What is a Butt Splice?
Butt Splice Description
Despite their humorous name, butt splices are essential and widely utilized electrical connectors. In their most basic form butt splices are tubular metal connectors used to connect (splice) or terminate wire endings by crimping or soldering. Butt splice connectors may be used to repair damaged wiring, to increase overall wire length, to securely terminate wires, or to split from a single wire to multiple wires.
Although butt splices are available uninsulated many butt splices feature nylon or vinyl insulators that protect connections from environmental hazards and prevent short circuiting. In addition, most butt splice connectors utilize crimping thus eliminating the safety hazards and time constraints of soldering.
