By holding the ground terminal 502 between the plate portion 132a and the strip plate portion 132b and the protruding portion 320 and inserting the ground terminal 502 as shown in FIG. 8, the ground terminal 502 becomes the strip plate portion 132a and the strip plate portion. It fits between 132b and the protrusion part 320 (refer FIG. 9). In addition, since the step portion 324b and the second lateral portion 324c are provided, the ground terminal 502 is not easily detached. When the ground terminal 502 is locked to the locking portion 304, the second lateral portion 324 c is located in the opening 502 a of the ground terminal 502.

  In addition, the structure of the latching | locking parts 302 and 304 is good also as a structure shown in FIG. That is, since the latching portion 302 and the latching portion 304 are symmetric, the side portion on the back side of the band plate portion 132a is divided into a side portion in the left-right direction and a side portion in the front-rear direction.

Thereafter, the crosspiece 40 of the roof tile 1b to be constructed adjacent to the left side of the roof tile 1a is put on the insertion portion 30 of the roof tile 1a, and the nail is inserted into the nail holes 60a and 60b of the roof tile 1b, and the crosspiece 310a. The roof tile 1b is constructed by hitting it. The above steps are repeated to construct the roof tile 1 in the girder direction. In the above description, the roof tile is sequentially constructed on the left side of the constructed roof tile. However, the roof tile may be constructed in the opposite direction, and the roof tile 1 constructed on the right side of the constructed roof tile 1 may be used. The roof tiles may be sequentially constructed so that the insertion part 30 is inserted into the crosspiece 40 of the roof tile 1 that has already been constructed.

  Next, when constructing the roof tile 1 to be constructed on the bottom side of the constructed roof tile 1, the construction is performed by engaging the latching protrusion 58 with the latched portion 36 of the insertion portion 30 of the roof tile 1. I will do it. For example, when the roof tile 1c in FIG. 19 is constructed, the locked portion 36 is locked to the locking protrusion 58 of the roof tile 1b located diagonally lower left, and the nail holes 60a and 60b are inserted into the pier 310b. The nails are driven in and installed. Then, the roof tile 1d is constructed adjacent to the left side of the roof tile 1c. That is, the locked portion 36 of the roof tile 1d is locked to the locking protrusion 58 of the roof tile 1b located obliquely at the lower left, and the crosspiece 40 of the roof tile 1d is covered with the insertion portion 30 of the roof tile 1c. The nails are inserted into the nail holes 60a and 60b of the roof tile 1d, and the nail is driven into the pier 310b. The above steps are repeated to construct roof tiles in the direction of the roof tile 1c. Similarly to the above, a roof tile may be constructed on the right side of the constructed roof tile.

  As described above, the construction of the roof tile 1 in the girder direction is performed sequentially from the eave side (R1 side in FIG. 19) to the ridge side (R2 side in FIG. 19) in the flow direction, and as shown in FIG. 1 is constructed.

  Next, the connecting metal fitting 101 is attached to each roof tile 1 constructed on the roof surface. That is, the front side of the connecting metal fitting 101 is the head 14 side of the roof tile 1, and the locking projection 16 is inserted into the opening 112 a of the connecting metal fitting 101, and the distal end portion 114 b of the elastic portion 114 and the distal end portion of the elastic portion 116 are inserted. In a state where 116 b is in contact with the upper surface of the roof tile 1, the connecting metal fitting 101 is pressed toward the roof tile 1, and the bottom plate portion 111 is in contact with the upper surface portion 18 a of the protruding portion 18 and the upper surface portion 20 a of the protruding portion 20. By setting the state, the elastic portions 114 and 116 are rotated upward to reach the state shown in FIG. That is, the elastic portion 114 protrudes upward from the opening 112b, and the elastic portion 116 protrudes upward from the opening 112c. In this state, the front end portion 114b is on the back side of the groove portion 18f and is in contact with the back surface portion 18e of the projecting portion 18, and the front end portion 116b is on the back side of the groove portion 20f and the back surface of the projecting portion 20 is reached. It will be in the state which contact | connected the part 20e.

  Then, by sliding the connecting metal fitting 101 to the head side of the roof tile 1, the edge 113 on the back side of the opening 112a enters the notch 16f of the locking projection 16, and is shown in FIG. It becomes a state.

  Thereafter, the connecting metal fitting 101 is further slid to the head side of the roof tile 1 so that the tip end portion 114b of the elastic portion 114 is fitted into the groove portion 18f and the tip portion 116b of the elastic portion 116 is fitted into the groove portion 20f. Thus, the state shown in FIG.

  In the state in which the tip end portion 114b is fitted in the groove portion 18f and the tip end portion 116b is fitted in the groove portion 20f, the edge portion 113 on the back side of the opening portion 112a is connected to the back portion (the end portion on the front side) of the notch portion 16f. ) And the bottom plate portion 111 is locked to the locking protrusion 16. As described above, the connecting metal fitting 101 is attached to the roof tile 1 by being locked and fixed to the roof tile 1. Here, “locking / fixing” means that, as shown in FIG. 20 (b), after the edge 113 of the connecting metal fitting 101 is locked to the locking protrusion 16, the tip 114 b is fitted into the groove 18 f. At the same time, the fitting portion 101 is fixed to the roof tile 1 by fitting the front end portion 116b into the groove portion 20f. When the connecting metal fitting 101 is attached to the roof tile 1, the state shown in FIG.

  In addition, in the state which attached the connection metal fitting 101 to the roof tile 1, as shown in FIG.20 (c), the edge part of the front side (eave side) of the connection metal fitting 101 and the front side (eave side) of the roof tile 1 are shown. The end portion is at substantially the same position in the flow direction. 20 and 22, the connecting metal fitting 101 is drawn with the cutout parts KB1 and KB2 and the protruding part 320 omitted.

  When attaching the connecting metal fitting 101, it may be attached to a predetermined roof tile 1 so that two connecting metal fittings 101 are attached to one solar cell module 201, but the connecting metal fitting 101 engaged with the solar cell module 201 is attached. It is preferable to attach the connecting metal fittings 101 to all the roof tiles 1 in order to increase the number of the roof tiles and to reliably perform the construction on the roof surface.

  Next, the solar cell module 201 is attached to the connecting metal fitting 101 attached to the roof tile 1. In the solar cell module 201, which of the long side part 222a and the long side part 222b is the eaves side, as will be described later, the long side part 222a side and the long side part 222b side alternately in the flow direction. Is the eaves side.

  First, a method for attaching the solar cell module 201 to the connection fitting 101 will be described. In FIG. 22, the solar cell module to be attached is a solar cell module 201a, the solar cell module installed on the ridge side of the solar cell module 201a to be attached is a solar cell module 201b, and the solar cell module 201a is attached. The connecting bracket is referred to as a connecting bracket 101a, and the connecting bracket to which the solar cell module 201b is attached is referred to as a connecting bracket 101b.

  First, as shown to Fig.22 (a), the eaves side (long side part 222a side) with respect to the ridge side (long side part 222b side) with respect to the installation direction of the original solar cell module 201a as for the solar cell module 201a. In this state, the ridge side of the solar cell module 201a is inserted into the gap between the connection fitting 101a (connection fitting for attaching the solar cell module 201) and the solar cell module 201b provided adjacent to the ridge side. The claw portion 234b of the metal fitting engaging portion 234 of the long side portion 222b is engaged with the engaging portion 154 of the connecting metal fitting 101a. When the claw portion 234b of the metal fitting engaging portion 234 of the long side portion 222b is engaged with the engaging portion 154 of the connecting metal fitting 101a, in this state, the connector 217 is connected to the adjacent connector 219, and the connector 219 is adjoined. Connected to the connection fitting 101 of the solar cell module 210 to be connected. Details will be described later.

  Then, as shown in FIG.22 (b), the eaves side of the solar cell module 201a is rotated below. That is, the solar cell module 201a is rotated downward around the engaging portion of the claw portion 234b and the locking portion 154. In addition, since the roof tile 1 and the connecting metal fitting 101a are inclined on the roof surface, when the solar cell module 201a is rotated downward, the solar cell module 201a is also inclined toward the eaves side, and the solar cell module 201a. The engagement between the locking portion 154 and the claw portion 234b is strengthened by its own weight.

  Thereafter, as shown in FIG. 22 (c), the claw portion 234b of the metal fitting locking portion 234 of the long side portion 222a contacts the front end plate portion 142c of the side wall portion 140, so that the eave side of the solar cell module 201a is pushed downward. Then, the claw portion 234b is guided by the outer surface of the tip plate portion 142c and slides downward.

  Thereafter, the claw portion 234b of the metal fitting engaging portion 234 of the long side portion 222a is engaged with the engaging portion 144, and the state shown in FIG.

  As described above, the solar cell module 201 is locked to and fixed to the connecting metal fitting 101 to be attached to the connecting metal fitting 101, and the solar cell module 201 is supported by the connecting metal fitting 101. Here, “locking / fixing” means, as shown in FIG. 22A, after the claw portion 234b of the long side portion 222b is locked to the locking portion 154, the claw portion 234b of the long side portion 222a. Means that the solar cell module 201 is fixed to the connection fitting 101 by being locked to the locking portion 144. In the state where the solar cell module 201 is attached to the connecting metal fitting 101, the state shown in FIG.

  In FIG. 22, the roof tile 1 a and the connecting metal fitting 101 a are actually shifted from the roof tile 1 b and the connecting metal fitting 101 b in the girder direction (rightward as viewed from the eaves side) as shown in FIG. 19. In FIG. 22, the cutting line for the roof tile 1a and the connecting fitting 101a and the cutting line for the roof tile 1b and the connecting fitting 101b are shifted in the digit direction. That is, the roof tiles are so-called staggered that are constructed with a roof tile that is adjacent in the flow direction being shifted by a half of the working width of the roof tile.

  Since the length of the cable 216 and the length of the cable 218 are different as described above, one of the long side portion 222a and the long side portion 222b of the solar cell module 201 and the other are alternately arranged in the flow direction. In the solar cell module 201 installed in the flow direction, the short side portions can be aligned and installed by using the eaves side.

  That is, as shown in FIG. 23, in the solar cell module 201-3 on the ridge side in the flow direction, the long side portion 222b is the eave side, and the solar cell module 201- adjacent to the eave side of the solar cell module 201-3. 2, the long side portion 222a side is the eave side, and in the solar cell module 201-1 adjacent to the eave side of the solar cell module 201-2, the long side portion 222b side is the eave side.

  Also, each of the solar cell modules 201-1 to 201-3 is connected to four connecting fittings 101 (connecting fittings attached to the four roof tiles 101 arranged continuously in the girder direction). It is attached. In addition, all the connection fittings 101 attached to the roof tile shall be attached to any of the solar cell modules 201, and all the connection fittings 101 are also provided in the plurality of connection fittings 101 provided in the girder direction. It shall be attached to any solar cell module 201. And in the solar cell module 201-1 and the solar cell module 201-3, in the solar cell module 201-2, the length L21 between the center position of the rightmost connecting fitting 101 and the outer end of the short side portion 224a, The center position of the leftmost connecting fitting 101 and the length L22 between the outer end portions of the short side portion 224a are the same (may be substantially the same), so that the solar cell modules 201-1 to 201-201. The position of each short side portion of -3 in the digit direction can be matched.

  The vertical direction of the solar cell module at each position in the flow direction is the same direction. For example, the solar cell module applied in the beam direction of the solar cell module 201-1 is similar to the solar cell module 201-1. On the other hand, the solar cell module applied in the girder direction of the solar cell module 201-2 is applied with the long side portion 222b as the upper side, similarly to the solar cell module 201-2. In a plurality of solar cell modules connected in the flow direction, construction is performed in order from the eaves side.

  And in the predetermined position in a flow direction, the solar cell module 201 is sequentially constructed in the direction in which the connector (female connector) 219 protrudes from the solar cell module 201. That is, when a certain solar cell module 201 is constructed, the connector 219 is exposed from the lower position of the solar cell module 201, and is attached to the four connection fittings 101, and then the connector 219 is adjacent to the adjacent solar cell. It attaches to the connection metal fitting 101 nearest to the solar cell module 201 among the connection metal fittings 101 to which the module 201 is attached. For example, in the example of the solar cell module 201-1 in FIG. 23, the connector 219 is a connection fitting (first proximity connector) 101-5 to which a solar cell module (first adjacent solar cell module) adjacent to the X1 side is attached. Attach to. When the connector 219 is attached to the connection fitting 101, the connector 219 is attached so that the tip of the connector 219 faces the outside of the connection fitting 101. For example, when attaching the connector 219 of the solar cell module 201-1 to the connection fitting 101-5, it is attached to the locking portion 370 of the side wall portion 130 of the connection fitting 101-5. In addition, in the state which inclined the solar cell module 201-1 in the attachment position (state of the solar cell module 201a of Fig.22 (a)), the connector 219 is attached to the connection metal fitting 101, and solar cell module 201-1 after that. May be attached to the four connecting fittings 101.

  Thereafter, the solar cell module 201 provided with the connector 217 to be connected to the connector 219 (that is, the solar cell module to be constructed adjacent to the connector 219 side in the digit direction) is inclined at the mounting position (FIG. 22A). The solar cell module 201a), the connector 217 is connected to the connector 219. For example, when the solar cell module 20-1 in FIG. 23 is the solar cell module 201-21 in FIG. 24 and the solar cell module 201-11 is installed next to the solar cell module 201-21, the solar cell module 201- The connector 217 is connected to the connector 219 of the solar cell module 201-12 (the connector 219 is attached to the connecting metal fitting 101) in a state where 11 is inclined. In the state of the solar cell module 201a in FIG. 22A, the connector 219 is drawn out to a position exposed from the lower position of the solar cell module 201. The above operation is repeated to install the solar cell module 201 in the girder direction.

  Next, when constructing the solar cell module 201 adjacent to the eaves side, in the solar cell module 201 constructed adjacent to the ridge side, the connector 219 drawn to the outside is connected to the nearest coupling metal fitting 101. Install. In FIG. 23, in the case of the solar cell module applied to the end portion on the X1 side among the plurality of solar cell modules in which the solar cell modules 201-1 to 201-3 are applied in the digit direction, the solar cell module 201- The third connector 219 is attached to the connecting bracket 101-14 with the tip of the connector 219 protruding to the X2 side. That is, it attaches to the latching | locking part 360 of the side wall part 120 of the right side surface side of the connection metal fitting 101. FIG. And the solar cell module 201-2 is made into the state of the solar cell module 201a of Fig.22 (a), and the connector 217 of the solar cell module 201-2 is connected with the connector 219 attached to the connection metal fitting 101-14. Thereafter, the solar cell module 201 is constructed in the same manner as described above, but the solar cell modules 201 are sequentially constructed in the X2 direction at the position of the solar cell module 201-2. As described above, in the connector 219 and the connector 217, the connector 219 is attached to the coupling metal 101 (that is, the connector provided on the longer cable of the pair of cables). It connects to a connector 219 attached to 101.

  For example, as shown in FIG. 24, when constructing three solar cell modules in three rows in the flow direction and in the digit direction, the long side 222a side of the solar cell module on the most ridge side is the ridge side, The solar cell modules 201-33, 201-23, 201-13, 201-12, 201-22, 201-32, 201-31, 201-21, 201-11 will be applied in this order. And each cable 216,218 in a solar cell module meanders from the solar cell module 201-33 to the solar cell module 201-11 in series, as shown in FIG. Link.

  When the solar cell module 201 is attached to the connecting metal fitting 101, a gap is formed between the strip plate portions 122 and 132 and the bottom surface of the module main body 212, so that the connector 219 is directly below the frame 220 or the terminal box. Since it is not provided directly under 214, the connector 219 attached to the connection fitting 101 does not hinder the construction of the solar cell module 201.

  As the ground terminal 502, a ground wire having the ground terminal 502 attached to both ends of the cable 500 (see FIG. 8) is used, but at least one of the four connecting fittings 101 to which one solar cell module 201 is attached. One earth terminal 502 is attached to one, and the other earth terminal 502 is attached to at least one of the four connecting fittings 101 to which the other solar cell module 201 is attached. That is, since the frame 220 of the solar cell module 201 is made of metal, if the ground terminal 502 is connected to any one of the four connection fittings 101, the frame 220 and the other three connection fittings 101 are electrically connected. Connected. Then, an earth wire is attached between adjacent solar cell modules 201 to ground one earth wire. For example, in the example of FIG. 24, between the solar cell module 201-13 and the solar cell module 201-23, between the solar cell module 201-23 and the solar cell module 201-33, and between the solar cell module 201-12 and the solar cell module 201-. 22 between the solar cell module 201-22 and the solar cell module 201-32, between the solar cell module 201-11 and the solar cell module 201-21, and between the solar cell module 201-21 and the solar cell module 201-31. In addition, a ground wire is attached between the solar cell module 201-33 and the solar cell module 201-32, and between the solar cell module 201-32 and the solar cell module 201-31, and from the solar cell module 201-31 to the ground. Ground.

  Such attachment of the ground wire (that is, attachment of the ground terminal 502) may be performed in a state where the connection fitting 101 is applied to the roof tile 1, or when the solar cell module 201 is applied, FIG. ) In the state of the solar cell module 201a.

  In FIG. 23, in order to make the drawing easy to see, the module main body 212 and the frame 220 are drawn by an alternate long and short dash line, and the substantially square portion in the solar cell module 210-1 shows the outline of each cell. Yes.

  As described above, in the connection fitting 101 of the present embodiment, the locking portions 360 and 370 for attaching the connectors 219 and 217 are provided, so that the connectors 219 and 217 (particularly the connector 219) are connected to the connection fitting 101. Since the connectors 219 and 217 can be fixed at predetermined positions (that is, the positions of the locking portion 360 and the locking portion 370) of the coupling fitting 101, the connector 219 can be fixed to the locking portion 360 (or the engagement portion). By fixing to the stopper 370), the connector 217 can be easily connected, and the solar cell module 201 can be easily constructed.

  Further, unlike the case of the connecting metal fitting shown in Japanese Patent Application Laid-Open No. 2006-125084, the cable is not damaged because it is not a structure for fixing the cable. Further, even if the connector 219 (217) is attached to the locking portion 360 or the locking portion 370, the solar cell module 201 is not contacted when the solar cell module 201 is constructed (in particular, the frame 220 and the terminal box 214 are not connected). Connector 219, 217 does not become a hindrance when constructing solar cell module 201.

  Moreover, in the connection metal fitting 101 of the present embodiment, since the engaging portions 302 and 304 for attaching the earth terminal 502 are provided, the earth wire can be easily attached between the solar cell modules, and as a result The solar cell module 201 can be easily constructed.

  In particular, in the case of Japanese Patent Application Laid-Open No. 2006-57321, a protective plate (decorative plate) is provided so as to be electrically connected between solar cell panels adjacent to each other in the girder direction. In this embodiment, the grounding terminal 502 is attached to the connecting metal fitting 101 so that the grounding terminal 502 is inserted into the engaging portions 302 and 304. In addition, since the ground wire can be attached between the solar cell modules adjacent to each other in the beam direction and between the solar cell modules adjacent to each other in the flow direction, the grounding can be easily performed.

  Further, in the solar cell module 201 of the present embodiment, the lengths of the pair of cables 216 and 218 are different, and the longer cable 218 protrudes from the short side portion 224b of the solar cell module 201 in plan view. Then, after attaching the connector 219 at the tip of the cable 218 to the connecting metal fitting 101 of the adjacent solar cell module 201, the operation of connecting the connector 217 of the adjacent solar cell module 201 to the connector 219 is repeated in the direction of the connector 219. Since construction is performed in the girder direction, wiring of the cables 216 and 218 is facilitated, and the solar cell module 201 can be easily constructed.

  Further, the lengths of the pair of cables 216 and 218 are different from each other, and the solar cell modules 201 are installed adjacent to each other in the flow direction so that the long side portion 222a side and the long side portion 222b side are alternately set in the flow direction. The positions of the short sides of the solar cell modules 201 to be aligned can be aligned, and the appearance can be improved when a plurality of solar cell modules 201 are constructed. That is, as shown in FIG. 19, the roof tile 1 is provided so as to be shifted in the girder direction with respect to the roof tile 1 adjacent in the flow direction, so the connecting metal fitting 101 is also attached to the roof tile 1 adjacent in the flow direction. In the case where the pair of cables in the solar cell module 201 have the same length (referred to as a solar cell module 201 ′) provided to be shifted in the digit direction with respect to the connecting metal fitting 101, normally, as shown in FIG. As shown in the figure, the solar cell modules 201 ′ adjacent to each other in the flow direction are shifted in the spar direction, and when trying to align the positions of the short sides in the spar direction, the lengths of the pair of cables are It is necessary to keep the length of the battery module 201 ′ so that it protrudes from the short side of the battery module 201 ′, the cable length is excessive, and there is an extra length of cable (that is, the pair of cables is short). Because it is so long that it protrudes from the part, the length that is twice as long as it protrudes becomes extra), so it is necessary to arrange the cable for the extra length, and it is not easy to install the solar cell module However, in this embodiment, there is no extra length cable (or the extra length cable can be reduced as much as possible), and the solar cell module 201 can be easily installed. . Since the position of the short side portion of the solar cell module 201 adjacent to the flow direction can be aligned, when constructing the solar cell module, it is sufficient to align the position of the short side portion of the beam direction, A solar cell module can be easily constructed.

  In the above description, the connector (male connector) 217 is provided in the cable 216 and the connector (female connector) 219 is provided in the cable 218. However, the connector (female connector) 219 is provided in the cable 216, and the cable 218 is provided. A connector (male connector) 218 may be provided. In that case, the connector 217 provided on the longer cable 218 of the pair of cables is attached to the connection fitting 101, and the connector 219 is connected to the connector 217 attached to the connection fitting 101.
