A reliable source for Ferrules information and leading Ferrules Companies & Suppliers.

Ferrules are defined as any ring used to reinforce a shaft or bring material strands together. A ferrule is generally a small, deformable tube made of tin-plated copper in the context of wiring. A great benefit to ferrules is that they minimize the contact resistance between the connector and the wire. Ferrules also help in reduction. Ferrules are available in different and various colors, depending on the wire that requires it to be crimped. Read More…

Construction of a Ferrule

The construction of a ferrule is a very simple process. The metal part is made up of copper and covered with tin. The sleeve is of PVC material or polyamide. Proper caution should be taken with its diameters. Usually, the ferrule is matched to the cable cross-section where it will be connected. For example, a 2.5 ferrule will have to be connected to a cable that is 2.5 mm^2.

How Ferrules Function

Most ferrules are made up of a circular clamp used to attach and hold together posts, fibers, or wires, generally by crimping, swaging, or deforming the ferrule. This will permanently tighten the ferrule onto the parts that need to be held. As the ferrule is driven axially into the fitting body, radial compression of the body's angled shape occurs, thereby pushing the end part of the ferrule onto the tubing's outer diameter.

Types of Ferrules

Various categories of ferrules are available in the electrical marketplace. However, there is a wide range of ferrules that are different from others and perform different purposes. Wire ferrules are those in the form of a pin terminal used to stop the unraveling of the stranded wire and maximize the electrical connection stability. They ensure safe and reliable connections and minimize the breakage caused by bending, vibration, or wire stress. Wire ferrules facilitate the insertion of the wire inside a terminal clamp. There are four types of ferrules: twin, insulated, single, and non-insulated.

Insulated Ferrule

The insulated ferrule consists of a sleeve which is plastic colored over a copper tube which is tin plated. Insulated wire ferrules allow for the visual color designation of the wire sizes. This will help in the quality inspection and identification. The insulated wire ferrule is much easier to work with, especially when working with smaller conductors. The ferrule offers and ensures a reliable connection. They can be made use in any type of application.

Uninsulated Ferrule

An uninsulated ferrule does not consist of a plastic sleeve. Its function is to prevent wire strands from breaking and fraying. Uninsulated ferrules are cost-effective and have a shorter length and uninsulated body. They offer many benefits when terminating in terminal blocks with narrow widths or smaller clamps and in printed circuit board terminal blocks.

Single Ferrule

A single ferrule is available in an insulated or uninsulated form. They can be crimped to one single cable. A single ferrule fitting consists of a single ferrule that grips the tubing and forms a leak-tight seal between the fitting body and the compression nut. In such a scenario, the single ferrule has two functions: sealing the fitting and locking it in its place.

Twin Ferrule

A twin ferrule can be crimped into two cables. Its diameters are larger, and it consists of specially-shaped sleeves that can take in two conductors that have different or the same size.This ferrule provides an efficient connection of multiple wires in one terminal clamp.
