Battery contact clip 50

Huizhou Antenk Electronics Co., Ltd., an IATF16949:2016, ISO9001 and ISO14001 certified manufacturer founded in 2004 with over 250 employees and a 10,000m² facility, proudly presents the Battery Contact Clip 50 – a low‑profile, surface‑mount retention clip specifically engineered for coin cell batteries (CR2032, CR2025, CR1616) and small cylindrical cells (up to 12mm diameter). Unlike traditional battery holders that require through‑hole mounting and occupy significant PCB real estate, the Clip 50 features a compact C‑shaped stamped body with integrated solder pads for fully automated SMT assembly. Manufactured on our 11 Japanese/Taiwanese high‑speed stamping presses using 0.15mm beryllium copper (or phosphor bronze), the clip provides a reliable normal force of 40–60g with a gold‑plated (0.5μm) contact area, ensuring ultra‑low contact resistance below 25 milliohms. Key characteristics include an installed height of just 2.2mm above PCB, support for continuous currents up to 200mA (peak 500mA), operating temperature range -40°C to +105°C, and an integrated polarity key to prevent reverse battery insertion. The open clip design allows visual inspection of battery presence. The product is RoHS, REACH compliant and UL recognized (E472792), with 100% automated optical inspection.

 

Application Scope: The Clip 50 is ideal for compact, high‑volume electronics where manual battery holder assembly is impractical, including wearable fitness trackers, smart watches, wireless earbud charging cases, IoT sensors, medical patches, active RFID tags, portable glucose meters, key fobs, and memory backup circuits on PC motherboards – markets where Antenk already supplies customers in the USA, Germany, South Korea, India, Russia, and beyond. Usage Method: The Clip 50 is supplied on tape‑and‑reel (500pcs/reel) for automatic pick‑and‑place. Solder the two SMT pads using standard reflow soldering (peak 260°C, recommended stencil thickness 0.12mm). After soldering, insert the coin cell (positive side facing the clip’s raised dimple) by sliding horizontally under the retaining arm until it snaps into place. The clip provides tactile feedback. To remove, use a plastic pry tool to lift the battery edge – the clip’s spring arm allows vertical extraction. Precautions: Do not exceed 200mA continuous current; ensure PCB land pattern matches the recommended footprint (available in datasheet); avoid reflowing more than twice; operate within -40°C to +105°C range. Advantages Over Competitors: Unlike competitors who use separate stamped contacts that require manual handling or secondary assembly, Antenk’s Clip 50 is a complete SMT‑ready solution that eliminates manual insertion steps – reducing assembly cost by up to 40%. Competitors often use tin‑plated steel that oxidizes and loses spring force after 1,000 cycles; Antenk uses beryllium copper with gold plating, maintaining 90% of initial spring force after 10,000 cycles. While others require 20,000+ MOQ for custom SMT tooling, Antenk offers low MOQs (1,000 units) with no tooling fees for standard CR2032 geometry. Our IATF16949 certification ensures automotive‑grade quality. Additionally, our 72‑hour salt spray testing and 15,000‑cycle battery insertion validation guarantee reliable performance in portable and medical devices.

 

Antenk’s vertical integration delivers consistent quality for the Battery Contact Clip 50 SMT version. Process flow: (1) In‑house mold design using our 180+ precision terminal molds (dedicated C‑clip progressive die with 14 stations for forming, coining, and cutoff); (2) High‑speed stamping on Japanese/Taiwanese presses (11 machines) using 0.15mm beryllium copper strip – the material is pre‑heat‑treated for consistent spring properties; (3) Selective barrel plating: nickel underplate (2μm) + gold on contact tip (0.5μm) using precision masking; (4) 100% AOI dimensional inspection with critical tolerance of ±0.05mm on clip height and arm deflection; (5) Spring force testing per EIA-364-04 at 1.8mm compression (simulating CR2032 thickness); (6) Contact resistance testing per EIA-364-06; (7) 72‑hour salt spray corrosion testing; (8) Tape‑and‑reel packaging with 500 pieces per reel, including 100% coplanarity check; (9) Final QC with lot traceability and full dimensional report. Our laboratory houses 20+ testing devices including profile projectors, XRF for gold thickness, environmental chambers, and automated spring testers. With 250+ employees, 18+ mold‑making machines, and 180+ automatic assembly machines, we provide free samples, complete 2D/3D CAD drawings with recommended PCB land pattern, and 24‑hour technical support.
