Knowledge of Punch Down Tool

Introduction of Punch Down Tool

Punch down tool, also called punch down tool or krone tool (named after the KRONE LSA-PLUS connector), is a small hand tool used by telecom and data network technicians to install wiring for telephone, computer and various audio network, designing for inserting wire into insulation-displacement connectors on punch down blocks, patch panels, keystone modules, and surface mount boxes (also known as biscuit jacks). Its name is derived from the method by which the tool pushes a solid copper wire between metal blades on the connection block and cuts off the excess by punching the tool, driving the tool blade through the wire.

Applications of Punch Down Tool

Punch down tool is commonly used for termination works in the coppper network builted by twisted-pair cables like the Cat5, Cat5e, Cat6 and some newer standard Ethernet cables. With cables terminated with keystone jacks, cross-connect blocks or patch panels, networks run smoothly, enhancing working efficiency and reducing losses. For instance, it is widely used by IT staff to ensure successful connections between computers and data centre, maintaining a high level of transmission.

Tips When Using Punch Down Tool

Procedures

  • Hold the wire in your hand and lace it through the correct slots on the connection block. Repeat with other wires that need to be inserted in the connection block.
  • Hold the punch down tool with the blade facing down. Align the blades with the wires on the connection block.
  • Punch down the wire by holding the wire and pushing the tool firmly into the block. This should connect the wire to the terminal and cut off any excess wire at the same time.
  • Test the connection you just created. Pull on the wires to make sure they are attached properly.

Note: It is essential that the tool blade should not cut throughout the wire insulation to make contact, but rather the sharp edges of the slot in the contact post itself slice through the insulation. In addition, punch down tool is also used to cut off excessive wire in the same operation.

Warnings

  • Always wear safety glasses when using a punch down tool.
  • Models with interchangeable blades will extend the life of your tool.
  • Use the pressure adjustment screw or knob to set the tool to a comfortable level for your use.
  • Never use a punch down tool to tighten flat head screws because this can break the cutting blade.
  • Although the tool is usually made of plastic, there still is a shock hazard when working with electrical circuits.

Punch Down Tool of Network Cabling Tools

A punch down tool (also known as punch down tool or krone tool) is needed to quickly and efficiently connect cable wires to electrical contacts. Not only do these tools make faster connections, but because many connecting blocks like 66-type or 110-type are designed for use with these punch down tools.

It’s not only a Network Cable Crimper for terminating Cat 5, Cat 5e or Cat 6 cables, but it also will punch down a 110 IDC RJ45 jack. It’s a quality piece of equipment. To successfully create Ethernet jacks that computers connect to and for terminating Ethernet cables in a way that does not impair the data signal, IT workers need the right tools. Crimpers are used to terminate RJ45 heads—the little plastic plugs that allow an Ethernet cable to fit either into an RJ45 wall jack or the Ethernet port on a computer. Crimpers that did not have the right amount of pressure to make a good crimp as well as the sometimes-flimsy punch down tool that comes with RJ45 jacks—making wiring time-consuming and frustrating.

Common Features of Punch Down Tools

Typical on the market there are three different punch down tools available, including standard impact tool, universal automatic impact tool and corrosion resistant termination tool. Most punch down tools are of the impact type, consisting of a handle, an internal spring mechanism, and a removable slotted blade. They typically are 6-8 inches long with a blade at one end. The top and bottom of the tool are usually different colors to help users identify which side is used to cut the wire. Most models have a changeable blade and a pressure adjustment screw or knob.

The dimensions of the punch down tool are not standardized. Some tools measure 5.35 in x 1.06 in x 1.06 in and weigh 4.69 oz. Others have dimensions of 5.25 in x 1.26 in x 1.26 in, 7.00 in x 2.02 in x 2.02 in and so on. Their weights also vary. Whatever the dimensions of the punch down tool are, usage is the same.

How to Use a Punch Down Tool?

1. Prepare to punch down a wire.
Standing in front of the connection block, hold the punch down tool in one hand, with the cutting blade facing down. Hold the wire in your other hand and loop it through the selected connection block terminal.

2. Punch down the wire.
Holding the end of the wire firmly, place the blade of the punch down on the selected connection terminal and push forward until you reach the bottom of the terminal. Continuing to hold the end of the wire, punch the tool firmly with a straight-forward motion. If done correctly, this action should connect the wire to the terminal and cleanly cut off any excess.

3. Check your connection.
Make sure your connection is secure and there is no loose or broken wire left in the connection block. Tug on the wire to verify that it is securely fastened and connected to the correct terminal.

There are many types of punch down tools available and have different features. The good ones will have reversible blades. This can be handy in many instances. It is also important for the blade to fit in properly. The tool must also be robust. Find other fiber optic tools at Fiberstore.
