Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of photovoltaic components, and in particular relates to a photovoltaic connector waterproof component. Background Art
[0002] PV connectors play a crucial role in photovoltaic power generation systems. These specially designed electrical connectors typically connect two PV cables, ensuring a secure and reliable connection between PV panels and inverters or other critical components. PV connector design typically takes into account multiple factors, including high-temperature and UV resistance, as well as excellent electrical conductivity to withstand the harsh conditions of outdoor environments.
[0003] PV systems are typically installed outdoors, facing a variety of natural environmental challenges, including high temperatures, strong sunlight, rain, moisture, and windy sand. To withstand these conditions, PV connectors must exhibit excellent weather resistance. Many PV connectors utilize high-quality materials, such as polymers and metals, to ensure they withstand long-term environmental damage. Furthermore, these connectors must be designed for quick installation and removal, facilitating system maintenance and component replacement.
[0004] However, despite taking various environmental factors into account in the design of photovoltaic connectors, many existing connectors still lack sufficient waterproofing. This problem is particularly acute in rainy or humid environments. When moisture seeps into the connector, it can cause a range of serious problems, including electrical shorts, poor contact, and even equipment damage. This not only affects the system's power generation efficiency but also poses safety hazards and increases the risk of fire. Therefore, insufficient waterproofing has become a pressing challenge in photovoltaic connector design. Utility Model Content
[0005] In view of this, the utility model provides a photovoltaic connector waterproof component, which can solve the problem of insufficient waterproof level of the photovoltaic connector and further prevent water from entering the connection of the photovoltaic cable.
[0006] The utility model is achieved in this way:
[0007] The utility model provides a photovoltaic connector waterproof component, which includes a waterproof pipe sleeve, a sealing ring, and a support ring. The waterproof pipe sleeve is a cylindrical structure and is sleeved on the outside of the photovoltaic connector. Sealing rings are provided at both ends of the waterproof pipe sleeve. The sealing rings are used to seal the two ends of the waterproof pipe sleeve and are located at both ends of the photovoltaic connector and on the photovoltaic cable. A support ring is provided in the center of the two sealing rings inside the waterproof pipe sleeve. The support ring is used to support the waterproof pipe sleeve.
[0008] The technical effects of a photovoltaic connector waterproof component provided by the utility model are as follows: by setting a waterproof pipe sleeve, water can be prevented from entering the photovoltaic connection; by setting a sealing ring, water can be prevented from entering from both ends of the waterproof pipe sleeve; by setting a support ring, the middle of the waterproof pipe sleeve can be supported, which facilitates the movement of the sealing ring and the installation of the photovoltaic connector.
[0009] On the basis of the above technical solution, the photovoltaic connector waterproof assembly of the utility model can also be improved as follows:
[0010] Among them, the sealing ring is long and strip-shaped, including a fixed end and a free end. The fixed end is fixed to one end of the waterproof pipe sleeve, and a cylindrical channel is provided on the top. A nut is rotatably connected to the channel, and the free end is provided with a long strip opening with the same pitch as the nut.
[0011] Furthermore, the top of the nut faces the direction of the free end.
[0012] Furthermore, annular protrusions are provided at both ends of the inner side of the cylindrical channel on the fixed end, and recesses are provided at positions of the nut corresponding to the protrusions.
[0013] The beneficial effect of adopting the above-mentioned improvement scheme is that, by providing the protrusions and the recesses, the nut can only rotate within the fixed end.
[0014] Furthermore, the radius of the support ring is greater than the maximum radius of the photovoltaic connector.
[0015] Furthermore, the waterproof pipe sleeve is made of soft waterproof material.
[0016] Furthermore, the waterproof tube sleeve is made of silicone.
[0017] Furthermore, the sealing ring is made of silicone having a harderness greater than that of the waterproof tube sleeve.
[0018] Furthermore, recesses are provided at positions at both ends of the waterproof pipe sleeve corresponding to the sealing ring, and the width of the recess is equal to the width of the sealing ring.
[0019] Furthermore, the fixed end is fixedly connected to the waterproof pipe sleeve.
[0020] Compared with the prior art, the photovoltaic connector waterproof assembly provided by the present invention has the following beneficial effects:
[0021] Effective waterproofing: By providing waterproof sleeves and sealing rings, the components can effectively prevent moisture from entering the photovoltaic connector, thereby improving the waterproof performance of the connection and extending the service life of the equipment.
[0022] Enhanced sealing: The design of the sealing ring ensures the sealing of both ends of the waterproof sleeve, further preventing water from seeping from the connection and protecting the internal circuit from the influence of humid environment.
[0023] Support stability: The design of the support ring not only enhances the structural stability of the waterproof pipe sleeve, but also helps the sealing ring maintain proper position during installation to avoid sealing failure.
[0024] Easy to install and maintain: The long strip design of the sealing ring and the rotating connection of the nut can easily adjust the sealing effect, improving the convenience of installation and subsequent maintenance.
[0025] Enhanced fixation: By setting protrusions and recesses, the nut can only rotate within the fixed end. This design effectively prevents the component from loosening during use and improves the security of the connection.
[0026] Reasonable material selection: The waterproof pipe sleeve uses soft waterproof material (such as silicone), which has good flexibility and adaptability, while the sealing ring uses a harder material to ensure the durability and reliability of the sealing effect.
[0027] Strong adaptability: The radius of the support ring is larger than the maximum radius of the photovoltaic connector, ensuring that the component can be effectively supported in various installation situations and improving overall adaptability.
[0028] Simple design: The overall design is simple and clear, which is convenient for large-scale production and application, and can also reduce production costs.
[0029] In summary, through a series of design innovations and material selections, the photovoltaic connector waterproof component not only improves the waterproof performance of the photovoltaic connector, but also enhances its installation convenience and reliability, providing important guarantees for the long-term stable operation of the photovoltaic power generation system.
