The invention provides a fully automatic terminal crimp connection device free of mold replacement. The fully automatic terminal crimp connection device comprises: an equipment base frame, a cable conveying platform, a mold-replacement-free terminal crimp connection mold, a terminal automatic feeding device and a control device. The mold-replacement-free terminal crimp connection mold is fixedly disposed on a side of the control device. The cable conveying platform and the terminal automatic feeding device are located on both sides of the control device. The cable conveying platform, the replacement-free terminal crimp connection mold, the terminal automatic feeding device and the control device are all fixed on the upper part of the equipment base frame. The replacement-free terminal crimp connection mold and the terminal automatic feeding device are electrically connected with the control device. The control device is provided with an operation button for control and a display screen. The upper part of the cable conveying platform is also provided with a sliding slot and eight cable feeding rollers arranged in two rows. The technical problem to be solved by the present inventionis to provide a terminal crimp connection device simple in structure, high in intellectualization, and capable of automatically crimping terminals of different specifications without replacing the mold.
