The invention relates to a network cable connector composed of a lower shell and an upper shell. The shape of the inner edge of the lower shell is identical to that of the outer edge of the upper shell. The size of the inner edge of the lower shell is slightly larger than that of the outer edge of the upper shell. The lower shell is provided with a through trunking, and an opening of the trunking is located in the outer side of the lower shell. A metal connecting sheet is arranged in the upper shell, and the two ends of the metal connecting sheet are provided with cutting edges and are downward. The network cable connector has the advantages that the cable sequence does not need to be considered during connection of network cables, it is only needed to insert core wires in the same color into the trunking and then buckle the lower shell, and therefore connection of the network cables becomes simple and easy. The network cable connector is simple and small in structure and convenient to carry and use.
