Application of connector in UAV

Application of connector in UAV

Connector is an important basic component which is almost ubiquitous in military application systems such as aviation and aerospace, and the aircraft(Aircraft) As well as the avionics system is the largest and most concentrated application field of military connectors, connectors in the aircraft and avionics system plays a role in the transmission of signals or transmission power interconnection. Drone(Unmanned Vehicles,UV)Due to the increasingly prominent advantages in intelligence reconnaissance, target capture, target attack and other aspects, it is more and more important for national defense, so it has become a weapon and equipment vigorously developed by military powers. Compared with manned aircraft, the degree of intelligence is high, the technology is more complex, and the working environment is worse, so the components including connectors are more demanding.

Drone designers must specify high-performance interconnect technologies, suchMIL-DTL-38999(Environment resistant fast separation high density small circular connector),MIL-C-26482(Environment-resistant fast separation high reliability circular connector)or other military connectors. These high-performance connectors enable drone designers to achieve the following goals: increase operating life, reduce installation and maintenance costs, reduce testing and qualification costs, and improve reliability and safety.

Typical electronic systems for connectors used in military drones include: engine control and sensors, landing/Docking systems, flight control, fuel cell sensors, data processing and navigation, and payload technologies such as high-definition infrared camera systems, high-speed image processing, dedicated security data communication electronics, target and fire control(Weapons)System, mine detection, sonar, radar or radio.These electronic systems are generally equipped with military standard socket connectors for easy installation into drones. UAVs specify high-performance rectangular and circular connectors with various structures, suchMIL-DTL-38999SeriesIII,MIL-DTL-83513 (MiniatureDForm)and other military connectors. UAV interconnection system engineers improve the key characteristics of the wiring system and/Or one of the best opportunities to reduce the size and mass is to change the drone.“black box”Technical conditions for connectors on payloads and other electronic devices. The correct choice of connectors on the black box allows engineers to specify cable harnesses with reduced size and mass to connect the drone's subsystems, which gives the drone performance and size/Quality requirements.

Glenairof micro-miniatureDForm(Figure7)withSouriauDifferent, the stranded wire pin contact is used.(Figure7), It is more secure than stamped and formed contacts, and provides an excellent wire fixing method with lower contact resistance. The stranded wire pin wire fixing sleeve also allows air-tight crimping, ensuring excellent tensile performance And the circuit resistance is lower than the stamped sleeve. The company's micro rectangular connectors are extremely small in shape and quality, but still maintain the best performance under harsh conditions.GlenairMiniature rectangular connectors are widely used in many UAV programs, such as including“predator”,“Shadow”,“Attendant”,“Fire Scout”Recently, IsraelInstituteCompany DesignationGlenairCompany custom-designed micro-miniatureDshape connector for its second generation“Search Eagle”On the blind-plug wing joints of the UAV, as well as the propulsion system and remote controller of the UAV.

The micro rectangular electrical connector series such as J30J produced by Adra are of good quality, strong function and advantageous price. Welcome to consult and order!
