Crimping Tool Explained

Before we go into defining what a crimping tool is, let’s first look at the meaning of the word crimping. Simply put, crimping is the process of joining metallic materials or other ductile pieces by deforming one or both of them. This deformity is what is referred to as the crimp, and it is what enables the materials to stay together.

A crimping tool, therefore, is a device that is used to join two ductile pieces by deforming one or both of them to hold them together. Rather than using the crimping tool, many homeowners majorly use flat stones, hammers or other improvised tools to join the pieces together. This procedure, however, leads to poor quality of the work done or total failure, hence the need for a crimping tool.

Uses of a Crimping Tool

One of the most common uses of the crimping tool is to conjoin a connector and a cable. Network and phone cables, for instance, are created with the help of a crimping tool by joining connectors to both ends of the cables. RJ-45 and RJ-11 are the most common connectors that can be attached to the end of a cable. Attaching a connector is a very crucial part of crimping, as it prevents the wires from falling apart. The connector also helps transmit data to the wires.

Now, asides from the aforementioned, there are likewise several other uses of the crimping tool which includes securing the lids on metallic food cans, joining metal sheets during the installation of ventilation pipes etc. The crimping tool is also used in manufacturing jewellery when there is a need to make secure joints. Having said so much about the crimping tool, let’s now consider how it works.

How Does It Work?

  • To join a cable and a connector together with a crimping tool, the operator needs to first match the terminal end of the connector with the wire size.
  • Once this is done, the wire is ripped with the help of another tool — the Wire Ripper. The amount of wire that would be ripped off is dependent on the length of the connector.
  • The ripped wire is then fitted into the connector, and they are both inserted into the crimping tool.
  • The operator then presses the tool’s handles to squeeze the wire and connector together. At the end of this, the wire and connector are now firmly connected.

Before installation, however, the operator needs to be sure that the crimping was properly done to prevent failures after installation. This can be done by tugging the connection apart. If the connector and wire pull away, it means the crimping was not done properly.
