Circular Connectors - Backshells and Cable Clamps

Circular connectors, consisting of backshells and cable clamps, are device components used to securely join two components such as inputs, outputs, or mechanical couplings. These connectors are often found in electronic devices, including computers, televisions, audio systems, and servers, allowing pins and electrical wiring to connect to the device chassis. Backshells and cable clamps act as protective measures against environmental elements, mechanical stress, and undue strain.

TXR21AB45-2216AI Application Field and Working Principle

The TXR21AB45-2216AI is a circular connector backshell designed and manufactured by TE Connectivity. It fits most cylindrical connectors with up to 16 contacts, and consists of a dielectric walls forming a protective shield over the rear of the connector, its contacts, and interconnect wiring. This backshell designed for circular connectors features an EMI/RFI shield which helps reduce electrical noise. It is designed to work with various TE and other connectors such as M83723/14, M23168/19, etc.

TXR21AB45-2216AI circular connector backshells are designed to prevent interference from outside electromagnetic fields and maintain a secure connection at all times. Though varying in features, the general form of a connector backshell includes a strain relief cable clamp, decoupling or roll-off sleeve, fitting, filler plug, and pins or other contact fittings. It is highly customizable for ergonomicl, mechanical, and environmental requirements. The primary purpose of the backshell is to both protect the connector from outside influences such as dust or humidity as well as to secure the inside wiring and contacts.

Connectors can also be customized for environmental conditions such as extreme temperatures or hazardous atmospheres. EMI/RFI shielding is available and can be implemented to prevent electromagnetic or radio interference on the device and keep it running smoothly. Additionally, these backshells are highly flexible for different applications, from medical equipment, aerospace, automotive, and non-automotive applications. The backshells are additionally RoHS compliant, meaning it contains no hazardous substances such as lead, cadmium, and mercury, a design feature beneficial for a wide range of industries and applications.

Conclusion

Circular connectors including backshells and cable clamps play an integral role in connecting two components. The TXR21AB45-2216AI circular connector pin backshell is designed to provide a secure connection for up to 16 pins in various digital devices. It includes features such as EMI/RFI shielding for reduced noise interference, as well as a strain relief cable clamp for external protection. It is RoHS compliant, making it an ideal connector for various industries that are looking for a safe and secure connection.
