Abstract

The utility model discloses a plug connector, which comprises an insulating body, a conductive terminal fixed in the insulating body, a metal shell and a shielding shell covered outside the insulating body. The insulating body includes a body part and a tongue plate extending forward from the body part. The metal shell covers the outside of the tongue plate, and the shielding shell covers the outside of the main body. The metal shell is provided with a grounding elastic piece abutting against the shielding shell, and in a free state, the grounding elastic piece extends obliquely outward at a certain angle with the main body. Since the grounding shrapnel extends obliquely outward at a certain angle, after the metal shell and the shielding shell are assembled, the grounding shrapnel will ensure stable contact with the upper shielding shell under the action of outward resilience. Therefore, the problem of poor conduction between the metal shell and the shielding shell will be better improved.
