Abstract
Abstract A potting shell of resilient material is disclosed. The shell has an inwardly directed resilient lip which makes a wiping engagement with a rigid connector housing which is to be potted. The wiping engagement provides efficient sealing so that the previously required adhesives can be omitted. The elastomeric shell assumes sufficient rigidity after potting to become an integral part of the connector.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
144 words
A potting shell of elastomeric material, said potting shell comprising: a series of interconnected walls forming a closed profile that defines an open-ended central chamber, said central chamber having a connector-receiving end and a rearward end, said connector-receiving end being profiled to receive a portion of a rigid connector housing; and a resilient inwardly directed annular flange adjacent said connector-receiving end, said annular flange defining a profile of smaller area than that of said portion of said housing whereby, when said connector-receiving end receives said portion of said housing therein, said annular flange is deflected in a direction away from said connector-receiving end, said annular flange thereby wipingly engaging said portion of said housing as an expandable seal so that potting material introduced into said central chamber from said rearward end is prevented from flowing out of said central chamber at said connector-receiving end.
Claim 2
Dependent Claim
144 words
A potting shell of elastomeric material, said potting shell comprising: a series of interconnected walls forming a closed profile that defines an open-ended central chamber, said central chamber having a connector-receiving end and a rearward end, said connector-receiving end being profiled to receive a portion of a rigid connector housing; and a resilient inwardly directed annular flange adjacent said connector-receiving end, said annular flange defining a profile of smaller area than that of said portion of said housing whereby, when said connector-receiving end receives said portion of said housing therein, said annular flange is deflected in a direction away from said connector-receiving end, said annular flange thereby wipingly engaging said portion of said housing as an expandable seal so that potting material introduced into said central chamber from said rearward end is prevented from flowing out of said central chamber at said connector-receiving end.
Claim 3
Dependent Claim
14 words
A shell according to claim 1 further comprising: latching means engageable with said housing.
Claim 4
Dependent Claim
47 words
A potting shell according to claim 1 further comprising: at least one elongated end portion extending from said shell and having a bore passing therethrough, said bore receiving jack screw means, said end portion retaining its resilient characteristics after said shell is filled with hardened potting material.
Claim 5
Dependent Claim
170 words
In combination with an electrical connector having a rigid housing with a plurality of terminals mounted therein and terminating conductors extending therefrom, a potting shell of elastomeric material, said potting shell comprising: a series of interconnected walls forming a closed profile that defines an open-ended central chamber, said central chamber having a connector-receiving end and a rearward end, said connector-receiving end being profiled to receive a portion of said connector housing enclosing the conductors and terminals; and a resilient inwardly directed annular flange adjacent said connector-receiving end, said annular flange defining a profile of smaller area than that of said portion of said housing whereby, when said connector-receiving end receives said portion of said housing therein, said annular flange is deflected in a direction away from said connector-receiving end, said annular flange thereby wipingly engaging said portion of said housing as an expandable seal so that potting material introduced into said central chamber from said rearward end is prevented from flowing out of said central chamber at said connector-receiving end.
Claim 6
Dependent Claim

Claim 7
Dependent Claim
14 words
A shell according to claim 4 further comprising: latching means engageable with said housing.
Claim 8
Dependent Claim
47 words
A potting shell according to claim 4 further comprising: at least one elongated end portion extending from said shell and having a bore passing therethrough, said bore receiving jack screw means, said end portion retaining its resilient characteristics after said shell is filled with hardened potting material.
