Description

Technical Field

[0001] This invention relates to the field of electrical connection technology, and in particular to a photovoltaic connector assembly. Background Technology

[0002] In applications such as module connection, equipment wiring, current collection, and energy storage interfaces, photovoltaic systems typically require various connector structures to achieve reliable conductive connections between different lines. As photovoltaic equipment develops towards modularization, integration, and long-term outdoor operation, connectors are no longer just standalone plug-in components. They increasingly need to be installed as components on mounting panels or equipment housings, simultaneously meeting multiple requirements such as stable fixation, convenient plugging, reliable conductivity, and a certain level of sealing performance.

[0003] In existing technologies, male and female connectors are typically arranged separately, with their rear-end power connection structures also being relatively dispersed. This can easily lead to problems such as insufficient concentration during installation, unstable fixation of the rear-end power contacts, and inconvenience in wiring organization. Furthermore, some connectors use a rigid connection between the internal power contacts and terminals, which can easily lead to stress concentration at the connection point during actual insertion, vibration, or long-term use, thus affecting conductivity stability. For male and female connectors that need to be installed on the same panel, the lack of a unified panel mounting structure and rear-end fixing structure can also affect overall assembly efficiency and reliability. On the other hand, photovoltaic systems are mostly located in outdoor environments, placing higher demands on the sealing performance of the connector insertion points and the stability of the panel installation. Summary of the Invention

[0004] To address the aforementioned issues, the present invention provides a photovoltaic connector assembly that offers advantages such as convenient integrated installation, reliable conductive connection, stable structure, and suitability for photovoltaic applications.

[0005] The technical solution adopted in this invention is: a photovoltaic connector assembly, including a mounting panel, at least one male connector, at least one female connector, and a power connection panel. The mounting panel is provided with a first through slot and a second through slot. The male connector is disposed in the first through slot and fixed to the mounting panel by a first fixing element. The female connector is disposed in the second through slot and fixed to the mounting panel by a second fixing element. The power connection panel is used to fix the first power connection piece of the male connector and the second power connection piece of the female connector.

[0006] A further improvement to the above solution is that the male connector includes a male housing, a male wiring fixing base, a male electrical terminal, a first electrical contact piece, and a male flexible connector. The male housing has a male fixing connection cavity, a male fixing part, and a male insertion cavity sequentially arranged and connected at its tail center. The male wiring fixing base has a male wiring cavity and a male electrical fixing groove. One end of the male wiring fixing base is inserted into the male fixing connection cavity so that the male fixing connection cavity is opposite to and connected to the male fixing part. The male electrical terminal is installed in the male fixing part, with the male wiring part of the male electrical terminal extending towards the male wiring cavity and the male insertion end extending towards the male insertion cavity. The first electrical contact piece is fixed in the male electrical fixing groove. The male flexible connector is used to connect the first electrical contact piece to the male wiring part of the male electrical terminal.

[0007] The female connector includes a female housing, a female wiring fixing base, a female electrical terminal, a second electrical contact piece, and a female flexible connector. At the center of the tail of the female housing, a female fixing cavity, a female fixing part, and a female insertion cavity are sequentially arranged and connected.

The female electrical terminal is installed in the female fixing part, with the female wiring part of the female electrical terminal extending towards the female wiring cavity and the female insertion end extending towards the female insertion cavity. The second electrical contact piece is fixed in the female electrical fixing groove. The female flexible connector is used to connect the second electrical contact piece to the female wiring part of the female electrical terminal. Both the male flexible connector and the female flexible connector are flexible conductors formed by braiding multiple wires.

[0008] A further improvement to the above solution is that the portion of the female connector housing located outside the female connector insertion cavity forms a female connector, the female connector housing is provided with insertion buckles on both sides of the female connector, and the end of the female connector is provided with a sealing portion.

[0009] A further improvement to the above solution is that the male connector housing is provided with insertion slots on both sides of the male connector insertion cavity, the insertion slots extending along the connector insertion direction, and through slots provided on both sides of the male connector housing, the through slots penetrating along the vertical direction of the insertion slots for locking and limiting during insertion.

[0010] A further improvement to the above solution is that a sealing groove is provided at the port of the male connector cavity and / or the female connector cavity.

[0011] A further improvement to the above solution is that the male connector fixing connection cavity is provided with a male connector positioning guide strip and a male connector fixing slot, and the male connector fixing base is provided with a male connector positioning plane and a male connector fixing buckle. The male connector positioning plane is used for directional positioning when the male connector positioning guide strip is inserted, and the male connector fixing buckle is used to cooperate with the male connector fixing slot to fix the male connector fixing base in the male connector fixing connection cavity. The female connector fixing cavity is provided with a female connector positioning guide strip and a female connector fixing slot. The female connector wiring fixing seat is provided with a female connector positioning plane and a female connector fixing buckle. The female connector positioning plane is used for directional positioning when the female connector positioning guide strip is inserted. The female connector fixing buckle is used to cooperate with the female connector fixing slot to fix the female connector wiring fixing seat in the female connector fixing cavity.

[0012] A further improvement to the above solution is that multiple male head positioning guide strips are provided, and the multiple male head positioning guide strips are spaced apart to form male head positioning guide grooves. Male head positioning protrusions are provided on the male head positioning plane, and the male head positioning protrusions are used to cooperate with the male head positioning guide grooves. The female head positioning guide strip is provided in multiple ways, and the multiple female head positioning guide strips are spaced apart to form a female head positioning guide groove. A female head positioning protrusion is provided on the female head positioning plane, and the female head positioning protrusion is used to cooperate with the female head positioning guide groove.

[0013] A further improvement to the above solution is that the male connector fixing base is provided with a plurality of male connector clamping springs, and the plurality of male connector clamping springs surround to form the male connector power connection fixing groove, which is used to clamp and fix the first power connection piece. The female connector fixing base is provided with multiple female connector clamping springs, which surround to form the female connector power connection fixing groove for clamping and fixing the second power connection piece.

[0014] A further improvement to the above solution is that both the male connector and the female connector have a mounting portion at one end near the mounting panel, the mounting portion being in contact with one side of the mounting panel, and the first fixing element and the second fixing element being used to fix the mounting portion of the male connector and the mounting portion of the female connector on the mounting panel, respectively.

[0015] A further improvement to the above solution is that the mounting part of the male connector includes a male mounting platform, and male mounting posts are provided on both sides of the male mounting platform. Male mounting holes are provided on the male mounting posts. The mounting part of the female connector includes a female mounting platform, and female mounting posts are provided on both sides of the female mounting platform. Female mounting holes are provided on the female mounting posts. The first fixing element and the second fixing element are screws, which are respectively connected to the male mounting holes and the female mounting holes to fix the male mounting platform and the female mounting platform on the mounting panel.

[0016] The beneficial effects of this invention are: Compared to existing technologies, this invention provides a first through slot and a second through slot on the mounting panel, where male and female connectors are installed respectively, enabling the male and female connectors to be integrated on the same mounting panel. Compared to distributed installation methods, this structure improves the overall integration of photovoltaic connection interfaces, facilitating unified layout and modular installation.

[0017] The male connector is fixed to the mounting panel by a first fixing element, and the female connector is fixed to the mounting panel by a second fixing element, forming a relatively clear mounting relationship. In particular, the structure in which the mounting part fits snugly against the mounting panel and is then fixed by screws and mounting holes helps to improve the firmness of the male and female connectors on the panel, reducing the risk of loosening due to vibration, pulling, or environmental changes during use.

[0018] This invention provides a power-connecting panel for fixing the first power-connecting piece of the male connector and the second power-connecting piece of the female connector, allowing multiple rear-end power-connecting parts to be supported and organized on the same structure. This not only facilitates a neat arrangement of the rear-end structure but also improves the installation stability of the first and second power-connecting pieces, reducing the swaying of the conductive tail.

[0019] The male connector has a flexible male connector inside, and the female connector has a flexible female connector inside, both of which use a flexible conductor structure formed by braiding multiple wires. Compared with rigid connections, this structure can provide a certain degree of flexibility compensation when plugged in, subjected to vibration, external force, or assembly deviations, which helps to reduce stress concentration at the conductive connection points and improve the stability of the conductive connection.

[0020] The female connector's outer shell is equipped with a plug-in latch and a female plug, while the male connector's outer shell is equipped with a plug-in slot and a through slot. When the two are plugged in, they can form a corresponding locking and limiting relationship, which helps to improve the holding force after plugging in and prevents the connector from accidentally coming loose during use.

[0021] The female connector has a sealing part at its end, and the male connector cavity and / or the female connector cavity port have a sealing groove. When the male connector and the female connector are plugged in, a corresponding sealing fit structure can be formed, which helps to improve the dustproof, moisture-proof and environmental adaptability of the connector assembly, and is more suitable for outdoor use environments such as photovoltaic systems.

[0022] The male and female connectors are respectively equipped with positioning guide strips and fixing slots. The male and female connector fixing bases are respectively equipped with positioning planes, positioning protrusions and fixing buckles. These features enable directional guidance, error prevention positioning and snap-fit ​​fixing during assembly, thereby improving assembly efficiency and enhancing the assembly consistency of the internal structures of the male and female connectors.

[0023] Multiple male clamping springs on the male connector mounting base form a male connector fixing groove for clamping and fixing the first connector piece; multiple female clamping springs on the female connector mounting base form a female connector fixing groove for clamping and fixing the second connector piece. This structure helps to maintain the first and second connector pieces in a stable position within their respective connectors, thereby improving overall conductivity reliability.

[0024] This invention integrates multiple structural features such as panel mounting, flexible conductivity, plug-in locking, and sealing fit, which can better meet the requirements of photovoltaic connectors for installation stability, conductivity reliability, and environmental protection performance in outdoor working conditions, and has strong practical value.

[0029] Power connection panel 4. Detailed Implementation

[0030] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0031] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0033] This invention provides a photovoltaic connector assembly, primarily used for interface connection scenarios in photovoltaic systems, such as equipment enclosure interfaces, photovoltaic module interfaces, controller interfaces, combiner unit interfaces, or other applications requiring the integration of male and female connectors in the same mounting location. Unlike conventional structures that only protect a single male or female connector, the focus of this invention is on integrating at least one male connector 2 and at least one female connector 3 via a mounting panel 1, and uniformly fixing the rear power connection points via a power connection panel 4, thereby forming a relatively complete panel-type photovoltaic connector assembly.

[0034] See Figures 1-13As shown, the photovoltaic connector assembly of the present invention includes a mounting panel 1, at least one male connector 2, at least one female connector 3, and a power connection panel 4. The mounting panel 1 is the mounting base of the entire assembly and can be understood as part of an equipment panel, housing panel, support plate, or mounting base plate, used to support the male connector 2 and the female connector 3. The mounting panel 1 is provided with a first through slot 11 and a second through slot 12. The first through slot 11 is used to install the male connector 2, and the second through slot 12 is used to install the female connector 3. Depending on actual application requirements, the mounting panel 1 may have one first through slot 11 and one second through slot 12, or multiple first through slots 11 and multiple second through slots 12, to accommodate the arrangement requirements of multiple male connectors 2 and multiple female connectors 3.

[0035] The male connector 2 is disposed within the first through slot 11 and fixed to the mounting panel 1 by the first fixing element 13; the female connector 3 is disposed within the second through slot 12 and fixed to the mounting panel 1 by the second fixing element 14. Both the male connector 2 and the female connector 3 are mounted to the mounting panel 1 via a through-plate method, thus establishing a clear positional relationship between them on the front and rear sides or opposite sides of the mounting panel 1. The first fixing element 13 and the second fixing element 14 can be screws, bolts, or other fasteners suitable for fixed installation; in this embodiment, screws are preferred.

[0036] The power connection panel 4 is used to fix the first power connection piece 24 of the male connector 2 and the second power connection piece 34 of the female connector 3. The power connection panel 4 can be set on the rear side of the mounting panel 1 or the wiring side. Its main function is to provide unified support, positioning or arrangement for the power connection pieces at the rear end of multiple connectors, so as to make the rear conductive structure more stable and the arrangement more regular.

[0037] With the above-described integrated structure, male connector 2 and female connector 3 are no longer installed separately, but rather form a modular structure. This improves installation efficiency, reduces relative installation errors between different connectors, and facilitates subsequent maintenance and modular replacement.

[0038] See Figure 6 , Figures 8-10As shown, the male connector 2 includes a male housing 21, a male connector mounting base 22, a male connector terminal 23, a first connector piece 24, and a male flexible connector 25. At the center of the rear of the male housing 21, a male fixing cavity 211, a male fixing part 212, and a male insertion cavity 213 are sequentially arranged and connected. Here, "sequentially arranged and connected" means that along the axial direction of the male connector 2, multiple functional areas are formed sequentially from back to front for rear fixing, male connector terminal installation, and front insertion. The male fixing cavity 211 is used to install the male connector mounting base 22, the male fixing part 212 is used to install the male connector terminal 23, and the male insertion cavity 213 is used to form a mating connection with the female connector 3.

[0039] The male connector fixing base 22 is provided with a male connector cavity 221 and a male connector fixing groove 222. One end of the male connector fixing base 22 is inserted into the male connector fixing connection cavity 211, so that the male connector fixing connection cavity 211 is opposite to and communicates with the male connector fixing part 212. The male connector terminal 23 is installed in the male connector fixing part 212, and the male connector portion 231 of the male connector terminal 23 extends toward the male connector cavity 221, and the male connector insertion end 232 extends toward the male connector insertion cavity 213. The first connector piece 24 is fixed in the male connector fixing groove 222, and the male connector flexible connector 25 is used to connect the first connector piece 24 to the male connector portion 231 of the male connector terminal 23.

[0040] The male flexible connector 25 is a flexible conductor formed by braiding multiple wires. Due to the braided flexible conductor structure, the male flexible connector 25 can not only conduct electricity, but also bend and deform within a certain range. Therefore, for the internal connection relationship of the male connector 2, a relatively stable flexible transition conductive structure can be formed between the male electrical terminal 23 and the first electrical contact piece 24.

[0041] See Figure 7 , Figures 11-13 As shown, the female connector 3 includes a female housing 31, a female wiring fixing base 32, a female electrical terminal 33, a second electrical contact piece 34, and a female flexible connector 35. At the center of the rear end of the female housing 31, a female fixing connection cavity 311, a female fixing part 312, and a female insertion cavity 313 are sequentially arranged and connected. Its structural partitioning logic corresponds to that of the male connector 2, but it corresponds to the mounting and insertion structure of the female connector 3 itself.

[0042] The female connector mounting base 32 is provided with a female connector cavity 321 and a female connector fixing groove 322. One end of the female connector mounting base 32 is inserted into the female connector fixing cavity 311, so that the female connector fixing cavity 311 is opposite to and communicates with the female connector fixing part 312. The female connector terminal 33 is installed in the female connector fixing part 312, and the female connector wiring part 331 of the female connector terminal 33 extends toward the female connector cavity 321, and the female connector plug end 332 extends toward the female connector plug cavity 313. The second connector piece 34 is fixed in the female connector fixing groove 322, and the female connector flexible connector 35 is used to connect the second connector piece 34 to the female connector wiring part 331 of the female connector terminal 33.

[0043] The female flexible connector 35 is also a flexible conductor formed by braiding multiple wires, so the female connector 3 also has a similar flexible conductive transition capability as the male connector 2.

[0044] In this invention, both the male flexible connector 25 and the female flexible connector 35 employ a flexible conductor structure formed by braiding multiple wires. Compared with traditional rigid sheet connections or direct hard connections, this structure has the following characteristics: First, the flexible connector can accommodate assembly errors to a certain extent when connecting the male connector terminal 23 to the first connector piece 24, and when connecting the female connector terminal 33 to the second connector piece 34. Since there are assembly tolerances between the male connector fixing base 22, the male connector fixing part 212, and the male connector terminal 23, rigid connections tend to require high structural positional accuracy, while the flexible connector is more likely to absorb such errors.

[0045] Secondly, photovoltaic connector components may be affected by vibration, temperature changes, and external pulling forces during use. Flexible connectors can provide a buffering effect under these conditions, thereby reducing stress concentration at internal conductive connections and improving long-term reliability.

[0046] Furthermore, the braided conductor structure is easy to bend and arrange in the narrow space inside the connector, without imposing stronger restrictions on the wiring path as rigid conductive sheets.

[0047] The portion of the female connector housing 31 located outside the female connector insertion cavity 313 forms the female connector insertion part 314. The female connector housing 31 has insertion latches 315 on both sides of the female connector insertion part 314, and the end of the female connector insertion part 314 has a sealing part 316.

[0048] The female connector 314 serves as the front insertion structure of the female connector 3, extending into the corresponding insertion area of ​​the male connector 2 when mated with it. Insertion latches 315 are located on both sides of the female connector 314, used to lock into place with the insertion slots 214 on the male connector 2 after insertion. This prevents the connector from disengaging under vibration or external force.

[0049] The female connector 314 has a sealing part 316 at its end, which mates with the sealing groove 216 or corresponding sealing position on the male connector 2 during insertion to improve the sealing performance of the insertion interface. For photovoltaic applications, this structure helps to improve the waterproof and dustproof capabilities of the connection parts.

[0050] The male connector housing 21 has insertion slots 214 on both sides of the male connector insertion cavity 213, which extend along the connector insertion direction. Through slots 215 are provided on both sides of the male connector housing 21, which extend vertically through the insertion slots 214 and are used for locking and limiting during insertion.

[0051] When the female connector 3 is inserted into the male connector 2, the insertion latch 315 enters the insertion slot 214 along the insertion direction, and after reaching its position, it forms a limiting relationship through the location of the through slot 215, thereby achieving locking. Since the through slot 215 passes through the vertical direction of the insertion slot 214, it provides corresponding space for the elastic insertion and limiting of the insertion latch 315.

[0052] Furthermore, sealing grooves 216 and 317 are provided at the ports of the male connector cavity 213 and / or the female connector cavity 313. In the plugged-in state, the sealing part 316 on the female connector 314 can fit with the sealing groove 216 or 317, thereby further improving the sealing performance of the plug.

[0053] The male connector fixing cavity 211 is provided with a male connector positioning guide strip 217 and a male connector fixing slot 218, and the male connector fixing base 22 is provided with a male connector positioning plane 223 and a male connector fixing buckle 224. The male connector positioning plane 223 is used for directional positioning when the male connector positioning guide strip 217 is inserted, and the male connector fixing buckle 224 is used to cooperate with the male connector fixing slot 218 to fix the male connector fixing base 22 in the male connector fixing cavity 211.

[0054] Furthermore, multiple male head positioning guide strips 217 are provided, and multiple male head positioning guide strips 217 are spaced apart to form male head positioning guide grooves 219. Male head positioning protrusions 225 are provided on the male head positioning plane 223, and the male head positioning protrusions 225 are used to cooperate with the male head positioning guide grooves 219.

[0055] With the above structure, when the male connector fixing base 22 is installed into the male connector fixing connection cavity 211, it can first form directional guidance and anti-misalignment positioning through the cooperation between the male connector positioning plane 223 and the male connector positioning guide strip 217, and the male connector positioning protrusion 225 and the male connector positioning guide groove 219. Then, it can be stably fixed by engaging with the male connector fixing buckle 224 and the male connector fixing groove 218. This can ensure that the assembly posture between the male connector fixing base 22 and the male connector housing 21 is clear and that it is not easy to loosen after assembly.

[0056] The female connector fixing cavity 311 is provided with a female connector positioning guide strip 318 and a female connector fixing slot 319, and the female connector wiring fixing seat 32 is provided with a female connector positioning plane 323 and a female connector fixing buckle 324. The female connector positioning plane 323 is used for directional positioning when the female connector positioning guide strip 318 is inserted, and the female connector fixing buckle 324 is used to cooperate with the female connector fixing slot 319 to fix the female connector wiring fixing seat 32 in the female connector fixing cavity 311.

[0057] Furthermore, multiple female head positioning guide strips 318 are provided, and the multiple female head positioning guide strips 318 are spaced apart to form female head positioning guide grooves 320. Female head positioning protrusions 325 are provided on the female head positioning plane 323, and the female head positioning protrusions 325 are used to cooperate with the female head positioning guide grooves 320.

[0058] Therefore, the assembly logic of the female connector fixing base 32 is basically the same as that of the male connector fixing base 22, which makes it easy for the male connector 2 and the female connector 3 to adopt similar structural ideas to achieve internal assembly.

[0059] The male connector fixing base 22 is provided with multiple male connector clamping springs 226, which together form a male connector fixing groove 222 for clamping and fixing the first connector 24. The female connector fixing base 32 is provided with multiple female connector clamping springs 326, which together form a female connector fixing groove 322 for clamping and fixing the second connector 34.

[0060] This fixing method, formed by the clamping spring, allows the first contact piece 24 and the second contact piece 34 to obtain elastic clamping force in their respective contact fixing grooves, thereby reducing the risk of contact piece loosening and displacement. Especially when the contact piece is connected to a flexible connector, the clamping spring structure helps to maintain the stability of the contact piece position and improves the reliability of the connection.

[0061] Both the male connector 2 and the female connector 3 have mounting portions 26 and 36 near the mounting panel 1, which are in contact with one side of the mounting panel 1. The first fixing element 13 and the second fixing element 14 are used to fix the mounting portion 26 of the male connector 2 and the mounting portion 36 of the female connector 3 onto the mounting panel 1, respectively.

[0062] The mounting portion 26 of the male connector 2 includes a male mounting platform 261, with male mounting posts 262 on both sides of the male mounting platform 261, and male mounting holes 263 on the male mounting posts 262. The mounting portion 36 of the female connector 3 includes a female mounting platform 361, with female mounting posts 362 on both sides of the female mounting platform 361, and female mounting holes 363 on the female mounting posts 362. The first fixing element 13 and the second fixing element 14 are screws, which are respectively connected to the male mounting holes 263 and the female mounting holes 363 to fix the male mounting platform 261 and the female mounting platform 361 to the mounting panel 1.

[0063] This installation method has advantages such as stable installation, clear force distribution, and convenient assembly and disassembly. By fitting the installation platform against the installation panel and then using the mounting posts and mounting holes on both sides for screw tightening, the male connector 2 and the female connector 3 can be reliably fixed on the installation panel 1.

[0064] The power connection panel 4 is used to fix the first power connection piece 24 and the second power connection piece 34. The power connection panel 4 can be set on the side of the mounting panel 1 away from the plug side, or it can be set in the area at the rear of the male connector 2 and the female connector 3. The specific fixing method can be set according to the actual layout, as long as it can fix or support the first power connection piece 24 and the second power connection piece 34.

[0065] The installation of the power connection panel 4 allows the power connection structures at the rear ends of multiple connectors to be supported on the same component, avoiding problems such as loosening, deformation, or messy arrangement caused by the dispersed and suspended arrangement of the rear conductive plates. For photovoltaic systems that require multi-interface integration, the power connection panel 4 also helps to improve the organization and installation reliability of the rear wiring area.

[0066] During assembly, the internal structures of the male connector 2 and the female connector 3 can be assembled separately.

[0067] For the male connector 2, firstly, the male connector terminal 23 is installed into the male connector fixing part 212, so that the male connector wiring part 231 extends toward the male connector wiring cavity 221 and the male connector plug end 232 extends toward the male connector plug cavity 213; then, the first connector piece 24 is fixed in the male connector fixing groove 222, and the first connector piece 24 is connected to the male connector wiring part 231 through the male connector flexible connector 25; then, the male connector wiring fixing seat 22 is inserted into the male connector fixing connection cavity 211, and the directional positioning is achieved by the male connector positioning guide strip 217, the male connector positioning guide groove 219, the male connector positioning plane 223 and the male connector positioning protrusion 225, and is fixed by the male connector fixing buckle 224 and the male connector fixing groove 218.

[0068] The assembly process of the female connector 3 is similar, that is, first install the female connector terminal 33, then install the second connector piece 34 and connect it through the female connector flexible connector 35, and finally insert the female connector fixing base 32 into the female connector fixing cavity 311 and fix it through the corresponding positioning and snap-fit ​​structure.

[0069] After the male connector 2 and female connector 3 are internally assembled, the male connector 2 is inserted into the first through slot 11 of the mounting panel 1, so that the male mounting platform 261 rests against the surface of the mounting panel 1, and is fixed by the first fixing element 13 engaging with the male mounting hole 263. The female connector 3 is inserted into the second through slot 12 of the mounting panel 1, so that the female mounting platform 361 rests against the surface of the mounting panel 1, and is fixed by the second fixing element 14 engaging with the female mounting hole 363. Then, the power receiving panel 4 is positioned at the rear end, and the first power receiving piece 24 and the second power receiving piece 34 are fixed, thus completing the assembly of the entire photovoltaic connector assembly.

[0070] During use, the male connector 2 and the female connector 3 can be plugged into corresponding external connectors, or serve as male-female mating interfaces within the assembly. When the male connector 2 and the female connector 3 are plugged in, the plug-in latch 315 enters the plug-in slot 214 and forms a limit at the through slot 215 position. The sealing part 316 forms a sealing fit with the sealing groove 216 or 317, thereby completing a reliable plugging.

[0071] In the conductive path, external current can be transmitted through the first contact piece 24 to the male contact terminal 23 via the male flexible connector 25, and then conduction with the mating connector through the male plug end 232; similarly, the female connector 3 can form a conductive path through the second contact piece 34, the female flexible connector 35, the female contact terminal 33, and the female plug end 332. The flexible connector can play a buffering and flexible transition role throughout the process, improving the conductivity stability during long-term use.

[0072] In summary, this invention achieves integrated installation of photovoltaic connector assemblies through the structural cooperation between mounting panel 1, at least one male connector 2, at least one female connector 3, and power connection panel 4. Simultaneously, through the flexible conductive structure, guiding snap-fit ​​structure, plug-in locking structure, and sealing fit structure within the male connector 2 and female connector 3, the entire assembly possesses both good installation stability and excellent conductivity reliability and environmental adaptability, meeting the usage requirements of connector assemblies in photovoltaic application scenarios.

[0073] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
