电子设备用连接器 第4-101部分：质量保证印刷板用连接器 印刷板和背板用基本间距为2 0 mm 的两部分连接器模块 的特殊规范

[中文适用范围]： 本部分IEC 61076涵盖了用于工业环境的混合矩形连接器，其电源部分为3极16A，数据部分为 duplex（双工）LC型光纤连接器。这些连接器包括固定连接器和自由连接器，均可为可重插拔式或不可重插拔式（两部分均适用），并采用IEC 61076-3-117中描述的带IP65/IP67防护等级的推入式拉出式外壳，适用于恶劣应用环境。此类外壳的配合尺寸允许满足IEC 61753-1-3中关于光纤部分连接器的性能等级I类要求，唯一例外是工作温度范围为-25°C至+70°C。电部分可能具有不同的额定绝缘电压。雄性连接器具有3个电圆形接触点，直径为1.6毫米，额定电流为16安培。光纤部分通过使用IEC 61754-20中定义的所有LC型双工光纤连接器变体的通用配合配置来提供数据传输，涵盖 therein 规定的专用光纤类型和光纤端接技术。本文件提供的不同编码方式防止了相应编码的雄性或雌性连接器与其他同样尺寸且符合其他标准的接口配合，以及本文件提供的不同编码方式之间的交叉配合。 [外文原描述]： IEC 61076-3-123:2019. covers hybrid rectangular connectors with a 3 poles 16 A electric portion for power supply and a duplex fibre optic connector type LC portion for data transmission. These connectors consist of fixed and free connectors, either rewirable or non-rewirable (for both portions) and use the rectangular push-pull housing described in IEC 61076-3-117 with IP65/IP67 degree of protection, for harsh applications. The mating dimensions of such housings allow fulfilling the performance class Category I according to IEC 61753-1-3 in regards to the fibre optic portion of the connector with the exception of the operating temperature range which is –25 °C/+70 °C. The electric portion may have different rated insulation voltages. Male connectors have 3 electric round contacts Ø1,6 mm, with 16 A rated current. The fibre optic portion provides data transmission by using the common mating configurations for all variants of the type LC duplex fibre optic connectors as defined in IEC 61754-20, for dedicated fibre types and fibre termination technology covered therein. The different codings provided by this document prevent the mating of accordingly coded male or female connectors to any other similarly sized interfaces covered by other standards and the cross-mating between the different codings provided by this document. Key words: Rectangular Connectors, Hybrid Connectors, Power Supply and Fiber Optic Data Transmission.
