Description

Technical Field

[0001] This utility model relates to the technical field of terminal protection, and in particular to an anti-condensation device for terminal blocks and an air conditioner formed therefrom. Background Technology

[0002] Floor-standing air conditioners typically employ a distributed airflow technology, with both upper and lower air outlets opening simultaneously when the indoor ambient temperature differs significantly from the target temperature for rapid cooling. When the indoor ambient temperature is close to the target temperature, only the upper air outlet opens, directing cool air along the ceiling for a gentle, refreshing cooling effect. Similarly, during carpet-like heating, both upper and lower air outlets open simultaneously to quickly achieve a constant temperature in the space. In contrast, floor-standing air conditioners, due to the need for efficient wiring, contain multiple terminals during cooling and heating. When cold air comes into contact with these terminals, condensation forms. If this condensation seeps into the terminals, it can cause short circuits when power is applied, severely impacting product quality and reliability.

[0003] In the prior art, the following method is usually used to protect the terminals from condensation: the terminals of the electrical box are plugged into the terminals of the air outlet frame, and a sponge is taken and wrapped around the outside of the terminals after plugging. The water absorption of the sponge is used to prevent condensation from entering the cavity and surface of the terminals. However, the method of attaching the terminals with sponge has problems such as sponge falling off and losing adhesion during long-term use. Moreover, when there is a lot of condensation, it can still seep into the inside of the terminals through the sponge, which cannot achieve effective protection for the terminals. Utility Model Content

[0004] To overcome the problems existing in related technologies, one of the objectives of this utility model is to provide a terminal block anti-condensation device. While achieving electrical connection, the device uses a protective box to protect the terminal block, preventing it from being corroded by condensate in alternating hot and cold environments, thus improving the service life of the terminal block and avoiding short circuits caused by contact with condensate.

[0005] A terminal block anti-condensation device for protecting terminal blocks; comprising:

[0006] Protective box,

[0007] Terminal clips located inside the protective box for securing wiring terminals;

[0008] A wire clip through-hole is located in the side wall of the protective box for fixing the wire; one end of the wire is connected to the terminal block, and the other end of the wire extends from the wire clip through-hole to the outside of the protective box.

[0009] This application achieves electrical connection while using a protective box to protect the terminals, preventing them from being corroded by condensation in alternating hot and cold environments, thus improving the service life of the terminals and preventing short circuits caused by contact with condensation.

[0010] In a preferred embodiment of this utility model, the protective box includes a box body and a protective cover. The terminal latching part is located inside the box body, and the wire latching through hole is located on the side wall of the box body. An opening is provided in the box body. One end of the protective cover is hinged to the box body, and the other end of the protective cover is detachably connected to the box body by a buckle. The protective cover can completely cover the opening.

[0011] This application features a flip-top protective cover for easy opening and closing of the housing. When the cover is rotated away from the housing, the housing is open, allowing the terminals to be engaged or disengaged from the terminal engagement section. When the terminals are in operation, the cover rotates to abut against the housing and is secured with a latch, creating a sealed environment inside the housing. The flip-top design and latching mechanism facilitate the insertion and removal of terminals while providing a secure seal for the internal terminals.

[0012] In a preferred embodiment of this invention, the protective box further includes a snap-fit ​​plate, the snap-fit ​​plate and the protective cover are disposed on opposite sides of the box body, the snap-fit ​​plate is provided with a snap-fit ​​groove, and the protective cover is provided with a buckle at the end away from the box body.

[0013] This application provides a snap-fit ​​plate and a protective cover on opposite sides of the box body. The snap-fit ​​plate is fixed to the box body and has a snap-fit ​​groove. One end of the protective cover is hinged to the box body, and the other end has a buckle that matches the snap-fit ​​groove. When the buckle rotates with the protective cover to the snap-fit ​​plate position, external force causes the buckle to engage with the snap-fit ​​groove, achieving a seal on the box body. When the box body needs to be opened, external force causes the buckle to disengage from the snap-fit ​​groove, and the protective cover can then be rotated. This application places the snap-fit ​​groove in the snap-fit ​​plate outside the box body, which does not affect the overall sealing of the box body. It ensures that when the protective cover and snap-fit ​​plate are engaged, the protective cover completely covers the opening in the box body, ensuring the internal sealing of the box body.

[0014] In a preferred embodiment of this invention, the housings are two arranged side by side, and the terminal latching part is located at the connection between the two housings.

[0015] In this application, the terminal block consists of two plug-in terminals, both of which require wire leads. Positioning the terminal latch at the junction of the two housings ensures sufficient space on both sides of the terminal block for easy placement of the two terminals and wire leads. In practice, the first and second terminals are plugged in to form the terminal block. When the terminal block is fixed in the terminal latch, the first terminal is located inside one housing, and the second terminal is located inside the other, ensuring proper placement of both terminals and preventing excessive bending of the wires connected to them.

[0016] In a preferred embodiment of this invention, the terminal latching portion includes a terminal latching through hole and a terminal latching groove, the terminal latching through hole being located at the center of the terminal latching groove, and the terminal latching groove being adapted to the wiring terminal.

[0017] In practice, the first and second terminals are plugged together to form a terminal block. The terminal locking groove in this application is used to place the terminal block. The reason for also providing a terminal locking through-hole is that the insertion points of the two terminals require penetration through the terminal locking through-hole to achieve electrical connection. It can be understood that the first and second terminals are located within the terminal locking groove, and the insertion points of the first and second terminals are located within the terminal locking through-hole. This achieves separate locking of the first and second terminals and proper placement of the insertion points, improving the stability of the terminal block.

[0018] In a preferred embodiment of this utility model, a connecting plate is provided at the connection point of the two boxes, and the terminal locking groove includes a first locking groove and a second locking groove, which are located on both sides of the connecting plate respectively; the wiring terminal includes a first wiring terminal and a second wiring terminal, which are inserted and fixed.

[0019] The first snap-fit ​​groove is adapted to the first terminal, and the second snap-fit ​​groove is adapted to the second terminal.

[0020] In this application, two housings are arranged side by side. At the connection between the two housings, the side wall of each housing can be used as a connecting plate, or the two housings can share a single connecting plate. When there are two connecting plates, the first and second snap-fit ​​grooves are located in the two connecting plates respectively, and terminal snap-fit ​​through holes are provided in the first and second snap-fit ​​grooves. When there is only one connecting plate, the first and second snap-fit ​​grooves are located on both sides of the connecting plate respectively. In this application, the first and second snap-fit ​​grooves are groove structures that do not penetrate the connecting plate, so they can be located on both sides of the same connecting plate, or on the side of two adjacent connecting plates that are far apart from each other. The first snap-fit ​​groove is adapted to the first terminal and is used to accommodate and snap-fit ​​the first terminal. The second snap-fit ​​groove is adapted to the second terminal and is used to accommodate and snap-fit ​​the second terminal. This achieves separate snap-fit ​​of the first and second terminals, as well as proper placement of the first and second terminals at their insertion positions, improving the fixing stability of the terminals.

[0021] In a preferred embodiment of this invention, the wire clip connection hole is located on the side of the housing away from the terminal clip connection portion.

[0022] In this application, there are two housings, with the terminal block located between them. Specifically, for each housing, the terminal block is located on one side of the housing, and the side of the housing furthest from the terminal block is the opposite side of the housing. For example, if the housing is a cuboid structure and the terminal block is on the right side, then the wire connection hole in that housing is on the left side. Each housing has a wire connection hole located on the side opposite the terminal block. This provides space for connecting terminals and wires while ensuring that wires inside the housing do not require excessive bending and avoids wasting wire length, thus improving the rationality of the wire and terminal layout.

[0023] In a preferred embodiment of this invention, an outer box is provided on the outside of the box body.

[0024] The built-in box in this application can be used to secure the entire device to the air conditioner unit. For example, a connection through-hole is provided inside the built-in box. When installing the terminal block anti-condensation device in the air conditioner unit, the protective cover is first opened, and the terminal block anti-condensation device is installed in the air conditioner unit by passing fastening screws through the connection through-hole. When the protective cover is closed, the built-in box is concealed by the cover, improving the neat appearance of the terminal block anti-condensation device.

[0025] In a preferred embodiment of this invention, an inner box is provided inside the box body.

[0026] The external box is used to collect condensate on the outside of the box body. When installing the terminal anti-condensation device, the installation angle is adjusted so that the external box is located at the bottom of the terminal anti-condensation device. The external box includes a fixing component and a water collection groove. The fixing component is located inside the external box and is fixedly connected to the box body. A surrounding water collection groove is provided on the outside of the fixing component. A certain gap is reserved between the water collection groove and the box body so that the condensate on the outside of the box body can flow into the water collection groove under the action of gravity.

[0027] The second objective of this application is to provide an air conditioner, including a terminal block anti-condensation device as described above, wherein the terminal block anti-condensation device is located at the air outlet frame of the air conditioner.

[0028] The beneficial effects of this utility model are as follows:

[0029] This utility model provides a terminal block anti-condensation device for protecting terminal blocks. Specifically, it includes a protective box, a terminal latching part inside the protective box for fixing the terminal block, and a wire latching through hole in the side wall of the protective box for fixing wires. One end of the wire is connected to the terminal block, and the other end of the wire extends from the wire latching through hole to the outside of the protective box. In this application, the terminal block is fixed in the terminal latching part after electrical connection, and the wire connected to the terminal block is latched in the wire latching through hole. Since the terminal latching part is located inside the protective box, even if the protective box is in an environment with alternating hot and cold temperatures, condensate will only condense on the outer wall of the protective box and will not seep into the terminal block. Simultaneously, the wire electrically connected to the terminal block extends out through the wire latching through hole on the side wall of the protective box. While achieving electrical connection, the protective box protects the terminal block, preventing it from being corroded by condensate in alternating hot and cold environments, thus improving the service life of the terminal block and preventing short circuits caused by contact with condensate.

[0030] This application also provides an air conditioner, including a terminal block anti-condensation device as described above, wherein the terminal block anti-condensation device is located at the air outlet frame of the air conditioner. While achieving electrical connection, the protective box provides protection for the terminal block, preventing it from being corroded by condensate in alternating hot and cold environments, thus improving the service life of both the terminal block and the air conditioner, and ultimately ensuring the stable operation of the air conditioner.

[0040] Example 1

[0041] like Figures 1-5 As shown, this application provides a terminal block anti-condensation device for protecting terminal blocks; it includes:

[0042] Protective box,

[0043] Terminal clips located inside the protective box for securing wiring terminals;

[0044] A wire clip through-hole 14 is located in the side wall of the protective box for fixing the wire; one end of the wire is connected to the terminal block, and the other end of the wire extends from the wire clip through-hole 14 to the outside of the protective box.

[0045] In this application, the wiring terminal (not shown in the figure) is formed by plugging in two terminals. For example, the wiring terminal of the electrical box is the first terminal, and the wiring terminal of the air outlet frame in the air conditioner is the second terminal. The first and second terminals are plugged together to form an electrical connection between the electrical box and the air outlet frame of the air conditioner. This plugged-in wiring terminal is located at the air outlet of the air conditioner, where there will be alternating hot and cold air. Cool air condenses at the warmer wiring terminal, forming condensate. To avoid the condensate affecting the wiring electronics, this application embeds the wiring terminal inside a protective box.

[0046] Except for the wire clip connection hole 14, the entire area of ​​the protective box is sealed, which can further prevent condensation from entering the interior of the protective box and improve the protection effect.

[0047] In this application, there are typically two wire clip through holes 14, each used to lead out the wires from the two terminals. For example, the wire connected to the first terminal is led out through one of the wire clip through holes 14, and the wire connected to the second terminal is led out through the other wire clip through hole 14. This is because the wires connected to the two terminals need to extend to different locations for electrical connection, so leading them out separately can maximize the sealing of the wire clip through holes 14.

[0048] When the wire is inserted into the wire clip through hole 14, a flexible buffer material, such as sponge or rubber, can be wrapped around the outside of the wire to make the wire and the wire clip through hole 14 form an interference fit, further ensuring the sealing performance of the protective box.

[0049] In this application, the terminal block is fixed in the terminal latch after electrical connection. The wire connected to the terminal block is latched in the wire latch through hole 14. Since the terminal latch is located inside the protective box, even if the protective box is in an environment of alternating hot and cold, condensate will only condense on the outer wall of the protective box and will not seep into the terminal block. At the same time, the wire connected to the terminal block extends out through the wire latch through hole 14 on the side wall of the protective box. While realizing electrical connection, the protective box forms protection for the terminal block, preventing the terminal block from being corroded by condensate in an environment of alternating hot and cold, improving the service life of the terminal block, and avoiding short circuit problems caused by contact with condensate.

[0050] Example 2

[0051] like Figures 1-5 As shown, this application provides a terminal block anti-condensation device for protecting terminal blocks; it includes:

[0052] Protective box,

[0053] Terminal clips located inside the protective box for securing wiring terminals;

[0054] A wire clip through-hole 14 is located in the side wall of the protective box for fixing the wire; one end of the wire is connected to the terminal block, and the other end of the wire extends from the wire clip through-hole 14 to the outside of the protective box.

[0055] Specifically, the protective box includes a box body 11 and a protective cover 15. The terminal latch is located inside the box body 11, and the wire latching hole 14 is located on the side wall of the box body 11. An opening is provided in the box body 11. One end of the protective cover 15 is hinged to the box body 11, and the other end of the protective cover 15 is detachably connected to the box body 11 through a buckle 17. The protective cover 15 can completely cover the opening.

[0056] This application provides a flip-top protective cover 15 for easy opening and closing of the housing 11. When the protective cover 15 is rotated away from the housing 11, the housing 11 is in the open state, allowing the wiring terminals to be engaged in or removed from the terminal engagement part. When the wiring terminals are in operation, the protective cover 15 rotates to a position abutting against the housing 11, and a snap-fit ​​17 secures the cover to the housing 11, creating a sealed environment inside the housing 11. The flipping of the protective cover 15 and the snap-fit ​​between the cover 15 and the housing 11 facilitate the insertion and removal of the wiring terminals while providing a sealed protection for the wiring terminals inside the housing 11.

[0057] Specifically, the protective box also includes a snap-fit ​​plate 16, the snap-fit ​​plate 16 and the protective cover 15 are disposed on opposite sides of the box body 11, the snap-fit ​​plate 16 is provided with a snap-fit ​​groove 18, and the protective cover 15 is provided with a buckle 17 at the end away from the box body 11.

[0058] This application provides a snap-fit ​​plate 16 and a protective cover 15 on opposite sides of the box body 11. The snap-fit ​​plate 16 is fixed to the box body 11 and has a snap-fit ​​groove 18. One end of the protective cover 15 is hinged to the box body 11, and the other end has a buckle 17 that matches the snap-fit ​​groove 18. When the buckle 17 rotates with the protective cover 15 to the position of the snap-fit ​​plate 16, external force causes the buckle 17 to engage with the snap-fit ​​groove 18, thus sealing the box body 11. When the box body 11 needs to be opened, external force causes the buckle 17 to disengage from the snap-fit ​​groove 18, and the protective cover 15 can be rotated. This application places the snap-fit ​​groove 18 in the snap-fit ​​plate 16 outside the box body 11, which does not affect the overall sealing of the box body 11. It ensures that when the protective cover 15 and the snap-fit ​​plate 16 are engaged, the protective cover 15 can completely cover the opening in the box body 11, ensuring the sealing of the inside of the box body 11.

[0059] Specifically, there are two boxes 11 arranged side by side, and the terminal latch is located at the connection between the two boxes 11.

[0060] In this application, the terminal block is formed by two terminals plugged together, and both terminals need to be led out through wires. The terminal locking part is located at the connection point of the two housings 11, ensuring sufficient space on both sides of the terminal block for separate placement of the two terminals and lead-out of their wires. In actual operation, the first and second terminals are plugged together to form the terminal block. When the terminal block is fixed in the terminal locking part, the first terminal is located inside one housing 11, and the second terminal is located inside the other housing 11, ensuring that both the first and second terminals are properly placed and that the wires connected to the first and second terminals are not excessively bent.

[0061] Specifically, the terminal latching part includes a terminal latching through hole 12 and a terminal latching groove 13. The terminal latching through hole 12 is located at the center of the terminal latching groove 13, and the terminal latching groove 13 is adapted to the wiring terminal.

[0062] In actual operation, the first and second terminals are plugged together to form a terminal block. The terminal locking groove 13 in this application is used to place the terminal block. The reason for also providing a terminal locking through hole 12 is that the insertion points of the two terminals require penetration through the terminal locking through hole 12 to achieve electrical connection. It can be understood that the first and second terminals are located within the terminal locking groove 13, and the insertion points of the first and second terminals are located within the terminal locking through hole 12. This achieves separate locking of the first and second terminals and proper placement of the insertion points of the first and second terminals, improving the stability of the terminal block.

[0063] Specifically, a connecting plate is provided at the connection point of the two boxes 11, and the terminal locking groove 13 includes a first locking groove and a second locking groove, which are located on both sides of the connecting plate respectively; the wiring terminal includes a first wiring terminal and a second wiring terminal, which are inserted and fixed; the first locking groove is adapted to the first wiring terminal, and the second locking groove is adapted to the second wiring terminal.

[0064] In this application, two housings 11 are arranged side by side. At the connection between the two housings 11, the side wall of each housing 11 can be used as a connecting plate, or the two housings 11 can share a single connecting plate. When there are two connecting plates, the first and second snap-fit ​​grooves are located in the two connecting plates respectively, and terminal snap-fit ​​through holes 12 are provided in the first and second snap-fit ​​grooves. When there is only one connecting plate, the first and second snap-fit ​​grooves are located on both sides of the connecting plate respectively. In this application, the first and second snap-fit ​​grooves are groove structures that do not penetrate the connecting plate, so they can be located on both sides of the same connecting plate, or on the side of two adjacent connecting plates that are far apart from each other. The first snap-fit ​​groove is adapted to the first terminal and is used to accommodate and snap-fit ​​the first terminal. The second snap-fit ​​groove is adapted to the second terminal and is used to accommodate and snap-fit ​​the second terminal. This achieves separate snap-fit ​​of the first and second terminals, as well as proper placement of the first and second terminals at their insertion positions, improving the fixing stability of the terminals.

[0065] Specifically, the wire clip connection hole 14 is located on the side of the housing 11 away from the terminal clip connection portion.

[0066] In this application, there are two housings 11, with the terminal latch located between the two housings 11. Specifically, for each housing 11, the terminal latch is located on one side of the housing 11, and the side of the housing 11 furthest from the terminal latch is the opposite side of the housing 11. For example, if the housing 11 is a cuboid structure and the terminal latch is located on the right side of the housing 11, then the wire latching hole 14 in that housing 11 is located on the left side of the housing 11. Each housing 11 is provided with a wire latching hole 14, and the wire latching hole 14 is located on the side of the housing 11 opposite to the side of the housing 11 where the terminal latch is located. This provides space for the connection of the terminals and wires, ensures that the wires inside the housing 11 do not need excessive bending, and avoids wasting wire length, thus improving the rationality of the wire and terminal layout.

[0067] Example 3

[0069] A protective box includes a box body 11 and a protective cover 15. The terminal latching part is located inside the box body 11, and the wire latching through hole 14 is located on the side wall of the box body 11. An opening is provided in the box body 11. One end of the protective cover 15 is hinged to the box body 11, and the other end of the protective cover 15 is detachably connected to the box body 11 through a buckle 17. The protective cover 15 can completely cover the opening.

[0070] Terminal clips located inside the protective box for securing wiring terminals;

[0071] A wire clip through-hole 14 is located in the side wall of the protective box for fixing the wire; one end of the wire is connected to the terminal block, and the other end of the wire extends from the wire clip through-hole 14 to the outside of the protective box.

[0072] In a first specific embodiment, a built-in box 20 is provided inside the housing 11. In this application, the built-in box 20 can be used to fix the entire device to the air conditioner unit. For example, a connecting through hole is provided inside the built-in box 20. When installing the terminal block anti-condensation device in the air conditioner unit, the protective cover 15 is first opened, and the terminal block anti-condensation device is installed in the air conditioner unit by passing a fastening screw through the connecting through hole. When the protective cover 15 is closed, the built-in box 20 is covered by the protective cover 15, improving the neat appearance of the terminal block anti-condensation device.

[0073] In a second specific embodiment, an external box 19 is provided on the outside of the housing 11. The external box 19 can be used to fix the entire device to the air conditioner unit. For example, the internal box 20 is provided with a connecting through hole. When the terminal anti-condensation device is installed in the air conditioner unit, the terminal anti-condensation device is installed in the air conditioner unit by fastening screws through the connecting through hole.

[0074] In a second specific embodiment, an inner box 20 is provided inside the box body 11, and an outer box 19 is provided outside the box body 11. In this application, the inner box 20 can be used to fix the entire device to the air conditioner unit. For example, a connecting through hole is provided inside the inner box 20. When installing the terminal block anti-condensation device in the air conditioner unit, the protective cover 15 is first opened, and the terminal block anti-condensation device is installed in the air conditioner unit by passing a fastening screw through the connecting through hole. When the protective cover 15 is closed, the inner box 20 is covered by the protective cover 15, improving the neat appearance of the terminal block anti-condensation device. Meanwhile, the outer box 19 is used to collect condensate on the outside of the box body 11; such as... Figure 4As shown, when installing the terminal block anti-condensation device, the installation angle is adjusted so that the external box 19 is located at the bottom of the terminal block anti-condensation device. The external box 19 includes a fixing member 21 and a water collection groove 22. The fixing member 21 is located inside the external box 19 and is fixedly connected to the box body 11. A surrounding water collection groove 22 is provided on the outside of the fixing member 21. A certain gap is reserved between the water collection groove 22 and the box body 11 so that the condensate on the outside of the box body 11 can flow into the water collection groove 22 under the action of gravity.

The structure after the first and second wiring terminals are plugged in is referred to as the wiring terminal in this embodiment. The wiring terminal is fixed inside the anti-condensation device for the wiring terminal.

[0078] The terminal block anti-condensation device is used to protect the terminal block; specifically, it includes a protective box, which includes a box body 11, a protective cover 15, and a snap-fit ​​plate 16. The box body 11 has an opening; one end of the protective cover 15 is hinged to the box body 11, and the other end of the protective cover 15 is detachably connected to the box body 11 via a snap-fit ​​17. The protective cover 15 can completely cover the opening.

[0079] A snap-fit ​​plate 16 and a protective cover 15 are respectively provided on opposite sides of the box body 11. The snap-fit ​​plate 16 is fixed to the box body 11, and a snap-fit ​​groove 18 is provided in the snap-fit ​​plate 16. One end of the protective cover 15 is hinged to the box body 11, and the other end is provided with a buckle 17 that matches the snap-fit ​​groove 18. When the buckle 17 rotates with the protective cover 15 to the position of the snap-fit ​​plate 16, the buckle 17 is engaged into the snap-fit ​​groove 18 by external force, thereby sealing the box body 11. When the box body 11 needs to be opened, the buckle 17 is disengaged from the snap-fit ​​groove 18 by external force, and the protective cover 15 can be rotated.

[0080] The box body 11 consists of two parallel boxes with identical structures. The only difference is that the protective covers 15 in the two boxes 11 are installed opposite each other. For example, if the protective cover 15 of one box 11 is installed on the upper side, then the protective cover 15 of the other box 11 is installed on the lower side. Figure 1 As shown.

[0081] The terminal latching part is located at the connection between the two housings 11. A connecting plate is provided at the connection between the two housings 11. The terminal latching part includes a terminal latching through hole 12 and a terminal latching groove 13. The terminal latching through hole 12 is located at the center of the terminal latching groove 13. The terminal latching groove 13 is adapted to the wiring terminal.

[0082] Specifically, the terminal locking groove 13 includes a first locking groove and a second locking groove, which are located on both sides of the connecting plate, respectively. The wiring terminal includes a first terminal and a second terminal, which are inserted and fixed. The first locking groove is adapted to the first terminal, and the second locking groove is adapted to the second terminal. In this application, the wiring terminal is formed by inserting two terminals, and both terminals need to be led out through wires. Setting the terminal locking part at the connection position of the two housings 11 ensures that there is sufficient space on both sides of the wiring terminal to facilitate the separate placement of the two terminals and the lead-out of the wires from the two terminals. In actual operation, the first terminal and the second terminal are inserted to form the wiring terminal. When the wiring terminal is fixed in the terminal locking part, the first terminal is located inside one housing 11, and the second terminal is located inside the other housing 11, ensuring that both the first terminal and the second terminal can be properly placed, and that the wires connected to the first terminal and the second terminal are not excessively bent.

[0083] The protective box has a wire clip connection hole 14 in its side wall for fixing wires; one end of the wire is connected to the terminal block, and the other end of the wire extends from the wire clip connection hole 14 to the outside of the protective box. The wire clip connection hole 14 is located on the side of the box 11 away from the terminal block connection. That is, each box 11 has a wire clip connection hole 14, and the wire clip connection hole 14 is located on the side of the box 11 opposite to the side where the terminal block connection is located.

[0084] An inner box 20 is provided inside the box body 11, and an outer box 19 is provided outside the box body 11. In this application, the inner box 20 can be used to fix the entire device to the air conditioner unit. For example, a connecting through hole is provided inside the inner box 20. When installing the terminal block anti-condensation device in the air conditioner unit, the protective cover 15 is first opened, and the terminal block anti-condensation device is installed in the air conditioner unit by passing a fastening screw through the connecting through hole. When the protective cover 15 is closed, the inner box 20 is covered by the protective cover 15, improving the neat appearance of the terminal block anti-condensation device. Meanwhile, the outer box 19 is used to collect condensate water from the outside of the box body 11; such as... Figure 4As shown, when installing the terminal block anti-condensation device, the installation angle is adjusted so that the external box 19 is located at the bottom of the terminal block anti-condensation device. The external box 19 includes a fixing member 21 and a water collection groove 22. The fixing member 21 is located inside the external box 19 and is fixedly connected to the box body 11. A surrounding water collection groove 22 is provided on the outside of the fixing member 21. A certain gap is reserved between the water collection groove 22 and the box body 11 so that the condensate on the outside of the box body 11 can flow into the water collection groove 22 under the action of gravity.

[0085] This application achieves electrical connection while using a protective box to protect the wiring terminals, preventing them from being corroded by condensate in the alternating hot and cold environment at the air outlet frame. This improves the service life of the wiring terminals and the air conditioner, thereby ensuring the stable operation of the air conditioner.
