Electrical connection box

摘要

An electrical connection box for a vehicle has bus bars (15a - 15c) providing terminals (17a, 17b) which stand up close to each other, and an insulation plate (16a) through the terminals (17a, 17b) project. A case member (14) covering the insulation plate (15a) provides housing spaces (35) for the terminals (17a, 17b). A partitioning wall (34a) of the casing separating the housing spaces (35) contacts the upper end of an upstanding wall (21a, 22a) of the insulation plate. One of the partitioning wall (34a) and the upstanding wall (21a, 22a) has a recess (26; 42) and the other has a projection (38; 41) received in the recess. This prevents easy liquid passage from one housing space to the other, and minimises risk of current leak between terminals.
