および図16に示すような従来の太陽電池モジュールの電力リード引き出し装置は、以下のような問題点がある。 And power lead off unit of a conventional solar cell module as shown in FIG. 16, it has the following problems.

【0020】円形若しくは四角形の穴17は、補強層11から接着層7までに切り込みを入れ、穴17内の各層を取り除くことで形成されるが、硬さの異なる層に切り込みを入れる作業が困難である。 The holes 17 of the circular or square, incised from the reinforcing layer 11 to the adhesive layer 7, are formed by removing each layer of the hole 17, difficult task of incisions in different layers of the hardness it is. 補強層は予め穴を開けておくことは可能であるが、接着層7の材料であるE Although the reinforcing layer is possible to be drilled in advance holes, a material of the adhesive layer 7 E
VAはラミネート接着時に熱で溶かして融着させるため、穴をあけても塞がってしまい、また柔らかいために切削加工も出来ない。 VA Since fusing dissolved by heat at the time of lamination adhesive, will be blocked even if a hole, also can not be machined to soft. 加えて補強層11から接着層7までの高さが、ラミネート時の加圧力、加熱温度、加熱時間でEVAの溶け具合が変化するために必ずしも一定でなく、自動化が非常に困難である。 In addition height of the adhesive layer 7 from the reinforcing layer 11 is, pressure applied during lamination, the heating temperature is not necessarily constant for melting condition of EVA changes in heating time, automation is very difficult.

【0021】切り込み後、穴17内の各層を取り除く際、接着層7が電力リード線12に接着しているために剥離が困難で、手作業の削り取りは作業性が悪くて非量産的であり、熱で溶融、蒸発させての除去は周りの各層を損傷する。 [0021] After the cut, when removing each layer of the hole 17, is difficult to peel to the adhesive layer 7 is adhered to the power leads 12, chipping manual is non mass production and poor workability , heat melting, the removal of the evaporated can damage the layers around.

にハンダ付けする際、上記の剥離が完全に行われずに電力リード線12の剥離面にEVAが残っていると、ハンダ付けが出来ない。 When soldering, the above peeling is left EVA on the release surface of the power leads 12 to not completely implemented, can not soldered. 強引にハンダ熱でEVAを蒸発させれば、ハンダ付けは可能であるが、接合信頼性が低く、 If ask forcibly evaporating the EVA in solder heat, is a soldering possible, bonding reliability is low,
EVAを蒸発させるために長時間、ハンダコテをあてているとその熱で周囲の各層を損傷し、また電力リード線12に伝わった熱で、導電性粘着テープなどの渡り線1 Long time to evaporate the EVA, damage the surrounding layers in the thermal and rely on soldering iron, and in heat transferred to the power leads 12, connecting wire such as a conductive adhesive tape 1
3と電力リード線12の接触部が損傷して電気接続が損なわれる。 3 and the electrical connection is impaired contacts of power leads 12 is damaged.

【0023】電力端子箱14を補強層11に取り付けるため、補強層11から電力リード線12に向かって穴17を開け、上記項のハンダ付けを長時間行うと接着層7、9が溶けて電力リード線12が補強層11に近づく。 [0023] For mounting the power terminal box 14 to the reinforcing layer 11, a hole 17 toward the reinforcing layer 11 to the power leads 12, the adhesive layers 7 and 9 is melted and carried out for a long period of time soldering the term power lead 12 approaches the reinforcing layer 11. ここで補強層11が金属性である場合、絶縁層8があるものの熱で劣化して電気絶縁性が損なわれて絶縁抵抗が低下し、最悪時には短絡を起こす。 Here, when the reinforcing layer 11 is metallic, insulating layer 8 deteriorates with is that of heat is impaired electrically insulating insulation resistance is lowered, the worst case cause a short circuit.

【0024】この発明は、上記のような問題点を解消するためになされたもので、本発明の課題は、太陽電池から発電した電力を外部に引出す電力リード線と外部のケーブルとの接合作業が簡便で,信頼性が高く、かつ小型で安価な太陽電池モジュールの電力リード引き出し装置を提供することにある。 [0024] The present invention has been made to solve the above problems, an object of the present invention, the bonding work of the power lead and the external cable to draw the electric power generated from the solar cell to the outside It is simple, reliable, and is to provide a power lead drawer system for a small and inexpensive solar cell modules.
