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.

Dependent claims

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;
a shielding plate disposed inside the cover and integrally formed with the cover, the shielding plate being configured to cover the opening portion and to shield noise generated in an Electromagnetic Compatibility (EMC) filter;
a support plate located adjacent to the cover and configured to support a high-voltage cable inserted into the cover;
a sealing part located adjacent to the support plate and configured to surround the inserted high-voltage cable;
and
a holder coupled to the cover to hermetically seal an inside of the cover, the holder being detachably coupled to a second side of the cover,
wherein:
the second side of the cover is provided with a boss portion protruding by a first predetermined distance;
the boss portion comprises a cable insertion portion communicating with the space portion and configured to be opened so as to allow the high-voltage cable to be inserted;
the holder is coupled to the cover to cover the cable insertion portion;
the boss portion includes a holder coupling protrusion that protrudes from an outer surface of the boss portion by a second predetermined distance;
the holder comprises:
a cover coupling portion protruding in a lengthwise direction by a third predetermined distance;
and
a cover insertion hole formed though the cover coupling portion at a predetermined angle with respect to the lengthwise direction of the cover coupling portion;
and
the holder coupling protrusion is inserted into the cover insertion hole in manner of snap-fit when the holder is coupled to the cover.
