Patent number: 7021966Abstract: A right angle coaxial connector is fitted into a corresponding connector in a fitting direction substantially perpendicular to a direction that a connecting cable extends. The right angle coaxial connector includes an outer conductor having a cylindrical portion with an axial line in the fitting direction and a lid portion covering an inner space of the cylindrical portion and extending over a covering portion of the connecting cable. The lid portion is integrated with the cylindrical portion at a part of a periphery of the cylindrical portion through a bent connecting portion. The lid portion includes a holding portion at an extending end thereof for pressingly holding the connecting cable. The cylindrical portion includes engaging portions for engaging the corresponding connector. One of the engaging portions located at a position where the cable extends has an engaging amount larger than that of the other engaging portions at other positions.Type: GrantFiled: July 22, 2004Date of Patent: April 4, 2006Assignee: Hirose Electric Co., Ltd.Inventors: Kazuhiko Ikeda, Naoyuki Asano
