Modular Connectors

Modular Connectors are a type of highly standardized, flexibly configurable interconnection device in electronic engineering, which is widely used in data transmission, signal processing, power supply, and other fields. Its core feature is to achieve multifunctional integration and high-density layout through modular design.

 

1. What are the Core Features of Modular Connectors?

1) ‌Structure and Design Flexibility‌

Adopting a modular combination, it supports the integration of different transmission types (such as power, signal, data) in the same connector, significantly saving installation space and improving system integration.

 

Physical dimensions are standardized, and common specifications include 10mm×10mm, 15mm×15mm, etc. At the same time, the number and arrangement of pins can be customized according to needs.

 

2) ‌Performance Requirements‌

Mechanical Performance‌: Focus on plug-in and pull-out force (the standard needs to be moderate to ensure reliability), mechanical life (number of plug-in and pull-out times), and contact retention (to prevent the terminal from falling off).

 

‌Electrical Performance‌: Emphasize low contact resistance (milliohm level) and insulation resistance (typical value is above 100MΩ), support high-frequency signal transmission (such as Cat.6A standard) and high current load (such as 1.5A/125V).

‌Environmental Adaptability‌: It must meet the temperature range (-20°C to 70°C) and vibration and corrosion resistance requirements.

 

3) ‌Manufacturing and Assembly Optimization‌

Modular design supports automation and high-speed manufacturing, reducing manual errors. For example, the floating design can compensate for PCB mounting errors and reduce the impact of lateral loads on connectors.

 

Optimization of contact materials and shell materials (such as phosphor bronze contacts, PBT plastic shells) improves durability and signal stability.

 

2. What are the Types of Modular Connectors?‌

‌Board-side Connector‌: It is used for interconnection between circuit boards and supports SMT or DIP installation methods. It is commonly used in computers and industrial control equipment.

‌High-frequency Connector‌: Such as SMA, BNC, etc., suitable for RF signals and high-speed data transmission scenarios (such as communication base stations, measuring instruments).

‌Multi-functional Integrated Connector‌: Such as Han-Modular domino module, which can integrate power, data, and pneumatic interfaces at the same time, and is used in complex systems such as packaging equipment and injection molding machinery.

 

3. What are Modular Connectors Used for?‌

‌Industrial Control‌: HARTING brand Han-Modular Domino modules support Cat.6A data transmission standards and are used in conveyor systems and control cabinets.

‌Communication Equipment‌: For example, RJ45 modular connectors (8P8C design) are used for Ethernet interfaces and meet the UL 94 V-0 flame retardant rating.

 

4. Standardization and Specifications of Modular Connectors

‌Interface Definition‌: Clearly define pin layout, electrical characteristics, and signal transmission protocols (such as the MCIO standard defines pin isolation for data transmission and power distribution).

‌Environmental Certification‌: Mainstream products comply with the RoHS directive and use lead-free soldering processes.

‌Industry Compatibility‌: Some connectors are compatible with DIN standards to ensure interoperability with existing equipment.
