JPS6029753Y2 - Structure of resin substrate with solar cells attached - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to the structure of a resin substrate on which a solar cell is attached.

Generally, the voltage generated per chip of a solar cell is low, so by providing a plurality of solar cells and electrically connecting them in series, the voltage required by the load section is created.

As a structure for mounting this solar cell, it is known that the solar cell 10 is fixed on a printed circuit board 20 with solder as shown in FIG. The solar cells 10 cannot be easily replaced, and the current situation is to replace the entire board, which wastes other normal solar cells 10.

Furthermore, as shown in FIG. 2, there is a structure in which a solar cell 10 is fixed onto a substrate 20 with an adhesive and electrically connected to an adjacent solar cell 10 by bonding with a conductive member 30 such as a wire. The bonding process is extremely difficult, and there is a risk that the wires may be accidentally cut when handling the solar cells 10 that have been connected.

The present invention was developed in view of the above-mentioned problems, and instead of fixing the solar cell to the substrate with solder, adhesive, etc., a groove is provided on the side wall surface of the recess provided in the substrate, and a groove is provided around the recess. A part of the substrate is opened to pass through the edge of the substrate to form an inlet/outlet for the solar cells, and a plurality of solar cells are inserted into the groove through the inlet/outlet, and the solar cells are pressed by pressing the upper and lower surfaces of the groove. The present invention is characterized in that a battery is fixed in the recess, and an object of the present invention is to provide a structure in which the solar battery can be easily attached and detached.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

3a and 3b show an embodiment of the present invention, in which 10 is a solar cell having both positive and negative poles on its lower surface, and 20 is a resin parting plate having a parting window 21 in the center.

A recess 22 for housing the solar cell 10 is provided on both sides of the window 21 of the partition plate 20, and a groove 23 for fitting the solar cell 10 is formed in the side wall surface of the recess 22.

Further, a part of the periphery of the recess 22 is opened so as to pass through to the edge of the parting plate 20 to form an insertion/extraction opening 26 for the solar cell 10.

The lower surface of the groove 23 and the bottom surface of the recess 22 are on the same plane, and the recess 2
A wiring pattern for electrically connecting the solar cell 10 is provided on the bottom surface of the solar cell 2 .

The solar cell 10 is fitted into the groove 23 with the light-receiving surface facing upward, and is fixed by pressure applied to the upper and lower surfaces of the groove 23, and is electrically connected to the wiring pattern on the bottom surface of the recess 22.

Note that the solar cell 10 is attached and detached from the side of the parting plate 20.

In addition, as shown in figure b, there are several protrusions 2 on the wall surface of the groove 23.
4 to reduce the contact area, it becomes easier to slide the solar cell 10.

FIG. 4 shows another embodiment of the present invention, in which 10 is a solar cell;
20 is a resin dial plate having a solar cell window 25 on its upper surface.

Further, a recess 22 for housing the solar cell 10 is provided on the outer periphery of the lower surface of the dial 20, and a groove 23 for fitting the solar cell 10 is formed on the side wall surface of the recess 22.
A part of the periphery of the dial 20 is opened to pass through to the edge of the dial 20 to form an insertion/extraction opening 26 for the solar cell 10.

The solar cell 10 is inserted into the groove 23 through the insertion/removal port 26 as in the example shown in FIG. 3, and the light-receiving surface is exposed through the solar cell window 25.

Note that wiring of the solar cell 10 may be performed using the upper and lower surfaces of the groove 23.

FIG. 5 shows another embodiment of the present invention, in which 10 is a solar cell;
20 is a module substrate, and 30 is a conductive rubber.

A recess 22 for housing the solar cell 10 is provided on the upper surface of the module substrate 20, and a groove 23 for fitting the solar cell 10 is formed on the side wall surface of the recess 22.

In addition, a part of the periphery of the recess 22 is opened so as to pass through to the edge of the module substrate 20, and a slot 26 for inserting and removing the solar cell 10 is opened.
is formed.

The solar cell 10 is inserted through the slot 26 and fitted into the groove 23 via the conductive rubber 30.

The solar cell 10 is installed in the recess 2 as shown in FIG.
It may be performed from above 2.

As described above, the present invention has a structure in which the solar cell is inserted through the opening of the recess of the resin substrate and fitted into the groove provided on the side wall of the recess, making it easy to attach and remove the solar cell and replace it without soldering. This has the advantage that unnecessary work such as gluing can be omitted.
