定义
A precisely machined threaded segment on a battery terminal post designed to accept nuts, bolts, or clamps for establishing and maintaining reliable electrical connections in automotive and industrial battery systems. This component ensures proper torque application, vibration resistance, and consistent electrical conductivity.
工作原理
The threaded section converts rotational force (torque) into axial clamping force when a fastener is applied, creating a secure mechanical and electrical interface. The threads provide surface area for electrical contact while maintaining pressure to prevent loosening from vibration.
材料
Lead alloys (Pb-SbPb-Ca)copper alloys (C11000C17200)or tin-plated steelselected for corrosion resistanceelectrical conductivityand mechanical strength.
Length
10-25mm
Diameter
6-10mm
Thread Type
Metric (M6, M8) or SAE (1/4-20, 5/16-18)
Thread Pitch
1.0mm, 1.25mm, or 20 TPI
Surface Finish
Smooth, free of burrs
Torque Specification
5-15 Nm
Electrical Resistance
<0.5 mΩ
标准
ISO 8854DIN 72551SAE J537

常见问题

What thread types are commonly used on battery terminal posts?

Metric threads (M6, M8) are standard in most regions, while SAE threads (1/4-20, 5/16-18) are common in North American applications.

Why is proper torque important when tightening battery terminal connections?

Correct torque ensures optimal electrical contact without damaging threads. Under-torquing causes poor connections and overheating; over-torquing strips threads or cracks terminals.

Can different battery terminal thread types be adapted?

Yes, using thread adapters or replacement terminals, but direct interchangeability requires matching thread specifications to avoid connection failures.
