In vacuum equipment, sealed electrical connectors play a crucial role in providing a reliable and leak-free
feedthrough for electrical signals and power. These connectors are designed to withstand the extreme
conditions present inside vacuum chambers, such as high temperatures, high vacuum levels, and exposure
to various gases and chemicals.
There are several types of sealed electrical connectors commonly used in vacuum equipment, including:
1. Hermetic connectors: These connectors are designed to provide a completely sealed and leak-free
connection between the vacuum chamber and external electrical equipment. They are typically made
from materials such as stainless steel, ceramic, or glass, and are welded or brazed to ensure a hermetic seal.
2. Feedthrough connectors: These connectors are designed to pass electrical signals or power through
the vacuum chamber walls without compromising the vacuum integrity. They are typically made from
materials such as copper, aluminum, or stainless steel, and are sealed using O-rings, glass seals, or elastomers.
3. High-voltage connectors: These connectors are specifically designed to handle high voltages and currents
in vacuum environments. They are often insulated with materials such as ceramic or epoxy to prevent electrical
arcing and ensure safe operation.
4. Coaxial connectors: These connectors are used for transmitting high-frequency signals in vacuum equipment.
They consist of an inner conductor surrounded by a dielectric material and an outer conductor, which are sealed
to prevent signal loss and interference.
Sealed electrical connectors for feedthrough in vacuum equipment must meet stringent requirements to ensure
reliable operation. Some key considerations when selecting sealed electrical connectors for vacuum applications include:
1. Vacuum compatibility: The connectors must be able to withstand high vacuum levels without outgassing or
leaking, which can compromise the vacuum integrity of the system.
2. Temperature resistance: The connectors must be able to withstand high temperatures inside the vacuum
chamber without degrading or failing.
3. Chemical compatibility: The connectors must be resistant to corrosive gases and chemicals present in the
vacuum environment to prevent degradation and ensure long-term reliability.
4. Electrical performance: The connectors must provide low resistance, low capacitance, and low inductance
to ensure efficient transmission of electrical signals and power.

The vacuum electrode flange is usually composed of the following structures:
1. Contact: used to connect two flanges, usually made of copper or stainless steel.
2. Flange: a flat plate mounted on the contact, between which a vacuum sealing chamber is formed.
3. Bolts: Components for fixing and connecting flanges.
4, insulation gasket: the insulation material installed between the bolt and the flange to ensure the insulation performance of the flange.
5, conductive plug: used for grounding at non-standard connections to ensure the electrical safety of the system.
