<p>PURPOSE:To easily execute the loading/unloading of CPU board and to efficiently change a wiring board by providing sockets in an outside direction the peripheral edge of a bus printed wiring board and inserting connecting pins at the side of the CPU board into the sockets. CONSTITUTION:Lead pins 5 at one end of the sockets 4 are bent at a right angle in the midst and the bent parts 5a are inserted into pin holes 3 and soldered. Then, the sockets 4 are fixed in the outside direction on the peripheral edge of the bus printed wiring board 1 and they are simultaneously connected to single lines 2. The three sockets 4 are integrally connected in a group. The plural printed wiring boards 1 are vertically arranged along the same axial line at certain intervals and the plural CPU boards 7 are radiatedly arranged on the outer peripheries of the wiring boards 1 in an orthogonal direction with the substrate angle of the wiring substrate 1. The connecting pins 9 of board connectors 8 in the reed part of the inner peripheral side end part of the boards 7 are inserted into the inserting holes 6 of the sockets 4. Thus, the signal lines 2 of a pair of the sockets 4 are connected to the same board 7.</p> |
