接続される部分を含む。充電コネクタ１０における接続部分を含む一部は、貫通孔１０４を貫通してパネル１０２の外側に露出する。充電コネクタ１０の他の一部は、パネル１０２よりも車両の内側に配置される。通常、取付部１００には、車体側カバー１０６が設けられる。車体側カバー１０６は、ヒンジ等によって開閉可能にパネル１０２に取付けられる。車体側カバー１０６が閉じた状態で、車体側カバー１０６がパネル１０２の開口部を覆う。車体側カバー１０６が開いた状態で、充電コネクタ１０が露出し、外部から充電コネクタ１０へのアクセスが可能となる。 A connecting portion with an external charging connector is provided on the front side of the charging connector 10 . The connecting portion includes a portion into which an external charging connector is inserted and electrically connected. A portion of charging connector 10 , including the connection portion, penetrates through hole 104 and is exposed to the outside of panel 102 . Another part of charging connector 10 is arranged inside the vehicle rather than panel 102 . Usually, the mounting portion 100 is provided with a vehicle body side cover 106 . The vehicle body side cover 106 is attached to the panel 102 by a hinge or the like so that it can be opened and closed. The vehicle body side cover 106 covers the opening of the panel 102 when the vehicle body side cover 106 is closed. When the vehicle body side cover 106 is opened, the charging connector 10 is exposed and can be accessed from the outside.
　本開示において、図１に示されるように、互いに直交するＸ方向、Ｙ方向及びＺ方向のうち、Ｘ方向が、充電コネクタ１０がパネル１０２の貫通孔１０４を貫通する方向に平行な方向とされる。充電コネクタ１０と外部充電コネクタとは、Ｘ方向に接続される。Ｚ方向は、例えば、鉛直方向である。例えば、充電コネクタ１０が車両の側面に設けられる場合、Ｙ方向は車両の前後方向となる。例えば、充電コネクタ１０が車両の前面又は後面に設けられる場合、Ｙ方向は車両の幅方向となる。以下、取付状態にない部材についても、取付状態とされた場合のＸ方向、Ｙ方向及びＺ方向に対応する方向に準ずる説明がなされる。 In the present disclosure, as shown in FIG. 1, of the X, Y, and Z directions that are orthogonal to each other, the X direction is parallel to the direction in which the charging connector 10 penetrates the through hole 104 of the panel 102. be. The charging connector 10 and the external charging connector are connected in the X direction. The Z direction is, for example, the vertical direction. For example, when charging connector 10 is provided on the side of the vehicle, the Y direction is the front-rear direction of the vehicle. For example, when charging connector 10 is provided on the front or rear surface of the vehicle, the Y direction is the width direction of the vehicle. In the following description, the members that are not in the attached state are also explained according to the directions corresponding to the X, Y, and Z directions when they are in the attached state.

The number and type of connector terminals 21 are appropriately set according to the standard of charging connector 10 and the like. In the example of this embodiment, two power terminals 22 , six signal terminals 24 and one ground terminal 26 are provided as connector terminals 21 . The relay terminal 28 is interposed between the power terminal 22 and the electric wire 30 . The relay terminals 28 are provided in the same number as the power terminals 22 (here, two). Each terminal 20 is formed by pressing (bending) a metal plate.
　パワー端子２２は、相手側接続部２３ａ、端子固定部２３ｂ及び突出部２３ｃを有する。パワー端子２２は、サーミスタ取付部２３ｄをさらに有する。シグナル端子２４は、相手側接続部２５ａ、電線固定部２５ｂ及び突出部２５ｃを有する。グランド端子２６は、相手側接続部２７ａ、電線固定部２７ｂ及び突出部２７ｃを有する。中継端子２８は、端子固定部２９ａ及び電線固定部２９ｂを有する。 The power terminal 22 has a mating connection portion 23a, a terminal fixing portion 23b, and a projecting portion 23c.

　相手側接続部２３ａ、２５ａ、２７ａは、外部充電コネクタのコネクタ端子と電気的に接続される部分である。端子固定部２３ｂ、２９ａには、ねじＳを挿通可能な孔が形成されている。パワー端子２２と中継端子２８とは、端子固定部２３ｂ、２９ａにおいて、ねじＳによって固定されることによって、電気的に接続されつつ固定される。電線固定部２５ｂ、２７ｂ、２９ｂは、圧着部である。シグナル端子２４、グランド端子２６及び中継端子２８は、電線固定部２５ｂ、２７ｂ、２９ｂによって、それぞれ対応する電線３０の端部に圧着される。これにより、シグナル端子２４、グランド端子２６及び中継端子２８が、それぞれ対応する電線３０と電気的に接続されつつ固定される。突出部２３ｃ、２５ｃ、２７ｃは、各コネクタ端子２１の中間部に設けられる。突出部２３ｃ、２５ｃ、２７ｃは、リテーナ６０によって押さえられる部分である。サーミスタ取付部２３ｄは、サーミスタユニット４０が取付けられる部分である。 The mating connection portions 23a, 25a, and 27a are portions that are electrically connected to connector terminals of the external charging connector. Holes through which the screws S can be inserted are formed in the terminal fixing portions 23b and 29a. The power terminal 22 and the relay terminal 28 are electrically connected and fixed by being fixed by screws S at the terminal fixing portions 23b and 29a. The wire fixing portions 25b, 27b, and 29b are crimp portions. The signal terminal 24, the ground terminal 26, and the relay terminal 28 are crimped to the corresponding ends of the electric wires 30 by the electric wire fixing portions 25b, 27b, and 29b, respectively.

The thermistor mounting portion 23d is a portion to which the thermistor unit 40 is mounted.
　＜電線＞
　各電線３０の一端部は、端子２０に接続される。各電線３０の他端部は、グロメット９０から外部に延び出る。充電コネクタ１０が車両に搭載された状態で、各電線３０の他端部は、車両に搭載された別の機器に接続される。かかる機器は、電線３０の種類などに応じて適宜設定され、例えば、バッテリ、電子制御ユニット（ＥＣＵ）などが想定される。電線３０の数及び種類は、コネクタ端子２１の数及び種類に対応する。本実施形態の例では、電線３０は、２本の電力線３２、６本の信号線３４、及び１本のグランド線３６を含む。電力線３２の一端部は、中継端子２８に接続される。電力線３２は、中継端子２８を介してパワー端子２２と接続される。信号線３４の一端部は、シグナル端子２４に接続される。グランド線３６の一端部は、グランド端子２６に接続される。サーミスタ用電線４４の一端部は、サーミスタ４２に接続される。 <Electric wire>
One end of each wire 30 is connected to the terminal 20 . The other end of each electric wire 30 extends outside from the grommet 90 . With the charging connector 10 mounted on the vehicle, the other end of each electric wire 30 is connected to another device mounted on the vehicle. Such a device is appropriately set according to the type of the electric wire 30, and is assumed to be, for example, a battery, an electronic control unit (ECU), and the like. The number and types of wires 30 correspond to the number and types of connector terminals 21 . In the example of this embodiment, the wires 30 include two power lines 32 , six signal lines 34 and one ground line 36 . One end of the power line 32 is connected to the relay terminal 28 . The power line 32 is connected to the power terminal 22 via the relay terminal 28 . One end of the signal line 34 is connected to the signal terminal 24 . One end of the ground wire 36 is connected to the ground terminal 26 . One end of the thermistor electric wire 44 is connected to the thermistor 42 .
　各電線３０は、被覆電線である。被覆電線は、芯線３１ａと芯線３１ａを覆う被覆３１ｂとを有する。芯線３１ａは、例えば、金属製の複数の素線が撚られて形成される。被覆３１ｂは、例えば、絶縁性を有する樹脂が芯線３１ａの周りに押出成形されて形成される。複数の電線３０として、互いに太さが異なる複数種類の電線３０が用いられている。電線３０の太さは、許容電流値などに応じて設定される。通常、許容電流値を大きくするには、導体断面積を大きくする必要があり、その分、電線３０の太さが太くなる。また電線３０の太さは、通常、電線３０の曲りにくさと相関関係にあり、電線３０が太くなるにつれて、電線３０が曲りにくくなる。例えば、曲りやすい電線と曲りにくい電線とが同じ角度分曲げられたときに、曲りにくい電線の曲率半径は、曲りやすい電線の曲率半径よりも大きくなり、その分、大きな配置スペースが必要となる。 Each electric wire 30 is a covered electric wire. The coated electric wire has a core wire 31a and a coating 31b covering the core wire 31a. The core wire 31a is formed by, for example, twisting a plurality of metal strands. The coating 31b is formed by, for example, extruding an insulating resin around the core wire 31a. A plurality of types of electric wires 30 having different thicknesses are used as the electric wires 30 . The thickness of the electric wire 30 is set according to the allowable current value and the like. Generally, in order to increase the allowable current value, it is necessary to increase the cross-sectional area of the conductor, and the thickness of the electric wire 30 is increased accordingly. Also, the thickness of the electric wire 30 generally correlates with the difficulty of bending the electric wire 30, and the thicker the electric wire 30, the more difficult it is to bend the electric wire 30. For example, when an easy-to-bend electric wire and a hard-to-bend electric wire are bent by the same angle, the radius of curvature of the hard-to-bend electric wire is larger than that of the easy-to-bend electric wire, and accordingly, a large arrangement space is required.
　本例では、電力線３２は、グランド線３６及び信号線３４よりも太い。このため、電力線３２は、グランド線３６及び信号線３４よりも曲がりにくい。また、グランド線３６は、信号線３４よりも太い。このため、グランド線３６は、信号線３４よりも曲がりにくい。 In this example, the power line 32 is thicker than the ground line 36 and the signal line 34. Therefore, the power line 32 is less likely to bend than the ground line 36 and the signal line 34 . Also, the ground line 36 is thicker than the signal line 34 . Therefore, the ground line 36 is less likely to bend than the signal line 34 .
　＜端子付き電線＞
　端子２０と電線３０とは、充電コネクタ１０を製造する途中の段階で、圧着によって互いに電気的に接続されつつ固定されて一体化される。このように電線３０と端子２０とが一体化したものは、端子付き電線３８と呼ばれることがある。本例では、電力線３２と中継端子２８とが一体化した端子付き電線３８、信号線３４とシグナル端子２４とが一体化した端子付き電線３８、グランド線３６とグランド端子２６とが一体化した端子付き電線３８とが設けられる。 <Electric wire with terminal>
The terminal 20 and the electric wire 30 are electrically connected to each other by crimping, and are fixed and integrated at a stage in the middle of manufacturing the charging connector 10 . Such an integrated wire 30 and terminal 20 is sometimes called a terminal-equipped wire 38 . In this example, a terminal-attached wire 38 in which the power line 32 and the relay terminal 28 are integrated, a terminal-attached wire 38 in which the signal wire 34 and the signal terminal 24 are integrated, and a terminal in which the ground wire 36 and the ground terminal 26 are integrated An attached wire 38 is provided.
　図５に示すように、端子付き電線３８には、収縮チューブ３９が被せられてもよい。収縮チューブ３９は電線３０と端子２０との接続部分を覆う。これにより、電線３０と端子２０との接続部に水がかかること、及び、被覆３１ｂ内に水が浸入することなどが抑制される。収縮チューブ３９は、例えば、端子２０のうち電線３０が接続される部分よりも前方の部分から、電線３０のうち被覆３１ｂがある部分までを覆う。収縮チューブ３９は、加熱によって収縮する熱収縮チューブ３９である。熱収縮チューブ３９は、加熱される前の大径の状態で端子付き電線３８に被せられる。その後、熱収縮チューブ３９は、加熱されて収縮する際、接続部分の形状に応じた形状になることによって、接続部分に密着することができる。例えば、熱収縮チューブ３９の内面に、ホットメルト接着剤が設けられていてもよい。これにより、ホットメルト接着剤が、熱収縮チューブ３９と端子２０との隙間、及び、熱収縮チューブ３９と電線３０との隙間を埋めることができ、収縮チューブ３９による防水性が高まる。熱収縮チューブ３９の内面に、ホットメルト接着剤が設けられていなくてもよい。端子付き電線３８において、電線３０と端子２０との接続部分に収縮チューブ３９が設けられずに、露出していてもよい。端子付き電線３８において、電線３０と端子２０との接続部分に、収縮チューブ３９に代えて、接着剤などの樹脂が設けられていてもよい。 As shown in FIG. 5, the terminal-equipped electric wire 38 may be covered with a shrinkable tube 39 . A shrinkable tube 39 covers the connecting portion between the electric wire 30 and the terminal 20 . As a result, it is possible to prevent water from splashing on the connecting portion between the electric wire 30 and the terminal 20 and water from entering the coating 31b. The shrinkable tube 39 covers, for example, a portion of the terminal 20 in front of the portion to which the electric wire 30 is connected to a portion of the electric wire 30 having the covering 31b. The shrinkable tube 39 is a heat-shrinkable tube 39 that shrinks when heated. The heat-shrinkable tube 39 is put over the terminal-equipped wire 38 in a large-diameter state before being heated. After that, when the heat-shrinkable tube 39 is heated and shrunk, it assumes a shape corresponding to the shape of the connecting portion, thereby being able to adhere to the connecting portion. For example, the inner surface of the heat-shrinkable tube 39 may be provided with a hot-melt adhesive. As a result, the hot-melt adhesive can fill the gap between the heat-shrinkable tube 39 and the terminal 20 and the gap between the heat-shrinkable tube 39 and the wire 30, and the waterproofness of the shrinkable tube 39 is enhanced. The inner surface of the heat-shrinkable tube 39 may not be provided with hot-melt adhesive. In the electric wire 38 with a terminal, the connecting portion between the electric wire 30 and the terminal 20 may be exposed without the shrinkable tube 39 being provided. In the electric wire 38 with a terminal, a resin such as an adhesive may be provided at the connecting portion between the electric wire 30 and the terminal 20 instead of the shrinkable tube 39 .
　＜サーミスタユニット＞
　サーミスタユニット４０は、電源回路の温度を測定する。急速充電用の充電コネクタ１０において、バッテリを充電するための電源回路には大電流が流れるため、その分、電源回路の温度上昇も大きくなる。サーミスタユニット４０を用いて電源回路の温度が監視されることによって、電源回路の温度が高くなりすぎることを抑制することができる。サーミスタユニット４０は、サーミスタ４２とサーミスタ用電線４４とを有する。本例では、一対のパワー端子２２のそれぞれにサーミスタ４２が取付けられて、一対のパワー端子２２それぞれの温度が測定される。サーミスタ用電線４４の一端部は、サーミスタ４２に接続される。サーミスタ用電線４４の他端部は、電線３０の他端部と同様にグロメット９０から外部に延び出る。充電コネクタ１０が車両に搭載された状態で、サーミスタ用電線４４の他端部は、例えば、ＥＣＵなどに接続される。サーミスタ用電線４４は、電力線３２及びグランド線３６よりも細い。このため、サーミスタ用電線４４は、電力線３２及びグランド線３６よりも曲がりやすい。 <Thermistor unit>
The thermistor unit 40 measures the temperature of the power supply circuit. In the charging connector 10 for rapid charging, a large current flows through the power supply circuit for charging the battery, so the temperature of the power supply circuit rises correspondingly. By monitoring the temperature of the power supply circuit using the thermistor unit 40, it is possible to prevent the temperature of the power supply circuit from becoming too high. The thermistor unit 40 has a thermistor 42 and a thermistor wire 44 . In this example, a thermistor 42 is attached to each of the pair of power terminals 22 to measure the temperature of each of the pair of power terminals 22 . One end of the thermistor electric wire 44 is connected to the thermistor 42 . The other end of the thermistor electric wire 44 extends outside from the grommet 90 like the other end of the electric wire 30 . The other end of the thermistor electric wire 44 is connected to an ECU or the like, for example, while the charging connector 10 is mounted on the vehicle. The thermistor wire 44 is thinner than the power wire 32 and the ground wire 36 . Therefore, the thermistor wire 44 is more likely to bend than the power line 32 and the ground wire 36 .
　＜ハウジング＞
　ハウジング５０は、コネクタ端子２１を所定の位置（外部充電コネクタのコネクタ端子２１と接続可能な位置）に保持する。ハウジング５０は、ハウジング本体５１と、車両取付部５４と、電線押え部５７とを含む。 <Housing>
The housing 50 holds the connector terminal 21 at a predetermined position (a position where it can be connected to the connector terminal 21 of the external charging connector). The housing 50 includes a housing body 51 , a vehicle mounting portion 54 and a wire holding portion 57 .
　ハウジング本体５１にコネクタ端子２１が収容される。ハウジング本体５１は、筒状枠部５２と複数の端子収容部５３とを有する。筒状枠部５２は、複数の端子収容部５３の周りを囲う筒状に形成される。複数の端子収容部５３のそれぞれは、対応するコネクタ端子２１を収容可能な筒状に形成される。端子収容部５３の中間部において、複数の端子収容部５３及び筒状枠部５２が平板状の連結部によってつながっている。ハウジング本体５１の前方にリッドユニット８０が取付けられる。ハウジング本体５１の後方にリテーナ６０が取付けられる。 The connector terminal 21 is accommodated in the housing main body 51 . The housing main body 51 has a tubular frame portion 52 and a plurality of terminal accommodating portions 53 . The tubular frame portion 52 is formed in a tubular shape surrounding the plurality of terminal accommodating portions 53 . Each of the plurality of terminal accommodating portions 53 is formed in a tubular shape capable of accommodating the corresponding connector terminal 21 . In an intermediate portion of the terminal accommodating portion 53, the plurality of terminal accommodating portions 53 and the tubular frame portion 52 are connected by a flat connecting portion. A lid unit 80 is attached to the front of the housing body 51 . A retainer 60 is attached to the rear of the housing body 51 .
　車両取付部５４は、充電コネクタ１０を取付部１００に取付けるための部分である。車両取付部５４は、ハウジング本体５１の中間部において、筒状枠部５２の周囲に突出する板状に形成されている。車両取付部５４は、取付部１００に対して、例えばねじＳなどによって取付けられる。 The vehicle attachment portion 54 is a portion for attaching the charging connector 10 to the attachment portion 100 . The vehicle mounting portion 54 is formed in a plate-like shape protruding around the cylindrical frame portion 52 at the intermediate portion of the housing body 51 . The vehicle attachment portion 54 is attached to the attachment portion 100 by screws S or the like, for example.
　電線押え部５７は、端子２０から延びる電線３０の中間部を押さえる。これにより、電線３０のうち電線押え部５７に押さえられている部分よりも他端部側に生じる振動が、端子２０に伝わりにくくなり、端子２０とハウジング本体５１とが擦れることが抑制される。ハウジング本体５１の後方において、筒状枠部５２からＹ方向にブロック状のアーム５６部が突出する。アーム５６部のうちハウジング本体５１からの突出方向に沿った先端部に電線押え部５７が設けられる。電線押え部５７は、３つ設けられる。３つの電線押え部５７のうち２つの電線押え部５７が２本の電力線３２を押さえ、残りの１つの電線押え部５７が１本のグランド線３６を押さえる。 The wire pressing portion 57 presses the intermediate portion of the wire 30 extending from the terminal 20 . As a result, the vibration generated in the other end side of the wire 30 from the portion held by the wire holding portion 57 is less likely to be transmitted to the terminal 20, and the contact between the terminal 20 and the housing body 51 is suppressed. A block-shaped arm 56 protrudes in the Y direction from the tubular frame 52 behind the housing body 51 . A wire pressing portion 57 is provided at the tip of the arm 56 along the direction of projection from the housing body 51 . Three wire holding portions 57 are provided. Two of the three wire holding portions 57 hold two power lines 32 , and the remaining one wire holding portion 57 holds one ground wire 36 .
　＜リテーナ＞
　リテーナ６０は、ハウジング５０からの端子２０の抜けを抑制する。リテーナ６０は、端子押え部６１と、壁６５、６６とを含む。 <Retainer>
The retainer 60 prevents the terminals 20 from coming off from the housing 50 . The retainer 60 includes a terminal pressing portion 61 and walls 65 and 66 .
　端子押え部６１は、ハウジング５０に収容されたコネクタ端子２１の後方を押さえる。これにより、コネクタ端子２１がハウジング５０から後方に抜けることを抑制する。端子押え部６１は、後方カバー部６２と、複数の突出筒部６３とを含む。 The terminal pressing portion 61 presses the rear of the connector terminal 21 housed in the housing 50 . This prevents the connector terminal 21 from coming out of the housing 50 backward. Terminal pressing portion 61 includes a rear cover portion 62 and a plurality of projecting tubular portions 63 .
　後方カバー部６２は、筒状枠部５２の後方の開口部を塞ぐ。後方カバー部６２には、複数の貫通孔が形成されている。複数の貫通孔は、各端子収容部５３に対応する位置に形成されている。パワー端子２２に対応する貫通孔を通じて、パワー端子２２及び中継端子２８が接触しつつねじ止めされている。中継端子２８は、後方カバーの背面上に配置される。シグナル端子２４及びグランド端子２６に対応する貫通孔から信号線３４及びグランド線３６が引き出されている。 The rear cover portion 62 closes the rear opening of the tubular frame portion 52 . A plurality of through holes are formed in the rear cover portion 62 . A plurality of through holes are formed at positions corresponding to the respective terminal accommodating portions 53 . Through a through hole corresponding to the power terminal 22, the power terminal 22 and the relay terminal 28 are screwed while being in contact with each other. A relay terminal 28 is arranged on the rear surface of the rear cover. A signal line 34 and a ground line 36 are led out from through holes corresponding to the signal terminal 24 and the ground terminal 26 .
　複数の突出筒部６３は、後方カバー部６２から前方（ハウジング５０側）に向けて突出する。複数の突出筒部６３は、各端子収容部５３に対応する位置に形成されている。各突出筒部６３は、各貫通孔と連通する。各突出筒部６３の先端が、対応する端子収容部５３に挿入されて、対応する突出部２３ｃ、２５ｃ、２７ｃを後方から押える。 A plurality of protruding tubular portions 63 protrude forward (to the housing 50 side) from the rear cover portion 62 . A plurality of projecting tubular portions 63 are formed at positions corresponding to the respective terminal accommodating portions 53 . Each projecting tubular portion 63 communicates with each through hole. The tip of each protruding tubular portion 63 is inserted into the corresponding terminal accommodating portion 53 to press the corresponding protruding portions 23c, 25c, 27c from behind.
　壁６５、６６は、後方カバー部６２から後方に向けて突出する。壁６５は、中継端子２８同士を仕切る。また、壁６５は、中継端子２８とシグナル端子２４とを仕切る。壁６５は、中継端子２８の位置決めもしている。中継端子２８のうちパワー端子２２と接続される部分は、壁６５に沿うように配置される。壁６６は、グロメット９０の内部において端子２０収容空間と排水空間とを仕切る。排水口９３から排水空間に侵入した埃等が、端子２０収容空間に達することが抑制される。これにより、埃等が端子２０に付着することが抑制される。 The walls 65 and 66 protrude rearward from the rear cover portion 62 . The wall 65 separates the relay terminals 28 from each other. Also, the wall 65 partitions the relay terminal 28 and the signal terminal 24 . The wall 65 also positions the relay terminal 28 . A portion of the relay terminal 28 that is connected to the power terminal 22 is arranged along the wall 65 . The wall 66 separates the terminal 20 accommodation space and the drainage space inside the grommet 90 . Dust or the like entering the drainage space from the drainage port 93 is suppressed from reaching the terminal 20 housing space. As a result, adhesion of dust or the like to the terminal 20 is suppressed.
　ハウジング５０及びリテーナ６０には、係止部が設けられている。本例では、係止部として、ハウジング５０に形成された係止突起とリテーナ６０に形成された係止片とが設けられている。係止片が係止突起に係止することによって、ハウジング５０及びリテーナ６０が、互いに取付けられた状態に維持される。 A locking portion is provided on the housing 50 and the retainer 60 . In this example, a locking protrusion formed on the housing 50 and a locking piece formed on the retainer 60 are provided as the locking portions. The housing 50 and the retainer 60 are kept attached to each other by the engagement of the engagement pieces with the engagement projections.
　＜電線カバー＞
　電線カバー７０は、電線押え部５７に取付けられる。電線カバー７０は電線３０が電線押え部５７から抜けることを抑制する。電線カバー７０及び電線押え部５７によって、電線３０の周囲全体が覆われる。本実施形態では、２つの電線カバー７０が設けられる。２つの電線カバー７０のうち一方の電線カバー７０は、２本の電力線３２を押さえる。２つの電線カバー７０のうち他方の電線カバー７０は、１本のグランド線３６を押さえる。 <Electric wire cover>
The wire cover 70 is attached to the wire holding portion 57 . The wire cover 70 prevents the wire 30 from coming off the wire holding portion 57 . The entire periphery of the wire 30 is covered by the wire cover 70 and the wire holding portion 57 . In this embodiment, two wire covers 70 are provided. One of the two wire covers 70 holds down the two power lines 32 . The other wire cover 70 of the two wire covers 70 holds down one ground wire 36 .
　＜リッドユニット＞
　リッドユニット８０は、筒状枠部５２の先端側に開閉可能に取付けられる。リッドユニット８０が開くことによって、ハウジング本体５１の接続口が露出する。これにより、外部充電コネクタが筒状枠部５２に挿し込まれて当該充電コネクタ１０と外部充電コネクタとが接続可能となる。充電後に外部充電コネクタが筒状枠部５２から抜かれて、リッドユニット８０が閉じることによって、ハウジング本体５１の接続口がリッドユニット８０によって閉鎖される。リッドユニット８０は、リッド８２と、ヒンジユニット８４と、ロックユニット８６とを有する。リッド８２は、ヒンジユニット８４を介してハウジング本体５１に開閉可能に取り付けられる。ロックユニット８６は、リッド８２を閉じた状態に維持する。充電作業時に、作業者は、ロックユニット８６を操作して、リッド８２を開くことができる。 <Lid unit>
The lid unit 80 is attached to the tip side of the cylindrical frame portion 52 so as to be openable and closable. The connection port of the housing body 51 is exposed by opening the lid unit 80 . As a result, the external charging connector is inserted into the tubular frame portion 52 and the charging connector 10 and the external charging connector can be connected. After charging, the external charging connector is removed from the cylindrical frame portion 52 and the lid unit 80 is closed, whereby the connection port of the housing body 51 is closed by the lid unit 80 . The lid unit 80 has a lid 82 , a hinge unit 84 and a lock unit 86 . The lid 82 is attached to the housing body 51 via a hinge unit 84 so as to be openable and closable. A lock unit 86 keeps the lid 82 closed. An operator can operate the lock unit 86 to open the lid 82 during the charging operation.
　＜グロメット＞
　グロメット９０は、ハウジング５０及びリテーナ６０を覆う。グロメット９０は、第１保護部９１と、第２保護部９４とを含む。第１保護部９１は、ハウジング本体５１の後端部とリテーナ６０とを覆う。第２保護部９４は、電線押え部５７を覆う。グロメット９０は、例えば、ＥＰＤＭなどのエラストマ製である。 <Grommet>
Grommet 90 covers housing 50 and retainer 60 . Grommet 90 includes a first protector 91 and a second protector 94 . The first protection portion 91 covers the rear end portion of the housing body 51 and the retainer 60 . The second protection portion 94 covers the wire holding portion 57 . Grommet 90 is made of an elastomer such as EPDM, for example.
　第１保護部９１には、ハウジング引出口９２及び排水口９３が形成されている。ハウジング引出口９２を通じてハウジング本体５１の前端部がグロメット９０の外部に延び出る。排水口９３は、充電コネクタ１０の内部に浸入する水を外部に排水するための開口部である。かかる水は、例えば、リッドユニット８０が開いたときに、ハウジング本体５１の開口部から浸入することなどが想定される。ハウジング引出口９２の外面には、結束バンド９８が取付けられている。グロメット９０は、結束バンド９８によってハウジング５０に取付けられている。 A housing drawer port 92 and a drain port 93 are formed in the first protection portion 91 . The front end of the housing body 51 extends outside the grommet 90 through the housing outlet 92 . Drain port 93 is an opening for draining water that has entered charging connector 10 to the outside. Such water is assumed to enter through the opening of the housing body 51 when the lid unit 80 is opened, for example. A binding band 98 is attached to the outer surface of the housing outlet 92 . Grommet 90 is attached to housing 50 by a tie band 98 .
　第２保護部９４には、電線引出口９５が形成されている。電線引出口９５を通じて電線３０の他端部がグロメット９０の外部に延び出る。１つのグロメット９０に３つの電線引出口９５が設けられている。３つの電線引出口９５のうち２つの電線引出口９５は、２つの電力線３２用に設けられる。２つの電線引出口９５それぞれに１本の電力線３２が通されている。３つの電線引出口９５のうち残りの１つの電線引出口９５に、信号線３４、グランド線３６、サーミスタ用電線４４がまとめて通されている。 A wire outlet 95 is formed in the second protection portion 94 . The other end of the wire 30 extends outside the grommet 90 through the wire outlet 95 . One grommet 90 is provided with three wire outlets 95 . Two of the three wire outlets 95 are provided for two power lines 32 . One power line 32 is passed through each of the two wire outlets 95 . The signal wire 34 , the ground wire 36 , and the thermistor wire 44 are collectively passed through the remaining one wire outlet 95 out of the three wire outlets 95 .
　＜充電コネクタにおける電線の経路＞
　電力線３２は、中継端子２８と接続される一端部から他端部に向けて、グロメット９０内を一直線状に延び、引出口を通じてグロメット９０の外部に延び出ている。従って、電力線３２の一端部は、貫通孔内に挿入されない。 <Wire path in charging connector>
The power line 32 extends straight through the grommet 90 from one end connected to the relay terminal 28 to the other end, and extends outside the grommet 90 through the outlet. Therefore, one end of the power line 32 is not inserted into the through hole.
　２つの電力線３２は、Ｚ方向に並んでグロメット９０内を延びる。２つのパワー端子２２は、Ｙ方向に並んでハウジング本体５１に収容される。２つの電力線３２が並ぶ方向と、２つのパワー端子２２が並ぶ方向の違いは、中継端子２８によって吸収されている。より詳細には、２つの中継端子２８はそれぞれ板部上に配置される。２つの中継端子２８のうち中継端子２８Ａは、引出口に近いパワー端子２２に接続され、中継端子２８Ｂは、引出口から遠いパワー端子２２に接続される。中継端子２８Ａ及び中継端子２８Ｂは、パワー端子２２と接続される部分においてＹ方向に並び、電線３０と接続される部分においてＺ方向に並ぶ。中継端子２８Ａは、パワー端子２２と接続される部分と、電力線３２と接続される部分との間で、板部に沿って一直線状に延びている。中継端子２８Ｂは、パワー端子２２と接続される部分から電力線３２と接続される部分に向かう途中で、板部から離れるように折り曲がっている。 The two power lines 32 extend in the grommet 90 side by side in the Z direction. The two power terminals 22 are housed in the housing body 51 side by side in the Y direction. The difference between the direction in which the two power lines 32 are arranged and the direction in which the two power terminals 22 are arranged is absorbed by the relay terminal 28 . More specifically, each of the two relay terminals 28 is arranged on the plate portion. Of the two relay terminals 28, the relay terminal 28A is connected to the power terminal 22 closer to the outlet, and the relay terminal 28B is connected to the power terminal 22 farther from the outlet. The relay terminals 28</b>A and 28</b>B are aligned in the Y direction at the portions connected to the power terminals 22 , and aligned in the Z direction at the portions connected to the electric wires 30 . The relay terminal 28A extends linearly along the plate portion between the portion connected to the power terminal 22 and the portion connected to the power line 32 . The relay terminal 28B is bent away from the plate portion on the way from the portion connected to the power terminal 22 to the portion connected to the power line 32 .
　信号線３４の一端部は、キャビティ内に挿入される。信号線３４の他端部は、貫通孔から延び出て、グロメット９０内で曲がりつつ、グロメット９０の引出口に向かう。複数の信号線３４のうち信号線３４Ａは、パワー端子２２よりも上方に位置するシグナル端子２４と接続され、信号線３４Ｂは、パワー端子２２よりも下方に位置するシグナル端子２４と接続される。信号線３４Ａは、貫通孔から延び出た後、一対の電力線３２の間を通りつつ、信号線３４Ｂと合流して、Ｙ方向に延びる。 One end of the signal line 34 is inserted into the cavity. The other end of the signal line 34 extends from the through hole and bends inside the grommet 90 toward the outlet of the grommet 90 . Of the plurality of signal lines 34 , the signal line 34A is connected to the signal terminal 24 located above the power terminal 22 , and the signal line 34B is connected to the signal terminal 24 located below the power terminal 22 . After extending from the through hole, the signal line 34A passes between the pair of power lines 32 and merges with the signal line 34B to extend in the Y direction.
　グランド線３６の一端部は、キャビティ内に挿入される。グランド線３６は、一端部から他端部に向けて、貫通孔から延び出て、グロメット９０内で曲がりつつ、信号線３４と共にグロメット９０の引出口に向かう。上記のように、グランド線３６は信号線３４よりも曲がりにくいため、信号線３４及びグランド線３６がＸ方向からＹ方向に向けて曲がる部分において、信号線３４の曲率半径よりもグランド線３６の曲率半径が大きくなりやすい。グランド線３６の他端部を電線３０押さえ部及び電線カバー７０によって押さえることによって、グランド線３６がグロメット９０内で膨らみすぎることを抑制している。 One end of the ground wire 36 is inserted into the cavity. The ground line 36 extends from one end to the other end through the through hole, bends inside the grommet 90 , and heads toward the outlet of the grommet 90 together with the signal line 34 . As described above, since the ground line 36 is less likely to bend than the signal line 34, the ground line 36 is bent more than the signal line 34 at the portion where the signal line 34 and the ground line 36 are bent from the X direction to the Y direction. The radius of curvature tends to be large. By holding the other end of the ground wire 36 with the wire 30 holding portion and the wire cover 70 , the ground wire 36 is prevented from bulging excessively within the grommet 90 .
　サーミスタ４２は、パワー端子２２と共にハウジング本体５１に収容される。従って、サーミスタ用電線４４の一端部もハウジング本体５１に収容される。サーミスタ用電線４４の他端部は、貫通孔を通じて、板部の外側に延び出て、グロメット９０内で曲がりつつ、グロメット９０の引出口に向かう。サーミスタ用電線４４は、貫通孔のうち端子付き電線３８の挿入に用いられる部分を通る。サーミスタ用電線４４は、一対の電力線３２の間を通りつつ、信号線３４と共にＹ方向に延びる。 The thermistor 42 is housed in the housing main body 51 together with the power terminal 22 . Accordingly, one end of the thermistor electric wire 44 is also accommodated in the housing main body 51 . The other end of the thermistor electric wire 44 extends through the through hole to the outside of the plate portion, bends inside the grommet 90 , and heads toward the outlet of the grommet 90 . The thermistor electric wire 44 passes through a portion of the through hole that is used for inserting the terminal-equipped electric wire 38 . The thermistor electric wire 44 extends in the Y direction together with the signal line 34 while passing between the pair of power lines 32 .
　＜リッド及びヒンジユニット＞
　図８から図１０をさらに参照しつつ、リッド８２及びヒンジユニット８４について説明する。図８はリッド８２及びヒンジユニット８４を示す図である。図８はリッド８２の内面から見た図である。図９は閉状態のリッド８２を示す図である。図１０は開状態のリッド８２を示す図である。図９及び図１０に示す断面は図４のＸＩ－ＸＩ線に沿った断面に相当する。 <Lid and hinge unit>
The lid 82 and the hinge unit 84 will be described with further reference to FIGS. 8 to 10. FIG. FIG. 8 is a diagram showing the lid 82 and the hinge unit 84. FIG. FIG. 8 is a view of the lid 82 viewed from the inner surface. FIG. 9 shows the lid 82 in a closed state. FIG. 10 shows the lid 82 in an open state. The cross sections shown in FIGS. 9 and 10 correspond to cross sections taken along line XI--XI in FIG.
　リッド８２は、筒状枠部５２の先端側に開閉可能に取付けられている。リッド８２は、被支持部８２ａと被係止部８２ｂとリッド本体８３とを有する。被支持部８２ａは、ハウジング５０に取付けられる部分である。被係止部８２ｂは、ロックユニット８６が係止する部分である。リッド本体８３は、筒状枠部５２の端面を覆う部分である。被支持部８２ａ及び被係止部８２ｂは、リッド本体８３よりも外周側に突出する。被支持部８２ａ及び被係止部８２ｂはリッド本体８３の外縁から互いに逆向きに延びる。例えば、リッド８２は、樹脂材料による金型一体成形品である。リッド８２の樹脂材料は、例えば、ハウジング５０の樹脂材料と同じ材料であってもよい。 The lid 82 is attached to the tip side of the cylindrical frame portion 52 so as to be openable and closable. The lid 82 has a supported portion 82 a , a locked portion 82 b and a lid body 83 . The supported portion 82 a is a portion attached to the housing 50 . The locked portion 82b is a portion to which the lock unit 86 locks. The lid body 83 is a portion that covers the end face of the tubular frame portion 52 . The supported portion 82 a and the locked portion 82 b protrude outward from the lid body 83 . The supported portion 82a and the locked portion 82b extend from the outer edge of the lid body 83 in opposite directions. For example, the lid 82 is an integrally molded product made of resin material. The resin material of the lid 82 may be, for example, the same material as the resin material of the housing 50 .
　リッド本体８３の内面８３ａにはシール部材８９が設けられる。シール部材８９は、リッド８２が閉状態のときに筒状枠部５２の端面と接触する。シール部材８９は、リッド８２とは別に成形された部材である。シール部材８９は、リッド８２及びハウジング５０よりも高い弾性を有する。シール部材８９は、例えば、エラストマ製であってもよい。リッド８２が閉状態でシール部材８９がリッド本体８３の内面８３ａと筒状枠部５２の端面とに挟まれて圧縮状態となる。これにより、リッド本体８３の内面８３ａと筒状枠部５２の端面との隙間のシール性が高まる。 A seal member 89 is provided on the inner surface 83 a of the lid body 83 . The seal member 89 contacts the end surface of the cylindrical frame portion 52 when the lid 82 is closed. The seal member 89 is a member molded separately from the lid 82 . The seal member 89 has higher elasticity than the lid 82 and the housing 50 . The sealing member 89 may be made of elastomer, for example. When the lid 82 is closed, the seal member 89 is sandwiched between the inner surface 83a of the lid body 83 and the end surface of the cylindrical frame portion 52 and is compressed. As a result, the sealability of the gap between the inner surface 83a of the lid body 83 and the end surface of the tubular frame portion 52 is enhanced.
　シール部材８９は、環状に形成されている。シール部材８９は、筒状枠部５２の端面に対応する形状とされる。シール部材８９は、リッド８２に取付けられている。かかる取付け態様は特に限定されるものではなく、適宜設定可能である。例えば、シール部材８９は、接着剤又は両面粘着テープなどによってリッド８２に貼付けられていてもよい。 The seal member 89 is formed in an annular shape. The seal member 89 has a shape corresponding to the end surface of the tubular frame portion 52 . A seal member 89 is attached to the lid 82 . Such attachment mode is not particularly limited, and can be set as appropriate. For example, the seal member 89 may be attached to the lid 82 with an adhesive, double-sided adhesive tape, or the like.
　リッド本体８３の内面８３ａのうちシール部材８９が取付けられる面が取付面８３ｂとされる。リッド本体８３の内面８３ａにおいて、取付面８３ｂの外側に外枠部８３ｃが設けられる。外枠部８３ｃは、シール部材８９の外縁に沿って延在する。これにより、シール部材８９の外縁の位置が規制される。外枠部８３ｃは、被支持部８２ａ及び被係止部８２ｂによって途切れている。 A surface of the inner surface 83a of the lid body 83 to which the seal member 89 is attached is a mounting surface 83b. On the inner surface 83a of the lid body 83, an outer frame portion 83c is provided outside the mounting surface 83b. The outer frame portion 83 c extends along the outer edge of the seal member 89 . Thereby, the position of the outer edge of the seal member 89 is regulated. The outer frame portion 83c is interrupted by the supported portion 82a and the locked portion 82b.
　リッド本体８３の内面８３ａにおいて、取付面８３ｂの内側に第１リブ８３ｄが設けられる。第１リブ８３ｄは、環状に形成されている。第１リブ８３ｄは、シール部材８９の内側に沿って延びる。リッド本体８３の内面８３ａにおいて、取付面８３ｂは、外枠部８３ｃ及び第１リブ８３ｄに囲まれる凹部の底となっている。第１リブ８３ｄは、シール部材８９の内縁に対応する形状とされる。第１リブ８３ｄは、シール部材８９の内縁と同じかそれよりもわずかに小さく形成されるとよい。筒状枠部５２の端面、シール部材８９、及び第１リブ８３ｄは、それぞれ半円よりも大きな円弧部分と円弧部分をつなぐ直線部分とを有する。第１リブ８３ｄの内側に第２リブ８３ｅ及び第３リブ８３ｆが設けられる。 On the inner surface 83a of the lid body 83, a first rib 83d is provided inside the mounting surface 83b. The first rib 83d is formed in an annular shape. The first rib 83 d extends along the inner side of the seal member 89 . On the inner surface 83a of the lid body 83, the mounting surface 83b is the bottom of a recess surrounded by the outer frame portion 83c and the first ribs 83d. The first rib 83 d has a shape corresponding to the inner edge of the seal member 89 . The first rib 83d is preferably formed to be the same as or slightly smaller than the inner edge of the seal member 89. As shown in FIG. The end surface of the cylindrical frame portion 52, the seal member 89, and the first rib 83d each have an arc portion larger than a semicircle and a straight portion connecting the arc portions. A second rib 83e and a third rib 83f are provided inside the first rib 83d.
　第２リブ８３ｅは、リッド８２の中央部から第１リブ８３ｄに向かって放射状に延びる。第２リブ８３ｅは複数（図８に示す例では８つ）設けられる。複数の第２リブ８３ｅは、中央部の周りに等間隔で設けられてもよい。 The second rib 83e radially extends from the central portion of the lid 82 toward the first rib 83d. A plurality of second ribs 83e (eight in the example shown in FIG. 8) are provided. The plurality of second ribs 83e may be evenly spaced around the central portion.
　第３リブ８３ｆは、第１リブ８３ｄよりも小さい環状に形成されている。第３リブ８３ｆは、円形状であってもよい。複数の第２リブ８３ｅは、第３リブ８３ｆを起点として第１リブ８３ｄに向けて延びている。第２リブ８３ｅの一端部は第３リブ８３ｆよりリッド８２の中央部に延びていない。第２リブ８３ｅの一端部は第３リブ８３ｆで止まっている。第２リブ８３ｅは、第１リブ８３ｄと第３リブ８３ｆとをつなぐ。第２リブ８３ｅの他端部は第１リブ８３ｄよりリッド８２の外側に延びていない。第２リブ８３ｅの他端部は第１リブ８３ｄで止まっている。 The third rib 83f is formed in an annular shape smaller than the first rib 83d. The third rib 83f may be circular. The plurality of second ribs 83e extend from the third rib 83f toward the first rib 83d. One end of the second rib 83e does not extend to the central portion of the lid 82 from the third rib 83f. One end of the second rib 83e stops at the third rib 83f. The second rib 83e connects the first rib 83d and the third rib 83f. The other end of the second rib 83e does not extend outside the lid 82 beyond the first rib 83d. The other end of the second rib 83e stops at the first rib 83d.
　第３リブ８３ｆの大きさ（直径）は、複数の第２リブ８３ｅの一端部を互いに離間させることができる大きさであると良い。隣り合う第２リブ８３ｅは互いに交差せずに、第３リブ８３ｆを介してつながっている。これにより、複数の第２リブ８３ｅの一端部がリッド８２の中央部における一点（リッド８２の中心）に集中することが抑制される。第３リブ８３ｆの直径は、第２リブ８３ｅの長さ寸法よりも短くてもよい。 The size (diameter) of the third rib 83f is preferably large enough to separate one ends of the plurality of second ribs 83e from each other. Adjacent second ribs 83e are connected via third ribs 83f without intersecting each other. This prevents the one end portions of the plurality of second ribs 83 e from concentrating on one point in the central portion of the lid 82 (the center of the lid 82 ). The diameter of the third rib 83f may be shorter than the length dimension of the second rib 83e.
　図９に示すように、被係止部８２ｂの外面８２ｃは、リッド本体８３の外面８３ｇよりも筒状枠部５２側に低くなっている。これにより、筒状枠部５２の端面からのロックユニット８６の突出寸法が小さくなり、パネル１０２と車体側カバー１０６との間隔を小さくできる。 As shown in FIG. 9, the outer surface 82c of the locked portion 82b is lower toward the cylindrical frame portion 52 than the outer surface 83g of the lid body 83. As shown in FIG. As a result, the length of protrusion of the lock unit 86 from the end face of the tubular frame portion 52 is reduced, and the distance between the panel 102 and the vehicle body side cover 106 can be reduced.
　また被係止部８２ｂにはガイド部８２ｄが設けられている。ガイド部８２ｄは、被係止部８２ｂの下面（筒状枠部５２側の面）から上面に向けて外向きに傾斜する傾斜面である。 A guide portion 82d is provided in the locked portion 82b. The guide portion 82d is an inclined surface that slopes outward from the lower surface (the surface on the cylindrical frame portion 52 side) of the locked portion 82b toward the upper surface.
　ヒンジユニット８４は、軸部８４ａと付勢部材８４ｂとを有する。軸部８４ａは、リッド側軸部の一例である。軸部８４ａは、被支持部８２ａを貫通する。付勢部材８４ｂは軸部８４ａに支持される。リッド８２は、ヒンジユニット８４を介してハウジング５０のリッド取付部５８に取付けられる。リッド取付部５８は、一対の軸受部を有する。軸部８４ａの一端部が一対の軸受部の一方に支持され、軸部８４ａの他端部が一対の軸受部の他方に支持される。被支持部８２ａ及び付勢部材８４ｂは、一対の軸受部の間に収容される。 The hinge unit 84 has a shaft portion 84a and a biasing member 84b. The shaft portion 84a is an example of a lid-side shaft portion. The shaft portion 84a passes through the supported portion 82a. The biasing member 84b is supported by the shaft portion 84a. The lid 82 is attached to the lid attachment portion 58 of the housing 50 via the hinge unit 84 . The lid attachment portion 58 has a pair of bearing portions. One end portion of the shaft portion 84a is supported by one of the pair of bearing portions, and the other end portion of the shaft portion 84a is supported by the other of the pair of bearing portions. The supported portion 82a and the biasing member 84b are housed between a pair of bearing portions.
　リッド８２は、軸部８４ａを介してハウジング５０に回動可能に取付けられる。なお、本例では、軸部８４ａは、リッド取付部５８に圧入されるなどして回動不能に支持され、リッド８２と軸部８４ａとが回動可能とされる。リッド８２と軸部８４ａとが圧入されるなどして回動不能に支持され、軸部８４ａがリッド取付部５８に回動可能に支持されてもよい。 The lid 82 is rotatably attached to the housing 50 via the shaft portion 84a. In this example, the shaft portion 84a is press-fitted into the lid mounting portion 58 and supported so as not to be rotatable, so that the lid 82 and the shaft portion 84a are rotatable. The lid 82 and the shaft portion 84a may be press-fitted to be non-rotatably supported, and the shaft portion 84a may be rotatably supported by the lid mounting portion 58 .
　付勢部材８４ｂは、リッド側付勢部材の一例である。付勢部材８４ｂは、リッド８２を回動方向に沿って開状態に付勢する。付勢部材８４ｂは、ばねなどの弾性部材であってもよい。図８に示す例では、付勢部材８４ｂとしてねじりコイルバネが用いられている。なお、ハウジング５０に外部充電コネクタが嵌合可能な程度にリッド８２が開いた状態で、規制部によって、リッド８２がそれ以上開くことが規制されてもよい。例えば、被支持部８２ａに筒状枠部５２の外周面と接触する規制部が設けられて、リッド８２の開きが規制されてもよい。 The biasing member 84b is an example of a lid-side biasing member. The biasing member 84b biases the lid 82 to the open state along the rotation direction. The biasing member 84b may be an elastic member such as a spring. In the example shown in FIG. 8, a torsion coil spring is used as the biasing member 84b. In addition, when the lid 82 is opened to the extent that the external charging connector can be fitted to the housing 50 , the lid 82 may be restricted from opening any further by the restricting portion. For example, the supported portion 82a may be provided with a restricting portion that contacts the outer peripheral surface of the cylindrical frame portion 52 to restrict the lid 82 from opening.
　またリッド８２は、ダンパ８５を介してハウジング５０のリッド取付部５８に取付けられる。ダンパ８５は、付勢部材８４ｂによるリッド８２の開く勢いを規制する。ダンパ８５は、被支持部８２ａに収容されている。被支持部８２ａにはダンパ収容部が設けられる。被支持部８２ａは一対の軸受部を有する。被支持部８２ａにおける一対の軸受部の一方にダンパ収容部が設けられる。ダンパ８５には、軸部８４ａが通される。ダンパ収容部は、軸部８４ａの延在方向に沿って、付勢部材８４ｂの隣に設けられる。 Also, the lid 82 is attached to the lid attachment portion 58 of the housing 50 via a damper 85 . The damper 85 restricts the opening momentum of the lid 82 by the biasing member 84b. The damper 85 is accommodated in the supported portion 82a. A damper accommodating portion is provided in the supported portion 82a. The supported portion 82a has a pair of bearing portions. A damper accommodating portion is provided in one of the pair of bearing portions in the supported portion 82a. A shaft portion 84 a is passed through the damper 85 . The damper housing portion is provided next to the biasing member 84b along the extending direction of the shaft portion 84a.

　図１１及び図１２をさらに参照しつつ、ロックユニット８６について説明する。図１１はロックユニット８６を示す斜視図である。図１２は図４の領域ＸＩＩの拡大図である。 <Lock unit>
The lock unit 86 will be described with further reference to FIGS. 11 and 12. FIG. FIG. 11 is a perspective view showing the lock unit 86. FIG. FIG. 12 is an enlarged view of area XII in FIG.
　ロックユニット８６は、係止部材８７と、ヒンジユニット８８とを有する。係止部材８７は、リッド８２に係止する。係止部材８７は、ヒンジユニット８８を介してハウジング５０に回動可能に取付けられる。係止部材８７は、被支持部８７ａと、係止部８７ｂと、突出部８７ｃとを有する。 The lock unit 86 has a locking member 87 and a hinge unit 88. The locking member 87 locks onto the lid 82 . The locking member 87 is rotatably attached to the housing 50 via a hinge unit 88 . The locking member 87 has a supported portion 87a, a locking portion 87b, and a projecting portion 87c.
　被支持部８７ａは、ハウジング５０に取付けられる。被支持部８７ａは、ヒンジユニット８８における軸部８８ａに支持される。被支持部８７ａは一対の軸受部を有する。各軸受部をヒンジユニット８８における軸部８８ａが貫通する。係止部材８７は、軸部８８ａを介して筒状枠部５２に対して第１位置と第２位置との間で回動可能に支持されている。図９において、係止部材８７は第１位置にある。図１０において、係止部材８７は第２位置にある。 The supported portion 87 a is attached to the housing 50 . The supported portion 87 a is supported by the shaft portion 88 a of the hinge unit 88 . The supported portion 87a has a pair of bearing portions. A shaft portion 88a of the hinge unit 88 passes through each bearing portion. The locking member 87 is rotatably supported between a first position and a second position with respect to the tubular frame portion 52 via a shaft portion 88a. In FIG. 9, locking member 87 is in the first position. In FIG. 10, locking member 87 is in the second position.
　係止部８７ｂは、被支持部８７ａから径方向外側に突出する。図９に示すように、係止部材８７が第１位置にある場合において、係止部８７ｂは閉状態のリッド８２の被係止部８２ｂに係止可能である。図１０に示すように、係止部材８７が第１位置から第２位置に回動して、係止部８７ｂとリッド８２の被係止部８２ｂとの係止状態が解消される。 The locking portion 87b protrudes radially outward from the supported portion 87a. As shown in FIG. 9, when the locking member 87 is at the first position, the locking portion 87b can be locked to the locked portion 82b of the lid 82 in the closed state. As shown in FIG. 10, the locking member 87 rotates from the first position to the second position, and the locked state between the locking portion 87b and the locked portion 82b of the lid 82 is released.
　係止部８７ｂは、被支持部８７ａから径方向外側に突出する第１部分と、第１部分の先端から第１部分の延在方向と交差する方向に突出する第２部分とを有する。第２部分のうち軸部側を向く面が被係止部８２ｂの上方を押さえる。 The engaging portion 87b has a first portion protruding radially outward from the supported portion 87a and a second portion protruding from the tip of the first portion in a direction intersecting the extending direction of the first portion. A surface of the second portion facing the shaft side presses the upper side of the engaged portion 82b.
　係止部８７ｂの天面８７ｄには、ガイド部８７ｅと凸部８７ｆとが設けられる。ガイド部８７ｅは、天面８７ｄから下面に向けて外向きに傾斜する傾斜面である。 A guide portion 87e and a convex portion 87f are provided on the top surface 87d of the locking portion 87b. The guide portion 87e is an inclined surface that slopes outward from the top surface 87d toward the bottom surface.
　凸部８７ｆは、軸部８８ａの延在方向に沿って延びる。本例では、凸部８７ｆは、一条のみ設けられている。凸部８７ｆは、天面８７ｄのうちリッド８２から遠い側の端部に設けられている。凸部８７ｆは、係止部８７ｂの第１部分の一部が延在方向に延長している。 The convex portion 87f extends along the extending direction of the shaft portion 88a. In this example, only one protrusion 87f is provided. The convex portion 87f is provided at the end of the top surface 87d farther from the lid 82 . A portion of the first portion of the locking portion 87b extends in the extending direction of the convex portion 87f.
　突出部８７ｃは、リッド８２とハウジング５０とが固着していた場合に、リッド８２を押す部分である。突出部８７ｃは、被支持部８７ａから径方向外側に突出する。筒状枠部５２の径方向において、突出部８７ｃは、係止部８７ｂよりも筒状枠部５２側に突出する。図９に示すように、係止部材８７が第１位置にある場合において、突出部８７ｃはＸ方向に沿って筒状枠部５２の先端より内側に位置する。図１０に示すように、係止部材８７が第１位置から第２位置に回動して、突出部８７ｃがＸ方向に沿って筒状枠部５２の先端より外側に位置する。 The projecting portion 87c is a portion that pushes the lid 82 when the lid 82 and the housing 50 are fixed. The protruding portion 87c protrudes radially outward from the supported portion 87a. In the radial direction of the cylindrical frame portion 52, the protruding portion 87c protrudes toward the cylindrical frame portion 52 side more than the engaging portion 87b. As shown in FIG. 9, when the locking member 87 is at the first position, the projecting portion 87c is located inside the tip of the cylindrical frame portion 52 along the X direction. As shown in FIG. 10, the locking member 87 rotates from the first position to the second position, and the projecting portion 87c is positioned outside the tip of the cylindrical frame portion 52 along the X direction.
　突出部８７ｃは、係止部８７ｂが被係止部８２ｂから離れた後に、被係止部８２ｂと接触するように構成されてもよい。例えば、係止部８７ｂが被係止部８２ｂからちょうど離れた位置を係止部材８７の第３位置とする。第３位置は第１位置と第２位置との間にあり、係止部材８７は、第３位置から第２位置へ向けてさらに回動可能とされる。突出部８７ｃは、第３位置で被係止部８２ｂと接触するように構成されてもよい。突出部８７ｃは、第３位置と第２位置との間で、被係止部８２ｂと接触するように構成されてもよい。 The projecting portion 87c may be configured to come into contact with the locked portion 82b after the locking portion 87b is separated from the locked portion 82b. For example, the third position of the locking member 87 is the position where the locking portion 87b is just separated from the locked portion 82b. The third position is between the first position and the second position, and the locking member 87 can be further rotated from the third position to the second position. The projecting portion 87c may be configured to contact the locked portion 82b at the third position. The projecting portion 87c may be configured to contact the engaged portion 82b between the third position and the second position.
　突出部８７ｃのうち上面がリッド８２を押す押圧面とされる。突出部８７ｃの上面は、係止部材８７が第１位置にある状態で、筒状枠部５２の外側から筒状枠部５２側に向かって傾斜する傾斜面であってもよい。これにより、係止部８７ｂが被係止部８２ｂに係止した状態で、突出部８７ｃが被係止部８２ｂと接触することが抑制される。突出部８７ｃには、押圧凸部８７ｇが設けられる。押圧凸部８７ｇは、突出部８７ｃの押圧面のうち中央部分に設けられる。押圧凸部８７ｇは、押圧面の他の部分よりも厚肉かつ外側に凸となっている。これにより、突出部８７ｃの剛性が高められている。 The upper surface of the projecting portion 87c serves as a pressing surface for pressing the lid 82. The upper surface of the projecting portion 87c may be an inclined surface that inclines from the outside of the tubular frame portion 52 toward the tubular frame portion 52 when the locking member 87 is in the first position. This prevents the projecting portion 87c from coming into contact with the engaged portion 82b while the engaging portion 87b is engaged with the engaged portion 82b. A pressing convex portion 87g is provided on the projecting portion 87c. The pressing convex portion 87g is provided in the central portion of the pressing surface of the projecting portion 87c. The pressing convex portion 87g is thicker than other portions of the pressing surface and protrudes outward. Thereby, the rigidity of the projecting portion 87c is enhanced.
　突出部８７ｃは、被係止部８２ｂのうちガイド部８２ｄよりもリッド本体８３側に接触してもよい。これにより、突出部８７ｃが被係止部８２ｂを押す力が、ハウジング５０に固着しているリッド８２を開く力として作用しやすい。 The projecting portion 87c may contact the lid main body 83 side of the locked portion 82b rather than the guide portion 82d. As a result, the force of the protruding portion 87 c pushing against the locked portion 82 b tends to act as a force to open the lid 82 fixed to the housing 50 .
　係止部材８７は、スペーサ部８７ｈをさらに有する。スペーサ部８７ｈは、被支持部８７ａの外面から軸部８８ａの延在方向に沿ってロック取付部５９の軸受部に突出する。スペーサ部８７ｈの周囲の位置において、被支持部８７ａの外面とロック取付部５９の軸受部の内面とが互いに離間しつつ対向している。スペーサ部８７ｈは、係止部材８７とロック取付部５９との接触面積を小さくする。なお、ロック取付部５９の軸受部の内面には、スペーサ部８７ｈのような凸となる部分が設けられていない。ロック取付部５９の軸受部の内面にも、スペーサ部８７ｈのような凸となる部分が設けられていてもよい。 The locking member 87 further has a spacer portion 87h. The spacer portion 87h protrudes from the outer surface of the supported portion 87a to the bearing portion of the lock attachment portion 59 along the extending direction of the shaft portion 88a. At a position around the spacer portion 87h, the outer surface of the supported portion 87a and the inner surface of the bearing portion of the lock mounting portion 59 face each other while being separated from each other. The spacer portion 87 h reduces the contact area between the locking member 87 and the lock mounting portion 59 . Note that the inner surface of the bearing portion of the lock mounting portion 59 is not provided with a convex portion such as the spacer portion 87h. The inner surface of the bearing portion of the lock attachment portion 59 may also be provided with a convex portion like the spacer portion 87h.
　係止部材８７は、回動規制部８７ｉをさらに有する。回動規制部８７ｉは、係止部材８７が回動方向に沿って第２位置よりもさらに回動することを規制する。回動規制部８７ｉは、被支持部８７ａから径方向外側に突出する。回動規制部８７ｉは、突出部８７ｃよりも車内側に突出する。第２位置において、回動規制部８７ｉが筒状枠部５２の外周面に接触することによって、係止部材８７が回動方向に沿って第２位置よりもさらに回動することが規制される。 The locking member 87 further has a rotation restricting portion 87i. The rotation restricting portion 87i restricts the locking member 87 from rotating further than the second position along the rotation direction. The rotation restricting portion 87i protrudes radially outward from the supported portion 87a. The rotation restricting portion 87i protrudes further toward the vehicle interior than the protruding portion 87c. At the second position, the rotation restricting portion 87i contacts the outer peripheral surface of the cylindrical frame portion 52, thereby restricting the locking member 87 from rotating further than the second position along the rotation direction. .
　ヒンジユニット８８は、軸部８８ａと、付勢部材８８ｂとを有する。軸部８８ａは、被支持部８７ａを貫通する。付勢部材８８ｂは軸部８８ａに支持される。係止部材８７は、ヒンジユニット８８を介して、ハウジング５０のロック取付部５９に取付けられる。ロック取付部５９は、一対の軸受部を有する。軸部８８ａの一端部が一対の軸受部の一方に支持され、軸部８８ａの他端部が一対の軸受部の他方に支持される。被支持部８７ａ及び付勢部材８８ｂは、ロック取付部５９の一対の軸受部の間に収容される。 The hinge unit 88 has a shaft portion 88a and a biasing member 88b. The shaft portion 88a passes through the supported portion 87a. The biasing member 88b is supported by the shaft portion 88a. The locking member 87 is attached to the lock attachment portion 59 of the housing 50 via the hinge unit 88 . The lock attachment portion 59 has a pair of bearing portions. One end portion of the shaft portion 88a is supported by one of the pair of bearing portions, and the other end portion of the shaft portion 88a is supported by the other of the pair of bearing portions. The supported portion 87 a and the biasing member 88 b are accommodated between the pair of bearing portions of the lock attachment portion 59 .
　係止部材８７は、軸部８８ａを介してハウジング５０に回動可能に取付けられる。なお、本例では、軸部８８ａは、ロック取付部５９に圧入されるなどして回動不能に支持され、係止部材８７と軸部８８ａとが回動可能とされる。係止部材８７と軸部８８ａとが圧入されるなどして回動不能に支持され、軸部８８ａがロック取付部５９に回動可能に支持されてもよい。 The locking member 87 is rotatably attached to the housing 50 via the shaft portion 88a. In this example, the shaft portion 88a is press-fitted into the lock mounting portion 59 and supported so as not to be rotatable, so that the locking member 87 and the shaft portion 88a are rotatable. The locking member 87 and the shaft portion 88 a may be press-fitted to be non-rotatably supported, and the shaft portion 88 a may be rotatably supported by the lock mounting portion 59 .
　付勢部材８８ｂは、係止部材側付勢部材の一例である。付勢部材８８ｂは、係止部材８７を回動方向に沿って第１位置に付勢する。付勢部材８８ｂは、ばねなどの弾性部材であってもよい。図１１に示す例では、付勢部材８８ｂとしてねじりコイルバネが用いられている。なお、係止部８７ｂ及び突出部８７ｃの少なくとも一方が、係止部材８７を第１位置からさらに回動することを規制してもよい。例えば、係止部８７ｂがリッド８２と接触することによって、係止部材８７が第１位置からさらに回動することが規制されてもよい。また例えば、突出部８７ｃが筒状枠部５２の外周面に接触することによって、係止部材８７が第１位置からさらに回動することが規制されてもよい。 The biasing member 88b is an example of a locking member-side biasing member. The biasing member 88b biases the locking member 87 to the first position along the rotation direction. The biasing member 88b may be an elastic member such as a spring. In the example shown in FIG. 11, a torsion coil spring is used as the biasing member 88b. At least one of the locking portion 87b and the projecting portion 87c may restrict further rotation of the locking member 87 from the first position. For example, further rotation of the locking member 87 from the first position may be restricted by contacting the locking portion 87b with the lid 82 . Further, for example, further rotation of the locking member 87 from the first position may be restricted by contact of the projecting portion 87c with the outer peripheral surface of the tubular frame portion 52 .
　＜開閉操作＞
　図１３をさらに参照しつつ、リッドユニット８０の開閉操作について説明する。図１３は係止部材８７が第１位置と第２位置との中間位置にある様子を示す図である。 <Open/close operation>
Further referring to FIG. 13, the opening and closing operation of the lid unit 80 will be described. FIG. 13 is a diagram showing a state where the locking member 87 is at an intermediate position between the first position and the second position.
　＜開操作＞
　まず閉状態にあるリッド８２の開操作について説明する。作業者は、図９に示すような閉状態にあるリッド８２の係止部材８７を操作してリッド８２を開くことができる。この際、図１３に示すように、作業者は、作業者の指ＷＦなどによって係止部材８７を操作して第１位置から第２位置に向けて回動させる。リッド８２と筒状枠部５２とが固着していない場合、係止部材８７が回動して係止部８７ｂが被係止部８２ｂから離れると、リッド８２は付勢部材８４ｂの付勢力によって開く。 <Open operation>
First, the opening operation of the lid 82 in the closed state will be described. The operator can open the lid 82 by operating the locking member 87 of the lid 82 in the closed state as shown in FIG. At this time, as shown in FIG. 13, the operator operates the locking member 87 with the operator's finger WF or the like to rotate it from the first position toward the second position. When the lid 82 and the cylindrical frame portion 52 are not fixed to each other, the lid 82 is moved by the biasing force of the biasing member 84b when the locking member 87 rotates and the locking portion 87b separates from the locked portion 82b. open.
　リッド８２が筒状枠部５２に固着していると、何ら対策されていない場合には、係止部材８７が回動して係止部８７ｂが被係止部８２ｂから離れてもリッド８２は付勢部材８４ｂの付勢力に抗して閉じたままとなり得る。 If the lid 82 is fixed to the cylindrical frame portion 52, the lid 82 will not move even if the locking member 87 rotates and the locking portion 87b separates from the locked portion 82b unless any measures are taken. It can remain closed against the biasing force of biasing member 84b.
　本開示では、突出部８７ｃが設けられることによって、リッド８２が筒状枠部５２に固着していても、リッド８２が開きやすい。すなわち、係止部材８７が回動して係止部８７ｂが被係止部８２ｂから離れたときに、図１３に示すように、突出部８７ｃが固着しているリッド８２を開く方向に押す。この力Ｆを受けて、リッド８２と筒状枠部５２との固着が解消され、リッド８２が開くことができる。本例では、リッド８２に付勢部材８４ｂによって開方向への付勢力が与えられる。従って、突出部８７ｃによるリッド８２の押し上げ動作によってリッド８２とハウジング５０との固着部分を剥がすきっかけが与えられると、リッド８２は付勢部材８４ｂによって閉状態から開状態に移行することができる。 In the present disclosure, even if the lid 82 is fixed to the cylindrical frame portion 52, the lid 82 can be easily opened by providing the protruding portion 87c. That is, when the locking member 87 rotates and the locking portion 87b separates from the locked portion 82b, the projecting portion 87c pushes the fixed lid 82 in the opening direction, as shown in FIG. By receiving this force F, the fixation between the lid 82 and the tubular frame portion 52 is released, and the lid 82 can be opened. In this example, the lid 82 is given a biasing force in the opening direction by a biasing member 84b. Therefore, when the projecting portion 87c pushes up the lid 82 to separate the fixed portion between the lid 82 and the housing 50, the lid 82 can be shifted from the closed state to the open state by the biasing member 84b.
　また本例では、スペーサ部８７ｈが設けられているため、係止部材８７とロック取付部５９との接触面積が小さくなる。このため、水が氷るなどして、係止部材８７とロック取付部５９とが固着していたとしても、作業者が、係止部材８７を操作するために必要な力の増加量が大きくなることが抑制される。これにより、作業者がリッド８２を開きやすくなる。 Also, in this example, since the spacer portion 87h is provided, the contact area between the locking member 87 and the lock mounting portion 59 is reduced. Therefore, even if the locking member 87 and the lock mounting portion 59 are fixed due to freezing of water or the like, the amount of increase in force required for the operator to operate the locking member 87 increases. is suppressed. This makes it easier for the operator to open the lid 82 .
　＜閉操作＞
　図１０に示すような開状態にあるリッド８２の閉操作について説明する。なお、図１０では、係止部材８７が第２位置にある。本例では、係止部材８７に付勢部材８８ｂによって第１位置への付勢力が与えられる。作業者の指ＷＦが係止部材８７から離れると、係止部材８７は、付勢部材８８ｂの付勢力によって回動する。作業者の指ＷＦが係止部材８７から離れた場合、リッド８２が開状態においても、係止部材８７は、第１位置に位置する。 <Close operation>
The closing operation of the lid 82 in the open state as shown in FIG. 10 will be described. In addition, in FIG. 10, the locking member 87 is in the second position. In this example, the locking member 87 is biased toward the first position by the biasing member 88b. When the operator's finger WF is separated from the locking member 87, the locking member 87 is rotated by the biasing force of the biasing member 88b. When the operator's finger WF is separated from the locking member 87, the locking member 87 is positioned at the first position even when the lid 82 is in the open state.
　開状態のリッド８２が閉じられる際、係止部材８７が第１位置にいると、係止部８７ｂが被係止部８２ｂの軌道上に位置する。このため、リッド８２が閉じられる途中で、係止部８７ｂが被係止部８２ｂと干渉する。この際、リッド８２及び係止部材８７が干渉したときの力を、係止部材８７を第２位置に回動させる力に変換する力変換部が設けられる。かかる力変換部として、被係止部８２ｂに上記ガイド部８２ｄが設けられると共に、係止部８７ｂに上記ガイド部８７ｅが設けられている。 When the lid 82 in the open state is closed, if the locking member 87 is in the first position, the locking portion 87b is positioned on the track of the locked portion 82b. Therefore, while the lid 82 is being closed, the locking portion 87b interferes with the locked portion 82b. At this time, a force converting portion is provided that converts the force when the lid 82 and the locking member 87 interfere with each other into a force for rotating the locking member 87 to the second position. As such force converting portions, the guide portion 82d is provided on the engaged portion 82b, and the guide portion 87e is provided on the engaging portion 87b.
　２つのガイド部８２ｄ、８７ｅが接触した状態で、さらにリッド８２が閉じられると、ガイド部８２ｄがガイド部８７ｅを押す。ガイド部８７ｅがガイド部８２ｄと接触する面が傾斜面となっているため、ガイド部８７ｅがガイド部８２ｄから受ける力が、係止部材８７を第２位置に向けて回動させる力に変換される。これにより、係止部材８７が第２位置に向けて回動し、被係止部８２ｂが係止部８７ｂを通過できる。 When the lid 82 is further closed while the two guide portions 82d and 87e are in contact with each other, the guide portion 82d pushes the guide portion 87e. Since the surface of the guide portion 87e that contacts the guide portion 82d is an inclined surface, the force that the guide portion 87e receives from the guide portion 82d is converted into a force that rotates the locking member 87 toward the second position. be. As a result, the locking member 87 rotates toward the second position, and the locked portion 82b can pass through the locking portion 87b.
　被係止部８２ｂが係止部８７ｂを通過すると、リッド８２が閉状態の位置となる。また、２つのガイド部８２ｄ、８７ｅの接触状態が解消され、係止部材８７が付勢部材８８ｂの付勢力によって回動し、第１位置に位置する。これにより、係止部８７ｂが被係止部８２ｂに係止した状態となる。 When the locked portion 82b passes through the locking portion 87b, the lid 82 is positioned in the closed state. Further, the contact state between the two guide portions 82d and 87e is released, and the locking member 87 is rotated by the biasing force of the biasing member 88b to be positioned at the first position. As a result, the locking portion 87b is locked to the locked portion 82b.
　＜効果等＞
　以上のように構成された充電コネクタ１０によると、係止部材８７が第１位置から第２位置に回動する際、突出部８７ｃがリッド８２を押し上げ可能な位置に設けられているため、凍結時などにリッド８２及びハウジング５０が固着している場合においても、リッド８２が開きやすくなる。また、突出部８７ｃがリッド８２を押し上げる動作が、係止部材８７が第１位置から第２位置に回動する動作に組込まれるため、作業者が行う動作が増えることが抑制される。 <Effects, etc.>
According to the charging connector 10 configured as described above, when the locking member 87 is rotated from the first position to the second position, the projecting portion 87c is provided at a position where the lid 82 can be pushed up. Even when the lid 82 and the housing 50 are stuck to each other, the lid 82 can be easily opened. In addition, since the operation of pushing up the lid 82 by the protruding portion 87c is included in the operation of rotating the locking member 87 from the first position to the second position, an increase in the number of operations performed by the operator is suppressed.
　また、係止部材８７は、係止部８７ｂの天面８７ｄに形成され、軸部８８ａの延在方向に沿って延びる一条の凸部８７ｆをさらに有する。これにより、作業者が係止部材８７を操作する際、凸部８７ｆが引掛かりとなって滑りにくくなり、係止部材８７の操作が容易となる。 In addition, the locking member 87 further has a single protrusion 87f formed on the top surface 87d of the locking portion 87b and extending along the extending direction of the shaft portion 88a. As a result, when the operator operates the locking member 87, the projection 87f becomes a hook and does not slip easily, and the locking member 87 can be easily operated.
　また、凸部８７ｆは、天面８７ｄのうちリッド８２から遠い側の端部に設けられている。これにより、作業者が係止部材８７を第１位置から第２位置に操作する際、凸部８７ｆが引掛かりとなりやすい。 In addition, the convex portion 87f is provided at the end of the top surface 87d farther from the lid 82 . As a result, when the operator operates the locking member 87 from the first position to the second position, the projection 87f is likely to be caught.
　また、リッド８２の内面８３ａには、シール部材８９の内側に沿って延びる環状の第１リブ８３ｄが形成されている。これにより、リッド８２にリッド８２とは別部材であるシール部材８９が設けられる際、第１リブ８３ｄが位置決めに使用されることができる。 An annular first rib 83d extending along the inner side of the seal member 89 is formed on the inner surface 83a of the lid 82 . Thereby, when the lid 82 is provided with the seal member 89 which is a separate member from the lid 82, the first rib 83d can be used for positioning.
　また、リッド８２の内面８３ａには、リッド８２の中央部から第１リブ８３ｄに向かって放射状に延びる複数の第２リブ８３ｅが形成されている。これにより、リッド８２の剛性が高められる。 Further, the inner surface 83a of the lid 82 is formed with a plurality of second ribs 83e radially extending from the central portion of the lid 82 toward the first ribs 83d. Thereby, the rigidity of the lid 82 is increased.
　また、リッド８２の内面８３ａには、第１リブ８３ｄの内側に環状の第３リブ８３ｆが形成されており、複数の第２リブ８３ｅは、第３リブ８３ｆを起点として第１リブ８３ｄに向けて延びている。これにより、中央部において複数の第２リブ８３ｅが交わることが抑制され、リッド８２の成形性が高まる。より詳細には、リッド８２が金型一体成形される際、複数の第２リブ８３ｅがリッド８２の中央部において一点に集中すると、集中部分が肉厚となり、ボイド、ヒケなどが生じやすくなる。これに対して、本例では、中央部において複数の第２リブ８３ｅが交わることが抑制されるため、局所的に肉厚となる部分が生じにくくなり、ボイド、ヒケなどが生じにくくなる。また、複数の第２リブ８３ｅがリッド８２の中央部において一点に集中すると、金型において第２リブ８３ｅ同士が交差する部分が鋭角となり、金型の耐久性が低くなる恐れがある。これに対して、本例では、複数の第２リブ８３ｅの一端部が離間しているため、鋭角が生じにくくなり、金型の耐久性の低下が抑制される。 An annular third rib 83f is formed inside the first rib 83d on the inner surface 83a of the lid 82, and the plurality of second ribs 83e extend from the third rib 83f toward the first rib 83d. extended. This prevents the plurality of second ribs 83e from crossing each other at the central portion, thereby enhancing the formability of the lid 82. As shown in FIG. More specifically, when the lid 82 is molded integrally with the mold, if the plurality of second ribs 83e are concentrated at one point in the central portion of the lid 82, the concentrated portion becomes thick, and voids and sink marks are likely to occur. On the other hand, in this example, since the plurality of second ribs 83e are prevented from intersecting at the central portion, localized thick portions are less likely to occur, and voids and sink marks are less likely to occur. Moreover, if the plurality of second ribs 83e are concentrated at one point in the central portion of the lid 82, the intersections of the second ribs 83e in the mold form an acute angle, which may reduce the durability of the mold. On the other hand, in this example, since the one ends of the plurality of second ribs 83e are spaced apart, acute angles are less likely to occur, and a decrease in durability of the mold is suppressed.
　また第１リブ８３ｄ、第２リブ８３ｅ及び第３リブ８３ｆのそれぞれが設けられることによって、リッド本体８３が薄い場合でも、リッド本体８３の反りなどの変形が抑制される。 Further, by providing the first rib 83d, the second rib 83e, and the third rib 83f, deformation such as warping of the lid body 83 is suppressed even when the lid body 83 is thin.
　また、スペーサ部８７ｈの周囲の位置において、被支持部８７ａの外面とロック取付部５９の軸受部の内面とが互いに離間しつつ対向している。これにより、係止部材８７とロック取付部５９との接触面積が小さくなり、係止部材８７とロック取付部５９とが凍結などにより固着していても、作業者による係止部材８７の操作の弊害となることが抑制される。 In addition, at positions around the spacer portion 87h, the outer surface of the supported portion 87a and the inner surface of the bearing portion of the lock mounting portion 59 face each other while being separated from each other. As a result, the contact area between the locking member 87 and the lock mounting portion 59 is reduced, and even if the locking member 87 and the lock mounting portion 59 are fixed due to freezing or the like, the operator cannot operate the locking member 87. Harmfulness is suppressed.
　また、被係止部８２ｂの外面８２ｃは、リッド本体８３の外面８３ｇより筒状枠部５２側に低くなっている。これにより、車外方向に向かう係止部８７ｂの突出寸法が小さくなる。 Further, the outer surface 82c of the locked portion 82b is lower than the outer surface 83g of the lid body 83 toward the tubular frame portion 52 side. As a result, the projecting dimension of the engaging portion 87b toward the outside of the vehicle is reduced.
　また、充電コネクタ１０は、係止部材８７を回動方向に沿って第１位置に向けて付勢する付勢部材８８ｂをさらに備える。これにより、突出部８７ｃがリッド８２を押し上げる動作が、作業者が付勢部材８８ｂの付勢力に抗して、係止部材８７を第１位置から第２位置に向けて回動させる動作に組込まれる。 The charging connector 10 further includes a biasing member 88b that biases the locking member 87 toward the first position along the rotation direction. As a result, the action of the projecting portion 87c pushing up the lid 82 is combined with the action of the worker rotating the locking member 87 from the first position toward the second position against the biasing force of the biasing member 88b. be
　また、充電コネクタ１０は、リッド８２を回動方向に沿って開状態に付勢する付勢部材８４ｂをさらに備える。これにより、突出部８７ｃによるリッド８２の押し上げ動作によってリッド８２とハウジング５０との固着部分を剥がすきっかけが与えられると、付勢部材８４ｂによってリッド８２が閉状態から開状態に移行することができる。 In addition, the charging connector 10 further includes a biasing member 84b that biases the lid 82 to the open state along the rotation direction. As a result, when the projecting portion 87c pushes the lid 82 upward and the lid 82 and the housing 50 are separated from each other, the lid 82 can be moved from the closed state to the open state by the urging member 84b.
　［付記］
　図１４は変形例にかかる充電コネクタ１１０を示す背面図である。なお、図１４において、信号線３４などの一部の部材が省略されている。また、本変形例の説明において、これまで説明したものと同様構成要素については同一符号を付してその説明を省略する。 [Appendix]
FIG. 14 is a rear view showing charging connector 110 according to a modification. 14, some members such as the signal line 34 are omitted. In addition, in the description of this modified example, the same reference numerals are given to the same components as those described so far, and the description thereof will be omitted.
　図１４に示す充電コネクタ１１０では、シグナル端子２４が８つ設けられている。また本例では、グランド端子２６が省略されている。これに伴い、ハウジング１５０及びリテーナ１６０において、グランド端子２６にかかる構造が省略されている。この充電コネクタ１１０においても、上記リッドユニット８０が採用されることができる。 In the charging connector 110 shown in FIG. 14, eight signal terminals 24 are provided. Also, in this example, the ground terminal 26 is omitted. Along with this, in the housing 150 and the retainer 160, the structure related to the ground terminal 26 is omitted. The lid unit 80 can be employed in this charging connector 110 as well.
　図１５は、ハウジング５０とリッドユニット８０との取付態様の変形例を示す斜視図である。図１６は図１５のＸＶＩ－ＸＶＩ線に沿った断面図である。図１７は図１６と同じ位置の断面図であり、リッド８２が閉じた状態を示す図である。 FIG. 15 is a perspective view showing a modification of the manner of mounting the housing 50 and the lid unit 80. FIG. 16 is a cross-sectional view taken along line XVI--XVI of FIG. 15. FIG. FIG. 17 is a cross-sectional view of the same position as FIG. 16, showing a state in which the lid 82 is closed.
　本変形例において、リッド側付勢部材としての付勢部材８４ｂは、ばね本体部８４ｃと、ばね本体部８４ｃから延びるばねアーム部８４ｄとを含む。リッド８２及びハウジング５０の少なくとも一方には、付勢部材８４ｂの取付姿勢が正規姿勢とは異なる姿勢の場合に、ばねアーム部８４ｄと干渉する干渉部８２ｆが設けられている。これにより、付勢部材８４ｂが正規姿勢とは異なる姿勢で取付けられることが抑制される。 In this modification, the biasing member 84b as the lid-side biasing member includes a spring main body portion 84c and a spring arm portion 84d extending from the spring main body portion 84c. At least one of the lid 82 and the housing 50 is provided with an interference portion 82f that interferes with the spring arm portion 84d when the mounting posture of the biasing member 84b is different from the normal posture. This prevents the biasing member 84b from being attached in a posture different from the normal posture.
　具体的には、ここでは付勢部材８４ｂはねじりコイルばねであり、ばね本体部８４ｃはコイルばねである。ここでは、付勢部材８４ｂはリッド８２を開状態に付勢している。従って、リッド８２が閉状態のときのばね本体部８４ｃの状態よりも、リッド８２が開状態のときのばね本体部８４ｃの状態の方が、自然状態に近い。 Specifically, here, the biasing member 84b is a torsion coil spring, and the spring body 84c is a coil spring. Here, the biasing member 84b biases the lid 82 to the open state. Therefore, the state of the spring body 84c when the lid 82 is open is closer to the natural state than the state of the spring body 84c when the lid 82 is closed.
　ばねアーム部８４ｄは、一対設けられる。一対のばねアーム部８４ｄは、ばね本体部８４ｃの一端および他端からそれぞれ延びる。各ばねアーム部８４ｄは、ばね本体部８４ｃの端部から延びる第１延出部分８４ｅと、第１延出部分８４ｅの先端から第１延出部分８４ｅと交差する方向に延びる第２延出部分８４ｆとを含む。ここでは第１延出部分８４ｅは、ばね本体部８４ｃの端部から当該端部におけるコイルばねの接線方向に延びる。ここでは第２延出部分８４ｆは、ばね本体部８４ｃの軸方向に延びる。 A pair of spring arm portions 84d are provided. A pair of spring arm portions 84d extend from one end and the other end of the spring body portion 84c, respectively. Each spring arm portion 84d has a first extension portion 84e extending from the end of the spring body portion 84c and a second extension portion extending from the tip of the first extension portion 84e in a direction crossing the first extension portion 84e. 84f. Here, the first extending portion 84e extends from the end of the spring body portion 84c in the tangential direction of the coil spring at that end. Here, the second extension portion 84f extends in the axial direction of the spring body portion 84c.
　一対のばねアーム部８４ｄのうち一方のばねアーム部８４ｄ１は、ハウジング５０のばね支持面５８ａに支持される。ばねアーム部８４ｄ１において、第２延出部分８４ｆがばね支持面５８ａに支持される。一対のばねアーム部８４ｄのうち他方のばねアーム部８４ｄ２は、リッド８２のばね支持面８２ｅに支持される。ばねアーム部８４ｄ２において、第２延出部分８４ｆがばね支持面８２ｅに支持される。 One spring arm portion 84d1 of the pair of spring arm portions 84d is supported by the spring support surface 58a of the housing 50. In the spring arm portion 84d1, the second extending portion 84f is supported by the spring support surface 58a. The other spring arm portion 84 d 2 of the pair of spring arm portions 84 d is supported by the spring support surface 82 e of the lid 82 . In the spring arm portion 84d2, the second extending portion 84f is supported by the spring support surface 82e.
　ここでは、一対のばねアーム部８４ｄが対称な形状に形成されており、付勢部材８４ｂは、ばね本体部８４ｃの軸方向に沿った一方側から見たときと他方側から見たときとで同じ形を有する。つまり、ばねアーム部８４ｄ１の第１延出部分８４ｅと、ばねアーム部８４ｄ２の第１延出部分８４ｅとは、互いに同じ長さを有する。また、ばねアーム部８４ｄ１の第２延出部分８４ｆと、ばねアーム部８４ｄ２の第２延出部分８４ｆとは、互いに同じ長さを有する。また、ばねアーム部８４ｄ１の第２延出部分８４ｆと、ばねアーム部８４ｄ２の第２延出部分８４ｆとは、互いに接近する向き又は互いに離れる向き（ここでは互いに接近する向き）に延びる。ばね本体部８４ｃに上記軸部８４ａが挿通される。軸部８４ａの一端に対して、付勢部材８４ｂの軸方向に沿った一端及び他端のいずれが位置してもよい。つまり、ばね本体部８４ｃに対する軸部８４ａの挿入向きは任意であり、一対のばねアーム部８４ｄのいずれが軸部８４ａの一端に位置しても、付勢部材８４ｂは正規姿勢をとることができる。 Here, the pair of spring arm portions 84d are formed in symmetrical shapes, and the biasing member 84b is different when viewed from one side and the other side along the axial direction of the spring body portion 84c. have the same shape. That is, the first extension portion 84e of the spring arm portion 84d1 and the first extension portion 84e of the spring arm portion 84d2 have the same length. Further, the second extending portion 84f of the spring arm portion 84d1 and the second extending portion 84f of the spring arm portion 84d2 have the same length. In addition, the second extending portion 84f of the spring arm portion 84d1 and the second extending portion 84f of the spring arm portion 84d2 extend toward each other or away from each other (here, toward each other). The shaft portion 84a is inserted through the spring body portion 84c. Either one end or the other end of the biasing member 84b along the axial direction may be positioned with respect to one end of the shaft portion 84a. In other words, the insertion direction of the shaft portion 84a with respect to the spring main body portion 84c is arbitrary, and the biasing member 84b can assume a normal posture regardless of which of the pair of spring arm portions 84d is positioned at one end of the shaft portion 84a. .
　ばねアーム部８４ｄは、リッド８２の開閉操作にかかる外力を受ける部分である。ばねアーム部８４ｄが受けた外力がばね本体部８４ｃに伝わり、ばね本体部８４ｃの弾性変形状態が変わる。ここでは、付勢部材８４ｂの正規姿勢は、図１６の矢符Ｆ１の向きに外力を受ける取付姿勢に設定されている。ねじりコイルバネである付勢部材８４ｂにおいて、リッド８２の開閉時に一対のばねアーム部８４ｄが操作される向きが、軸回りの一方の向きＦ１であるときが正規姿勢であり、他方の向きＦ２であるときが正規姿勢と異なる姿勢である。 The spring arm portion 84d is a portion that receives an external force applied to the opening and closing operation of the lid 82. The external force received by the spring arm portion 84d is transmitted to the spring main body portion 84c, and the elastic deformation state of the spring main body portion 84c changes. Here, the normal posture of the biasing member 84b is set to a mounting posture in which an external force is received in the direction of arrow F1 in FIG. In the biasing member 84b, which is a torsion coil spring, the direction in which the pair of spring arm portions 84d are operated when opening and closing the lid 82 is the normal posture when one direction F1 around the axis is the normal posture, and the other direction F2. When is a posture different from the normal posture.
　作業者が開状態のリッド８２を閉める操作は、リッド８２を押す操作である。当該操作にかかる力がリッド８２のばね支持面８２ｅから付勢部材８４ｂに対して矢符Ｆ１の向きに作用し、ばね本体部８４ｃが変形する。リッド８２が閉状態の位置に来たときに、ロックユニット８６の係止部材８７がロック位置に回動することによってリッド８２がロックされる。これにより、付勢部材８４ｂが弾性復帰しようとしてリッド８２を押しても、リッド８２が動くことが抑制され、リッド８２が閉状態において、ばね本体部８４ｃが変形状態に維持される。 The operator's operation of closing the open lid 82 is an operation of pushing the lid 82 . A force applied to the operation acts from the spring support surface 82e of the lid 82 to the biasing member 84b in the direction of the arrow F1, and the spring main body 84c is deformed. When the lid 82 reaches the closed position, the lid 82 is locked by rotating the locking member 87 of the lock unit 86 to the lock position. As a result, even if the urging member 84b pushes the lid 82 to elastically return, the lid 82 is prevented from moving, and the spring body 84c is maintained in the deformed state when the lid 82 is closed.
　作業者が閉状態のリッド８２を開ける操作は、ロックユニット８６を解除する操作である。当該操作にかかる力は、付勢部材８４ｂに及ばない。ロックユニット８６の係止部材８７が退避位置に回動してリッド８２のロックが解除されることによって、リッド８２が付勢部材８４ｂの弾性復帰にかかる力を支えきれなくなる。これにより、付勢部材８４ｂが弾性復帰すると共に、リッド８２が開く。 The operator's operation of opening the closed lid 82 is an operation of releasing the lock unit 86 . The force applied to the operation does not reach the biasing member 84b. When the locking member 87 of the lock unit 86 rotates to the retracted position and the lid 82 is unlocked, the lid 82 cannot support the elastic return force of the biasing member 84b. As a result, the biasing member 84b is elastically restored and the lid 82 is opened.
　ここでは、干渉部８２ｆは、付勢部材８４ｂの取付姿勢が、図１６の矢符Ｆ２の向きに外力を受ける姿勢となることを抑制する。付勢部材８４ｂの取付姿勢が、図１６の矢符Ｆ２の向きに外力を受ける姿勢となる場合について、図１５から図１７に加えて、図１８を参照しつつ説明する。図１８は付勢部材８４ｂの取付姿勢が逆向きとなる場合を示す図である。 Here, the interference portion 82f prevents the mounting posture of the biasing member 84b from receiving an external force in the direction of arrow F2 in FIG. A case in which the biasing member 84b is mounted in a posture that receives an external force in the direction of arrow F2 in FIG. 16 will be described with reference to FIGS. 15 to 17 and also to FIG. FIG. 18 is a diagram showing a case where the mounting posture of the biasing member 84b is reversed.
　付勢部材８４ｂの取付姿勢が、図１６の矢符Ｆ２の向きに外力を受ける姿勢となる場合、付勢部材８４ｂは、正規姿勢から軸部の周りに１８０度回転したような姿勢となる。当該取付姿勢において一対のばねアーム部８４ｄが支持される相手が、正規姿勢において一対のばねアーム部８４ｄが支持される相手とは逆となる。すなわち、一対のばねアーム部８４ｄ１、８４ｄ２のうち軸部８４ａの一端側に位置するばねアーム部８４ｄ１がリッド８２に支持され、軸部８４ａの他端側に位置するばねアーム部８４ｄ２がハウジング５０に支持される。 When the mounting posture of the biasing member 84b is such that it receives an external force in the direction of arrow F2 in FIG. The partner on which the pair of spring arm portions 84d are supported in the mounting posture is opposite to the partner on which the pair of spring arm portions 84d are supported in the normal posture. That is, of the pair of spring arm portions 84d1 and 84d2, the spring arm portion 84d1 located on one end side of the shaft portion 84a is supported by the lid 82, and the spring arm portion 84d2 located on the other end side of the shaft portion 84a is attached to the housing 50. Supported.
　ここでは干渉部８２ｆは、リッド８２に設けられている。干渉部８２ｆは、一対のばねアーム部８４ｄ１、８４ｄ２のうち軸部８４ａの一端側に位置するばねアーム部８４ｄ１の第１延出部分８４ｅと接触する位置に設けられている。干渉部８２ｆは、リッド８２のばね支持面８２ｅと連続する面のうちばね支持面８２ｅよりも軸部８４ａ側からハウジング５０のばね支持面５８ａに向けて突出するリブである。図１８の線Ｌは、ばね支持面８２ｅを通る軸部８４ａの接線Ｌである。例えば、干渉部８２ｆは、当該接線Ｌを越えて突出する。 Here, the interference portion 82f is provided on the lid 82. The interference portion 82f is provided at a position in contact with the first extending portion 84e of the spring arm portion 84d1 located on one end side of the shaft portion 84a of the pair of spring arm portions 84d1 and 84d2. The interference portion 82f is a rib that protrudes toward the spring support surface 58a of the housing 50 from the shaft portion 84a side of the spring support surface 82e of the surface continuous with the spring support surface 82e of the lid 82 . A line L in FIG. 18 is a tangent line L of the shaft portion 84a passing through the spring support surface 82e. For example, the interference portion 82f protrudes beyond the tangent line L.
　干渉部８２ｆは、軸部８４ａの軸方向に沿って、一端側に部分的に設けられている。軸部８４ａの軸方向に沿った他端側には干渉部８２ｆは設けられていない。これにより、干渉部８２ｆは、付勢部材８４ｂの取付姿勢が正規姿勢の場合に、軸部８４ａの他端側に位置するばねアーム部８４ｄ２の第１延出部分８４ｅと接触しない。また、干渉部８２ｆの突出量は、図１７に示すように付勢部材８４ｂが正規姿勢で取付けられ、かつリッド８２が閉状態にあるとき、軸部８４ａの一端側のばねアーム部８４ｄ１と接触しないように設定されてもよい。被支持部８２ａは、軸部８４ａが貫通する貫通部８２ｇを有する。貫通部８２ｇと支持面８２ｅを含む側部との交差部分に干渉部８２ｆが設けられている。 The interference portion 82f is partially provided on one end side along the axial direction of the shaft portion 84a. The interference portion 82f is not provided on the other end side along the axial direction of the shaft portion 84a. Accordingly, the interference portion 82f does not contact the first extending portion 84e of the spring arm portion 84d2 located on the other end side of the shaft portion 84a when the biasing member 84b is mounted in the normal posture. 17, when the biasing member 84b is attached in the normal posture and the lid 82 is in the closed state, the interference portion 82f contacts the spring arm portion 84d1 at one end of the shaft portion 84a. It may be set not to. The supported portion 82a has a through portion 82g through which the shaft portion 84a passes. An interfering portion 82f is provided at the intersection of the through portion 82g and the side portion including the support surface 82e.
　図１８の仮想線に示すように、付勢部材８４ｂが正規姿勢とは逆向きに取付けられそうになると、ばねアーム部８４ｄ１が干渉部８２ｆと接触する。これにより、作業者が付勢部材８４ｂの取付姿勢の誤りに気付きやすくなり、付勢部材８４ｂが正規姿勢とは異なる姿勢で取付けられることが抑制される。 As shown by the phantom line in FIG. 18, when the biasing member 84b is about to be attached in a direction opposite to the normal posture, the spring arm portion 84d1 comes into contact with the interference portion 82f. This makes it easier for the operator to notice an error in the mounting posture of the biasing member 84b, and prevents the biasing member 84b from being mounted in a posture different from the normal posture.
　さらに、図１８に示すリッドの開き角度は、付勢部材８４ｂが正規姿勢のときにリッドが最大限開いたときの開き角度と同じである。また図１８の仮想線で示される付勢部材８４ｂは、矢符Ｆ２の向きの力を受けた状態である。付勢部材８４ｂが、仮に図１８の仮想線に示す状態に取付けられた場合、ばねアーム部８４ｄ１が干渉部８２ｆの先端縁部と接触しているため、付勢部材８４ｂが弾性復帰しようとする力を干渉部８２ｆが支えきれずに、付勢部材８４ｂがリッド８２を押す。これにより、ばねアーム部８４ｄがリッドの支持面と接触するまでリッドが閉じる向きに回転し、リッドの開き角度は、図１８に示す角度（正規姿勢の開き角度）よりも小さくなる。これにより、作業者が付勢部材８４ｂの取付姿勢の誤りに気付きやすくなり、付勢部材８４ｂが正規姿勢とは異なる姿勢で取付けられることが抑制される。 Furthermore, the opening angle of the lid shown in FIG. 18 is the same as the opening angle when the lid is opened to the maximum when the biasing member 84b is in the normal posture. Also, the biasing member 84b indicated by the phantom line in FIG. 18 is in a state of receiving force in the direction of arrow F2. If the biasing member 84b is attached in the state indicated by the phantom lines in FIG. 18, the spring arm portion 84d1 is in contact with the tip edge of the interference portion 82f, so that the biasing member 84b tries to elastically return. The biasing member 84b pushes the lid 82 because the interference portion 82f cannot support the force. As a result, the lid rotates in the closing direction until the spring arm portion 84d comes into contact with the support surface of the lid, and the opening angle of the lid becomes smaller than the angle shown in FIG. 18 (the opening angle in the normal posture). This makes it easier for the operator to notice an error in the mounting posture of the biasing member 84b, and prevents the biasing member 84b from being mounted in a posture different from the normal posture.
　さらにここでは、干渉部８２ｆがリッド８２に突起状に設けられているため、リッド取付部５８の周辺において、水等が凍って氷が生じた場合でも、リッド８２の開閉操作時に突起状の干渉部８２ｆが当該氷を砕くことができる。これにより、凍結時にもリッドユニット８０が開きやすくなる。 Furthermore, here, since the interference portion 82f is provided in the lid 82 in a protruding manner, even if water or the like freezes to form ice in the vicinity of the lid mounting portion 58, the protruding interference occurs when the lid 82 is opened and closed. The portion 82f can crush the ice. This makes it easy to open the lid unit 80 even when frozen.
　このほかこれまで、係止部材８７は、係止部８７ｂの天面８７ｄに凸部８７ｆを有するものとして説明されたが、このことは必須の構成ではない。例えば、凸部８７ｆは設けられていなくてもよい。また凸部８７ｆが設けられる場合でも、その構成は上記したものに限られない。例えば、凸部８７ｆが天面８７ｄの中間部であってガイド部８７ｅの隣に設けられていてもよい。また例えば、凸部８７ｆは、一条ではなく複数設けられてもよい。この場合、天面８７ｄの高さが複数の凸部によって筒状枠部５２から離れる向きに段階的に高くなってもよい。 In addition, until now, the locking member 87 has been described as having a convex portion 87f on the top surface 87d of the locking portion 87b, but this is not an essential configuration. For example, the protrusion 87f may not be provided. Further, even when the convex portion 87f is provided, its configuration is not limited to the above. For example, the convex portion 87f may be provided in the intermediate portion of the top surface 87d and next to the guide portion 87e. Further, for example, a plurality of protrusions 87f may be provided instead of one. In this case, the height of the top surface 87d may be increased stepwise in the direction away from the cylindrical frame portion 52 by a plurality of convex portions.
　またこれまで、リッド８２の内面８３ａに、第１リブ８３ｄ、第２リブ８３ｅ及び第３リブ８３ｆが形成されているものとして説明されたが、このことは必須の構成ではない。第１リブ８３ｄ、第２リブ８３ｅ及び第３リブ８３ｆのいずれか又は全部が省略されてもよい。 Also, the description has been made so far that the first rib 83d, the second rib 83e and the third rib 83f are formed on the inner surface 83a of the lid 82, but this is not an essential configuration. Any or all of the first rib 83d, the second rib 83e and the third rib 83f may be omitted.
