CONSTRUCTION OF SEALING THROUGH-HOLE PENETRATING THROUGH METALLIC PARTITIONING MEMBER

Title:

CONSTRUCTION OF SEALING THROUGH-HOLE PENETRATING THROUGH METALLIC PARTITIONING MEMBER

Document Type and Number:

WIPO Patent Application WO/1993/025829

Kind Code:

A1

Abstract:

In a construction wherein a hole (5) is formed in a base member (4) made of metal as being a partition member for gas-tightly or liquid-tightly partitioning regions disposed on opposite sides, and an electric conductor (1), a pipe member, through which gas or liquid is caused to flow, a heat pipe, through which a heat transfer medium is caused to flow, an optical fiber for transmitting optical signals, and the like are passed through the hole (5) to be led out therefrom, each of said members is disposed through a sealing member (3) made of synthetic resin, said hole (5) is sealed by sealing by plasticity deformation action of the base member (4) and the deformation action through the utilization of elastic plasticity of the sealing member (3), whereby high pressure-tight performance is achieved against superhigh pressure, so that said hole (5) can be sealed stably for a long period of time.
