[0034] Next, refer to Figures 1-9 to describe the photovoltaic junction box 100 according to the first aspect embodiment of the present invention.

[0035] As Figures 1-9 shown, the photovoltaic junction box 100 according to the first aspect embodiment of the present invention includes a housing 1, a conductive member 2, a conductive plug-in connector 3, and a cable 200.

[0036] Specifically, the housing 1 has an accommodation cavity 11 and a through hole 12. The through hole 12 communicates with the accommodation cavity 11. The housing 1 has a first direction (for example, Figure 2 the up and down direction in Figure 2 ), a second direction (for example, Figure 4 the left and right direction in

[0037] Among them, the housing 1 serves as the main structural component of the outer contour of the photovoltaic junction box 100, mainly playing the role of protecting and accommodating the internal structural components. The conductive member 2 is used to conduct current. The cable 200 can be used to transmit electric energy or electrical signals. The conductive plug-in connector 3 plays the role of electrically connecting the conductive member 2 and the cable 200. For example, in Figure 2 and Figure 3 In the example of, a through hole 12 is formed in a side wall of the housing 1 in the second direction. The through hole 12 communicates with the accommodation cavity 11. During installation, one end of the cable 200 enters the accommodation cavity 11 through the through hole 12, and the other end of the conductive plug-in connector 3 is inserted into the cable 200 to complete the electrical connection between the conductive member 2, the conductive plug-in connector 3 and the cable 200. Among them, both ends of the cable 200 can be respectively connected to the photovoltaic cell and the conductive plug-in connector 3 to realize the electrical connection between the photovoltaic cell and the photovoltaic junction box 100; or, both ends of the cable 200 can be respectively connected to two conductive plug-in connectors 3 to realize the electrical connection between adjacent two photovoltaic cells. Thus, compared with the traditional photovoltaic junction box, the connector and the wire coiling steps are saved, and the connection method between the conductive plug-in connector 3 and the cable 200 is simple, reducing the assembly difficulty of the photovoltaic junction box 100 and the photovoltaic cell, improving the assembly efficiency of the photovoltaic module, and at the same time ensuring the power generation efficiency of the photovoltaic power generation system.

[0038] In addition, one end of the conductive plug-in connector 3 is connected to the conductive member 2 to realize the electrical connection between the conductive member 2 and the cable 200, avoiding the need to use a traditional connector to reconnect the conductive member 2 and the cable 200.

[0039] During the actual assembly process of the photovoltaic junction box 100, cables 200 of any length can be selected according to the actual distance between the photovoltaic junction box 100 and the photovoltaic cell, that is, after simple processing (such as cutting) of the cables 200, they can be used. At the same time, the separated design of the photovoltaic junction box 100 and the cable 200 facilitates the assembly of the cable 200 after the photovoltaic junction box 100 is carried to the installation position, thereby improving the convenience of use of the photovoltaic junction box 100.

[0040] According to the photovoltaic junction box 100 of the embodiment of the present invention, by connecting one end of the conductive plug-in connector 3 to the conductive member 2 and inserting the other end of the conductive plug-in connector 3 into the through hole 12 to be inserted into the cable 200, the electrical connection between the cable 200 and the photovoltaic junction box 100 is realized. Thus, compared with the traditional photovoltaic junction box, the connector and the wire coiling steps are saved, and the connection method between the conductive plug-in connector 3 and the cable 200 is simple, reducing the assembly difficulty of the photovoltaic junction box 100 and the photovoltaic cell, improving the assembly efficiency of the photovoltaic module, and at the same time ensuring the power generation efficiency of the photovoltaic power generation system.

[0041] According to some embodiments of the present invention, referring to Figure 2 and Figure 3, along the direction towards the through hole 12, the cross-sectional area of the conductive plug-in connector 3 gradually decreases. That is to say, the cross-sectional area of the end of the conductive plug-in connector 3 far from the through hole 12 is the largest, and the above-mentioned end of the conductive plug-in connector 3 is connected to the conductive member 2, increasing the contact area between the conductive plug-in connector 3 and the conductive member 2 and improving the connection stability between the conductive plug-in connector 3 and the conductive member 2. The cross-sectional area of the end of the conductive plug-in connector 3 extending into the through hole 12 is the smallest, increasing the sharpness of the conductive plug-in connector 3 on the basis of meeting its own structural strength, facilitating the above-mentioned other end of the conductive plug-in connector 3 to be inserted into the cable 200, and further improving the assembly efficiency of the photovoltaic junction box 100 and the cable 200.

[0042] According to some specific embodiments of the present invention, referring to Figure 2 and Figure 3 , the conductive plug-in connector 3 includes a first conductive section 31, a second conductive section 32 and a third conductive section 33. The first conductive section 31 extends along the second direction, and the first conductive section 31 is connected to the conductive member 2. The second conductive section 32 is connected to the first conductive section 31, and the second conductive section 32 extends along the first direction. The third conductive section 33 is connected to the second conductive section 32, and the third conductive section 33 extends along the second direction. In the second direction, the length of the third conductive section 33 is greater than the length of the first conductive section 31. That is to say, the shape of the cross-section of the conductive plug-in connector 3 along the first direction is generally Z-shaped. Among them, both ends of the first conductive section 31 are respectively connected to the conductive member 2 and the second conductive section 32 to complete the electrical connection between the conductive member 2 and the conductive plug-in connector 3. Both ends of the second conductive section 32 are respectively connected to the first conductive section 31 and the third conductive section 33. With such a setting, by using the second conductive section 32, the distance between the third conductive section 33 and the bottom wall of the housing 1 in the first direction can be increased, so that the through hole 12 is generally provided in the middle of the side wall of the housing 1, avoiding interference between the cable 200 and the conductive member 2 during installation, and facilitating the threading of the cable 200 through the through hole 12.

[0043] In addition, in the second direction, the length of the third conductive section 33 is greater than the length of the first conductive section 31. Since the first conductive section 31 is fixedly connected to the conductive member 2, the length of the first conductive section 31 is set to be smaller, so that while meeting the connection requirement with the conductive member 2, the weight of the conductive member 2 is reduced, and the third conductive section 33 is inserted into the cable 200. The length of the third conductive section 33 is set to be longer, which is beneficial to inserting as much of the third conductive section 33 as possible into the cable 200, thereby ensuring the connection stability between the third conductive section 33 and the cable 200.

[0044] In some alternative embodiments, referring to Figure 2 and Figure 3, on one side of the conductive member 2 in the first direction, a diode 21 is provided. The diode 21 and the conductive connector 3 are respectively located at both ends of the conductive member 2 in the second direction. The diode 21 mainly functions to prevent reverse current (i.e., in a photovoltaic power generation system, when the photovoltaic panel is irradiated by sunlight, electrical energy is generated. When a reverse current phenomenon occurs in the photovoltaic power generation system, that is, the photovoltaic panel absorbs energy from the load or the power grid instead of transmitting energy to the load or the power grid. The reverse current phenomenon will cause the use efficiency of the photovoltaic power generation system to decrease and even damage the photovoltaic components) and control the current flow direction, ensuring that the photovoltaic panel only outputs energy to the power grid or the load. Since the diode 21 is the main heat-generating component in the photovoltaic junction box 100, the diode 21 and the cable 200 are respectively installed at both ends of the conductive member 2 in the second direction, reducing the risk of thermal interference between the cable 200 and the diode 21, thereby ensuring the operating stability of the diode 21 and the cable 200.

[0045] According to some specific embodiments of the present invention, referring to Figures 2-9 , the housing 1 includes a box body 13 and a box cover 14. A first partition 131 is provided inside the box body 13. The first partition 131 extends along the circumferential direction of the box body 13 and divides the interior of the box body 13 into a first groove 1311 and a second groove 1312. The conductive member 2, the diode 21, and the conductive connector 3 are all arranged in the first groove 1311. A second partition 141 is provided inside the box cover 14. The second partition 141 extends along the circumferential direction of the box cover 14 and divides the inner wall of the box cover 14 into a third groove 1411 and a fourth groove 1412. The second partition 141 is fitted in the second groove 1312, and the side wall of the box body 13 is fitted in the fourth groove 1412.

[0046] In this way, after the photovoltaic junction box 100 is assembled, the first partition 131, the second partition 141, the side wall of the box body 13, and the side wall of the box cover 14 are sequentially arranged in the direction away from the center of the housing 1. That is to say, the second partition 141 on the box cover 14 is fitted with the second groove 1312, the side wall of the box body 13 is fitted with the fourth groove 1412, and the side wall of the box body 13 and the first partition 131 are arranged on both sides of the second partition 141. Thus, the box cover 14 and the box body 13 form a plug-in fit relationship, thereby ensuring the connection firmness between the box cover 14 and the box body 13.

[0047] Among them, a plurality of sealing capsules 15 are provided in the second groove 1312, and the second partition 141 is adapted to squeeze the sealing capsules 15 so that the sealing glue fills the second groove 1312; and / or a plurality of sealing capsules 15 are provided in the fourth groove 1412, and the side wall of the box body 13 is adapted to squeeze the sealing capsules 15 so that the sealing glue fills the fourth groove 1412. In the description of the present invention, the meaning of "a plurality" is two or more. Among them, a plurality of sealing capsules 15 can be provided only in the second groove 1312 (such as Figures 2-5as shown in the figure); alternatively, a plurality of sealing capsules 15 (not shown in the figure) may be provided only in the fourth groove 1412; or, a plurality of sealing capsules 15 (not shown in the figure) may be provided in both the second groove 1312 and the fourth groove 1412.

[0048] As Figures 2-5 shown in the figure, a plurality of sealing capsules 15 are provided only in the second groove 1312, and the plurality of sealing capsules 15 are arranged at intervals along the circumferential direction of the box body 13 in the second groove 1312. During installation, the second partition 141 on the box cover 14 can be pre-fitted into the second groove 1312 first. At this time, the side wall of the box body 13 is pre-fitted into the fourth groove 1412, and then the box body 13 and the box cover 14 are moved relative to each other, that is, the end of the second partition 141 facing the second groove 1312 presses the sealing capsule 15, causing the sealing capsule 15 to rupture, and the sealing glue in the sealing capsule 15 overflows and fills the gap between the second partition 141 and the inner wall of the second groove 1312. When the sealing glue cures, the stable connection between the box body 13 and the box cover 14 is completed. Thereby, while improving the connection stability of the photovoltaic junction box 100, the sealing performance of the photovoltaic junction box 100 is ensured.

[0049] Further, along the direction towards the box body 13, the thickness of the second partition 141 gradually decreases in the second direction; and / or along the direction towards the box cover 14, the thickness of the side wall of the box body 13 gradually decreases in the second direction. That is to say, when the second groove 1312 is filled with the sealing capsule 15, along the direction towards the box body 13, the thickness of the second partition 141 gradually decreases in the second direction (as Figure 2 and Figure 4 shown in the figure); when the fourth groove 1412 is filled with the sealing capsule 15, along the direction towards the box cover 14, the thickness of the side wall of the box body 13 gradually decreases in the second direction (not shown in the figure).

[0050] As Figure 2 and Figure 4 shown in the figure, a plurality of sealing capsules 15 are provided only in the second groove 1312. The thickness of the end of the second partition 141 away from the box body 13 is the largest, and the thickness of the end of the second partition 141 facing the box body 13 is the smallest. Thus, by reducing the sharpness of the end of the second partition 141 facing the box body 13, the pressure exerted by the second partition 141 on the sealing capsule 15 is increased, which is beneficial to the second partition 141 squeezing and breaking the sealing capsule 15 in the second groove 1312.

[0051] Further, at least one card slot 16 is formed on one of the outer peripheral surface of the side wall of the box body 13 and the inner peripheral surface of the side wall of the lid 14, and at least one buckle group 17 is formed on one of the outer peripheral surface of the side wall of the box body 13 and the inner peripheral surface of the side wall of the lid 14. The buckle group 17 includes a plurality of buckles 171 spaced apart in a first direction, and one of the plurality of buckles 171 is fitted into the card slot 16. When the card slot 16 is formed on the outer peripheral surface of the side wall of the box body 13, the buckle group 17 is formed on the inner peripheral surface of the side wall of the lid 14 (as Figure 4 and Figure 5 shown); when the buckle group 17 is formed on the outer peripheral surface of the side wall of the box body 13, the card slot 16 is formed on the inner peripheral surface of the side wall of the lid 14 (not shown in the figure).

[0052] Referring to Figure 4 and Figure 5 , two buckle groups 17 are formed on the inner peripheral surface of the side wall of the lid 14. The two buckle groups 17 are formed on the inner peripheral surfaces of the two side walls of the lid 14 in a third direction. Each buckle group 17 includes two buckles 171, and the two buckles 171 are spaced apart in the first direction of the lid 14. Correspondingly, the card slot 16 is provided on the outer peripheral surface of the side wall of the box body 13. During installation, the lid 14 and the box body 13 approach each other so that the second partition 141 enters the second groove 1312, and the buckle 171 facing the bottom wall of the second groove 1312 is engaged with the card slot 16, thereby realizing the pre-fitting of the box body 13 and the lid 14; after the cable 200 and the conductive connector 3 are fitted, a force is applied to make the box body 13 and the lid 14 approach each other further, so that the buckle 171 facing the bottom wall of the second groove 1312 is disengaged from the card slot 16 until the buckle 171 away from the bottom wall of the second groove 1312 is engaged with the card slot 16, and the second partition 141 can break the sealing capsule 15, that is, the assembly of the photovoltaic junction box 100 and the cable 200 is completed. Thereby, the assembly difficulty of the photovoltaic junction box 100 and the cable 200 is reduced, and the assembly efficiency of the photovoltaic junction box 100 and the cable 200 is improved.

[0053] At the same time, the connection method of the cooperation between the buckle group 17 and the card slot 16 simplifies the connection and disassembly difficulty between the box body 13 and the lid 14 compared with other connection methods such as welding and bonding, thereby improving the user experience.

[0054] Further, a plurality of limiting protrusions 1413 are provided on one side of the second partition 141 adjacent to the side wall of the lid 14. The plurality of limiting protrusions 1413 are spaced apart along the circumferential direction of the lid 14, and each limiting protrusion 1413 extends in the first direction. As Figure 7As shown, two limiting protrusions 1413 are spaced on one side of the second partition 141 adjacent to the side wall of the box cover 14. In the third direction, the sum of the thicknesses of the limiting protrusion 1413 and the second partition 141 is equal to the width of the second groove 1312. During the assembly of the box cover 14 and the box body 13, the limiting protrusion 1413 limits the box cover 14 and the box body 13. While ensuring a large gap is formed between the second partition 141 and the inner wall of the second groove 1312 to facilitate the filling of the sealant overflowing from the sealing capsule 15, relative displacement between the box cover 14 and the box body 13 is avoided, thereby improving the stability during the pre-assembly of the box cover 14 and the box body 13.

[0055] Furthermore, a heat dissipation member 142 is provided in the third groove 1411, and one end of the heat dissipation member 142 abuts against the cable 200. Refer to Figures 2-5 , and in combination with Figure 7 , one end of the heat dissipation member 142 in the third groove 1411 abuts against the cable 200 in the first direction. Thus, while realizing the heat dissipation effect of the heat dissipation member 142 on the heat generated by the cable 200, the heat dissipation member 142 can also press the cable 200 in the first direction, thereby restricting the movement of the cable 200 in the housing 1, and further ensuring the reliable insertion of the cable 200 and the conductive connector 3.

[0056] Furthermore, a boss 132 is provided in the first groove 1311, and the boss 132 extends in the direction towards the box cover 14, and the free end of the boss 132 abuts against the cable 200. As shown in Figure 2 and Figure 3 , along the first direction, the ends of the boss 132 and the heat dissipation member 142 are opposite to each other, and the free end of the boss 132 abuts against the cable 200 along the radial direction of the cable 200, which is conducive to the cooperation between the boss 132 and one end of the heat dissipation member 142 to clamp the cable 200 in the radial direction of the cable 200, thereby restricting the movement of the cable 200 in the housing 1, and further improving the installation stability of the cable 200 in the housing 1.

[0057] According to some specific embodiments of the present invention, refer to Figure 2 and Figure 3, the conductive member 2 includes a fourth conductive section 22 and a fifth conductive section 23. The fourth conductive section 22 extends along the second direction. The fifth conductive section 23 is connected to one end of the fourth conductive section 22 in the second direction. The fifth conductive section 23 extends along the first direction, and the fifth conductive section 23 abuts against the end of the cable 200. That is to say, the fourth conductive section 22 is parallel to the bottom wall of the housing 1 to increase the connection stability between the fourth conductive member 2 and the bottom wall of the housing 1. The fifth conductive section 23 is provided at one end of the fourth conductive section 22 adjacent to the through hole 12. The fifth conductive member 2 abuts against the end of the cable 200 to limit the length of the cable 200 extending into the housing 1, avoiding excessive extension of the cable 200 in the housing 1, thereby improving the use stability of the photovoltaic junction box 100.

[0058] Further, as Figure 4 and Figure 5 shown, the conductive member 2 further includes a sixth conductive section 24. The sixth conductive section 24 is connected to one end of the fourth conductive section 22 in the third direction. The sixth conductive section 24 extends along the first direction to extend the dimension of the conductive member 2 in the third direction. While the conductive member 2 meets the use requirements of the electrical connection between the diode 21 and the cable 200, it is beneficial to the miniaturized design of the photovoltaic junction box 100 to improve the applicability of the photovoltaic junction box 100. Wherein, the length of the sixth conductive section 24 in the first direction is greater than the length of the fifth conductive section 23.
