This is a nickel-plated steel or phosphor bronze stamped part that creates a secure electrical connection between a toy's battery and its circuit board. You get a contact resistance below 20 milliohms, a spring hardness of HV 350–450, and a lead time of 3 days for standard tooling—all from a 20-year factory in Dongguan, China.
Most toy failures happen at the battery contact—not the motor. Our Toy Battery Contact Spring and Power Terminal uses full-hard phosphor bronze (C5210) or SUS301 stainless steel, depending on your current draw. We control the spring force within ±10% of your spec, tested over 10,000 compression cycles. The nickel plating is 2–3 microns thick, which prevents oxidation and keeps contact resistance stable even after months on a store shelf.
We hold stamped dimensions to ±0.02 mm on critical features like the terminal width and spring arm angle. That means your PCB pads align without rework, and the spring doesn't shift during vibration testing. For the power terminal's bend radii, we keep to ±0.05 mm—this prevents stress cracks in the material. If you need tighter, our EDM and wire-cut tooling can hit ±0.005 mm, but that's rarely necessary for toys.
For toys with motors drawing 500 mA or more, use C5210 phosphor bronze—it carries current without overheating and retains spring force up to 150°C. For simple LED or sound modules under 100 mA, SUS301 with a half-hard temper works and costs 15% less. We stock both materials in strip form, so your prototype and mass production use the exact same grade. No substitution surprises.
Standard finish is bright nickel plating (2–3 µm), which gives a shiny, corrosion-resistant surface. For high-end toys, we offer selective gold plating (0.1–0.3 µm) only on the contact point—this cuts cost while improving conductivity. If your toy is for outdoor use, we add a clear passivation layer that passes 48-hour salt spray testing per ASTM B117. You specify it, we stamp it.
We have 12 progressive die stamping presses, from 25 to 200 tons. For a new Toy Battery Contact Spring and Power Terminal, prototype tooling takes 3 days and costs $150–$300. Production tooling takes 10 days. And here's the key: we accept no MOQ for standard sizes. You can order 100 pieces for a pilot run or 500,000 for a global launch—the unit price adjusts accordingly, but the quality stays the same.
Every batch is checked with a 2.5D optical projector and a digital spring tester. We measure the spring's free length, compressed height, and load at 50% deflection. For the power terminal, we verify insertion force and pull-out force. A full inspection report is sent with every shipment—you get real data, not a certificate of convenience. If a dimension is out of spec, we sort 100% and re-run at no cost.
Parts are packed in anti-static trays or tape-and-reel, depending on your assembly line. For tape-and-reel, we use 12 mm or 16 mm carriers with 4,000 pieces per reel. Standard export cartons hold 50,000 pieces. Shipping from our Dongguan factory to Hong Kong airport takes 1 day; to the US West Coast, 4 days by air or 18 days by sea. We handle all export paperwork, so you don't need a freight forwarder.
