Description

  The present invention relates to an opening closing structure, an assembly of a solar cell module and a frame, and a seal member used for these.

In recent years, solar cells have been attracting attention due to increasing interest in environmental problems, and are installed in various building structures. The solar cell module is generally connected to a solar cell via a terminal box or the like, and has a connector that can be connected to another adjacent solar cell module or output circuit at the other end of the cable ( For example, Patent Documents 1 and 2).
Solar cell modules are used outdoors for a long period of time, and are required to have high reliability. In particular, a high waterproof property of a terminal box that is a cable lead-out portion is required.

  Patent Document 2 discloses a solar cell module in which a terminal box protruding below a solar cell is housed in a metal roof material. According to Patent Document 2, since the terminal box is housed in the metal roof material, the terminal box can be reliably waterproofed.

  Patent Document 3 discloses a rubber-like elastic body inserted in a hollow structure for inserting an output lead wire. Patent Document 3 describes that the inner diameter of the rubber-like elastic body inserted in the hollow structure must be smaller than the outer diameter of the output lead wire.

By making the cross section 44 of the opening portion of the guide portion 43 perpendicular to the axis of the holding hole 41, the cross sectional area of the opening portion can be minimized, and the water tightness is excellent.
Moreover, by having the guide part 43, the fixing property of the insertion member 300 is also excellent.

The cross section in the direction perpendicular to the axis of the holding hole 41 may be formed in the same shape as the cross section in the direction perpendicular to the axis of the elongated insertion member 300, and the shape is not particularly limited. A circular shape, an oval shape, various polygons, etc. are mentioned, These approximate shapes may be sufficient.
As shown in the example of FIG. 9, the inner surface of the holding hole 41 may be provided with a convex portion 45 at a part thereof. The convex portion 45 is provided in an annular shape in a direction perpendicular to the axis of the holding hole 41, and the cross-sectional inner diameter of the portion having the convex portion 45 is smaller than the outer diameter of the insertion member 300.

The insertion member is loaded in the holding hole,
The winding part is provided in the position of the upper surface side rather than the flange of the flange part of the said main body, The fastening member is wound around the said winding part, It is characterized by the above-mentioned.

The closing structure of the present invention will be described with reference to the drawings. FIG. 10 is a schematic view showing an embodiment of a closing structure according to the present invention. 10 shows an embodiment of the closing structure when the seal member main body of FIG. 1 is used, (A) is a plan view seen from the upper surface side of the seal member main body 100, and (B) is a front view. FIG. 11 shows an embodiment of a closing structure when the seal member main body of FIG. 7 is used. Moreover, FIG. 12 shows one Embodiment of the obstruction | occlusion structure at the time of using the sealing member main body of FIG.
As shown in the example of FIG. 10, the closing structure 400 of the present invention has a gap between the opening 102 provided in the flat plate-like structure 200 and the elongated insertion member 300 inserted through the opening 102. Is a closed structure in which the sealing member according to the present invention is closed, and the side surface 31 of the sealing portion 30 formed on the side surface of the sealing member main body 100 is a groove bottom portion and the flange lower surface 13 of the flange portion 10 and the omission The annular groove portion having the enlarged-side end surface 23 of the stopper portion 20 as the groove side surface and the opening portion 102 of the flat plate-like structure 200 are fitted, and the insertion member 300 is loaded in the holding hole 41 of the seal member main body 100. The fastening member 50 is wound around the winding portion 14 of the seal member main body 100.
In the closing structure 400 of the present invention, since the annular groove portion of the seal member body 100 and the opening portion 102 of the flat plate-like structure 200 are fitted, the gap between the opening portions 102 is closed. A holding hole 41 penetrating from the upper surface side to the lower surface side of the main body 100 holds the elongated insertion member inserted through the opening. Further, since the winding portion 14 of the main body 100 is tightened by winding the tightening member 50, the butted surfaces of the cuts 42 are brought into close contact with each other. As a result, the gap between the openings 102 of the planar structure 200 is completely closed, and water tightness is ensured. Further, since the seal member main body 100 and the insertion member 300 are in close contact with each other, even if the insertion member 300 is made of a flexible material that is not self-supporting, it can be fixed and prevented from being displaced.

Conventionally, when the insertion member is smaller than the opening, a method of sealing the gap between the opening and the insertion member using an epoxy resin or the like has been known. However, for example, when the gap is too large, such as when the diameter of the opening is twice or more the diameter of the insertion member, it is very difficult to ensure water tightness with the sealant.
By using the sealing member according to the present invention, the closing structure of the present invention provides a highly water-tight closing structure as described above. Therefore, even if the diameter of the opening is more than twice the diameter of the insertion member. Excellent waterproofness.

A member 202 having a size that can pass through the opening 102 of the cylindrical structure 200 is attached, and a member 203 having a size that cannot pass through the holding hole 41 of the main body 100 of the seal member is attached to the other end of the insertion member 300. Even if it is the insertion member 300 currently used, it can attach easily and watertightness and the fixing property of the insertion member 300 are ensured.

In the present invention, the flat plate structure 200 has sufficient rigidity so that the thickness of the flat plate 101 is substantially constant at least in a portion in contact with the seal member main body 100 and the closed structure is maintained.

The material of the flat plate 101 can be appropriately selected and used as long as the effects of the present invention are not impaired. Specific examples of the material include various metals such as iron, aluminum, and copper, glass, and a rigid resin.
What is necessary is just to adjust the thickness of the flat plate 101 suitably according to the use for which the said flat plate is used. The thickness is usually about 0.5 mm to 50 mm, and preferably 1 mm to 30 mm from the viewpoint of water tightness.
The shape of the opening 102 provided in the flat plate structure is not particularly limited, and can be an arbitrary shape depending on the application. For example, the shape may be a circle, an ellipse, various polygons, and the like. In the case of a polygon, it is preferably a substantially polygonal shape with corners subjected to R processing.

In the present invention, it is preferable that the elongated portion 201 of the elongated insertion member 300 has a substantially constant cross section from the viewpoint of excellent adhesion with the holding hole 41 and ensuring water tightness. Although the shape of the cross section of the elongate shape part 201 is not specifically limited, What has circular shape or an ellipse is preferable from a water-tight point.
The elongated portion 201 may be rigid, flexible, or flexible, may be a hollow transport tube, or may be a cable having a conducting wire or an optical fiber.
