Wire Terminals

Essential elements of electrical and electronic devices are the wire terminals, which are built to guarantee a good, safe, and reliable connection to and between wires and those devices. For many years, certain basic wire terminal styles have been around and in general use: those with rings, those with flat, notched spade-type ends, those with thin, flat "blade" ends.

Terminals are typically made from conductive materials like copper or brass, often plated with metals like tin. They hold wires in place while also ensuring efficient electrical current flow into and out of wires.

The most frequently used technique for attaching wire terminals is crimping. This involves using crimping tools to squeeze (or "crimp") the metal terminal around the stranded wire, both mechanically and electrically. Some terminals can also be soldered, for added reliability. Install wire terminals properly, and you'll get good, low-resistance, low-heat connections, which makes for both an effective and safe electrical system.
