Abstract

An object of the present invention is to provide an electrical connection box in which reduction in weight can be achieved by simplification of the construction, while preventing short-circuiting of a positive electrode side busbar and a negative electrode side busbar. An electrical connection box includes: a positive electrode side busbar connected to a positive electrode of a battery; a negative electrode side busbar connected to a negative electrode of the battery; and a case in which the positive electrode side busbar and the negative electrode side busbar are accommodated. The case includes: a bottom wall; a circumferential wall erected from the bottom wall; and a partition wall erected from the bottom wall. The partition wall is a waterproof partition that partitions a positive electrode side busbar accommodating area and a negative electrode side busbar accommodating area.

First claim

The invention claimed is:

1. An electrical connection box comprising:
a positive electrode side busbar connected to a positive electrode of a high voltage battery;
a negative electrode side busbar connected to a negative electrode of the high voltage battery; and
a case in which the positive electrode side busbar and the negative electrode side busbar are accommodated, wherein
the case includes a bottom wall, a circumferential wall erected from the bottom wall, and a partition wall erected from the bottom wall,
the circumferential wall is provided with a pair of wall portions facing each other, and the partition wall is provided between the pair of wall portions,
a positive electrode side busbar accommodation area in which the positive electrode side busbar is accommodated and a negative electrode side busbar accommodation area in which the negative electrode side busbar is accommodated are partitioned over the entire circumference by the partition wall and the circumferential wall,
the partition wall is a waterproof partition wall that partitions the positive electrode side busbar accommodation area in which the positive electrode side busbar is accommodated and the negative electrode side busbar accommodation area in which the negative electrode side busbar is accommodated,
the case includes a plurality of busbar attachment walls erected from the bottom wall,
each of the plurality of busbar attachment walls extends along with a side of the positive electrode side busbar or the negative electrode side busbar, and
a height of each of the plurality of the busbar attachment walls is higher than a thickness of the positive electrode side busbar or the negative electrode side busbar, and is lower than a height of each of the circumferential wall and the partition wall.

2. The electrical connection box according to claim 1 , wherein an upper end of the partition wall is positioned above an upper end of the circumferential wall.
