Description

Technical Field

[0001] This application relates to the field of waterproofing technology for electrical equipment, specifically to a waterproofing system for wiring mechanisms and electrical equipment. Background Technology

[0002] Outdoor electrical equipment, such as charging piles for new energy vehicles, has cable outlets on the top. Internal cables pass through these outlets and connect to external equipment. The cables often need to be connected after passing through cable trays. Water accumulated in the cable trays or rainwater from outside can easily flow along the outer wall of the cables to the electrical equipment and enter the equipment through the cable outlets, causing equipment failure and safety hazards.

[0003] Therefore, how to prevent outdoor electrical equipment from malfunctioning or posing safety hazards due to external water flowing into the equipment along the cables is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this application is to provide a waterproof system for wiring structures and electrical equipment, which can prevent outdoor electrical equipment from malfunctioning or causing safety hazards due to external water flowing into the electrical equipment along the cables.

[0005] To solve the above-mentioned technical problems, this application provides a wiring mechanism, including a first lead portion, a connecting portion, and a second lead portion fixed to each other. The bottom of the first lead portion forms an electrical equipment connection end. The first lead portion is provided with a first lead cavity, the second lead portion is provided with a second lead cavity, and the connecting portion is provided with a connecting cavity. The connecting cavity connects the first lead cavity and the second lead cavity, and the connecting portion is located above the second lead portion.

[0006] The connecting part is located above the second lead part. After the cable passes through the first lead part, it passes through the connecting part located above, and then enters the second lead part located below before connecting to the external device. The height of the part of the cable inside the connecting part is higher than the height of the part inside the second lead part.

[0007] The cable has a first bending structure between the second lead portion and the connecting portion. The first bending structure is an inverted U-shaped or V-shaped structure with the opening facing downwards, and the highest point of the first bending structure is located inside the connecting portion.

[0008] This design allows water falling onto the cable surface to flow along the cable's outer wall to the second lead section. Due to gravity, it does not continue flowing along the cable surface into the connecting section, causing water on the cable's outer wall to accumulate in the second lead section. Since the second lead section is located below the connecting section, this prevents water from entering the connecting section, effectively preventing external water from entering the connecting section and the first lead section. This, in turn, prevents external water from entering the electrical equipment through the outlet hole, ensuring the normal operation of the electrical equipment and avoiding safety hazards caused by water ingress.

[0009] Optionally, the first wall portion of the first lead portion and the second wall portion of the second lead portion are attached and fixed together, and the height of the second wall portion is not higher than the height of the first wall portion.

[0010] Optionally, the connecting portion includes a connecting part one and a connecting part two connected together, the connecting part one being connected and fixed to the first lead portion, and the connecting part two being connected and fixed to the top end of the second lead portion.

[0011] Optionally, the bottom of the connecting portion and the second lead portion are respectively provided with mutually compatible positioning structures.

[0012] Optionally, the connecting portion is sleeved over the top end of the first lead portion and fixed to the first lead portion.

[0013] Optionally, the first lead portion is further provided with a wire-blocking portion on the side facing the electrical equipment connection end, and the wire-blocking portion forms the lowest bending point of the cable.

[0014] Optionally, the wire-blocking portion has a U-shaped structure, and the open end of the U-shaped structure forms a fixed end.

[0015] Optionally, the first lead portion includes a lead segment and a fixed segment connected in series, the lead segment is located between the fixed segment and the connecting portion, the fixed segment is provided with the electrical equipment connection end, and the wire blocking portion is located within the fixed segment.

[0016] This application also provides a waterproof system for electrical equipment, including electrical equipment and a wiring mechanism as described above. The electrical equipment connection end of the first lead portion is connected to the top of the electrical equipment. The cable of the electrical equipment passes through the top outlet hole and sequentially passes through the first lead portion, the connecting portion and the second lead portion of the wiring mechanism.

[0017] Optionally, a waterproof boss is provided at the top of the electrical equipment along the circumference of the outlet hole.

[0018] The waterproofing system for electrical equipment with the wiring mechanism described above has a similar technical effect to the wiring mechanism described above, and will not be described in detail here for the sake of brevity. Attached Figure Description

[0031] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] The top of the electrical equipment has a cable outlet. One end of the cable is connected to the electrical components inside the electrical equipment, and the other end passes through the cable outlet and is connected to external equipment. For outdoor electrical equipment, rainwater or water accumulation in the wiring structure can easily flow along the outer wall of the cable to the cable outlet and enter the electrical equipment, causing electrical equipment failure or safety hazards.

[0033] This application provides a waterproof system for wiring mechanisms and electrical equipment, wherein, as shown in the embodiments, Figure 1 and Figure 2As shown, the waterproof system of the electrical equipment includes the wiring mechanism of the electrical equipment 6. The wiring mechanism can ensure the waterproof performance of the top outlet hole 61 of the outdoor electrical equipment 6, and prevent the electrical equipment 6 from malfunctioning or causing safety hazards due to water entering the top outlet hole 61 of the electrical equipment 6.

[0034] Specifically, the wiring mechanism includes a first lead portion 1, a connecting portion 2, and a second lead portion 3 that are fixed to each other. The bottom end of the first lead portion 1 forms an electrical equipment connection end 11, which is used to fix with the electrical equipment 6.

[0035] Since the outlet hole 61 is located on the top of the electrical equipment 6, and the first lead wire part 1 is fixedly connected to the top of the electrical equipment 6, the bottom end of the first lead wire part 1 refers to the lower end of the first lead wire part 1 when the electrical equipment 6 is installed, that is, the end facing the electrical equipment 6. In the following text, "upper" refers to the side of the electrical equipment 6 facing the first lead wire part 1, and "lower" refers to the side of the first lead wire part 1 facing the electrical equipment 6.

[0036] The first lead section 1 is provided with a first lead cavity, the second lead section 3 is provided with a second lead cavity, and the connecting section 2 is provided with a connecting cavity. The connecting cavity connects the first lead cavity and the second lead cavity. The cable 5 of the electrical equipment 6 can pass through the outlet hole 61 and pass through the first lead section 1, the connecting section 2 and the second lead section 3 in sequence before being connected to the external equipment.

[0037] like Figure 1 and Figure 2 As shown, the connecting part 2 is located above the second lead part 3. After the cable 5 passes through the first lead part 1, it passes through the connecting part 2 located above, and then enters the second lead part 3 located below before connecting to an external device. The height of the part of the cable 5 located in the connecting part 2 is higher than the height of the part located in the second lead part 3.

[0038] like Figure 1 and Figure 2 As shown, the cable 5 has a first bending structure 51 formed between the second lead portion 3 and the connecting portion 2. The first bending structure 51 is an inverted U-shaped or V-shaped structure with the opening facing downwards. The highest point of the first bending structure 51 is located inside the connecting portion 2.

[0039] This design allows water falling onto the surface of cable 5 to flow along the outer wall of cable 5 to the second lead portion 3. Then, due to gravity, it will not continue to flow along the surface of cable 5 into the connecting portion 2. As a result, the water on the outer wall of cable 5 will accumulate in the second lead portion 3. Since the second lead portion 3 is located below the connecting portion 2, it prevents water in the second lead portion 3 from entering the connecting portion 2. This effectively prevents external water from entering the connecting portion 2 and the first lead portion 1, and further prevents external water from entering the electrical equipment 6 through the outlet hole 61. This ensures the normal operation of the electrical equipment 6 and avoids safety hazards caused by water ingress.

[0040] like Figure 5 As shown, a first wall portion 12 is formed on the side wall of the first lead portion 1 facing the second lead portion 3, and a second wall portion is formed on the side wall of the second lead portion 3 facing the first lead portion 1. The first wall portion 12 and the second wall portion are attached and fixed together. At the same time, the height of the second wall portion is not higher than the height of the first wall portion 12, which can prevent water in the second lead portion 3 from entering the first lead portion 1. Specifically, the height of the first wall portion 12 and the second wall portion can be the same, or the height of the first wall portion 12 can be higher than the height of the second wall portion.

[0041] Of course, in this embodiment, the first lead portion 1 and the second lead portion 3 can also be set as two completely independent structures, which are indirectly fixed only through the connecting portion 2, while the first wall portion 12 and the second wall portion are directly fixed. This can make the overall structure of the wiring mechanism more compact, reduce the length of the connecting portion 2 and effectively reduce the overall volume.

[0042] The connecting part 2 includes two interconnected parts: a first connecting part 21 and a second connecting part 22. The first connecting part 21 is fixedly connected to the first lead part 1, and the second connecting part 22 is fixedly connected to the top end of the second lead part 3. Of course, in this embodiment, the first connecting part 21 and the second connecting part 22 can also be set as an integral structure. However, setting the first connecting part 21 and the second connecting part 22 as separate structures and fixing them by welding, bolting, or other methods makes it easier to set the first connecting part 21 according to the structure of the first lead part 1 and the second connecting part 22 according to the structure of the second lead part 3, which provides good flexibility.

[0043] like Figure 1As shown, the cross-sectional structures of the connecting part 21 and the connecting part 22 are different. The structure of the connecting part 21 is set according to the structure of the first lead part 1. The cable 5 is not restricted when passing through the first lead part 1 and the connecting part 21, and can be a whole bundle. However, when it reaches the second lead part 3, the cable 5 is divided into two bundles and led to two opposite directions. Therefore, the cable 5 can be divided into two bundles starting from the connecting part 22. The angle between the two bundles of cable 5 gradually increases until it reaches the second lead part 3 and completely forms two bundles arranged in two opposite directions. The connecting part 22 forms a transition section for the cable 5 to be divided, avoiding the situation where the cable 5 is directly divided after reaching the second lead part 3, resulting in excessive bending angle and damage.

[0044] Specifically, the connecting part 21 and the first lead part 1 can be integrally formed, and the connecting part 22 and the second lead part 3 can also be integrally formed; no specific restrictions are imposed here.

[0045] When the connecting part 2 and the first lead part 1 are separate structures, such as Figure 4 and Figure 5 As shown, the connecting part 2 (specifically, the connecting part 21) is sleeved on the top of the first lead part 1 and fixed to the first lead part 1 by fasteners or welding. This prevents external rainwater from entering from the top of the first lead part 1, thus improving the waterproof effect. The second lead part 3 and the connecting part 2 can also be fixed by fasteners or welding.

[0046] The bottom of the connecting part 2 and the second lead part 3 are respectively provided with mutually compatible positioning structures, so that in the installed state, the positioning structure can ensure that the connecting cavity can communicate with the second lead cavity.

[0047] In this embodiment, there are no specific limitations on the positioning structure. For example, a positioning protrusion can be provided at the bottom of the connecting part 2. During installation, the positioning protrusion can be placed against the side wall of the second lead part 3. The positioning protrusion can be either a positioning plate 23 or a positioning post. Alternatively, the second lead part 3 can be provided with a positioning protrusion. During installation, the positioning protrusion of the second lead part 3 can be placed against the side wall of the connecting part 2.

[0048] The connecting part 2 is also equipped with a cable protection component, which can protect the cable 5 and prevent damage caused by friction between the first bending structure 51 and the edge of the first wall 12 or the second wall. Specifically, there are no restrictions on the structure of the cable protection component. For example, the cable protection component can be a guide groove fixed to the inner wall of the connecting part 2, or the cable protection component can be set as a flexible protective pad. The flexible protective pad is located at the edge of the first wall 12 or the second wall and can protect the cable 5 on the inside of the first bending structure 51.

[0049] Alternatively, within the connecting portion 2, the first bending structure 51 of the cable 5 can be configured to include a first segment, a connecting segment, and a second segment connected in sequence, wherein the first segment and the connecting segment form a first preset angle, and the second segment and the connecting segment form a second preset angle. The first preset angle and the second preset angle can be set according to the actual arrangement of each cavity.

[0050] The first segment, with its end furthest from the connecting segment, passes through the first lead section 1 and the outlet hole 61 into the electrical equipment 6, while the second segment, with its end furthest from the connecting segment, passes through the second lead section 3. This arrangement eliminates the need for direct bending of the cable 5, facilitating cable routing and reducing requirements for space and angle arrangement.

[0051] The first lead wire section 1 is also provided with a wire-blocking section 4 on the side facing the electrical equipment 6 connection section. The wire-blocking section 4 can form the lowest bending point of the cable. Specifically, after the cable 5 passes through the outlet hole 61, it will form a second bending structure 52 when passing through the wire-blocking section 4. The second bending structure 52 is U-shaped or V-shaped and the opening is upward. Then, after the cable 5 passes through the first lead wire section 1, the lowest bending point of the cable is located at the wire-blocking section 4, specifically at the lowest point of the second bending structure 52. Even if a small amount of water enters the first lead wire section 1 due to condensation or other reasons, this water may flow down along the outer wall of the cable 5 to the lowest point, and then the cable 5 bends upward and enters the outlet hole 61. This can prevent water from entering the outlet hole 61 along the cable 5, thereby preventing water from entering the electrical equipment 6, thus playing a waterproof role.

[0052] like Figure 3 and Figure 5 As shown, the wire-blocking part 4 has a U-shaped structure. The open end of the U-shaped structure forms a fixed end 41. The fixed end 41 can be fixed to the inner wall of the first lead wire part 1 or to the top of the electrical equipment 6. After the wire-blocking part 4 is fixed, it can form a wire-blocking hole. The cable 5 passes through the wire-blocking hole and forms a second bending structure 52 here.

[0053] Of course, in this embodiment, the wire-blocking part 4 can also be set as a stop bar or other structures. When it is set as a U-shaped structure, the fixed end 41 can form a closed wire-blocking hole after being fixed. The cable 5 is stable after passing through the wire-blocking hole, avoiding the situation of detaching from the wire-blocking part 4.

[0054] like Figures 3-5As shown, the first lead portion 1 also includes a lead segment 13 and a fixing segment 14 connected together. The lead segment 13 is located between the fixing segment 14 and the connecting portion 2. The fixing segment 14 has the aforementioned electrical equipment connection end 11. The wire-blocking portion 4 is located within the fixing segment 14. The cross-sections of the fixing segment 14 and the lead segment 13 can be different. The fixing segment 14 is used to fix to the top of the electrical equipment 6. The specific structure can be designed according to the top structure of the electrical equipment 6, such as... Figure 1 and Figure 2 As shown, when the electrical equipment 6 has two outlet holes 61 at its top, the two outlet holes 61 are spaced apart. The fixing section 14 must enclose both outlet holes 61 to ensure waterproof performance. The lead section 13 is only used to connect and fix the fixed section 14 and the connecting section (connecting section). Its structure is not restricted; for example, it can be set as a vertical cylindrical structure. Its cross-section is not limited by the top structure of the electrical equipment 6, and it can also reduce the structural requirements of the connecting part 2. The fixing section 14 can form a transition connection section between the electrical equipment 6 and the lead section 13.

[0055] Of course, in this embodiment, the first lead part 1 can also be set as an integral structure with an unchanged cross-section. However, when the first lead part 1 is set as two parts with different cross-sections, the first lead part 1 can meet the connection requirements with the top of the electrical equipment 6 while reducing the overall volume, reducing the installation space requirements, and effectively reducing costs.

[0056] In this embodiment, a waterproof protrusion 62 is also provided on the top of the electrical device 6 along the circumference of the outlet hole 61. The waterproof protrusion 62 can prevent water accumulated at the bottom of the first lead portion 1 from entering the electrical device 6 through the outlet hole 61. In order to ensure that the water in the first lead portion 1 can flow out smoothly, a drain hole can also be provided at the bottom of the first lead portion 1 (i.e., the side facing the electrical device connection end 11) to avoid excessive water accumulation inside.

[0057] In this embodiment, there are no restrictions on the specific structure of the first lead part 1, the connecting part 2 and the second lead part 3. The first lead part 1 and the connecting part 2 are both closed structures to prevent water from entering. If a cable tray is used, the mounting holes of the cable tray can be sealed. The second lead part 3 can be directly installed using a cable tray for easy installation and connection.
