Abstract

In an electrical junction box with a fuse, a safety plug including a plug body which is moved vertically to electrically connect two terminals to each other and disconnect them from each other, at least one pair of electric wires, and a fuse are fixedly mounted in a frame, the electric wire is connected directly or indirectly to one of the terminal, the terminal is connected directly or indirectly to one end of the fuse, the other end of the fuse is connected directly or indirectly to the electric wire, the plug body is protruded outside from the frame, and a sealing member sealingly closes the gap between the plug body and the frame.

Claims

1. An electrical junction box comprising:

a safety plug including;

a plug body which is moved vertically to electrically connect two terminals to each other and disconnect said two terminals from each other, said plug body being protruded outside from a frame of said electrical junction box, wherein said frame has a tubular portion for substantially receiving said slug body,

at least one pair of electric wires connected to said terminals, respectively;

a fuse fixedly mounted in said frame; and

a sealing member sealingly closing the gap between said plug body and said frame, wherein said sealing member fits in a groove formed on said plug body,

wherein one of said pair of electric wires is connected to one of said terminals in one of directly or indirectly, the other terminal is connected to one end of said fuse in one of directly and indirectly and the other end of said fuse is connected to the other electric wire in one of directly and indirectly.

2. An electrical junction box as claimed in claim 1, wherein a circuit formed by arranging the one electric wire said two terminals, said fuse, and the other electric wire in the stated order is substantially U-shaped.

3. An electrical junction box comprising:

an electrical junction box body which is hollow and elongated, and which has first and second housings respectively at both ends thereof as viewed in the direction of longitudinal axis thereof, and an opening section formed on one side wall thereof in such a manner that said the axis of said opening section is perpendicular to the direction of longitudinal axis;

a cover engaged with said opening section, said cover being movable in a direction perpendicular to the direction of longitudinal direction of said electrical junction box body;

a fuse which held in said cover, said fuse having connecting pieces extended from both ends thereof, said fuse being moved together with said cover;

a first terminal secured to said first housing, said first terminal having the rear end which is connected to a first electric wire, and the front end which is engaged with said connecting piece extended from one of said both ends of said fuse;

a second terminal secured to said second housing, said second terminal having the rear end which is connected to a second electric wire, and the front end which is engaged with said connecting piece extended from the other end of said fuse; and

a sealing member which sealingly closes the gap between the outer wall of said cover and the inner surface of said electrical junction box cover.

4. An electrical junction box as claimed in claim 3, wherein said first terminal and said second terminal have a pair of elastic pieces, respectively.

5. An electrical junction box as claimed in claim 3, wherein said first terminal and said second terminal have multi-springs on inner surfaces of said first terminal and said second terminal respectively.

6. An electrical junction box as claimed in claim 3, further comprising a second sealing member which sealingly closes the gap between the outer wall of said cover and the inner surface of said electrical junction box cover where said first sealing member is positioned in a first groove formed along a lower outer edge of said cover so that said cover may be temporarily locked and said second sealing member is positioned in a second groove formed above said first groove.

7. An electrical junction box as claimed in claim 3, further comprising a handle on a top portion of said cover.
