Connectors play a role in the "nervous and vascular system" in aerospace. They are responsible for achieving reliable power transmission, signal control, and data exchange between various systems, devices, and components. In extreme and high-risk flight and space environments, the performance of connectors directly affects personnel safety and mission success or failure.

The application of connectors covers every corner of aircraft, and the following are some core application areas:

avionics system

Description: This is the most concentrated area of connectors. Flight management computers, radar systems, communication radios, navigation devices (such as GPS, inertial navigation), cabin display systems, etc. all require a large number of connectors to interconnect.

Function: Transmit high-speed data signals, control signals, and low-voltage power supply. Ensure real-time and accurate transmission of information.

Power system (engine)

Description: Modern aircraft engines are highly intelligent systems with a large number of sensors and actuators.

Function: The connector is used to transmit various parameters of the engine (such as temperature, pressure, speed, vibration) to the control computer, and transmit control commands to components such as the fuel regulator and actuator. They must be able to withstand extremely high temperatures, severe vibrations, and oily environments.

Body wiring system

Description: As a node of the aircraft's "neural network", connectors gather cables scattered throughout the fuselage into bundles and achieve modular connections through connectors.

Function: Simplify the assembly and maintenance process. When it is necessary to replace a component (such as navigation lights on the wings or cabin door sensors), simply disconnect the corresponding connector without rewiring.

flight control system

Description: The connector connects the control lever of the cockpit, the pedal to the wing, and the rudder actuator on the tail wing.

Function: Transmit crucial flight control commands. This type of connector requires the highest level of reliability, and any failure could lead to catastrophic consequences. In modern fly by wire systems, digital signals are transmitted.

Environmental Control System and Cabin System

Description: including air conditioning, pressurization, lighting, entertainment system, kitchen equipment, etc.

Function: Transmit power (including high-voltage AC) and control signals to ensure passenger comfort and the normal operation of cabin equipment.

Military and Aerospace Special Applications

Missiles and UAVs: Using lightweight and highly reliable connectors, often requires a "separation after launch" function.

Satellites and spacecraft: must be able to withstand the enormous impact and vibration of rocket launches, as well as extreme temperatures, high vacuum, and strong radiation environments in space.

Spacesuit: Used to connect life support systems with spacesuits, transmit physiological data, communication signals, and electricity.
