[0006] Patent Document 1: Japanese Patent Application Publication No. 08-049679 Summary of the invention

[0007] Technical problem to be solved by the invention

[0008] The compressor of the above structure is usually arranged in a longitudinal direction in a manner that the central axis of the housing is vertically erected, that is, the compression mechanism and the motor are vertically overlapped inside the housing. With respect to the compressor in such a state, the lead wire connected to the terminal portion is led out from the inside of the terminal cover to the outside in the horizontal direction through the opening provided in the side wall of the terminal cover.

[0009] Here, if there is a margin in the opening of the terminal cover that allows the lead to move, the lead may bend due to its own weight or deform due to external force, causing the lead to move in the opening, and torque to act on the terminal of the lead connected to the terminal portion. As a result, there is a concern that the tightness between the terminal portion on the upper part of the housing and the terminal of the lead will be reduced, resulting in poor contact between the components of the two, resulting in a loss of stability in the power supply to the motor.

[0010] By forming the sealing member into a flat sheet shape, a relatively wide gap that allows the lead wire to move up and down usually remains in the opening of the terminal cover.

[0011] Therefore, an object of the present invention is to suppress the movement of the lead wire and the torque applied to the terminal caused thereby, maintain the close contact between the terminal portion of the upper portion of the housing and the terminal of the lead wire, and realize a more stable power supply to the motor.

[0012] Solutions for solving the above technical problems

[0013] In order to solve the above technical problems, a compressor according to an embodiment of the present invention comprises: a housing; a compression mechanism portion, which is accommodated in the housing; a motor, which is accommodated in the housing and is configured to drive the compression mechanism portion; a terminal portion, which is provided at the upper portion of the housing and is configured to be connected to a lead wire for supplying power to the motor; a terminal cover, which surrounds the terminal portion; and a sealing member, which is arranged between the terminal cover and the upper portion of the housing. The terminal cover has an opening portion that opens in a direction perpendicular to the central axis of the housing, and the lead wire can be led out of the terminal cover from the inside of the terminal cover through the opening portion. The sealing member has: a sheet-shaped sealing member body, which has a sealing portion sandwiched by the edge of the terminal cover and the upper portion of the housing that are opposed to each other; and a convex portion, which is formed to protrude from the sealing member body and occupies at least a part of the space of the opening portion in a projection relative to a plane parallel to the central axis of the housing.

[0014] Preferably, in the compressor of the embodiment of the present invention, the upper part of the shell is convex relative to the central axis of the shell, the sealing part body of the sealing part is elastic, and the convex part is arranged between the terminal cover and the upper part of the shell in a state of contact with the lead wire, and a gap is formed between the sealing part body and the upper part of the shell, and the gap allows the sealing part body to deform downward with the sealing part as the center.

[0015] Preferably, in the compressor according to the embodiment of the present invention, the sealing member body of the sealing member is formed integrally with the convex portion.

[0016] Preferably, in the compressor according to the embodiment of the present invention, the sealing member is made of a rubber material, and the sealing member body and the convex portion are formed by integral molding.

[0017] Furthermore, in order to solve the technical problem, a sealing component of an embodiment of the present invention is installed on a housing, the housing having a housing body, an upper part and a lower part, a compression mechanism and a motor as a driving source thereof are accommodated in the housing body, and a terminal part configured to be connected to a lead wire for supplying power to the motor is provided in the upper part, and the sealing component is a sealing component arranged between a terminal cover surrounding the terminal part and the upper part of the housing. The terminal cover has an opening part opening in a direction perpendicular to the central axis of the housing, and the lead wire can be led out of the terminal cover from the inside of the terminal cover through the opening part. The sealing component has: a sheet-shaped sealing component body, which has a sealing part clamped by the edge of the terminal cover and the upper part of the housing facing each other; and a convex part, which is formed protruding from the sealing component body, and can occupy at least a part of the space of the opening part in the projection relative to a plane parallel to the central axis of the housing when the sealing component is installed in the housing.

[0018] Effects of the Invention

[0019] According to the present invention, the movement of the lead wire and the torque applied to the terminal caused thereby can be suppressed, and the close contact between the terminal portion of the upper portion of the housing and the terminal of the lead wire can be maintained, thereby contributing to a more stable power supply to the motor.

[0020] In the embodiment of the present invention, by using the convex portion to reduce the gap remaining in the opening of the terminal cover, it is possible to suppress the deflection of the lead due to its own weight or the deformation caused by the action of an external force, which causes the lead to move in the opening of the terminal cover, and it is also possible to suppress the torque acting on the terminal of the lead. Thus, a good contact state between the terminal portion and the terminal of the lead is maintained.

[0021] In other embodiments, the sealing component body is made elastic and is arranged in a state where the convex portion contacts the lead. Furthermore, by setting the upper portion of the shell to be convex upward, a gap is formed between the sealing component body and the upper portion of the shell to allow the sealing component body to deform downward, thereby overcoming the deflection or deformation of the lead and supporting the lead, and more effectively suppressing the torque acting on the terminal of the lead.

[0022] In still another embodiment, by integrally forming the sealing member main body and the convex portion, it is possible to facilitate simplification of the configuration of the sealing member and to achieve labor saving in the work of installing the sealing member.

[0023] Furthermore, since the sealing member main body and the convex portion can be managed as a single component, the storage and management of the sealing member can be facilitated.

[0024] In still another embodiment, by forming the seal member body and the convex portion by integrally molding the rubber material, it is possible to promote improvement in the productivity of the seal member and to reduce the manufacturing cost of the seal member.

[0025] Furthermore, by using a rubber material with appropriate softness, the closeness between the sealing component body and the upper part of the housing, and the closeness between the sealing component body and the terminal cover can be improved, and at the same time, damage to the lead wire caused by contact with the terminal cover can be suppressed. Thus, by reducing the opening of the terminal cover as much as possible, foreign matter such as water or dust can be suppressed from entering the interior of the terminal cover.

[0034] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0035] Figure 1 and Figure 2 A compressor (hereinafter simply referred to as a "compressor") C according to an embodiment of the present invention is shown in a state when installed in a refrigeration cycle apparatus. Figure 1 The vertical view of the compressor C is shown from the side. Figure 2 It is a plan view showing the compressor C as seen from above.

[0036] Figures 3 to 5 The structure inside the terminal cover 2 in the compressor C is shown. Figure 3 yes Figure 2 The cross-sectional view of line xx, Figure 4 yes Figure 3 The cross-sectional view of the yy line, Figure 5 yes Figure 3 Cross-sectional view of line zz.

[0037] In the present embodiment, the compressor C is a so-called sealed rotary compressor. The compressor C is applied to a refrigeration cycle device, which sucks in the low-temperature and low-pressure refrigerant gas from the evaporator and compresses it, so that the refrigerant gas becomes a high-temperature and high-pressure superheated vapor and is discharged. The refrigerant discharged by the compressor C is supplied to the condenser. In the refrigeration cycle device, the evaporator constitutes a heat source, and the condenser constitutes a heat source. The evaporator, the compressor C and the condenser are connected in sequence with respect to the flow of the refrigerant through a refrigerant pipe. An expansion valve is provided between the condenser and the evaporator. As refrigeration cycle devices to which the compressor C can be applied, refrigerators, water heaters and air conditioners can be exemplified.

[0038] The compressor C includes a compressor body 1 and an accumulator 5. In the present embodiment, the compressor body 1 and the accumulator 5 are integrated and the accumulator 5 is configured as an element or component of the compressor C. However, the accumulator 5 may be configured as a refrigeration cycle element independent of the compressor C.

[0039] The compressor body 1 is connected to the accumulator 5 via the refrigerant suction pipe 61 , and sucks the refrigerant gas from the evaporator through the accumulator 5 .

[0040] The accumulator 5 is also called a suction muffler or a gas-liquid separator, and when a refrigerant in a liquid or liquid droplet state other than vapor is mixed in the refrigerant gas coming out of the evaporator, the accumulator 5 separates the vapor from the liquid or liquid droplet, discharges only the vapor, and sucks it into the compressor body 1. The accumulator 5 includes an inlet pipe 51 and an outlet pipe 52, and receives the supply of the refrigerant gas through the inlet pipe 51. In the present embodiment, the outlet pipe 52 also serves as the refrigerant suction pipe 61 of the compressor body 1.

[0041] In this embodiment, the compressor body 1 includes a housing 11, a compression mechanism 12, and a motor 13. The compression mechanism 12 and the motor 13 are both airtightly accommodated in the housing 11. For the convenience of illustration, Figure 1 The outer shapes of the compression mechanism 12 and the motor 13 are schematically shown by two-dot chain lines.

[0042] The housing 11 includes a housing body 11a, a housing upper portion 11b, and a housing bottom 11c. The housing body 11a is a hollow cylindrical shape that penetrates from top to bottom, and has a space inside to accommodate the compression mechanism 12 and the motor 13. The housing upper portion 11b is joined to the upper end of the housing body 11a to airtightly seal the opening at the upper end of the housing body 11a. The housing bottom 11c is joined to the lower end of the housing body 11a to airtightly seal the opening at the lower end of the housing body 11a.

[0043] In this embodiment, the housing upper portion 11b and the housing bottom 11c are both formed of disk-shaped end plates, which are respectively joined to the housing body 11a by appropriate methods such as welding. In addition, the compressor C is arranged in a state in which the central axis Ax1 of the housing 11 is vertically erected, that is, the compression mechanism 12 and the motor 13 described below are arranged vertically in the housing 11 in a state of being overlapped up and down.

[0044] The compression mechanism 12 is accommodated in the lower half of the housing body 11 a in the housing 11 .

[0045] The motor 13 is accommodated in the upper half of the housing body 11 a inside the housing 11 .

[0046] The motor 13 constitutes the driving source of the compression mechanism 12, and includes a stator and a rotor. The stator is cylindrical and fixed to the housing body 11a, and the rotor is arranged on the inner diameter side of the stator and is supported to rotate freely relative to the housing body 11a. The rotor of the motor 13 is connected to the compression mechanism 12 via a crankshaft, and the electromagnetic attraction force is applied to the rotor by energizing the electromagnetic coil formed on the stator, thereby rotating the rotor. In addition, the motor 13 transmits the driving force generated in the rotation direction of the rotor to the compression mechanism 12 via the crankshaft, thereby driving the compression mechanism 12. In the present embodiment, the motor 13 is a three-phase induction motor.

[0047] Here, the compression mechanism 12 includes a cylinder and a rolling piston. The cylinder is cylindrical and fixed coaxially with the rotor and crankshaft of the motor 13 relative to the shell body 11a. The rotary piston is arranged on the inner diameter side of the cylinder. It is supported eccentrically and rotatably relative to the cylinder through the eccentric portion provided on the crankshaft. The compression mechanism 12 sucks in the refrigerant and compresses it according to the rotation of the rotary piston inside the cylinder. In this embodiment, in the cylinder, a groove is continuously formed from the space on the inner diameter side thereof to the radial outside, and a partition plate (also referred to as a "blade") is accommodated in the groove. The partition plate is in sliding contact with the outer peripheral surface of the rotary piston, so that the space between the cylinder and the rotary piston is divided into a suction chamber and a compression chamber. The compressed refrigerant is discharged to the condenser via the space inside the shell 11 and then the refrigerant discharge pipe 62.

[0048] Furthermore, lubricating oil is sealed in the lower half of the housing body 11 a and the housing bottom 11 c , and the compression mechanism 12 is immersed in the lubricating oil.

[0049] In addition to the above, the compressor body 1 includes a terminal portion 14 , and the compressor C includes a terminal cover 2 and a sealing member 3 as components attached to the compressor body 1 .

[0050] like Figure 3 As shown, the terminal portion 14 is an intermediary element that connects the lead wire (also called "power wire", hereinafter referred to as "first lead wire") L extending from the power source (e.g., commercial AC power source) of the motor 13 or a power converter such as an inverter outside the housing 11 to the lead wire (also called "lead wire", hereinafter referred to as "second lead wire") not shown inside the housing 11 extending from the coil winding of the stator, and is provided on the housing upper portion 11b. In this embodiment, three terminal portions 14 are provided according to the number of coil phases of the motor 13.

[0051] In this embodiment, the terminal portion 14 is composed of a terminal pin 141 and a tab terminal 142. The installation base 15 is inserted into an insertion port formed in the housing upper portion 11b, and the terminal portion 14 is mounted on the housing upper portion 11b through the installation base 15. The installation base 15 ensures the insulation distance between the three terminal portions 14.

[0052] Specifically, the terminal pins 141 are fixed to the installation table 15 in a state of penetrating the front and back of the installation table 15. The tab terminals 142 are in the form of flat plates, and are fixed to the terminal pins 141 by welding or the like.

[0053] Reference Figure 4, when the tab terminals 142 are fixed to the terminal pins 141, their surfaces face different directions from each other, and among the tab terminals 142 constituting each of the three terminal portions 14, a plane including the surface of one tab terminal 142 is in a positional relationship that divides the angle formed by the planes including the surfaces of the other two tab terminals 142 into two. In the present embodiment, the terminal pins 141 constituting each of the three terminal portions 14 are in a mutual relationship located at the vertices of an equilateral triangle, and among the three tab terminals 142, two planes including the surfaces of the tab terminals 142 intersect each other to form an acute angle, and the plane including the surface of the other tab terminal 142 is in a positional relationship that divides the acute angle into two equal parts.

[0054] Furthermore, by installing a quick-connect terminal F at the front end of the first lead L and installing the quick-connect terminal F to the tab terminal 142, the first lead L is connected to the second lead inside the housing 11 via the terminal portion 14, and power can be supplied from the power supply to the motor 13. In the present embodiment, when the first lead L is connected to the terminal portion 14, the length direction of the terminal pin 141 and the length direction of the first lead L are perpendicular to each other, and the first lead L is led out from the terminal portion 14 in a direction perpendicular to the central axis Ax1 of the housing 11, that is, in the lateral direction.

[0055] The terminal cover 2 is mounted on the upper part 11b of the housing, and surrounds the terminal part 14 and the mounting platform 15 to protect them from contact with foreign matter such as water or dust. The terminal cover 2 includes a cover body 21 and an extension part 22. In the present embodiment, the cover body 21 and the extension part 22 are integrally formed of a suitable material such as resin, and the terminal cover 2 is mounted on the upper part 11b of the housing by being constrained by a fastening belt 16 mounted on the cover body 21. The fastening belt 16 is fixed to the upper part 11b of the housing via a ring-shaped guide member 17 that is arranged so as to surround the cover body 21 over half of the circumference of the cover body 21.

[0056] The cover body 21 is cylindrical with a cover, and has a space inside for accommodating the terminal portion 14. The cover body 21 also has an opening 21a on its side wall. When the terminal cover 2 is mounted on the housing upper portion 11b, the opening 21a opens in a direction perpendicular to the central axis Ax1 of the housing 11.

[0057] The extension portion 22 is continuously provided with the opening portion 21a, and shields the space inside the terminal cover 2 from the outside when viewed from the outside of the terminal cover 2 in a direction perpendicular to the central axis Ax1 of the housing 11. In the present embodiment, the extension portion 22 is in a roof-like shape extending from the opening portion 21a, has a gradient descending toward the outside of the cover body 21, and extends from the opening portion 21a in a manner that blocks the line of sight toward the inside of the terminal cover 2 in a direction perpendicular to the central axis Ax1 of the housing 11. The first lead L connected to the terminal portion 14 is led out of the terminal cover 2 from the inside of the terminal cover 2 through the opening portion 21a and the extension portion 22.

[0058] The sealing member 3 is disposed between the terminal cover 2 and the housing upper portion 11 b.

[0059] Figure 6 The structure of the sealing member 3 included in the compressor C is shown. Figure 6 (a) is a top view of the sealing component 3, Figure 6 (b) is a front view of the sealing component 3, Figure 6 (c) is the sealing component 3 Figure 6 A cross-sectional view of the line a1-a1 shown in (a).

[0060] The sealing component 3 includes a sealing component body 31 and a convex portion 32. In the present embodiment, the sealing component body 31 and the convex portion 32 are formed as one body, and the sealing component 3 is formed as a single component or part. Specifically, the entire sealing component 3 including the convex portion 32 is formed of a resin material, and the sealing component body 31 and the convex portion 32 are formed as one body by mold forming or the like. As materials that can be applied to the sealing component 3, various natural or synthetic resin materials, such as rubber materials, can be exemplified. Furthermore, the sealing component 3 is not limited to the sealing component body 31, and the convex portion 32 also preferably has moderate elasticity.

[0061] The sealing member main body 31 is in a flat sheet shape as a whole, and includes a sealing portion 31 a and a tongue-shaped portion 31 b .

[0062] When the terminal cover 2 is mounted on the upper part 11b of the housing, the sealing portion 31a is clamped by the edge of the terminal cover 2 and the upper part 11b of the housing, which are opposite to each other, and a liquid-tight seal is given to the joint surfaces of these parts. In the present embodiment, the sealing portion 31a is located between the edge of the cover body 21 and the upper part 11b of the housing opposite thereto. The sealing component body 31 has an insertion port h formed so as to allow the setting table 15 of the terminal portion 14 to be embedded, and the sealing portion 31a surrounds the insertion port h over the entire circumference of the insertion port h.

[0063] The tongue-shaped portion 31b is formed as an extension extending radially outward from the sealing portion 31a relative to the center line Ax2 of the insertion port h. Figure 3As shown, when the terminal cover 2 is mounted on the upper portion 11b of the housing, the tongue portion 31b contacts the edge of the extension portion 22 in the terminal cover 2. In this embodiment, the tongue portion 31b blocks the extension portion 22 from below to prevent foreign matter from invading the interior of the terminal cover 2 through the opening 21a, and holds the convex portion 32 described below, which helps to determine its position.

[0064] The convex portion 32 is formed to protrude from the tongue-shaped portion 31b in the sealing member body 31 in a direction parallel to the central axis Ax2 of the insertion port h, and occupies a portion of the space S of the opening 21a in the projection relative to the plane parallel to the central axis Ax1 of the housing 11. In other words, at least a portion of the projection of the convex portion 32 relative to the plane parallel to the central axis Ax1 of the housing 11 overlaps with the projection of the space S of the opening 21a.

[0065] Here, “occupying a part of the space of the opening 21a” means excluding the state where the convex portion 32 occupies the entire space S of the opening 21a. In other words, it means that when the first lead L is led out from the inside of the terminal cover 2 to the outside of the terminal cover 2, at least a gap for the first lead L to pass through is left. In this embodiment, Figure 3 As shown, the convex portion 32 is entirely located in the space of the extension portion 22 that is continuous from the opening portion 21a, and the projection of the convex portion 32 relative to a plane parallel to the central axis Ax1 of the housing 11 entirely coincides with the projection of the space S of the opening portion 21a. Furthermore, the projection of the convex portion 32 relative to a plane perpendicular to the central axis Ax1 of the housing 11 entirely coincides with the projection of the space of the extension portion 22.

[0066] In this embodiment, "projection with respect to a plane parallel to the central axis Ax1 of the housing 11" means projection with respect to a plane parallel to the central axis Ax1 of the housing 11 and having the largest projection area of ​​the convex portion 32, which is roughly equivalent to Figure 4 In the plan view shown, it is a plane perpendicular to the first lead L led out from the terminal portion 14 near the center of the opening 21 a.

[0067] Furthermore, when the terminal cover 2 is mounted on the housing upper portion 11b, the convex portion 32 is Figure 3 As shown, the upper end portion thereof contacts the first lead L. That is, the first lead L is sandwiched from above and below by the extension portion 22 and the convex portion 32 , supported upward from below by the convex portion 32 , and is in a state of being elastically pressed against the extension portion 22 .

[0068] Here, a small gap remains between the tongue-shaped portion 31b of the sealing component body 31 and the upper portion 11b of the housing, and the sealing component body 31 can be bent or deformed downward with the sealing portion 31a as the center due to the force applied to the tongue-shaped portion 31b or the convex portion 32. For example, when the first lead L is pressed downward, the sealing component body 31 can deform along with the first lead L. Figure 3 The outer shape of the deformed sealing member main body 31 is schematically shown by a dotted line.

[0069] In this embodiment, the portion around the terminal portion 14 in the upper portion 11b of the housing is formed as a flat surface, and the portion around it is formed as a convex surface. In addition, the sealing component body 31 is configured such that the sealing portion 31a is assembled at the boundary between the flat surface and the convex surface of the upper portion 11b of the housing or straddles the boundary. With such a configuration, in a normal state where no load is applied to the first lead L or even if a load is applied, the tongue-shaped portion 31b is in a state where its end is floated from the upper portion 11b of the housing, and when the first lead L is pressed downward, the tongue-shaped portion 31b moves downward along with the convex portion 32 following the first lead L.

[0070] Thus, the sealing portion 31a of the sealing component main body 31 is reliably pressed against the upper portion 11b of the shell, especially the portion around the flat terminal portion 14, through the edge of the end cover 2, thereby ensuring good sealing. At the same time, a moderate elastic force is applied by the tongue-shaped portion 31b extending outward from the sealing portion 31a, thereby ensuring proper tracking of the first lead L.

[0071] Furthermore, even if the sealing member body 31 is thin and a required elastic force cannot be obtained by the sealing member body 31 , appropriate followability to the first lead L can be achieved by adjusting the elastic force of the convex portion 32 .

[0072] The compressor C and the sealing member 3 of the present embodiment have the above-described configurations. Hereinafter, the effects obtained by the present embodiment will be described.

[0073] First, the sealing member 3 is provided with a sheet-shaped sealing member body 31 and a convex portion 32 formed to protrude from the sealing member body 31, and the convex portion 32 occupies at least a part of the space S in the opening portion 21a of the terminal cover 2 in the projection relative to the plane parallel to the central axis Ax1 of the housing 11. As a result, the gap remaining in the opening portion 21a of the terminal cover 2 can be reduced, and the movement of the first lead L in the opening portion 21a of the terminal cover 2 can be suppressed. For example, the first lead L can be suppressed from being bent due to its own weight or deformed due to the action of an external force, which causes the first lead L to sag from the connection portion with the terminal portion 14, which is the position of the quick-connect terminal F in this embodiment, and the moment acting on the quick-connect terminal F can be suppressed.

[0074] This maintains a good contact state between the terminal portion 14 and the first lead L, particularly between the tab terminal 142 and the quick-connect terminal F in the present embodiment, thereby contributing to a more stable power supply to the motor 13 .

[0075] Specifically, due to the movement of the first lead L, a downward torque acts on the quick-connect terminal F, which may cause looseness in the joint between the quick-connect terminal F and the contact terminal 142, resulting in a reduction in the contact area between the two and insufficient contact. However, by using the convex portion 32 to support the first lead L and suppress its movement, the torque acting on the quick-connect terminal F can be suppressed, thereby avoiding the insufficient contact area caused by the looseness of the joint.

[0076] Furthermore, as the gap remaining in the opening portion 21a of the terminal cover 2 is reduced, in addition to avoiding bending or deformation of the first lead L, the following situation can also be avoided: in the first lead L, due to changes in vibration transmitted from the motor 13 or other peripheral devices housed in the housing 11, excessive load is applied to the quick-connect terminal F.

[0079] exist Figure 7 and Figure 8 In the embodiment, the same elements as those of the compressor C are given the same Figure 3 and Figure 6 The elements shown are denoted by the same reference numerals, and repeated description is omitted.

[0080] In the comparative example, the sealing member 3' is not provided with the convex portion 32, and the sealing member 3' is formed only by an element corresponding to the sealing member body 31, and is flat as a whole. Therefore, when the terminal cover 2 is mounted on the housing upper portion 11b, a margin for allowing the movement of the first lead L remains in the opening portion 21a of the terminal cover 2, and the first lead L is bent due to its own weight or deformed due to external force. If the first lead L moves, the moment corresponding to the movement acts on the quick-connect terminal F connected to the tab terminal 142 of the terminal portion 14. As a result, looseness occurs in the joint between the tab terminal 142 and the quick-connect terminal F, and the contact area between the two is reduced, which may generate heat due to poor contact or impair the stability of the power supply to the motor 13.

[0081] According to the present embodiment, such a situation can be avoided, which contributes to more stable power supply to the motor 13 .

[0082] Secondly, the sealing component body 31 is made elastic, and the sealing component 3 is arranged in a state where the convex portion 32 is in contact with the first lead L. Furthermore, the upper portion 11b of the shell is set to be convex upward, and a gap is formed between the sealing component body 31 and the upper portion 11b of the shell to allow the sealing component body 31 to deform downward, thereby overcoming the deflection or deformation of the first lead L and elastically supporting the first lead L, and more effectively suppressing the torque acting on the quick-connect terminal F.

[0083] Thirdly, by integrally forming the sealing member main body 31 and the convex portion 32 , it is possible to simplify the structure of the sealing member 3 and save labor in the work of installing the sealing member 3 .

[0084] Furthermore, since the sealing member main body 31 and the convex portion 32 can be managed as a single component, the storage and management of the sealing member 3 are also facilitated.

[0085] Fourthly, by forming the seal member main body 31 and the convex portion 32 by integrally molding the rubber material, it is possible to promote improvement in productivity of the seal member 3 and reduce the manufacturing cost of the seal member 3 .

[0086] Furthermore, by using a rubber material having appropriate softness, the closeness between the sealing member body 31 and the housing upper portion 11b and the closeness between the sealing member body 31 and the terminal cover 2 can be improved, and at the same time, damage to the first lead L caused by contact with the sealing member 3, especially the convex portion 32, can be suppressed. Thus, by minimizing the gap remaining in the opening portion 21a of the terminal cover 2 as much as possible, it is possible to suppress foreign matter such as water and dust from entering the interior of the terminal cover 2.

[0087] Furthermore, by making the sealing member 3, especially the sealing member body 31, flexible, the first lead wire L is elastically supported by the convex portion 32, thereby suppressing the movement caused by the bending or deformation thereof, and when the first lead wire L is deformed by the action of an external force, the first lead wire is deformed in a manner following the external force, thereby avoiding the situation where an excessive load is applied to the first lead wire L. As a result, for example, in the installation of the compressor C, the operation of operating or threading the first lead wire L becomes easy.

[0088] In the above description, the sealing component body 31 and the convex portion 32 are integrally formed with the same material, and the sealing component 3 is formed as a single component, but the sealing component 3 is not limited to such a structure. The sealing component body 31 and the convex portion 32 can also be formed separately from the same or different materials, and can be formed separately using the same material, or can be formed integrally using different materials. For example, the sealing component body 31 is formed of a flexible resin material such as a rubber material, while the convex portion 32 is formed integrally or separately with the sealing component body 31 from a material harder than the sealing component body 31, such as a hard plastic material.

[0089] Furthermore, in the above description, the convex portion 32 is configured as being entirely disposed in the extension portion 22 in the terminal cover 2, but the arrangement of the convex portion 32 is not limited thereto, and a portion of the convex portion 32 may be disposed outside the extension portion 22. Specifically, a portion of the convex portion 32 is disposed in the extension portion 22, and the remaining portion is disposed in the cover body 21 or outside the terminal cover 2. Furthermore, the convex portion 32 may also be disposed entirely outside the extension portion 22.

[0090] Several embodiments of the present invention have been described, but these embodiments are presented as examples and are not intended to limit the scope of the invention. These new embodiments can be implemented in various other ways, and various omissions, substitutions, and changes can be made without departing from the scope of the subject matter of the invention. These embodiments and their variations are included in the scope or subject matter of the invention, and are included in the invention described in the claims and the scope of their equivalents.
