Abstract
Abstract A process for making R. F. shielded cable connector assemblies and the products formed thereby is described. The process basically comprises the steps of: potting wires of a shielded cable between the cable shield and a connector housing to fill in, support, rigidize and insulate the individual wires contained in the cable; coating the thusly formed potting with an electrically conductive material so as to form an entirely encompassing adhering conductive path between the cable shield and the metallic connector housing; and, forming a protective jacket over the conductive coating between the cable shield and the connector housing.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
146 words
A process for making R. F. shielded cable connector assemblies comprising the steps of: potting the R. F. exposed region of unsupported individual wires, contained in a R. F. shielded cable at the gap formed between the R. F. shielded cable and a connector structure to which the wires are connected, by applying a flexible potting material thereto to fill in, support, partially rigidize and inSulate the individual wires; coating the entire exterior surface of the potting and portions of the adjacent connector housing and R. F. shielding member of the cable with an electrically conductive material to form a totally enveloping adhering electrically conductive path between the R. F. shielding member of the cable and the connector housing; and, forming a supportive, protective jacket over the conductive coating from and including a portion of the cable to and including a portion of the connector housing.
Claim 2
Dependent Claim
146 words
A process for making R. F. shielded cable connector assemblies comprising the steps of: potting the R. F. exposed region of unsupported individual wires, contained in a R. F. shielded cable at the gap formed between the R. F. shielded cable and a connector structure to which the wires are connected, by applying a flexible potting material thereto to fill in, support, partially rigidize and inSulate the individual wires; coating the entire exterior surface of the potting and portions of the adjacent connector housing and R. F. shielding member of the cable with an electrically conductive material to form a totally enveloping adhering electrically conductive path between the R. F. shielding member of the cable and the connector housing; and, forming a supportive, protective jacket over the conductive coating from and including a portion of the cable to and including a portion of the connector housing.
Claim 3
Dependent Claim
33 words
A process for making R. F. shielded cable connector assemblies as claimed in claim 1 wherein the potting material, the electrically conductive material and the protective jacket all include a similar resin base.
Claim 4
Dependent Claim
24 words
A process for making R. F. shielded cable connector assemblies as claimed in claim 2 wherein said electrically conductive material includes particles of silver.
Claim 5
Dependent Claim
23 words
A process for making R. F. shielded cable connector assemblies as claimed in claim 3 wherein said potting material includes a fluorescent dye.
Claim 6
Dependent Claim
25 words
A process for making R. F. shielded cable connector assemblies as claimed in claim 4 wherein said potting material is a thixotropic urethane resin system.
Claim 7
Dependent Claim
97 words
A process for making R. F. shielded cable connector assemblies as claimed in claim 5 wherein the formation of said protective jacket comprises the substeps of: forming a pattern by shaping a wax block to a predetermined contour; casting a resin mold about said wax block; removing said wax block after said resin mold cures; mounting the thusly formed resin mold about the electrical conductive material, the connector housing and the part of the shield of the R. F. shielded cable adjacent to the electrically conductive material; and, injecting a protective jacket material into the mold cavity.
Claim 8
Dependent Claim
40 words
A process for making R. F. shielded cable connector assemblies as claimed in claim 6 comprising the further substeps of: coating the interior surface of the mold cavity with a thin coating of acrylic resin after removing said wax block.
