Connectors and interconnects are critical components enabling the transmission of electrical signals and power between devices. USB (Universal Serial Bus), DVI (Digital Visual Interface), and HDMI (High-Definition Multimedia Interface) connectors are standardized interfaces used for data transfer, audio/video transmission, and device charging. These technologies form the backbone of modern consumer electronics, industrial equipment, and communication systems, ensuring seamless interoperability and high-performance connectivity.
| Type | Functional Features | Application Examples |
|---|---|---|
| USB Type-A | Rectangular interface, supports data/power transmission | Computers, flash drives, peripherals |
| USB Type-C | Reversible design, supports USB 3.2/Thunderbolt 4 protocols | Smartphones, laptops, docking stations |
| DVI-D | Digital-only signal transmission | Computer monitors, projectors |
| HDMI Type A | 19-pin configuration, supports 4K@60Hz | Televisions, gaming consoles |
| HDMI Type E | Automotive-specific connectors with locking mechanism | In-vehicle infotainment systems |
Typical connectors consist of:
- Contact points (phosphor bronze with gold-plated surface)
- Insulation housing (high-temperature resistant thermoplastic)
- Shielding layers (braided copper/aluminum foil)
- Mechanical components (latches, spring contacts)
Technical composition includes signal transmission pins, power delivery channels, and EMI shielding structures to ensure signal integrity at high frequencies.
| Parameter | Description | Importance |
|---|---|---|
| Transfer Rate | Up to 40Gbps (USB4/HDMI 2.1) | Determines data throughput capacity |
| Max Resolution | 8K@60Hz (HDMI 2.1) | Supports high-definition visual output |
| Power Delivery | 100W (USB Type-C PD 3.0) | Enables device charging and powering |
