Grommet and method of installation on a vehicle
A grommet for a wiring hole comprising an extendable body that is configured in a first sized ring and extendable into a second sized ring larger than the first sized ring, a lip extending around the extendable body and configured to engage a wiring hole for passing one or more wires, and one or more snap locks for locking the extendable body in the extended configuration disposed within the wiring hole on a vehicle.
1. A grommet for a wiring hole, the grommet comprising:
an extendable body that is configured in a first size ring and extendable into a second size ring that is larger than the first sized ring;
a lip extending around the extendable body and configured to engage the wiring hole for routing one or more wires; and
one or more snap locks for locking the extendable body in the second size ring disposed within the wiring hole.
2. The grommet of claim 1 , wherein the extendable body comprises an injection-molded part.
3. The grommet of claim 2 , wherein the extendable body comprises a polymeric material.
4. The grommet of claim 1 , wherein the one or more snap locks comprises a plurality of snap locks.
5. The grommet of claim 4 , wherein a plurality of snap locks comprises a first snap lock and a second snap lock.
6. The grommet of claim 5 , wherein each of the first and second snap locks each comprises a tooth that engages an edge in a locked position.
7. The grommet of claim 1 , wherein the lip comprises an inner lip and an outer lip configured to engage an inside and an outside surface proximate the wiring hole.
8. The grommet of claim 1 further comprising one or more anti-rattle tabs.
9. The grommet of claim 1 , wherein the extendable body has a dimension less than a dimension of the wiring hole.
10. The grommet of claim 1 , wherein the extendable body comprises a first portion, a second portion, and a hinge coupling the first portion to the second portion.
11. The grommet of claim 10 , wherein the hinge flexes to allow the extendable body to move between the first and second sized rings.
12. A vehicle comprising:
a wire;
a wiring hole and;
a grommet comprising:
an extendable body that is configured in a first size ring and extendable into a second size ring that is larger than the first size ring;
a lip extending around the extendable body and engaging the wiring hole;
one or more snap locks for locking the extendable body in the extended second size ring disposed within the wiring hole; and
a central opening, wherein the wire extends through the central opening.
13. The vehicle of claim 12 , wherein the wiring hole is in a metal sheet and the grommet is polymeric.
14. The vehicle of claim 12 , wherein the extendable body comprises a first portion, a second portion, and a hinge coupling the first portion to the second portion, and further wherein the hinge flexes to allow the extendable body to move between the first and second sized rings.
15. The vehicle of claim 12 , wherein a plurality of snap locks comprises a first snap lock and a second snap lock.
16. A method of installing a grommet in a wiring hole on a vehicle, the method comprising the steps of:
providing the grommet having an extendable body that is configured in a first sized ring and extendable into a second sized ring larger than the first sized ring, and a lip extending around the extendable body and configured to engage the wiring hole for routing one or more wires, and further including one or more snap locks for locking the extendable body in the second size ring;
inserting the grommet with the first size ring in the wiring hole in the vehicle; and
extending the size of the grommet ring inside the wiring hole to the second size ring;
locking the grommet in the second size ring with one or more snap locks.
17. The method of claim 16 , further comprising pressing one or more buttons to extend the extendable body from the first size ring to the extended second size ring.
18. The method of claim 16 , further comprising the step of routing a wire or cable through a central opening in the grommet.
19. The method of claim 16 , further comprising the step of molding the grommet as a unitary piece.
20. The method of claim 19 , wherein the grommet is formed of a polymetric material.
