Circular Connectors - Backshells and Cable Clamps

Circular connectors, also known as backshells and cable clamps, are designed to provide strong, reliable electrical connections. The primary purpose of circular connectors is to provide an electrical interface between components, devices, and systems. The devices are typically used in the automotive, medical, aerospace, and military industries, as well as in industrial applications.

BLL1ASL18039XW Application Field

The BLL1ASL18039XW circular connector backshell is designed for military, industrial, and commercial applications. It is a multi-contact connector that has been tested to MIL-PRF-87989 and is ideal for high temperature and harsh environment applications. Its features include an integrated strain relief system for easy assembly, high temperature and fire retardant protection for optimal performance, a high cycle/fatigue life for robustness, and a reliable mil-spec 5-pin connector. This connector is suitable for use in applications such as military communications systems, automotive applications, industrial machinery, and many other high-temperature and harsh-environment applications.

BLL1ASL18039XW Working Principle

The BLL1ASL18039XW circular connector backshell is composed of five terminals which are connected by a backpanel. Each terminal is constructed of two layers of insulation and a wire. The outer layers of the terminals are used to provide strain relief, while the inner layers are used to connect the terminals to the backpanel. The terminals are held in place by a mounting nut. This nut is used to connect the terminals to the backpanel, allowing for the exchange of electrical signals between the terminals and the backpanel. The terminals are also insulated from each other to prevent electrical shorts. The terminals are connected to the backpanel via a pin and socket connection that ensures a reliable connection. When the terminals are connected to the backpanel, they are kept together with an outer sleeve which is designed to provide strain relief. This outer sleeve also helps prevent the spread of sparks and heat, protecting the terminals from damage and ensuring the reliability of the connection.

Conclusion

The BLL1ASL18039XW circular connector backshell is designed to provide strong, reliable electrical connections for the military, industrial, and commercial applications. It is designed with an integrated strain relief system for easy assembly, high temperature and fire retardant protection, and high cycle/fatigue life for durability. The terminals are held in place by a mounting nut which is used to secure the terminals to the backpanel. The terminals are connected to the backpanel via a pin and socket connection that ensures a reliable connection and the outer sleeve provides strain relief.
