Filed:

May 11, 2004

Appl. No.:

10/843534

Inventors:

Steven R. Cooper - Round Lake Beach IL, US
Zenon Sliczniak - Saint Charles IL, US

Assignee:

Switchcarft, Inc. - Chicago IL

International Classification:

H01R029/00

US Classification:

439188

Abstract:

A switching coaxial jack has an electrically grounded housing that supports first and second connectors at a first end of the housing and third and fourth connectors at a second end of the housing. A first center conductor is disposed within the first connector, a second center conductor is disposed within the second connector, a third center conductor is disposed within the third connector, and a fourth center conductor is disposed within the fourth connector. A sliding switch within the housing has a first position that electrically couples the first and third center conductors to one another and a second position that electrically couples the first center conductor to one of the second center conductor and the terminating element.

Assignee:

Switchcraft, Inc. - Chicago IL

International Classification:

H01R 29/00

US Classification:

439188, 439944

Abstract:

A coaxial jack has an electrically groundable housing including first and second ports, a printed circuit board supporting a terminating element and conductive traces, and a center conductor disposed within the electrically groundable housing. The center conductor extends through a hole in the printed circuit board and is normally coupled to the electrically groundable housing contact through the terminating element and the conductive traces. A grounding spring has a leaf spring that acts as switch to break the coupling when a plug is inserted into the first port.

Inventors:

Steven Cooper - Round Lake Beach IL, US
Zenon Sliczniak - Saint Charles IL, US

International Classification:

H01R 24/04

US Classification:

439668000

Abstract:

A switching coaxial jack has at least first, second, and third coaxial center conductors, a switch, and a cam. The switch has a first position that electrically couples the first and second center conductors to one another and a second position that electrically couples the first and third center conductors to one another. A cam is responsive to a plug inserted into the jack to apply a lateral force against the plug and/or to operate the switch between its first and second positions.
