[0040] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0041] The inventors found in their research that the assembly of photovoltaic connectors is relatively difficult, including the difficulty in aligning the connecting nuts, low assembly efficiency, and low production efficiency.

[0042] Therefore, how to overcome the above problems has become one of the technical problems that need to be solved urgently at this stage.

[0043] In view of this, the utility model provides a photovoltaic connector and a junction box, and improves the production efficiency by improving the connecting nut of the photovoltaic connector.

[0044] The following is a detailed description with reference to the accompanying drawings and specific embodiments.

[0045] Figure 1 FIG. 1 is a schematic diagram of a connecting nut provided in an embodiment of the present application. Figure 2 FIG. 1 is a plan view of a positioning groove provided in an embodiment of the present application. Please refer to FIG. Figure 1 and Figure 2 The present application provides a photovoltaic connector, including a connecting nut 10, the connecting nut 10 includes an inner wall 12 and an outer wall 11, the inner wall 12 and the outer wall 11 are in a concentric ring shape, and the connecting nut 10 also includes a first end face 01 and a second end face 02 arranged opposite to each other along a first direction D1, and the first direction D1 is a height direction of the connecting nut 10;

[0046] The connecting nut 10 includes a positioning groove 13, which is recessed from the outer wall 11 to the inner wall 12 and does not pass through the inner wall 12; the positioning groove 13 is recessed from the first end surface 01 to the second end surface 02 along the first direction D1;

[0047] The positioning groove 13 includes a limiting groove 131 and a guiding groove 132 which are connected to each other. Along the first direction D1, the guiding groove 132 is located on a side of the limiting groove 131 away from the plane where the second end surface 02 is located, and the side walls of the guiding groove 132 are all chamfered surfaces.

[0048] It should be noted that the drawings in this application are for clear illustration only and do not represent actual sizes and actual structures.

[0049] Specifically, the present application provides a photovoltaic connector, including a connecting nut 10, which is used to fix the panel of the photovoltaic connector. The installation efficiency of the connecting nut 10 directly affects the production efficiency. The connecting nut 10 in the photovoltaic connector provided by the present application is annular, including an outer wall 11 and an inner wall 12. Along a first direction D1, the connecting nut 10 includes a first end face 01 and a second end face 02 that are relatively arranged. The connecting nut 10 includes a positioning groove 13, which is recessed from the outer wall 11 to the inner wall 12, and is perpendicular to the outer wall 11. The inner wall 12 does not penetrate the connecting nut 10; the positioning groove 13 is recessed from the first end face 01 to the second end face 02, and does not penetrate the connecting nut 10 along the first direction D1, that is, a positioning groove 13 with an appearance similar to a "U" shape is formed on the outer wall 11 of the connecting nut 10. With such a configuration, when the connecting nut 10 is installed or removed by tools, the positioning groove 13 and the inner wall 12 of the connecting nut 10 both have a certain limiting effect, which is beneficial to prevent the tool and the connecting nut from being offset, thereby saving assembly time and further improving production efficiency.

[0050] The positioning groove 13 includes a limiting groove 131 and a guide groove 132 which are interconnected. Along the first direction D1, the guide groove 132 is located on the side of the limiting groove 131 away from the plane where the second end face 02 is located, that is, along the first direction D1, the limiting groove 131 is located on the side of the guide groove 132 away from the plane where the first end face 01 is located. The positioning groove 13 is recessed from the first end face 01 to the second end face 02, therefore, the guide groove 132 is located at the entrance of the positioning groove 13. The side walls of the guide groove 132 in the present application are all chamfered surfaces, that is, in the guide groove 132, the three side walls of the guide groove 132 are all chamfered. With such a configuration, when a tool is used to install the connecting nut 10, the guide groove 132 has a certain guiding effect, which is conducive to the tool smoothly entering the limiting groove 131 from the guide groove 132, and the tool is limited by the limiting groove 131. The present application is conducive to blind tightening of the connecting nut by setting the guide groove 132 and the limiting groove 131, thereby saving assembly time and further improving production efficiency.

[0051] It should be noted that the positioning groove 13 of the present application is actually a female groove formed on the outer wall 11 of the connecting nut 10 along the first direction D1 from the first end face 01 to the second end face 02, and along the outer wall 11 in a direction perpendicular to the inner wall 12, and then the edge of the female groove close to the first end face 01 is chamfered to form a limit groove 131 and a guide groove 132. Therefore, the side walls of the guide groove 132 are all chamfered surfaces. The setting of the guide groove 132 is conducive to the installation tool entering the positioning groove 13, thereby reducing the difficulty of alignment and facilitating the alignment of the installation tool with the positioning groove 13.

[0052] It can be understood that the guide groove 132 is a groove formed by chamfering, and therefore, the height of the limiting groove 131 along the first direction D1 is greater than the height of the guide groove 132 along the first direction D1.

[0053] Figure 3 FIG. 1 is a schematic diagram of a positive electrode connector provided in an embodiment of the present application. Figure 4 FIG. 1 is a schematic diagram of a negative electrode connector provided in an embodiment of the present application. Please refer to FIG.

The positive connector 101 includes a connecting nut 10, which is sleeved on the periphery of the positive connector 101; the negative connector 102 also includes a connecting nut 10, which is sleeved on the periphery of the negative connector 102; the connecting nut 10 used in the photovoltaic connector provided by the present application, the positioning groove 13 and the inner wall 12 of the connecting nut 10 have a certain limiting effect, which is conducive to preventing the connection nut from being offset from the installation tool. This helps save assembly time and thus helps improve production efficiency; at the same time, the side walls of the guide groove 132 in the positioning groove 13 are all chamfered surfaces. When a tool is used to install the connecting nut 10, the guide groove 132 has a certain guiding effect, which helps the installation tool to smoothly enter the limiting groove 131 from the guide groove 132, and the installation tool is limited by the limiting groove 131. The present application facilitates blind screwing of the connecting nut 10 by setting the guide groove 132 and the limiting groove 131, which helps save assembly time and thus helps improve production efficiency.

[0055] It should be noted that when the connecting nut 10 is installed or removed, a tool is generally used for installation or removal.

When the unlocking tool 20 is used to install or remove the connecting nut 10, the connecting nut 10 includes a guide groove 132 and a limiting groove 131. The guide groove 132 has a certain guiding effect, which is conducive to the protrusion 21 of the unlocking tool 20 to smoothly enter the limiting groove 131, and the protrusion 21 of the unlocking tool 20 is limited by the limiting groove 131. The present application is conducive to blind screwing by setting the guide groove 132 and the limiting groove 131, thereby saving assembly time and further improving production efficiency.

[0057] Please refer to Figure 1 , Figure 3 and Figure 4 In an optional embodiment of the present application, the inner wall 12 of the connecting nut 10 includes an internal thread 14, the nut installation position corresponding to the positive connector 101 includes an external thread (not shown in the figure) that matches the internal thread 14, and the nut installation position corresponding to the negative connector 102 also includes an external thread that matches the internal thread 14.

[0058] Specifically, the photovoltaic connector provided in the present application includes a positive connector 101 and a negative connector 102. The positive connector 101 and the negative connector 102 both include a connecting nut 10. The connecting nut 10 is respectively sleeved on the outer periphery of the positive connector 101 and the outer periphery of the negative connector 102. The inner wall 12 of the connecting nut 10 includes an internal thread 14. The nut installation position corresponding to the positive connector 101 includes an external thread matched with the internal thread 14. Similarly, the nut installation position corresponding to the negative connector 102 also includes an external thread matched with the internal thread 14.

The present application is conducive to blind screwing by setting the guide groove 132 and the limit groove 131, thereby saving assembly time and further improving production efficiency.

[0059] Figure 6 FIG. 1 is a partial schematic diagram of a connecting nut provided in an embodiment of the present application. It should be noted that: Figure 6 The dimensions indicated in this application are only for reference and do not represent the actual dimensions and structure. Figure 6 Optionally, the minimum distance between the inner wall 12 and the outer wall 11 is L, L≥1mm.

[0060] Specifically, in order to improve the convenience of use of the connecting nut 10, the present application sets a positioning groove 13 on the outer wall 11 of the connecting nut 10. The setting of the positioning groove 13 will reduce the thickness of the connecting nut 10 in the area corresponding to the positioning groove 13. When the minimum distance L between the inner wall 12 and the outer wall 11 of the connecting nut 10 is less than 1mm, the wall thickness of the connecting nut 10 is thin, which will lead to poor quality, weak hardness and easy breakage of the connecting nut 10. In order to improve the stability of use of the connecting nut 10, the present application sets the minimum distance L between the inner wall 12 and the outer wall 11 of the connecting nut 10 to L≥1mm. The present application provides an optional implementation method that the minimum distance L between the inner wall 12 and the outer wall 11 of the connecting nut 10 is L=1mm; the present application provides another optional implementation method that the minimum distance L between the inner wall 12 and the outer wall 11 of the connecting nut 10 is L=1.1mm; the present application provides another optional implementation method that the minimum distance L between the inner wall 12 and the outer wall 11 of the connecting nut 10 is L=1.2mm.

[0061] Please refer to Figure 1 and Figure 6 Optionally, the minimum width of the positioning groove 13 along the second direction D2 is W, 4.9 mm≤W≤5.1 mm, and the second direction D2 surrounds the outer wall 11.

[0062] Specifically, the photovoltaic connector provided in the present application includes a positioning groove 13, and the positioning groove 13 is arranged along the outer wall 11 of the connecting nut 10. The minimum width of the positioning groove 13 along the second direction D2 is W. When the minimum width W of the positioning groove 13 along the second direction D2 is less than 4.9 mm, the width of the positioning groove 13 is small, which is not conducive to the alignment of the installation tool with the connecting nut 10. For example, it is not conducive to the alignment of the protrusion 21 of the unlocking tool 20 with the positioning groove 13. Moreover, if the width of the positioning groove 13 is small, the width of the protrusion 21 of the unlocking tool 20 is also small. , the strength of the protrusion 21 is poor; when the minimum width W of the positioning groove 13 along the second direction D2 is greater than 5.1mm, the width of the positioning groove 13 is relatively large, which will affect the number selection of the positioning grooves 13, and further affect the alignment of the unlocking tool 20 and the positioning groove 13; therefore, the present application sets the minimum width W of the positioning groove 13 along the second direction D2 to 4.9mm≤W≤5.1mm. Such a setting is not only conducive to the alignment of the unlocking tool 20 and the positioning groove 13, but also conducive to improving the limiting effect between the unlocking tool 20 and the positioning groove 13 along the second direction D2. The present application provides an optional implementation method that the minimum width W of the positioning groove 13 along the second direction D2 is 4.95mm; the present application provides another optional implementation method that the minimum width W of the positioning groove 13 along the second direction D2 is 5mm; the present application provides another optional implementation method that the minimum width W of the positioning groove 13 along the second direction D2 is 5.05mm.

[0063] Please refer to Figure 1 Optionally, the number of the positioning grooves 13 is n, 8≤n≤10.

[0064] Specifically, the photovoltaic connector provided by the present application includes a connecting nut 10. In order to facilitate the installation and removal of the connecting nut 10, a positioning groove 13 is set on the outer wall 11 of the connecting nut 10. The number of the positioning grooves 13 is n. When the number n of the positioning grooves 13 is less than 8, it is difficult to align the positioning grooves 13 and the unlocking tool 20, which is not conducive to improving production efficiency; when the number n of the positioning grooves 13 is greater than 10, the number of the positioning grooves 13 is large, and the wall thickness of the connecting nut 10 at the position where the positioning grooves 13 are set is thinner and the hardness is weaker, which reduces the use stability of the connecting nut 10 and increases the production difficulty; therefore, the present application sets the number n of the positioning grooves 13 to 8≤n≤10. Such a setting is conducive to the alignment of the unlocking tool 20 with the connecting nut 10, which is conducive to blind screwing, thereby saving assembly time, and further improving production efficiency. The present application provides an optional implementation method that the number n of the positioning grooves 13 is 8; the present application provides another optional implementation method that the number n of the positioning grooves 13 is 9; the present application provides another optional implementation method that the number n of the positioning grooves 13 is 10.

[0065] Please refer to Figure 1 and Figure 6 Optionally, the height of the positioning groove 13 along the first direction D1 is H, 8.4mm≤H≤8.6mm.

[0066] Specifically, the photovoltaic connector provided in the present application includes a connecting nut 10. In order to facilitate the installation and removal of the connecting nut 10, a positioning groove 13 is set on the outer wall 11 of the connecting nut 10. When installing and removing the connecting nut 10, an unlocking tool 20 is used to align with the connecting nut 10. The unlocking tool 20 includes a protrusion 21. After the unlocking tool 20 is aligned with the connecting nut 10, the protrusion 21 is located in the positioning groove 13. The height of the positioning groove 13 along the first direction D1 is H. When the height H of the positioning groove 13 along the first direction D1 is less than 8.4 mm, the height of the positioning groove 13 is smaller. , the contact area between the protrusion 21 and the positioning groove 13 is small, which affects the limiting effect; when the height H of the positioning groove 13 along the first direction D1 is greater than 8.6 mm, the height of the positioning groove 13 is relatively large, and the height of the protrusion 21 in the unlocking tool 20 is also relatively large. When installing or removing the connecting nut 10, the protrusion 21 is easy to break; therefore, the height H of the positioning groove 13 along the first direction D1 is set to 8.4 mm ≤ H ≤ 8.6 mm. Such a setting is conducive to the alignment and limiting between the unlocking tool 20 and the connecting nut 10, thereby improving the installation efficiency and further improving the production efficiency.

[0067] Please refer to Figure 1 and Figure 6 Optionally, the minimum thickness of the positioning groove 13 along the direction from the outer wall 11 to the inner wall 12 is D, 1.3mm≤D≤1.5mm.

[0068] Specifically, the photovoltaic connector provided in the present application includes a connecting nut 10. In order to facilitate the installation and disassembly of the connecting nut 10, a positioning groove 13 is set on the outer wall 11 of the connecting nut 10. When installing and disassembling the connecting nut 10, an unlocking tool 20 is used to align with the connecting nut 10. The unlocking tool 20 includes a protrusion 21. After the unlocking tool 20 is aligned with the connecting nut 10, the protrusion 21 is located in the positioning groove 13, and the minimum thickness of the positioning groove 13 along the outer wall 11 pointing to the inner wall 12 is D. When the minimum thickness D of the positioning groove 13 along the direction of the outer wall 11 pointing to the inner wall 12 is less than 1.3mm, the thickness of the positioning groove 13 is relatively small, and the limiting effect on the unlocking tooling 20 is relatively poor; when the minimum thickness D of the positioning groove 13 along the direction of the outer wall 11 pointing to the inner wall 12 is greater than 1.5mm, the thickness of the positioning groove 13 is relatively thick, which will affect the wall thickness of the connecting nut 10 in the area where the positioning groove 13 is located, and affect the hardness of the connecting nut 10; therefore, the minimum thickness D of the positioning groove 13 along the direction of the outer wall 11 pointing to the inner wall 12 is set to 1.3mm≤D≤1.5mm. Such a setting is conducive to improving the limiting effect of the positioning groove 13 on the unlocking tooling 20, and is conducive to reducing the influence of the positioning groove 13 on the hardness of the connecting nut 10. The present application provides an optional implementation manner in which the minimum thickness D of the positioning groove 13 along the direction of the outer wall 11 toward the inner wall 12 is 1.3 mm; the present application provides another optional implementation manner in which the minimum thickness D of the positioning groove 13 along the direction of the outer wall 11 toward the inner wall 12 is 1.4 mm; the present application provides yet another optional implementation manner in which the minimum thickness D of the positioning groove 13 along the direction of the outer wall 11 toward the inner wall 12 is 1.5 mm.
