Barrel, Bullet Connectors
      
      Bullet connectors, also known as barrel connectors, are a simple single conductor solution to provide quick and reliable wire connections. The receptacle (socket) is a circular, hollow tube and the plug is a pin with a rounded end to easily connect with the female connector. They are available in a wide range of wire gauges, barrel lengths, and barrel diameters. These can be uninsulated or insulated, with multiple termination styles and contact finish options.
