Aerospace Electrical Connectors

Aerospace Electrical Connectors

Connectors are almost everywhere in military and aerospace applications. As the interconnection of transmission signal and power, aerospace D sub space grade connectors must meet the requirements of strict outgassing and residual magnetism test to be suitable for aerospace applications.

Ground to satellite communication is a massively challenging undertaking. People need data fast, with high signal integrity, to quickly assess the message and make decisions. A poor or delayed signal may lead to a wrong conclusion or missed opportunity.

Space grade connectors have standards of MIL-C-5015, MIL-C-26482, MIL-DTL-38999, MIL-DTL-55302, MIL-DTL-83513, MIL-DTL-32139.

Application Of Aerospace Electrical Connectors

Connectors are an important basic component that is almost ubiquitous in military and aerospace aircraft & aerospace applications and serves as interconnects for transmission signals and power, which has to meet stringent testing for outgassing and residual magnetism to be suitable for use in airspace & aerospace applications , meanwhile, match for system requiresment of anti-irradiation, high-performance vacuum outgassing, adapt to ultra-high temperature and ultra-low temperature extreme environment, non-magnetic, prevent harmful gas intrusion, anti-condensation, vacuum cold welding technology.

Three Basic Types Of Aircraft D Sub Connectors Classified From A Technical Point Of View

① According to the connection modes of aircraft D sub connectors: there are threaded connection, bayonet (quick) connection, bayonet lock connection, push-pull connection and direct plug connection;
② According to the shape: aircraft D sub connectors can be circular and rectangular (cross section);
③ According to the working frequency: aircraft D sub connectors have operation types of low frequency and high frequency (with 3MHz as the boundary);

Three Types Of Technical Parameters Of Aerospace Electrical Connectors

① Electrical performance: rated voltage, rated current, contact resistance, withstand voltage and insulation resistance, shielding, RF anti-interference attenuation value;
② Mechanical properties of Aerospace Electrical Connectors: number of contact pairs and pinhole, installation mode and shape, shell material, insulator, contact, mechanical life, etc.
③ Environmental technical performance: working temperature, working height, vibration, impact, constant acceleration, leakproofness, salt fog, moisture and mould resistance, etc.

FAQ Of Aerospace Electrical Connectors

  • Q. What are the measures to ensure the reliability of space grade connectors?

    A. Select the space grade connectors listed in the list of qualified products published by the military components' management center of the national defense science and engineering commission. Carry out delivery test and secondary supplementary screening.

  • Q. What are the factors that determine the storage reliability of space grade connectors?

    A. The temperature, humidity, cleanliness and corrosive gas of the storage environment will affect the performance parameters of the space grade connectors, especially the humidity is particularly sensitive to the insulation resistance. 

  • Q. How to ensure the installation reliability of aerospace electrical connectors?

    A. The installation personnel shall first understand the technical characteristics of the electrical connector, and shall not use it under overload or overstress, and shall correctly connect and separate it according to the operation and use methods to avoid burning or damaging the electrical connector.
