Barrel - Audio Connectors: RCJ-2221 application field and working principle

Barrel - Audio Connectors play an important role in the field of audio system. The RCJ-2221 series of connectors are well designed for audio transmission application and prove to be the ideal choice for these applications. It is a widely used connector type that is designed for balanced differential audio requirements and provides excellent noise performance capability.

The RCJ-2221 connector is suitable for both unbalanced and balanced audio systems. It is often used for connecting speakers, headphones, active speakers, amplifiers, and other audio devices in audio systems. The connector has a bayonet-type locking mechanism which provides reliable connection and allows it to be connected securely in high-vibration environments. Moreover, the connector has a sleek and modern design which makes it suitable for use in high-end audio products.

The working principle of the RCJ-2221 connector is based on what is known as a three-pole terminal configuration. It consists of two plastic shells that form the base of the connector. The shells must be connected together to form an outer shell. Then, the shells are connected to the signal terminals, which are the positive, negative, and shield poles.

In addition, the RCJ-2221 connector utilizes an additional contact for the shield connection. This contact contacts with the inner-layer insulation of the cable which provides additional noise protection. In addition, the contact has a finger-grip design which allows for easy connection.

Overall, the RCJ-2221 series of connectors provide excellent performance in audio systems. They are an ideal choice for professional applications and offer reliable connection and excellent noise performance. Moreover, the sleek and modern design makes them suitable for use in high-end audio products. It is thus a widely used connector type in the field of audio system.
