Abstract

A vehicle-side connector (10) is provided with a vehicle-side housing (11), a plurality of vehicle-side power supply terminals (40) that are mounted to the vehicle-side housing (11), and a vehicle-side power supply terminal accommodation section (21) that is provided to the vehicle-side housing (11) and that separates adjacent vehicle-side power supply terminals (40) from each other. One portion of the vehicle-side power supply terminal accommodation section (21) is provided separately from the vehicle-side housing (11) and serves as a shielding tube (30) that is movable with respect to the vehicle-side housing along the fitting direction with a power source-side connector (60). The shielding tube (30) is biased toward the front side of the fitting direction by a compression coil spring (34). The shielding tube (30) retracts toward the back side of the fitting direction when fitted to the power source-side connector (60) and advances toward the front side of the fitting direction with the power source-side connector (60) as a result of biasing force from the compression coil spring (34) that accompanies a withdrawal movement from the power source-side connector (60).

Description

充電用コネクタCharging connector
　本発明は、充電用コネクタに関する。 The present invention relates to a charging connector.
　電気自動車等に搭載された蓄電装置を充電するための充電用コネクタは、車体に備えられて、車両に搭載された蓄電装置に接続される車両側コネクタと、充電用の電力を供給する給電設備に備えられた電源側コネクタとを嵌合接続するものである。

特開２００３－２４９３１７号公報JP 2003-249317 A
　このような事態を防止するため、種々の安全対策が提案されており、例えば隣り合う端子金具の間に永久磁石を配置し、永久磁石による磁界を利用してアークの発生を抑制したコネクタが提案されている（特許文献１参照）。
　しかし、上記のようなコネクタでは、永久磁石によってコネクタに鉄屑等が引き寄せられ、電源側端子と車両側端子との接続に悪影響を与えるおそれがあり、さらなる改善が求められていた。 In order to prevent such a situation, various safety measures have been proposed. For example, a connector in which a permanent magnet is arranged between adjacent terminal fittings and an arc is suppressed by using a magnetic field by the permanent magnet is proposed. (See Patent Document 1).
However, in the connector as described above, iron scraps or the like are attracted to the connector by the permanent magnet, which may adversely affect the connection between the power supply side terminal and the vehicle side terminal, and further improvement has been demanded.
　本発明は上記のような事情に基づいて完成されたものであって、アーク放電を抑制可能な充電用コネクタを提供することを目的とする。 The present invention has been completed based on the above situation, and an object thereof is to provide a charging connector capable of suppressing arc discharge.
　本発明は、車両に搭載された蓄電装置への充電を行うために用いられる充電用コネクタであって、相手側コネクタと嵌合可能なハウジングと、前記ハウジングに装着されて前記相手側コネクタに備えられた相手側端子と接続可能な複数の端子と、前記ハウジングに設けられて、隣り合う前記端子の間を仕切る隔壁とを備え、前記隔壁の少なくとも一部が、前記ハウジングとは別体に設けられて、前記ハウジングに対して前記相手側コネクタとの嵌合方向に沿って移動可能な可動部とされ、前記可動部と前記ハウジングとの間には前記可動部を前記相手側コネクタとの嵌合方向前方へ付勢する付勢部材が備えられ、前記可動部が、前記相手側コネクタと嵌合した状態では前記相手側コネクタに押圧されて前記相手側コネクタとの嵌合方向後方に後退し、前記相手側コネクタからの離脱動作に伴って前記付勢部材の付勢力によって前記相手側コネクタとの嵌合方向前方に前進するものである。 The present invention relates to a charging connector used for charging a power storage device mounted on a vehicle, a housing that can be fitted to a counterpart connector, and a connector that is attached to the housing and provided in the counterpart connector. A plurality of terminals connectable to the mating terminal, and a partition provided in the housing and partitioning between the adjacent terminals, wherein at least a part of the partition is provided separately from the housing The movable portion is movable along the fitting direction of the mating connector with respect to the housing, and the movable portion is fitted between the movable portion and the housing. An urging member for urging forward in the mating direction is provided, and the movable portion is pressed by the mating connector in a state of being mated with the mating connector, and the mating connector is behind the mating connector. Retracted by the urging force of the urging member in association with the withdrawal operation from the mating connector is to advance in the fitting direction forwardly of said mating connector.
　上記の構成によれば、相手側コネクタからの離脱動作に伴って可動部が前進し、隣り合う端子の間に介在する状態となる。この状態では、隣り合う端子同士の先端部の空間距離が、突出した可動部を回り込まなければならない分長くなる。このため、誤って充電中にコネクタが離脱させられるなどした場合においても、アーク放電を抑制することができる。 According to the above configuration, the movable portion moves forward in accordance with the detachment operation from the mating connector, and is interposed between adjacent terminals. In this state, the spatial distance between the tips of adjacent terminals becomes longer due to having to go around the protruding movable part. For this reason, even when the connector is accidentally detached during charging, arc discharge can be suppressed.
　上記構成の実施態様として以下の構成を備えれば好ましい。 It is preferable if the following configuration is provided as an embodiment of the above configuration.
　前記可動部が、前記端子の周囲を全周にわたって囲うものであってもよい。
　このような構成によれば、アークが可動部の側方から回り込んで隣接する端子に達することを防止できる。これにより、アーク放電をより効果的に抑制することができる。 The movable part may surround the periphery of the terminal over the entire circumference.
According to such a structure, it can prevent that an arc wraps around from the side of a movable part and reaches an adjacent terminal. Thereby, arc discharge can be suppressed more effectively.
　前記可動部および前記ハウジングにおいて互いに対向する面のうちいずれか一方に隣り合う前記端子の間を仕切る補助壁が設けられたものであってもよい。
　上記の構成によれば、可動部の前進に伴って、可動部の後端で隣り合う端子間に隙間が生じることを回避できる。これにより、隣り合う端子同士が短絡することを防止できる。 The movable part and the housing may be provided with an auxiliary wall for partitioning between the adjacent terminals on either one of surfaces facing each other.
According to said structure, it can avoid that a clearance gap produces between the terminals which adjoin at the rear end of a movable part with advance of a movable part. Thereby, it can prevent that adjacent terminals short-circuit.
　前記充電用コネクタが急速充電用コネクタであってもよい。
　ここで、短時間での充電が可能な急速充電を行う場合には、両コネクタ間を流れる電流値が大きなものとなるため、アーク放電による不具合を抑制したいとの要望が強い。このため、急速充電用コネクタにおいて本発明の構成を好適に適用できる。 The charging connector may be a quick charging connector.
Here, in the case of performing quick charging that can be charged in a short time, since the value of current flowing between both connectors becomes large, there is a strong demand for suppressing defects due to arc discharge. For this reason, the structure of this invention can be applied suitably in the connector for quick charge.
　前記端子が雄型端子であってもよい。
　雄型端子は、雌型端子と比べ、先端が尖っているため、アーク放電が発生しやすい。このため、雄型端子を備える充電用コネクタに本発明の構成を好適に適用できる。 The terminal may be a male terminal.
Since the male terminal is sharper than the female terminal, arc discharge is likely to occur. For this reason, the structure of this invention can be applied suitably to the connector for charging provided with a male terminal.
　本発明によれば、アーク放電を抑制可能な充電用コネクタを提供することができる。 According to the present invention, a charging connector capable of suppressing arc discharge can be provided.

（電源側コネクタ６０の車両側コネクタ１０からの離脱動作）
　次に、以上のように構成された電源側コネクタ６０が、車両側コネクタ１０から離脱する際の動作について説明する。 (Removal operation of power supply side connector 60 from vehicle side connector 10)
Next, the operation when the power supply side connector 60 configured as described above is detached from the vehicle side connector 10 will be described.
　電源側コネクタ６０と車両側コネクタ１０とが嵌合した状態では、車両側コネクタ１０の嵌合筒部１２の内部に電源側コネクタ６０のコネクタ部６４が収容され、電源側給電用端子収容孔６６および電源側信号用端子収容孔６８の内部に車両側給電用端子収容部２１および車両側信号用端子収容部２５が収容されている。そして、車両側給電用端子４０と電源側給電用端子７０、車両側信号用端子５０と電源側信号用端子７５がそれぞれ電気的に接続されている。 In a state in which the power supply side connector 60 and the vehicle side connector 10 are fitted, the connector portion 64 of the power supply side connector 60 is accommodated in the fitting cylinder portion 12 of the vehicle side connector 10, and the power supply side power supply terminal accommodating hole 66 is accommodated. The vehicle-side power supply terminal accommodating portion 21 and the vehicle-side signal terminal accommodating portion 25 are accommodated in the power-side signal terminal accommodating hole 68. The vehicle-side power supply terminal 40 and the power-supply-side power supply terminal 70 are electrically connected to each other, and the vehicle-side signal terminal 50 and the power-supply-side signal terminal 75 are electrically connected.
　このとき、遮蔽筒３０は、電源側給電用端子収容孔６６の区画壁６７に押圧されて、圧縮コイルばね３４を圧縮しつつ、その前壁３２が車両側給電用端子収容部２１の先端面に当接する位置（退避位置）まで押し込まれている。 At this time, the shielding cylinder 30 is pressed against the partition wall 67 of the power supply side power supply terminal accommodating hole 66 to compress the compression coil spring 34, and the front wall 32 is the front end surface of the vehicle side power supply terminal accommodating portion 21. It is pushed in to the position (retracted position) where it contacts.
　電源側コネクタ６０の離脱が開始されると、電源側コネクタ６０の引き抜き動作に伴い、コネクタ部６４が車両側コネクタ１０の嵌合筒部１２がに対して後退していく。このとき、電源側給電用端子収容孔６６の区画壁６７も、車両側給電用端子収容部２１に対して相対的に後退していく。そして、圧縮コイルばね３４の付勢力により、遮蔽筒３０が前進していく。 When the separation of the power supply side connector 60 is started, the connector portion 64 moves backward with respect to the fitting cylinder portion 12 of the vehicle side connector 10 with the pulling operation of the power supply side connector 60. At this time, the partition wall 67 of the power supply side power supply terminal accommodating hole 66 is also retracted relative to the vehicle side power supply terminal accommodating portion 21. Then, the shielding cylinder 30 moves forward by the urging force of the compression coil spring 34.
　電源側コネクタ６０の離脱が進むと、電源側給電用端子７０と車両側給電用端子４０との接続が解除される。ここで、誤って充電中に電源側コネクタ６０が車両側コネクタ１０から引き抜かれるなどした場合には、隣り合う車両側給電用端子４０間にアーク放電が発生することがある。 When the power supply side connector 60 is removed, the connection between the power supply side power supply terminal 70 and the vehicle side power supply terminal 40 is released. Here, when the power supply side connector 60 is accidentally pulled out from the vehicle side connector 10 during charging, arc discharge may occur between the adjacent vehicle side power supply terminals 40.
　しかし、このとき、遮蔽筒３０が車両側給電用端子収容部２１の先端面に当接する位置（退避位置）よりも前方位置（遮蔽位置）にある。この状態では遮蔽筒３０の前端位置が、車両側給電用端子４０の先端位置よりも前方（電源側コネクタ６０との嵌合面側）にあり、車両側給電用端子４０の先端部の周囲が遮蔽筒３０によって囲われ、隣り合う車両側給電用端子４０の間に遮蔽筒３０が介在する状態となる。この状態では、隣り合う車両側給電用端子４０同士の先端部の空間距離が、突出した遮蔽筒３０を回り込まなければならない分長くなる。このため、アーク放電を抑制することができる。 However, at this time, the shielding cylinder 30 is in a position (shielding position) in front of the position (retracted position) where it comes into contact with the front end surface of the vehicle-side power feeding terminal accommodating portion 21. In this state, the front end position of the shielding cylinder 30 is in front of the front end position of the vehicle side power supply terminal 40 (on the side of the fitting surface with the power supply side connector 60), and the periphery of the front end portion of the vehicle side power supply terminal 40 is The shielding cylinder 30 is interposed between the adjacent vehicle-side power supply terminals 40 surrounded by the shielding cylinder 30. In this state, the spatial distance between the tip portions of the adjacent vehicle-side power feeding terminals 40 becomes longer due to having to go around the protruding shielding cylinder 30. For this reason, arc discharge can be suppressed.
　さらに離脱が進むと、コネクタ部６４の先端が車両側フード部１４の先端から充分に離れた状態となり、電源側コネクタ６０の車両側コネクタ１０からの離脱が完了する。 When the detachment further proceeds, the tip of the connector part 64 is sufficiently separated from the tip of the vehicle side hood part 14, and the detachment of the power supply side connector 60 from the vehicle side connector 10 is completed.
（まとめ）
　以上のように本実施形態によれば、車両側コネクタ１０は、相手側である電源側コネクタ６０と嵌合可能な車両側ハウジング１１と、この車両側ハウジング１１に装着されて電源側コネクタに備えられた電源側給電用端子７０と接続可能な複数の車両側給電用端子４０と、車両側ハウジング１１に設けられて、隣り合う車両側給電用端子４０の間を仕切る車両側給電用端子収容部２１とを備えている。そして、車両側給電用端子収容部２１の一部が、車両側ハウジング１１とは別体に設けられて、車両側ハウジング１１に対して電源側コネクタ６０との嵌合方向に沿って移動可能な遮蔽筒３０とされている。この遮蔽筒３０と収容部本体２２との間には圧縮コイルばね３４が備えられ、この圧縮コイルばね３４によって、遮蔽筒３０が電源側コネクタ６０との嵌合方向前方へ付勢されている。遮蔽筒３０は、車両側コネクタ１０が電源側コネクタ６０と嵌合した状態では電源側コネクタ６０に押圧されて電源側コネクタ６０との嵌合方向後方に後退し、電源側コネクタ６０からの離脱動作に伴って圧縮コイルばね３４の付勢力によって電源側コネクタ６０との嵌合方向前方に前進するようにされている。 (Summary)
As described above, according to the present embodiment, the vehicle-side connector 10 includes the vehicle-side housing 11 that can be fitted to the power-side connector 60 that is the counterpart, and the power-side connector that is attached to the vehicle-side housing 11. A plurality of vehicle-side power supply terminals 40 connectable to the power-supply-side power supply terminals 70, and a vehicle-side power supply terminal accommodating portion that is provided in the vehicle-side housing 11 and partitions between adjacent vehicle-side power supply terminals 40. 21. A part of the vehicle-side power supply terminal accommodating portion 21 is provided separately from the vehicle-side housing 11 and is movable along the fitting direction of the power-side connector 60 with respect to the vehicle-side housing 11. The shielding cylinder 30 is used. A compression coil spring 34 is provided between the shielding cylinder 30 and the accommodating portion main body 22, and the shielding cylinder 30 is urged forward in the fitting direction with the power supply side connector 60 by the compression coil spring 34. When the vehicle-side connector 10 is fitted to the power-side connector 60, the shielding cylinder 30 is pressed by the power-side connector 60 and retracts backward in the fitting direction with the power-side connector 60, and is detached from the power-side connector 60. Along with this, the biasing force of the compression coil spring 34 moves forward in the fitting direction with the power supply side connector 60.
　上記の構成によれば、電源側コネクタ６０からの離脱動作に伴って遮蔽筒３０が前進し、隣り合う車両側給電用端子４０の間に介在する状態となる。この状態では、隣り合う車両側給電用端子４０同士の先端部の空間距離が、突出した遮蔽筒３０を回り込まなければならない分長くなる。このため、誤って充電中に車両側コネクタ１０から電源側コネクタ６０が離脱させられるなどした場合においても、アーク放電を抑制することができる。 According to the above configuration, the shielding cylinder 30 moves forward with the detachment operation from the power supply side connector 60, and is interposed between the adjacent vehicle side power supply terminals 40. In this state, the spatial distance between the tip portions of the adjacent vehicle-side power feeding terminals 40 becomes longer due to having to go around the protruding shielding cylinder 30. For this reason, even when the power supply side connector 60 is detached from the vehicle side connector 10 during charging, arc discharge can be suppressed.
　また、遮蔽筒３０が、車両側給電用端子４０の周囲を全周にわたって囲うものである。このような構成によれば、アークが遮蔽筒３０の側方から回り込んで隣接する車両側給電用端子４０に達することを防止できる。これにより、アーク放電をより効果的に抑制することができる。 Moreover, the shielding cylinder 30 surrounds the periphery of the vehicle-side power supply terminal 40 over the entire circumference. According to such a configuration, it is possible to prevent the arc from wrapping around from the side of the shielding cylinder 30 and reaching the adjacent vehicle-side power feeding terminal 40. Thereby, arc discharge can be suppressed more effectively.
　さらに、本実施形態の車両側コネクタ１０および電源側コネクタ６０は、急速充電用のコネクタである。ここで、短時間での充電が可能な急速充電を行う場合には、両コネクタ１０、６０間を流れる電流値が大きなものとなる。このため、遮蔽筒３０を設けてアーク放電による不具合を抑制することが好ましい。 Furthermore, the vehicle side connector 10 and the power supply side connector 60 of this embodiment are connectors for quick charging. Here, in the case of performing quick charging that can be charged in a short time, the value of the current flowing between both connectors 10 and 60 becomes large. For this reason, it is preferable to provide the shielding cylinder 30 to suppress problems due to arc discharge.

Further, the inner diameter of the compression coil spring 140 is designed to be substantially equal to the inner diameters of the first reduced diameter portion 132 and the second reduced diameter portion 122. Further, the length of the compression coil spring 140 is slightly longer than the length obtained by adding the length of the second enlarged diameter portion 134 and the length of the third enlarged diameter portion 121 in an uncompressed state. Thus, in a state where no force is applied to the compression coil spring 140, the shielding wall 130 is biased forward by the compression coil spring 140, and its front end protrudes forward from the power supply side hood portion 113. Yes.
　タワー側ピン挿通孔１３１および本体側ピン挿通孔１２０には、ピン１４１が挿入されている。このピン１４１は、細長い円柱状に形成されたピン本体１４２と、このピン本体１４２の前端に形成され、ピン本体１４２よりも大きな外径を有する頭部１４３とを備えている。ピン本体１４２の外径は、圧縮コイルばね１４０、第１縮径部１３２および第２縮径部１２２の内径にほぼ等しく設計され、頭部１４３の外径は第１拡径部１３３の内径にほぼ等しく設計されている。このピン１４１は、前方からタワー側ピン挿通孔１３１に挿入され、その後端が本体側ピン挿通孔１２０の奥壁に突き当たるまで押し込まれている。このとき、ばね収容部１２４に収容された圧縮コイルばね１４０の内部にピン本体１４２が挿通された状態となる。 A pin 141 is inserted into the tower side pin insertion hole 131 and the main body side pin insertion hole 120.

The outer diameter of the pin main body 142 is designed to be approximately equal to the inner diameters of the compression coil spring 140, the first reduced diameter portion 132, and the second reduced diameter portion 122, and the outer diameter of the head 143 is the same as the inner diameter of the first enlarged diameter portion 133. Designed almost equally. The pin 141 is inserted from the front into the tower side pin insertion hole 131 and is pushed in until the rear end of the pin 141 hits the back wall of the main body side pin insertion hole 120. At this time, the pin main body 142 is inserted into the compression coil spring 140 accommodated in the spring accommodating portion 124.
　ピン本体１４２の長さは、第１縮径部１３２、第２拡径部１３４および本体側ピン挿通孔１２０の長さを足した長さよりもやや長くされており、頭部１４３と第１段差部１３５との間に、圧縮コイルばね１４０の付勢力によって遮蔽壁１３０が前方に移動できるだけのゆとりを持たせるようにされている。そして、圧縮コイルばね１４０の付勢力によって遮蔽壁１３０が前方に押し出される際に、ピン１４１の頭部１４３が第１段差部１３５に突き当たることによって、遮蔽壁１３０の前方への抜け止めが図られている。 The length of the pin main body 142 is slightly longer than the length obtained by adding the lengths of the first reduced diameter portion 132, the second enlarged diameter portion 134, and the main body side pin insertion hole 120. Between the portion 135, the shielding wall 130 has a clearance enough to move forward by the urging force of the compression coil spring 140. Then, when the shielding wall 130 is pushed forward by the urging force of the compression coil spring 140, the head 143 of the pin 141 abuts against the first step portion 135, thereby preventing the shielding wall 130 from coming off forward. ing.

The vehicle-side tower portion 164 is formed by paralleling two vehicle-side terminal accommodating portions 165 formed in a cylindrical shape. Each vehicle-side terminal accommodating portion 165 is designed such that its outer diameter is slightly smaller than the inner diameter of the power-side terminal accommodating portion 115 and can be inserted into the power-side terminal accommodating portion 115. The front end position of each vehicle side terminal accommodating portion 165 is slightly behind the front end position of the power supply side hood portion 113.
　車両側ハウジング本体１６２において２つの車両側端子収容部１６５と整合する位置には、前後方向に貫通する貫通孔１６６が設けられている。貫通孔１６６の内部空間は、車両側端子収容部１６５の内部空間と連通しており、貫通孔１６６の内径は、車両側端子収容部１６５の内径よりやや大きくされている。この貫通孔１６６と車両側端子収容部１６５の内部空間とが車両側端子収容孔１６７を形成する。この車両側端子収容孔１６７には、車両側給電用端子１６８（相手側端子に該当）が収容されている。 A through hole 166 that penetrates in the front-rear direction is provided at a position in the vehicle-side housing main body 162 that is aligned with the two vehicle-side terminal accommodating portions 165. The internal space of the through hole 166 communicates with the internal space of the vehicle side terminal housing portion 165, and the internal diameter of the through hole 166 is slightly larger than the internal diameter of the vehicle side terminal housing portion 165. The through hole 166 and the internal space of the vehicle side terminal accommodating portion 165 form a vehicle side terminal accommodating hole 167. The vehicle-side terminal accommodation hole 167 accommodates a vehicle-side power supply terminal 168 (corresponding to a counterpart terminal).
　車両側給電用端子１６８は、円柱状をなす本体部１６９と、本体部１６９から前方に突出した複数の接触片１７０と、本体部１６９から後方に突出するバレル部１７１とを備えている。複数の接触片１７０は、本体部１６９の前端部に形成されて前方に開口する筒状部において、その前端開口縁から後方に向けて切り欠くことによって形成されるスリットを周方向に間欠的に複数本設けることによって形成されている。この種の端子は、すり割り端子などの名称で呼ばれる場合がある。また、バレル部１７１には、電線（図示せず）の一端部において露出された芯線が圧着されている。電線の他端部は、車両側ハウジング１６１の後端から延出され、図示しない蓄電装置に接続される。本体部１６９の後端位置には、外方に鍔状に張り出すフランジ部１７２が形成されている。 The vehicle-side power feeding terminal 168 includes a cylindrical main body 169, a plurality of contact pieces 170 protruding forward from the main body 169, and a barrel 171 protruding rearward from the main body 169.

Although not shown in detail, a retainer is disposed behind the barrel portion 171 to prevent the vehicle-side power feeding terminal 168 from coming off backward.
（電源側コネクタ１１０の車両側コネクタ１６０からの離脱動作）
　次に、以上のように構成された電源側コネクタ１１０が、車両側コネクタ１６０から離脱する際の動作について説明する。 (Removal operation of power supply side connector 110 from vehicle side connector 160)
Next, the operation when the power supply side connector 110 configured as described above is detached from the vehicle side connector 160 will be described.
　電源側コネクタ１１０と車両側コネクタ１６０とが嵌合した状態では、電源側フード部１１３の内部に車両側フード部１６３が収容され、電源側端子収容部１１５の内部に車両側端子収容部１６５が収容されている。そして、車両側給電用端子１６８と電源側給電用端子１５０とが電気的に接続されている。 In a state where the power supply side connector 110 and the vehicle side connector 160 are fitted, the vehicle side hood portion 163 is accommodated inside the power supply side hood portion 113, and the vehicle side terminal accommodation portion 165 is located inside the power supply side terminal accommodation portion 115. Contained. The vehicle-side power supply terminal 168 and the power supply-side power supply terminal 150 are electrically connected.
　このとき、電源側タワー部１１４の連結部１１６が、２つの車両側端子収容部１６５の隙間に進入し、その先端が車両側フード部１６３の奥壁（車両側ハウジング本体１６２の前端面１６２Ａ）に突き当てられている。これにより、遮蔽壁１３０は、車両側ハウジング本体１６２の前端面１６２Ａに押圧されて、圧縮コイルばね１４０を圧縮しつつ、その後端が電源側フード部１１３の奥壁（電源側ハウジング本体１１２の前端面１１２Ａ）に当接する位置（退避位置）まで押し込まれている。 At this time, the connecting portion 116 of the power supply side tower portion 114 enters the gap between the two vehicle side terminal accommodating portions 165, and the tip thereof is the rear wall of the vehicle side hood portion 163 (the front end surface 162A of the vehicle side housing main body 162). Has been hit. As a result, the shielding wall 130 is pressed against the front end face 162A of the vehicle-side housing main body 162 and compresses the compression coil spring 140, while its rear end is the back wall of the power-side hood 113 (the front end of the power-side housing main body 112). It is pushed in to the position (retracted position) that contacts the surface 112A).
　電源側コネクタ１１０の離脱が開始されると、電源側コネクタ１１０の引き抜き動作に伴い、車両側コネクタ１６０が電源側コネクタ１１０に対して相対的に後退していく。このとき、車両側ハウジング本体１６２の前端面１６２Ａも、遮蔽壁１３０に対して相対的に後退していく。すると、圧縮コイルばね１４０の付勢力により、遮蔽壁１３０が前進していく。 When the disconnection of the power supply side connector 110 is started, the vehicle side connector 160 moves backward relative to the power supply side connector 110 with the pulling operation of the power supply side connector 110. At this time, the front end surface 162 </ b> A of the vehicle-side housing body 162 is also retracted relative to the shielding wall 130. Then, the shielding wall 130 moves forward by the urging force of the compression coil spring 140.
　電源側コネクタ１１０の離脱が進むと、電源側給電用端子１５０と車両側給電用端子１６８との接続が解除される。ここで、誤って充電中に電源側コネクタ１１０が車両側コネクタ１６０から引き抜かれるなどした場合には、隣り合う電源側給電用端子１５０間にアーク放電が発生することがある。 When the disconnection of the power supply side connector 110 proceeds, the connection between the power supply side power supply terminal 150 and the vehicle side power supply terminal 168 is released. Here, when the power supply side connector 110 is accidentally pulled out from the vehicle side connector 160 during charging, an arc discharge may occur between the adjacent power supply side power supply terminals 150.
　しかし、このとき、遮蔽壁１３０が電源側ハウジング本体１１２の前端面１１２Ａに当接する位置（退避位置）よりも前方位置（遮蔽位置）にある。この状態では遮蔽壁１３０の前端位置が、電源側給電用端子１５０の先端位置よりも前方（電源側コネクタ１１０との嵌合面側）にあり、隣り合う電源側給電用端子１５０の間に遮蔽壁１３０が介在する状態となる。この状態では、隣り合う電源側給電用端子１５０同士の先端部の空間距離が、突出した遮蔽壁１３０を回り込まなければならない分長くなる。このため、アーク放電を抑制することができる。 However, at this time, the shielding wall 130 is at a position (shielding position) in front of the position (retracted position) where the shielding wall 130 contacts the front end surface 112A of the power supply side housing body 112. In this state, the front end position of the shielding wall 130 is in front of the front end position of the power supply side power supply terminal 150 (on the side of the fitting surface with the power supply side connector 110) and is shielded between the adjacent power supply side power supply terminals 150. The wall 130 is interposed. In this state, the spatial distance between the tips of the adjacent power supply side power supply terminals 150 becomes longer due to having to go around the protruding shielding wall 130. For this reason, arc discharge can be suppressed.
　さらに離脱が進むと、電源側フード部１１３の先端が車両側フード部１６３の先端から充分に離れた状態となり、電源側コネクタ１１０の車両側コネクタ１６０からの離脱が完了する。 When the detachment further proceeds, the tip of the power supply side hood portion 113 is sufficiently separated from the tip of the vehicle side hood portion 163, and the release of the power supply side connector 110 from the vehicle side connector 160 is completed.
（まとめ）
　以上のように本実施形態によれば、電源側コネクタ１１０は、相手側である車両側コネクタ１６０と嵌合可能な電源側ハウジング１１１と、この電源側ハウジング１１１に装着されて車両側コネクタ１６０に備えられた車両側給電用端子１６８と接続可能な複数の電源側給電用端子１５０と、電源側ハウジング１１１に設けられて、隣り合う電源側給電用端子１５０の間を仕切る電源側タワー部１１４とを備えている。そして、電源側タワー部１１４の一部が、電源側ハウジング１１１とは別体に設けられて、電源側ハウジング１１１に対して電源側コネクタ１１０との嵌合方向に沿って移動可能な遮蔽壁１３０とされている。この遮蔽壁１３０と電源側ハウジング１１１との間には圧縮コイルばね１４０が備えられ、この圧縮コイルばね１４０によって、遮蔽壁１３０が車両側コネクタ１６０との嵌合方向前方へ付勢されている。遮蔽壁１３０は、電源側コネクタ１１０が車両側コネクタ１６０と嵌合した状態では車両側コネクタ１６０に押圧されて車両側コネクタ１６０との嵌合方向後方に後退し、車両側コネクタ１６０からの離脱動作に伴って圧縮コイルばね１４０の付勢力によって車両側コネクタ１６０との嵌合方向前方に前進するようにされている。 (Summary)

A part of the power supply side tower portion 114 is provided separately from the power supply side housing 111, and the shielding wall 130 is movable along the fitting direction of the power supply side connector 110 with respect to the power supply side housing 111. It is said that. A compression coil spring 140 is provided between the shielding wall 130 and the power supply side housing 111, and the shielding wall 130 is urged forward in the fitting direction with the vehicle side connector 160 by the compression coil spring 140. In a state where the power supply side connector 110 is fitted to the vehicle side connector 160, the shielding wall 130 is pressed by the vehicle side connector 160 and moves backward in the fitting direction with the vehicle side connector 160, so that the shielding wall 130 is detached from the vehicle side connector 160. Along with this, the urging force of the compression coil spring 140 moves forward in the fitting direction with the vehicle-side connector 160.
　上記の構成によれば、車両側コネクタ１６０からの離脱動作に伴って遮蔽壁１３０が前進し、隣り合う電源側給電用端子１５０の間に介在する状態となる。この状態では、隣り合う電源側給電用端子１５０同士の先端部の空間距離が、突出した遮蔽壁１３０を回り込まなければならない分長くなる。このため、誤って充電中に車両側コネクタ１６０から電源側コネクタ１１０が離脱させられるなどした場合においても、アーク放電を抑制することができる。 According to the above configuration, the shielding wall 130 moves forward with the detachment operation from the vehicle-side connector 160 and is interposed between the adjacent power-supply-side power supply terminals 150. In this state, the spatial distance between the tips of the adjacent power supply side power supply terminals 150 becomes longer due to having to go around the protruding shielding wall 130. For this reason, even when the power supply side connector 110 is detached from the vehicle side connector 160 during charging by mistake, arc discharge can be suppressed.
　また、短時間での充電が可能な急速充電を行う場合には、両コネクタ１１０、１６０間を流れる電流値が大きなものとなるため、アーク放電による不具合を抑制したいとの要望が強い。このため、急速充電用のコネクタにおいて上記の構成を好適に適用できる。 In addition, when performing quick charging that can be charged in a short time, the value of the current flowing between both connectors 110 and 160 becomes large, so there is a strong demand for suppressing defects due to arc discharge. For this reason, said structure can be applied suitably in the connector for quick charge.
　さらに、電源側コネクタ１１０に備えられる車両側給電用端子１５０は、雄型の端子である。ここで、雄型端子は、雌型端子と比べ、先端が尖っているため、アーク放電が発生しやすい。このため、雄型端子を備えるコネクタに上記の構成を好適に適用できる。 Furthermore, the vehicle-side power supply terminal 150 provided in the power supply-side connector 110 is a male terminal. Here, since the tip of the male terminal is sharper than the female terminal, arc discharge is likely to occur. For this reason, said structure is suitably applicable to a connector provided with a male terminal.
　＜実施形態３＞
　次に、本発明の実施形態３を、図１９～図２７を参照しつつ詳細に説明する。本実施形態の車両側コネクタ１６０および電源側コネクタ２１０は、「Combined Charging System（ＣＣＳ方式）」に適合した、電気自動車等の急速充電用のコネクタである。本実施形態では、電源側コネクタ２１０が充電用コネクタ、車両側コネクタ１６０が相手側コネクタに該当する。なお、ＣＣＳ方式のコネクタは、一般に、普通充電用のコネクタと急速充電用のコネクタとが一体化されたものであるが、以下の説明においては、急速充電用のコネクタについてのみ説明する。また、以下の説明においては、電源側コネクタ２１０および車両側コネクタ１６０において、相手側コネクタとの嵌合面側を前側とする。 <Embodiment 3>
Next, Embodiment 3 of the present invention will be described in detail with reference to FIGS. The vehicle-side connector 160 and the power supply-side connector 210 of this embodiment are connectors for rapid charging of an electric vehicle or the like that are compatible with the “Combined Charging System (CCS method)”. In the present embodiment, the power supply side connector 210 corresponds to a charging connector, and the vehicle side connector 160 corresponds to a mating connector. In general, a CCS connector is a connector in which a normal charging connector and a quick charging connector are integrated. In the following description, only the quick charging connector will be described. In the following description, in the power supply side connector 210 and the vehicle side connector 160, the fitting surface side with the mating connector is the front side.
（電源側コネクタ２１０）
　電源側コネクタ２１０は、充電用の電力を供給するための給電装置に備えられるものであって、合成樹脂製によって形成された電源側ハウジング２１１（ハウジングに該当）を備える。この電源側ハウジング２１１は、横長ブロック状の電源側ハウジング本体２１２と、この電源側ハウジング本体２１２の前端面から前方に突出する筒状の電源側フード部２１３とを備える。 (Power supply side connector 210)
The power supply side connector 210 is provided in a power supply device for supplying power for charging, and includes a power supply side housing 211 (corresponding to a housing) formed of a synthetic resin. The power supply side housing 211 includes a horizontally long block-shaped power supply side housing main body 212 and a cylindrical power supply side hood portion 213 protruding forward from the front end face of the power supply side housing main body 212.
　電源側フード部２１３内には、電源側ハウジング本体２１２とは別体に形成された電源側タワー部２１４（隔壁、可動部に該当）が配されている。この電源側タワー部２１４は、円筒状に形成された２つの電源側端子収容部２１５が並列し、その間を連結部２１６で連結した形状をなしている。この電源側タワー部２１４は、電源側端子収容部２１５における円筒の軸方向が、相手側である車両側コネクタ１６０との嵌合方向に沿う向きで電源側フード部２１３内に配されている。各電源側端子収容部２１５の前端位置は、電源側フード部２１３の前端位置とほぼ同位置とされている。 In the power supply side hood part 213, a power supply side tower part 214 (corresponding to a partition wall and a movable part) formed separately from the power supply side housing body 212 is disposed. The power supply side tower portion 214 has a shape in which two power supply side terminal accommodating portions 215 formed in a cylindrical shape are arranged in parallel and connected by a connecting portion 216. The power supply side tower portion 214 is arranged in the power supply side hood portion 213 such that the axial direction of the cylinder in the power supply side terminal accommodating portion 215 is along the fitting direction with the vehicle side connector 160 which is the counterpart side. The front end position of each power supply side terminal accommodating portion 215 is substantially the same position as the front end position of the power supply side hood portion 213.
　電源側ハウジング本体２１２において２つの電源側端子収容部２１５と整合する位置には、実施形態２と同様に貫通孔１６６が設けられている。この貫通孔１６６と電源側端子収容部２１５の内部空間とが電源側端子収容孔２１８を形成する。この電源側端子収容孔２１８には、電源側給電用端子１５０が収容されている。電源側給電用端子１５０の構成は、実施形態２と同様であるので、同一の符号を付して説明を省略する。 In the power supply side housing body 212, a through hole 166 is provided at a position where it is aligned with the two power supply side terminal accommodating portions 215, as in the second embodiment. The through hole 166 and the internal space of the power supply side terminal accommodating portion 215 form a power supply side terminal accommodating hole 218. The power supply side power supply terminal 150 is accommodated in the power supply side terminal accommodation hole 218. Since the configuration of the power supply side power supply terminal 150 is the same as that of the second embodiment, the same reference numerals are given and description thereof is omitted.
　電源側タワー部２１４の連結部２１６には、２箇所に、前後方向に貫通するタワー側ピン挿通孔１３１が形成されている。一方、電源側ハウジング本体２１２の前端面においてタワー側ピン挿通孔１３１に整合する位置には、前方に開口する有底の本体側ピン挿通孔１２０が形成されている。そして、このタワー側ピン挿通孔１３１および本体側ピン挿通孔１２０には、ピン１４１および圧縮コイルばね１４０が収容されている。これらのタワー側ピン挿通孔１３１、本体側ピン挿通孔１２０、ピン１４１、および圧縮コイルばね１４０の構成は、実施形態２と同様であるので、同一の符号を付して説明を省略する。圧縮コイルばね１４０に力が加えられていない状態では、電源側タワー部２１４が圧縮コイルばね１４０により前方へ付勢され、その前端が電源側フード部２１３よりも前方に突出するようにされている。この際、ピン１４１の頭部１４３が第１段差部１３５に突き当たることによって、電源側タワー部２１４の前方への抜け止めが図られている。 The tower-side pin insertion holes 131 that penetrate in the front-rear direction are formed at two locations in the connecting portion 216 of the power-side tower portion 214. On the other hand, a bottomed body-side pin insertion hole 120 that opens forward is formed at a position that aligns with the tower-side pin insertion hole 131 on the front end surface of the power supply-side housing body 212. And the pin 141 and the compression coil spring 140 are accommodated in the tower side pin insertion hole 131 and the main body side pin insertion hole 120. Since the configurations of the tower side pin insertion hole 131, the main body side pin insertion hole 120, the pin 141, and the compression coil spring 140 are the same as those of the second embodiment, the same reference numerals are given and the description thereof is omitted. In a state where no force is applied to the compression coil spring 140, the power supply side tower portion 214 is biased forward by the compression coil spring 140, and its front end protrudes forward from the power supply side hood portion 213. . At this time, the head portion 143 of the pin 141 abuts against the first stepped portion 135, thereby preventing the power supply side tower portion 214 from coming off forward.
（車両側コネクタ１６０）
　この電源側コネクタ２１０と嵌合される車両側コネクタ１６０の構成は、実施形態２と同様であるので、同一の符号を付して説明を省略する。 (Vehicle side connector 160)
Since the configuration of the vehicle-side connector 160 fitted to the power-side connector 210 is the same as that of the second embodiment, the same reference numerals are given and the description thereof is omitted.
（電源側コネクタ２１０の車両側コネクタ１６０からの離脱動作）
　次に、以上のように構成された電源側コネクタ２１０が、車両側コネクタ１６０から離脱する際の動作について説明する。 (Removal operation of power supply side connector 210 from vehicle side connector 160)
Next, the operation when the power supply side connector 210 configured as described above is detached from the vehicle side connector 160 will be described.
　電源側コネクタ２１０と車両側コネクタ１６０とが嵌合した状態では、電源側フード部２１３の内部に車両側フード部１６３が収容され、電源側端子収容部２１５の内部に車両側端子収容部１６５が収容されている。そして、車両側給電用端子１６８と電源側給電用端子１５０とが電気的に接続されている。 In a state where the power supply side connector 210 and the vehicle side connector 160 are fitted, the vehicle side hood portion 163 is accommodated inside the power supply side hood portion 213, and the vehicle side terminal accommodation portion 165 is located inside the power supply side terminal accommodation portion 215. Contained. The vehicle-side power supply terminal 168 and the power supply-side power supply terminal 150 are electrically connected.
　このとき、電源側タワー部２１４が、電源側フード部２１３と２つの車両側端子収容部１６５の隙間に進入し、その先端が車両側フード部１６３の奥壁（車両側ハウジング本体１６２の前端面１６２Ａ）に突き当てられている。これにより、電源側タワー部２１４は、車両側ハウジング本体１６２の前端面１６２Ａに押圧されて、圧縮コイルばね１４０を圧縮しつつ、その後端が電源側フード部２１３の奥壁（電源側ハウジング本体２１２の前端面２１２Ａ）に当接する位置（退避位置）まで押し込まれている。 At this time, the power supply side tower portion 214 enters the gap between the power supply side hood portion 213 and the two vehicle side terminal accommodating portions 165, and the tip thereof is the rear wall of the vehicle side hood portion 163 (the front end surface of the vehicle side housing body 162). 162A). As a result, the power-side tower 214 is pressed against the front end face 162A of the vehicle-side housing body 162 and compresses the compression coil spring 140, while its rear end is the back wall of the power-side hood 213 (the power-side housing body 212). Is pushed to the position (retracted position) that contacts the front end surface 212A).
　電源側コネクタ２１０の離脱が開始されると、電源側コネクタ２１０の引き抜き動作に伴い、車両側コネクタ１６０が電源側コネクタ２１０に対して相対的に後退していく。このとき、車両側ハウジング本体１６２の前端面１６２Ａも、電源側タワー部２１４に対して相対的に後退していく。すると、圧縮コイルばね１４０の付勢力により、電源側タワー部２１４が前進していく。 When the disconnection of the power supply side connector 210 is started, the vehicle side connector 160 moves backward relative to the power supply side connector 210 along with the pulling out operation of the power supply side connector 210. At this time, the front end surface 162 </ b> A of the vehicle-side housing main body 162 also moves backward relative to the power-side tower portion 214. Then, the power supply side tower portion 214 moves forward by the urging force of the compression coil spring 140.
　電源側コネクタ２１０の離脱が進むと、電源側給電用端子１５０と車両側給電用端子１６８との接続が解除される。ここで、誤って充電中に電源側コネクタ２１０が車両側コネクタ１６０から引き抜かれるなどした場合には、隣り合う電源側給電用端子１５０間にアーク放電が発生することがある。 When the power connector 210 is removed, the connection between the power supply terminal 150 and the vehicle power supply terminal 168 is released. Here, when the power supply side connector 210 is accidentally pulled out of the vehicle side connector 160 during charging, an arc discharge may occur between the adjacent power supply side power supply terminals 150.
　しかし、このとき、電源側タワー部２１４が電源側ハウジング本体２１２の前端面２１２Ａに当接する位置（退避位置）よりも前方位置（遮蔽位置）にある。この状態では電源側タワー部２１４の前端位置が、電源側給電用端子１５０の先端位置よりも前方（電源側コネクタ２１０との嵌合面側）にあり、隣り合う電源側給電用端子１５０の間に介在する状態となる。この状態では、隣り合う電源側給電用端子１５０同士の先端部の空間距離が、突出した電源側タワー部２１４を回り込まなければならない分長くなる。このため、アーク放電を抑制することができる。 However, at this time, the power supply side tower portion 214 is at a front position (shielding position) from a position (retracted position) where the power supply side tower portion 214 contacts the front end surface 212A of the power supply side housing body 212. In this state, the front end position of the power supply side tower portion 214 is in front of the front end position of the power supply side power supply terminal 150 (the fitting surface side with the power supply side connector 210), and between the adjacent power supply side power supply terminals 150. It will be in the state intervening. In this state, the spatial distance between the front end portions of the adjacent power supply side power supply terminals 150 becomes longer due to having to go around the protruding power supply side tower portion 214. For this reason, arc discharge can be suppressed.
　さらに離脱が進むと、電源側フード部２１３の先端が車両側フード部１６３の先端から充分に離れた状態となり、電源側コネクタ２１０の車両側コネクタ１６０からの離脱が完了する。 When the detachment further proceeds, the tip of the power supply side hood portion 213 is sufficiently separated from the tip of the vehicle side hood portion 163, and the release of the power supply side connector 210 from the vehicle side connector 160 is completed.
（まとめ）
　以上のように本実施形態によれば、実施形態２と同様の作用効果が奏される。加えて、電源側タワー部２１４が、電源側給電用端子１５０の周囲を全周にわたって囲うものであり、この電源側タワー部２１４全体が圧縮コイルばね１５０によって前方へ付勢される。このような構成によれば、アークが電源側タワー部２１４の側方から回り込んで隣接する電源側給電用端子１５０に達することを防止できる。これにより、アーク放電をより効果的に抑制することができる。 (Summary)
As described above, according to the present embodiment, the same effects as those of the second embodiment can be obtained. In addition, the power supply side tower portion 214 surrounds the periphery of the power supply side power supply terminal 150 over the entire circumference, and the entire power supply side tower portion 214 is urged forward by the compression coil spring 150. According to such a configuration, the arc can be prevented from wrapping around from the side of the power supply side tower section 214 and reaching the adjacent power supply side power supply terminal 150. Thereby, arc discharge can be suppressed more effectively.
　＜実施形態４＞
　次に、本発明の実施形態３を、図２８～図３８を参照しつつ詳細に説明する。本実施形態の車両側コネクタ１６０および電源側コネクタ３１０は、「Combined Charging System（ＣＣＳ方式）」に適合した、電気自動車等の急速充電用のコネクタである。本実施形態では、電源側コネクタ３１０が充電用コネクタ、車両側コネクタ１６０が相手側コネクタに該当する。なお、ＣＣＳ方式のコネクタは、一般に、普通充電用のコネクタと急速充電用のコネクタとが一体化されたものであるが、以下の説明においては、急速充電用のコネクタについてのみ説明する。また、以下の説明においては、電源側コネクタ３１０および車両側コネクタ１６０において、相手側コネクタとの嵌合面側を前側とする。 <Embodiment 4>
Next, Embodiment 3 of the present invention will be described in detail with reference to FIGS. The vehicle-side connector 160 and the power supply-side connector 310 of this embodiment are connectors for rapid charging of an electric vehicle or the like that are compatible with the “Combined Charging System (CCS method)”. In the present embodiment, the power supply side connector 310 corresponds to the charging connector, and the vehicle side connector 160 corresponds to the counterpart connector. In general, a CCS connector is a connector in which a normal charging connector and a quick charging connector are integrated. In the following description, only the quick charging connector will be described. In the following description, in the power supply side connector 310 and the vehicle side connector 160, the fitting surface side with the mating connector is the front side.
（電源側コネクタ３１０）
　電源側コネクタ３１０は、充電用の電力を供給するための給電装置に備えられるものであって、合成樹脂製によって形成された電源側ハウジング３１１（ハウジングに該当）を備える。この電源側ハウジング３１１は、横長ブロック状の電源側ハウジング本体３１２と、この電源側ハウジング本体３１２の前端面３１２Ａから前方に突出する筒状の電源側フード部３１３とを備える。 (Power supply side connector 310)
The power supply side connector 310 is provided in a power supply device for supplying charging power, and includes a power supply side housing 311 (corresponding to a housing) formed of synthetic resin. The power supply side housing 311 includes a horizontally long block-shaped power supply side housing main body 312 and a cylindrical power supply side hood portion 313 protruding forward from a front end surface 312A of the power supply side housing main body 312.
　電源側フード部３１３内には、電源側ハウジング本体３１２の前端面から前方に突出する電源側タワー部３１４（隔壁に該当）が設けられている。この電源側タワー部３１４は、円筒状に形成された２つの電源側端子収容部３１５が並列し、その間を連結部３１６で連結した形状をなしている。各電源側端子収容部３１５の前端位置は、電源側フード部３１３の前端位置とほぼ同位置とされている。 In the power supply side hood portion 313, a power supply side tower portion 314 (corresponding to a partition wall) that protrudes forward from the front end surface of the power supply side housing body 312 is provided. The power supply side tower portion 314 has a shape in which two power supply side terminal accommodating portions 315 formed in a cylindrical shape are arranged in parallel and connected therebetween by a connecting portion 316. The front end position of each power supply side terminal accommodating portion 315 is substantially the same position as the front end position of the power supply side hood portion 313.
　電源側タワー部３１４は、電源側ハウジング本体３１２と一体形成されたタワー部本体３１７と、電源側ハウジング本体３１２とは別体に形成された遮蔽壁３３０（可動部に該当）とに分割されている。遮蔽壁３３０は、電源側タワー部３１４において、隣り合う電源側給電用端子１５０の間に配される部分、すなわち、連結部３１６と、電源側端子収容部３１５においてこの連結部３１６に接合している部分により構成されている。 The power supply side tower part 314 is divided into a tower part main body 317 formed integrally with the power supply side housing main body 312 and a shielding wall 330 (corresponding to a movable part) formed separately from the power supply side housing main body 312. Yes. The shielding wall 330 is joined to the connection portion 316 in the power supply side tower portion 314, that is, a portion disposed between the adjacent power supply side power supply terminals 150, that is, the connection portion 316 and the power supply side terminal accommodating portion 315. It is comprised by the part which is.
　電源側ハウジング本体３１２において２つの電源側端子収容部３１５と整合する位置には、前後方向に貫通する貫通孔３１８が設けられている。貫通孔３１８の内部空間は、電源側端子収容部３１５の内部空間と連通しており、貫通孔３１８の内径は、電源側端子収容部３１５の内径よりやや大きくされている。この貫通孔３１８と電源側端子収容部３１５の内部空間とが電源側端子収容孔３１９を形成する。この電源側端子収容孔３１９には、電源側給電用端子１５０が収容されている。電源側給電用端子１５０の構成は、実施形態２と同様であるので、同一の符号を付して説明を省略する。 A through-hole 318 that penetrates in the front-rear direction is provided at a position that matches the two power-side terminal accommodating portions 315 in the power-side housing body 312. The internal space of the through hole 318 communicates with the internal space of the power supply side terminal accommodating portion 315, and the internal diameter of the through hole 318 is slightly larger than the internal diameter of the power supply side terminal accommodating portion 315. The through hole 318 and the internal space of the power supply side terminal accommodating portion 315 form a power supply side terminal accommodating hole 319. The power supply side terminal accommodation hole 319 accommodates a power supply side power supply terminal 150. Since the configuration of the power supply side power supply terminal 150 is the same as that of the second embodiment, the same reference numerals are given and description thereof is omitted.
　電源側ハウジング本体３１２の前端面３１２Ａには、補助壁３２０が立設されている。この補助壁３２０は、電源側タワー部３１４の遮蔽壁３３０に整合する位置であって、隣り合う電源側給電用端子１５０を隔てる位置に形成されている。この補助壁３２０は、２つの電源側端子収容部３１５の並列方向とは直交する方向に細長い縦板部３２１と、この縦板部３２１の両端に設けられ、縦板部３２１の延び方向とは直交する方向に細長い横板部３２２とで構成され、断面Ｈ字形をなしている。 An auxiliary wall 320 is erected on the front end surface 312A of the power supply side housing body 312. The auxiliary wall 320 is formed at a position that is aligned with the shielding wall 330 of the power supply side tower section 314 and that separates the adjacent power supply side power supply terminals 150. The auxiliary wall 320 is provided in a direction that is elongated in the direction orthogonal to the parallel direction of the two power supply side terminal accommodating portions 315, and is provided at both ends of the vertical plate portion 321. It is composed of a transverse plate portion 322 that is elongated in the orthogonal direction, and has an H-shaped cross section.
　一方、遮蔽壁３３０の後端面において、この補助壁３２０に整合する位置には、補助壁収容孔３３１が設けられている。 On the other hand, an auxiliary wall accommodation hole 331 is provided on the rear end face of the shielding wall 330 at a position aligned with the auxiliary wall 320.
　補助壁収容孔３３１は、断面が補助壁収容孔３３１の断面と同形状のＨ字形をなしており、内部に補助壁３２０を挿入可能とされている。この補助壁収容孔３３１の深さは、補助壁３２０の突出高さよりもやや小さくされている。これにより、遮蔽壁３３０が電源側ハウジング本体３１２の前端面に突き当たるまで押し込まれた状態で、補助壁収容孔３３１の奥端面３３１Ａと補助壁３２０の突出端面３２３との間には若干の隙間が設けられる状態とされている。この隙間はばね収容部１２４とされ、ここには、板バネ３３４（付勢部材に該当）が収容されている。 The auxiliary wall accommodation hole 331 has an H-shaped cross section that is the same as the cross section of the auxiliary wall accommodation hole 331, and the auxiliary wall 320 can be inserted therein. The depth of the auxiliary wall accommodation hole 331 is slightly smaller than the protruding height of the auxiliary wall 320. Thus, a slight gap is formed between the rear end surface 331A of the auxiliary wall housing hole 331 and the protruding end surface 323 of the auxiliary wall 320 in a state where the shielding wall 330 is pushed in until it hits the front end surface of the power supply side housing body 312. It is supposed to be provided. This gap is used as a spring accommodating portion 124, in which a leaf spring 334 (corresponding to an urging member) is accommodated.
　板バネ３３４は、金属製の細長い板材をＶ字形に折り曲げることにより形成されたものであって、Ｖ字の一辺が補助壁収容孔３３１の奥端面３３１Ａに当接している。一方、Ｖ字の他辺はその先端部がＶ字の一辺に平行となるように折り曲げられて、補助壁３２０の突出端面３２３に当接している。板バネ３３４に力が加えられていない状態では、遮蔽壁３３０が板バネ３３４により前方へ付勢され、その前端が電源側フード部３１３よりも前方に突出するようにされている。 The plate spring 334 is formed by bending a metal elongated plate material into a V shape, and one side of the V shape is in contact with the back end surface 331A of the auxiliary wall accommodation hole 331. On the other hand, the other side of the V-shape is bent so that the front end portion is parallel to one side of the V-shape, and is in contact with the protruding end surface 323 of the auxiliary wall 320. In a state where no force is applied to the leaf spring 334, the shielding wall 330 is biased forward by the leaf spring 334, and its front end protrudes forward from the power supply side hood portion 313.
　補助壁における一対の横板部３２２の外側面（縦板部３２１が接続している側とは逆側の面）には、それぞれ係止片３２４が突設されている。一方、遮蔽壁３３０においてこの係止片３２４に整合する位置には、この係止片３２４を受け入れ可能な係止孔３３３が設けられている。係止孔３３３は、前後方向（電源側コネクタの車両側コネクタ１６０との嵌合方向に沿う方向）に細長く形成され、遮蔽壁３３０が補助壁３２０に対して前後方向に移動することを許容している。そして、板バネ３３４に力が加えられていない状態、すなわち遮蔽壁３３０が板バネ３３４により付勢されて前方へ移動した状態では、係止片３２４が係止孔３３３の孔縁に突き当てられることにより、遮蔽壁３３０の前方への抜け止めが図られる。 Locking pieces 324 project from the outer surfaces of the pair of horizontal plate portions 322 on the auxiliary wall (the surfaces opposite to the side where the vertical plate portions 321 are connected). On the other hand, a locking hole 333 capable of receiving the locking piece 324 is provided at a position where the locking wall 330 is aligned with the locking piece 324. The locking hole 333 is elongated in the front-rear direction (the direction along the fitting direction of the power-side connector with the vehicle-side connector 160), and allows the shielding wall 330 to move in the front-rear direction with respect to the auxiliary wall 320. ing. In a state where no force is applied to the plate spring 334, that is, in a state where the shielding wall 330 is urged by the plate spring 334 and moves forward, the locking piece 324 is abutted against the hole edge of the locking hole 333. Thus, the shielding wall 330 can be prevented from coming off forward.

　この電源側コネクタ３１０と嵌合される車両側コネクタ１６０の構成は、実施形態２と同様であるので、同一の符号を付して説明を省略する。 (Vehicle side connector 160)
Since the configuration of the vehicle-side connector 160 fitted to the power-side connector 310 is the same as that of the second embodiment, the same reference numerals are given and the description thereof is omitted.
（電源側コネクタ３１０の車両側コネクタ１６０からの離脱動作）
　次に、以上のように構成された電源側コネクタ３１０が、車両側コネクタ１６０から離脱する際の動作について説明する。 (Removal operation of power supply side connector 310 from vehicle side connector 160)
Next, the operation when the power supply side connector 310 configured as described above is detached from the vehicle side connector 160 will be described.
　電源側コネクタ３１０と車両側コネクタ１６０とが嵌合した状態では、電源側フード部３１３の内部に車両側フード部１６３が収容され、電源側端子収容部３１５の内部に車両側端子収容部１６５が収容されている。そして、車両側給電用端子１６８と電源側給電用端子１５０とが電気的に接続されている。 In a state where the power supply side connector 310 and the vehicle side connector 160 are fitted, the vehicle side hood portion 163 is accommodated inside the power supply side hood portion 313, and the vehicle side terminal accommodation portion 165 is located inside the power supply side terminal accommodation portion 315. Contained. The vehicle-side power supply terminal 168 and the power supply-side power supply terminal 150 are electrically connected.
　このとき、電源側タワー部３１４の連結部３１６が、２つの車両側端子収容部１６５の隙間に進入し、その先端が車両側フード部１６３の奥壁（車両側ハウジング本体１６２の前端面１６２Ａ）に突き当てられている。これにより、遮蔽壁３３０は、車両側ハウジング本体１６２の前端面１６２Ａに押圧されて、板バネ３３４を圧縮しつつ、その後端が電源側フード部３１３の奥壁（電源側ハウジング本体３１２の前端面３１２Ａ）に当接する位置（退避位置）まで押し込まれている。 At this time, the connecting portion 316 of the power supply side tower portion 314 enters the gap between the two vehicle side terminal accommodating portions 165, and the tip thereof is the rear wall of the vehicle side hood portion 163 (the front end surface 162A of the vehicle side housing body 162). Has been hit. As a result, the shielding wall 330 is pressed against the front end surface 162A of the vehicle-side housing main body 162 and compresses the leaf spring 334, while its rear end is the rear wall of the power-side hood portion 313 (the front end surface of the power-side housing main body 312). 312A) is pushed to the position (retracted position).
　電源側コネクタ３１０の離脱が開始されると、電源側コネクタ３１０の引き抜き動作に伴い、車両側コネクタ１６０が電源側コネクタ３１０に対して相対的に後退していく。このとき、車両側ハウジング本体１６２の前端面１６２Ａも、遮蔽壁３３０に対して相対的に後退していく。すると、板バネ３３４の付勢力により、遮蔽壁３３０が前進していく。 When the disconnection of the power supply side connector 310 is started, the vehicle side connector 160 moves backward relative to the power supply side connector 310 with the pulling operation of the power supply side connector 310. At this time, the front end surface 162 </ b> A of the vehicle-side housing body 162 is also retracted relative to the shielding wall 330. Then, the shielding wall 330 moves forward by the urging force of the leaf spring 334.
　電源側コネクタ３１０の離脱が進むと、電源側給電用端子１５０と車両側給電用端子１６８との接続が解除される。ここで、誤って充電中に電源側コネクタ３１０が車両側コネクタ１６０から引き抜かれるなどした場合には、隣り合う電源側給電用端子１５０間にアーク放電が発生することがある。 When the power supply side connector 310 is removed, the connection between the power supply side power supply terminal 150 and the vehicle side power supply terminal 168 is released. Here, when the power supply side connector 310 is accidentally pulled out of the vehicle side connector 160 during charging, arc discharge may occur between the adjacent power supply side power supply terminals 150.
　しかし、このとき、遮蔽壁３３０が電源側ハウジング本体３１２の前端面３１３Ａに当接する位置（退避位置）よりも前方位置（遮蔽位置）にある。この状態では遮蔽壁３３０の前端位置が、電源側給電用端子１５０の先端位置よりも前方（電源側コネクタ３１０との嵌合面側）にあり、隣り合う電源側給電用端子１５０の間に遮蔽壁３３０が介在する状態となる。この状態では、隣り合う電源側給電用端子１５０同士の先端部の空間距離が、突出した遮蔽壁３３０を回り込まなければならない分長くなる。このため、アーク放電を抑制することができる。 However, at this time, the shielding wall 330 is at a position (shielding position) in front of the position (retracted position) where it comes into contact with the front end surface 313A of the power supply side housing body 312. In this state, the front end position of the shielding wall 330 is in front of the front end position of the power supply side power supply terminal 150 (on the side of the fitting surface with the power supply side connector 310) and is shielded between the adjacent power supply side power supply terminals 150. The wall 330 is interposed. In this state, the spatial distance between the tip portions of the adjacent power supply side power supply terminals 150 becomes longer due to having to go around the protruding shielding wall 330. For this reason, arc discharge can be suppressed.
　また、遮蔽壁３３０が前方に移動することにより、遮蔽壁３３０の後端面と電源側ハウジング本体３１２の前端面３１３Ａとの間には隙間ができる。しかし、電源側ハウジング本体３１２の前端面３１２Ａには、補助壁３２０が立設されており、この補助壁３２０によって隣り合う電源側給電用端子１５０が隔てられる。これにより、隣り合う端子１５０間で短絡が生じることが防止される。 Further, since the shielding wall 330 moves forward, a gap is formed between the rear end surface of the shielding wall 330 and the front end surface 313A of the power supply side housing body 312. However, an auxiliary wall 320 is erected on the front end surface 312A of the power supply side housing body 312, and the adjacent power supply side power supply terminals 150 are separated by the auxiliary wall 320. This prevents a short circuit from occurring between adjacent terminals 150.
　さらに離脱が進むと、電源側フード部３１３の先端が車両側フード部１６３の先端から充分に離れた状態となり、電源側コネクタ３１０の車両側コネクタ１６０からの離脱が完了する。 When the detachment further proceeds, the tip of the power supply side hood portion 313 is sufficiently separated from the tip of the vehicle side hood portion 163, and the release of the power supply side connector 310 from the vehicle side connector 160 is completed.
（まとめ）
　以上のように本実施形態によれば、実施形態２と同様の作用効果が奏される。加えて、電源側ハウジング３１１の前端面３１１Ａ（遮蔽壁３３０に対向する面）に、隣り合う電源側給電用端子１５０の間を仕切る補助壁３２０が設けられている。上記の構成によれば、遮蔽壁３３０の前進に伴って、遮蔽壁３３０の後端で隣り合う電源側給電用端子１５０間に隙間が生じることを回避できる。これにより、隣り合う電源側給電用端子１５０同士が短絡することを防止できる。 (Summary)
As described above, according to the present embodiment, the same effects as those of the second embodiment can be obtained. In addition, an auxiliary wall 320 that partitions between adjacent power supply terminals 150 is provided on the front end surface 311A of the power supply housing 311 (the surface facing the shielding wall 330). According to said structure, it can avoid that a clearance gap produces between the power supply side electric power feeding terminals 150 adjacent in the rear end of the shielding wall 330 with the advance of the shielding wall 330. FIG. Thereby, it is possible to prevent the adjacent power supply terminals 150 from being short-circuited.

（電源側コネクタ４１０）
　電源側コネクタ４１０は、充電用の電力を供給するための給電装置に備えられるものであって、合成樹脂製によって形成された電源側ハウジング４１１（ハウジングに該当）を備える。この電源側ハウジング４１１は、横長ブロック状の電源側ハウジング本体４１２と、この電源側ハウジング本体４１２の前端面から前方に突出する筒状の電源側フード部４１３とを備える。 (Power supply side connector 410)

The front end position of each power supply side terminal accommodating portion 415 is substantially the same position as the front end position of the power supply side hood portion 413.
　電源側ハウジング本体４１２において２つの電源側端子収容部４１５と整合する位置には、実施形態２と同様に貫通孔４１７が設けられている。この貫通孔４１７と電源側端子収容部４１５の内部空間とが電源側端子収容孔４１８を形成する。この電源側端子収容孔４１８には、電源側給電用端子１５０が収容されている。電源側給電用端子１５０の構成は、実施形態２と同様であるので、同一の符号を付して説明を省略する。 A through-hole 417 is provided in the power supply side housing body 412 at a position aligned with the two power supply side terminal accommodating portions 415 as in the second embodiment. The through hole 417 and the internal space of the power supply side terminal accommodating portion 415 form a power supply side terminal accommodating hole 418.

Since the configuration of the power supply side power supply terminal 150 is the same as that of the second embodiment, the same reference numerals are given and description thereof is omitted.
　電源側ハウジング本体４１２の前端面４１２Ａには、補助壁３２０が立設されている。この補助壁３２０は、電源側タワー部４１４に整合する位置であって、隣り合う電源側給電用端子１５０を隔てる位置に形成されている。一方、電源側タワー部４１４の後端面において、この補助壁３２０に整合する位置には、補助壁収容孔３３１が設けられている。この補助壁収容孔３３１には、補助壁３２０および板バネ３３４が収容されている。補助壁３２０、補助壁収容孔３３１および板バネ３３４の構成は、実施形態４と同様であるので、同一の符号を付して説明を省略する。 The auxiliary wall 320 is erected on the front end surface 412A of the power source side housing body 412. The auxiliary wall 320 is formed at a position that aligns with the power supply side tower portion 414 and that separates the adjacent power supply side power supply terminals 150. On the other hand, an auxiliary wall accommodation hole 331 is provided at a position aligned with the auxiliary wall 320 on the rear end surface of the power supply side tower portion 414.

（車両側コネクタ１６０）
　この電源側コネクタ４１０と嵌合される車両側コネクタ１６０の構成は、実施形態２と同様であるので、同一の符号を付して説明を省略する。 (Vehicle side connector 160)
Since the configuration of the vehicle-side connector 160 fitted to the power-side connector 410 is the same as that of the second embodiment, the same reference numerals are given and description thereof is omitted.
（電源側コネクタ４１０の車両側コネクタ１６０からの離脱動作）
　次に、以上のように構成された電源側コネクタ４１０が、車両側コネクタ１６０から離脱する際の動作について説明する。 (Removal operation of power supply side connector 410 from vehicle side connector 160)
Next, the operation when the power supply side connector 410 configured as described above is detached from the vehicle side connector 160 will be described.
　電源側コネクタ４１０と車両側コネクタ１６０とが嵌合した状態では、電源側フード部４１３の内部に車両側フード部１６３が収容され、電源側端子収容部４１５の内部に車両側端子収容部１６５が収容されている。そして、車両側給電用端子１６８と電源側給電用端子１５０とが電気的に接続されている。 In a state where the power supply side connector 410 and the vehicle side connector 160 are fitted, the vehicle side hood portion 163 is accommodated inside the power supply side hood portion 413, and the vehicle side terminal accommodation portion 165 is located inside the power supply side terminal accommodation portion 415. Contained. The vehicle-side power supply terminal 168 and the power supply-side power supply terminal 150 are electrically connected.
　このとき、電源側タワー部４１４が、電源側フード部４１３と２つの車両側端子収容部１６５の隙間に進入し、その先端が車両側フード部１６３の奥壁（車両側ハウジング本体１６２の前端面１６２Ａ）に突き当てられている。これにより、電源側タワー部４１４は、車両側ハウジング本体１６２の前端面１６２Ａに押圧されて、板バネ３３４を圧縮しつつ、その後端が電源側フード部４１３の奥壁（電源側ハウジング本体４１２の前端面４１２Ａ）に当接する位置（退避位置）まで押し込まれている。 At this time, the power supply side tower portion 414 enters the gap between the power supply side hood portion 413 and the two vehicle side terminal accommodating portions 165, and the tip thereof is the rear wall of the vehicle side hood portion 163 (the front end surface of the vehicle side housing body 162). 162A). As a result, the power-side tower 414 is pressed against the front end face 162A of the vehicle-side housing body 162 and compresses the leaf spring 334, while its rear end is the back wall of the power-side hood 413 (the power-side housing body 412). It is pushed in to the position (retracted position) that contacts the front end surface 412A).
　電源側コネクタ４１０の離脱が開始されると、電源側コネクタ４１０の引き抜き動作に伴い、車両側コネクタ１６０が電源側コネクタ４１０に対して相対的に後退していく。このとき、車両側ハウジング本体１６２の前端面１６２Ａも、電源側タワー部４１４に対して相対的に後退していく。すると、板バネ３３４の付勢力により、電源側タワー部４１４が前進していく。 When the disconnection of the power supply side connector 410 is started, the vehicle side connector 160 moves backward relative to the power supply side connector 410 along with the pulling out operation of the power supply side connector 410. At this time, the front end surface 162 </ b> A of the vehicle-side housing main body 162 also moves backward relative to the power-side tower portion 414. Then, the power source side tower portion 414 moves forward by the urging force of the leaf spring 334.
　電源側コネクタ４１０の離脱が進むと、電源側給電用端子１５０と車両側給電用端子１６８との接続が解除される。ここで、誤って充電中に電源側コネクタ４１０が車両側コネクタ１６０から引き抜かれるなどした場合には、隣り合う電源側給電用端子１５０間にアーク放電が発生することがある。 When the power supply side connector 410 is removed, the connection between the power supply side power supply terminal 150 and the vehicle side power supply terminal 168 is released. Here, when the power supply side connector 410 is accidentally pulled out from the vehicle side connector 160 during charging, an arc discharge may occur between the adjacent power supply side power supply terminals 150.
　しかし、このとき、電源側タワー部４１４が電源側ハウジング本体４１２の前端面４１２Ａに当接する位置（退避位置）よりも前方位置（遮蔽位置）にある。この状態では電源側タワー部４１４の前端位置が、電源側給電用端子１５０の先端位置よりも前方（電源側コネクタ４１０との嵌合面側）にあり、隣り合う電源側給電用端子１５０の間に介在する状態となる。この状態では、隣り合う電源側給電用端子１５０同士の先端部の空間距離が、突出した電源側タワー部４１４を回り込まなければならない分長くなる。このため、アーク放電を抑制することができる。 However, at this time, the power supply side tower portion 414 is at a front position (shielding position) with respect to a position (retracted position) where it abuts against the front end surface 412A of the power supply side housing body 412. In this state, the front end position of the power supply side tower portion 414 is in front of the front end position of the power supply side power supply terminal 150 (the fitting surface side with the power supply side connector 410), and between the adjacent power supply side power supply terminals 150. It will be in the state which intervenes. In this state, the spatial distance between the front end portions of the adjacent power supply side power supply terminals 150 becomes longer due to having to go around the protruding power supply side tower portion 414. For this reason, arc discharge can be suppressed.
　また、電源側タワー部４１４が前方に移動することにより、電源側タワー部４１４の後端面と電源側ハウジング本体４１２の前端面４１２Ａとの間には隙間ができる。しかし、電源側ハウジング本体４１２の前端面４１２Ａには、補助壁３２０が立設されており、この補助壁３２０によって隣り合う電源側給電用端子１５０が隔てられる。これにより、隣り合う端子１５０間で短絡が生じることが防止される。 Further, when the power supply side tower part 414 moves forward, a gap is formed between the rear end face of the power supply side tower part 414 and the front end face 412A of the power supply side housing body 412. However, an auxiliary wall 320 is erected on the front end surface 412A of the power supply side housing body 412, and the adjacent power supply side power supply terminals 150 are separated by the auxiliary wall 320. This prevents a short circuit from occurring between adjacent terminals 150.
　さらに離脱が進むと、電源側フード部４１３の先端が車両側フード部１６３の先端から充分に離れた状態となり、電源側コネクタ４１０の車両側コネクタ１６０からの離脱が完了する。 When the detachment further proceeds, the tip of the power supply side hood portion 413 is sufficiently separated from the tip of the vehicle side hood portion 163, and the release of the power supply side connector 410 from the vehicle side connector 160 is completed.
（まとめ）
　以上のように本実施形態によれば、実施形態２と同様の作用効果が奏される。加えて、電源側タワー部４１４が、電源側給電用端子１５０の周囲を全周にわたって囲うものであり、この電源側タワー部４１４全体が圧縮コイルばね１５０によって前方へ付勢される。このような構成によれば、アークが電源側タワー部４１４の側方から回り込んで隣接する車両側給電用端子１６８に達することを防止できる。これにより、アーク放電をより効果的に抑制することができる。 (Summary)
As described above, according to the present embodiment, the same effects as those of the second embodiment can be obtained. In addition, the power supply side tower portion 414 surrounds the entire periphery of the power supply side power supply terminal 150, and the entire power supply side tower portion 414 is biased forward by the compression coil spring 150. According to such a configuration, it is possible to prevent the arc from wrapping around from the side of the power supply side tower unit 414 and reaching the adjacent vehicle side power supply terminal 168. Thereby, arc discharge can be suppressed more effectively.
　さらに、電源側ハウジング本体４１２の前端面４１２Ａにおいて電源側タワー部４１４に対向する面に、隣り合う電源側給電用端子１５０の間を仕切る補助壁３２０が設けられている。上記の構成によれば、電源側タワー部４１４の前進に伴って、電源側タワー部４１４の後端で隣り合う電源側給電用端子１５０間に隙間が生じることを回避できる。これにより、隣り合う電源側給電用端子１５０同士が短絡することを防止できる。 Further, an auxiliary wall 320 for partitioning between adjacent power supply terminals 150 is provided on a surface of the front end surface 412A of the power supply housing body 412 that faces the power supply tower 414. According to said structure, it can avoid that a clearance gap produces between the power supply side electric power feeding terminals 150 adjacent in the rear end of the power supply side tower part 414 with advance of the power supply side tower part 414.
