Refined R&D of connector‑compatible accessories to strengthen the reliability baseline of the entire connection assembly.
A complete and reliable connector system, in addition to the connector body itself, relies on complementary components such as sealing O-rings, locking latches, insulating washers, positioning clips, and crimp terminals—each of which is a critical detail that determines the product’s overall protection rating, vibration resistance and anti‑loosening performance, and sealing durability. The quality of even these small parts directly impacts the connector’s overall service life.

Customized multi-core aviation connector solutions continue to expand, meeting the diverse connectivity requirements of specialized equipment.
Multi‑core aviation connectors, with their high protection ratings, vibration resistance, and integrated multi‑channel power and signal transmission capabilities, are widely used in automotive thermal management systems, industrial control cabinets, and specialized electromechanical equipment. In response to the non‑standardized design requirements of OEMs, custom‑designed multi‑core aviation connectors can flexibly accommodate variations in pin count, current rating, protection level, and locking mechanism, delivering tailored electrical interconnection solutions.

The refrigeration system sight glass has been completely redesigned to enable visualized operation and maintenance monitoring of pipeline conditions.
Refrigerant sight glasses are a classic, fundamental monitoring component in refrigeration systems. Installed on the refrigerant circulation lines, they allow operators to visually assess the refrigerant level, the presence of air bubbles, and the return flow of lubricating oil—without having to disassemble the piping. Some models, which also incorporate a humidity‑indicator function, can further gauge the moisture content within the system. They are widely used in heat pump units, central air-conditioning systems, and refrigeration units for cold storage facilities.

The sensor connector has undergone iterative upgrades, ensuring the signal chain of temperature-controlled cooling equipment remains precise and stable.
Modern refrigeration and thermal management systems rely on a large number of pressure and temperature sensors to collect real-time operating data, enabling functions such as automatic speed control, overload protection, and intelligent temperature regulation. As an intermediary connection component between the sensor and the main control system, the sensor connector integrates signal transmission, mechanical fixation, and media protection, serving as a small yet critical part of the equipment’s intelligent control chain.

Structural optimization of the terminal block in semi‑hermetic compressors lays a solid foundation for the long‑term reliable operation of commercial refrigeration equipment.
Semi‑hermetic compressors are widely used in high‑power refrigeration applications such as large cold storage facilities, commercial central air‑conditioning systems, and industrial chillers. These units operate continuously year after year under conditions of significant load fluctuations and demanding, complex operating environments. As the critical interface for external electrical connections, the terminal block must meet industry standards that far exceed those for household appliances, with stringent requirements for insulation performance, mechanical strength, and vibration‑resistance durability.

Performance upgrades to terminal blocks for home appliance air-conditioner compressors are driving the next‑generation evolution of high‑efficiency refrigeration appliances.
Against the backdrop of the comprehensive implementation of new energy-efficiency regulations in the home appliance sector, household refrigeration appliances such as air conditioners and air-source heat pumps are continuously upgrading their energy efficiency ratings. As the compressor serves as the core component determining the overall energy consumption of the unit, the quality of its internal electrical connection components significantly impacts the product’s service life, safety, and operational stability. The compressor terminal block is an indispensable key part in this regard.
