The present disclosure provides a connector assembly. The connector assembly includes a wire-end connector. The wire-end connector includes a wafer, a shield plate and a twin-ax cable. The wafer includes a frame and a terminal group. The terminal group is supported by the frame. The terminal group includes a signal terminal pair and a ground plate. The ground plate includes a ground terminal on both sides of the signal terminal pair. The shield plate is electrically connected to the ground plate. The shield plate includes an opening that penetrates the shield plate. The twin-ax cable includes a pair of conductors and a ground portion. The pair of conductors extend into the opening of the shield plate and are electrically connected to the signal terminal pair. The ground portion electrically connects at least one of the shield plate and the ground plate.

A connector includes a connector housing and a shield shell. A terminal electrically connected to an end part of a wire is arranged inside the connector housing. The connector housing includes an inserting portion to be inserted into a mounting hole provided in a conductive case for accommodating an inverter and an outer arrangement portion integral with the inserting portion and to be arranged outside the case. A case-side sealing member seals between the outer peripheral surface of the inserting portion and the inner peripheral surface of the mounting hole. The shield shell is electrically connected to the case and covers the outer periphery of the outer arrangement portion. The inserting portion includes a first intrusion suppressing groove continuously provided over the entire periphery of the inserting portion in a part of the outer peripheral surface of the inserting portion between the case-side sealing member and the outer arrangement portion.
