A connector, a connector assembly and an assembling method thereof

摘要

An object of the present invention is to suppress the abrasion of terminal fittings due to vibration. A female connector F is provided with an outer housing 10 in the form of a bottomed tube, a spring member 50 to be accommodated in the outer housing 10, and an inner housing 30 to be accommodated in the outer housing 10 to sandwich the spring member 50 between the inner housing 30 and a back wall 12 of the outer housing 10 and adapted to hold female terminal fittings 80. The inner housing 30 is pushed by a male connector M to move toward the back wall 12 and is floating-supported between the back wall 12 and the male connector M via the spring member 50 to move in connecting directions when the male connector M is fitted into the outer housing 10 to be locked therein. Upon an occurrence of vibration, the inner housing 30 is capable of moving while following movements of the outer housing 10.
