Types of Electrical Connections: Crimp Connectors
Some of the different crimp connectors include:
- Male Disconnects
- Female Disconnects
- Bullet Plugs
- Bullet Receptacles
- Butt Splices
- Close Ends
When attaching the connectors, use the appropriate gauge wire and connector size. If you use a connector that is too large for the wire gauge, it will not make a good connection and is likely to slide off.
To attach your crimp connectors, strip ¼ inch of insulation from the end of the wire, insert into the crimp terminal, and crimp with a terminal crimping tool. Then finally, give your wire a firm pull while holding the terminal. This verifies a good connection.
Terminals are generally color coded to match up with the correct wire gauge. Here is a table displaying color codes for crimp connectors.

If you don't know what your wire's gauge size is, use a crimper/stripper tool to help you. Strip the insulation and determine the wire gauge. If you're still not sure about the exact wire gauge, use the smallest size crimp connector that fits the wire. Don't forget to pull on the wire and terminal to see if you made the connection correctly.
If the wire is too small for the connector, you can wrap strands of wire around it to make it thicker. This works great for thin wire and butt connections between two different gauge wires.
The disconnectable terminals mentioned are useful when disassembly is expected. Take the time to choose the right connectors for your task at hand.
