The Non-Insulated Butt Splices Terminal (BN Series) is a fundamental electrical fastening component engineered for seamless end-to-end wire splicing. Designed for environments where pre-insulated terminals are unnecessary—or where heavy-duty heat shrink tubing will be applied post-crimping—these bare butt connectors provide the most direct and secure electrical pathway possible.

Manufactured from high-purity copper and finished with a protective tin plating, our butt splices deliver outstanding electrical conductivity while actively resisting corrosion and oxidation. Whether you are repairing automotive wire harnesses, assembling industrial control panels, or splicing low-voltage circuits, these uninsulated connectors guarantee a flawless, low-resistance joint. Fully compliant with CE and RoHS standards, they are the professional choice for safe and durable electrical installations.

Premium Material Construction: The terminal body is forged entirely from high-quality copper, ensuring minimal voltage drop and maximum current flow across the splice.
Corrosion-Resistant Plating: A robust tin plating covers the copper body, preventing rust and degradation even in humid or harsh operating environments.
Intelligent Wire Stop Design: Featuring a central indentation (wire stop) in the barrel, these connectors prevent the wire from being over-inserted, ensuring both wires meet perfectly in the center for a balanced, symmetrical crimp.
Broad Wire Compatibility: The BN series accommodates a comprehensive range of wire gauges, specifically supporting 26-22 AWG, 22-16 AWG, 16-14 AWG, 14-12 AWG, and 12-10 AWG.
High Safety Standards: Engineered for low voltage applications (below 50Vac or 75Vdc). These terminals contain no high-concerned chemicals and are fully RoHS certified.
Because of their uninsulated, slim profile, the BN Series Non-Insulated Butt Splices Terminals are incredibly versatile and widely used across numerous industries:
Automotive & Marine Wiring: Ideal for repairing wire harnesses or extending cables where custom, waterproof heat-shrink tubing will be applied over the splice.
Industrial Automation: Used extensively in PLC cabinets and motor control centers for permanent, vibration-resistant wire extensions.
Telecommunications: Splicing low-voltage communication cables safely and efficiently.
Consumer Electronics: Internal wiring repairs and component assembly where space is strictly limited.
Creating a secure splice with these butt connectors is a fast, 3-step process:
Preparation & Insertion: Select a connector to suit your specific wire size, strip the wire insulation, and insert the bare copper strands into the terminal barrel until they hit the central wire stop.
Professional Crimping: Using a professional crimping tool, firmly crimp one side of the terminal to secure the first wire in place. Repeat the process for the opposite side.
Finalization: The terminal connection is now finished, resulting in a highly conductive, mechanically strong joint.
