<p>PROBLEM TO BE SOLVED: To easily detect in a short time whether or not a fuse of an electric connection box is blown out. SOLUTION: In an upper cover 3 of an electric connection box storing a fuse block 4 with a plurality of mounted fuse members, a checker portion 9 is provided for detecting whether or not each fuse member is blown out in contact with both terminals of the fuse member. Also providing in the checker portion 9 contact terminals for making contact them with both terminals of each fuse member, the checker portion 9 is slid by the operation from the outer surface of the upper cover 3 to switch on or off the contactings of the contact terminals with the terminal portions of each fusing member. Furthermore, whether or not the fuse members are blown out is detected by checking whether such light-emitting elements as LEDs are on or not.</p> |
