Patent number: 9583854Abstract: To provide a connector wherein ground terminals can be designed easily, which not only suppresses the occurrence of impedance mismatch and crosstalk, but which does not lead to interferences between contacting portions. A ground terminal for a connector has a cylindrical main body. A plurality of contacting portions, for contacting a circuit board, are formed on the bottom edge of the cylindrical main body. The ground terminal has, as contacting portions, inner contacting portions and outer contacting portions. The inner contacting portions extend toward the inside of the cylindrical main body and in the downward direction, and the outer contacting portions extend toward the inside of the cylindrical main body and in the downward direction.Type: GrantFiled: May 11, 2011Date of Patent: February 28, 2017Assignees: Molex Japan Co., Ltd., Advantest CorporationInventors: Ryo Uesaka, Jun Watanabe, Akinori Mizumura, Hirotaka Wagata

Patent number: 8690583Abstract: A probe connector (1) connects a circuit board (2) and a coaxial plug (3) including an axial terminal (162) and a surrounding terminal (163). A coaxial probe (51) of the probe connector includes a center terminal (52) connected to the circuit board and the axial terminal; and an outer terminal (61) coaxial with the center terminal and connected to the circuit board and the surrounding terminal. The outer terminal includes an cylindrical outer conductor (62) surrounding the center terminal and mated with the surrounding terminal; an anchor (63) formed, as a projection (69), on part of an outer surface of the outer conductor by machining process so that a hole is formed on the part of the outer surface; and a conductive cover (91) covering and closing the hole and electrically conducted to the outer conductor. Thus, the position of the coaxial probe is slightly shifted even when the coaxial plug is inserted thereto or pulled therefrom.Type: GrantFiled: October 12, 2009Date of Patent: April 8, 2014Assignee: Molex IncorporatedInventors: Ryo Uesaka, Akinori Mizumura, James Maroney
