USB, DVI, HDMI Connectors
1. What are USB, DVI, HDMI Connectors?
USB, DVI, and HDMI connectors are mainly used for signal transmission and power supply between computers and audio and video devices, with diverse interface forms and technical standards. They interconnect devices through physical ports, and characteristic parameters include connector type, number of contacts, male and female end design, installation method, rated current/voltage, etc.
2. What are the Types and Technical Characteristics of USB, DVI, HDMI Connectors?
1) USB Connector
Interface Type
Type-A: 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.
Type-B: Square interface, commonly used in devices such as printers, providing stable data transmission.
Type-C: Symmetrical design, supports forward and reverse plugging, integrated USB4 standard (40 Gbps), and PD fast charging protocol.
Micro/Small Interface: such as Micro-USB, used in mobile devices.
2) DVI Connector
Version Type
DVI-A: Transmits only analog signals and is compatible with VGA devices.
DVI-D: Pure digital signal transmission, supports 1920×1200@60Hz resolution.
DVI-I: Compatible with analog and digital signals, suitable for multiple scenarios.
Limitations: Does not support audio transmission, gradually replaced by HDMI/DP interface.
3) HDMI Connector
Mainstream Specifications
HDMI 2.0: Supports 4K@60Hz and HDR.
HDMI 2.1: Bandwidth increased to 48 Gbps, supports 8K@60Hz and 4K@120Hz high refresh rates.
Interface Form: includes standard HDMI, Mini-HDMI, and Micro-HDMI, adapting to different device sizes.
Advantages: Synchronous transmission of audio and video signals, simplifying wiring complexity.
3. What are the Hardware Design Features of USB, DVI, HDMI Connectors?
Male and Female End Distinction: 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.
Structural Parameters: Including shielding layer design (such as HDMI copper foil shielding), terminal gold plating process (improving corrosion resistance), etc.
Installation Method: including various types such as onboard welding, panel fixing, and direct cable connection.

PARTS, BOM OR COMPLETE PCBA
Request your component or BOM quote.
Tell us whether you need parts only or a finished PCB assembly. Availability, price, order quantity and delivery are confirmed for your specific request.
- Exact manufacturer part numbers and manufacturers
- Required quantity, target date and shipping destination
- BOM file and quantity per board for a complete build
- Approved alternatives and any parts that must not be substituted
- For turnkey PCBA: PCB files, placement data and test requirements
Proposed substitutions need your approval. Tell us about traceability, documentation or packaging requirements before purchasing is agreed.
Files are optional for an initial discussion. You can send the BOM by email if the uploader does not accept your file. An inquiry does not authorize purchasing or production.
Start with your requirements.
Email is required. Add “components only” or “full turnkey PCBA” in the service field.
