The 75th International Astronautical Congress is currently underway at the Milan Conference Center in Italy, which opened on October 14, 2024, and will last for five days. One of the major highlights of this year's congress is the display of lunar soil samples from China's Chang'e 6 mission, which were collected from the far side of the Moon. This marks the first overseas appearance of these lunar samples, generating significant excitement at the event. Christine F. K. P. Fichtinger, Executive Director of the International Astronautical Federation, remarked that global space exploration without China's involvement is "hard to imagine" today, and praised China's open attitude toward international cooperation.
China’s ability to attract attention and acclaim both domestically and internationally is a testament to the rapid development of its space program, with every successful launch underscoring the tremendous efforts of countless Chinese scientists, companies, and people. Slip rings and rotary joints are essential components in these spacecraft's control systems, gimbals, and solar panels, ensuring stable power and signal transmission for various devices and systems.
As a well-established slip ring manufacturer with nearly 30 years of experience in independent research and production, JINPAT possesses rich expertise in developing high and low-temperature resistant signal transmission modules. We offer excellent slip ring solutions designed for the high-pressure and temperature-variable conditions of outer space. One such product is the LPT000 (specific model not disclosed), a space aerospace slip ring developed for a client, featuring a through-hole contactless high-frequency rotary joint. This slip ring offers significant advantages such as low torque, low loss, and long lifespan. The casing is made from lightweight, high-strength, and corrosion-resistant materials, ensuring durability while reducing overall weight and load on the spacecraft, thus enhancing performance and efficiency. The collector rings on both ends use aviation connectors to ensure reliable contact. Internally, a modular shock-resistant structure integrates five rotary joints, totaling 135 rings. Customer validation has confirmed that this rotary joint fully meets vibration, impact, and EMC (electromagnetic compatibility) requirements, allowing it to operate continuously and stably in harsh environments. Whether faced with extreme temperatures and pressures at high altitudes or potential exposure to rain, dust, and complex electromagnetic environments, JINPAT's slip ring demonstrates outstanding performance.
Additionally, this slip ring boasts an IP65 protection rating, is capable of operating at altitudes of 21,336 meters and above, and functions within a temperature range of -55°C to +70°C. It integrates differential signals, network signals, HD video, fiber optics, and high-frequency signals, meeting the demands for real-time data transmission and processing in modern aerospace missions. The signal and power rings also feature a physically isolated design, significantly enhancing signal interference resistance and ensuring stable transmission.
In aerospace missions, slip rings are specifically installed on rotating components of satellites to ensure continuous data transmission and command reception during operation. Applications include the rotating mechanisms of solar panels, communication antennas, and the retractable control cable spools of aviation seats. Due to the precision and specificity required in aerospace equipment, these slip rings are often customized to meet the unique demands of different devices.
