  • Ferrule pliers belong to the family of crimping tools because they pinch wires in a sleeve by crimping (so-called crimping).
  • About the end of a line, a sleeve is inserted, which is compressed by the wire end clamp. The connection is airtight and tensile.
  • The different types of ferrule pliers differ in their compression form: V-shape, rectangle, square, trapezoid and hexagon.

1. When is the wire end clamp used?

Ferrule Pliers Comparison 2018: 2018

Wire end ferrules are pressed together in the pliers.

Since wire end pliers belong to the crimping tools, we will first discuss the so-called "crimping" here:

If entisolierte cable ends to be connected to other bare cable ends, you can either twirl, solder or connect by means of a ferrule. A sleeve has the advantage that it protects the connection at the same time.

The bare ends of several cables or Litz wires are inserted into the ferrule and pressed together with the crimping tool, After pressing, the sleeve retains its given shape. The cable ends were now "crimped".

Ferrules are either completely or partly made of metal.

The enclosed cables are firmly connected so that they can no longer be pulled apart. If the pressing tongs have been properly set, then such a composite may even be airtight.

There are many varieties of crimp sleeves: Some are used to connect two cables. These are often made of plastic. Others just stabilize the end of a cable so it can be used as a plug.

Sleeves for these inserts consist either completely or partly of a current-conducting metal. These are e.g. Wire end ferrules or cable lugs.

Well packed: Airtight cables are important in environments where flammable gases can escape. Here a spark from the cable connection would otherwise ignite the gas.

Advantages and disadvantages of crimping over soldering:

  • more quickly
  • robust
  • Ends can be used as plug
  • Sleeve may fall off
  • can damage the cable

The wire end sleeve pliers

The cable lug

Cable lugs are crimp sleeves that have an uninsulated metal ring or plug at one end. Cable ends are "attracted" to the cable ends, if these, for example make electrical contact with a screw should.

The name of the pliers already gives decisive hints:

  • Core = cable
  • The End
  • Sleeve = wire end ferrule

Wire end ferrules are crimp sleeves that are placed on the end of a wire (ie a cable). As a rule, they are used with stranded cables, A stranded wire consists of several thin wires that break off easily.

If the end of a stranded wire is to be plugged into other parts, it is very expensive to insert them safely. To protect the stranded ends, they are put into a robust sleeve and "crimped". The resulting "Crimpstecker" is very robust.

2. Five types of ferrules pliers

Ferrule Pliers Comparison 2018: ferrule

This is how a finished pressed end sleeve can look like a V-shape.

In the trade you will surely find other variations of crimping tools. But in our Ferrules Pliers Comparison 2018 Let us introduce you to the most common basic forms.

The five categories mentioned refer to the final result of the pressed ferrule, because this is later used as a plug (crimp contacts). The shape refers to the cross section through the finished pressed ferrule.

Ferrules formparticularities
V-shapedIt can also be called a "thorn" or half-round shape, since a "spike" or semi-circular web presses into the sleeve.
rectangleThis is not a fixed format, but the sides are evenly pressed at 90° to each other.
squareThe complete sleeve is pressed into a perfectly square shape.
trapezeThe sides of the sleeve are straight, but are at any angle to each other.
hexagonSimilar to a hex nut here are the sides of the sleeve shaped. This shape allows particularly compact pressures.

3. Purchase advice for wire end clamps: You must pay attention to this

3.1. Capacity range: The sleeve circumference

Ferrule Pliers Comparison 2018: pliers

The different sizes of ferrules are given by the square millimeter of the cross section.

Since there are different lengths of wire end ferrules and cable lugs, crimping tools can handle many different sizes. However, crimping tools are not suitable for all wire end ferrule sizes.

Pay attention to the so-called "wire end ferrule" "Capacity range". This indicates for which sizes the pliers have capacities. These are given in square millimeters of the sleeve cross-section.

For example, wire end ferrule sets with sizes from 0.25 to 16 mm² can be found. However, you should keep an eye on which sizes are actually depicted on the jaws of the forceps. Do you want special If you combine thick or many cables in a ferrule, you need a particularly large diameter.

The various sizes generally correspond to standardized components in the field of electrical engineering. There are often prepared cables for circuits.

3.2. automatic

Ferrule Pliers Comparison 2018: ferrule

The illustrated ferrule pliers automatically adjust to the circumference of the sleeve.

You are much more flexible if the wire end clamp is self-adjusting. The pliers automatically adjust to the correct size of the sleeve, Thus, you do not need to pay attention to jaw sizes with pliers for wire end sleeves with automatic cross-section adjustment.

3.3. forced pressure

Forced squeezing is a mechanism in the tool that prevents the tongs from prematurely bursting when compressed. These Forced lock thus ensures uniform and uniformly pressed sleeves, Most self-adjusting crimpers and ferrules have this feature.

3.4. Length and ease of use

Use the handles to bring power into the pressing process. If you press hard here, it will be uncomfortable if the handles are too hard or angular. Pliers handles with a rubber or plastic coating provide the highest comfort.

But also the length is decisive for ease of use. Long handles help to create better leverage. Bear in mind, however, that too long handles will fit worse in the tool case.

leverageThe longer the grips of a pair of pliers, the more power they build. But the user has to use less physical strength himself.

3.5. material

Ferrule Pliers Comparison 2018: comparison

A rubberized grip is particularly comfortable in the hand.

If you use a pair of crimping pliers or a ferrule pliers, inferior material will not be noticeable so quickly. However, pliers made of cheap iron can cause rust on the metal sleeve, The best ferrules are always made of steel or a steel alloy (e.g., chrome vanadium).

4. Frequently Asked Questions about Crimping Tool, Crimping Tool and Ferrules

4.1. How do I use crimping pliers for wire end ferrules?

Ferrule Pliers Comparison 2018: comparison

With crimp sleeve connections, the cables are inserted from both sides.

If you want to crimp like a pro, first strip the cable or stranded wire. If the stripping tool is missing in the tool box, a pocket knife is enough. However, a wire stripper works faster and more accurately.

Choose the smallest size under the sleeves, which can barely be pushed over the cable. Bed the whole thing in the right cheek piece of your crimping tool and push slowly but bravely to, Only when the clamp on the cheek lies on jaw, the ferrule is finished pressed.

Some strippers or crimpers are true multi-functional tools, as they occasionally provide both functions. For further repair tips in the electronics sector, Stiftung Warentest recommends the book "Reparaturen kompakt - Elektro + Netzwerk".

4.2. Which crimping tool is suitable for wire end ferrules?

Actually, all crimping tools are also suitable for wire end ferrules. However, some crimping pliers are also good for uninsulated cable lugs. This may not necessarily be every ferrule pliers. Crimping tool sets usually contain wire end ferrules or cable lugs that are suitable for the tool.

4.3. Which ferrule type do I need?

Ferrule Pliers Comparison 2018: ferrule

With exchangeable pliers jaws you are prepared for many sleeve sizes.

Even a cheap wire end pliers is still too expensive, if the shape of the cross section is not correct. Core ferrules become defined by the shape of the pressed ferrule: V shape, rectangle, square, trapeze and hexagon.

Depending on where you want to plug in the cables, you need a specific shape. If you are unsure, choose a crimping tool with exchangeable jaws.

4.4. Which crimp and ferrule manufacturers and brands are available?

Knipex is very popular in the pliers area and therefore as a manufacturer of crimping tools. But a potential end-sleeve test winner does not necessarily have to come from the workshops of Knipex. The following manufacturers also bring good pliers to the market:

  • Alpha tools
  • lux
  • master
  • Weidmüller
  • Wiha
  • bison
