Description

太陽電池モジュール用ケーブルホルダCable holder for solar cell module
　本発明は、屋根上等に設置される太陽電池モジュールに配線ケーブルを保持させるための太陽電池モジュール用ケーブルホルダに関するものである。 The present invention relates to a solar cell module cable holder for holding a wiring cable in a solar cell module installed on a roof or the like.
　従来より、板状の太陽電池パネルの外周辺をフレームで支持した太陽電池モジュールを屋根上等に設置した場合、太陽電池モジュールに接続された配線ケーブルを屋根瓦やスレート等の屋根材上を這わせると、配線ケーブルによって雨水等の流下が阻害され、屋根材上に水が溜まって、腐敗臭の原因となったり雨漏りの原因となったりする問題がある。そこで、太陽電池モジュールのフレームにおける太陽電池パネルの下側に延出し底壁の一部を形成する延出片に孔を穿設し、その孔を通して結束バンドによって配線ケーブルをフレームに支持させて、配線ケーブが屋根材上に垂れないようにしていた。 Conventionally, when a solar cell module that supports the outer periphery of a plate-shaped solar cell panel with a frame is installed on the roof or the like, the wiring cable connected to the solar cell module is laid on the roof material such as roof tiles and slate. In such a case, the flow of rainwater or the like is hindered by the wiring cable, and water accumulates on the roofing material, causing a problem of decaying odor or rain leakage. Therefore, a hole is drilled in the extending piece that forms a part of the bottom wall extending to the lower side of the solar cell panel in the frame of the solar cell module, and the wiring cable is supported on the frame by the binding band through the hole, The wiring cable was kept from hanging on the roofing material.
　ところで、結束バンドを用いた場合、太陽電池モジュールのフレームと屋根材との間に手を入れて結束バンドをフレームにおける延出片の孔に通す必要があり、作業性が悪い問題があった。そこで、結束バンドに替えて、特許文献１のような、フレームの延出片の孔に係止される係止部材と、係止部材の下端に配線ケーブを保持する帯状の保持部材とを備えた樹脂製の保持具を用いることが考えられ、保持具の係止部材を延出片の孔に対して下側から挿入係止させることで、フレームに保持具を簡単に取付けて配線ケーブルを保持させることができる。 By the way, when the binding band is used, it is necessary to put a hand between the frame of the solar cell module and the roofing material and pass the binding band through the hole of the extension piece in the frame, which has a problem of poor workability. Therefore, instead of the binding band, there is provided a locking member that is locked to the hole of the extending piece of the frame as in Patent Document 1, and a belt-shaped holding member that holds the wiring cable at the lower end of the locking member. It is conceivable to use a resin-made holder, and the holder can be easily attached to the frame by inserting and locking the locking member of the holder from the lower side with respect to the hole of the extension piece. Can be retained.
　しかしながら、従来の結束バンドや特許文献１の保持具は、所定の合成樹脂により形成されており、太陽電池モジュールが設置される使用環境下では、風雨や風雪、温度等の環境変化によって樹脂の劣化が早く進み、配線ケーブルを保持することができなくなり、配線ケーブルが屋根材上に垂れて上記の不具合が発生する問題があった。そのため、結束バンド等を定期的に交換しなければならず、メンテナンスに手間がかかっていた。 However, the conventional binding band and the holder of Patent Document 1 are made of a predetermined synthetic resin, and the resin deteriorates due to environmental changes such as wind, rain, snow, and temperature under the usage environment where the solar cell module is installed. However, the wiring cable cannot be held, and the wiring cable hangs down on the roofing material, resulting in the above problem. For this reason, the binding band and the like have to be periodically replaced, and maintenance is troublesome.
　また、特許文献１の保持具では、太陽電池モジュールに用いた場合、フレームにおける延出片の孔に下側から挿入された係止部材が、延出片の上側で可動片が拡開して抜止めされるようになっているので、孔から係止部材を抜く場合は、作業者が延出片の上側へ手を回して可動片を閉じる必要があるが、フレームと屋根材との間や、フレームの延出片と太陽電池パネルとの間の高さ等によっては、延出片の上側へ手を回すことができず、保持具の係止部材を抜いて保持具を交換することができない問題がある。 Moreover, in the holder of patent document 1, when it uses for a solar cell module, the latching member inserted from the bottom into the hole of the extension piece in a flame | frame expands a movable piece on the upper side of the extension piece. Since it is designed to be removed, when removing the locking member from the hole, it is necessary for the operator to close the movable piece by turning his hand to the upper side of the extension piece. Depending on the height between the extended piece of the frame and the solar cell panel, etc., the hand cannot be turned to the upper side of the extended piece, and the holder is replaced by removing the retaining member of the holder. There is a problem that can not be.
　そこで、本発明は上記の実情に鑑み、耐久性が高く、太陽電池モジュールの配線ケーブルを簡単にフレームに取付けることができると共に容易に交換することができる太陽電池モジュール用ケーブルホルダの提供を課題とするものである。 Accordingly, in view of the above circumstances, the present invention has an object to provide a cable holder for a solar cell module that is highly durable, can easily attach the wiring cable of the solar cell module to the frame, and can be easily replaced. To do.
　上記の課題を解決するために、本発明に係る太陽電池モジュール用ケーブルホルダは、「板状の太陽電池パネルの外周辺をフレームで支持した太陽電池モジュールにおける、フレームの底壁を上下方向へ貫通する孔状又は切欠状の貫通部に対して取付けられ、太陽電池モジュールに接続される配線ケーブルを保持する太陽電池モジュール用ケーブルホルダであって、フレームの底壁の上面と当接可能とされ貫通部の中心軸を挟んで対向配置されると共に互いに離反する方向へ延びた一対の吊掛部と、一対の該吊掛部における貫通部に接近した一方の端部から貫通部を通って底壁の上側から下側へ垂下すると共にフレームの貫通部の内壁と当接可能とされた一対の垂下部と、少なくとも一つの該垂下部の下端と連続し配線ケーブルを保持するケーブル保持部と、一対の前記吊掛部における貫通部よりも遠ざかった他方の端部から一方の端部の上側へ斜めに延びた傾斜部とを具備し、金属線材によって一体形成されている」ことを特徴とする。 In order to solve the above problems, a cable holder for a solar cell module according to the present invention is described as follows. “In a solar cell module in which the outer periphery of a plate-like solar cell panel is supported by a frame, the bottom wall of the frame is vertically penetrated. A solar cell module cable holder that is attached to a hole-shaped or notched through-portion and holds a wiring cable connected to the solar cell module, and can be contacted with the upper surface of the bottom wall of the frame. A pair of hanging parts that are arranged opposite to each other across the central axis of the part and extend away from each other, and a bottom wall that passes through the penetration part from one end close to the penetration part in the pair of hanging parts A pair of hanging parts that are suspended from the upper side to the lower side of the frame and that can be brought into contact with the inner wall of the penetrating portion of the frame, and at least one lower end of the hanging part to be continuous and hold the wiring cable A cable holding portion and an inclined portion extending obliquely from the other end portion farther than the penetrating portion of the pair of the hanging portions to the upper side of the one end portion, and is integrally formed of a metal wire. '' It is characterized by that.
　ここで、フレームの「底壁」としては、フレームの底面の壁を形成するものであれば良く、例えば、「フレームにおける本体部の底面に沿って太陽電池モジュールの内側へ延出した板状の延出片」、「フレームにおける箱状に形成された本体部の底面を形成する部位」、等が挙げられる。 Here, the “bottom wall” of the frame may be anything that forms the wall of the bottom surface of the frame. For example, “a plate-like shape extending inward of the solar cell module along the bottom surface of the main body portion of the frame. “Extending piece”, “part forming the bottom surface of the body portion formed in a box shape in the frame”, and the like.
　また、「ケーブル保持部」としては、「配線ケーブルを保持するための開口が上側に形成されたコ字状又はＵ字状のもの」、「配線ケーブルを保持するために上側に形成された開口を閉鎖可能としたもの」、「保持した複数の配線ケーブルを締付けることができるもの」、「金属線材の弾性力によって配線ケーブルを挟持するもの」、等が挙げられる。 In addition, as the “cable holding portion”, “a U-shaped or U-shaped opening in which an opening for holding a wiring cable is formed on the upper side”, “an opening formed on the upper side to hold the wiring cable” Can be closed ”,“ can hold a plurality of held distribution cables ”,“ can hold the distribution cables by the elastic force of the metal wire ”, and the like.
　更に、「金属線材」としては、「ステンレス鋼線材」、「アルミ線材」、「バネ鋼線材」、「燐青銅線材」、「銅線材」、等が挙げられる。また、金属線材の断面形状は、円形状であっても良いし、多角形状であっても良い。 Furthermore, examples of the “metal wire” include “stainless steel wire”, “aluminum wire”, “spring steel wire”, “phosphor bronze wire”, “copper wire”, and the like. In addition, the cross-sectional shape of the metal wire may be circular or polygonal.
　本発明の太陽電池モジュール用ケーブルホルダ（以下、単にケーブルホルダとも称す）を太陽電池モジュールのフレームに取付ける場合は、フレームにおける底壁の貫通部に対して、下側からケーブルホルダの一対の傾斜部を上側へ向けて貫通部に挿入すると、傾斜部が貫通部の下端に当接することで、貫通部の中心軸側が高くなった傾斜部のカム作用により、ケーブルホルダの上昇に伴って傾斜部自体が貫通部の中心軸側（互いに接近する方向）へ移動することとなる。このケーブルホルダは、傾斜部の移動と共に、傾斜部と連続した吊掛部や垂下部等も、貫通部の中心軸側へと移動することとなる。この状態で、更にケーブルホルダを上昇させると、傾斜部の下端側も貫通部内へと進入し、傾斜部の下端と連続した吊掛部や垂下部等も貫通部内へと進入することとなる。 When the cable holder for a solar cell module of the present invention (hereinafter also simply referred to as a cable holder) is attached to the frame of the solar cell module, a pair of inclined portions of the cable holder from the lower side with respect to the through portion of the bottom wall of the frame. Is inserted into the penetrating portion upward, and the inclined portion contacts the lower end of the penetrating portion, so that the inclined portion itself as the cable holder rises due to the cam action of the inclined portion with the central axis side of the penetrating portion raised. Will move to the central axis side of the penetrating part (direction approaching each other). With this cable holder, as the inclined portion moves, the hanging portion and the hanging portion that are continuous with the inclined portion also move toward the central axis of the penetrating portion. When the cable holder is further raised in this state, the lower end side of the inclined portion also enters the penetrating portion, and a hanging portion, a hanging portion, or the like continuous with the lower end of the inclined portion also enters the penetrating portion.
　そして、傾斜部の下端が貫通部を抜けて底壁の上側へ到達したら、一対の傾斜部を互いに離反する方向へと移動させて吊掛部から垂下する垂下部を、貫通部の内壁と当接させると共に、一対の吊掛部を底壁の上面と当接させる。これにより、ケーブルホルダが、貫通部を通してフレームの底壁に吊掛けられた状態となり、その状態で底壁の下側に位置したケーブル保持部に配線ケーブルを保持させることができるようになる。なお、金属線材により形成されたケーブルホルダの弾性力によって、一対の傾斜部（吊掛部）を互いに離反する方向へ移動させるようにしても良い。 Then, when the lower end of the inclined part passes through the penetration part and reaches the upper side of the bottom wall, the pair of inclined parts are moved away from each other, and the hanging part hanging from the hanging part is brought into contact with the inner wall of the penetration part. The pair of hanging portions are brought into contact with the upper surface of the bottom wall. As a result, the cable holder is suspended from the bottom wall of the frame through the penetrating portion, and the cable can be held by the cable holding portion located below the bottom wall in this state. In addition, you may make it move a pair of inclination part (hanging part) to the direction which mutually separates with the elastic force of the cable holder formed with the metal wire.
　一方、ケーブルホルダを太陽電池モジュールのフレームから取外す場合は、一対の吊掛部と夫々連続した一対の垂下部が、貫通部を通して底壁の下側へ垂下しているので、底壁の下側からそれら垂下部を互いに接近する方向へ移動させることで、底壁の上面と当接した一対の吊掛部を互いに接近させることができる。そして、一対の吊掛部が貫通部を通過可能となるまで垂下部を互いに接近させた状態で、ケーブルホルダを降下させると、フレームの貫通部（底壁）からケーブルホルダを取外すことができる。 On the other hand, when removing the cable holder from the frame of the solar cell module, the pair of hanging parts that are continuous with the pair of hanging parts respectively hang down to the lower side of the bottom wall through the penetration part. By moving these hanging parts in a direction approaching each other, the pair of hanging parts in contact with the upper surface of the bottom wall can be brought close to each other. When the cable holder is lowered in a state where the hanging parts are close to each other until the pair of hanging parts can pass through the penetration part, the cable holder can be detached from the penetration part (bottom wall) of the frame.
　従って、本発明によると、ケーブルホルダを金属線材によって形成しているので、従来の樹脂製のものと比較して、風雨や風雪、温度等の環境変化に対する耐久性を高めることができ、メンテナンスに係る手間を簡略化することができる。また、貫通部を通して底壁の下側に垂下した一対の垂下部を、互いに接近する方向へ移動させることで、作業者が底壁の上側へ手を回さなくても、底壁の下側からケーブルホルダを簡単に取外すことができ、ケーブルホルダを容易に交換することができると共に、メンテナンス性を高めることができる。 Therefore, according to the present invention, since the cable holder is formed of a metal wire material, durability against environmental changes such as wind and rain, wind and snow, and temperature can be increased and maintenance can be performed as compared with conventional resin ones. Such trouble can be simplified. In addition, by moving a pair of hanging parts that hang down to the lower side of the bottom wall through the penetrating part in a direction approaching each other, the operator can move the lower side of the bottom wall without turning the hand to the upper side of the bottom wall. Thus, the cable holder can be easily removed, the cable holder can be easily replaced, and the maintainability can be improved.
　また、ケーブルホルダに、一対の傾斜部を備えているので、フレームにおける底壁の貫通部に対して、下側からケーブルホルダを挿入するだけで簡単にケーブルホルダを取付けることができ、太陽電池モジュールの設置に係る作業性を向上させることができる。 Moreover, since the cable holder is provided with a pair of inclined portions, the cable holder can be easily attached to the through portion of the bottom wall of the frame by simply inserting the cable holder from below. The workability related to the installation of can be improved.
　更に、貫通部の内壁と当接する一対の垂下部を備えているので、夫々の吊掛部と垂下部とでＬ字状に底壁の上面と貫通部の内壁とを押えることができ、貫通部内でケーブルホルダがガタツクのを防止することができると共に、ケーブルホルダが吊掛部を軸心として回動するのを抑制することができる。 Furthermore, since it has a pair of hanging parts that contact the inner wall of the penetrating part, the upper surface of the bottom wall and the inner wall of the penetrating part can be pressed in an L shape with each hanging part and hanging part, It is possible to prevent the cable holder from rattling in the portion and to prevent the cable holder from rotating about the hanging portion as an axis.
　なお、ケーブルホルダにおける離反した一対の吊掛部（垂下部および傾斜部）は、傾斜部の上端同士を接続することで互いに連続した状態としても良いし、ケーブル保持部を介して一対の垂下部の下端側同士を接続することで互いに連続した状態としても良い。 The pair of hanging parts (hanging part and inclined part) separated from each other in the cable holder may be connected to each other by connecting the upper ends of the inclined parts, or a pair of hanging parts via the cable holding part. It is good also as a mutually continuous state by connecting the lower end sides of each other.
　また、本発明に係る太陽電池モジュール用ケーブルホルダは、上記の構成に加えて、「少なくとも一つの前記垂下部の下端と連続すると共に前記吊掛部が延びた方向に対して直角方向へ延び、フレームの底壁の下面と当接可能な当接部を更に具備する」ことを特徴としても良い。 Moreover, the cable holder for the solar cell module according to the present invention has, in addition to the above-described configuration, “continuous with the lower end of at least one hanging portion and extends in a direction perpendicular to the direction in which the hanging portion extends, It may further include a contact portion that can contact the lower surface of the bottom wall of the frame ”.
　ところで、配線ケーブルを保持するためのケーブルホルダを金属線材で形成するようにした場合、フレームの底壁の上面に対して吊掛部が線接触に近い状態で当接することとなるので、ケーブルホルダ全体が一対の吊掛部を軸心として回動し易くなる可能性がある。そのため、ケーブルホルダをフレーム（底壁）に取付けた状態で、ケーブル保持部に配線ケーブルを保持させる場合、ケーブルホルダの回動によって垂下したケーブル保持部が太陽電池モジュールの内側へ移動してしまうと、ケーブル保持部への配線ケーブルの保持作業が行い難くなる虞がある。また、ケーブルホルダがフレームの底壁に対して容易に回動することができると、風等の影響によって配線ケーブルと共にケーブルホルダが揺れ易くなり、長期に亘ってケーブルホルダが揺れ続けると、ケーブルホルダとフレームとが当接する部位で摩擦が発生し、ケーブルホルダやフレームが摩耗して不具合が発生する虞がある。 By the way, when the cable holder for holding the wiring cable is formed of a metal wire, the hanging portion comes into contact with the upper surface of the bottom wall of the frame in a state close to line contact. There is a possibility that the whole may be easily rotated about the pair of hanging portions as axes. Therefore, when holding the wiring cable in the cable holding portion with the cable holder attached to the frame (bottom wall), if the cable holding portion suspended by the rotation of the cable holder moves to the inside of the solar cell module There is a risk that it will be difficult to hold the wiring cable in the cable holding portion. In addition, if the cable holder can be easily rotated with respect to the bottom wall of the frame, the cable holder easily shakes together with the wiring cable due to the influence of wind or the like. If the cable holder continues to shake for a long time, the cable holder Friction is generated at the part where the frame and the frame come into contact with each other, and the cable holder or the frame may be worn out to cause a problem.
　本発明によると、吊掛部に対して直角方向へ延びた当接部を底壁の下面に当接させるようにしているので、当接部によって吊掛部を軸心としてケーブルホルダが回動するのを防止することができる。従って、太陽電池モジュールのフレームに取付けられたケーブルホルダに対して配線ケーブルを保持させる際に、ケーブルホルダのケーブル保持部が回動して太陽電池モジュールの内側へ移動してしまうのを防止することができ、配線ケーブルの保持作業を行い易くすることができる。 According to the present invention, the abutting portion extending in a direction perpendicular to the hanging portion is brought into contact with the lower surface of the bottom wall, so that the cable holder rotates around the hanging portion as an axis by the abutting portion. Can be prevented. Therefore, when the wiring cable is held with respect to the cable holder attached to the frame of the solar cell module, the cable holding portion of the cable holder is prevented from rotating and moving to the inside of the solar cell module. It is possible to facilitate the holding work of the wiring cable.
　また、当接部によって吊掛部を軸心としてケーブルホルダが回動するのを防止することができる。つまり、フレームに対してケーブルホルダを揺れ難くすることができるので、ケーブルホルダとフレームとの間で摩擦が発生するのを可及的に抑制することができ、摩擦によってケーブルホルダやフレームが摩耗して不具合が発生するのを防止することができると共に、ケーブルホルダやフレーム（太陽電池モジュール）の耐久性を高めることができる。 Also, the contact portion can prevent the cable holder from rotating about the hanging portion as an axis. In other words, since the cable holder can be made difficult to swing with respect to the frame, the occurrence of friction between the cable holder and the frame can be suppressed as much as possible, and the cable holder and the frame are worn by the friction. Thus, it is possible to prevent the occurrence of problems and to increase the durability of the cable holder and the frame (solar cell module).
　なお、ケーブルホルダの当接部を、ケーブル保持部に対して配線ケーブルを保持する側（太陽電池モジュールの外側）とは反対側のみに底壁の下面と当接するようにしても良く、これにより、ケーブルホルダに配線ケーブルを保持させる際に、ケーブル保持部を作業者側へ回動させることができるので、ケーブル保持部が作業者側に近くなり、配線ケーブルの保持作業をより行い易くすることができる。 The abutting portion of the cable holder may be abutted with the lower surface of the bottom wall only on the side opposite to the side holding the wiring cable (outside of the solar cell module) with respect to the cable holding portion. When holding the wiring cable in the cable holder, the cable holding part can be turned to the worker side, so that the cable holding part is closer to the worker side and the holding work of the wiring cable is made easier. Can do.
　また、本発明に係る太陽電池モジュール用ケーブルホルダは、上記の構成に加えて、「前記傾斜部の上端から貫通部を通ってフレームの底壁の上側から下側へ延出する延出部と、該延出部の下端と連続すると共に前記吊掛部が延びた方向に対して直角方向へ延び、フレームの底壁の下面と当接可能な当接部とを更に具備する」ことを特徴としても良い。 Further, the solar cell module cable holder according to the present invention includes, in addition to the above-described configuration, an “extending portion that extends from the upper end of the inclined portion to the lower side through the through portion and the bottom wall of the frame. , Further comprising an abutting portion that is continuous with the lower end of the extending portion and extends in a direction perpendicular to the direction in which the hanging portion extends and is capable of abutting against the lower surface of the bottom wall of the frame. It is also good.
　ところで、垂下部の下端にフレームにおける底壁の下面と当接する当接部を連続させるようにした場合、垂下部の下端にはケーブル保持部が連続しているので、一対の垂下部に対して、一方に当接部を他方にケーブル保持部を連続させるようにするか、或いは、垂下部とケーブル保持部との間に当接部が形成されるように線材を屈曲させるようにすることが考えられる。そして、垂下部とケーブル保持部との間に当接部を形成するようにした場合、蓋然的に、線材を折返して形成することとなるので、配線ケーブルを保持することでケーブル保持部からかかる荷重が、ケーブル保持部と垂下部との間に配置された当接部を形成するための折返した部位を開かせる方向へ作用することとなり、折返した部位が開くと当接部としての作用効果が望めなくなる虞がある。 By the way, when the abutting portion that abuts the lower surface of the bottom wall of the frame is made continuous with the lower end of the hanging portion, the cable holding portion is continuous with the lower end of the hanging portion. Either the abutment part on one side and the cable holding part on the other side may be continuous, or the wire may be bent so that the abutment part is formed between the hanging part and the cable holding part. Conceivable. And, when the abutting part is formed between the hanging part and the cable holding part, the wire material is folded back and formed, so it is necessary to hold the wiring cable from the cable holding part. The load acts in the direction to open the folded part for forming the contact part arranged between the cable holding part and the hanging part. When the folded part is opened, the effect as the contact part is achieved. May not be expected.
　本発明によると、フレームの底壁の下面に当接する当接部を、傾斜部の上端から下方へ延出した延出部の下端と連続させているので、垂下部とケーブル保持部との間に当接部を形成するようにした場合と比較して、ケーブル保持部から荷重がかかっても当接部の屈曲が伸ばされて当接部としての作用効果が低下してしまうのを確実に回避させることができ、当接部を備えたケーブルホルダを確実に具現化することができる。また、吊掛部に対して直角方向へ延びて底壁の下面に当接する当接部を備えているので、上述したように、吊掛部を軸心としてケーブルホルダが回動するのを防止することができ、上述と同様の作用効果を奏することができる。 According to the present invention, the abutting portion that abuts the lower surface of the bottom wall of the frame is connected to the lower end of the extending portion that extends downward from the upper end of the inclined portion. Compared to the case where the contact portion is formed on the cable, it is ensured that even if a load is applied from the cable holding portion, the bending of the contact portion is extended and the effect as the contact portion is reduced. The cable holder provided with the contact portion can be reliably realized. Moreover, since the contact portion that extends in a direction perpendicular to the hanging portion and contacts the lower surface of the bottom wall is provided, as described above, the cable holder is prevented from rotating around the hanging portion as an axis. It is possible to achieve the same effects as described above.
　更に、本発明に係る太陽電池モジュール用ケーブルホルダは、上記の構成に加えて、「前記傾斜部は、一対の前記吊掛部における他方の端部から延びた上端同士が連結されている」ことを特徴としても良い。 Furthermore, the cable holder for the solar cell module according to the present invention has, in addition to the above-described configuration, “the upper ends of the inclined portions extending from the other ends of the pair of hanging portions are connected”. It may be characterized.
　本発明によると、ケーブルホルダにおける一対の傾斜部の上端同士を連結しているので、傾斜部を介して一対の吊掛部や垂下部を連続した一体のものとすることができる。また、一対の傾斜部の上端同士を連結しており、一対の傾斜部に対して弾性力を付与することができるので、貫通部を通して底壁へケーブルホルダを取付けたり取外したりする際に、傾斜部を介して吊掛部を底壁の上面と当接可能な位置へ自動的に復帰させることができ、ケーブルホルダの取付け取外しを容易にすることができる。 According to the present invention, since the upper ends of the pair of inclined parts in the cable holder are connected to each other, the pair of hanging parts and hanging parts can be made continuous through the inclined part. In addition, the upper ends of the pair of inclined portions are connected to each other, and an elastic force can be applied to the pair of inclined portions. Therefore, when the cable holder is attached to or removed from the bottom wall through the through portion, the inclined portions are inclined. The hanging portion can be automatically returned to a position where it can come into contact with the upper surface of the bottom wall via the portion, and the attachment and removal of the cable holder can be facilitated.

The inclination extending from the other end of the lower hanging part to the lower end of the hanging part hanging from one end of the upper hanging part after being separated so as to increase the distance The lower end of the hanging portion that is connected to the upper end of the portion and is suspended from one end portion of the lowermost hanging portion is continuous with the cable holding portion ”.
　本発明によると、一対の吊掛部、垂下部、及び傾斜部を上下方向へ複数備えると共に、下側の吊掛部（垂下部）ほど互に離反した距離（間隔）を大きくしているので、フレームの底壁に形成された貫通部の径や幅に応じた間隔の吊掛部を底壁の上面に当接させる（吊掛ける）ようにすれば良く、一つのケーブルホルダで様々な大きさの貫通部に対応することができ、汎用性を高めることができると共に、予め用意するケーブルホルダの種類を少なくすることができ、コストを低減させることができる。 According to the present invention, since a plurality of pairs of hanging parts, hanging parts, and inclined parts are provided in the vertical direction, the lower hanging parts (hanging parts) have a larger distance (interval) away from each other. It is only necessary that the hanging part with a spacing corresponding to the diameter and width of the through part formed on the bottom wall of the frame is brought into contact with (hanging on) the upper surface of the bottom wall. In addition to being able to cope with the through-holes, the versatility can be improved, the types of cable holders prepared in advance can be reduced, and the cost can be reduced.

Although illustration is omitted, a substrate box is attached to the lower surface of the solar cell panel 2, and a wiring cable 4 having a predetermined length is connected to the substrate box.
　太陽電池モジュール１のフレーム３は、上部に太陽電池モジュール１の内側へ向けて開放された溝状を有するパネル保持部３ａと、パネル保持部３ａの下側に形成され縦長箱状の本体部３ｂと、本体部３ｂの下端から下面に沿って太陽電池モジュール１の内側へ延びた延出片３ｃと、を備えている。このフレーム３は、図示するように、パネル保持部３ａと本体部３ｂの太陽電池モジュール１における外側面が、互いに面一となるように形成されている。また、フレーム３は、延出片３ｂの所定位置に上下方向へ貫通した孔状の貫通部３ｄを備えている。 The frame 3 of the solar cell module 1 includes a panel holding portion 3a having a groove shape opened upward toward the inside of the solar cell module 1, and a vertically long box-shaped main body portion 3b formed below the panel holding portion 3a. And an extending piece 3c extending inward of the solar cell module 1 along the lower surface from the lower end of the main body 3b. As shown in the figure, the frame 3 is formed such that the outer surfaces of the panel holding portion 3a and the main body portion 3b in the solar cell module 1 are flush with each other. Further, the frame 3 includes a hole-shaped through portion 3d penetrating in a vertical direction at a predetermined position of the extending piece 3b.
　なお、本例のフレーム３では、本体部３ｂの底面を形成する部位と、延出片３ｃとでフレーム３の底壁を形成している。また、本例の貫通部３ｄは、太陽電池モジュール１を設置するために予めフレーム３に穿設されているものである。更に、フレーム３の断面形状は、図示した形状に限定するものではなく、図示しない他の断面形状であっても良い。 In the frame 3 of this example, the bottom wall of the frame 3 is formed by the portion that forms the bottom surface of the main body 3b and the extending piece 3c. Further, the penetration portion 3d of this example is previously drilled in the frame 3 in order to install the solar cell module 1. Furthermore, the cross-sectional shape of the frame 3 is not limited to the illustrated shape, and may be another cross-sectional shape not shown.
　この太陽電池モジュール１は、図示は省略するが、屋根材５上に取付けられた長尺状の架台や、太陽電池モジュール１のフレーム３を保持し屋根材５に直接取付けられる固定金具等の公知の部材や方法を用いて屋根材５上に設置されるようになっており、フレーム３の下面と屋根材５との間に隙間が形成されるようになっている（図１を参照）。なお、図１中、符号６は、太陽電池パネル２と、フレーム３のパネル保持部３ａとの間に配置されたシール部材である。 Although not shown in the figure, this solar cell module 1 is known as a long base attached to the roof material 5, a fixing bracket that holds the frame 3 of the solar cell module 1 and is directly attached to the roof material 5. Are installed on the roofing material 5 using a member or method, and a gap is formed between the lower surface of the frame 3 and the roofing material 5 (see FIG. 1). In FIG. 1, reference numeral 6 denotes a seal member disposed between the solar cell panel 2 and the panel holding portion 3 a of the frame 3.
　本実施形態における太陽電池モジュール用ケーブルホルダ１０は、図１及び図２に示すように、フレーム３の延出片３ｃの上面と当接可能とされ貫通部３ｄの中心軸を挟んで対向配置されると共に互いに離反する方向へ延びた一対の吊掛部１１と、一対の吊掛部１１における貫通部３ｄに接近した一方の端部から貫通部３ｄを通って延出片３ｃの上側から下側へ垂下する一対の垂下部１２と、垂下部１２の下端と連続し配線ケーブル４を保持する一対のケーブル保持部１３と、を備えている。 As shown in FIGS. 1 and 2, the solar cell module cable holder 10 according to the present embodiment can be brought into contact with the upper surface of the extension piece 3c of the frame 3 and is disposed so as to face the center axis of the through-hole 3d. And a pair of hanging portions 11 extending in a direction away from each other, and one end near the penetrating portion 3d in the pair of hanging portions 11 from the upper side to the lower side of the extending piece 3c through the penetrating portion 3d A pair of hanging portions 12 that hang down and a pair of cable holding portions 13 that are continuous with the lower end of the hanging portion 12 and hold the wiring cable 4 are provided.
　また、ケーブルホルダ１０は、一対の吊掛部１１における貫通部３ｄよりも遠ざかった他方の端部から一方の端部の上側へ斜めに延びた傾斜部１４と、傾斜部１４の上端から貫通部３ｄを通って延出片３ｃの上側から下側へ延出する延出部１５と、延出部１５の下端と連続すると共に吊掛部１１が延びた方向に対して直角方向へ延び延出片３ｃの下面と当接可能な当接部１６と、を備えている。 In addition, the cable holder 10 includes an inclined portion 14 that extends obliquely from the other end portion farther than the penetrating portion 3d in the pair of hanging portions 11 to the upper side of the one end portion, and a penetrating portion from the upper end of the inclined portion 14 An extension part 15 extending from the upper side to the lower side of the extension piece 3c through 3d and a lower end of the extension part 15 and extending in a direction perpendicular to the direction in which the hanging part 11 extends. And an abutting portion 16 capable of abutting against the lower surface of the piece 3c.
　本例のケーブルホルダ１０における垂下部１２は、図示するように、貫通部３ｄよりも下側に位置する部位で、吊掛部１１の延びた方向と同じ方向で下端が貫通部３ｄの中心軸から遠ざかる方向へ斜めに折曲っている。これにより、一対のケーブル保持部は、保持した配線ケーブル４の軸方向に対して、貫通部３ｄの外径よりも１．５倍～３．０倍（本例では、約２．５倍）の間隔で互いに離反した状態となっている。 The hanging portion 12 in the cable holder 10 of the present example is a portion located below the penetrating portion 3d as shown in the figure, and the lower end is the central axis of the penetrating portion 3d in the same direction as the extending direction of the hanging portion 11. It is bent diagonally in the direction away from it. Accordingly, the pair of cable holding portions is 1.5 to 3.0 times (in this example, about 2.5 times) the outer diameter of the through portion 3d with respect to the axial direction of the held wiring cable 4. Are separated from each other at intervals of.
　一方、ケーブル保持部４は、当接部１６が延びた側とは反対側に開口し配線ケーブル４を挿入するための挿入口１３ａを備えており、挿入口１３ａ側の端部同士が連結部１７によって互いに連結されている。これにより、一対の垂下部１２が、通常の状態で貫通部３ｄの内壁に当接可能な間隔となるようになっていると共に、一対の垂下部１２（吊掛部１１）を互いに接近する方向へ移動させた場合に、弾性力が作用して元の状態に復帰させることができるようになっている。 On the other hand, the cable holding part 4 is provided with an insertion port 13a that opens on the opposite side to the side on which the contact part 16 extends, and for inserting the wiring cable 4, and the ends on the insertion port 13a side are connected to each other. 17 are connected to each other. Thereby, while a pair of hanging parts 12 become the space | interval which can contact | abut to the inner wall of the penetration part 3d in a normal state, it is the direction which mutually approaches a pair of hanging parts 12 (hanging part 11) When it is moved, the elastic force acts so that the original state can be restored.
　また、ケーブル保持部１３は、四つの配線ケーブル４を収容保持することができる大きさとされている。また、ケーブル保持部１３は、配線ケーブル４の軸方向から見ると外形が概ね矩形状に形成されており、三隅が配線ケーブル４の外径に略沿った円弧状に形成されていると共に、三辺の中央がケーブル保持部１３の内側へ突出したＶ字状に形成されている。これにより、ケーブル保持部１３に保持された配線ケーブル４を動き難くすることができるようになっている。なお、ケーブル保持部１３は、挿入口１３ａ側の端部付近が当接部１６の延びた側とは反対側へ折曲っており、配線ケーブル４をケーブル保持部１３内へ挿入し易くすることができるようになっている。 Further, the cable holding portion 13 has a size capable of accommodating and holding the four wiring cables 4. In addition, the cable holding portion 13 has a substantially rectangular outer shape when viewed from the axial direction of the wiring cable 4, three corners are formed in an arc shape substantially along the outer diameter of the wiring cable 4, and three The center of the side is formed in a V shape projecting inward of the cable holding portion 13. Thereby, it is possible to make the wiring cable 4 held by the cable holding portion 13 difficult to move. The cable holding portion 13 is bent near the end on the insertion port 13 a side to the side opposite to the side where the contact portion 16 extends, so that the wiring cable 4 can be easily inserted into the cable holding portion 13. Can be done.
　なお、本例のケーブルホルダ１０は、断面が円形状のステンレス鋼線材によって形成されており、一本の線材を屈曲して形成されている。また、線材の外径は、０．５ｍｍ～２．０ｍｍのものを用いている。 The cable holder 10 of this example is formed of a stainless steel wire having a circular cross section, and is formed by bending a single wire. The wire rod has an outer diameter of 0.5 mm to 2.0 mm.
　次に、本例のケーブルホルダ１０の取付け取外しについて説明する。まず、ケーブルホルダ１０を太陽電池モジュール１のフレーム３に取付ける場合は、フレーム３における延出片３ｃの貫通部３ｄの下側に、一対の傾斜部１４が上側を向くようにケーブルホルダ１０を配置した上で、一対の傾斜部１４が貫通部３ｄへ挿入されるようにケーブルホルダ１０を上昇させる。このケーブルホルダ１０の上昇により一対の傾斜部１４が貫通部３ｄの下端に当接すると、傾斜した傾斜部１４のカム作用により、傾斜部１４自体がケーブルホルダ１０の上昇に従って貫通部３ｄの中心軸側（互いに接近する方向）へ移動することとなり、傾斜部１４の移動と共に吊掛部１１や垂下部１２等も、貫通部３ｄの中心軸側へと移動することとなる。 Next, attachment / detachment of the cable holder 10 of this example will be described. First, when the cable holder 10 is attached to the frame 3 of the solar cell module 1, the cable holder 10 is disposed below the through-hole 3d of the extension piece 3c in the frame 3 so that the pair of inclined portions 14 face upward. After that, the cable holder 10 is raised so that the pair of inclined portions 14 are inserted into the through portions 3d. When the pair of inclined portions 14 come into contact with the lower end of the penetrating portion 3d due to the rise of the cable holder 10, the inclined portion 14 itself is moved along the center axis of the penetrating portion 3d by the cam action of the inclined inclined portion 14. Accordingly, the hanging portion 11 and the hanging portion 12 move to the central axis side of the penetrating portion 3d as the inclined portion 14 moves.
　この状態で、更にケーブルホルダ１０を上昇させると、傾斜部１４の下端側も貫通部３ｄ内へと進入すると共に吊掛部１１や垂下部１２等も貫通部３ｄ内へと進入することとなる。そして、ケーブルホルダ１０を更に上昇させて、傾斜部１４の下端が貫通部３ｄを抜けて延出片３ｃの上側へ到達すると、一対のケーブル保持部１３を連結する連結部１７からかかる弾性力によって、一対の傾斜部１４が互いに離反する方向へと移動し、一対の垂下部１２や延出部１５が貫通部３ｄの内壁と当接した状態となる。これにより、ケーブルホルダ１０の一対の吊掛部１１が延出片３ｃの上面と当接した状態となると共に、一対の当接部１６が延出片３ｃの下面と当接した状態となり、ケーブルホルダ１０がフレーム３へ取付けられた状態となる。 When the cable holder 10 is further raised in this state, the lower end side of the inclined portion 14 also enters the through portion 3d, and the hanging portion 11, the hanging portion 12 and the like also enter the through portion 3d. . When the cable holder 10 is further raised and the lower end of the inclined portion 14 passes through the through portion 3d and reaches the upper side of the extending piece 3c, the elastic force applied from the connecting portion 17 that connects the pair of cable holding portions 13 The pair of inclined portions 14 move away from each other, and the pair of hanging portions 12 and the extending portions 15 are in contact with the inner wall of the penetrating portion 3d. As a result, the pair of hanging portions 11 of the cable holder 10 are in contact with the upper surface of the extension piece 3c, and the pair of contact portions 16 are in contact with the lower surface of the extension piece 3c. The holder 10 is attached to the frame 3.
　そして、太陽電池モジュール１のフレーム３へケーブルホルダ１０を取付けたら、一対のケーブル保持部１３が互いに離反した方向と、保持する配線ケーブル４の延びた方向とが略一致するように、貫通部３ｄの中心軸周りにケーブルホルダ１０を回転させる。なお、本例では、貫通部３ｄが円形状の孔とされており、ケーブルホルダ１０を容易に回転させることができるようになっている。その後、ケーブル保持部１３の挿入口１３ａを介して、ケーブル保持部１３へ配線ケーブル４を保持させることで、太陽電池モジュール１の配線ケーブル４を保持することができる。なお、本例では、配線ケーブル４が、ケーブルホルダ１０が取付けられたフレーム３の延びた方向と同じ方向へ延びたものを示したが、フレーム３に対して直角方向へ延びた配線ケーブル４を保持するようにしても良いし、また、ケーブル保持部１２の挿入口１３ａが太陽電池モジュール１の外側を向くようにケーブルホルダ１０を取付けても良い。 Then, when the cable holder 10 is attached to the frame 3 of the solar cell module 1, the through portion 3d so that the direction in which the pair of cable holding portions 13 are separated from each other and the extending direction of the wiring cable 4 to be held substantially coincide with each other. The cable holder 10 is rotated around the central axis. In this example, the penetration part 3d is a circular hole so that the cable holder 10 can be easily rotated. Then, the wiring cable 4 of the solar cell module 1 can be hold | maintained by making the cable holding part 13 hold | maintain the wiring cable 4 via the insertion port 13a of the cable holding part 13. FIG. In this example, the wiring cable 4 extends in the same direction as the extending direction of the frame 3 to which the cable holder 10 is attached. However, the wiring cable 4 extending in a direction perpendicular to the frame 3 is used. You may make it hold | maintain, and you may attach the cable holder 10 so that the insertion port 13a of the cable holding part 12 may face the outer side of the solar cell module 1. FIG.
　一方、太陽電池モジュール１０のフレーム３からケーブルホルダ１０を取外す場合は、太陽電池モジュール１０（フレーム３の延出片３ｃ）の下側において、貫通部３ｄを通して延出片３ｃの下側へ垂下した一対の垂下部１２を互いに接近する方向へ移動させることで、延出片３ｃの上面と当接した一対の吊掛部１１を互いに接近させ、それら一対の吊掛部１１が貫通部３ｄを通過可能となるまで一対の垂下部１２を互いに接近させた状態で、ケーブルホルダ１０を降下させると、フレーム３の貫通部３ｄ（延出片３ｃ）からケーブルホルダ１０を取外すことができる。 On the other hand, when removing the cable holder 10 from the frame 3 of the solar cell module 10, it hangs down to the lower side of the extension piece 3 c through the through portion 3 d on the lower side of the solar cell module 10 (extension piece 3 c of the frame 3). By moving the pair of hanging parts 12 toward each other, the pair of hanging parts 11 in contact with the upper surface of the extension piece 3c are brought close to each other, and the pair of hanging parts 11 pass through the through part 3d. When the cable holder 10 is lowered in a state where the pair of hanging portions 12 are close to each other until possible, the cable holder 10 can be removed from the through portion 3d (extending piece 3c) of the frame 3.
　このように、本実施形態のケーブルホルダ１０によると、ケーブルホルダ１０をステンレス鋼の線材によって形成しているので、従来の樹脂製のものと比較して、風雨や風雪、温度等の環境変化に対する耐久性を高めることができ、メンテナンスに係る手間を簡略化することができる。また、太陽電池モジュール１におけるフレーム３の貫通部３ｄを通して延出片３ｃの下側へ垂下した一対の垂下部１２を、互いに接近する方向へ移動させることで、作業者が延出片３ｃの上側へ手を回さなくても、延出片３ｃの下側からケーブルホルダ１０を簡単に取外すことができ、ケーブルホルダ１０を容易に交換することができると共に、太陽電池モジュール１のメンテナンス性を高めることができる。 Thus, according to the cable holder 10 of this embodiment, since the cable holder 10 is formed of a stainless steel wire, it is more resistant to environmental changes such as wind, rain, snow, and temperature as compared with conventional resin ones. The durability can be increased, and the labor involved in maintenance can be simplified. Moreover, the operator can move the pair of hanging parts 12 that hang down to the lower side of the extending piece 3c through the through-hole 3d of the frame 3 in the solar cell module 1 so that the operator can move the upper side of the extending piece 3c. Without turning the hand, the cable holder 10 can be easily removed from the lower side of the extension piece 3c, the cable holder 10 can be easily replaced, and the maintainability of the solar cell module 1 is improved. be able to.
　また、延出片３ｃの上面と当接する吊掛部１１と、貫通部３ｄの内壁と当接する垂下部１２と、延出片３ｃの下面と当接する当接部１６とを備えているので、吊掛部１１と垂下部１２と当接部１６とで貫通部３ｄを通して延出片３ｃを挟むように押えることができ、貫通部３ｃ内でケーブルホルダ１０がガタツクのを防止することができると共に、ケーブルホルダ１０が吊掛部１１を軸心として回動するのを抑制することができる。 Moreover, since the hanging part 11 which contacts the upper surface of the extension piece 3c, the hanging part 12 which contacts the inner wall of the penetration part 3d, and the contact part 16 which contacts the lower surface of the extension piece 3c are provided. The hanging part 11, the hanging part 12, and the contact part 16 can be pressed so as to sandwich the extending piece 3c through the through part 3d, and the cable holder 10 can be prevented from rattling in the through part 3c. The cable holder 10 can be prevented from rotating about the hanging portion 11 as an axis.
　また、上述したように、吊掛部１１を軸心としてケーブルホルダ１０が回動（揺動）するのを防止することができるので、ケーブルホルダ１０とフレーム３との間で摩擦が発生するのを可及的に抑制することができ、摩擦によってケーブルホルダ１０やフレーム３が摩耗して不具合が発生するのを防止することができると共に、ケーブルホルダ１０やフレーム３（太陽電池モジュール１）の耐久性を高めることができる。 Further, as described above, the cable holder 10 can be prevented from rotating (swinging) with the hanging portion 11 as an axis, so that friction is generated between the cable holder 10 and the frame 3. Can be suppressed as much as possible, and it is possible to prevent the cable holder 10 and the frame 3 from being worn out due to friction, and to prevent the occurrence of problems, and the durability of the cable holder 10 and the frame 3 (solar cell module 1). Can increase the sex.
　更に、一対のケーブル保持部１３によって配線ケーブル４を保持しているので、配線ケーブル４から荷重を一対の吊掛部１１へ略均等に作用させることができ、偏荷重によって線材からなるケーブルホルダ１０が歪んで不具合が発生するのを防止することができる。 Further, since the wiring cable 4 is held by the pair of cable holding portions 13, the load from the wiring cable 4 can be applied to the pair of hanging portions 11 substantially equally, and the cable holder 10 made of a wire material due to the unbalanced load. Can be prevented from being distorted and causing problems.
