Description

Technical Field

[0001] This application relates to the field of photovoltaic module technology, and in particular to a photovoltaic connector. Background Technology

[0002] Photovoltaic connectors are used to connect photovoltaic modules to inverters, cables, or other photovoltaic components to ensure the safety of current transmission. A photovoltaic connector mainly includes a positive connector and a negative connector. The ends of the positive and negative connectors that are close to each other are connected together, while the ends that are far apart can be connected to different printed circuit boards via conductive components to achieve circuit continuity and ensure stable current transmission.

[0003] During the installation of photovoltaic connectors, stress issues may arise between the conductive parts of the photovoltaic connector and the printed circuit board due to the influence of the angle and force applied during installation. This reduces the stability and reliability of the connection between the two, potentially leading to poor current transmission performance between the photovoltaic connector and the printed circuit board.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] Embodiments of this application provide a photovoltaic connector, such as... Figure 1 As shown, the photovoltaic connector includes a socket connector 1 and a plug connector 2, which are distributed relative to each other along the length of the photovoltaic connector.

[0090] like Figure 2 , Figure 3 and Figure 4As shown, the socket connector 1 is provided with a pin terminal 13 and a first conductive element 14, and the plug connector 2 is provided with a socket terminal 23 and a second conductive element 24. One end of the pin terminal 13 is engaged with one end of the socket terminal 23, and the other end of the pin terminal 13 and the other end of the socket terminal 23 are electrically connected to different printed circuit boards (not shown in the figure) through the first conductive element 14 and the second conductive element 24, respectively.

[0091] like Figure 6 , Figure 7 and Figure 8 As shown, the pin terminal 13 includes an integrally formed pin 131 and a first mating part 132, and the sleeve terminal 23 includes an integrally formed sleeve 231 and a second mating part 232. The pin 131 and the sleeve 231 are engaged. Both the first mating part 132 and the second mating part 232 are provided with elastic contact areas. The elastic contact area of ​​the first mating part 132 is used to elastically connect with the first conductive element 14, and the elastic contact area of ​​the second mating part 232 is used to elastically connect with the second conductive element 24.

[0092] In this embodiment, the pin terminal 13 and the socket terminal 23 are respectively disposed inside the socket connector 1 and the plug connector 2. When the socket connector 1 and the plug connector 2 are connected, one end of the pin terminal 13 and one end of the socket terminal 23 are engaged to connect the circuit between the socket connector 1 and the plug connector 2. The engagement improves the stability of the contact and the reliability of the conductivity between the pin terminal 13 and the socket terminal 23, thereby enabling the photovoltaic connector to have good working performance.

[0093] Specifically, the pin terminal 13 includes an integrally formed pin 131 and a first mating portion 132, and the socket terminal 23 includes an integrally formed socket 231 and a second mating portion 232. The pin 131 and the socket 231 engage to achieve an electrical connection between the socket connector 1 and the plug connector 2. Both the first mating portion 132 and the second mating portion 232 are provided with elastic contact areas. The first mating portion 132 is elastically connected to the first conductive element 14 through its elastic contact area to achieve a flexible electrical connection between the pin terminal 13 and the first conductive element 14. The second mating portion 232 is elastically connected to the second conductive element 24 through its elastic contact area to achieve a flexible electrical connection between the socket terminal 23 and the second conductive element 24.

[0094] By integrating the pin 131, the first mating part 132, the sleeve 231, and the second mating part 232 into a single molded structure, the structural strength of the pin terminal 13 and the sleeve terminal 23 can be improved, reducing the possibility of failure during operation and thus extending their service life. Furthermore, the overall integrity of the pin terminal 13 and the sleeve terminal 23 can be enhanced, reducing the number of components and thus minimizing assembly steps and material input, ultimately lowering production costs.

[0095] Meanwhile, by providing elastic contact areas on the first mating part 132 and the second mating part 232, at least a portion of the first mating part 132 and the second mating part 232 can be elastically deformed.

[0096] During the installation of the socket connector 1, one end of the first conductive element 14 is elastically connected to the first mating part 132, and the other end of the first conductive element 14 is fixedly connected to the printed circuit board. Through the elastic contact area of ​​the first mating part 132, the end of the first conductive element 14 connected to the first mating part 132 can move relative to the pin terminal 13 during the installation process to adapt to the installation conditions of the socket connector 1. This avoids the risk of the connection between the pin terminal 13 and the first conductive element 14 breaking under stress during the installation process, thereby reducing the installation difficulty of the socket connector 1 and ensuring good conductivity between the socket connector 1 and the printed circuit board to meet the current transmission conditions.

[0097] During the installation of the plug connector 2, one end of the second conductive element 24 is elastically connected to the second mating part 232, and the other end of the second conductive element 24 is fixedly connected to the printed circuit board. Through the elastic contact area of ​​the second mating part 232, the end of the second conductive element 24 connected to the second mating part 232 can move relative to the socket terminal 23 during the installation process to adapt to the installation conditions of the plug connector 2. This avoids the risk of the connection between the socket terminal 23 and the second conductive element 24 breaking under stress during the installation process, thereby reducing the installation difficulty of the plug connector 2 and ensuring good conductivity between the plug connector 2 and the printed circuit board to meet the current transmission conditions.

[0098] Therefore, this embodiment not only improves the structural strength of the pin terminal 13 and the socket terminal 23 and reduces their production cost by setting the pin 131, the first mating part 132, the socket 231 and the second mating part 232 as an integrally formed structure, but also provides elastic contact areas on the first mating part 132 and the second mating part 232 so that the connection between the first conductive element 14 and the first mating part 132 and the second conductive element 24 and the second mating part 232 can adapt to the installation conditions of each connector. This reduces the installation difficulty of each connector while ensuring the conductivity between each connector and each printed circuit board, which is beneficial to improving the stability and reliability of the photovoltaic connector during operation.

[0099] In one specific implementation, such as Figure 6 and Figure 8 As shown, the first mating part 132 includes a plurality of first elastic members 132a, which are distributed at intervals along the circumference of the photovoltaic connector to form an elastic contact area of ​​the first mating part 132. Each first elastic member 132a can be elastically deformed along the radial direction of the photovoltaic connector.

[0100] In this embodiment, along the length of the photovoltaic connector, the first conductive element 14 includes a first end (not shown in the figure) and a second end (not shown in the figure) disposed opposite to each other. The first end of the first conductive element 14 is used to connect with the pin terminal 13, and the second end of the first conductive element 14 is used to connect with the printed circuit board. During the connection process between the pin terminal 13 and the first conductive element 14, the first end of the first conductive element 14 can extend into the elastic contact area of ​​the first mating part 132 and abut against each of the first elastic elements 132a.

[0101] Since multiple first elastic elements 132a are distributed at intervals along the circumference of the photovoltaic connector, the first mating part 132 and the first end of the first conductive element 14 have a large contact area, which is beneficial to improving the stability and reliability of the connection between the first mating part 132 and the first conductive element 14.

[0102] Meanwhile, since each of the first elastic elements 132a can be elastically deformed along the radial direction of the photovoltaic connector, the first end of the first conductive element 14 can squeeze the first elastic element 132a in any direction, which helps to reduce the connection difficulty between the second end of the first conductive element 14 and the printed circuit board.

[0103] Specifically, when the second end of the first conductive element 14 is not under force, each of the first elastic elements 132a abuts against the outer surface of the first conductive element 14 along the radial direction of the photovoltaic connector to clamp the first conductive element 14. When the second end of the first conductive element 14 is squeezed by an external force, the first end of the first conductive element 14 can move in the opposite direction to the direction of the force and squeeze a portion of the first elastic elements 132a on the first mating part 132, so that the first mating part 132 and the first conductive element 14 can always maintain contact.

[0104] Therefore, by setting multiple first elastic elements 132a and distributing them at intervals along the circumference of the photovoltaic connector, this embodiment can achieve a flexible electrical connection between the pin terminal 13 and the first conductive element 14, so as to meet different installation conditions of the socket connector 1 during the installation process and reduce the installation difficulty of the socket connector 1.

[0105] In one specific implementation, such as Figure 7 and Figure 8 As shown, the second mating part 232 includes a plurality of second elastic members 232a, which are distributed at intervals along the circumference of the photovoltaic connector to form an elastic contact area of ​​the second mating part 232. Each second elastic member 232a can be elastically deformed along the radial direction of the photovoltaic connector.

[0106] In this embodiment, along the length of the photovoltaic connector, the second conductive member 24 includes a third end (not shown in the figure) and a fourth end (not shown in the figure) disposed opposite to each other. The third end of the second conductive member 24 is used to connect with the socket terminal 23, and the fourth end of the second conductive member 24 is used to connect with the printed circuit board. During the connection between the socket terminal 23 and the second conductive member 24, the third end of the second conductive member 24 can extend into the elastic contact area of ​​the second mating part 232 and abut against each of the second elastic members 232a.

[0107] Since multiple second elastic elements 232a are distributed at intervals along the circumference of the photovoltaic connector, the second mating part 232 and the third end of the second conductive element 24 have a large contact area, which is beneficial to improving the stability and reliability of the connection between the second mating part 232 and the second conductive element 24.

[0108] Meanwhile, since each of the second elastic members 232a can be elastically deformed along the radial direction of the photovoltaic connector, the third end of the second conductive member 24 can squeeze the second elastic member 232a in any direction, which helps to reduce the connection difficulty between the fourth end of the second conductive member 24 and the printed circuit board.

[0109] Specifically, when the fourth end of the second conductive member 24 is not under force, each of the second elastic members 232a abuts against the outer surface of the second conductive member 24 along the radial direction of the photovoltaic connector to clamp the second conductive member 24. When the fourth end of the second conductive member 24 is squeezed by an external force, the third end of the second conductive member 24 can move in the opposite direction to the direction of the force and squeeze a portion of the second elastic members 232a on the second mating part 232, so that the second mating part 232 and the second conductive member 24 can always maintain contact.

[0110] Therefore, by setting multiple second elastic elements 232a and distributing them at intervals along the circumference of the photovoltaic connector, this embodiment can achieve a flexible electrical connection between the socket terminal 23 and the second conductive element 24, so as to meet different installation conditions of the plug connector 2 during the installation process and reduce the installation difficulty of the plug connector 2.

[0111] In one specific implementation, such as Figure 6 and Figure 8 As shown, the first mating part 132 also includes a plurality of first through holes 132b, which are distributed at intervals along the circumference of the photovoltaic connector. At least one first elastic member 132a is provided in the first through hole 132b, and at least one end of the first elastic member 132a is connected to the side wall of the first through hole 132b.

[0112] In this embodiment, by providing a plurality of first through holes 132b on the first mating part 132 and placing each first elastic member 132a in each first through hole 132b, it can be ensured that the first elastic member 132a only undergoes elastic deformation along the radial direction of the photovoltaic connector within the first through hole 132b, thereby avoiding the possibility that the first elastic member 132a may shift during the elastic deformation process, leading to a reduction in the contact effect with the first conductive member 14. This is beneficial to improving the stability and reliability of the connection between the first elastic member 132a and the first conductive member 14, and thus ensuring that the socket connector 1 can have good working performance.

[0113] In one specific implementation, such as Figure 7 and Figure 8 As shown, the second mating part 232 also includes a plurality of second through holes 232b, which are distributed at intervals along the circumference of the photovoltaic connector. At least one second elastic member 232a is provided in the second through hole 232b, and at least one end of the second elastic member 232a is connected to the side wall of the second through hole 232b.

[0114] In this embodiment, by providing a plurality of second through holes 232b on the second mating part 232 and placing each second elastic member 232a in each second through hole 232b, it can be ensured that the second elastic member 232a only undergoes elastic deformation along the radial direction of the photovoltaic connector within the second through hole 232b. This avoids the possibility that the second elastic member 232a may shift during the elastic deformation process, leading to a reduction in the contact effect with the second conductive member 24. This is beneficial to improving the stability and reliability of the connection between the second elastic member 232a and the second conductive member 24, thereby ensuring that the plug connector 2 can have good working performance.

[0115] In one specific embodiment, when one end of the first elastic member 132a is connected to the sidewall of the first through hole 132b, and / or one end of the second elastic member 232a is connected to the sidewall of the second through hole 232b, both the first elastic member 132a and the second elastic member 232a are inclined relative to the length direction of the photovoltaic connector.

[0116] In this embodiment, by connecting one end of the first elastic member 132a to the sidewall of the first through hole 132b, and / or connecting one end of the second elastic member 232a to the sidewall of the second through hole 232b, the other ends of the first elastic member 132a and the second elastic member 232a are both suspended, so that the first elastic member 132a and the second elastic member 232a are inclined relative to the length direction of the photovoltaic connector. This design allows the first elastic member 132a and the second elastic member 232a to have a larger range of elastic deformation.

[0117] Optionally, along the length of the photovoltaic connector, one end of the first elastic member 132a is connected to the sidewall of the first through hole 132b away from the pin 131, while the other end of the first elastic member 132a is not connected to the sidewall of the first through hole 132b, so that the first elastic member 132a is inclined relative to the length of the photovoltaic connector. During the connection between the pin terminal 13 and the first conductive member 14, the first conductive member 14 can lift the other end of the first elastic member 132a to cause the first elastic member 132a to undergo elastic deformation, thereby realizing a flexible electrical connection between the pin terminal 13 and the first conductive member 14. Furthermore, during the installation of the socket connector 1, the first conductive member 14 can further compress a portion of the first elastic member 132a to meet the installation conditions of the socket connector 1. In addition, in this embodiment, along the direction from the first mating part 132 toward the pin 131, the cross-sectional area of ​​the elastic contact area of ​​the first mating part 132 gradually decreases, making one end of the first elastic member 132a a free end, thereby making the range of elastic deformation of the first elastic member 132a larger, and thus making the range of the installation angle between the first conductive member 14 and the printed circuit board larger, which is beneficial to further improve the flexibility of the socket connector 1 during the installation process.

[0118] Optionally, along the length of the photovoltaic connector, one end of the second elastic member 232a is connected to the sidewall of the second through hole 232b away from the socket 231, while the other end of the second elastic member 232a is not connected to the sidewall of the second through hole 232b, so that the second elastic member 232a is inclined relative to the length of the photovoltaic connector. During the connection between the socket terminal 23 and the second conductive member 24, the second conductive member 24 can lift the other end of the second elastic member 232a to cause the second elastic member 232a to undergo elastic deformation, thereby achieving a flexible electrical connection between the socket terminal 23 and the second conductive member 24. Furthermore, during the installation of the plug connector 2, the second conductive member 24 can further compress a portion of the second elastic member 232a to meet the installation conditions of the plug connector 2. In addition, in this embodiment, along the direction from the second mating part 232 toward the socket 231, the cross-sectional area of ​​the elastic contact area of ​​the second mating part 232 gradually decreases, making one end of the second elastic member 232a a free end, thereby making the range of elastic deformation of the second elastic member 232a larger, and thus making the range of installation angle between the second conductive member 24 and the printed circuit board larger, which is beneficial to further improve the flexibility of the plug connector 2 in the installation process.

[0119] In one specific implementation, such as Figure 6 , Figure 7 and Figure 8 As shown, when the two ends of the first elastic member 132a are connected to the sidewall of the first through hole 132b, and / or the two ends of the second elastic member 232a are connected to the sidewall of the second through hole 232b, the middle region of the first elastic member 132a protrudes towards the side of the first conductive member 14, and the middle region of the second elastic member 232a protrudes towards the side of the second conductive member 24.

[0120] In this embodiment, by connecting the two ends of the first elastic member 132a to the sidewall of the first through hole 132b, and / or connecting the two ends of the second elastic member 232a to the sidewall of the second through hole 232b, the middle regions of the first elastic member 132a and the second elastic member 232a protrude toward the side of the first conductive member 14 and the second conductive member 24, respectively. This design makes the elastic deformation of the first elastic member 132a and the second elastic member 232a more stable.

[0121] Optionally, along the length of the photovoltaic connector, both ends of the first elastic member 132a are connected to the sidewalls of the first through hole 132b, and the middle region of the first elastic member 132a protrudes towards the first conductive member 14 so as to abut against the outer surface of the first conductive member 14, thereby realizing the snap-fit ​​engagement between the first mating part 132 and the first conductive member 14. During the connection process between the pin terminal 13 and the first conductive member 14, the first conductive member 14 can lift the middle region of the first elastic member 132a to cause the first elastic member 132a to undergo elastic deformation, thereby realizing a flexible electrical connection between the pin terminal 13 and the first conductive member 14. Furthermore, during the installation of the socket connector 1, the first conductive member 14 can further compress a portion of the first elastic member 132a to meet the installation conditions of the socket connector 1. In addition, in this embodiment, along the length of the photovoltaic connector, the cross-sectional area in the middle of the elastic contact area of ​​the first mating part 132 is larger than the cross-sectional area at both ends, which makes the compression effect of each first elastic member 132a on the first conductive member 14 better, which is conducive to further improving the stability and reliability of the connection between the pin terminal 13 and the first conductive member 14.

[0122] Optionally, along the length of the photovoltaic connector, both ends of the second elastic member 232a are connected to the sidewalls of the second through hole 232b, and the middle region of the second elastic member 232a protrudes towards the second conductive member 24 so as to abut against the outer surface of the second conductive member 24, thereby realizing the snap-fit ​​engagement between the second mating part 232 and the second conductive member 24. During the connection process between the socket terminal 23 and the second conductive member 24, the second conductive member 24 can lift the middle region of the second elastic member 232a to cause the second elastic member 232a to undergo elastic deformation, thereby realizing a flexible electrical connection between the socket terminal 23 and the second conductive member 24. Furthermore, during the installation of the plug connector 2, the second conductive member 24 can further compress a portion of the second elastic member 232a to meet the installation conditions of the plug connector 2. In addition, in this embodiment, along the length of the photovoltaic connector, the cross-sectional area in the middle of the elastic contact area of ​​the second mating part 232 is larger than the cross-sectional area at both ends, which makes the compression effect of each second elastic member 232a on the second conductive member 24 better, which is conducive to further improving the stability and reliability of the connection between the socket terminal 23 and the second conductive member 24.

[0123] In one specific implementation, such as Figure 6 and Figure 7 As shown, along the length of the photovoltaic connector, the cross-sectional shape of the first mating part 132 is either circular or rectangular, and / or the cross-sectional shape of the second mating part 232 is either circular or rectangular.

[0124] In this embodiment, by setting the cross-sectional shape of the first mating part 132 and the second mating part 232 to be circular or rectangular, the pin terminal 13 and the socket terminal 23 can be adapted to conductive parts of different shapes, which is beneficial to improving the compatibility of the socket connector 1 and the plug connector 2.

[0125] In one specific implementation, such as Figure 6 As shown, the pin terminal 13 also includes a first main body 133. The pin 131 and the first mating part 132 are connected through the first main body 133. The first main body 133 is provided with a plurality of first limiting parts 133a. The plurality of first limiting parts 133a are distributed at intervals along the circumference of the photovoltaic connector and along the length direction of the photovoltaic connector. One end of the first limiting part 133a is connected to the first main body 133, and the other end of the first limiting part 133a is inclined relative to the first main body 133.

[0126] In this embodiment of the application, by providing a first limiting part 133a on the outer surface of the first main body 133, the pin terminal 13 can engage with the internal structure of the socket connector 1 through the first limiting part 133a during the assembly process with the socket connector 1, thereby limiting the outward movement of the pin terminal 13 along the radial direction of the photovoltaic connector, thereby reducing the possibility of the two disengaging from each other and improving the stability and reliability of the connection between the pin terminal 13 and the socket connector 1.

[0127] The first limiting part 133a is inclined relative to the first main body part 133, so that the first limiting part 133a can be elastically deformed so as to avoid the internal structure of the socket connector 1 during the assembly of the pin terminal 13 and the socket connector 1, making the assembly process smoother. During the process of the pin terminal 13 and the socket connector 1 separating from each other, it abuts against the internal structure of the socket connector 1 to play a blocking role, so that the pin terminal 13 cannot easily separate from the socket connector 1.

[0128] Meanwhile, the pin 131, the first main body 133 and the first mating part 132 can be integrally formed to improve the overall integrity of the pin terminal 13, reduce the number of components that make up the pin terminal 13, thereby reducing the assembly steps between components and the amount of production materials required, which helps to reduce the production cost of the pin terminal 13.

[0129] In one specific implementation, such as Figure 7As shown, the socket terminal 23 also includes a second main body 233. The socket 231 and the second mating part 232 are connected through the second main body 233. The second main body 233 is provided with a plurality of second limiting parts 233a. The plurality of second limiting parts 233a are distributed at intervals along the circumference of the photovoltaic connector and along the length direction of the photovoltaic connector. One end of the second limiting part 233a is connected to the second main body 233, and the other end of the second limiting part 233a is inclined relative to the second main body 233.

[0130] In this embodiment, by providing a second limiting part 233a on the outer surface of the second main body 233, the socket terminal 23 can engage with the internal structure of the plug connector 2 through the second limiting part 233a during the assembly process with the plug connector 2, thereby limiting the outward movement of the socket terminal 23 along the radial direction of the photovoltaic connector, thereby reducing the possibility of the two disengaging from each other and improving the stability and reliability of the connection between the socket terminal 23 and the plug connector 2.

[0131] The second limiting part 233a is inclined relative to the second main body part 233, so that the second limiting part 233a can be elastically deformed so as to avoid the internal structure of the plug connector 2 during the assembly of the socket terminal 23 and the plug connector 2, making the assembly process smoother. During the process of the socket terminal 23 and the plug connector 2 separating from each other, it abuts against the internal structure of the plug connector 2 to play a blocking role, so that the socket terminal 23 cannot easily separate from the plug connector 2.

[0132] Meanwhile, the insert 231, the second main body 233, and the second mating part 232 can be integrally formed to improve the overall integrity of the insert terminal 23, reduce the number of parts that make up the insert terminal 23, thereby reducing the assembly steps between the parts and the amount of production materials required, which helps to reduce the production cost of the pin insert terminal 23.

[0133] In one specific implementation, such as Figure 2 , Figure 11 and Figure 12 As shown, the socket connector 1 also includes a first body 11 and a first cover 12. The first cover 12 is connected to the side of the first body 11 away from the plug connector 2. The first cover 12 is provided with a third through hole 121. One end of the first conductive member 14 can extend out of the third through hole 121 and connect to the first printed circuit board (not shown in the figure). There is a gap between the first conductive member 14 and the inner wall of the third through hole 121.

[0134] In this embodiment, along the length of the photovoltaic connector, the first end of the first conductive element 14 extends into the first body 11 and is connected to the pin terminal 13. The second end of the first conductive element 14 extends out of the third through hole 121 and is fixedly connected to the first printed circuit board, thereby enabling the electrical connection between the socket connector 1 and the first printed circuit board through the first conductive element 14.

[0135] At least a portion of the first conductive element 14 is located within the third through hole 121, and there is a gap between the first conductive element 14 and the inner wall of the third through hole 121. This gap serves as the movement space for the first conductive element 14, allowing the first end of the first conductive element 14 to move relative to the pin terminal 13 during installation to adapt to the installation conditions of the socket connector 1. This avoids the risk of breakage at the connection between the pin terminal 13 and the first conductive element 14 during installation, thereby reducing the installation difficulty of the socket connector 1 and ensuring good conductivity between the socket connector 1 and the first printed circuit board to meet the current transmission conditions.

[0136] In one specific implementation, such as Figure 3 , Figure 11 and Figure 12 As shown, the plug connector 2 also includes a second body 21 and a second cover 22. The second cover 22 is connected to the side of the second body 21 away from the socket connector 1. The second cover 22 is provided with a fourth through hole 221. One end of the second conductive member 24 can extend out of the fourth through hole 221 and connect to the second printed circuit board (not shown in the figure). There is a gap between the second conductive member 24 and the inner wall of the fourth through hole 221.

[0137] In this embodiment, along the length of the photovoltaic connector, the third end of the second conductive member 24 extends into the second body 21 and is connected to the socket terminal 23. The fourth end of the second conductive member 24 extends out of the fourth through hole 221 and is fixedly connected to the second printed circuit board, thereby enabling the electrical connection between the plug connector 2 and the second printed circuit board through the second conductive member 24.

[0138] At least a portion of the second conductive element 24 is located within the fourth through hole 221, and there is a gap between the second conductive element 24 and the inner wall of the fourth through hole 221. This gap serves as a space for the second conductive element 24 to move relative to the socket terminal 23 during installation, thereby adapting to the installation conditions of the plug connector 2. This avoids the risk of breakage at the connection between the socket terminal 23 and the second conductive element 24 during installation, thereby reducing the installation difficulty of the plug connector 2 and ensuring good conductivity between the plug connector 2 and the second printed circuit board to meet the current transmission requirements.

[0139] In one possible implementation, such as Figure 2 As shown, the socket connector 1 also includes a first washer 15 and a first fixing member 16. The first washer 15 is sleeved on the outside of the first body 11, and the first fixing member 16 is threadedly connected to the first body 11.

[0140] The first washer 15 provides elastic reaction force to the first fastener 16, increasing the friction between the first fastener 16 and the first body 11. This reduces the possibility of them separating due to loosening caused by vibration or other factors, thus improving the stability and reliability of the connection between the first fastener 16 and the first body 11. Simultaneously, the first fastener 16 is provided with anti-slip grooves (not shown in the figure), facilitating gripping and installation / removal by workers.

[0141] In one possible implementation, such as Figure 3 As shown, the plug connector 2 also includes a second washer 25 and a second fixing member 26. The second washer 25 is sleeved on the outside of the second body 21, and the second fixing member 26 is threadedly connected to the second body 21.

[0142] The second washer 25 provides elastic reaction force to the second fastener 26, increasing the friction between the second fastener 26 and the second body 21. This reduces the possibility of them separating due to loosening caused by vibration or other factors, thus improving the stability and reliability of the connection between the second fastener 26 and the second body 21. Simultaneously, the second fastener 26 is provided with anti-slip grooves (not shown in the figure), facilitating gripping and installation / removal by workers.

[0143] In one possible implementation, the first body 11 and the second body 21 are plugged in and plugged out.

[0144] The first body 11 has a receiving portion (not shown in the figure), in which the pin terminal 13 is installed. The second body 21 has a mating portion (not shown in the figure), in which the socket terminal 23 is installed. During the assembly of the first body 11 and the second body 21, the mating portion of the second body 21 extends into the receiving portion of the first body 11, thereby causing the pin terminal 13 to engage with the socket terminal 23.

[0145] Meanwhile, the first body 11 is also provided with a bayonet (not shown in the figure), which is located on the outer side of the receiving part along the radial direction of the photovoltaic connector. The second body 21 is also provided with a locking arm (not shown in the figure), which is located on the outer side of the mating part along the radial direction of the photovoltaic connector. During the assembly of the first body 11 and the second body 21, the bayonet and the locking arm engage with each other, improving the stability of the connection between the first body 11 and the second body 21, reducing the possibility of them disengaging during use, improving the reliability of the photovoltaic connector during use, and also facilitating the assembly or disassembly of the first body 11 and the second body 21 by the operators.

[0146] In one possible implementation, such as Figure 8 , Figure 11 and Figure 12 As shown, the inner wall of the third through hole 121 is provided with a third limiting part 121a, and the outer wall of the first conductive member 14 is provided with a first recess 141. At least a portion of the third limiting part 121a is located in the first recess 141, and there is a gap between the third limiting part 121a and the inner wall of the first recess 141. The third limiting part 121a is used to restrict the movement of the first conductive member 14 along the length direction of the photovoltaic connector.

[0147] In this embodiment of the application, after the first conductive element 14 is assembled with the first body 11, at least a portion of the first conductive element 14 is located in the third through hole 121, and at least a portion of the third limiting portion 121a is located in the first recess 141.

[0148] When the first conductive element 14 is assembled with the first body 11, a gap exists between the third limiting part 121a and the side wall of the first recess 141. Specifically, when the first conductive element 14 moves along the length direction of the photovoltaic connector, the third limiting part 121a can abut against the side wall of the first recess 141, thereby restricting the movement of the first conductive element 14 along this direction. This reduces the possibility of the first conductive element 14 separating from the pin terminal 13, which helps to improve the stability and reliability of the connection between the two, and thus improves the structural stability of the socket connector 1.

[0149] Meanwhile, there is a gap between the third limiting part 121a and the bottom wall of the first recessed part 141. When the first conductive member 14 is connected to the first printed circuit board, this gap can serve as the moving space for the first conductive member 14 to achieve a flexible connection between the first conductive member 14 and the pin terminal 13, so as to adapt to the installation conditions of the socket connector 1 and avoid the risk of the connection between the two breaking under stress during installation.

[0150] In one possible implementation, such as Figure 8 , Figure 11 and Figure 12As shown, the inner wall of the fourth through hole 221 is provided with a fourth limiting part 221a, and the outer wall of the second conductive member 24 is provided with a second recess 241. At least a portion of the fourth limiting part 221a is located in the second recess 241, and there is a gap between the fourth limiting part 221a and the inner wall of the second recess 241. The fourth limiting part 221a is used to restrict the movement of the second conductive member 24 along the length direction of the photovoltaic connector.

[0151] In this embodiment of the application, after the second conductive element 24 and the second body 21 are assembled, at least a portion of the second conductive element 24 is located in the fourth through hole 221, and at least a portion of the fourth limiting portion 221a is located in the second recess 241.

[0152] When the second conductive member 24 is assembled with the second body 21, a gap exists between the fourth limiting portion 221a and the side wall of the second recess 241. Specifically, when the second conductive member 24 moves along the length direction of the photovoltaic connector, the fourth limiting portion 221a can abut against the side wall of the second recess 241, thereby restricting the movement of the second conductive member 24 in that direction. This reduces the possibility of the second conductive member 24 separating from the socket terminal 23, which helps to improve the stability and reliability of the connection between the two, and thus improves the structural stability of the plug connector 2.

[0153] Meanwhile, there is a gap between the fourth limiting part 221a and the bottom wall of the second recess 241. When the second conductive member 24 is connected to the second printed circuit board, this gap can serve as a space for the second conductive member 24 to move, so as to realize a flexible connection between the second conductive member 24 and the socket terminal 23, so as to adapt to the installation conditions of the plug connector 2 and avoid the risk of the connection between the two breaking under stress during installation.

[0154] In one specific implementation, such as Figure 5 , Figure 9 , Figure 11 and Figure 12 As shown, the first body 11 has a first protrusion 111 on the side facing the first cover 12, and the first cover 12 has a fifth through hole 122. The first protrusion 111 and the fifth through hole 122 are connected in a fitting manner. The inner wall of the fifth through hole 122 has a fifth limiting part 122a. At least a portion of the first protrusion 111 is located on the side of the fifth limiting part 122a away from the first body 11, and there is a gap between the first protrusion 111 and the fifth limiting part 122a.

[0155] The first protrusion 111 is capable of elastic deformation.

[0156] In this embodiment of the application, after the first body 11 and the first cover 12 are assembled, at least a portion of the first protrusion 111 is located in the fifth through hole 122, and along the length direction of the photovoltaic connector, the end of the first protrusion 111 is located on the side of the fifth limiting part 122a away from the first body 11.

[0157] There is a gap between the end of the first protrusion 111 and the fifth limiting part 122a. Specifically, when the first cover 12 moves in a direction away from the first body 11, the end of the first protrusion 111 can abut against the fifth limiting part 122a, thereby restricting the movement of the first cover 12 in that direction, reducing the possibility of the first cover 12 separating from the first body 11, which helps to improve the stability and reliability of the connection between the two, and thus improves the structural stability of the socket connector 1.

[0158] Meanwhile, the elastic deformation of the first protrusion 111 helps improve the assembly efficiency between the first body 11 and the first cover 12. Specifically, the end of the first protrusion 111 may be provided with a guide surface to further improve assembly efficiency.

[0159] Additionally, along the length of the photovoltaic connector, the first protrusion 111 may be provided with a V-shaped notch to enable the first protrusion 111 to have the ability to elastically deform. Specifically, during the assembly of the first cover 12 and the first body 11, the fifth limiting part 122a presses the end of the first protrusion 111 and causes it to retract inward so that the end of the first protrusion 111 can extend into the fifth through hole 122. After the fifth limiting part 122a releases the pressure on the end of the first protrusion 111, the end of the first protrusion 111 expands outward to achieve a snap-fit ​​engagement between the first protrusion 111 and the fifth through hole 122.

[0160] In one specific implementation, such as Figure 5 , Figure 10 , Figure 11 and Figure 12 As shown, the second body 21 has a second protrusion 211 on the side facing the second cover 22, and the second cover 22 has a sixth through hole 222. The second protrusion 211 and the sixth through hole 222 are connected in a fitting manner. The inner wall of the sixth through hole 222 has a sixth limiting part 222a. At least a portion of the second protrusion 211 is located on the side of the sixth limiting part 222a away from the second body 21, and there is a gap between the second protrusion 211 and the sixth limiting part 222a.

[0161] The second protrusion 211 is capable of elastic deformation.

[0162] In this embodiment of the application, after the second body 21 and the second cover 22 are assembled, at least a portion of the second protrusion 211 is located in the sixth through hole 222, and along the length direction of the photovoltaic connector, the end of the second protrusion 211 is located on the side of the sixth limiting part 222a away from the second body 21.

[0163] There is a gap between the end of the second protrusion 211 and the sixth limiting part 222a. Specifically, when the second cover 22 moves in a direction away from the second body 21, the end of the second protrusion 211 can abut against the sixth limiting part 222a, thereby restricting the movement of the second cover 22 in that direction, reducing the possibility of the second cover 22 separating from the second body 21, which helps to improve the stability and reliability of the connection between the two, and thus improves the structural stability of the plug connector 2.

[0164] Meanwhile, the second protrusion 211, being elastically deformable, helps improve the assembly efficiency between the second body 21 and the second cover 22. Specifically, the end of the second protrusion 211 may be provided with a guide surface to further improve assembly efficiency.

[0165] Additionally, along the length of the photovoltaic connector, the second protrusion 211 may be provided with a V-shaped notch to enable the second protrusion 211 to have the ability to elastically deform. Specifically, during the assembly of the second cover 22 and the second body 21, the sixth limiting part 222a presses the end of the second protrusion 211 and causes it to retract inward so that the end of the second protrusion 211 can extend into the sixth through hole 222. After the sixth limiting part 222a releases the pressure on the end of the second protrusion 211, the end of the second protrusion 211 expands outward to achieve a snap-fit ​​engagement between the second protrusion 211 and the sixth through hole 222.

[0166] In one specific implementation, such as Figure 9 , Figure 11 and Figure 12 As shown, one of the first body 11 and the first cover 12 is provided with a third protrusion 112, and the other is provided with a third recess 123. The third protrusion 112 and the third recess 123 are connected in a cooperative manner. The third protrusion 112 is used to restrict the movement of the first cover 12 relative to the first body 11 along the circumferential direction of the photovoltaic connector.

[0167] In this embodiment, along the length of the photovoltaic connector, a third protrusion 112 is provided on the side of the first body 11 facing the first cover 12, and a third recess 123 is provided on the side of the first cover 12 facing the first body 11. During the assembly of the first body 11 and the first cover 12, the third protrusion 112 and the third recess 123 cooperate to restrict the movement of the first cover 12 relative to the first body 11 along the circumferential direction of the photovoltaic connector, which is beneficial to further improve the structural stability of the socket connector 1.

[0168] In one possible implementation, the first body 11 is provided with a plurality of third protrusions 112 spaced apart along the circumference of the photovoltaic connector, and the first cover 12 is provided with a plurality of third recesses 123 spaced apart along the circumference of the photovoltaic connector, with each third protrusion 112 correspondingly connected to each third recess 123.

[0169] In one possible implementation, the first body 11 and the first cover 12 can also be fixedly connected by means of adhesive bonding, which further reduces the risk of them separating from each other and improves the structural stability of the socket connector 1.

[0170] In one possible implementation, the end of the third protrusion 112 may be provided with a guide surface to further improve assembly efficiency.

[0171] In one specific implementation, such as Figure 10 , Figure 11 and Figure 12 As shown, one of the second body 21 and the second cover 22 is provided with a fourth protrusion 212, and the other is provided with a fourth recess 223. The fourth protrusion 212 and the fourth recess 223 are connected in a cooperative manner. The fourth protrusion 212 is used to restrict the movement of the second cover 22 relative to the second body 21 along the circumferential direction of the photovoltaic connector.

[0172] In this embodiment, along the length of the photovoltaic connector, the second body 21 has a fourth protrusion 212 on the side facing the second cover 22, and the second cover 22 has a fourth recess 223 on the side facing the second body 21. During the assembly of the second body 21 and the second cover 22, the fourth protrusion 212 and the fourth recess 223 cooperate to restrict the movement of the second cover 22 relative to the second body 21 along the circumferential direction of the photovoltaic connector, which helps to further improve the structural stability of the plug connector 2.

[0173] In one possible implementation, the second body 21 is provided with a plurality of fourth protrusions 212 spaced apart along the circumference of the photovoltaic connector, and the second cover 22 is provided with a plurality of fourth recesses 223 spaced apart along the circumference of the photovoltaic connector, with each fourth protrusion 212 correspondingly connected to each fourth recess 223.

[0174] In one possible implementation, the second body 21 and the second cover 22 can also be fixedly connected by means of adhesive bonding, which further reduces the risk of them detaching from each other and improves the structural stability of the plug connector 2.

[0175] In one possible implementation, the end of the fourth protrusion 212 may be provided with a guide surface to further improve assembly efficiency.
