ブルプリント基板を用いて、２組の面同士のコネクトを
実現しているが、さらに多くのフレキシブルプリント基
板同士をコネクトしようとした場合には、以下に述べる
問題が生じる。According to the printed circuit board connection configured as described above, two sets of surfaces are connected by using a total of three flexible printed circuit boards. When trying to connect more flexible printed circuit boards, the following problems occur.
【０００７】先ず、多数のフレキシブルプリント基板を

きさのネジ５９とネジ穴５１ｂの深さでは、過大な圧接
力に耐えることができず、ネジ穴５１ｂを破壊してしま
うので、より大きなネジ乃至ネジ穴５１ｂが必要とな
り、大型になってしまう問題点がある。First, in order to hold a large number of flexible printed circuit boards in a pressure contact state to achieve conduction, it is necessary to apply a larger pressure contact force according to the number of the flexible printed circuit boards.
When a large pressure contact force is applied, the connector pressing plate 58 cannot withstand the pressure contact force and is bent between the pressing screws 59. As a result, a sufficient pressure contact force cannot be obtained, resulting in poor contact. In order to prevent this, it is necessary to take some measures such as reinforcement of the connector pressing plate 58, but with the depth of the screw 59 and the screw hole 51b having the above-mentioned sizes, it is possible to endure an excessive pressure contact force. Since it cannot be done and the screw hole 51b is destroyed, a larger screw or screw hole 51b is required, and there is a problem that the size becomes large.

ルプリント基板がコネクト面に対して傾いてしまい面圧
ムラを生じて、圧接不良を起すことになる。A further problem is that the pressure contact force is uneven due to the displacement of the conductor pattern at the pressure contact connection portion. That is, the conductive patterns of the copper foils facing each other are formed to face each other exactly in design, but in reality, they have an error and face each other with a slight deviation. As a result, when a pressing force is applied, the pattern portion of a certain surface is in a state where it is difficult to fit into a concave portion in which a pattern is not formed due to an error of the facing surface, and the flexible printed circuit board tilts with respect to the connection surface, resulting in uneven surface pressure. This will cause defective press contact.

機器においては問題となる。In other words, if a small number of flexible printed boards are stacked, a slight deviation or inclination can be ignored, but if a large number of flexible printed boards are stacked, a large number of flexible printed boards are stacked. Even if the error of (1) is superimposed, it is necessary to prevent the defective press contact. Therefore, it is conceivable to provide a conductive pattern and a gap having a sufficient width on the flexible printed circuit board as a countermeasure for this, but this makes the width of the flexible printed circuit board very large. On the other hand, if the connector is simply divided into several parts and, for example, two connectors are provided, an extra installation area is required, and this is a problem for electronic devices that require miniaturization.

できることも自明である。As a result, the conductive patterns of the copper foil 7a and the back surface copper foil 8a and the front surface copper foil 8b and the copper foil 9a are surely brought into contact with each other, and the electric signal can be transmitted. Therefore, according to the configuration of the first embodiment described above, the pressure applied to each layer can be reduced by dividing one set of the pressure contact connected state into the upper layer and the lower layer. The strength of the connector pressing plate 11 and the like can be prevented from being set to be too large, and the configuration can be simplified. Further, in each layer, the number of the flexible printed boards sandwiched can be reduced, and the defective press contact due to the displacement of the conductive pattern will not occur. Therefore, the width dimension of the conductive pattern of the copper foil and the gap between the patterns can be reduced, and the occupied area can be reduced. Needless to say, the substrates may be directly brought into contact with each other without interposing the substrate having the copper foil patterns on both sides. It is also obvious that the two screws can be eliminated by directly screwing the connector pressing plate 11 onto the base plate of the board.
