特開２００８−１４１９３０号公報JP 2008-141930 A

特許文献１に記載されているような構成の連結コネクタにより回路基板を接続する際には、回路基板を、それぞれのスルーホールが対応する端子金具の上に配されるように位置決めしてから接続する必要がある。   When connecting a circuit board with a connecting connector having a configuration as described in Patent Document 1, position the circuit board so that each through hole is arranged on the corresponding terminal fitting and then connect the circuit board. There is a need to.

そのため、上記のような構成の連結コネクタを用いて精度よく回路基板の接続を行うには、連結コネクタの端子金具が接続される基板のスルーホールの孔径を大きくしたり、スルーホール間の間隔（ピッチ）を大きくする必要がある。しかしながら、スルーホールの孔径やピッチを大きくすると基板が大型化するうえに、連結コネクタに取り付けられた際に基板がガタつきやすくなるという問題がある。   Therefore, in order to accurately connect the circuit boards using the connecting connector having the above configuration, the hole diameter of the through hole of the board to which the terminal fitting of the connecting connector is connected is increased, or the interval between the through holes ( It is necessary to increase the pitch. However, when the hole diameter and pitch of the through holes are increased, there is a problem that the substrate is enlarged and the substrate is likely to be loose when attached to the connection connector.

本発明は上記のような事情に基づいて完成されたものであって、精度よく回路基板を接続することができる回路構成体および電気接続箱を提供することを目的とする。   The present invention has been completed based on the above circumstances, and an object of the present invention is to provide a circuit structure and an electrical junction box capable of accurately connecting a circuit board.

上記課題を解決するものとして本発明は、スルーホールが形成された第１回路基板と、スルーホールが形成された第２回路基板と、前記第１回路基板および前記第２回路基板を保持する保持部材と、２つの端部が、前記第１回路基板のスルーホールおよび前記第２回路基板のスルーホールにそれぞれ接続される端子金具、前記端子金具の２つの端部を一方の面および他方の面からそれぞれ突出させた状態で保持する台座部、ならびに、前記台座部から連なり前記保持部材に取り付けられる取付部を有する連結コネクタと、を備え、前記保持部材には、前記連結コネクタの前記取付部を取り付けることにより、前記端子金具の一端部を前記第１回路基板のスルーホールに挿通させた状態で、前記連結コネクタを位置決め固定する位置決め部が設けられていることを特徴とする回路構成体である。
また本発明は、前記回路構成体を収容してなる電気接続箱である。 In order to solve the above problems, the present invention provides a first circuit board on which a through hole is formed, a second circuit board on which a through hole is formed, and a holder for holding the first circuit board and the second circuit board. A member, and a terminal fitting in which two end portions are respectively connected to the through hole of the first circuit board and the through hole of the second circuit board, and the two end portions of the terminal fitting are connected to one surface and the other surface And a connecting connector having a mounting portion that is connected to the holding member and is attached to the holding member, and the holding member includes the mounting portion of the connecting connector. By attaching, a positioning portion for positioning and fixing the connecting connector is provided with one end of the terminal fitting inserted through the through hole of the first circuit board. It is a circuit structure according to claim being.
The present invention also provides an electrical junction box containing the circuit structure.

本発明においては、たとえば以下のような手順で回路構成体を組み立てる。第１回路基板を保持部材に取り付けた後、連結コネクタの取付部を保持部材の位置決め部に配置して連結コネクタを保持部材に取りつける。すると、本発明においては、連結コネクタの取付部を保持部材の位置決め部に取り付けることにより、連結コネクタの端子金具の一端部を第１回路基板のスルーホールに挿通させた状態で連結コネクタを保持部材に位置決め固定することができる。次に、第２回路基板のスルーホールを連結コネクタの端子金具の他端部に挿通させて連結コネクタに接続し保持部材に固定すると、回路構成体の組み立てが完了する。その結果、本発明によれば、回路基板を精度よく接続することができる。   In the present invention, for example, the circuit structure is assembled in the following procedure. After the first circuit board is attached to the holding member, the attachment portion of the connection connector is disposed on the positioning portion of the holding member, and the connection connector is attached to the holding member. Then, in the present invention, by attaching the attachment portion of the connection connector to the positioning portion of the holding member, the connection connector is held in the state where one end of the terminal fitting of the connection connector is inserted into the through hole of the first circuit board. Can be positioned and fixed. Next, when the through hole of the second circuit board is inserted into the other end of the terminal fitting of the connection connector, connected to the connection connector and fixed to the holding member, the assembly of the circuit structure is completed. As a result, according to the present invention, the circuit boards can be connected with high accuracy.

本発明は以下の構成としてもよい。
前記保持部材には、前記第２回路基板を取り付ける取付突部が設けられる一方、前記第２回路基板には前記取付突部に挿通される取付孔が設けられ、前記第２回路基板の前記取付孔を、前記連結コネクタが取り付けられた前記保持部材の前記取付突部に挿通させることにより、前記連結コネクタは、前記端子金具の他端部が前記第２回路基板のスルーホールに挿通された状態で前記保持部材に位置決めされる構成であってもよい。
このような構成とすると、第２回路基板も連結コネクタに精度よく接続することができる。 The present invention may have the following configurations.
The holding member is provided with an attachment protrusion for attaching the second circuit board, while the second circuit board is provided with an attachment hole inserted through the attachment protrusion, so that the attachment of the second circuit board is performed. By inserting a hole through the attachment protrusion of the holding member to which the connection connector is attached, the connection connector is in a state where the other end of the terminal fitting is inserted through the through hole of the second circuit board. It may be configured to be positioned on the holding member.
With such a configuration, the second circuit board can also be accurately connected to the connection connector.

前記連結コネクタの前記取付部および前記保持部材の前記位置決め部の少なくとも一方には、前記連結コネクタを前記保持部材に取り付ける取付方向に対して傾斜する傾斜面が形成されていてもよい。
このような構成とすると、連結コネクタの取付部を保持部材の位置決め部に取り付ける際に傾斜面に案内されるので取付作業を円滑に行うことができる。 At least one of the attachment portion of the connection connector and the positioning portion of the holding member may be formed with an inclined surface that is inclined with respect to an attachment direction in which the connection connector is attached to the holding member.
With such a configuration, when the attachment portion of the connection connector is attached to the positioning portion of the holding member, the attachment work can be smoothly performed because the guide portion is guided by the inclined surface.

前記連結コネクタの前記取付部には前記取付方向に対して傾斜する第１傾斜面が形成され、前記保持部材の前記位置決め部には、前記第１傾斜面とは前記取付方向に対して傾斜する角度が相違する第２傾斜面が形成されていてもよい。
第１傾斜面の傾斜角度と第２傾斜面の傾斜角度が同じ場合には、第１傾斜面と第２傾斜面とが面当たりするため、位置決め位置に至る前に止まってしまい、連結コネクタが保持部材に対して傾いた状態で取り付けられることが懸念される。しかしながら上記のような構成とすると、第１傾斜面と第２傾斜面とが面当たりしないので、連結コネクタが保持部材に対して正しい姿勢で位置決めされる。 A first inclined surface that is inclined with respect to the attachment direction is formed in the attachment portion of the connection connector, and the positioning portion of the holding member is inclined with respect to the attachment direction with respect to the first inclined surface. The 2nd inclined surface from which an angle differs may be formed.
When the inclination angle of the first inclined surface and the inclination angle of the second inclined surface are the same, the first inclined surface and the second inclined surface come into contact with each other, so that the connection connector is stopped before reaching the positioning position. There is a concern that it may be attached in a tilted state with respect to the holding member. However, with the above configuration, the first inclined surface and the second inclined surface do not come into contact with each other, so that the connecting connector is positioned in a correct posture with respect to the holding member.

本発明によれば、精度よく回路基板を接続することができる回路構成体および電気接続箱を提供することができる。   ADVANTAGE OF THE INVENTION According to this invention, the circuit structure body and electric junction box which can connect a circuit board accurately can be provided.
