Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, and in particular to a terminal cover, a compressor and a refrigeration equipment. Background Art

[0002] Currently, in related technologies, compressors are equipped with terminal covers to protect the compressor terminals, isolating the terminals from the outside air and preventing short circuits and ignitions in the compressor, which could cause explosions in special equipment rooms or when the compressor itself uses flammable refrigerants. However, to ensure a tight seal, the terminal cover must be fixed by welding the entire contact area between the fixing portion and the first shell. This welding generates significant heat, which can cause deformation of the fixing portion and the first shell, resulting in poor sealing of the contact area between the fixing portion and the first shell. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0004] To this end, a first aspect of the present invention provides a terminal cover.

[0005] A second aspect of the present invention provides a compressor.

[0006] A third aspect of the present invention provides a refrigeration device.

[0007] In view of this, the first aspect of the present invention provides a terminal cover for a compressor, the terminal cover comprising a first housing, the terminal cover comprising: a fixing member, a first sealing gasket, a second housing, and a terminal. The fixing member is arranged in the first housing, and the fixing member is provided with a first mounting hole; the first sealing gasket comprises a first body and a first sealing portion, the first body being arranged on a side of the fixing member away from the first housing, arranged around the first mounting hole, the first sealing portion being connected to the first body, located in the first mounting hole, and extending toward the first housing; the second housing being arranged on a side of the first body away from the fixing member, the second housing having a mounting cavity, the mounting cavity being connected to the first mounting hole; the terminal is arranged in the first housing, and is located in the first mounting hole and the mounting cavity.

[0008] This technical solution proposes a terminal cover for a compressor. The terminal cover includes a fixing member, a first sealing gasket, a second housing, and a terminal. The fixing member is mounted on the first housing of the compressor and has a first mounting hole. The first mounting hole facilitates the installation of components within the terminal cover. The first sealing gasket of the terminal cover includes a first body and a first sealing portion. The first sealing gasket is used to seal the terminal cover. The first body is arranged around the first mounting hole and located on the side of the fixing member away from the first housing, ensuring a seal between the fixing member and the second housing. The first sealing portion is connected to the first body and located within the first mounting hole. The first sealing portion extends toward the first housing, ensuring a seal between the fixing member and the first housing. The second housing of the terminal cover is mounted on the side of the first body away from the fixing member. The second housing has a mounting cavity that communicates with the first mounting hole to facilitate the installation of components within the terminal cover. The terminal cover's terminal is mounted on the first housing and located within the first mounting hole and the mounting cavity. The first mounting hole and the mounting cavity facilitate connection of the terminal within the terminal cover. The present application extends the first sealing portion toward the first shell, so that the first sealing portion is used to complete the sealing between the fixing member and the first shell, thereby achieving the sealing between the terminal cover and the first shell, thereby isolating the terminal in the terminal cover from the outside air, and improving the explosion-proof performance of the terminal.

[0009] The terminal cover defined in the present invention extends toward the first shell through the first sealing portion, thereby realizing sealing between the terminal cover and the first shell, and thus no longer requiring sealing to be achieved by integrally welding the contact area between the fixing member and the first shell. This reduces the heat generated when the terminal cover and the first shell are welded, thereby reducing the deformation of the first shell and the fixing member caused by heat, and improving the reliability of the sealing between the terminal cover and the first shell, so that the wiring terminals in the terminal cover are better isolated from the outside air.

[0010] Furthermore, by locating the wiring terminals within the first housing and within the first mounting hole and mounting cavity, the present invention isolates the wiring terminals from the external environment, protecting them from damage by external forces. Furthermore, this isolation reduces the risk of water and dust intrusion, improving their reliability. This prevents short circuits between the wiring terminals and other potential adverse effects on electrical connection performance, thereby improving the operating efficiency and service life of the device.

[0011] At the same time, the utility model avoids the occurrence of contact accidents by isolating the wiring terminals from the external environment, thereby ensuring the safety of operators and users.

[0012] In addition, the terminal cover in the above technical solution provided by the present invention may also have the following additional technical features:

[0013] In some technical solutions of the present invention, optionally, a side of the first sealing portion away from the first body is in contact with the first shell.

[0014] In this technical solution, the first sealing portion extends toward the first housing, so that the first sealing gasket contacts the first housing. The first sealing portion contacts the first housing, thereby isolating the interior space of the terminal cover from the exterior space, thereby improving the explosion-proof performance of the terminal block.

[0015] Optionally, the first sealing portion may also be in contact with the insulating plate and other components of the terminal. By contacting the first sealing portion with the insulating plate and other components of the terminal, the internal space of the terminal cover is isolated from the external space, thereby improving the explosion-proof performance of the terminal.

[0016] In some technical solutions of the present invention, optionally, the first sealing gasket further includes a second sealing portion, which is connected to the first body and extends into the installation cavity.

[0017] In this technical solution, the first sealing gasket also includes a second sealing portion, which is connected to the first body and extends into the installation cavity. Through the contact between the second sealing portion and the inner wall of the second shell, the sealing effect between the fixing part and the second shell is better, thereby improving the sealing of the terminal cover and further improving the explosion-proof performance of the terminal.

[0018] In some technical solutions of the present invention, optionally, a protrusion is provided on one side of the second shell close to the fixing member, and the protrusion is arranged around the installation cavity and abuts against the first body.

[0019] In this technical solution, a raised structure is provided on the side of the second housing near the fixing member. This structure surrounds the mounting cavity and contacts the first housing. The raised structure of the second housing is designed to increase pressure at a localized location, creating a sufficient pressure between the first sealing gasket and the raised location. This creates a tighter seal between the first gasket and the raised structure, enhancing the required waterproof and dustproof properties of the terminal cover and further improving the sealing performance of the terminal cover. Furthermore, the raised structure's contact with the first housing further enhances the explosion-proof performance of the terminal block.

[0020] Specifically, the protrusions arranged around the installation cavity may have a polygonal shape such as a circle, an ellipse, a square, a rectangle, or the like.

[0021] At the same time, the height of the protrusions arranged around the installation cavity should not exceed the thickness of the first body.

[0022] In some technical solutions of the present invention, optionally, the terminal cover further includes a plurality of welding points, and the plurality of welding points are arranged at intervals along the edge where the fixing member contacts the first housing.

[0023] In this technical solution, the terminal cover also includes multiple weld points, spaced along the edge where the fixing member contacts the first housing, securing the fixing member to the first housing. These weld points also minimize heat-induced deformation of the first housing and fixing member, improving the sealing reliability of the terminal cover and enhancing the explosion-proof performance of the terminal block.

[0024] In some technical solutions of the present invention, the terminal cover may optionally further include a cover plate and a second sealing gasket. The cover plate is arranged on a side of the installation cavity away from the fixing member; and the second sealing gasket is arranged between the cover plate and the second housing.

[0025] In this technical solution, the terminal cover also includes a cover plate and a second sealing gasket. The cover plate is positioned at the top of the mounting cavity, with the second sealing gasket interposed between the cover plate and the second housing. The cover plate and the second sealing gasket cooperate to seal the mounting cavity. Furthermore, the terminal cover facilitates assembly of the cables and terminal blocks, improving assembly efficiency.

[0026] Specifically, the first sealing gasket and the second sealing gasket can be made of rubber, silicone, EPDM or other materials.

[0027] Furthermore, a second protrusion may be provided on a side of the cover plate adjacent to the second sealing gasket. The second protrusion is arranged around the mounting cavity and abuts against the second sealing gasket. The second protrusion of the cover plate is configured to increase the pressure at a local location, so that a sufficiently high pressure is exerted on the second sealing gasket and the second protrusion, thereby making the second sealing gasket more tightly fitted, thereby enhancing the required waterproof and dustproof properties of the terminal cover, further improving the sealing performance of the terminal cover, and enhancing the explosion-proof performance of the terminal block.

[0028] In some technical solutions of the present invention, optionally, the terminal cover further includes a connector, which is passed through the cover plate, the second sealing gasket and the second shell, and is connected to the fixing member.

[0029] In this technical solution, the terminal cover also includes a connector that penetrates the cover plate, the second sealing gasket, and the second housing and is connected to the fixing member. By connecting the connector to the fixing member, rather than to the first housing, deformation of the connector caused by heating of the first housing is avoided. Furthermore, the fixing of the connector strengthens the overall structure of the terminal cover, enhances the sealing effect of the terminal cover, and improves the explosion-proof performance of the terminal block.

[0030] In some technical solutions of the present invention, optionally, the connecting member is a threaded member, and the terminal cover further includes a mounting member, which is arranged on the fixing member, and the mounting member is provided with a threaded hole, and the threaded member is screwed into the threaded hole.

The mounting part is provided with a threaded hole. The threaded part is screwed into the threaded hole, and the terminal cover is fixed to the first shell through the threaded connection, thereby ensuring the sealing of the terminal cover.

[0032] Optionally, the terminal cover is fixed to the first housing in a threaded connection manner, and other connection manners may also be used, such as a groove connection, a socket connection, and the like.

[0033] In some technical solutions of the present invention, optionally, the first body is provided with a second mounting hole, and the mounting piece is embedded in the second mounting hole.

[0034] In this technical solution, the first body is provided with a second mounting hole, into which the mounting member is inserted. By providing the second mounting hole in the first body, the connecting member and the mounting member are fixed without taking up additional space, simplifying the overall structure of the terminal cover and reducing the size of the terminal cover, making the terminal cover more compact.

[0035] In some technical solutions of the present invention, optionally, a wire outlet hole is provided on the side wall of the second shell, and the terminal cover also includes a cable and a wire sheath, the cable is connected to the wiring terminal and extends from the wire outlet hole to the outside of the second shell; the wire sheath is clamped in the wire outlet hole and is sleeved on the cable.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0051] Refer to the following Figures 1 to 6A terminal cover 100 , a compressor 300 , and a refrigeration device according to some embodiments of the present invention are described.

[0052] The first aspect of the present invention provides a terminal cover 100, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the terminal cover 100 is used for the compressor 300, which includes a first housing 310. The terminal cover 100 includes: a fixing member 110, a first sealing gasket 120, a second housing 130 and a terminal 140. The fixing member 110 is arranged on the first housing 310 and is provided with a first mounting hole 112. The first sealing gasket 120 includes a first body 122 and a first sealing portion 124. The first body 122 is arranged on a side of the fixing member 110 away from the first housing 310 and is arranged around the first mounting hole 112. The first sealing portion 124 is connected to the first body 122, is located in the first mounting hole 112, and extends toward the first housing 310. The second housing 130 is arranged on a side of the first body 122 away from the fixing member 110. The second housing 130 has a mounting cavity 134, which is connected to the first mounting hole 112. The terminal 140 is arranged on the first housing 310 and is located in the first mounting hole 112 and the mounting cavity 134.

[0053] In this embodiment, a terminal cover 100 suitable for a compressor 300 is proposed, and the terminal cover 100 includes a fixing member 110, a first sealing gasket 120, a fixing member 110, a second shell 130 and a terminal 140. The fixing member 110 is arranged on the first shell 310 of the compressor 300, and the fixing member 110 is provided with a first mounting hole 112. The first mounting hole 112 is used to facilitate the installation of internal parts of the terminal cover 100. The first sealing gasket 120 of the terminal cover 100 includes a first body 122 and a first sealing portion 124. The first sealing gasket 120 is used to seal the terminal cover 100. The first body 122 is arranged around the first mounting hole 112 and is located on the side of the fixing member 110 away from the first shell 310, thereby ensuring the sealing between the fixing member 110 and the second shell 130. The first sealing portion 124 is connected to the first body 122 and is located within the first mounting hole 112. The first sealing portion 124 extends toward the first housing 310, so that the fixing member 110 and the first housing 310 are sealed by the first sealing portion 124. The second housing 130 of the terminal cover 100 is disposed on a side of the first body 122 away from the fixing member 110. The second housing 130 has a mounting cavity 134 that communicates with the first mounting hole 112 to facilitate installation of components within the terminal cover 100. The terminal 140 of the terminal cover 100 is disposed on the first housing 310 and is located within the first mounting hole 112 and the mounting cavity 134. The provision of the first mounting hole 112 and the mounting cavity 134 facilitates connection of the terminal 140 within the terminal cover 100. In this application, the first sealing portion 124 is extended toward the first shell 310, so that the first sealing portion 124 is used to complete the sealing between the fixing member 110 and the first shell 310, thereby achieving the sealing between the terminal cover 100 and the first shell 310, thereby isolating the connecting terminal 140 in the terminal cover 100 from the outside air, thereby improving the explosion-proof performance of the connecting terminal 140.

[0054] The terminal cover 100 defined in the present invention extends toward the first shell 310 through the first sealing portion 124, thereby realizing sealing between the terminal cover 100 and the first shell 310. As a result, it is no longer necessary to achieve sealing by welding the contact area between the fixing member 110 and the first shell 310 as a whole, thereby reducing the heat generated when the terminal cover 100 and the first shell 310 are welded, thereby reducing the deformation of the first shell 310 and the fixing member 110 caused by heat, improving the reliability of the sealing between the terminal cover 100 and the first shell 310, and making the connection terminals 140 in the terminal cover 100 better isolated from the outside air.

[0055] Furthermore, by positioning the connection terminals 140 within the first housing 310 and within the first mounting hole 112 and mounting cavity 134, the present invention isolates the connection terminals 140 from the external environment, protecting them from damage by external forces. Furthermore, this isolation reduces the risk of water and dust intrusion, improving their reliability. This prevents short circuits between the connection terminals 140 and any adverse effects on electrical connection performance caused by water or dust, thereby improving the device's operating efficiency and service life.

[0056] At the same time, the present invention avoids contact accidents by isolating the connection terminal 140 from the external environment, thereby ensuring the safety of operators and users.

[0058] In this embodiment, the first sealing portion 124 extends toward the first housing 310, so that the first sealing gasket 120 contacts the first housing 310. The first sealing portion 124 contacts the first housing 310, thereby isolating the interior of the terminal cover 100 from the exterior, thereby improving the explosion-proof performance of the terminal block 140.

[0059] Optionally, the first sealing portion 124 may also contact the insulating plate and other components of the terminal block 140. By contacting the first sealing portion 124 with the insulating plate and other components of the terminal block 140, the internal space of the terminal cover 100 is isolated from the external space, thereby improving the explosion-proof performance of the terminal block 140.

[0060] In some embodiments of the present invention, optionally, as Figure 1 and Figure 2 As shown, the first sealing gasket 120 further includes a second sealing portion 126 , which is connected to the first body 122 and extends into the mounting cavity 134 .

[0063] In this embodiment, a protrusion 132 is provided on the side of the second housing 130 near the fixing member 110. This structure surrounds the mounting cavity 134 and contacts the first body 122. Protrusion 132 of the second housing 130 is designed to increase pressure at a local location, creating a sufficiently high pressure between the first sealing gasket 120 and the protrusion 132. This creates a tighter fit between the first sealing gasket 120, enhancing the required waterproof and dustproof properties of the terminal cover 100 and further improving the sealing performance of the terminal cover 100. Furthermore, the contact between protrusion 132 and the first body 122 further enhances the explosion-proof performance of the terminal block 140.

[0064] Specifically, the protrusions 132 arranged around the mounting cavity 134 may be in a polygonal shape such as a circle, an ellipse, a square, or a rectangle.

[0065] At the same time, the height of the protrusions 132 arranged around the mounting cavity 134 should not exceed the thickness of the first body 122 .

Furthermore, the spaced-apart arrangement of the plurality of welding points 150 reduces deformation of the first housing 310 and the fixing member 110 due to excessive heat, thereby improving the sealing reliability of the terminal cover 100 and enhancing the explosion-proof performance of the terminal block 140.
