The recessed portion 16 is in an attached state and is separated from the construction surface 1, and can accommodate the flange portion 12 of the waterproof bushing 7.

  An insertion port 17 is formed at a position substantially opposite to the tube portion 11 at the approximate center of the recess 16. The insertion port 17 is an oblong shape that is long in the vertical direction, and a rib 18 that protrudes toward the flange portion 12 is formed on the entire periphery of the insertion port 17.

  A slit 19 for projecting the upper end of the flange 12 of the waterproof bushing 7 upward is formed above the recess 16 in the waterproof packing 9.

  Further, a drainage groove 20 (see FIGS. 4 and 5) penetrating vertically in a state communicating with the recess 16 is formed in a portion below the recess 16 in the waterproof packing 9.

  Furthermore, fixing holes 21 corresponding to the fixing holes 5 of the construction surface 1 are formed above and below the recess 16 of the waterproof packing 9.

  Next, the structure of the rainproof cover main body 10 will be described.

  The rainproof cover main body 10 is made of a synthetic resin and includes a body 22 and a cover 23.

  The body 22 has the same rectangular shape as that of the waterproof packing 9, and a concave portion 24 that accommodates the concave portion 16 of the waterproof packing 9 is formed from the back side in the center of the upper and lower sides, and the insertion opening 17 of the waterproof packing 9 is formed in the center of the concave portion 24. The insertion opening 25 having the same shape as that of the first embodiment is formed.

  Fixing holes 26 corresponding to the fixing holes 21 of the waterproof packing 9 are formed above and below the recess 24.

  Protrusions (locking portions) 27 that are engaged in the circumferential grooves 15 of the waterproof packing 9 are formed on substantially the entire periphery of the periphery of the body 22.

  And from the side end and lower end of the body 22, the side part 28 and the bottom face part 29 are integrally formed toward the outdoor side, respectively.

  A pair of upper and lower guide grooves 30 are recessed in the outer surface of the side surface 28. The guide grooves 30 are basically formed along the horizontal direction, and the outdoor side of each guide groove 30 has a taper shape extending in the vertical direction. And in the outdoor side part of these guide grooves 30, the taper part of the upper and lower guide grooves 30 is integrated and it is in the state integrated.

  Locking grooves 31 are formed downward from the guide groove 30 at the base end portion of the side surface portion 28 with respect to the body 22 at the indoor side end of the guide groove 30.

  Similarly, a downward locking groove 32 is formed at the center of the upper end of the body 22.

  A circular hole 33 through which the wiring 4 passes is formed in the bottom surface portion 29.

  A cover 23 is attached to the body 22 having such a structure. The cover 23 has a side part 34 similar to the body 22, and a lower end opening 35 corresponding to the bottom part 29 of the body 22 is formed below.

  The upper end portion of the cover 23 is formed with an inward (downward) engagement piece 36 in the vertical direction, and the inward engagement piece 37 in the lateral direction is formed at the indoor side end of the side surface portion 34. Is formed.

  Next, the process of attaching the rainproof cover main body 10 to the construction surface 1 to which the waterproof bushing 7 has been attached in advance will be described with reference to FIGS.

  First, before fixing the body 22 to the construction surface 1 to which the waterproof bushing 7 is attached, the waterproof packing 9 is attached to the back surface of the body 22 in a superposed state. The waterproof packing 9 is attached to the body 22 by engaging the peripheral groove 15 on the periphery of the waterproof packing 9 with the protrusion 27 formed on the periphery of the body 22. By engaging the circumferential groove 15 and the protrusion 27, the waterproof packing 9 is integrally polymerized on the back surface of the body 22, and the recesses 16, 24, the insertion port 17 and the insertion port 25, the fixing hole 21, 26 will correspond to each other.

  Next, the body 22 in which the waterproof packing 9 is superposed on the back surface is pressed against the construction surface 1, and fixing screws 38 made of wood screws inserted into the fixing holes 21 and 26 are screwed into the fixing holes 5 of the construction surface 1. Then, the body 22 is fixed to the construction surface 1 (FIG. 8).

  At this time, since the waterproof packing 9 is attached to the back surface of the body 22 in advance, the fixing work of the body 22 is facilitated. Further, when the body 22 is pushed toward the construction surface 1, the feel of the flange 12 of the waterproof bushing 7 can be obtained through the waterproof packing 9, so that the waterproof bushing 7 is securely inserted into the through hole 2. You can check whether it is installed at. That is, when the waterproof bushing 7 is not sufficiently inserted and the collar portion 12 is too far away from the construction surface 1, the state can be confirmed and the collar portion 12 can be pushed in as it is. This is because the waterproof packing 9 is superposed on substantially the entire back surface of the body 22, and the waterproof packing 9 and the flange portion 12 partially overlap in the indoor and outdoor directions.

  Next, after attaching the body 22 and before attaching the cover 23, the outdoor-side wiring 4 is introduced from the circular hole 33 in the bottom surface portion 29, and is connected to the outdoor-side wiring 3 and 4 using the connector 39. . Since the wirings 3 and 4 are connected in the open state before the cover 23 is attached, the operation is easy. Further, since the connector 39 is not fixed to the body 22 or the like and can move freely, it is easy to store the extra length portions of the wires 3 and 4 from the circular holes 33 after the connection.

  Next, after connecting the wires 3 and 4, the cover 23 is attached to the body 22. When attaching the cover 23, first, the locking piece 37 of the side surface portion 34 of the cover 23 is generally aligned with the guide groove 30 of the side surface portion 28 of the body 22. A tapered guide groove 30 is integrated on the outdoor side of the guide groove 30 and has a large vertical dimension S as shown in FIG. Since this vertical dimension S is sufficiently larger than the vertical dimension S2 between the locking pieces 37 of the side surface portion 34 of the cover 23, the operation of aligning both the locking pieces 37 within the range of the vertical dimension S1 of the guide groove 30 is performed. Is easy.

  After the locking piece 37 is generally aligned with the guide groove 30, when the cover 23 is moved horizontally to the indoor side as it is, the locking piece 37 of the side surface portion 34 advances to the indoor side along the guide groove 30, and finally ends. It strikes against the locking groove 31 of the part. Therefore, when the cover 23 is slightly lowered from this state, the locking piece 37 engages with the locking groove 31. The locking piece 36 at the upper end of the cover 23 is also simultaneously engaged in the locking groove 32 at the upper end of the body 22. When the locking pieces 36 and 37 are engaged in the locking grooves 31 and 32, the cover 23 is prevented from coming off in the outdoor direction, and the cover 23 is attached to the body 22. As described above, since the locking piece 37 and the locking groove 31 can be aligned by moving the cover 23 in the horizontal direction, the mounting work of the cover 23 is easy.

  By attaching the cover 23 to the body 22 as described above, the box-type rainproof cover main body 10 is formed. Since the lower end opening 35 of the cover 23 is also closed by the bottom surface portion 29 of the body 22 and the connection portion of the wirings 3 and 4 by the connector 39 can be covered by the rainproof cover body 10, the connector 39 and the like It is possible to prevent deterioration due to exposure to wind and rain or sunlight, and to prevent rainwater or the like from entering the waterproof bushing 7 directly from the outdoor side.

  And even if water intrudes from between the waterproof packing 9 and the construction surface 1 and the water flows down along the construction surface 1, the outer peripheral edge of the flange portion 12 of the waterproof bushing 7 is as shown in FIG. Since it is separated from the construction surface 1 by D, it is possible to prevent water flowing down the surface of the construction surface 1 from entering the waterproof bushing 7.

  Further, the upper end of the flange 12 of the waterproof bushing 7 protrudes upward from the slit 19 of the waterproof packing 9 and comes into contact with the upper surface of the recess 24 of the body 22, so that water flowing down along the surface of the construction surface 1 is slit 19. It is possible to prevent the rainproof cover main body 10 from entering the inside through the.

  Furthermore, since ribs 18 are formed around the entire periphery of the insertion opening 17 of the waterproof packing 9, water flowing down along the back surface of the waterproof packing 9 enters the inside of the rainproof cover body 10 from the insertion opening 17. Can also be prevented. In particular, since the rib 18 is close to the flange 12 of the waterproof bushing 7 (may be abutted), water can be more reliably prevented from entering the inside of the rainproof cover body 10 from the insertion port 17. can do.

  Further, even if the water flowing down the surface of the construction surface 1 reaches the vicinity of the insertion port 17 of the waterproof packing 9, the lower side of the insertion port 17 is blocked in the range E by the flange 12 of the waterproof bushing 7 as shown in FIG. By peeling off, it becomes difficult for water to enter the inside of the rainproof cover main body 10 from the insertion port 17 of the waterproof packing 9.

  Furthermore, since the drainage groove 20 is formed on the lower side of the recess 16, the intruded water can be discharged downward from the drainage groove 20 without accumulating in the recess 16.

  The effects of this embodiment are listed below.

  The rainproof cover 6 of the present embodiment has a waterproof packing 9 having an insertion port 17 having substantially the same shape as the insertion port 25 at a position corresponding to the insertion port 25 of the rainproof cover body 10. 10 is formed so as to cover almost the entire mounting surface, and the insertion port 17 of the waterproof packing 9 is located inside the outer peripheral edge of the flange 12 of the waterproof bushing 7 when viewed along the indoor and outdoor directions.

  Moreover, the rainproof cover 6 of this embodiment is formed with ribs 18 projecting toward the flange 12 side of the waterproof bushing 7 on the entire periphery of the insertion opening 17 of the waterproof packing 9. Therefore, even if the water flowing down along the back surface of the waterproof packing 9 adheres and hangs down above the insertion port 17 of the waterproof packing 9, it becomes difficult for water to enter the insertion port 17 of the waterproof packing 9. .

  Further, in the rainproof cover 6 of the present embodiment, the rib 18 on the peripheral edge of the insertion port 17 of the waterproof packing 9 is in contact with the flange portion 12 of the waterproof bushing 7 at all or part thereof. Therefore, it is possible to more reliably prevent water from entering the insertion port 17. Further, when the rainproof cover main body 10 is attached, if the mounting surface of the rainproof cover main body 10 is pushed, the feel of the flange portion 12 of the waterproof bushing 7 can be obtained through the waterproof packing 9, and the waterproof bushing 7 can be securely connected.
