IEC 62680-1-3:2021定义了USB类型C™ 插座、插头和电缆。 USB Type-C电缆和连接器规范定义了与现有USB接口电气和功能规范兼容的新插座、插头、电缆和检测机构。本规范涵盖了在较新的平台和设备中生产和使用此新USB电缆/连接器解决方案以及与现有平台和设备互操作所需的以下方面: -USB C型插座，包括机电定义和性能要求 -USB C型插头和电缆组件，包括机电定义和性能要求 -USB C型至传统电缆组件和适配器 -基于USB Type-C的设备检测和接口配置，包括对传统连接的支持 -USB电源传输针对USB Type-C连接器进行了优化。 本规范旨在作为现有USB 2.0、USB 3.1和USB电源传输规范的补充。它仅涉及实现和支持USB C型插座、插头和电缆所需的元件。 提供规范性信息，以实现按照本规范设计的组件的互操作性。提供的信息可以说明可能的设计实现。 IEC 62680-1-3:2021取消并取代了2018年发布的第三版，并构成技术修订版。 新版本主要用于通过USB C型连接器和电缆启用USB4。还包括自修订之日起纳入所有批准的ECN以及编辑清理。

IEC 62680-1-3:2021 defines the USB Type-C™ receptacles, plug and cables. The USB Type-C Cable and Connector Specification defines a new receptacle, plug, cable and detection mechanisms that are compatible with existing USB interface electrical and functional specifications. This specification covers the following aspects that are needed to produce and use this new USB cable/connector solution in newer platforms and devices, and that interoperate with existing platforms and devices: - USB Type-C receptacles, including electro-mechanical definition and performance requirements - USB Type-C plugs and cable assemblies, including electro-mechanical definition and performance requirements - USB Type-C to legacy cable assemblies and adapters - USB Type-C-based device detection and interface configuration, including support for legacy connections - USB Power Delivery optimized for the USB Type-C connector. This specification is intended as a supplement to the existing USB 2.0, USB 3.1 and USB Power Delivery specifications. It addresses only the elements required to implement and support the USB Type-C receptacles, plugs and cables. Normative information is provided to allow interoperability of components designed to this specification. Informative information, when provided, may illustrate possible design implementations. IEC 62680-1-3:2021 cancels and replaces the third edition published in 2018 and constitutes a technical revision. New release primarily for enabling USB4 over USB Type-C connectors and cables. Also includes incorporation of all approved ECNs as of the revision date plus editorial clean-up.
