Patent number: 9099810Abstract: A half fitting prevention connector includes a cylindrical case, a connector body, a lever, and a release lever. The release lever has a lock hole. An electromagnetic coil has a plunger. The plunger is arranged so as to face a microswitch. The electromagnetic coil is excited by connection between the signal terminal of the connector body and a signal terminal of a mating connector, and thereby moving the plunger toward the microswitch. The release lever is rotatable so that the plunger can enter the lock hole to press the microswitch in a state that the connector body is completely fitted with the mating connector and the plunger cannot enter the lock hole in a state that the connector body is half fitted with the mating connector.Type: GrantFiled: May 18, 2012Date of Patent: August 4, 2015Assignee: Yazaki CorporationInventor: Takenori Ohmura

Patent number: 9088110Abstract: In an electrical connector, a latch claw is provided at a nearer side than a lock claw in a fitting direction of a connector fitting portion to a power receiving connector. While the latch claw is retracted into the connector fitting portion, the latch arm swings to release the latching between a latch piece and a second latch groove portion. The power feedability determining mechanism includes a movable shaft moving in a direction perpendicular to the fitting direction when a half-fitting state changes to a fitting state, and a regulation arm insertable into or extractable from an air gap of a lock arm according to the movement of the movable shaft. The regulation arm is inserted into the air gap to regulate swinging of the lock arm.Type: GrantFiled: July 7, 2014Date of Patent: July 21, 2015Assignee: YAZAKI CORPORATIONInventor: Takenori Ohmura
