1.1 Overview Electronic Connectors, also known as "connectors" or "adjacent junctions", are widely used in various electronic devices, such as household appliances, communication equipment, computers, etc. In recent years, with the accelerated development of optoelectronic technology, the use of connectors in high-speed broadband networks and optical fields (such as fiber optics) has been increasing. This article aims to briefly explain the basic theory of connectors and provide a detailed explanation of their common types and main application scenarios.
1.2 Basic knowledge The working principle of connectors mainly utilizes the contact resistance between contacts to conduct electricity. Its main function is to transport current or signals by connecting two active devices. Regardless of the circuit form or device function, we can always find the presence of connectors. In addition, connectors can also flexibly apply various materials to make contacts, such as metal (gold, silver, copper), plastic, plug-in, and so on.
1.3 Types and Characteristics According to different connection methods, connectors are usually divided into the following seven types: A. Circular/rectangular shape This type of connector is suitable for quick insertion and removal operations and has a wide range of applications. B. Narrow interface type Due to the need to insert into narrow spaces, this type of connector is mainly suitable for mobile devices, small devices, etc. C. SATA type This type of connector is applied in the field of data transmission and has the advantages of high speed and precision. D. Power Connector type This type of connector is designed specifically for high-power power ports and has good corrosion resistance. E. Ethernet Connector type Ethernet interface type, suitable for various LAN and WAN connections, with good anti-interference ability. F. Bluetooth connector Supports connecting multiple devices, such as mobile phones, tablets, etc. Goog Fi connector is also one of them. This type of connector is suitable for high-speed Internet services.
1.4 Application examples To some extent, connectors are not limited to current, but are also used in optical signal pathways. For example, the lighting equipment and hard drives in sports fields have their own unique connectors, while the connectors required for launching rockets are completely different. Most connectors have their own specific functions, with various shapes, sizes, and classification methods, such as transmission medium, frequency, purpose, shape, etc. At the same time, with the continuous progress of technology, new types of connectors and application scenarios have emerged one after another, such as connectors used to connect lighting controls and connectors for scrolling LED display, which have obvious differences.
1.5 Summary In summary, as an important component in electronic devices, the rational selection and use of connectors are crucial for ensuring device performance.
In the future, with the continuous emergence of new materials and technologies, the connector market will have a broader development prospect.
