Claims

[Scope of utility model registration request]

A plurality of bodies made of a conductive material, each having a male screw having a diameter smaller than that of the body at one end of the body, a female screw formed at the other end of the body, and the length of the body being approximately equal to the distance between the printed circuit boards. The fitting has a coupling hole through which the male thread of the fitting passes, and a conductive common signal part is printed on at least one of the front and back sides of that part, and the common signal part is printed on the end face of the female thread side of the fitting. A plurality of printed circuit boards are sandwiched between the step part on the male thread side, and a female thread is formed at the lowest part to fit with the male thread of the fixture, and the part is configured to have conductivity. A multi-stage printed circuit board device characterized by comprising a chassis.
