1. Overview

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.

2. Main Types and Functional Classification

3. Structure and Composition

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.
