SEMICONDUCTOR PRESSURE SENSOR

摘要

PURPOSE:To improve water resistance without the invasion of water into the sensor by providing the wall for water-proof so as to surround the circumference of the air introducing hole together with the locking part in the projected height direction of the locking part. CONSTITUTION:A wall 19 for water-proof is formed by molding in a single body with a plastic housing 2 at the same height as the locking part 7 so as to surround the circumference of an air introducing hole 4 together with the locking part 7 at the whole circumference of a connector part 5 projected and formed to a plastic housing 2. Consequently, the air introducing hole 4 is opened at one edge surface side by the wall for water-proof, other whole circumference is covered, and therefore, the water pressure is not loaded directly and the invasion of the water in a space 20 from the air introducing hole 4 can be prevented.
