Abstract

The present invention relates to a waterproof electric plug with fuses that comprises a housing, a fuse holder, a fuse cover, two plug blades, two tubular fuses, and power lines. When the cover and the holder are inserted into the housing, the complicated structure that is formed will prevent any water or liquid from entering into the housing and the holder. The cover can be pushed to expose an opening in the housing through which the tubular fuses can be replaced.

Claims

1. A waterproof electric plug with fuses, comprising:

a housing having a substantially rectangular contour and a hollow interior, said housing having openings formed in opposing front and rear ends thereof in open communication with said hollow interior, said rear end having a pair of semi-circular grooves formed therein, said housing having an upper wall with an opening formed therethrough, and a pair of horizontal flanges formed on opposing sides of said upper wall opening and extending from a lower surface of the upper wall, said pair of flanges defining a pair of grooves disposed on opposing sides of said upper wall opening;

a fuse holder inserted into said hollow interior of said housing, said fuse holder having a pair of outer side walls and a middle wall disposed between said outer side walls for dividing said fuse holder into a pair of spaces for respectively receiving tubularly shaped fuses therein, each of said pair of spaces having a stopping block formed therein for trapping a respective power line in said space, said fuse holder having a front wall with a pair of slotted openings and a pair slot mortises formed therethrough, said fuse holder having a rear wall with a pair of semi-circular grooves formed therein for combination with said semi-circular grooves of said rear end of said housing for defining a pair of holes to tightly hold respective power lines;

a pair of plug blades disposed in said fuse holder and having a front end extending through said pair of slotted openings, each tubularly shaped fuse being connected between a rear end of a respective one of said pair of plug blades and a respective power line terminal;

a rectangular cover having (a) a push plate formed adjacent an end portion of said cover and extending from an upper surface thereof, (b) a pair of sliding strips respectively formed on opposing sides thereof for slidable engagement with said pair of grooves disposed on opposing sides of said upper wall opening, (c) a pair of strips projecting downwardly from a lower surface of said cover for insert into said pair slot mortises, and (d) a recess formed between said projecting strips for receiving an upper portion of said middle wall therein.
