Description
Insulated Fork / Spade Terminal Connector (6.3mm)
Product Overview
The Insulated 6.3mm Fork Terminal (also known as a spade terminal) is engineered to provide secure, permanent wire terminations for screw-down terminal blocks and barrier strips. Featuring a reinforced, high-conductivity brass or copper alloy fork piece housed within a rigid vinyl (PVC) insulation sleeve, this terminal allows for rapid installation and removal without completely removing the fastening screw.
The open-ended fork design features slightly upturned tips or precise dimensioning that slips cleanly beneath standard 6.3mm screw heads, ensuring maximum surface area contact and high vibration resistance in critical wiring arrays.
Key Features
-
Time-Saving Open-Ended Design: Permits swift attachment and detachment from terminal strips by simply loosening the screw—no need to fully back out screws, reducing maintenance downtime.
-
Flared Insulation Sleeve Entry: Designed with a funnel-shaped internal barrel that guides stranded wires smoothly into the crimp zone, preventing loose or bent strands.
-
Internal Wire-Lock Serrations: The interior of the metal barrel features micro-grooves that bite into wire strands upon crimping, ensuring superior tensile pull-out strength and maximum current transfer.
-
Anti-Vibration Fit: Precision-engineered gap dimensions allow the fork to lock tightly around the screw stud, minimizing the risk of backing out under physical or mechanical vibration.
