`ABSTRACT
`A cable connector with improved performance and ease of
`use . The connector has staggered ports to reduce crosstalk
`and to prevent incorrect insertion of a plug into a receptacle .
`The plug may be constructed with subassemblies , each of
`which has a lossy central portion . Conductive members
`embedded within an insulative housing of the subassemblies
`may be used to electrically connect ground conductors
`within the subassemblies . Further , the connector may have
`a quick connect locking screw that can be engaged by
`pressing on the screw , but requires rotation of the screw to
`remove . Additionally , a ferrule may be used in making a
`mechanical connection between a cable bundle and a plug
`and making an electrical connection between a braid of the
`cable bundle and a conductive shell of the plug . The ferrule
`may be in multiple pieces for easy attachment while pre
`cluding deformation of the cable , which disrupts electrical
`performance .
