Description

[Detailed description of the invention] The present invention relates to solar cell collectors.

In general, solar cell collectors generate electricity using solar energy, and are widely used as a means of energy management today.

As shown in Figures 1 and 2, a conventional solar cell collector 1 has multiple collectors (two in this figure) located in the center of a transparent outer case 2.
solar cell elements 3, 3 are provided, and the solar cell elements 3, 3 are provided.
A transparent resin 4 is filled and solidified between the outer case 2 and the outer case 2, and each solar cell element 3 is connected in series with all conductor wires 5, and the positive potential of the electromotive force generated by each solar cell element 3 A positive side connection terminal 6 for taking out the message and a negative side connection terminal 7 for taking out the negative message are formed to protrude from the lower surface of the outer case 2.

However, the conventional solar cell collector 1 described above has the following disadvantages when a large number of solar cell collectors are connected to obtain a large electromotive force.

That is, each connection terminal 6 of a large number of solar cell collectors 1,
7 in series or in parallel, the connection terminals 6 and 7 are structured to protrude from the bottom surface of the outer case 2, so the connection must be completely insulated after the connection operation.

Conventionally, this insulation was achieved by coating the connection part with an insulating adhesive tape, or by applying an insulating agent containing a hardening accelerator in the gold base with a brush, or coating the connection part with an insulating adhesive tape. The parts had to be insulated by immersing them in an insulating agent. This insulation work is troublesome and requires a long time.

In order to eliminate this inconvenience, conventionally, as shown in FIGS. 3 and 4, step portions 8 a and 8 bl are formed in vertically opposite directions at both ends of the solar cell collector 1 in the longitudinal direction, and these step portions 8 a and 8 b are formed. A positive electrode side connection terminal 6 and a negative electrode side connection terminal 7 are provided on the inner surface of the solar cell collector 1 so as to protrude from each other, and the step portions 8a and 8b of adjacent solar cell collectors 1 are stacked on top of each other so that each connection terminal 6 and 7 is tightly attached. The bolt 9 and the nut 10 were formed so as to be tightened and connected.

However, although it is possible to connect multiple solar cell collectors 1 in a straight line in the conventional solar cell collector 1 shown in FIGS. The connection terminals 6 and 7 of the solar cell connector 11 located at the bottom must be connected with a conductive wire. Also,
Rainwater enters between each step 8a and 8b, and each connection terminal 6, 7
There is a risk of inducing poor connection. In addition, it takes a long time to tighten the nuts 9 and 10 to connect the solar cell collectors 1 and 1, and it also takes a long time. It is also necessary to waterproof the nuts and bolts, and what's more? There was an inconvenience that the nuts and nuts protruded from the upper and lower surfaces of the solar cell collector 1, making it difficult to attach the mounting tools.

The present invention has been made in view of these points, and it is possible to perform various wirings (for example, straight wiring, zigzag wiring, etc.) with one type of solar cell collector, and has excellent productivity. The object of the present invention is to provide a solar cell collector that is easy to connect each solar cell collector and has excellent waterproof properties.

This purpose is to provide an outer case, a solar cell element housed inside the outer case and generating an electromotive force, a positive electrode side connection terminal for the electromotive force provided for deriving the electromotive force, and a negative electrode side. In the solar cell collector having a connection terminal, the side part of the outer case has a rectangular side member.
