Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a wiring method for connecting terminals and connection terminals of circuit elements arranged on a substrate using conductive wires.

[Prior art] Conventional wiring methods include using connection wires made of metal materials such as lanes or stranded wires as industrial products, and etching to leave wiring in a predetermined pattern on the board. , seal type method, etc. are being implemented.

[Problems to be Solved by the Invention] In the wiring method using the connecting wire, operations such as twisting, screwing, soldering, and sandwiching the ends of the connecting wire to the terminal of the circuit element or the connecting terminal are required. , and is quite troublesome. Furthermore, the connecting wire must be cut from the winding wire by the required length, and the work of setting and cutting this length is also troublesome.

On the other hand, the etching wiring method requires a wiring pattern plate and special work, and is not suitable for trial production or simple wiring work.

In addition, in the seal type wiring method, although the sealed wire can be pasted on the board, both ends of the sealed wire must be connected to each terminal, which has the same drawbacks as the connection wire described above. .

This invention has been made in view of the above-mentioned circumstances, and an object of the invention is to provide an extremely efficient wiring method that does not require any trouble during wiring and does not require special work for connection. That's true.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides a wiring method for connecting terminals and connecting terminals of circuit elements disposed on a substrate using conductive wires. It is characterized in that the wires are formed by applying conductive paint stored in the vent onto the substrate through the vent.

[Function] By filling a conductive paint in a conductive paint and using this vent to apply a connecting wire on a board in a predetermined wiring pattern, after the coated line dries, it can be used as a connecting wire to connect the terminal of a circuit element. and connect the connection terminals.

[Example] Hereinafter, an example of the wiring method according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, a pen 10 is filled with conductive paint dissolved at a predetermined concentration. As this conductive paint, for example, DOTITEI (trade name, manufactured by Ichikura Kasei Co., Ltd.) is used. this ben 10
By bringing the needle-like pen point 10a into close contact with the surface of the substrate 12 and drawing it around, a line of conductive paint is drawn on the surface of the substrate 12. This wire is then dried to become a conductive wire 14 affixed onto the substrate 12.

By forming the conductive wires 14 in this manner, it is possible to draw a wiring pattern on the substrate 12 in an arbitrary pattern and in a very hour wheel shape, as shown in diagram N2. That is, as shown in the figure, circuit elements 16 .
18.20 terminals 16a, 18a, 20b and tangential terminal 22a.

22b and 22c will be connected to each other by a conductive line 14 drawn on the substrate 12 by Ben 10.

Next, the configuration and operation of the ben 10 used in this wiring method will be explained with reference to FIGS. 3 to 5.

As shown in FIG. 3, the ben 10 includes a cylindrical notebook body 1
・The cap 10c is removable from the pen body 10b to protect the pen tip 10a protruding from the tip of the pen body 10b and to prevent the solvent of the conductive paint from volatilizing. .

The pen body 10b is configured such that its diameter decreases through step portions as it approaches the tip, and the tip surface is opened to a size that leaves a small gap around the pen tip 10a. The pen tip 10a is housed in the pen body 10b so as to be movable along the axial direction, with the negative portion projecting outward from the tip of the pen body 10b.

A sponge body 26 is disposed inside the pen body tob in order to prevent the conductive paint 24 filled therein from flowing out excessively. The aforementioned pen tip 10a passes through this sponge body 26 and is incorporated into the pen body tob. Further, in the middle of this pen tip 10a, a conductive paint 24 is provided.
A presser plate 28 is fixed to determine whether the water flows out or not. This presser plate 28 is capable of coming into contact with the end surface of the stepped portion 10d of the pen body tob.

This presser plate 28 is urged by a coil spring 30 so as to come into contact with the end surface of the stepped portion 10d. This coil spring 3
The rear end of 0 is a spring retainer 32 fixed inside the pen body 10b.
It is locked by.

In this way, when the pen tip 10a is not pressed, the presser plate 28 is moved by the urging force of the coil spring 30.
As shown in FIG. 4, it comes into contact with the end surface of the stepped portion 10d of the pen body tab, thereby preventing the conductive paint 24 from flowing out. - On the other hand, when the pen tip 10a is pressed against the surface of the substrate 12 in order to draw a conductive line on the substrate 12, the pen tip 10a is pushed up against the biasing force of the coil spring 30, as shown in FIG. As a result, the end face of the stepped portion 10d is separated from the presser plate 2B. Therefore, the conductive paint 24 passes through this gap and flows out onto the substrate 12 after its outflow amount is regulated by the sponge body 26. By drawing the pen body 10b around, the conductive paint 24 is drawn on the substrate 12. It will be.

As shown in FIG. 4, a stirring ball 34 is incorporated into the pen body 10b in order to prevent the conductive paint filled therein from solidifying.

According to one embodiment of this wiring method as detailed above,
The wiring work of conductive wires on the board can be accomplished by the work of "writing", and when making circuit wiring prototypes, it can be done in a short time without the need for special tools or equipment. You will be able to do this.

Furthermore, it becomes possible to easily modify the pattern of an existing printed circuit board without requiring any soldering work.

In this way, this wiring method is effective for simple manual wiring of terminals and connection terminals of circuit elements disposed on the surface of the substrate.

Further, the object to be wired is not limited to a substrate having a flat surface, but may have any surface configuration including a flat surface or a curved surface. In short, any surface to which conductive paint can be applied may be used. As described above, this wiring method can be used in any configuration, so its uses are wide-ranging and its industrial applicability is high.

Furthermore, since a pen is used as a means for drawing conductive lines, it is small, lightweight, and convenient to carry.

Moreover, it is as easy to use as a normal felt-tip pen, and has extremely good workability.

[Effects of the Invention] As described in detail above, the wiring method according to the present invention is a wiring method for connecting terminals and connection terminals of circuit elements arranged on a substrate using conductive wires. is characterized in that it is formed by applying conductive paint stored in the pen onto the substrate through a pen. Therefore, according to the present invention, an extremely efficient wiring method is provided that does not require special work for connection, which is time-consuming during wiring.
