Title: An inner and outer pressure equalization structure for an airtight case
Inventor: HARA KOUICH
IPC: H05K5/06
Filed: 1998-12-09
Abstract: An airtight case (10) includes a case body (20) and a cover (30) covering an opening of the case body (20). A side of the cover (30) or the case body (20) is integrally provided with a diaphragm portion (34) made of a resilient material. When electric and electronic parts installed in the case body (10) are heated causing a pressure difference between the inside and the outside of the airtight case (10), the diaphragm portion (34) is elastically deformed to change the inner volume of the airtight case (10), automatically alleviating the inner/outer pressure difference of the airtight case (10) while maintaining the airtightness of the airtight case (10).
