A conductor connecting structure includes: first and second conductors having terminal portions; a support having recessed portions; first screw members accommodated in the recessed portions; and second screw members that co-fasten the terminal portions of the first and the second conductors by screwing to the first screw members. The recessed portions have first and second wall surfaces that face each other in an opposing direction, and restricting surfaces along the opposing direction to restrict the rotation of the first screw members. The first and second wall surfaces configure a retaining portion to retain the first screw member before being screwed, and an allowable portion located closer to the inlet of the recessed portion. The distance between the first and the second wall surfaces in the allowable portion is greater than the distance in the retaining portion.

A junction box assembly and a terminal assembly configured to prevent a short circuit is provided. In one aspect, the terminal assembly includes a pair of terminals spaced apart from each other and a spacer configured to retain the pair of terminals in a fixed position with respect to each other. In another aspect, the spacer includes a plurality of fuses, and each fuse is electrically connected to a corresponding slot so as to help prevent a power surge through a respective output portion of the terminal. In yet another aspect, the terminal housing has a side wall having a rib extending a height at least as high as the combined height of the output portion and terminal connector when the two are laid on top of each other, preventing the terminal connector from coming into contact with an adjacent terminal connector.

A connection structure, of a short bar forming a conductive path and a land on a printed circuit board, in which the short bar includes a plate portion having a flat plate shape and a protrusion protruding in a stepped shape from a surface of the plate portion, the protrusion is threadably fastened to the printed circuit board by a screw inserted into a land-side through hole formed through the land, from an opposite side of the printed circuit board with respect to the protrusion, in a state where a flat surface portion formed, at a position spaced apart from the surface of the plate portion, on an outer surface of the protrusion is in close contact with the land.
