[0028] The utility model embodiment is further described below in combination with the drawings.
[0029] Refer to Figure 1 , Figure 1 It is the side view of the rotating buckle photovoltaic module connector provided in an embodiment of the utility model. The connector contains male end plug-in assembly 110 and female end plug-in assembly 120 matched with male end plug-in assembly 110. Among them, male end plug-in assembly 110 includes first shell 111, and a circle or multiple circles of spiral grooves can be arranged on first shell 111;Female end plug-in assembly 120 includes second shell 121, and the flange is arranged on second shell 121. Further, buckle recess 112 is arranged on spiral groove, and buckle convex position 122 is arranged on the flange. When male end plug-in assembly 110 and female end plug-in assembly 120 are tightly connected, the flange can slide along the spiral groove and be tightly engaged with it, to ensure the stability of connection. At the same time, buckle recess 112 and buckle convex position 122 can also be mutually buckled to realize locking, further enhancing the reliability of connection.
[0030] In some embodiments of the utility model, in actual operation, if two photovoltaic modules need to be connected, male end plug-in assembly 110 and female end plug-in assembly 120 can be correctly butt-jointed first, and then any end is slowly rotated until a slight click sound is heard, which indicates that buckle recess 112 and buckle convex position 122 have been buckled, that is, male end plug-in assembly 110 and female end plug-in assembly 120 have been firmly locked. If the connection of the two is to be released, it can be easily separated by reversing the rotation by the same angle. The whole connection process greatly shortens the connection and disassembly time between photovoltaic modules, which not only can significantly improve the work efficiency of construction personnel, but also can significantly reduce the risk of misoperation.
[0031] It should be noted that the design of spiral groove and flange can customize products of different specifications according to diversified actual use environment, to meet various application requirements, and the utility model does not set any limitation thereto.
[0032] In some embodiments of this invention, to effectively prevent short circuit risks caused by dust and moisture intrusion, sealing strips can be added at key locations where the spiral groove and flange interlock, i.e., sealing strips are installed at the joint gap between them to ensure a tight seal. Furthermore, to comprehensively improve sealing performance and dust and water resistance, O-rings or other high-performance sealing gaskets can be additionally installed around the connection interface between the male connector 110 and the female connector 120. These sealing gaskets not only effectively isolate the external environment but also allow for flexible color customization to meet specific visual or marking requirements based on the actual application scenario.
[0033] In some embodiments of this utility model, the number of snap-fit recesses 112 and snap-fit protrusions 122 can be set to one or more as needed. For example, if two snap-fit recesses 112 are configured on the spiral groove, then correspondingly, two snap-fit protrusions 122 should also be symmetrically arranged on the flange to ensure that they can be accurately engaged, thereby achieving a stable and tight connection between the male end plug assembly 110 and the female end plug assembly 120. It should be noted that this utility model does not impose any fixed limitation on the specific number of snap-fit recesses 112 and snap-fit protrusions 122.
[0034] In some embodiments of this utility model, when the spiral groove is equipped with two snap-fit recesses 112, these two snap-fit recesses 112 can be symmetrically distributed on both sides of the spiral groove. Correspondingly, two symmetrical snap-fit protrusions 122 can also be provided on the flange to match the layout of the snap-fit recesses 112.
[0035] Furthermore, such as Figures 2-4 As shown, each snap-fit recess 112 can be composed of a positioning groove 210 and a locking groove 220 connected to the positioning groove 210. During the connection process between the male end plug assembly 110 and the female end plug assembly 120, the snap-fit protrusion 122 first achieves initial engagement with the positioning groove 210 in the snap-fit recess 112, and then, through a rotational action, the snap-fit protrusion 122 smoothly enters and locks into the locking groove 220, thereby completing the engagement process between the snap-fit recess 112 and the snap-fit protrusion 122.
[0036] In some embodiments of this utility model, the snap-fit protrusion 122 includes a first connecting surface 230, a second connecting surface 240, and a third connecting surface 250 connected in sequence. During the initial engagement between the snap-fit protrusion 122 and the positioning groove 210, the inner surface of the positioning groove 210 can contact the first connecting surface 230 and the second connecting surface 240 and generate abutment force, thereby achieving the initial positioning function. As the connection action deepens, when the snap-fit protrusion 122 further slides into the locking groove 220, the inner surface of the locking groove 220 will come into close contact with the second connecting surface 240 and the third connecting surface 250 and generate abutment force, thereby ensuring that the snap-fit protrusion 122 can be securely locked in the locking groove 220. This design not only enhances the stability of the snap-fit connection, but also improves the reliability and durability of the connection.
[0037] It should be noted that this utility model does not limit the specific structural form of the snap-fit recess 112 and the snap-fit protrusion 122, and can be flexibly designed and adjusted according to actual needs. Specifically, both the combination of the positioning groove 210 and the locking groove 220 of the snap-fit recess 112, and the configuration of the first connecting surface 230, the second connecting surface 240, and the third connecting surface 250 of the snap-fit protrusion 122, can be customized according to specific application scenarios and performance requirements. This design flexibility ensures that the connector can adapt to a variety of different connection needs, providing users with a wider range of choices.
[0038] In some embodiments of this invention, to significantly improve the stability of the connection and effectively prevent misalignment caused by improper control of a single rotation amplitude, an inner adjustment mechanism can be introduced on top of the outer rotation mechanism (i.e., the tight engagement of the spiral groove and the flange). Specifically, the male end plug-in assembly 110 has a built-in first adjustment mechanism, while the female end plug-in assembly 120 is equipped with a precisely matched second adjustment mechanism. These two mechanisms work together to finely adjust the relative position between the male and female end plug-in assemblies 120, ensuring that the snap-fit recess 112 and snap-fit protrusion 122 can achieve accurate engagement. In practical applications, the design forms of the first and second adjustment mechanisms are diverse. Among them, fine-tuning gears or threaded mechanisms are two efficient and practical implementation methods. Taking the fine-tuning gear as an example, it adopts a fine tooth pitch design, which allows for extremely subtle and controllable displacement adjustment with each rotation, thereby achieving precise control of the connection position. The threaded mechanism, on the other hand, uses rotational action to push or pull a part of the plug-in assembly to achieve fine-tuning. This design not only enhances the stability of the connection, but also allows users to make more precise adjustments by rotating or moving the outer layer, further improving the reliability and convenience of the connection.
[0039] Further, in order to increase the flexibility and adaptability of the adjustment mechanism, elastic elements (such as springs) can also be introduced into the adjustment mechanism. These elements can provide certain buffer and feedback force during fine tuning, making the adjustment process smoother and more controllable.
[0040] It should be noted that the above is only an example of a possible adjustment mechanism structure, and does not represent the specific design in the actual product. In actual application, the specific structure of the adjustment mechanism may vary due to product requirements, material selection, manufacturing cost, etc., and the present utility model does not limit this.
[0041] In some embodiments of the present utility model, in order to ensure that the connection position after fine tuning can maintain high stability and avoid any accidental displacement, a locking mechanism can also be provided. This mechanism can firmly fix the position of the adjustment mechanism (such as the fine tuning gear) after the adjustment operation is completed through rotation, sliding or pressing, etc., so as to ensure the long-term stability of the connection state. In specific implementation, the first locking mechanism can be configured inside the male plug-in assembly 110, which is specifically used to stabilize the position of the first adjustment mechanism; correspondingly, the second locking mechanism can be set inside the female plug-in assembly 120 to lock the second adjustment mechanism. It should be noted that the specific implementation form of the locking mechanism can be flexibly designed according to the actual application requirements. For example, an elastic element (such as a spring) can be used to provide the necessary locking force to ensure that the adjustment mechanism will not easily move after fine tuning due to external force. A rotatable locking ring can also be designed to firmly fix the position of the adjustment mechanism by rotating the ring, further improving the stability of the connection.
[0042] In some embodiments of the present utility model, in view of the possible extreme weather conditions, in order to ensure the continuous and stable operation of the photovoltaic module connector in the harsh environment of wind and sand, rain and snow, a protective cover can also be added outside the photovoltaic module connector. This protective cover can be made of durable and excellent protective materials, so as to effectively resist the invasion of wind and sand and the penetration of rain and snow, thereby protecting the key components inside the connector from damage. It should be noted that the protective cover can closely fit the shape of the connector to ensure good sealing and stability in extreme environments. At the same time, the installation and removal process of the protective cover is simple and fast, which is convenient for users to maintain or replace when necessary.
[0043] In some embodiments of the utility model, in the design of photovoltaic module connector, the material selection of spiral groove and flange is directly related to the durability, weight and electrical performance of the connector. Therefore, the preparation material of spiral groove can preferentially select stainless steel or aluminum alloy. These two materials have excellent wear resistance and corrosion resistance, and can maintain the stability of the structure and the reliability of the connection in long-term use. Specifically, stainless steel is particularly suitable for environments with high humidity or corrosive substances due to its excellent corrosion resistance; while aluminum alloy is an ideal choice for lightweight and high-performance connectors due to its lightweight, high strength, good thermal conductivity and corrosion resistance. In addition, the preparation material of the flange can preferentially select plastic or nylon. These two materials not only effectively reduce the overall weight of the connector, facilitating installation and transportation, but also have good insulation performance, reducing the risk of static interference, thereby ensuring the safety and stability of the connector in electrical connection. Plastic materials are popular due to their good processing performance and low cost; nylon materials have high strength, wear resistance, oil resistance, and chemical corrosion resistance, and can maintain excellent performance in various harsh environments. In addition, as an important part of the connector, the sealing gasket can be preferably made of silicone products. Silicone has unique physical and chemical properties, which can maintain good elasticity and sealing performance within a wide temperature range (-40°C to +200°C), effectively preventing moisture, dust and other impurities from entering the connector, and ensuring stable operation of the connector in extreme environments.
[0044] It is worth noting that all metal surfaces in the connector should be coated with an appropriate amount of lubricating oil before the first assembly to prevent rust. To ensure that the metal parts can maintain good working condition for a long time after the first assembly and effectively prevent rust problems, a layer of appropriate lubricating oil can be uniformly applied to all metal contact surfaces before the assembly operation officially begins. This step not only significantly reduces the frictional resistance between metal parts, facilitating the smooth progress of the assembly process, but more importantly, it forms a protective film on the metal surface, effectively isolating moisture and oxygen in the air, thereby greatly reducing the risk of rust. In addition, when selecting lubricating oil, it should ensure that it has good lubricating performance and rust prevention performance, and the compatibility with the contacted metal material should also be guaranteed to avoid chemical reaction causing damage to the metal surface. In addition, the amount of lubricating oil should be moderate, ensuring comprehensive coverage while avoiding excessive pollution or affecting the electrical performance of the connector during assembly. Through this pretreatment measure, not only the assembly efficiency and connection quality of the photovoltaic module connector can be improved, but also its service life can be significantly prolonged, providing more durable and reliable service.
[0045] The above is a specific description of the preferred embodiment of the present application, but the present application is not limited to the above-mentioned embodiments, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the present application, and these equivalent modifications or replacements are all included in the scope defined by the claims of the present application.
