Description

  The present invention relates to an electrical junction box mounted on an automobile or the like, and more particularly to an electrical junction box in which a printed circuit board and a bus bar insulating plate are accommodated in a case in a laminated state.

  In automobiles and the like, electrical junction boxes are employed for the purpose of realizing efficient electrical connection and the like for branch connection of wire harnesses to various electrical components and mounting of control devices such as ECUs. . In this type of electrical junction box, as disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 2000-114739) and the like, a printed circuit board and a bus bar insulating plate are accommodated in a case. In addition, a connector housing portion is formed on the outer wall of the case, and a board terminal connected to the conductor of the printed board and a bus bar terminal connected to the bus bar project from the connector housing portion.

  And the external connector provided in the terminal of the electric wire which comprises an external circuit can be fitted by the connector accommodating part formed in this electrical junction box. By fitting the external connector, the electric wire of the external circuit is connected to the board terminal and the bus bar terminal, and the internal circuit in the electrical connection box is connected to the external circuit.

  By the way, the board terminal in the printed circuit board is generally supported and protruded by a terminal base installed on the printed circuit board. On the other hand, the bus bar terminal is integrally formed at the end portion of the bus bar by bending the end portion of the bus bar disposed and supported by the bus bar insulating plate. Thus, the two (substrate terminal and bus bar terminal) having different basic structures have been conventionally provided with different connector housing portions.

  However, separately forming the board terminal connector housing portion and the bus bar terminal connector housing portion on the outer wall of the electrical junction box requires a large space, which is an obstacle to the compactness of the electrical junction box. It was. In addition, in order to form a plurality of connector housing portions, there is a problem that the outer wall shape of the electrical junction box and thus the structure of the molding die are complicated, making the production troublesome and costly. In addition, when the number of connector housing portions in the electrical junction box increases, the work of fitting and connecting external connectors to each connector housing portion becomes cumbersome, and a lot of time and labor are required for mounting the electrical junction box. There was also a problem.

  In view of this, the present applicant has proposed an electrical junction box in which a bus bar terminal and a board terminal are mixedly provided in one connector housing portion in Patent Document 2 (Japanese Patent Laid-Open No. 2008-35669). In this electrical connection box, a board terminal that is supported by a terminal pedestal on the printed circuit board and protrudes, and a bus bar terminal that protrudes through the printed circuit board at a position away from the board terminal are in one connector housing portion. It is arranged. Therefore, an external circuit can be simultaneously connected to the board terminal and the bus bar terminal by fitting and connecting one external connector to one connector housing portion.

  However, when the inventor further studied the invention described in Patent Document 2 previously proposed by the present applicant, it is necessary to set the bus bar terminal at a position off the terminal base on the printed circuit board. As a result, it was found that the degree of freedom in designing printed circuit boards and bus bars might be limited, and there is still room for improvement.

  The present invention has been made in the background as described above, and the problem to be solved is that the board terminal and the bus bar terminal can be projected in a compact manner in one connector housing, An object of the present invention is to provide an electrical junction box having a novel structure that can sufficiently ensure the degree of freedom of design of a bus bar.

  A feature of the present invention is that a bus bar insulating plate and a printed board are accommodated in a case in a stacked manner, and are provided on a printed circuit board with a bus bar terminal formed by a bus bar placed on the bus bar insulating plate. In the electrical connection box in which the board terminals are arranged so as to protrude from the common connector part, a terminal base is provided on the part of the printed board that is not covered with the bus bar insulation board on the surface on which the bus bar insulation board is placed. The bus bar terminal is formed by protruding the board terminal through the terminal pedestal and extending the bus bar from the bus bar insulating plate onto the terminal pedestal and bending the bus bar on the terminal pedestal. This is because a support seat for supporting the base end portion of the terminal is provided on the terminal base.

  In the electrical junction box having the structure according to the present invention, the bus bar terminal can be supported by the terminal base provided on the printed board and supporting the board terminal. Therefore, it is possible to project the board terminal and the bus bar terminal on the common terminal base with excellent space efficiency, and the electrical connection box can be made compact.

  Moreover, by disposing a bus bar insulating plate on the installation surface side of the terminal pedestal on the printed circuit board, the board terminal and the bus bar are formed on the terminal pedestal without forming a through hole for inserting the bus bar in the printed circuit board. Terminals can be juxtaposed. Therefore, the conductor pattern in the printed circuit board is not limited by the bus bar, and the degree of freedom in designing the printed circuit board can be ensured.

  Further, in the present invention, the support seat portion in the terminal pedestal includes a support surface located on the same plane as the bus bar arrangement surface in the bus bar insulating plate, and the base end portion of the bus bar terminal is provided by the support surface. The supported mode is preferably employed.

  In such an aspect, the end portion of the bus bar that is supported by the bus bar insulating plate and extends in a planar manner can be extended and supported as it is on the same plane as the support seat portion of the terminal base. Therefore, there is no need to perform special bending processing on the bus bar for alignment between the support portion by the bus bar insulating plate and the support portion by the terminal base, and the shape of the bus bar is simplified. Manufacturing is also easy.

  Furthermore, in this aspect, a configuration in which the support surface of the support seat portion in the terminal pedestal is made lower by the thickness dimension of the bus bar than the surface position where the board terminal protrudes is also employed. It is desirable.

  By adopting such a configuration together, the surface of the bus bar placed on the support surface of the support seat portion is positioned on the same plane as the surface of the portion where the board terminal protrudes on the terminal base. I can do it. As a result, when the board terminal and the bus bar terminal are assembled into the insertion hole provided in the bottom wall of one connector housing portion, the bottom wall of the connector housing portion is placed on the support surface as well as the surface of the terminal base. It is possible to overlap and contact the surface of the bus bar. Then, by sandwiching the bus bar between the bottom wall of the connector housing and the support surface of the terminal pedestal, the base end portion of the bus bar terminal can be positioned and supported more firmly with respect to the terminal pedestal.

  Further, in the pedestal connector 20 thus mounted on the printed circuit board 12, the surface 36 of the terminal pedestal 24 spreads out in a plane substantially parallel to the surface of the printed circuit board 12. Then, the terminal portions 28 of the respective board terminals 22 project substantially perpendicularly to the printed board 12 from the surface 36 of the terminal base 24 upward.

  Further, a bus bar support groove 38 is formed on the surface 36 of the terminal base 24. The bus bar support groove 38 is open to the outer peripheral edge of the terminal pedestal 24 and extends inward of the surface 36 of the terminal pedestal 24. In particular, in this embodiment, a bus bar support groove 38 that is linear and has a predetermined width and a predetermined length is employed, and extends from the vicinity of the center of one long side of the terminal base 24 toward the other long side. It is said to be a dead end near the long side.

  An extended end portion 42 of the bus bar 40 supported by the bus bar insulating plate 14 to be described below is fitted into the bus bar support groove 38.

  The bus bar insulating plate 14 has a thin flat plate shape like the conventionally known one, and the bus bar 40 is overlapped and supported on the surface thereof. That is, a bus bar fitting groove 44 having a shape corresponding to the adopted bus bar 40 is formed on the surface of the bus bar insulating plate 14, and the bus bar 40 is fitted into the bus bar fitting groove 44. As a result, the bus bar 40 is mounted on the surface of the bus bar insulating plate 14 on the arrangement surface 46 which is the bottom surface of the bus bar fitting groove 44 and assembled in a positioned state.

  Each bus bar 40 is a plate formed by punching a conductive metal plate or the like, and is provided with a bus bar terminal 48 at an appropriate position on the edge thereof. These bus bar terminals 48 are formed to be bent at a substantially right angle upward on the bus bar insulating plate 14. The base end portion of each bus bar terminal 48 is supported by the bottom wall portion of the bus bar fitting groove 44 formed in the bus bar insulating plate 14.

  As shown in FIGS. 1 to 3, the bus bar insulating plate 14 has a rectangular flat plate shape that is slightly smaller than the printed circuit board 12. As a result, in the board unit 52, the bus bar insulating plate 14 is partially overlapped with the surface of the printed board 12. That is, the printed circuit board 12 has an exposed portion that is not covered with the bus bar insulating plate 14.

  The terminal pedestal 24 is located on the exposed portion of the printed circuit board 12. The terminal pedestal 24 is disposed along the edge of the bus bar insulating plate 14 in the vicinity of the bus bar insulating plate 14.
