Abstract: A window is formed in a common use cover for receiving one or a plurality of wiring boards therein, the inside and outside of the cover communicating with each other through the window. A convex portion for enabling the kind of the wiring board to be distinguished is formed on each of the wiring boards, and when the wiring boards are properly received within the cover, the convex portions project through the window to the exterior of the cover, or are disposed in facing relation to the window, and when the wire boards are improperly received in the cover, the convex portions are interfered with a wall of the cover. Each of the convex portions has an obverse/reverse distinguishing-function portion for enabling the obverse and reverse of the wiring board to be distinguished.

Abstract: An electric connection box includes a first cover and a second cover each having connector mounting portions, a first wiring board and a second wiring board which are mounted in a stacked manner between the first and second covers, a plurality of press-contacting terminals which are disposed in the connector mounting portions of the first and second covers, and are inserted in the first and second wiring boards, and a connecting wire which is selectively connected to the press-contacting terminals, and is arranged to extend over the first and second wiring boards when the first and second wiring boards are stacked together.

Abstract: An electric connection box includes a first wiring board having first insulating ribs formed thereon, and a second wiring board having through hole portions (for respectively passing the first insulating ribs therethrough) formed respectively at regions of insulating of circuits from each other. The first wiring board and the second wiring board are stacked together, and are received within covers. The first insulating ribs of the first wiring board project respectively through the hole portions of the second wiring board to insulate the circuits of the second wiring board from each other.
