Abstract
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.

Claim 1
Independent Claim
348 words
A combined wire bundle and grommet assembly attachable to a panel having opposed surfaces so as to pass said wire bundle through an aperture in said panel, comprising, a grommet body having a passage through which a wire bundle extends and within which said wire bundle is held fast with respect to said grommet body, said grommet body further including a stop portion that is sized larger than said aperture and an extension that is sized smaller than said aperture, a cam member on said grommet body extension, a retention sleeve slideably fitted over said grommet body extension and cam member, said retention sleeve being sized smaller than said aperture but for a stop portion sized larger than said aperture and spaced from said grommet body stop portion, a retention member on said retention sleeve that normally lies substantially inboard of said retention sleeve so as to fit through said aperture, but which is movable outboard of said retention sleeve by said cam member when said grommet body extension slides relative to said retention sleeve in an operative direction so as to move said retention sleeve and grommet body stop portions toward one another, whereby, said wire bundle may be pulled through said aperture, thereby pulling said grommet body extension and retention sleeve through said aperture until said retention sleeve stop portion engages one of said opposed panel surfaces, thereby anchoring said retention sleeve with respect to said panel, continued pulling on said wire bundle then serving to slide said grommet body extension relative to said anchored retention sleeve in said operative direction with said relative sliding serving to engage said cam member with said retention member to thereby move said retention member sufficiently outboard of said retention sleeve to move past the perimeter of said aperture and into engagement with the other of said panel surfaces, said relative sliding continuing until said grommet body stop portion also engages said one panel surface, whereby, the engagement of said retention member and said grommet body stop flange with their respective opposed panel surfaces attaches said assembly to said panel.
