Technical Field
[0001] This application relates to the technical field of photovoltaic systems, and in particular to a photovoltaic connector that is easy to install and remove. Background Technology
[0002] With the rapid development of photovoltaic technology, photovoltaic connectors, as a key component of photovoltaic systems, play a vital role in the installation, maintenance, and operational efficiency of photovoltaic systems due to their performance and ease of use.
[0003] In the current photovoltaic (PV) field, the installation and disassembly of traditional PV connectors are typically complex, often requiring various specialized tools such as screwdrivers and pliers. This cumbersome process increases labor costs and significantly prolongs the time spent on installation and disassembly, reducing work efficiency. Furthermore, the complex assembly and disassembly operations also create inconvenience for the later maintenance of PV systems. If a system malfunctions and requires repair or connector replacement, the time-consuming and labor-intensive process leads to a substantial increase in maintenance costs, while also affecting the uptime of the PV system and reducing its overall efficiency.
[0004] Regarding the aforementioned technologies, the inventors believe that traditional photovoltaic connectors have drawbacks such as complex installation and disassembly processes, cumbersome operation steps, increased labor costs, extended installation and disassembly time, and reduced work efficiency. Utility Model Content
[0005] To address the issues of complex installation and disassembly processes, cumbersome procedures, increased labor costs, and reduced work efficiency associated with traditional photovoltaic connectors, this application provides a photovoltaic connector that is easy to install and disassemble.
[0006] This application provides a photovoltaic connector that is easy to assemble and disassemble, employing the following technical solution:
[0007] A photovoltaic connector that is easy to assemble and disassemble includes a male connector assembly, the male connector assembly including a male housing and a male nut, one end of the male housing is threaded to the male nut, and the other end is provided with multiple snap-fit parts;
[0008] A female connector assembly includes a female head housing and a female head nut. One end of the female head housing is threaded to the female head nut, and the other end has a slot for inserting and engaging the snap-fit component. The female head housing is provided with a plurality of pressing members, which are located outside the slot to press the snap-fit component.
[0009] By adopting the above technical solution, the male connector shell and male nut are threadedly connected, facilitating the fixing and sealing of the internal components of the male connector assembly. The male nut allows for adjustment of the connection tightness. The male connector shell is equipped with a snap-fit component for quick connection with the slot of the female connector assembly. The slot of the female connector shell is used for accurate insertion of the snap-fit component, ensuring mating accuracy. The female nut is threadedly connected to the female connector shell, serving to fix and seal the internal structure of the female connector assembly. A pressing component is located on the outside of the slot. When disassembly is required, pressing the pressing component releases the snap-fit component from the slot, enabling quick disassembly. This connector structure design solves the problems of complex installation and disassembly of traditional photovoltaic connectors, requiring specialized tools, cumbersome operation steps, long time consumption, high labor costs, and inconvenient maintenance. Through simple insertion, removal, and pressing operations, it improves installation and disassembly efficiency, reduces labor costs, facilitates the later maintenance of photovoltaic systems, and enhances the overall efficiency of photovoltaic system operation.
[0010] Optionally, the snap-fit component includes a guide for insertion into the slot and a snap hook for engaging with the end of the slot. One end of the guide is mounted on the male connector housing, and the other end is connected to the snap hook. The snap hook has a guide surface on its outer side.
[0011] By adopting the above technical solution, the guide plays a guiding role during connection, allowing the snap-fit component to be inserted into the slot more smoothly, improving the accuracy and efficiency of the connection. The snap-fit hook engages with the end of the slot, ensuring the firmness of the connection and preventing the connector from accidentally separating during use. The guide surface on the outside of the snap-fit hook further assists the insertion process, reducing resistance during insertion and making the operation easier and more convenient. At the same time, it can also avoid damage caused by hard collision between the snap-fit hook and the slot, extending the service life of the connector.
[0012] Optionally, one end of the pressing member is disposed on the female head housing, and the other end is movably disposed outside the slot. The movable end of the pressing member is provided with a pressing surface, which is configured to cooperate with the guide surface.
[0013] By adopting the above technical solution, the movable design of the pressing part facilitates the disassembly operation. When the connector needs to be disassembled, the operator only needs to press the pressing part, and the pressing surface of its movable end will act on the guiding surface of the hook, causing the hook to move or deform, thereby releasing the locking state with the slot. This matching setting makes the disassembly process simple and labor-saving, improves the disassembly efficiency, and has high operation accuracy. It is not easy to damage the connector and improves the maintainability of the connector.
[0014] Optionally, the threaded connection ends of the male head housing and the male head nut, and the threaded connection ends of the female head housing and the female head nut are both provided with anti-disassembly parts.
[0015] By adopting the above technical solution, the anti-disassembly component effectively prevents the male and female nuts from loosening due to vibration, external force, and other factors during use, ensuring the structural stability of the male and female connectors, avoiding problems with the overall connector structure due to loose nuts, thus ensuring reliable connection of the connector, improving the safety and stability of photovoltaic system operation, and reducing the risk of failure caused by loose connection.
[0016] Optionally, both the male head housing and the female head housing are integrally formed.
[0017] By adopting the above technical solutions, the integrated male and female housings have higher structural strength. Compared with spliced housings, they have fewer weak points and can better withstand external forces and environmental influences. At the same time, the integrated molding process helps to ensure the dimensional accuracy and shape stability of the housing, making the fit between the snap-fit parts and slots, connecting parts and mounting through holes more precise, improving the overall performance and reliability of the connector, and extending the service life of the connector.
[0018] Optionally, the male connector housing is provided with a connecting pipe, a male connector terminal is sleeved inside the connecting pipe, a crimping piece is provided outside the male connector terminal so that the male connector terminal is installed inside the connecting pipe, and a conductive ring is sleeved on the end of the male connector terminal.
[0019] By adopting the above technical solution, the connecting pipe provides a stable installation position for the male terminal, ensuring the stability of the male terminal within the male housing. The crimping tab firmly fixes the male terminal within the connecting pipe to prevent loosening, ensuring the stability of the electrical connection. The conductive ring further enhances the conductivity of the male terminal end, reduces resistance, improves current transmission efficiency, reduces power loss, and enhances the electrical performance of the photovoltaic connector.
[0020] Optionally, the female head housing has an installation through hole for inserting the connecting pipe, and a female head terminal is sleeved in the installation through hole, the female head terminal being sleeved in the conductive ring sleeve.
[0021] By adopting the above technical solution, the through hole provides an accurate docking position for the connecting pipe, ensuring the accuracy of the connection between the male and female components. The female and male terminals are fitted together by conductive rings to form a complete electrical connection path, ensuring the stable transmission of electrical energy. This tight fit not only improves the reliability of the electrical connection, but also reduces contact resistance, lowers the risk of overheating, and ensures the safe and stable operation of the photovoltaic system.
[0022] Optionally, the male nut is fitted with a male sealing element, which is disposed between the outer end of the male nut housing and the inner end of the male nut.
[0023] The female nut is fitted with a female nut seal, which is located between the outer end of the female nut housing and the inner end of the female nut.
[0024] By adopting the above technical solutions, the male and female seals play a good sealing role in the male and female assemblies, respectively, effectively preventing impurities such as moisture, dust, and sand from entering the connector, avoiding damage such as corrosion and short circuits to electrical components caused by these impurities, and improving the protection performance of the connector.
[0025] In summary, this application includes at least one of the following beneficial technical effects:
[0026] 1. This photovoltaic connector securely connects the male and female connectors by inserting a snap-fit component into the slot, greatly simplifying the installation process and improving work efficiency. The snap-fit mechanism provides reliable connection strength, preventing accidental separation during use. By pressing the pressing component, the force applied is transmitted to the snap-fit component, causing it to deform and push out of the slot, thus releasing the snap-fit and allowing the male connector to be easily removed from the female connector. This enables rapid disassembly and removal of the photovoltaic connector without the need for complex tools and operations, further improving the ease of installation and removal and reducing maintenance costs.
[0027] 2. By designing the male and female connector shells as a single unit, the male and female connector shells become complete and continuous structures, avoiding the weak points in strength caused by the connection points of spliced shells. This allows the connector to better withstand external forces, effectively preventing damage such as cracks and deformation, and enhancing the overall structural strength and stability of the connector.

[0038] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0039] This application discloses a photovoltaic connector that is easy to assemble and disassemble, referring to... Figure 1 , Figure 2 and Figure 3 The photovoltaic connector that is easy to install and disassemble includes a male connector component 1, which includes a male housing 11 and a male nut 15. One end of the male housing 11 is threaded to the male nut 15, and the other end is provided with multiple snap-fit parts 111.
[0040] The female connector assembly 2 includes a female head housing 21 and a female head nut 24. One end of the female head housing 21 is threaded to the female head nut 24, and the other end has a slot 211 for inserting and engaging the snap-fit component 111. The female head housing 21 is provided with a plurality of pressing members 212, which are located outside the slot 211 to press the snap-fit component 111.
[0041] In this easily assembled and disassembled photovoltaic connector, the male housing 11 serves as the main structure of the male connector component 1, providing an installation base and support for the male terminal 12 inside the male connector component 1. The male housing 11 also protects the internal structure, preventing external factors from damaging the internal structure, ensuring the structural stability and integrity of the male connector component 1, and enabling the male connector component 1 to be connected and cooperate with the female connector component 2 as an independent unit, thereby improving the reliability and durability of the connector.
[0042] The male nut 15 engages with the male housing 11 via a threaded connection. The male nut 15 can further secure and seal the internal components of the male housing 11, preventing dust, moisture, etc. from entering the male connector assembly 1 and affecting its electrical performance. During installation, the male nut 15 can be used to adjust the tightness of the connection between the male connector assembly 1 and other components (such as cables), thereby enhancing the protective performance of the male connector assembly 1, ensuring the stability of the electrical connection, and facilitating installation and disassembly operations, thus improving the installation efficiency and maintenance convenience of the connector.
[0043] The snap-fit connector 111 is a key component for enabling quick connection and locking between the male connector 1 and the female connector 2. When the male connector 1 and the female connector 2 are mated, the snap-fit connector 111 inserts into the slot 211 of the female connector 2 and engages with it, firmly connecting the male connector 1 and the female connector 2 together. This ensures the stability of the electrical connection, eliminating the need for additional tools. Simply inserting the male connector 1 into the female connector 2 completes the connection, greatly simplifying the installation process and improving work efficiency. Simultaneously, the snap-fit method provides reliable connection strength, preventing accidental separation of the connectors during use.
[0044] In the female connector assembly 2, the female head housing 21 serves as the main structure of the female connector assembly 2, providing installation and support for components such as the slot 211, the pressing member 212, and the female head terminal 22. The female head housing 21 can protect the internal components and provide overall structural stability, ensuring the structural integrity and stability of the female connector assembly 2, so that the female connector assembly 2 can accurately cooperate with the male connector assembly 1 to achieve reliable connection and electrical transmission.
[0045] The female nut 24 engages with the female housing 21 via a threaded connection, fixing and sealing the internal components of the female housing 21, adjusting the tightness of the connection between the female connector assembly 2 and other components, enhancing the protective performance and connection stability of the female connector assembly 2, and facilitating installation and maintenance.
[0046] Slot 211 is used to insert the snap-fit part 111 of the male connector 1, providing accurate positioning and mating space for the snap-fit part 111. During insertion, slot 211 and snap-fit part 111 interact to realize the snap-fit function, ensuring accurate docking of male connector 1 and female connector 2, making the snap-fit process smoother and more reliable, and improving the accuracy and stability of the connection.
[0047] When it is necessary to disassemble the connector, pressing the pressing member 212 can release the latching state between the latching member 111 and the slot 211, so that the male connector 1 can be smoothly pulled out from the female connector 2, realizing the quick disassembly of the connector without the need for complicated tools and operations, further improving the convenience of connector disassembly and assembly, and reducing maintenance costs.
[0048] This photovoltaic connector, through the engagement of the snap-fit component 111 and the slot 211, and the design of the pressing component 212, allows for easy installation and disassembly without the need for specialized tools. It can be completed with simple plugging and pressing operations, significantly reducing installation and disassembly time and improving work efficiency. The snap-fit mechanism of the snap-fit component 111 and the slot 211 provides sufficient connection strength, ensuring the connector maintains a stable connection under various environmental conditions (such as vibration and impact), guaranteeing the normal operation of the photovoltaic system. Furthermore, the threaded connection design of the male nut 15 and the female nut 24, along with their sealing effect on internal components, effectively prevents external factors such as dust and moisture from corroding the internal electrical components of the connector, improving the connector's protection level and service life. This easy-to-install photovoltaic connector has a simple structure and good versatility, suitable for various types of photovoltaic systems, from large-scale photovoltaic power plants to small-scale distributed photovoltaic power generation systems, and has broad application prospects.
[0049] refer to Figure 2 and Figure 4The male connector housing 11 is provided with a connecting tube 112, and a male terminal 12 is sleeved inside the connecting tube 112. The male terminal 12 passes through the male connector housing 11 and extends into the connecting tube 112. Multiple crimping tabs 121 are provided on the outside of the male terminal 12 to fix the male terminal 12 inside the connecting tube 112. A conductive ring sleeve 13 is sleeved on the end of the male terminal 12 inside. The connecting tube 112 provides a specific installation space for the male terminal 12, ensuring that the male terminal 12 can be accurately positioned inside the male connector housing 11, ensuring its positional stability, reducing connection problems caused by terminal position misalignment. The connecting tube 112 can protect the male terminal 12 from external physical damage, such as collision and squeezing, and can also prevent dust, moisture and other substances from entering to a certain extent, affecting the electrical performance of the male terminal 12. It reduces the damage to the male terminal 12 by external factors, improves the reliability of the entire connector, and extends the service life of the male terminal 12.
[0050] The male terminal 12 is one of the core components for achieving electrical connections in photovoltaic connectors. It mates with the female terminal 22 to transmit electrical energy in the photovoltaic system, serving as a crucial current flow path. Furthermore, in some photovoltaic systems, the male terminal 12 may also be used to transmit control signals or monitoring data. Its excellent electrical performance ensures efficient and stable power transmission in the photovoltaic system, reducing energy loss and improving the system's power generation efficiency. For photovoltaic systems requiring signal transmission, a reliable connection of the male terminal 12 guarantees the normal operation of all system control and monitoring functions.
[0051] The crimping tab 121 is disposed outside the male terminal 12. During installation, pressure is applied to the crimping tab 121 to firmly fix the male terminal 12 inside the connecting pipe 112, preventing the male terminal 12 from loosening or shifting during use. This ensures the stability of the electrical connection. The firm fixation and good electrical contact ensure the stability of the male terminal 12 during long-term use, reduce failures caused by loose terminals or poor contact, and improve the overall reliability of the connector.
[0052] The conductive ring 13 is usually made of a highly conductive material, which can further reduce the resistance at the end of the male terminal 12 and improve the efficiency of current transmission. It can prevent the end of the male terminal 12 from being damaged by oxidation, corrosion and other factors, and extend the service life of the male terminal 12.
[0053] Through the coordinated operation of the connecting fitting 112, male terminal 12, crimping plate 121, and conductive ring 13, the photovoltaic connector can achieve a reliable electrical connection. As the core conductive component, the male terminal 12, under the protection and positioning of the connecting fitting 112, and with the fixation of the crimping plate 121 and the assistance of the conductive ring 13, can efficiently and stably transmit electrical energy and signals, thus ensuring the normal operation of the photovoltaic system.
[0054] A sealing ring 17 is fitted over the outside of the connecting pipe 112, and the female connector housing 21 is fitted over the outside of the connecting pipe 112 through the sealing ring 17. The sealing ring 17 forms a sealing barrier at the connection between the connecting pipe 112 and the female connector housing 21, preventing liquids such as moisture, rainwater, and dew from entering the connector. Photovoltaic systems are usually installed outdoors and face various harsh weather conditions. The sealing ring 17 can effectively prevent water intrusion from damaging the male terminal 12, female terminal 22, and other electrical components, such as causing short circuits and corrosion.
[0055] The sealing ring 17 also prevents dust, sand, fine particles, and other impurities from entering the connector. Dust accumulation can affect electrical contact performance, leading to increased contact resistance and consequently, overheating and increased power loss. The sealing ring 17 can reduce the occurrence of such situations. In addition, the sealing ring 17 can also buffer the vibration and impact between the female connector housing 21 and the connecting tube 112 to a certain extent. During the operation of the photovoltaic system, it may be affected by vibrations caused by wind, equipment operation, etc. The sealing ring 17 can absorb some energy, protect the stability of the internal structure of the connector, and reduce the loosening or damage of components caused by vibration. The sealing ring 17 makes the connection between the female connector housing 21 and the connecting tube 112 tighter, fills the gap between them, prevents shaking or displacement caused by the gap, and ensures the mechanical stability of the connector.
[0056] refer to Figure 3 and Figure 5 The female connector housing 21 has a mounting through hole 213 for inserting the connecting pipe 112. A female terminal 22 is fitted into the mounting through hole 213 and is fitted into the conductive ring 13. The mounting through hole 213 provides an accurate insertion path and positioning space for the connecting pipe 112, ensuring that the male connector 1 can accurately mate with the female connector 2. During installation, the connecting pipe 112 is guided smoothly into the female connector housing 21, ensuring that the male terminal 12 and the female terminal 22 are precisely aligned. The connecting pipe 112 is confined within a specific channel to prevent unnecessary collisions or interference with other components within the female connector housing 21 during insertion, thereby protecting the integrity of the electrical components and structure within the female connector housing 21.
[0057] As a key component that mates with the male terminal 12, the female terminal 22 undertakes the important tasks of power transmission and signal transmission. After being tightly connected with the male terminal 12, it forms a complete electrical circuit, allowing the current in the photovoltaic system to flow smoothly through the connector. In some photovoltaic systems that require the transmission of control signals or monitoring data, the female terminal 22 is also responsible for accurately transmitting these signals to ensure the normal operation and monitoring of the system.
[0058] The conductive ring 13 has good conductivity, and the female terminal 22 is fitted inside it, which increases the contact area between the two, reduces contact resistance, helps reduce heat generation caused by poor contact, and improves the efficiency and stability of power transmission. The tight fit makes the connection between the female terminal 22 and the male terminal 12 more secure, and can withstand a certain amount of external force, vibration and impact, preventing loosening or separation during use and ensuring the reliability of the electrical connection. The conductive ring 13 can also protect the contact area between the female terminal 22 and the male terminal 12 to a certain extent, preventing damage from oxidation, corrosion and other factors, and extending the service life of the terminals.
[0059] Through the coordinated operation of the through-hole 213, the female terminal 22, and the conductive ring 13, the male connector 1 and the female connector 2 can achieve accurate and reliable connection, forming an efficient electrical connection. This ensures the stable transmission of electrical energy and signals in the photovoltaic system, providing a solid foundation for its normal operation. Reliable electrical connection and good protection performance reduce the probability of failures caused by connection problems, improving the stability and reliability of the photovoltaic system. Even in complex outdoor environments, it ensures continuous and stable power generation.
[0060] refer to Figure 4 The male nut 15 is fitted with a male seal 14, which is located between the outer end of the male housing 11 and the inner end of the male nut 15. This seal effectively prevents external impurities such as moisture, dust, and sand from entering the male connector assembly 1. In complex outdoor environments, photovoltaic connectors may be exposed to harsh conditions such as rain, humid air, and sand. The seal acts as a barrier, protecting the electrical components inside the male connector assembly 1 (such as the male terminal 12 and conductive ring 13) from corrosion. The male seal 14 prevents moisture from entering the male connector assembly 1, avoiding rust and oxidation of electrical components due to moisture, which can affect their conductivity and lifespan. Moisture may increase the contact resistance of electrical connections, generating heat and even causing short circuits. The male seal 14 also acts as a buffer and shock absorber, reducing damage to the internal structure of the male connector assembly 1 caused by vibration, impact, and other external forces. When the photovoltaic system is affected by wind or equipment vibration, the seal can absorb some energy, protecting the stability of the internal components.
[0061] The male nut 15 presses the male seal 14 tightly against the outer end of the male housing 11, ensuring that the seal can perform its sealing function. Through the threaded connection, the male nut 15 can provide sufficient pressure to ensure a tight fit between the seal, the male housing 11, and the male nut 15. The male nut 15 itself also provides a certain degree of protection, preventing external objects from directly impacting the male assembly 1, thus providing physical protection for the internal structure.
[0062] refer to Figure 5 The female head nut 24 is fitted with a female head seal 23. The female head seal 23 is located between the outer end of the female head housing 21 and the inner end of the female head nut 24. The female head seal 23 can prevent moisture, dust, humidity and other substances from entering the female connector assembly 2 and protect the electrical components (such as the female head terminal 22) inside the female connector assembly 2. The female head seal 23 can absorb vibration and impact energy, reduce the impact on the internal structure of the female connector assembly 2 and ensure the stability of the electrical connection.
[0063] The female nut 24 presses the female seal 23 onto the female housing 21 through a threaded connection, ensuring the sealing effect of the seal. The female nut 24 provides physical protection for the female connector 2, preventing impact and damage from external objects.
[0064] Both the male connector housing 11 and the female connector housing 21 are integrally formed. In this application, they are integrally injection molded, making the male connector housing 11 and the female connector housing 21 a complete and continuous structure, avoiding the weak points in strength caused by the connection points of spliced housings. This continuous structure can better withstand external forces, such as compression during installation, vibration and impact in the usage environment, effectively preventing damage such as cracks and deformation of the housing, enhancing the overall structural strength and stability of the connector, and ensuring reliable operation under various complex conditions.
[0065] In photovoltaic systems, waterproof and dustproof sealing performance is crucial. The one-piece injection-molded shell eliminates seams, reducing the channels for external impurities such as moisture, dust, and sand to enter the connector. Combined with other sealing measures (such as sealing ring 17), it can significantly improve the sealing performance of the connector, better protect internal electrical components (such as male terminal 12, female terminal 22, etc.), prevent electrical faults such as short circuits and corrosion caused by impurities, and extend the service life of the connector.
[0066] One-piece injection molding is a relatively simple process, reducing the number of processing steps and assembly stages compared to traditional multi-part processing and reassembly methods. This not only shortens the production cycle and improves production efficiency but also reduces labor and material costs in the production process, such as reducing the cost of parts processing equipment and assembly labor. At the same time, the reduced number of parts and assembly steps also lowers the defect rate caused by parts mismatch issues, further improving economic efficiency.
[0067] The snap-fit component 111 includes a guide 1111 for insertion into the slot 211 and a hook 1112 for snapping into the end of the slot 211. One end of the guide 1111 is mounted on the male housing 11, and the other end is connected to the hook 1112. The hook 1112 has a guide surface 1113 on its outer side. The snap-fit component 111 is inclined relative to the male housing 11 and is flexible, which facilitates disassembly. When the male connector 1 and the female connector 2 are mated, the guide 1111 provides accurate positioning and guidance for the snap-fit component 111 to be inserted into the slot 211, ensuring that the snap-fit component 111 can be smoothly inserted into the slot 211 along the correct path, avoiding snap-fit failure or damage to components due to insertion angle deviation.
[0068] As part of the snap-fit component 111, the guide component 1111 connects the male housing 11 and the snap hook 1112 to form a complete snap-fit structure, enabling the snap hook 1112 to stably perform its snap-fit function.
[0069] The latch 1112 is a key component for locking the male connector 1 and the female connector 2 together. When the latch 111 is inserted into the slot 211, the latch 1112 engages with the end of the slot 211, securely connecting the male connector 1 and the female connector 2 together and preventing accidental separation during normal use. The latching action of the latch 1112 provides reliable connection strength to the connector, ensuring a stable connection even under external forces such as pulling, vibration, or impact, thus guaranteeing normal electrical connection of the photovoltaic system.
[0070] During the insertion of the snap-fit connector 111 into the slot 211, the guide surface 1113 serves as a guide and transition, making it easier for the snap hook 1112 to enter the slot 211, reducing resistance during insertion, making the insertion process smoother, greatly shortening installation time, and improving work efficiency. During insertion, the guide surface 1113 prevents excessive friction or collision between the snap hook 1112 and the edge of the slot 211, thereby protecting the structure of the snap hook 1112 and the slot 211 and extending their service life.
[0071] One end of the pressing member 212 is mounted on the female head housing 21, and the other end is movably mounted on the outside of the slot 211. The movable end of the pressing member 212 is provided with a pressing surface 2121, which is configured to cooperate with the guide surface 1113. The fact that one end of the pressing member 212 is mounted on the female head housing 21 provides a stable support base for the entire pressing member 212, ensuring that the pressing member 212 has a fixed position on the female head housing 21. This prevents the pressing member 212 from shaking or shifting during operation, thus ensuring its working stability. Due to the stable support, when the operator presses the pressing member 212, the pressing member 212 can accurately perform the action in the designed manner, avoiding the inability to effectively release the jamming due to loosening or shifting, and improving the reliability of the disassembly operation.
[0072] The movable end of the pressing member 212 can move flexibly. When the operator presses the movable end, the pressing force can be effectively transmitted to the snap-fit member 111. The pressing surface 2121 is the part that directly contacts the guide surface 1113 of the snap-fit member 111. It concentrates the pressing force on the guide surface 1113, thereby realizing the operation of the snap-fit member 111.
[0073] Through the engagement of the crimping surface 2121 and the guide surface 1113, the pressing member 212 can deform or move the latch 1112 of the locking member 111, thereby releasing the latch 1112 from the end of the slot 211, allowing the male connector 1 to be pulled out from the female connector 2. This design makes disassembling the photovoltaic connector very convenient. The operator only needs to press the movable end of the pressing member 212 to easily release the latch without the need for additional tools, greatly improving disassembly efficiency. The engagement of the crimping surface 2121 and the guide surface 1113 can apply precise pressing force, avoiding damage to the locking member 111 or the slot 211 due to improper force, and extending the service life of the connector.
[0074] The shape and angle of the guide surface 1113 can guide the pressing surface 2121 to apply the pressing force accurately, so that the snap-fit 111 deforms or moves in the expected way, ensuring that the snap-fit release process is carried out smoothly. This kind of cooperation can effectively transfer the pressing force on the pressing part 212 to the snap-fit 111, realize the snap-fit release with the minimum force, improve the efficiency and labor saving of operation, reduce the labor intensity of operation, and improve the comfort of operation.
[0075] The rapid disassembly of the photovoltaic connector is achieved through the coordinated operation of the pressing component 212, the crimping surface 2121, and the guiding surface 1113. During the installation and maintenance of the photovoltaic system, when it is necessary to replace or repair the connector, operators can quickly release the latch by pressing the pressing component 212, saving a significant amount of time and labor costs. This convenient disassembly method makes connector maintenance easier; whether it's inspecting, cleaning, or replacing internal components, it can be completed quickly without damaging the connector, improving the overall maintainability of the photovoltaic system.
[0076] Anti-disassembly elements 16 are provided at the threaded connection ends of the male housing 11 and male nut 15, and at the threaded connection ends of the female housing 21 and female nut 24. During the operation of the photovoltaic system, the photovoltaic connector may be subjected to external forces such as vibration and impact. Under the influence of these external forces, the threaded connection between the male housing 11 and male nut 15, and between the female housing 21 and female nut 24, is at risk of loosening on its own. The anti-disassembly elements 16 can increase the friction and engagement force of the threaded connection, effectively preventing the threads from loosening under vibration or impact, ensuring that the male nut 15 tightly fixes the male housing 11, and the female nut 24 tightly fixes the female housing 21, maintaining the stability of the overall connector structure.
[0077] Furthermore, during routine maintenance or operation, accidental loosening of the nuts due to misoperation may cause the male and female connectors to separate. The presence of the tamper-evident component 16 increases the difficulty of disassembly, requiring specific procedures to remove its tamper-evident function. This reduces the possibility of connector separation due to misoperation and ensures the normal connection status of the photovoltaic system. If the connector accidentally separates during operation, it may cause electrical faults, or even short circuits, leakage, and other safety issues. The tamper-evident component 16 prevents such accidental separation, ensuring the safety of the photovoltaic system during operation, reducing potential safety hazards, and protecting the safety of personnel and equipment.
[0078] This application provides an easy-to-assemble and disassemble photovoltaic connector: the male connector 1 uses a snap-fit part 111 on the male connector 1 to engage with a slot 211 on the female connector 2. The snap-fit part 111 includes a guide part 1111 and a hook 1112. The guide part 1111 acts as a guide during insertion, guiding the hook 1112 to accurately enter the slot 211. The guide surface 1113 on the outer side of the hook 1112 engages with the pressing surface 2121 of the pressing part 212 on the female connector housing 21. When the male connector 1 is inserted into the female connector 2, the guide surface 1113 makes the insertion process smoother. After insertion, the hook 1112 engages with the end of the slot 211, realizing a quick connection between the male connector 1 and the female connector 2 and ensuring the stability of the electrical connection.
[0079] When disassembly is required, press the pressing member 212 located outside the slot 211 on the female housing 21. The movable end of the pressing member 212 is provided with a pressing surface 2121. The pressing surface 2121 cooperates with the guide surface 1113 of the hook 1112. By pressing, the hook 1112 is deformed or displaced to release the hook 1112 from the end of the slot 211. At this time, the male component 1 can be easily pulled out from the female component 2, realizing quick disassembly.
[0080] Both the male connector housing 11 and the female connector housing 21 are integrally formed using injection molding, resulting in high structural strength and effective protection for the internal electrical connection components. The male nut 15 is threaded to the male connector housing 11, and the female nut 24 is threaded to the female connector housing 21. An anti-disassembly element 16 is provided at the threaded connection end to prevent loosening and ensure a secure connection. Simultaneously, the male seal 14 inside the male nut 15 and the female seal 23 inside the female nut 24 form seals between the male connector housing 11 and the male nut 15, and between the female connector housing 21 and the female nut 24, respectively, preventing moisture, dust, and other impurities from entering the connector and ensuring stable electrical performance. The sealing ring 17, fitted outside the connecting tube 112, further enhances the sealing effect and improves the connector's protective performance when the female connector housing 21 is fitted outside the connecting tube 112.
[0081] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
