摘要

The terminal clamp has a main block of insulating material in which there is a central metal support [20] having a pair of pivot mounting points [19] that receive cam shaped [11] elements that are used to release spring wire clamps [9]. Each element has a formed slot to allow insertion of a screwdriver tip [18]. This allows the element to be turned and so depresses the tip of the spring clamp so that the wire end [6] can be inserted The clamps is then returned to the initial position to apply contact force.
