SEALING STRUCTURE OF POWER DISTRIBUTION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a sealing structure of a power distribution apparatus capable of reducing labor and time needed for fastening work of a sealing screw, and reducing the using number of expensive sealing screws.SOLUTION: A cover 11 is put on a base 12 and slid to the side of a wire insertion port 12b of the base 12, and thus an edge 11a of the cover 11 is fitted to an edge 12a of the base 12. A sealing structure of a watt-hour meter has a fitting maintaining structure in which a sealing cap 14 or 15 put on the head of a sealing screw 13 screwed to the base 12 interferes with a sidewall 11b1 or 11b2 provided on the cover 11 in the state of being fitted to the base 12, blocks the slide of the cover 11, maintains the state that the cover 11 is fitted to the base 12, and performs sealing.
