Contacts/Terminals: Temperature Range -40°C to +125°C

Q: What is the difference between contacts and terminals?

Contacts refer to the conductive elements within connectors that mate with counterparts, while terminals are the end pieces crimped onto wires that insert into connectors to contact these elements.

Q: How are terminals typically attached to wires?

Terminals are primarily attached using crimping tools that deform the terminal barrel around the wire conductor and insulation, creating a gas-tight, mechanically secure, and electrically reliable connection.

Q: What plating is best for automotive terminals?

Tin plating is common for cost-effective applications, while silver or gold plating is used for high-reliability connections requiring superior corrosion resistance and lower contact resistance.

Component Specifications

Definition

Contacts and terminals are precision-engineered conductive components designed to establish reliable electrical connections between wires and connectors in automotive wiring harness systems. They ensure consistent signal transmission, power delivery, and grounding while withstanding vibration, temperature fluctuations, and environmental exposure.

Working Principle

Contacts and terminals function by creating a low-resistance electrical path through mechanical pressure or crimping between conductive surfaces. The terminal's design ensures proper insertion into connector housings, maintaining contact force through spring tension or interference fit to prevent disconnection under operational stresses.

Materials

Copper alloys (C11000, C26000), brass, phosphor bronze, or beryllium copper with tin, silver, or gold plating for corrosion resistance and conductivity enhancement.
