Publication number: 20230135482Abstract: An electrical connector is attached to a wiring substrate and mated with a counterpart connector connected to a signal transmission medium. A shell of the electrical connector has a pair of wall parts that contact a ground member on the counterpart connector. One wall part distant from the signal transmission medium includes a first side plate that has one end attached to a ground conductive path of the wiring substrate and extends in a direction away from the wiring substrate, a joining part that has one end joined to another end of the first side plate, and a second side plate that has one end joined to another end of the joining part and extends in a direction closer to the wiring substrate. The second side plate has a contact piece that extends in a direction away from the wiring substrate and elastically contacts the ground member.Type: ApplicationFiled: December 27, 2022Publication date: May 4, 2023Applicant: DAI-ICHI SEIKO CO., LTD.Inventor: Takashi MASUNAGA

Publication number: 20230006378Abstract: An electrical connector pair 1 includes a receptacle connector 1a and a plug connector 1b. The receptacle connector 1a includes a first partition wall 12a, and the plug connector 1b includes a second partition wall 12b. When the receptacle connector 1a and the plug connector 1b are fitted together, the first partition wall 12a partitions a portion of the boundary between a third holder and a fourth holder where the second partition wall 12b is not formed such that a first contact 10a and a third contact 10b cannot be seen from a second contact and a fourth contact.Type: ApplicationFiled: December 1, 2020Publication date: January 5, 2023Applicant: I-PEX Inc.Inventors: Yuki MIYAZAKI, Tadamichi YAYOSHI, Takashi MASUNAGA
