电气和电子设备用连接器.产品要求.第3-124部分:矩形连接器.频率高达500MHz的输入/输出和数据传输用10路屏蔽自由和固定连接器详细规范

[中文适用范围]： IEC 61076的这一部分涵盖了频率高达500 MHz的数据传输的10路@屏蔽@自由和固定矩形连接器，并分别规定了常见尺寸@机械@电气和传输特性和环境要求以及测试规范。本文档中涵盖的连接器提供三种编码，鉴于其不同的预期用途，这些编码仅极化键和键槽@的位置不同： A 型和 C 型连接器适用于 10/100 Mbit/s 以及 1/ 2@5 / 5 /10 Gbit/s 以太网通信。 ？ B 型连接器适用于所有其他非以太网应用，例如 signalling@ 串行或其他工业总线通信系统。 A编码：用作极化键和键槽系统的45°ut角位于公固定连接器的左下角（从配合面看）（图5a@5b）。 B 编码：45°ut 角位于公固定连接器的左上角（图 5c@5d）。 C编码：有两个45角，位于左上角和左下角（图5e@5f）。在本文档中，三种编码@ A@ B@ 和C 被指定为??A 型??@ ??B 型??和??C型 [外文原描述]： IEC 61076-3-124:2019 covers 10-way, shielded, free and fixed rectangular connectors for data transmission with frequencies up to 500 MHz and specifies the common dimensions, mechanical, electrical and transmission characteristics and environmental requirements as well as test specifications respectively. Connectors covered in this document are provided in three codings that differ only for the position of the polarization key and keyway, in view of their differently intended use: Connectors type A and C are intended for 10/100 Mbit/s as well as for 1/ 2,5 / 5 /10 Gbit/s Ethernet communication. Connectors type B are intended for all other non-Ethernet applications such as signalling, serial or other industrial bus communication systems. - A-coding: The 45° cut corner used as polarization key and keyway system is located on the lower left corner of the male fixed connector (viewed from mating face) (Figures 5a, 5b). - B-coding: The 45° cut corner is located on the upper left corner of the male fixed connector (Figures 5c, 5d). - C-coding: There are two 45° corners located at the upper left and lower left corner (Figures 5e, 5f). - In this document, the three codings, A, B, and C are designated as “Type A”, “Type B” and “Type C”. Key words: Rectangular Connectors, 10 Way Shielded, Free and Fixed Connectors, I/O and Data Transmission, Frequencies up to 500 MHz The contents of the corrigendum of March 2020 have been included in this copy.
