Surface mount type receptacle of coaxial connector and mounting arrangement for mounting receptacle of coaxial connector on substrate

摘要

A surface mount type receptacle of a coaxial connector is provided which is mounted on a substrate having a hot-line pattern conductor and a top earth pattern conductor formed on a top surface thereof, and a bottom earth pattern conductor formed on a bottom surface thereof. A dielectric case of the receptacle has a concavity formed to extend from the top surface thereof toward the center thereof. In the concavity, inner and outer conductors are arranged. At least one hot-line terminal is formed in the case to be electrically connected to the inner conductor and extend from the inner conductor through the side surface of the case to the bottom surface thereof, and an earth terminal is formed in the case to be electrically connected to the outer conductor and extend from the outer conductor to the bottom surface thereof, the earth terminal having a main portion thereof provided in the case to oppose to the bottom surface of the case. The earth terminal is formed between the main portion of the hot-line terminal and the top surface of the substrate to decrease an area where the hot-line terminal opposes to the bottom earth pattern conductor when the receptacle is mounted on the top surface of the substrate. Further, the top earth pattern conductor is formed between the main portion of the hot-line terminal and the top surface of the substrate.
