ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention is directed to the assembly of electrical components and more particularly to a mounting system to support electrical components in a stacked relationship to one another using a mounting frame.
2. Description of the Prior Art
At present when it is desired to mount a number of printed circuit boards in a stacked relationship to one another, it is necessary to use insulated stand-offs coupled between and to each of the printed circuit boards. The board's stand-offs must be positioned so as not to interfere with the circuits of the printed circuit boards or components on the printed circuit boards. The two printed circuit boards must be coordinated so that the stand-offs or other mounting hardware is properly positioned thereby limiting the interchangeability of the printed circuit boards. The use of stand-offs or other mounting hardware generally increases the size of the printed circuit boards. Also, such stacking approaches are generally limited to two printed circuit boards.
SUMMARY OF THE INVENTION
The invention is directed to a mounting system to support a plurality of electrical components in stacked relationship to one another. The mounting system makes use of a frame which establishes three parallel planes, a top plane, a bottom plane and an intermediate plane there between. The planes are delineated by a series of ridges and spaces at each of the three plane levels. Locking devices at each plane level holds a printed circuit board (PCB) in position at each plane. The frame and locking devices are integral and made of insulating material. Interconnection between the PCBs can be made by the use of straight pin headers or flexible, flat, ribbon cable. Various combinations of PCBs can be used with the same frame. Fewer than all three planes can also be used as necessary. It is an object of this invention to provide a novel mounting system.
It is an object of this invention to provide a novel mounting system to support a plurality of electrical components in stacked relationship to one another.
It is another object of this invention to provide a novel mounting frame on which and to which a plurality of PCBs can be mounted.
It is still another object of this invention to provide a novel mounting frame which includes locking devices at each plane to retain PCBs at the proper frame plane.
It is yet another object of this invention to provide a novel mounting system which does not require the use of stand-offs or other mounting hardware between the PCBs in the stack.
Other objects and features of the invention will be pointed out in the following description and claims and illustrated in the accompanying drawings, which disclose, by way of example, the principles of the invention, and the best mode which is presently contemplated for carrying them out.
