Circular Connectors - Backshells and Cable Clamps

Circular connectors and backshells have been around for decades, and are still in use today. They’re available in both plastic and metal varieties, and are used in a variety of applications from military and aerospace to consumer electronics. The type of backshell used for a given application depends on the particular type of connector, its environment, frequency, and other factors. In this article, we’ll take a closer look at the 218M620D19B – a popular type of circular connector – and its application field and working principle.

218M620D19B Application Field

218M620D19B circular connectors have a wide range of applications in a variety of electronic systems. They’re typically used for low-voltage, low-frequency electrical connections in both military and commercial applications. 218M620D19B connectors are often used in data communication systems, radio systems, radar systems, and portable electronic devices. They’re also used in medical devices, machine vision systems, and other industrial applications. They’re also used to connect audio and video equipment, and are rated to the applicable MIL-DTL-22992.

Principles of Operation

The 218M620D19B is a screw-on type of circular connector. The connector is designed for use with both power and signal cables. It consists of two parts – the male connector and the female plug. The male connector has two contact screws that secure the cables in the sockets. The female plug also has two contact screws that secure the cables in the plugs. When the connector is connected, the contact screws pull the cables together and make electrical connections.

The 218M620D19B has an internal waterproof protection ring which helps to protect against dust and water intrusion. It also has an external nut thread which allows for an easy and secure connection. The 218M620D19B has gold plated connection contacts for better conductivity and corrosion resistance. It also has EMI/RFI shielding capabilities to help keep out electromagnetic interference.

Backshells and Cable Clamps

In addition to the 218M620D19B connector, there are several other types of backshells and cable clamps available. These devices are designed to meet specific application requirements, such as strain relief, EMI/RFI shielding, environmental sealing, and more. Strain relief clamps provide flexibility and vibration resistance, while EMI/RFI backshells provide shielding against electromagnetic interference. There are also environmental backshells that provide weather-resistant sealing. Cable clamps, on the other hand, can be used to secure a cable to a connector or backshell, and can also provide strain relief and environmental sealing.

Conclusion

The 218M620D19B is a popular type of circular connector used in a variety of applications. It offers advantages such as waterproof protection, gold plating, and EMI/RFI shielding. In addition, there are several other types of backshells and cable clamps available to meet specific application requirements. By carefully selecting the appropriate type of circular connector and backshells, you can ensure a reliable and secure connection for your electronic systems.
