D-Subminiature, or “D-Sub”, connectors are a family of electrical connectors commonly used in electronic equipment. A specific example from the family of D-Sub connectors is the 962-025-030R121 backshell or hood. This backshell style is designed to protect exposed pins and terminals when used in a wire-to-board, cable-to-board, or cable-to-cable application.

The 962-025-030R121 includes a wire segmented strain relief for cable-to-board applications and can accommodate modular plugs, male, and female connectors. The strain relief can also be removed and replaced with a terminal block for a wire-to-board application. It provides 360° EMI/RFI shielding coverage for optimal shielding of the assembly from the environment.

This backshell or hood is designed to fit standard D-Sub D-shaped connectors. The sides of the hood have a tapered shape that matches the shape of the pins on the connector. The 962-025-030R121 has knurled steel nuts that provide easy grip for connection and a locking mechanism to securely hold the hood onto the connector. It also has a mounting flange to attach the hood to the mating surface of the device.

The working principle of this style of backshell or hood is simple. First, the cables should be installed in the strain relief as required. Then, the hood should be attached to the assembly. Once the hood is securely fastened, strain relief segments should be locked into place. Lastly, the EMI/RFI shielding material should be applied over the hood opening to provide the necessary electromagnetic interference and radio frequency interference shielding.

The 962-025-030R121 D-Sub connector backshell or hood is a highly durable part and can be used in applications where there is considerable vibration and shock. It is suitable for a wide range of operating temperatures, making it an ideal choice for a variety of applications. Its universal design and strain relief ensure that connector and cable integrity is maintained regardless of the application.
