Abstract: A high-voltage connector assembly and a motor-operated compressor including the same are disclosed. 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.

Abstract: A scroll compressor is provided in which a center of a back pressure chamber is eccentrically disposed relative to a center of a fixed scroll. For example, the center of the back pressure chamber may be moved towards a center of an orbiting scroll at a time of discharge, thereby preventing displacement of the fixed scroll and ensuring stability in orbital movement of the orbiting scroll.
