Description

電子制御装置electronic control unit
　本発明は、電子制御装置に関する。 The present invention relates to an electronic control device.
　近年、自動運転システム又は先進運転支援システムのための電子制御装置が車両に搭載されている。この種の電子制御装置を車両に搭載する場所は、被水の恐れがほとんどない車室内から、降雨時の影響を多大に受けるエンジンルーム内まで様々である。降雨時に被水するエンジンルーム内に搭載される電子制御装置には、完全なシールド構造（防水構造）が求められる。これに対して、たとえば、車両のコンソールボックス内に搭載される電子制御装置では、エアコン等から垂れ落ちる水滴など、限られた水滴に対応すればよいため、部品コストや材料コストを抑えるために簡易なシールド構造が求められる。 In recent years, electronic control devices for automatic driving systems or advanced driving support systems have been installed in vehicles. This type of electronic control device can be installed in a variety of locations in a vehicle, from the interior of the vehicle, where there is little risk of exposure to water, to the interior of the engine room, which is greatly affected by rain. Electronic control units installed in the engine compartment, which is exposed to water during rain, must have a completely shielded structure (waterproof structure). On the other hand, for example, an electronic control unit installed in a vehicle's console box only needs to handle a limited number of water droplets, such as those dripping from an air conditioner. A shield structure is required.

　図１～図３に示すように、電子制御装置１０は、回路基板１１（図３）と、この回路基板１１を収容する筐体１２と、を備えている。電子制御装置１０は、例えば、自動運転システム用又は先進運転支援システム用として、自動車などの車両に搭載される。 As shown in FIGS. 1 to 3, the electronic control device 10 includes a circuit board 11 (FIG. 3) and a housing 12 that houses the circuit board 11. The electronic control device 10 is mounted on a vehicle such as an automobile, for example, for an automatic driving system or an advanced driving support system.
　回路基板１１は、例えばガラスエポキシを基材とするプリント配線基板によって構成される。回路基板１１は、電子制御装置１０の上方から見て略長方形に形成されている。回路基板１１には、電子部品１５（図３）及びコネクタ１６（１６ａ～１６ｄ）が搭載されている。電子部品１５は、例えば、ＬＳＩ素子である。ＬＳＩは、Large Scale Integrationの略称である。 The circuit board 11 is composed of a printed wiring board made of glass epoxy as a base material, for example. The circuit board 11 is formed into a substantially rectangular shape when viewed from above the electronic control device 10 . On the circuit board 11, electronic components 15 (FIG. 3) and connectors 16 (16a to 16d) are mounted. The electronic component 15 is, for example, an LSI element. LSI is an abbreviation for Large Scale Integration.
　電子部品１５は、回路基板１１の回路エリアに搭載されている。回路エリアには配線パターンが形成され、この配線パターンに電気的に接続する状態で電子部品１５が搭載されている。なお、回路基板１１の回路エリアには、電子部品１５以外のＬＳＩ素子や、ＬＳＩ素子以外の電子部品も搭載されるが、図３ではそれらの電子部品を省略している。電子部品は、回路基板１１の片面のみに搭載されていてもよいし、回路基板１１の両面に搭載されていてもよい。 The electronic component 15 is mounted on the circuit area of the circuit board 11. A wiring pattern is formed in the circuit area, and electronic components 15 are mounted to be electrically connected to this wiring pattern. Note that although LSI elements other than the electronic component 15 and electronic components other than the LSI element are also mounted in the circuit area of the circuit board 11, these electronic components are omitted in FIG. The electronic components may be mounted on only one side of the circuit board 11, or may be mounted on both sides of the circuit board 11.
　回路基板１１の端部には、複数のコネクタ１６が搭載されている。複数のコネクタ１６は、回路基板１１の一部の領域であって、回路基板１１の端部に確保されたコネクタ搭載領域１４に搭載されている。回路基板１１に搭載されるコネクタ１６の個数は、必要に応じて変更可能である。本実施形態においては、一例として、４つのコネクタ１６が回路基板１１に搭載されている。４つのコネクタ１６は、回路基板１１の端辺に沿って配列されている。各々のコネクタ１６のサイズは、コネクタピンの数などによって決まる。 A plurality of connectors 16 are mounted on the end of the circuit board 11. The plurality of connectors 16 are mounted in a connector mounting area 14 that is a part of the circuit board 11 and is secured at an end of the circuit board 11. The number of connectors 16 mounted on the circuit board 11 can be changed as necessary. In this embodiment, as an example, four connectors 16 are mounted on the circuit board 11. The four connectors 16 are arranged along the edge of the circuit board 11. The size of each connector 16 is determined by the number of connector pins, etc.
　本明細書においては、説明の便宜上、４つのコネクタ１６にそれぞれ異なる符号１６ａ，１６ｂ，１６ｃ，１６ｄを付すことにより、各々のコネクタ１６を区別する。コネクタ配列方向で隣り合う２つのコネクタ１６（例えば、コネクタ１６ｂとコネクタ１６ｃ）の間には、それぞれ適度な間隔があけられている。コネクタ配列方向は、図１及び図５に示すＸ方向と平行な方向である。図３の奥行き方向（言い換えると、図２の左右方向）におけるコネクタ搭載領域１４の寸法は、コネクタ１６ａの搭載位置からコネクタ１６ｄの搭載位置までの寸法と同等か、それよりも少し大きい。 In this specification, for convenience of explanation, each of the four connectors 16 is distinguished by being given different symbols 16a, 16b, 16c, and 16d. An appropriate interval is provided between two adjacent connectors 16 (for example, connector 16b and connector 16c) in the connector arrangement direction. The connector arrangement direction is a direction parallel to the X direction shown in FIGS. 1 and 5. The dimension of the connector mounting area 14 in the depth direction of FIG. 3 (in other words, the left-right direction of FIG. 2) is equal to or slightly larger than the dimension from the mounting position of the connector 16a to the mounting position of the connector 16d.
　筐体１２は、高さ寸法（厚み寸法）が小さく抑えられた扁平の略直方体形状に形成されている。筐体１２は、複数のコネクタ開口部２０を有している。１つのコネクタ開口部２０には、１つのコネクタ１６が配置されている。つまり、コネクタ開口部２０は、コネクタ１６の個数分だけ設けられている。コネクタ開口部２０では、コネクタ１６と雄雌の関係にあるケーブル側コネクタ（図示せず）をコネクタ１６に接続できるように、コネクタ１６が外部に露出する状態で配置される。 The housing 12 is formed into a flat, substantially rectangular parallelepiped shape with a small height (thickness). The housing 12 has a plurality of connector openings 20. One connector 16 is arranged in one connector opening 20 . In other words, the number of connector openings 20 is equal to the number of connectors 16. In the connector opening 20, the connector 16 is arranged to be exposed to the outside so that a cable-side connector (not shown) having a male-female relationship with the connector 16 can be connected to the connector 16.
　筐体１２は、上側筐体としての筐体ベース２１と、下側筐体としての筐体カバー２２とによって構成されている。電子制御装置１０は、筐体ベース２１を上側、筐体カバー２２を下側にして、車両に搭載される。また、電子制御装置１０は、回路基板１１及びコネクタ１６が水平になるか、あるいは、コネクタ１６が水平よりも下向きになるように車両に搭載される。 The casing 12 includes a casing base 21 as an upper casing and a casing cover 22 as a lower casing. The electronic control device 10 is mounted on a vehicle with the housing base 21 facing upward and the housing cover 22 facing downward. Further, the electronic control device 10 is mounted on the vehicle so that the circuit board 11 and the connector 16 are horizontal, or the connector 16 is directed downward from the horizontal.
　筐体ベース２１及び筐体カバー２２は、例えば、ネジ止めによって相互に固定される。筐体１２の内部には、筐体ベース２１と筐体カバー２２とを組み合わせることで基板収容空間１３が形成され、この基板収容空間１３に回路基板１１が収容される。筐体ベース２１及び筐体カバー２２は、好ましくは、金属材料によって構成される。筐体１２を金属材料によって構成した場合は、電磁波ノイズをシールドする機能を筐体１２に持たせることができる。 The housing base 21 and the housing cover 22 are fixed to each other by, for example, screws. A board accommodating space 13 is formed inside the casing 12 by combining the casing base 21 and the casing cover 22, and the circuit board 11 is accommodated in this board accommodating space 13. The housing base 21 and the housing cover 22 are preferably made of metal material. When the housing 12 is made of a metal material, the housing 12 can have a function of shielding electromagnetic noise.
　筐体ベース２１は、例えば、アルミダイキャスト法によって得られる部材である。筐体ベース２１は、コネクタ１６（１６ａ～１６ｄ）が格納されるコネクタ格納部２３と、回路基板１１が格納される基板格納部２４と、を一体に備えている。コネクタ格納部２３は、コネクタ１６を上方から覆っている。基板格納部２４は、コネクタ搭載領域１４を除いて回路基板１１を上方から覆っている。 The housing base 21 is, for example, a member obtained by aluminum die-casting. The housing base 21 integrally includes a connector storage section 23 in which the connectors 16 (16a to 16d) are stored, and a board storage section 24 in which the circuit board 11 is stored. The connector housing section 23 covers the connector 16 from above. The board storage section 24 covers the circuit board 11 from above except for the connector mounting area 14.
　筐体カバー２２は、コネクタ搭載領域１４を含めて回路基板１１を下方から覆っている。筐体カバー２２は、例えば、板金加工によって得られる部材である。筐体カバー２２は、コネクタ１６側に向かって垂直に立ち上がるカバー端部２２ａを有している。カバー端部２２ａは、立ち上がり部の一例として筐体カバー２２に形成されている。 The housing cover 22 covers the circuit board 11 including the connector mounting area 14 from below. The housing cover 22 is, for example, a member obtained by sheet metal processing. The housing cover 22 has a cover end 22a that stands up vertically toward the connector 16 side. The cover end portion 22a is formed on the housing cover 22 as an example of a rising portion.
　カバー端部２２ａは、コネクタ１６が配置された位置では、コネクタ１６の下面に近接する位置まで延在している（図３参照）。また、カバー端部２２ａは、Ｘ方向で隣り合うコネクタ１６間の位置では、コネクタ１６の下面よりも上方まで延在している。 At the position where the connector 16 is placed, the cover end 22a extends to a position close to the lower surface of the connector 16 (see FIG. 3). Further, the cover end portion 22a extends above the lower surface of the connector 16 at a position between adjacent connectors 16 in the X direction.
　カバー端部２２ａは、図６に示すように、コネクタ格納部２３のコネクタ配置面２８よりも内側（基板収容空間１３の中心側）に配置されている。言い換えると、コネクタ格納部２３のコネクタ配置面２８は、カバー端部２２ａよりも外側に配置されている。また、カバー端部２２ａは、コネクタ配列方向で隣り合うコネクタ１６の間では、筐体ベース２１のコネクタ配置面２８と重なり合う状態に配置されている。 As shown in FIG. 6, the cover end portion 22a is arranged inside the connector placement surface 28 of the connector storage section 23 (on the center side of the board storage space 13). In other words, the connector placement surface 28 of the connector storage portion 23 is placed outside the cover end 22a. Further, the cover end portion 22a is arranged to overlap the connector arrangement surface 28 of the housing base 21 between the connectors 16 adjacent in the connector arrangement direction.
　さらに詳述すると、コネクタ格納部２３のコネクタ配置面２８は、筐体ベース２１の端壁部３０の外面として形成されている。端壁部３０は、端壁部３０の厚み寸法を部分的に小さくした薄肉部３０ａを有している。筐体カバー２２のカバー端部２２ａは、コネクタ配列方向で隣り合うコネクタ１６の間で、端壁部３０の薄肉部３０ａと重なり合う状態で配置されている。 To explain in more detail, the connector placement surface 28 of the connector housing section 23 is formed as the outer surface of the end wall section 30 of the housing base 21. The end wall portion 30 has a thin portion 30a in which the thickness of the end wall portion 30 is partially reduced. The cover end portion 22a of the housing cover 22 is arranged to overlap the thin wall portion 30a of the end wall portion 30 between the adjacent connectors 16 in the connector arrangement direction.
　以下に、筐体ベース２１の構成について更に詳しく説明する。
　筐体ベース２１には段差部２５が形成されている。段差部２５は、筐体１２の上面で、かつ、コネクタ格納部２３と基板格納部２４との境界に形成されている。また、段差部２５は、コネクタ格納部２３が基板格納部２４よりも上方に突出する状態で形成されている。これにより、コネクタ格納部２３の上面２６は、基板格納部２４の上面２７よりも一段高く配置されている。筐体１２の上面は、コネクタ格納部２３の上面２６と基板格納部２４の上面２７とを含む面である。 Below, the configuration of the housing base 21 will be explained in more detail.
A stepped portion 25 is formed in the housing base 21. The step portion 25 is formed on the upper surface of the housing 12 and at the boundary between the connector storage portion 23 and the board storage portion 24 . Furthermore, the stepped portion 25 is formed such that the connector storage portion 23 projects upwardly relative to the board storage portion 24 . As a result, the top surface 26 of the connector storage section 23 is arranged one step higher than the top surface 27 of the board storage section 24. The upper surface of the housing 12 is a surface that includes the upper surface 26 of the connector storage section 23 and the upper surface 27 of the board storage section 24 .
　コネクタ格納部２３は、上述した上面２６の他に、コネクタ配置面２８と、一対の側面２９（図１、図２）と、を有している。上面２６は、コネクタ配置面２８の上縁２８ａと接する面である。上面２６は、コネクタ配置面２８と直角をなす面でもある。コネクタ配置面２８には、上述したコネクタ開口部２０が形成され、このコネクタ開口部２０にコネクタ１６が配置されている。一対の側面２９は、上面２６及びコネクタ配置面２８と接する面である。側面２９は、上面２６及びコネクタ配置面２８と直角をなす面でもある。 In addition to the above-mentioned top surface 26, the connector housing section 23 has a connector placement surface 28 and a pair of side surfaces 29 (FIGS. 1 and 2). The upper surface 26 is a surface that contacts the upper edge 28a of the connector placement surface 28. The upper surface 26 is also a surface that is perpendicular to the connector placement surface 28. The connector opening 20 described above is formed in the connector placement surface 28, and the connector 16 is placed in the connector opening 20. The pair of side surfaces 29 are surfaces that are in contact with the top surface 26 and the connector placement surface 28 . The side surface 29 is also a surface that is perpendicular to the top surface 26 and the connector placement surface 28 .
　コネクタ格納部２３の上面２６には、ガイド部の一例として、ガイド縁３１，３２が形成されている。ガイド縁３１，３２の数は必要に応じて変更可能である。本実施形態においては、一例として、コネクタ格納部２３の上面２６に２つのガイド縁３１，３２が形成されている。ガイド縁３１は、筐体ベース２１を上方から見て円弧状に形成され、ガイド縁３２も同様に円弧状に形成されている。ガイド縁３１は、筐体ベース２１の幅方向（図２の左右方向）の中心位置を示す中心線上において、ガイド縁３２よりもコネクタ配置面２８の上縁２８ａに近い位置に形成されている。筐体ベース２１の幅方向の中心位置を示す中心線は、図２に示すＩＩＩ－ＩＩＩ線とほぼ同じ位置に存在する仮想線である。 Guide edges 31 and 32 are formed on the upper surface 26 of the connector storage section 23 as an example of a guide section. The number of guide edges 31, 32 can be changed as necessary. In this embodiment, as an example, two guide edges 31 and 32 are formed on the upper surface 26 of the connector storage section 23. The guide edge 31 is formed in an arc shape when the housing base 21 is viewed from above, and the guide edge 32 is similarly formed in an arc shape. The guide edge 31 is formed at a position closer to the upper edge 28a of the connector arrangement surface 28 than the guide edge 32 is on the center line indicating the center position of the housing base 21 in the width direction (left-right direction in FIG. 2). The center line indicating the center position of the housing base 21 in the width direction is an imaginary line located at approximately the same position as the line III-III shown in FIG.
　コネクタ格納部２３の上面２６は、ガイド縁３１，３２によって３つの面２６ａ，２６ｂ，２６ｃに区分されている。
　ここで、図２のＩＩＩ－ＩＩＩ線上における３つの面２６ａ，２６ｂ，２６ｃの位置関係について説明する。
　面２６ａは、面２６ｂよりもコネクタ配置面２８の上縁２８ａの近傍に配置されている。面２６ｂは、ガイド縁３１とガイド縁３２との間に配置されている。面２６ｃは、面２６ｂよりも段差部２５の近傍に配置されている。また、面２６ａと面２６ｂは、ガイド縁３１を境に区分され、面２６ｂと面２６ｃは、ガイド縁３２を境に区分されている。 The upper surface 26 of the connector storage section 23 is divided into three surfaces 26a, 26b, and 26c by guide edges 31 and 32.
Here, the positional relationship between the three surfaces 26a, 26b, and 26c on line III-III in FIG. 2 will be explained.
The surface 26a is located closer to the upper edge 28a of the connector placement surface 28 than the surface 26b. The surface 26b is arranged between the guide edge 31 and the guide edge 32. The surface 26c is arranged closer to the stepped portion 25 than the surface 26b. Moreover, the surface 26a and the surface 26b are divided by the guide edge 31 as a boundary, and the surface 26b and the surface 26c are divided by the guide edge 32 as a boundary.
　ガイド縁３１は、電子制御装置１０の高さ方向において、面２６ａに対して面２６ｂを僅かに凹ませた状態で形成され、ガイド縁３２は、面２６ｂに対して面２６ｃを僅かに凹ませた状態で形成されている。このため、コネクタ格納部２３の上面２６を構成する３つの面２６ａ，２６ｂ，２６ｃのうち、面２６ｂは、面２６ａよりも僅かに低い位置に配置され、面２６ｃは、面２６ｂよりも僅かに低い位置に配置されている。 The guide edge 31 is formed with the surface 26b slightly recessed relative to the surface 26a in the height direction of the electronic control device 10, and the guide edge 32 is formed with the surface 26c slightly recessed relative to the surface 26b. It is formed in a state in which Therefore, among the three surfaces 26a, 26b, and 26c that constitute the upper surface 26 of the connector storage section 23, the surface 26b is arranged at a slightly lower position than the surface 26a, and the surface 26c is slightly lower than the surface 26b. placed in a low position.
　ガイド縁３１は、主に面２６ｂに滴下した水滴などの液体をコネクタ搭載領域１４よりも外側に導くために形成されている。このため、図２の左右方向において、ガイド縁３１の一端はコネクタ１６ａの搭載位置よりも外側（図２の右側）でコネクタ配置面２８に接し、ガイド縁３１の他端はコネクタ１６ｄの搭載位置よりも外側（図２の左側）でコネクタ配置面２８に接している。ガイド縁３２は、主に面２６ｂに滴下した水滴などの液体をコネクタ搭載領域１４よりも外側に導くために形成されている。ガイド縁３２の両端は、コネクタ搭載領域１４よりも外側で一対の側面２９に接している。 The guide edge 31 is mainly formed to guide liquid such as water droplets dropped onto the surface 26b to the outside of the connector mounting area 14. Therefore, in the left-right direction in FIG. 2, one end of the guide edge 31 contacts the connector placement surface 28 on the outside (on the right side in FIG. 2) of the mounting position of the connector 16a, and the other end of the guide edge 31 contacts the mounting position of the connector 16d. It is in contact with the connector placement surface 28 on the outside (left side in FIG. 2). The guide edge 32 is formed mainly to guide liquid such as water droplets dropped onto the surface 26b to the outside of the connector mounting area 14. Both ends of the guide edge 32 are in contact with a pair of side surfaces 29 outside the connector mounting area 14.
　また、コネクタ格納部２３の上面２６には第１流路３５が形成され、コネクタ格納部２３のコネクタ配置面２８には第２流路３６が形成されている。第１流路３５は、コネクタ開口部２０の幅方向Ｘ（図１、図４）の外側に液体を導くために形成された流路であり、第２流路３６も同様の目的で形成された流路である。コネクタ開口部２０の幅方向Ｘの外側とは、コネクタ開口部２０を正面方向から見たときに、コネクタ開口部２０の両側縁よりも外側を意味する。 Furthermore, a first flow path 35 is formed on the upper surface 26 of the connector storage section 23, and a second flow path 36 is formed on the connector placement surface 28 of the connector storage section 23. The first flow path 35 is a flow path formed to guide liquid to the outside of the connector opening 20 in the width direction X (FIGS. 1 and 4), and the second flow path 36 is also formed for the same purpose. This is a flow path. The outside of the connector opening 20 in the width direction X means the outside of both side edges of the connector opening 20 when the connector opening 20 is viewed from the front.
　第１流路３５は、コネクタ格納部２３の上面２６を構成する３つの面２６ａ，２６ｂ，２６ｃのうち、コネクタ配置面２８の上縁２８ａに最も近い面２６ａに形成されている。コネクタ格納部２３の面２６ａには複数の第１流路３５が形成されている。第１流路３５は、１つのコネクタ開口部２０につき１つずつ形成されている。つまり、第１流路３５は、コネクタ１６の個数分だけ形成されている。第１流路３５は、コネクタ格納部２３の上面２６（面２６ａ）を部分的に凹ませた状態で形成されている。 The first flow path 35 is formed on the surface 26a closest to the upper edge 28a of the connector placement surface 28 among the three surfaces 26a, 26b, and 26c forming the upper surface 26 of the connector storage section 23. A plurality of first flow paths 35 are formed on the surface 26a of the connector storage section 23. One first flow path 35 is formed for each connector opening 20. In other words, the number of first flow paths 35 is equal to the number of connectors 16. The first flow path 35 is formed by partially recessing the upper surface 26 (surface 26a) of the connector storage section 23.
　第１流路３５は、第１流路３５の位置がコネクタ開口部２０の幅方向中央から左右に遠ざかるにつれて、コネクタ配置面２８の上縁２８ａから第１流路３５までの距離が小さくなるように形成されている。また、第１流路３５は、コネクタ格納部２３の上面２６を正面方向から見てＶ字形に形成されている。つまり、第１流路３５は、正面視Ｖ字形の溝になっている。コネクタ開口部２０の幅方向Ｘにおける第１流路３５の両端は、コネクタ配置面２８の上縁２８ａに接している。第１流路３５の底面は、コネクタ開口部２０の幅方向Ｘにおける第１流路３５の中央から両端に向かって徐々に低位になるテーパー面でもよいし、平らな面でもよい。 The first flow path 35 is configured such that the distance from the upper edge 28a of the connector placement surface 28 to the first flow path 35 becomes smaller as the position of the first flow path 35 moves leftward and rightward from the center of the connector opening 20 in the width direction. is formed. Further, the first flow path 35 is formed in a V-shape when viewing the top surface 26 of the connector storage section 23 from the front direction. In other words, the first flow path 35 is a V-shaped groove when viewed from the front. Both ends of the first flow path 35 in the width direction X of the connector opening 20 are in contact with the upper edge 28a of the connector placement surface 28. The bottom surface of the first flow path 35 may be a tapered surface that gradually becomes lower from the center of the first flow path 35 toward both ends in the width direction X of the connector opening 20, or may be a flat surface.
　第２流路３６は、コネクタ配置面２８の上縁２８ａよりも下方に形成されている。また、コネクタ格納部２３のコネクタ配置面２８には複数の第２流路３６が形成されている。第２流路３６は、１つのコネクタ開口部２０につき１つずつ形成されている。つまり、第２流路３６は、コネクタ１６の個数分だけ形成されている。第２流路３６は、コネクタ格納部２３のコネクタ配置面２８から僅かに突出する状態で形成されている。 The second flow path 36 is formed below the upper edge 28a of the connector placement surface 28. Further, a plurality of second flow paths 36 are formed in the connector placement surface 28 of the connector storage section 23. One second flow path 36 is formed for each connector opening 20. In other words, the number of second flow paths 36 is equal to the number of connectors 16. The second flow path 36 is formed to slightly protrude from the connector placement surface 28 of the connector housing section 23 .
　第２流路３６は、第２流路３６の位置がコネクタ開口部２０の幅方向中央から遠ざかるにつれて、コネクタ開口部２０の上縁２０ａから第２流路３６までの距離が小さくなるように形成されている。また、第２流路３６は、コネクタ格納部２３のコネクタ配置面２８を正面方向から見て三角屋根形状に形成されている。 The second flow path 36 is formed such that the distance from the upper edge 20a of the connector opening 20 to the second flow path 36 becomes smaller as the position of the second flow path 36 moves away from the widthwise center of the connector opening 20. has been done. Further, the second flow path 36 is formed in a triangular roof shape when the connector placement surface 28 of the connector storage section 23 is viewed from the front direction.
　コネクタ開口部２０の幅方向Ｘにおける第２流路３６の両端には排液路３７が接続されている。排液路３７は、第１流路３５や第２流路３６によって導かれた液体をコネクタ開口部２０の下方へと排出させるための流路である。排液路３７は、第２流路３６と共にコネクタ配置面２８に形成されている。排液路３７は、第２流路３６と同様に、コネクタ格納部２３のコネクタ配置面２８から僅かに突出する状態で形成されている。排液路３７は、コネクタ開口部２０の両側に形成されている。コネクタ開口部２０の幅方向Ｘにおいて、コネクタ開口部２０の側縁から排液路３７までの距離は、排液路３７の位置がコネクタ配置面２８の上縁２８ａから遠ざかるにつれて大きくなっている。このため、第１流路３５や第２流路３６によって排液路３７に導かれた液体は、コネクタ開口部２０の側縁から徐々に遠ざかりながら下方に流れる。 A drainage path 37 is connected to both ends of the second flow path 36 in the width direction X of the connector opening 20. The liquid drain path 37 is a flow path for discharging the liquid guided by the first flow path 35 and the second flow path 36 below the connector opening 20 . The drain path 37 and the second flow path 36 are formed on the connector placement surface 28 . Similarly to the second flow path 36, the drain path 37 is formed to slightly protrude from the connector placement surface 28 of the connector storage section 23. Drain passages 37 are formed on both sides of connector opening 20 . In the width direction X of the connector opening 20, the distance from the side edge of the connector opening 20 to the drain path 37 increases as the position of the drain path 37 moves away from the upper edge 28a of the connector placement surface 28. Therefore, the liquid guided to the drain path 37 by the first flow path 35 and the second flow path 36 flows downward while gradually moving away from the side edge of the connector opening 20.
　続いて、本実施形態に係る電子制御装置１０の作用及び効果について説明する。
　本実施形態においては、一例として、電子制御装置１０を水平な姿勢で自動車のコンソールボックス内に搭載した場合を想定する。また、本実施形態においては、基板格納部２４の上面２７に液体が滴下した場合と、コネクタ格納部２３の上面２６に液体が滴下した場合を想定する。なお、電子制御装置１０の筐体１２に液体が滴下する具体的なケースとしては、例えば、コンソールボックス上で飲料用容器からこぼれた飲み物がコンソールボックスの隙間を通して筐体１２に垂れ落ちるケース、あるいは、コンソールボックスを通して後部座席に空調空気を送るエアコンダクトの表面に生じた結露水（水滴）が筐体１２に垂れ落ちるケースなどが考えられる。 Next, the functions and effects of the electronic control device 10 according to this embodiment will be explained.
In this embodiment, as an example, it is assumed that the electronic control device 10 is mounted in a console box of an automobile in a horizontal position. Further, in this embodiment, a case is assumed in which a liquid is dropped on the upper surface 27 of the board storage section 24 and a case in which a liquid is dropped on the upper surface 26 of the connector storage section 23. Specific cases in which liquid drips onto the housing 12 of the electronic control device 10 include, for example, a case where a drink spilled from a beverage container on the console box drips onto the housing 12 through a gap in the console box; A possible case is that condensed water (water droplets) formed on the surface of an air conditioner duct that sends conditioned air to the rear seats through a console box drips onto the housing 12.
　まず、基板格納部２４の上面２７に滴下した液体は、自動車の走行中に生じる振動や加減速などにより、コネクタ配置面２８の上縁２８ａに近づく方向に移動する場合がある。この場合、液体は、段差部２５に達すると、段差部２５によってコネクタ格納部２３の両側に導かれる。こうして導かれた液体は、筐体ベース２１の側面を伝って流れ落ちる。したがって、基板格納部２４の上面２７に滴下した液体がコネクタ開口部２０に達することを段差部２５によって抑制することができる。 First, the liquid dripped onto the upper surface 27 of the board storage section 24 may move toward the upper edge 28a of the connector placement surface 28 due to vibrations, acceleration and deceleration, etc. that occur while the vehicle is running. In this case, when the liquid reaches the stepped portion 25, it is guided to both sides of the connector storage portion 23 by the stepped portion 25. The liquid thus led flows down along the side surface of the housing base 21. Therefore, the stepped portion 25 can prevent the liquid dripping onto the upper surface 27 of the board storage portion 24 from reaching the connector opening 20 .
　一方、コネクタ格納部２３の上面２６に滴下した液体については、３つの面２６ａ，２６ｂ，２６ｃのうち、いずれの面に滴下するかによって、液体の流れ方が変わる。以下、具体的に説明する。 On the other hand, regarding the liquid dropped onto the upper surface 26 of the connector storage section 23, the way the liquid flows changes depending on which of the three surfaces 26a, 26b, and 26c the liquid is dropped on. This will be explained in detail below.
　まず、面２６ｃに滴下した液体は、自動車の走行中に生じる振動や加減速などにより、コネクタ配置面２８の上縁２８ａに近づく方向に移動する場合がある。この場合、液体は、ガイド縁３２に達すると、図１及び図５に矢印で示すように、ガイド縁３２に沿ってコネクタ格納部２３の側面２９へと導かれる。こうして導かれた液体は、コネクタ格納部２３の側面２９を伝って流れ落ちる。したがって、面２６ｃに滴下した液体がコネクタ開口部２０に達することをガイド縁３２によって抑制することができる。 First, the liquid dropped onto the surface 26c may move toward the upper edge 28a of the connector placement surface 28 due to vibrations, acceleration and deceleration, etc. that occur while the vehicle is running. In this case, when the liquid reaches the guide edge 32, it is guided along the guide edge 32 to the side surface 29 of the connector housing 23, as indicated by the arrows in FIGS. 1 and 5. The liquid guided in this way flows down along the side surface 29 of the connector storage section 23. Therefore, the guide edge 32 can prevent the liquid dripping onto the surface 26c from reaching the connector opening 20.
　また、面２６ｂに滴下した液体は、自動車の走行中に生じる振動や加減速などにより、コネクタ配置面２８の上縁２８ａに近づく方向に移動する場合がある。この場合、液体は、ガイド縁３１に達すると、図１及び図５に矢印で示すように、ガイド縁３１に沿ってコネクタ格納部２３の側面２９へと導かれる。こうして導かれた液体は、コネクタ格納部２３の側面２９に沿って流れ落ちる。したがって、面２６ｂに滴下した液体がコネクタ開口部２０に達することをガイド縁３１によって抑制することができる。 Additionally, the liquid dropped on the surface 26b may move in a direction toward the upper edge 28a of the connector placement surface 28 due to vibrations, acceleration and deceleration, etc. that occur while the vehicle is running. In this case, when the liquid reaches the guide edge 31, it is guided along the guide edge 31 to the side surface 29 of the connector housing 23, as indicated by the arrows in FIGS. 1 and 5. The liquid thus led flows down along the side surface 29 of the connector storage section 23. Therefore, the guide edge 31 can prevent the liquid dripping onto the surface 26b from reaching the connector opening 20.
　一方、面２６ａに滴下する液体は、第１流路３５よりもガイド縁３１に近い位置に滴下するか、あるいは第１流路３５よりもコネクタ配置面２８の上縁２８ａに近い位置に滴下するかによって、流れる流路が変わる。
　まず、第１流路３５よりもガイド縁３１に近い位置で面２６ａに滴下した液体は、自動車の走行中に生じる振動や加減速などにより、コネクタ配置面２８の上縁２８ａに近づく方向に移動する場合がある。この場合、液体は、いずれかの第１流路３５に達すると、第１流路３５に流れ込み、図７に矢印で示すように第１流路３５に案内されてコネクタ開口部２０の幅方向Ｘの外側に導かれる。こうして導かれた液体は、第１流路３５の両端からコネクタ配置面２８を伝って流れ落ちた後、排液路３７に案内されて流れ落ちる。したがって、第１流路３５よりもガイド縁３１に近い位置で面２６ａに滴下した液体がコネクタ開口部２０に達することを第１流路３５によって抑制することができる。 On the other hand, the liquid dripping onto the surface 26a is dripped at a position closer to the guide edge 31 than the first flow path 35, or at a position closer to the upper edge 28a of the connector arrangement surface 28 than the first flow path 35. The flow path changes depending on the flow.
First, the liquid dropped onto the surface 26a at a position closer to the guide edge 31 than the first flow path 35 moves toward the upper edge 28a of the connector placement surface 28 due to vibrations, acceleration and deceleration, etc. that occur while the vehicle is running. There are cases where In this case, when the liquid reaches any of the first flow paths 35, it flows into the first flow path 35, and is guided along the first flow path 35 in the width direction of the connector opening 20 as shown by the arrow in FIG. Guided outside of X. The liquid thus led flows down from both ends of the first flow path 35 along the connector placement surface 28, and then is guided to the drain path 37 and flows down. Therefore, the first flow path 35 can prevent the liquid dripping onto the surface 26a at a position closer to the guide edge 31 than the first flow path 35 from reaching the connector opening 20.
　これに対して、第１流路３５よりもコネクタ配置面２８の上縁２８ａに近い位置で面２６ａに滴下した液体は、自動車の走行中に生じる振動や加減速などにより、コネクタ配置面２８の上縁２８ａに近づく方向に移動する場合がある。この場合、液体は、コネクタ配置面２８の上縁２８ａまで移動すると、図７に矢印で示すようにコネクタ配置面２８を伝って流れ落ちることにより、第２流路３６に達する。第２流路３６に達した液体は、図７に矢印で示すように第２流路３６に案内されてコネクタ開口部２０の幅方向Ｘの外側に導かれる。こうして導かれた液体は、第２流路３６の両端部から排液路３７に案内されて流れ落ちる。したがって、第１流路３５よりもコネクタ配置面２８の上縁２８ａに近い位置で面２６ａに滴下した液体がコネクタ開口部２０に達することを第２流路３６によって抑制することができる。 On the other hand, the liquid dropped onto the surface 26a at a position closer to the upper edge 28a of the connector arrangement surface 28 than the first flow path 35 is caused by vibrations, acceleration and deceleration, etc. occurring while the automobile is running. It may move in a direction approaching the upper edge 28a. In this case, when the liquid moves to the upper edge 28a of the connector placement surface 28, it flows down the connector placement surface 28 as shown by the arrow in FIG. 7, thereby reaching the second flow path 36. The liquid that has reached the second flow path 36 is guided into the second flow path 36 and led to the outside of the connector opening 20 in the width direction X, as shown by the arrow in FIG. The liquid thus led is guided from both ends of the second flow path 36 to the drain path 37 and flows down. Therefore, the second flow path 36 can prevent the liquid dripping onto the surface 26 a from reaching the connector opening 20 at a position closer to the upper edge 28 a of the connector arrangement surface 28 than the first flow path 35 .
　また、コネクタ配列方向で隣り合うコネクタ１６の間では、図６に矢印で示すように、筐体カバー２２のカバー端部２２ａよりも外側に配置された筐体ベース２１のコネクタ配置面２８を伝って液体が流れ落ちる。このため、基板収容空間１３に液体が浸入することを抑制することができる。なお、コネクタ配置面２８を伝って流れ落ちる液体には、第１流路３５や第２流路３６に案内されて流れる液体が含まれる。 Furthermore, between the connectors 16 adjacent in the connector arrangement direction, as shown by arrows in FIG. The liquid will drip down. Therefore, it is possible to suppress liquid from entering the substrate accommodation space 13. Note that the liquid that flows down along the connector placement surface 28 includes liquid that is guided to the first flow path 35 and the second flow path 36 and flows.
　本実施形態に係る電子制御装置１０によれば、筐体１２の段差部２５よりもコネクタ配置面２８の上縁２８ａに近い位置（言い換えると、コネクタ格納部２３の上面２６）に滴下した水滴がコネクタ開口部２０に至ることを抑制することができる。 According to the electronic control device 10 according to the present embodiment, water droplets dropped at a position closer to the upper edge 28a of the connector placement surface 28 than the stepped portion 25 of the housing 12 (in other words, the upper surface 26 of the connector storage section 23) It can be suppressed from reaching the connector opening 20.
