Features:
- Precise Mechanical Structure: - The precise structural design ensures that the threaded connection of the connector is tight and reliable, preventing loosening under vibration or shock conditions. Meanwhile, the connector pins and jacks are machined with high precision to ensure good electrical contact. - With certain mechanical strength, they can withstand the mechanical stress during installation and use and are not easily damaged.
- Strict Quality Control and Inspection: - The production process follows a strict quality management system, and each production step is strictly inspected and controlled to ensure that the quality and performance of the products meet the aerospace standards. For example, the electrical performance, mechanical performance and environmental adaptability of the connectors will be thoroughly tested and verified. - A series of reliability tests, such as temperature cycling test, thermal vacuum test, vibration test, mechanical shock test, etc., will be carried out before leaving the factory to simulate the space environment to evaluate the connectors.
- Lightweight design: - On the premise of meeting the performance requirements, the weight of the connector is reduced as much as possible to lower the total weight of the spacecraft and improve the launch efficiency and operational performance of the spacecraft. For example, adopt lightweight materials or optimize structure design to realize lightweight.
Application:
- Space science experiment loads:
- Experiment instrument connection: some instruments in the space science experiment load need to collect and transmit RF signals, and SMA connectors can be used to connect the RF modules of these instruments, such as spectrometers, imaging equipment, etc., to ensure the accuracy and reliability of the experiment data.
- Sensor signal connection: some sensors output signals for RF signals, SMA connectors can be connected to the sensor and signal processing circuits to transmit the information detected by the sensor.
2. Commercial Space Field:
Satellite Internet: In commercial satellite Internet projects, a large number of satellites need to be deployed in space, SMA connectors are used for communication connections between satellites and between satellites and ground gateways to support high-speed data transmission.
Space Tourism Facilities: In future space tourism related facilities, such as communication and entertainment systems inside the space capsule may also need to use SMA connectors to connect related RF equipment.
