A cable connector assembly includes a housing and a plurality of conductive contacts located in the housing. The housing defines a receiving room therein and a mating port through which a complementary connector is inserted into the receiving room. A plurality of cables electrically connects with the conductive contacts. A latch mechanism is assembled to an outside face of the housing and includes a latch member and a pulling member connecting with the latch member. The latch member defines a pair of hook portions inserted into the receiving room from the outside face and latching with the complementary connector. The latch member further defines a pair of shaft pins and the pulling member defines a pair of shaft holes. The shaft pins are pivotedly received in the shaft holes.
