D-sub backshells are essential components designed to provide mechanical support and electromagnetic interference (EMI) or radio frequency interference (RFI) protection for D-subminiature connectors. By shielding connections and securing cables, they enhance the performance and longevity of the overall connector system. D-sub connector backshells are widely used in data, signal, and power transmission applications across various industries.
A D-sub backshell attaches to the rear of a D-sub connector, enclosing the cable termination area. This enclosure serves two primary functions: Protecting the termination from mechanical strain and shielding it from external electrical interference. Most backshells include a strain relief clamp that grips the cable, reducing stress on the conductor-to-connector interface. Many options, such as low-profile D-sub backshells and right-angle backshells, are tailored for space-constrained applications or unique cable orientations.
D-sub backshells are available in several formats to meet the specific needs of different D-sub connector configurations, cable types, and environments.
This term generally refers to standard D-sub backshells that attach to D-sub connectors to provide strain relief and EMI/RFI shielding. They come in various materials, including metal and plastic, and can accommodate different cable diameters.
These backshells are compatible with D-subminiature connectors and are commonly used in computing, communication, and industrial equipment. Options include 9-pin, 15-pin, and 25-pin configurations.
High-density backshells support connectors with more pins in the same footprint as standard D-subs. These are ideal for applications requiring multiple signal paths in limited space.
Standard backshells are used with typical D-sub connectors and provide dependable protection and strain relief. They are often available in both metal and plastic versions, depending on shielding needs.
Similar to the above, these backshells are tailored for standard-size D-sub connectors, offering basic mechanical support and shielding functions.
Micro D-sub backshells, also known as sub-miniature backshells, are used in compact connectors where space and weight constraints are critical, such as aerospace or medical devices.
These specialised backshells are designed with sealing features to provide ingress protection (IP-rated), making them suitable for outdoor or industrial applications exposed to moisture or dust.
D-sub connector backshells are used to:
In environments with dense cabling or frequent movement, D-sub backshells reduce the risk of connection failure, cable fatigue, or data errors.
D-sub backshells are widely used in:
The general installation process involves:
Some variants, such as the 90-degree D-sub backshell, may have angled exits and specific alignment notches to accommodate directional routing.
