The reinforcing frame 3 is attached to the frame-shaped frame 10 so as to span the pair of long- side frames 1, 1 facing the frame-shaped frame 10 at a position where the cushioning material 35 is sandwiched between the reinforcing frame 3.
　図４に示すように、緩衝材３５は、太陽電池パネル２０が図４中に矢印Ｆで示すように正面側から圧力を受けてたわんでも太陽電池パネル２０の裏面が補強フレーム３と接触しない大きさの間隙を形成する高さを有している。 As shown in FIG. 4, the cushioning material 35 is large enough that the back surface of the solar cell panel 20 does not come into contact with the reinforcing frame 3 even when the solar cell panel 20 is bent under pressure from the front side as indicated by an arrow F in FIG. And a height that forms a gap.
　次に、図５から図７を用いて本発明の実施の形態にかかる太陽電池モジュール５０の緩衝材３５について説明する。図５は、実施の形態にかかる太陽電池モジュールの緩衝材の斜視図である。緩衝材３５は、補強フレーム３が接触する平面部３６と、雌型出力コネクタ２３が嵌合する雄型嵌合部３８及び雄型出力コネクタ２４が嵌合する雌型嵌合部３９とを有している。緩衝材３５は、平面部３６と雄型嵌合部３８と雌型嵌合部３９とを一つの金型で成形することが好ましいが、平面部３６と雄型嵌合部３８と雌型嵌合部３９とを別々に成形し、接着剤又は嵌合構造を用いて平面部３６に雄型嵌合部３８及び雌型嵌合部３９を固定した構造であってもよい。 Next, the buffer material 35 of the solar cell module 50 according to the embodiment of the present invention will be described with reference to FIGS. FIG. 5 is a perspective view of the buffer material of the solar cell module according to the embodiment. The cushioning material 35 has a flat surface portion 36 with which the reinforcing frame 3 contacts, a male fitting portion 38 with which the female output connector 23 is fitted, and a female fitting portion 39 with which the male output connector 24 is fitted. is doing. The cushioning material 35 is preferably formed by molding the flat portion 36, the male fitting portion 38, and the female fitting portion 39 with a single mold, but the flat portion 36, the male fitting portion 38, and the female fitting. A structure in which the mating portion 39 and the mating portion 39 are separately molded and the male fitting portion 38 and the female fitting portion 39 are fixed to the flat portion 36 using an adhesive or a fitting structure may be used.
　図６は、実施の形態にかかる太陽電池モジュールの緩衝材と雄型出力コネクタ及び雌型出力コネクタとの嵌合前の状態を示す図である。図６中に矢印で示す方向から雌型出力コネクタ２３を雄型嵌合部３８に押し込み、雄型出力コネクタ２４を雌型嵌合部３９に押し込むことによって、雌型出力コネクタ２３と雄型嵌合部３８を嵌合させ、かつ雄型出力コネクタ２４と雌型嵌合部３９とを嵌合させる。 FIG. 6 is a diagram illustrating a state before the buffer material of the solar cell module according to the embodiment is fitted to the male output connector and the female output connector. The female output connector 23 is pushed into the male fitting portion 38 from the direction indicated by the arrow in FIG. 6, and the male output connector 24 is pushed into the female fitting portion 39, whereby the female output connector 23 and the male fitting are fitted. The mating portion 38 is fitted, and the male output connector 24 and the female fitting portion 39 are fitted.
　図７は、実施の形態にかかる太陽電池モジュールの緩衝材と雄型出力コネクタ及び雌型出力コネクタとの嵌合後の状態を示す図である。雌型出力コネクタ２３は雄型嵌合部３８に、雄型出力コネクタ２４は雌型嵌合部３９に嵌合されており、第１の出力ケーブル２１及び第２の出力ケーブル２２の垂れ下がりを防止することができる。さらに、雌型出力コネクタ２３及び雄型出力コネクタ２４の端子が空気に暴露されないため、空気中の水分による腐食を抑制することができる。 FIG. 7 is a diagram illustrating a state after the buffer material of the solar cell module according to the embodiment is fitted to the male output connector and the female output connector. The female output connector 23 is fitted to the male fitting portion 38 and the male output connector 24 is fitted to the female fitting portion 39 to prevent the first output cable 21 and the second output cable 22 from drooping. can do. Furthermore, since the terminals of the female output connector 23 and the male output connector 24 are not exposed to air, corrosion due to moisture in the air can be suppressed.
　なお、雌型出力コネクタ２３及び雄型出力コネクタ２４が係合構造を備えるのであれば、雄型嵌合部３８及び雌型嵌合部３９に同様の構造を設けることで、雌型出力コネクタ２３が雄型嵌合部３８から脱落したり、雄型出力コネクタ２４が雌型嵌合部から脱落したりしにくい構造を実現できる。係合構造には、雌型出力コネクタ２３及び雄型出力コネクタ２４の一方に爪を設け、他方に溝を設け、爪と溝とを係合させる構造を適用できる。すなわち、雌型出力コネクタ２３及び雄型出力コネクタ２４の一方に爪が設けられ、他方に溝が設けられている場合には、雄型嵌合部３８及び雌型嵌合部３９の一方に爪を設け、他方に溝を設けることで、雄型出力コネクタ２４が雌型嵌合部３９から脱落しにくく、かつ雌型出力コネクタ２３が雄型嵌合部３８から脱落しにくい構造とすることができる。 If the female output connector 23 and the male output connector 24 have an engagement structure, the female output connector 23 is provided by providing the male fitting portion 38 and the female fitting portion 39 with the same structure. However, it is possible to realize a structure in which it is difficult for the male output connector 24 to fall off from the male fitting portion 38 and the male output connector 24 to drop off from the female fitting portion. As the engagement structure, a structure in which a claw is provided on one of the female output connector 23 and the male output connector 24, a groove is provided on the other, and the claw and the groove are engaged can be applied. That is, when a claw is provided on one of the female output connector 23 and the male output connector 24 and a groove is provided on the other, a claw is provided on one of the male fitting portion 38 and the female fitting portion 39. By providing a groove on the other side, the male output connector 24 is less likely to drop off from the female fitting portion 39, and the female output connector 23 is less likely to drop off from the male fitting portion 38. it can.
　このように、実施の形態にかかる太陽電池モジュールは、製造コストを大幅に増大させることなく第１及び第２の出力ケーブルの垂れ下がり及び出力コネクタの腐食を抑制できる。 As described above, the solar cell module according to the embodiment can suppress the sagging of the first and second output cables and the corrosion of the output connector without significantly increasing the manufacturing cost.
　なお、雄型嵌合部３８及び雌型嵌合部３９にパッキンを設け、雌型出力コネクタ２３及び雄型出力コネクタ２４を嵌合させた際に、端子部分が気密封止されるようにすることで、端子の耐腐食性をさらに高めることができる。 In addition, packing is provided in the male fitting portion 38 and the female fitting portion 39 so that the terminal portion is hermetically sealed when the female output connector 23 and the male output connector 24 are fitted. Thus, the corrosion resistance of the terminal can be further increased.
　以上の実施の形態に示した構成は、本発明の内容の一例を示すものであり、別の公知の技術と組み合わせることも可能であるし、本発明の要旨を逸脱しない範囲で、構成の一部を省略、変更することも可能である。 The configuration described in the above embodiment shows an example of the contents of the present invention, and can be combined with another known technique, and can be combined with other configurations without departing from the gist of the present invention.
