Structure of an electronic device including a number of printed circuit boards
First Claim
1. A structure of an electronic device, comprising:
- at least one mother board elongated in an up-and-down direction and provided with a wiring circuit network comprising printed wirings on a first surface thereof;
a plurality of first printed circuit boards mounted on said at least one mother board at a first position in the up-and-down direction of said at least one mother board and having a plurality of surfaces positioned parallel to the up-and-down direction and substantially perpendicular to the first surface of said at least one mother board, said plurality of first printed circuit boards each carrying a number of electronic parts therewith and comprising a printed circuit electrically connecting said electronic parts, and connection terminals formed by ends of said printed circuit;
a plurality of second printed circuit boards mounted on said at least one mother board at a second position in the up-and-down direction of said at least one mother board and having a plurality of surfaces positioned perpendicular to the up-and-down direction and substantially perpendicular to the first surface of said at least one mother board, said plurality of second printed circuit boards each carrying a number of electronic parts therewith and comprising a printed circuit for electrically connecting said electronic parts, and connecting terminals formed by ends of said printed circuit; and
connector means for connecting said connecting terminals of said first printed circuit boards to said connecting terminals of said second printed circuit boards via said wiring circuit network provided on said at least one mother board, said connector means being connected to said first and second printed circuit boards to connect said first and second printed circuit boards to said at least one mother board, said connector means including unit wirings, said units wirings being positioned so as not to intersect one another;
said wiring circuit network comprising a single layer printed circuit.

Abstract
An electronic device has a rack accommodating a mother board and a first and a second printed circuit board (PCB) group mounted on the mother board. The PCBs belonging to one of the first and second groups are mounted on the mother board in an upper half of the rack while having the surfaces thereof positioned substantially parallel to the side walls of the rack. The PCBs belonging to the other group are mounted on the mother board in a lower half of the rack while having the surfaces thereof held substantially horizontal. If necessary, a third group of PCBs are positioned above one of the first and second PCB groups and mounted on the mother board with their surfaces held substantially horizontal. The wiring network between the first and second (and third) PCB groups is formed on the surface of the mother board by printing. Two electric fans may be respectively located between the first and second PCB groups and between the third and first (or second) PCB groups.
