Provided is an apparatus for testing waterproofness of a half-finished product, wherein the apparatus is configured to form a chamber space such that areas of holes and parts of the half-finished product are separated from each other, and high-pressure air is injected into the chamber space, thereby performing a waterproofness test. In addition, a sliding block is provided such that a hole blocking means blocking the holes of the half-finished product is moved forward and backward through engagement and disengagement of a body and a cover without requiring a separate power, and the apparatus includes the body, the cover, a sealing means, and a hole blocking means including a sliding block moved in a lateral direction of the half-finished product, a blocking member blocking a side hole of the holes, and a pushing member pushing the sliding block to be moved forward when the body and the cover are combined.

Apparatus for testing waterproofness of half-finished product

Provided is an apparatus for testing the water resistance of a mobile terminal, by which whether a mobile terminal is water-resistant is checked. Specifically, the apparatus uses a reference chamber unit in order to check the effect of external environmental factors, such as temperature, humidity and the like, in different places and times, in advance, and incorporates the effect of external environmental factors in a mobile terminal water resistance test in a test chamber unit, whereby a more precise test may be performed. The apparatus for testing the water resistance of a mobile terminal using a reference chamber unit is configured to include an air-supply means, a pressure regulator chamber unit, a test chamber unit, a reference chamber unit, a pressure-measuring instrument, and a controller.
