Detailed Explanation Of The Technical Specifications For The Selection Of Heavy-duty Connector Design Materials!

In the design of electronic heavy duty 12 volt connectors, material selection directly affects the electrical performance, mechanical life and environmental adaptability of 12v heavy duty connector. Pin header and mother header heavy duty crimp connectors are very commonly used electronic heavy duty waterproof electrical connectors products. In this article, Xinpengbo Electronics will analyze the decision-making ideas of pin header and mother header material selection technology for everyone.

The technical specifications for the selection of pin header and mother header materials are as follows

1. Pin header and mother header conductor material performance matrix:

Copper alloy system:

Brass (H62): obvious cost advantage, suitable for conventional connection of consumer electronics (conductivity 30% IACS)

Phosphor bronze (C5191): elastic modulus 110GPa, plug life of more than 5000 times

Beryllium copper (C17200): yield strength ≥1000MPa, the first choice for military-grade high-frequency connection

Special material application

Stainless steel (SUS304): salt spray test over 1000 hours, mandatory standard for marine equipment

Composite coating: gold plating (0.8μm) + nickel bottom layer, contact resistance ≤5mΩ
