  In such a state of holding the tab 300, the tab 300 is sandwiched between the contact portion 221 of the guide frame 220 and the pressing portion 232 of the pressing member 230, and is elastic due to the elasticity of the pressing portion 232 of the pressing member 230. It is pressed against the contact part 221 of the guide frame 220.

  In this state, the pressing member 230 is configured such that the guide pin 231 provided on the pressing member 230 is provided with the lower end locking portion 2222 of the cam groove 222 provided on the guide frame 220 by the rearward bias of the pressing portion 232. The position is regulated by being locked to.

  In addition, when releasing the state of holding the tab 300, the pressing member 230 can be released by pulling up and down to the position shown in FIGS. Moreover, the state shown in FIGS. 26 to 30 can be repeated by positioning the pressing member 230 in the lower front direction.

  FIG. 31 is a longitudinal sectional perspective view of the state shown in FIGS. 27 to 30 with the lid 240 attached.

  The lid 240 is provided with a rubber packing 241 at the boundary between the solar module connection box 200 and the insulating housing 210, and waterproofness is imparted to the lid 240.

  According to the solar module connection box 200 of the second embodiment, when the solar module connection box 200 is connected to the tab 300 that is vertically raised from the solar panel from the direction opposite to the direction in which the tab 300 is raised. In addition, the position of the tab 300 with respect to the solar module connection box 200 is easily determined from above. Further, since the solar module connection box 200 is mounted horizontally with respect to the solar panel, the tab 300 can be held by a load from the vertical direction with respect to the solar panel, which is suitable for automation. Further, it is easy to confirm the holding state of the tab 300 from above, and it is possible to easily perform the release / re-hold operation. Further, the solar module connection box 200 of the second embodiment has a smaller number of parts than the solar module connection box 100 of the first embodiment described above.
