Patent number: 9698537Abstract: A mating connector, that includes a mating ground portion, includes a holding member, a contact, a shell and a ground member. The holding member is formed of an insulating body defining a connection space, the contact has a contact point which is held by the holding member to be positioned in the connection space, the shell covers, at least in part, the holding member in a plane perpendicular to a front-rear direction, and the ground member is electrically connected with the shell and has a base portion positioned between the holding member and the shell. A ground spring extends from the base portion and a ground contact point to be connected to the mating ground portion, and has first, second and third springs. The third spring is inward of the second spring, and supports the ground contact point to project into the connection space.Type: GrantFiled: May 18, 2015Date of Patent: July 4, 2017Assignee: JAPAN AVIATION ELECTRONICS INDUSTRY, LIMITEDInventors: Yohei Yokoyama, Masaaki Takaku, Kouhei Ueda, Tatsuya Shioda, Yoshio Minegishi
