1. Description

Electronic kit for experimental construction of circuits and circuits for teaching and learning purposes

1.1. Purpose of the invention

With this kit, a large number of circuits can be built very easily and - these are presented in such a way that, with the help of appropriate explanations, they enable any "layman" to understand the way the individual components work experimentally ₍ -> to 3rfai1rfc.ii and "u.

At the same time, we intend to develop the ^dukascen in such a way that it can be manufactured cost-effectively in large quantities using rational manufacturing processes.

1.2. State of the art

Electronic learning kits are used both in school and outside of school. The components are plugged or clamped onto the circuit board using plug-in or clamping devices. I have developed a kit myself in which the components are firmly connected to magnetic plates and are then attached to a metal plate and connected to the conductor tracks (see user manual no. G 8900186.9).

1.3. Criticism of the state of the art

The learning and experiment kits available on the market require a very high cost for the plug-in board and the plug-in parts. In addition, this costly design of the kits hinders and in some cases makes it impossible to understand how the individual components work and to gain an overview of the mutual effects of the components on one another.

In the kit I developed in 1989 (see G 8900186.9) the components are attached to square magnetic plates by soldering so you need "each component

f a magnetic plate. If this kit is produced in series

The magnetic plates must be used to solder the

V den. In addition, the three different slide work

■;. flat conductor tracks are applied.

ti 1.4. Solution

'_ In the kit shown here, the electronic components are soldered onto small circuit board disks. Therefore, for the electrical connection of the components, only 15 bar magnet disks are required, which are firmly inserted into the holes in the plastic plate. The number of electronic components can therefore be increased as required without having to reduce the number of bar magnets. In addition, the magnets no longer have to be coated with copper.

The three different work plans, in which conductor tracks are applied to foil or paper, are now replaced by an etched circuit board, without losing the clear and immediately recognizable structure of a circuit. With the help of the magnets and the perforated circuit board disks, a safe and functional ?;e/i contact connection is guaranteed.

Fig. 9 shows a reduction of the layout (t'oa, 'i) for·
the production of the copper board. The copper coating
is etched away in such a way that the covered conductor tracks remain intact.

The board is now drilled in 15 places according to figure 9 with a drill diameter that is exactly ? mm smaller than the diameter of the magnet. Then
Plastic plate (Fig. 9, Pos.1) of the same size as in Figure 9 also 15 holes with a drill bit
drilled according to the magnets.

Both plates are now glued together as shown in Figure 9, items 1 and 2. Finally, the magnets are glued into the holes from below (Fig. 9, item 4). Now the components that are to be soldered onto the perforated board disks can be
are placed over the magnet so that the holes fit into the holes in the plate, but are still 1/1C to 2/1C mm away from the magnet (F ¹ Is. 9, Tos. 5).

1.6. Research

The result of my research is that there is a utility model protection (Ur. G 7617554.7) from June 10, 1977, but these are electrical and not electronic components that are not attached with magnetic force but with holding devices. The kit I developed in 1989 (G 8<y CC186.9) is also used for experimental construction of circuits and switches. However, with this new concept, a completely different kit was developed that must be protected by a separate utility model.
