Products Description

This mechanical terminal lug is built for direct, secure connections between a power cable and a flat mounting surface. The conductor slides into a side-entry port and is locked in place by a top-mounted setscrew. An integrated flat palm, drilled with one or more holes, bolts directly onto busbars, panel boards, terminal blocks or equipment pads. The body consolidates the wire chamber, threaded screw location and mounting pad into a single, compact machined component. All critical dimensions can be tailored to match the cable diameter, available installation space, and hole-pattern requirements.

How the Connection Works

Performance depends on far more than external shape. The bore must be sized to grip the conductor firmly, the setscrew needs to generate consistent clamping pressure, and the palm must deliver a low-resistance contact area large enough for the electrical assembly. Before production, it is essential to verify the conductor metal, cable size, mating surface flatness, and recommended installation torque so the lug meets both mechanical and electrical expectations.

Design & Geometry Focus

This connector is purpose-engineered for cable-clamping and power-distribution tasks. Unlike PCB terminals, crimp-style lugs, or general aluminum hardware, the design centers on three functional zones: the conductor entry port, the compression screw system, and the mounting pad geometry. Every dimension works together to maintain a stable, low-temperature electrical joint under load.
