Abstract
Abstract An electrical connector for effecting connection between a wire and a `banana` type socket includes an axially extending male pin divided by a slot(s) into radially expansible contact arm quadrants. A terminal fastener is mounted in threaded engagement on the pin for securing an electrical terminal between the terminal fastener and an annular portion of the pin. An expander element is also mounted in threaded engagement on the pin and includes an expander rod having a frusto conical tip portion that enters and engages a tapered internal bore of the pin to permit the contact arm quadrants to be forced outward to grip the smooth internal bore of the `banana` type socket.
