  • Patent number: 10566741
    Abstract: A shielded connector includes a dielectric module (20) having an L-shaped terminal fitting (24) attached to a dielectric (21) and an outer conductor (30) that houses the dielectric module (20). The outer conductor (30) has a housing (31) with a first opening (35) at a front, a second opening (36) at a rear of a lower surface, and an insertion port (37) at a rear end communicating with the second opening (36). A lid (43) is continuous with an edge of the insertion port (37) and is displaced from an open position where the insertion port (37) is opened to allow insertion of the dielectric module (20) into the module housing (31) to a closed position where the insertion port (37) is closed. With the lid (43) closed, an outer plate (47) on the lid (43) covers the holding portion (41) on the module housing (31) to prevent accidental release.
