<P>PROBLEM TO BE SOLVED: To provide the airtight construction of a distribution panel where airtightness is high due to large contact area and large airtightness between a cable and an air-tight material and the heat radiatability of a distribution panel body improves because it need not increase the amount of projection from the wall face of the distribution panel and there is no influence on airtightness even when the distribution panel body is deformed due to its installation environment. <P>SOLUTION: A flange 6b is made at one edge of a roughly cylindrical frame 6a, and the frame 6 is made in parts so that engagement and break may be possible by engaging parts 6d and 6f, and airtight materials 5 consisting of soft materials are provided inside each of these divided frames 6. A wiring hole 3 to be made at the wall face 2 to which the distribution panel is to be attached is made larger than the frame 6a and to be smaller than the flange 6b, and the fellow frames 6 are fitted together to catch a plurality of cables 4 threaded into the wiring hole 3 with the airtight materials 5, and the engaging parts 6d and 6f are locked to fix the frame 6, and the frame 6a is plugged into the wiring hole 3 until the flange 6b of the frame 6 abuts on the wall face 2. <P>COPYRIGHT: (C)2008,JPO&INPIT |
