1. A plug connector, comprising:
a housing;
a built-in circuit board, the built-in circuit board being partially located in the housing, the built-in circuit board comprising a tongue plate and a plurality of conductive pads provided on the tongue plate; and
a cable, the cable being electrically connected to the built-in circuit board;
wherein the plug connector further comprises two locking arms installed in the housing, a driver mated with the locking arms, and a pull strap connected with the driver;
wherein each locking arm comprises a locking protrusion at a first end of the locking arm, an abutting portion located at a second end of the locking arm, and a pivot portion located between the locking protrusion and the abutting portion, the locking protrusion protrudes beyond the housing along a thickness direction of the plug connector;
wherein the driver comprises two driving arms, each driving arm matches with a corresponding locking arm, each driving arm comprises a protruding portion for pulling the abutting portion;
wherein the locking arm is rotatable around the pivot portion when the pull strap is pulled by an external force, so that the locking protrusion moves along the thickness direction inside the housing;
wherein the plug connector further comprises two return springs, each return spring abuts against a corresponding locking arm, and each return spring is adapted to return the corresponding locking arm to an original position after the external force is removed; and
wherein each locking arm comprises a first recess and a mounting post disposed opposite to the first recess along the thickness direction of the plug connector; both the first recess and the mounting post are disposed on a first side of the pivot portion along a mating direction of the plug connector; the locking protrusion is disposed on a second side of the pivot portion along the mating direction of the plug connector; the first side and the second side are disposed oppositely with respect to the pivot portion along the mating direction of the plug connector; the protruding portion of the driving arm is received in the first recess; one end of the return spring is sleeved on the mounting post and another end of the return spring abuts against the housing.
