Abstract

Water is prevented from entering an electric connection box by providing an additional cover with a drain port out of register with drain ports on a normally-provided bottom cover. Baffles between the drain ports on the bottom cover and the drain port on the additional cover provide additional protection.

Claims

1. An electrical connection box, comprising:

a first cover having a first drain port, attached to one side of said electrical connection box;

an auxiliary cover removably attached to said first cover and having a second drain port, said second drain port being disposed out of register with said first drain port, said first cover being disposed between said electrical connection box and said auxiliary cover; and

a baffle plate formed on said first cover so as to intersect a line between said first and second drain ports, thus preventing water from advancing in a straight line from said second drain port toward said first drain port, wherein said baffle plate extends substantially perpendicularly from said first cover at a location between said first and second drain ports.
