Abstract
Abstract A transition connector for interconnecting a standard coaxial cable to a microcoaxial cable employing a uniquely configured printed circuit module to preserve the integrity of signal transmission by providing controlled impedance paths between the desired cable termination points. The connectors or wire wrap posts to accept the cables are placed upon the module substrate which in turn is mounted in a protected floor-mounted pedestal. By the use of appropriate jumpers, the transition connector can be used as a splice for either the microcoaxial or standard coaxial cables.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
171 words
A transition connector for joining two different coaxial cables, each having a signal conductor and a ground conductor comprising: a substrate; at least one first connector means mounted upon said substrate for receipt of a first coaxial cable and having signal and ground contacts; at least one second connector means mounted upon said substrate for receipt of a second coaxial cable and having signal and ground contacts; and trace means upon said substrate coupled to said first connector means and said second connector means for interconnecting said first and second coaxial cables and matching the characteristic impedances thereof, said trace means including a signal trace connecting said signal contacts of said first and second connector means and disposed on one side of said substrate, a first ground trace disposed on the side of said substrate opposite said one side and in trace-aligned registry with said signal trace, and a second ground trace electrically connected to said first ground trace and connecting said ground contacts of said first and second connector means.
Claim 2
Dependent Claim
171 words
A transition connector for joining two different coaxial cables, each having a signal conductor and a ground conductor comprising: a substrate; at least one first connector means mounted upon said substrate for receipt of a first coaxial cable and having signal and ground contacts; at least one second connector means mounted upon said substrate for receipt of a second coaxial cable and having signal and ground contacts; and trace means upon said substrate coupled to said first connector means and said second connector means for interconnecting said first and second coaxial cables and matching the characteristic impedances thereof, said trace means including a signal trace connecting said signal contacts of said first and second connector means and disposed on one side of said substrate, a first ground trace disposed on the side of said substrate opposite said one side and in trace-aligned registry with said signal trace, and a second ground trace electrically connected to said first ground trace and connecting said ground contacts of said first and second connector means.
Claim 3
Dependent Claim
