Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a photovoltaic connector drum spring. Background Technology

[0002] The drum spring of a photovoltaic connector is a key component. It is made of metal material with good elasticity and conductivity. In a photovoltaic system, the drum spring plays the role of electrical connection and mechanical fastening. When the photovoltaic connector is inserted into place, the drum spring will generate elastic deformation, tightly holding the pin or socket, ensuring a reliable electrical connection between the two, reducing contact resistance and reducing power loss.

[0003] A search revealed Chinese patent publication number CN218940070U, which discloses a photovoltaic connector drum spring, relating to the field of photovoltaic technology. The drum spring includes a drum spring plate, the drum spring plate forming a drum spring body with its ends joined together. The outer sidewalls of the drum spring body are uniformly provided with stamping holes, and ribs are formed between adjacent stamping holes. The length direction of the ribs is parallel to the length direction of the drum spring body, and the ribs decrease inwards from both ends of the drum spring body to form a concave arc. One end of the drum spring plate is integrally provided with an insertion block for forming the stamping holes, and the other end of the drum spring plate is provided with an adjustment hole for the stamping holes. The application provides a recessed area for inserting a block, which reduces the cost of producing drum springs of different specifications. However, the ribs in this application are formed by stamping holes in the drum spring plate, and their number is fixed during the stamping process. Since the number of ribs depends on the preset layout of the stamping holes, it is impossible to flexibly increase or decrease the ribs according to the actual contact pressure and conductivity requirements of the photovoltaic connector. When it is necessary to adapt to photovoltaic connectors of different specifications, if the existing number of ribs cannot meet the contact stability requirements, the drum spring plate mold must be redesigned, resulting in poor production flexibility and difficulty in efficiently responding to diverse market demands. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a photovoltaic connector drum spring, which aims to improve the problem in the prior art where the protrusions are formed by the stamping holes of the drum spring plate, and their number is fixed during the stamping of the drum spring plate, making it impossible to flexibly add or remove protrusions according to the actual contact pressure and conductivity requirements of the photovoltaic connector.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a photovoltaic connector drum spring, comprising two metal rings, wherein multiple circular protrusions are fixedly connected at equal intervals on the outer adjacent sides of the two metal rings, multiple metal ribs are provided between the two metal rings, and connecting pieces are fixedly connected to the upper and lower ends of the multiple metal ribs, and circular slots are provided on the outer sides of the multiple connecting pieces, and the multiple circular slots are respectively sleeved on the outside of the multiple circular protrusions, and a rib locking mechanism is provided on the outside of the two metal rings.

[0006] The above technical solution uses circular protrusions as installation points. Metal ribs are fixed by fitting into the circular protrusions through the circular slots of the connecting pieces. The number of metal ribs can be increased or decreased as needed, and disassembly can be performed by applying reverse force. This ensures structural stability under different numbers of ribs, achieving flexible adaptation and stable connection. The number of metal ribs can be adjusted as needed to adapt to various specifications of photovoltaic connectors. The uniform slot and protrusion structure ensures installation stability, and the elasticity of the metal ribs achieves reliable electrical contact, meeting the needs of diverse application scenarios.

[0007] As a further description of the above technical solution:

[0008] The top-mounted rib locking mechanism includes a locking ring. The bottom of the locking ring has multiple equidistant gate-shaped grooves. The outer side of the metal ring has multiple threaded holes one at equal intervals. The outer side of the locking ring has multiple threaded holes two at equal intervals. The interior of each of the multiple threaded holes one and threaded holes two is threaded with a locking bolt. The interior of the locking ring is provided with a limit component.

[0009] The above technical solution achieves the following: the locking ring's slot initially limits the metal rib connecting piece and the circular protrusion; the locking bolt passes through threaded hole two and threaded hole one and is tightened, causing the locking ring to press down and fix the metal rib; the limiting component prevents its horizontal displacement; and loosening the bolt releases the lock. This achieves the effect of stable locking and flexible adjustment of the metal rib. The combination of multiple structures ensures that the metal rib does not shake during use, and disassembly and adjustment are convenient. This improves the stability and practicality of the photovoltaic connector drum spring structure and meets the installation and maintenance needs under different working conditions.

[0010] As a further description of the above technical solution:

[0011] The limiting component includes multiple slide bars, which are fixedly connected at equal intervals to the top inner side of the locking ring. Multiple slide grooves are equally spaced on the top outer side of the metal ring.

[0012] The above technical solution involves a sliding bar fixed to the top of the inner side of the locking ring, which cooperates with a groove opened on the top of the outer side of the metal ring to provide guidance for the installation of the locking ring. During installation, the sliding bar is embedded in the groove and slides, ensuring that the locking ring is accurately aligned and improving the overall structural stability.

[0013] As a further description of the above technical solution:

[0014] Each of the locking bolts has an internal hexagonal groove on its outer side, and the outer side of each of the internal hexagonal grooves is chamfered.

[0015] The above technical solution allows for easy insertion of hexagonal socket tools on the outer side of the locking bolt, enabling bolt tightening and loosening. The chamfered design prevents scratches when inserting tools, reduces wear, and improves operational smoothness.

[0016] As a further description of the above technical solution:

[0017] Both metal rings have rubber heads fixedly connected at equal intervals inside, and the interiors of the rubber heads are respectively attached to the ends of multiple internal hexagonal slots.

[0018] The above technical solution involves two rubber heads fixed inside the metal rings, which fit into the end of the hexagonal groove inside the locking bolt. This serves as a buffer and increases the friction between the locking bolt and the metal rings, preventing the locking bolt from loosening during use.

[0019] As a further description of the above technical solution:

[0020] All of the aforementioned metal ribs adopt an outward arc design, and all of the aforementioned metal ribs adopt a flat design.

[0021] The above technical solution features an outward-curving metal rib design that allows it to better adapt to the contact surface during photovoltaic connector mating, increasing the contact area and improving electrical connection stability. The flat design reduces space occupation, facilitates flexible arrangement between metal rings, and makes it easier to adjust the quantity. It also reduces its own weight and optimizes the overall performance of the drum spring.

[0022] As a further description of the above technical solution:

[0023] The inner sides of the plurality of metal ribs are fixedly connected with reinforcing ribs, and the plurality of reinforcing ribs adopt the same arc-shaped design as the metal ribs.

[0024] The above technical solution involves a reinforcing rib fixed to the inner side of the metal rib, which adopts the same arc design as the metal rib. The reinforcing rib enhances the structural strength of the metal rib and disperses stress when the metal rib is subjected to external pressure or tension, preventing deformation or breakage.

[0025] As a further description of the above technical solution:

[0026] The internal dimensions of the multiple gate-shaped slots are respectively matched with the external dimensions of the multiple circular protrusions, and the interior of the multiple gate-shaped slots adopts an inner arc design.

[0027] The above technical solution involves matching the internal dimensions of the door-shaped groove at the bottom of the locking ring with the circular protrusion. The inner arc design fits the metal rib connecting piece and the shape of the circular protrusion. During installation, the two are fitted together to form a preliminary limit, achieving a firm lock and facilitating disassembly and adjustment of the number of metal ribs.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, a circular protrusion is used as the installation point. The metal rib is fixed by being inserted into the circular protrusion through the circular groove of the connecting piece. The number of metal ribs can be increased or decreased as needed, and the structure can be disassembled by applying reverse force. This ensures structural stability under different numbers of ribs, achieving the effect of flexible adaptation and stable connection. The number of metal ribs can be adjusted as needed to adapt to various specifications of photovoltaic connectors. The uniform groove and protrusion structure ensures installation stability. The elasticity of the metal ribs achieves reliable electrical contact, meeting the needs of diverse application scenarios.

[0030] 2. In this utility model, the locking ring's gate-shaped groove initially limits the metal rib connecting piece and the circular protrusion. The locking bolt passes through threaded hole two and threaded hole one and is tightened, causing the locking ring to press down and fix the metal rib. The limiting component prevents its horizontal displacement. Loosening the bolt can release the lock, achieving the effect of stable locking and flexible adjustment of the metal rib. The combination of multiple structures ensures that the metal rib does not shake during use, and disassembly and adjustment are convenient. It improves the stability and practicality of the photovoltaic connector drum spring structure and meets the installation and maintenance needs under different working conditions.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 5 An embodiment of this utility model is provided: a photovoltaic connector drum spring, including two metal rings 1, with multiple circular protrusions 3 fixedly connected at equal intervals on the outer adjacent sides of the two metal rings 1, multiple metal ribs 4 provided between the two metal rings 1, with connecting pieces 5 fixedly connected to the upper and lower ends of the multiple metal ribs 4, and circular slots 6 opened on the outer side of the multiple connecting pieces 5, with the multiple circular slots 6 respectively sleeved on the outside of the multiple circular protrusions 3, and a rib locking mechanism 2 provided on the outside of the two metal rings 1;

[0040] Specifically, two metal rings 1 serve as the basic frame components of the drum spring, providing support and fixation for the entire structure. Multiple circular protrusions 3, equidistantly fixed to adjacent sides of the outer edges of the metal rings 1, constitute the mounting carrier for the metal ribs 4. The circular protrusions 3 are evenly distributed along the circumference of the metal rings 1, forming corresponding mounting points on opposite sides of the two metal rings 1. The metal ribs 4 are the components that enable electrical connection and elastic contact for the photovoltaic connector drum spring. Multiple metal ribs 4 are positioned between the two metal rings 1, and each metal rib 4 has a connecting piece 5 fixedly connected to its upper and lower ends. The connecting piece 5 acts as the connection medium between the metal rib 4 and the metal ring 1. A circular groove 6 is formed on the outer side of the connecting piece 5, its inner diameter matching the outer diameter of the circular protrusion 3, allowing the circular groove 6 to fit tightly onto the outside of the circular protrusion 3. During assembly, the number of metal ribs 4 can be freely selected according to the actual usage requirements of the photovoltaic connector. Since the circular protrusions 3 are equidistantly distributed on the metal rings 1, and each circular protrusion 3 can serve as... As independent installation points, some or all of the circular protrusions 3 can be selected for assembly. Align the circular slots 6 of the connecting pieces 5 at the upper and lower ends of the metal rib 4 with the corresponding circular protrusions 3, and press or insert them to fit the circular slots 6 into the circular protrusions 3, thus completing the installation and fixation of a single metal rib 4. When it is necessary to adjust the number of metal ribs 4, some metal ribs 4 can be directly disassembled, and the circular slots 6 of the connecting pieces 5 can be detached from the circular protrusions 3 by applying reverse force. Since the number and distribution of the circular protrusions 3 on the metal ring 1 are fixed, and each circular protrusion 3 and the connecting piece 5 of the metal rib 4 adopt the same structure, the structural stability after installation can be guaranteed no matter how the number of metal ribs 4 changes. After multiple metal ribs 4 are installed, their own elastic characteristics and distribution can achieve stable electrical contact and pressure transmission during the photovoltaic connector docking process. At the same time, by flexibly adjusting the number of metal ribs 4, different specifications of photovoltaic connectors can be adapted to meet the needs of diverse application scenarios.

[0041] Reference Figure 1 , Figure 3 and Figure 4 The top protruding rib locking mechanism 2 includes a locking ring 201. The bottom of the locking ring 201 is provided with multiple gate-shaped grooves 202 at equal intervals. The outer side of the metal ring 1 is provided with multiple threaded holes 203 at equal intervals. The outer side of the locking ring 201 is provided with multiple threaded holes 204 at equal intervals. The interior of the multiple threaded holes 203 and the threaded holes 204 are all threaded with locking bolts 205. The locking ring 201 is provided with a limit component inside.

[0042] Specifically, the locking ring 201 serves as the main frame of the rib locking mechanism 2. Multiple equidistant portal grooves 202 at its bottom correspond to the connecting piece 5 and circular protrusion 3 of the metal rib 4. When the metal rib 4 is installed between two metal rings 1, the locking ring 201 covers the metal ring 1, and the portal grooves 202 fit precisely on the outside of the connecting piece 5 and circular protrusion 3 of the metal rib 4, forming a preliminary limit. The equidistant threaded holes 203 on the outside of the metal ring 1 and 204 on the outside of the locking ring 201 provide installation channels for the locking bolts 205. The threaded holes 203 and 204 correspond one-to-one in the vertical direction. After the locking ring 201 is placed above the metal ring 1, the locking bolts 205 are passed through the threaded holes 204 and 203 in sequence, and tightened by screwing the threads to secure the locking ring. Locking ring 201 is securely connected to metal ring 1. As locking bolt 205 is tightened, the distance between locking ring 201 and metal ring 1 gradually decreases. The groove wall of the portal groove 202 applies pressure to the connecting piece 5 of metal rib 4, thereby firmly fixing metal rib 4 to the circular protrusion 3 of metal ring 1. The limiting component inside locking ring 201 further enhances the limiting effect on metal rib 4. The limiting component restricts the horizontal displacement of metal rib 4, preventing it from shaking or shifting during use. When disassembling or adjusting metal rib 4, simply loosen locking bolt 205 and remove locking ring 201 from metal ring 1 to release the lock on metal rib 4. This facilitates the adjustment or replacement of the number of metal ribs 4, achieving reliable locking and convenient operation of metal rib 4, and ensuring the stability and practicality of photovoltaic connector drum spring.

[0043] Reference Figure 1 , Figure 3 and Figure 4 The limiting component includes multiple slide bars 206, which are equidistantly fixed to the inner top of the locking ring 201. Multiple grooves 207 are equidistantly provided on the outer top of the metal ring 1. Multiple locking bolts 205 have internal hexagonal slots 208 on their outer sides, and the external surfaces of these slots are chamfered. Rubber heads 209 are equidistantly fixed to the interiors of both metal rings 1, and the interiors of these rubber heads 209 are respectively fitted to the ends of the internal hexagonal slots 208. Multiple metal ribs 4 have an outward arc design and a flat design. Reinforcing ribs 7 are fixedly connected to the inner sides of each metal rib 4, and these reinforcing ribs 7 have the same arc design as the metal ribs 4. The internal dimensions of multiple portal grooves 202 match the external dimensions of multiple circular protrusions 3, and the interiors of the portal grooves 202 have an inward arc design.

[0044] Specifically, the sliding strip 206 fixed to the top inner side of the locking ring 201 cooperates with the sliding groove 207 opened on the top outer side of the metal ring 1 to provide guidance for the installation of the locking ring 201. During installation, the sliding strip 206 slides into the sliding groove 207 to ensure precise alignment of the locking ring 201 and improve the overall structural stability. The internal hexagonal groove 208 on the outer side of the locking bolt 205 facilitates the insertion of an internal hexagonal tool to tighten and loosen the bolt. The chamfered design avoids scratching when inserting the tool, reduces wear, and improves the smoothness of operation. The rubber heads 209 fixed inside the two metal rings 1 fit against the ends of the internal hexagonal grooves 208 of the locking bolt 205, which serves as a buffer and increases the friction between the locking bolt 205 and the metal ring 1 to prevent the locking bolt 205 from loosening during use. The outward arc of the metal rib 4 The design allows it to better adapt to the contact surface when mating with photovoltaic connectors, increasing the contact area and improving the stability of the electrical connection. The flat design reduces the space occupied, facilitates flexible arrangement between metal rings 1, and makes it easier to adjust the number. At the same time, it reduces its own weight and optimizes the overall performance of the drum spring. The reinforcing rib 7 fixed inside the metal rib 4 adopts the same arc design as the metal rib 4. The reinforcing rib 7 enhances the structural strength of the metal rib 4 and disperses stress when the metal rib 4 is subjected to external pressure or pulling, preventing deformation or breakage. The internal dimensions of the door-shaped groove 202 at the bottom of the locking ring 201 match the circular protrusion 3. The inner arc design fits the shape of the metal rib 4 connecting piece 5 and the circular protrusion 3. During installation, it fits the two to form a preliminary limit, achieves a firm lock, and facilitates disassembly and adjustment of the number of metal ribs 4.

[0045] Working Principle: Multiple circular protrusions 3, equidistantly fixed on adjacent sides of the outer side of the metal ring 1, constitute the mounting carrier for the metal ribs 4. The circular protrusions 3 are evenly distributed along the circumference of the metal ring 1, forming corresponding mounting points on opposite sides of the two metal rings 1. The metal ribs 4 are components that enable electrical connection and elastic contact for the photovoltaic connector's spring. Multiple metal ribs 4 are positioned between the two metal rings 1, and each metal rib 4 has a connecting piece 5 fixedly connected to its upper and lower ends. The connecting piece 5 serves as the connection medium between the metal rib 4 and the metal ring 1. The circular groove 6 on the outer side of the connecting piece 5 has an inner diameter that matches the outer diameter of the circular protrusion 3, allowing the circular groove 6 to fit tightly onto the outside of the circular protrusion 3. During assembly, the mounting of the metal ribs 4 can be freely selected according to the actual usage requirements of the photovoltaic connector. The number of circular protrusions 3 is fixed because they are evenly distributed on the metal ring 1, and each circular protrusion 3 can be used as an independent installation point. Some or all of the circular protrusions 3 can be selected for assembly. The circular slots 6 of the connecting pieces 5 at the upper and lower ends of the metal rib 4 are aligned with the corresponding circular protrusions 3. By pressing or embedding, the circular slots 6 are fitted into the circular protrusions 3, and the installation and fixing of a single metal rib 4 can be completed. When it is necessary to adjust the number of metal ribs 4, some metal ribs 4 can be directly removed. By applying reverse force, the circular slots 6 of the connecting pieces 5 can be disengaged from the circular protrusions 3. Since the number and distribution of the circular protrusions 3 on the metal ring 1 are fixed, and each circular protrusion 3 and the connecting piece 5 of the metal rib 4 adopt the same structure, the structural stability after installation can be guaranteed no matter how the number of metal ribs 4 changes.

[0046] Furthermore, the multiple portal grooves 202 equidistantly opened at the bottom of the locking ring 201 correspond to the positions of the connecting piece 5 and the circular protrusion 3 of the metal rib 4. When the metal rib 4 is installed between the two metal rings 1, the locking ring 201 covers the metal ring 1, and the portal grooves 202 fit precisely on the outside of the connecting piece 5 and the circular protrusion 3 of the metal rib 4, forming a preliminary limit. The threaded holes 1 203 equidistantly opened on the outside of the metal ring 1 and the threaded holes 204 equidistantly opened on the outside of the locking ring 201 provide installation channels for the locking bolt 205. The threaded holes 1 203 and 204 correspond one-to-one in the vertical direction. When the locking ring 201 is placed on top of the metal ring 1, the locking bolt 205 is used to pass through the threaded holes 204 and 1 203 in sequence, and then... The locking ring 201 is securely connected to the metal ring 1 by tightening the locking bolt 205. As the locking bolt 205 is tightened, the distance between the locking ring 201 and the metal ring 1 gradually decreases. The groove wall of the portal groove 202 applies pressure to the connecting piece 5 of the metal rib 4, thereby firmly fixing the metal rib 4 to the circular protrusion 3 of the metal ring 1. The limiting component set inside the locking ring 201 further enhances the limiting effect on the metal rib 4. The limiting component restricts the horizontal displacement of the metal rib 4, preventing it from shaking or shifting during use. When disassembling or adjusting the metal rib 4, simply loosen the locking bolt 205 and remove the locking ring 201 from the metal ring 1 to release the locking of the metal rib 4, making it convenient to adjust or replace the number of metal ribs 4.
