《GB/T 43368-2023宇航用分离脱落连接器通用规范》由TC425（全国宇航技术及其应用标准化技术委员会）归口，TC425SC2（全国宇航技术及其应用标准化技术委员会宇航电子分会）执行，主管部门为国家标准委。
Introduction
Analysis of the core content of the standard
| Technical dimension | Mechanical separation type | Electromagnetic separation type |
|---|---|---|
| Separation force requirement | Axial ≤500N (15° deviation) | 24V DC/0.2s response |
| Contact resistance | ≤10mΩ (including after environmental testing) | |
| Insulation resistance | ≥1000MΩ (normal temperature) | |
Key technological innovations
Breakthrough in material system: The thickness of the gold-plated layer of the contact is ≥1.27μm, the nickel bottom layer is 1.3-3.81μm, and 17 types of hazardous substances such as cadmium/zinc are clearly prohibited (see Table 1).
Adaptability to extreme environments: Verified by 32 environmental tests including -70℃~200℃ temperature shock, 5×10⁵Gy irradiation, 1.3×10⁻⁵Pa vacuum cold welding, etc.
Implementation suggestions
- Preferably use the YF/JF series standardized interfaces to ensure model compatibility
- The electromagnetic separation device needs to be equipped with a 24V±4V/5A drive power system
- Contact crimping process control tension: 12# wire ≥489N (initial value)
Standard evolution analysis
Compared with the previous version, 12 new technical requirements are added, including optical fiber contact classification (4.1.4) and vacuum cold welding test (5.39), and the environmental sealing test pressure is increased from 0.1MPa to 0.2MPa.
