Connector and the connector assembly

PROBLEM TO BE SOLVED: To provide a connector equipped with a structure preventing rattling while suppressing fitting force.SOLUTION: A connector assembly has a first connector 1 and a second connector 2. The first connector 1 is equipped with a spring member 60 pressed in a housing thereof (an inner housing 70). On the other hand, the second connector 2 has a groove 203 in the housing 201. When fitting, the spring member 60 is inserted in the groove 203 in a fitting direction, and is elastically deformed in a direction intersecting the fitting direction. The housing (the inner housing 70) of the first connector 1 and the housing 201 of the second connector 2 suppress rattling therebetween, through the spring member 60.SELECTED DRAWING: Figure 11
