Continuous Commitment to Process Innovation! Suzhou Menhow Granted Invention Patent for Terminal Crimping Die
2026-07-31
Recently, the China National Intellectual Property Administration has officially issued a grant for the invention patent A Terminal Crimping Die, Device and Process. It covers core production modules including precision fitting tooling, on line inspection jigs, process error proof structures and automated supporting devices, marking another core technological advantage achieved by the enterprise in the field of precision processing for wire harness terminals.
Terminal crimping is a critical process for electrical conduction manufacturing of wire harnesses and printed circuits. The connection reliability between terminals and flexible printed electronics directly affects the operational stability of electronic products. Conventional crimping processes frequently suffer from insufficient clamping force and poor electrical contact between wires and terminals. Defects such as loose joints and signal interruption often occur after long term vibration or repeated bending, bringing hidden risks to end product performance.
This newly granted patent adopts an innovatively optimized die structure. Multiple arc shaped semicircular deformation grooves are provided on the upper die. During stamping, terminal claws deform orderly along the grooves and embed into wires, which significantly boosts connection strength and effectively improves the stability and durability of wire harnesses. Meanwhile, the supporting terminal crimping equipment and complete production workflow enable large scale mass production application. It helps improve the yield and production stability of printed circuit products such as membrane switches,capacitive touch films and printed Ecg electrode for medical, lowering overall production reject rates.
