Electrical junction box with stacked insulating plates and bus-bars with stepped tabs

摘要

An electrical junction box is constituted by accommodating bus-bar circuit board composed of a plurality of bus-bars and an insulating plate in a case member composed of upper, lower and side cases. The bus-bar has a terminal for a connector vertically erecting from the surface of the bus-bar and introduced into fastening portions of the upper and lower cases and a terminal extending in parallel to the surface of the bus-bar while keeping a level difference so as to be accommodated in the housing of the side case at a predetermined pitch. In order to easily align the terminals and easily assemble and fasten a predetermined terminal or a connector, a boss and a cut portion are formed to correspond to the insulating plate for the purpose of supporting the terminal. As an alternative to this, a support member is inserted between the insulating plates.
