As aircraft become ever more electrically powered from the increased presence of electronics to the advent of hybrid propulsion systems, a great number of Electrical Connectors are needed for establishing the circuits needed for transferring power. With a large cable assembly present in many aircraft for powering flight critical instruments and systems, protecting such cables is extremely important. While many may take actions to ensure cables are not bent or damaged, an extremely important section of the cable that is often overlooked is the electrical connector and its backshell.
An electrical connector is a type of electromechanical device that may be used to join together conductors in order to establish a circuit, and the backshell of the cable assembly is what contains the wiring and cable housing. Aircraft backshell components are typically installed near the rear end of the connector, regardless of whether the connector is male or female. The Backshell Aviation part is critical for protecting Cable assemblies
and circuits, as the shell can shield the component against physical damage, mechanical stressors, and electrical interference. To accommodate the connection of an electrical cable, the backshell may allow for the attachment of an electrical cable clamping device. In some cases, the backshell aviation part may even contain its own clamping device that is built-in. Depending on the amount of wires needed to establish a connection for a circuit, the clamp may be manufactured in various sizes.
When searching for aircraft backshell components for a specific application, there are various factors that should be considered to ensure that the right fit is chosen for your needs. The first and foremost consideration when searching for a Backshell aviation part is establishing its use, as more complex applications may require more performance capabilities and offerings from the backshell. When considering the implementation of the backshell, one can quickly determine what connector type they may need, ensuring that the size and shape will accommodate the application in question. Furthermore, the diameter of the cable should be also taken into consideration in order to fit the entire assembly within the confined space of the aircraft.
While the type, size, and shape of cables are all important considerations, one of the most important factors that will decide which backshell components are best for your application is the environment in which they will be placed in. Depending on the placement of cables and components, such items may be subject to extreme conditions and can be affected by strain, moisture, electromagnetic interference, heat, and much more. As such, the environment will determine whether you are in need of an environmental, non-environmental, environmental EMI/RFI, or non-environmental EMI/RFI backshell component.
The environmental backshell electrical connector
types is most often used in extreme environments, and they are typically fitted with environmental sealing after the backshell is secured. As such, the backshell aviation part can withstand dust, salt, temperatures, moisture, fluids, and more. When such conditions are not present, as is with a climate-controlled room, a non-environmental backshell connector type is used. Such types also assist in situations where there needs to be more space for networks, service loops, cable routing restrictions, and more.
With an environmental EMI/RFI type, backshell connectors can be protected from electromagnetic Interference (EMI) and Radio Frequency Interference (RFI), all while still shielding themselves from standard environmental factors. Such EMI and RFI protection is critical for cable assemblies that are placed in certain environments throughout the aircraft, as such interference often originates from electromagnets, motors, broadcast stations, fluorescent lighting, coils, and other types of communications circuits. With the non-environmental EMI/RFI type, EMI and RFI protection is provided without shielding from standard environmental factors.
