Electric connection box having an improved insulating structure
View Patent ↗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.
1. An electric connection box comprising:
a cover for receiving wiring boards therein;
first wiring board having at least one first insulating rib formed thereon; and
a second wiring board having at least one through hole portion formed at region for insulation;
wherein said first wiring board and said second wiring board are stacked together, and are received within said cover, and said first insulating rib of said first wiring board projects through said hole portion of said second wiring board to insulate a circuit of said second wiring board, wherein:
at least one second rib is formed on said second wiring board;
said first wiring board has at least one through hole portion formed at region for insulation; and
said second insulating rib projects through said hole portion of said first wiring board to insulate a circuit of said first wiring board.
2. An electric connection box according to claim 1 , wherein said first insulating rib is molded integrally on said first wiring board, and said second insulating rib is molded integrally on said second wiring board.
