通用串行总线数据与电源接口 第1-3部分：通用组件 USB Type-C 电缆和连接器规范

[中文适用范围]： IEC 62680-1-3:2026 标准对 USB Type-C 插座、插头及线缆的规格进行了定义。USB Type-C 电缆与连接器规范的制定遵循以下原则： 1. 支持新型主机与设备的形态设计，其中尺寸、工业设计及外观风格为关键考量因素； 2. 与现有 USB 主机和设备硅基解决方案无缝兼容； 3. 提升连接 USB 设备的使用便捷性，着重减少用户对插头与线缆方向的混淆。 该规范定义了可与现有 USB 接口电气和功能规范兼容的插座、插头、线缆及检测机制，涵盖在新型平台与设备中生产及使用新型 USB 线缆/连接器解决方案所需的关键方面，同时支持与现有平台及设备的互操作性，具体包括： - USB Type-C 插座：含机电定义及性能要求； - USB Type-C 插头及线缆组件：含机电定义及性能要求； - USB Type-C 与旧有电缆组件及适配器； - 基于 USB Type-C 的设备检测与接口配置，含对旧有连接的支持； - 针对 USB Type-C 连接器优化的 USB 电源传输（USB Power Delivery）。 IEC 62680-1-3:2026 作废并取代 2024 年发布的第六版，属编辑修订。本标准为 USB-IF（USB 开发者论坛）发布的《通用串行总线 Type-C 电缆与连接器规范》第 2.4 修订版。新版发布主要整合了截至修订日期已通过的所有工程变更通知（ECN），并进行了编辑性整理与优化。 [外文原描述]： IEC 62680-1-3:2026, this specification, defines the USB Type-C® receptacles, plug and cables. The USB Type-C Cable and Connector Specification is guided by the following principles: - Enable new and exciting host and device form-factors where size, industrial design and style are important parameters - Work seamlessly with existing USB host and device silicon solutions - Enhance ease of use for connecting USB devices with a focus on minimizing user confusion for plug and cable orientation The USB Type-C Cable and Connector Specification defines a 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. IEC 62680-1-3:2026 cancels and replaces the sixth edition published in 2024 and constitutes an editorial revision. This standard is the USB-IF publication Universal Serial Bus Type-C Cable and Connector Specification Revision 2.4. New release primarily includes incorporation of all approved ECNs as of the revision date plus editorial clean-up.
