What Is A Wire Ferrule?

One of the most common items found in electrical applications is a wire terminal. The uses are countless, and they frequent industries such as automotive, industrial, manufacturing, marine, solar, and more. A wire ferrule, though notably not as well known as a wire terminal, is a growing product that is being used more and more every day. Already commonly used in Europe, the wire ferrule is becoming increasingly utilized throughout the globe. Even with this exponential growth, many questions about wire ferrules persist.

What is a wire ferrule?

A wire ferrule is crimped to the end of a stripped wire, very similar to a terminal. When it is crimped onto a stranded wire, it protects the fine strands from fraying. They are then inserted into the terminal compartment to be crimped onto the wire.

What is the difference between a wire ferrule and a terminal?

A wire ferrule usually differs in where it is crimped in comparison to a terminal. A wire ferrule is crimped in the metal tube itself instead of where the insulation covers the barrel. The metal tube in which a wire ferrule is crimped does not extend into the insulation. This difference is easily seen in the appearance of both a wire ferrule and wire terminal.

What are the benefits of a wire ferrule?

Wire ferrules are seen in countless industries where power distribution and connections are needed. They are especially common in automotive or industrial applications and are frequently used with screw type terminal blocks. A wire ferrule provides benefits over simply inserting the bare wire strands. Boasting benefits such as no strand fraying, better contact, easier repeated insertion and removal from terminal, and strain relief; the ferrule is no stranger to connections. Many who use wire ferrules enjoy the benefits of the repeated insertion and removal to aid in long term projects.

What types of wire ferrules are available?

Del City offers insulated wire ferrules, twin insulated wire ferrules, and non-insulated ferrules. This variety ensures there is a wire ferrule for almost every application. The insulated wire ferrules offer a larger guide for inserting the wire strand. This helps to ensure a minimum bend in tight spots. The insulation is color coded for ease of determining gauge size. A twin insulated wire ferrule provides the same benefits of insulated ferrules, but allow for the crimping of two wires. If your project does not need an insulated ferrule, non-insulated are also available. Del City also offers wire ferrule kits of various sizes offered in the three types of ferrules described above.
