This will be explained based on the diagram. Reference numeral 1 denotes a container body, which integrally forms a bulging portion 4 having an opening window 3 that is sequentially inclined toward the plate portion 2 and improves the drainage effect. 5 is a screw hole;
This is for fixing to the construction material X or an embedded box (not shown) embedded in the construction material X. Sawtooth grooves 6 are formed in a substantially U-shape in succession on the periphery of the opening window 3, and through holes 7 are formed in the plate portion 2 corresponding to the grooves 6. The container body 1 is molded from thermoplastic resin to prevent damage due to external impacts. Further, a plurality of through holes 7 may be formed if necessary. The second mold is used to mold the vessel body 1.
As shown in Figures a and 2b, it consists of a stationary mold D having sliding pins A and blocks B, a movable mold E, and a slide core F. 8a,
Reference numeral 8b denotes a cavity in which the locking portions 9a and 9b are molded, and is formed to communicate with the sawtooth groove 6 and the through hole 7, respectively, as shown in FIGS. 3a and 3b. Reference numeral 10 denotes a U-shaped protruding wall, and as shown in FIGS. 3a and 3b, cavities 8a and 8b are formed by shifting the mold part C, and a slide core F is provided in the cavity of the protruding wall 10. After replacing the slide core G with a translucent thermoplastic resin, the tongue piece 9d, locking part 9a,
Projecting wall 1 locked in groove 6 or through hole 7 by 9b
0 is molded around the periphery of the opening window 3 in a substantially U-shape. As shown in FIG. 4, the locking portion 9b has a stepped portion 9c.
It may be made more difficult to separate by forming a . Reference numeral 11 denotes a connecting device, which includes a container 16 made of thermosetting resin that combines a body 12, a cover 13, and a surface plate 15 having a surface portion 14 that fits into the opening window 3, and a blade housed in the container 16. It consists of a receiving spring 17, and a plug blade insertion hole 18 is formed in the surface portion 14. 19 is a lock spring for connecting electric wires. Incidentally, the electric wires may be connected using screws. 20 is a door, and a constant spring 2
The force of 1 closes the plug blade insertion hole 18 to prevent dust from entering. 22 is a protrusion, and a spring 2
1 and positions the spring 21. In this embodiment, the blade receiving spring 17 is of a hook type to prevent the plug from coming off. Then, the surface portion 14 is fitted into the opening window 3, and the hole 24
The connecting device 11 is housed and fixed in the bulge 4 by screwing a screw 27 passed therethrough into a hole 26 formed in the cylinder 25.
