Why Wire Crimpers Are Important Tools

Wire crimpers are essential tools for anyone working with electrical wiring or cable assemblies. They are used to crimp, or compress, connectors onto the ends of wires, creating a secure and reliable connection. This is important because properly crimped connections are less likely to fail, ensuring the safety and reliability of your electrical systems.

Choosing the Right Wire Crimper

When choosing a wire crimper, there are several factors to consider. First, you need to consider the type of wires and connectors you will be working with. Different wire crimpers are designed for different wire gauges and connector types, so it's important to choose a crimper that is compatible with your specific needs.

Another important factor to consider is the quality of the wire crimper. High-quality wire crimpers are made from durable materials, such as hardened steel, and have precision-machined jaws that provide consistent and accurate crimps. Inferior-quality wire crimpers, on the other hand, may have jaws that are not perfectly aligned, which can result in poor crimps that are prone to failure.

Features to Look for in a Wire Crimper

When shopping for a wire crimper, there are several features to look for that can help ensure you get a high-quality and reliable tool. These include:

  • Adjustable crimping jaws: Some wire crimpers have adjustable jaws that allow you to crimp a wide range of wire gauges and connector sizes. This can be especially useful if you work with a variety of wires and connectors and don't want to have to buy multiple crimpers.

  • Built-in wire stripper: Some wire crimpers have a built-in wire stripper that allows you to quickly and easily strip the insulation from the ends of your wires. This can save you time and effort, and help ensure that your wires are properly prepared for crimping.

  • Ergonomic design: A wire crimper with an ergonomic design can help reduce hand fatigue and make the crimping process more comfortable. This is especially important if you will be using the crimper for long periods of time.

  • Durability: As mentioned earlier, high-quality wire crimpers are made from durable materials that can withstand heavy use. Look for crimpers that are made from hardened steel or other high-quality materials, and that have a reputation for durability.

Conclusion

In conclusion, wire crimpers are essential tools for anyone working with electrical wiring or cable assemblies. When choosing a wire crimper, it's important to consider the type of wires and connectors you will be working with, the quality of the crimper, and the features it offers. By taking the time to choose the right wire crimper, you can ensure that your electrical connections are secure and reliable, and that your projects are completed safely and efficiently.

Frequently Asked Questions (FAQs)

1. What are the two types of crimping?

There are two types of crimping: hexagonal crimping and indent crimping. Hexagonal crimping is used for aluminum and copper, while indent crimping is used for copper and aluminum. The quad-point crimp is specifically used for copper.

2. What can you use instead of wire crimpers?

If you don't have wire crimpers, you can use a small flat-head screwdriver to push down the pins into the wires. However, it's important to ensure that all the individual wires are pushed to the end of the jack before pushing down the pins.

3. How do I know which crimp tool to use?

Crimping tools are sized according to the wire gauge they can accept, using American Wire Gauge (AWG). It's also important to consider the type of terminal being crimped, as each type requires a specific crimp profile. Choose the right crimper based on whether you're working with insulated or non-insulated terminals.

4. How do you crimp without a crimping tool?

If you don't have a crimping tool, you can use a pair of scissors or a utility knife to cut away a section of the sheathing at the end of the cable. Untwist and arrange the small cables in the correct order, insert them into the appropriate connector, and use a small, flathead screwdriver to press down each of the pins.

5. What is stronger, a knot or a crimp?

A properly crimped terminal tackle is stronger than a knot. Crimped terminal tackles retain close to 100% of the lineweight, while a poorly tied knot can reduce the effective lineweight by half. Crimping provides a reliable and durable connection that is less likely to come apart when tested by big fish.

6. Can you crimp with normal pliers?

No, normal pliers cannot be used for crimping. They won't create the proper cold weld connection that a crimping tool can provide. A poor crimp can result in air and moisture getting inside the connection, leading to failure. It is recommended to invest in a specialized crimping tool for proper crimping.

7. Should you twist wires before crimping?

It is advised to lightly twist the wires before crimping, in the same direction as their original twist. However, when crimping multiple wires in a terminal, they should not be twisted together. Tensile testing for certification should only be performed on the smallest wire.

8. Do you crimp once or twice?

When using a long sleeve, it is recommended to crimp it at least twice, once each about 2 to 4 millimeters from the ends of the sleeve. However, with a short sleeve and a thick-jawed crimper, there is usually not enough room for two crimps, so a single crimp in the center is sufficient.
