A light sensor (CdS), a light emitting diode (led), a variable resistor (vr), a microchip (ic), a connecting line (w), etc. by plugging in the electrical connection to configure and disassemble the circuit.

Reference numeral 2 in the drawings is a power supply.

In addition, as shown in FIGS. 3 and 4, the educational electronic circuit board 21 includes a power switch 24, a plurality of

sockets

22 and 23, and protrusions 25 having a predetermined size. In the protrusion 25,

blocks

In addition, as shown in FIGS. 5 and 6, another educational electronic circuit board 31 includes an element such as a resistor r as a base 36a, a cover 36b, an attachment plate 36c, and a metal terminal 36d. And a component block (36) consisting of 36d, and the component block (36) is a condenser terminal (33), a speaker terminal (32), a switch terminal (34), and a power connection terminal made of the electronic circuit board (31). In accordance with 35, the

metal terminals

36d and 36d 'can be attached to form a circuit.

In addition, the educational electronic circuit board 47 makes an electronic device board 41 on which various electronic devices are mounted, as shown in FIGS. 7 and 8. The electronic device plate 41 is made of an insulating material (b) and the magnet case (p1, p2) for pressing the cylindrical magnet (Mc1, Mc2) at both ends, the two cylindrical magnets (Mc1, Mcc) are The leads l1 and l2 of a device such as a light emitting diode are connected between the connecting lines w1 and w2 and between the connecting lines w1 and w2.

The

electronic device plates

41, 42, 43, 44, 45, and 46 as described above constitute a circuit by connecting the cylindrical magnets Mc1 and Mc2 with each other, such as the power applying plate 46, to allow electrical communication. . In the drawings, reference numeral ps denotes a power supply and sw denotes a switch.

However, the educational electronic circuit board configured as described above has the following problems.

1 and 2, the braid board 1, which is an educational electronic circuit board as shown in FIG. 1, is connected to the socket by electrically inserting a lead of an electronic component, such as a resistor r and a light emitting diode, to be electrically connected. It was difficult to observe with the naked eye. In addition, it is difficult for educated children to understand the electrical flow of circuits because of the cluttered insertion of electronic components, and because it is so different from PCB, it is difficult to educate them to see and understand electronic circuit boards in electronic products. have.

In addition, the educational electronic circuit board 21 as shown in FIGS. 3 and 4 may be assembled by first fitting various electronic devices to the

blocks

26, 27, 28 of various shapes, and then inserting them into the protrusions 25. Electrical connection, but the

In addition, since the electronic circuit board 21 must be several in order to make an electronic circuit that is complicated and requires a lot of parts, it is too different from the PCB as in the braid board 1 with the costly problem. It is difficult to educate students to understand electronic circuit boards in electronic products.

In addition, since the educational electronic circuit board 31 shown in FIGS. 5 and 6 can be assembled without soldering a predetermined circuit, the educational electronic circuit board 31 is made of a single unit that cannot be variously applied.

In addition, since the parts are made into blocks 36, there is a problem that it is too different from the electronic circuit board in the actual electronic product, which makes it difficult to educate the electronic circuit. In addition, since the electronic device must be blocked, there is a problem in that the manufacturing cost increases and the price of the product increases.

In addition, the electronic circuit board 47 for education as shown in FIGS. 7 and 8 is blocked by connecting a device such as a resistor r and a light emitting diode led and cylindrical magnets Mc1 and Mc2. The circuit is electrically connected by making a 41 to connect or laminate the cylindrical magnets Mc1 and Mc2. This results in a bulky shape that is too different from the electronic circuitry.

The base plate 110 is a transparent synthetic resin material in the present embodiment, a rectangular plate shape. However, the base plate 110 may be made of an insulating material and may be any plate shape. Of course, if the base plate 110 is transparent, it may be easy to check the configuration provided on the front and rear surfaces of the base plate 110 when using both the front and back surfaces.

The base plate 110 is formed with a fastening hole 112 in which the land 120 to be described below is installed. The fastening hole 112 is formed through the base plate 110. A fastening tab 114 is formed on an inner surface of the fastening hole 112. The fastening hole 112 is good to have a predetermined interval between the adjacent ones.
