定义
A precision-machined metal component designed to provide a stable mounting platform and electrical interface for battery terminal posts in automotive electrical systems. It ensures proper alignment, mechanical stability, and reliable current transfer between the battery and vehicle wiring harness.
工作原理
The base flange functions as both a mechanical anchor and electrical conductor. It distributes clamping force evenly across the battery terminal post, prevents rotation or displacement during vibration, and provides a low-resistance path for electrical current through direct metal-to-metal contact with the terminal post and connecting cables.
材料
Lead-coated copper alloy (C11000 or equivalent)aluminum alloy 6061-T6or brass C36000 for corrosion resistance and optimal conductivity. Surface finish: Electroplated tin or nickel coating (5-10μm thickness) for enhanced corrosion protection.
Weight
Approximately 120g
Thickness
8mm ±0.2mm
Inner Diameter
12.7mm (0.5 inch)
Mounting Holes
4x M6 threaded
Outer Diameter
45mm ±0.5mm
Temperature Range
-40°C to +125°C
Bolt Circle Diameter
35mm
Torque Specification
8-10 Nm for terminal post connection
Electrical Resistance
<0.5mΩ
标准
ISO 8820-8DIN 72551SAE J537

常见问题

What is the primary function of a base flange in battery terminal applications?

The base flange provides mechanical stability to prevent terminal post rotation or loosening due to vibration, while ensuring consistent electrical contact between the battery post and connecting cables.

Can base flanges be used with different battery terminal sizes?

Base flanges are typically designed for specific terminal post diameters (commonly 12.7mm/0.5" or 16mm/0.625"). Using incorrect sizes can compromise both mechanical security and electrical performance.

How does material selection affect base flange performance?

Copper alloys offer superior conductivity but require corrosion-resistant coatings. Aluminum provides good conductivity with lighter weight. Material choice balances conductivity, corrosion resistance, mechanical strength, and cost requirements.
