Description

Technical Field

[0001] This invention relates to the field of photovoltaic interface technology, and more specifically to a photovoltaic interface for an MPPT converter. Background Technology

[0002] Photovoltaic interfaces are connectors used to connect photovoltaic panels to each other, or between panels and inverters or other electronic devices. These connectors play a crucial role in photovoltaic systems, ensuring efficient power transmission and stable system operation.

[0003] Existing photovoltaic (PV) connectors are susceptible to vibration, shock, and mechanical impact, which can lead to cable loosening and increased resistance. Even in large-scale PV power plants, a small increase in resistance can result in significant energy loss. Unstable cable connections can cause resistive heating, leading to localized overheating of the cable. If this heating raises the temperature to a level that could cause the insulation or wires to spontaneously combust, it can cause a fire. Loose connectors increase resistance when current flows, resulting in energy loss; electrical energy is converted into heat, affecting system efficiency. As resistance increases, some electrical energy is lost as heat, leading to system energy loss and impacting equipment performance.

[0004] Loose connectors can cause current fluctuations, affecting the normal current transmission and operation of equipment. When current flows through a loose connector, the voltage drop can affect the power stability of the receiving device. Loose connectors can create localized high resistance, leading to localized overheating. Overheating can damage wires, cables, or connectors, and even cause a fire. Furthermore, loose connectors can generate arcing and sparks, increasing fire and safety risks, and may also cause equipment interruptions, failures, or malfunctions, thus affecting the reliability and lifespan of the equipment. The stability of voltage, current, and signals in the system can be affected by loose connectors, thus impacting the normal operation of the system. In addition, loose connectors may expose wires and cables, increasing the risk of electric shock and other safety hazards. Therefore, connector problems can sometimes be difficult to detect, especially inside complex electronic equipment, and must be given high priority.

[0005] In view of the above, in order to overcome the above technical problems, the present invention designs a photovoltaic interface for an MPPT converter, which solves the above technical problems. Summary of the Invention

[0006] The technical problem this invention aims to solve is that loose photovoltaic connectors can lead to localized high resistance, which in turn can cause localized overheating. This overheating can raise the temperature to a level sufficient to cause spontaneous combustion of insulation materials or wires, potentially leading to a fire and increasing fire and safety risks. Furthermore, loose connectors can also cause equipment interruptions, breakdowns, or malfunctions, thereby affecting the reliability and lifespan of the equipment.

[0007] To address the above problems, the present invention provides the following technical solution:

[0008] This invention provides a photovoltaic interface for an MPPT converter, including a photovoltaic connector body and a connector housing, as well as a photovoltaic connector and a stabilizing cylinder. The photovoltaic connector, through the horizontal displacement of the rotating cylinder, compresses the stabilizing block, pressing it towards the center to firmly fix the cable. Simultaneously, the stabilizing block drives a transmission component, causing the transmission component to apply downward force, restricting the movement of the stabilizing cylinder. Furthermore, the stabilizing cylinder effectively restricts and stabilizes the movement of the photovoltaic connector, making the optical cable less susceptible to external shaking and vibration, thereby maintaining connection stability.

[0009] Photovoltaic connectors secure cables by using a stabilizing block to ensure a strong and stable connection between the cable and the connector. This helps prevent the cable from loosening due to external factors or vibration, ensuring the stability of power transmission. The stabilizing block gradually presses towards the center during rotation, ensuring a tight connection between the block and the cable. As the stabilizing block presses towards the center, it generates a downward force through the transmission components, which acts as a limit on the stabilizing cylinder. This design ensures moderate pressing force, preventing damage to the interface or related components due to excessive force. The introduction of the stabilizing cylinder makes the photovoltaic connector more stable and reliable during installation and use. The presence of the stabilizing cylinder reduces the instability of the connector under the influence of external environment or vibration, thereby improving the performance of the photovoltaic system. Through the design of the rotating cylinder and stabilizing block of the photovoltaic connector, the connector shell can achieve a certain degree of locking, effectively preventing the photovoltaic connector from loosening during use.

[0010] The photovoltaic connector includes a rotating cylinder, a rotating hole, a stabilizing pad, a stabilizing block, a pressing block, a fixed disc, a fixing groove, a fixing sleeve, and a transmission assembly. The rotating cylinder is rotatably mounted at both ends of the connector housing. The rotating cylinder has a convex cross-section and a rotating hole at its center. The right end of the rotating hole is shaped like an inverted frustum. A stabilizing block is slidably mounted inside the inverted frustum at the right end of the rotating hole. A stabilizing pad is slidably mounted on the rotating cylinder. A pressing block is fixedly mounted on the right end of the stabilizing block. A fixing disc is fixedly mounted inside the pressing block. A fixing groove with a U-shape is provided on the fixing disc. A fixing sleeve is fixedly mounted around the pressing block. A transmission assembly is fixedly mounted on the pressing block.

[0011] The rotating cylinder with a convex cross-section and the inverted frustum-shaped rotating hole allow the stabilizer block to slide and position within specific directions and angles, ensuring highly precise installation and thus guaranteeing the stability of the photovoltaic connector during connection. The rotating cylinder and the inverted frustum-shaped rotating hole allow the stabilizer block to secure the optical cable through compression. This compression operation is controllable, and the degree of compression can be adjusted as needed to ensure a tight connection between the stabilizer block and the cable. The stabilizer block itself slides within the inverted frustum-shaped rotating hole, maintaining a stable trajectory during compression. This helps prevent instability or displacement of the stabilizer block, ensuring the reliability of the cable connection. The compression design of the stabilizer block allows the cable to be stably clamped, reducing the risk of excessive stress and minimizing cable wear or damage. Through the compression action of the stabilizer block, the connection between the cable and the connector becomes more robust.

[0012] The presence of the fixing disc and fixing groove ensures precise positioning of the extrusion block during extrusion. The "U"-shaped fixing groove ensures correct alignment of the stabilizing block during extrusion, thus guaranteeing the stability and reliability of the connection. The design of the fixing disc evenly distributes the extrusion force throughout the stabilizing block, avoiding excessive localized stress and protecting it from damage. The presence of the fixing sleeve ensures the stability of the fixing disc, preventing unnecessary displacement or wobbling during installation. This helps ensure that the stabilizing block always maintains the correct extrusion position. The combination of the fixing sleeve and fixing disc improves the durability of the entire joint system and reduces the possibility of loosening or damage during long-term use. The U-shaped design of the fixing groove provides a suitable position for the stabilizing block, ensuring correct alignment during extrusion and preventing displacement or shifting.

[0013] The stabilizer has a right-angled trapezoidal cross-section and an arc-shaped inclined surface. The stabilizer cooperates with the fan-shaped extrusion block to convert the extrusion force of the stabilizer into the vertical displacement force of the transmission component. Due to the extrusion action of the stabilizer, the connection between the cable and the connector becomes stronger.

[0014] The right-angled trapezoidal cross-section and curved bevel design of the stabilizer block ensure a more uniform distribution of extrusion pressure throughout the block. This avoids excessive stress points and improves the stabilizer block's durability. Furthermore, the mating of the stabilizer block's curved bevel with the fan-shaped extrusion block ensures effective contact between them. This design is highly adaptable, effectively transferring extrusion pressure even in cases of imperfect alignment. The mating design between the extrusion block and the stabilizer block allows the force applied by the extrusion block to be converted into vertical displacement of the transmission components, thereby improving transmission efficiency. This helps ensure the limiting protection of the stabilizer cylinder. The curved bevel of the stabilizer block and the inverted frustum shape at the right end of the rotating hole help avoid impacts or vibrations caused by sudden applied forces, improving operational stability. The uniform distribution of extrusion pressure and improved transmission efficiency help reduce unnecessary stress on the stabilizer block and related components, thereby improving the overall system's durability and reliability.

[0015] A limiting block is installed at the bottom of the fixed sleeve. The shape of the limiting block is consistent with the shape of the fixed groove, and the thickness of the limiting block is greater than the thickness of the fixed disc, which makes the photovoltaic connector easy to install and at the same time plays a stabilizing role for the photovoltaic connector.

[0016] The presence of the limiting block ensures the correct positioning of the photovoltaic connector during installation. By matching the shape of the limiting block to the fixing groove, the limiting block can easily slide into the groove, making the installation process more convenient and faster. The shape of the limiting block conforms to the fixing groove, meaning that once inserted, it locks the connector in a specific position, preventing movement or displacement during use. The limiting block provides additional stability to the bottom of the photovoltaic connector, helping to ensure its stability during use and preventing instability due to external factors or vibrations, thus avoiding loosening of the optical cable due to shaking.

[0017] The stabilizing pad consists of two pads, each with a radially textured outer surface. The radially textured outer surface provides the stabilizing pad with anti-slip properties, helping to maintain stability when in contact with the component, thereby preventing loosening and slippage at the contact point. The inner surface has a beveled toothed surface, which can better align the position between the stabilizing pad and the stabilizing block, ensuring that the stabilizing block can be correctly positioned during the extrusion process, thereby guaranteeing the stability of the connection.

[0018] The combination of radially textured and beveled surfaces allows the stabilizing pad to better adapt to different surfaces and components during connection and installation. The radially textured surface provides a wider contact area, while the beveled surface offers greater flexibility in adaptability. The radially textured surface provides better anti-slip properties for the stabilizing pad, helping to maintain stability when in contact with components and preventing loosening and slippage. Simultaneously, the radially textured surface also provides better force transmission efficiency during compression, ensuring that the compressive force is effectively transferred to the stabilizing block and other related components. Furthermore, the radially textured surface reduces stress concentration during contact, extending the service life of the stabilizing pad and other components. The beveled surface provides better alignment between the stabilizing pad and the stabilizing block, ensuring that the stabilizing block is correctly positioned during compression, thereby guaranteeing connection stability.

[0019] The transmission assembly includes a transmission rod, a connecting rod, a rotating hole, a stabilizing rod, a fixed cylinder, a compression cylinder, a fixed block, and a compression spring. One end of the transmission rod is fixedly mounted on the compression block, and the other end of the transmission rod is rotatably mounted on the connecting rod. The transmission rod has a rotating hole. The stabilizing rod is fixedly mounted at the center of the connecting rod, and the central axis of the stabilizing rod is perpendicular to the central axis of the optical cable. The other end of the connecting rod is rotatably mounted on the fixed cylinder. The compression cylinder is fixedly mounted at the lower end of the fixed cylinder. The compression block is installed inside the compression cylinder, and the compression spring is engaged above the fixed block.

[0020] Through the collaboration of components such as the transmission rod, connecting rod, and stabilizing rod, the power transmission of the stabilizing block can be transferred to the extrusion cylinder of the connector, thus helping to ensure the stability and reliability of the extrusion process. The design of the connecting rod and stabilizing rod ensures good alignment between the extrusion cylinder and the stabilizing block, with the central axis of the stabilizing rod perpendicular to the central axis of the optical cable, ensuring the correct positioning of the stabilizing block. The stabilizing block is installed in a groove inside the extrusion cylinder, and a compression spring is placed above the stabilizing block. This design ensures that the stabilizing block is adequately protected during the extrusion process, preventing excessive stress from adversely affecting the stabilizing block and reducing friction on the stabilizing block during rotation, thereby reducing frictional loss. Through the design of the connecting rod and transmission rod, the power transmission can be effectively transmitted at the center position of the connecting rod, improving transmission efficiency and reducing energy loss.

[0021] The front end of the transmission rod is fan-shaped, which can provide a wider contact area during the extrusion process, thereby enabling the power to be transmitted to the fixed block in the extrusion cylinder.

[0022] The fan-shaped front end of the drive rod provides a wider contact area during extrusion, effectively transmitting power to the stabilizing block and other related components, helping to ensure the stability and reliability of the transmission. The fan-shaped front end allows for even distribution of transmitted force among the stabilizing block and other contact parts, reducing stress concentration and improving the durability and lifespan of related components. The wider contact area of ​​the fan-shaped front end helps disperse transmitted force, reducing impact forces on related components and minimizing the risk of component damage due to excessive impact. The fan-shaped drive rod can better fit the groove shape of the stabilizing block, ensuring that the extrusion force is evenly transmitted to the stabilizing block for a more stable extrusion effect. Furthermore, the fan-shaped front end of the drive rod can achieve a larger contact area at a smaller angle, making operation easier and requiring less force, thus reducing the difficulty of use for the user.

[0023] The cross-sectional shape of the fixing block is "+", which can adapt to the extrusion force in different directions. The lower cross-sectional shape of the "+" shaped fixing block is a right trapezoid. The right trapezoidal bottom shape of the fixing block can better match the stabilizing cylinder, ensuring that the fixing block is correctly aligned during connection and extrusion.

[0024] The cross-sectional shape of the "+" shaped stabilizer block provides enhanced stability. This shape strengthens the stabilizer block's anti-rotation properties in different directions, ensuring a secure connection. The right-angled trapezoidal base better matches the stabilizing cylinder, ensuring proper alignment during connection and compression. The stabilizer block's structural design allows the compression force to be evenly distributed throughout the compression cylinder, guaranteeing connection stability. Furthermore, the right-angled trapezoidal design helps reduce stress concentration, improving the stabilizer block's durability and lifespan. This "+" shaped stabilizer block's cross-sectional shape can accommodate compression forces in different directions, while the right-angled trapezoidal design reduces unnecessary rotation or movement, preventing loosening due to instability. Additionally, the right-angled trapezoidal base design also serves as a protective measure, reducing the risk of damage from improper compression. The right-angled trapezoidal shape at the stabilizer block's base makes it easier to slide into the corresponding groove during installation, allowing for quick and accurate engagement with the stabilizing cylinder for a secure fixation.

[0025] The stabilizing cylinder includes a protective cylinder, a rotating cylinder, a limiting cylinder, and a limiting groove. The protective cylinder is fixedly installed on the photovoltaic connector. The rotating cylinder is installed on the left side of the protective cylinder, and the limiting cylinder is installed on the left side of the rotating cylinder. A limiting groove is formed on the limiting cylinder. The limiting groove is an isosceles trapezoid. The limiting groove and the right-angled trapezoid at the lower end of the fixing block cooperate with each other, so that the fixing block limits and stabilizes the stabilizing cylinder.

[0026] By incorporating a protective cylinder, rotating cylinder, limiting cylinder, and limiting groove, the stabilizing cylinder effectively restricts and stabilizes the stabilizing block, ensuring the stability of the joint position during extrusion. This helps maintain the accuracy and robustness of the connection. The shape of the limiting groove coordinates with the right-angled trapezoid at the bottom of the stabilizing block, constraining it within the stabilizing cylinder and preventing shaking or vibration from affecting it, thus ensuring the continuity of the connection. The stabilizing cylinder design prevents loosening due to shaking or other reasons, ensuring the robustness of the connection and preventing the cable from coming loose midway. The limiting effect of the stabilizing cylinder improves the overall reliability of the joint. Enhanced stability and vibration suppression help extend the service life of the stabilizing cylinder and the joint, reducing the frequency of maintenance and repair. The stabilizing cylinder design improves operational safety, reducing the risks of accidental operation or malfunction. By improving stability and reliability, the risks caused by accidental operation or malfunction are reduced. The stabilizing cylinder design effectively prevents cable breakage due to loosening or vibration during use, protecting the integrity of the optical cable and the reliability of signal transmission.

[0027] The beneficial effects of this invention are as follows:

[0028] 1. This invention designs a photovoltaic connector. The photovoltaic connector, through the design of elements such as a rotating cylinder, a stabilizing block, and a fixed disc, ensures that the stabilizing block can slide and be positioned within a specific direction and angle, thereby achieving precise stability during the connection process and preventing cable loosening or misalignment. The connector employs a compression block, a fixed disc, and a fixing groove to achieve controllable compression of the cable, ensuring a tight connection between the cable and the connector, thus significantly improving the reliability of the connection.

[0029] 2. This invention utilizes a carefully designed stabilizing block. The meticulous design of the stabilizing block's cross-section and curved surface ensures that the compressive force is evenly distributed throughout the block, thereby reducing localized stress and significantly improving its durability. The curved surface and the inverted frustum-shaped rotating hole on the stabilizing block enable control of the movement trajectory within specific directions and angles, effectively preventing instability or deviation and ensuring the reliability of the cable connection. The shape design of the stabilizing block's cross-section ensures that the compressive force is evenly distributed, reducing localized stress concentration and further enhancing its durability.

[0030] 3. This invention utilizes a stabilizing cylinder design. Through the ingenious design of a protective cylinder, a rotating cylinder, a limiting cylinder, and a limiting groove, the stabilizing cylinder effectively restricts and stabilizes the movement of the fixing block, ensuring stability during connection and preventing vibration and shaking from affecting the joint position. Furthermore, the shape of the limiting groove coordinates with the right-angled trapezoid at the bottom of the stabilizing block, ensuring appropriate restraint on the stabilizing block, thereby preventing vibration or shaking from interfering with stability and ensuring the continuity of the connection. This stabilizing cylinder design effectively prevents cable interruption or loosening due to vibration or shaking during use, thus protecting the cable's integrity and the stability of signal transmission.

[0044] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0045] like Figure 1 As shown, the present invention provides a photovoltaic interface for an MPPT converter, including a photovoltaic connector body 1 and a connector housing 2, as well as a photovoltaic connector 3 and a stabilizing cylinder 4. The photovoltaic connector 3 compresses the stabilizing block 34 by the horizontal displacement of the rotating cylinder 42. The stabilizing block 34 is compressed towards the center, thereby fixing the cable. At the same time, the stabilizing block 34 drives the transmission component 39, which applies downward force to limit the movement of the stabilizing cylinder 4. In addition, the stabilizing cylinder 4 can effectively restrict and stabilize the movement of the photovoltaic connector 3, making the optical cable less susceptible to external shaking and vibration, thereby maintaining the stability of the connection.

[0046] When the cable passes through the photovoltaic connector 3, it is secured by the compression stabilizing block 34, ensuring a firm and stable connection between the cable and the connector. This helps prevent the cable from loosening due to external factors or vibration, ensuring the stability of power transmission. Furthermore, the stabilizing block 34 gradually compresses towards the center during rotation, ensuring a tight connection between the stabilizing block 34 and the cable. During this compression, the stabilizing block 34 generates a downward force by driving the transmission component 39, which acts as a limit on the stabilizing cylinder 4. This design ensures moderate compression force, preventing damage to the interface or related components due to excessive force. The introduction of the stabilizing cylinder 4 makes the photovoltaic interface more stable and reliable during installation and use. The presence of the stabilizing cylinder 4 reduces the instability of the connector under the influence of external environment or vibration, thereby improving the performance of the photovoltaic system. Through the design of the rotating cylinder 31 and the stabilizing block 34 of the photovoltaic connector 3, the connector housing 2 can achieve a certain degree of locking, effectively preventing the photovoltaic connector 3 from loosening during use. This helps avoid electrical connection instability and reduces the risk of failure. The design of the photovoltaic interface fully considers the combination of the rotating cylinder 31 and the stabilizing block 34, making the photovoltaic connector 3 more convenient to install.

[0047] like Figure 2 ,3 As shown in Figures 4, 5, and 7, the photovoltaic connector 3 includes a rotating cylinder 31, a rotating hole 32, a stabilizing pad 33, a stabilizing block 34, a pressing block 35, a fixed disc 36, a fixing groove 37, a fixing sleeve 38, and a transmission assembly 39. The rotating cylinder 31 is rotatably mounted at both ends of the connector housing 2. The cross-sectional shape of the rotating cylinder 31 is "convex," and a rotating hole 32 is opened in the center of the "convex" rotating cylinder 31. The right end of the rotating hole 32 is shaped like an inverted frustum. A stabilizing block 34 is slidably mounted inside the inverted frustum at the right end of the rotating hole 32. A stabilizing pad 33 is slidably mounted on the rotating cylinder 31. A pressing block 35 is fixedly mounted on the right end of the stabilizing block 34. A fixing disc 36 is fixedly mounted inside the pressing block 35. A fixing groove 37 is opened on the fixing disc 36. The fixing groove 37 is "U" shaped. A fixing sleeve 38 is fixedly mounted on the periphery of the pressing block 35. A transmission assembly 39 is fixedly mounted on the pressing block 35.

[0048] When the cable passes through the connector, the stabilizing block 34 can slide and be positioned within a specific direction and angle through the rotating cylinder 31 with a convex cross-section and the inverted frustum-shaped rotating hole 32, ensuring that the installation of the stabilizing block 34 is very precise, thereby guaranteeing the stability of the photovoltaic connector 3 during the connection process. The rotating cylinder 31 and the inverted frustum-shaped rotating hole 32 allow the stabilizing block 34 to fix the optical cable by compression. This compression operation is controllable, and the degree of compression can be adjusted as needed to ensure a tight connection between the stabilizing block 34 and the cable. The stabilizing block 34 is slidably installed in the inverted frustum-shaped rotating hole 32 inside the stabilizing block 34, so that the stabilizing block 34 can maintain a stable movement trajectory during the compression process. This helps to avoid instability or displacement of the stabilizing block 34, thereby ensuring the reliability of the cable connection. The compression design of the stabilizing block 34 allows the cable to be stably clamped, making it less susceptible to excessive stress and reducing cable wear or damage caused by stress. Through the compression action of the stabilizing block 34, the connection between the cable and the connector becomes more secure. Furthermore, the presence of the fixing disc 36 and the fixing groove 37 ensures that the compression block 35 has a clear positioning during compression. The U-shaped fixing groove 37 ensures the correct alignment of the stabilizing block 34 during the extrusion process, thereby guaranteeing the stability and reliability of the connection. The design of the fixing disc 36 evenly distributes the extrusion force to all parts of the stabilizing block 34, avoiding excessive local stress on the stabilizing block 34 and protecting it from damage. The presence of the fixing sleeve 38 ensures the stability of the fixing disc 36, preventing unnecessary displacement or wobbling during installation. This helps ensure that the stabilizing block 34 always maintains the correct extrusion position. The combination of the fixing sleeve 38 and the fixing disc 36 improves the durability of the entire joint system and reduces the possibility of loosening or damage during long-term use. The U-shaped design of the fixing groove 37 provides a suitable position for the stabilizing block 34, ensuring its correct alignment during the extrusion process, thus preventing the stabilizing block 34 from shifting or displacing during extrusion.

[0049] like Figure 8 As shown, the cross-sectional shape of the stabilizing block 34 is a right trapezoid, and the inclined surface of the stabilizing block 34 is arc-shaped. The stabilizing block 34 cooperates with the fan-shaped extrusion block 35 to convert the extrusion force of the stabilizing block 34 into the force of vertical displacement of the transmission component 39. Due to the extrusion action of the stabilizing block 34, the connection between the cable and the connector becomes more secure.

[0050] When the rotating cylinder 31 presses against the stabilizing block 34, the design of the right-angled trapezoidal cross-section and curved bevel of the stabilizing block 34 allows for a more uniform distribution of the pressing force across its various parts. This avoids excessive stress points and improves the durability of the stabilizing block 34. Furthermore, the engagement of the curved bevel of the stabilizing block 34 with the fan-shaped pressing block 35 ensures effective contact between the pressing block 35 and the stabilizing block 34. This design is highly adaptable, effectively transferring the pressing force even in cases of imperfect alignment. The engagement design between the pressing block 35 and the stabilizing block 34 allows the force applied by the pressing block 35 to be converted into vertical displacement of the transmission assembly 39, thereby improving transmission efficiency. This helps ensure the limiting protection of the stabilizing cylinder 4. The curved bevel of the stabilizing block 34 and the inverted frustum shape at the right end of the rotating hole 32 help avoid impacts or vibrations caused by sudden applied forces, improving operational stability. The uniform distribution of pressing force and improved transmission efficiency help reduce unnecessary stress on the stabilizing block 34 and related components, thereby improving the durability and reliability of the entire system.

[0051] like Figure 6 and 7 As shown, a limiting block 381 is installed at the bottom of the fixed sleeve 38. The shape of the limiting block 381 is consistent with the shape of the fixed groove 37, and the thickness of the limiting block 381 is greater than the thickness of the fixed disc 36, which makes the photovoltaic connector 3 easy to install and at the same time plays a stabilizing role for the photovoltaic connector 3.

[0052] When the fixing sleeve 38 secures the connector, the presence of the limiting block 381 ensures the correct positioning of the photovoltaic connector 3 during installation. Due to the consistency in shape between the limiting block 381 and the fixing groove 37, the limiting block 381 can easily slide into the fixing groove 37, making the connector installation process more convenient and faster. The shape of the limiting block 381 matches the fixing groove 37, meaning that once the limiting block 381 is inserted into the fixing groove 37, it locks the connector in a specific position, preventing movement or displacement during use. The presence of the limiting block 381 provides additional stability to the bottom of the photovoltaic connector 3, helping to ensure the connector remains stable during use, preventing instability due to external factors or vibrations, and avoiding loosening of the optical cable due to shaking. Furthermore, due to the greater thickness of the limiting block 381, it can better contact components such as the fixing disc 36, thereby improving contact stability and ensuring stable force transmission during compression. The position locking characteristic of the limiting block 381 effectively prevents the connector from loosening during use, ensuring the continuity and stability of the cable connection. The thickness of the limiting block 381 can also reduce the stress concentration problem of components such as the fixed disc 36 during the extrusion process, which helps to improve the durability and life of the joint.

[0053] like Figure 10As shown, the stabilizing pad 33 is composed of two pads, and each pad has a radially textured surface on its outer side. The radially textured surface provides the stabilizing pad 33 with anti-slip properties, which helps to maintain stability when in contact with the component, thereby preventing loosening and slippage at the contact point. The inner side has a serrated surface, which can better align the position between the stabilizing pad 33 and the stabilizing block 34, ensuring that the stabilizing block 34 can be correctly positioned during the extrusion process, thereby ensuring the stability of the connection.

[0054] As the rotating cylinder 31 rotates, the combination of the main radial ribbed surface and the helical toothed surface allows the stabilizing pad 33 to better adapt to different surfaces and components during connection and installation. The radial ribbed surface provides a wider contact area, while the helical toothed surface offers greater flexibility in terms of adaptability. The radial ribbed surface provides better anti-slip properties for the stabilizing pad 33, helping to maintain stability when in contact with components, thereby preventing loosening and slippage. At the same time, the radial ribbed surface also provides better transmission efficiency during compression and force transfer, ensuring that the compression force can be effectively transferred to the stabilizing block 34 and other related components. In addition, the radial ribbed surface can reduce stress concentration generated during contact, extending the service life of the stabilizing pad 33 and other components. The helical toothed surface can better align the position between the stabilizing pad 33 and the stabilizing block 34, ensuring that the stabilizing block 34 can be correctly positioned during compression, thereby guaranteeing the stability of the connection. The design of the radial ribbed surface and the helical toothed surface makes it easier for the stabilizing pad 33 to dock with other components, simplifying the joint installation process and reducing the potential for errors. The presence of radially textured surfaces prevents unnecessary friction or wear during the connection process, thereby protecting the stabilizing pad 33 and related components.

[0055] like Figure 3 and 11 As shown, the transmission assembly 39 includes a transmission rod 391, a connecting rod 392, a rotating hole 393, a stabilizing rod 394, a fixed cylinder 395, a compression cylinder 396, a fixing block 397, and a compression spring 398. One end of the transmission rod 391 is fixedly mounted on the compression block 35, and the other end of the transmission rod 391 is rotatably mounted with the connecting rod 392. The transmission rod has a rotating hole. The stabilizing rod 394 is fixedly mounted at the center of the connecting rod 392, and the central axis of the stabilizing rod 394 is perpendicular to the central axis of the optical cable. The other end of the connecting rod 392 is rotatably mounted with the fixed cylinder 395. The compression cylinder 396 is fixedly mounted at the lower end of the fixed cylinder 395. The fixing block 397 is installed inside the compression cylinder 396, and the compression spring 398 is engaged above the fixing block 397.

[0056] When the stabilizing block 34 is pressed towards the center, the power transmission of the stabilizing block 34 can be transmitted to the extrusion cylinder 395 of the connector through the cooperation of components such as the transmission rod 391, connecting rod 392, and stabilizing rod 393, thereby helping to ensure the stability and reliability of the extrusion process. The design of the connecting rod 392 and the stabilizing rod 393 ensures that the extrusion cylinder 395 and the stabilizing block 34 maintain good alignment, and the central axis of the stabilizing rod 393 is perpendicular to the central axis of the optical cable, ensuring the correct positioning of the stabilizing block 34. The stabilizing block 34 is installed in the groove inside the extrusion cylinder 395, and a compression spring 397 is set above the stabilizing block 34. This design can ensure that the stabilizing block 34 is adequately protected during the extrusion process, preventing excessive stress from adversely affecting the stabilizing block 34, and reducing friction on the stabilizing block 34 during rotation, thereby reducing friction loss. Through the design of the connecting rod 392 and the transmission rod 391, the power transmission can be effectively transmitted at the center position of the connecting rod 392, improving transmission efficiency and reducing energy loss.

[0057] like Figure 11 As shown, the front end of the transmission rod 391 is fan-shaped, which can provide a wider contact area during the extrusion process, thereby enabling the power to be transmitted to the fixed block 396 in the extrusion cylinder 395.

[0058] During extrusion, the fan-shaped front end of the drive rod 391 provides a wider contact area, effectively transmitting power to the stabilizing block 34 and other related components, helping to ensure the stability and reliability of the transmission. The fan-shaped front end allows for even distribution of transmitted power among the stabilizing block 34 and other contact parts, reducing stress concentration and improving the durability and lifespan of related components. The fan-shaped front end also allows for better contact with other components such as the connecting rod 392 and stabilizing rod 393, thereby improving transmission efficiency and reducing energy loss. This design provides a more stable transmission process, ensuring better power transmission and reducing vibration or uneven stress caused by transmission instability. The wider contact of the fan-shaped front end helps disperse transmitted power, reducing impact forces on related components and minimizing the risk of component damage due to excessive impact forces. The fan-shaped drive rod 391 better matches the groove shape of the stabilizing block 34, ensuring that the extrusion force is evenly transmitted to the stabilizing block 34, achieving a more stable extrusion effect.

[0059] like Figure 3 As shown, the cross-sectional shape of the fixing block 396 is "+", and the cross-sectional shape of the "+" shaped fixing block 396 can adapt to the extrusion force in different directions. The lower cross-sectional shape of the "+" shaped fixing block 396 is a right trapezoid. The right trapezoidal bottom shape of the fixing block 396 can better match the stabilizing cylinder 4, ensuring that the fixing block 396 is correctly aligned during connection and extrusion.

[0060] When the connecting rod 392 applies force to the extrusion cylinder 395, the cross-sectional shape of the "+" shaped stabilizing block 34 provides enhanced stability. This shape enhances the anti-rotation performance of the stabilizing block 34 in different directions, thereby ensuring a firm connection. The shape of the right-angled trapezoidal bottom better matches the stabilizing cylinder 4, ensuring that the stabilizing block 34 is correctly aligned during connection and extrusion. The structural design of the stabilizing block 34 allows the extrusion force to be evenly distributed to all parts of the extrusion cylinder 395, thus ensuring connection stability. In addition, the right-angled trapezoidal design of the stabilizing block 34 helps to reduce stress concentration problems, improving the durability and service life of the stabilizing block 34. The cross-sectional shape of this "+" shaped stabilizing block 34 can adapt to extrusion forces in different directions, while the right-angled trapezoidal design reduces unnecessary rotation or movement, thereby preventing contact loosening problems caused by instability. In addition, the design of the right-angled trapezoidal bottom also serves as a protective measure, reducing the risk of damage caused by improper extrusion. The right-angled trapezoidal shape at the bottom of the stabilizing block 34 makes it easier to slide into the corresponding groove during installation, thus enabling it to quickly and accurately engage with the stabilizing cylinder 4 and achieve a firm fixation.

[0061] like Figure 1 and 4 As shown, the stabilizing cylinder 4 includes a protective cylinder 41, a rotating cylinder 42, a limiting cylinder 43, and a limiting groove 44. The protective cylinder 41 is fixedly installed on the photovoltaic connector 3. A rotating cylinder 31 is installed on the left side of the protective cylinder 41, and a limiting cylinder 43 is installed on the left side of the rotating cylinder 31. A limiting groove 44 is formed on the limiting cylinder 43. The limiting groove 44 is an isosceles trapezoid. The limiting groove 44 and the right-angled trapezoid at the lower end of the fixing block 396 cooperate with each other, so that the fixing block 396 limits and stabilizes the stabilizing cylinder 4.

[0062] When the rotating cylinder 31 in the photovoltaic connector 3 presses against the stabilizing block 34, the stabilizing cylinder 4, through the design of the protective cylinder 41, rotating cylinder 42, limiting cylinder 43, and limiting groove 44, can effectively restrict and stabilize the stabilizing block 34, ensuring the stability of the connector position during the pressing process. This helps maintain the accuracy and stability of the connection. By coordinating the shape of the limiting groove 44 with the right-angled trapezoidal shape at the bottom of the stabilizing block 34, the stabilizing block 34 is constrained within the stabilizing cylinder 4, thus preventing shaking or vibration from affecting the stabilizing cylinder 4 and ensuring the continuity of the connection. The design of the stabilizing cylinder 4 prevents loosening caused by shaking or other reasons, thereby ensuring the robustness of the connection and preventing the cable from coming loose midway. The restrictive effect of the stabilizing cylinder 4 improves the overall reliability of the connector. Enhanced stability and vibration suppression help extend the service life of the stabilizing cylinder 4 and the connector, reducing the frequency of maintenance and repair. The design of the stabilizing cylinder 4 improves operational safety and reduces the risks of accidental operation or malfunction. By improving stability and reliability, the risks caused by accidental operation or malfunction can be reduced. The design of the stabilizer tube 4 effectively prevents the cable from breaking due to loosening or vibration during use, protecting the integrity of the optical cable and the reliability of signal transmission.

[0063] During operation, when the cable is connected, the cable passes through the photovoltaic connector 3 and is fixed on both sides by the stabilizing cylinder 4. Then, the rotating cylinder 31 is rotated, which presses against the stabilizing block 34. The stabilizing block 34 drives the pressing block 35 to press together towards the center. The rotation of the rotating cylinder 31 can stabilize the cable by fixing it with the stabilizing block 34. At the same time, the folding of the stabilizing block 34 will drive the transmission rod 391 in the transmission assembly 39. The transmission rod 391 will rotate and drive the connecting rod 392. The connecting rod 392 controls the height of the fixing sleeve 38 by rotating. Meanwhile, the stabilizing block 34 in the fixing sleeve 38 fixes the limiting cylinder 43 in the stabilizing cylinder 4 and fixes the limiting groove 44, which has a fixing effect on the stabilizing cylinder 4. This effectively prevents the cable from being interrupted due to loosening or vibration during use, protecting the integrity of the optical cable and the reliability of signal transmission.
