Abstract
An electrical feedthrough assembly for providing connection to components of a compressor. The electrical feedthrough assembly includes a housing having an inner surface defining a channel. A sealed wire assembly is provided in the channel. The sealed wire assembly includes a body having an outer surface defining a groove and a plurality of wires sealingly passing through the body. An o-ring fits in the groove to provide a hermetic seal between the body and the inner surface of the housing.
Claims19
An assembly for a compressor, the assembly comprising:
- a housing, the housing comprising a cylindrical wall, the cylindrical wall having an inner surface defining a passageway through the housing and an outer surface being connectable to a shell of a compressor;
- and
- a wire assembly being hermetically sealed within the housing, the wire assembly comprising:
- a body positioned in the passageway;
- a groove formed in the body;
- an o-ring positioned in the groove to contact the inner surface of the housing to form the hermetic seal;
- and
- a plurality of wires embedded in the body, each wire of the plurality of wires being hermetically sealed by the body.
A compressor comprising:
- a shell, the shell having an opening;
- and an assembly positioned in the opening, the assembly comprising:
- a housing, the housing comprising a cylindrical wall, the cylindrical wall having an inner surface defining a passageway through the housing and an outer surface being connected to the shell, the connection between the outer surface of the cylindrical wall and the shell providing a hermetic seal between the cylindrical wall and the shell;
- a body positioned in the passageway and being hermetically sealed within the housing, the hermetic seal between the body and the housing being formed from a compression fit of the body into the housing;
- at least one groove formed in the body;
- at least one O-ring positioned in the at least one groove to contact the housing to form the hermetic seal;
- and a plurality of wires embedded in the body, each wire of the plurality of wires being hermetically sealed by the body.
A method for assembling a feedthrough assembly in a shell of a compressor, the method comprising:
- connecting an outer surface of a cylindrical housing into an opening in a shell of a compressor, the connection between the outer surface of the cylindrical housing and the shell providing a hermetic seal between the cylindrical housing and the shell, the cylindrical housing having an elongated inner surface defining a channel;
- embedding at least one wire in a body, the embedded at least one wire being hermetically sealed by the body;
- placing an o-ring in a respective groove in the body;
- and
- disposing the body within the cylindrical housing such that the placed o-ring forms a hermetic seal with the cylindrical housing.
