As a core equipment of aerospace engineering, the on-orbit operation stability of satellites directly determines the success or failure of missions, and the interconnection reliability of precision electronic equipment inside satellites is a key support. From the command transmission of on-board embedded computers to the collection and circulation of telemetry data, every connection must withstand the test of the extreme space environment, imposing extremely high requirements on the airtightness, miniaturization, and anti-interference ability of connectors. Ankeno, deeply engaged in the field of high-end precision connectors, has independently developed the J20JM1 series glass-sintered hermetic electrical connectors. With precise performance matching and technological advantages, it has been successfully applied to the internal interconnection of multiple satellite models, becoming the “connection cornerstone” for the reliable operation of satellites.

During on-orbit operation, satellites need to withstand extreme temperature differences of -55℃ to 125℃, continuous vibration of 10-2000Hz, and impact of 980m/s² for a long time. At the same time, the strict weight control of the limited space inside the satellite requires connectors to be miniaturized, lightweight, and highly reliable. Traditional connectors often struggle to balance airtightness and high-density transmission requirements, and are prone to poor contact, gas leakage and other problems, affecting the normal operation of core systems such as satellite attitude and orbit control and energy management. The development of Ankeno J20JM1 series connectors is precisely to solve this industry pain point, tailored for high-reliability scenarios.

In the scenarios of inter-board and through-wall connections inside satellite cabins, the core advantages of J20JM1 series connectors are fully exerted. This series of products adopts glass sintering technology, and the socket is hermetically sealed, with an air leakage rate not exceeding 1.01×10⁻³Pa·cm³/s, which is strictly verified by helium mass spectrometry leak detection. It can effectively isolate vacuum, dust and other impurities in the space environment, prevent erosion of precision electronic components inside the satellite, and ensure long-term stable operation of equipment, which is highly consistent with the strict requirements of satellite integrated electronic systems for sealing protection.

To meet the needs of satellite miniaturization and high-density interconnection, the J20JM1 series connectors adopt a compact design, with a contact spacing of only 0.95mm and a row spacing of 1.01mm. The entire socket is gold-plated, which not only improves electrical conductivity and corrosion resistance but also greatly reduces installation space. The product provides nine specifications from 5 to 37 cores, which can be flexibly selected according to the transmission needs of different electronic modules of the satellite, perfectly adapting to the modular connection needs of the centralized or distributed architecture of on-board embedded computers, and realizing efficient transmission of commands and data.

The high reliability requirements of satellites run through the entire life cycle, and the J20JM1 series connectors fully meet the performance standards. The supporting plug adopts a stranded elastic pin (twisted pin) design, which has soft insertion and extraction and stable contact. The cross-sectional area of the plug wire core is 0.07mm², balancing transmission efficiency and lightweight requirements; the tail end of the contact adopts gold wire bonding technology, which further improves connection reliability and ensures stable electrical performance even in harsh vibration environments. Its contact resistance is ≤15mΩ, insulation resistance ≥5000MΩ, and rated current 2A, which can stably transmit key signals such as satellite telemetry and remote control, with a mechanical life of 500 times, meeting the plug-in needs of on-orbit satellite operation and maintenance.

As a high-reliability connector positioned at the military level, the J20JM1 series strictly implements the enterprise standard Q/HLJ-037-2024, and has passed multiple rounds of extreme environment tests, fully adapting to the complex working conditions of satellite on-orbit operation. At present, this series of products has been successfully applied to the internal interconnection scenarios of small satellites and medium-sized spacecraft, providing reliable connection support for the stable operation of on-board electronic equipment, and effectively reducing the risk of satellite on-orbit failures.

From satellite launch and orbit insertion to long-term on-orbit operation, every precise command transmission and every complete set of telemetry data is inseparable from the silent support of J20JM1 series connectors. With technological innovation as the core, Ankeno continues to deepen its efforts in the field of high-end precision connectors, providing high-reliable and high-precision connection services for satellites and other aerospace equipment through customized solutions, helping the high-quality development of China’s aerospace industry.
