Abstract
An electrical terminal assembly of the type adapted to extend through and be press fitted within an insulating terminal block. The assembly includes a cylindrical metal body having a coaxial cylindrical stem emerging from one end for securing one electrical circuit wire, and a captive screw post is adapted to cooperate coaxially with the metal body at its opposite end for securing another circuit wire. To trap the screw post, the body has a hollow bore which is blind at one end (proximal) the bore having an internally threaded section adjacent the proximal end, a larger unthreaded section extended therefrom almost to its open end (distal), and an unthreaded shoulder section at the distal end smaller than the diameters of both the threaded and unthreaded sections. The screw post has a shaft that fits into the bore and a slotted head located exterior of the bore. The post shaft includes a threaded section adjacent its proximal end dimensioned to cooperate with the threaded bore section, and a smaller unthreaded section extended between the threaded section and the slotted head. A helical spring is seated between the blind end of the bore and the proximal end of the post shaft which b…
