A backshell is a protective accessory designed to attach to the rear of an electrical connector. Its primary role is to safeguard the cable termination area, offering crucial support and protection where the cable connects to the pins or sockets of the main connector body.
The main functions of backshells include providing robust strain relief to prevent cable damage from bending or pulling, ensuring effective environmental sealing against moisture, dust, and other contaminants, and delivering essential EMI/RFI shielding to maintain signal integrity by mitigating electromagnetic interference.
Though often paired together, a backshell and an electrical connector serve different purposes. Connectors enable the electrical interface by housing the contacts. A backshell, on the other hand, mounts to the rear of the connector to provide cable protection, strain relief, and shielding. It doesn’t conduct signals but is vital for ensuring the overall durability and performance of the connection—especially in rugged or demanding applications.
Choosing the right backshell depends on several factors: connector compatibility (e.g., MIL-DTL-38999), required environmental sealing, EMI/RFI shielding needs, cable exit angle (straight, 45°, or 90°), and the termination style (e.g., banding, heat shrink, or clamps). High-quality datasheets and compatibility guides, such as those from EMCA, help ensure the backshell meets both technical and environmental demands.
Backshells are used in environments where connectors need additional protection from physical stress, environmental hazards, and electromagnetic interference. Common applications include aerospace, industrial automation, rail, marine, and defence systems—anywhere reliable cable management and shielding are critical to system performance.
At EMCA, we offer a wide range of backshells designed for high-reliability applications—from EMI/RFI shielded backshells to environmental sealing variants. Our product lineup includes straight, 45°, and 90° backshells compatible with connector series such as MIL-DTL-38999 and MIL-DTL-26482. Explore specific product series like Series A3 to find the right solution for your application.
