IEC 61076-4-110:2001

Overview

IEC 61076-4-110:2001 is an international standard published by the International Electrotechnical Commission (IEC) that specifies requirements for printed board connectors with assessed quality. This standard focuses on latched cable connector systems with a 2.0 mm basic grid, incorporating full shielding and a robust latching function. As part of the IEC 61076 series, this standard supports dependable electronic equipment interconnection by defining design, performance, and quality criteria for these connectors. It also carries the identifier QC 480301XX0011 within the IEC Quality Assessment System for Electronic Components (IECQ).

Key Topics

• Connector Systems: Defines latched cable connectors designed for use with printed circuit boards (PCBs) and backplanes.
• 2.0 mm Grid: Standardizes connectors based on a 2.0 mm pitch, supporting compact, high-density electronic assemblies.
• Full Shielding: Specifies requirements for electromagnetic compatibility (EMC) through comprehensive connector shielding.
• Latching Function: Ensures secure mechanical retention even in environments prone to vibration, shock, or movement.
• Assessed Quality: Outlines procedures for quality assessment, including approval testing, periodic inspection, and lot-by-lot controls.
• Mounting and Styles: Recommends mounting methods and defines multiple styles and variations for cable and board connectors.
• Mechanical and Electrical Characteristics: Details on mechanical robustness, engaging/separating forces, retention forces, and electrical parameters like insulation resistance and current-carrying capacity.
• Testing and Inspection: Includes comprehensive schedules for type approval, conformance testing, and performance validation.

Applications

IEC 61076-4-110 is essential in environments that require reliable, high-density, and shielded board-to-cable connections. Key practical applications include:

• Industrial Automation: Secure connection solutions for control systems and industrial electronic equipment.
• Telecommunications: Used in network hardware, routers, and switching devices where signal integrity and EMC are crucial.
• Data Centers and Computing: Applied in server racks, storage devices, and backplane systems, ensuring robust and maintainable connections.
• Transportation Electronics: Suitable for railway, automotive, and avionics electronics which demand secure latching and resistance to vibration.
• Consumer Electronics: Integrated in complex devices where space-saving and secure, shielded connections are required.

The full shielding and latching capabilities specified in IEC 61076-4-110 help minimize signal interference, ensure reliable contact, and prevent accidental disconnection, bringing significant value across industries that require high quality and dependable electronic connections.
