Patent number: 7544067Abstract: A board mount-type connector having an insulative housing with a base and a row of contacts carried by the housing is disclosed. Each contact has a centerpiece secured to the housing along a substantially vertically upright inner wall of the base, a mating interface connected to one end of the centerpiece so that the mating interface contacts a mating contact, and a board interface connected to the remaining end of the centerpiece so that the board interface connects to a circuit board. Each board interface has a bend that initially extends away from an extension line associated with a generally vertically upright portion of the respective centerpiece and that is bent back toward the extension line. A pad interface extends from the free end of the board interface toward the extension line and the contacts of the row are staggered along a length of the row.Type: GrantFiled: February 29, 2008Date of Patent: June 9, 2009Assignees: Tyco Electronics AMP K.K., Advantest CorporationInventors: Takahiro Hatano, Makiya Kimura, Tomoyuki Takamoto, Shin Sakiyama, Takashi Sekizuka

Publication number: 20070004254Abstract: A connector mounted on a board having a plurality of board signal lines for transmitting a signal and a board ground line grounded. Each of the plurality of board signal lines includes a plurality of signal terminals formed in correspondence to each of the signal lines. Each of the signal terminals comprises: a signal core line formed of conductor by extension in the shape of a line; a shield for core line formed of conductor insulated from the signal core line electrically so as to extend in an axis direction of the signal core line and enclose the signal core line; a signal electrode formed by extension from the signal core line for connecting the signal core line with the board signal line corresponding to the signal terminal; and a plurality of ground electrodes extended from the shield for core line and opposed to each other by intervention of the signal electrode for connecting the shield for core line with the board ground line respectively.Type: ApplicationFiled: September 5, 2006Publication date: January 4, 2007Applicant: Advantest CorporationInventors: Shigeru Murayama, Masanori Kaneko, Shigeru Matsumura, Takashi Sekizuka, Hiroyuki Hama
