U-Shaped Spring Cold-Pressed Terminal Wire SW-N-17 — Low-Resistance Crimp for New Energy & Automotive

SW-N-17 Terminal Wire — High-Current Connections Fail at the Crimp, Not the Cable

In new energy battery packs, EV power distribution and vehicle electrical systems, the cable almost never fails — the crimp does. A poorly formed terminal creates contact resistance, resistance makes heat, heat loosens the joint, and the cycle ends in a scorched lug or a dropped load. The Snowwolf SW-N-17 is engineered at exactly that interface: a U-shaped spring cold-pressed terminal wire built for new energy, automotive and general electrical assemblies.

Cold-pressing (cold crimping) compresses conductor and terminal into a gas-tight joint — no solder, no heat-affected zone, no flux residue. The U-shaped / spring-ring terminal geometry holds contact pressure under constant vibration, which is what battery-pack service, engine-mounted wiring and mobile equipment dish out every day. One honest note before you order: cold-press quality depends on matching the terminal to your wire gauge and stud size — tell us your cable cross-section, stud diameter and current requirement and we will confirm the tooling and the terminal spec before production. Wire length, gauge and terminal dimensions are customizable

The SW-N-17 is produced in our ISO/TS 16949-certified factory in Dongguan with ROHS & YACE-003-compliant material sourcing and a 1-year warranty. Orders start at 100 pieces at $5.50/piece FOB Shenzhen, with 15–25 day delivery, L/C or T/T payment and private labeling available. Send us your wire gauge, stud size and application — quotations return within 24 hours.

Key Advantages

✔ Gas-Tight Cold-Press Joint:​ Cold-pressed crimping fuses conductor and terminal into a low-resistance, gas-tight connection — no solder, no heat-affected zone.
✔ U-Shape Holds Contact Pressure:​ U-shaped / spring-ring geometry keeps the contact stable under continuous vibration in EV and engine-mounted duty.
✔ Resistance You Can Measure:​ Precision cold crimping minimizes contact-point resistance, reducing heat build-up in high-current new energy circuits.
✔ Built for Harsh Duty:​ The spring-ring terminal variant is rated for vibration-heavy battery pack, vehicle and mobile equipment environments.
✔ Made-to-Fit Terminals:​ Wire length, wire gauge and terminal dimensions customized to your drawing or sample — OEM/ODM supported.
✔ Wholesale-Ready:​ MOQ 100 pcs at $5.50/pc, 15–25 day delivery, L/C or T/T, private label supported.

FAQ

Q1: What should I send to get a correct quote?​
Wire cross-section (mm² or AWG), stud diameter, wire length and current requirement. We match the terminal and the crimping die before production.

Q2: Why cold-pressed rather than soldered?​
Cold-press forms a gas-tight joint with no heat-affected zone or flux residue — more consistent and more reliable in vibrating, high-current duty.

Q3: Can I get custom terminal sizes for my pack design?​
Yes — terminal dimensions, wire gauge and wire length are customized to your drawing or sample; OEM/ODM supported.

Q4: Is the spring-ring variant necessary for my application?​
It is recommended for vibration-heavy duty — battery packs, engine bays and mobile equipment. For static panels, the standard U-shape is sufficient; tell us the environment and we advise.
