Abstract
An attachment bracket for attaching a liquid leakage sensor to a drain opening is provided. The attachment bracket has a funnel-shaped bracket body whose outer circumference is fitted in a liquid-tight relation inside the upper portion of the drain opening, this upper, tapered funnel portion being inclined downwardly toward a central opening leading to the drain. A generally circularly-cylindrical, 'C'-shaped wall member of a prescribed height is installed on the upper funnel surface of the bracket body and extends around the circumference of the central opening of the bracket body except in the region of the opening of the 'C' of the wall member, and a leak detecting sensor is attached to the bracket body within the opening of the 'C' of the wall member. In use, a leak that enters the drain is blocked by the wall member and channelled by the wall member around to the opening of the 'C', thereby concentrating the leak to the region of the sensor location more rapidly than would otherwise occur. In a preferred embodiment, a cap member is positioned over the open top of the 'C'-shaped wall member to further channel and concentrate a leak toward the opening of the 'C' in the wall member.
