US Patent 10283891 Shield terminal

A shield terminal (12) includes a dielectric (22) made of synthetic resin and formed with conductor accommodation chambers (39) inside, inner conductors (15) accommodated in the conductor accommodation chambers (39), an outer conductor (14) for surrounding the dielectric (22), and wall portions (24, 35) constituting the conductor accommodation chambers (39) and formed with air chambers (42, 43, 45 and 46). Focusing on the fact that air has a lower dielectric constant than synthetic resin, the air chambers (42, 43, 45 and 46) are formed in the wall portions (24, 35) constituting the conductor accommodation chambers (39). This enables an impedance to be enhanced even if the dielectric (22) is made of a material having high rigidity.
