[0048] Hereinafter, embodiments according to the present invention will be described in detail with reference to the attached drawings.

[0049] FIG. 1 is a schematic drawing illustrating an air conditioner including a compressor according to one embodiment of the present disclosure.

[0050] Referring to FIG. 1, according to one embodiment of the present disclosure, a compressor (100), a condenser (10), an expansion device (20), and an evaporator (30) may be included in a refrigeration cycle device. For example, the refrigeration cycle device may include a refrigerant circulation circuit for exchanging heat through a refrigerant. For example, the refrigeration cycle device may include an air conditioner (1).

[0051] The compressor (100) may be configured to compress refrigerant gas. The compressor (100) may be configured to discharge high-temperature, high-pressure refrigerant gas. The gaseous refrigerant compressed to high temperature and high pressure in the compressor (100) may pass through the condenser (10), the expansion device (20), and the evaporator (30) and then flow back into the compressor (100).

[0052] The condenser (10) may be configured to exchange heat with air from the high-temperature and high-pressure refrigerant gas discharged from the compressor (100) in a high-temperature and high-pressure state. The condenser (10) may condense the refrigerant gas in a high-temperature and high-pressure state, and the refrigerant condensed while passing through the condenser (10) may release heat to the outside.

[0053] The expansion device (20) may be configured to expand the refrigerant discharged from the condenser (10). For example, the expansion device (20) may be configured to expand the refrigerant liquid in a high temperature and high pressure state using a throttling effect. The density and pressure of the refrigerant may be reduced by the expansion device (20), and the expansion device (20) may discharge the refrigerant liquid in a low temperature and low pressure state. The expansion device (20) may include an orifice that can reduce the cross-sectional area of ​​the flow path. As the refrigerant passes through the expansion device (20), it may become a saturated vapor state with reduced pressure to a state where it is easy to evaporate in the evaporator (30).

[0054] The evaporator (30) may be configured to exchange heat with air for the low-temperature and low-pressure liquid refrigerant flowing in from the expansion device (20). The evaporator (30) may evaporate the low-temperature and low-pressure refrigerant, and the refrigerant evaporating as it passes through the evaporator (30) may absorb external heat.

[0055] The low-temperature and low-pressure refrigerant gas discharged from the evaporator (30) can be fed back into the compressor (100) and compressed.

[0056] Oil may be provided inside the compressor (100) to ensure smooth operation of the compressor (100). The oil can improve the energy efficiency of the compressor (100) by reducing friction generated during operation of the compressor (100). The oil may be placed inside the housing (103, see FIG. 2) of the compressor (100).

[0057] However, some of the oil may be mixed with the refrigerant compressed by the compressor (100) and discharged outside the compressor (100). If the oil mixed with the refrigerant in this way flows into the condenser (10) or evaporator (30), the heat exchange efficiency of the condenser (10) and evaporator (30) may be reduced.

[0058] Accordingly, according to one embodiment, the refrigeration cycle device may further include an oil separator (40). The oil separator (40) may be provided to separate oil from the oil-mixed refrigerant discharged from the compressor (100). The oil in a liquid state separated from the oil separator (40) may be guided back to the compressor (100). The refrigerant in a gaseous state separated from the oil separator (40) may be guided back to the compressor (100).

[0059] FIG. 2 is a drawing illustrating a compressor and an oil separator according to one embodiment of the present disclosure.

[0060] Referring to FIG. 2, a compressor (100) according to one embodiment of the present disclosure may include a housing (103). Inside the housing (103), a receiving space may be formed to accommodate various parts of the compressor (100), such as a fixed scroll (111), a rotating scroll (112), a motor (70), and a rotating shaft (60). Oil may also be provided inside the housing (103) to reduce friction between the parts of the compressor (100). The housing (103) may form the exterior of the compressor (100).

[0061] The housing (103) may include a housing body (104), an upper cap (105) mounted on the upper part of the housing body (104), and a lower cap (106) mounted on the lower part of the housing body (104). For example, the housing body (104) may have a cylindrical shape with the top and bottom ends open, and the upper cap (105) and the lower cap (106) may be attached to the top and bottom ends of the housing body (104), respectively, to seal the interior of the housing (103).

[0062] The housing (103) may include an intake pipe (101) provided for refrigerant to flow in. The housing (103) may include an exhaust pipe (102) provided for refrigerant to be discharged.

[0063] The compressor (100) may include a fixed scroll (111) and a pivot scroll (112) arranged to compress a refrigerant. The fixed scroll (111) may be fixed inside the housing (103). The pivot scroll (112) may be arranged to pivot relative to the fixed scroll (111). The compressor (100) may include a motor (70) arranged to drive the pivot scroll (112).

[0064] The fixed scroll (111) may include a first plate (114) in the shape of a disc and a fixed wrap (116) that extends downward from the first plate (114) and forms a compression chamber (113) together with a pivot wrap (117) to be described later.

[0065] The rotating scroll (112) may include a second plate (115) in the shape of a disc that is positioned to face the first plate (114), and a rotating wrap (117) that extends upward from the second plate (115) and forms a compression chamber (113) together with a fixed wrap (116).

[0066] The fixed wrap (116) of the fixed scroll (111) and the pivot wrap (117) of the pivot scroll (112) can interlock to form a compression chamber (113). The compression chamber (113) is formed by the fixed scroll (111) and the pivot scroll (112), and as the pivot scroll (112) pivots relative to the fixed scroll (111), the volume of the compression chamber (113) can be reduced. As a result, the refrigerant sucked into the compression chamber (113) can be compressed.

[0067] The refrigerant that flows into and is compressed in the compression chamber (113) becomes a high-temperature and high-pressure refrigerant and can be discharged to the outside of the housing (103). According to one embodiment, the compressor (100) may include a first discharge chamber (110) and a second discharge chamber (120) through which the compressed refrigerant is discharged.

[0068] The compressor (100) may include a main frame (130) arranged to partition the first discharge chamber (110) and the second discharge chamber (120).

[0069] Between the rotating scroll (112) and the main frame (130), an Oldham ring (131) that rotates the rotating scroll (112) without rotating it may be provided.

[0070] A main frame (130) and a sub frame (126) are fixed to the upper and lower parts of the interior of the housing (103), respectively, and a motor (70) can be placed between the main frame (130) and the sub frame (126).

[0071] The compressor (100) may include a rotating shaft (60) configured to rotate by a motor (70). The rotating shaft (60) may be configured to connect the motor (70) and the rotating scroll (112) to transmit power from the motor (70) to the rotating scroll (112).

[0072] The rotating shaft (60) may include a main shaft (61) that is fitted into the motor (70) to rotate together with the motor (70), and an eccentric part (62) that is provided on the upper part of the main shaft (61) and has an eccentric axis that is eccentric from the axis of the main shaft (61).

[0073] The rotating shaft (60) is mounted between the main frame (130) and the sub-frame (126) and can transmit rotational force generated from the motor (70) to the rotating scroll (112).

[0074] The rotating shaft (60) may include an oil groove (63) that guides oil from an oil storage unit (125) provided at the bottom of the compressor (100) to the compression chamber (113).

[0075] According to one embodiment, the compressor (100) may further include three holes (118, 121, 123) and connecting parts (119, 122, 124) connected thereto, in addition to the suction pipe (101) and the discharge pipe (102).

[0076] The compressor (100) may include a first hole (118) formed in the first discharge chamber (110). The compressor (100) may include a first connecting part (119) inserted into the first hole (118). According to one embodiment, the first connecting part (119) may be provided to be inserted into the first hole (118), but alternatively, the first connecting part (119) may be formed integrally with the housing (103) (e.g., the housing body (104)). The first discharge chamber (110) and the outside of the compressor (100) may be connected through the first hole (118) and the first connecting part (119). Additionally, the oil separator (40) and the first discharge chamber (110) may be connected by connecting one end of the first pipe (51) to the first connecting part (119).

[0077] The compressor (100) may include a second hole (121) formed in the second discharge chamber (120). The compressor (100) may include a second connecting part (122) inserted into the second hole (121). According to one embodiment, the second connecting part (122) may be provided to be inserted into the second hole (121), but alternatively, the second connecting part (122) may be formed integrally with the housing (103) (e.g., housing body (104)). The second discharge chamber (120) and the outside of the compressor (100) may be connected through the second hole (121) and the second connecting part (122). Additionally, the oil separator (40) and the second discharge chamber (120) may be connected by connecting one end of the second pipe (52) to the second connecting part (122).

[0078] The compressor (100) may include a third hole (123) formed in the second discharge chamber (120). Additionally, the compressor (100) may include a third connecting part (124) inserted into the third hole (123). The third connecting part (124) may be provided to be inserted into the third hole (123), but alternatively, it may be formed integrally with the housing (103) (e.g., housing body (104)). The second discharge chamber (120) and the outside of the compressor (100) may be connected through the third hole (123) and the third connecting part (124). Additionally, the oil separator (40) and the second discharge chamber (120) may be connected by connecting one end of the third pipe (53) to the third connecting part (124).

[0079] The first discharge chamber (110) can be connected to the suction pipe (101) and the first pipe (51). The refrigerant introduced through the suction pipe (101) can be compressed in the compression chamber (113) and then discharged to the oil separator (40) through the first pipe (51). During the process of compressing the refrigerant, oil can be mixed with the refrigerant. Accordingly, the refrigerant mixed with oil can be discharged from the compression chamber (113) to the oil separator (40) through the first pipe (51).

[0080] The refrigerant and oil separated in the oil separator (40) can be recovered to the compressor (100) through the second pipe (52) and the third pipe (53), respectively. The refrigerant gas in a high temperature and high pressure state can be introduced into the second discharge chamber (120) through the second pipe (52) and guided to the condenser (10) through the discharge pipe (102).

[0081] The high-temperature oil separated from the oil separator (40) can be introduced into the second discharge chamber (120) through the third pipe (53) connected to the third connection part (124) and can be guided to the oil storage part (125) provided at the bottom of the compressor (100).

FIG. 7 is a cross-sectional view illustrating a combined view of one external terminal among a plurality of external terminals and one internal terminal among a plurality of internal terminals of a compressor according to one embodiment of the present disclosure.

[0085] Referring to FIGS. 3 to 7, a compressor (100) according to one embodiment of the present disclosure may include an external terminal (200) and an internal terminal (300) for applying power to a motor (70). The external terminal (200) and the internal terminal (300) may each include various conductive materials such as metal. The external terminal (200) and the internal terminal (300) may each be referred to as a "first terminal" and a "second terminal," respectively.

[0086] The external terminal (200) may be connected to an external power source located outside the housing (103). The external power source may include various external power devices for supplying power to various parts of the compressor (100). The external terminal (200) may be electrically connected to the external power source and may penetrate the housing (103) so that at least a portion thereof may be located inside the housing (103).

[0087] The internal terminal (300) can be placed inside the housing (103). The internal terminal (300) can be electrically connected to the motor (70). The internal terminal (300) can be electrically connected to the motor (70) through wires, etc.

[0088] The internal terminal (300) can be connected to the external terminal (200). The internal terminal (300) and the external terminal (200) can be connected by being joined together. As the internal terminal (300) and the external terminal (200) are connected to each other, power from an external power source can be supplied to the motor (70).

[0089] The external terminal (200) may include a plurality of external terminals (200). The plurality of external terminals (200) may be spaced apart from each other and may have an electrically insulated state.

[0090] Correspondingly, the internal terminal (300) may include a plurality of internal terminals (300). The plurality of internal terminals (300) may be spaced apart from each other and may have an electrically insulated state.

[0091] A plurality of external terminals (200) and a plurality of internal terminals (300) may be arranged to be connected to each other in a corresponding manner. The number of external terminals (200) and internal terminals (300) may be equal to each other and may be connected in a one-to-one correspondence. That is, each of the plurality of external terminals (200) may be connected to a corresponding internal terminal (300) among the plurality of internal terminals (300), and each of the plurality of internal terminals (300) may be connected to a corresponding external terminal (200) among the plurality of external terminals (200). The plurality of external terminals (200) and the plurality of internal terminals (300) may be combined in a one-to-one correspondence.

[0092] According to one embodiment, the compressor (100) may include three external terminals (200) connected to an external power source and three internal terminals (300) connected to a motor (70). Thus, three-phase AC power can be applied to the motor (70).

[0093] Each of the plurality of external terminals (200) may include an external terminal lead (210). For example, one external terminal (200) may include one external terminal lead (210). The external terminal lead (210) may be connected to an external power source.

[0094] At least a portion of the external terminal lead (210) may be positioned inside the housing (103). For example, a portion of the external terminal lead (210) may be positioned inside the housing (103) and another portion may be positioned outside the housing (103) so as to be connected to an external power source by penetrating the housing (103). Alternatively, for example, the entire external terminal lead (210) may be positioned inside the housing (103) and connected to an external power source by being connected to other components, such as wires or conductive pins, that are positioned outside the housing (103).

[0095] For example, the external terminal lead (210) may have a roughly long bar shape.

[0096] Each of the plurality of external terminals (200) may include a connecting plate (220). For example, one external terminal (200) may include one connecting plate (220). The connecting plate (220) may be connected to an external terminal lead (210). The connecting plate (220) may be coupled to an external terminal lead (210). The connecting plate (220) may be supported by the external terminal lead (210).

[0097] For example, the connecting plate (220) may have the shape of a plate having a thin thickness. For example, the connecting plate (220) may have a thin thickness in the direction in contact with the external terminal lead (210).

[0098] The external terminal lead (210) may come into contact with one side of the connection plate (220). The external terminal lead (210) may be coupled to one side of the connection plate (220). Here, one side of the connection plate (220) may refer, for example, to one side of the two sides in the direction in which the thickness of the connection plate (220) is thin.

[0099] The connecting plate (220) can be connected to the internal terminal (300). Each connecting plate (220) of the plurality of external terminals (200) can be connected to the corresponding internal terminal (300) among the plurality of internal terminals (300). Each connecting plate (220) of the plurality of external terminals (200) can be coupled to the corresponding internal terminal (300) among the plurality of internal terminals (300). Thus, the connecting plate (220) can connect the internal terminal (300) and the external terminal lead (210).

[0100] Each of the plurality of internal terminals (300) may include an internal terminal lead (310). For example, one internal terminal (300) may include one internal terminal lead (310). The internal terminal lead (310) may be electrically connected to the motor (70). The internal terminal lead (310) may be electrically connected to the motor (70) through components such as wires.

[0101] The internal terminal lead (310) can be placed inside the housing (103).

[0102] For example, the internal terminal lead (310) may have a roughly long bar shape.

[0103] Each of the plurality of internal terminals (300) may include a terminal holder (320). For example, one internal terminal (300) may include one terminal holder (320). The terminal holder (320) may be connected to an internal terminal lead (310). The terminal holder (320) may be coupled to the internal terminal lead (310). For example, the terminal holder (320) may be coupled by wrapping around a portion of the outer surface of the internal terminal lead (310). For example, the terminal holder (320) may be coupled to one end of the internal terminal lead (310). For example, the internal terminal lead (310) may be coupled to one end of the terminal holder (320).

[0104] The terminal holder (320) can be connected to the connection plate (220). The terminal holder (320) can be coupled to the connection plate (220). Each terminal holder (320) of a plurality of internal terminals (300) can be coupled to the connection plate (220) of the corresponding external terminal (200) among the plurality of external terminals (200).

[0105] According to one embodiment, the connecting plate (220) can be fitted into and coupled with the terminal holder (320). The connecting plate (220) can be coupled with the terminal holder (320) by being inserted into the terminal holder (320). When the terminal holder (320) and the connecting plate (220) are coupled, the terminal holder (320) may be provided to press both sides of the connecting plate (220). Here, the two sides of the connecting plate (220) may refer, for example, to the two sides of the connecting plate (220) in the direction of thinness. Here, the two sides of the connecting plate (220) may refer, for example, to the two sides of the connecting plate (220) in the direction of coupling with the external terminal lead (210).

[0106] For example, referring to FIGS. 6 and 7, the terminal holder (320) may include a first contact portion (321) and a second contact portion (322) that contact both sides of the connection plate (220). The first contact portion (321) may contact one side of the connection plate (220), and the second contact portion (322) may contact the other side of the connection plate (220). The first contact portion (321) may press one side of the connection plate (220), and the second contact portion (322) may press the other side of the connection plate (220). For example, the second contact portion (322) may contact the side of the connection plate (220) that is coupled with the external terminal lead (210), and the first contact portion (321) may contact the other side of the connection plate (220) opposite to it.

[0107] The first contact portion (321) may have a roughly flat plate shape that contacts one side of the connecting plate (220). The second contact portion (322) may have a curved shape that extends from the edge of the first contact portion (321) and contacts the other side of the connecting plate (220). For example, the second contact portion (322) may be provided in multiple numbers, and each of the second contact portions (322) may extend from both edges of the connecting plate (220). For example, each of the second contact portions (322) may extend from both edges of the first contact portion (321) in a direction perpendicular to the direction in which the connecting plate (220) is fitted into the terminal holder (320).

[0108] The connecting plate (220) can be combined with the terminal holder (320) by being inserted into the space between the first contact portion (321) and the second contact portion (322).

[0109] With this structure, the connecting plate (220) can be fitted into the terminal holder (320), and the connecting plate (220) and the terminal holder (320) can be firmly joined to each other.

[0110] According to one embodiment, in order for the connecting plate (220) and the terminal holder (320) to be more firmly joined to each other, the connecting plate (220) may include an irregularity (221) formed on the surface in contact with the terminal holder (320). For example, the connecting plate (220) may have an irregularity (221) on one surface in contact with the first contact portion (321).

[0111] Alternatively, according to one embodiment, the terminal holder (320) may include irregularities formed on the surface in contact with the terminal holder (320). For example, irregularities may be formed on the side in contact with the connecting plate (220) of the first contact portion (321).

[0112] With the structure of the connecting plate (220) and the terminal holder (320) as described above, the internal terminal (300) and the external terminal (200) can be firmly connected to each other.

[0113] The connecting plate (220) and the terminal holder (320) can be connected to each other only in a certain direction. When the connecting plate (220) and the terminal holder (320) are connected to each other, their positions to each other may be constant. For example, the connecting plate (220) and the terminal holder (320) can be connected to each other only in a direction in which the first contact portion (321) contacts a specific side of the connecting plate (220) and the second contact portion (322) contacts a specific other side of the connecting plate (220). For example, when the connecting plate (220) and the terminal holder (320) are connected, the external terminal lead (210) may be located between a plurality of second contact portions (322), and if the connecting plate (220) is to be connected to the terminal holder (320) in the opposite direction, the first contact portion (321) may interfere with the external terminal lead (210), and thus the connecting plate (220) and the terminal holder (320) may not be connected to each other.

[0114] The connecting plate (220) can be fitted on a side different from the one side to which the internal terminal lead (310) of the terminal holder (320) is connected. The internal terminal lead (310) can be coupled to the terminal holder (320) on a side opposite to the side to which the connecting plate (220) is fitted.

[0115] For example, the terminal holder (320) may extend from one end of the internal terminal lead (310) in a direction different from the direction in which the internal terminal lead (310) extends. For example, the terminal holder (320) may extend from one end of the internal terminal lead (310) in a direction perpendicular to the direction in which the internal terminal lead (310) extends. However, the present disclosure is not limited thereto, and in various embodiments, the relationship between the extension direction of the terminal holder (320) and the extension direction of the internal terminal lead (310) may be provided in various ways. For example, the terminal holder (320) may extend from one end of the internal terminal lead (310) in a direction parallel to the direction in which the internal terminal lead (310) extends.

[0116] The internal terminal (300) may be referred to as a "flag terminal," and the terminal holder (320) may be referred to by various terms such as "flag (part)."

[0117] A plurality of external terminals (200) can be fixed to the housing (103). For example, a plurality of external terminals (200) can be supported by an external terminal supporter (250) coupled to the outer wall of the housing (103), thereby being fixed to the housing (103). A plurality of external terminals (200) can be connected to an external power source and each of a plurality of internal terminals (300) by passing through the external terminal supporter (250). For example, the external terminal lead (210) of each of the plurality of external terminals (200) can pass through the external terminal supporter (250).

[0118] A plurality of internal terminals (300) can be supported by a plurality of external terminals (200) fixed to the housing (103) by being coupled to a plurality of external terminals (200).

[0119] According to one embodiment, the compressor (100) may include a terminal case (400). The terminal case (400) may be disposed inside the housing (103). The terminal case (400) may support a plurality of internal terminals (300). The terminal case (400) may cover a plurality of internal terminals (300). The terminal case (400) may accommodate a plurality of internal terminals (300).

[0120] Each terminal holder (320) of a plurality of internal terminals (300) can be placed inside a terminal case (400). The terminal case (400) can cover each terminal holder (320) of a plurality of internal terminals (300).

[0121] When the terminal holder (320) and the connection plate (220) are combined, the connection plate (220) can be placed inside the terminal case (400). When the terminal holder (320) and the connection plate (220) are combined, the terminal case (400) can cover the connection plate (220). The connection plate (220) of each of the plurality of external terminals (200) and the terminal holder (320) of each of the plurality of internal terminals (300) can be combined with each other inside the terminal case (400).

[0122] Thus, the terminal case (400) can protect the plurality of external terminals (200) and the plurality of internal terminals (300) from the high temperature inside the housing (103) during compressor (100) operation or foreign substances inside the housing (103) (e.g., oil, refrigerant, dust, metal powder coming from parts of the compressor (100), etc.).

[0123] Below, the structure and function of the terminal case (400) will be described in more detail.

[0124] FIG. 8 is a disassembled view illustrating the internal terminals and terminal case of a compressor according to one embodiment of the present disclosure. FIG. 9 is a disassembled view illustrating the case body and case cover of the terminal case of a compressor according to one embodiment of the present disclosure. FIG. 10 is a view illustrating the case body of a compressor according to one embodiment of the present disclosure as seen from one direction. FIG. 11 is a view illustrating the case body of a compressor according to one embodiment of the present disclosure as seen from another direction. FIG. 12 is a cross-sectional view illustrating a plurality of external terminals and a plurality of internal terminals of a compressor according to one embodiment of the present disclosure combined within the terminal case.

[0125] Referring to FIGS. 8 through 12, the terminal case (400) may include a guide hole (411). The guide hole (411) may be provided so that a terminal holder (320) included in each of the plurality of internal terminals (300) is inserted. The guide hole (411) may be provided so that a connecting plate (220) included in each of the plurality of external terminals (200) is inserted. For example, the terminal holder (320) may be inserted from one side of the guide hole (411), and the connecting plate (220) may be inserted from the other side of the guide hole (411).

[0126] By inserting the terminal holder (320) into the guide hole (411), the internal terminal (300) can be coupled to the terminal case (400). By inserting the connecting plate (220) into the guide hole (411), the external terminal (200) can be coupled to the terminal case (400).

[0127] Guide holes (411) may be provided in multiple numbers. In each of the multiple guide holes (411), a connection plate (220) of one of the multiple external terminals (200) and a terminal holder (320) of one of the multiple internal terminals (300) may be inserted. The number of guide holes (411) may be equal to the number of external terminals (200) and the number of internal terminals (300), and for example, the terminal case (400) may include three guide holes (411).

[0128] One side in which the terminal holder (320) of each of the plurality of internal terminals (300) is inserted into each of the plurality of guide holes (411) may be identical to each other. The other side in which the connecting plate (220) of each of the plurality of external terminals (200) is inserted into each of the plurality of guide holes (411) may be identical to each other.

[0129] Guide holes (411) may be provided so that the connecting plate (220) and the terminal holder (320) can be coupled to each other within the terminal case (400). Multiple guide holes (411) may guide the terminal holder (320) so that the terminal holder (320) of each of the multiple internal terminals (300) is inserted. Multiple guide holes (411) may guide the connecting plate (220) so that the connecting plate (220) of each of the multiple external terminals (200) is inserted and coupled to the terminal holder (320) within the guide holes (411).

[0130] As the connecting plate (220) and the terminal holder (320) are joined together within the guide hole (411) formed inside the terminal case (400) in this manner, the connecting plate (220) and the terminal holder (320) can be efficiently protected from external high temperatures or foreign substances.

[0131] The terminal case (400) may include inclined surfaces (415, 416) provided around the guide hole (411). The inclined surfaces (415, 416) may be provided to guide the insertion of the terminal holder (320) and the connecting plate (220), respectively.

[0132] The terminal case (400) may include a first inclined surface (415) formed on the side in which the terminal holder (320) is inserted into the guide hole (411). The first inclined surface (415) of the guide hole (411) may be formed on the side adjacent to the case cover (420) described later. The first inclined surface (415) may be formed such that the width of the guide hole (411) narrows as it faces the direction in which the terminal holder (320) is inserted into the guide hole (411). The first inclined surface (415) may guide the terminal holder (320) to be inserted into the guide hole (411), and a portion of the terminal holder (320) inserted into the guide hole (411) after passing the inclined surface (415) may be more firmly supported and fixed by the terminal case (400) within the guide hole (411).

[0133] The terminal case (400) may include a second inclined surface (416) formed on the side in which the connecting plate (220) is inserted into the guide hole (411) (see FIG. 4). The second inclined surface (416) of the guide hole (411) may be formed on the side adjacent to the inner wall of the housing (103). The second inclined surface (416) may be formed such that the width of the guide hole (411) becomes narrower as it faces the direction in which the connecting plate (220) is inserted into the guide hole (411). The second inclined surface (416) may guide the insertion of the connecting plate (220) into the guide hole (411).

[0134] Multiple guide holes (411) can be partitioned from one another. Thus, terminal holders (320) and connecting plates (220) inserted into different guide holes (411) can be spaced apart from each other, and a short circuit caused by contact between terminals inserted into different guide holes (411) can be efficiently prevented.

[0135] According to one embodiment, each of the plurality of guide holes (411) may be spaced apart from the central axis (401) of the terminal case (400). For example, each of the plurality of guide holes (411) may be spaced apart from the positioning hole (402) described later, which is provided on the central axis (401) of the terminal case (400). The central axis (401) of the terminal case (400) may be defined as an axis passing through the center of the terminal case (400) in the direction in which the terminal holder (320) and the connecting plate (220) are inserted into the guide hole (411).

[0136] According to one embodiment, the terminal holder (320) can be fixed within the guide hole (411). The guide hole (411) can be formed to prevent the terminal holder (320) from moving within the guide hole (411). Within the guide hole (411), the terminal holder (320) can be prevented from moving by contacting the inner surface of the terminal case (400) in at least two directions. Thus, the terminal holder (320) and the connecting plate (220) can be easily combined simply by inserting the connecting plate (220) into the guide hole (411) into which the terminal holder (320) is inserted.

[0137] In this way, a plurality of guide holes (411) are formed in the terminal case (400), and a terminal holder (320) is inserted and fixed in each of the plurality of guide holes (411). A connection plate (220) of each of the plurality of external terminals (200) can be inserted into the corresponding guide hole (411) and guided to be coupled to the terminal holder (320) inserted therein. Thus, it is possible to combine the plurality of external terminals (200) and the plurality of internal terminals (300) simultaneously, and the combining process can be performed easily and efficiently. Furthermore, as described in FIGS. 13 and 14, the process of combining the plurality of external terminals (200) and the plurality of internal terminals (300) can be easily automated.

[0138] According to one embodiment, when the connecting plate (220) is inserted into the guide hole (411), at least a portion of the external terminal lead (210) may also be inserted into the guide hole (411). For example, the external terminal lead (210) may be inserted into the guide hole (411) by penetrating one side adjacent to the housing (103) of the terminal case (400).

[0139] According to one embodiment, an internal terminal lead (310) may penetrate a terminal case (400). The terminal case (400) may include an internal terminal lead hole (430) that is penetrated by the internal terminal lead (310). The internal terminal lead hole (430) may be connected to a guide hole (411). The guide hole (411) may extend from the internal terminal lead hole (430).

[0140] For example, an internal terminal lead hole (430) may be formed in the case body (410) described later. The internal terminal lead hole (430) may be formed on the periphery of the case body (410). Here, the periphery of the case body (410) may include a periphery of the case body (410) facing a direction different from the direction in which the terminal holder (320) and the connecting plate (220) are inserted.

[0141] The internal terminal lead hole (430) may extend in one direction from the periphery of the case body (410) toward the inside of the case body (410). The guide hole (411) may extend from the inner end of the internal terminal lead hole (430), and the direction in which the internal terminal lead hole (430) extends from the periphery of the case body (410) and the direction in which the guide hole (411) extends from the internal terminal lead hole (430) may be perpendicular to each other. For example, the direction in which the internal terminal lead hole (430) extends from the periphery of the case body (410) and the direction in which the guide hole (411) extends from the internal terminal lead hole (430) may be approximately perpendicular.

[0142] The terminal case (400) may include a number of internal terminal lead holes (430) corresponding to the number of external terminals (200) (e.g., 3). For example, a plurality of internal terminal lead holes (430) may be spaced apart and partitioned from each other.

[0143] According to one embodiment, the terminal case (400) may include a case body (410) and a case cover (420).

[0144] The case body (410) may be provided to support a plurality of internal terminals (300). Guide holes (411) may be formed in the case body (410). That is, a plurality of guide holes (411) may be formed in the case body (410).

[0145] A plurality of guide holes (411) may extend from one side adjacent to the case cover (420) of the case body (410) to the other side. A terminal holder (320) may be inserted on the side adjacent to the case cover (420), and a connecting plate (220) may be inserted on the opposite side.

[0146] The case cover (420) can cover the case body (410). The case cover (420) can cover the case body (410) from one side. The case cover (420) can cover a plurality of guide holes (411). The case cover (420) can cover each terminal holder (320) of a plurality of internal terminals (300).

[0147] The case cover (420) can cover the case body (410), the plurality of guide holes (411), and the terminal holder (320) of each of the plurality of internal terminals (300) on one side where the terminal holder (320) is inserted into the plurality of guide holes (411). The case cover (420) can cover the case body (410), the plurality of guide holes (411), and the terminal holder (320) of each of the plurality of internal terminals (300) on the side opposite to the inner wall of the housing (103). The case cover (420) can cover the case body (410), the plurality of guide holes (411), and the terminal holder (320) of each of the plurality of internal terminals (300) on the side opposite to the connecting plate (220).

[0148] The case cover (420) can also cover at least a portion of the internal terminal leads (310) of each of the multiple internal terminals (300).

[0149] The case cover (420) can be coupled to the case body (410). By being coupled to the case body (410), the case cover (420) can cover the case body (410), the plurality of guide holes (411), and the terminal holder (320) of the plurality of internal terminals (300).

[0150] For example, the case cover (420) can be attached to the case body (410) from the outside. The outer attachment portion (423) of the case cover (420) can be attached to the outer attachment portion (413) formed on the periphery of the case body (410). For example, the outer attachment portion (413) of the case body (410) has a protruding shape that protrudes from the periphery of the case body (410) and can be caught in a hole formed in the outer attachment portion (423) of the case cover (420), thereby allowing the case body (410) and the case cover (420) to be attached to each other.

[0151] For example, the outer connecting portion (423) of the case cover (420) may come into contact with the perimeter surface of the case body (410).

[0152] For example, the case cover (420) can be joined to the inside of the case body (410). The inner joining portion (424) of the case cover (420) can be formed around the perimeter of the cover positioning hole (422) described later, and can be joined to the inner joining portion (414) formed around the perimeter of the body positioning hole (412) described later of the case body (410). For example, the inner joining portion (414) of the case body (410) has a protrusion shape that protrudes from the perimeter of the body positioning hole (412) and can be caught in the hole formed in the inner joining portion (424) of the case cover (420), thereby allowing the case body (410) and the case cover (420) to be joined to each other.

[0153] For example, the inner coupling portion (424) of the case cover (420) is extended to be inserted into the body positioning hole (412) and can come into contact with the periphery of the body positioning hole (412).

[0154] For example, a third inclined surface (417) may be formed around the body positioning hole (412) to guide the insertion of the inner coupling portion (424) of the case cover (420). The third inclined surface (417) may be formed on one side adjacent to the case cover (420) of the case body (410). The third inclined surface (417) may be inclined such that the width of the body positioning hole (412) becomes narrower as it faces the direction in which the inner coupling portion (424) of the case cover (420) is inserted into the body positioning hole (412).

[0155] However, the configuration for combining the case cover (420) and the case body (410) is not limited thereto, and according to various embodiments, the case cover (420) may be combined with the case body (410) by various methods such as screw fastening.

[0156] According to one embodiment, the thickness of the case cover (420) may be thinner than the thickness of the case body (410). Here, the thickness may be the thickness measured in the direction in which the case cover (420) and the case body (410) face each other, and this may be approximately the same as the thickness measured in the direction in which the terminal holder (320) is inserted into the guide hole (411).

[0157] In this way, the terminal case (400) includes a case body (410) and a case cover (420), and a guide hole (411) is formed in the case body (410). The case cover (420) is coupled to the case body (410) to cover the guide hole (411) and the terminal holder (320) inserted therein, thereby allowing the multiple external terminals (200) and multiple internal terminals (300) to be protected more efficiently from high temperatures and foreign substances inside the housing (103). Furthermore, with this configuration, the process of inserting the terminal holder (320) of the multiple internal terminals (300) into the guide hole (411) of the terminal case (400) and coupling the multiple internal terminals (300) to the terminal case (400) can be performed easily and more efficiently.

[0158] As described above, a plurality of external terminals (200) and a plurality of internal terminals (300) can be connected in a one-to-one correspondence. In this case, the terminals corresponding to each other may be predetermined, and if terminals that do not correspond to each other are connected to each other, a connection failure may occur.

[0159] Accordingly, according to one embodiment, a plurality of external terminals (200), a plurality of internal terminals (300), and a terminal case (400) that guides and supports them can be configured such that when the plurality of external terminals (200) and the plurality of internal terminals (300) are to be connected according to a predetermined corresponding relationship, they can be connected to each other, but when the plurality of external terminals (200) and the plurality of internal terminals (300) are to be incorrectly connected in a relationship different from the above corresponding relationship, they cannot be connected to each other. This prevents a failure in the connection of the plurality of external terminals (200) and the plurality of internal terminals (300).

[0160] To implement this function, based on the terminal case (400) being positioned at a predetermined location (hereinafter referred to as the "first location") for a plurality of external terminals (200), the terminal holder (320) of a plurality of internal terminals (300) inserted into a plurality of guide holes (411) and the connection plate (220) of a plurality of external terminals (200) may be coupled to correspond to each other. For example, based on the terminal case (400) being positioned at the first location for a plurality of external terminals (200), the connection plate (220) of each of the plurality of external terminals (200) may be positioned to correspond to be inserted into a corresponding guide hole (411) among the plurality of guide holes (411) (i.e., a guide hole (411) into which the terminal holder (320) of a corresponding internal terminal (300) among the plurality of internal terminals (300) is inserted).

[0161] In contrast, based on the terminal case (400) being positioned at a position rotated from a first position with respect to a plurality of external terminals (200) (hereinafter referred to as "second position," where the angle between the first position and the second position is greater than 0 degrees and less than 360 degrees), the terminal holder (320) of each of the plurality of internal terminals (300) inserted into the plurality of guide holes (411) may be positioned offset from the connection plate (220) of each of the plurality of external terminals (200). For example, based on the terminal case (400) being positioned at a second position with respect to a plurality of external terminals (200), the connection plate (220) of each of the plurality of external terminals (200) may be positioned offset so as not to be inserted into each of the plurality of guide holes (411).

[0162] That is, the plurality of external terminals (200) can be inserted into the plurality of guide holes (411) and coupled with the plurality of internal terminals (300) only when the terminal case (400) is in a predetermined first position for the plurality of external terminals (200), and otherwise, it is impossible for the plurality of external terminals (200) to be inserted into the plurality of guide holes (411) and the plurality of external terminals (200) cannot be coupled with the plurality of internal terminals (300).

[0163] Each of the plurality of guide holes (411) may include a lead area (411a) into which an external terminal lead (210) is inserted, and a connection area (411b) into which a terminal holder (320) and a connection plate (220) are inserted and connected to each other. When the terminal holder (320) and the connection plate (220) are combined within the guide hole (411), the external terminal lead (210) may be placed in the lead area (411a) of the guide hole (411), and the terminal holder (320) and the connection plate (220) may each be placed in the connection area (411b) of the guide hole (411).

[0164] In each of the plurality of guide holes (411), the lead region (411a) and the connection region (411b) can be connected to each other. However, in each of the plurality of guide holes (411), the lead region (411a) and the connection region (411b) may have different widths and shapes. For example, the lead region (411a) may have a width and shape corresponding to at least a part of the external terminal lead (210), and the connection region (411b) may have a width and shape corresponding to the terminal holder (320). Accordingly, the external terminal lead (210) can be inserted into the lead region (411a), but the terminal holder (320) and the connection plate (220) cannot be inserted. Similarly, the terminal holder (320) and the connection plate (220) can be inserted into the connection region (411b), but the external terminal lead (210) cannot be inserted.

[0165] As illustrated in FIG. 11, some of the plurality of guide holes (411) may have a connection area (411b) closer to the central axis (401) of the terminal case (400) than a lead area (411a). Additionally, some of the other portions of the plurality of guide holes (411) may have a lead area (411a) closer to the central axis (401) of the terminal case (400) than a connection area (411b). In this case, as shown in FIG. 12, some of the external terminals (200) may have the connecting plate (220) closer to the center axis (401) of the terminal case (400) than the external terminal lead (210) when the external terminal lead (210) and the connecting plate (220) are inserted into the guide hole (411), and other of the external terminals (200) may have the external terminal lead (210) closer to the center axis (401) of the terminal case (400) than the connecting plate (220) when the external terminal lead (210) and the connecting plate (220) are inserted into the guide hole (411).

[0166] Accordingly, the connection plate (220) and the external terminal lead (210) can be inserted into the guide hole (411) only when the terminal case (400) is in a predetermined first position for the plurality of external terminals (200). That is, the plurality of external terminals (200) and the plurality of internal terminals (300) can be connected to each other only when the terminal case (400) is in a predetermined first position for the plurality of external terminals (200). By doing so, it is possible to prevent the case where the plurality of external terminals (200) and the plurality of internal terminals (300) are incorrectly connected to each other, thereby preventing a connection failure.

[0167] FIGS. 11 and 12 illustrate an example in which, among the plurality of guide holes (411), the connection area (411b) is closer to the central axis (401) of the terminal case (400) than the lead area (411a) in one of the guide holes (411), and among the plurality of guide holes (411), the lead area (411a) is closer to the central axis (401) of the terminal case (400) than the connection area (411b) in two of the guide holes (411), but is not limited thereto. In contrast, in various embodiments, the connection area (411b) is closer to the central axis (401) of the terminal case (400) than the lead area (411a) in two of the plurality of guide holes (411), and the lead area (411a) is closer to the central axis (401) of the terminal case (400) than the connection area (411b) in one of the plurality of guide holes (411).

[0168] In addition, in various embodiments, the terminal case (400) may have various structures such that each of the plurality of external terminals (200) can be inserted into the guide hole (411) only when the plurality of external terminals (200) are in a first position, thereby allowing the plurality of external terminals (200) and the plurality of internal terminals (300) to be connected to each other, and otherwise, the plurality of external terminals (200) and the plurality of internal terminals (300) cannot be connected to each other, such that each of the plurality of external terminals (200) cannot be inserted into the guide hole (411).

[0169] To improve the efficiency of the process of connecting the external terminal (200) and the internal terminal (300), the terminal case (400) may include a positioning hole (402). The positioning hole (402) may be provided so that an assembly tool (T, see FIG. 13 and FIG. 14) is inserted into the positioning hole (402) to guide the terminal case (400) to a first position relative to a plurality of external terminals (200).

[0170] For example, the assembly tool (T) may include a positioning pin (T3) provided to be inserted into a positioning hole (402), and the positioning pin (T3) may have a shape corresponding to the positioning hole (402) so that it can be inserted into the positioning hole (402) only at a specific position (e.g., a specific angle) with respect to the terminal case (400) (see FIG. 13 and FIG. 14).

[0171] As described, the positioning hole (402) may have a cross-section of a polygonal shape, such as a pentagon. Alternatively, the positioning hole (402) may have a cross-section of various shapes in which the distance from the central axis (401) of the terminal case (400) to the perimeter varies depending on the position. Here, the cross-section of the positioning hole (402) may be defined as a surface in which the positioning hole (402) is cut in a direction perpendicular to the direction in which the assembly tool (T) is inserted into the positioning hole (402).

[0172] For example, the positioning hole (402) may be located at the center of the terminal case (400), but the location of the positioning hole (402) is not limited thereto.

[0173] The positioning hole (402) may include a cover positioning hole (422) formed in the case cover (420) and a body positioning hole (412) formed in the case body (410). The cover positioning hole (422) and the body positioning hole (412) may be positioned at corresponding locations. The cover positioning hole (422) and the body positioning hole (412) may have corresponding shapes.

[0174] For example, the cover positioning hole (422) may extend from one side opposite the case body (410) of the case cover (420) to the other side. That is, the cover positioning hole (422) may penetrate the case cover (420). Alternatively, the cover positioning hole (422) may have the shape of a concave groove that extends from one side opposite the case body (410) of the case cover (420) but does not completely penetrate the case cover (420).

[0175] For example, the body positioning hole (412) may extend from one side adjacent to the case cover (420) of the case body (410) to the other side. That is, the body positioning hole (412) may penetrate the case body (410). Alternatively, the body positioning hole (412) may have the shape of a concave groove that extends from one side adjacent to the case cover (420) of the case body (410) but does not completely penetrate the case body (410).

[0176] Alternatively, the positioning hole (402) may be formed only in the case cover (420) and not in the case body (410).

[0177] Hereinafter, with reference to FIGS. 13 and 14, an example of a method for connecting a plurality of external terminals (200) and a plurality of internal terminals (300) to each other using an assembly tool (T) will be described.

[0178] FIG. 13 is a drawing illustrating the process of joining a plurality of internal terminals and a plurality of external terminals of a compressor according to one embodiment of the present disclosure using an assembly tool. FIG. 14 is a drawing illustrating the process of joining a plurality of internal terminals and a plurality of external terminals of a compressor according to one embodiment of the present disclosure using an assembly tool.

[0179] Referring to FIGS. 13 and 14, in the process of manufacturing a compressor (100) according to one embodiment of the present disclosure, the process of combining a plurality of internal terminals (300) and a plurality of external terminals (200) can be performed using an assembly tool (T).

[0180] The assembly tool (T) may include a first case holder (T1) and a second case holder (T2) configured to grasp and move the terminal case (400). The first case holder (T1) and the second case holder (T2) may be configured to grasp the terminal case (400) by supporting the outer surface of the terminal case (400) at different positions. For example, the first case holder (T1) and the second case holder (T2) may be configured to grasp the terminal case (400) by pressing the terminal case (400) from opposite directions. For example, the first case holder (T1) may press the terminal case (400) downward while covering at least a portion of the upper surface (400a) of the terminal case (400), and the second case holder (T2) may press the terminal case (400) upward while covering at least a portion of the lower surface (400b) of the terminal case (400). Thus, the first case holder (T1) and the second case holder (T2) can hold and move the terminal case (400) together.

[0181] When the first case holder (T1) and the second case holder (T2) grasp the terminal case (400), the positioning pin (T3) of the assembly tool (T) can be inserted into the positioning hole (402) of the terminal case (400). Thereby, the terminal case (400) can be guided to a predetermined first position for a plurality of external terminals (200).

[0182] The assembly tool (T) can move toward a plurality of external terminals (200) fixed to the housing (103) while holding the terminal case (400). Subsequently, the assembly tool (T) can press the case cover (420) in a direction toward the case body (410) from the case cover (420), and the plurality of external terminals (200) can be inserted into corresponding guide holes (411). In this way, the plurality of external terminals (200) and the plurality of internal terminals (300) can be combined and connected to each other.

[0183] When the process of connecting a plurality of external terminals (200) and a plurality of internal terminals (300) is completed, the assembly tool (T) can be separated from the terminal case (400).

[0184] According to one embodiment, the process of connecting a plurality of internal terminals (300) and a plurality of external terminals (200) using an assembly tool (T) as described above can be performed by an automated system.

[0185] Hereinafter, various shapes of positioning holes formed in the terminal case (400) are described by way of example with reference to FIGS. 15 to 21.

[0186] FIG. 15 is a drawing illustrating an example of a terminal case of a compressor and a positioning hole included therein according to one embodiment of the present disclosure.

[0187] Referring to FIG. 15, the terminal case (400) of a compressor (100) according to one embodiment of the present disclosure may include a positioning hole (402-1).

[0188] The positioning hole (402-1) may include a center hole (402a-1) and an extension hole (402b-1) extending from the center hole (402a-1). The center hole (402a-1) and the extension hole (402b-1) may be connected to each other.

[0189] For example, the center hole (402a-1) may be formed in the center of the terminal case (400). For example, the center hole (402a-1) may pass through the central axis (401, see FIG. 10, FIG. 11, etc.) of the terminal case (400).

[0190] For example, the center hole (402a-1) may have a roughly circular cross-section. Unlike as shown in FIG. 15, the center hole (402a-1) may have a roughly elliptical cross-section.

[0191] For example, the extension hole (402b-1) may have a roughly rectangular cross-section. Alternatively, the extension hole (402b-1) may have a long bar-shaped cross-section extending from the center hole (402a-1).

[0192] With this structure, the positioning pin (T3) of the assembly tool (T) can be inserted into the positioning hole (402-1) only at a specific position, and the terminal case (400) can be efficiently guided to a first position for a plurality of external terminals (200).

[0193] FIG. 16 is a drawing illustrating an example of a terminal case of a compressor and a positioning hole included therein according to one embodiment of the present disclosure.

[0194] Referring to FIG. 16, the terminal case (400) of a compressor (100) according to one embodiment of the present disclosure may include a positioning hole (402-2).

[0195] The positioning hole (402-2) may include a center hole (402a-2), a first extension hole (402b-2) extending from the center hole (402a-2), and a second extension hole (402c-2) extending from the center hole (402a-2). The center hole (402a-2), the first extension hole (402b-2), and the second extension hole (402c-2) may be connected to each other.

[0196] The first extension hole (402b-2) and the second extension hole (402c-2) may be positioned on opposite sides relative to the center hole (402a-2). The direction in which the first extension hole (402b-2) extends from the center hole (402a-2) and the direction in which the second extension hole (402c-2) extends from the center hole (402a-2) may be opposite to each other.

[0197] For example, the center hole (402a-2) may be formed in the center of the terminal case (400). For example, the center hole (402a-2) may pass through the central axis (401, see FIG. 10, FIG. 11, etc.) of the terminal case (400).

[0198] For example, the center hole (402a-2) may have a roughly circular cross-section. Unlike as shown in FIG. 16, the center hole (402a-2) may have a roughly elliptical cross-section.

[0199] For example, the first extension hole (402b-2) may have a roughly rectangular cross-section. Alternatively, the first extension hole (402b-2) may have a long bar-shaped cross-section extending from the center hole (402a-2).

[0200] For example, the second extension hole (402c-2) may have a roughly rectangular cross-section. Alternatively, the second extension hole (402c-2) may have a long bar-shaped cross-section extending from the center hole (402a-2).

[0201] With this structure, the positioning pin (T3) of the assembly tool (T) can be inserted into the positioning hole (402-2) only at a specific position, and the terminal case (400) can be efficiently guided to a first position for a plurality of external terminals (200).

[0202] FIG. 17 is a drawing illustrating an example of a terminal case of a compressor and a positioning hole included therein according to one embodiment of the present disclosure.

[0203] Referring to FIG. 17, the terminal case (400) of a compressor (100) according to one embodiment of the present disclosure may include a positioning hole (402-3).

[0204] The positioning hole (402-3) may include a center hole (402a-3), a first extension hole (402b-3) extending from the center hole (402a-3), and a second extension hole (402c-3) extending from the center hole (402a-3). The center hole (402a-3), the first extension hole (402b-3), and the second extension hole (402c-3) may be connected to each other.

[0205] The direction in which the first extension hole (402b-3) extends from the center hole (402a-3) and the direction in which the second extension hole (402c-3) extends from the center hole (402a-3) may form a predetermined angle. In FIG. 17, the direction in which the first extension hole (402b-3) extends from the center hole (402a-3) and the direction in which the second extension hole (402c-3) extends from the center hole (402a-3) are perpendicular to each other are illustrated as an example, but the size of the angle is not limited thereto.

[0206] For example, the center hole (402a-3) may be formed in the center of the terminal case (400). For example, the center hole (402a-3) may pass through the central axis (401, see FIG. 10, FIG. 11, etc.) of the terminal case (400).

[0207] For example, the center hole (402a-3) may have a roughly circular cross-section. Unlike as shown in FIG. 17, the center hole (402a-3) may have a roughly elliptical cross-section.

[0208] For example, the first extension hole (402b-3) may have a roughly rectangular cross-section. Alternatively, the first extension hole (402b-3) may have a long bar-shaped cross-section extending from the center hole (402a-3).

[0209] For example, the second extension hole (402c-3) may have a roughly rectangular cross-section. Alternatively, the second extension hole (402c-3) may have a long bar-shaped cross-section extending from the center hole (402a-3).

[0210] With this structure, the positioning pin (T3) of the assembly tool (T) can be inserted into the positioning hole (402-3) only at a specific position, and the terminal case (400) can be efficiently guided to a first position for a plurality of external terminals (200).

The center hole (402a-4), the first extension hole (402b-4), the second extension hole (402c-4), and the third extension hole (402d-4) may be connected to each other.

[0214] The direction in which the first extension hole (402b-4) extends from the center hole (402a-4), the direction in which the second extension hole (402c-4) extends from the center hole (402a-4), and the direction in which the third extension hole (402d-4) extends from the center hole (402a-4) may form a predetermined angle with respect to each other. In FIG. 18, the direction in which the first extension hole (402b-4) extends from the center hole (402a-4) and the direction in which the second extension hole (402c-4) extends from the center hole (402a-4) are perpendicular to each other are illustrated as an example, but the size of the angle is not limited thereto. In FIG. 18, the direction in which the first extension hole (402b-4) extends from the center hole (402a-4) and the direction in which the third extension hole (402d-4) extends from the center hole (402a-4) are perpendicular to each other are illustrated as an example, but the size of the angle is not limited thereto. In FIG. 18, the second extension hole (402c-4) and the third extension hole (402d-4) are located on opposite sides of the center hole (402a-4), and the direction in which the second extension hole (402c-4) extends from the center hole (402a-4) and the direction in which the third extension hole (402d-4) extends from the center hole (402a-4) form an angle of 180 degrees to each other are illustrated as an example, but the size of the angle is not limited thereto.

[0215] For example, the center hole (402a-4) may be formed in the center of the terminal case (400). For example, the center hole (402a-4) may pass through the central axis (401, see FIG. 10, FIG. 11, etc.) of the terminal case (400).

[0216] For example, the center hole (402a-4) may have a roughly circular cross-section. Unlike as shown in FIG. 18, the center hole (402a-4) may have a roughly elliptical cross-section.

[0217] For example, the first extension hole (402b-4) may have a roughly rectangular cross-section. Alternatively, the first extension hole (402b-4) may have a long bar-shaped cross-section extending from the center hole (402a-4).

In FIG. 19, the direction in which the first extension hole (402b-5), the second extension hole (402c-5), the third extension hole (402d-5), and the fourth extension hole (402d-5) each extend from the center hole (402a-4) is shown as an example where the direction in which the adjacent extension hole extends from the center hole (402a-4) is perpendicular to each other, but the size of the angle is not limited thereto.

[0225] For example, the center hole (402a-5) may be formed in the center of the terminal case (400). For example, the center hole (402a-5) may pass through the central axis (401, see FIG. 10, FIG. 11, etc.) of the terminal case (400).

[0226] For example, the center hole (402a-5) may have a roughly circular cross-section. Unlike as shown in FIG. 19, the center hole (402a-5) may have a roughly elliptical cross-section.

[0232] FIG. 20 is a drawing illustrating an example of a terminal case of a compressor and a positioning hole included therein according to one embodiment of the present disclosure.

[0233] Referring to FIG. 20, the terminal case (400) of a compressor (100) according to one embodiment of the present disclosure may include a positioning hole (402-6).

[0234] The positioning hole (402-6) may include a center hole (402a-6) and an extension hole (402b-6) extending from the center hole (402a-6). The center hole (402a-6) and the extension hole (402b-1) may be connected to each other.

[0235] For example, the center hole (402a-6) may be formed in the center of the terminal case (400). For example, the center hole (402a-6) may pass through the central axis (401, see FIG. 10, FIG. 11, etc.) of the terminal case (400).

[0236] For example, the center hole (402a-6) may have a roughly circular cross-section. Unlike as shown in FIG. 20, the center hole (402a-6) may have a roughly elliptical cross-section.

[0237] For example, the extension hole (402b-6) may have a cross-section that is roughly part of a circle (e.g., a circular sector, a circular segment, etc.).

[0238] For example, the positioning hole (402-6) may have a shape in which circles of different diameters have parts of which overlap each other.

[0243] For example, the center hole (402a-7) may be formed in the center of the terminal case (400). For example, the center hole (402a-7) may pass through the central axis (401, see FIG. 10, FIG. 11, etc.) of the terminal case (400).

[0244] For example, the center hole (402a-7) may have a roughly circular cross-section. Unlike as shown in FIG. 21, the center hole (402a-7) may have a roughly elliptical cross-section.

[0245] For example, the extension hole (402b-7) may have a roughly triangular cross-section.

[0248] In describing the configurations of a compressor (100) according to one embodiment of the present disclosure with reference to FIGS. 22 to 24, the same reference numerals may be assigned to configurations corresponding to the configurations of the embodiments described with reference to FIGS. 1 to 21, and detailed descriptions may not be repeated.

[0249] Referring to FIGS. 22 through 24, a compressor (100) according to one embodiment of the present disclosure may include a terminal case (500). The terminal case (500) may be disposed inside a housing (103). The terminal case (500) may support a plurality of internal terminals (300). The terminal case (500) may cover a plurality of internal terminals (300). The terminal case (500) may accommodate a plurality of internal terminals (300).

[0250] Each terminal holder (320) of a plurality of internal terminals (300) can be placed inside a terminal case (500). The terminal case (500) can cover each terminal holder (320) of a plurality of internal terminals (300).

[0251] When the terminal holder (320) and the connection plate (220) are combined, the connection plate (220) can be placed inside the terminal case (500). When the terminal holder (320) and the connection plate (220) are combined, the terminal case (500) can cover the connection plate (220). The connection plate (220) of each of the plurality of external terminals (200) and the terminal holder (320) of each of the plurality of internal terminals (300) can be combined with each other inside the terminal case (500).

[0252] The terminal case (500) may include a guide hole (511). The guide hole (511) may be provided so that a terminal holder (320) included in each of the plurality of internal terminals (300) is inserted. The guide hole (511) may be provided so that a connecting plate (220) included in each of the plurality of external terminals (200) is inserted. For example, the terminal holder (320) may be inserted from one side of the guide hole (511), and the connecting plate (220) may be inserted from the other side of the guide hole (511).

[0253] By inserting the terminal holder (320) into the guide hole (511), the internal terminal (300) can be coupled to the terminal case (500). By inserting the connecting plate (220) into the guide hole (511), the external terminal (200) can be coupled to the terminal case (500).

[0254] Guide holes (511) may be provided in multiple numbers. In each of the multiple guide holes (511), a connection plate (220) of one of the multiple external terminals (200) and a terminal holder (320) of one of the multiple internal terminals (300) may be inserted. The number of guide holes (511) may be equal to the number of external terminals (200) and the number of internal terminals (300), and for example, the terminal case (500) may include three guide holes (511).

[0255] One side in which the terminal holder (320) of each of the multiple internal terminals (300) is inserted into each of the multiple guide holes (511) may be identical to each other. The other side in which the connecting plate (220) of each of the multiple external terminals (200) is inserted into each of the multiple guide holes (511) may be identical to each other.

[0256] Guide holes (511) may be provided so that the connecting plate (220) and the terminal holder (320) can be coupled to each other within the terminal case (500). Multiple guide holes (511) may guide the terminal holder (320) so that the terminal holder (320) of each of the multiple internal terminals (300) is inserted. Multiple guide holes (511) may guide the connecting plate (220) so that the connecting plate (220) of each of the multiple external terminals (200) is inserted and coupled to the terminal holder (320) within the guide holes (511).

[0257] As the connecting plate (220) and the terminal holder (320) are joined together within the guide hole (511) formed inside the terminal case (500) in this manner, the connecting plate (220) and the terminal holder (320) can be efficiently protected from external high temperatures or foreign substances.

[0258] The terminal case (500) may include a first inclined surface formed around the guide hole (511) on the side in the direction in which the terminal holder (320) is inserted into the guide hole (511). The first inclined surface may be formed so that the width of the guide hole (511) becomes narrower as it faces the direction in which the terminal holder (320) is inserted into the guide hole (511).

[0259] The terminal case (500) may include a second inclined surface (516) formed around the guide hole (511) on the side in which the connecting plate (220) is inserted into the guide hole (511). The second inclined surface (516) may be formed so that the width of the guide hole (511) becomes narrower as it faces the direction in which the connecting plate (220) is inserted into the guide hole (511).

[0260] Multiple guide holes (511) can be partitioned from one another. Thus, terminal holders (320) and connecting plates (220) inserted into different guide holes (511) can be spaced apart from each other, and a short circuit caused by contact between terminals inserted into different guide holes (511) can be efficiently prevented.

[0261] According to one embodiment, each of the plurality of guide holes (511) may be spaced apart from the central axis of the terminal case (500). The central axis of the terminal case (500) may be defined as an axis passing through the center of the terminal case (500) in the direction in which the terminal holder (320) and the connecting plate (220) are inserted into the guide holes (511).

[0262] According to one embodiment, the terminal holder (320) can be fixed within the guide hole (511). The guide hole (511) can be formed to prevent the terminal holder (320) from moving within the guide hole (511). Within the guide hole (511), the terminal holder (320) can be prevented from moving by contacting the inner surface of the terminal case (400) in at least two directions. Thus, the terminal holder (320) and the connecting plate (220) can be easily combined simply by inserting the connecting plate (220) into the guide hole (511) into which the terminal holder (320) is inserted.

[0263] By utilizing the structure of such a terminal case (500), it is possible to simultaneously combine a plurality of external terminals (200) and a plurality of internal terminals (300), and the combining process can be performed easily and efficiently. Furthermore, the process of combining a plurality of external terminals (200) and a plurality of internal terminals (300) can be easily automated.

[0264] According to one embodiment, when the connecting plate (220) is inserted into the guide hole (511), at least a portion of the external terminal lead (210) may also be inserted into the guide hole (511). For example, the external terminal lead (210) may be inserted into the guide hole (511) by penetrating one side adjacent to the housing (103) of the terminal case (400).

[0265] According to one embodiment, the internal terminal lead (310) may penetrate the terminal case (500). The terminal case (500) may include an internal terminal lead hole (530) that is penetrated by the internal terminal lead (310). The internal terminal lead hole (530) may be connected to a guide hole (511).

[0266] For example, an internal terminal lead hole (530) may be formed in the case cover (520). The internal terminal lead hole (530) may be formed on the periphery of the case cover (520). Here, the periphery of the case cover (520) may include a periphery of the case cover (520) facing a direction different from the direction in which the terminal holder (320) and the connecting plate (220) are inserted.

[0267] The internal terminal lead hole (530) may extend in one direction from the periphery of the case cover (520) toward the inside of the case cover (520). The direction in which the internal terminal lead hole (530) extends from the periphery of the case cover (520) and the direction in which the guide hole (511) extends may be perpendicular to each other. For example, the direction in which the internal terminal lead hole (530) extends from the periphery of the case cover (520) and the direction in which the guide hole (511) extends may be approximately perpendicular.

[0268] The terminal case (500) may include a number of internal terminal lead holes (530) corresponding to the number of external terminals (200) (e.g., 3). For example, a plurality of internal terminal lead holes (530) may be spaced apart and partitioned from each other.

[0269] In order to prevent a faulty connection between a plurality of external terminals (200) and a plurality of internal terminals (300), the plurality of external terminals (200) can be inserted into a plurality of guide holes (511) and coupled with a plurality of internal terminals (300) only when the terminal case (500) is in a predetermined first position with respect to the plurality of external terminals (200), and when the terminal case (500) is in a second position rotated from the first position, it is impossible for the plurality of external terminals (200) to be inserted into the plurality of guide holes (511), and the plurality of external terminals (200) may not be coupled with a plurality of internal terminals (300).

[0270] Each of the plurality of guide holes (511) may include a lead area (511a) into which an external terminal lead (210) is inserted, and a connection area (511b) into which a terminal holder (320) and a connection plate (220) are inserted and connected to each other. When the terminal holder (320) and the connection plate (220) are combined within the guide hole (511), the external terminal lead (210) may be placed in the lead area (511a) of the guide hole (511), and the terminal holder (320) and the connection plate (220) may each be placed in the connection area (511b) of the guide hole (511).

[0271] In this embodiment, the features and resulting functions of the lead region (511a) and the connection region (511b) of the guide hole (511) are nearly identical or similar to the features and resulting functions of the lead region (411a) and the connection region (411b) of the guide hole (411) in the embodiment described with reference to FIGS. 4 to 14. For example, some of the plurality of guide holes (511) may have the connection region (511b) closer to the central axis (401) of the terminal case (400) than the lead region (511a). Additionally, some of the other portions of the plurality of guide holes (511) may have the lead region (511a) closer to the central axis (401) of the terminal case (400) than the connection region (511b). Accordingly, the connecting plate (220) and the external terminal lead (210) can be inserted into the guide hole (511) only when the terminal case (500) is in a predetermined first position for the plurality of external terminals (200), and the plurality of external terminals (200) and the plurality of internal terminals (300) can be connected to each other.

[0272] To improve the efficiency of the process of connecting the external terminal (200) and the internal terminal (300), the terminal case (500) may include a positioning hole (522). The positioning hole (522) may be provided so that an assembly tool (T, see FIG. 13 and FIG. 14) is inserted into the positioning hole (522) to guide the terminal case (500) to a first position relative to a plurality of external terminals (200).

[0273] For example, the positioning hole (522) may be formed in at least the case cover (520), and in various embodiments, the positioning hole (522) may also be formed in the case body (510).

[0274] According to one embodiment, the terminal case (500) may include a case body (510) and a case cover (520).

[0275] The case body (510) may be provided to support a plurality of internal terminals (300). Guide holes (511) may be formed in the case body (510). That is, a plurality of guide holes (511) may be formed in the case body (510).

[0276] A plurality of guide holes (511) may extend from one side adjacent to the case cover (520) of the case body (510) to the other side. A terminal holder (320) may be inserted on the side adjacent to the case cover (520), and a connecting plate (220) may be inserted on the opposite side.

[0277] The case cover (520) can cover the case body (510). The case cover (520) can cover the case body (510) from one side. The case cover (520) can cover a plurality of guide holes (511). The case cover (520) can cover each terminal holder (320) of a plurality of internal terminals (300).

[0278] The case cover (520) can cover the case body (510), the plurality of guide holes (511), and the terminal holder (320) of each of the plurality of internal terminals (300) on one side where the terminal holder (320) is inserted into the plurality of guide holes (511).

[0279] The case cover (520) can also cover at least a portion of the internal terminal leads (310) of each of the multiple internal terminals (300).

[0280] The case cover (520) can be coupled to the case body (510). By being coupled to the case body (510), the case cover (520) can cover the case body (510), the plurality of guide holes (511), and the terminal holder (320) of the plurality of internal terminals (300).

[0281] For example, the case cover (520) can be attached to the case body (510) from the outside. The outer attachment portion (523) of the case cover (520) can be attached to the outer attachment portion (523) formed on the periphery of the case body (510). For example, the outer attachment portion (523) of the case cover (520) may have a protrusion shape protruding from the periphery of the case cover (520) and may be caught in a hole formed in the outer attachment portion (513) of the case body (510), thereby allowing the case body (510) and the case cover (520) to be attached to each other.

[0282] For example, the outer connecting portion (413) of the case body (510) can come into contact with the perimeter surface of the case cover (520).

[0283] However, the configuration for combining the case cover (520) and the case body (510) is not limited thereto, and according to various embodiments, the case cover (520) may be combined with the case body (510) by various methods such as screw fastening.

[0284] The case cover (520) may include a cover groove (521) provided to allow a portion of each of the plurality of internal terminals (300) to be inserted. A portion of the terminal holder (320) included in each of the plurality of internal terminals (300) may be inserted into the cover groove (521).

[0285] For example, a portion of an internal terminal lead (310) included in each of a plurality of internal terminals (300) can be inserted into the cover groove (521). The cover groove (521) can be connected to an internal terminal lead hole (530).

[0286] For example, a portion of a terminal holder (320) included in each of the plurality of internal terminals (300) can be inserted into the cover groove (521). A portion of the terminal holder (320) can be inserted into the cover groove (521), and another portion of the terminal holder (320) can be inserted into the guide hole (511). The cover groove (521) can be connected to the guide hole (511).

[0287] The cover groove (521) may have a shape that is concavely recessed from one side facing the case body (510) of the case cover (520).

[0288] The case cover (520) may include an inclined surface (521a) provided around the perimeter of the cover groove (521). The inclined surface (521a) may be formed around the perimeter of the cover groove (521) on the side adjacent to the case body (510) of the case cover (520). The inclined surface (521a) may be formed around the perimeter of the cover groove (521) on the side where a part of the terminal holder (320) is inserted into the cover groove (521). The inclined surface (521a) may be formed so that the width of the cover groove (521) narrows as it faces the direction in which a part of the terminal holder (320) is inserted into the cover groove (521). The inclined surface (521a) may be provided to guide the insertion of a part of the terminal holder (320) into the cover groove (521).

[0289] According to one embodiment, the thickness of the case cover (520) and the thickness of the case body (510) may be nearly the same. Here, the thickness may be the thickness measured in the direction in which the case cover (520) and the case body (510) face each other, and this may be approximately the same as the thickness measured in the direction in which the terminal holder (320) is inserted into the guide hole (511). In this way, by making the thickness of the case cover (520) thick enough to be nearly the same as the thickness of the case body (510), the case cover (520) may be prevented from being separated from the case body (510) by the repulsive force from the external terminal (200) during the step of combining the external terminal (200) and the internal terminal (300).

[0290] In this embodiment, a cover groove (521) into which a part of the terminal holder (320) is inserted and an internal terminal lead hole (530) through which an internal terminal lead (310) passes are formed in the case cover (520), so that the case cover (520) may have a thicker thickness than the case cover (420) according to the embodiment of FIGS. 4 to 14.
