Description

  The present invention relates to a connecting member of a solar cell module and a connecting structure of solar cell modules using the connecting member.

  As a structure for installing a solar cell module having the outer peripheral edge of a solar cell panel held by a frame on a roof, a structure using a long crosspiece is often used. As shown in FIG. 8, the frame body 50 that holds the outer peripheral edge of the solar cell panel P is fixed to a plurality of crosspieces 90 arranged in parallel to the roof surface via a fixing member 70. It is. Thereby, the solar cell module is fixed to the roof surface via the fixing member 70 and the crosspiece 90.

  However, among various members for installing the solar cell module on the roof, the crosspiece is a very expensive member. Usually, since two or more crosspieces are used to install one solar cell module, a very large number of crosspieces are necessary to install a large number of solar cell modules. There was a problem that increased. In addition, if a large number of long bars are installed on the roof, it will be quite heavy, so the roof may be reinforced in order to install the solar cell module. Met. Therefore, there has been a demand for a technique capable of reducing the number of crosspieces to be used and installing the solar cell module on the roof.

  Then, this invention makes it a subject to reduce the use number of crosspieces, and to install a solar cell module on a roof in view of said situation.

  In order to solve the above-mentioned problems, the connecting member of the solar cell module according to the present invention (hereinafter sometimes simply referred to as “connecting member”) includes “a flat bottom surface mounting portion and the bottom surface mounting portion. A lower end support member having a male screw portion protruding upward from the plate, a flat plate-like first base portion, a first leg portion extending downward from one end of the first base portion and standing on the bottom surface mounting portion A first standing wall portion standing upward from the other end of the first base portion, a first upper surface contact portion extending from the upper end of the first standing wall portion to the side opposite to the first base portion, and , And a first upper end holding member having a first through hole penetrating the first base portion and allowing the male screw portion to be inserted therethrough.

  The connection member of this configuration has a lower end support member that supports the lower end side of the frame body, and a first upper end holding member that holds the upper end side of the frame body, and the outer peripheral edge of the solar cell panel is the frame body. Two of the held solar cell modules can be connected on the end face side located on the same line.

  When using the connecting member of this configuration, the connecting member is disposed between the two frames that respectively hold the end faces located on the same line of the two adjacent solar cell panels, and the two frames are provided. Is mounted on the bottom surface mounting portion of the lower end support member. Next, the first upper end holding member is brought close to the lower end support member from above, the first upper surface contact portion is brought into contact with the upper surface portions of the two frame bodies, and the first standing wall portion is brought into contact with the side surfaces of the two frame bodies. Make contact. At the same time, the male screw portion protruding upward from the bottom surface placing portion is passed through the first through hole penetrating the first base portion, and the first leg portion is made to stand on the bottom surface placing portion.

  Then, a nut is screwed onto the male screw portion from above the first base portion, and the nut is tightened, whereby the first base portion is fastened to the bottom surface mounting portion by the male screw portion and the nut. Thereby, the force which presses two frames with respect to a bottom surface mounting part acts by the 1st upper surface contact part provided in a row by the 1st base part via the 1st standing wall part. At this time, since the first upper end holding member has the first leg portion, a gap exists between the first base portion and the bottom surface mounting portion by the height of the first leg portion. The first base portion is allowed to be elastically deformed so as to be bent by tightening the nut. As a result, the force with which the first upper surface contact portion presses the upper surface of the frame body becomes large, so that the two frame bodies are firmly held and connected by the first upper surface contact portion and the bottom surface mounting portion. The

  Therefore, according to the connection member having the above-described configuration, two frame bodies (in other words, two frame bodies positioned on the same line) respectively holding end surfaces positioned on the same line of the two solar cell panels are connected. Then, two solar cell modules can be connected. Thereby, the number of the crosspieces for fixing a solar cell module on a roof can be reduced, and a solar cell module can be installed on a roof. For example, if one solar cell module is fixed on the roof with one crosspiece, the fixing becomes unstable. On the other hand, two solar cell modules integrated by connection can be stably installed on the roof with a total of two crosspieces by fixing each on the roof with a single crosspiece. it can.

The connecting member 2 is disposed at a position between the two second frames 50b. Here, the second frame 50b has the same configuration as the first frame 50a, and both are distinguished only by the positional relationship with the connecting member 2.

  And the bottom face part 51 of the two 1st frame bodies 50a is mounted in the bottom face mounting part 11 of the lower end support member 10, and between 1st upper end holding member 20 and the lower end support member 10 similarly to 1st embodiment. The two first frame bodies 50a are sandwiched between them.

  Next, the two second frame bodies 50 b are placed on the bottom surface placing portion 11 on the same side as the side on which the first leg portion 25 stands with respect to the male screw portion 12. Thereby, the two second frame bodies 50b and the two first frame bodies 50a face each other on both sides of the male screw portion 12. When the second frame body 50b is placed on the bottom surface placing portion 11, the side surface portion 53 of the second frame body 50b is pressed against the stopper wall 17 erected from the bottom surface placing portion 11. The second frame body 50b can be positioned (see FIGS. 6A and 6B).

  Subsequently, the second upper end holding member 30 is brought close to the first upper end holding member 20 from above, the second upper surface abutting portion 34 is brought into contact with the upper surface portions 54 of the two second frame bodies 50b, and the second standing wall portion. 33 is brought into contact with the side surface portions 53 of the two second frame bodies 50b. At the same time, the male screw portion 12 that passes through the first nut 41 through the first through hole 22 of the first base portion 21 and protrudes further upward is used as the second through hole 32 that passes through the second base portion 31. The second leg 36 is made to stand on the second base 31. At this time, since the second leg locking groove 26 is formed in the first base 21, the second leg 36 is inserted into the end of the second base 31 by inserting the end of the second leg 36. Stand stably on top.

  Then, a second nut 42 is screwed onto the male screw portion 12 from above the second base portion 31, and the second nut 31 is tightened, so that the second base portion 31 is made first by the male screw portion 12 and the second nut 42. The second base portion 31 is fastened to the bottom surface mounting portion 11 via the first base portion 21. Thereby, the force which presses the two 2nd frame bodies 50b with respect to the bottom surface mounting part 11 by the 2nd upper surface contact part 34 provided in a row by the 2nd base part 31 via the 2nd standing wall part 33 is provided. Works. At this time, since the second upper end holding member 30 has the second leg portion 36, a gap exists between the second base portion 31 and the first base portion 21 by the height of the second leg portion 36. By this gap, interference between the first nut 41 and the second base portion 31 can be prevented. In addition, since the second base portion 31 is elastically deformed so as to bend by tightening the second nut 42 due to the presence of this gap, the second upper surface contact portion 34 presses the upper surface of the second frame 50b. Thus, the two frames are firmly held by the second upper surface contact portion 34 and the bottom surface mounting portion 11.
