Abstract: A bolt-fastened terminal connects to a wire that includes an aluminum core wire of an aluminum-based metal. The terminal includes a wire connection configured by a copper-based metal material and continuous with an electric contact that includes a bolt hole, the wire connection being welded and electrically connected to the aluminum core wire. A surface of the wire connection is coated with a first metal such as nickel and a surface of the electric contact is coated with a second metal such as tin. The first metal and the second metal, which are configured by different metals, are selected from metals between hydrogen and aluminum, aluminum having a negative electric potential with reference to the electric potential of hydrogen and a high ionization tendency, and the second metal is a metal having a smaller negative electric potential and lower ionization tendency than the first metal.

Abstract: A protector that accommodates convoluted conduits having different diameters includes a main body and a lid that covers an upper surface opening of the main body. A convoluted conduit engagement portion having ribs that fit troughs of a large-diameter convoluted conduit extends from a bottom wall on one end side in the length direction of the main body to internal surfaces of two side walls. A large-diameter convoluted conduit engagement portion having ribs that fit the troughs of the large-diameter convoluted conduit is provided on an internal surface on one end side in the length direction of the lid, and a small-diameter convoluted conduit engagement portion having ribs that fit troughs of a small-diameter convoluted conduit is provided on an internal surface of the other end side. The lid is rotated by 180 degrees to correspond to an outer diameter of a convoluted conduit and connected to the main body.
