What are the Types and Technical Characteristics of USB, DVI, HDMI Connectors? </h2> <h3> 1) USB Connector </h3> <p> Interface Type </p> <p> <strong>Type-A</strong>: Standard rectangular interface, widely used in computers, chargers, and other devices, supports USB 1.1 to 3.2 standards, and the transmission rate is increased from 12 Mbps to 20 Gbps. </p> <p> <strong>Type-B</strong>: Square interface, commonly used in devices such as printers, providing stable data transmission. </p> <p> <strong>Type-C</strong>: Symmetrical design, supports forward and reverse plugging, integrated USB4 standard (40 Gbps), and PD fast charging protocol. </p> <p> <strong>Micro/Small Interface</strong>: such as Micro-USB, used in mobile devices. </p> <p> </p> <h3> 2) DVI Connector </h3> <p> Version Type </p> <p> <strong>DVI-A</strong>: Transmits only analog signals and is compatible with VGA devices. </p> <p> <strong>DVI-D</strong>: Pure digital signal transmission, supports 1920×1200@60Hz resolution. </p> <p> <strong>DVI-I</strong>: Compatible with analog and digital signals, suitable for multiple scenarios. </p> <p> <strong>Limitations</strong>: Does not support audio transmission, gradually replaced by HDMI/DP interface. </p> <p> </p> <h3> 3) HDMI Connector </h3> <p> Mainstream Specifications </p> <p> <strong>HDMI 2.0</strong>: Supports 4K@60Hz and HDR. </p> <p> <strong>HDMI 2.1</strong>: Bandwidth increased to 48 Gbps, supports 8K@60Hz and 4K@120Hz high refresh rates. </p> <p> <strong>Interface Form</strong>: includes standard HDMI, Mini-HDMI, and Micro-HDMI, adapting to different device sizes. </p> <p> <strong>Advantages</strong>: Synchronous transmission of audio and video signals, simplifying wiring complexity. </p> <p> </p> <h2> 3. What are the Hardware Design Features of USB, DVI, HDMI Connectors? </h2> <p> <strong>Male and Female End Distinction</strong>: The male end is a raised needle design, and the female end is a groove hole design to ensure the safety of unidirectional current transmission. </p> <p> <strong>Structural Parameters</strong>: Including shielding layer design (such as HDMI copper foil shielding), terminal gold plating process (improving corrosion resistance), etc. </p> <p> <strong>Installation Method</strong>: including various types such as onboard welding, panel fixing, and direct cable connection. </p> <p> </p> <h2> 4.
