Banana connectors are a popular species of electrical connectors which find major use in connecting power amplifiers, speakers, woofers etc. in audio systems. Designed for high power applications, these connectors are known to work at an average of 1000volts and 15amperes. In any audio set up, the connectors are color coded into red and black where red connector holds the live wire while the black one serves as a reference (ground). Except the color coding, there is no structural difference between the connectors. This Insight will give you a sneak-peek inside the assembly of such a connector, along with its external and internal details.
