Therefore, if this cordless wiring board device is used, it is not necessary to bundle a plurality of harnesses as in the prior art, and it is not necessary to form a bundled thing along the wiring state, so that it is easy to manufacture a specific wiring structure. It is easy to improve work efficiency. In addition, since the substrate device is a synthetic resin molded product, it can be assembled to a vehicle or the like with a single touch, and the efficiency of the assembly work can be improved.

In this case, if the connector terminal is formed by extending the end of the wiring single wire, it is not necessary to connect the connector terminal to the single wiring wire, so that the connection with the connector is facilitated.

Further, if the connector is inserted into the board member, the connector is integrated with the synthetic resin molded product, so that the handling becomes easy.

Further, even if the connector is integrally formed with the substrate member, the connector is integrated with the synthetic resin molded product, so that the handling becomes easy.

Further, if a grounding metal is connected to the single wire for wiring, and the root part of the grounding metal is inserted into the substrate member together with the single wire for wiring, the grounding metal can also be installed according to the wiring state.

Further, if the mounting member is integrally formed with the substrate member, it is not necessary to separately install the mounting member, so that the mounting operation of the substrate device can be facilitated.

Furthermore, since the manufacturing method of the cordless wiring board device according to the present invention is configured as described above, that is, a state in which a single wire for wiring is formed in a predetermined wiring state and connectors are connected to both ends of the single wire for wiring. Thus, since the formed single wire for wiring is inserted into the synthetic resin substrate member, the cordless wiring substrate device is easily molded into a synthetic resin in accordance with a predetermined wiring state.

    The cordless wiring board device according to the present invention has the most main features in the following configuration when implemented.

As the synthetic resin for molding the “substrate member”, a polyamide-based resin or the like is suitable.

For the “single wire for wiring”, a bare copper wire having a perfect circular cross section is suitable. The portion of the “wiring single wire” forming the connector terminal has a square cross section.

When inserting “wiring single wires” into the substrate member, the required number of “wiring single wires” are positioned in the mold in a state of being separated from each other (by a spacer or the like), and the substrate member is resin-molded. In this case, the molding space of the mold is formed in accordance with the wiring state of the single wire for wiring.

The “connector” can be inserted when the substrate member is formed, or can be integrally formed with the substrate member.

“Earth metal fittings” can also be inserted into the board member. In this case, the “grounding metal fitting” is connected to the single wire for wiring.

When the “cordless wiring board device” is manufactured, a single wire for wiring is formed in a predetermined wiring state, and a connector and a grounding fitting are connected to the single wire for wiring and inserted into the synthetic resin substrate member.
