D-Sub, D-Shaped Connectors are sets of connectors and components that integrate together to follow a standardized D-shaped housing which is typically made of plastic. The “D-shaped” shape of the housing gives the connectors its name. Such connectors are particularly useful for connecting high-voltage electrical equipment to each other and is often found in industrial and consumer electronics projects. Backshells, hoods, and other components are necessary to complete the package.

986-037-020-121 is a D-Shaped Connector that is composed of both a shell and hood. The shield shell is utilized to mechanically retain the contacts, it also provides strain relief, and for Electro-Magnetic Interference (EMI/RFI) protection. It features a polarizing slot positioned along the back of the connector housing to prevent non-keyed mating. The mating hood adds a measure of touchproof (IP65) protection to the completed assembly.

This particular product is a 2-ply shield backshell and hood system that is designed for use with computer I/O cables. It is available in four sizes (250, 381, 507, and 652). The backshell is designed to accept respective mating connectors and is suitable for applications such as Ethernet, USB, HDMI, VGA, IEEE 1394, and a variety of others. Some of the features that the product offers are multi-directional strain relief, 360-degree EMI/RFI shielding, and dust protection. It is made with a zinc alloy material and features a black finish that is designed to prevent any corrosion.

The working principle of the 986-037-020-121 is quite simple yet very effective in ensuring the connection of the I/O cables. It is organized to ensure proper orientation of both the cable and the connector. To start, the shielding of the 986-037-020-121 is positioned along the inside of the connector behind the connector retention flange. This feature provides shielding for the connector from electrical and electromagnetic interference. Next, the wire leads are inserted into the connector using the polarization slot, providing polarization of the connector to prevent misalignment. Once the wires are in place, the backshell is then placed over the cable to provide strain relief and mounting. Finally, the hood is then placed on over the assembly to provide a dustproof and touchproof connection.

Overall, the 986-037-020-121 is an extremely versatile connector that is designed for a number of applications, ranging from Ethernet to USB. It is easy to use, as its working principle is quite straightforward, and is designed to provide an effective solution for shielding and strain relief. This product is an excellent choice for any project requiring a reliable connection of I/O cables.
