A connector assembly includes a female connector having a pair of female terminals inserted into a housing of which one side is open, and including a male connector having a male terminal inserted between the pair of female terminals to come into contact with the pair of female terminals. one end of a female terminal of the pair of female terminals is fixed to an inner surface of the housing. The other end thereof is disposed to extend by a predetermined length. A displacement of the other end occurs toward the one end due to the configuration of the male connector. A contact defect problem during coupling does not occur and reworking of the connector assembly is facilitated.
