HOW TO USE CRIMP TERMINALS CORRECTLY

Many times the Electrical issues is intermittent, where sometimes the circuit works, and sometimes it does not, meaning that you have to be able to track down the problem while it is not functioning. Most often, these issues are the result of a poor connection. Once you have the problem located, you need to fix it.

 

There are two ways to repair wires – solder and crimp terminals. Some scenarios require you to crimp wire terminals, such as modular terminal connections, and removable terminals, where others can be handled through either method. Soldering is usually the best method to splice two wires together, but that is not always feasible. Crimp terminals are very useful for long-lasting repairs, but they get a bad rap because of consistent poor installation. There are several different types of crimp terminals that require different tools, and they should always be sealed. We have compiled a list of tips and tricks for wire crimps. Use these, and you should never go wrong.  

 

Right Tool

Cheapo crimp tools are only good for giving you blood blister, they have no business being used on actual wire crimps. A good set of insulated/non-insulated wire crimpers will last you forever.  These are more expensive, but you can buy a master tool with interchangeable dies that will work for all types of terminals.

Correct Size

There is a correct size for every wire gauge and a correct crimping die to match. Insulated terminals are selected by a range of sizes noted by the color of the insulation. Any wire larger than 10-gauge requires a non-insulated terminal. These terminals usually come with a slip-on silicone insulating sleeve, but not always.

Practice Safe Stripping

Removing the insulation from wire requires a good pair of wire strippers. Some strippers require you to pull the wire through them, while others perform the entire task in one motion. The key to a good termination is just enough wire in the crimp, not too much, not too little. The end of the wire should be flush or just slightly extended through the end of the crimp.

 

Go All In

Don’t leave stragglers hanging outside the terminal. Make sure all of the wire makes it into the terminal. An easy way to do this to give the wire a couple of twists after stripping the insulation away.

 

 

No Half Measures

Fully crimp, but don’t over-crimp. It is hard to over-crimp a terminal, but it is possible, and the result is torn metal that breaks in half. The biggest issue is a half-crimp, where the crimp barrel is compressed, but not enough to seat the wire. The result of this is a loose connection that will cause all kinds of headaches and the wire can even come out. Always test your crimp by tugging on the wire and terminal. If it moves, cut it off and do it again.

 

Orientation

Only one side of the crimp should be compressed, and which side depends on the terminal. For open terminals, such as weather or Metri-pack terminals, the open legs get crimped. For all barrel-type terminals, the kind that makes a complete circle, the crimp indentation goes to the solid side, NOT where the two ends meet.
