Patent number: 10622763Abstract: Provided is a connector having reduced height and area that facilitates the retention and removal of a connection object while preventing damages to itself during operation. According to the present disclosure, a connector (10) includes an insulator (20) having an accommodation section (22) for allowing insertion of a connection object (an FPC 60), an actuator (40) attached to the insulator (20), and a locking member (50) that supports the connection object (the FPC 60) accommodated in the accommodation section (22) in an insertion-removal direction. When the actuator (40) is pushed in along a direction substantially orthogonal to the insertion-removal direction, the locking member (50) is elastically deformed and releases the connection object (the FPC 60).Type: GrantFiled: June 22, 2017Date of Patent: April 14, 2020Assignee: KYOCERA CorporationInventors: Nobuyuki Nakajima, Yuusuke Shiroyama, Fumihito Ikegami

Patent number: 10594084Abstract: A connector that, when changing an actuator from an open state to a closed state provides a sound that indicates the actuator has changed to a fully closed state. In one embodiment, the actuator has an open surface, a closed surface, a sloped connection surface, and a tip load transmission portion. The open surface enables insertion of a connection object into an insertion portion in an open state. The closed surface is approximately parallel to the connection object in a closed state. The sloped connection surface connects the open surface and the closed surface. The tip load transmission portion is located at an intersection of the closed surface and the sloped connection surface, and elastically contacts the connection object at a time at which a pressing load imparted by an elastic pressing portion is at a peak.Type: GrantFiled: November 18, 2016Date of Patent: March 17, 2020Assignee: KYOCERA CORPORATIONInventors: Fumihito Ikegami, Masafumi Seki, Ryoichi Manabe
