  By the way, in addition to the 1st, 2nd waterproof outlet parts 7 and 8, you may enable it to attach another electric equipment to the mounting base part 6. FIG.

  For example, the mounting base 6 shown in FIG. 6 is formed in a hollow rectangular box shape similar to that shown in FIG. 4, but the length in the longitudinal direction (the left-right direction in FIG. 6A) is The length of the portions 70 and 80 is three times the length in the short direction. The mounting base portion 6 shown in FIG. 6 has three mounting portions 60 in order from one end side in the longitudinal direction (left end side in FIG. 6B). In the following description, in order to distinguish the three attachment parts 60, it represents with the code | symbol 60A-60C as needed.

  In the mounting base portion 6 shown in FIG. 6, the mounting portion 60 </ b> A is used for mounting the first waterproof outlet portion 7, and the mounting portion 60 </ b> B is used for mounting the second waterproof outlet portion 8. The attachment portion 60C is used for attachment of the leakage protection device 9. The mounting portion 60C has a pair of screw holes 6a as in the other mounting portions 60A and 60B, and the through hole 6b is also provided at an intermediate portion between the pair of screw holes 6a of the mounting portion 60C. Is formed.

  As shown in FIGS. 7A and 7B, the leakage protection device 9 includes a substantially fan-shaped vessel body 90 whose cross-sectional shape has a central angle of 90 degrees. A power supply side electric wire insertion hole (not shown) for the power supply line 200 and a load for the feed wiring are formed on the bottom surface (the lower surface in FIG. A side electric wire insertion hole (not shown) is provided. And in the container 90, the power supply side terminal (not shown) which contacts and holds the electric wire inserted from the power supply side electric wire insertion hole, and the load side terminal which contacts and holds the electric wire inserted from the load side electric wire insertion hole (Not shown) is housed, and an earth leakage interrupting mechanism (not shown) for interrupting an electric circuit between the power supply side terminal and the load side terminal when an electric leakage occurs is housed. Since such a leakage interrupting mechanism is well known in the art, a detailed description thereof will be omitted.

  Reference numeral 91 in FIG. 7 (a) denotes an operation lever for manual operation. When the electric circuit between the power supply side terminal and the load side terminal is interrupted by the above-described leakage interrupting mechanism, the lever is moved from the on position to the open position. Moved. Therefore, the energization between the power supply side terminal and the load side terminal can be started by moving the operation lever 91 from the open position to the closing position. Such an operation lever 91 protrudes outward from an opening 90b on the bottom surface of a recess 90a formed on the surface (front surface) of the container body 90 opposite to the mounting base 6 side. Therefore, the container body 90 is provided with a cover 92 that can open and close the recess 90a, thereby preventing rainwater and the like from entering the container body 90 through the opening 90b.

  When using such a leakage protection device 9, the power line 200 drawn into the mounting base 6 is connected to the first waterproof outlet portion 7 or the second waterproof outlet portion 8 via the leakage protection device 9. do it. If it does in this way, when electric leakage occurs in the 1st waterproof outlet part 7 or the 2nd waterproof outlet part 8, it will become possible to stop electric power feeding.

  The configuration of the waterproof outlet P of the first and second embodiments described above is merely an embodiment of the present invention, and is not intended to limit the technical scope of the present invention to the above example, but to the extent that does not depart from the spirit of the present invention. Can be changed.

It is a disassembled perspective view of the waterproof outlet apparatus of Embodiment 1. It is sectional drawing of the waterproof outlet apparatus same as the above. It is explanatory drawing of the usage example of the waterproof outlet apparatus same as the above. It is a disassembled perspective view of the waterproof outlet apparatus of Embodiment 2. The waterproof outlet apparatus same as the above is shown, (a) is a front view, (b) is a bottom view. The other example of a waterproof outlet apparatus same as the above is shown, (a) is a front view, (b) is a bottom view. The earth leakage protective device used for the above is shown, (a) is a perspective view with the cover open, and (b) is a perspective view with the cover closed.
