Description

本発明は、電子部品を収容する筐体に設けられた貫通孔を通気可能に覆う通気栓を備える電子制御装置に関する。   The present invention relates to an electronic control device including a vent plug that covers a through-hole provided in a housing that houses an electronic component so as to allow ventilation.

例えば、車両に搭載されるパワーコントロールユニット（ＰＣＵ）やエンジンコントロールユニット（ＥＣＵ）等の電子制御装置は、防水が図られた筐体の内部空間に、温度上昇を伴う電子部品を実装した回路基板等が収容されて構成される。   For example, an electronic control device such as a power control unit (PCU) or an engine control unit (ECU) mounted on a vehicle is a circuit board in which electronic components with a rise in temperature are mounted in the interior space of a waterproof casing. Etc. are accommodated.

このような電子制御装置では、筐体に高い防水性が求められるが、防水性を高めるべく筐体の内部空間を密閉状態とすると、電子部品等の温度変化に応じて内部空間に圧力変化が生じ易くなり、ひいては、筐体に過大な応力が発生してしまう懸念がある。内部空間内の気体が温度変化に伴って膨張又は収縮するからである。   In such an electronic control device, the casing is required to have high waterproofness. However, if the internal space of the casing is hermetically sealed in order to improve waterproofness, pressure changes in the internal space according to temperature changes of electronic components and the like. This is likely to occur, and as a result, there is a concern that excessive stress is generated in the housing. This is because the gas in the internal space expands or contracts as the temperature changes.

そこで、例えば、特許文献１に示すように、筐体の内外の気圧差を調整するための、いわゆる呼吸フィルタ機能を備えた電子制御装置が検討されている。具体的には、この電子制御装置では、内部空間を外部に連通する通気孔を筐体に設けるとともに、該通気孔を、気体の通過を許容し且つ液体の通過を阻止する撥水性の機能性繊維材からなる呼吸フィルタで覆っている。   Therefore, for example, as shown in Patent Document 1, an electronic control device having a so-called breathing filter function for adjusting a pressure difference between the inside and outside of a housing has been studied. Specifically, in this electronic control device, a water-repellent function that allows a gas to pass and prevents a liquid from passing through is provided in the housing with a vent that communicates the internal space with the outside. It is covered with a breathing filter made of fiber material.

特開２００７−１４１９５９号公報JP 2007-141959 A

ところで、この種の電子制御装置では、筐体の内部空間の湿度が上昇することを回避することが好ましい。内部空間に収容された電子部品におけるバスバー端子等の金属部が腐食することを抑制するためである。しかしながら、気体の通過を許容する上記の呼吸フィルタでは、水蒸気の通過を阻止することが困難であるため、筐体の外部から通気孔を介して侵入する水蒸気によって内部空間の湿度が上昇してしまう懸念がある。   By the way, in this type of electronic control device, it is preferable to avoid an increase in the humidity of the internal space of the housing. This is to prevent corrosion of metal parts such as bus bar terminals in the electronic components housed in the internal space. However, in the above breathing filter that allows the passage of gas, it is difficult to prevent the passage of water vapor, and therefore the humidity of the internal space increases due to water vapor that enters from the outside of the housing through the vent hole. There are concerns.

本発明は、上記した問題を解決するためになされたもので、防水性を高めた筐体の内部空間と外部との気圧差を良好に調整できるとともに、該内部空間の湿度上昇を長期的に抑制できる電子制御装置を提供することを目的とする。   The present invention has been made to solve the above-described problems, and can satisfactorily adjust the pressure difference between the interior space of the housing with improved waterproofness and the outside, and increase the humidity in the interior space over the long term. An object of the present invention is to provide an electronic control device that can be suppressed.

前記の目的を達成するために、本発明は、内部空間に電子部品を収容するとともに、前記内部空間を外部に連通する貫通孔が形成された筐体と、前記貫通孔を通気可能に覆う通気栓とを備える電子制御装置であって、前記通気栓は、前記貫通孔に固定され且つ該貫通孔を介して前記内部空間を前記外部に連通する通気孔が設けられたボディと、前記ボディに対して、前記通気孔の前記外部側に設けられるキャップと、前記ボディと前記キャップとの間に配設されるフィルタ部材と、を有し、前記フィルタ部材は、前記通気孔の全体を覆い且つ気体の通過を許容し液体の通過を阻止する撥水フィルタと、前記撥水フィルタで被覆された状態で、前記通気孔の少なくとも一部を覆うように配設され、水分を吸放湿する調湿材と、前記撥水フィルタ及び前記調湿材を支持する支持部材と、を有することを特徴とする。   In order to achieve the above object, the present invention provides a housing in which an electronic component is accommodated in an internal space and a through hole that communicates the internal space with the outside is formed, and ventilation that covers the through hole so as to allow ventilation. An electronic control device comprising a plug, wherein the vent plug is fixed to the through-hole and is provided with a vent hole that communicates the internal space with the outside through the through-hole. On the other hand, a cap provided on the outer side of the vent hole, and a filter member disposed between the body and the cap, the filter member covers the entire vent hole and A water repellent filter that allows gas to pass and prevents liquid from passing through, and is arranged to cover at least a part of the vent hole in a state covered with the water repellent filter, and absorbs and releases moisture. Wet material and the water repellent filter A support member for supporting the fine said timing Shimezai, characterized by having a.

本発明に係る電子制御装置は、貫通孔が形成された筐体と、該貫通孔を通気可能に覆う通気栓とを備えることで、電子部品を収容する内部空間の通気性を高めることができる。このため、電子部品の温度上昇等に伴い、筐体の内部空間に温度変化が生じても、該内部空間内の気圧が過度に変化することを抑制でき、これによって、筐体等に過大な応力が発生することを回避できる。   The electronic control device according to the present invention includes a housing in which a through hole is formed and a vent plug that covers the through hole so as to allow ventilation, thereby improving the air permeability of the internal space that houses the electronic component. . For this reason, even if a temperature change occurs in the internal space of the housing due to a rise in temperature of the electronic component, etc., it is possible to suppress the air pressure in the internal space from changing excessively. The generation of stress can be avoided.

また、通気栓のボディに設けられた通気孔は、フィルタ部材を構成する撥水フィルタに覆われているため、筐体の外部から通気孔を介して内部空間に液体の水等が侵入することを回避できる。したがって、上記のようにして内部空間の通気性を高めても、該内部空間の防水性が低下することを回避できる。   Further, since the vent hole provided in the body of the vent plug is covered with the water repellent filter constituting the filter member, liquid water or the like can enter the internal space from the outside of the housing via the vent hole. Can be avoided. Therefore, even if the air permeability of the internal space is increased as described above, it is possible to avoid a decrease in the waterproof property of the internal space.

さらに、通気孔の少なくとも一部は、撥水フィルタに加えて、調湿材によっても覆われている。このため、筐体の外部から通気孔を介して内部空間に気体が流入する際、該気体に含まれる水蒸気等を調湿材によって吸収することができる。これによって、内部空間に水蒸気が侵入することを抑制できるため、該内部空間の湿度が上昇することを抑制できる。   Furthermore, at least a part of the vent hole is covered with a humidity control material in addition to the water repellent filter. For this reason, when gas flows into the internal space from the outside of the housing via the vent hole, water vapor or the like contained in the gas can be absorbed by the humidity control material. Thereby, since it is possible to suppress water vapor from entering the internal space, it is possible to suppress an increase in the humidity of the internal space.

一方、電子部品の温度上昇等に伴って筐体の内部空間の温度が上昇すると、比較的高温となった気体が、該内部空間から通気孔及び調湿材を通過して外部へと排出される。この際、調湿材に吸収されていた水分も外部へ放出されるため、該調湿材を再び水蒸気を良好に吸収することが可能な状態にすること、つまり、調湿材の吸湿能力を再生することができる。したがって、この通気栓は、長期間にわたって良好に内部空間の湿度が上昇することを抑制できる。   On the other hand, when the temperature of the internal space of the housing rises due to a rise in the temperature of the electronic components, the relatively high temperature gas is discharged from the internal space to the outside through the vent hole and the humidity control material. The At this time, the moisture absorbed in the humidity control material is also released to the outside, so that the humidity control material is made to be able to absorb water vapor well again, that is, the moisture absorption capacity of the humidity control material is increased. Can be played. Therefore, this vent plug can suppress the humidity of the internal space from rising well over a long period of time.

以上から、この電子制御装置によれば、防水性を高めた筐体の内部空間と外部との気圧差を良好に調整できるとともに、該内部空間の湿度上昇を長期的に抑制できる。その結果、電子部品におけるバスバー端子等の金属部に腐食が生じることを回避して、電子制御装置の耐久性を向上させることや長寿命化を図ることが可能になる。   As described above, according to this electronic control device, it is possible to satisfactorily adjust the pressure difference between the interior space of the housing with improved waterproofness and the outside, and to suppress the increase in humidity in the interior space over a long period of time. As a result, it is possible to avoid the occurrence of corrosion in metal parts such as bus bar terminals in the electronic component, thereby improving the durability of the electronic control device and extending the life.

上記の電子制御装置において、前記調湿材には、前記撥水フィルタを介して前記通気孔と前記外部とを連通する切欠部が設けられることが好ましい。この場合、たとえ、経年劣化等により調湿材の通気性が低下した場合であっても、調湿材の切欠部を介して気体を良好に流通させることができる。したがって、筐体の内部空間の通気性を長期的に維持することができ、電子制御装置の一層の長寿命化を図ることが可能になる。   In the above electronic control device, it is preferable that the humidity control material is provided with a cutout portion that communicates the vent hole with the outside through the water repellent filter. In this case, even if the air permeability of the humidity control material is reduced due to deterioration over time or the like, the gas can be circulated favorably through the cutout portion of the humidity control material. Therefore, the air permeability of the internal space of the housing can be maintained for a long time, and the life of the electronic control device can be further extended.

上記の電子制御装置において、前記支持部材は、枠組みから構成されることが好ましい。この場合、フィルタ部材の重量中、支持部材が占める重量を低減して、フィルタ部材の軽量化を図ることができる。また、支持部材によって覆われる面積を低減しつつ撥水フィルタ及び調湿材を支持できるため、フィルタ部材の通気性が低下することを抑制できる。   In the above electronic control device, it is preferable that the support member is constituted by a frame. In this case, the weight of the filter member can be reduced by reducing the weight occupied by the support member in the weight of the filter member. Moreover, since it can support a water-repellent filter and a humidity control material, reducing the area covered with a support member, it can suppress that the air permeability of a filter member falls.

本発明に係る電子制御装置は、通気栓の通気孔が撥水フィルタで覆われることにより、電子部品を収容する内部空間の防水性を維持しつつ、通気性を高めることができる。また、通気栓の通気孔の少なくとも一部が調湿材でさらに覆われることにより、筐体の外部から内部空間に水蒸気が侵入することを抑制できる。さらに、筐体の内部空間の気体が調湿材を通過して外部へ排出される際に、該調湿材の吸湿能力を再生することができる。   In the electronic control device according to the present invention, the vent hole of the vent plug is covered with the water repellent filter, so that the air permeability can be improved while maintaining the waterproof property of the internal space for accommodating the electronic component. In addition, when at least a part of the vent hole of the vent plug is further covered with the humidity control material, it is possible to prevent water vapor from entering the internal space from the outside of the housing. Furthermore, when the gas in the internal space of the housing passes through the humidity control material and is discharged to the outside, the moisture absorption capability of the humidity control material can be regenerated.

その結果、筐体等に過大な応力が発生することや、電子部品の金属部に腐食が生じること等を長期的に回避でき、これらによって、電子制御装置の耐久性を向上させることや長寿命化を図ることが可能になる。   As a result, it is possible to avoid the occurrence of excessive stress on the housing, etc., and the occurrence of corrosion on the metal part of the electronic component over the long term, thereby improving the durability of the electronic control device and extending the service life. It becomes possible to plan.

以下、本発明に係る電子制御装置について好適な実施形態を挙げ、添付の図面を参照しながら説明する。   DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of an electronic control device according to the invention will be described with reference to the accompanying drawings.

本発明に係る電子制御装置は、例えば、車両等に搭載されるパワーコントロールユニット（ＰＣＵ）やエンジンコントロールユニット（ＥＣＵ）のような、防水が図られた筐体と、該筐体内に収容され、温度上昇を伴う電子部品とを備えるものとして好適に適用することができる。そこで、以下では、電子制御装置が、ＰＣＵである場合を例に挙げて説明するが、特にこれに限定されるものではない。   The electronic control device according to the present invention is housed in a case that is waterproofed, such as a power control unit (PCU) or an engine control unit (ECU) mounted on a vehicle, and the like, It can be suitably applied as a device including an electronic component accompanied by a temperature rise. Therefore, in the following, a case where the electronic control device is a PCU will be described as an example, but the present invention is not particularly limited thereto.

図１に示すように、本実施形態に係る電子制御装置１０は、発電機の発電出力及びバッテリの放電出力の少なくとも一方を用いて、ハイブリッド車両走行用の交流モータを駆動するＰＣＵであり、該車両のエンジンルームに搭載される。なお、発電機、バッテリ、交流モータ、車両等の図示は省略している。   As shown in FIG. 1, an electronic control device 10 according to the present embodiment is a PCU that drives an AC motor for running a hybrid vehicle using at least one of a power generation output of a generator and a discharge output of a battery. Installed in the engine room of the vehicle. The generator, battery, AC motor, vehicle, etc. are not shown.

具体的には、電子制御装置１０は、筐体１２と、該筐体１２の内部空間に収容されるＤＣ／ＤＣコンバータ及びインバータ等から構成される電子部品（不図示）と、通気栓１６とを備えている。   Specifically, the electronic control device 10 includes a housing 12, electronic components (not shown) including a DC / DC converter and an inverter housed in the internal space of the housing 12, a vent plug 16, and the like. It has.

筐体１２は、ロアケース２０と、該ロアケース２０とボルト締結されるミドルケース２２と、該ミドルケース２２とボルト締結されるアッパーカバー２４とから構成される。ロアケース２０は、筐体１２の内部空間を外部に連通する貫通孔３０が設けられるとともに、前記発電機に接続される接続コネクタ３２及び前記交流モータに接続される接続コネクタ３４を外部に露呈させる。貫通孔３０は、通気栓１６によって通気可能に覆われる。なお、通気栓１６の詳細については後述する。   The housing 12 includes a lower case 20, a middle case 22 that is bolted to the lower case 20, and an upper cover 24 that is bolted to the middle case 22. The lower case 20 is provided with a through hole 30 that communicates the internal space of the housing 12 to the outside, and exposes the connection connector 32 connected to the generator and the connection connector 34 connected to the AC motor to the outside. The through hole 30 is covered with the vent plug 16 so as to allow ventilation. The details of the vent plug 16 will be described later.

ロアケース２０と、ミドルケース２２との間に形成される内部空間には、前記バッテリから供給される電圧を昇圧すること等が可能な前記ＤＣ／ＤＣコンバータが配設される。また、ミドルケース２２とアッパーカバー２４との間に形成される内部空間には、前記ＤＣ／ＤＣコンバータで昇圧した直流電圧を交流電圧に変換すること等が可能な前記インバータが配設される。このインバータには、スイッチング素子として、発熱量が大きいＩＧＢＴ（絶縁ゲートバイポーラトランジスタ）等が複数実装されている。   In the internal space formed between the lower case 20 and the middle case 22, the DC / DC converter capable of boosting the voltage supplied from the battery is disposed. Further, in the internal space formed between the middle case 22 and the upper cover 24, the inverter capable of converting the DC voltage boosted by the DC / DC converter into an AC voltage is disposed. In this inverter, a plurality of IGBTs (insulated gate bipolar transistors) and the like having a large heat generation are mounted as switching elements.

このため、ミドルケース２２は、前記インバータを冷却するためのウォータージャケット（不図示）等を構成する。ウォータージャケットの冷却水の流入口及び流出口は、流入用パイプ３８及び流出用パイプ４０を介して、冷却装置のポンプ等の機器類（不図示）とそれぞれ接続されている。   Therefore, the middle case 22 constitutes a water jacket (not shown) for cooling the inverter. The cooling water inlet and outlet of the water jacket are connected to devices (not shown) such as a pump of the cooling device via an inflow pipe 38 and an outflow pipe 40, respectively.

また、筐体１２の内部空間内において、上記の電子部品の各構成要素同士や、該構成要素と接続コネクタ３２、３４の各端子との間等における適宜の箇所は、例えば、銅板等の金属板を打ち抜き加工することで形成されたバスバー（不図示）により電気的に接続されている。   In addition, in the internal space of the housing 12, each of the components of the electronic component described above, or an appropriate place between the component and each terminal of the connection connectors 32 and 34, for example, is a metal such as a copper plate. They are electrically connected by a bus bar (not shown) formed by punching the plates.

図２に示すように、通気栓１６は、ロアケース２０に設けられた貫通孔３０を通気可能に覆うものであり、ボディ４２と、キャップ４４と、フィルタ部材４６とを有する。ボディ４２は、貫通孔３０の径と略等しい外径であり、内部に通気孔５６が設けられた筒状部５０と、該筒状部５０の一端側から径方向外側に向かって突出するツメ部５２と、筒状部５０の他端側から径方向外側に向かって突出するフランジ部５４とを有する。   As shown in FIG. 2, the vent plug 16 covers the through hole 30 provided in the lower case 20 so as to allow ventilation, and includes a body 42, a cap 44, and a filter member 46. The body 42 has an outer diameter substantially equal to the diameter of the through-hole 30, and has a tubular portion 50 provided with a vent hole 56 therein and a claw projecting radially outward from one end side of the tubular portion 50. And a flange portion 54 that protrudes radially outward from the other end side of the tubular portion 50.

ボディ４２の筒状部５０は、例えば、弾性変形可能な材料から形成され、その弾性力に抗して、ツメ部５２側から貫通孔３０に挿通される。これによって、貫通孔３０に対してボディ４２がスナップフィット固定される。その結果、筒状部５０の内部に設けられた通気孔５６は、貫通孔３０を介して筐体１２の内部空間を外部に連通する。   The cylindrical portion 50 of the body 42 is formed of, for example, an elastically deformable material, and is inserted into the through hole 30 from the claw portion 52 side against the elastic force. As a result, the body 42 is snap-fit to the through hole 30. As a result, the vent hole 56 provided in the cylindrical portion 50 communicates the internal space of the housing 12 to the outside through the through hole 30.

つまり、本実施形態では、通気孔５６の軸方向の一端側が筐体１２の内部空間の内側に配置され、他端側が該内部空間の外側に配置される。また、通気孔５６の軸方向の他端側（外部側）の開口５８はフランジ部５４によって囲繞される。このフランジ部５４と貫通孔３０の縁部との間にはＯリング６０が介在し、これによって、ボディ４２と貫通孔３０との間の気密性が高められている。   That is, in the present embodiment, one end side of the vent hole 56 in the axial direction is disposed inside the internal space of the housing 12 and the other end side is disposed outside the internal space. The opening 58 on the other end side (external side) in the axial direction of the vent hole 56 is surrounded by the flange portion 54. An O-ring 60 is interposed between the flange portion 54 and the edge of the through hole 30, thereby improving the airtightness between the body 42 and the through hole 30.

キャップ４４は、フランジ部５４のＯリング６０に臨む側と反対側の面から所定の間隔離間するように、該フランジ部５４に取り付けられる。このキャップ４４とフランジ部５４との間にフィルタ部材４６が配設される。この際、フィルタ部材４６とキャップ４４との間には、空気の出入りを可能とする大きさの間隙６２が形成され、且つフィルタ部材４６とフランジ部５４とは密着する。したがって、フィルタ部材４６は、キャップ４４に覆われることで保護されるとともに、間隙６２を介して通気可能に通気孔５６の外部側の開口５８を覆う。   The cap 44 is attached to the flange portion 54 so as to be separated from the surface of the flange portion 54 opposite to the side facing the O-ring 60 by a predetermined distance. A filter member 46 is disposed between the cap 44 and the flange portion 54. At this time, a gap 62 having a size allowing air to enter and exit is formed between the filter member 46 and the cap 44, and the filter member 46 and the flange portion 54 are in close contact with each other. Therefore, the filter member 46 is protected by being covered with the cap 44, and covers the opening 58 on the outside of the ventilation hole 56 so as to allow ventilation through the gap 62.

図３Ａ及び図３Ｂに示すように、フィルタ部材４６は、通気孔５６の外部側の開口５８よりも大きい外径の中空円柱形状に形成される撥水フィルタ７０と、該撥水フィルタ７０により被覆される調湿材７２と、撥水フィルタ７０及び調湿材７２を支持する支持部材７４とを有する。なお、図２及び図３Ｂでは、支持部材７４の図示を省略している。   As shown in FIGS. 3A and 3B, the filter member 46 includes a water repellent filter 70 formed in a hollow cylindrical shape having an outer diameter larger than the opening 58 on the outside of the vent hole 56, and is covered with the water repellent filter 70. And a support member 74 that supports the water repellent filter 70 and the humidity control material 72. 2 and 3B, the support member 74 is not shown.

撥水フィルタ７０は、気体の通過を許容し且つ液体の通過を阻止する材料からなり、該材料の好適な例としては、ポリテトラフルオロエチレン等が挙げられる。調湿材７２は、吸放湿性を示す材料からなり、該材料の好適な例としては、シリカゲルや、アクリル系微粒子（例えば、東洋紡製の商品名「タフチックＲ ＨＵシリーズ」）等が挙げられる。   The water repellent filter 70 is made of a material that allows passage of gas and prevents passage of liquid, and a suitable example of the material includes polytetrafluoroethylene. The humidity control material 72 is made of a material exhibiting moisture absorption / release properties. Suitable examples of the material include silica gel and acrylic fine particles (for example, “Toughtic R HU series” manufactured by Toyobo).

支持部材７４は、撥水フィルタ７０及び調湿材７２を取り囲む枠組みからなり、環状の一組の縁部７６と、縁部７６同士を連結する４本の支柱部７８と、一方の縁部７６内の径方向に沿って延在し、支柱部７８同士を互いに交差するように連結する２本の梁部８０とを有する。このように支持部材７４を枠組みから構成することによって、フィルタ部材４６の重量中、支持部材７４が占める重量を低減して、フィルタ部材４６の軽量化を図ることができる。また、撥水フィルタ７０及び調湿材７２が支持部材７４によって覆われる面積を低減できる分、フィルタ部材４６の通気性が低下することを抑制できる。   The support member 74 is composed of a frame surrounding the water repellent filter 70 and the humidity control material 72, and includes a ring-shaped pair of edge portions 76, four support column portions 78 that connect the edge portions 76, and one edge portion 76. It has two beam portions 80 that extend along the inner radial direction and connect the column portions 78 so as to cross each other. By thus configuring the support member 74 from the framework, the weight of the support member 74 in the weight of the filter member 46 can be reduced, and the weight of the filter member 46 can be reduced. Moreover, it can suppress that the air permeability of the filter member 46 falls by the part which can reduce the area where the water-repellent filter 70 and the humidity control material 72 are covered with the support member 74.

なお、本実施形態では、図３Ｂに示すように、撥水フィルタ７０の内部の円柱形状の空間全体に調湿材７２が収容されている。このため、支持部材７４で支持された撥水フィルタ７０及び調湿材７２を、キャップ４４とフランジ部５４との間の空間に配設することで、通気孔５６の他端側の開口５８全体が、撥水フィルタ７０で覆われるとともに、該撥水フィルタ７０を介して調湿材７２で覆われる。   In this embodiment, as shown in FIG. 3B, the humidity control material 72 is accommodated in the entire cylindrical space inside the water repellent filter 70. For this reason, by disposing the water repellent filter 70 and the humidity control material 72 supported by the support member 74 in the space between the cap 44 and the flange portion 54, the entire opening 58 on the other end side of the vent hole 56. Is covered with the water repellent filter 70, and is covered with the humidity control material 72 through the water repellent filter 70.

基本的には上記のように構成される本実施形態に係る電子制御装置１０によれば、貫通孔３０が形成された筐体１２と、該貫通孔３０を通気可能に覆う通気栓１６とを備えることで、筐体１２の内部空間の通気性を高めることができる。このため、電子部品の温度上昇等に伴い、筐体１２の内部空間に温度変化が生じても、該内部空間内の気圧が過度に変化することを抑制でき、これによって、筐体１２等に過大な応力が発生することを回避できる。   Basically, according to the electronic control apparatus 10 according to the present embodiment configured as described above, the casing 12 in which the through hole 30 is formed and the vent plug 16 that covers the through hole 30 so as to allow ventilation. By providing, the air permeability of the internal space of the housing 12 can be enhanced. For this reason, even if a temperature change occurs in the internal space of the housing 12 due to a rise in the temperature of the electronic component, etc., it is possible to suppress the air pressure in the internal space from changing excessively. Excessive stress can be avoided.

また、このようにして内部空間の通気性を高めても、通気孔５６が撥水フィルタ７０に覆われることで、筐体１２の外部から通気孔５６を介して内部空間に液体の水等が侵入することを回避できるため、該内部空間の防水性が低下することを回避できる。   Even if the air permeability of the internal space is improved in this way, the water hole is covered with the water repellent filter 70, so that liquid water or the like can be supplied from the outside of the housing 12 to the internal space via the air hole 56. Since it can avoid entering, it can avoid that the waterproofness of this internal space falls.

さらに、この電子制御装置１０によれば、長期間にわたって良好に内部空間の湿度が上昇することを抑制できる。すなわち、例えば、筐体１２の内部空間の温度が降下する等して、該内部空間の内圧が外圧に比して小さくなるような場合、筐体１２の外側の空気が通気栓１６を介して内部空間に流入する。具体的には、先ず、筐体１２の外側から、フィルタ部材４６とキャップ４４との間に形成された間隙６２を介して、フィルタ部材４６に空気が流入する。   Furthermore, according to this electronic control device 10, it is possible to suppress the humidity in the internal space from rising well over a long period of time. That is, for example, when the internal pressure of the internal space becomes smaller than the external pressure due to a drop in the temperature of the internal space of the housing 12, air outside the housing 12 passes through the vent plug 16. It flows into the internal space. Specifically, first, air flows into the filter member 46 from the outside of the housing 12 through a gap 62 formed between the filter member 46 and the cap 44.

フィルタ部材４６の撥水フィルタ７０は、液体の通過を阻止するため、たとえ、空気とともに液体の水が前記間隙６２を介してフィルタ部材４６に到達したとしても、該液体の水が撥水フィルタ７０を通過することは阻止される。これによって、筐体１２の内部空間に液体の水が侵入することを回避できる。   The water repellent filter 70 of the filter member 46 prevents the liquid from passing through. Therefore, even if the liquid water together with the air reaches the filter member 46 through the gap 62, the water of the liquid repels the water repellent filter 70. Passing through is blocked. As a result, liquid water can be prevented from entering the internal space of the housing 12.

一方、フィルタ部材４６の撥水フィルタ７０は、気体が通過することを許容する。このため、フィルタ部材４６に流入した空気は、撥水フィルタ７０を通過して、その内部に収容された調湿材７２に到達する。そして、空気が調湿材７２を通過する過程で、該空気中の水蒸気成分が吸収される。したがって、筐体１２の内部空間に対し、水蒸気の侵入を抑制しつつ、空気を流入させることができるため、該内部空間の湿度が上昇することを抑制できる。   On the other hand, the water repellent filter 70 of the filter member 46 allows gas to pass through. For this reason, the air that has flowed into the filter member 46 passes through the water repellent filter 70 and reaches the humidity control material 72 accommodated therein. And in the process in which air passes the humidity control material 72, the water vapor | steam component in this air is absorbed. Therefore, since air can be introduced into the internal space of the housing 12 while suppressing the intrusion of water vapor, it is possible to suppress an increase in the humidity of the internal space.

また、例えば、電子部品の温度上昇等により、筐体１２の内部空間の温度が上昇する等して、該内部空間の内圧が外圧に比して大きくなるような場合、内部空間の空気が通気栓１６を介して筐体１２の外側に排出される。この際、内部空間で加温されることで比較的高温となった空気が、通気孔５６を介してフィルタ部材４６に到達し、調湿材７２を通過する。これによって、調湿材７２に吸収されていた水分が放出される。   For example, when the internal pressure of the internal space becomes larger than the external pressure due to, for example, the temperature of the internal space of the housing 12 rising due to the temperature rise of the electronic components, the air in the internal space is vented. It is discharged to the outside of the housing 12 through the plug 16. At this time, air that has been heated to a relatively high temperature in the internal space reaches the filter member 46 through the vent hole 56 and passes through the humidity control material 72. Thereby, the water | moisture content absorbed in the humidity control material 72 is discharge | released.

この調湿材７２から放出された水分は、空気とともに撥水フィルタ７０を通過して、フィルタ部材４６とキャップ４４との間に形成された間隙６２を介して、筐体１２の外部へと排出される。その結果、調湿材７２を再び水蒸気を良好に吸収することが可能な状態にすること、つまり、調湿材７２の吸湿能力を再生することができる。このため、フィルタ部材４６に対して、特別なメンテナンス等を施すことなく、長期間にわたって良好に内部空間の湿度が上昇することを抑制できる。   Moisture released from the humidity control material 72 passes through the water-repellent filter 70 together with air, and is discharged to the outside of the housing 12 through a gap 62 formed between the filter member 46 and the cap 44. Is done. As a result, the humidity control material 72 can be brought into a state where it can absorb water vapor again, that is, the moisture absorption capacity of the humidity control material 72 can be regenerated. For this reason, it can suppress that the humidity of internal space rises favorably over a long period, without performing special maintenance etc. with respect to the filter member 46. FIG.

以上から、この電子制御装置１０によれば、防水性を高めた筐体１２の内部空間と外部との気圧差を良好に調整できるとともに、該内部空間の湿度上昇を長期的に抑制できる。その結果、電子部品におけるバスバー端子等の金属部に腐食が生じることを回避して、電子制御装置１０の耐久性を向上させることや長寿命化を図ることが可能になる。   As described above, according to the electronic control device 10, it is possible to satisfactorily adjust the pressure difference between the interior space of the casing 12 with improved waterproofness and the outside, and to suppress an increase in humidity in the interior space over a long period of time. As a result, it is possible to improve the durability of the electronic control device 10 and to extend the life by avoiding the occurrence of corrosion in metal parts such as bus bar terminals in the electronic component.

次に、図４Ａ及び図４Ｂを参照しつつ、他の実施形態に係る電子制御装置９０について説明する。図４Ａは、電子制御装置９０の部分拡大断面図であり、図４Ｂは、電子制御装置９０が備えるフィルタ部材９２の部分外観斜視図である。なお、図４Ａ及び図４Ｂに示す構成要素のうち、図１〜図３Ｂに示す構成要素と同一又は同様の機能及び効果を奏するものに対しては、同一の参照符号を付し、詳細な説明を省略する。また、図４Ａ及び図４Ｂでは、支持部材７４の図示を省略している。   Next, an electronic control device 90 according to another embodiment will be described with reference to FIGS. 4A and 4B. 4A is a partially enlarged cross-sectional view of the electronic control device 90, and FIG. 4B is a partial external perspective view of a filter member 92 provided in the electronic control device 90. 4A and 4B, those having the same or similar functions and effects as those shown in FIGS. 1 to 3B are denoted by the same reference numerals, and detailed description thereof is omitted. Is omitted. 4A and 4B, the support member 74 is not shown.

電子制御装置９０は、フィルタ部材４６に代えて、フィルタ部材９２を備えることを除いて、上記の電子制御装置１０と同様に構成されている。このフィルタ部材９２は、撥水フィルタ９４と、調湿材９６と、上記のフィルタ部材４６と同様の支持部材７４とを有している。そこで、以下では、主に、フィルタ部材９２の撥水フィルタ９４及び調湿材９６について、具体的に説明する。   The electronic control unit 90 is configured in the same manner as the electronic control unit 10 except that it includes a filter member 92 instead of the filter member 46. The filter member 92 includes a water repellent filter 94, a humidity control material 96, and a support member 74 similar to the filter member 46 described above. Therefore, in the following, the water-repellent filter 94 and the humidity control material 96 of the filter member 92 will be specifically described.

撥水フィルタ９４は、溝部９８が設けられた中空円柱形状であり、該溝部９８を除く部分の内部に調湿材９６を収容する。具体的には、撥水フィルタ９４は、前記中空円柱形状の軸方向の一端側に、通気孔５６の他端側の開口５８を覆う円形状の壁部１００が設けられる。   The water repellent filter 94 has a hollow cylindrical shape provided with a groove 98, and houses the humidity control material 96 inside the portion excluding the groove 98. Specifically, the water repellent filter 94 is provided with a circular wall portion 100 that covers the opening 58 on the other end side of the vent hole 56 on one end side in the axial direction of the hollow cylindrical shape.

溝部９８は、フィルタ部材９２及びキャップ４４の間に形成された間隙６２と、壁部１００との間に設けられ、これによって、壁部１００を介して通気孔５６と間隙６２とを連通する。すなわち、この撥水フィルタ９４の内部に収容される調湿材９６にも、溝部９８に対応する部位に、壁部１００を介して通気孔５６と間隙６２とを連通する切欠部１０４が形成される。   The groove portion 98 is provided between the wall portion 100 and the gap 62 formed between the filter member 92 and the cap 44, and thereby communicates the vent hole 56 and the gap 62 via the wall portion 100. That is, the humidity control member 96 housed in the water repellent filter 94 is also formed with a notch 104 that communicates the air hole 56 and the gap 62 via the wall 100 at a portion corresponding to the groove 98. The

これらのように構成された撥水フィルタ９４及び調湿材９６は、上記の撥水フィルタ７０及び調湿材７２と同様に、支持部材７４で支持された状態で、キャップ４４とフランジ部５４との間に配設される。したがって、撥水フィルタ９４の壁部１００によって、通気孔５６の外部側の開口５８全体が覆われ、これによって、筐体１２の外部から液体の水が通気孔５６を介して内部空間に侵入することを回避できる。   The water repellent filter 94 and the humidity control material 96 configured as described above are supported by the support member 74 in the same manner as the water repellent filter 70 and the humidity control material 72 described above. Between the two. Therefore, the wall portion 100 of the water repellent filter 94 covers the entire opening 58 on the outside of the vent hole 56, whereby liquid water enters the internal space from the outside of the housing 12 through the vent hole 56. You can avoid that.

また、調湿材９６の切欠部１０４を除く部分によって、前記開口５８が部分的に覆われているため、筐体１２の外部の空気が通気孔５６を介して内部空間に流入する際、該空気に含まれる水蒸気が調湿材９６に吸収される。すなわち、内部空間の湿度が上昇することを抑制できる。一方、内部空間で加温されることで比較的高温となった空気が、筐体１２の外部へ排出される際、該空気が調湿材９６を通過するため、調湿材９６の吸湿能力を再生することができる。   In addition, since the opening 58 is partially covered by the portion excluding the notch 104 of the humidity control material 96, when air outside the housing 12 flows into the internal space through the vent hole 56, the opening 58 Water vapor contained in the air is absorbed by the humidity control material 96. That is, it is possible to suppress an increase in the humidity of the internal space. On the other hand, when air heated to a relatively high temperature in the internal space is discharged to the outside of the housing 12, the air passes through the humidity control material 96. Can be played.

さらに、たとえ、経年劣化等により調湿材９６の通気性が低下した場合であっても、調湿材９６の切欠部１０４を介して空気を良好に流通させることができるため、筐体１２の内部空間の通気性を長期的に維持することができ、ひいては、電子制御装置９０の一層の長寿命化を図ることが可能になる。   Furthermore, even if the air permeability of the humidity control material 96 is lowered due to deterioration over time, air can be circulated through the notch 104 of the humidity control material 96. The air permeability of the internal space can be maintained for a long time, and as a result, the life of the electronic control unit 90 can be further extended.

なお、本発明は、上記した実施形態に特に限定されるものではなく、その要旨を逸脱しない範囲で種々の変形が可能であることは勿論である。   In addition, this invention is not specifically limited to above-described embodiment, Of course, a various deformation | transformation is possible in the range which does not deviate from the summary.

例えば、上記の実施形態では、略円柱形状の撥水フィルタ７０、９４等を備えることでフィルタ部材４６、９２を略円柱形状としたが、特にこれに限定されるものではない。   For example, in the above-described embodiment, the filter members 46 and 92 have a substantially cylindrical shape by including the substantially cylindrical water-repellent filters 70 and 94, but the invention is not particularly limited thereto.

また、上記の実施形態では、支持部材７４が枠組みから構成されることとしたが、特にこれに限定されず、支持部材７４は、フランジ部５４とキャップ４４との間において、フィルタ部材４６、９２の通気性を過度に低下させることなく、撥水フィルタ７０、９４及び調湿材７２、９６を支持することが可能な構成であればよい。   In the above-described embodiment, the support member 74 is configured by the frame. However, the support member 74 is not particularly limited thereto, and the support member 74 is provided between the flange portion 54 and the cap 44 and the filter members 46 and 92. Any structure that can support the water-repellent filters 70 and 94 and the humidity control materials 72 and 96 may be used without excessively reducing the air permeability.
