The airtight sealing technology of vacuum connectors can prevent any type of material from leaking out of the container. Many industries use sealed connectors for insulation and conductivity through vacuum feedthrough, and can withstand high voltage and harsh environments. Sealed connectors are used in aerospace, pharmaceutical, and military applications.

1. Glass to glass seals for connectors:

These sealed terminal seals fix the glass components together. Glass to glass seals used for connectors are an ideal choice for manufacturing multi-layer glass windows and glass tubes. Due to the large gap in thermal expansion coefficient, these seals require at least five layers of glass. Make compatibility difficult.

2. Glass metal seals for connectors:

Sealed terminal seals can be used to fuse glass components onto metal surfaces, and the glass to metal seals of connectors act as conductors to protect mechanical devices from the effects of dust and microbial growth. Glass becomes the insulator between the sealed connector pins and the metal package, and the most common application of this terminal seal is in light bulbs.

3. Ceramic metal seals for connectors:

Ceramic metal seals are assembled by passing them through a furnace and applying metal design. This type of sealed connector and seal may be a bit expensive, but it is more resistant to high-pressure environments. These seals are typically used in high-pressure environments such as automotive, medical, and aerospace.

4. Ceramic glass seals for connectors:

This type of seal is very suitable for environments that are considered high stress, high temperature, and high pressure, and the ceramic to glass seal of the connector can seal 3000 volts of electrostatic sparks. Although ceramic to glass seals used for connectors are the most expensive, they can replace glass and ideal applications include motors and signal transmission equipment.

5. Epoxy resin sealing of connectors:

Some epoxy resins can be used to form vacuum seals in materials such as copper or brass, and the design flexibility of epoxy resin seals for connectors makes them an ideal choice for coaxial cable sealing. However, applications are limited as they can only withstand small temperature changes.
