Patent ID: 8303343

Claim:
A multipolar plug in which a tubular shell that is a cover for a circumference of a fitting portion for a counter connector is formed by applying a bending process on a metal plate, thereby providing said shell with a shielding property, and said shell has a seam joint, wherein said seam joint is disposed in a position which is biased to one side of a center line of said shell, a plurality of contacts which are attached to a body made of an insulating material, said plurality of contacts being surrounded by said shell and including a plurality of contact pairs for transmitting high-speed differential signals, all of said plurality of contact pairs being disposed in a contact pair region of said shell, said shell including a non-contact pair region that is disposed adjacent to said contact pair region, and wherein said seam joint is disposed at a location within said non-contact pair region and spaced from said contact pair region so that leakage of high frequency noise produced by the plurality of contact pairs via a qap in said seam joint is reduced.
