What are the fundamentals, knowledge, concepts, and specifications for gas-tight connector design?

A gas-tight connector is a connector designed to achieve gas-tightness in high-pressure, low-pressure or vacuum environments. It utilizes special sealing structures and materials at the connector interface to ensure that the connector effectively prevents gas leakage and the entry of outside gases. The following are some of the key points of the gas seal connector design basics, knowledge, concepts and specifications: sealing structure design basics: O-ring seal: common gas seal connectors use O-ring seals, by compression of the O-ring in the connector interface to form a seal. Metal Seals: Certain high pressure or vacuum environments use metal sealing rings to achieve a gas seal. Insulation sealing: In addition to air sealing, connectors also need to have electrical insulation to prevent electrical leakage. Sealing material selection: sealing materials must have good sealing performance, pressure resistance and corrosion resistance, common materials include silicone, fluorine rubber, fluorine plastic, polytetrafluoroethylene (PTFE) and so on. The selection of sealing materials need to consider the temperature, pressure and medium of the working environment and other factors. Connector design features: the connector shell and interface must have sufficient strength and rigidity to withstand the pressure and force of the connection process. The contact part of the connector should have good electrical conductivity and corrosion resistance to ensure a stable electrical connection. Philosophy and Objective: The design philosophy of gas-tight connectors is to ensure the reliability and stability of the connector in harsh environments to prevent gas leakage or entry of outside gases, thereby protecting the performance and life of the equipment. The goal is to achieve a high quality seal that ensures the reliability of the connector over long periods of operation and under harsh conditions. Codes and Standards: Gas-tight connector designs need to follow relevant codes and standards, such as those of the International Organization for Standardization (ISO), military standards (MIL-STD), and industry standards to ensure that the connector is compliant and meets the needs of the specific application.
