Why terminal selection matters

Fuse box and relay box terminals carry power paths. Poor fit, plating, material thickness or crimp quality can create heat and reliability risk.

Main technical checks

Review current rating, wire range, terminal material, plating, crimp wing geometry, insertion force and matching housing design.

RFQ preparation

Provide drawing, mating part, wire size, current load, sample photo, plating requirement and monthly or annual usage.

FAQ

Common questions

Common procurement and engineering questions related to this topic.

What is the key risk in fuse box terminal selection?

Current overload, poor mating force, weak crimping and wrong plating can create heat and long-term reliability problems.

Can terminal drawings be reviewed before quotation?

Yes. Terminal drawings help confirm material, plating, wire range, crimp shape and matching connector housing.
