（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、太陽電池モジュールにおける太陽電池パネルの各辺に配置されるフレームに関する。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、連結部材とフレームとを固定するために、接合部材が使用される。前述のごとく、フレームの外面から接合部材を挿入した場合、接合部材の頭部が外面に露出することによって、太陽電池モジュールの意匠性が低下する。このような意匠性の低下を抑制するために、フレームの下面から接合部材を挿入すると、接合部材の頭部が外面に露出することが防止される。しかしながら、接合部材の頭部がフレームの下面から出てしまうので、太陽電池モジュールを架台に固定した場合に、接合部材の頭部が架台に乗り上げ、架台固定が不安定になる。そのため、フレームの下面から接合部材を挿入することは、一般的に採用されていない。 Example 1
Before describing the present invention in detail, an outline will be described. Example 1 of this invention is related with the flame | frame arrange | positioned at each edge | side of the solar cell panel in a solar cell module. The frame has a hollow structure, and a connecting member for connecting adjacent frames is inserted into the frame. In addition, a joining member is used to fix the connecting member and the frame. As described above, when the joining member is inserted from the outer surface of the frame, the design of the solar cell module is deteriorated by exposing the head of the joining member to the outer surface. When the joining member is inserted from the lower surface of the frame in order to suppress such deterioration in designability, the head of the joining member is prevented from being exposed to the outer surface. However, since the head of the joining member comes out of the lower surface of the frame, when the solar cell module is fixed to the gantry, the head of the joining member rides on the gantry and the gantry fixing becomes unstable. For this reason, inserting a joining member from the lower surface of the frame is not generally employed.

太陽電池モジュールの意匠性の低下を抑制しながら、架台固定の安定性を維持するために、本実施例に係るフレームでは、中空構造を有した支持部から下方に延びる脚部が設けられるとともに、脚部の下方に底部が配置される。ここで、フレームは、底部によって支えられる。このような支持部、脚部、底部によって、外面から凹んだ溝構造が形成される。さらに、底部と支持部とを貫通するような貫通孔を設け、接合部材を下方から貫通孔に挿入させる。その際、接合部材の頭部は支持部に固定されるので、接合部材の頭部が底部の下面から出ない。このようにフレームの貫通孔、連結部材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、接合部材による連結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。   In order to maintain the stability of the gantry fixing while suppressing the deterioration of the design of the solar cell module, the frame according to the present embodiment is provided with legs that extend downward from the support portion having a hollow structure, A bottom portion is disposed below the leg portion. Here, the frame is supported by the bottom. Such a support part, leg part, and bottom part form a groove structure that is recessed from the outer surface. Furthermore, a through-hole that penetrates the bottom portion and the support portion is provided, and the joining member is inserted into the through-hole from below. At this time, since the head of the joining member is fixed to the support portion, the head of the joining member does not come out from the lower surface of the bottom. In this way, when connecting the frames by inserting the joining members into the through holes and the connecting members of the frame, the through holes of the frame are used in order to facilitate the connection by the joining members while taking into account processing tolerance restrictions. It is formed in a long hole shape.

しかしながら、長穴形状にすることによって、接合部材による連結の強度が弱くなり、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、本実施例に係るフレームでは、長穴形状に形成された貫通孔の内部に、複数の突起部が設けられる。これにより、貫通孔に挿入された接合部材が複数の突起部によって固定されることによって、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 using the elongated hole shape, the strength of the connection 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 frame according to the present embodiment is provided with a plurality of protrusions inside the through hole formed in the shape of a long hole. As a result, the joining member inserted into the through hole is fixed by the plurality of protrusions, thereby suppressing the occurrence of rattling. 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 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）において、第１短フレーム１０ａと第１長フレーム１２ａとが隣接する部分を拡大した図であり、受光面側から見た場合の構成を示す。ｙ軸方向に延びた第１短フレーム１０ａと、ｘ軸方向に延びた第１長フレーム１２ａとは、略直角につなぎ合わされる。また、それらの内部に連結部材２００を挿入させることによって、第１短フレーム１０ａと第１長フレーム１２ａとが連結される。連結部材２００は、太陽電池モジュール１００の受光面側および裏面側から見えないので、点線で示される。   FIG. 1B is an enlarged view of a portion where the first short frame 10a and the first long frame 12a are adjacent to each other in FIG. 1A, and shows 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. Since the connecting member 200 is not visible from the light receiving surface side and the back surface side of the solar cell module 100, it is indicated by a dotted line.

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。なお、連結部材２００において、第１連結片２１０ａと第２連結片２１０ｂは一体的に形成される。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、第２連結片２１０ｂは、第１短フレーム１０ａの内部に挿入される。   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. In the connection member 200, the first connection piece 210a and the second connection piece 210b are integrally formed. With such a configuration, the first connecting piece 210a is inserted into the first long frame 12a, and the second connecting piece 210b is inserted into the first short frame 10a.

その際、第１長フレーム１２ａへの第１連結片２１０ａの挿入を容易にするために、第１連結片２１０ａのｘ軸の負方向側には、第１連結片端部２１２ａが配置される。ここで、第１連結片端部２１２ａは、鋭角をなす形状に形成される。また、第２連結片２１０ｂにおいても、同様に第２連結片端部２１２ｂが形成される。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。さらに、第１連結片２１０ａには、円形状に開口した第１被挿入部２２０ａが設けられ、第２連結片２１０ｂには、円形状に開口した第２被挿入部２２０ｂが設けられる。これらの詳細については後述する。   At that time, in order to facilitate the insertion of the first connecting piece 210a into the first long frame 12a, the first connecting piece end portion 212a is disposed on the negative side of the first connecting piece 210a in the x-axis direction. Here, the 1st connection piece end part 212a is formed in the shape which makes an acute angle. Similarly, the second connection piece end portion 212b is formed in the second connection piece 210b. When the connecting piece 210 is inserted into the frame, the connecting member 200 connects adjacent frames. Further, the first connecting piece 210a is provided with a first inserted portion 220a that is opened in a circular shape, and the second connecting piece 210b is provided with a second inserted portion 220b that is opened in a circular shape. Details of these will be described later.

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。   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, between the second short frame 10b and the first long frame 12a. The connecting member 200 is also inserted therebetween. Therefore, the solar cell module 100 includes four connection members 200.

図２（ａ）−（ｂ）は、太陽電池モジュール１００の構成を示す断面図である。図２（ａ）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、外縁部１１６とされる。   2A to 2B are cross-sectional views illustrating the configuration of the solar cell module 100. FIG. 2A 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. 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 is an outer edge 116.

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. The support portion 22 includes a top surface portion 28 and a first hollow portion. 30, a second hollow portion 32, a first partition piece 34 a collectively referred to as a partition piece 34, a second partition piece 34 b, and a bottom surface portion 40. Here, the fitting part 20, the support part 22, the leg part 24, and the bottom part 26 are integrally formed.

嵌合部２０は、後述の支持部２２のｚ軸の正方向側に配置され、支持部２２の天面部２８と組み合わされることによって、ｘ軸の負方向側に凹んだ断面を有する。このような形状によって、嵌合部２０には、ｘ軸の負方向側から太陽電池パネル１１０の外縁部１１６が嵌め込まれる。なお、嵌合部２０および天面部２８と、太陽電池パネル１１０とは、ブチル系の封止材またはシリコン系の接着剤などによって固定される。   The fitting portion 20 is disposed on the positive side of the z-axis of the support portion 22 described later, and has a cross section that is recessed on the negative direction side of the x-axis when combined with the top surface portion 28 of the support portion 22. With such a shape, the outer edge portion 116 of the solar cell panel 110 is fitted into the fitting portion 20 from the negative direction side of the x axis. In addition, the fitting part 20 and the top | upper surface part 28, and the solar cell panel 110 are fixed with a butyl-type sealing material or a silicon-type adhesive agent.

支持部２２は、嵌合部２０をｚ軸の負方向側から支持する。支持部２２のｚ軸の正方向側には、嵌合部２０と対向するように天面部２８が配置される。また、支持部２２は、略矩形状の断面を有するとともに、中空構造の内壁に第１仕切片３４ａと第２仕切片３４ｂとを対向して備える。第１仕切片３４ａと第２仕切片３４ｂとによって、中空構造が第１中空部３０と第２中空部３２とに分けられる。支持部２２のｚ軸の負方向側の底面部４０において、ｘ軸の負方向側から、ｚ軸の負方向に向かって脚部２４が備えられる。なお、脚部２４は、底面部４０のどの部分に接続されてもよい。脚部２４のｚ軸の負方向側には、底部２６が配置される。底部２６は、ｘ軸方向に延びた断面を有し、底部２６をｚ軸の負方向側から支持する。   The support part 22 supports the fitting part 20 from the negative direction side of the z-axis. 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 each other on the inner wall of the 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 bottom portion 26 from the negative direction side of the z-axis.

図２（ｂ）は、図１（ｂ）における太陽電池モジュール１００のｘ軸、具体的にはＢ−Ｂ’線に沿った断面図である。これは、連結部材２００に第２被挿入部２２０ｂが形成された部分を含む断面図であるといえる。なお、太陽電池パネル１１０は省略される。図２（ｂ）では、接合部材３００が示される。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。なお、胴部３１２には、ねじ部が形成されない。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。   2B is a cross-sectional view of the solar cell module 100 in FIG. 1B along the x-axis, specifically the B-B ′ line. This can be said to be a cross-sectional view including a portion where the second inserted portion 220b is formed in the connecting member 200. Note that the solar cell panel 110 is omitted. In FIG.2 (b), the joining member 300 is shown. 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. It should be noted that no thread portion is formed on the body portion 312. 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２（ａ）と同様に構成されるが、底部２６には、接合部材３００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。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。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、第２被挿入部２２０ｂのｘ軸方向の幅と同等であり、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。   The first short frame 10a is configured in the same manner as in FIG. 2A, but the bottom portion 26 is provided with a first through hole 36 for inserting the joining member 300 from the negative direction of the z-axis. Further, 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. 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. 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 equal to the width of the second inserted portion 220b in the x-axis direction, which is larger than the diameter of the body portion 312 and the largest portion of the head portion 310. Smaller than the diameter. 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.

接合部材３００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２貫通孔３８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、接合部材３００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 joining member 300, the body 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 second through hole 38 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 joining member 300 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.

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。   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３（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３（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。   3A to 3C 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. 3A 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３（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３（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３（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. 3B 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. 3C 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は、前述のごとく円形状に開口する。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と被挿入部２２０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、被挿入部２２０よりも広い長穴形状に開口する。しかしながら、このような第２貫通孔３８の長穴形状によって、第２貫通孔３８に挿入された頭部３１０はｙ軸方向に移動しやすくなり、ガタツキ発生の原因となりうる。これを抑制するための第２貫通孔３８の構成をさらに詳細に説明するために、図４（ａ）−（ｃ）を使用する。   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 inserted portion 220 opens in 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 inserted portion 220 is shifted due to manufacturing errors, the body portion 312 is less likely to pass through, It will not penetrate. In order to prevent the occurrence of such a situation, the second through hole 38 opens in a long hole shape wider than the insertion target portion 220. However, such a long hole shape of the second through hole 38 makes it easier for the head 310 inserted into the second through hole 38 to move in the y-axis direction, which may cause rattling. FIGS. 4A to 4C are used to describe the configuration of the second through hole 38 for suppressing this in more detail.

図４（ａ）−（ｃ）は、第２貫通孔３８の構成を示す。図４（ａ）は、図３（ｃ）に示された第２貫通孔３８を拡大した図に相当する。第２貫通孔３８は、前述のごとく、ｘ軸方向よりもｙ軸方向に長い形状、つまり、支持部２２の長手方向に長い形状の開口５０を有する。開口５０は、ｙ軸方向に延びる第１縁部５２ａと第２縁部５２ｂ、ｘ軸方向に延びる第３縁部５２ｃと第４縁部５２ｄとによって囲まれる。第１縁部５２ａ、第２縁部５２ｂ、第３縁部５２ｃ、第４縁部５２ｄは縁部５２と総称される。ここで、第１縁部５２ａは、第２縁部５２ｂよりもｘ軸の負方向側に配置され、第３縁部５２ｃは、第４縁部５２ｄよりもｙ軸の正方向側に配置される。   4A to 4C show the configuration of the second through hole 38. FIG. FIG. 4A corresponds to an enlarged view of the second through hole 38 shown in FIG. As described above, the second through hole 38 has an opening 50 that is longer in the y-axis direction than in the x-axis direction, that is, longer in the longitudinal direction of the support portion 22. The opening 50 is surrounded by a first edge 52a and a second edge 52b extending in the y-axis direction, and a third edge 52c and a fourth edge 52d extending in the x-axis direction. The first edge 52a, the second edge 52b, the third edge 52c, and the fourth edge 52d are collectively referred to as the edge 52. Here, the first edge portion 52a is disposed on the negative side of the x axis with respect to the second edge portion 52b, and the third edge portion 52c is disposed on the positive direction side of the y axis with respect to the fourth edge portion 52d. The

また、図４（ａ）には、比較のために被挿入部２２０も示される。被挿入部２２０は、円形状に開口し、開口５０内に配置される。第２貫通孔３８のｘ軸方向の幅は、第２被挿入部２２０ｂのｘ軸方向の幅と同等であるが、第２貫通孔３８のｙ軸方向の幅は、第２被挿入部２２０ｂのｙ軸方向の幅よりも大きい。   FIG. 4A also shows the inserted portion 220 for comparison. The inserted portion 220 opens in a circular shape and is disposed in the opening 50. The width of the second through hole 38 in the x-axis direction is equal to the width of the second inserted portion 220b in the x-axis direction, but the width of the second through hole 38 in the y-axis direction is equal to the second inserted portion 220b. Greater than the width in the y-axis direction.

第２貫通孔３８には、複数の突起部５４が備えられる。具体的に説明すると、互いに対向した第１縁部５２ａと第２縁部５２ｂに、ｙ軸を対称軸として、複数の突起部５４は対称的に配置される。複数の突起部５４のそれぞれは、縁部５２から開口５０に向かって突出する。特に、各突起部５４の先端部は、鋭角をなす形状を有する。このような複数の突起部５４によって、開口５０内に挿入された胴部３１２（図示せず）におけるｙ軸方向への移動が抑制される。   The second through hole 38 is provided with a plurality of protrusions 54. More specifically, the plurality of projecting portions 54 are symmetrically disposed on the first edge portion 52a and the second edge portion 52b facing each other, with the y axis as the axis of symmetry. Each of the plurality of protrusions 54 protrudes from the edge 52 toward the opening 50. In particular, the tip of each projection 54 has an acute angle. By such a plurality of protrusions 54, movement in the y-axis direction in the body 312 (not shown) inserted into the opening 50 is suppressed.

図４（ｂ）は、第２貫通孔３８の別の構成を示す。開口５０、縁部５２は、図４（ａ）と同様に構成される。また、複数の突起部５４のそれぞれは、縁部５２から縁部５２に向かって突出する。一方、図４（ｂ）において、互いに対向した第１縁部５２ａと第２縁部５２ｂに、ｙ軸を対称軸として、複数の突起部５４は非対称的に配置される。図４（ｃ）は、第２貫通孔３８のさらに別の構成を示す。開口５０、縁部５２は、図４（ａ）と同様に構成される。また、互いに対向した第１縁部５２ａと第２縁部５２ｂに、ｙ軸を対称軸として、複数の突起部５４は対称的に配置される。一方、図４（ｃ）において、各突起部５４の先端部は、曲線をなす形状を有する。   FIG. 4B shows another configuration of the second through hole 38. The opening 50 and the edge 52 are configured in the same manner as in FIG. Further, each of the plurality of protrusions 54 protrudes from the edge 52 toward the edge 52. On the other hand, in FIG. 4B, the plurality of protrusions 54 are asymmetrically arranged on the first edge 52a and the second edge 52b facing each other with the y axis as the axis of symmetry. FIG. 4C shows still another configuration of the second through hole 38. The opening 50 and the edge 52 are configured in the same manner as in FIG. In addition, the plurality of protrusions 54 are symmetrically disposed on the first edge 52a and the second edge 52b facing each other with the y axis as the axis of symmetry. On the other hand, in FIG.4 (c), the front-end | tip part of each projection part 54 has a shape which makes a curve.

本発明の実施例によれば、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。また、開口５０の縁部５２から開口５０に向かって突出する複数の突起部５４が備えられるので、接合部材３００による連結を容易にしながら、連結した短フレーム１０、長フレーム１２におけるガタツキの発生を抑制できる。   According to the embodiment of the present invention, the support portion 22, the leg portion 24, and the bottom portion 26 are arranged in 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, the joining member 300 can be inserted into the support portion 22 from the bottom portion 26. 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. In addition, since a plurality of protrusions 54 projecting from the edge 52 of the opening 50 toward the opening 50 are provided, rattling of the connected short frame 10 and long frame 12 can be prevented while facilitating connection by the joining member 300. Can be suppressed.

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。   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.

また、突起部５４の先端部は、鋭角をなす形状を有するので、開口５０内を接合部材３００がずれることを防止できる。また、突起部５４の先端部は、曲線をなす形状を有するので、開口５０内への接合部材３００の挿入を容易にしながら、開口５０内を接合部材３００がずれることを防止できる。また、複数の突起部５４は、対向した縁部５２に対称的に配置されるので、開口５０内を接合部材３００がずれることを防止できる。また、複数の突起部５４は、対向した縁部５２に非対称的に配置されるので、開口５０内を接合部材３００がずれることを防止できる。また、意匠性の低下を抑制した太陽電池モジュール１００を提供できる。   In addition, since the tip end portion of the protrusion 54 has an acute angle shape, the bonding member 300 can be prevented from being displaced in the opening 50. In addition, since the distal end portion of the protrusion 54 has a curved shape, the joining member 300 can be prevented from being displaced in the opening 50 while facilitating the insertion of the joining member 300 into the opening 50. Further, since the plurality of projecting portions 54 are symmetrically disposed on the opposed edge portions 52, it is possible to prevent the joining member 300 from shifting in the opening 50. Further, since the plurality of protrusions 54 are disposed asymmetrically at the opposed edge portions 52, it is possible to prevent the joining member 300 from being displaced within the opening 50. Moreover, the solar cell module 100 which suppressed the designable fall can be provided.
