Terminal connection structure of motor incorporated within a compressor
View Patent ↗A terminal connection structure of a motor incorporated within a compressor for connecting feed terminals for a stator of a motor to the compressor includes a lid, which is attached to a compressor body portion for securing external feed terminals with a hermetic seal. The terminal connection structure is provided with a resin chamber on an inner surface of the lid, through which the external feed terminals extend, and a resin housing containing wire-side terminals, which are provided at ends of wires connected to the stator and which are connected to the external feed terminals. In the structure, superior insulation properties may be obtained even if the compressor size is reduced, and the productivity and assembling performance of the compressor may be improved.
1. A terminal connection structure of a motor incorporated within a compressor for connecting feed terminals for a stator of said motor to said compressor, said structure comprising:
a lid attached to a compressor body portion for securing external feed terminals with a hermetic seal, and provided with a resin chamber on an inner surface of said lid, through which said external feed terminals extend; and
a resin housing containing wire-side terminals, which are provided at ends of wires connected to said stator and which are connected to said external feed terminals, wherein at least a portion of said resin chamber extends radially toward an axis of said compressor, and said resin housing is disposed within said portion of said resin chamber.
2. The terminal connection structure of claim 1 , wherein further comprising a seal plate engaged to a circumferential groove on an interior surface of said cylindrical portion of said resin chamber, thereby enclosing said resin housing within said resin chamber.
3. The terminal connection structure of claim 1 , wherein at least the portion of said resin chamber that extends radially toward an axis of said compressor is cylindrical.
4. A compressor comprising a motor and a terminal connection structure of said motor for connecting feed terminals for a stator of said motor to said compressor, said structure comprising:
a lid attached to a compressor body portion for securing external feed terminals with a hermetic seal, and provided with a resin chamber on an inner surface of said lid, through which said external feed terminals extend; and
a resin housing containing wire-side terminals, which are provided at ends of wires connected to said stator and which are connected to said external feed terminals
wherein at least a portion of said resin chamber extends radially toward an axis of said compressor, and said resin housing is disposed within said portion of said resin chamber.
5. The compressor of claim 4 , wherein farther comprising a seal plate engaged to a circumferential groove on an interior surface of said cylindrical portion of said resin chamber, thereby enclosing said resin housing within said resin chamber.
6. The compressor of claim 4 , wherein at least the portion of said resin chamber that extends radially toward an axis of said compressor is cylindrical.
