What’s a Butt Splice Connector? And Why Do I Need One?
Despite its ambiguous name, the butt splice connector is actually a fairly common and useful connector used in electrical work. A butt splice connector is a form of so called “crimp” connectors. Crimp connectors are used to terminate wires safely, or connect one wire to another. The wire is inserted into the connector. Then the connector is “crimped”, usually with pliers. As a result, the connector is bent and deformed around the wire. This crimping forces the wire into contact with the metal inside the connector. The other end can either be crimped to terminate the wire. Alternatively the process can be repeated on the other side, with another wire, to connect two wires. The butt splice connector is simply a cylindrical crimp connector with one crimp on each end. 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.
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. For many applications, the butt splice connector holds considerable advantages over soldering. Butt splice connectors are cheap and easy to use. Soldering equipment takes much longer to set up and use. Butt splice connectors are also safer than soldering equipment, with no heat and no toxins. Overall, the butt splice connector is a great connector to have. It is safe, convenient, easy to use, and cheap.
If the butt splice connector sounds like a viable option for you, the next question is where to get them. Most hardware and electronics stores carry butt splice connectors. Frequently they’re sold in large value packs because of their versatility and low cost. Nelco Products offers butt splice connectors in packs of 100 or in a bulk package of 1,000. Despite its funny name, the butt splice connector is truly a vital electrical accessory that belongs in the toolbox of every electrician and hobbyist from DIY enthusiasts to the seasoned professional.
