Description

Technical Field

[0001] This utility model relates to the technical field of street light junction boxes, and in particular to an integrated waterproof junction box. Background Technology

[0002] Streetlight junction boxes are crucial components of streetlight electrical systems, used to connect and protect streetlight wiring and electrical equipment. They primarily consist of a box body, cover, terminals, and sealing materials. The box body and cover are mostly made of plastic or metal, connected by clips, screws, etc. Terminals are used to secure and connect wires, and include screw-type and plug-in types. Sealing materials, such as rubber sealing rings, are installed at the junction of the box body and cover, providing waterproofing and dustproofing.

[0003] Currently, existing street light junction boxes have the following technical problems: 1. Insufficient waterproofing: The waterproofing structure of some junction boxes is not reasonably designed, such as poor sealing of wire holes and gaps at the junction of the box body and cover. In harsh environments, water and dust can easily penetrate, affecting the stability and safety of electrical connections. 2. Inconvenient installation and use: To achieve multi-functional integration and better performance, some junction box structures are designed to be complex, requiring the use of more couplers and complex wiring, making installation and maintenance difficult in actual use. 3. High maintenance costs: Some street light junction boxes have high integration and complex structures. Once a fault occurs, repair is difficult, and some key components are difficult to replace individually after damage, resulting in increased manpower, repair time, and maintenance costs. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the technical problem to be solved by this utility model is to provide an integrated waterproof junction box, which solves the problems of insufficient waterproof performance, inconvenient installation and use, and high maintenance costs of existing street light junction boxes.

[0005] To solve the above-mentioned technical problems, this utility model provides an integrated waterproof junction box, comprising:

[0006] A housing assembly, comprising an upper housing and a lower housing, wherein the upper housing is sealed to the lower housing, and an accommodating space is formed between the upper housing and the lower housing;

[0007] Within the accommodating space, the lower housing has one or more electrical mounting positions for installing electrical components. The side walls on opposite sides of the lower housing have one or more wiring holes communicating with the accommodating space. The lower housing has one or more latching seats on opposite sides, each latching seat being equipped with an anti-detachment latch. The anti-detachment latch has a through-hole for the electrical connection wire of the external device to pass through the wiring hole and the through-hole to connect to the electrical component.

[0008] A sealing assembly, comprising a sealing element disposed between the upper housing and the lower housing, and one or more sealing rings configured to mate with one or more of the wire positioning holes.

[0009] As a more preferred embodiment, the electrical component and the electrical mounting position are respectively provided with mutually cooperating mounting holes and limiting members, one of which is located at the bottom of the electrical component and the other is located at the electrical mounting position. The cooperation between the mounting hole and the limiting member enables precise positioning of the electrical component, avoids offset or misalignment during manual installation, reduces adjustment time, and prevents loosening between the electrical component and the electrical mounting position due to long-term vibration or external force.

[0010] As a preferred approach, each of the aforementioned electrical mounting positions features an irregular boss structure; and / or, multiple sets of mating mounting holes and limiting components are arranged at equal intervals. The irregular boss structure combined with equally spaced mounting holes and limiting components allows for a more rational distribution of stress between the electrical components and the electrical mounting positions, preventing stress concentration at a single point or area, thereby reducing the likelihood of structural damage due to stress concentration and extending the equipment's service life. Furthermore, the equally spaced mounting holes and limiting components make the installation process of the electrical components more standardized and regulated; installers only need to align the mounting holes on the bottom of the electrical components with the limiting components according to fixed intervals and positions to quickly complete the installation without repeated adjustments, greatly saving installation time and improving overall assembly efficiency. Moreover, the equally spaced mounting holes and limiting components can evenly distribute the external forces acting on the electrical components. When the equipment is subjected to external forces such as vibration and impact, this uniform force distribution allows the electrical components to be more stably installed on the electrical mounting positions, reducing the risk of loosening and displacement, and ensuring the reliability of the equipment during long-term operation.

[0011] As a more preferred embodiment, each of the latching seats is provided with one or more latching slots, each latching slot being adapted to accommodate one anti-detachment latch. The latching slots allow the anti-detachment latch to be installed on the latching seat. When the anti-detachment latch is installed in the latching slot, it can limit the movement of the electrical connection wire clamped therein, restricting its movement in all directions. By providing multiple latching slots, different numbers or types of anti-detachment latches can be installed on the same latching seat to meet the fixing requirements of different electrical components.

[0012] As a more preferred embodiment, the anti-detachment buckle has protrusions on both sides, which cooperate with guide grooves on the side wall of the buckle seat to allow the anti-detachment buckle to be assembled onto the buckle seat. The protrusions on the anti-detachment buckle and the guide grooves on the buckle seat provide a precise installation position for the anti-detachment buckle, ensuring accurate installation. When the protrusions on both sides of the anti-detachment buckle are installed on the buckle seat along the guide grooves, they limit the anti-detachment buckle, avoiding installation difficulties or incomplete installation due to installation position deviations, thus improving assembly efficiency and accuracy.

[0013] As a preferred embodiment, the outer wall of the anti-detachment buckle and the inner wall of the buckle groove are respectively provided with concave and convex reinforcing ribs, and the through portion is a square groove. The anti-detachment buckle cooperates with each of the buckle grooves to secure one or more electrical connection wires. The concave and convex reinforcing ribs on the outer wall of the anti-detachment buckle and the inner wall of the buckle groove can further tighten the connection between the anti-detachment buckle and the buckle seat, restricting their movement in all directions. The through portion of the square groove can provide a larger contact area, allowing the buckle to apply pressure more evenly to the wires when multiple electrical connection wires need to be fixed, ensuring that each wire is firmly secured. This multi-point contact fixing method can effectively prevent the wires from loosening due to shaking, twisting, or external pulling during use, ensuring the stability of the electrical connection and avoiding problems such as poor contact, unstable signal transmission, or even electrical faults caused by loose wires. In addition, the square shape is more resistant to external forces than other shapes (such as circles). When the wiring structure is subjected to external forces such as compression or collision, the square groove can better disperse the stress, reduce damage to the electrical connection wires and clips, and ensure the overall stability and reliability of the wiring structure.

[0014] As a preferred embodiment, the central axis of the through-hole is aligned with the central axis of the mating snap-fit ​​groove. When the central axes of the through-hole and the snap-fit ​​groove coincide, the electrical connector can move along a straight path as it passes through the through-hole and snaps into the groove, avoiding additional resistance caused by bending or twisting during installation, thus making the installation process smoother and more efficient. Furthermore, the aligned central axes ensure that the electrical connector is evenly distributed within the through-hole and snap-fit ​​groove during clamping. When the anti-detachment snap-fit ​​clamps the wire, the pressure on the connector is evenly transmitted to all parts of the through-hole and snap-fit ​​groove, preventing damage to the connector or snap-fit ​​due to excessive localized force. Moreover, this even force distribution improves the fixing effect of the electrical connector, ensuring the stability and reliability of the connection between the connector and the electrical components.

[0015] As a preferred embodiment, the integrated waterproof junction box further includes: mating housing clips and housing clip positions, one of which is disposed on the upper housing and the other on the lower housing. The housing clips are inserted into the corresponding housing clip positions, ensuring a tight seal between the upper and lower housings. After the housing clips are inserted into the housing clip positions, they provide additional connection strength to the upper and lower housings. This mechanical connection effectively resists external forces, preventing deformation or damage to the housings due to impacts or compression during use, ensuring the durability of the seal and extending the service life of the junction box. Furthermore, when the housing clips are inserted into the housing clip positions, they exert moderate pressure on the sealing elements, fully filling the gaps between the housings to form a tight seal. This effectively prevents moisture, dust, and other external substances from entering the housing, significantly improving the waterproof and dustproof performance of the junction box.

[0016] As a preferred embodiment, the seal includes a foam seal to prevent water or dust from entering the containment space. During equipment use, the upper and lower housings may experience slight displacement or deformation due to factors such as temperature changes and vibration. The foam seal, with its excellent elasticity and flexibility, can adaptively adjust its shape to conform to the deformation of the housing, maintaining close contact with the housing surface at all times, thus achieving a dynamic seal. This dynamic sealing characteristic allows it to effectively prevent the intrusion of water or dust even in complex operating environments and conditions. Furthermore, when the equipment is subjected to external impacts (such as vibration or collisions), it can absorb and disperse these impacts, reducing the impact on the internal electrical components. This buffering and shock absorption effect protects the electrical components from damage, improves the stability and reliability of the equipment, and extends its service life. Moreover, the installation process of the foam seal is relatively simple, requiring no complex tools or processes. It can be directly installed with the housing components, reducing assembly time and labor costs.

[0017] As a more preferred embodiment, the one or more sealing rings include rubber sealing rings, each coaxially arranged with a corresponding wire positioning hole. Rubber has good elasticity; when the electrical connection wire passes through the wire positioning hole, the rubber sealing ring can be compressed and deformed. This deformation allows it to tightly conform to the inner wall of the electrical connection wire and the wire positioning hole, filling the tiny gaps between them. This effectively prevents external substances such as water and dust from entering the receiving space through the wire positioning hole, enhancing the sealing effect. Furthermore, when the sealing ring is coaxially arranged with the wire positioning hole, the center of the sealing ring coincides with the center of the wire positioning hole. When the electrical connection wire passes through the wire positioning hole, the sealing ring can evenly conform to the inner wall of the electrical connection wire and the wire positioning hole, forming a comprehensive seal. This avoids the problem of localized poor sealing due to eccentric sealing rings, improving the reliability and effectiveness of the seal.

[0018] As described above, the integrated waterproof junction box of this utility model has the following beneficial effects:

[0019] The lower housing has multiple electrical mounting positions, which can be arranged reasonably according to the size and shape of different electrical components, making it convenient for the installation and disassembly of electrical components. This modular design improves the scalability of the equipment and makes it easy to replace electrical components as needed in the future.

[0020] The assembly design of the anti-detachment buckle and buckle seat allows the electrical connection cable to move along a straight path as it passes through the through part and is snapped into the buckle slot. This avoids additional resistance to the electrical connection cable due to bending or twisting during installation, making the installation process smoother and more efficient, reducing operational difficulty and time costs, and improving wiring efficiency.

[0021] The overall structure is simple and the layout is reasonable. The installation and use process is relatively simple and does not require complicated tools and processes. The components can be directly installed and disassembled, which reduces the manpower time and labor costs for installation and maintenance.

[0022] In use, the integrated waterproof junction box of this utility model has an upper housing sealing cover that fits onto the lower housing, with a sealing element between them. This effectively prevents moisture from entering the containment space from the junction of the housings. The sealing element can adapt to minor unevenness on the housing surface, filling gaps and forming a tight waterproof barrier to prevent rainwater and moisture from corroding the internal electrical components, significantly improving the reliability of the equipment in humid environments or outdoor settings. The sealing rings for the wire positions fit together tightly against the electrical connection wires and the inner wall of the wire positions. When the electrical connection wires pass through the wire positions, the sealing rings are compressed and deformed, filling the gaps between them and preventing moisture from seeping in through the wire positions, further enhancing the overall waterproof capability and ensuring that the internal electrical system of the equipment is protected from water damage.

It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit the utility model.

[0059] like Figures 1 to 10 The figure shows a schematic diagram of an integrated waterproof junction box provided in this application, illustrating the structures of a two-hole integrated waterproof junction box, a four-hole integrated waterproof junction box, and a six-hole integrated waterproof junction box.

[0060] Specifically, the integrated waterproof junction box includes:

[0061] The housing assembly 1 includes an upper housing 11 and a lower housing 12, wherein the upper housing 11 is sealed to the lower housing 12, and an accommodating space is formed between the upper housing 11 and the lower housing 12.

[0062] Within the accommodating space, the lower housing 12 has one or more latching seats on opposite sides, each latching seat having an anti-detachment latch 4, and the anti-detachment latch 4 having a through portion 41; the side walls on opposite sides of the lower housing 12 have one or more wire position holes 121 communicating with the accommodating space, for the electrical connection wires of external devices to pass through; within the accommodating space, the lower housing 12 also has one or more electrical mounting positions 123 for installing electrical components 3 to connect with the electrical connection wires of the external devices;

[0063] The sealing assembly 2 includes a sealing element 21 disposed between the upper housing 11 and the lower housing 12, and one or more sealing rings 22 that are configured to cooperate with one or more wire position holes 121.

[0064] The housing assembly 1 includes an upper housing 11 and a lower housing 12, wherein the upper housing 11 is sealed to the lower housing 12, and an accommodating space is formed between the upper housing 11 and the lower housing 12.

[0065] In the accommodating space, the lower housing 12 is provided with one or more electrical mounting positions 123 for installing electrical components 3 respectively; the side walls on opposite sides of the lower housing 12 are provided with one or more wire positioning holes 121 communicating with the accommodating space; the lower housing 12 is provided with one or more latching seats 124 on opposite sides; each latching seat 124 is equipped with an anti-detachment latch 4, and the anti-detachment latch 4 has a through portion 41, so that the electrical connection wire of the external device passes through the wire positioning hole 121 and the through portion 41 and is electrically connected to the electrical component 3;

[0066] The sealing assembly 2 includes a sealing element 21 disposed between the upper housing 11 and the lower housing 12, and one or more sealing rings 22 that are configured to cooperate with one or more wire position holes 121.

[0067] To better illustrate the integrated waterproof junction box of this utility model, the following specific application will be used as an example: In use, the upper housing 11 seals and covers the lower housing 12, with a sealing element 21 positioned between them. This effectively prevents moisture from entering the containment space from the junction of the housings. The sealing element 21 can adapt to minor unevenness on the housing surface, filling gaps and forming a tight waterproof barrier to prevent rainwater and moisture from corroding the internal electrical components 3, significantly improving the reliability of the equipment in humid environments or outdoor settings. The sealing rings 22 of the wire position holes 121 fit together, tightly adhering to the electrical connection wires and the inner wall of the wire position holes 121. When the electrical connection wire passes through the wire position holes 121, the sealing rings 22 are compressed and deformed, filling the gap between them and preventing moisture from seeping in through the wire position holes 121, further enhancing the overall waterproof capability and ensuring that the internal electrical system of the equipment is protected from water damage.

[0068] The lower housing 12 has multiple electrical mounting positions 123 inside, which can be rationally arranged according to the size and shape of different electrical components 3, facilitating the installation and disassembly of the electrical components 3. This modular design improves the scalability of the equipment and makes it easy to replace the electrical components 3 as needed. The electrical components 3 are used to realize the connection between electrical wires and between electrical wires and electrical equipment, and can be of the types of screw type and crimp type. The screw type achieves the connection by tightening the screw to press the wire; the crimp type uses a crimping tool to crimp the terminal to the wire. The appropriate type is selected according to actual needs, and no specific limitation is made here.

[0069] The design of aligning the central axis of the through-hole 41 with the snap-fit ​​groove 1241 allows the electrical connection cable to move along a straight path as it passes through the through-hole 41 and snaps into the snap-fit ​​groove. This avoids additional resistance to the electrical connection cable due to bending or twisting during installation, making the installation process smoother and more efficient, reducing operational difficulty and time costs, and improving wiring efficiency. When the anti-detachment snap-fit ​​4 secures the wire, the pressure on the electrical connection cable is evenly distributed to all parts of the through-hole 41 and the snap-fit ​​groove 1241, preventing damage to the electrical connection cable or snap-fit ​​due to excessive localized force. This improves the fixing effect of the electrical connection cable and ensures the stability and reliability of the connection between the electrical connection cable and the electrical component 3.

[0070] The sealing component 2 designed in this invention includes a foamed seal and a rubber sealing ring. Due to the good elasticity and flexibility of the foamed seal, it can adaptively adjust its shape according to the deformation of the housing component 1, always maintaining close contact with the surface of the housing component 1, thereby achieving dynamic sealing. Furthermore, because rubber has good elastic properties, when the electrical connection wire passes through the wire positioning hole 121, the rubber sealing ring can be compressed and deformed. This deformation can tightly fit the electrical connection wire and the inner wall of the wire positioning hole 121, filling the tiny gaps between them, thereby effectively preventing water, dust, and other external substances from entering the receiving space through the wire positioning hole 121, enhancing the sealing effect.

[0071] In some embodiments of this utility model, such as Figure 4 and Figure 6 As shown, the electrical component 3 and the electrical mounting position 123 are respectively provided with mutually cooperating mounting holes 31 and limiting members 1231, one of which is located at the bottom of the electrical component 3 and the other is located on the electrical mounting position 123. The cooperation between the mounting hole 31 and the limiting member 1231 can achieve precise positioning of the electrical component 3, avoid offset or misalignment during manual installation, reduce adjustment time, and prevent loosening between the electrical component 3 and the electrical mounting position 123 due to long-term vibration or external force.

[0072] In some embodiments of this utility model, such as Figures 1 to 9 As shown, the one or more electrical mounting positions 123 have an irregular boss structure, and the mounting holes 31 and the limiting members 1231 are arranged at equal intervals. The irregular boss structure combined with the equally spaced mounting holes 31 and limiting members 1231 allows for a more reasonable distribution of stress between the electrical component 3 and the electrical mounting positions 123, preventing stress concentration at a single point or in a specific area. This reduces the likelihood of structural damage due to stress concentration and extends the service life of the equipment. Furthermore, the equally spaced mounting holes 31 and limiting members 1231 make the installation process of the electrical component 3 more standardized and regulated. Installers only need to align the mounting holes 31 at the bottom of the electrical component 3 with the limiting members 1231 according to fixed intervals and positions to quickly complete the installation without repeated adjustments, greatly saving installation time and improving overall assembly efficiency. Furthermore, the equally spaced mounting holes 31 and limiting members 1231 can evenly distribute the external forces on the electrical components 3. When the equipment is subjected to external forces such as vibration and impact, this uniform force distribution can make the electrical components 3 more stably installed on the electrical mounting position 123, reducing the risk of loosening and displacement, and ensuring the reliability of the equipment during long-term operation.

[0073] In some embodiments of this utility model, such as Figures 1 to 9As shown, each of the latching seats 124 is provided with one or more latching slots 1241, and each latching slot 1241 is adapted to accommodate one anti-detachment latch 4. The latching slots allow the anti-detachment latch 4 to be installed on the latching seat 124. When the anti-detachment latch 4 is installed in the latching slot 1241, the latching slot 1241 can limit the movement of the electrical connection wire that is locked therein, restricting its movement in all directions. By providing multiple latching slots 1241, different numbers or types of anti-detachment latches 4 can be installed on the same latching seat to meet the fixing requirements of different electrical components 3. For example, as Figure 7-10 As shown, for larger or irregularly shaped electrical components 3, multiple anti-detachment clips 4 can be used for fixing; while for smaller electrical components 3, fewer anti-detachment clips 4 can be used. This design improves the versatility and adaptability of the clip holder 124, reduces the number of clip holders of different specifications used, and lowers production costs.

[0074] In some embodiments of this utility model, such as Figures 4-5 As shown, the anti-detachment buckle 4 has protrusions 42 on both sides. The protrusions 42 cooperate with the guide grooves 1242 provided on the side wall of the buckle seat 124 to allow the anti-detachment buckle 4 to be assembled on the buckle seat. The protrusions 42 on the anti-detachment buckle 4 and the guide grooves 1242 on the buckle seat 124 provide a precise installation position for the anti-detachment buckle 4, enabling the anti-detachment buckle 4 to be accurately installed on the buckle seat 124. When the protrusions on both sides of the anti-detachment buckle 4 are installed on the buckle seat 124 along the guide grooves 1242, they can limit the anti-detachment buckle 4, avoiding installation difficulties or incomplete installation caused by installation position deviation, thus improving assembly efficiency and accuracy.

[0075] In some embodiments of this utility model, such as Figures 1 to 2 ,as well as Figures 4 to 8As shown, the outer wall of the anti-detachment buckle and the inner wall of the buckle groove are respectively provided with concave and convex reinforcing ribs 43, and the through part 41 is a square groove. The anti-detachment buckle 4 cooperates with each of the buckle grooves 1241 through the concave and convex reinforcing ribs 43 and the through part 41 to clamp one or more electrical connection wires. The concave and convex reinforcing ribs 43 provided on the outer wall of the anti-detachment buckle 4 and the inner wall of the buckle groove 1241 can further tighten the connection between the anti-detachment buckle 4 and the buckle seat 124, restricting its movement in all directions; the through part 41 of the square groove can provide a larger contact area. When multiple electrical connection wires need to be fixed, the buckle can apply pressure to the wires more evenly, so that each wire can be firmly clamped. This multi-point contact fixing method can effectively prevent the wires from loosening due to shaking, twisting or being pulled by external force during use, ensuring the stability of the electrical connection and avoiding problems such as poor contact, unstable signal transmission or even electrical failure caused by loose wires. Furthermore, square shapes are more resistant to external forces compared to other shapes (such as circles). When the junction box is subjected to external forces such as pressure or impact, the square groove can better disperse stress, reduce damage to electrical connection wires and clips, and ensure the overall stability and reliability of the wiring structure.

[0076] In some embodiments of this utility model, such as Figures 1 to 2 ,as well as Figures 4 to 8 As shown, the central axis of the through-hole 41 is aligned with the central axis of the corresponding latching groove 1241. When the central axes of the through-hole 41 and the latching groove 1241 coincide, the electrical connection wire can move along a straight path as it passes through the through-hole 41 and is inserted into the latching groove 1241. This avoids additional resistance caused by bending or twisting during installation, making the installation process smoother and more efficient. Furthermore, the coincident central axis design ensures that the electrical connection wire is evenly distributed within the through-hole 41 and the latching groove 1241 during clamping. When the anti-detachment latch 4 clamps the wire, the pressure on the electrical connection wire is evenly transmitted to all parts of the through-hole 41 and the latching groove 1241, preventing damage to the electrical connection wire or the latch due to excessive localized force. Moreover, this uniform force distribution improves the fixing effect of the electrical connection wire, ensuring the stability and reliability of the connection between the electrical connection wire and the electrical component 3.

[0077] In some embodiments of this utility model, such as Figures 1 to 9As shown, the integrated waterproof junction box further includes: a housing clip 111 and a housing clip position 122 that cooperate with each other, one of which is disposed on the upper housing 11 and the other on the lower housing 12. The housing clip 111 is inserted into the corresponding housing clip position 122, so that the upper housing 11 and the lower housing 12 are tightly sealed. After the housing clip 111 is inserted into the housing clip position 122, it can provide additional connection strength for the upper housing 11 and the lower housing 12. This mechanical connection method can effectively resist the action of external forces and prevent the housing from being deformed or damaged due to collisions, squeezing, etc. during use, ensuring the durability of the sealing effect and extending the service life of the junction box. In addition, when the housing clip 111 is inserted into the housing clip position 122, it will exert a moderate squeeze on the sealing element 21, so that it fully fills the gap between the housings, thereby forming a tight seal, effectively preventing moisture, dust and other external substances from entering the housing, and greatly improving the waterproof and dustproof performance of the junction box.

[0078] In some embodiments of this utility model, such as Figures 1 to 9 As shown, the housing latch 111 and the housing latch position 122 are symmetrically arranged relative to the upper housing 11 and the lower housing 12, respectively. The symmetrical arrangement of the housing latch 111 and the housing latch position 122 ensures that the upper housing 11 and the lower housing 12 are evenly stressed after being fastened. When subjected to external pressure, vibration, or impact, this uniform force distribution can disperse the force throughout the entire housing structure, avoiding local stress concentration that could lead to housing deformation or damage, and thus helping to extend the product's service life. For example, the integrated waterproof junction box is applied to a street light. The electrical connection wires of each component of the street light are passed through the wire positioning holes 121 provided on the lower housing 12. The electrical connection wires enter the receiving space formed by the upper housing 11 and the lower housing 12 through the wire positioning holes 121. Then, one end of the electrical connection wire is inserted into the electrical component 3 on the electrical mounting position. The anti-disengagement buckle 4 is installed on the buckle seat to fix and tighten the electrical connection wire. Then, one or more sealing rings 22 are installed on the wire positioning holes 121 respectively. Finally, the upper housing 11 is closed on the lower housing 12 to ensure the waterproofness and sealing of the entire waterproof junction box.

[0079] In some embodiments of this utility model, such as Figures 1 to 9As shown, the sealing element 21 includes a foamed seal, which prevents water or dust from entering the accommodating space. During equipment use, the upper housing 11 and lower housing 12 may experience slight displacement or deformation due to factors such as temperature changes and vibration. The foamed seal has good elasticity and flexibility, and can adaptively adjust its shape according to the deformation of the housing, always maintaining close contact with the housing surface, thereby achieving dynamic sealing. This dynamic sealing characteristic allows it to effectively prevent the intrusion of water or dust even in complex operating environments and conditions. In addition, when the equipment is subjected to external impact forces (such as vibration, collision, etc.), it can absorb and disperse these impact forces, reducing the impact on the electrical components 3 inside the housing assembly 1. This buffering and shock absorption effect can protect the electrical components 3 from damage, improve the stability and reliability of the equipment, and extend its service life. Furthermore, the installation process of the foamed seal is relatively simple and does not require complex tools and processes. It can be directly installed with the housing assembly 1, reducing assembly time and labor costs.

[0080] In some embodiments of this utility model, such as Figure 1 , Figures 4 to 9 As shown, the one or more sealing rings 22 include rubber sealing rings 22, which are coaxially arranged with the corresponding wire positioning holes 121. Rubber has good elasticity; when the electrical connection wire passes through the wire positioning hole 121, the rubber sealing ring can be compressed and deformed. This deformation allows it to tightly fit the electrical connection wire and the inner wall of the wire positioning hole 121, filling the tiny gaps between them. This effectively prevents external substances such as water and dust from entering the receiving space through the wire positioning hole 121, enhancing the sealing effect. Furthermore, when the sealing ring 22 is coaxially arranged with the wire positioning hole 121, the center of the sealing ring 22 coincides with the center of the wire positioning hole 121. When the electrical connection wire passes through the wire positioning hole 121, the sealing ring 22 can evenly fit against the electrical connection wire and the inner wall of the wire positioning hole 121, forming an all-around seal. This avoids the problem of localized poor sealing due to the eccentricity of the sealing ring 22, improving the reliability and effectiveness of the seal. For example, when there is one wire hole 121, a sealing ring 22 coaxial with the wire hole 121 is provided. When there are multiple wire holes 121, multiple sealing rings 22 corresponding to the wire holes 121 are provided coaxially. The specific number of sealing rings 22 is not limited.

[0081] In summary, the integrated waterproof junction box of this utility model has the following advantages:

[0082] 1. Junction box is easy to install and maintain:

[0083] The lower housing 12 has multiple electrical mounting positions 123 inside, which can be reasonably arranged according to the size and shape of the electrical components 3, making it convenient for installation and disassembly. The modular design improves the scalability of the equipment and facilitates the replacement of electrical components 3 in the future.

[0084] 2. Excellent connection stability and reliability:

[0085] The assembly design of the anti-loosening buckle and buckle seat allows the electrical connection cable to move in a straight line during installation, avoiding the additional resistance caused by bending and twisting, making the installation process smooth, reducing the difficulty and time cost of operation, and improving wiring efficiency; moreover, the electrical connection cable is subjected to uniform force, avoiding local damage, improving the fixing effect, and ensuring the stability and reliability of the connection between the electrical connection cable and the electrical component 3.

[0086] 3. Low maintenance costs:

[0087] The structure is simple and the layout is reasonable. The installation and use process is relatively simple and does not require complicated tools and processes. The components can be directly installed and disassembled, which reduces the manpower time and labor costs for installation and maintenance.

[0088] 4. Excellent waterproof performance:

[0089] A seal 21 is provided between the upper housing 11 and the lower housing 12 to adapt to minor unevenness and fill gaps, preventing moisture from entering from the joint of the outer housing assembly 1; the sealing ring 22 of the wire position hole 121 is matched, and the sealing ring 22 is deformed by compression to fill the gap, preventing moisture from seeping in from the wire position hole 121; the sealing assembly 2 adopts a foam seal and a rubber sealing ring. The foam seal can dynamically seal, and the rubber sealing ring fits tightly, which together enhances the overall waterproof capability, protects the internal electrical components 3, and improves the reliability of the equipment in humid or open-air environments.

[0090] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.
