本発明は、移動体としての自動車等に配索される電線の端末に取り付けられる端子金具を備えた電気接続箱に関する。 The present invention relates to an electrical junction box provided with a terminal fitting attached to a terminal of an electric wire routed in an automobile or the like as a moving body.

移動体としての自動車には、一般に、ヘッドランプおよびテールランプ等のランプ類、スタータモータおよびエアコンディショナ用のモータ等のモータ類、等といった多種多様な電子機器が搭載されている。 An automobile as a moving body is generally equipped with various electronic devices such as lamps such as a head lamp and a tail lamp, motors such as a motor for a starter motor and an air conditioner, and the like.

前述した多種多様な電子機器に電力を供給するために、前記自動車にはジャンクションブロックが適宜箇所に配置されている。前記ジャンクションブロックは、多数のヒューズやリレー等の各種の電気回路ユニットを集約して構成されている。 In order to supply electric power to the various electronic devices described above, junction blocks are appropriately arranged in the automobile. The junction block is composed of various electric circuit units such as a large number of fuses and relays.

尚、ジャンクションブロックは、ヒューズ、リレー、バスバー等を有することもあることから、ヒューズブロック、リレーボックス、または総称して電気接続箱とも呼ばれる。本明細書では、前述したヒューズブロック、リレーボックス、ジャンクションブロックを、総称して以下電気接続箱と呼ぶ。 Note that the junction block may include a fuse, a relay, a bus bar, and the like, and therefore is also referred to as a fuse block, a relay box, or an electrical connection box. In the present specification, the above-described fuse block, relay box, and junction block are collectively referred to as an electrical connection box.

電気接続箱は、外郭を形成する箱本体と、端子金具（例えば、特許文献１参照）と、を備えている。箱本体の例えば上面には、前述したリレー、ヒューズやヒュージブルリンク等の電気部品が装着される装着部が複数設けられている。更に、上面には、導電性の板金で構成された被接続部と、該被接続部に螺合した締め付け部材としてのボルトとを設けている。ボルトは、被接続部にねじ込まれることで、その頭の被接続部からの距離が変更される。また、箱本体の例えば下面には、前述した自動車に配索されるワイヤハーネスのコネクタが嵌合する。 The electrical junction box includes a box body that forms an outer shell, and a terminal fitting (see, for example, Patent Document 1). On the upper surface of the box body, for example, a plurality of mounting portions to which the above-described electrical components such as relays, fuses and fusible links are mounted are provided. Furthermore, the upper surface is provided with a connected portion made of a conductive sheet metal and a bolt as a fastening member screwed into the connected portion. The bolt is screwed into the connected part, so that the distance from the connected part of the head is changed. Moreover, the connector of the wire harness routed by the motor vehicle mentioned above fits in the lower surface of a box main body, for example.

ワイヤハーネスは、複数の電線と、該電線の端部等に取り付けられたコネクタとを備えている。コネクタは、前述した自動車に搭載される各種の電子機器や前述した箱本体に嵌合する。更に、箱本体は、前述した装着部に装着される各種の電気部品と、ワイヤハーネスのコネクタの端子とを予め定められたパターンに従って接続するバスバー等を収容している。 The wire harness includes a plurality of electric wires and a connector attached to an end portion of the electric wires. The connector is fitted to various electronic devices mounted on the automobile described above and the box body described above. Further, the box body accommodates a bus bar or the like for connecting various electrical components mounted on the mounting portion described above and the terminals of the connector of the wire harness according to a predetermined pattern.

端子金具は、厚手の導電性の板金からなり、平板状の電気接触部と、電線接続部とを一体に備えている。電気接触部には、前述したボルトのねじ部を通すことのできる孔または切欠きが設けられている。電気接触部は、スライドされることで、孔または切欠き内にボルトのねじ部が通される。そして、電気接触部は、ボルトが前述した被接続部にねじ込まれる等して、該ボルトの頭と前記被接続部との間に挟まれた格好で、前述した箱本体に取り付けられる。 The terminal fitting is made of a thick conductive sheet metal, and is integrally provided with a flat electric contact portion and an electric wire connecting portion. The electrical contact portion is provided with a hole or notch through which the screw portion of the bolt described above can be passed. By sliding the electrical contact portion, the screw portion of the bolt is passed through the hole or notch. The electrical contact portion is attached to the aforementioned box body in such a manner as to be sandwiched between the head of the bolt and the aforementioned connected portion, such as by screwing the bolt into the aforementioned connected portion.

電線接続部は、前述した電気接触部に連なっている。電線接続部は、電源等と接続した電線を加締めるかしめ片等を備えている。電線接続部は、加締め片で電線を加締めて、該電線の芯線と接続する。該電線は、電源と接続している。 The electric wire connecting part is connected to the electric contact part described above. The electric wire connecting portion includes a caulking piece or the like that crimps an electric wire connected to a power source or the like. An electric wire connection part crimps an electric wire with a crimping piece, and connects with the core wire of this electric wire. The electric wire is connected to a power source.

前述した電気接続箱は、電源と接続した電線が取り付けられた端子金具の電気接触部を、前述したボルトにより、前述した箱本体の上面に設けられた被接続部に取り付ける。そして、各装着部に所望の電気部品を装着し、ワイヤハーネスのコネクタを箱本体の下面に嵌合する。こうして、前述した電気接続箱が組み立てられる。そして、電気接続箱は、電源等から供給される電源からの電力を、ヒュージブルリンク、ワイヤハーネスの電線、等を介して前述した電子機器に供給する。 In the electrical connection box described above, the electrical contact portion of the terminal fitting to which the electric wire connected to the power source is attached is attached to the connected portion provided on the upper surface of the box body described above by the bolt described above. Then, a desired electrical component is mounted on each mounting portion, and the connector of the wire harness is fitted to the lower surface of the box body. Thus, the electrical junction box described above is assembled. The electrical junction box supplies power from a power source supplied from a power source or the like to the electronic device described above via a fusible link, an electric wire of a wire harness, or the like.

この電気接続箱は、端子金具のブリッジ部を内側から係止するための可撓性係止部を備えているが、ボルト締結時に該ボルトの回転に伴う端子金具の回転によって可撓性係止部が破損してしまう可能性がある。 This electrical junction box is provided with a flexible locking portion for locking the bridge portion of the terminal fitting from the inside, but when the bolt is tightened, the flexible locking portion is provided by the rotation of the terminal fitting accompanying the rotation of the bolt. The part may be damaged.

また、この電気接続箱は、箱本体を小型化するために、前述した端子金具の電線接続部を前記電気接触部から立設させるとともに、箱本体の外壁面から凹の凹溝を設けて、該凹溝内に電線接続部と該電線接続部に接続された電線とを収容することが考えられる。この場合、前述した孔または切欠き内にボルトのねじ部を挿入するための電気接触部の挿入方向と、該電気接触部と電線接続部とが並ぶ方向とが互いに直交する場合が考えられる。 In addition, in order to reduce the size of the box body, the electrical connection box is provided with the above-described terminal fitting electric wire connection portion standing up from the electrical contact portion, and provided with a concave groove from the outer wall surface of the box body, It is conceivable to accommodate the electric wire connecting portion and the electric wire connected to the electric wire connecting portion in the concave groove. In this case, the case where the insertion direction of the electrical contact portion for inserting the screw portion of the bolt into the hole or notch described above and the direction in which the electrical contact portion and the wire connection portion are arranged may be orthogonal to each other.

この場合、前述した電気接触部をスライドさせる際に、作業員が電気接触部の前述した孔または切欠きの近傍を押圧することとなる。すると、電気接触部の前述した孔または切欠きの近傍に作業員の手袋の繊維等が付着して、電気接触部即ち端子金具と被接続部との導通が不十分になる可能性がある。また、電気接触部が平板状に形成されているため、作業員が該電気接触部をスライドさせにくく、該電気接触部即ち端子金具を前述した被接続部に取付けにくくなる可能性がある。 In this case, when the above-described electrical contact portion is slid, an operator presses the vicinity of the above-described hole or notch of the electrical contact portion. Then, there is a possibility that the fibers of the operator's gloves adhere to the vicinity of the aforementioned hole or notch of the electrical contact portion, and electrical connection between the electrical contact portion, that is, the terminal fitting and the connected portion may be insufficient. Further, since the electrical contact portion is formed in a flat plate shape, it is difficult for an operator to slide the electrical contact portion, and it may be difficult to attach the electrical contact portion, that is, the terminal fitting to the connected portion.
