（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の中空内部に挿入される。連結部材は、コーナージョイント、コーナーピース、コーナーキーとも呼ばれ、例えば、太陽電池パネル側を内側として内側に屈曲したＬ字型形状を有する。連結部材をフレームに挿入した状態において、連結部材の内側縁部に重なるフレームの内側壁部をカシメ治具によって加圧することによって、連結部材とフレームが固定される。これまで、連結部材とフレームとの固定を強力にするために、連結部材の内側縁部には複数の凸部と凹部からなる爪が形成されており、この複数の爪と、カシメ治具の凸部が噛み合わされることによってフレームを変形させていた。しかしながら、前述のごとく、カシメ治具の凸部に対して、連結部材の複数の爪における凸部と凹部があたるので、カシメの深さが浅くなってしまう。カシメの深さが浅くなってしまうと、連結部材とフレームとの固定が十分強力にならない。 Example 1
Before describing the present invention in detail, an outline will be described. Example 1 of this invention is related with the 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 hollow inside of the frame. The connecting member is also called a corner joint, a corner piece, or a corner key, and has, for example, an L-shape that is bent inward with the solar cell panel side as an inner side. In a state where the connecting member is inserted into the frame, the connecting member and the frame are fixed by pressurizing the inner wall portion of the frame overlapping the inner edge of the connecting member with a caulking jig. Until now, in order to strengthen the fixing of the connecting member and the frame, the inner edge of the connecting member has been formed with a plurality of projections and recesses, and the plurality of claws and the caulking jig The frame was deformed by engaging the projections. However, as described above, since the convex portions and the concave portions of the plurality of claws of the connecting member hit the convex portion of the caulking jig, the caulking depth becomes shallow. When the caulking depth becomes shallow, the connection member and the frame are not sufficiently fixed.

本実施例では、連結部材とフレームとの固定を強力にするために、連結部材の内側縁部の形状をカシメ治具の形状に整合させる。つまり、連結部材において、カシメ治具の凹部に対応した位置に内側縁部の凸部が配置され、カシメ治具の凸部に対応した位置に内側縁部の凹部が配置される。これにより、連結部材の内側縁部の凹部だけがカシメ治具の凸部にあたるので、カシメの深さが深くなり、連結部材とフレームとの固定が強力になる。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。 In the present embodiment, the shape of the inner edge of the connecting member is matched with the shape of the crimping jig in order to strengthen the fixing between the connecting member and the frame. That is, in the connecting member, the convex portion of the inner edge portion is arranged at a position corresponding to the concave portion of the caulking jig, and the concave portion of the inner edge portion is arranged at a position corresponding to the convex portion of the caulking jig. Thereby, since only the recessed part of the inner edge part of a connection member hits the convex part of a crimping jig | tool, the depth of crimping becomes deep and fixation with a connection member and a flame | frame becomes strong. 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、太陽電池モジュール１００の構造を示す。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造を示す。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。 1A to 1B show the structure of the solar cell module 100.

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」と呼び、ｚ軸の負方向側を「裏面側」と呼ぶ。 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またはガラス基板が配置される。また、透光性基板と裏面保護部材との間には、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、等が使用される。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 or a glass substrate 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 surface protection member, 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. , Etc. are 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軸方向の両端の２辺には、ｙ軸方向に延びる短フレーム１０が取り付けられ、太陽電池パネル１１０のｙ軸方向の両端の２辺には、ｘ軸方向に延びる長フレーム１２が取り付けられる。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。短フレーム１０と長フレーム１２は、延びる方向を横切る方向において同一形状の断面を有してもよい。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形成される。 The short frames 10 extending in the y-axis direction are attached to the two sides at both ends in the x-axis direction of the solar cell panel 110, and the length extending in the x-axis direction at the two sides at both ends in the y-axis direction of the solar cell panel 110. A frame 12 is attached. 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. The short frame 10 and the long frame 12 are formed by extrusion molding. The short frame 10 and the long frame 12 may have the same cross section in the 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、端子ボックスには、２本のケーブルのそれぞれの一端側が接続され、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. In addition, one end side of each of the two cables is connected to the terminal box, and a connector is connected to the other end side 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造を示す。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、隣接した第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 structure 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 adjacent 1st short frame 10a and the 1st long frame 12a are connected by inserting the connection member 200 in those inside. 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。このような構造によって、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 structure, the first connection piece 210a is inserted into the first long frame 12a, and the second connection 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。なお、連結部材２００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. Details of the connecting member 200 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は、長フレーム１２の構造を示す断面図である。これは、図１（ｂ）における太陽電池モジュール１００のｙ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ｙ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ｙ軸の正方向側端と、ｙ軸の負方向側端のそれぞれは、外縁部１１６とされる。 FIG. 2 is a cross-sectional view showing the structure of the long frame 12. This is a cross-sectional view of the solar cell module 100 in FIG. 1B along the y-axis, specifically the A-A ′ line. The solar cell panel 110 has a shape that is longer in the y-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 y axis side and the negative end on the y axis side of the solar cell panel 110 is an outer edge portion 116.

第１長フレーム１２ａと第２長フレーム１２ｂとは、左右対称ではあるが、同様の構造を有するので、以下では、第１長フレーム１２ａをもとに説明する。なお、図示しない短フレーム１０も、長フレーム１２と同様の構造を有してもよい。第１長フレーム１２ａ、第２長フレーム１２ｂを総称する長フレーム１２は、嵌合部２０、支持部２２、鍔部２４を含み、支持部２２は、天面部２８、中空部３０、底面部３２を含む。ここで、嵌合部２０、支持部２２、鍔部２４は、一体的に形成される。 The first long frame 12a and the second long frame 12b are bilaterally symmetric but have the same structure, and therefore will be described below based on the first long frame 12a. Note that the short frame 10 (not shown) may have the same structure as the long frame 12. The long frame 12 that collectively refers to the first long frame 12a and the second long frame 12b includes a fitting portion 20, a support portion 22, and a flange portion 24. The support portion 22 includes a top surface portion 28, a hollow portion 30, and a bottom surface portion 32. including. Here, the fitting part 20, the support part 22, and the collar part 24 are integrally formed.

嵌合部２０は、後述の支持部２２の受光面側に配置され、支持部２２の天面部２８と組み合わされることによって、ｙ軸の負方向側に窪んだ断面を有する。このような形状によって、嵌合部２０には、ｙ軸の正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ー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 light receiving surface side of the support portion 22 described later, and has a cross section that is recessed toward the negative direction side of the y-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 positive direction side of the y-axis. In addition, the fitting part 20 and the top | upper surface part 28, and the solar cell panel 110 are fixed by the butyl-type sealing material or the silicone type adhesive agent.

支持部２２は、嵌合部２０を裏面側から支持する。支持部２２の受光面側には、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、断面形状において中空部３０が配置される。支持部２２の裏面側には底面部３２が配置される。つまり、天面部２８と底面部３２は、中空部３０を挟んで反対側に配置される。支持部２２および中空部３０は、ｙ軸方向よりもｚ軸方向に長い形状を有する。これは、太陽電池モジュール１００の耐荷重性能の向上および輸送時の２段積みに対する要求を満たすためである。中空部３０には、第１連結片２１０ａが挿入される。第１連結片２１０ａの形状も、中空部３０と同様に、ｙ軸方向よりもｚ軸方向に長くされる。底面部３２のｙ軸の正方向側には、さらにｙ軸の正方向側に向かって延びる鍔部２４が配置される。 The support part 22 supports the fitting part 20 from the back side. A top surface portion 28 is disposed on the light receiving surface side of the support portion 22 so as to face the fitting portion 20. The support portion 22 has a substantially rectangular cross section, and the hollow portion 30 is disposed in the cross-sectional shape. A bottom surface portion 32 is disposed on the back surface side of the support portion 22. That is, the top surface portion 28 and the bottom surface portion 32 are disposed on the opposite sides with the hollow portion 30 interposed therebetween. The support part 22 and the hollow part 30 have a shape that is longer in the z-axis direction than in the y-axis direction. This is to satisfy the demand for improvement in load bearing performance of the solar cell module 100 and two-stage stacking during transportation. The first connecting piece 210 a is inserted into the hollow portion 30. Similarly to the hollow portion 30, the shape of the first connecting piece 210a is also longer in the z-axis direction than in the y-axis direction. On the positive direction side of the y-axis of the bottom surface portion 32, a flange 24 that extends further toward the positive direction side of the y-axis is disposed.

The surface is omitted. As described above, the first short frame 10 a and the second long frame 12 b are connected in an L shape by the connecting member 200. Here, the solar cell panel 110 is disposed on the inner side of the L-shaped bend, that is, on the lower side surrounded by the first short frame 10a and the second long frame 12b in FIGS. This may be referred to as “solar cell panel 110 side” or “inside”. On the other hand, the inner side opposite to the first short frame 10a and the second long frame 12b in FIGS. 3A to 3B may be referred to as “outer side”.

Here, the space surrounded by the first inner wall portion 50a and the first outer wall portion 52a and the space surrounded by the second inner wall portion 50b and the second outer wall portion 52b are the hollow portion 30 described above. It corresponds to.

前述のごとく、連結部材２００の第１連結片２１０ａは、第１長フレーム１２ａの中空部３０に挿入され、連結部材２００の第２連結片２１０ｂは、第１短フレーム１０ａの中空部３０に挿入される。ここで、第２連結片２１０ｂは、第１連結片２１０ａの一端から太陽電池パネル１１０側を内側として略直角に内側に屈曲する。このような第１連結片２１０ａの太陽電池パネル１１０側には第１内側縁部２２０ａが配置され、第１連結片２１０ａにおける第１内側縁部２２０ａの反対側には第１外側縁部２２２ａが配置される。第２連結片２１０ｂの太陽電池パネル１１０側には第２内側縁部２２０ｂが配置され、第２連結片２１０ｂにおける第２内側縁部２２０ｂの反対側には第２外側縁部２２２ｂが配置される。ここで、第１内側縁部２２０ａ、第２内側縁部２２０ｂは、内側縁部２２０と総称され、第１外側縁部２２２ａ、第２外側縁部２２２ｂは、外側縁部２２２と総称される。 As described above, the first connecting piece 210a of the connecting member 200 is inserted into the hollow portion 30 of the first long frame 12a, and the second connecting piece 210b of the connecting member 200 is inserted into the hollow portion 30 of the first short frame 10a. Is done. Here, the second connection piece 210b bends inward at a substantially right angle from one end of the first connection piece 210a with the solar cell panel 110 side as the inside. A first inner edge 220a is disposed on the solar cell panel 110 side of the first connection piece 210a, and a first outer edge 222a is disposed on the opposite side of the first connection piece 210a to the first inner edge 220a. Be placed. A second inner edge 220b is disposed on the solar cell panel 110 side of the second connection piece 210b, and a second outer edge 222b is disposed on the opposite side of the second connection piece 210b to the second inner edge 220b. . Here, the first inner edge 220a and the second inner edge 220b are collectively referred to as the inner edge 220, and the first outer edge 222a and the second outer edge 222b are collectively referred to as the outer edge 222.

第１連結片２１０ａの第１内側縁部２２０ａには、第２連結片２１０ｂ側端から順番に、第１凹部２３２ａ、凸部２３０、第２凹部２３２ｂが配置される。第１凹部２３２ａ、凸部２３０、第２凹部２３２ｂは、カシメ治具３００の第１凸部３１２ａ、凹部３１０、第２凸部３１２ｂにそれぞれ整合するように配置される。このような第１内側縁部２２０ａは、第１内側縁部２２０ａに重なる第１長フレーム１２ａの第１内側壁部５０ａを加圧するためのカシメ治具３００の形状に整合される形状を有するといえる。なお、第１凹部２３２ａ、第２凹部２３２ｂは、凹部２３２と総称される。一方、第２連結片２１０ｂの第２内側縁部２２０ｂも第１内側縁部２２０ａと同様の構造を有する。 A first concave portion 232a, a convex portion 230, and a second concave portion 232b are disposed on the first inner edge 220a of the first connecting piece 210a in order from the end on the second connecting piece 210b side. The first concave portion 232a, the convex portion 230, and the second concave portion 232b are disposed so as to be aligned with the first convex portion 312a, the concave portion 310, and the second convex portion 312b of the caulking jig 300, respectively. The first inner edge 220a has a shape that matches the shape of the crimping jig 300 for pressing the first inner wall 50a of the first long frame 12a that overlaps the first inner edge 220a. I can say that. In addition, the 1st recessed part 232a and the 2nd recessed part 232b are named the recessed part 232 generically. On the other hand, the second inner edge 220b of the second connecting piece 210b also has the same structure as the first inner edge 220a.

図３（ｂ）は、カシメ治具３００による圧力を加えている場合の構造を示す。カシメ治具３００は、第１長フレーム１２ａの第１内側壁部５０ａと、第２短フレーム１０ｂの第２内側壁部５０ｂとを同時に加圧する。これにより、第１内側縁部２２０ａと第２内側縁部２２０ｂの第１凹部２３２ａ、凸部２３０、第２凹部２３２ｂは、カシメ治具３００の第１凸部３１２ａ、凹部３１０、第２凸部３１２ｂに噛み合わされる。その結果、内側壁部５０には、第１内側縁部２２０ａと第２内側縁部２２０ｂの第１凹部２３２ａ、凸部２３０、第２凹部２３２ｂの形状にあった凸凹形状が形成される。特に、内側壁部５０において、第１凹部２３２ａに接する位置に第１カシメ部５４ａが形成され、第２凹部２３２ｂに接する位置に第２カシメ部５４ｂが形成される。第１カシメ部５４ａ、第２カシメ部５４ｂは、カシメ部５４と総称される。つまり、連結部材２００には、カシメ部５４の幅とほぼ同サイズの幅を有する凹部２３２が含まれ、カシメ部５４の中心と凹部２３２の中心とがほぼ一致する。これによりカシメの深さが深くなる。 FIG. 3B shows the structure when pressure is applied by the crimping jig 300. The crimping jig 300 simultaneously pressurizes the first inner wall portion 50a of the first long frame 12a and the second inner wall portion 50b of the second short frame 10b. Accordingly, the first concave portion 232a, the convex portion 230, and the second concave portion 232b of the first inner edge portion 220a and the second inner edge portion 220b are the first convex portion 312a, the concave portion 310, and the second convex portion of the caulking jig 300. 312b is engaged. As a result, the inner wall portion 50 is formed with a concave / convex shape corresponding to the shapes of the first concave portion 232a, the convex portion 230, and the second concave portion 232b of the first inner edge portion 220a and the second inner edge portion 220b. In particular, in the inner wall portion 50, the first crimping portion 54a is formed at a position in contact with the first recess 232a, and the second crimping portion 54b is formed at a position in contact with the second recess 232b. The first caulking portion 54a and the second caulking portion 54b are collectively referred to as the caulking portion 54. That is, the connecting member 200 includes a recess 232 having a width that is approximately the same as the width of the crimping portion 54, and the center of the crimping portion 54 and the center of the recess 232 substantially coincide with each other. This increases the caulking depth.

図２に示したように、少なくとも太陽電池モジュール１００の耐荷重性能を向上させるために、支持部２２および中空部３０は、ｙ軸方向よりもｚ軸方向に長い形状を有し、これに合わせて、第１連結片２１０ａもｚ軸方向に長くなる形状を有する。図２において、第１内側壁部５０ａの高さは「Ａ」と示され、支持部２２の幅は「Ｂ」と示される。ここでは、例えば、Ａ：Ｂが「４：１」であるとされる。一方、支持部２２を高くすると、支持部２２が回転しやすくなり、短フレーム１０および長フレーム１２が曲がりやすくなる。このような支持部２２の回転を抑制するために、連結部材２００の高さを高くし、かつ、カシメ部５４は、第１内側壁部５０ａの上端部から２５％の範囲内と、第１内側壁部５０ａの下端部から２５％の範囲内とに配置される。 As shown in FIG. 2, in order to improve at least the load bearing performance of the solar cell module 100, the support portion 22 and the hollow portion 30 have a shape that is longer in the z-axis direction than in the y-axis direction. The first connecting piece 210a also has a shape that is elongated in the z-axis direction. In FIG. 2, the height of the first inner wall portion 50 a is indicated as “A”, and the width of the support portion 22 is indicated as “B”. Here, for example, A: B is assumed to be “4: 1”. On the other hand, when the support portion 22 is raised, the support portion 22 is likely to rotate, and the short frame 10 and the long frame 12 are easily bent. In order to suppress such rotation of the support portion 22, the height of the connecting member 200 is increased, and the caulking portion 54 is within a range of 25% from the upper end portion of the first inner wall portion 50a, and the first It arrange | positions in the range of 25% from the lower end part of the inner wall part 50a.

つまり、第１内側壁部５０ａの上端部からの範囲「Ｃ」内と、第１内側壁部５０ａの下端部からの範囲「Ｄ」内とに、２つのカシメ部５４がｚ軸方向に並べられるが、Ａ：Ｂ＝４：１である場合に、ＣとＤはいずれも「１／４」とされる。なお、Ａ：Ｂ＝７：１である場合に、ＣとＤはいずれも「１／７」とされる。このような高さ方向の２つのカシメ部５４の距離を長くすることによって、支持部２２の回転が抑制される。図２と図３（ｂ）とを組み合わせると、８つのカシメ部５４が形成される。 That is, the two crimping portions 54 are arranged in the z-axis direction in the range “C” from the upper end portion of the first inner wall portion 50a and in the range “D” from the lower end portion of the first inner wall portion 50a. However, when A: B = 4: 1, both C and D are set to “¼”. When A: B = 7: 1, C and D are both “1/7”. By increasing the distance between the two caulking portions 54 in the height direction, the rotation of the support portion 22 is suppressed. When FIG. 2 and FIG. 3B are combined, eight caulking portions 54 are formed.

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、隣接した短フレーム１０および長フレーム１２の支持部２２の中空部３０に連結部材２００を挿入させる。さらに、隣接した短フレーム１０および長フレーム１２の内側壁部５０をカシメ治具３００によって加圧する。ここで、連結部材２００の内側縁部２２０の形状は、カシメ治具３００の形状に整合ししている。その結果、隣接した短フレーム１０および長フレーム１２の内側壁部５０には、カシメ部５４が形成され、短フレーム１０および長フレーム１２と連結部材２００とが固定される。 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 hollow part 30 of the support part 22 of the adjacent short frame 10 and long frame 12. Further, the inner wall portions 50 of the adjacent short frame 10 and long frame 12 are pressed by a caulking jig 300. Here, the shape of the inner edge 220 of the connecting member 200 matches the shape of the crimping jig 300. As a result, a caulking portion 54 is formed on the inner wall portion 50 of the adjacent short frame 10 and long frame 12, and the short frame 10 and long frame 12 and the connecting member 200 are fixed.

本発明の実施例によれば、連結部材２００の内側縁部２２０の形状は、カシメ治具３００の形状に整合するので、短フレーム１０と長フレーム１２に対して連結部材２００を嵌め込めることができる。また、短フレーム１０と長フレーム１２に対して連結部材２００が嵌め込まれるので、短フレーム１０と長フレーム１２に対する連結部材２００の固定を強力にできる。また、内側縁部２２０の凸部２３０がカシメ治具３００の凹部３１０に整合するので、これらの噛み合わせを強化できる。また、内側縁部２２０の凹部２３２がカシメ治具３００の凸部３１２に整合するので、これらの噛み合わせを強化できる。また、カシメ治具３００の凸部３１２に対して連結部材２００の凹部２３２のみがあたるので、カシメ治具３００に加える圧力が小さくてもカシメ深さを深くできる。また、カシメ深さが深くなるので、固定を強力にできる。また、カシメ治具３００に加える圧力が小さくなるので、設備費と動力費を低減できる。 According to the embodiment of the present invention, the shape of the inner edge 220 of the connecting member 200 matches the shape of the crimping jig 300, so that the connecting member 200 can be fitted into the short frame 10 and the long frame 12. it can. Further, since the connecting member 200 is fitted into the short frame 10 and the long frame 12, the connecting member 200 can be strongly fixed to the short frame 10 and the long frame 12. Moreover, since the convex part 230 of the inner side edge part 220 aligns with the concave part 310 of the crimping jig 300, these engagement can be strengthened. Moreover, since the recessed part 232 of the inner edge part 220 aligns with the convex part 312 of the crimping jig 300, these engagement can be strengthened. Further, since only the concave portion 232 of the connecting member 200 hits the convex portion 312 of the caulking jig 300, the caulking depth can be increased even if the pressure applied to the caulking jig 300 is small. In addition, since the caulking depth is deep, fixing can be strong. Further, since the pressure applied to the caulking jig 300 is reduced, the equipment cost and the power cost can be reduced.

また、短フレーム１０と長フレーム１２の内側壁部５０は、内側壁部５０の上端部から２５％の範囲内と、内側壁部５０の下端部から２５％の範囲内とにカシメ部５４を有するので、支持部２２の回転を抑制できる。また、第１連結片２１０ａの内側縁部２２０の形状は、当該内側縁部２２０に重なる長フレーム１２の内側壁部５０を加圧するためのカシメ治具３００の形状に整合するので、第１連結片２１０ａと長フレーム１２との固定を強力にできる。また、第２連結片２１０ｂの内側縁部２２０の形状は、当該内側縁部２２０に重なる短フレーム１０の内側壁部５０を加圧するためのカシメ治具３００の形状に整合するので、第２連結片２１０ｂと短フレーム１０との固定を強力にできる。 Further, the inner wall portion 50 of the short frame 10 and the long frame 12 has a caulking portion 54 within a range of 25% from the upper end portion of the inner wall portion 50 and within a range of 25% from the lower end portion of the inner wall portion 50. Since it has, rotation of the support part 22 can be suppressed. In addition, the shape of the inner edge 220 of the first connecting piece 210a matches the shape of the crimping jig 300 for pressing the inner wall portion 50 of the long frame 12 that overlaps the inner edge 220. The fixing of the piece 210a and the long frame 12 can be strengthened. The shape of the inner edge 220 of the second connecting piece 210b matches the shape of the crimping jig 300 for pressurizing the inner wall 50 of the short frame 10 that overlaps the inner edge 220. The fixing of the piece 210b and the short frame 10 can be strengthened.

（実施例２）
次に、実施例２を説明する。実施例２は、実施例１と同様に、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し、特に隣接したフレームを連結するための連結部材に関する。実施例１における連結部材は、カシメ治具の形状に整合した形状の内側縁部を有する。一方、実施例２における連結部材では、フレームに挿入された状態においてカジメ治具によって加圧された場合に、内側縁部がカシメ治具の形状に整合した形状に変形する。実施例２に係る太陽電池モジュール１００は、図１（ａ）−（ｂ）、図２と同様のタイプである。ここでは、実施例１との差異を中心に説明する。 (Example 2)
Next, Example 2 will be described. Example 2 is similar to Example 1, and relates to a solar cell module in which a plurality of frames are attached so as to surround an outer edge portion of the solar cell panel, and particularly to a connecting member for connecting adjacent frames. The connecting member in the first embodiment has an inner edge portion shaped to match the shape of the caulking jig. On the other hand, in the connection member according to the second embodiment, the inner edge portion is deformed into a shape that matches the shape of the caulking jig when being pressed by the caulking jig while being inserted into the frame. The solar cell module 100 according to Example 2 is the same type as that shown in FIGS. 1 (a)-(b) and FIG. Here, it demonstrates centering on the difference with Example 1. FIG.

図４（ａ）−（ｂ）は、連結部材２００による短フレーム１０と長フレーム１２の連結の構成を示す。これらは、図３（ａ）−（ｂ）と同様に示される。図４（ａ）は、カシメ治具３００による圧力を加える前の構造を示す。第１連結片２１０ａの太陽電池パネル１１０側には第１内側縁部２２０ａが配置され、第１連結片２１０ａにおける第１内側縁部２２０ａの反対側には第２外側縁部２２２ｂが配置される。第２連結片２１０ｂの太陽電池パネル１１０側には第２内側縁部２２０ｂが配置され、第２連結片２１０ｂにおける第２内側縁部２２０ｂの反対側には第２外側縁部２２２ｂが配置される。ここで、第１内側縁部２２０ａと第２内側縁部２２０ｂは、直線状に形成される。 FIGS. 4A and 4B show a configuration for connecting the short frame 10 and the long frame 12 by the connecting member 200. These are shown as in FIGS. 3 (a)-(b). FIG. 4A shows a structure before pressure is applied by the caulking jig 300. A first inner edge 220a is disposed on the solar cell panel 110 side of the first connection piece 210a, and a second outer edge 222b is disposed on the opposite side of the first connection piece 210a to the first inner edge 220a. . A second inner edge 220b is disposed on the solar cell panel 110 side of the second connection piece 210b, and a second outer edge 222b is disposed on the opposite side of the second connection piece 210b to the second inner edge 220b. . Here, the first inner edge 220a and the second inner edge 220b are formed in a straight line.

また、第１連結片２１０ａの第１内側縁部２２０ａと第１外側縁部２２２ａとの間の部分には、孔部２４０と総称される第１孔部２４０ａ、第２孔部２４０ｂがｘ軸方向に並んで配置される。第１孔部２４０ａ、第２孔部２４０ｂは、第１連結片２１０ａをｚ軸方向に貫通しており、その開口部は矩形状を有する。また、第１孔部２４０ａと第２孔部２４０ｂとの間には壁部２４２が配置される。第２連結片２１０ｂも第１連結片２１０ａと同様の構造を有する。 In addition, in a portion between the first inner edge 220a and the first outer edge 222a of the first connecting piece 210a, a first hole 240a and a second hole 240b, which are collectively referred to as a hole 240, are provided on the x axis. Arranged side by side. The first hole 240a and the second hole 240b penetrate the first connecting piece 210a in the z-axis direction, and the opening has a rectangular shape. A wall 242 is disposed between the first hole 240a and the second hole 240b. The second connecting piece 210b has the same structure as the first connecting piece 210a.

図４（ｂ）は、カシメ治具３００による圧力を加えている場合の構造を示す。カシメ治具３００は、第１長フレーム１２ａの第１内側壁部５０ａと、第２短フレーム１０ｂの第２内側壁部５０ｂとを同時に加圧する。加圧によって、第１内側壁部５０ａと第２内側壁部５０ｂが変形するとともに、第１内側壁部５０ａに重なった第１内側縁部２２０ａと、第２内側壁部５０ｂに重なった第２内側縁部２２０ｂも変形する。具体的に説明すると、カシメ治具３００の第１凸部３１２ａに接する第１内側壁部５０ａと第１内側縁部２２０ａとに窪みが生成される。ここで、第１内側壁部５０ａにおける窪みが第１カシメ部５４ａに相当する。これに対応した第１内側縁部２２０ａは第１孔部２４０ａにも面しているので窪みやすく、第１凹部２３２ａが生成される。カシメ治具３００の第２凸部３１２ｂに接する第１内側壁部５０ａと第１内側縁部２２０ａにおいても同様であり、第２カシメ部５４ｂと第２凹部２３２ｂが生成される。 FIG. 4B shows the structure when pressure is applied by the crimping jig 300. The crimping jig 300 simultaneously pressurizes the first inner wall portion 50a of the first long frame 12a and the second inner wall portion 50b of the second short frame 10b. The first inner wall portion 50a and the second inner wall portion 50b are deformed by the pressurization, and the first inner edge portion 220a that overlaps the first inner wall portion 50a and the second inner wall portion 50b that overlaps the second inner wall portion 50b. The inner edge 220b is also deformed. More specifically, a depression is generated in the first inner wall 50a and the first inner edge 220a that are in contact with the first protrusion 312a of the crimping jig 300. Here, the depression in the first inner wall portion 50a corresponds to the first caulking portion 54a. The first inner edge 220a corresponding to this also faces the first hole 240a, so that the first inner edge 220a is easily recessed, and the first recess 232a is generated. The same applies to the first inner wall portion 50a and the first inner edge portion 220a in contact with the second convex portion 312b of the crimping jig 300, and the second crimping portion 54b and the second concave portion 232b are generated.

つまり、第１連結片２１０ａにおける第１孔部２４０ａ、第２孔部２４０ｂは、第１長フレーム１２ａの第１内側壁部５０ａをカシメ治具３００によって加圧する予定の位置に配置される。一方、カシメ治具３００の凹部３１０に接する第１内側壁部５０ａと第１内側縁部２２０ａとには窪みが生成されない。これに対応した第１内側縁部２２０ａは、第１孔部２４０ａに面しておらず、壁部２４２が配置されるので、凸部２３０が生成される。また、第２連結片２１０ｂも第１連結片２１０ａと同様の構造を有する。 That is, the first hole portion 240a and the second hole portion 240b in the first connecting piece 210a are disposed at positions where the first inner wall portion 50a of the first long frame 12a is to be pressed by the caulking jig 300. On the other hand, no depression is generated in the first inner wall 50a and the first inner edge 220a that are in contact with the recess 310 of the crimping jig 300. The first inner edge 220a corresponding to this does not face the first hole 240a, and the wall 242 is disposed, so that the convex portion 230 is generated. The second connecting piece 210b has the same structure as the first connecting piece 210a.

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、隣接した短フレーム１０および長フレーム１２の支持部２２の中空部３０に連結部材２００を挿入させる。さらに、隣接した短フレーム１０および長フレーム１２の内側壁部５０をカシメ治具３００によって加圧する。ここで、連結部材２００の内側縁部２２０と外側縁部２２２との間の部分に、連結部材２００を貫通する孔部２４０が設けられており、カシメ治具３００による加圧によって、孔部２４０の形状が変形する。その結果、連結部材２００には凸部２３０と凹部２３２が形成される。 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 hollow part 30 of the support part 22 of the adjacent short frame 10 and long frame 12. Further, the inner wall portions 50 of the adjacent short frame 10 and long frame 12 are pressed by a caulking jig 300. Here, a hole 240 that penetrates the connecting member 200 is provided in a portion between the inner edge 220 and the outer edge 222 of the connecting member 200, and the hole 240 is pressed by the caulking jig 300. The shape of is deformed. As a result, a convex part 230 and a concave part 232 are formed in the connecting member 200.

本実施例によれば、第１連結片２１０ａにおける孔部２４０が、長フレーム１２の内側壁部５０をカシメ治具３００によって加圧する予定の位置に配置されるので、カシメ治具３００による加圧によって、第１連結片２１０ａに凹部２３２を生成できる。また、第２連結片２１０ｂにおける孔部２４０が、短フレーム１０の内側壁部５０をカシメ治具３００によって加圧する予定の位置に配置されるので、カシメ治具３００による加圧によって、第２連結片２１０ｂに凹部２３２を生成できる。また、短フレーム１０と長フレーム１２に連結部材２００を挿入してから、カシメ治具３００によって、連結部材２００に凹部２３２を生成するので、孔部２４０の大きさを大きくすることで連結部材２００の位置とカシメ治具３００の位置がずれてもこれらの形状を合わせることができる。 According to the present embodiment, the hole 240 in the first connecting piece 210a is disposed at a position where the inner wall 50 of the long frame 12 is to be pressed by the caulking jig 300. Thus, the recess 232 can be generated in the first connecting piece 210a. Further, since the hole 240 in the second connecting piece 210b is disposed at a position where the inner wall 50 of the short frame 10 is to be pressed by the caulking jig 300, the second connecting piece 210b is pressed by the caulking jig 300. A recess 232 can be generated in the piece 210b. Further, since the concave member 232 is generated in the connecting member 200 by the caulking jig 300 after the connecting member 200 is inserted into the short frame 10 and the long frame 12, the connecting member 200 is increased by increasing the size of the hole 240. These shapes can be matched even if the position of the crimping jig 300 and the position of the crimping jig 300 are misaligned.

本実施例の概要は、次の通りである。連結部材２００は、凹部２３２が配置された内側縁部２２０と、当該内側縁部２２０に対応する外側縁部２２２との間の部分に、連結部材２００を貫通する孔部２４０を有してもよい。 The outline of the present embodiment is as follows. The connecting member 200 may have a hole 240 that penetrates the connecting member 200 at a portion between the inner edge 220 where the recess 232 is disposed and the outer edge 222 corresponding to the inner edge 220. Good.

本発明のさらに別の態様もまた、連結部材２００である。この連結部材２００は、太陽電池パネル１１０の外縁部１１６に配置される複数のフレームのうちの隣接した長フレーム１２と短フレーム１０とを連結するための連結部材２００であって、長フレーム１２の中空部３０に挿入される第１連結片２１０ａと、第１連結片２１０ａの一端から太陽電池パネル１１０側を内側として内側に屈曲するとともに、短フレーム１０の中空部３０に挿入される第２連結片２１０ｂとを備える。第１連結片２１０ａの内側縁部２２０と外側縁部２２２との間の部分には、第１連結片２１０ａを貫通する孔部２４０が配置され、第２連結片２１０ｂの内側縁部２２０と外側縁部２２２との間の部分には、第２連結片２１０ｂを貫通する孔部２４０が配置され、第１連結片２１０ａにおける孔部２４０は、長フレーム１２の内側壁部５０をカシメ治具３００によって加圧する予定の位置に配置され、第２連結片２１０ｂにおける孔部２４０は、短フレーム１０の内側壁部５０をカシメ治具３００によって加圧する予定の位置に配置される。 Yet another embodiment of the present invention is also a connecting member 200. The connecting member 200 is a connecting member 200 for connecting the adjacent long frame 12 and the short frame 10 among the plurality of frames disposed on the outer edge portion 116 of the solar cell panel 110. The first connection piece 210a inserted into the hollow portion 30 and the second connection inserted into the hollow portion 30 of the short frame 10 while bending inward from the one end of the first connection piece 210a with the solar cell panel 110 side as the inside. And a piece 210b. A hole 240 passing through the first connecting piece 210a is disposed between the inner edge 220 and the outer edge 222 of the first connecting piece 210a, and the outer edge 220 and the outer side of the second connecting piece 210b are arranged outside. A hole 240 passing through the second connecting piece 210b is disposed between the edge portion 222 and the hole 240 in the first connecting piece 210a. The hole 240 in the second connecting piece 210b is disposed at a position where the inner wall portion 50 of the short frame 10 is to be pressed by the crimping jig 300.

本発明のさらに別の態様もまた、太陽電池モジュール１００の製造方法である。この方法は、太陽電池パネル１１０の外縁部１１６を嵌合すべき中空構造のフレームに、隣接した短フレーム１０と長フレーム１２を連結するための連結部材２００であって、かつ太陽電池パネル１１０側を内側として内側に屈曲する連結部材２００を挿入させるステップと、短フレーム１０と長フレーム１２の内側壁部５０をカシメ治具３００によって加圧するステップとを備える。加圧するステップでは、連結部材２００の内側縁部２２０と外側縁部２２２との間の部分において、連結部材２００を貫通する孔部２４０が、カシメ治具３００の形状に変形する。 Yet another embodiment of the present invention is also a method for manufacturing the solar cell module 100. This method is a connecting member 200 for connecting the adjacent short frame 10 and the long frame 12 to a frame having a hollow structure in which the outer edge portion 116 of the solar cell panel 110 is to be fitted, and on the solar cell panel 110 side. And inserting the connecting member 200 that is bent inward, and pressing the inner wall portions 50 of the short frame 10 and the long frame 12 with a caulking jig 300. In the pressurizing step, the hole 240 penetrating the connecting member 200 is deformed into the shape of the crimping jig 300 in the portion between the inner edge 220 and the outer edge 222 of the connecting member 200.

（実施例３）
次に、実施例３を説明する。実施例３は、これまでと同様に、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し、特に隣接したフレームを連結するための連結部材に関する。前述のごとく、フレームの支持部の高さを高くした場合、連結部材の高さも高くされる。これにより、連結部材の部材使用量（部材費）が増加してしまう。実施例２における連結部材には、軽量化用の孔部（以下、「軽量化孔部」という）が設けられるので、部材使用量が削減される。実施例３に係る太陽電池モジュール１００は、図１（ａ）−（ｂ）、図２と同様のタイプである。ここでは、これまでとの差異を中心に説明する。 (Example 3)
Next, Example 3 will be described. Example 3 relates to a solar cell module in which a plurality of frames are attached so as to surround the outer edge portion of the solar cell panel, and particularly relates to a connecting member for connecting adjacent frames. As described above, when the height of the support portion of the frame is increased, the height of the connecting member is also increased. Thereby, the member usage-amount (member cost) of a connection member will increase. Since the connection member in Example 2 is provided with a hole portion for weight reduction (hereinafter referred to as “light weight reduction hole portion”), the amount of the member used is reduced. The solar cell module 100 according to Example 3 is the same type as that shown in FIGS. 1 (a)-(b) and FIG. Here, it demonstrates centering on the difference from before.

図５は、連結部材２００による短フレーム１０と長フレーム１２の連結の構成を示す。これは、図３（ａ）と同様に示される。第１連結片２１０ａには、軽量用孔部２５０と総称される第１軽量用孔部２５０ａ、第２軽量用孔部２５０ｂが設けられる。第１軽量用孔部２５０ａは、第２連結片２１０ｂ側端近傍に配置され、第２軽量用孔部２５０ｂは、第１連結片端部２１２ａ近傍に配置される。このような位置は、カシメ治具３００による加圧よる力がかかりにくい位置であるといえる。第１軽量用孔部２５０ａ、第２軽量用孔部２５０ｂは、第１連結片２１０ａをｚ軸方向に貫通する。軽量用孔部２５０は、孔部２４０と異なり、カシメ治具３００による加圧によっても変形しにくい。第２連結片２１０ｂも第１連結片２１０ａと同様の構造を有する。 FIG. 5 shows a configuration for connecting the short frame 10 and the long frame 12 by the connecting member 200. This is shown in the same manner as in FIG. The first connecting piece 210a is provided with a first lightweight hole portion 250a and a second lightweight hole portion 250b, which are collectively referred to as a lightweight hole portion 250. The first lightweight hole portion 250a is disposed in the vicinity of the second connection piece 210b side end, and the second lightweight hole portion 250b is disposed in the vicinity of the first connection piece end portion 212a. It can be said that such a position is a position where it is difficult to apply a force applied by the crimping jig 300. The first lightweight hole portion 250a and the second lightweight hole portion 250b penetrate the first connecting piece 210a in the z-axis direction. Unlike the hole portion 240, the lightweight hole portion 250 is not easily deformed even by pressurization by the caulking jig 300. The second connecting piece 210b has the same structure as the first connecting piece 210a.

図６（ａ）−（ｄ）は、連結部材２００による短フレーム１０と長フレーム１２の連結の別の構成を示す。図６（ａ）−（ｂ）は、図４（ａ）−（ｂ）に対して、図５の第１軽量用孔部２５０ａ、第２軽量用孔部２５０ｂを追加した構造を示す。第１孔部２４０ａは、図４（ａ）−（ｂ）の第１孔部２４０ａと、図５の第１軽量用孔部２５０ａとが組み合わされた形状を有する。軽量用孔部２５０は、図５の第２軽量用孔部２５０ｂに相当する。また、第２連結片２１０ｂも第１連結片２１０ａと同様の構造を有する。 6A to 6D show another configuration for connecting the short frame 10 and the long frame 12 by the connecting member 200. FIG. 6 (a)-(b) shows a structure in which the first lightweight hole portion 250a and the second lightweight hole portion 250b in FIG. 5 are added to FIGS. 4 (a)-(b). The first hole portion 240a has a shape in which the first hole portion 240a shown in FIGS. 4A and 4B and the first lightweight hole portion 250a shown in FIG. 5 are combined. The lightweight hole portion 250 corresponds to the second lightweight hole portion 250b in FIG. The second connecting piece 210b has the same structure as the first connecting piece 210a.

図６（ｃ）−（ｄ）は、図６（ａ）−（ｂ）と同様に示されるが、壁部２４２の構造が異なる。ここでの壁部２４２は、カシメ治具３００による加圧方向に沿って配置される。このような壁部２４２の配置により、第１孔部２４０ａと第２孔部２４０ｂの形状も、図６（ａ）−（ｂ）とは異なる。 6 (c)-(d) are shown similarly to FIGS. 6 (a)-(b), but the structure of the wall 242 is different. Here, the wall portion 242 is arranged along the pressurizing direction by the caulking jig 300. Due to the arrangement of the wall portion 242, the shapes of the first hole portion 240 a and the second hole portion 240 b are also different from those in FIGS.

本実施例によれば、軽量用孔部２５０を設けるので、断面積を減少できる。また、断面積が減少するので、部材単価を安くできる。また、断面積が減少するので、連結部材２００を軽量化できる。また、壁部２４２は、カシメ治具３００による加圧方向に配置されるので、加圧による変形を抑制できる。また、加圧による変形が抑制されるので、連結部材２００に凸部２３０を生成しやすくできる。 According to the present embodiment, since the lightweight hole 250 is provided, the cross-sectional area can be reduced. Moreover, since the cross-sectional area is reduced, the unit price of the member can be reduced. Moreover, since the cross-sectional area decreases, the connection member 200 can be reduced in weight. Moreover, since the wall part 242 is arrange | positioned in the pressurization direction by the crimping jig | tool 300, the deformation | transformation by pressurization can be suppressed. Further, since deformation due to pressurization is suppressed, it is possible to easily generate the convex portion 230 in the connecting member 200.

本実施例の概要は、次の通りである。連結部材２００の孔部２４０は、カシメ治具３００による加圧方向に沿った壁部２４２を有してもよい。 The outline of the present embodiment is as follows. The hole part 240 of the connecting member 200 may have a wall part 242 along the pressing direction by the caulking jig 300.
