Appliance air conditioner compressor terminal block

The glass‑sintered terminal post for air‑conditioner compressors is a critical electrical sealing component in refrigeration and HVAC systems. Leveraging glass‑sintering encapsulation technology, it ensures reliable hermetic insulation between the metal leads and the housing, effectively isolating the compressor’s internal refrigerant and lubricating oil to prevent media leakage and electrical tracking or short circuits.

Semi-hermetic compressor terminal block

The glass-sintered terminal board for semi‑hermetic compressors is the core electrical sealing component of such compressors. Utilizing a glass‑sintering encapsulation process, it achieves an integrated, hermetically sealed, and electrically insulating assembly between metal conductive leads and a metal substrate, replacing conventional rubber or plastic sealing structures.

Sensor connector

The sensor connector employs a glass‑sintering encapsulation process, serving as an electrically and hermetically sealed transition component that ensures signal conduction while providing isolation between the external circuitry and the internal sensing chamber. The product integrates metal pins with the substrate through glass‑melting sintering, offering both reliable electrical insulation and superior hermetic sealing. It effectively prevents moisture, corrosive media, and high‑pressure fluids from entering the sensor cavity, thereby protecting the internal sensitive sensing chip from environmental degradation.

Various types of sight glasses

The sight glass employs a glass‑sintering sealing process and serves as a hermetically sealed viewing window in industrial equipment, enabling observation of internal operating conditions. By sintering glass to a metal substrate at high temperatures, it achieves a high‑strength, gas‑tight seal, simultaneously providing both optical transparency for observation and pressure‑resistant sealing. It is widely used in refrigeration compressors, pressure vessels, hydraulic tanks, and industrial fluid‑handling equipment.

Custom multi-core aviation connector

Custom multi‑core aviation connectors, based on a glass‑sintering encapsulation process, are highly reliable hermetically sealed electrical connectors. They can be tailored to meet specific requirements for pin count, pin layout, and mounting specifications, enabling the conduction of multiple signal and power circuits while providing hermetic isolation of the cavity.

Through high-temperature fusion sintering of glass and metal, the leads and housing form an integrated hermetic seal, offering excellent electrical insulation and superior gas tightness to prevent the ingress of moisture, oil, and corrosive media into the device. The product is resistant to vibration and shock, withstands a wide range of operating temperatures, and can operate reliably under demanding conditions such as vacuum and high pressure.
