What is a ferrule crimp?

3 min read

Asked by: Illwill Taylor

A crimp ferrule – also known as a wire ferrule and electrical ferrule – is a soft metal tube that is crimped onto the end of a stripped wire to protect the strands inside a terminal from fraying. Most ferrules are made of copper.

What are ferrule crimps used for?

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.

Do you have to crimp a ferrule?


Making sure that all the wire strands are contained inside the tube place the ferrule into the crimper. And squeeze it until it. Releases. From there get a small piece of heat shrink.

When should you use ferrules?

So use ferrules when you want to increase the safety in your wiring. [1m:46s] Number two by using ferrules and your wiring, you create a much more consistent connection point. It can sometimes be difficult to get consistent results when stripping wire by hand, even when using tools that are designed to do so.

What is the purpose of an electrical ferrule?

An electric wire ferrule (sometimes electric end terminal) is a metal tube crimped over stranded wire to secure the strands within a screw terminal. Electrical insulation may be included to protect any exposed portion of the wire not completely inside the screw terminal post.

Where can I use ferrule connectors?

Length. So and then then just position it into the actual ferrule. Itself pop in there. So we're in and here's the guide again. So if I move that to one side going to use the guide again.

How do you crimp a ferrule without a crimping tool?

When you don’t have a ferrule crimping tool and you need to connect a ferrule terminal onto a flex electrical wire, you can do it temporarily with regular wire crimping pliers. Ideally, the regular wire crimpers are for crimping terminal connectors.

Can you crimp with regular pliers?

Regular Crimping Pliers are a must have tool for compressing 2x2mm or 2x3mm crimps. Regular Crimping Pliers allow for your design to be secure with a crimp bead that looks and feels smooth. Easy to follow instructions can be found in our Tips and Tricks section.

What is ferrule connection?

A pipe ferrule includes a circular clamp to connect together and join wires, fibers, or posts. It is a type of ring or cap that is connected to an object to protect from splitting, damage, or wear. Ferrules fittings are widely available in different sizes.

Do ferrules increase resistance?

Stranded wire-ends protected by ferrules are also much more resistant to vibration and breakage at the connection. In effect, ferrules produce a much more efficient and durable connection than can be attained with bare stranded wire, which results in significant savings over the life of the system.

Why is it called a ferrule?

The name evolved from Middle French “virelle” and Old French “virol” and ultimately from Latin “viriola,” meaning “small bracelet.” The “f” spelling of today’s “ferrule” was influenced by “ferrum,” the Latin word for “iron.”

What does a ferrule look like?

An asymmetrical ferrule is cone shaped, and can only be placed into the fitting body in one direction (usually with the tip of the cone facing into the fitting body). Symmetrical ferrules look like two cones back-to-back, and can be placed into the fitting body in either direction.

What are the different types of ferrules?

There are three different types of Wire Ferrules: Insulated, non-Insulated and twin.
