Abstract
A cable connector backshell assembly for high frequency applications requiring reduced electromagnetic emissions. Aspects include providing sufficient physical spacing and electrical isolation between the signal conductors and the housing to meet EMI standards for HIPPI-6400 connector assemblies. One embodiment includes spring preloading of the electrical connector. One embodiment includes a longitudinally floating connector.
Claims21
A method of manufacturing a connector, the method comprising:
- providing a conductive housing, the housing having a nose and a terminating end and further including an interior;
- providing an electrical connector, the connector having a plurality of conductive members and encased in a conductive jacket;
- providing an insulative jacket surrounding the conductive jacket of the electrical connector, the insulative jacket rigidly secured to the electrical connector;
- engaging the electrical connector with a linear way of the interior, the linear way disposed along an axis between the nose and the terminating end;
- applying a mechanical force to urge movement of the electrical connector in a direction towards the nose;
- and
- providing a mechanical fastener to enable coupling the housing to a matching connector.
4 more elements
A method comprising:
- encasing an electrical connector with an insulative sleeve;
- engaging the insulated electrical connector with a linear way disposed in an interior of a conductive housing;
- applying a force to urge the electrical connector towards a first end of the linear way;
- and
- providing a clamping assembly to mechanically urge the conductive housing in a direction aligned with the linear way.
2 more elements
A method comprising:
- applying a force to urge an electrical connector in a forward direction relative to a conductive housing, the electrical connector carried substantially internal to the conductive housing and the electrical connector adapted for independent movement relative to the conductive housing;
- engaging the electrical connecter with a matching connector;
- and
- clamping a mating surface of the conductive housing to an electrical circuit housing associated with the matching connector.
1 more element
A method comprising:
- providing an insulative sleeve and an electrical connector, the insulative sleeve disposed around the electrical connector;
- providing a conductive housing having an interior and a mating surface, the interior adapted to accept the insulative sleeve and the electrical connector and allow movement of the insulative sleeve and the electrical connector relative to the conductive housing;
- and
- positioning a spring to urge the insulative sleeve and the electrical connector in a direction towards the mating surface.
