Rectangular connectors are important components in many electronic applications, especially with regards to power, radiofrequency (RF) and data transmission. The industry-standard 81020-650203 connector is commonly used for these applications. It has wide application fields and its working principle is also important to understand. In this article, the application field and working principle of the 81020-650203 rectangular connector will be discussed.

Application field of 81020-650203 Connector

The 81020-650203 connector is an industry-standard header and male pin combination. Its main application field is to transmit power, data and RF signals between two devices. It is widely used in many applications such as in electronic telegraphy, computer networks, telecommunication, electric power, and industrial control systems. It is also used in many consumer electronics, such as televisions and audio equipment. Due to its small size, the 81020-650203 Connector is ideal for connecting two devices without occupying too much space.

Working Principle of 81020-650203 Connector

The 81020-650203 connector consists of two parts: the header and the male pin. The header part is a rectangular board with metal contacts on its sides. These side contacts are normally made of copper and are often plated with nickel, tin or gold for increased conductivity and corrosion resistance. The pins are cylindrical metal pieces with solder lugs on one end and a flat head on the other. For proper electrical contact, the pins must be lubricated before installing them in the header.

When the header and the male pin are installed together, the solder lugs of the pins make contact with the metal contacts on the sides of the header. This creates an electrical contact between the two parts, allowing electric current to flow through the connector. The flat head on the other end of the pin holds the pin in place in the header and also prevents any unintended contact between the contacts. This ensures a reliable and durable connection between the two devices.

Conclusion

The 81020-650203 connector is one of the most widely used rectangular connectors for transmitting power, data and RF signals between two devices. It has many applications in various industries and consumer electronics. The working principle of the 81020-650203 connector involves the use of a header and male pins that are soldered together to create an electrical contact between them. This allows electric current to flow through the connector and establish a reliable and durable connection between the two devices.
