Description

  The present invention relates to an electrical junction box (ie, electric junction) such as a relay box, a fuse box, an electronic control unit box, etc., which is electrically connected to a battery and various electrical components on a vehicle such as an automobile. More specifically, a mounted portion in the vehicle (for example, a mounted surface extending in a direction crossing the extending direction of the vehicle chassis and facing the lower side of the vehicle body panel). In addition, in a fixed state, power is supplied from the battery by electrically connecting a conductive metal terminal that is electrically connected to the conductor of the terminal portion of the electric wire electrically connected to the battery. It relates to an electrical junction box.

  Conventionally, various types of electrical junction boxes have been proposed (see, for example, Patent Document 1).

  Among the various electrical junction boxes, a junction box body fixed to the mounting surface of the vehicle body panel, an electrical component mounting surface provided on the junction box body and mounted with electrical components such as fuses, relays, etc. A conductive metal contact member that can be electrically connected to a conductive metal terminal that is electrically connected to a conductor of a terminal portion of an electric wire electrically connected to the battery, and an electrical component mounting surface; In addition, there is a terminal holding portion that partially exposes and accommodates the contact member so as to allow contact between the contact member and the terminal. As shown in FIG. 4, in the electrical junction box 1 configured as described above, the terminal holding portion 3 is usually provided at the side end of the electrical component mounting surface 2 of the junction box body.

  By the way, as shown in FIG. 5, it is fixed by screwing S to a mounting surface AS that extends in a direction crossing the extending direction HP of the vehicle chassis and faces the vehicle body panel VBP of the vehicle. In this state, a conductive metal terminal (not shown) that is electrically connected to a conductor of a terminal portion of an electric wire (not shown) electrically connected to a battery (not shown) is connected to the terminal. There is a need for an electric connection box used in a vehicle-mounted form in which power is supplied from a battery (not shown) by being electrically connected to the contact member of the terminal holding portion with the portion extending downward. .
