Barrel - Power Connectors: L722RAS Application Field and Working Principle

Barrel power connectors are designed for the reliable power supply of electronic equipment. They provide an efficient, cost-effective method of connecting power to electronic devices that require high voltage and amperage. Barrel power connectors have been in widespread use since the 1970s, and more recently the L722RAS connector has been developed as a standardized alternative, providing many advantages over typical connectors.

Features of The L722RAS Connector

The L722RAS power connector is a variation of the standard barrel connector. It features a 2-prong design that is ideally suited for connecting laptops, desktop PCs, and other computer devices that require plug-in power adapters. It has a maximum current carrying capacity of 4 Amps, and is typically rated for up to 10 Amps. It also features stainless steel connector contacts that resist corrosion, as well as contact retention clips and strain relief for added physical security and reliability.

The L722RAS power connector is rated for up to 250 Volts AC, and is also UL listed for safety. Its body is made from nickel plated brass, and it is constructed to withstand short-term voltage surges. Additionally, each connection point includes a thermoplastic insulating shell to prevent the risk of shorts when connecting multiple power sources.

Advantages of The L722RAS Connector

The two-prong design of the L722RAS power connector makes it easier to connect and disconnect than other barrel style connectors. It is also resistant to vibration and shocks, making it suitable for use in more extreme applications. Additionally, its resistance to corrosion, contact retention clips, and strain-relief features provide increased reliability. Furthermore, its nickel and brass construction, thermoplastic insulation, and UL ratings ensure safety and durability.

Application Fields of The L722RAS Connector

The L722RAS power connector is primarily used for computer power applications. It is one of the most commonly-used connectors for plugging in laptop and desktop PCs, as well as various other computer-related devices. It is also used in more specialized applications such as industrial and commercial testing and measurements, and in medical and scientific equipment.

Working Principle of The L722RAS Connector

The basic working principle of the L722RAS power connector is that when the two metal prongs of the connector come into contact with an AC power source, they form a closed electrical circuit, allowing the current to flow. The amount of current that can pass through the connector is determined by the size and construction of the connector, as well as the power source itself.

The L722RAS connector has two insulated contacts to prevent the risk of shorting out the power source. When the connector is plugged into a power source, these contacts are inserted into the power socket and come into contact with the metal conductors inside. This ensures that the power source is not shorted out, and is protected from any kind of electrical surge.

The L722RAS connector also has two retention clips on the outside of the connector. These clips fit over the power socket, providing additional physical security and resistance to vibrations. Together, these features ensure reliable, long-term performance of the L722RAS connector.

Conclusion

The L722RAS power connector is a highly reliable and safe device for connecting computers and other electronic equipment to a power source. It is especially suited for applications that require higher current carrying capabilities, as well as increased protection against electrical surges and physical shocks and vibrations. Its two-prong design makes it easy to use, and its thermoplastic insulation ensures added safety. Its two contact retention clips also provide additional security and stability. This makes the L722RAS power connector an ideal choice for a variety of power connection requirements.
