Patent number: 9653848Abstract: A connector includes a housing and a plurality of signal contacts and a plurality of ground contacts. Each contact includes a contact portion that contacts an object, a connection portion mounted on a substrate, and a fixing portion located between the contact portion and the connection portion in the vicinity of the connection portion. The signal contact and the ground contact are aligned and held in the housing, and the fixing portion is fixed to the housing. When the plurality of signal contacts are arranged between the ground contacts, at least two of the ground contacts are coupled and connected integrally or by a separate component, the coupling and connection being made in a section of each ground contact between one end (leading end) of the contact portion and the fixing portion, so that high-frequency transmission characteristics are improved.Type: GrantFiled: January 25, 2016Date of Patent: May 16, 2017Assignee: DDK Ltd.Inventors: Tadashi Masubuchi, Takuya Higeta, Masayoshi Nemoto
