DISCLOSURE OF THE INVENTION Here, the bus bar 1
For the reason of the circuit design of Nos. 1 and 13, as shown in FIG. 9 or FIG. 10, it may be necessary to arrange a plurality of vertical bus bars 11a, 12a, 13a in parallel. The bus bar wiring board 45 shown in FIG. 9 includes a front surface 21 a and a back surface 2 of the insulating substrate 21.
From the bus bars 11 and 13 respectively arranged on 1b,
Two vertical bus bars 11 are provided on the surface 21a side of the insulating substrate 21.
a and 13a are erected and installed side by side, and the insulating substrate 2
An insulating substrate 23 is further stacked on the front surface 21a side of the No. 1 substrate. Further, the bus bar wiring board 47 shown in FIG. 10 includes two bus bars 11 arranged on the back surface 21b of the insulating substrate 21,
12 and one bus bar 13 arranged on the surface 21a of the insulating substrate 21, three vertical bus bars 11a, 12a, 13a are erected side by side on the surface 21a side of the insulating substrate 21. .

Thus, the plurality of vertical bus bars 11a, 12
When a and 13a are arranged side by side, as shown by the chain line in FIG.
The vertical busbars 11a, 12a, 13a are adjacent to each other only by slightly shifting the bending direction.
3a may contact each other (contact portions P and Q).
For this reason, as shown in FIG.
In the case of arranging a and 13a in parallel, the insulating rib 37 is projected from the upper cover 35 that covers the front surface side of the bus bar wiring board 45, and the upper cover 35 is attached to the under cover 33 that covers the back surface side of the bus bar wiring board 45. In doing so, the insulating rib 37 was inserted between the vertical bus bars 11a and 13a adjacent to each other to ensure the insulating property between the two.

However, in such a structure, when the upper cover 35 is mounted, the insulating rib 37 and the vertical bus bar 1 are attached.
1a and 13a are upper cover 35 and under cover 3
Since it is hidden by 3, it is difficult to insert the insulating rib 37 between the vertical bus bars 11a and 13a. Therefore, the work of mounting the upper cover 35 becomes complicated,
Moreover, when the upper cover 35 is attached, the vertical bus bar 11a,
It was not possible to visually confirm the insulation state between 13a.

If the bending directions of the vertical busbars 11a and 13a are shifted and are close to or in contact with each other, the vertical busbars 11 will be in contact with each other.
If the insulating ribs 37 cannot be easily inserted between the a and 13a and the number of the vertical bus bars 11a and 13a is large, the number of the insulating ribs 37 is correspondingly large, and a plurality of insulating ribs 37 are required. It was difficult to insert the vertical bus bars 11a and 13a at the same time. Therefore, the workability of mounting the upper cover 35 may be deteriorated.

In consideration of the above circumstances, the present invention provides a busbar wiring board which can easily secure the insulation state between adjacent vertical busbars and can easily visually confirm the insulation state of both. With the goal.

In a busbar wiring board in which a plurality of vertical busbars are arranged side by side, an insulating partition to be inserted between the vertical busbars adjacent to each other is projected on the surface side of the insulating substrate. .

A second aspect of the present invention is the bus bar wiring board according to the first aspect, wherein the front surface side of the insulating substrate is:
An insulative vertical busbar accommodating portion is provided to accommodate and cover at least one of the vertical busbars adjacent to each other, and the partition wall is a standing wall of the accommodating portion.

The invention according to claim 3 is the bus bar wiring board according to claim 1 or 2, wherein the partition wall is integrally formed with the insulating substrate.

[0014]

According to the first aspect of the present invention, if the busbars are arranged at regular positions with respect to the insulating substrate, the partition walls are always inserted between the vertical busbars adjacent to each other. The state can be secured by a simple structure and work, and the insulating state of both can be easily confirmed by visual inspection.

According to the invention of claim 2, in addition to the operation of the invention of claim 1, since at least one of the adjacent vertical busbars is accommodated in the vertical busbar accommodating portion, the accommodated vertical busbars are insulated substrates. Since it is not exposed to the surface side of, the insulating property between the vertical bus bars can be further improved.

According to the third aspect of the invention, in addition to the function of the first or second aspect of the invention, since the partition wall is integrally formed with the insulating substrate, the structure can be further simplified.
