Kit of building blocks for constructing educational electronic circuits

摘要

Kit of building blocks for constructing educational electronic circuits comprising a ferromagnetic base plate (10) with the diagram (21) of the circuit to construct. A transparent plastic sheet (30) covers the diagram. A group of magnets (40, 41) rest on the plastic sheet attracted by the plate (10). The surface of the magnets (40, 41) is electrically conducting. A plurality of building blocks can be detachably mounted on the magnets (40, 41), each magnet (41) connecting the steel sheets (702) of the building blocks that rest on it. The steel sheets of the blocks are designed so that the attraction forces that arise between the magnets and the sheets drive the modules exactly to a desired equilibrium position.

1. Building block for constructing educational electronic circuits comprising:
a) a base printed circuit board (PCB) (710, 720, 730, 810, 850, 911, 921, 931, 951) with copper pads (713, 726, 912), plated through-holes (7053) or ferromagnetic steel sheets (902) in which it is possible to solder an electronic component (701, 703, 705), b) ferromagnetic steel sheets (702, 801, 902, 952) soldered to the PCB to fix the building block by magnetic attraction to magnets (41) whose surface is electrically conducting, wherein said steel sheets are contact plates for the building block that connect the electrically conducting surface of the magnets (41) with points of the PCB (712, 722, 7054, 814, 912) and wherein copper tracks of the PCB connect said points with the copper pads (713, 726, 912), plated through-holes (7053) or ferromagnetic steel sheets (902) in with it is possible to solder an electronic component (701, 703, 705), wherein c) each ferromagnetic steel sheet (702, 801, 902, 952) has a shape formed by several sides, wherein a first side (7022) of said shape is the result of rotating 90° a second side (7021) of said shape around a rotation center (7023) that is a vertex of the steel sheet or an external point to the steel sheet, d) the ferromagnetic steel sheets (702, 801, 902, 952) have a shape, such that when a face of a steel sheet of a building block rests by its center of rotation (7023) on a base of one of said magnets (41) wherein said magnet (41) is a right prism and wherein the bases of said prism are a circle or a regular polygon with a number of sides multiple of four, a magnetic attraction between the magnet and the steel sheet arises that takes the steel sheet to a position with respect to said magnet that is an equilibrium position in which the magnetic attraction disappears or is neutralized by a retaining stop (813, 903) that protrudes from the face of the steel sheet (801, 802, 902, 952) that contacts the permanent magnet (41), and in said equilibrium position said center of rotation (7023) of said steel sheet coincides with the geometric center of said circle or with the geometric center of said regular polygon of the base of said magnet (41).
