082-91 Connectors: Application Field and Working Principle

Introduction

082-91 connectors, also known as the APC-7 (American Physical Connector) or U.FL (ultra-low profile) connector, are an extremely tiny type of coaxial connectors used in many portable electronic devices, such as laptops, tablets, cellular phones and portable radios. Due to their extremely small size and easy assembly, they are typically used for wireless application and in systems where weight and space are at a premium. These connectors are available in several forms, including a right angle type and a straight type.

Application Fields of 082-91 Connectors

One of the main applications for the 082-91 connectors is high-frequency wireless communication. This type of connection can provide to the device the ability to connect to wireless networks and easily transmit data back and forth over the wireless network. This makes them a great choice for laptops, tablets, and other portable devices. Another application for these connectors is in audio systems. These small and lightweight connections are perfect for connecting portable media players, such as iPods, to portable speakers, televisions, and home theater systems. These connections are also ideal for connecting audio components, such as microphones, headphones, and subwoofers, in professional audio systems.

Working Principle of 082-91 Connectors

082-91 connectors, as with all coaxial connectors, employ a central insulated pin called the center conductor and a circular shield surrounding it called the outer conductor. The center conductor transfers the electrical signal while the outer conductor works to shield the center conductor from electromagnetic interference, or EMI, that is common in wirelessly transmitted signals. Both the center conductor and the outer conductor are typically made of copper or copper alloy although some versions may use aluminum or stainless steel.The signal is typically transferred through the center conductor to the outer shell which is then connected to ground. This effectively shields the signal from electromagnetic interference and allows for a more reliable transmission of data. The connector is designed so that the center pin and the outer shell are not in contact until they are properly inserted into the mating connector. This provides an electrical connection that will not produce any EMI and ensures a reliable connection.

Conclusion

082-91 connectors are an extremely small and lightweight type of connector that is perfect for use in portable electronic devices. Due to their small size and easy assembly, these connectors are popular for use in wireless applications, providing the device with the ability to easily connect to wireless networks and transmit data back and forth. They are also ideal for use in audio applications where lightweight and small connectors are needed. These connectors are designed with a central insulated pin that transfers the electrical signal and a circular shield that protects the signal from EMI. This provides a reliable connection in which the signal will be shielded against electromagnetic interference.
