The waterproof members 52a and 52b are made of, for example, an insulating member such as a silicon-based resin that is cured with time.

防水部材５２ａは、筐体１２と電線口出部材１８との間に設けられている。具体的には、防水部材５２ａは、筐体１２の天板２４の上面と、電線口出部材１８の薄板部４０の水平板部４８の下面との間に設けられている。また、防水部材５２ａは、天板２４の外側の端面２４ｂ、溶接部３８の外面、及び、側板２８の側面部３４の側面３４ｃと、電線口出部材１８の薄板部４０の鉛直板部５０の内面との間に設けられている。これにより、防水部材５２ａは、筐体１２と電線口出部材１８との間、及び、固定穴２４ａ、３２ａ、４８ａ、３４ａ、５０ａを介して、水等が筐体１２の内部に進入することを抑制する。ここで、天板２４の端面２４ｂ、溶接部３８の外面、及び、側板２８の側面３４ｃは、同一平面上に形成されているので、側面部３４の内面との隙間を小さくして、防水部材５２ａが空気等に触れて劣化することを抑制する。   The waterproof member 52 a is provided between the housing 12 and the wire outlet member 18. Specifically, the waterproof member 52 a is provided between the upper surface of the top plate 24 of the housing 12 and the lower surface of the horizontal plate portion 48 of the thin plate portion 40 of the wire outlet member 18. In addition, the waterproof member 52 a includes the outer end surface 24 b of the top plate 24, the outer surface of the welded portion 38, the side surface 34 c of the side surface portion 34 of the side plate 28, and the vertical plate portion 50 of the thin plate portion 40 of the wire outlet member 18.

FIG. 6 is a view of the vicinity of the ground seat 20 as viewed from the outside in the width direction. As shown in FIGS. 5 and 6, a grounding window 34 d is formed on the side surface portion 34 of the side plate 28. A plurality of fixing holes 34 e are formed around the grounding window 34 d of the side surface portion 34 of the side plate 28. The fixing hole 34e is an example of a first fixing hole. The fixing hole 34e extends perpendicularly to the surface direction of the side surface portion 34 and penetrates the side surface portion 34 in the horizontal direction.

アース座２０は、支持部材６０と、貫通部材６２と、防水部材６４と、接地部材６６と、接続部材６８と、一対の取付部材７０ａ、７０ｂとを有する。   The ground seat 20 includes a support member 60, a penetrating member 62, a waterproof member 64, a ground member 66, a connection member 68, and a pair of attachment members 70a and 70b.

The support member 60 is a plate-like member. The area of the support member 60 is larger than the area of the grounding window 34d. The support member 60 is provided on the outer surface of the side plate 28 so as to cover the entire grounding window 34d. A plurality of fixing holes 60 a are formed in the support member 60. The fixing hole 60a is an example of a second fixing hole. The fixing hole 60a extends perpendicularly to the surface direction of the support member 60 and penetrates the support member 60 in the horizontal direction. The fixing hole 60 a is continuous with the fixing hole 34 e in the side surface portion 34 of the side plate 28. As a result, the fixing holes 60 a and 34 e constitute holes that penetrate the support member 60 and the side plate 28. A shaft hole 60 b is formed at the center of the support member 60.

貫通部材６２は、例えば、金属等の導体を含む。貫通部材６２は、例えば、円柱形状である。貫通部材６２は、支持部材６０の軸穴６０ｂに挿入されている。これにより、貫通部材６２は、支持部材６０に支持される。貫通部材６２は、支持部材６０の軸穴６０ｂ及び筐体１２の接地窓３４ｄを貫通して設けられている。貫通部材６２の一端は、筐体１２の外部へ延びる。貫通部材６２の他端は、筐体１２の内部に延びる。貫通部材６２の両端には、ネジ孔６２ａ、６２ｂが形成されている。貫通部材６２のネジ孔６２ａは、アース線等を介して、外部の接地電位（例えば、電車の車両本体の接地電位）と接続される。   The penetrating member 62 includes a conductor such as metal, for example. The penetrating member 62 has, for example, a cylindrical shape. The penetrating member 62 is inserted into the shaft hole 60 b of the support member 60. Thereby, the penetrating member 62 is supported by the support member 60. The penetrating member 62 is provided through the shaft hole 60 b of the support member 60 and the grounding window 34 d of the housing 12. One end of the penetrating member 62 extends to the outside of the housing 12. The other end of the penetrating member 62 extends into the housing 12. Screw holes 62 a and 62 b are formed at both ends of the penetrating member 62. The screw hole 62a of the penetrating member 62 is connected to an external ground potential (for example, the ground potential of the vehicle body of the train) via a ground wire or the like.

防水部材６４は、例えば、樹脂等の絶縁性の材料によって構成される。防水部材６４は、支持部材６０の軸穴６０ｂの周囲に設けられている。これにより、防水部材６４は、支持部材６０と貫通部材６２と間に形成される隙間を塞ぐ。   The waterproof member 64 is made of, for example, an insulating material such as resin. The waterproof member 64 is provided around the shaft hole 60 b of the support member 60. Thereby, the waterproof member 64 closes a gap formed between the support member 60 and the penetrating member 62.

接地部材６６は、例えば、金属等の導体を含む。接地部材６６は、側板２８の側面部３４の内面に設けられている。具体的には、接地部材６６は、側板２８に塗料等が塗布されている場合、当該塗料を除去した状態で、筐体１２の側板２８に設けられる。これにより、接地部材６６は、筐体１２と電気的に接続される。接地部材６６には、ネジ孔６６ａが形成されている。   The ground member 66 includes a conductor such as metal, for example. The ground member 66 is provided on the inner surface of the side surface portion 34 of the side plate 28. Specifically, when a paint or the like is applied to the side plate 28, the grounding member 66 is provided on the side plate 28 of the housing 12 with the paint removed. Thereby, the grounding member 66 is electrically connected to the housing 12. A screw hole 66 a is formed in the ground member 66.

接続部材６８は、例えば、金属等の導体を含む。接続部材６８には、取付孔６８ａ、６８ｂが形成されている。取付孔６８ａは、貫通部材６２のネジ孔６２ｂを露出させる位置に形成されている。取付孔６８ｂは、接地部材６６のネジ孔６６ａを露出させる位置に形成されている。   The connection member 68 includes, for example, a conductor such as metal. Attachment holes 68a and 68b are formed in the connection member 68. The attachment hole 68a is formed at a position where the screw hole 62b of the penetrating member 62 is exposed. The attachment hole 68b is formed at a position where the screw hole 66a of the grounding member 66 is exposed.

取付部材７０ａ、７０ｂは、例えば、金属等の導体を含む。取付部材７０ａ、７０ｂの一例は、ネジである。取付部材７０ａは、接続部材６８の取付孔６８ａに挿入されて、ネジ孔６２ｂと螺合する。取付部材７０ｂは、接続部材６８の取付孔６８ｂに挿入されて、ネジ孔６６ａと螺合する。これにより、接続部材６８は、貫通部材６２と接地部材６６と電気的に接続する。この結果、貫通部材６２と接続されるアース線は、側板２８と電気的に接続されて同電位となる。   The attachment members 70a and 70b include a conductor such as metal, for example. An example of the attachment members 70a and 70b is a screw. The attachment member 70a is inserted into the attachment hole 68a of the connection member 68 and screwed into the screw hole 62b. The attachment member 70b is inserted into the attachment hole 68b of the connection member 68 and screwed into the screw hole 66a. Thereby, the connection member 68 is electrically connected to the penetrating member 62 and the ground member 66. As a result, the ground wire connected to the penetrating member 62 is electrically connected to the side plate 28 and has the same potential.

固定部材２２は、例えば、リベットである。固定部材２２は、支持部材６０の固定穴６０ａ及び側板２８の側面部３４の固定穴３４ｅに挿入されている。固定部材２２の頭部は外側に配置されている。固定部材２２の頭部と反対側の端部は筐体１２の内部に達し、つぶされている。これにより、固定部材２２は、支持部材６０を筐体１２に固定することによって、アース座２０を筐体１２に固定する。   The fixing member 22 is a rivet, for example. The fixing member 22 is inserted into the fixing hole 60 a of the support member 60 and the fixing hole 34 e of the side surface portion 34 of the side plate 28. The head of the fixing member 22 is disposed outside. The end of the fixing member 22 opposite to the head reaches the inside of the housing 12 and is crushed. Thereby, the fixing member 22 fixes the grounding seat 20 to the housing 12 by fixing the support member 60 to the housing 12.

次に、電力変換装置１０の製造方法について説明する。図７及び図８は、電力変換装置１０の製造方法における各工程を説明する図である。   Next, the manufacturing method of the power converter device 10 is demonstrated. 7 and 8 are diagrams for explaining each step in the method for manufacturing the power conversion device 10.

図７に示すように、電気機器１４が設置された筐体１２を準備する。次に、筐体１２の外面（例えば、筐体１２の外面の角部）に、防水部材５２ａが塗布され外面から突出する電線口出部材１８を設置する。   As shown in FIG. 7, the housing 12 in which the electric device 14 is installed is prepared. Next, on the outer surface of the housing 12 (for example, a corner portion of the outer surface of the housing 12), the wire outlet member 18 that is coated with the waterproof member 52a and protrudes from the outer surface is installed.

図８に示すように、筐体１２及び電線口出部材１８に連続して形成された固定穴４８ａ、２４ａ、３２ａ、及び、固定穴５０ａ、３４ａに固定部材２２を挿入する。   As shown in FIG. 8, the fixing member 22 is inserted into the fixing holes 48a, 24a, 32a and the fixing holes 50a, 34a formed continuously in the housing 12 and the wire outlet member 18.

この後、図３等に示すように、固定部材２２の頭部と反対側の端部をつぶしてかしめる。これにより、固定部材２２によって電線口出部材１８を筐体１２に固定する。次に、防水部材５２ｂを固定部材２２及び薄板部４０の外周等に形成する。この後、同様に、アース座２０を固定部材２２によって筐体１２に固定する。これにより、電力変換装置１０が完成する。   Then, as shown in FIG. 3 etc., the edge part on the opposite side to the head of the fixing member 22 is crushed and crimped. Thereby, the wire outlet member 18 is fixed to the housing 12 by the fixing member 22. Next, the waterproof member 52 b is formed on the outer periphery of the fixing member 22 and the thin plate portion 40. Thereafter, similarly, the ground seat 20 is fixed to the housing 12 by the fixing member 22. Thereby, the power converter device 10 is completed.

上述したように、電力変換装置１０では、筐体１２及び電線口出部材１８を貫通する固定部材２２によって、電線口出部材１８を筐体１２に固定している。これにより、電力変換装置１０では、熱を使用する溶接等によらず電線口出部材１８を筐体１２に固定できる。この結果、電力変換装置１０では、筐体１２に熱に弱い電気機器１４を組み込んだ状態で電線口出部材１８を固定できるので、製造工程の自由度を向上させることができる。   As described above, in the power conversion device 10, the wire lead member 18 is fixed to the housing 12 by the fixing member 22 that penetrates the housing 12 and the wire lead member 18. Thereby, in the power converter 10, the electric wire outlet member 18 can be fixed to the housing | casing 12 irrespective of the welding etc. which use heat. As a result, in the power converter 10, since the electric wire outlet member 18 can be fixed in a state in which the heat sensitive electric device 14 is incorporated in the housing 12, the degree of freedom in the manufacturing process can be improved.

このように、電力変換装置１０では、筐体１２から突出する電線口出部材１８及びアース座２０を搬送した後で組み立てることできる。従って、電力変換装置１０では、例えば、外国で筐体１２に電気機器１４を設置して、筐体１２から突出する電線口出部材１８及びアース座２０を自国で組み付けることができる。これにより、電力変換装置１０では、筐体１２から部品が突出しない状態で搬送できるので、コンテナ等の規格に適した状態で搬送できる。この結果、電力変換装置１０では、コンテナ等の規格外の場合に必要な輸送費を削減できる。   Thus, in the power converter 10, it can assemble after conveying the electric wire outlet member 18 and the ground seat 20 which protrude from the housing | casing 12. FIG. Therefore, in the power converter 10, for example, the electric device 14 can be installed in the housing 12 in a foreign country, and the wire outlet member 18 and the ground seat 20 protruding from the housing 12 can be assembled in the home country. Thereby, in the power converter device 10, since it can convey in the state which components do not protrude from the housing | casing 12, it can be conveyed in the state suitable for standards, such as a container. As a result, the power conversion device 10 can reduce the transportation cost required when the container is out of the standard.

電力変換装置１０では、筐体１２と電線口出部材１８の薄板部４０との間に防水部材５２ａを設けているので、筐体１２の内部に水等が侵入することを抑制できる。   In the power conversion device 10, since the waterproof member 52 a is provided between the housing 12 and the thin plate portion 40 of the electric wire outlet member 18, it is possible to suppress water and the like from entering the inside of the housing 12.

電力変換装置１０では、筐体１２の側面を構成する天板２４の外側の一端面と側板２８の側面部３４の側面とを同一平面上に形成している。これにより、天板２４の外側の端面及び側面部３４の側面と、薄板部４０との間の隙間を小さくすることができる。これにより、電力変換装置１０では、筐体１２と薄板部４０との間に設けられた防水部材５２ａが空気等に触れることを抑制できるので、防水部材５２ａの劣化を抑制できる。更に、電力変換装置１０では、溶接部３８を天板２４の外側の端面及び側面部３４の側面と同一面とすることによって、筐体１２の強度を溶接部３８によって向上しつつ、防水部材５２ａの劣化をより抑制できる。   In the power conversion device 10, one end surface on the outer side of the top plate 24 constituting the side surface of the housing 12 and the side surface of the side surface portion 34 of the side plate 28 are formed on the same plane. Thereby, the clearance gap between the outer end surface of the top plate 24, the side surface of the side part 34, and the thin plate part 40 can be made small. Thereby, in the power converter 10, since it can suppress that the waterproof member 52a provided between the housing | casing 12 and the thin-plate part 40 touches air etc., degradation of the waterproof member 52a can be suppressed. Furthermore, in the power converter 10, by making the welded portion 38 flush with the outer end surface of the top plate 24 and the side surface of the side surface portion 34, the strength of the housing 12 is improved by the welded portion 38, and the waterproof member 52a. Can be further suppressed.

電力変換装置１０では、アース座２０が、外部の接地電位と接続される貫通部材６２と、筐体１２と接続された接地部材６６とを接続している。これにより、アース座２０が、固定部材２２によって固定されて、筐体１２の塗料等によって接地することが難しい場合でも、確実に貫通部材６２を筐体１２の接地電位と接続できる。   In the power conversion device 10, the ground seat 20 connects a penetrating member 62 connected to an external ground potential and a grounding member 66 connected to the housing 12. Thereby, even when the grounding seat 20 is fixed by the fixing member 22 and it is difficult to ground by the paint or the like of the housing 12, the penetrating member 62 can be reliably connected to the ground potential of the housing 12.

電力変換装置１０の製造方法では、熱等を使用せずに固定部材２２によって電線口出部材１８を筐体１２に設置できるので、電気機器１４を筐体１２に先に組み込んだ状態で電線口出部材１８を固定できる。この結果、電力変換装置１０の製造方法では、外国で筐体１２に電気機器１４を組み付けてから搬送時に障害になる電線口出部材１８を自国で固定することができる。   In the method for manufacturing the power conversion device 10, the wire outlet member 18 can be installed in the housing 12 by the fixing member 22 without using heat or the like. The exit member 18 can be fixed. As a result, in the method for manufacturing the power conversion device 10, the electric wire outlet member 18 that becomes an obstacle during transportation after the electric device 14 is assembled to the housing 12 in a foreign country can be fixed in the home country.
