Abstract

A circuit board assembly which is flexibly set up in horizontal, vertical, horizontal/vertical, and N-dimensional directions according to requirements, by means of the connection of basic solderless circuit boards, which comprises each four raised dovetail strips on its four vertical sides, via one or more double-sided connecting members, which comprise each two opposite dovetail grooves, one or more four-sided connecting members, which comprise each four dovetail grooves on its four sides, and/or one or more dovetail grooved clampings, which comprise each at least a dovetail groove and at least a corrugated hole.

Claims

1. A circuit board assembly comprising, a basic solderless circuit board of generally rectangular configuration including opposite faces and four elongated sides extending between said faces, each of said sides on the basic solderless circuit board having a length and a width and having an elongated projection extending outwardly thereof and extending along the length of the associated side, each projection having a generally dovetail cross-sectional configuration, a connector means for connecting said basic solderless circuit board with further means, said connector means having a plurality of sides, one of said sides of the connector means having an elongated groove formed therein of generally dovetail cross-sectional configuration complementary to the configuration of said elongated projections and receiving one of said elongated projections, another of said sides of the connector means having a further groove formed therein, and further means supported in said further groove for supporting said basic solderless circuit board and said further means in a predetermined position relative to one another.

2. An assembly as defined in claim 1 wherein said another side of said connector means is disposed substantially parallel with said one side thereof, said further groove having a configuration similar to said elongated groove.

3. An assembly as defined in claim 1 wherein said connector means includes four sides extending substantially at right angles to one another, all of the grooves in the connector means being of similar configuration.

4. An assembly as defined in claim 1 wherein said further groove is a corrugated groove.

5. An assembly as defined in claim 4 wherein said connector means includes another corrugated groove in said another side of the connector means, said corrugated grooves being spaced from one another.

6. An assembly as defined in claim 5 including an opening formed in said another side of the connector means between said grooves so that said corrugated grooves comprise resilient clamping means.

7. An assembly as defined in claim 4 wherein said connector means includes a third side and a fourth side, dowel means projecting from said third side, and dowel holes being formed in said fourth side for receiving dowel means on an adjacent connector means.

8. An assembly as defined in claim 4 wherein said further means comprises a printed circuit board.

9. An assembly as defined in claim 4 wherein said further means comprises a component card for supporting electronic components.

10. An assembly as defined in claim 4 wherein said further means comprises an explanatory card including indicia thereon to assist in logic training or experimentation.

11. An assembly as defined in claim 4 wherein said further means comprises sheets of reference paper.

12. An assembly as defined in claim 1 wherein said further means comprises a component card, said component card including four sides, each of said sides on the component card having an elongated projection extending outwardly thereof, the projection on each of said sides of the component card having a generally dovetail cross-sectional configuration.

13. An assembly as defined in claim 1 including an explanatory card fastened to said basic solderless circuit board, said explanatory card including indicia thereon to assist in logic training or extermination.

14. An assembly as defined in claim 1 wherein said basic solderless circuit board has supported thereon a printed circuit board to serve as a functional board.

15. An assembly as defined in claim 9 wherein said further means comprises another basic solderless circuit board.

16. An assembly as defined in claim 1 wherein said basic solderless circuit board includes a plurality of terminals, at least one of said terminals comprises a unitary plug pin for plugging into a printed circuit board.
