Abstract

A cathode ray tube display terminal includes a pluggable power supply. A recessed handle for removing the power supply from the CRT terminal is trapped by the AC line cord plug necessitating removal of the plug to permit access to the handle.

Claims

1. A cathode ray tube display terminal includes a power supply mounted to a chassis of said terminal by means of a slide, said power supply including connector fingers for engaging a fixed connector when said power supply is fully inserted into said fixed connector, said power supply being coupled to a power source through an electrical plug, said power supply comprising:

a molded plate having a plurality of openings;

a handle pivotally mounted to said molded plate within a first opening; and

an electrical receptacle accessible through said first opening for receiving said electrical plug for applying electrical power to said power supply, thereby trapping said handle between said molded plate and said electrical plug;

said handle being freed to pivot when said electrical plug is removed from said electrical receptacle for removing said electrical power from said power supply,

said handle being accessible for unplugging said power supply from said terminal.

2. The terminal of claim 1 wherein said molded plate includes a second opening for providing means for allowing a screw to fasten said power supply to said slide.

3. The terminal of claim 2 wherein said molded plate includes a third opening for making a power switch accessible for applying said electrical power to said power supply when said electrical plug provides said electrical power to said electrical receptacle.
