The high-voltage connector assembly according to embodiments disclosed herein may include a cover defining an outer appearance and a shielding plate designed to shield an electrical noise signal. The cover and the shielding plate may be integrally formed by a double shot molding or insert injection molding. Accordingly, manufacturing time and costs of the cover and the shielding plate may be reduced. In addition, the cover and the shielding plate may be coupled to each other in a more stable manner. Further an outer circumferential portion of the shielding plate may have a higher roughness than the cover. Alternatively, the outer circumferential portion of the shielding plate may be provided with a plate protrusion or an uneven portion. Accordingly, a contact area between the shielding plate and the cover may be increased. ## Claims ### Claim 1 A high-voltage connector assembly, comprising: a cover comprising an opening portion formed on a first side of the cover and a space portion communicating with the opening portion;
