Patent number: 7670150Abstract: An electrical connector mountable to a circuit board is disclosed. The disclosed connector includes a shell which comprises a first plate-like portion, a second plate-like portion and connection portions. The first plate-like portion extends in a predetermined direction and is provided with fixed portions at opposite ends thereof in the predetermined direction. The fixed portion is to be fixed to the circuit board. The second plate-like portion extends in the predetermined direction. Each of the connection portions connects the first and the second plate-like portion. The second plate-like portion is provided with force resist portions at opposite ends thereof in the predetermined direction. The force resist portions are configured so that, when a force is applied to the electrical connector along a direction from the first plate-like portion towards the second plate-like portion, the force resist portions resist the force.Type: GrantFiled: June 12, 2008Date of Patent: March 2, 2010Assignee: Japan Aviation Electronics Industry, LimitedInventors: Kazuhito Hisamatsu, Masaki Yamashita, Takahiro Yamaji, Tatsuya Shioda

Patent number: 7320623Abstract: In a connector including a fitting portion to be fitted to a mating connector, signal contacts are disposed in the fitting portion in a first row. A ground plate includes a plurality of ground terminals disposed in the fitting portion in a second row parallel to the first row. These contacts are held by a housing. A conductive shell is coupled to the housing and includes a shell body partially covering these contacts, a bent portion bent inward from the shell body at an end of the fitting portion, and a protecting portion extending from the bent portion with a space which is kept between the protecting portion and the shell body. Each of the ground terminals includes a spring portion extending in the fitting portion and a free end portion extending from the spring portion and inserted into the space with being contacted with the protecting portion.Type: GrantFiled: December 6, 2006Date of Patent: January 22, 2008Assignee: Japan Aviation Electronics Industry, LimitedInventors: Kazuhito Hisamatsu, Kazukuni Hisatomi

Patent number: 6890193Abstract: An insulator (40) retains a plurality of conductive signal contacts (10) arrayed in a first direction (A1) for contacting with signal contacts of a counterpart connector, and further retains a conductive ground plate (20). The ground plate is arranged so as to be spaced apart from the signal contacts and has a plurality of ground contacts (24, 25) for contacting with ground contacts of the counterpart connector. These ground contacts are arrayed in the first direction and joined to each other via a joining portion (21). A connection piece (32, 33) extends from a part of the joining portion in the same direction as each of the ground contacts. The connection piece contacts with a conductive shell (60) formed separately from the ground plate and covering the insulator.Type: GrantFiled: September 29, 2003Date of Patent: May 10, 2005Assignee: Japan Aviation Electronics Industry, LimitedInventors: Akira Kimura, Kazuhito Hisamatsu, Masaaki Takaku
