An isolated waterproof cable for a wire and an electrical device provided with the same are disclosed. The isolated waterproof cable for a wire includes: a wire body (11) including at least one core wire (110), each core wire includes a conductive wire (113) and an insulating sheath (112) provided outside the conductive wire (113); a seal provided at an end of the wire body (11); and at least one connector (12) connected with the conductive wire (113), and a segment of the connector (12) or the conductive wire (113) is sealed within the seal. The isolated waterproof cable for a wire provided by the embodiments of the present application prevents water vapor from flowing along the conductive wire and entering the electric device by sealing a segment of the connector or the conductive wire, thereby providing good waterproof performance, for example, the camera fogging problem can be well solved.
