A receptacle connector includes a housing having a first sidewall and a second sidewall. An inserting hole is defined in a middle position of the first sidewall. A first slot and a second slot are defined in the second sidewall. A first conductive terminal has a first contact arm. The first conductive terminal inserts into the housing along the first slot. The first contact arm extends to the inserting hole. The second conductive terminal has a second contact arm. The second fixing arm and a second bending arm connect the second contact arm to the second fixing arm. The second conductive terminal inserts into the housing along the second slot. The second conductive terminal inserts into the housing along the second slot.
