The information about the ferrule terminals

What is a Ferrule? I'm thinking about how to explain the introduction of ferrule terminals to you. This is a small metal tube with coloured insulated plastic ends where you can insert strands and crimps safely into the wire. I try to find the answer on the Internet to see what could be found to describe the metal hoop. But there is too much different pictures and products on it.


The ferrule is a kind of soft metal pipe, which is pressed at the end of multiple wires to improve the connection characteristics of wires. Most metal hoops are made of copper, which is usually tin-plated. The size of the ring is suitable for specific specifications of wire, whether in diameter or length. However, metal hoops are more than just a simple cylinder-one end has a lip or horn, and when metal hoops are inserted into metal hoops, they are used to collect and consolidate wire strands. The cross section of an insulating ring mounted on a twisted wire. This is pre-insulated ferrule terminals.

How to use the ferrule terminals

The bell mouth in most metal hoops is not obvious because it is usually wrapped in a conical plastic cable leading into the casing. The bushing acts as a transition between the insulating layer of the wire and the metal hoop itself. It can also corrode all loose strands into the cavity of the metal hoop. Unlike the traditional press connection, the plastic sleeve of metal hoop will not be compressed during installation. It maintains integrity around the insulation and provides some measures to eliminate strain after installation by removing the bending radius of the conductor from the insulating end. The utility model is composed of a tin-plated copper tube and a polypropylene fluoropolymer insulating ring at the insertion end of the cable. These coils have a variety of coil colors and tube sizes and are designed to accommodate the wires of the American Gauge 20-1.


(1) The wire is stripped to the approximate length of the ferrule tube and inserted into the (2) ferrule while ensuring that all wire strands slide into the tube. Then the ferrule is (3) crimped on the metal tube portion with a crimp tool leaving a (4) nice tight hold on the wire strands and providing an easy way to insert the crimped portion into a terminal block to easily and effectively secure it with the set screw.

How to select the ferrule terminals

Now we know the Ferrule Terminals applications, then we can learn how to select the high quality ferrule terminals. Follow below tips to have the professional selection of Ferrule Terminals. You need know which tube it use together with firstly. Pressing tools are hexagonal or square and provide pressure joints with the same cross-sectional area. The selection of the contour to be used depends on the shape of the hole in which the wire will be inserted. Square folding is more suitable for rectangular holes, while hexagonal folding is more suitable for circular holes. These metal wire rings also have bimetal wire models. The double conductor ferrule has a larger insulating ferrule, which allows you to insert two wires into the ferrule and press them tightly together with a suitable size ferrule (space must be reserved for the two wires).And ferrules have some special advantages, and they are more and more recognized because they have good engineering significance. Next you should choose the one which has good material and a reliable manufacturer. Finally you can ask the quality warranty. A good one should have the long service life.
