The plurality of solar cells 11 housed in 25 and forming a solar cell module are sequentially connected in series. Thereby, when a load is connected between the first external connection terminal 31 and the second external connection terminal 32 led out of the insulating housing 22, the photovoltaic effect in each of the plurality of solar cells 11. The voltages generated by the above are added and supplied to the load.

  In the socket connector device 21 described above, the first conductive contact 26 attached to one of the plurality of cell receiving recesses 25 is connected to the other of the plurality of cell receiving recesses 25 adjacent to the one. 1 is provided with a conductive connecting member 33 that is connected to the second conductive contact 27 attached to one of the plurality of sockets. The socket connector device 21 shown in FIG. The first conductive contacts 26 attached to each of the cell accommodating recesses 25 and the second conductive contacts 27 attached to each of the plurality of cell accommodating portions 25 are connected to each other. It can also comprise as a thing provided with the electroconductive connection member. In that case, the first external connection terminal 31 and the second external connection terminal 32 are respectively led out from the first conductive contact 26 and the second conductive contact 27 attached to one cell housing portion 25. It is supposed to be.

  The first conductive contacts 26 attached to each of the plurality of cell receiving recesses 25 and the second conductive contacts 27 attached to each of the plurality of cell containing portions 25 are connected to each other. When the socket connector device 21 having the system conductive connection member is used, when the solar cell module is formed by accommodating the plurality of solar cells 11 in the plurality of cell accommodating recesses 25 in the same manner as described above, The plurality of solar cells 11 are connected in parallel. Thereby, when a load is connected between the first external connection terminal 31 and the second external connection terminal 32 led out of the insulating housing 22, the photovoltaic effect in each of the plurality of solar cells 11. The current based on the voltage generated by the above is added and supplied to the load.

The socket connector device according to the present invention as described above relates to the positive electrode terminal portion of one solar cell and the negative electrode terminal portion of another solar cell, or between the positive electrode terminal portions and the negative electrode terminal portions of a plurality of solar cells. With no need for soldering or welding using conductive wires, conductive ribbons, etc., and it is unnecessary to provide special members such as a substrate having a special three-dimensional structure, a plurality of solar cells, It can be widely applied to, for example, various electronic devices such as mobile phones, and the like that can be reliably positioned and held in a manner suitable for downsizing and thinning and can be connected in series or in parallel.
