Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an electronic circuit construction block assembling apparatus which does not require soldering. More specifically, an electronic circuit assembling block which does not require soldering corresponding to various components and unique elements, and assembles and stores the same. The present invention relates to an electronic circuit component plate and a cover thereof which can be managed, and an electronic circuit component block assembly capable of forming an electronic circuit by inserting blocks for connecting and fixing various electronic elements on the electronic circuit component plate. It is a device.

[0002]

[Prior art]

 Electronic circuit building blocks can be realized by assembling complete electronic circuit blocks without soldering, so they can not only be out of the danger or addiction of the method using soldering, but also interesting. There is also a learning effect by a method called block assembly that can induce interest.

[0003] In recent years, the configuration of electronic circuits has become available to anyone through elementary school curriculum, rather than the proprietary properties of industrial bodies, university laboratories, and minority enthusiasts.

[0004] As a method of configuring an existing electronic circuit, there are an assembling method by soldering, a pin sticking method, a printed circuit board (PCB) processing method, a blood board method, and the like.

[0005] Among the electronic circuit configuration methods, the method most widely used is a method using soldering. This method of assembling by soldering is not only inexperienced in the use of an electric soldering iron, but also because of the toxicity of the smoke of the solder, it makes the construction of the electronic circuit difficult for the mortar. In addition, the electric soldering iron can cause burns, lead poisoning, and classroom pollution due to smoke.The use of power outlets, electric soldering irons, lead wires, nippers, and other tools are all necessary. It is not possible to do it where no element is provided.

[0006] Further, the assembling method by soldering using a printed circuit board (PCB) not only constitutes a single circuit on the board but also makes it difficult to remount it after misplaced and soldered. .

As still another circuit configuration method, a blood board method can be used in a laboratory or as a method that can be performed by a skilled person without soldering.

[0008] However, the blood board method needs to be familiar with the characteristics (direction) of the board and is complicated. In addition, in order to confirm the correct circuit connection, test lines must be separately connected. It has to be fixed easily, and it can easily come off when unskilled people work.

Until now, when assembling an electronic kit using soldering, there is a pleasure to complete one circuit while watching the circuit, but it is very inconvenient to show it to others, or to store and manage it. It was something. Some electronic kits sometimes come with a case, but they cannot be used for other electronic circuits. Therefore, a large number of people sometimes make and use wood, metal plate, acrylic material, etc., but this is still quite inconvenient.

In particular, when several electronic circuits are combined to form an electronic circuit having a composite function, it is difficult to connect the circuits, but considerable effort is required to manufacture the case.

[0011]

[Problems to be solved by the invention]

 Accordingly, the present invention solves the above-mentioned problems by using an electronic circuit assembly block that can be easily understood and configured by anyone who comes into contact with the electronic circuit for the first time and that does not require soldering. In the construction of various large electronic circuits, the completed separate electronic circuit component boards can be connected to other electronic circuit component boards to form a combined circuit having a complex function. An object of the present invention is to provide a circuit configuration block assembling apparatus.

[0012]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention firstly proposes a push-switch type electronic circuit assembly block suitable for the characteristics of various general-purpose devices and a fixed plug type electronic circuit suitable for increasingly various components or unique device characteristics. A circuit assembly block is prepared. A two-pole element such as a resistor and a diode is inserted into a two-pole element block, a three-pole element is inserted into a three-pole element block, and an integrated circuit is inserted into the integrated circuit block.

As described above, since each element is inserted into a block suitable for its characteristics, even a person who comes into contact with the electronic circuit for the first time can easily approach the electronic circuit.

Since the push switch is formed in the concave structure and the copper plate is formed in the protruding structure, the connecting portion to which the electronic element or the circuit connecting line is connected, when the element or the circuit connecting line is inserted, Rarely get out. This facilitates easy use of the shunt and improves the robustness of the completed electronic circuit.

[0015] Further, instead of forming a single fixed circuit such as the printed circuit board (PCB), various circuits can be formed using blocks freely, and are not fixed by soldering. Therefore, even in the case of erroneous assembly, it is easy to take it back, and the reusability of each element is improved even after the completion of the electronic circuit, and it is easy to test after completing the electronic circuit.

In addition, the present invention is to solve the above-mentioned problems of the circuit board, and includes a circuit component board on which an electronic circuit assembly block is mounted, and a circuit board which is connected to the circuit component board and which is easy to store and manage. Provided is a general-purpose circuit configuration board cover.

The circuit component board is a portion for mounting an electronic circuit assembly block to complete an electronic circuit. When the lower end of the assembly block has a protruding portion, the upper portion of the circuit component board has a corresponding concave portion. Conversely, if the lower end of the assembly block has a concave portion, the upper portion of the circuit component board will have a protruding portion.

[0018] The circuit component board cover has a wide open front surface for easy operation because many blocks (operation switch, volume, conversion switch) and the like for circuit operation are located. The side and rear sides are characterized by opening a small area for ventilation and connection of connecting lines.

Also, in order to easily connect each electronic circuit having an individual function, the electronic circuit assembly component boards can be connected by a connecting block.

The connection block has protrusions formed at both ends and a center portion. When the connection block is connected and connected between the connection block grooves of the two circuit boards, the connection block has a twist-free structure. Later, when utilizing, for secure fixation, fix with circuit assembly board connecting block tightening pin using bolt fastening method.
