Products in this family are used for the construction or repair of D-subminiature (D-Sub) cables, so named because of the D-shaped shroud surrounding their mating region and the relatively high interconnect density they offered at the time of their introduction. These products serve to enclose the junction between the conductors in a cable and the contacts in the connector assembly, providing cable strain relief and facilities for mechanical fixation.

About D-Sub, D-Shaped Connectors - Backshells, Hoods
What are D-Sub, D-Shaped Connectors - Backshells, Hoods?
D-Sub, D-Shaped Connectors - Backshells, Hoods
D-Sub, D-Shaped Connectors - Backshells, Hoods are essential components in the realm of electronic connectors, specifically designed to provide mechanical support and protection to D-Sub connectors. These components serve as protective covers that encase the connector's rear, safeguarding the cable connections from physical damage, electromagnetic interference, and environmental factors. By securing the cable to the connector, backshells and hoods ensure a stable and reliable connection, enhancing the overall performance and longevity of the electronic system. Their design typically involves a D-shaped metal or plastic shell that aligns with the connector's shape, facilitating easy assembly and disassembly.
Types of D-Sub, D-Shaped Connectors - Backshells, Hoods
Metal Backshells: These are crafted from robust materials like aluminum or zinc, providing excellent shielding against electromagnetic interference (EMI) and radio frequency interference (RFI). They are ideal for applications requiring high durability and protection in harsh environments.
Plastic Hoods: Lightweight and cost-effective, plastic hoods are suitable for applications where EMI/RFI shielding is not a primary concern. They offer basic protection against dust and physical damage, making them ideal for consumer electronics and office equipment.
EMI/RFI Shielded Backshells: These specialized backshells incorporate additional shielding materials to enhance protection against electromagnetic interference. They are used in sensitive applications such as aerospace and military communications where signal integrity is paramount.
Right-Angle Backshells: Designed to facilitate cable routing in confined spaces, right-angle backshells allow cables to exit at a 90-degree angle, optimizing space and reducing strain on the cable connections.
How to choose D-Sub, D-Shaped Connectors - Backshells, Hoods?
When selecting D-Sub backshells and hoods, consider the following key parameters:
Material: Choose between metal and plastic based on the required level of EMI/RFI shielding and environmental protection.
Cable Exit Orientation: Determine whether a straight or right-angle exit is more suitable for your application.
Size and Compatibility: Ensure the backshell or hood is compatible with the connector size and pin configuration.
Environmental Considerations: Assess the operating environment for factors such as temperature, humidity, and exposure to chemicals.
Supplier Evaluation: Research suppliers for product quality, reliability, and compliance with industry standards. Look for certifications and customer reviews.
By carefully evaluating these parameters, you can select the most appropriate backshell or hood to meet your specific application needs, ensuring optimal performance and longevity.
Applications of D-Sub, D-Shaped Connectors - Backshells, Hoods
Aerospace: In aerospace applications, these connectors are used in avionics systems to ensure secure and interference-free connections. Their robust design withstands extreme conditions, providing reliable performance in critical flight operations.
Military and Defense: D-Sub backshells and hoods are employed in military communication systems, where they offer enhanced EMI/RFI protection and durability, crucial for maintaining secure and uninterrupted communications in the field.
Industrial Automation: In industrial settings, these components are used in machinery and control systems to protect connections from dust, moisture, and mechanical stress, ensuring consistent and efficient operation.
Telecommunications: In telecom networks, D-Sub connectors with backshells and hoods are used to maintain signal integrity and protect against interference, supporting reliable data transmission across vast distances.
Medical Equipment: These connectors are integral to medical devices, where they ensure stable and secure connections, crucial for the accurate functioning of diagnostic and monitoring equipment.
