Patent number: 9583846Abstract: A method of connecting a cable with a cable connector comprises the steps of mounting a signal transmitting contact on a housing of a cable connector, said signal transmitting contact being formed to have an intersecting portion, an inclined portion and mutually opposite crooked portions forming a slit, forming an annular groove on an insulator covering a core wire in a cable, engaging the annular groove on the cable with the crooked portions so that the core wire appearing in the annular groove is pressed into the slit, and causing a part of the insulator of the cable positioned to demarcate the annular groove to be pushed by the inclined portion of the signal transmitting contact to move for projecting from a top end of the cable toward the outside so that the core wire appearing in the annular groove is put in press-contact with the slit.Type: GrantFiled: April 24, 2014Date of Patent: February 28, 2017Assignee: DAI-ICHI SEIKO CO., LTD.Inventor: Junji Ohsaka

Patent number: 9011163Abstract: An annular contact is enabled to be firmly retained by an insulating housing without affecting the mating force or removing force between there and a matching connector with a simple configuration. Divided end parts of the annular contact attached to the insulating housing are provided with contact retaining parts that abut part of the insulating housing and retain the annular contact at the insulating housing when removal with respect to the matching connector is carried out, so that the shapes and sizes of the contact retaining parts are not affected by elastic force of the annular contact, in other words, mating force or removing force with respect to the matching connector almost at all to facilitate adjustment of the mating force or removing force between there and the matching connector.Type: GrantFiled: April 3, 2013Date of Patent: April 21, 2015Assignee: Dai-Ichi Seiko Co., Ltd.Inventor: Junji Ohsaka

Patent number: 8944827Abstract: A guiding function of an annular contact upon mating/removal with/from an opposing connector can be maintained well with a simple configuration. An annular contact is formed with an unruptured annular member having no ruptured part in a circumferential direction and continued in the circumferential direction. As a result, compared with a conventional annular contact having ruptured parts in the circumferential direction, rigidity is increased while maintaining necessary elasticity; and, for example even when an opposing connector is mated or removed in a direction inclined in an axial direction with respect to the axial direction of the annular shape, conventional twisting deformation is suppressed in the annular contact, and the opposing connector is stably guided along the axial direction of the annular shape, thereby well maintaining a mating guiding function of the annular contact.Type: GrantFiled: February 11, 2013Date of Patent: February 3, 2015Assignee: Dai-Ichi Seiko Co., Ltd.Inventor: Junji Ohsaka

Patent number: 8602812Abstract: It is made possible with a simple configuration to electromagnetically shield connection leg portions disposed below a signal transmission medium immediately when both connectors are fitted to each other. A connector main body portion are preliminarily provided with a terminal portion of the signal transmission medium and a transmission-medium-side shield cover that extends from between the another connector (second connector) and the connection leg portions on a transmission-medium side, and the connection leg portions on the transmission-medium side disposed below the signal transmission medium (thin coaxial cables) is covered from above with the transmission-medium-side shield cover when both the connectors are fitted to each other, so that electromagnetic interference (EMI) is successfully prevented from occurring.Type: GrantFiled: September 23, 2011Date of Patent: December 10, 2013Assignee: Dai-Ichi Seiko Co., Ltd.Inventor: Junji Ohsaka
