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 wiring module to be attached to a plurality of power elements which store or generate power includes a bus bar connecting the power elements to each other or connecting the power element and a load to each other, an abnormality detection element detecting an abnormality of the power element, and an insulating protector holding the bus bar and the abnormality detection element. The insulating protector is integrally provided with a first holding shaft portion and a second holding shaft portion which position and hold the bus bar by fitting the bus bar there onto, and an element holding portion which position and hold the abnormality detection element by fitting the abnormality detection element there into.

A fuse line fixing structure of a fuse includes a base having first and second support sections. The first support section has two sides each forming a first wing and a first concave surface is formed between the first support section and the first wings. First and second electrodes are respectively arranged at two ends of the base. The first electrode includes a first curved plate arranged between the first support section and the first wings. The first curved plate has a convex engagement surface positioned against the first concave surface and a concave engagement surface facing toward an upper side of the first concave surface. The fuse line straddles between the first and second support sections and has an outer circumferential surface in mutual contact, through surface to surface engagement, with the concave engagement surface of the first curved plate.
