Today, electronic products are developed more and more, the requirements for connector terminals are also becoming more and more strict. When it comes to barrel - audio connectors, 1803 is one of the most popular connectors in the industry. The barrel audio connector 1803 is only 2.8mm in diameter and 10mm in length, which is much smaller than the traditional circular plug. So what kind of field is it used in, what are the working principles of it? This article will discuss the application field and working principle of 1803.

Application Field

The 1803 telssocket audio connector is mainly used in the audio industry. It is used to connect headsets, earphones, smartphones and other portable audio terminals. It is also widely used in portable electronic audio equipment such as MP3 players and digital recorders. In addition, it can also be used in computer host sound card systems, or cables for home stereo systems. This small and light audio connector can be applied in a variety of fields for various usages.

Working Principle

The barrel audio connector 1803 uses the RFI shield principle. The key component of this shield is the two-piece shielding system. The two-piece shielding system consists of a rubber sleeve and a plastic core, connected together at the ends of the connector. First, the plastic core provides shielding to the inner contacts. This shields the connector from external interference. Second, the rubber sleeve provides additional shielding by completely encapsulating the plastic core. This prevents radio frequency interference from escaping from the connector into the environment.

The 1803 also has a 3-pin system. This system includes three pins, one on the tip of the connector, one on the top and one on the bottom. The tip pin is the ground connection, the top pin is for the left audio channel, and the bottom pin is for the right audio channel. The three pins are connected to a signal cable in the center, so that sound signals can be transmitted and received through the RFI shielding system.

Conclusion

In conclusion, the barrel audio connector 1803 has excellent performance, small size and light weight, and is widely used in audio transmission fields. It uses the RFI shield principle and 3-pin detection to transmit sound signals, providing reliable and stable sound transmission. The application field and working principle of the 1803 audio connector discussed in this article will help you better understand the connector and how it works in different scenarios.
