<p>A mechanical connection of printed circuit boards is disclosed for building three-dimensional structures from flat printed circuit board waste. The printed circuit boards are interconnected at right angles to each other and a slot (2) with a curved or polygonal progression is cut into a printed circuit board. A tongue set in a single piece through a more narrow strip (4) on the edge of another printed circuit board may be inserted into the slot (2). When the tongue is inserted into the slot (2), the marginal areas (6) of the tongue that project sideways beyond strip (4) snap behind the outer curved edge (8) of the slot (2).</p> |
