Abstract
A wiring unit 1 with a plurality of printed circuit boards 2 which are successively stacked and pin units 3. The printed circuit boards 2 each has a conductor pattern 7 formed on the surface 6a of an insulating plate 6. The conductor pattern 7 is composed of a first plurality of belt-like conductors 11 and a second plurality of belt-like conductors 12. Through-holes 13 are formed at points 14 where the belt-like conductors 11 and 12 cross each other. The pin units 21 each is composed of a conductive pin 20 and a C-bush 21. The C-bush 21 is provided with a pair of spring segment segments 24. The C-bush 21 is press-fit into the through-hole 13 to sandwich the printed circuit board 2 between the pair of spring segments 24. The C-bush 21 is communicated with the conductor pattern 7. The pin 20 is inserted into the through-hole 13 into which the C-bush 21 is press-fit. The conductive pin 20 is communicated with the C-bush 21. In this configuration, the wiring unit can be minimized in production cost and size.
