Abstract:
A grommet configured to receive a corrugated tube having alternating circular ridges and troughs on an outer periphery of the corrugated tube and configured to be directly mounted in an opening in a panel, the opening having parallel edges, said grommet comprising:a body having a recess around at least part of an outer peripheral surface thereof and an insertion aperture into which the corrugated tube is insertable, said recess including tapered portions and being engageable with an opening having parallel edges provided in a panel; at least one alternating trough and ridge provided in an inner peripheral surface of said body around said insertion aperture, said trough and ridge respectively being engageable with one of the circular ridges and troughs of the corrugated tube, a tongue provided on a surface of said body and extending from an edge of the insertion aperture, the corrugated tube being securable to said tongue by a wrapping tape; said body having a slit extending from said insertion aperture to the outer peripheral surface of the body so that said slit can be opened to easily insert the corrugated tube and closed around the corrugated tube; facing surfaces of said body on opposite sides of said slit being inclined at a predetermined angle with respect to a line within a plane coextensive with an axis of said insertion aperture; and said tapered portions being inclined at about the predetermined angle with respect to the line so that, when said grommet is not mounted on the panel, said slit is openable for easy insertion of the corrugated tube within said insertion aperture, and when said grommet is mounted in the opening in the panel, said tapered portions engage the parallel edges to force said tapered portions parallel, so that said slit is closed by a force generated by engagement of said tapered portions with the parallel edges so that said facing surfaces tightly contact each other to provide watertight engagement.
