［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。
本開示のコネクタホルダは、
［１］コネクタを収容する収容部と、前記収容部の上方を被覆する上方被覆部と、前記上方被覆部の縁部に沿って前記上方被覆部の上面に立設され、車体側に固定される固定壁部と、前記固定壁部を貫通し、前記上方被覆部の上部空間と前記上方被覆部の側方空間とを連通する排水孔と、前記排水孔に対して前記側方空間側である排水側で対向する対向壁部と、を備える。 [Explanation of Embodiments of the present disclosure]
First, embodiments of the present disclosure will be listed and described.
The connector holder of the present disclosure is
[1] An accommodating portion for accommodating a connector, an upper covering portion that covers the upper part of the accommodating portion, and an upper surface of the upper covering portion along the edge of the upper covering portion are erected and fixed to the vehicle body side. A drain hole that penetrates the fixed wall portion and communicates with the upper space of the upper covering portion and the side space of the upper covering portion, and a drain hole on the side space side with respect to the drain hole. It is provided with an opposing wall portion facing a certain drainage side.

この構成によれば、上方被覆部の縁部に立設した固定壁部によって、上方被覆部の縁部から収容部側に水が回り込むことを抑制でき、その結果、コネクタの被水を抑制することが可能となる。また、排水孔の排水側が対向壁部によって被覆されているため、コネクタホルダが排水孔の排水側（側方空間側）から被水したときに、水が排水孔を通って上方被覆部側（上部空間側）に逆流することを対向壁部によって抑制できる。これにより、収容部に収容されたコネクタへの被水を好適に防ぐことが可能となる。 According to this configuration, the fixed wall portion erected on the edge portion of the upper covering portion can prevent water from wrapping around from the edge portion of the upper covering portion to the accommodating portion side, and as a result, the water reception of the connector is suppressed. It becomes possible. Further, since the drainage side of the drainage hole is covered with the facing wall portion, when the connector holder is exposed to water from the drainage side (side space side) of the drainage hole, water passes through the drainage hole and is on the upper covering portion side (). Backflow to the upper space side) can be suppressed by the facing wall portion. This makes it possible to suitably prevent water from being applied to the connector housed in the housing unit.

［２］上記のコネクタホルダが、前記上方被覆部の前記縁部から延びて前記収容部の側方を被覆する側方被覆部と、前記対向壁部から延びて前記側方被覆部の外側面に対向する延長壁部、及び、前記側方被覆部における前記延長壁部に対向する部位を含む排水路と、を備えることが好ましい。この構成によれば、側方被覆部によってコネクタの被水を抑制できる。また、排水孔から排水されて対向壁部に付着した水を、排水路を通じて排水することができる。 [2] The connector holder extends from the edge portion of the upper covering portion to cover the side of the accommodating portion, and extends from the facing wall portion to cover the outer surface of the side covering portion. It is preferable to provide an extension wall portion facing the surface and a drainage channel including a portion of the side covering portion facing the extension wall portion. According to this configuration, the water contact of the connector can be suppressed by the side covering portion. Further, the water that has been drained from the drain hole and adhered to the facing wall portion can be drained through the drainage channel.

［３］車体への組付状態において、前記排水路の下端部が前記収容部よりも下側に位置することが好ましい。この構成によれば、排水路を通る水を、排水路の下端部から収容部の下方に排水することができ、その結果、収容部に収容されたコネクタの被水をより好適に抑制できる。 [3] It is preferable that the lower end of the drainage channel is located below the accommodating portion in the state of being assembled to the vehicle body. According to this configuration, the water passing through the drainage channel can be drained from the lower end of the drainage channel to the lower part of the accommodating portion, and as a result, the water coverage of the connector accommodated in the accommodating portion can be more preferably suppressed.

［４］上記のコネクタホルダが、前記上方被覆部の上面に立設され、前記固定壁部に繋がる立設壁部を備え、前記立設壁部と前記固定壁部が繋がる部位が角部をなしており、前記排水孔が前記角部に設けられていることが好ましい。この構成によれば、上方被覆部の上面に付着した水を、固定壁部及び立設壁部によって角部に案内することが可能となるため、角部に形成された排水孔からの排水を促進することが可能となる。 [4] The connector holder is erected on the upper surface of the upper covering portion, includes an erected wall portion connected to the fixed wall portion, and a portion connecting the erected wall portion and the fixed wall portion has a corner portion. It is preferable that the drainage hole is provided at the corner portion. According to this configuration, the water adhering to the upper surface of the upper covering portion can be guided to the corner portion by the fixed wall portion and the standing wall portion, so that the drainage from the drainage hole formed in the corner portion can be drained. It becomes possible to promote.

［５］また、本開示のワイヤハーネスは、上記のコネクタホルダと、前記コネクタホルダの前記収容部に収容されたコネクタと、前記コネクタに接続された電線と、を備える。
この構成によれば、排水孔の排水側が対向壁部によって被覆されているため、コネクタホルダが排水孔の排水側（側方空間側）から被水したときに、水が排水孔を通って上方被覆部側（上部空間側）に逆流することを対向壁部によって抑制できる。これにより、収容部に収容されたコネクタへの被水を好適に防ぐことが可能となる。 [5] Further, the wire harness of the present disclosure includes the above-mentioned connector holder, a connector housed in the said accommodating portion of the said connector holder, and an electric wire connected to the said connector.
According to this configuration, since the drainage side of the drainage hole is covered with the facing wall portion, when the connector holder is exposed to water from the drainage side (side space side) of the drainage hole, water flows upward through the drainage hole. Backflow to the covering portion side (upper space side) can be suppressed by the facing wall portion. This makes it possible to suitably prevent water from being applied to the connector housed in the housing unit.

As shown in FIGS. 1, 2 and 3, the connector holder 11 is, for example, an injection-molded product made of a synthetic resin material. In the drawing, the X-axis in the XYZ axes orthogonal to each other represents the depth direction X of the connector holder 11, the Y-axis represents the width direction Y of the connector holder 11, and the Z-axis represents the height direction Z of the connector holder 11. Represents. The connector holder 11 is fixed to the vehicle body via, for example, a metal bracket 14. The connector holder 11 is assembled to the vehicle body so that the height direction Z is inclined with respect to the vertical direction.

コネクタホルダ１１は、コネクタ１２を収容する収容部２１と、収容部２１の上方を被覆する上方被覆部２２と、収容部２１の側方を被覆する側方被覆部２３と、を備えている。上方被覆部２２及び側方被覆部２３は、収容部２１に収容されたコネクタ１２に対する水掛かりを抑制している。 The connector holder 11 includes an accommodating portion 21 accommodating the connector 12, an upper covering portion 22 covering the upper part of the accommodating portion 21, and a side covering portion 23 covering the side of the accommodating portion 21. The upper covering portion 22 and the side covering portion 23 suppress water splashing on the connector 12 accommodated in the accommodating portion 21.

図１、図２及び図３には、一対の雄・雌コネクタが嵌合された状態の４つのコネクタ１２が収容部２１に収容されている状態を示している。なお、図２及び図３では電線１３の図示を省略している。コネクタ１２の雄・雌コネクタは、コネクタホルダ１１の奥行方向Ｘに沿って収容部２１に組み付けられている。また、電線１３は、コネクタ１２から奥行方向Ｘに沿って引き出されている。側方被覆部２３は、コネクタ１２の組付方向（言い換えると、コネクタ１２に接続された電線１３の長さ方向）と直交する側方を被覆している。 FIGS. 1, 2 and 3 show a state in which four connectors 12 in which a pair of male and female connectors are fitted are accommodated in the accommodating portion 21. Note that the electric wire 13 is not shown in FIGS. 2 and 3. The male / female connectors of the connector 12 are assembled to the accommodating portion 21 along the depth direction X of the connector holder 11. Further, the electric wire 13 is drawn out from the connector 12 along the depth direction X. The side covering portion 23 covers the side orthogonal to the assembling direction of the connector 12 (in other words, the length direction of the electric wire 13 connected to the connector 12).

（上方被覆部２２及び側方被覆部２３）
図２に示すように、コネクタホルダ１１の奥行方向Ｘから見て、上方被覆部２２と側方被覆部２３とは、互いにＬ字状に略直交するように形成されている。上方被覆部２２は、幅方向Ｙにおいて収容部２１よりも広い大きさに形成されている。また、上方被覆部２２は、平面視（上方視）において略長方形状をなす（図４参照）。上方被覆部２２の大部分は、高さ方向Ｚと直交する略平面状（すなわちＸＹ平面と平行な略平面状）をなしている。コネクタホルダ１１が車体に組み付けられた状態においては、上方被覆部２２は、鉛直方向に対して傾斜するようになっている。 (Upper covering portion 22 and side covering portion 23)
As shown in FIG. 2, when viewed from the depth direction X of the connector holder 11, the upper covering portion 22 and the side covering portion 23 are formed so as to be substantially orthogonal to each other in an L shape. The upper covering portion 22 is formed to have a size wider than that of the accommodating portion 21 in the width direction Y. Further, the upper covering portion 22 has a substantially rectangular shape in a plan view (upward view) (see FIG. 4). Most of the upper covering portion 22 has a substantially planar shape (that is, a substantially planar shape parallel to the XY plane) perpendicular to the height direction Z. When the connector holder 11 is assembled to the vehicle body, the upper covering portion 22 is inclined with respect to the vertical direction.

図３に示すように、上方被覆部２２は、奥行方向Ｘにおいて収容部２１よりも広い大きさに形成されている。側方被覆部２３も同様に、奥行方向Ｘにおいて収容部２１よりも広い大きさに形成されている。側方被覆部２３は、上方被覆部２２の幅方向Ｙの縁部２２ａに対して略直角をなすように繋がっている。側方被覆部２３の大部分は、幅方向Ｙと直交する略平面状（すなわちＸＺ平面と平行な略平面状）をなしている。そして、側方被覆部２３は、収容部２１の幅方向Ｙの側方を被覆する。 As shown in FIG. 3, the upper covering portion 22 is formed to have a size wider than that of the accommodating portion 21 in the depth direction X. Similarly, the side covering portion 23 is formed to have a size wider than that of the accommodating portion 21 in the depth direction X. The side covering portion 23 is connected so as to form a substantially right angle to the edge portion 22a of the upper covering portion 22 in the width direction Y. Most of the side covering portion 23 has a substantially planar shape (that is, a substantially planar shape parallel to the XZ plane) perpendicular to the width direction Y. Then, the side covering portion 23 covers the side of the accommodating portion 21 in the width direction Y.

（固定壁部２４）
図１〜図３に示すように、上方被覆部２２の上面には、固定壁部２４が立設されている。固定壁部２４は、上方被覆部２２の縁部２２ａに沿って設けられている。また、固定壁部２４は、上方被覆部２２の上面の垂直方向（すなわち高さ方向Ｚ）に対して傾斜している。固定壁部２４はブラケット１４を介して車体（ピラーツーピラーメンバ）に固定される。ピラーツーピラーメンバの上方には、エアコンディショナに接続される空調用ダクトなどが位置している。ブラケット１４のピラーツーピラーメンバに当接する上端部は、車幅方向に延出するフランジ状に形成されている。すなわち、例えば結露などによって空調用ダクトの表面に付着した水がピラーツーピラーメンバに落下し、そのピラーツーピラーメンバに付着した水は、ブラケット１４を伝ってコネクタホルダ１１の上方被覆部２２に流れるようになっている。 (Fixed wall part 24)
As shown in FIGS. 1 to 3, a fixed wall portion 24 is erected on the upper surface of the upper covering portion 22. The fixed wall portion 24 is provided along the edge portion 22a of the upper covering portion 22. Further, the fixed wall portion 24 is inclined with respect to the vertical direction (that is, the height direction Z) of the upper surface of the upper covering portion 22. The fixed wall portion 24 is fixed to the vehicle body (pillar-to-pillar member) via the bracket 14. Above the pillar-to-pillar member, an air-conditioning duct connected to the air-conditioning conditioner is located. The upper end portion of the bracket 14 that abuts on the pillar-to-pillar member is formed in a flange shape that extends in the vehicle width direction. That is, for example, water adhering to the surface of the air conditioning duct due to dew condensation falls on the pillar-to-pillar member, and the water adhering to the pillar-to-pillar member flows through the bracket 14 to the upper covering portion 22 of the connector holder 11. It has become like.

図１に示すように、固定壁部２４の上方被覆部２２側にブラケット１４が配置され、固定壁部２４とブラケット１４がボルト１５及びナット１６によって締結固定される。なお、固定壁部２４には、ボルト１５が挿通される例えば金属製のカラー１７を収容するカラー収容部２５が形成されている（図３参照）。また、固定壁部２４には、固定壁部２４を厚さ方向に貫通する排水孔２６が形成されている。なお、以下の説明では、固定壁部２４における上方被覆部２２側の側面を固定壁部２４の表面と言い、その反対側の側面を固定壁部２４の裏面と言う場合がある。 As shown in FIG. 1, a bracket 14 is arranged on the upper covering portion 22 side of the fixed wall portion 24, and the fixed wall portion 24 and the bracket 14 are fastened and fixed by bolts 15 and nuts 16. The fixed wall portion 24 is formed with a collar accommodating portion 25 for accommodating, for example, a metal collar 17 through which the bolt 15 is inserted (see FIG. 3). Further, the fixed wall portion 24 is formed with a drain hole 26 that penetrates the fixed wall portion 24 in the thickness direction. In the following description, the side surface of the fixed wall portion 24 on the upper covering portion 22 side may be referred to as the front surface of the fixed wall portion 24, and the side surface on the opposite side thereof may be referred to as the back surface of the fixed wall portion 24.

（立設壁部３１）
図３及び図４に示すように、上方被覆部２２の上面には、固定壁部２４の他に立設壁部３１が立設されている。立設壁部３１は、固定壁部２４が形成された前記縁部２２ａに交わる上方被覆部２２の縁部に沿って設けられている。立設壁部３１は、上方被覆部２２の縁部の幅方向Ｙの一端から他端までの略全体に亘って形成されている。平面視において、固定壁部２４と立設壁部３１とは、略直角をなすように互いに繋がっている。すなわち、立設壁部３１は、上方被覆部２２における奥行方向Ｘの一端部に繋がっており、立設壁部３１と固定壁部２４とが繋がる部位は角部３２をなしている。コネクタホルダ１１は、上方被覆部２２の上面において角部３２が最も低くなる傾斜姿勢で車体に固定される。 (Standing wall 31)
As shown in FIGS. 3 and 4, an upright wall portion 31 is erected on the upper surface of the upper covering portion 22 in addition to the fixed wall portion 24. The upright wall portion 31 is provided along the edge portion of the upper covering portion 22 intersecting the edge portion 22a on which the fixed wall portion 24 is formed. The erection wall portion 31 is formed over substantially the entire width direction Y from one end to the other end of the edge portion of the upper covering portion 22. In a plan view, the fixed wall portion 24 and the standing wall portion 31 are connected to each other so as to form a substantially right angle. That is, the erection wall portion 31 is connected to one end of the upper covering portion 22 in the depth direction X, and the portion where the erection wall portion 31 and the fixed wall portion 24 are connected forms a corner portion 32. The connector holder 11 is fixed to the vehicle body in an inclined posture in which the corner portion 32 is the lowest on the upper surface of the upper covering portion 22.

図２及び図４に示すように、立設壁部３１の幅方向Ｙの一端部は、幅方向Ｙに沿って固定壁部２４の裏面側に延出する延出部３３を有している。延出部３３は、固定壁部２４の裏面から幅方向Ｙに延出している。 As shown in FIGS. 2 and 4, one end of the erection wall portion 31 in the width direction Y has an extension portion 33 extending toward the back surface side of the fixed wall portion 24 along the width direction Y. ..
