Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar cell module mounting base, and more particularly to a solar cell module mounting base suitable for mounting a solar cell module on a roof.

[0002]

2. Description of the Related Art When a solar cell module is mounted on a roof, a mounting base for the solar cell module is fixed to a support fitting mounted on a roof tile or a tile rod, and the solar cell module is mounted on the mounting base.

Then, a plurality of solar cell modules are connected by using an output cable or wiring material from the solar cell module or a connector for connecting these. Conventionally, the output cable, the wiring material, or the connector has been bundled with a binding material, and the wiring has been completed with this.

If the output cable, the wiring member, or the connector is used in this state, long-term repetitive external force such as wind sway may break the coating of the output cable, thereby deteriorating long-term reliability. .

In order to solve this problem, a method of passing these wiring members through the hollow internal space of the mounting base, providing a through hole perpendicular to the length direction of the mounting base, and passing an output cable or wiring material through the through hole. (JP-A-7-153985) and other improvements have been proposed.

[0006]

However, even in these improvement measures, it is necessary to provide through holes in the mounting base, and it is necessary to pass a wire or the like through the through holes on the roof, and to improve the mounting base. In the method of passing through the internal space, it is necessary to pass a wiring material inside the gantry while being fixed on the roof. These methods improve long-term reliability, such as prevention of disconnection of wiring materials, as compared with the conventional method of holding wiring materials using only a binding material, but significantly increase the cost in view of the required amount of work.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and has been made in consideration of the above problem. It is an object of the present invention to provide a place for accommodating a connector for connecting the above and to solve the above-mentioned conventional problems. Another object is to increase the strength of the mounting base at the same time.

[0008]

Means for Solving the Problems A solar cell module mounting base for fixing a mounting base to a support bracket and fixing a solar cell module to the mounting base. By providing a substantially L-shaped guide in which an output cable or connector of the solar cell module, a wiring member between the solar cell modules, or a wiring member for connection to a connection box or an inverter can be stored therein, Achieve the above objectives.

[0009] Further, a wiring member stopper for holding an output cable or a wiring member or a connector of the solar cell module housed in the substantially L-shaped guide is used.
The problem is further solved by making the width of the character-shaped guide not sufficiently larger than the diameter or width of the output cable or wiring member or connector of the solar cell module.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS As described above, an output cable or a wiring material or a connector for connecting a wiring material or the like is held by a binding material, a through-hole is provided in a mounting base, and the through-hole is passed through. By providing a substantially L-shaped guide along the length direction on the side surface or lower surface of this mounting base instead of passing through the internal space of the mounting base, and storing the output cable or wiring material or connector, it is easy and reliable. These output cables and the like can be fixed high. Since this substantially L-shaped guide can be produced simultaneously with the gantry by the embossing method for producing the gantry, there is no need to prepare a special groove material, and this can be achieved with a slight increase in cost. Then, the strength of the mounting base itself is increased by the substantially L-shaped guide.

In addition, a wiring member stopper for holding an output cable or a wiring member or a connector of the solar cell module housed in the substantially L-shaped guide is used.
By ensuring that the width of the character-shaped guide is not sufficiently wider than the diameter or width of the output cable or the wiring member or the connector of the solar cell module, it is possible to further securely fix.
