[0006] In one possible implementation, the inner wall of the connecting slot is provided with a first limiting step; the outer wall of the connecting plug has a limiting wall for forming the limiting groove, the limiting wall protruding outward along the radial direction of the connecting plug; when the connecting plug is inserted into the connecting slot, the limiting wall can abut against the first limiting step along the axial direction of the connecting plug.

[0007] In one possible implementation, the first body is further provided with a first slot; the second body is further provided with a first buckle, the first buckle being used to engage and fix with the first slot when the connector plug is inserted into the connector slot.

[0008] In one possible implementation, the first connection end further includes a first encapsulation portion, in which at least a portion of the first body is encapsulated; the second connection end further includes a second encapsulation portion, in which at least a portion of the second body is encapsulated; the first encapsulation portion and the second encapsulation portion have the same structure.

[0009] In one possible implementation, the connecting slot is provided with a resilient mounting portion, and the resilient mounting portion is provided with a second limiting step; the first conductive member is provided with a first limiting protrusion that surrounds its own circumference, and the first limiting protrusion and the second limiting step abut against each other along the axial direction of the first body to restrict the first conductive member from moving in the direction of disengaging from the connecting slot along the axial direction of the first body.

[0010] In one possible implementation, the first body is further provided with a first mounting hole, which communicates with the connecting slot and the outside along the axial direction of the first body; a limiting end face is provided on the inner wall of the first mounting hole near the connecting slot along the axial direction of the first body; the first conductive element is provided with a second limiting protrusion that surrounds itself in its circumference, and the second limiting protrusion abuts against the limiting end face along the axial direction of the first body to restrict the first conductive element from moving toward the interior of the connecting slot along the axial direction of the first body.

[0011] In one possible implementation, the second connection end further includes a retaining ring, which is mounted on the second body; the connector is provided with a mounting groove, and at least a portion of the second conductive element is located within the mounting groove; one of the retaining ring and the second conductive element is provided with a third limiting step, and the other is provided with a third limiting protrusion, the third limiting protrusion and the third limiting step abutting against each other along the axial direction of the second body to restrict the second conductive element from moving along the axial direction of the second body in the direction of disengagement from the mounting groove.

Furthermore, by providing a sealing ring, the friction between the connector slot and the connector plug is increased, reducing the risk of the connector plug dislodging from the connector slot, thus improving the connection reliability between the first and second connector ends. Sealing ribs on the sealing ring are used for an interference fit with the side wall of the connector slot, further enhancing the sealing and waterproof effect of the sealing ring. At least two sealing ribs can be spaced apart along the axial direction of the connector plug. If one sealing rib deforms and fails, the remaining sealing ribs can still ensure the sealing effect of the sealing ring, improving its reliability and service life, and thus enhancing the waterproof reliability of the photovoltaic connector. Moreover, when adjacent sealing ribs are spaced apart, a gap is formed between adjacent sealing ribs. This gap provides space for the deformation of the sealing ribs, allowing them to deform more easily. This enables the sealing ribs to adhere tightly to the connector slot under their own restoring force, further improving the sealing and waterproof effect of the sealing ring, making the photovoltaic connector provided in this application suitable for marine photovoltaic environments.

[0071] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0072] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0073] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0074] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0075] This application provides a photovoltaic connector, which is installed on a photovoltaic module to achieve electrical connection between two adjacent photovoltaic modules, or to achieve electrical connection between an inverter and a photovoltaic module in a photovoltaic system. Figure 1 and Figure 2 As shown, the photovoltaic connector includes a first connecting end 10 and a second connecting end 20. One of the first connecting end 10 and the second connecting end 20 is a positive connecting end, and the other is a negative connecting end. The first connecting end 10 is electrically connected to a first junction box on the photovoltaic module via a first cable 30, and the second connecting end 20 is electrically connected to a second junction box on the photovoltaic module via a second cable 40. This application embodiment uses the photovoltaic connector to achieve electrical connection between two adjacent photovoltaic modules as an example. In two adjacent photovoltaic modules, the first connecting end 10 of one and the second connecting end 20 of the other can be electrically connected through a plug-in fit, thereby achieving electrical connection between the two photovoltaic modules.

[0076] Specifically, such as Figure 2 and Figure 3 As shown, the first connecting end 10 includes a first body 1 and a first conductive element 2 mounted on the first body 1. The first body 1 is provided with a connecting slot 11, and at least a portion of the first conductive element 2 is located within the connecting slot 11. The second connecting end 20 includes a second body 3 and a second conductive element 4 mounted on the second body 3. The second body 3 is provided with a connecting plug 31, and at least a portion of the second conductive element 4 is located within the connecting plug 31. When the connecting plug 31 is inserted into the connecting slot 11, an electrical connection can be formed between the first conductive element 2 and the second conductive element 4, thereby realizing the electrical connection between the first connecting end 10 and the second connecting end 20.

[0077] Combination Figure 4 and Figure 5 As shown, the photovoltaic connector also includes a sealing ring 5, which is fitted onto the connector plug 31. The sealing ring 5 seals against the side wall of the connector slot 11 when the connector plug 31 is inserted into the connector slot 11, thereby achieving a sealing and waterproof effect between the first connecting end 10 and the second connecting end 20. Furthermore, by providing the sealing ring 5, the friction between the connector slot 11 and the connector plug 31 is increased, reducing the risk of the connector plug 31 dislodging from the connector slot 11, thus improving the connection reliability between the first connecting end 10 and the second connecting end 20.

[0078] Furthermore, the sealing ring 5 includes sealing ribs 51 extending circumferentially along the connector plug 31. The sealing ribs 51 are used for an interference fit with the sidewall of the connector slot 11, which helps improve the sealing and waterproofing effect of the sealing ring 5. At least two sealing ribs 51 can be provided at Z-intervals along the axial direction of the connector plug 31. If one sealing rib 51 deforms and fails, the remaining sealing ribs 51 can still ensure the sealing effect of the sealing ring 5, which helps improve the reliability and service life of the sealing ring 5, thereby improving the waterproof reliability of the photovoltaic connector. Moreover, as... Figure 5 As shown, when adjacent sealing ribs 51 are spaced apart, a gap 52 is formed between two adjacent sealing ribs 51. The gap 52 provides a certain space for the deformation of the sealing ribs 51, thereby facilitating larger deformation of the sealing ribs 51. This allows the sealing ribs 51 to fit tightly against the connecting slot 11 under the action of their own restoring force, which is beneficial to further improve the sealing and waterproofing effect of the sealing ring 5, so that the photovoltaic connector provided in this embodiment can be used in marine photovoltaic environments. The number of sealing ribs 51 can be 2, 3, 4 or more, and this embodiment does not limit this.

[0079] The electrical connection structure between the first conductive element 2 and the second conductive element 4 provided in this embodiment is as follows: Figure 2 As shown, the second conductive element 4 is provided with a conductive slot 42, and a barb structure is provided on the side wall of the conductive slot 42. When the connector 31 is plugged into the connector slot 11, at least a part of the first conductive element 2 can extend into the connector 31 and be plugged into the conductive slot 42. At this time, the barb structure can pierce the second conductive element 2, thereby realizing the electrical connection between the first conductive element 2 and the second conductive element 4.

[0080] In one specific implementation, such as Figure 5As shown, a limiting groove 311 is provided on the outer wall of the connector 31. The limiting groove 311 is arranged around the circumference of the connector 31. The sealing ring 5 is installed in the limiting groove 311. The limiting groove 311 is used to restrict the axial Z-movement of the sealing ring 5 along the connector 31, thereby improving the installation stability of the sealing ring 5 and ensuring that the sealing ring 5 forms a reliable sealing and waterproof effect between the first connecting end 10 and the second connecting end 20. Further, as Figure 4 and Figure 5 As shown, the outer wall of the connector 31 has a limiting wall 312 that protrudes outward along the radial direction X of the connector 31. The limiting wall 312 is used to form a limiting groove 311. Compared with the method of directly cutting out a part of the connector 31 to form the limiting groove 311, the method of forming the limiting groove 311 by setting the limiting wall 312 will not damage the structure of the connector 31 and can ensure that the structural strength of the connector 31 is not affected.

[0081] In addition, such as Figure 5 As shown, the inner wall of the connection slot 11 is also provided with a first limiting step 111. When the connector 31 is inserted into the connection slot 11, the limiting wall 312 can abut against the first limiting step 111 along the axial direction Z of the connector 31 to limit the movement of the connector 31 in its own axial direction Z, so as to avoid the connector 31 being inserted into the connection slot 11 too deeply, thereby reducing the bending or damage between the first conductive element 2 and the second conductive element 4 due to external force, which is beneficial to extending the service life of the photovoltaic connector.

[0082] In one specific implementation, such as Figure 2 and Figure 3 As shown, the first body 1 is also provided with a first slot 12, and the second body 3 is also provided with a first buckle 32. The first buckle 32 is used to engage and fix with the first slot 12 when the connector plug 31 is inserted into the connector slot 11, thereby achieving the anti-detachment effect between the first connector end 10 and the second connector end 20. When the photovoltaic connector is shaken or subjected to external impact, the first connector end 10 and the second connector end 20 will not easily come loose, which helps to improve the reliability and stability of the connection between the first connector end 10 and the second connector end 20.

[0083] Specifically, in combination Figure 4As shown, the first latch 32 is an elastic structure and is provided with a sliding inclined surface 321 and a latch 322. The first slot 12 is provided with a sliding engagement portion 121 and a latching portion 122. The cross-sectional dimension of the sliding engagement portion 121 is smaller than that of the latching portion 122. During the process of inserting the connector 31 into the connector slot 11, the first latch 32 is also inserted into the first slot 12, and the sliding inclined surface 321 can form a sliding engagement with the side wall of the sliding engagement portion 121. During this process, the first latch 32 can deform inward along the radial direction X of the connector 31 under the action of the side wall of the sliding engagement portion 121 until the first latch 32 extends into the latching portion 122. Since the cross-sectional dimension of the latching portion 122 is larger, it will not squeeze the first latch 32, so the first latch 32 can be reset under the action of its own restoring force. At this time, the first latch 32 can form a latching fixation with the latching portion 122. When the first buckle 32 and the first slot 12 adopt the above structure, it can not only improve the anti-detachment effect between the first connecting end 10 and the second connecting end 20, but also improve the ease of assembly between the first connecting end 10 and the second connecting end 20 and improve the assembly efficiency.

[0084] It should be noted that the first connecting end 10 and the second connecting end 20 are not detachable after assembly. They can be disassembled by using a professional unlocking tool to release the first buckle 32 from the first slot 12.

[0085] The specific structures of the first connecting end 10 and the second connecting end 20 will be described in detail below. First, the specific structure of the first connecting end 10 will be described, as follows: Figure 6 As shown, the first body 1 is provided with a first mounting hole 13. Along the axial direction Z of the first body 1, the first mounting hole 13 communicates with the connecting slot 11 and the outside. At least a portion of the first conductive element 2 extends into the connecting slot 11 through the first mounting hole 13 and is fixedly connected to the connecting slot 11; the remaining portion of the first conductive element 2 is located in the first mounting hole 13 and is fixedly connected to the first cable 30 extending into the first mounting hole 13, so that the first conductive element 2 and the first cable 30 form an electrical connection.

[0086] like Figure 7As shown, the first main body 1 also has a resilient mounting portion 112 in the connecting slot 11. The resilient mounting portion 112 has a second limiting step 112a, and the first conductive member 2 has a first limiting protrusion 21 that cooperates with the second limiting step 112a. During the process of the first conductive member 2 extending into the connecting slot 11 along the first mounting hole 13, the first conductive member 2 can push the resilient mounting portion 112 outward along the radial direction X of the first main body 1 and form a sliding engagement with the resilient mounting portion 112 to avoid the resilient mounting portion 112 obstructing the installation of the first conductive member 2. When the first conductive element 2 slides to the position where the first limiting protrusion 21 is aligned with the second limiting step 112a, the pushing of the first conductive element 2 can be stopped. At this time, the first limiting protrusion 21 can abut against the second limiting step 112a along the axial direction Z of the first body 1 to restrict the first conductive element 2 from moving along the axial direction Z of the first body 1 in the direction of disengaging from the connecting slot 11, thereby reducing the risk of the first conductive element 2 falling off the first body 1 and improving the installation reliability and stability of the first conductive element 2.

[0087] The first limiting protrusion 21 can be arranged around the circumference of the first conductive element 2, which facilitates the installation of the first conductive element 2. No matter what angle the first conductive element 2 rotates along its own axis, it will not affect the first limiting protrusion 21 from affecting the second limiting step 112a to form a limiting fit.

[0088] Furthermore, two elastic mounting portions 112 can be provided within the connecting slot 11. These two elastic mounting portions 112 are symmetrically distributed along the radial direction X of the first conductive member 2, thereby limiting the first conductive member 2 in the radial direction X, reducing the risk of tilting, and further improving the installation reliability and stability of the first conductive member 2. Of course, the number of elastic mounting portions 112 can also be 3, 4, 5, or more, and they can be distributed at intervals along the circumference of the first conductive member 2; this embodiment does not impose any limitations on this.

[0089] like Figure 7 As shown, along the axial direction Z of the first body 1, a limiting end face 131 is provided at one end of the inner wall of the first mounting hole 13 near the connecting slot 11. The first conductive element 2 is provided with a second limiting protrusion 22 that surrounds itself circumferentially. The second limiting protrusion 22 and the limiting end face 131 abut against each other along the axial direction Z of the first body 1, which is used to restrict the movement of the first conductive element 2 toward the interior of the connecting slot 11 along the axial direction Z of the first body 1. This can prevent the length of the first conductive element 2 extending into the connecting slot 11 from being too long. In this embodiment, through the abutting cooperation between the first limiting protrusion 21 and the second limiting step 112a, and the abutting cooperation between the second limiting protrusion 22 and the limiting end face 131, the movement of the first conductive element 2 in the axial direction Z of the first body 1 can be completely restricted, thereby realizing the fixed connection between the first conductive element 2 and the first body 1.

[0090] Next, the specific structure of the second connection end 20 will be described, such as... Figure 2 As shown, the connector 31 is provided with a mounting groove 313 and a second mounting hole 33. Along the axial direction Z of the second body 3, the second mounting hole 33 communicates with the mounting groove 313 and the outside. At least a portion of the second conductive element 4 extends into the mounting groove 313 through the second mounting hole 33, and the first conductive element 2 can extend into the mounting groove 313 to form an electrical connection with the second conductive element 4. Figure 3 and Figure 8 As shown, the second connecting end 20 also includes a retaining ring 8, which is accommodated in the second mounting hole 33 and fixedly connected to the second body 3. One of the retaining ring 8 and the second conductive element 4 is provided with a third limiting step 81, and the other is provided with a third limiting protrusion 41. After the second conductive element 4 is installed onto the second body 3, the retaining ring 8 is then installed onto the second body 3. At this time, the third limiting protrusion 41 can abut against the third limiting step 81 along the axial direction Z of the second body 3, thereby restricting the movement of the second conductive element 4 along the axial direction Z of the second body 3 towards the direction of disengagement from the mounting groove 313. This reduces the risk of the second conductive element 4 falling off the second body 3 and improves the installation reliability and stability of the second conductive element 4.

[0091] In this embodiment, the third limiting protrusion 41 can be disposed on the outer wall of the second conductive member 4 and arranged around the second conductive member 4 in the circumferential direction. Correspondingly, the anti-reverse ring 8 can be provided with a plurality of elastic pieces 801 spaced apart in the circumferential direction. Each elastic piece 801 is provided with a third limiting step 81 to improve the limiting effect of the anti-reverse ring 8 on the second conductive member 4.

[0092] like Figure 8 As shown, the anti-reverse ring 8 is also provided with a second buckle 82, and the side wall of the second mounting hole 33 is provided with a second slot 331. The second buckle 82 can be engaged and fixed with the second slot 331 so that the anti-reverse ring 8 and the second body 3 can be fixedly connected, thereby ensuring that the anti-reverse ring 8 can play a stable limiting role on the second conductive component 4.

[0093] In the above embodiments, such as Figure 2 and Figure 3As shown, the first connecting end 10 further includes a first encapsulation part 6, in which at least a portion of the first body 1 is encapsulated. The first encapsulation part 6 can protect the connection between the first cable 30 and the first body 1, which helps to improve the structural strength of the connection between the first cable 30 and the first body 1. The second connecting end 20 further includes a second encapsulation part 7, in which at least a portion of the second body 3 is encapsulated. The second encapsulation part 7 can protect the connection between the second cable 40 and the second body 3, which helps to improve the structural strength of the connection between the second cable 40 and the second body 3. In this embodiment, both the first encapsulation part 6 and the second encapsulation part 7 are manufactured using a molding process. This process enables the first encapsulation part 6 and the second encapsulation part 7 to have good waterproof performance, thereby enabling the photovoltaic connector to achieve a double waterproof effect. Moreover, manufacturing the first encapsulation part 6 and the second encapsulation part 7 using a molding process can simplify the assembly steps of the photovoltaic connector. Compared with manufacturing the first encapsulation part 6 and the second encapsulation part 7 as separate parts and then installing them onto the first body 1 and the second body 3 respectively, it can not only improve the assembly efficiency of the photovoltaic connector, but also reduce the loss rate during the assembly process.

[0094] The first encapsulation part 6 may include a first inner encapsulation structure 61 and a first outer encapsulation structure 62 made of different materials. The first inner encapsulation structure 61 may be made of a material with higher hardness to improve the sealing and waterproofing effect of the first encapsulation part 6. The first outer encapsulation structure 62 may be made of a material with lower hardness to ensure that the first encapsulation part 6 can be bent or deformed to a certain extent, thereby improving the flexibility of the first encapsulation part 6. Similarly, the second encapsulation part 7 may include a second inner encapsulation structure 71 and a second outer encapsulation structure 72 made of different materials. The second inner encapsulation structure 71 may be made of a material with higher hardness to improve the sealing and waterproofing effect of the second encapsulation part 7. The second outer encapsulation structure 72 may be made of a material with lower hardness to ensure that the second encapsulation part 7 can be bent or deformed to a certain extent, thereby improving the flexibility of the second encapsulation part 7.

[0095] In this embodiment, the first inner packaging structure 61 and the second inner packaging structure 71 have the same structure, and the first outer packaging structure 62 and the second outer packaging structure 72 have the same structure. That is, the first inner packaging structure 61 and the second inner packaging structure 71 can be prepared using the same mold, and the first outer packaging structure 62 and the second outer packaging structure 72 can be prepared using the same mold. This helps to reduce the manufacturing cost and the difficulty of the manufacturing process of the photovoltaic connector.

[0096] In the above embodiments, such as Figure 3As shown, the first main body 1 has a first exposed portion 14, and the connecting slot 11 is disposed in the first exposed portion 14. The second main body 3 has a second exposed portion 34, and the connecting plug 31 is fixedly connected to the second exposed portion 34. The first exposed portion 14 and the second exposed portion 34 have a flat structure, which makes the photovoltaic connector lighter and thinner overall, occupies less space, and is easier to store.

[0097] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
