ABSTRACT:
A wire bundle and grommet assembly includes a grommet body with an extension and a retention sleeve that slideably fits over the grommet body extension. Respective stop flanges are spaced from one another. The retention sleeve also includes a one-way ratchet means, and flexible retention fingers engageable with cam ramps on the grommet body extension. When the wire bundle is pulled through the aperture, the grommet body extension and retention sleeve move as one through the aperture, until the retention sleeve stop flange anchors on the bulkhead panel. Thereafter, the grommet body extension slides through the anchored retention sleeve, and the cam ramps flex the retention fingers outboard, past the perimeter of the aperture, and into engagement with one surface of the bulkhead panel. The grommet body stop flange concurrently engages the other surface of the bulkhead panel. The ratchet means keeps the various parts in that position, and the assembly is thereby attached to the bulkhead panel. A compressible gasket may also be provided on the grommet body stop flange to provide a seal.
