Description

  The present invention relates to a circuit creation kit for creating an electric circuit / electronic circuit.

  Conventionally, breadboards are used for learning and practical training of electric circuits and electronic circuits. As is well known, a breadboard has a plurality of metal holes arranged therein, and a circuit is formed by inserting terminals of circuit elements into the metal holes. However, the circuit created by the breadboard is a wiring whose appearance is far from the circuit diagram. For example, when the circuit diagram of FIG. 9A is actually created on the breadboard 38, the result is as shown in FIG. 9B. FIG. 9B is an example, and there are other connection methods. There are many students who are disgusted with electrical and electronic circuits at the educational site because they cannot perform circuit learning intuitively. Teachers are also difficult to teach.

  If a universal board is used, a circuit close to a circuit diagram can be created, but soldering is troublesome. If not, circuit elements may be destroyed at the solder temperature. When soldering is performed, the used circuit elements cannot be used for other circuits, and many circuits cannot be actually created.

  Therefore, various teaching materials have been developed and disclosed for circuit learning. In the teaching material 40 of Patent Document 1, a conductor wire 44 is pasted according to wiring on a sheet 42 on which a circuit diagram is drawn, and only a circuit symbol portion 46 is disconnected (FIG. 10). A circuit can be created by mounting a circuit element 16 on the upper surface and placing a component 50 having a conductor 48 from the terminal of the circuit element 16 to the lower surface on the symbol of the circuit diagram.

  However, the teaching material 40 of Patent Document 1 cannot create another circuit because the conductor wire 44 is directly pasted on the sheet 42 on which the circuit diagram is drawn. Even if it can, it only changes the resistance value of the circuit element 16 at most. Since the conductor wire 44 is affixed on the sheet 42, the jumper wire that was used when the circuit was created with the breadboard 35 or the universal substrate is omitted. The connection between the circuit elements 16 that are essential in the field of electrical and electronic engineering cannot be practiced. Therefore, even if a circuit can be created, it is impossible to experience how the circuit elements 16 are connected to each other through practical training. Since the component 50 is simply placed on the circuit symbol portion 46, it is considered that the learning effect by the experience of creating the circuit is small.

  Patent Document 2 discloses an educational breadboard in which a connection portion is provided on a panel and a block having an electronic element is inserted therein. Moreover, the same connection part as a panel is provided also in the block, and it can also assemble a block in three dimensions.

  However, the breadboard of Patent Document 2 cannot create a circuit according to the appearance of the circuit diagram because the connection portion of the panel is in a lattice shape. Assembling the blocks in three dimensions makes the circuits three-dimensional, making it difficult for beginners to learn electrical and electronic circuits.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a circuit creation kit that can flexibly cope with various circuit diagrams without omitting jumper wires that are on a fred board.

  The circuit creation kit of the present invention includes a sheet on which a circuit diagram is drawn, a circuit element corresponding to the circuit symbol shown in the circuit diagram, a jumper line corresponding to the wiring shown in the circuit diagram, and the sheet Has a hole formed by a board arranged on the front surface and a conductor into which the terminal or jumper wire of the circuit element is inserted, and a state in which the plurality of the holes are short-circuited and arranged as one connection line, The one connection line is provided so as to be insulated from each other, and includes a block that is magnetically attached to the board.

  The block is attached to the circuit symbol shown in the circuit diagram arranged on the front surface of the board or in the vicinity thereof. Multiple terminals of the circuit element corresponding to the circuit symbol of the part to which the block is attached are inserted into holes of one connection line that is different for each terminal, and jumper wires are inserted into holes of one block and other blocks to block A circuit shown in the circuit diagram is created by electrically connecting them.

  Further, the board may be changed to a transparent plate, and the transparent plate may be disposed on the front surface of the sheet. The circuit diagram drawn on the sheet is visually recognized by the transparent plate, and the block is arranged on the transparent sheet. Circuit elements and jumper wires are inserted into the block holes, and the blocks are electrically connected to create the circuit shown in the circuit diagram.

  According to the present invention, a circuit can be easily created according to a circuit diagram. Unlike patent document 1 demonstrated by the prior art, a jumper line is not excluded but the connection of circuit elements can be practiced. You can easily create other circuits by replacing the sheet and changing the position of the block on the transparent base. Compared with Japanese Patent Laid-Open No. 2004-228688, it is possible to deal with various circuits more flexibly.

  A circuit creation kit according to the present invention will be described with reference to the drawings. The circuit creation kit to be described can be used for various circuit creations besides being used as teaching materials. In the description, reference numeral 20 generally indicates reference numerals 20a, 20b, 20c, 20d, and 20e.

  A circuit creation kit 10 of the present invention shown in FIG. 1 includes a sheet 12 on which a circuit diagram is drawn, a transparent plate 14 disposed on the sheet 12, circuit elements 16 and jumper wires 18 constituting the circuit, circuit elements 16 and the like. A block 20 for attaching the jumper wire 18 is included.

  As the sheet 12, paper, a resin sheet, or the like is used. A punch hole 22 may be formed in the sheet 12 so that filing can be performed by binding with a binder. A plurality of sheets 12 for circuit learning can be bound to one binder. The circuit symbol of the circuit diagram preferably also describes the resistance value of the circuit element. It is easier to learn the circuit by describing the explanation of the circuit in the margin of the circuit diagram.

  When the transparent plate 14 is disposed on the sheet 12, a circuit diagram drawn on the sheet 12 can be seen through the transparent plate 14. The transparent plate 14 uses a resin plate, and this plate may be flexible. The thickness of the transparent plate 14 is not particularly limited, and may be a sheet. The transparent plate 14 may be provided with punch holes 22 so that the transparent plate 14 can be bound together with the sheet 12 by a binder. As illustrated in FIG. 2, the transparent plate 14 b may sandwich the sheet 12. In this case, at least the side on which the circuit diagram is visually recognized is made transparent.

  The circuit element 16 corresponds to a circuit symbol shown in the circuit diagram, and includes a resistor, a coil, a capacitor, a diode, a transistor (including an FET and a thyristor), and an IC chip. If there are a plurality of circuit symbols in the circuit diagram, circuit elements 16 corresponding to all the circuit symbols are provided. The circuit element 16 has a resistance value indicated by a circuit symbol. Furthermore, circuit elements 16 having different resistance values may be provided. A circuit can be assembled using circuit elements 16 having different resistance values and the difference can be practiced. When a plurality of sheets 12 are provided, circuit elements 16 are provided so that circuits can be created along the circuit diagrams of all the sheets 12.

  The jumper wire 18 exposes the conductors at both ends of the covered electric wire, and performs circuit wiring. If the resistance value of the conductor is increased, it can be used as a resistance element.

  The block 20 has at least two types of blocks. 3A has a plurality of holes 24 into which the terminals of the circuit elements 16 or the jumper wires 18 are inserted. The hole 24 is formed of a conductor and functions in the same manner as a known connector. As shown in FIG. 3B, when a plurality of holes 24 are short-circuited and arranged in a line, a connection line 26 is provided, and a plurality of connection lines 26 are provided in one block 20a. The connection lines 26 are insulated from each other. In FIG. 3, five holes 24 are provided in one connection line 26, but other numbers may be used. In the block 20a, a plurality of connection lines 26 are arranged in parallel to form a group 27, and the group 27 is arranged in at least two rows. The interval between the connection lines 26 and the interval between the groups 27 are appropriately designed based on the size of the circuit element 16 and the like. The connection line 26 is fixed to a rectangular parallelepiped resin 28.

  A method of using the block 20a and the circuit element 16 will be described. For example, it is assumed that wiring of a circuit diagram as shown in FIG. The wiring shown in the circuit diagram is completed by inserting one terminal of the resistor R and the other terminal into the holes 24 of the different connection lines 26 (FIG. 4B).

  Further, it is assumed that the resistor R and the capacitor C are connected in series as shown in FIG. As shown in FIG. 4D, a resistor R is inserted into one block 20a, and a capacitor C is inserted into another block 20a. The insertion is the same as in FIG. One end of the jumper wire 18 is inserted into the other hole 24 of the connection line 26 having the hole 24 into which the terminal of the resistor R is inserted. The other end of the jumper wire 18 is inserted into the other hole 24 of the connection line 26 having the hole 24 into which the terminal of the capacitor C is inserted. As described above, the resistor R and the capacitor C can be connected in series as shown in FIG. Further, even if the terminals having the resistor R and the capacitor C are inserted into the holes 24 of the same connection line 26 and the other terminals are inserted into the holes 24 of the different connection lines 26, the wiring of the circuit diagram is obtained (FIG. 4). (E)). Wiring is done according to the circuit diagram.

  Another type of block will be described. In the block 20b shown in FIG. 5A, the connection line 26 is fixed to a rectangular parallelepiped resin 28, similarly to the block 20a in FIG. The number of connection lines 26 is three. The three connection lines 26 are insulated and extend in three directions from the vicinity of the center. In the center, the holes 24 at the extreme ends of the three connection lines 26 are arranged. As shown in FIG. 5B, when the terminal of the transistor T is inserted into the three holes 24 and the jumper wire 18 is inserted into the other hole 24, the circuit symbol of the transistor T (FIG. 5C) is matched. Connect. The three connection lines 26 are substantially Y-shaped, and the connection approximates to a circuit symbol when the terminal of the transistor T is inserted. The transistor T can be inserted into the block 20b as the circuit symbol looks. The same applies to FETs and thyristors.

  Although the two types of blocks 20a and 20b have been described, the method of using the blocks 20a and 20b is not limited to the described method. Although it is most preferable that the wiring can be made in the same way as the circuit diagram looks, the circuit element 16 having two terminals instead of the transistor T is used by inserting it into the hole 24 of the connection line 26 which is different for each terminal in the block 20b of FIG. You can also Basically, one circuit element 16 has a plurality of terminals, and it is only necessary to prevent a short circuit between the terminals. If an IC with a large number of terminals is not used, only the block 20b in FIG. 5 may be used.

  The two types of blocks 20 a and 20 b described above connect the circuit elements 16, but a dedicated wiring block that connects only the jumper wires 18 may be provided. For example, when the cross-shaped wiring of FIG. 6A is performed, there is a block 20c of FIG. 6B. The holes 24 described above are arranged in a cross shape, and the holes 24 are short-circuited. Therefore, the connection line 26c has a cross shape. Further, when the T-shaped connection of FIG. 6C is performed, there is a block 20d of FIG. The holes 24 are arranged in a T shape and are short-circuited. The connection line 26d has a T shape. The cross-shaped and T-shaped connections can be made by connecting the jumper wires 18 together with the circuit elements 16 to the connection lines 26 of the blocks 20a and 20b. However, if the blocks 20c and 20d are used, they can be wired intuitively. These blocks 20c and 20d are arranged not on the circuit symbol but on the connection portion of the wiring. One end of the jumper wire 18 is inserted into the hole 24 of the blocks 20c and 20d, and the other end of the jumper wire 18 is inserted into the hole 24 of the other block 20 (shown in FIGS. 3 to 6) for wiring. In addition, although the plurality of holes 24 are arranged in the blocks 20c and 20d, only the hole 24 at the end may be provided.

  The arrangement of the holes 24 has been described by taking straight lines, crosses, and T-characters as an example, but other arrangements may be used according to the circuit diagram, and the shape of the connection line 26 is determined according to the arrangement.

  When the battery 30 is used as the power source, the battery box 32 is used instead of the block 20 in order to attach the battery 30. When using an external power supply, the jumper wire 18 connects the hole 24 of the block 20 to the external power supply.

  The shape of the block 20 is not limited to a rectangular parallelepiped, and includes an arbitrary shape such as a cylindrical shape. If the connection line 26 is fixed to the block 20, the inside of the block 20 is hollow to reduce the weight of the block 20. It is preferable that the block 20 is also transparent so that the circuit symbol can be seen.

  The block 20 is placed on the transparent plate 14. At this time, the circuit symbol of the circuit diagram seen under the transparent plate 14 is seen and placed on or around it. A connecting portion is provided between the block 20 and the transparent plate 14 so that the block 20 does not come off from the transparent plate 14. As the connection portion, a double-sided tape is attached to the lower surface of the block 20 or an adhesive is applied. These connecting portions are preferably those in which the block 20 is not completely fixed to the transparent plate 14 and can be easily removed. Use transparent double-sided tape so that the circuit can be seen.

  The circuit creation will be described. (1) A sheet 12 on which a circuit diagram is drawn is prepared, and a transparent plate 14 is disposed thereon. (2) The block 20 is arranged on the circuit symbol shown in the circuit diagram. Two types of blocks 20a and 20b are selectively used according to the circuit symbol. If the block 20 makes it difficult to see the circuit symbol, the block 20 may be arranged near the circuit symbol (near the circuit symbol). (3) The terminal of the circuit element 16 and the jumper wire 18 are inserted into the hole 24 of the block 20 by the method described above. If the sheet 12 is replaced, other circuits can be formed in the same manner.

  The circuit creation kit 10 is not limited to use in practical training of electric circuits and electronic circuits in universities and technical high schools. You can write a circuit diagram on the sheet 12 yourself and use it to create a circuit.

  Further, the sheet 12 and the transparent plate 14 can be separated, and the circuit can be viewed without a circuit diagram by separating the sheet 12 and the transparent plate 14 after the circuit is created. Depending on the learning method, it can also be expected to improve the understanding of the circuit. If the circuit is prepared, after the steps (1) and (2), the sheet 12 and the transparent plate 14 are separated and the circuit element 16 and the jumper wire 18 are inserted into the holes 24 of the block 20. Is possible.

  The present invention can create a circuit that looks similar to a circuit diagram. Unlike Patent Document 1 described in the prior art, the jumper wire 18 is not excluded, and the connection between the circuit elements 16 can be practiced. If the sheet 12 is replaced and the position of the block 20 on the transparent plate 14 is changed, another circuit can be easily created. Compared with Japanese Patent Laid-Open No. 2004-228688, it is possible to deal with various circuits more flexibly.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the content mentioned above. For example, when a double-sided tape or the like is used on the lower surface of the block 20, there is a possibility that the adhesive effect may be lost due to long-term use or the surface of the transparent plate 14 may be soiled by the adhesive. Therefore, as shown in FIGS. 7A and 7B, a plurality of convex portions 34 are arranged vertically and horizontally at equal intervals on the surface of the transparent plate 14c. The shape of the convex portion 34 is a cylindrical shape, a quadrangular prism, a cone, a pyramid, or the like. The inside of the convex part 34 may be a cavity. As shown in FIGS. 7C and 7D, the concave portions 36 to be fitted with the convex portions 34 are arranged on the lower surface of the block 20e. The block 20e is fixed on the transparent plate 14c by fitting the convex portion 34 and the concave portion 36 as shown in FIG. 7 (e). Since the convex portions 34 are arranged on the entire upper surface of the transparent plate 14c, the degree of freedom of the position where the block 20c is arranged is not impaired, and the block 20e can be arranged according to the circuit symbol of the circuit diagram. The concave portion 36 may be provided in the transparent plate 14c, and the convex portion 34 may be provided in the block 20e.

  As shown in the kit 10b of FIG. 8, the board 15 is used instead of the transparent plate, and the sheet 12 on which the circuit diagram is drawn is arranged on the surface of the board 15 so that the block 20 is attached to the board 15 by the magnetic attraction force. May be. The board 15 may be formed of a ferromagnetic material such as iron, and a resin film may be provided on the surface. A magnet 21 is provided on the bottom surface of the block 20. By attaching the magnets 21 to the four corners or four sides of the bottom of the block 20, the circuit diagram can be visually recognized even when the block 20 is placed on the circuit diagram. If the block 20 is arranged in the vicinity of the circuit symbol in the circuit diagram, a magnet may be provided on the entire bottom surface of the block 20.

  The usage method is as follows: (1) the sheet 12 is arranged on the front surface of the board 15, (2) the block 20 is arranged on or near the circuit symbol of the circuit diagram, and (3) the block 20 is arranged along the circuit diagram. Insert circuit elements and jumper wires. The method of use is almost the same as in the previous embodiment. Moreover, you may attach to the board 15 with a magnet or a tape so that the sheet | seat 12 may not come off.

  The block 20 can be removed by magnetic force, and the arrangement of the block 20 is easy. Further, the board 15 may be made of a magnet, and a ferromagnetic material may be attached to the bottom surface of the block 20.

  In addition, the present invention can be carried out in a mode in which various improvements, modifications, and changes are added based on the knowledge of those skilled in the art without departing from the spirit of the present invention.
