A modular plug includes a modular plug body and a metal shielding cover. The modular plug body has an inner chamber. The modular plug body has a first end and an opposite side end. Metal terminals are disposed at the first end. The second end defines an opening in communication with the inner chamber. The opening is configured to allow a cable to be inserted through the opening into the inner chamber. The metal shielding cover is attached around the modular plug body. The modular plug body defines a first aperture in communication with the inner chamber, and the metal shielding cover includes at least one metal spring tab capable of bending and deforming into the first aperture. The modular plug has a simple structure and ingenious design, which can easily achieve the grounding results, has a reduced cost, and is easy to promote its application.
