Automotive electrical connection box and a method of mounting it
First Claim
1. An automotive electrical connection box, comprising:
- an upper casing having an upper wall with an intermediate portion and a plurality of peripheral sides, at least one sloped surface on the upper wall sloping down from the intermediate portion to at least one of the peripheral sides, an upper surrounding wall extending down from the upper wall at the peripheral sides;
a lower casing having a bottom wall and a lower surrounding wall extending up from the bottom wall, a rib extending up from the bottom wall inwardly from the lower surrounding wall, drainage holes being formed through the bottom wall between the lower surrounding wall and the rib, portions of the bottom wall between the lower surrounding wall and the rib being sloped down to the drainage holes; and
the upper casing being fit on the lower casing so that the upper surrounding wall fits between the lower surrounding wall and the rib and defines a drainage path between the upper and lower surrounding walls for channeling water towards the drainage holes, whereby water is kept away from areas of the bottom wall inward of the rib.

Abstract
An electrical connection box has upper and lower casings (10, 11) for accommodating circuitry. A surrounding wall (10a) of the upper casing (10) fits inside a surrounding wall (11a) of the lower casing (11). Engaging locking claws (10b, 11b) project from the outer surface of the surrounding wall (10a) of the upper casing (10) and from the inner surface of the surrounding wall (11a) of the lower casing (11). An upper wall of the upper casing (10) is inclined down from a center portion to three peripheral edges. A drainage path (13) is defined by a clearance between the surrounding walls (10a, 11a) of the upper and lower casings (10, 11). A bottom wall of the lower casing (11) has drainage holes (14) at the bottom end of the drainage path (13).
