  • Patent number: 5545854
    Abstract: A novel grommet assembly for securely sealing a wire harness or cable to an automotive panel opening is achieved with separate, identical grommet halves whose components are axially assembled. The assembled grommet halves are radially mated over the cable and lockingly inserted into the dash panel opening to provide an airtight seal between the cable and the opening. The grommet assembly includes rigid inner and outer shell portions which are axially locked to sandwich a resilient seal therebetween. The seal essentially fills the space between the inner and outer shells, and is both axially and radially compressed upon assembly of the grommet halves, and further when the grommet halves are mated over the cable. The compressive forces on the seal ensure a secure, airtight sealing interface with the cable, between the components of the grommet assembly, and with the dash panel.

  • Patent number: 5537714
    Abstract: A plastic grommet for use on metal studs in wall construction protecting wires, cabling, conduit, and the like. The grommet also makes the passing of such utilities easier and quieter. The grommet will function singularly or assembled to a clone. The grommet includes a cylindrical body having an enlarged flange on one end with radially projecting spring snaps on the exterior of the body whereby the grommet may be inserted in a sized hole in the web with the hole edge captured between the snaps and flange. On the other side of the flange are diametrically opposed axially projecting spring fingers. The flange also has two diametrically opposed holes, the fingers and holes being positioned so that two grommets can be joined flange-to-flange by axially rotating one with respect to the other. Two such grommets thus assembled on opposite sides of a rectangular or other irregular or pre-punched hole in the stud web capture the web between the flanges.
