Abstract
An improved electro/mechanical connector through which multi-media electrical signals are transported includes a first port with resilient contact tongues, a second port for supporting a coaxial assembly and a third port coupled to a circuit module which receives the multi-media electrical signals on an input terminal splits the multi-media electrical signals into broadband signals which are routed to the coaxial assembly and baseband signals which are routed to the first port. The circuit module also receives broadband signals and baseband signals from the coaxial assembly and first port respectively combines them into the multi-media signals which are outputted on the input terminal.
