Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation equipment connection technology, and in particular to a novel photovoltaic connector. Background Technology

[0002] In photovoltaic (PV) power generation systems, the reliability of connectors directly impacts the overall system's power generation efficiency and safety. Currently, PV connectors generally employ a combination of metal conductors and plastic housings. The core challenge lies in ensuring stable electrical contact performance of the conductors under harsh environments such as long-term vibration and temperature variations. As the power density of PV modules increases, the current that connectors need to carry becomes increasingly larger, placing ever more stringent demands on contact resistance and mechanical strength. In recent years, the mainstream industry trend has been to improve connector durability by refining contact structures and materials.

[0003] A search revealed Chinese publication number CN217882205U, which discloses a novel photovoltaic connector, including a pluggable positive connector and a negative connector. The positive connector includes a positive body, inside which are disposed a first anti-reverse ring, a positive copper component, and a first T-shaped sealing ring. The lower end of the first T-shaped sealing ring is fitted onto the upper end of the first anti-reverse ring, and the upper end of the positive copper component is inserted into the lower end of the first anti-reverse ring. A first turnbuckle is fitted onto the upper end of the first T-shaped sealing ring, and the lower end of the turnbuckle is connected to the upper end of the positive body. A first nut is disposed on the upper part of the positive body, and the first turnbuckle is disposed inside the first nut. In this connector design, the copper component and the anti-reverse ring are engaged at the locking ring of the copper component via claws at the locking point, achieving multi-point contact. This prevents the copper component from tilting during installation, significantly improving installation stability, reducing shaking, ensuring electrical performance stability, and enabling the connector to operate stably for extended periods.

[0004] The patent specification mentions that "both the upper ends of the positive and negative copper parts contain drum springs. Under the premise that the copper parts are installed without skewing, the positive and negative copper parts can be parallelly inserted, which can make the negative pin (copper part) fully and evenly contact the drum spring inside the positive pin (copper part), and also improve the electrical stability of the positive and negative copper parts." However, during the docking process, when the male terminal of the copper part is skewed, the female terminal is difficult to slide in smoothly, resulting in poor electrical docking stability during the docking process. In response to the above problems, a new type of photovoltaic connector is proposed. Utility Model Content

[0005] This utility model proposes a novel photovoltaic connector, which aims to improve the problem of poor electrical connection stability in some existing devices due to the misalignment of the male terminal during connection.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A novel photovoltaic connector includes a female connector body tube and a male connector body tube. A male terminal is slidably connected inside the female connector body tube, a guide mechanism is fixedly connected inside the female connector body tube, a female terminal is fixedly connected inside the male connector body tube, and an installation mechanism is fixedly connected outside the male connector body tube.

[0008] The guiding mechanism includes a round rod, the outside of which is fixedly connected to the inside of the female head body tube. A guide plate is slidably connected to the outside of the round rod, and the inside of the guide plate is slidably connected to the outside of the male terminal. A buffer spring is sleeved on the outside of the round rod, one end of which is fixedly connected to the inside of the female head body tube, and the other end of which is fixedly connected to the outside of the guide plate. A limit ring is fixedly connected to the outside of the round rod, and a fixing assembly is fixedly connected to the top of the female head body tube.

[0009] Through the above solution: the guiding mechanism inside the female connector body tube, through the cooperation of a round rod, guide plate, buffer spring and limiting ring, ensures that the male terminal can be stable and does not wobble during the sliding process, ensuring accurate docking of the male and female terminals and improving connection stability. The buffer spring can effectively absorb external impact, reduce the impact of vibration and other factors on the connection structure, and enhance the shock resistance of the connector. The fixing component further stabilizes the guiding mechanism and ensures reliable operation.

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

[0011] The installation mechanism includes a fixing plate, which is fixedly connected to the outside of the male head body tube. A limit rod is fixedly connected to the outside of the fixing plate. A fixing support is fixedly connected to the outside of the female head body tube. A limiting component is provided inside the fixing support. The limiting rod is slidably connected to the inside of the fixing support.

[0012] With the above solution, the male and female main tubes can be installed and fitted together through a sliding connection between the limiting rod and the fixed support. The limiting component can further limit the limiting rod, thereby achieving a stable relative position between the male and female main tubes, which facilitates the installation and positioning of the two and improves the convenience and stability of the installation.

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

[0014] The fixing component includes a fixing base, the bottom of which is fixedly connected to the inside of the female head body tube. A sliding plate is slidably connected inside the fixing base, and the outside of the male terminal is fixedly connected to the inside of the sliding plate.

[0015] With the above solution, the male terminal can slide within the fixed base via a sliding plate, facilitating the installation and position adjustment of the male terminal within the female connector's main tube. This also ensures the stability and reliability of the male terminal connection within the female connector's main tube, enhancing the practicality and adaptability of the connection structure.

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

[0017] The limiting component includes a limiting block, the outside of which is slidably connected to the inside of the fixed support. A return spring is fixedly connected inside the fixed support, and the other end of the return spring is fixedly connected to the outside of the limiting block. The outside of the limiting block is slidably connected to the inside of the limiting rod.

[0018] With the above solution, when the limiting rod slides within the fixed support, the limiting block can effectively limit the limiting rod, ensuring the stability of the connection. The return spring can reset after the limiting block slides, so that it can be used again next time, enhancing the repeatability and durability of the structure and improving the reliability and practicality of the entire installation mechanism.

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

[0020] The male connector body tube is externally threaded with a hexagonal nut, the male terminal is externally slidably connected to the inside of the female terminal, and the female terminal is externally slidably connected to the inside of the female connector body tube.

[0021] The above solution allows for easy tightening and disassembly of the male connector body tube via external threaded connections, enhancing connection stability and convenience. The female terminal slides inside the female connector body tube, ensuring smooth power and signal transmission between the male and female terminals.

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

[0023] A rubber ring is slidably connected inside the female connector body tube, a wire clamp is slidably connected outside the rubber ring, and the male terminal is slidably connected outside the rubber ring inside the rubber ring.

[0024] Through the above solution: the rubber ring acts as a seal and buffer, effectively preventing external dust and moisture from entering and protecting the internal connection structure; the wire clamp can stabilize the male terminal and prevent the male terminal from shaking and affecting the connection stability; the elasticity of the rubber ring provides appropriate tightening force, enhancing the reliability of the connection, so that the entire connection structure has the characteristics of sealing, stability and practicality.

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

[0026] The female head body tube is externally threaded with a loosening and tightening nut, and the external part of the clamp is slidably connected to the inside of the loosening and tightening nut.

[0027] The above method applies pressure to the clamp by tightening and loosening the screw. When the tightening nut is loosened and tightened, the internal sliding connection of the clamp will tighten, thus firmly fixing the male terminal and preventing it from loosening and falling off. When it is necessary to adjust and disassemble the cable, loosening the tightening nut will allow the clamp to return to its free sliding state.

[0028] As a further description of the above technical solution:

[0029] A sealing ring is fixedly connected to the outside of the male head body tube, and a sealing groove is provided inside the female head body tube. The sealing ring is slidably connected to the inside of the sealing groove.

[0030] With the above solution, when the male main tube is connected to the female main tube, the sealing ring can slide and fit tightly in the sealing groove, forming a good sealing structure, effectively preventing external dust, moisture, and gas impurities from entering the connection part, thereby ensuring the stability and reliability of the connection.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, a round rod provides a sliding path for the guide plate. When the male terminal is inserted, the guide plate keeps the male terminal from shaking, compresses the buffer spring, and limits the travel of the guide plate with a limiting ring, so as to achieve accurate insertion of the male terminal into the female terminal, effectively prevent the male terminal from shifting or shaking, ensure that the female terminal can be smoothly inserted, ensure stable electrical connection, and improve the reliability and stability of photovoltaic connector connection.

[0033] 2. In this utility model, the limiting rod is slid by the fixed plate. During the insertion of the fixed support, the limiting rod pushes the limiting block to overcome the elastic force of the reset spring. After alignment, the reset spring pushes the limiting block to lock the limiting rod, thereby completing the connection. This enables the male main tube and the female main tube to be quickly and accurately connected, ensuring a stable and reliable connection and improving the installation efficiency and safety of the photovoltaic connector.

Detailed Implementation

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0042] Reference Figures 1 to 2 This utility model provides an embodiment of a novel photovoltaic connector, comprising a female main tube 1 and a male main tube 4. The female main tube 1 is an important component of the photovoltaic connector, serving as a basic load-bearing structure and providing space for the installation of internal components. The male main tube 4 is used to fix a female terminal 5 inside. A male terminal 2 is slidably connected inside the female main tube 1. The male terminal 2 is one of the key components for achieving electrical connection and is made of a metal material with excellent conductivity. A guide mechanism 3 is fixedly connected inside the female main tube 1, which plays a guiding role during the connection process and ensures the stability of the electrical connection. The female terminal 5 is fixedly connected inside the male main tube 4. The female terminal 5 is also made of a metal material with excellent conductivity and corresponds to the male terminal 2. When the male terminal 2 is inserted, the two can make close contact to form a good electrical conduction path for achieving electrical connection. An installation mechanism 6 is fixedly connected to the outside of the male main tube 4, which is used to quickly connect the female main tube 1 and the male main tube 4.

[0043] Specifically, with the help of the mounting mechanism 6 on the outside of the male main tube 4, the female main tube 1 and the male main tube 4 can be quickly connected. During the connection process, the guide mechanism 3 inside the female main tube 1 plays a guiding role. Under the guidance of the guide mechanism 3, the male terminal 2 can be accurately inserted into the female terminal 5 inside the male main tube 4. After the male terminal 2 is inserted, the female terminal 5 and the male terminal 2 are in close contact, forming a good electrical conduction path and realizing electrical connection.

[0044] The guiding mechanism 3 includes a round rod 301, which provides a precise guiding path for the sliding of the guide plate 302. The round rod 301 is externally fixedly connected to the inside of the female head body tube 1, and the guide plate 302 is slidably connected to the outside of the round rod 301. The guide plate 302 is internally designed with a sliding groove that matches the shape of the male terminal 2, allowing it to fit tightly against the outside of the male terminal 2. During the connection process, the guide plate 302 plays a guiding and straightening role, preventing the male terminal 2 from shifting or shaking, and ensuring accurate docking with the female terminal 5. The inside of the guide plate 302 is slidably connected to the outside of the male terminal 2, and a buffer spring 30 is sleeved on the outside of the round rod 301. 3. When the male terminal 2 contacts the female terminal 5, the buffer spring 303 can absorb and buffer a certain impact force to prevent the two from being damaged due to rigid collision. One end of the buffer spring 303 is fixedly connected to the inside of the female head main tube 1, and the other end of the buffer spring 303 is fixedly connected to the outside of the guide plate 302. The outside of the round rod 301 is fixedly connected to the limiting ring 304, which limits the sliding stroke of the guide plate 302. The top of the female head main tube 1 is fixedly connected to the fixing component 305, which fixes the male terminal 2 to prevent the male terminal 2 from moving horizontally during the connection process.

[0045] Specifically, during the process of inserting the male terminal 2 into the female terminal 5 inside the male head body tube 4, the guide plate 302 slides on the precise guide path provided by the round rod 301. The sliding groove inside the guide plate 302, which is adapted to the shape of the male terminal 2, fits tightly against the male terminal 2, guiding and straightening the male terminal 2, preventing the male terminal 2 from shifting or shaking, and ensuring accurate docking with the female terminal 5. As the male terminal 2 gradually approaches the female terminal 5, the guide plate 302 compresses the buffer spring 303 sleeved on the outside of the round rod 301. The buffer spring 303 absorbs and buffers the impact force generated when the male terminal 2 contacts the female terminal 5. At the same time, the limiting ring 304 on the outside of the round rod 301 restricts the sliding stroke of the guide plate 302, ensuring that the entire guiding process is carried out within a reasonable range.

[0046] The fixing component 305 includes a fixing base 30501, which provides a mounting base and sliding track for the sliding plate 30502. The bottom of the fixing base 30501 is fixedly connected to the inside of the female head body tube 1. The sliding plate 30502 is slidably connected inside the fixing base 30501. The sliding plate 30502 is used to firmly fix the male terminal 2. The outside of the male terminal 2 is fixedly connected to the inside of the sliding plate 30502.

[0047] Specifically, the sliding plate 30502 can firmly fix the male terminal 2, and then the sliding plate 30502 and the male terminal 2 slide together into the fixing seat 30501. Since the fixing seat 30501 plays a horizontal limiting role on the sliding plate 30502, the sliding plate 30502 has a horizontal limiting effect on the male terminal 2, preventing the male terminal 2 from moving horizontally during the docking process.

[0048] Reference Figures 2 to 4 The mounting mechanism 6 includes a fixing plate 601, which serves as a support and connection, providing an installation position for the limiting rod 602. The fixing plate 601 is externally fixedly connected to the outside of the male head body tube 4. The limiting rod 602 is externally fixedly connected to the fixing plate 601. The limiting rod 602 plays a guiding and positioning role during the connector docking process, ensuring that the male head body tube 4 and the female head body tube 1 can be accurately docked. After docking, it limits the relative displacement between the two and improves the stability of the connection. The female head body tube 1 is externally fixedly connected to a fixing support 603. The fixing support 603 has a cavity and a groove inside that are adapted to the limiting rod 602 and the limiting component 604, providing space for the sliding of the limiting rod 602 and the installation of the limiting component 604. The fixing support 603 has a limiting component 604 inside, which is used to limit the position of the limiting rod 602 and ensure the stable connection of the connector. The limiting rod 602 is externally slidably connected inside the fixing support 603.

[0049] Specifically, during the docking process, the limiting rod 602 slides into the fixed support 603, and the limiting component 604 restricts the position of the limiting rod 602. After the male main tube 4 and the female main tube 1 are docked, the limiting rod 602 and the limiting component 604 work together to limit the relative displacement between the male main tube 4 and the female main tube 1, so that the connector maintains a stable connection, thereby ensuring the electrical connection of the photovoltaic system is stable and the current is transmitted normally.

[0050] The limiting component 604 includes a limiting block 60401. When the limiting rod 602 is inserted into the fixed support 603, the limiting block 60401 can be embedded in the corresponding groove of the limiting rod 602 to lock the limiting rod 602, preventing the connector from accidentally coming out during use and ensuring the reliability of the connection. The external part of the limiting block 60401 is slidably connected to the inside of the fixed support 603. The fixed support 603 is fixedly connected to the inside of the return spring 60402. When the male connector body tube 4 needs to be pulled out, the external force overcomes the elastic force of the return spring 60402, causing the limiting block 60401 to exit from the groove of the limiting rod 602. During the docking process, the return spring 60402 pushes the limiting block 60401 to automatically reset and embed into the corresponding groove of the limiting rod 602 to achieve the automatic locking function. The other end of the return spring 60402 is fixedly connected to the outside of the limiting block 60401, and the outside of the limiting block 60401 is slidably connected to the inside of the limiting rod 602.

[0051] Specifically, during the insertion of the limiting rod 602, it first contacts the limiting block 60401 inside the fixed support 603 and pushes the limiting block 60401 to overcome the elastic force of the return spring 60402, causing the limiting block 60401 to slide inside the fixed support 603. When the limiting rod 602 is inserted to a specific position and the corresponding groove aligns with the limiting block 60401, the return spring 60402 pushes the limiting block 60401 to automatically reset and embed into the groove of the limiting rod 602, thereby locking the limiting rod 602. At this time, the male head main tube 4 and the female head main tube 1 are connected. When it is necessary to disconnect and pull out the male head main tube 4, the operator applies external force to overcome the elastic force of the return spring 60402, causing the limiting block 60401 to exit from the groove of the limiting rod 602. The limiting rod 602 is no longer locked, and the male head main tube 4 can then be pulled out from the female head main tube 1.

[0052] Reference Figure 2 , Figure 4 and Figure 5The male connector body tube 4 is externally threaded with a hexagonal nut 7, which secures the male connector body tube 4 to the mounting plate. The male terminal 2 is externally slidably connected to the inside of the female terminal 5, and the female terminal 5 is externally slidably connected to the inside of the female connector body tube 1. A rubber ring 8 is slidably connected inside the female connector body tube 1. The rubber ring 8 primarily seals the gap between the cable and the female connector body tube 1, preventing external dust, moisture, and other impurities from entering the connector. A wire clip 9 is slidably connected to the outside of the rubber ring 8, further securing the male terminal 2 and preventing it from coming loose from the connector due to tension, vibration, or other external forces during use, thus ensuring the firmness and stability of the connection between the male terminal 2 and the connector. The male terminal 2 is externally slidably connected to the inside of the rubber ring 8. The female main body tube 1 is externally threaded with a loosening and tightening nut 10. By rotating the loosening and tightening nut 10, pressure can be applied to the wire clamp 9 to further tighten the male terminal 2. The wire clamp 9 is externally slidably connected to the inside of the loosening and tightening nut 10. The male main body tube 4 is externally fixedly connected with a sealing ring 11. When the male main body tube 4 and the female main body tube 1 are mated, the sealing ring 11 is compressed and tightly fitted in the sealing groove 12, forming an effective sealing barrier to prevent external dust and moisture from entering the connector. The female main body tube 1 is internally provided with a sealing groove 12. The sealing groove 12 can guide the sealing ring 11 to be accurately positioned. The external of the sealing ring 11 is externally slidably connected to the inside of the sealing groove 12.

[0053] Specifically, by rotating and loosening the tightening nut 10, pressure is applied to the wire clamp 9, which in turn squeezes the rubber ring 8, thereby further securing the rubber ring 8 to the male terminal 2, ensuring the firmness and stability of the connection between the male terminal 2 and the connector. When the male main body tube 4 and the female main body tube 1 are connected, the sealing ring 11 on the outside of the male main body tube 4 is compressed and tightly fitted into the sealing groove 12 inside the female main body tube 1, preventing external dust and moisture from entering the connector. The sealing groove 12 can guide the sealing ring 11 to be accurately positioned, ensuring the sealing effect.

[0054] Working principle: In use, first fix the male main tube 4 to the mounting plate with the hexagonal nut 7, rotate the loosening and tightening nut 10 on the outside of the female main tube 1 to apply pressure to the wire clamp 9, the wire clamp 9 squeezes the rubber ring 8, further tightening the male terminal 2, and then perform the docking operation. The limiting rod 602 on the fixing plate 601 on the outside of the male main tube 4 slides towards the fixing support 603 on the outside of the female main tube 1. During the insertion process, the limiting rod 602 pushes the limiting block 60401 in the fixing support 603 to overcome the elastic force of the return spring 60402 and slide. When the limiting rod 602 is inserted into a specific position, the groove of the limiting rod 602 aligns with the limiting block 60401, the return spring 60402 pushes the limiting block 60401 to embed into the groove and lock the limiting rod 602, thus completing the quick connection between the male main tube 4 and the female main tube 1.

[0055] Meanwhile, inside the female connector main tube 1, the sliding plate 30502 fixes the male terminal 2, preventing the male terminal 2 from moving horizontally during the docking process. The guide plate 302 slides under the guidance of the round rod 301, and the sliding groove inside the guide plate 302 fits the male terminal 2 to prevent the male terminal 2 from shifting. As the male terminal 2 approaches the female terminal 5, the guide plate 302 compresses the buffer spring 303 to buffer the impact force when the two come into contact. The limiting ring 304 limits the stroke of the guide plate 302. The male terminal 2 is accurately inserted into the female terminal 5 inside the male connector main tube 4 to achieve electrical connection. After the male connector main tube 4 docks with the female connector main tube 1, the sealing ring 11 outside the male connector main tube 4 is compressed inside the sealing groove 12 to form a seal and prevent external dust and moisture from entering the connector.

[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
