The terminal assembly may engage the shell and may include an outwardly extending conductor and a terminal fence at least partially surrounding said conductor. The electronics module may include a back plate having an opening through which said terminal fence is received. The back plate may include flexible tabs and a spring element. The flexible tabs may removably engage the terminal fence. The spring element may contact the shell and bias the back plate away from the shell. The molded plug may engage the terminal fence and may engage the conductor for electrical communication between the conductor and the molded plug. ## Claims ### Claim 1 A compressor comprising: a shell; a terminal assembly engaging said shell and including an outwardly extending conductor and a terminal fence at least partially surrounding said conductor; an electronics module including a back plate having an opening through which said terminal fence is received, said back plate including flexible tabs and a spring element, said flexible tabs removably engaging said terminal fence, said spring element contacting said shell and biasing said back plate away from said shell; and a molded plug engaging said terminal fence and engaging said conductor for electrical communication between said conductor and said molded plug. ### Claim 2 (depends on 1) The compressor of claim 1, wherein said spring element includes a resiliently compressible annular gasket. ### Claim 3 (depends on 2) The compressor of claim 2, wherein said annular gasket seals against said shell and said back plate. ### Claim 4 (depends on 3) The compressor of claim 3, wherein said back plate includes an annular recess at least partially surrounding said opening, and wherein said annular gasket is at least partially received in said annular recess. ### Claim 5 (depends on 1) The compressor of claim 1, wherein said terminal fence includes a plurality of apertures, and said flexible tabs include barbs engaging said apertures. ### Claim 6 (depends on 5) The compressor of claim 5, wherein said spring element biases said barbs into engagement with edges of said apertures. ### Claim 7 (depends on 5) The compressor of claim 5, wherein said terminal fence is received between said flexible tabs. ### Claim 8 (depends on 7) The compressor of claim 7, wherein said molded plug is received within said terminal fence. ### Claim 9 (depends on 1) The compressor of claim 1, wherein said electronics module includes a cover removably attached to said back plate, and wherein said back plate and said cover cooperate to form an enclosure in which a plurality of electronic components are disposed. ### Claim 10 (depends on 9) The compressor of claim 9, wherein said electronics module includes one or more indicator lights extending through one or more apertures formed in said cover. ### Claim 11 (depends on 9) The compressor of claim 9, wherein said cover includes a plurality of sleeves through which wires connected to said molded plug extend. ### Claim 12 (depends on 11) The compressor of claim 11, wherein said sleeves and said wires extend through current transformers disposed between said cover and said back plate. ### Claim 13 (depends on 9) The compressor of claim 9, wherein said cover includes a recess in which said molded plug is disposed, and wherein said molded plug is disposed outside of said enclosure formed by said back plate and said cover. ### Claim 14 An electronics module comprising a back plate and an electronic component mounted to said back plate, said back plate including an opening receiving a terminal fence extending outward from a shell of a compressor, said back plate including flexible tabs and a spring element, said flexible tabs removably engaging said terminal fence, said spring element contacting said shell and biasing said back plate away from said shell. ### Claim 15 (depends on 14) The electronics module of claim 14, wherein said spring element includes a resiliently compressible annular gasket that seals against said shell and said back plate. ### Claim 16 (depends on 15) The electronics module of claim 15, wherein said back plate includes an annular recess at least partially surrounding said opening, and wherein said annular gasket is at least partially received in said annular recess. ### Claim 17 (depends on 14) The electronics module of claim 14, wherein said terminal fence includes a plurality of apertures, and said flexible tabs include barbs engaging said apertures, and wherein said spring element biases said barbs into engagement with edges of said apertures. ### Claim 18 (depends on 17) The electronics module of claim 17, wherein said terminal fence is received between said flexible tabs, and wherein a molded plug is received within said terminal fence, said molded plug in electrical communication with a conductor surrounded by said terminal fence. ### Claim 19 (depends on 18) The electronics module of claim 18, wherein said electronics module includes a cover removably attached to said back plate, and wherein said back plate and said cover cooperate to form an enclosure in which said electronic component is disposed. ### Claim 20 (depends on 19) The electronics module of claim 19, wherein said cover includes a recess in which said molded plug is disposed, and wherein said molded plug is disposed outside of said enclosure formed by said back plate and said cover.
