Patent number: 9209561Abstract: A connector structure includes a first connector and a second connector. The first connector includes a first connector housing and an engagement arm that can be elastically bent. The second connector includes a second connector housing, a slider provided on the second connector housing, a biasing portion that biases the second connector housing in a connector decoupling direction, and an arm engagement portion engaged with the engagement arm. During a coupling process of the first and second connectors, the slider is slid by a pressing force applied from the first connector against a biasing force generated by the biasing portion. The biasing portion includes an elastically-bendable arm provided on the slider, and a tapered surface provided on the second connector housing. The biasing force is generated as a reaction force of an elastically-restorative force of the elastically-bendable arm bent by the tapered surface.Type: GrantFiled: October 21, 2014Date of Patent: December 8, 2015Assignee: YAZAKI CORPORATIONInventors: Tomoyuki Miyakawa, Kazuto Ohtaka, Hideki Honma
