Description

  The present invention relates to an electrical junction box and a method for assembling the electrical junction box. More specifically, in an electrical junction box for vehicles, the electrical junction box is improved by improving the connection between an internal circuit and an external circuit in a connector provided in the electrical junction box. The size is reduced.

  Conventionally, in this type of on-board electrical junction box, a bus bar is alternately laminated with an insulating plate inside a case, and a terminal (so-called tab terminal) that protrudes by bending a part of the bus bar is connected to the case. It protrudes into the terminal insertion hole of the connector housing part formed on the wall surface such as the upper wall of the wire, and is fitted and connected to the terminal in the connector of the electric wire terminal that fits in the connector housing part. The electric wire that becomes the circuit is connected.

However, if the internal circuit of the electrical junction box is constituted only by the bus bar and is a terminal protruding from the connector housing portion, the terminal is small in the connector due to the width of the bus bar constituting each circuit and the clearance between the circuits. In many cases, it cannot be projected at a pitch, and therefore, it is often difficult to make one connector housing portion multipolar. In that case, the bus bars are multi-layered and the terminals protrude into the connector housing portion at a predetermined pitch, but the bus bars are multi-layered, the thickness of the electrical connection box increases, and the number of components increases and the bus bar interlayer connection also increases. There are problems such as being necessary.
If the multi-layer structure is not used, the terminals 2 cannot be protruded from the bottom surface 1a of the connector housing portion 1 at a constant pitch. Therefore, as shown in FIG. There is a problem.

  In response to the above problem, for example, the present applicant has disclosed in Japanese Patent Application Laid-Open No. 2002-64920 (Patent Document 1) that, as shown in FIG. 8, the terminal 4 is formed separately, and the terminal 4 is preliminarily molded or the like. A connector provided with an integrated shared part 5 and welding the leg 4a of the terminal 4 protruding from the shared part 5 to the bus bar 6 in the case, while penetrating the shared part 5 through the cover 7 of the electrical junction box It fits in the bottom surface in the accommodating wall 7a, and is fitted with the connector G of the electric wire end.

According to the configuration of Patent Document 1, since the terminals are provided separately from the bus bar 6 by bending and are welded to the bus bar 6 at a required position, the terminals of the connector are arranged at a constant pitch. It can be.
However, since it is necessary to weld the bus bar and the terminal as a separate body without integrating them, there is a problem that it takes a lot of work. And since the separate terminal is connected only to the bus bar, it is also constrained by the width and clearance of the bus bar and does not contribute to narrowing the terminal pitch in the connector. The number of terminal connection points cannot be increased.

  In Japanese Patent Laid-Open No. 2000-114739 (Patent Document 2), as shown in FIG. 9, the tab terminal 6a provided on the bus bar 6 protrudes from the connector accommodating portion 7a of the cover 7, and the bus bar 6 and the insulating plate The electronic circuit boards (sub circuit boards) 8A and 8B are arranged vertically opposite to the main wiring board made of the laminated body and the connector portions 9A and 9B provided on the electric circuit boards 8A and 8B. It protrudes through the wiring board and through the opening 7 b of the cover 7.

In Patent Document 2, a sub circuit board made of an electric circuit board is housed together with a main wiring board made of a bus bar in an electric junction box, so that in addition to the connector housing portion 6a for connecting the bus bar and an external circuit, the sub circuit An opening 7b is provided in the cover 7 to project the board connector portions 9A and 9B.
Thus, if the bus bar connector and the board connector are provided separately, the cover 7 needs to be enlarged, and the electrical junction box becomes larger. Also, when connecting a power supply side terminal made up of a bus bar terminal and a signal terminal made up of a board side terminal to one electrical component via one wire harness, the connector connected to the bus bar side and the board side Since the connector to be connected is different, the connector and the electric wire are required separately, which increases the number of parts and increases the assembly process.
