Overall, the butt splice connector is a great connector to have. Butt splice connectors are also safer than soldering equipment, with no heat and no toxins. Soldering equipment takes much longer to set up and use. Butt splice connectors are cheap and easy to use. For many applications, the butt splice connector holds considerable advantages over soldering. Given its simple design and purpose, why should you use a butt splice connector? Typically, crimp connectors and soldering are two common methods of connecting wires. Some butt splice connectors are manufactured with heat shrinking ends which contract around the wire when exposed to heat, leading to a better seal between the wire and butt splice connector. The butt splice connector is simply a cylindrical crimp connector with one crimp on each end.

Alternatively the process can be repeated on the other side, with another wire, to connect two wires. The other end can either be crimped to terminate the wire. This crimping forces the wire into contact with the metal inside the connector. As a result, the connector is bent and deformed around the wire. Then the connector is “crimped”, usually with pliers. Crimp connectors are used to terminate wires safely, or connect one wire to another. A butt splice connector is a form of so called “crimp” connectors.
