Product details
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 in Shenzhen and Dongguan, proudly presents the AA Battery Terminal Model 1045 – a dual-ended integrated battery terminal designed for series connections without requiring separate connecting wires or PCB traces. Unlike conventional battery contacts that require external circuitry to link multiple cells, Model 1045 features a one-piece stamped conductor that simultaneously serves as the negative contact for one AA battery and the positive contact for an adjacent AA battery, creating an instant series connection. Manufactured on our 11 sets of Japanese/Taiwanese high-speed stamping presses using premium phosphor bronze (C5191) with nickel or selective gold plating, this terminal delivers ultra-low contact resistance below 12 milliohms end-to-end. Key characteristics include a reinforced central bridge section rated for 5A continuous current, independent spring arms on both ends providing 80–110 grams normal force per cell, reliable operation from -40°C to +100°C, and an integrated polarity indicator (+/-) embossed on the terminal surface. The product is RoHS, REACH compliant and UL recognized (E472792), with 100% automated optical inspection on every batch.
Application Scope: Model 1045 is ideal for multi-cell AA battery configurations where PCB space is limited or wiring complexity must be minimized, including 3V/4.5V/6V battery packs for portable instruments, DIY electronics projects, educational kits, backup memory power modules, wireless sensors, emergency lighting, children's electronic toys, and prototype breadboard power supplies – markets where Antenk already supplies customers in the USA, Germany, South Korea, India, Russia, and beyond. Usage Method: No soldering is required for the series connection itself. Place the Model 1045 terminal between two AA batteries with proper orientation: the embossed "+" side contacts the positive terminal of one battery, while the flat spring side contacts the negative terminal of the adjacent battery. For PCB integration, solder the provided PCB mounting tabs (pre-tinned) to your board. The terminal can also be used as a free-standing bridge in battery holders. Precautions: Do not exceed 5A total current; verify polarity markings before final assembly; ensure both batteries have similar charge levels; do not bend the central bridge more than 5 degrees. Advantages Over Competitors: Unlike competitors who require separate jumper wires, PCB traces, or spot-welded nickel strips to create series connections (adding cost and assembly steps), Antenk’s Model 1045 integrates the series connection directly into the terminal – reducing BOM by eliminating wires and cutting assembly time by 70%. Competitors often use thin 0.20mm material that creates excessive voltage drop; Antenk uses 0.35mm phosphor bronze with a wide 4mm bridge for minimal resistance. While others require 10,000+ MOQ for custom bridge lengths, Antenk offers low MOQs (1,000 units) with no tooling fees for standard center-to-center spacing (50mm for AA). Our IATF16949 certification ensures automotive-grade quality management. Additionally, our 48-hour salt spray testing and 10,000-cycle validation guarantee reliability even in high-vibration portable devices.
Antenk’s vertical integration delivers consistent quality for Model 1045 dual-ended bridge terminal. Process flow: (1) In-house mold design and fabrication using our 180+ precision terminal molds (dedicated dual-ended progressive tooling with 20+ stations including coining operations); (2) High-speed stamping on Japanese/Taiwanese presses (11 machines) using 0.35mm phosphor bronze strip – the central bridge requires precise grain direction control to prevent cracking; (3) Barrel plating (nickel/tin/gold) with real-time thickness monitoring – uniform plating across both contact ends and bridge essential; (4) 100% AOI dimensional inspection with critical tolerance of ±0.08mm on contact positions and ±0.15mm on overall length; (5) Independent spring force testing per EIA-364-04 for both end contacts; (6) End-to-end contact resistance testing per EIA-364-06 across the entire 50mm bridge; (7) 48-hour salt spray corrosion testing; (8) Automated assembly on 180+ machines with polarity verification (embossed markings); (9) Final QC with lot traceability and full dimensional report including bridge flatness measurement. Our laboratory houses 20+ testing devices including profile projectors, hardness testers, environmental chambers, and four-wire Kelvin resistance testers for bridge resistance validation. With 250+ employees including dedicated engineering and QA teams, 18+ mold-making machines, and 250+ plastic injection molds, we provide free samples, complete 2D/3D CAD drawings showing bridge geometry and mounting tab locations, and 24-hour technical support. Contact Antenk today for a quotation – we typically respond within 4 hours and ship AA bridge terminal samples within 3 days. Ask about our volume discounts (5,000+ units) and custom bridge lengths for non-standard battery spacing (AAA, C, D cell configurations available). With 70% of our products exported worldwide and 18 years of experience, Antenk is your trusted partner for innovative battery terminal solutions that simplify series connections and reduce assembly costs.
