Bradford is generally used for educational purposes. Brad board is used by SW (software) or HW (hardware) training course. Brad board is used by beginners and students. As can be seen in FIG. 1, novice users or students should be familiar with the connection configuration of the area of the Brad Board beforehand and should consider the connection of other parts using the jumper wire in a well-known state. This is very difficult for beginners and students.

As described above, since the configuration of FIG. 1 is an internal connection configuration of the Brad board, it can not be intuitively known to the beginner. In addition, Bradboard has many advantages when connecting chips, but in the absence of chips, connecting components is not useful for beginners.

Therefore, there is a need for a Brad board, a Brad board jumper wire, and a training kit that enable novice users to intuitively understand the connection configuration of the Brad board and to facilitate circuit configuration through connection of parts through an intuitive connection configuration.

To achieve the above object, a Brad board includes a metal layer that can be coupled to a magnet, an insulating layer that is located on a metal layer, and a plurality of conductive pads that are located on an insulating layer.

In order to achieve the above object, a jumper wire for a Brad board includes a magnet terminal, a connection line for conducting electric signals with the magnet terminal, and a connection terminal for conducting electrical signals.

In order to achieve the above object, the educational kit includes a jumper wire for a Brad board and a Brad board, wherein the Brad board includes a metal layer connectable to the magnet, an insulating layer located on the metal layer, and a plurality of conductive And the jumper wire for the Brad board includes a magnet terminal, a connection line for conducting electrical signals to the magnet terminal, and a connection terminal for conducting electrical signals.

The above and other objects, features and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings, in which: It can be easily carried out. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a view showing an exemplary external shape of the board 100 according to the present invention.

As can be seen in FIG. 2, the board 100 includes an insulating layer 110 and a plurality of conductive pads 130 located on the insulating layer 110 and disconnected from each other.

Referring to FIG. 2, the insulating layer 110 may be formed of a plastic (plate) including a synthetic resin component. The metal layer 150 may be formed of a plastic Lt; / RTI > Thus, the insulating layer 110 is composed of a component that is not electrically conductive.

The conductive pad 130 is located on the insulating layer 110 and is directly bonded to the insulating layer 110. For example, the conductive pad 130 may be attached directly to the plastic plate of the insulating layer 110 via a bonding material (e.g., an adhesive). Conductive pad 130 is comprised of a highly conductive metal and includes a non-ferrous metal component, such as, for example, copper. The conductive pad 130 may be a copper tape.

As can be seen in FIG. 2, each of the plurality of conductive pads 130 has a strip shape. The conductive pad 130 is configured to conduct electric signals between the components when the circuit of the board 100 is constructed. Thus, the two components connected to one and the same conductive pad 130 can conduct electrical signals to each other, and the electrical signals of the various conductive pads 130 can be conducted through the parts connected to the various conductive pads 130.

The width of the conductive pad 130 may be predetermined. For example, the width of the conductive pad 130 may be determined by a diameter or a size of the magnet terminal 210 of the jumper wire 200 used in the Brad board 100, or a size proportional to the size. Also, the interval between the conductive pads 130 adjacent to each other is set to be larger than the diameter or the surface size of the magnet terminal 210. The length of the conductive pad 130 may vary depending on the design of the board 100. For example, a particular class of conductive pads 130 (the conductive pads 130 in the vertical direction in FIG. 2) may have a longer length than the other class of conductive pads 130 (the horizontal conductive pads 130 in FIG. 2) Lt; / RTI >

The spacing between the conductive pads 130 is greater than the size of the terminals of the jumper wires 200 so that the conductive pads 130 are unintentionally caused to be electrically conductive to each other according to the position at which the jumper wires 200 are placed .

2, the plurality of conductive pads 130 are directly exposed to the user. The user can intuitively know the basic connection configuration of the board 100 through the conductive pad 130. [

3 is a view showing an exemplary cross-sectional view of a board 100 according to the present invention.

3 is a cross-sectional view taken along line AA 'of FIG. As can be seen in FIG. 3, the Bradboy 100 further includes a metal layer 150 therein. As shown in FIG. 3, the insulating layer 110 is located on the metal layer 150 of the Brad board 100. The plastic plate of the insulating layer 110 preferably constitutes a case to protect the metal layer 150 without exposing the metal layer 150 to the outside.

The metal layer 150 includes a metal that can be coupled to the magnet. The metal layer 150 includes a metal component that can be adhered to the magnet and is coupled with a magnet outside the insulating layer 110 to fix the jumper wire 200 according to the present invention to the board 100 . The metal layer 150 may be, for example, a metal containing tin component or an iron metal. The metal layer 150 is preferably embedded in the case of the board 100 in the form of a plate.

As described above, the BradBoard 100 connects the jumper wire 200 having the magnet terminal 210 to the metal layer 150 located below the conductive pad 130 for connecting components to be mounted according to the circuit configuration. .

4 is a diagram showing an exemplary external shape of the jumper wire 200 for a Brad board.

The jumper wire 200 of FIG. 4 is a jumper wire 200 that is available in the Bradboard 100 shown in FIGS.

4, the jumper wire 200 includes a magnet terminal 210, a connection line 230 and a connection terminal 250, and includes a solder 270 for coupling the magnet terminal 210 and the connection line 230 And a metal terminal 290 positioned between the solder 270 and the magnet terminal 210. [

Referring to FIG. 4, the jumper wire 200 for the Brad board 100 according to the present invention will be described. The magnet terminal 210 is made of a magnetic material and has a metal layer 150). The magnet terminal 210 may be formed of, for example, a neodymium magnet. The magnet terminal 210 is formed to have a cylindrical or rectangular parallelepiped shape. The diameter of the magnet terminal 210 or the length of the specific surface of the rectangular parallelepiped is used in setting the width (thickness) and the interval of the conductive pad 130 of the Bradard 100.

The metal terminal 290 is coupled to the magnet terminal 210 so that the electrical signal can be conducted and the solder 270 can be coupled through soldering. The metal terminal 290 preferably has the same shape as the shape of the magnet terminal 210 and is composed of iron components that are easy to conduct and solder electrical signals. The metal terminal 290 may be omitted according to a modification of the jumper wire 200.

The solder 270 provided on the jumper wire 200 couples the connection line 230 and the magnet terminal 210 (directly or via the metal terminal 290) so that the electric signal can be transmitted. The solder 270 is formed through a soldering process. In order to connect the electric wire to the magnet terminal 210, a common lead may be used. However, in order to perform direct soldering to the magnet terminal 210, it is necessary to use lead having a low melting point according to the magnet component of the magnet terminal 210.

For example, in the case of neodymium magnets, magnetism is lost when it exceeds 300 degrees. Accordingly, the soldering for joining the magnetic terminal 210 and the connection line 230 according to the present invention is performed through low-melting point soldering which is melted at a low temperature (for example, 180 degrees). The low-melting point lead can be, for example, lead-free and may be a lead-free lead of a specific Sn-Ag-Cu system. A solder 270 for joining the connection line 230 and the magnet terminal 210 through the low-melting point soldering is formed. A metal terminal 290 to be soldered between the magnet terminal 210 and the solder 270 is inserted into the metal terminal 290 so as to be soldered even in general lead other than the low melting point soldering method, It is also possible to couple the magnet 290 and the magnet terminal 210 together. The metal and magnet can be combined using a shrink tube to join the metal and the magnet.

The connection line 230 conducts an electric signal between the connection terminal 250 and the magnet terminal 210. The connection line 230 preferably includes a soft wire 233 and a light wire 231, as can be seen in FIG. The flexible cable 231 is configured not to bend well and the flexible cable 233 can be changed in shape by the user. The grounding wire 231 is configured to conduct electrical signals between the solder 270 and the softening wire 233 and the softening wire 233 is configured to conduct electrical signals between the connection terminal 250 and the hardening wire 231 do.

The connection terminal 250 is a terminal to be connected to a component to be used in the circuit configuration in the board 100. The connection terminal 250 is connected to the connection line 230 and the terminal of the component to conduct electrical signals. The connection terminal 250 may be a male type male type or a female type female type.

2 and 3 and the one or more jumper wires 200 shown in FIG. 4 can be configured and distributed as an educational kit. This educational kit can be used as a set-up for electrical circuit design training. The training kit includes the Brad board 100 and the jumper wire 200 and may further include other materials.

A user using the educational kit can intuitively sense the connection configuration of the board 100 itself in the shape of the conductive pad 130 of the board 100. [ The magnet terminal 210 of the jumper wire 200 allows the user to conveniently fix the jumper wire 200 to the BradBoard 100 and connect to other components without any connection setup.

The Brad board, the jumper wire for the Brad board, and the education kit according to the present invention can be utilized in various fields. For example, the present invention can be utilized in physical computing education and adoino education, and can be utilized as a training apparatus and can be used for circuit training of an introductory person and education of an embedded system.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. The present invention is not limited to the drawings.
