Abstract

A seal for disposition between a connector and a wire includes opposed faces having at least one wire hole therethrough, an outer sealing surface connecting said opposed faces and contacting the connector, said at least one wire hole having at least two inwardly extending compressive ribs contacting an outer surface of the wire wherein the ribs have a notch therebetween. The inwardly extending compressive ribs each have a contacting apex extending from lead-in side surfaces which extend from the respective opposed faces, and the notch has a diameter less than a diameter of a connection point between the lead-in side surfaces and the opposed faces.

Claims

1. A seal for disposition between a connector housing and a wire, comprising:

opposed faces having at least one wire hole therethrough;

an interior sealing surface connecting said opposed faces to form said at least one wire hole;

said interior sealing surface having at least two inwardly extending compressive ribs contacting an outer surface of the wire, said ribs having a notch therebetween, said inwardly extending compressive ribs having a contacting apex, each said rib having trailing sides that extend from said apex toward said notch, each said outermost rib having lead-in side surfaces extending toward said opposed faces, said notch having a diameter less than a diameter of the hole at a connection point between said lead-in side surfaces and said opposed faces, wherein said at least one wire hole has a seal opening with a diameter greater than the diameter of the hole at said connection point to form lead-in taper surfaces, each said lead-in taper surface extending at least one-quarter of the entire thickness of the seal in from each said opposed face to said connection point, said trailing sides having a significantly more shallow taper than said lead-in taper surfaces.

2. The seal according to claim 1, wherein the seal is made of an elastomeric material having a durometer hardness that allows deflection of said compressive ribs as the wire passes through said wire hole without said compressive ribs remaining in contact with said lead-in taper surfaces upon completion of wire insertion.
