Overmolded ECU device

摘要

A sealing device which is used to seal a leak test aperture in an ECU. The sealing device is selectively disposed in the leak test aperture, and an inner surface is formed as part of the leak test aperture. The sealing device has a first portion, and a second portion connected to the first portion. The sealing device is press-fitted into the leak aperture such that the first portion is in contact with the inner surface, securing the position of the sealing device in the leak test aperture, and the second portion is also in contact with the inner surface to prevent moisture and debris from passing through the leak test aperture. The second diameter is larger than the first diameter such that the second diameter of the second portion applies a pressure to the inner surface of the leak test aperture, forming a seal.
