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, said trailing sides having a significantly more shallow taper than said lead-in taper surfaces;
wherein a thickness of said outer sealing edge has a dimension C that is employed to derive a plurality of radius values associated with said connection point, said compressive ribs and said notch; and
wherein said seal has a first plurality of intersection points for said plurality of radius values derived from said dimension C such that said first and second plurality of intersection points intersect to position the location of radiuses associated with said connection point, said compressive ribs and said notch, said compressive ribs only being positioned within about a middle section of said seal equal to about one-half of dimension C, 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.

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 surface 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 edges and the opposed faces.

9. A seal that surrounds a wire for precluding entry of contaminants into an electrical connection area, comprising:
a pair of opposed faces having a plurality of wire holes extending therethrough, each of said wire holes having an interior sealing surface that exerts a compressive force on a wire received therein, said interior sealing surface providing a plurality of compressive ribs concentric with said wire hole, said compressive ribs having a notch therebetween that is concentric with said hole at the wire hole, said notch having a diameter less than a diameter of the hole at any point between each of the outermost compressive ribs and their adjacent opposed face, wherein said interior sealing surface has a lead-in taper surface between the outermost compressive ribs and their adjacent opposed face, each said lead-in taper surface extending at least one-quarter of the way in from each said opposed face, wherein said ribs have trailing sides extending to said notch, said trailing sides having a significantly more shallow taper than said lead-in taper surfaces 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. - View Dependent Claims (10, 11, 12, 13)
