Therefore, it is possible to improve water proofing property and the reliability of solar module 1.

< < second execution mode > >

As shown in Figure 6, the solar module 1 that relates to of the second execution mode the extension 15a and possessing of the side carrying cable 15 from solar battery panel 6 separate support component 26 between the back side 6b of solar battery panel 6 and cable 15 in different from the solar module that other execution modes relate to.

The extension 15a of the cable 15 of the side that support component 26 is opposed relative to the back side 6b with solar battery panel 6 has the carrier 26a of the concave shape consistent with its surface, therefore, the carrier 26a of support component 26 can support at the extension 15a of cable 15, can be separated between the back side 6b of solar battery panel 6 and cable 15.

According to the solar module 1 that the second execution mode relates to, be easily filled with a sealing parts 25 between solar battery panel 6 and cable 15.Further, the gap in the path becoming immersion can not be left at solar battery panel 6 and the close part of cable 15.

And then even if make cable 15 shake due to wind etc., support component 26 reliably carrying cable 15, therefore, it is possible to reduce the load putting on seal member 25, thus improves the water proofing property based on cover 21.

< < the 3rd execution mode > >

As shown in Figure 7, form the cover 21 of solar module 1 that the 3rd execution mode relates to resettlement section 23 inner side relative to cable 15 periphery from the direction that the length direction of cable 15 intersects has close protuberance 24 in different with the solar module that relates to of other execution mode.It should be noted that, " close protuberance " refers to the part close to cable 15 compared with other positions of the inner side of resettlement section 23.In addition, protuberance 24 can abut with cable 15, also can exist between protuberance 24 and cable 15 and be situated between at thing.

Such as, the position with the inner side of the resettlement section 23 of protuberance 24 becomes the slit of the U-shaped of diameter roughly the same with the external diameter of cable 15.Because protuberance 24 and cable 15 are close, in resettlement section 23, can the distance of cable 15 and resettlement section 23 be set to fixing, thus seal member 25 can be set to the thickness of expectation.

In addition, even if when cable 15 after solar module 1 is arranged shakes, the load of the seal member 25 of the inner side putting on body resettlement section 22 also can be reduced, thus cable 15 is suppressed to be peeled off with the bonding interface of seal member 25.Thereby, it is possible to the thickness of management seal member 25, there is no the state that rainwater is introduced with capillarity from the released part of above-mentioned bonding interface, thus the water proofing property based on cover 21 can be improved.

< < the 4th execution mode > >

It should be noted that, the height of above-mentioned rigidity such as, except from the difference of material is estimated, can measuring simply by the compression test etc. of the tension test of JIS K7161 or JIS K7181.

< < the 7th execution mode > >

As shown in Figure 11, the solar module 1 that relates to of the 7th execution mode in resettlement section 23 along with leaving housing 12 and different with the solar module that other execution modes relate to from the narrower intervals of cable 15.

Resettlement section 23 have be positioned at close to side, body resettlement section 22 the first resettlement section 23a be positioned at the second resettlement section 23b leaving the side of body resettlement section 22 compared with the first resettlement section 23a.Further, compared with the first resettlement section 23a, the interval of the cable 15 of the second resettlement section 23b and the inner side of resettlement section 23 is narrow.

Thus, even if when cable 15 shakes, the second resettlement section 23b reliably carrying cable 15, can suppress to be out of shape the seal member 25 reaching the inner side being positioned at the first resettlement section 23a.Consequently, the stripping of cable 15 and seal member 25 can be suppressed as far as possible, thus improve the water proofing property based on cover 21.

< < the 8th execution mode > >

As shown in Figure 12 A, Figure 12 B, the solar module 1 that 8th execution mode relates to is different from the solar module that other execution mode relates in the following areas, that is, there is in the body resettlement section 22 of cover 21 the first plug members 21b of the first peristome 21a and blocking the first peristome 21a.

There is in the upper surface side of body resettlement section 22 the first peristome 21a that can take out lid 13 size, and have for the tabular in approximate same size with the first peristome 21a and the first plug members 21b of the first peristome 21a can be blocked.First peristome 21a and the first plug members 21b such as can fix with the Qian He of screw or concaveconvex shape.

Thereby, it is possible to by seal member 25 at short notice efficiency be filled in well in cover 21, and seal member 25 densely can be filled to baroque bight, thus to improve operability.In addition, after the installation of cover 21, even if having the situations such as loose contact also easily to repair in the inner side of link box 11, thus the maintenance of solar module 1 management becomes simple.

It should be noted that, the first plug members 21b can have the seal member 25 and by bonding timber 21c of submerging at the interarea opposed with the first peristome 21a.Thus, the first plug members 21b is fixed at seal member 25, therefore, it is possible to omit for fixing the screw of the first plug members 21b or fitting portion etc. thus can making the simple structure of formation.

< < the 9th execution mode > >

As shown in Figure 13, the solar module 1 that relates to of the 9th execution mode the resettlement section 23 of cover 21 there is the second peristome 23c and have the second plug members 23d of blocking second peristome 23c in different from the solar module that other execution mode relates to.

Resettlement section 23 has the second peristome 23c of the box like of the parts 25 that can be filled with a sealing and can block the second plug members 23d of tabular of the second peristome 23c.The fixing of second peristome 23c and the second plug members 23d such as can be chimeric with the protuberance 23e of the side being arranged at the second peristome 23c and carry out with the suspension hook 23d1 of the side being arranged at the second plug members 23d.

So, the collecting body resettlement section 22 of link box 11 and the resettlement section 23 of carrying power cables 15 become different partitions, therefore when the bonding interface of cable 15 and seal 25 being soaked into immersion from outside, resettlement section 23 becomes cup, therefore, it is possible to improve the water proofing property of having accommodated the body resettlement section 22 of link box 11.

In addition, resettlement section 23 can confirm cable 15 from the second peristome 23c, densely seals around it, therefore, it is possible to the water proofing property of raising cover 21 with the mode seal member 25 of not leaving gap etc. on one side.

Other execution mode > > of < <

Above, the utility model does not limit above-mentioned execution mode, can apply more correction and change in the scope of utility model.

Such as, the hole portion of minor diameter can be set at cover 21.Thus, when having installed cover 21, being sealed in inner air and easily having departed from, thus the part 25 that can more densely be filled with a sealing.In addition, owing to the seal member 25 overflowed from cover 23 can be discharged from above described holes portion, therefore there is not seal member 25 and overflow in a large number from side, resettlement section 23 and the situation of outward appearance change grain.And then, can install in its hole portion and fasten.Thereby, it is possible to improve water proofing property to the immersion from hole portion.

It should be noted that, above-mentioned execution mode can be suitable for combining by the utility model.
