Patent number: 11769970Abstract: A connector includes an outer shield, a terminal surrounded by the outer shield, a housing fixed to the outer shield and holding the terminal; and an inner shield surrounded by the outer shield. The outer shield, the inner shield, and two virtual paths that connect the two tip regions of the inner shield to the outer shield by shortest distances, respectively, constitute plural electrically-closed loops surrounding the terminal. The electrically-closed loops include one or more particular electrically-closed loops. Each of the one or more particular electrically-closed loops does not surround any electrically-closed loop among the plurality of electrically-closed loops other than the each of the one or more particular electrically-closed loops. A longest loop length of the one or more loop lengths of the one or more particular electrically-closed loops is shorter than a wavelength of a maximum frequency of a transmission signal flowing through the terminal.Type: GrantFiled: July 8, 2022Date of Patent: September 26, 2023Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Ryosuke Shimomura, Yoji Miyazaki, Hiroshi Tanaka, Kazumasa Iijima
