What is a Binding Post?

Binding Post Description

Initially invented by the General Radio Corporation of Cambridge, MA, binding posts are commonly used in test fixtures for wire termination. A typical single post binding post consists of a cylindrical threaded stem with a drilled hole for accepting the conductor, one or more molded nuts, and an insulated cap. During installation the conductor (usually stripped copper wire) is inserted through a hole in the threaded stem of the post and tightened into place by using a molded nut. Binding post caps are used to insulate the binding post and come in 3 primary colors: red indicates an active (positive) terminal, black indicates an inactive (negative) terminal, and green indicates the ground terminal.

Binding Post Designs

One common design for binding posts is called a universal or five-way style. This style allows for the joining of multiple types of connectors such as banana plugs, pin connectors, uninsulated wire, and more. Other types of binding posts include insulated binding posts, dual binding posts, knob type binding posts, metal binding posts, miniature binding posts and spring loaded binding posts.

Product Spotlight: Pomona Banana Plugs and Jacks

Banana plugs are single conductor connectors used to carry DC and low-frequency signals and connect wires to equipment. Applications ranging from power supplies to multimeters typically use banana plugs. Standard banana plugs are only used for currents less than 33 volts since they have exposed metal parts. Sheathed banana plugs are rated for use with higher voltages, and are often used as multimeter test leads. Engineers and technicians use banana jacks on custom fixtures, early prototypes, and informal “one-off” projects.
