Rectangular Copper Terminal Block with Busbar Terminal Connector and Four Countersunk Mounting Holes

Countersunk hole position tolerance and copper purity grade govern fit for a rectangular busbar terminal connector; hole position outside ±0.05 mm from the bolt pattern nominal displaces the terminal from the conductor centreline, creates stress at the fastener shoulder, and raises resistive heating at the contact interface under rated current in battery management, power distribution, and energy storage applications. C101 oxygen-free copper maintains conductivity above 100% IACS and is specified for busbars at current densities above 3 A/mm², while C110 electrolytic tough pitch suits lower-current applications where machining cost takes priority. Zhejiang Bolei Electric (Taizhou, Zhejiang, established 2008) machines this rectangular copper busbar terminal connector with four countersunk mounting holes at their around 30,000 m² Taizhou facility, IATF 16949, ISO 9001, ISO 14001, ISO 45001, and CE marked, with hole position, surface flatness, and bore diameter checked using your drawing as reference at initial sample inspection, serving automotive, aerospace, and military applications. For pricing, provide hole position tolerance, copper grade, surface flatness, and current rating from your print. For a production proposal from our taizhou facility.
