PURPOSE:To satisfy prescribed performance up to 1GHz band by making a structure of a plug socket for interior finish of a substrate, whereon a distribution circuit is mounted, a prescribed one while enlarging an area of an earth part. CONSTITUTION:A plug socket body 1 has a substrate 30 mounted with a bi- branched circuit such as supplying to FM.TV. The body is so formed that the rear may open and a shield plate 40 is fitted into the opening part for being fixed. The receptacles 20a and 20b are provided in front of the body, and an outside conductor of a connector connected to an outside conductor of a coaxial cable is electrically connected to the outside contact shoes 23, 23 thereof. An earth pattern and a shield plate 40 of the substrate 30, further the shield plate 40 and an outside conductor of the coaxial cable are electrically connected through the contact springs 33a and 33b. Thereby, an area of the earth part is enlarged so that prescribed performance is satisfied up to a 1GHz band. |
