How to Choose the Right Backshell?

Finding the right connector solutions can be a complex task, requiring an individual to be aware of the various connector types, power ratings, connector genders, and more. While choosing the right connector is important, so too is having a connector with ample protection. For the safety of a connector, its contacts, and cable, accessories known as backshells are commonly added for reducing environmental and mechanical stress. There are a variety of backshell types, each of which may cater towards certain applications or environments that they excel in. To help you best understand the importance of such connector components, we will provide a brief overview of their functionality, uses, and types.

As stated before, backshells are a protective accessory that are added to connectors, and they may come in a variety of sizes, shapes, and materials. To be attached to a connector, backshells will often utilize a clamp or moulded boot, though threading may also be used for connecting to a mating receptacle. When deciding on a backshell connector component for a particular need, one should first consider how the interconnect solution will be used. Additionally, one should also determine the environment that a connector will be placed in, the type of connector used, cable diameters, space restrictions, and rating requirements.

Backshells typically come from one of four families, those of which include non-environmental, environmental, non-environmental EMI/RFI, and environmental EMI/RFI types. Basic non-environmental backshells are for standard environments where climate is either controlled or where there is no harsh environment present. Without environmental protection, such backshell types will often provide strain relief. Environmental backshell connector accessories are best for when there may be dust, moisture, dirt, or highly fluctuating temperatures present within an environment which may pose a risk to connectors. With such types, environmental sealing is achieved after the strain relief of the component is secured.

In some applications, connectors may be at risk of exposure to Electromagnetic Interference (EMI) or Radio Frequency Interference (RFI), both of which can have a detrimental effect on signal transfers. With non-environmental EMI/RFI backshell components, connectors and their signals can be protected from such interferences while in a controlled environment. As a result, such backshell types are often used alongside connectors that are placed in the presence of coils, electrical motors, transformers, high power radar equipment, and more. Environmental EMI/RFI backshells are similar in their interference protection, though also have the added benefit of environmental protection as well.

Once the general type of backshell has been determined, there are also a variety of shapes, sizes, and other considerations that may be made to further accommodate an application. Depending upon the space and its requirements, 45 degrees, 90 degrees, and straight backshell accessories are all types that may be used. Furthermore, backshell adaptor components may be useful as well, providing more compatibility to certain connectors and components for the benefit of strain relief. Beyond space requirements, other important considerations one may make include routing requirements, coupling styles, and whether or not accessories are needed.
