초록 ▼

A wire harness assembly includes a housing defining an interior volume which extends into the housing along an axis and also defines an outer surface having a retention protuberance extending outward therefrom. A seal is received within the interior volume and a wire extends through the seal into the interior volume. A seal includes skirt segments which extend from the seal retainer wall such that each of the skirt segments is positioned laterally to the outer surface and such that one of the skirt segments is a lock arm having a lock aperture which captures the retention protuberance therein, thereby retaining the seal retainer to the housing. A flex limiting strap joins the lock arm to an adjacent one of the skirt segments and limits the extent to which the lock arm flexes away from the axis.

1. A wire harness assembly comprising: a housing defining an interior volume which extends into said housing along an axis, said interior volume having an interior surface having an interior perimeter, said housing also defining an outer surface having a retention protuberance extending outward therefrom;a seal received within said interior volume which engages said interior perimeter of said interior surface, said seal having a wire aperture extending therethrough;a wire extending through said wire aperture of said seal such that said wire aperture circumferentially engages said wire; anda seal retainer having a seal retainer wall which traverses said axis and which retains said seal within said interior volume, said seal retainer also having a seal retainer skirt which is defined by a plurality of skirt segments which extend from said seal retainer wall such that each of said plurality of skirt segments is positioned laterally to said outer surface; wherein one of said plurality of skirt segments defines a lock arm having a lock aperture which captures said retention protuberance therein, thereby retaining said seal retainer to said housing and limiting motion of said seal retainer relative to said housing along said axis, said lock arm being resilient and compliant which allows said lock arm to flex away from said axis, thereby allowing said lock arm to lift over said retention protuberance when said seal retainer is being installed on said housing and when said seal retainer is being removed from said housing, said seal retainer having a flex limiting strap joining said lock arm to an adjacent one of said plurality of skirt segments which limits the extent to which said lock arm flexes away from said axis. 2. A wire harness assembly as in claim 1, wherein said flex limiting strap is a first flex limiting strap joining said lock arm to a first adjacent one of said plurality of skirt segments, said seal retainer also having a second flex limiting strap joining said lock arm to a second adjacent one of said plurality of skirt segments such that said first flex limiting strap and said second flex limiting strap limit the extent to which said lock arm flexes away from said axis. 3. A wire harness assembly as in claim 1, wherein: said lock arm is flexible between a free state in which said retention protuberance is captured within said lock aperture and a flexed state in which said retention protuberance is not within said lock aperture; andsaid flex limiting strap as viewed in a direction parallel to said axis when said lock arm is in said free state has a first portion that is concave facing toward said axis. 4. A wire harness assembly as in claim 3, wherein said flex limiting strap as viewed in a direction parallel to said axis when said lock arm is in said free state also has a second portion that is concave facing away from said axis and a third portion that is concave facing away from said axis such that said first portion is located between said second portion and said third portion. 5. A wire harness assembly as in claim 4, wherein when said lock arm is in said flexed state, at least one of said first portion, said second portion, and said third portion is distorted compared to when said lock arm is in said free state. 6. A wire harness assembly as in claim 3 wherein when said lock arm is in said flexed state, said first portion is distorted compared to when said lock arm is in said free state. 7. A wire harness assembly as in claim 1, wherein said flex limiting strap is a pleat which expands when said lock arm flexes away from said axis and which contracts when said lock arm returns toward said axis. 8. A wire harness assembly as in claim 1, wherein: said flex limiting strap has a first wall thickness in a direction normal to said axis; andsaid lock arm has a second wall thickness in a direction normal to said axis such that said first wall thickness is less than said second wall thickness. 9. A wire harness assembly as in claim 1, wherein said flex limiting strap limits the extent to which said lock arm flexes away from said axis so as to not exceed an elastic limit of said lock arm.
