As shown in the partial explanatory diagram of FIG. 7 and the overall explanatory diagram of FIG. 8, the electric wiring connecting the continuous solar cell modules has a large terminal box 101 connected to each solar cell module 100, and each solar cell module. The wiring 102 connected to the back surface of the solar cell module 100 and connected to the respective solar cell modules 100 is exposed in a complicated manner and is very unsightly from the room.

  Therefore, recently, a terminal that can be attached to the end of the solar cell module has been developed, and a structure in which a large terminal box cannot be seen from the room can be taken.

  However, although it is a small terminal, when it is attached to each solar cell module, the appearance is obstructed, and the wiring connecting the plurality of terminals cannot be prevented from being exposed in a complicated manner, and the state where the complicated wiring is visible from the room cannot be solved. There was a problem.

  Therefore, the present invention forms a latching portion of the conductive portion on one side of the solar cell module, attaches a terminal to the latching portion, and has a width for concealing the terminal at the joint of the continuous solar cell module. And a fixed locking portion that has a leg portion that is inserted into the joint at the inner center of the closing portion, and that is fixed to the end of the joint at the end of the joint. The terminal is concealed by attaching a joint gasket, and each wiring from each terminal is placed and guided in the joint gasket, and water-stopping pieces are provided on both sides of the body having a width covering the fixed locking portion, The fixed locking portion is covered with a cover having a locking projection for locking in a locking groove provided in the leg portion at the center.

  According to the present invention as described above, the engaging portion of the conductive portion is formed at one side end of the solar cell module, the terminal is attached to the engaging portion, and the joint gasket is attached to the joint of the continuous solar cell module. Since each wiring from each terminal was guided and guided, each terminal was concealed by the gasket, and each wiring from each terminal was concealed inside the joint gasket and attached to the wall of the curtain wall, etc. The solar cell module is excellent in appearance, and an effect that it is not unsightly when viewed from the inside is obtained.

  Moreover, since each terminal and each wiring are only concealed by the gasket attached to the joint, the attachment workability is excellent, and the maintenance and inspection are also provided.

  Embodiments according to the present invention will be described below with reference to the drawings.

Example 1
FIG. 1 is an explanatory diagram showing a terminal connection state, FIG. 2 is a partial explanatory diagram showing a wiring state of a solar cell module, FIG. 3 is an overall explanatory diagram showing a wiring state of the solar cell module, and FIG. 4 is an enlarged view showing a wiring state. In the figure, reference numeral 1 denotes a solar cell module, in which a locking portion 3 is formed on a conductive portion 2 on one side, and a terminal 4 is attached to the locking portion 3.

  As shown in FIG. 1, the state of the locking portion 3 of the terminal 4 is formed as a locking portion 3 by forming a stepped portion 6 having a width capable of installing the terminal 4 on the glass 5 of the conductive portion 2 of the solar cell module 1. It is attached so as to be installed on the stepped portion 6. In this way, the terminal 4 is accommodated within the thickness of the solar cell module 1, and the terminal 4 is attached so as not to protrude or slightly protrude from the surface of the solar cell module 1.

  Thus, each wiring 7 from the terminal 4 attached to each solar cell module 1 stores each wiring from the terminal 4 in a joint gasket 8 as shown in FIG.

  The joint gasket 8 has, for example, a width for concealing the attached terminal 4 as shown in the figure, and is inserted into the joint at the center of the closing portion 12 having the water stop pieces 11 formed on both sides and the closing portion 12. It has a structure in which a leg portion 13 is provided, and a fixed locking portion 14 is provided at an end portion of the leg portion 13 to be locked and fixed to the joint end.

  Furthermore, a cover 15 is provided to cover the fixed locking portion 14. The cover 15 has, for example, water-stopping pieces 16 on both sides of a main body having a width covering the fixed locking portion 14, and a locking protrusion 18 that locks in a locking groove 17 provided in the leg portion 13 in the center. It is a structure with

  In the above description, the locking portions 3 formed on each solar cell module 1 are formed facing each other with the joints interposed therebetween, and the terminals 4 are disposed opposite to each other.
