（実施例１）
本発明を具体的に説明する前に、概要を述べる。本発明の実施例１は、太陽電池パネルの外縁部を囲むように複数のフレームを取り付けた太陽電池モジュールに関する。フレームは中空構造を有しており、隣接したフレームを連結するための連結部材がフレーム内に挿入される。また、フレームには貫通孔が設けられるとともに、連結部材には被挿入部が設けられており、接合部材は、貫通孔と被挿入部に連続的に挿入されることによって、連結部材とフレームとを固定する。このように貫通孔と被挿入部に接合部材を挿入することによって、フレームを連結する場合、加工公差の制約を考慮しながら、接合部材の挿入を容易にするために、フレームの貫通孔は長穴形状に形成される。 Example 1
Before describing the present invention in detail, an outline will be described. Example 1 of this invention is related with the solar cell module which attached the some flame | frame so that the outer edge part of a solar cell panel might be enclosed. The frame has a hollow structure, and a connecting member for connecting adjacent frames is inserted into the frame. Further, the frame is provided with a through hole, and the connecting member is provided with an insertion portion. The joining member is continuously inserted into the through hole and the insertion portion, so that the connection member and the frame are connected to each other. To fix. When the frame is connected by inserting the joining member into the through hole and the insertion portion in this way, the through hole of the frame is long in order to facilitate the insertion of the joining member while taking into account the constraints of processing tolerances. It is formed in a hole shape.

しかしながら、長穴形状にすることによって、接合部材による固定の強度が弱くなり、連結したフレームにはガタツキが発生しやすくなる。連結したフレームにおけるガタツキの発生を抑制するために、本実施例に係る連結部材は、被挿入部に接合部材が挿入された場合に、フレームの対向した２つの内壁に接触するように変形する。この接触により、連結部材の移動が制限されるので、ガタツキの発生が抑制される。なお、以下の説明において、「平行」、「垂直」は、完全な平行、垂直だけではなく、誤差の範囲で平行、垂直からずれている場合も含むものとする。また、「略」は、おおよその範囲で同一であるという意味である。   However, by adopting the long hole shape, the strength of fixing by the joining member is weakened, and rattling is likely to occur in the connected frames. In order to suppress the occurrence of rattling in the connected frames, the connecting member according to the present embodiment is deformed so as to come into contact with the two inner walls facing each other when the joining member is inserted into the inserted portion. Due to this contact, the movement of the connecting member is restricted, so that the occurrence of rattling is suppressed. In the following description, “parallel” and “vertical” include not only perfect parallel and vertical, but also include cases in which they deviate from parallel and vertical within an error range. Further, “substantially” means that they are the same in an approximate range.

図１（ａ）−（ｂ）は、本発明の実施例１に係る太陽電池モジュール１００の構成を示す。図１（ａ）は、太陽電池モジュール１００を受光面側から見た場合の構成を示す。太陽電池モジュール１００は、短フレーム１０と総称される第１短フレーム１０ａ、第２短フレーム１０ｂ、長フレーム１２と総称される第１長フレーム１２ａ、第２長フレーム１２ｂ、太陽電池パネル１１０を含む。   Fig.1 (a)-(b) shows the structure of the solar cell module 100 which concerns on Example 1 of this invention. Fig.1 (a) shows the structure at the time of seeing the solar cell module 100 from the light-receiving surface side. The solar cell module 100 includes a first short frame 10a, a second short frame 10b, which are collectively referred to as a short frame 10, a first long frame 12a, a second long frame 12b, which are collectively referred to as a long frame 12, and a solar cell panel 110. .

図１（ａ）に示すように、ｘ軸、ｙ軸、ｚ軸からなる直交座標系が規定される。ｘ軸、ｙ軸は、太陽電池モジュール１００の平面内において互いに直交する。ｚ軸は、ｘ軸およびｙ軸に垂直であり、太陽電池モジュール１００の厚み方向に延びる。また、ｘ軸、ｙ軸、ｚ軸のそれぞれの正の方向は、図１（ａ）における矢印の方向に規定され、負の方向は、矢印と逆向きの方向に規定される。太陽電池モジュール１００を形成する２つの主表面であって、かつｘ−ｙ平面に平行な２つの主表面のうち、ｚ軸の正方向側に配置される主平面が受光面１１２であり、ｚ軸の負方向側に配置される主平面が裏面１１４である。以下では、ｚ軸の正方向側を「受光面側」とよび、ｚ軸の負方向側を「裏面側」とよぶ。   As shown in FIG. 1A, an orthogonal coordinate system including an x axis, a y axis, and a z axis is defined. The x axis and the y axis are orthogonal to each other in the plane of the solar cell module 100. The z axis is perpendicular to the x axis and the y axis and extends in the thickness direction of the solar cell module 100. Further, the positive directions of the x-axis, y-axis, and z-axis are each defined in the direction of the arrow in FIG. 1A, and the negative direction is defined in the direction opposite to the arrow. Of the two main surfaces forming the solar cell module 100 and parallel to the xy plane, the main plane disposed on the positive side of the z-axis is the light receiving surface 112, and z A main plane disposed on the negative direction side of the shaft is the back surface 114. Hereinafter, the positive direction side of the z-axis is referred to as “light-receiving surface side”, and the negative direction side of the z-axis is referred to as “back surface side”.

太陽電池パネル１１０は、ｚ軸方向に互いに反対を向いた受光面１１２と裏面１１４を含みながら、ｙ軸方向よりもｘ軸方向に長い矩形状を有する。太陽電池パネル１１０の受光面１１２側には透光性基板が配置され、裏面１１４側には裏面保護部材であるバックシートが配置される。また、透光性基板とバックシートとの間には、封止部材が配置されており、封止部材によって複数の太陽電池セルが封止されている。例えば、透光性基板には、ガラス基板、透光性プラスチック等が使用され、バックシートには、ＰＥＴ（ポリエチレンテレフタラート）等の樹脂フィルム、Ａｌ箔を樹脂フィルムで挟んだ構造を有する積層フィルムが使用される。また、封止部材には、ポリオレフィン、ＥＶＡ（エチレンビニルアセテート）、ＰＶＢ（ポリビニルブチラール）、ポリイミド等の樹脂フィルムのような熱可塑性樹脂が使用される。   The solar cell panel 110 has a rectangular shape that is longer in the x-axis direction than in the y-axis direction, while including the light receiving surface 112 and the back surface 114 that are opposite to each other in the z-axis direction. A translucent substrate is disposed on the light receiving surface 112 side of the solar cell panel 110, and a back sheet as a back surface protection member is disposed on the back surface 114 side. Moreover, the sealing member is arrange | positioned between the translucent board | substrate and the back sheet | seat, and the several photovoltaic cell is sealed with the sealing member. For example, a glass substrate, a translucent plastic, etc. are used for a translucent substrate, a back film is a resin film such as PET (polyethylene terephthalate), and a laminated film having a structure in which an Al foil is sandwiched between resin films. Is used. For the sealing member, a thermoplastic resin such as a resin film such as polyolefin, EVA (ethylene vinyl acetate), PVB (polyvinyl butyral), or polyimide is used.

太陽電池パネル１１０のｘ軸方向の両端には、ｙ軸方向に延びる短フレーム１０が配置され、太陽電池パネル１１０のｙ軸方向の両端には、ｘ軸方向に延びる長フレーム１２が配置される。隣接した短フレーム１０と長フレーム１２は互いに連結されることによって、２つの短フレーム１０と２つの長フレーム１２は、太陽電池パネル１１０の外縁部を囲むような枠形状に配置される。短フレーム１０と長フレーム１２は、押出成形によって形成されるので、延びる方向を横切る方向において同一形状の断面を有する。また、短フレーム１０と長フレーム１２は、太陽電池パネル１１０を保護するために、例えば、アルミニウム、あるいはアルミニウム合金で構成される。   The short frames 10 extending in the y-axis direction are arranged at both ends in the x-axis direction of the solar cell panel 110, and the long frames 12 extending in the x-axis direction are arranged at both ends in the y-axis direction of the solar cell panel 110. . The adjacent short frame 10 and the long frame 12 are connected to each other, so that the two short frames 10 and the two long frames 12 are arranged in a frame shape so as to surround the outer edge portion of the solar cell panel 110. Since the short frame 10 and the long frame 12 are formed by extrusion molding, they have a cross section having the same shape in a direction crossing the extending direction. Further, the short frame 10 and the long frame 12 are made of, for example, aluminum or an aluminum alloy in order to protect the solar cell panel 110.

なお、太陽電池パネル１１０の裏面１１４には、図示しない端子ボックスが取り付けられる。また、２本のケーブルのそれぞれの一端側は、端子ボックスに接続され、２本のケーブルのそれぞれの他端側には、コネクタが接続される。端子ボックス、ケーブル、コネクタは、太陽電池パネル１１０に電気的に接続され、太陽電池パネルから電力を取り出す。太陽電池パネル１１０に短フレーム１０、長フレーム１２、端子ボックス、ケーブル、コネクタを取り付けたものが、太陽電池モジュール１００であるが、以下では、端子ボックス、ケーブル、コネクタの説明を省略する。   A terminal box (not shown) is attached to the back surface 114 of the solar cell panel 110. One end of each of the two cables is connected to the terminal box, and a connector is connected to the other end of each of the two cables. The terminal box, cable, and connector are electrically connected to the solar cell panel 110 and take out power from the solar cell panel. A solar cell module 100 is obtained by attaching the short frame 10, the long frame 12, the terminal box, the cable, and the connector to the solar cell panel 110, but the description of the terminal box, the cable, and the connector is omitted below.

図１（ｂ）は、図１（ａ）における太陽電池モジュール１００のｘ軸、具体的にはＡ−Ａ’線に沿った断面図である。太陽電池パネル１１０は、ｚ軸方向よりもｘ軸方向に長い形状を有し、ｚ軸の正方向側に受光面１１２を向け、ｚ軸の負方向側に裏面１１４を向けて配置される。また、太陽電池パネル１１０のｘ軸の正方向側端と、ｘ軸の負方向側端のそれぞれは、前述の外縁部１１６に相当する。   FIG. 1B is a cross-sectional view of the solar cell module 100 in FIG. 1A along the x axis, specifically, the A-A ′ line. The solar cell panel 110 has a shape that is longer in the x-axis direction than the z-axis direction, and is arranged with the light receiving surface 112 facing the positive direction side of the z-axis and the back surface 114 facing the negative direction side of the z-axis. Further, each of the positive end on the x-axis side and the negative end on the x-axis side of the solar cell panel 110 corresponds to the outer edge portion 116 described above.

第１短フレーム１０ａと第２短フレーム１０ｂとは、左右対称ではあるが、同様に構成されるので、以下では、第１短フレーム１０ａをもとに説明する。なお、図示しない長フレーム１２も、短フレーム１０と同様に構成されてもよい。第１短フレーム１０ａ、第２短フレーム１０ｂを総称する短フレーム１０は、嵌合部２０、支持部２２、脚部２４、底部２６を含み、支持部２２は、天面部２８、第１中空部３０、第２中空部３２、仕切片３４と総称される第１仕切片３４ａ、第２仕切片３４ｂ、底面部４０を含む。ここで、嵌合部２０、支持部２２、脚部２４、底部２６は、一体的に形成される。   The first short frame 10a and the second short frame 10b are bilaterally symmetric, but are configured in the same manner, and therefore will be described below based on the first short frame 10a. The long frame 12 (not shown) may be configured similarly to the short frame 10. The short frame 10 collectively referring to the first short frame 10a and the second short frame 10b includes a fitting portion 20, a support portion 22, a leg portion 24, and a bottom portion 26.

A top surface portion 28 is disposed on the positive side of the support portion 22 in the z-axis direction so as to face the fitting portion 20. The support portion 22 has a substantially rectangular cross section, and includes a first partition piece 34a and a second partition piece 34b facing the inner wall 42 of a hollow structure. The hollow structure is divided into the first hollow portion 30 and the second hollow portion 32 by the first partition piece 34a and the second partition piece 34b. In the bottom surface portion 40 of the support portion 22 on the negative side of the z axis, legs 24 are provided from the negative direction side of the x axis toward the negative direction of the z axis. Note that the leg portion 24 may be connected to any portion of the bottom surface portion 40. A bottom portion 26 is disposed on the negative side of the z-axis of the leg portion 24. The bottom portion 26 has a cross section extending in the x-axis direction, and supports the leg portion 24 from the negative direction side of the z-axis.

These are enlarged views of a portion where the first short frame 10a and the first long frame 12a are adjacent to each other in FIG. 1A, and show a configuration when viewed from the light receiving surface side. The first short frame 10a extending in the y-axis direction and the first long frame 12a extending in the x-axis direction are joined at a substantially right angle. Moreover, the 1st short frame 10a and the 1st long frame 12a are connected by inserting the connection member 200 in them. Although the connecting member 200 is not visible from the light receiving surface side and the back surface side of the solar cell module 100, here, in order to explain the configuration of the connecting member 200, the connecting member 200 is shown by a solid line, and the first short frame 10a, the first The long frame 12a is indicated by a dotted line.

図２（ａ）は、接合部材３００を挿入する前の構成、すなわち第１短フレーム１０ａと第１長フレーム１２ａに連結部材２００を挿入した直後の構成を示す。連結部材２００は、ｘ軸方向に延びる第１連結片２１０ａと、ｙ軸方向に延びる第２連結片２１０ｂとが略直角に結合したＬ字型の形状を有する。このような第１連結片２１０ａと第２連結片２１０ｂは結合されて一体的に形成される。第１連結片２１０ａは、ｙ軸の正方向側においてｘ軸方向に延びる第１内側縁部２１４ａと、ｙ軸の負方向側においてｘ軸方向に延びる第１外側縁部２１６ａとに挟まれる。また、第１連結片２１０ａのｘ軸の負方向側には、鋭角をなす形状に形成された第１先頭部２１２ａが配置される。このような構成によって、第１連結片２１０ａは、第１長フレーム１２ａの内部に挿入される。具体的に説明すると、第１長フレーム１２ａにおける支持部２２の第２中空部３２に第１連結片２１０ａが挿入される。ここで、第１連結片２１０ａのｙ軸方向の幅は、第２中空部３２のｙ軸方向の幅よりも小さくされる。   FIG. 2A shows a configuration before the joining member 300 is inserted, that is, a configuration immediately after the connecting member 200 is inserted into the first short frame 10a and the first long frame 12a. The connecting member 200 has an L-shaped shape in which a first connecting piece 210a extending in the x-axis direction and a second connecting piece 210b extending in the y-axis direction are coupled at a substantially right angle. The first connection piece 210a and the second connection piece 210b are combined and integrally formed. The first connecting piece 210a is sandwiched between a first inner edge 214a that extends in the x-axis direction on the positive direction side of the y-axis and a first outer edge 216a that extends in the x-axis direction on the negative direction side of the y-axis. A first leading portion 212a formed in an acute angle shape is disposed on the negative direction side of the first connecting piece 210a on the x axis. With such a configuration, the first connecting piece 210a is inserted into the first long frame 12a. Specifically, the first connecting piece 210a is inserted into the second hollow portion 32 of the support portion 22 in the first long frame 12a. Here, the width of the first connecting piece 210a in the y-axis direction is made smaller than the width of the second hollow portion 32 in the y-axis direction.

第２連結片２１０ｂは、第１連結片２１０ａと同様に、ｘ軸の負方向側においてｙ軸方向に延びる第２内側縁部２１４ｂと、ｘ軸の正方向側においてｙ軸方向に延びる第２外側縁部２１６ｂとに挟まれるとともに、第２先頭部２１２ｂを有する。このような構成によって、第２連結片２１０ｂは、第１短フレーム１０ａの内部に挿入される。具体的に説明すると、第１短フレーム１０ａにおける支持部２２の第２中空部３２に第２連結片２１０ｂが挿入される。ここでも、第２連結片２１０ｂのｘ軸方向の幅は、第２中空部３２のｘ軸方向の幅よりも小さくされる。つまり、フレームに連結片２１０が挿入されることによって、連結部材２００は隣接したフレームを連結する。   Similarly to the first connection piece 210a, the second connection piece 210b has a second inner edge 214b extending in the y-axis direction on the negative direction side of the x-axis and a second extension extending in the y-axis direction on the positive direction side of the x-axis. It is sandwiched between the outer edge portion 216b and has a second leading portion 212b. With such a configuration, the second connection piece 210b is inserted into the first short frame 10a. Specifically, the second connecting piece 210b is inserted into the second hollow portion 32 of the support portion 22 in the first short frame 10a. Again, the width of the second connecting piece 210b in the x-axis direction is made smaller than the width of the second hollow portion 32 in the x-axis direction. That is, when the connecting piece 210 is inserted into the frame, the connecting member 200 connects adjacent frames.

このような状態において、接合部材３００が挿入されるが、ここでは、接合部材３００の構成と、接合部材３００を挿入するための構成を説明するために、図３も使用する。図３は、短フレーム１０と連結部材２００とが接合部材３００によって接合された構成を示す断面図である。これは、図２（ａ）における太陽電池モジュール１００に接合部材３００が挿入された場合のｘ軸、具体的にはＢ−Ｂ’線に沿った断面図である。図３において、太陽電池パネル１１０は省略される。なお、第１連結片２１０ａに接合される接合部材３００を第１接合部材３００ａとし、第２連結片２１０ｂに接合される接合部材３００を第２接合部材３００ｂとするが、これらの構成は共通であるので、以下では接合部材３００とすることもある。また、短フレーム１０と長フレーム１２において、接合部材３００を挿入するための構成も共通である。   In such a state, the joining member 300 is inserted. Here, FIG. 3 is also used to explain the configuration of the joining member 300 and the configuration for inserting the joining member 300. FIG. 3 is a cross-sectional view showing a configuration in which the short frame 10 and the connecting member 200 are joined by the joining member 300. This is a cross-sectional view taken along the x-axis, specifically the B-B ′ line, when the joining member 300 is inserted into the solar cell module 100 in FIG. In FIG. 3, the solar cell panel 110 is omitted. In addition, although the joining member 300 joined to the 1st connection piece 210a is made into the 1st joining member 300a, and the joining member 300 joined to the 2nd connection piece 210b is made into the 2nd joining member 300b, these structures are common. Therefore, in the following, the joining member 300 may be used. Further, the short frame 10 and the long frame 12 have the same configuration for inserting the joining member 300.

接合部材３００の一例は、リベットである。リベットは、穴をあけた部材に差し込んで専用の工具でかしめることによって反対側の端部を塑性変形させて接合させる部品であり、頭部３１０、胴部３１２を含む。頭部３１０は、半球形の丸頭、円盤状の平頭、表面側が平で根元が円錐形の皿頭のいずれであってもよいが、ここでは丸頭であるとする。また、胴部３１２は、円筒形に形成される。ここで、頭部３１０の最も大きい部分の径は、胴部３１２の径よりも大きくなっているので、接合部材３００を胴部３１２から差し込んだ場合に、頭部３１０によって接合部材３００の進入が止められる。なお、接合部材３００は、リベットではなく、ねじであってもよい。その場合、胴部３１２の少なくとも一部にねじ部が形成される。   An example of the joining member 300 is a rivet. The rivet is a part that is inserted into a holed member and caulked with a dedicated tool to be plastically deformed and joined to each other, and includes a head part 310 and a body part 312. The head 310 may be a hemispherical round head, a disc-shaped flat head, or a flat head with a flat surface side and a conical base at the surface, but here it is assumed to be a round head. Moreover, the trunk | drum 312 is formed in a cylindrical shape. Here, since the diameter of the largest portion of the head portion 310 is larger than the diameter of the trunk portion 312, when the joining member 300 is inserted from the trunk portion 312, the joining portion 300 enters by the head portion 310. It can be stopped. The joining member 300 may be a screw instead of a rivet. In that case, a thread portion is formed on at least a part of the body portion 312.

第１短フレーム１０ａは、図１（ｂ）と同様に構成されるが、底部２６には、第２接合部材３００ｂをｚ軸の負方向から挿入するための第１貫通孔３６が設けられる。また、支持部２２の底面部４０には、第１貫通孔３６に続いて、接合部材３００をｚ軸の負方向から挿入するための第２貫通孔３８が設けられる。図２（ａ）に示すように、第１長フレーム１２ａに設けられた第２貫通孔３８は、ｙ軸方向よりもｘ軸方向に長い形状に開口し、第１短フレーム１０ａに設けられた第２貫通孔３８はｘ軸方向よりもｙ軸方向に長い形状に開口する。つまり、第２貫通孔３８は、太陽電池パネル１１０の外縁部１１６に沿って長い形状に開口する。   The first short frame 10a is configured in the same manner as in FIG. 1B, but the bottom 26 is provided with a first through hole 36 for inserting the second joining member 300b from the negative direction of the z-axis. In addition, the bottom surface portion 40 of the support portion 22 is provided with a second through hole 38 for inserting the joining member 300 from the negative direction of the z axis following the first through hole 36. As shown in FIG. 2A, the second through-hole 38 provided in the first long frame 12a opens in a shape longer in the x-axis direction than in the y-axis direction, and is provided in the first short frame 10a. The second through hole 38 opens in a shape longer in the y-axis direction than in the x-axis direction. That is, the second through hole 38 opens in a long shape along the outer edge portion 116 of the solar cell panel 110.

さらに、第１短フレーム１０ａにおける第２中空部３２には、連結部材２００が配置されており、連結部材２００には、第２貫通孔３８に続いて、接合部材３００をｚ軸の負方向から挿入するための第２被挿入部２２０ｂが設けられる。図２（ｂ）に示すように、第１連結片２１０ａにおける第１被挿入部２２０ａは、ｘ−ｙ平面において円形状に開口する第１開口部２２２ａを含むとともに、第１開口部２２２ａから第１外側縁部２１６ａに向かって開口する第１切込み部２２４ａを含む。第１切込み部２２４ａは、第１外側縁部２１６ａに近づくほどｘ軸方向に広がる形状を有する。また、第２連結片２１０ｂにおける第２被挿入部２２０ｂは、ｘ−ｙ平面において円形状に開口する第２開口部２２２ｂを含むとともに、第２開口部２２２ｂから第２外側縁部２１６ｂに向かって開口する第２切込み部２２４ｂを含む。第２切込み部２２４ｂは、第２外側縁部２１６ｂに近づくほどｙ軸方向に広がる形状を有する。このような被挿入部２２０が配置される部分において連結片２１０は細くなる。図３に戻る。   Further, the connecting member 200 is disposed in the second hollow portion 32 of the first short frame 10a, and the connecting member 200 is connected to the connecting member 200 from the negative direction of the z axis following the second through hole 38. A second inserted portion 220b for insertion is provided. As shown in FIG. 2B, the first insertion portion 220a in the first connecting piece 210a includes a first opening 222a that opens in a circular shape in the xy plane, and the first opening 222a extends from the first opening 222a. 1 The 1st notch part 224a opened toward the outer side edge part 216a is included. The first notch 224a has a shape that expands in the x-axis direction as it approaches the first outer edge 216a. The second insertion portion 220b of the second connecting piece 210b includes a second opening 222b that opens in a circular shape in the xy plane, and from the second opening 222b toward the second outer edge 216b. A second notch 224b that opens is included. The second notch 224b has a shape that expands in the y-axis direction as it approaches the second outer edge 216b. The connecting piece 210 becomes thin at the portion where the inserted portion 220 is disposed. Returning to FIG.

ここで、第１貫通孔３６は、底部２６をｚ軸方向に貫通し、第２貫通孔３８は、底面部４０をｚ軸方向に貫通し、第２被挿入部２２０ｂは、連結部材２００をｚ軸方向に貫通する。また、第２貫通孔３８のｘ軸方向の幅は、胴部３１２の径よりも大きく、かつ頭部３１０の最も大きい部分の径よりも小さい。一方、第１貫通孔３６のｘ軸方向の幅は、第２貫通孔３８のｘ軸方向の幅よりも大きく、かつ頭部３１０の最も大きい部分の径よりも大きい。   Here, the first through hole 36 penetrates the bottom portion 26 in the z-axis direction, the second through hole 38 penetrates the bottom surface portion 40 in the z-axis direction, and the second inserted portion 220b passes through the connecting member 200. It penetrates in the z-axis direction. Further, the width of the second through hole 38 in the x-axis direction is larger than the diameter of the body portion 312 and smaller than the diameter of the largest portion of the head portion 310. On the other hand, the width of the first through hole 36 in the x-axis direction is larger than the width of the second through hole 38 in the x-axis direction and larger than the diameter of the largest portion of the head 310.

第２接合部材３００ｂにおいて胴部３１２がｚ軸の正方向側に向けられ、頭部３１０がｚ軸の負方向側に向けられる。そのような向きのまま、第１貫通孔３６のｚ軸の負方向側から、胴部３１２が第１貫通孔３６に挿入される。胴部３１２は、第１貫通孔３６、第２貫通孔３８、第２被挿入部２２０ｂを通過し、胴部３１２の先端は、連結部材２００を抜けて第１中空部３０に達する。一方、胴部３１２に続いて、頭部３１０も第１貫通孔３６に挿入されて通過する。しかしながら、頭部３１０の最も大きい部分の径は、第２貫通孔３８のｘ軸方向の幅よりも大きいので、頭部３１０は底面部４０で止められる。このように、頭部３１０は、底部２６よりも、ｚ軸の正方向側に配置される。そのため、第２接合部材３００ｂは、短フレーム１０の裏面側から挿入しているにもかかわらず、頭部３１０は、フレームの裏面側から出てしまわない。   In the second joining member 300b, the body portion 312 is directed to the positive direction side of the z axis, and the head portion 310 is directed to the negative direction side of the z axis. The trunk portion 312 is inserted into the first through-hole 36 from the negative direction side of the first through-hole 36 in the z-axis in such a direction. The body portion 312 passes through the first through hole 36, the second through hole 38, and the second insertion portion 220 b, and the distal end of the body portion 312 passes through the connecting member 200 and reaches the first hollow portion 30. On the other hand, following the body portion 312, the head portion 310 is also inserted into the first through hole 36 and passes therethrough. However, since the diameter of the largest portion of the head 310 is larger than the width of the second through hole 38 in the x-axis direction, the head 310 is stopped by the bottom surface portion 40. As described above, the head 310 is disposed on the positive side of the z-axis with respect to the bottom 26. Therefore, although the second joining member 300b is inserted from the back side of the short frame 10, the head 310 does not come out from the back side of the frame.

なお、図１（ａ）において、第１短フレーム１０ａと第２長フレーム１２ｂとの間、第２長フレーム１２ｂと第２短フレーム１０ｂとの間、第２短フレーム１０ｂと第１長フレーム１２ａとの間にも連結部材２００が挿入される。そのため、太陽電池モジュール１００には、４つの連結部材２００が含まれる。さらに、複数の接合部材３００のそれぞれは、短フレーム１０、長フレーム１２に設けられた第１貫通孔３６、第２貫通孔３８と、連結部材２００に設けられた被挿入部２２０に差し込まれる。そのため、複数の接合部材３００は、複数の連結部材２００のそれぞれと短フレーム１０、長フレーム１２を接合する。   In FIG. 1A, between the first short frame 10a and the second long frame 12b, between the second long frame 12b and the second short frame 10b, and between the second short frame 10b and the first long frame 12a. The connecting member 200 is also inserted between the two. Therefore, the solar cell module 100 includes four connection members 200. Further, each of the plurality of joining members 300 is inserted into the first through hole 36 and the second through hole 38 provided in the short frame 10 and the long frame 12, and the inserted portion 220 provided in the connecting member 200. Therefore, the plurality of joining members 300 join each of the plurality of connecting members 200 to the short frame 10 and the long frame 12.

図２（ｂ）は、図３のごとく、接合部材３００を挿入した後の構成を示す。ここでは、図面を明瞭にするために、第１接合部材３００ａが挿入される位置と、第２接合部材３００ｂが挿入される位置とを示し、第１接合部材３００ａと第２接合部材３００ｂの図示を省略する。   FIG. 2B shows a configuration after the joining member 300 is inserted as shown in FIG. Here, in order to clarify the drawing, a position where the first joining member 300a is inserted and a position where the second joining member 300b is inserted are shown, and the first joining member 300a and the second joining member 300b are illustrated. Is omitted.

第１接合部材３００ａは、第１連結片２１０ａと第１長フレーム１２ａとを接合する。特に、第１被挿入部２２０ａのうちの第１開口部２２２ａに第１接合部材３００ａが挿入されることによって、第１先頭部２１２ａは、ｙ軸の正方向側、つまり太陽電池パネル１１０の中央部側に変形する。その結果、第１先頭部２１２ａは、ポイントＰ１において、第１長フレーム１２ａの第２中空部３２の内壁４２であって、かつｙ軸の正方向側の内壁４２に接触する。ｙ軸の正方向側の内壁４２は、太陽電池パネル１１０の中央部側の内壁４２に相当する。また、第１被挿入部２２０ａのうちの第１開口部２２２ａに第１接合部材３００ａが挿入されることによって、第１外側縁部２１６ａのうちの第１切込み部２２４ａの近傍部分は、ｙ軸の負方向側、つまり太陽電池パネル１１０の外縁部１１６側に変形する。その結果、第１外側縁部２１６ａは、ポイントＰ２において、第１長フレーム１２ａの第２中空部３２の内壁４２であって、かつｙ軸の負方向側の内壁４２に接触する。ｙ軸の負方向側の内壁４２は、太陽電池パネル１１０の外縁部１１６側の内壁４２に相当する。   The first joining member 300a joins the first connecting piece 210a and the first long frame 12a. In particular, the first joining member 300a is inserted into the first opening 222a of the first inserted portion 220a, so that the first leading portion 212a is on the positive side of the y axis, that is, the center of the solar cell panel 110. Deforms to the part side. As a result, the first leading portion 212a is in contact with the inner wall 42 of the second hollow portion 32 of the first long frame 12a at the point P1 and on the positive side of the y axis. The inner wall 42 on the positive side of the y-axis corresponds to the inner wall 42 on the center side of the solar cell panel 110. Further, when the first joining member 300a is inserted into the first opening 222a of the first inserted portion 220a, the vicinity of the first notch 224a of the first outer edge 216a is The negative direction side, that is, the outer edge 116 side of the solar cell panel 110 is deformed. As a result, the first outer edge portion 216a is in contact with the inner wall 42 of the second hollow portion 32 of the first long frame 12a and the inner wall 42 on the negative direction side of the y-axis at the point P2. The inner wall 42 on the negative direction side of the y-axis corresponds to the inner wall 42 on the outer edge 116 side of the solar cell panel 110.

第２接合部材３００ｂは、第２連結片２１０ｂと第１短フレーム１０ａとを接合する。特に、第２被挿入部２２０ｂのうちの第２開口部２２２ｂに第２接合部材３００ｂが挿入されることによって、第２先頭部２１２ｂは、ｘ軸の負方向側、つまり太陽電池パネル１１０の中央部側に変形する。その結果、第２先頭部２１２ｂは、ポイントＰ１’において、第１短フレーム１０ａの第２中空部３２の内壁４２であって、かつｘ軸の負方向側の内壁４２に接触する。ｘ軸の負方向側の内壁４２は、太陽電池パネル１１０の中央部側の内壁４２に相当する。また、第２被挿入部２２０ｂのうちの第２開口部２２２ｂに第２接合部材３００ｂが挿入されることによって、第２外側縁部２１６ｂのうちの第２切込み部２２４ｂの近傍部分は、ｘ軸の正方向側、つまり太陽電池パネル１１０の外縁部１１６側に変形する。その結果、第２外側縁部２１６ｂは、ポイントＰ２’において、第１短フレーム１０ａの第２中空部３２の内壁４２であって、かつｘ軸の正方向側の内壁４２に接触する。ｘ軸の正方向側の内壁４２は、太陽電池パネル１１０の外縁部１１６側の内壁４２に相当する。   The second joining member 300b joins the second connecting piece 210b and the first short frame 10a. In particular, when the second bonding member 300b is inserted into the second opening 222b of the second inserted portion 220b, the second leading portion 212b is located on the negative side of the x axis, that is, the center of the solar cell panel 110. Deforms to the part side. As a result, the second leading portion 212b is in contact with the inner wall 42 of the second hollow portion 32 of the first short frame 10a and the inner wall 42 on the negative direction side of the x-axis at the point P1 '. The inner wall 42 on the negative direction side of the x-axis corresponds to the inner wall 42 on the center side of the solar cell panel 110. Further, by inserting the second joining member 300b into the second opening 222b of the second inserted portion 220b, the vicinity of the second notch 224b of the second outer edge portion 216b becomes the x-axis. The positive direction side, that is, the outer edge 116 side of the solar cell panel 110. As a result, the second outer edge portion 216b is in contact with the inner wall 42 of the second hollow portion 32 of the first short frame 10a at the point P2 'and on the inner wall 42 on the positive side of the x axis. The inner wall 42 on the positive side of the x-axis corresponds to the inner wall 42 on the outer edge 116 side of the solar cell panel 110.

これらのように、連結部材２００における連結片２１０は、被挿入部２２０への接合部材３００の挿入によって、挿入される方向とは異なった方向に変形し、第２中空部３２の対向した２つの内壁４２に接触する。その際、先頭部２１２は、太陽電池パネル１１０の中央部側の内壁４２に接触し、外側縁部２１６の一部は、太陽電池パネル１１０の外縁部１１６側の内壁４２に接触する。第２中空部３２の対向した２つの内壁４２のそれぞれに連結部材２００が接触することによって、短フレーム１０と長フレーム１２との連結に連結部材２００、接合部材３００を使用する場合であっても、短フレーム１０と長フレーム１２とのガタツキが低減される。これを実現するために、第１連結片２１０ａは、第１被挿入部２２０ａへの第１接合部材３００ａの挿入によって、挿入される方向とは異なった方向に変形可能なように構成される。また、第２連結片２１０ｂは、第２被挿入部２２０ｂへの第２接合部材３００ｂの挿入によって、挿入される方向とは異なった方向に変形可能なように構成される。   As described above, the connection piece 210 in the connection member 200 is deformed in a direction different from the insertion direction by the insertion of the joining member 300 into the insertion target portion 220, and the two opposite two portions of the second hollow portion 32 are opposed to each other. Contact the inner wall 42. At that time, the leading portion 212 contacts the inner wall 42 on the center side of the solar cell panel 110, and a part of the outer edge 216 contacts the inner wall 42 on the outer edge portion 116 side of the solar cell panel 110. Even when the connecting member 200 and the joining member 300 are used for the connection between the short frame 10 and the long frame 12 by the connection member 200 coming into contact with each of the two opposed inner walls 42 of the second hollow portion 32. The backlash between the short frame 10 and the long frame 12 is reduced. In order to realize this, the first connecting piece 210a is configured to be deformable in a direction different from the insertion direction by inserting the first joining member 300a into the first inserted portion 220a. The second connecting piece 210b is configured to be deformable in a direction different from the direction in which the second connecting piece 210b is inserted by inserting the second joining member 300b into the second inserted portion 220b.

図４（ａ）−（ｃ）は、短フレーム１０の構成を示す。ここでは、一例として、第１短フレーム１０ａの構成を示すが、第２短フレーム１０ｂも同様である。また、長フレーム１２は、長さが異なるだけで、同様の構成であってもよい。図４（ａ）は、第１短フレーム１０ａを受光面側から見た場合の構成を示す。図示のごとく、略台形の形状を有する。また、底部２６は、嵌合部２０よりもｘ軸の負方向側に突出する。   4A to 4C show the configuration of the short frame 10. Here, the configuration of the first short frame 10a is shown as an example, but the same applies to the second short frame 10b. Further, the long frame 12 may have the same configuration except for the length. FIG. 4A shows a configuration when the first short frame 10a is viewed from the light receiving surface side. As illustrated, it has a substantially trapezoidal shape. Further, the bottom portion 26 protrudes more toward the negative direction side of the x-axis than the fitting portion 20.

図４（ｂ）は、第１短フレーム１０ａを側面、さらに具体的には太陽電池モジュール１００の外側の側面から見た場合の構成を示す。ｚ軸の正方向から負方向に向かって、嵌合部２０、支持部２２、脚部２４、底部２６が順に配置される。図４（ｃ）は、第１短フレーム１０ａを裏面側から見た場合の構成を示す。これは、図４（ａ）と同様に、略台形の形状を有する。また、底部２６には、２つの第１貫通孔３６が設けられるとともに、各第１貫通孔３６の内側に第２貫通孔３８が配置される。このように、第１貫通孔３６の開口面積は、第２貫通孔３８の開口面積よりも大きい。第１貫通孔３６は、ｘ軸の正方向に開口するように凹んだ形状を有する。第２貫通孔３８は、ｘ軸方向よりもｙ軸方向に長い形状を有する。   FIG. 4B shows a configuration when the first short frame 10 a is viewed from the side surface, more specifically from the outer side surface of the solar cell module 100. The fitting part 20, the support part 22, the leg part 24, and the bottom part 26 are arrange | positioned in order toward the negative direction from the positive direction of az axis. FIG. 4C shows a configuration when the first short frame 10a is viewed from the back side. This has a substantially trapezoidal shape as in FIG. In addition, two first through holes 36 are provided in the bottom portion 26, and a second through hole 38 is disposed inside each first through hole 36. Thus, the opening area of the first through hole 36 is larger than the opening area of the second through hole 38. The first through hole 36 has a concave shape so as to open in the positive direction of the x-axis. The second through hole 38 has a shape that is longer in the y-axis direction than in the x-axis direction.

第２貫通孔３８をこのような長穴形状にする理由は次の通りである。接合部材３００の胴部３１２は、第２貫通孔３８と被挿入部２２０とを連続して貫通する。また、被挿入部２２０の開口部２２２は、前述のごとく円形状を有する。仮に、第２貫通孔３８も円形状に開口する場合、製造上の誤差によって第２貫通孔３８と開口部２２２の位置がずれてしまうと、これらを胴部３１２が貫通しにくくなったり、貫通しなくなったりする。このような状況の発生を防止するために、第２貫通孔３８は、開口部２２２よりも広い長穴形状に開口する。   The reason why the second through hole 38 has such a long hole shape is as follows. The body portion 312 of the joining member 300 passes through the second through hole 38 and the inserted portion 220 continuously. Further, the opening 222 of the inserted portion 220 has a circular shape as described above. If the second through-hole 38 is also opened in a circular shape, if the position of the second through-hole 38 and the opening 222 is shifted due to manufacturing errors, the body portion 312 will not be able to pass through it, Or not. In order to prevent the occurrence of such a situation, the second through-hole 38 opens in a long hole shape wider than the opening 222.

以下では、太陽電池モジュール１００の製造方法について説明する。まず、太陽電池モジュール１００の外縁部１１６を囲むように短フレーム１０および長フレーム１２を用意する。これに続いて、短フレーム１０および長フレーム１２の嵌合部２０に太陽電池パネル１１０の外縁部１１６を嵌合させる。また、太陽電池パネル１１０および長フレーム１２の支持部２２の第２中空部３２に連結部材２００を挿入させる。さらに、第１貫通孔３６、第２貫通孔３８に対して、ｚ軸の負方向側から接合部材３００を貫通させる。第２貫通孔３８に続いて連結部材２００の被挿入部２２０に接合部材３００を挿入させることによって、挿入される方向とは異なった方向に接合部材３００を変形させる。これによって、支持部２２の第２中空部３２における対向した２つの内壁４２に連結部材２００が接触される。   Below, the manufacturing method of the solar cell module 100 is demonstrated. First, the short frame 10 and the long frame 12 are prepared so as to surround the outer edge portion 116 of the solar cell module 100. Subsequently, the outer edge portion 116 of the solar cell panel 110 is fitted to the fitting portion 20 of the short frame 10 and the long frame 12. Further, the connecting member 200 is inserted into the second hollow portion 32 of the support portion 22 of the solar cell panel 110 and the long frame 12. Further, the joining member 300 is passed through the first through hole 36 and the second through hole 38 from the negative direction side of the z axis. The joining member 300 is deformed in a direction different from the insertion direction by inserting the joining member 300 into the inserted portion 220 of the connecting member 200 following the second through hole 38. As a result, the connecting member 200 is brought into contact with the two opposed inner walls 42 in the second hollow portion 32 of the support portion 22.

本発明の実施例によれば、被挿入部２２０への接合部材３００の挿入によって、連結部材２００が変形し、第２中空部３２の対向した２つの内壁４２に接触するので、短フレーム１０および長フレーム１２の中において連結部材２００をずれにくくできる。また、短フレーム１０および長フレーム１２の中において連結部材２００がずれにくくなるので、太陽電池モジュール１００において連結されたフレームのガタツキの発生を抑制できる。また、短フレーム１０および長フレーム１２の中において連結部材２００がずれにくくなるので、第２貫通孔３８を外縁部１１６に沿って長い形状に開口させることができる。また、第２貫通孔３８を外縁部１１６に沿って長い形状に開口させるので、接合部材３００の挿入を容易にできる。また、接合部材３００の挿入が容易になるので、太陽電池モジュール１００の製造を容易にできる。   According to the embodiment of the present invention, the connection member 200 is deformed by the insertion of the joining member 300 into the inserted portion 220 and comes into contact with the two opposed inner walls 42 of the second hollow portion 32. The connecting member 200 can be hardly displaced in the long frame 12. In addition, since the connecting member 200 is not easily displaced in the short frame 10 and the long frame 12, it is possible to suppress the occurrence of rattling of the frames connected in the solar cell module 100. Further, since the connecting member 200 is not easily displaced in the short frame 10 and the long frame 12, the second through hole 38 can be opened in a long shape along the outer edge portion 116. In addition, since the second through-hole 38 is opened in a long shape along the outer edge portion 116, the joining member 300 can be easily inserted. Moreover, since the joining member 300 can be easily inserted, the solar cell module 100 can be easily manufactured.

また、連結部材２００の先頭部２１２は、太陽電池パネル１１０の中央部側の内壁４２に接触するので、接触によって支持部２２に変形が生じた場合であっても目立たなくさせることができる。接触によって支持部２２に変形が生じた場合であっても目立たないので、意匠性の低下を抑制できる。また、連結部材２００の先頭部２１２と異なった部分は、太陽電池パネル１１０の外縁部１１６側の内壁４２に接触するので、連結部材２００をずれにくくできる。   In addition, since the leading portion 212 of the connecting member 200 contacts the inner wall 42 on the center portion side of the solar cell panel 110, even if the support portion 22 is deformed by the contact, it can be made inconspicuous. Even if the support portion 22 is deformed by the contact, it is not conspicuous, and the deterioration of the design can be suppressed. Moreover, since the part different from the head part 212 of the connection member 200 contacts the inner wall 42 on the outer edge part 116 side of the solar cell panel 110, the connection member 200 can be hardly displaced.

また、支持部２２、脚部２４、底部２６が順に配置されており、底部２６に第１貫通孔３６が設けられ、支持部２２に第２貫通孔３８が設けられるので、底部２６の方から支持部２２に接合部材３００を挿入できる。また、底部２６の方から支持部２２に接合部材３００が挿入されるので、接合部材３００の頭部３１０を目立たなくできる。また、接合部材３００の頭部３１０が目立たなくなるので、太陽電池モジュール１００の意匠性の低下を抑制できる。また、第２貫通孔３８は、支持部２２の長手方向に長い形状の開口５０を有するので、接合部材３００による連結を容易にできる。   Further, the support portion 22, the leg portion 24, and the bottom portion 26 are arranged in this order. The first through hole 36 is provided in the bottom portion 26, and the second through hole 38 is provided in the support portion 22. Therefore, from the bottom portion 26 side. The joining member 300 can be inserted into the support portion 22. Further, since the joining member 300 is inserted into the support portion 22 from the bottom 26, the head 310 of the joining member 300 can be made inconspicuous. Moreover, since the head part 310 of the joining member 300 becomes inconspicuous, the fall of the design property of the solar cell module 100 can be suppressed. In addition, since the second through hole 38 has the opening 50 having a shape that is long in the longitudinal direction of the support portion 22, the connection by the joining member 300 can be facilitated.

また、第１貫通孔３６の開口面積は、第２貫通孔３８の開口面積よりも大きいので、接合部材３００の頭部３１０を第１貫通孔３６だけ通り抜けさせ、第２貫通孔３８を通り抜けさせなくできる。また、接合部材３００の頭部３１０が第１貫通孔３６だけ通り抜け、第２貫通孔３８を通り抜けないので、底部２６の裏面側から頭部３１０を出なくできる。また、底部２６の裏面側から頭部３１０が出なくなるので、架台への乗り上げを防止できる。また、被挿入部２２０が配置される部分において連結片２１０が細くなるので、接合部材３００の挿入による変形を容易にできる。   Further, since the opening area of the first through hole 36 is larger than the opening area of the second through hole 38, the head 310 of the joining member 300 passes through only the first through hole 36 and passes through the second through hole 38. It can be lost. Further, since the head portion 310 of the joining member 300 passes only through the first through hole 36 and does not pass through the second through hole 38, the head portion 310 can be prevented from exiting from the back side of the bottom portion 26. Moreover, since the head 310 does not come out from the back surface side of the bottom part 26, the boarding on a mount can be prevented. Moreover, since the connecting piece 210 becomes thin at the portion where the inserted portion 220 is disposed, the deformation due to the insertion of the joining member 300 can be facilitated.
