[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] like Figure 1 As shown, an embodiment of the present invention provides an anti-condensation cable grounding box, which includes a box body 100 and electrical components disposed inside the box body 100.

[0035] Combination Figure 1 and Figure 2 The box 100 includes a box body and a storage shell 120 disposed inside the box body. The box body includes a side panel assembly 110, a box door 130, a box cover 140, and a bottom plate assembly 150.

[0036] Specifically, the side panel assembly 110 includes a plurality of interconnected side panels 1101; the door 130 is rotatably connected to the side panel assembly 110 and can be opened or closed; the lid 140 covers the top of the side panel assembly 110; the bottom panel assembly 150 is connected to the bottom of the side panel assembly 110; and the storage shell 120 is disposed inside the main body of the box, wherein the storage shell 120 can be used to install some electrical components, such as intelligent processing devices.

[0037] like Figure 3 As shown, the storage shell 120 includes a bottom shell 121 and a top cover 122. The bottom shell 121 has a shell opening, and the top cover 122 covers the shell opening and the edge of the top cover 122 is arranged around the edge of the shell opening.

[0038] Specifically, the bottom shell 121 is a hollow structure with a shell opening at the top, and the top cover 122 is used to cover the shell opening to seal it. The edge of the top cover 122 is set around the edge of the shell opening, which can further improve the sealing effect.

[0039] Furthermore, the upper surface of the cover 122 has a flow guiding structure 1221 and a drainage groove 1222 located on the lower side of the flow guiding structure 1221. The bottom wall of the drainage groove 1222 is provided with a drainage hole 1223. The drainage hole 1223 is separated from the internal space of the bottom shell 121, and the bottom of the drainage hole 1223 is a non-blocking structure.

[0040] Understandably, if condensation occurs inside the main body of the box due to temperature differences between day and night, when the condensation drips onto the top cover 122, it will enter the drainage groove 1222 along the guide structure 1221 and then be discharged through the drainage hole 1223. In this way, the risk of condensation entering the storage shell 120 and damaging the electrical components inside the storage shell 120 can be reduced.

[0041] like Figure 2 As shown, the storage shell 120 is disposed within the space enclosed by the side panel assembly 110 and located at the upper end of the side panel assembly 110, with the top cover 122 facing the box cover 140.

[0042] Understandably, the upper cover 122 acts as a separator, dividing the space between the bottom shell 121 and the lid 140. This separates the internal space of the bottom shell 121 from the internal space of the upper cover 122, effectively dividing a larger space into two smaller ones. Smaller spaces mean a smaller total air volume, consequently reducing the amount of water vapor they can hold. Furthermore, condensation is often related to temperature differences. When warm, humid air encounters a cooler surface, water vapor easily condenses into droplets. Reducing the space allows for a more uniform temperature distribution and reduces temperature gradients. Smaller spaces facilitate overall temperature balance, with weaker convection between cold and warm air, reducing the likelihood of localized excessively low or high temperatures and thus lowering the risk of water vapor condensation due to temperature differences.

[0043] It should be noted that the problem of condensation can also be further improved by adding multiple separators in the space between the bottom shell 121 and the cover 140.

[0044] Furthermore, the walls of the space formed by the lid 140 and the storage shell 120 are provided with insulating cotton. In this way, the rate of temperature change inside the box 100 can be slowed down, while also absorbing a small amount of condensation and reducing condensation dripping.

[0045] Combination Figure 3 and Figure 4 In some embodiments, the middle of the cover 122 is arched to form a flow guide structure 1221, and the drainage groove 1222 is provided on the side of the cover 122.

[0046] Specifically, the flow guiding structure 1221 includes an inclined first flow guiding surface 1221a and an inclined second flow guiding surface 1221b. The first flow guiding surface 1221a and the second flow guiding surface 1221b are arranged side by side, and the higher sides of the first flow guiding surface 1221a and the second flow guiding surface 1221b are close to the middle of the upper surface of the upper cover 122. The lower sides of the first flow guiding surface 1221a and the second flow guiding surface 1221b are respectively located on both sides of the upper cover 122. The drainage channel 1222 includes a first drainage channel 1222a disposed on the lower side of the first flow guiding surface 1221a and a second drainage channel 1222b disposed on the lower side of the second flow guiding surface 1221b.

[0047] It is understood that the bottom walls of both the first drainage trough 1222a and the second drainage trough 1222b are provided with drainage holes 1223. When condensation drips onto the upper surface of the cover 122, the condensation can enter the corresponding drainage trough 1222 along the first guide surface 1221a and / or the second guide surface 1221b, and be discharged through the drainage holes 1223 on the drainage trough 1222.

[0048] Furthermore, the bottom wall of the drainage channel 1222 can be inclined, and the drainage hole 1223 is located at the lower part of the bottom wall of the drainage channel 1222.

[0049] Furthermore, the bottom shell 121 is provided with a through hole opposite to the drain hole 1223, so as to prevent the bottom shell 121 from blocking the bottom end of the drain hole 1223.

[0050] like Figure 5 As shown, in some embodiments, the bottom shell 121 is provided with slots 1211 on both sides opposite to the shell opening, and the opposite sides of the top cover 122 are respectively engaged in the slots 1211 on both sides opposite to the shell opening. In this way, the top cover 122 can be fixed.

[0051] Combination Figure 2 , Figure 6 and Figure 7 In some embodiments, the side panel assembly 110 includes a plurality of side panels 1101, and at least one side panel 1101 is provided with a rainproof structure 1102. The rainproof structure 1102 includes a plurality of rainproof parts arranged along the direction of gravity. The rainproof parts include a deflector 11021 and a protective plate 11022. The top of the deflector 11021 is disposed near the inner side of the side panel 1101, and the deflector 11021 is gradually inclined towards the outer side of the side panel 1101 from top to bottom. The top of the protective plate 11022 is connected to the bottom of the deflector 11021.

[0052] It is understood that a rainproof structure 1102 can be provided on one of the side plates 1101, or on two or more side plates 1101. The rainproof structure 1102 includes multiple rainproof parts arranged from top to bottom, each rainproof part having the same structure; for each rainproof part: its guide plate 11021 is inclined, and the top of the guide plate 11021 is close to the inner side of the side plate 1101, and the bottom of the guide plate 11021 is close to the outer side of the side plate 1101. In other words, the guide plate 11021 is gradually inclined towards the outer side of the side plate 1101 from top to bottom; for each rainproof part: the top of its protective plate 11022 is connected to the bottom of the guide plate 11021, and its protective plate 11022 extends vertically downward from its top. In addition, in each pair of adjacent rainproof sections: the bottom of the protective plate 11022 of the upper rainproof section is disposed opposite to the outer wall of the guide plate 11021 of the lower rainproof section.

[0053] For each pair of adjacent rainproof sections: the bottom of the protective plate 11022 of the upper rainproof section is offset from the top of the guide plate 11021 of the lower rainproof section, and a removable baffle 11023 is provided between the bottom of the protective plate 11022 of the upper rainproof section and the top of the guide plate 11021 of the lower rainproof section.

[0054] Specifically, for each pair of adjacent rainproof sections: the bottom of the protective plate 11022 of the upper rainproof section and the top of the guide plate 11021 of the lower rainproof section are horizontally offset, and the baffle 11023 blocks the gap formed by the offset between the bottom of the protective plate 11022 of the upper rainproof section and the top of the guide plate 11021 of the lower rainproof section.

[0055] It should be noted that the baffle 11023 is configured to be broken so that a vent is formed between the bottom of the protective plate 11022 of the upper rainproof part and the top of the guide plate 11021 of the lower rainproof part.

[0056] Specifically, the baffle 11023 has a thin-walled structure, and its thickness can be set to be greater than or equal to 0.5 mm and less than or equal to 2 mm. In this way, the baffle 11023 can be knocked off or poked off by the staff with the help of tools, thereby forming a ventilation opening for connecting the interior of the enclosure 100 with the outside.

[0057] If the electrical components inside the anti-condensation cable grounding box do not require heat dissipation and ventilation, or if the area where it is installed is in a humid environment for a long time, then it is not necessary to remove the baffle 11023. The entire box 100 has a high sealing effect, which can reduce the risk of damage to the electrical components inside the box 100. If the electrical components inside require heat dissipation and ventilation, then the baffle 11023 can be removed to form a ventilation opening for ventilation. When the baffle 11023 is removed, in rainy weather, most of the rainwater will flow down the outer surface of the protective plate 11022 after falling onto the side plate 1101. A small amount will flow to the bottom surface of the protective plate 11022 and drip onto the guide plate 11021, and then flow down along the guide plate 11021. It is difficult for the rainwater to enter the interior of the box 100, thus also achieving the effect of preventing rain.

[0058] Combination Figure 5 and Figure 6 Furthermore, the side wall of the bottom shell 121 is provided with a removable closed window 1212 that is positioned opposite to the rainproof structure 1102.

[0059] Understandably, if ventilation and heat dissipation of the electrical components inside the storage housing 120 are not required, the closed window 1212 can remain intact; if ventilation and heat dissipation of the electrical components inside the storage housing 120 are required, the closed window 1212 can be removed, as can the baffle 11023, to facilitate ventilation.

[0060] It should be noted that multiple parallel horizontal grooves can be provided on the side wall of the bottom shell 121, which makes it easier to break this part of the side wall of the bottom shell 121.

[0061] In the anti-condensation cable grounding box of this utility model, if condensation occurs inside the main body of the box due to the temperature difference between day and night, when the condensation drips onto the top cover 122, the condensation will enter the drainage groove 1222 along the flow guiding structure 1221, and then be discharged through the drainage hole 1223. In this way, the risk of condensation entering the interior of the storage shell 120 and damaging the electrical components inside the storage shell 120 can be reduced.
