As shown in FIG. 7, the structure in which the groove 21 is provided in the insulating substrate 20 and the bus bar 23 is press-fitted is disclosed. However, in this case, the ribs 22 and 22 'forming the groove wall are scraped by the edge of the bus bar 23, and the shavings 24 remain in the groove 21, so that the bus bar 23 may be in a semi-fitted state. However, a long bus bar requires a great deal of force for press fitting. In addition, actual development Sho 60-8
In the 9722 publication, as shown in FIGS. 8 and 9, the locking claw 2 is attached to the bus bar 23.
A structure has been proposed in which 5 is provided and the locking claw 25 is press-fitted into an insulating substrate (not shown). However, in this case, when the bus bars 23, 23 'are arranged side by side and punched out from the conductive plate, the bus bar 23' needs to have a relief 26 for the locking claw 25, resulting in a narrow circuit width and a stamping process. There is trouble such as increase.

バー2,2′…の圧入に備えて屑収容溝８を設けておく。In FIGS. 1 to 5, reference numeral 1 denotes a busbar wiring board, which is composed of a plurality of busbars 2 and 2'and an insulating substrate 5 having a groove 6 for accommodating them. The bus bars 2, 2 '... are formed to have a desired pattern by punching and bending a conductive plate, and tab-shaped connection terminals 4 as branch conductive paths are erected and connected to the end portions or intermediate portions thereof. ing. The groove 6 is formed by vertically arranging the enclosing rib 7 corresponding to the pattern of each bus bar 2, 2 ′ on the insulating substrate 5.
It may be recessed upward. The width w 0 of the groove 6 is larger than the bus bar width w 1 and smaller than the outer diameter W 2 of the press-fitting pieces 3, 3 on both sides. Alternatively, a scrap storage groove 8 is provided in the press-fitting portion of the press-fitting piece 3 of the groove 6 in preparation for press-fitting of the bus bars 2, 2 '...

に対応して適宜箇所に１組または２組以上設ける。The press-fitting piece 3 is made to project from the side edges of the busbar by about 1 / 2t to 1 / 3t, which is smaller than the thickness t of the busbar, by punching out the busbars 2, 2 '... . Also,
The press-forming pieces 3 are formed in one position or in two or more positions at appropriate positions corresponding to the length of each bus bar.

行われる。圧入片３の非形成部分は、第５図のように、
ブスバーとリブ７間に隙間があるから、比較的小さな力
で圧入できる。The bus bars 2, 2 '... Are fixed to the insulating substrate 5 by press-fitting the press-fitting pieces 3, 3 into the groove 6, as shown in FIG. The non-formed part of the press-fitting piece 3 is, as shown in FIG.
Since there is a gap between the bus bar and the rib 7, it can be pressed in with a relatively small force.

の妨げのおそれはなくなる。Since the press-fitting piece 3 is formed thinner than the busbars 2, 2 '..., it has a little flexibility elasticity and is elastically press-fitted into the groove 6, which also contributes to reducing the press-fitting force. The amount of shavings 9 generated is smaller than in the conventional example (see FIG. 7). Further, since the waste storage groove 8 is provided, the shavings 9
Even if it occurs, it is dropped and accommodated at the same time as the press-fitting, and there is no risk of obstructing the press-fitting of the bus bar.
