FIG. 1 is a development view showing a configuration of an embodiment of a packaging body for a solar cell module according to the present invention.

  The solar cell module packaging 10 includes a solar cell panel with a terminal box attached to the back surface, to which a cable having a connector provided at the tip is connected, and an outer peripheral portion of the solar cell panel. It is the packing body for packing the solar cell module containing the flame | frame with which it was mounted | worn. The package 10 for solar cell modules is sheet-like in the unfolded state, and is formed using, for example, cardboard. In the unfolded state, the solar cell module packaging 10 is connected to the side surface 2b, the bottom surface 3b, the inner side surface 4b, and the folded surface 5b via the creases D, E, F, and G along the top surface 1b. .

  Above the top surface 1b, an upper wall surface 1a (third side wall surface portion) having an upper insertion piece 1 is connected via a crease A. Below the top surface 1b, a lower side wall surface 4a (third side wall surface portion) having a lower insertion piece 4 is connected via a fold H.

  Above the side surface 2b, an upper wall surface 2a (second side wall surface portion) having an upper insertion piece 2 is connected via a crease B. A lower side wall surface 5a (second side wall surface portion) having a lower insertion piece 5 is connected to the lower side of the side surface 2b via a crease I.

  An upper wall surface 3a (first side wall surface portion) having an upper insertion portion 3 is connected to the upper surface of the bottom surface 3b through a crease C. Below the bottom surface 3b, a lower side wall surface 6a (first side wall surface portion) having a lower insertion portion 6 is connected via a crease J.

  The inner side surface 4b has a hole 11 and a notch 12 having a size suitable for the cable diameter. Here, a configuration is shown in which the cuts 12 are provided along the longitudinal direction of the inner side surface 4b, but the cuts 12 are provided along the short side direction or provided in a cross along both the long side direction and the short side direction. Also good.

  Since the overall shape of the solar cell module differs depending on the outer size of the solar cell module, the overall shape of the solar cell module packaging 10 is appropriately selected according to the outer size of the solar cell module. That is, the dimension of each part and those ratio are not limited to what was illustrated.

  The upper wall surface 3a and the lower wall surface 6a have recesses 3c and 6c in which the vicinity of the end on the tip side and one side in the lateral direction (right direction in FIG. 1) is cut out. The upper wall surfaces 1a, 2a and the lower wall surfaces 4a, 5a are notches 1g, 2g, 4g formed in a convex shape from one side to the other side so as to be confined between the base side and the tip side. 5g. The upper wall surfaces 1a, 2a and the lower wall surfaces 4a, 5a are related to the constricted portions of the notches 1g, 2g, 4g, 5g so that the recesses 3c, 6c straddle the upper wall surface 3a and the lower wall surface 6a on the front and back. Match.

  FIG. 2 is a diagram showing an assembling procedure of the solar cell module package. FIG. 2A is an enlarged front view around a corner showing a state where the upper wall surface is bent. FIG. 2B is an enlarged front view around a corner showing a state where the upper insertion piece is inserted into the upper insertion portion. FIG. 2C is an enlarged front view around the corner showing a state where the upper insertion piece is inserted into the upper insertion portion from between the upper wall surface and the upper wall surface. FIG. 2D is an enlarged front view around the corner showing a fixed state around the corner. In FIG. 2, these are shown separately in order to facilitate understanding of how the upper wall surfaces 1a, 2a, and 3a overlap, but as described above, these are part of one sheet-like member. is there.

  First, as shown in FIG. 2A, the bottom surface 3b is applied to the back surface near the long side surface of the solar cell module 20, and the upper wall surface 3a is applied to the short side surface and bent. Next, as shown in FIG. 2 (b), the upper insertion piece 2 is inserted into the upper insertion portion 3 while the side surface 2 b is applied to the long side surface of the solar cell module 20. Further, as shown in FIG. 2 (c), the upper insertion piece 1 is inserted between the upper wall surface 2a and the upper wall surface 3a while the top surface 1b is applied to the long side surface of the solar cell module 20. Plug in 3. By the above procedure, as shown in FIG. 2D, the periphery of the corner of the solar cell module package 10 is fixed, and the solar cell module 20 is easily and firmly held by the repulsive force of the cardboard.

  The bottom surface 3b, the side surface 2b, and the top surface 1b are bent, and the lower insertion pieces 4, 5 are inserted into the lower insertion portion 6 to assemble the solar cell module packaging body 10, and the lower side wall surfaces 4a, 5a, 6a. The procedure for covering and packing the corners of the solar cell module 20 is the same as the packing procedure described above.

  Next, the inner surface 4b and the folded surface 5b are bent. FIG. 3 is a diagram illustrating a state in which the inner surface and the folded surface are bent. The solar cell module 20 includes a solar cell panel 21 and a frame 30 attached to the periphery of the solar cell panel 21. The frame 30 includes a top flange 31 that contacts the light receiving surface of the solar cell panel 21, an inner flange 32 that contacts the back surface of the solar cell panel 21 and sandwiches the solar cell panel 21 between the top flange 31, and at the time of installation. A bottom flange 33 on the bottom side and a frame portion 34 that connects the top flange 31, the inner flange 32, and the bottom flange 33 are provided. The inner surface 4b of the solar cell module packaging 10 is bent toward the top surface 1b. The folded surface 5b is folded between the inner flange 32 and the bottom flange 33 as shown in FIG. Thus, when the inner side surface 4b is rotated around the corner 7a so that the angle formed by the inner side surface 4b and the bottom surface 3b is increased from the assembled state shown in FIG. 3, the folded surface 5b hits the frame 30. The movement of the inner side surface 4b is restricted. That is, the folded surface 5b has a function of preventing the inner side surface 4b from being separated from the frame 30, and maintains the solar cell module packaging 10 in an assembled state. By providing the projection 32a on the bottom surface side of the inner flange 32, the tip of the folded surface 5b is caught by the projection 32a and is difficult to come off, so the effect of maintaining the assembled state by the folded surface 5b is increased.

  4A and 4B are diagrams showing a procedure for fixing the cable / connector. FIG. 4A shows a state in the middle of inserting the connector 22 into the hole 11 and the notch 12, and FIG. 4B shows the hole 11 and the notch 12. Shows the state after the connector 22 is inserted. FIG. 5 is a cross-sectional view of the package for a solar cell module in a state where the cable and the connector are fixed. The connector 22 is inserted into the hole 11 and the notch 12, and the cable 23 and the connector 22 are fixed. The cable 23 and the connector 22 can be easily fixed to the solar cell module packaging body 10 by changing the positions and sizes of the holes 11 and the notches 12 according to the sizes of the cable 23 and the connector 22. As shown in FIG. 5, the cable 23 passes through the hole 11, but since the connector 22 is larger than the hole 11, the connector 22 cannot pass through the hole 12 unless force is applied to spread the notch 12. Therefore, the connector 22 passed through the hole 12 does not fall out of the hole 11 due to vibration during transportation.

  FIG. 6 is a view showing a state in which a solar cell module covered and packaged with a solar cell module packaging body is fastened with a polypropylene (polypropylene: PP) band. 6A is a perspective view from the light receiving surface (glass surface) of the solar cell module 20, and FIG. 6B is a perspective view from the back surface (back film surface) of the solar cell module 20. On the back surface of the solar cell panel 21, a terminal box 24 for attaching a cable 23 for taking out current to the outside and having a connector 22 provided at the tip is attached. By fastening the solar cell module 20 covered and packaged with the solar cell module package 10 with the polypropylene band 40, the solar cell module package 10 can be prevented from falling off the solar cell module 20.

  Since the solar cell module packaging body according to the present embodiment does not use an adhesive or an adhesive tape when packaging the solar cell module, it can be used repeatedly.

  In the above description, the solar cell module package 10 covers the entire long side surface of the solar cell module 20 as an example, but the solar cell module package 10 covers only the corners of the solar cell module 20. It is also possible to adopt a structure for packing and packing (a structure in which the first side wall surface portion is provided adjacent to only one of the bottom surface portions).

  According to the present embodiment, the cable 23 and the connector 22 can be fixed simply by inserting the connector 22 into the hole 11.

  As described above, the solar cell module packaging according to the present invention does not require the use of other parts such as tape for fixing the cable / connector, and the increase in cost can be suppressed and the cable / connector can be easily used. Therefore, it is useful in that it can prevent the connector portion from flapping during transportation and damaging the back film on the back surface of the solar cell module.
