Using And Crimping Wire Ferrules

Today we are going to introduce the ferrules and give several examples. Moreover, we will continue to discuss the advantages of ferrules and reasons to use them. And we will end in talking about how to use ferrules.

Come To The Question Of What Ferrule Is

The image may show in mind that a small metal tube with a colored insulated plastic end. And thanks to the plastic end, we can insert wire strands and crimp the tube securely to the wire. However, dictionary websites generally provide two main definitions for ferrules. While it can be a metal ring or cap usually put around a slender shaft to strengthen it or prevent it from splitting, it can also be a metal sleeve used for joining or binding one part to another.

Thus, there are a large variety of ferrules which come in different shapes, forms and materials and are used for many purposes. To make it clearer, we take several examples to illustrate the definition. A ferrule may be the metal sleeve holding the eraser securely on a pencil as well as a metal band that secures a paint brush bristles to the handle. Also, it can turn to be the ferrules used for wire termination. These “crimp wire ferrules” are used for electric or electronic wiring and for the specific purpose of providing a very nice, clean and safe termination for wire strands, which in turn provide an efficient and safe connection to a terminal block.

Merits Of Wire Ferrules

As one of the most effective components used in daily life, wire ferrules can offer many advantages that support the decision to make use of them. Firstly, they are really helpful to reduce the use of stray strands, which is the most common benefit. As the stranded wires with ferrule they are installed into the ferrule, they are less likely to separate due to the natural funnel design of wire ferrules. More than that, any strands that are separated while get installed into the ferrule are easier identified when we hold the wire in hand in optimal lighting. Secondly, a wire ferrule on the end of the wire allows repeated insertion and removal, without degrading which can greatly reduce the occurrence of suffering from a degraded, unreliable, and potentially dangerous termination point. Moreover, stranded wire with wire ferrules together with solid wire, stranded wire can prevent connection failure. In short, wire ferrules can make a nice, clean and secure connection to a terminal block so that they can prevent wire strands from spreading out of a terminal possibly causing a short and they are able to  provide sufficient contact to wire.

How To Connect Wire Ferrules

Finally, here comes to a question on how to use wire ferrules as they are widely under used by many techs in the field. To begin with, we should choose an appropriate sized ferrule for the wire we are using. Then, we should strip the insulation from the end of the wire and make sure that the length of insulation is equal to the barrel length of the ferrule. After placing the ferrule over the bare metal strands of the wire, we should insert the ferrule and wire into the closely-sized notch on the crimp tool and squeeze the handles of the crimp tool together firmly to lock the ferrule onto the end of the wire.
