the fusite 13 is used as a specific example of a typical electrical connection or coupler used in wiring circuits between sets of wires to serve as a mechanical connection between said sets of wires prior to the present invention there were many exposed electrical connections that had to be hand wired and then extra parts added to protect and shield said exposed connections as can be seen from the prints the present invention electrically connects and shields a source of electricity to a compressor such as a refrigeration compressor with a minimum of parts and hand labor many times a refrigeration compressor is contained within a metal shell which has only the male connectors of the fusite 13 and sometimes a male stud extending from the top of the shell as shown in fig5 the slot 2 permits the preferred embodiment of the present invention the compressor plug with internal thermal overload protection 1 to be inserted around such a male stud 23 extending from the top 14 of a shell containing a refrigeration compressor in such an instance a nut or a nut with a washer secured to a threaded end on said male stud would hold the compressor plug with internal thermal overload protection 1 to the aforementioned top 14 the slot 2 is elongated so as to permit some.
