    Wire Connector Types (Complete List for Beginners)

    Wire connectors help to connect two wires. Most importantly, connectors prevent the wires from being expired to metal surfaces. Moreover, wire connectors resist short circuits and electrical faults. 

    Not to mention, they are available in different colors, shapes, and sizes. However, based on the electrical project, you can choose the type of wire connector. Let’s explore different types of wire connectors and tools required for connecting the wires. 

     

    Twist-on wire connectors:

    Twist-on wire connectors are the simplest type of wire connectors. Moreover, they have external grooves or wings, which helps in easy handling. You can easily use and twist the connector by hand. 

    Strip the wires from the end, and place two wires together in a parallel direction. Once the wires are in place, slide the connector and twist it to make a connection. 

    If you wish to remove the connector, rotate it in an anti-clockwise direction and remove the wires. These connectors are color-coded and indicate the size of the wire. It is pretty easy to use the twist-on connector as compared to other connectors. 

     

    Push-in wire connectors:

    Push-in wire connectors can only be used with solid wires. You cannot use a stranded wire with a push-in wire connector. With the help of a wire stripper, remove the insulation of the wire. 

    However, make sure that you are not stripping more than ½ inch. Push the wire into the port deep enough; it should be properly fitted inside. The push-in wire connector is transparent; you can see the connection and spot any problem. 

     

    Crimp-on wire connectors:

    Crimp-on wire connectors are made out of steel or copper. Moreover, a crimping tool is a must if you are using a crimp-on wire connector to make a connection. Simply strip the wire and twist two ends together. 

    Slide the connector on the wire, and with the help of the crimping tool, make a secure connection. Unlike other connectors, the connection from the crimp-on wire connector is solid, and in case of removal, the connector needs to be completely cut off using a wire cutter. 

     

    Spade connectors:

    Spade connectors are also known as spade terminals/terminal blockers. Moreover, it is pretty easy to use the spade connector. 

    Such connectors also serve as blockers and block the unnecessary current floating in the wires. Not to mention, electricians and HVAC technicians also use these connectors to protect wires from high voltage. 

     

    T-tap wire connectors:

    IDC connectors (Insulation displacement connectors) are T-tap wire connectors. They are indeed beneficial connectors as they connect more than two wires in a single component.

    However, just make sure that the wires you are trying to connect are capable of passing current. If you are using an IDC connector to fasten copper wires, you will have to apply double pressure, as copper wires are not flexible. 

    It is quite challenging to take time out for calling electricians for minor issues. With a right-sized wire, connector, stripper, it is quite easy to make a strong electrical connection. Moreover, the wire connectors are safe to use, and they are environmentally friendly as well.
