The shielded electrical connector assembly includes a shield terminal having an attachment portion configured to be connected to a shield conductor of a coaxial cable and a connection portion configured to be received within a mating shield terminal and a contact cage surrounding a forward segment of the connection portion and slideably attached to the shield terminal. The contact cage defines a plurality of arcuate contact arms configured to be in intimate compressive contact with a mating shield terminal inner wall which causes the contact cage to extend rearwardly when the shield terminal is inserted within the mating shield terminal. Methods of forming and interconnecting a shielded electrical connector assembly are also presented herein. ## Claims ### Claim 1 A shielded electrical connector assembly, comprising: a shield terminal having an attachment portion configured to be connected to a shield conductor of a coaxial cable and a connection portion configured to be received within a mating shield terminal;
