Rectangular Connectors - Housings are one of the most common and versatile types of connectors used for various applications. FI-R21H is an example of this type of connector. This connector is designed to provide secure connection between an external component and an internal component such as a motherboard. It provides both mechanical and electrical connection reliability and offers a cost-effective solution for a variety of applications.

Overview

FI-R21H is a three-pin, right angle, female housing connector produced by Fujikura, which specially designed for use in electronic equipment. It is made of a high-temperature thermoplastic material that ensures both electrical and mechanical connection. The connector is compliant to UL77 and CSA22.2 standards and is a UL/CSA certified product. Its operating temperature range is between -40°C to +105°C, and the rated voltage is 300V AC.

Connection Characteristics

The FI-R21H is equipped with three pins, which are arranged to ensure the connection of two components in the horizontal and vertical directions. The pins are made of phoshpor-bronze material with a thickness of 0.2mm which is highly resistant to vibration and corrosion. Furthermore, the contact resistance is a low 0.05Ω or less. The insulation resistance is 1,000MΩ or more, and is expected to remain good even after many applications. The mechanical strength between the pins is 3A for a single pin, and 10A for two or more pins.

Mounting

The FI-R21H is mounted on a clean flat surface using all kinds of mounting methods. These include direct mounting onto the PCB and mounting onto a flat surface using a through-hole mount. The contact is held in place during processing by means of a retainer bar. For better rigidity, the connector can also be mounted to the PCB using an epoxy top holder or a soldered top holder.

Applications

FI-R21H can be used in a wide variety of applications including automotive, industrial, consumer and medical. It is widely used in small electronics such as mobile phones, tablets, PDAs, game consoles, wearable devices and computer peripherals. FI-R21H is suitable for applications where smaller size, improved sound quality, low insertion and extraction force are required. Other applications of the connector include power supply; mobile telecommunications; military; computer gaming; data communication systems; instrumentation; home entertainment systems; storage arrays and printers.

Working Principle

The FI-R21H connector works on the principle of electrical and direct connection between the two components. The electrical connectiveness is enabled by the gold-plated contact pins which are designed to provide viable, secure, and high-performance electrical contact. This ensures that the electricity flows in the desired direction without any impedance or interference. The direct connection between the components is made possible by the two components configuration which provides the necessary mechanical support and alignment. This makes the connection secure and durable, eliminating the need for any additional connections or fixtures.

Conclusion

The FI-R21H is a great example of a rectangular connector that can be used in a variety of applications. It is a cost-effective solution for those who wish to save money while still ensuring that the connection is secure and of good quality. The connector is UL/CSA certified and ensures electrical and mechanical contact with reliable contact resistance and low insertion and extraction force. It is best suited for applications where smaller size and good sound are required. In conclusion, FI-R21H is a great connector for a variety of applications.
