Introduction

Circular connectors and adapters are important components used in various fields, such as military and industrial applications. The TBF 20-19 PSW series is a specific type of circular connector and adapter that has been effectively used in many applications. This article will discuss the application fields and working principle of the TBF 20-19 PSW series.

Application Fields

The TBF 20-19 PSW series are commonly used for network or computer connections, motor control systems, and other industrial instrumentation connections. It is mainly utilized in government and military applications, as well as commercial and industrial settings since it provides robust and reliable connection. The TBF 20-19 PSW series are also suitable for use in special applications, such as in hazardous areas like oil and gas facilities, automotive and special process control systems, drilling rigs, instrumentation and data acquisition systems. In addition, the TBF 20-19 PSW series are certified to meet all US Military standards, which makes them particularly suitable for use in military systems.

Working Principle

The TBF 20-19 PSW series are a two part interchangeable system. The first part is the plug assembly which contains contacts and an internal plastic dielectric insulator. The second part, the adapter, is a receptacle or socket that mates with the plug assembly. The plug assembly and adapter are secured together with a combination of locking clips, screw threads, and keyways. The contact in the plug assembly are gold plated and have an operational voltage of 1500 V, and an operational temperature range of -40° to +85° Celsius. The adapter contains the contact receptacles, which provide electrical termination for the contact in the plug assembly. In addition, the strain relief in the TBF 20-19 PSW series involves a metal spring located in the plug assembly, which exerts inward pressure against the adapter to ensure a secure interlocking connection. This ensures a secure connection between the plug assembly and the adapter and helps to protect the contacts against impacts or vibration.

Conclusion

The TBF 20-19 PSW series are a type of circular connector and adapter that are suitable for use in a range of different applications, including military and industrial applications. Its working principle involves a two-part interchangeable system which is secured together with a combination of locking clips, screw threads, and keyways. The plug assembly is gold-plated and has an operational voltage rating of 1500 V, and the adapter contains contact receptacles to provide electrical termination for the plug assembly contacts. Additionally, the strain relief feature helps to ensure a secure interlocking connection.
