电气和电子设备用连接器.产品要求.第2-012部分:圆形连接器.根据IEC 61076-2-101 IEC 61076-2-109 IEC 61076-2

[中文适用范围]： 本文档规定了具有内推拉开锁机制的圆形连接器，其尺寸源自兼容M12螺纹锁紧连接器的尺寸，并符合IEC 61076-2-101、IEC 61076-2-109、IEC 61076-2-111和IEC 61076-2-113规定的配合界面。根据本文件，具有内推拉开锁机制的母型固定连接器可与相应编码的、具有M12螺纹锁紧机制的公型自由连接器配合。本文件涵盖：a) 额定电流最高至16 A、额定电压最高至630 V的电源连接器，通常用于工业场所电气设备的供电；b) 传输频率高达500 MHz的数据和信号传输连接器。这些连接器由固定连接器和自由连接器组成，两者均可重接或不可重接，并采用上述内推拉开锁机制。公型连接器具有从Ø0.6 mm到Ø1.5 mm的圆形接触件。本文件涵盖了各种具有不同接触件排列且互不兼容的“编码”类型的连接器。内推拉开锁机制的设计可防止公型内推拉开锁自由连接器与母型M12螺纹锁紧连接器（即使编码相同）意外配合。本文件涵盖的某些具有母型接触件的自由连接器型号配备了内推和外推双重锁紧功能，以便也可与根据IEC 61076-2-010的相应编码的公型固定或自由连接器配合。 [外文原描述]： IEC 61076-2-012:2020 specifies circular connectors with an inner push‑pull locking mechanism of a size derived from and thus being compatible with M12 screw‑locking connectors and with mating interfaces according to IEC 61076‑2‑101, IEC 61076‑2‑109, IEC 61076‑2‑111 and IEC 61076‑2‑113. A female fixed connector with inner push-pull locking according to this document is intermateable with a correspondingly coded male free connector with M12 screw-locking according to IEC 61076-2-101, IEC 61076-2-109, IEC 61076-2-111 or IEC 61076-2-113. This document covers both: a) power connectors with current ratings up to 16 A and voltage ratings up to 630 V, typically used for power supply of electrical equipment used in industrial premises, and b) connectors for data and signal transmission with frequencies up to 500 MHz. These connectors consist of both fixed and free connectors, either rewirable or non‑rewirable, with M12 inner push‑pull locking as explained above. Male connectors have round contacts from Ø0,6 mm up to Ø1,5 mm. This document covers various types of connectors identified by their "codings" with different contact arrangement, not mutually interchangeable. The design of the inner push‑pull mechanism prevents the unintended mating of the male inner push‑pull free connector with the female connector with M12 screw‑locking even for identical coding. Some styles of free connectors with female contacts covered in this document are equipped with both inner and outer push-pull locking for intermateability also with correspondingly coded male fixed or free connectors according to IEC 61076-2-010.
