Molded plug for a compressor
View Patent ↗A plug assembly for a compressor having a shell, a terminal body on the shell, and a conductor pin extending through the terminal body, wherein a connector body of the plug assembly includes a plurality of electrical receptacles for electrical communication with the conductor pin at least partially disposed within a fence disposed around the terminal body. The plug assembly may be formed of a thermoplastic or thermoset material having a tensile modulus between 9500 MPa and 18000 MPa, and/or about 30 percent glass fibers. At least one electrical receptacle may be housed by an inner core of the plug assembly for electrical communication with the conductor pin. An annular sealing member may be supported by an outer body of the plug assembly for sealingly engaging the fence.
1. A compressor comprising:
a shell;
a compression mechanism disposed within said shell;
a motor for actuating said compression mechanism;
a terminal body secured to the shell;
at least one conductor pin extending through said terminal body;
a fence disposed around said terminal body and secured to said shell;
a plug including at least one electrical receptacle for electrical communication with said conductor pin at least partially disposed within said fence, and having an inner core surrounded by an outer body, said outer body having an end cap, a connector body extending from said end cap and including an inner surface opposing and in contact with an outer surface of said inner core, and an annular flange extending from said inner surface, said inner core disposed between said end cap and said annular flange and contacting said inner surface of said connector body along an entire length of said inner surface located between said end cap and a surface of said annular flange that opposes and is substantially parallel to said end cap; and
an annular sealing member supported by said outer body for sealingly engaging said fence disposed at an end of said plug assembly that is at least partially disposed within said fence.
2. The compressor of claim 1 , wherein said outer body includes a circumferential groove for supporting said sealing member, said sealing member being separate and apart from said outer body.
3. The compressor of claim 1 , wherein said plug is flame resistant.
4. The compressor of claim 1 , wherein said sealing member is an O-ring.
5. The compressor of claim 1 , wherein at least one of said inner core and said outer body is formed from a material that includes glass fibers.
6. The compressor of claim 5 , wherein said material includes between 30 percent and 50 percent glass fibers.
7. The compressor of claim 1 , wherein said inner core is formed from a material that is operable to withstand a glow wire flammability index of 850 C.
8. The compressor of claim 1 , wherein each of said inner core and said outer body is formed from one of a thermoplastic material and a thermoset material.
9. A plug assembly for a compressor, comprising:
an inner core having an outer surface;
an outer body surrounding said inner core and having an end cap, a connector body extending from said end cap and including an inner surface opposing and in contact with said outer surface of said inner core, and an annular flange extending from said inner surface and defining a first surface formed substantially parallel to and opposing said end cap, a second surface formed substantially parallel to said end cap and disposed on an opposite side of said annular flange than said first surface, and a third surface extending substantially parallel to said inner surface and between said first surface and said second surface, said inner core opposing said third surface and terminating at said second surface;
at least one electrical receptacle housed by said inner core; and
an annular sealing member encircling said outer body.
10. The plug assembly of claim 9 , wherein at least one of said inner core and said outer body is formed from a material that is flame resistant.
11. The plug assembly of claim 9 , wherein said sealing member is an O-ring separate and apart from said outer body.
12. The plug assembly of claim 9 , wherein at least one of said inner core and said outer body is formed from a material that includes glass fibers.
13. The plug assembly of claim 12 , wherein said material includes between 30 percent and 50 percent glass fibers.
14. The plug assembly of claim 9 , wherein said inner core is formed from a material that is operable to withstand a glow wire flammability index of 850 C.
15. The plug assembly of claim 9 , wherein each of said inner core and said outer body is formed from one of a thermoplastic material and a thermoset material.
16. The plug assembly of claim 9 , wherein said inner core is spaced apart from said third surface.
17. The plug assembly of claim 9 , wherein said inner core is substantially flush with said second surface.
18. A compressor comprising:
a shell;
a compression mechanism disposed within said shell;
a motor for actuating said compression mechanism;
a terminal body secured to the shell;
at least one conductor pin extending through said terminal body;
a fence disposed around said terminal body and secured to said shell;
a plug including at least one electrical receptacle for electrical communication with said conductor pin at least partially disposed within said fence, and having an inner core surrounded by an outer body, said outer body having an end cap, a connector body extending from said end cap and including an inner surface opposing an outer surface of said inner core, and an annular flange extending from said inner surface and defining a first surface formed substantially parallel to and opposing said end cap, a second surface formed substantially parallel to said end cap and disposed on an opposite side of said annular flange than said first surface, and a third surface extending substantially parallel to said inner surface and between said first surface and said second surface, said inner core having a first surface in contact with said end cap and a second surface disposed on an opposite end of said inner core than said first surface of said inner core, said second surface of said inner core being substantially flush with said second surface of said annular flange; and
an annular sealing member supported by said outer body for sealingly engaging said fence disposed at an end of said plug assembly that is at least partially disposed within said fence.
19. The compressor of claim 18 , wherein said outer body includes a circumferential groove for supporting said sealing member, said sealing member being separate and apart from said outer body.
20. The compressor of claim 18 , wherein at least one of said inner core and said outer body is formed from a material that is flame resistant.
21. The compressor of claim 18 , wherein each of said outer body and said inner core is formed from one of a thermoplastic material and a thermoset material.
22. The compressor of claim 18 , wherein at least one of said inner core and said outer body is formed from a material that includes glass fibers.
