Researchers Submit Patent Application, "Mechanical Spacer with Non-Spring Electrical Connections for a Multiple Printed Circuit Board Assembly", for Approval

By a News Reporter-Staff News Editor at Electronics Newsweekly -- From Washington, D.C., VerticalNews journalists report that a patent application by the inventors Manushi, Ligor (Northville, MI); Janson, John (Plymouth, MI); Gerber, Keith (West Bloomfield, MI); Avalos, Hiram (Ann Arbor, MI), filed on November 27, 2013, was made available online on June 5, 2014.

The patent's assignee is Robert Bosch GmbH.

News editors obtained the following quote from the background information supplied by the inventors: "The present invention relates to a mechanical spacer with built in, non-spring electrical contacts to be placed in a multiple printed circuit board (PCB) assembly to create an electrical connection between circuit paths of upper and lower circuit boards. Alternatively, one or both of the upper and lower circuit boards could be replaced with another circuit-based construction (e.g., LTCC, MID, etc.).

"A conventional PCB includes a plurality of electronic components, and is generally formed with a plurality of circuit paths for establishing electrical connection among the electronic components. The maximum number of circuit paths is proportional to the overall surface area of the printed circuit board. Printed circuit boards are often designed in multi-layered forms, thereby increasing the total surface area for forming circuit paths and for assembling the electronic components thereon.

"A plurality of spacer contact posts are conventionally sandwiched between the upper and lower circuit boards to create connection of the circuit paths of the circuit boards with each other and to facilitate heat-dissipation."

As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventors' summary information for this patent application: "In one embodiment, a spacer and electrical connector assembly for printed circuit boards is provided. The assembly includes a first member configured to be placed between two of the printed circuit boards to provide a required spacing between the printed circuit boards; at least one second member disposed adjacent to the first member, the second member extending along a length of the first member and at least partially bracketing an upper surface and a lower surface of the first member, thereby providing an electrical connection between the printed circuit boards. The assembly also includes a plurality of contact portions disposed on at least one of the upper and lower surfaces.


"FIG. 1A is a cross-sectional view of a spacer assembly according to an embodiment of the invention.

"FIG. 1B is an exploded view of FIG. 1A.

"FIG. 2A is a perspective view of the spacer assembly of FIG. 1.

"FIG. 2B is a perspective view of an alternative spacer assembly

"FIG. 3 is a plan view of an alternative embodiment of a spacer assembly.

"FIG. 4 is a plan view of spacers distributed on a printed circuit board.

"Before any embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways."
