Description

充電用コネクタCharging connector
　本明細書によって開示される技術は、充電用コネクタに関する。 The technology disclosed in this specification relates to a charging connector.
　例えば、電気自動車などの車両に搭載されたバッテリ装置を充電するために、車両に設けられた車両側コネクタに嵌合される充電用コネクタとして特開２０１０－１２３５２１号公報（下記特許文献１）に記載のものが知られている。 For example, Japanese Patent Application Laid-Open No. 2010-123521 (Patent Document 1) discloses a charging connector that is fitted to a vehicle-side connector provided in a vehicle in order to charge a battery device mounted on a vehicle such as an electric vehicle. The ones described are known.
　この充電用コネクタは、充電器に接続された電線が内部に導入されるハウジングを有しており、ハウジングにおいて電線が導入される電線導入部には、電線に外嵌される合成樹脂製の電線保護部材（ケーブルプロテクタ）が装着されている。
　この電線保護部材は、ハウジングの電線導入部から露出した部分が、ブッシュ部とされており、このブッシュ部は、複数の環状をなす円環部と、隣り合う円環部との間に設けられた溝部と、溝部において隣り合う円環部を電線の延び方向に連結するように設けられた連結リブとを備えて構成されている。 This charging connector has a housing into which an electric wire connected to a charger is introduced, and an electric wire made of a synthetic resin that is externally fitted to the electric wire is introduced into the electric wire introduction portion where the electric wire is introduced into the housing. A protective member (cable protector) is attached.
In this electric wire protection member, a portion exposed from the electric wire introduction portion of the housing is a bush portion, and this bush portion is provided between a plurality of annular portions and adjacent annular portions. And a connecting rib provided so as to connect the annular portions adjacent to each other in the extending direction of the electric wire.
特開２０１０－１２３５２１号公報JP 2010-123521 A
　ところで、上記の電線保護部材は、連結リブが、ブッシュ部の全長に亘って電線の延び方向に延びた形態とされているため、電線が引っ張られたり、曲げられたりすると、ブッシュ部において、連結リブが設けられた部分は変形しく難くなっているものの、連結リブがない部分は、大きく変形する。このため、電線がブッシュ部を中心に小径に曲げられたり、頻繁に曲げられたりすると、連結リブがない部分にのみ応力が集中して電線の曲げに方向性が出てしまい、電線保護部材が破損し易くなってしまう。 By the way, the above-mentioned electric wire protection member has a configuration in which the connecting rib extends in the extending direction of the electric wire over the entire length of the bush portion, so that when the electric wire is pulled or bent, the connecting portion is connected in the bush portion. Although the portion provided with the rib is difficult to deform, the portion without the connecting rib is greatly deformed. For this reason, if the electric wire is bent to a small diameter around the bush portion or frequently bent, the stress concentrates only on the portion where there is no connecting rib, and the direction of the bending of the electric wire appears. It becomes easy to break.
　本明細書では、電線保護部材や電線が破損することを抑制する技術を開示する。 This specification discloses a technique for suppressing the breakage of the wire protection member and the wire.
　本明細書によって開示される技術は、車両に搭載されたバッテリ装置を充電するための充電用コネクタであって、電線が導入されるハウジングと、前記電線に外嵌された状態で前記ハウジングに装着される電線保護部材とを備え、前記電線保護部材は、フランジ状をなすフランジ部と、前記フランジ部よりも小径の小径筒部とを前記電線の延び方向に複数交互に配したブッシュ部を有しており、前記小径筒部は、隣り合う前記フランジ部との間に全周に亘って隙間を設けるように隣り合う前記フランジ部に連なっており、前記フランジ部は、前記ハウジングに近づくほど前記電線の延び方向の厚さ寸法が大きくなるように設定されている構成とした。 The technology disclosed in this specification is a charging connector for charging a battery device mounted on a vehicle, and is mounted on the housing in a state in which the electric wire is introduced and the electric wire is externally fitted to the housing. The wire protection member includes a bush portion in which a flange portion having a flange shape and a plurality of small-diameter cylindrical portions having a smaller diameter than the flange portion are alternately arranged in the extending direction of the wire. The small-diameter cylindrical portion is connected to the adjacent flange portion so as to provide a gap over the entire circumference between the adjacent flange portions, and the flange portion becomes closer to the housing as the housing is closer to the housing. It was set as the structure set so that the thickness dimension of the extension direction of an electric wire might become large.
　このような構成の充電用コネクタによると、電線保護部材のブッシュ部では、隣り合うフランジ部の間が全周に亘って溝状に凹んだ溝部となっているから、ハウジングから引き出された電線が曲げられた際に、電線の曲げに方向性が生じることを抑制することができる。 According to the charging connector having such a configuration, in the bush portion of the wire protection member, the gap between the adjacent flange portions is a groove portion that is recessed in a groove shape over the entire circumference. When bent, it is possible to suppress the occurrence of directivity in the bending of the electric wire.
　また、ブッシュ部では、ハウジングに近づくほどフランジ部の厚さ寸法が大きくなっており、ハウジングから離れた電線は、小径に曲がり易くなっているものの、ハウジングに近づくほど小径に曲がり難くなっているから、例えば、フランジ部の厚み寸法が全て同一のものに比べて、ハウジングから引き出された直後の電線が小径に曲げられることを抑制することができる。 Also, in the bush part, the thickness dimension of the flange part becomes larger as it gets closer to the housing, and although the electric wire away from the housing is easily bent to a small diameter, it becomes difficult to bend to a small diameter as it gets closer to the housing. For example, compared with the thing with the same thickness dimension of a flange part, it can suppress that the electric wire immediately after being pulled out from the housing is bent to a small diameter.
　つまり、ハウジングから離れた部分において電線の曲げ性を確保しつつ、ハウジングに近づくにつれて電線が徐々に小径に曲がり難くなり、ハウジングに最も近い部分では、電線が小径に曲がることを抑制することで電線がハウジングと干渉することを抑制することができる。これにより、電線保護部材が破損することを抑制することができ、ひいては電線が断線してしまうことを防ぐことができる。 In other words, while securing the bendability of the electric wire at a portion away from the housing, the electric wire gradually becomes difficult to bend to a smaller diameter as it approaches the housing, and at the portion closest to the housing, the electric wire is prevented from being bent to a smaller diameter. Can be prevented from interfering with the housing. Thereby, it can suppress that an electric wire protection member is damaged, and can prevent that an electric wire will break by extension.
　本明細書によって開示される充電用コネクタは、以下の構成としてもよい。
　前記フランジ部は、円盤状をなし、前記ブッシュ部が曲げられた状態では、隣り合う前記フランジ部において互いに隣り合う外周縁の一端部が当接する構成としてもよい。 The charging connector disclosed in the present specification may have the following configuration.
The flange portion may have a disk shape, and in a state where the bush portion is bent, one end portions of the outer peripheral edges adjacent to each other in the adjacent flange portions may be in contact with each other.
　このような構成によると、フランジ部が円盤状をなしているから、例えば、フランジ部が略矩形平板状に形成されている場合に比べて、電線の曲げに方向性が生じることをさらに抑制することができる。
　また、ブッシュ部が曲げられると、隣り合うフランジ部において互いに隣り合う外周縁の一端部が当接するから、隣り合うフランジ部において互いに対向する対向面同士が面接触する場合に比べて、ブッシュ部が過度に曲げられることを抑制しつつ、ブッシュ部における曲げ性を確保することができる。 According to such a configuration, since the flange portion has a disk shape, for example, compared to the case where the flange portion is formed in a substantially rectangular flat plate shape, the occurrence of directivity in the bending of the electric wire is further suppressed. be able to.
Further, when the bush portion is bent, one end portion of the outer peripheral edge adjacent to each other in the adjacent flange portion comes into contact, so that the bush portion is compared with the case where the opposing surfaces facing each other in the adjacent flange portion are in surface contact with each other. While suppressing excessive bending, it is possible to ensure the bendability at the bush portion.
　本明細書によって開示される技術によれば、電線保護部材や電線が破損することを抑制することができる。 According to the technology disclosed in this specification, it is possible to suppress the breakage of the wire protection member and the wire.

　ハウジング２０は、合成樹脂製であって、半筒形をなす左右一対の半割ハウジング２１を有しており、例えば、一方の半割ハウジング２１に対して他方の半割ハウジング２１を側方から重ね合わせ、複数箇所（本実施形態では４箇所）をねじ２２によってねじ止めすることにより、筒形のガン形状に組み立てられるようになっている。 The housing 20 is made of a synthetic resin and has a pair of left and right half housings 21 each having a semi-cylindrical shape. For example, the other half housing 21 with respect to one half housing 21 from the side. By superimposing and screwing a plurality of locations (four locations in the present embodiment) with screws 22, they are assembled into a cylindrical gun shape.
　ハウジング２０の前端部は、車両側コネクタと嵌合可能な嵌合部２３とされている。嵌合部２３には、充電用コネクタ１０を使用しない場合に、ハウジング２０の下端部に取り付けられた保護キャップ２４が前方から取り付け可能とされており、保護キャップ２４によって嵌合部２３が塵埃などから保護されるようになっている。 The front end portion of the housing 20 is a fitting portion 23 that can be fitted to the vehicle-side connector. When the charging connector 10 is not used, a protective cap 24 attached to the lower end of the housing 20 can be attached to the fitting portion 23 from the front, and the fitting portion 23 is made dust or the like by the protective cap 24. It comes to be protected from.
　ハウジング２０の前端部における嵌合部２３の上方には、車両側コネクタと嵌合部２３とを正規の嵌合状態にロックするロックアーム２６が設けられている。
　このロックアーム２６は、ハウジング２０の前後方向略中央部における上端部に設けられた操作部２７を下方向に押圧操作することで、上方に揺動変位するようになっている。 A lock arm 26 that locks the vehicle-side connector and the fitting portion 23 in a proper fitting state is provided above the fitting portion 23 at the front end portion of the housing 20.
The lock arm 26 is configured to swing and displace upward by pressing down an operation portion 27 provided at an upper end portion of the housing 20 at a substantially central portion in the front-rear direction.
　電線保護部材３０は、図２から図６に示すように、ハウジング２０よりも柔軟性を有する合成樹脂によって前後に長い略円筒状に形成されており、電線保護部材３０の軸心と充電ケーブルＷの軸心とがほぼ同一となるように充電ケーブルＷに外嵌されている。なお、図１、図２および図７では、電線保護部材３０の説明の関係上、充電ケーブルＷの延び方向を前後方向として説明する。 As shown in FIGS. 2 to 6, the electric wire protection member 30 is formed in a substantially cylindrical shape that is longer in the front and rear directions by a synthetic resin that is more flexible than the housing 20, and the shaft center of the electric wire protection member 30 and the charging cable W Is externally fitted to the charging cable W so as to be substantially the same. 1, 2, and 7, the extending direction of the charging cable W will be described as the front-rear direction because of the description of the wire protection member 30.
　また、電線保護部材３０は、円盤状の基部３１と、ハウジング２０の電線導入部２５内に収容されて保持される保持部３２と、ハウジング２０の電線導入部２５から露出するようにして基部３１の後方に連設されたブッシュ部４０とを備えて構成されている。 Further, the wire protection member 30 is exposed from the disk-shaped base portion 31, the holding portion 32 received and held in the wire introduction portion 25 of the housing 20, and the base portion 31 so as to be exposed from the wire introduction portion 25 of the housing 20. And a bush portion 40 provided continuously behind the rear portion.
　ハウジング２０の電線導入部２５は、図２に示すように、電線保護部材３０の一部を収容可能な筒状に形成されている。電線導入部２５の内周面２５Ａには、一対の抜止部２８が周設されており、一対の抜止部２８は、電線導入部２５の内周面２５Ａから電線導入部２５内に向かって突出するリブ状に形成されている。 The electric wire introduction part 25 of the housing 20 is formed in the cylinder shape which can accommodate a part of electric wire protection member 30, as shown in FIG. A pair of retaining portions 28 are provided around the inner peripheral surface 25A of the wire introducing portion 25, and the pair of retaining portions 28 protrude from the inner peripheral surface 25A of the wire introducing portion 25 into the wire introducing portion 25. It is formed in a rib shape.
　一方、電線保護部材３０の保持部３２は、図２、図３および図６に示すように、基部３１のハウジング２０側である前方に連設されており、基部３１から前方に向かって、保持部小径筒部３３と保持部フランジ部３４とを充電ケーブルＷの延び方向である前後方向に交互に複数（本実施形態では、それぞれ２つずつ）並べた形態とされている。 On the other hand, as shown in FIGS. 2, 3, and 6, the holding portion 32 of the wire protection member 30 is connected to the front of the base portion 31 on the housing 20 side, and is held from the base portion 31 toward the front. A plurality of small-diameter cylindrical portions 33 and holding portion flange portions 34 are alternately arranged in the front-rear direction, which is the extending direction of the charging cable W (two in the present embodiment).
　各保持部フランジ部３４は、いずれもほぼ同じ外径の円盤状に形成されており、保持部フランジ部３４の前後方向の厚み寸法も、全てがほぼ同じ厚み寸法とされている。 Each holding portion flange portion 34 is formed in a disk shape having substantially the same outer diameter, and all of the thickness dimensions in the front-rear direction of the holding portion flange portion 34 are substantially the same.
　保持部小径筒部３３は、保持部フランジ部３４よりも小径で、かつ、充電ケーブルＷの外周面に沿うように円筒状に形成されている。また、保持部小径筒部３３の前後方向の長さ寸法は、電線導入部２５における抜止部２８の前後方向の長さ寸法とほぼ同じ長さ寸法とされており、保持部小径筒部３３と保持部フランジ部３４との径方向の長さ寸法の差は、電線導入部２５における抜止部２８の突出寸法とほぼ同じに設定されている。 The holding portion small diameter cylindrical portion 33 has a smaller diameter than the holding portion flange portion 34 and is formed in a cylindrical shape along the outer peripheral surface of the charging cable W. The length dimension in the front-rear direction of the holding portion small-diameter cylindrical portion 33 is substantially the same as the length dimension in the front-rear direction of the retaining portion 28 in the electric wire introduction portion 25. The difference in the length dimension in the radial direction from the holding portion flange portion 34 is set to be substantially the same as the protruding size of the retaining portion 28 in the electric wire introduction portion 25.
　したがって、前後に隣り合う保持部フランジ部３４の間は、前後に隣り合う保持部フランジ部３４と保持部小径筒部３３とによって、径方向内側に向かって凹んだ溝状の保持部溝部３５とされており、図２に示すように、この保持部溝部３５に電線導入部２５内の抜止部２８を嵌合させることで、電線導入部２５内に電線保護部材３０の保持部３２が前後方向に抜け止めされて保持されるようになっている。 Therefore, between the holding portion flange portions 34 adjacent to each other in the front-rear direction, a holding portion groove portion 35 that is recessed inward in the radial direction by the holding portion flange portion 34 and the holding portion small-diameter cylindrical portion 33 that are adjacent to the front and rear. As shown in FIG. 2, the holding portion 32 of the wire protection member 30 is moved in the front-rear direction by fitting the retaining portion 28 in the wire introduction portion 25 into the holding portion groove portion 35. It is designed to be held in place.
　ブッシュ部４０は、大まかには前方に向かうほど拡径される略円錐状をなしており、基部３１の後方に連設されている。また、ブッシュ部４０は、基部３１からブッシュ部小径筒部（「小径筒部」の一例）４１とブッシュ部フランジ部（「フランジ部」の一例）４２とを充電ケーブルＷの延び方向である前後方向に交互に複数（本実施形態では、それぞれ８つずつ）並べた形態とされている。 The bush portion 40 has a generally conical shape whose diameter is increased toward the front, and is continuously provided behind the base portion 31. In addition, the bush portion 40 includes a bush portion small-diameter cylindrical portion (an example of a “small-diameter cylindrical portion”) 41 and a bush portion flange portion (an example of a “flange portion”) 42 extending from the base portion 31 in the extending direction of the charging cable W. A plurality (in the present embodiment, 8 each) are alternately arranged in the direction.
　したがって、前後に隣り合うブッシュ部フランジ部４２の間には、前後に隣り合うブッシュ部フランジ部４２とブッシュ部小径筒部４１とによって、ブッシュ部フランジ部４２の外周面４２Ａの位置よりも径方向内側に向かって凹んだ溝状のブッシュ部溝部４３が全周に亘って構成され、前後に隣り合うブッシュ部フランジ部４２の間には全周に亘って隙間が設けられている。 Therefore, between the bush part flange parts 42 adjacent to the front and rear, the bush part flange part 42 and the bush part small-diameter cylindrical part 41 adjacent to the front and back are more radial than the position of the outer peripheral surface 42A of the bush part flange part 42. A groove-like bush portion groove portion 43 that is recessed toward the inside is formed over the entire circumference, and a gap is provided between the bush portion flange portions 42 adjacent to each other in the front and rear directions.
　つまり、充電ケーブルＷの曲げに伴って、図７に示すように、このブッシュ部溝部４３の一側の溝幅（隙間）が前後方向に小さく狭まると共に、ブッシュ部溝部４３の一側とは反対側の他側の溝幅（隙間）が前後方向に大きく広がることで、ブッシュ部４０が充電ケーブルＷと共に曲がるようになっている。 That is, as shown in FIG. 7, as the charging cable W is bent, the groove width (gap) on one side of the bush portion groove portion 43 is narrowed in the front-rear direction and is opposite to the one side of the bush portion groove portion 43. The bush portion 40 bends together with the charging cable W because the groove width (gap) on the other side greatly widens in the front-rear direction.
　なお、ブッシュ部小径筒部４１は、前側に配された３つのブッシュ部小径筒部４１が前後方向に最も長く、前側から４番目と５番目のブッシュ部小径筒部４１が前側３つに比べて前後方向にやや短く設定されている。そして、後側に配された２つのブッシュ部小径筒部４１が前後方向に最も短くなるように、ブッシュ部４０は前から４段階に亘って順次短くなるように設定されている。 In addition, the bush part small diameter cylinder part 41 has the three bush part small diameter cylinder parts 41 arranged on the front side being the longest in the front-rear direction, and the fourth and fifth bush part small diameter cylinder parts 41 from the front side compared to the three front sides. Is set slightly shorter in the front-rear direction. And the bush part 40 is set so that it may become short sequentially in four steps from the front so that the two bush part small diameter cylinder parts 41 distribute | arranged to the rear side may become the shortest in the front-back direction.
　さて、電線保護部材３０のブッシュ部４０における複数のブッシュ部フランジ部４２は、図２、図３および図６に示すように、前側に配されたブッシュ部フランジ部４２ほど前後方向の厚み寸法が大きく設定されており、いずれのブッシュ部フランジ部４２も隣り合うブッシュ部小径筒部４１よりも前後方向に長くなるように設定されている。 Now, as shown in FIGS. 2, 3, and 6, the plurality of bush portion flange portions 42 in the bush portion 40 of the wire protection member 30 have a thickness dimension in the front-rear direction as the bush portion flange portion 42 disposed on the front side. Each bush portion flange portion 42 is set to be longer in the front-rear direction than the adjacent bush portion small-diameter cylindrical portion 41.
　そして、ブッシュ部４０が充電ケーブルＷと共に曲げられると、隣り合うブッシュ部フランジ部４２における互いに隣り合う外周縁の一端部４２Ｂ同士が当接するようになっている。つまり、充電ケーブルＷと共にブッシュ部４０が曲げられると、図７に示すように、前後に並んだブッシュ部フランジ部４２の外周面４２Ａが略円弧状に連続した状態となり、ブッシュ部４０は、前方に向かうほど緩やかな円弧を描くようになっている。 When the bush portion 40 is bent together with the charging cable W, the adjacent one end portions 42B of the outer peripheral edges of the adjacent bush portion flange portions 42 come into contact with each other. That is, when the bush portion 40 is bent together with the charging cable W, as shown in FIG. 7, the outer peripheral surface 42A of the bush portion flange portion 42 arranged in the front-rear direction is continuous in a substantially arc shape, A gentle arc is drawn as it goes to.
　また、ブッシュ部小径筒部４１の前後両側の端縁部であるブッシュ部フランジ部４２との境界部分には、一対の拡幅部４４が設けられている。各拡幅部４４は、ブッシュ部フランジ部４２に向かうほどＲ状に拡幅された形態とされており、ブッシュ部フランジ部４２に連なる形態とされている。また、ブッシュ部４０の後端部（後方から２つめのブッシュ部小径筒部４１）よりも前方に配された各ブッシュ部小径筒部４１の一対の拡幅部４４の前後方向の長さ寸法の合計は、ブッシュ部小径筒部４１において一対の拡幅部４４の間に配された同径部４５の前後方向の長さ寸法とほぼ同じ大きさかそれよりも大きくなるように設定されている。 Further, a pair of widened portions 44 are provided at a boundary portion with the bush portion flange portion 42 which is an edge portion on both the front and rear sides of the bush portion small diameter cylindrical portion 41. Each widened portion 44 is configured to be widened in an R shape toward the bush portion flange portion 42, and is configured to be continuous with the bush portion flange portion 42. Further, the length dimension of the pair of widened portions 44 of each bushing portion small diameter cylindrical portion 41 arranged in front of the rear end portion of the bushing portion 40 (second bushing portion small diameter cylindrical portion 41 from the rear) is the longitudinal dimension. The total is set to be substantially the same as or larger than the length dimension in the front-rear direction of the same diameter portion 45 disposed between the pair of widened portions 44 in the bush portion small diameter cylindrical portion 41.
　したがって、ブッシュ部４０の後端部よりも前方のブッシュ部４０は、ブッシュ部小径筒部４１が曲がる際に、各拡幅部４４が各ブッシュ部小径筒部４１と各ブッシュ部フランジ部４２との間を補強しつつ、踏ん張るようになっている。これにより、ブッシュ部４０の後端部よりも前方の部分では、ブッシュ部４０が曲がる際に、ブッシュ部小径筒部４１とブッシュ部フランジ部４２との間に亀裂などが生じることを防ぐことができるようになっている。 Therefore, when the bush portion small-diameter cylindrical portion 41 is bent, the widened portion 44 is formed between the bush portion small-diameter cylindrical portion 41 and each bush portion flange portion 42 when the bush portion small-diameter cylindrical portion 41 is bent. It is designed to stand while reinforcing the gap. Thereby, in the part ahead of the rear-end part of the bush part 40, when the bush part 40 bends, it can prevent that a crack etc. arise between the bush part small diameter cylinder part 41 and the bush part flange part 42. It can be done.
　本実施形態は、以上のような構成であって、続いて、充電用コネクタ１０の作用および効果について説明する。
　本実施形態の充電用コネクタ１０は、車両に搭載されたバッテリ装置に充電する場合、保護キャップ２４を取り外し、車両に設けられた車両側コネクタに嵌合させて充電を行う。
　そして、充電の完了後には、充電用コネクタ１０を車両側コネクタから離脱させ、充電ケーブルＷを巻き取るなどして保管する。 The present embodiment is configured as described above. Next, the operation and effect of the charging connector 10 will be described.
When charging the battery device mounted on the vehicle, the charging connector 10 of the present embodiment is charged by removing the protective cap 24 and fitting it into a vehicle-side connector provided on the vehicle.
After the charging is completed, the charging connector 10 is detached from the vehicle side connector, and the charging cable W is wound up and stored.
　ここで、充電ケーブルＷを巻き取る際に、図７に示すように、充電ケーブルＷをハウジング２０の電線導入部２５から引き出された位置から小径に曲げたり、頻繁に曲げたりすると、電線導入部２５から引き出される位置において充電ケーブルＷとハウジング２０とが干渉することで、充電ケーブルＷの被覆が損傷してしまう。このため、電線導入部２５から充電ケーブルＷが引き出された部分には、充電ケーブルＷの外周を覆う電線保護部材３０が装着される。 Here, when winding the charging cable W, as shown in FIG. 7, if the charging cable W is bent to a small diameter or frequently bent from the position where the charging cable W is drawn from the electric wire introducing portion 25 of the housing 20, When the charging cable W and the housing 20 interfere with each other at the position where the charging cable W is pulled out, the coating of the charging cable W is damaged. For this reason, the electric wire protection member 30 which covers the outer periphery of the charging cable W is attached to the part where the charging cable W is pulled out from the electric wire introduction part 25.
　しかしながら、例えば、電線保護部材において充電ケーブルの曲げに方向性がある場合、充電ケーブルＷが小径に曲げられたり、頻繁に曲げられたりすると、電線保護部材の一部に曲げ応力が集中することで、電線保護部材が破損することが懸念される。 However, for example, when the charging cable is directional in the electric wire protection member, if the charging cable W is bent to a small diameter or frequently bent, bending stress concentrates on a part of the electric wire protection member. There is a concern that the wire protection member may be damaged.
　ところが、本実施形態によると、電線保護部材３０のブッシュ部４０では、隣り合うブッシュ部フランジ部４２の間には全周に亘って溝状に凹んだブッシュ部溝部４３が設けられており、隣り合うブッシュ部フランジ部４２の間には全周に亘って隙間が設けられているから、ハウジング２０の電線導入部２５から後方に引き出された充電ケーブルＷが曲げられた際に、充電ケーブルＷの曲げに方向性が生じることを抑制することができる。
　これにより、充電ケーブルＷの曲げに方向性が生じることに起因して、電線保護部材３０や充電ケーブルＷが破損することを抑制することができる。 However, according to the present embodiment, in the bush portion 40 of the wire protection member 30, the bush portion groove portion 43 that is recessed in a groove shape is provided between the adjacent bush portion flange portions 42. Since a gap is provided over the entire circumference between the matching bush portion flange portions 42, when the charging cable W drawn backward from the electric wire introduction portion 25 of the housing 20 is bent, the charging cable W It can suppress that directionality arises in bending.
Thereby, it can suppress that the electric wire protection member 30 and the charging cable W are damaged resulting from directionality in the bending of the charging cable W.
　また、本実施形態のブッシュ部４０では、図２、図３および図６に示すように、前方に向かうほど（ハウジング２０に近づくほど）ブッシュ部フランジ部４２の前後方向の板厚寸法が大きくなっているから、例えば、ブッシュ部フランジ部の板厚寸法が全て同一のものに比べて、電線導入部２５から離れたブッシュ部４０の後端部は、図７に示すように、充電ケーブルＷが小径に曲がるものの、ハウジング２０に近づくほど小径に曲がり難くなり、電線導入部２５から後方に引き出された直後の充電ケーブルＷは緩やか曲がるようになっている。 Moreover, in the bush part 40 of this embodiment, as shown to FIG.2, FIG.3 and FIG.6, the plate | board thickness dimension of the front-back direction of the bush part flange part 42 becomes large, so that it goes to the front (approaching the housing 20). Therefore, for example, as shown in FIG. 7, the charging cable W is connected to the rear end portion of the bush portion 40 away from the wire introduction portion 25 as compared with the case where the thickness of the bush portion flange portion is the same. Although it bends to a small diameter, it becomes difficult to bend to a small diameter as it approaches the housing 20, and the charging cable W immediately after being pulled backward from the electric wire introduction portion 25 is bent gently.
　つまり、ハウジング２０から離れた部分において充電ケーブルＷの曲げ性を確保しつつ、ハウジング２０の電線導入部２５に最も近い部分では、充電ケーブルＷを小径に曲がり難くすることで、充電ケーブルＷとハウジング２０の電線導入部２５とが干渉することを抑制することができる。これにより、充電ケーブルＷと電線導入部２５とが干渉することに起因して充電ケーブルＷが破損することを防ぐことができる。 That is, while ensuring the bendability of the charging cable W at a portion away from the housing 20, the charging cable W and the housing are made difficult to bend to a small diameter at the portion closest to the electric wire introduction portion 25 of the housing 20. It can suppress that 20 electric wire introduction parts 25 interfere. Thereby, it is possible to prevent the charging cable W from being damaged due to the interference between the charging cable W and the electric wire introduction portion 25.
　また、本実施形態によると、ブッシュ部４０が充電ケーブルＷと共に曲がる際には、前後に隣り合う円盤状のブッシュ部フランジ部４２における互いに隣り合う外周縁の一端部４２Ｂ同士が当接することで、図７に示すように、前後に並んだブッシュ部フランジ部４２の外周面４２Ａが略円弧状に連続した状態となり、ブッシュ部４０が前方に向かうほど緩やかな円弧を描くから、例えば、隣り合うフランジ部において前後に対向する面同士が面接触する場合に比べて、ブッシュ部４０における曲げ性を確保しつつ、ブッシュ部４０が過度に曲げられることをさらに抑制することができる。 Further, according to the present embodiment, when the bush portion 40 bends together with the charging cable W, the end portions 42B of the outer peripheral edges adjacent to each other in the disk-like bush portion flange portion 42 adjacent to each other in front and rear contact each other. As shown in FIG. 7, since the outer peripheral surface 42A of the bushing flange portion 42 arranged in the front-and-rear direction is continuous in a substantially arc shape, and the bushing portion 40 draws a gentle arc toward the front, for example, adjacent flanges Compared with the case where the front and rear surfaces facing each other in the portion are in surface contact, it is possible to further prevent the bush portion 40 from being bent excessively while ensuring the bendability in the bush portion 40.
　以上のように、本実施形態の充電用コネクタ１０によると、電線保護部材３０のブッシュ部４０において隣り合うブッシュ部フランジ部４２の間にブッシュ部小径筒部４１を配し、隣り合うブッシュ部フランジ部４２の間に全周に亘って溝状に凹んだブッシュ部溝部４３を設けているから、ハウジング２０から引き出された充電ケーブルＷが曲げられる際に、充電ケーブルＷの曲げに方向性が生じることを抑制することができる。これにより、充電ケーブルＷの曲げに方向性が生じることに起因して、電線保護部材３０や充電ケーブルＷが破損することを抑制することができる。 As described above, according to the charging connector 10 of the present embodiment, the bush portion small-diameter cylindrical portion 41 is arranged between the adjacent bush portion flange portions 42 in the bush portion 40 of the wire protection member 30, and the adjacent bush portion flanges. Since the bush part groove part 43 recessed in the groove shape is provided between the part 42 over the perimeter, when the charging cable W pulled out from the housing 20 is bent, directionality arises in the bending of the charging cable W. This can be suppressed. Thereby, it can suppress that the electric wire protection member 30 and the charging cable W are damaged resulting from directionality in the bending of the charging cable W.
　また、ブッシュ部４０は、ブッシュ部フランジ部４２の前後方向の板厚寸法をハウジング２０に近いほど大きくなるように設定することで、電線導入部２５に最も近い部分では、充電ケーブルＷを小径に曲がり難くし、さらに、充電ケーブルＷが曲げられた際には、前後に隣り合う円盤状のブッシュ部フランジ部４２における互いに隣り合う外周縁の一端部４２Ｂ同士を当接させることで、前方に向かうほど緩やかな円弧を描くようにしている。これにより、例えば、隣り合うフランジ部において前後に対向する面同士が面接触する場合に比べて、ブッシュ部４０における曲げ性を確保しつつ、ブッシュ部４０が過度に曲げられることをさらに抑制することができる。
　すなわち、充電ケーブルＷとハウジング２０とが干渉することに起因して充電ケーブルＷが破損することを防ぐことができるようになっている。 In addition, the bush portion 40 is set so that the thickness of the bush portion flange portion 42 in the front-rear direction increases as the distance from the housing 20 increases, so that the charging cable W has a small diameter at the portion closest to the electric wire introduction portion 25. Further, when the charging cable W is bent, when the charging cable W is bent, the front end portions 42B of the adjacent outer peripheral edges of the disc-shaped bush portion flange portions 42 that are adjacent to each other are brought into contact with each other. A gentle arc is drawn. Thereby, compared with the case where the front and back opposing surfaces in the adjacent flange portions are in surface contact, for example, the bending of the bush portion 40 is further suppressed while the bendability in the bush portion 40 is secured. Can do.
That is, it is possible to prevent the charging cable W from being damaged due to the interference between the charging cable W and the housing 20.
