For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0027] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0028] Please see Figures 1 to 3 The rain cover for the relay junction box in the first embodiment of this utility model includes: a housing 1, and a locking assembly 2 for mounting the housing 1 onto the relay 3. The housing 1 includes: a cover 11 and at least one shielding member 12. The cover 11 has a groove 13 for accommodating the relay 3. The shielding member 12 is disposed on the cover 11 and has a receiving cavity 14 for wrapping the junction of the cable 4 and / or the air intake pipe 5 with the relay 3. The locking assembly 2 includes a limiting groove 21 on the cover 11, which cooperates with a bolt 6 on the relay 3 to clamp and lock the cover 11 onto the relay 3.

[0029] This application uses a groove 13 to fasten the entire rain cover onto the relay 3, allowing the upper part of the relay 3 to extend into the groove 13 for engagement. The side of the relay 3 and the groove 13 maintain a relatively stationary relationship between the rain cover and the relay 3, facilitating installation and improving efficiency. After the cover 11 is installed on the relay 3, the receiving cavity 14 on the shield 12 covers the junction of the cable 4 and / or the air intake pipe 5 with the relay 3, preventing water droplets from entering the relay 3 and improving sealing. This provides protection for the relay 3, cable 4, and air intake pipe 5, reducing environmental corrosion and extending their service life, resulting in more stable and longer operation.

[0030] The shielding member 12 can be detached and installed on the cover 11. The receiving cavity 14 of the shielding member 12 can be used to fit the cable 4 and / or the air intake pipe 5. After the cover 11 is installed on the relay 3, the shielding member 12 is then installed on the cover 11, so that the shielding member 12 surrounds the junction of the relay 3 and the cable 4 and / or the air intake pipe 5, which further improves the protection of the junction and extends the service life.

[0031] The limiting groove 21 on the cover 11 cooperates with the bolt 6 on the relay 3 to clamp and lock the cover 11 onto the relay 3. After the bolt 6 passes through the limiting groove 21 and is installed on the relay 3, tightening the bolt 6 will generate a clamping force between the bolt 6 and the relay 3, clamping the side of the cover 11 in the middle. The limiting groove 21 can prevent the cover 11 from shaking on the relay 3, further improving the connection strength between the cover 11 and the relay 3, avoiding noise generation, and making it suitable for more usage environments.

[0032] Please see Figures 1 to 3 In some embodiments, the shielding member 12 is provided with a first opening 15 communicating with the receiving cavity 14 in the direction away from the top of the cover 11.

[0033] This application provides a first opening 15 communicating with the receiving cavity 14 at the top of the shielding member 12, away from the top of the cover 11. The first opening 15 is located below the shielding member 12. When the cover 11 is fastened to the relay 3 using the groove 13, the cable 4 and / or the air intake pipe 5 can directly enter the receiving cavity 14 through the first opening 15, thereby improving the convenience and efficiency of installation and reducing operational difficulty. Because the first opening 15 is located below the shielding member 12, it also prevents water droplets from entering the receiving cavity 14, thus providing good sealing and protection. It also reduces the area of ​​the relay 3 being shielded, allowing the relay 3 to have good heat dissipation, thereby enabling the relay 3 to operate stably for a long time.

[0034] Please see Figures 1 to 4 In some embodiments, the limiting groove 21 is provided with a second opening 22 in the direction away from the top of the cover 11, allowing the bolt 6 to pass through.

[0035] This application provides a second opening 22 in the direction away from the top of the cover 11 via a limiting groove 21, allowing the bolt 6 to pass through. The second opening 22 is located below the limiting groove 21, ensuring that the bottom of the limiting groove 21 is unobstructed. When the cover 11 is fastened to the relay 3 using the groove 13, only the bolt 6 needs to be loosened to create a gap between the bolt 6 and the relay 3. The cover 11 can then fasten to the relay 3 using this gap, allowing the bolt 6 to slide into the limiting groove 21. This eliminates the need for operators to completely unscrew the bolt 6 when installing the rain cover, thereby improving installation efficiency, preventing the bolt 6 from being lost, and saving maintenance costs.

[0036] After the bolt 6 slides into the limiting groove 21, the mutual blocking between the limiting groove 21 and the bolt 6 can improve the stability of the cover 11 in the horizontal direction of the relay 3, thereby improving the stability after installation and making it suitable for more usage environments.

[0037] Please see Figures 1 to 3In some embodiments, the housing 1 further includes a drain member 16 disposed on the cover 11, the drain member 16 having a slope that slopes in all directions.

[0038] This application utilizes a drain element 16 mounted on the cover 11, which has inclined surfaces sloping outwards in all directions. Rain, snow, or other impurities falling onto the drain element 16 will slide down along these inclined surfaces, preventing them from remaining on the drain element 16 and causing corrosion. This extends the service life of the drain element 16 and reduces the load on the relay 3, thus enabling the relay 3 to maintain stable operation for a longer period and improving its stability.

[0039] Please see Figures 1 to 3 In some embodiments, the housing 1 further includes a guide 17 disposed on the inclined surface of the guide 16, and the guide 17 is disposed above the limiting groove 21 and the shield 12.

[0040] This application utilizes a guide 17 positioned on the inclined surface of the drain 16, correspondingly positioned above the limiting groove 21 and the shield 12. When rain, snow, or other impurities slide down the inclined surface, the guide 17 prevents them from falling above the limiting groove 21 and the shield 12, thus avoiding damage to the shield 12 and affecting the sealing and protection of the cable 4 and / or the air intake pipe 5. It also prevents rain, snow, or other impurities from falling into the gap between the cover 11 and the bolt 6, affecting the sealing of the relay 3, and prevents corrosion of the cover 11 and the bolt 6, thereby extending their service life.

[0041] The guide member 17 can be triangular, with the vertex of the triangle facing the center of the drain member 16 on the inclined surface. This triangular guide member 17 diverts rain, snow, or other impurities to the edge of the cover 11, thereby improving the sealing and protection at the junction of the relay 3 and the cable 4 and / or the air intake pipe 5. The diversion using the triangular guide member 17 further reduces the residue of rain, snow, or other impurities on the drain member 16 and the guide member 17, extending their service life and reducing the load on the relay 3.

[0042] Please see Figures 1 to 4 In some embodiments, the locking assembly 2 further includes a stop 23 detachably mounted on the cover 11, which closes the second opening 22 after the bolt 6 enters the limiting groove 21.

[0043] This application uses a stop 23 to close the second opening 22 after the bolt 6 enters the limiting groove 21. After the bolt 6 enters the limiting groove 21, the stop 23 passes through the cover 11. The stop 23 and the limiting groove 21 form a limiting cavity that encloses the bolt 6. The cooperation between the limiting cavity and the bolt 6 limits the cover 11 in the vertical direction, further improving the stability of the cover 11 on the relay 3.

[0044] Among them, the stop 23 can be a plug plate with a plug hole on the cover 11. After the bolt 6 enters the limiting groove 21, the plug plate is inserted into the plug hole, and then the bolt 6 is tightened. The side of the cover 11 and the plug plate are clamped between the bolt 6 and the relay 3, which improves stability and reduces the gap between the bolt 6 and the relay 3, preventing the intrusion of impurities and improving the stability of the relay 3 operation.

[0045] Please see Figures 1 to 4 In some embodiments, the locking assembly 2 further includes limiting bolts 24, and multiple limiting bolts 24 are installed on the cover 11 by threaded pairs, and multiple limiting bolts 24 extend into the groove 13 to contact the relay 3.

[0046] This application uses multiple limiting bolts 24, all of which are installed on the cover 11 via threaded joints. The multiple limiting bolts 24 extend into the groove 13 and contact the relay 3. The cooperation of the multiple limiting bolts 24 can press the cover 11 onto the relay 3, which further improves the connection strength between the cover 11 and the relay 3, reduces noise generation, and also improves stability.

[0047] The multiple limiting bolts 24 work together to clamp the cover 11 onto relays 3 of different models, thus expanding its applicability and facilitating installation. Furthermore, by changing the distance the front and rear limiting bolts 24 extend into the grooves 13, the distance between the front and rear inner walls of the cover 11 and the relay 3 can be altered. This allows for adjustments to the position of the cover 11 based on the site conditions, making it suitable for a wider range of installation environments.

[0048] Please see Figures 1 to 3 In some embodiments, the locking assembly 2 further includes a shield 25 disposed on the cover 11, the shield 25 covering the connection between the limiting bolt 24 and the cover 11.

[0049] This application uses a shield 25 to cover the connection between the limiting bolt 24 and the cover 11. The shield 25 provides a certain degree of sealing and protection at the connection between the limiting bolt 24 and the cover 11, preventing water droplets from entering the groove 13 through the gap between the limiting bolt 24 and the cover 11 and affecting the relay 3, thus further improving the protection of the relay 3. The shield 25 also prevents rainwater from corroding and rusting the limiting bolt 24, making it easier and less strenuous for operators to install and remove the limiting bolt 24, thereby improving the efficiency of installation and removal, extending the service life of the limiting bolt 24, and ensuring that the limiting bolt 24 can still provide a stable clamping effect on the cover 11 after long-term use.

[0050] Please see Figures 1 to 3 In some embodiments, the locking assembly 2 also includes straps or wires that wrap the housing 1 and the relay 3 together.

[0051] This application uses straps or wire to wrap the housing 1 and the relay 3 together. Using straps allows for a smoother and less strenuous wrapping of the housing 1 around the relay 3, further improving the stability of the housing 1 on the relay 3.

[0052] Using iron wire allows for a more stable and secure wrapping of the housing 1 around the relay 3. Iron wire has better corrosion resistance, which enables the housing 1 to be wrapped around the relay 3 stably for a long time, extending its service life and improving the stability of the housing 1 on the relay 3.

[0053] Please see Figures 1 to 3 In some embodiments, the shield 12 has a polygonal or arc-shaped cross-section. Or / and the cover 11 has a polygonal, circular, or partially arc-shaped cross-section.

[0054] This application utilizes a polygonal or arc-shaped cross-section for the shielding member 12. A polygonal shielding member 12 is easier to manufacture, reduces manufacturing costs, facilitates connection with the cover 11, and is easier to position during installation. An arc-shaped shielding member 12 prevents rain, snow, or other impurities from remaining, is less prone to deformation, provides better coverage, reduces wear on the cable 4 and / or the air intake pipe 5, and provides long-term, stable protection for the cable 4 and / or the air intake pipe 5.

[0055] This application utilizes a cover 11 with a cross-section that is polygonal, circular, or partially arc-shaped. A polygonal cross-section of the cover 11 allows it to be manufactured according to the shape of the relay 3, making the groove 13 of the cover 11 fit more closely to the outer surface of the relay 3, thereby improving the stability of the cover 11 after it is fastened.

[0056] The circular cross-section of the cover 11 provides better stress relief, reducing the pressure of rain, snow or wind on the cover 11, thereby reducing the pressure applied to the side of the relay 3, enabling the relay 3 to operate stably in complex environments and expanding its application range.

[0057] The cover 11 with a partially rounded cross-section can be designed to match the shape of the relay 3, making the groove 13 fit the outer surface of the relay 3 better, improving the stability after fastening, and also appropriately reducing the space occupied by the cover 11, making it suitable for more usage environments.

[0058] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
