Abstract

An electrical connection box includes a fusible link including a pair of terminal portions, a plate-shaped conductive member, a first nut including a first flange portion and fastened to the conductive member by being screwed with a first screw member, a second nut including a second flange portion and fastened to the conductive member by being screwed with a second screw member, and a block that includes a holding portion holding the first flange portion and the second flange portion and holds the fusible link. The holding portion extends between the pair of terminal portions in a projecting direction of the terminal portions, and includes a first holding portion located on a back side in an insertion direction, a second holding portion located on an entrance side in the insertion direction, and a projecting portion allowing entry of the first flange portion and restricting entry of the second flange portion.

First claim

What is claimed is:

1. An electrical connection box comprising:
a fusible link that includes a pair of terminal portions facing each other;
a plate-shaped conductive member that is electrically connected to one of the terminal portions;
a first nut that includes a first flange portion and that is fastened to the conductive member by being screwed with a first screw member;
a second nut that includes a second flange portion and that is fastened to the conductive member by being screwed with a second screw member; and
a block that includes a holding portion holding the first flange portion and the second flange portion and that holds the fusible link, wherein
the holding portion extends between the pair of terminal portions in a direction in which the terminal portions project,
the holding portion includes an insertion port into which the first flange portion and the second flange portion are inserted, a first holding portion that is located on a back side in the direction of the insertion and that holds the first flange portion, and a second holding portion that is located on an entrance side in the direction of the insertion and that holds the second flange portion,
at least one of a thickness and a width of the second flange portion is larger than that of the first flange portion, and
the holding portion includes a projecting portion that allows the first flange portion to enter the first holding portion, and that abuts on the second flange portion to restrict the second flange portion from entering the first holding portion.

2. The electrical connection box according to claim 1 , wherein
the thickness of the second flange portion is larger than the thickness of the first flange portion,
the projecting portion projects in the thickness direction of the first flange portion and the second flange portion, and is provided in the first holding portion in the direction of the insertion, and
the projecting portion supports the first flange portion from a side opposite to the conductive member in the thickness direction.

3. The electrical connection box according to claim 1 , wherein
the width of the second flange portion is larger than the width of the first flange portion,
the projecting portion projects in the width direction of the first flange portion and the second flange portion, and is provided in the first holding portion in the direction of the insertion, and
the projecting portion pinches the first flange portion in the width direction to hold the first flange portion.

4. The electrical connection box according to claim 1 , wherein
the conductive member includes a first fixing portion to which the first nut is fastened, and a second fixing portion that is parallel to the first fixing portion and to which the second nut is fastened, and
the conductive member has a curved portion between the first fixing portion and the second fixing portion.

5. The electrical connection box according to claim 2 , wherein
the conductive member includes a first fixing portion to which the first nut is fastened, and a second fixing portion that is parallel to the first fixing portion and to which the second nut is fastened, and
the conductive member has a curved portion between the first fixing portion and the second fixing portion.

6. The electrical connection box according to claim 3 , wherein
the conductive member includes a first fixing portion to which the first nut is fastened, and a second fixing portion that is parallel to the first fixing portion and to which the second nut is fastened, and
the conductive member has a curved portion between the first fixing portion and the second fixing portion.

7. The electrical connection box according to claim 1 , wherein
the block includes an electric wire holding portion configured to hold an electric wire led out from an electronic component held by the block, and
the electric wire holding portion includes a restricting portion that is located between a terminal fastened to the conductive member and the electric wire, and that restricts the terminal from rotating toward the electric wire.

8. The electrical connection box according to claim 2 , wherein
the block includes an electric wire holding portion configured to hold an electric wire led out from an electronic component held by the block, and
the electric wire holding portion includes a restricting portion that is located between a terminal fastened to the conductive member and the electric wire, and that restricts the terminal from rotating toward the electric wire.

9. The electrical connection box according to claim 3 , wherein
the block includes an electric wire holding portion configured to hold an electric wire led out from an electronic component held by the block, and
the electric wire holding portion includes a restricting portion that is located between a terminal fastened to the conductive member and the electric wire, and that restricts the terminal from rotating toward the electric wire.

10. The electrical connection box according to claim 4 , wherein
the block includes an electric wire holding portion configured to hold an electric wire led out from an electronic component held by the block, and
the electric wire holding portion includes a restricting portion that is located between a terminal fastened to the conductive member and the electric wire, and that restricts the terminal from rotating toward the electric wire.
