Description of the Related Art Conventionally, in a large electric junction box such as a junction block, an internal circuit is generally formed by arranging bus bars formed by stamping a conductive metal plate through an insulating plate and forming an internal circuit.

There is a problem that the cost increases because the bus bar has to be formed according to the circuit change, and as shown in FIG. 5, a part of the internal circuit is connected to the electric wire w and the press contact terminal T for connecting the electric wire w.
And may be used in combination with the bus bar B.
(Japanese Unexamined Utility Model Application Publication No. 2-136989) In some cases, an internal circuit is composed of only the electric wires and the press contact terminals.

型化するには限界があった。However, when the conventional internal circuit is composed only of the bus bar, when it is composed only of the combination of the electric wire and the pressure contact terminal, and when it is composed of the bus bar and the electric wire + the pressure contact terminal. In any case, there is a limit to downsizing a large electric junction box.

寸法精度が出ないためである。[0005] That is, when an internal circuit is composed of only bus bars, the pitch between the tabs provided on the bus bars is at least four.
mm, so that it cannot be used with a connector having a smaller pitch or a small integrated fuse, and the connector and the fuse become larger, and accordingly, the electric connection box itself becomes larger. The reason that the above minimum pitch cannot be set to 4 mm or less is that when punching a conductive metal plate with a large press, the strength of the punch is insufficient, and the punch is broken during mass production.
This is because dimensional accuracy cannot be obtained.

に電線が伸びて組立時に問題が生じる。When an internal circuit is composed of electric wires and crimping terminals, the pitch is determined by the size of the crimping portion. To reduce the size, it is necessary to reduce the crimping terminals or the wire size. If the terminals are made smaller, sufficient contact pressure cannot be obtained, and if the wire size is made smaller, the wires will be stretched at the time of manufacture, causing problems during assembly.

問題がある。However, if a conventionally used bus bar is used as a circuit on the side of the electric junction box connected to the plate-shaped fuse, the tab pitch of the bus bar cannot be reduced as described above. There is a problem that cannot be matched. The above problem is that if the tab to be connected to the adjacent blown body is not formed from the same bus bar, but is formed from a bus bar of a different layer, the internal circuit can be connected to the small integrated fuse even as a bus bar. There are problems such as an increase in the number of busbar layers and an increase in cost, an increase in the size and complexity of the electric junction box, and a lack of flexibility in circuit design of the busbar.

く、電線と十分な接圧力を得ることができる。The small current circuit is an FPC, and the medium current circuit is composed of an electric wire and a press contact terminal. Therefore, the downstream side of the small integrated fuse is connected to the FPC, and the upstream side is connected to the medium diameter electric wire through the connection terminal. In addition, the pitch of the connection terminals on the internal circuit side can be matched with the small pitch of the blown body of the small integrated fuse, and as a result, the small integrated fuse can be attached to the junction block.
At that time, since the core wire of the upstream electric wire has a medium diameter, there is no elongation of the electric wire that occurs when a small-diameter thin wire is used, and there is no possibility that a problem occurs during assembly. Further, since the wire is a medium-diameter wire, the size of the press contact terminal is not so small, and a sufficient contact pressure with the wire can be obtained.
