Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0039] With the continuous development of the photovoltaic industry in the field of clean energy, photovoltaic modules are getting larger and larger, resulting in the junction boxes in photovoltaic modules gradually evolving from the original single-body junction box structure to the current split junction box. The split junction boxes of different manufacturers have different sizes and styles, resulting in the need to select suitable tooling to test the junction box cables, which in turn complicates the junction box testing. Furthermore, there is no existing tooling for testing the cables connected to the junction box, making it difficult to achieve the testing purpose for the cables connected to the junction box.

[0040] Therefore, how to provide a convenient device for testing the cables of the junction box is a technical problem that those skilled in the art need to solve urgently. For details, please refer to the following embodiments:

[0041] Example 1:

[0042] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a top view of a junction box cable testing device provided by an embodiment of the present invention. The junction box cable testing device may include:

[0043] Junction box fastening component 10, cable fastening component 20, motor 30 and bearing component 40;

[0044] The junction box fastening component 10, the cable fastening component 20, and the motor 30 are all arranged on the bearing component 40;

[0045] The junction box fastening component 10 is formed with a junction box limiting area of adjustable size;

[0046] The motor 30 is provided corresponding to the cable fastening component 20, and the rotor of the motor 30 is provided with a connection end for fixing the connection cable. It should be noted that the junction box limiting area formed by the junction box fastening component 10 in this embodiment is used to limit the junction box 1 in the junction box limiting area to fix the junction box 1, and the size of the junction box limiting area formed by the junction box fastening component 10 is adjustable. When facing junction boxes 1 of different sizes, the size of the junction box limiting area is adjusted to match the actual size of the junction box 1, and the junction box 1 is placed in the junction box limiting area. Accordingly, in this embodiment, when the cable fastening component 20 places the junction box 1 in the junction box limiting area, the cable 2 connected to the junction box 1 is placed in the cable fastening component 20, so that the cable 2 is fixed by the cable fastening component 20, and the rotor of the motor is used to drive the cable 2 to rotate, so as to detect the cable 2. It should be noted that the junction box cable testing device in this embodiment can also refer to Figure 2 and Figure 3 , Figure 2 A schematic front view of a junction box cable testing device provided by an embodiment of the present utility model; Figure 3 The present invention provides a schematic side view of a cable testing device for a junction box according to an embodiment of the present invention.

[0047] In this embodiment, the motor 30 is positioned corresponding to the cable fastening component 20, and the rotor of the motor 30 is provided with a connection end for securing the cable 2. Specifically, in this embodiment, by connecting the motor 30 to the end of the cable 2 away from the junction box 1 and securing the end of the cable 2 closer to the junction box 1 with the cable fastening component 20, the motor 30 can be used to drive the end of the cable 2 away from the junction box 1 to rotate or appear to rotate, thereby obtaining a specified torque on the cable 2, ensuring ease of testing. In this embodiment, a torque of 10N can be applied to the motor 30 to drive the bearing to rotate the cable 2. Specifically, when testing the cable 2, this embodiment may include the following steps: inserting the junction box 1 connected to the cable 2, securing the junction box 1 with the junction box fastening component 10, securing the cable 2 with the cable fastening component 20, turning on the chassis power, setting the device torque value to 10N, and applying it to the motor 30, causing the rotor in the motor 30 to rotate and drive the cable 2 to rotate, thereby obtaining a torque, which is then used to determine whether the tested cable 2 meets the standard. In addition, the structure of the junction box cable testing device in this embodiment when the junction box 1 and the cable 2 are placed can refer to Figure 4 , Figure 4 The present invention provides a schematic diagram of a structure in which a junction box 1 and a cable 2 are placed in a junction box cable testing device provided in an embodiment of the present invention, wherein the junction box 1 is placed in a junction box fastening component 10 , and the cable 2 is placed in a cable fastening component 20 .

[0048] Furthermore, it should be noted that the specific structure of the junction box fastening component 10 is not limited in this embodiment, as long as the size of the junction box limiting area in the junction box fastening component 10 is adjustable. Accordingly, the specific structure of the cable fastening component 20 is not limited in this embodiment, as long as it can fix the cable 2 and prevent it from rotating with the rotor in the motor 30. In this embodiment, the motor 30 can be a servo motor or other motor. Similarly, the specific structure of the bearing component 40 is not limited in this embodiment, as long as the junction box fastening component 10, the cable fastening component 20, and the electrode 30 can be connected to the surface of the bearing component 40. It is clear that in order for the junction box cable testing device to operate normally, it can also include a control component and a power supply component. The power supply component is used to supply energy to the motor 30, and the control component is used to control the torque value applied by the motor 30. The torque value of the rotor in the motor 30 is controlled by the control component, and then applied to the cable 2 to measure whether the cable 2 is qualified under the corresponding torque. In a specific embodiment, the junction box limiting area is adjustable in size and position. That is, the geometric center of the junction box limiting area can be adjusted to ensure that the junction box cable testing device of this embodiment can adapt to different junction boxes 1 with different cable 2 lead-out positions. Furthermore, the geometric center of the cable limiting area 21 can also be adjusted. The cable limiting area 21 is the area in the cable fastening component 20 where the cable 2 is placed.

[0049] Furthermore, in order to ensure the convenience of adjusting the size of the junction box limiting area, the junction box fastening component 10 may include a plurality of baffles that are combined to form the junction box limiting area;

[0050] At least part of the baffles are movable baffles, and the area enclosed by the baffles is the junction box limiting area.

[0051] It should be noted that in this embodiment, the area enclosed by the baffles serves as the junction box limiting zone, and at least a portion of the baffles is configured as a movable baffle, so that the size of the junction box limiting zone can be adjusted by moving the movable baffles. In this embodiment, by configuring a portion of the baffles enclosing the junction box limiting zone as movable baffles, the size or shape of the junction box limiting zone can be adjusted simply by moving the movable baffles, thereby improving the convenience of adjusting the size of the junction box limiting zone.

[0052] Furthermore, in order to ensure that the junction box cable test is completed smoothly, the junction box fastening component 10 may be provided with a movable baffle along the first preset direction;

[0053] The junction box fastening component 10 is provided with an opening for passing at least a cable; the opening is located on a side of the junction box fastening component 10 along the second preset direction, close to the cable fastening component 20; the first preset direction is perpendicular to the second preset direction; the second preset direction is the direction from the junction box fastening component 10 to the straight line where the cable fastening component 20 is located.

[0054] It should be noted that in this embodiment, a movable baffle is provided along a first preset direction on the junction box fastening component 10 to adjust the size of the junction box limit zone in the first direction. In this embodiment, the first preset direction is perpendicular to the direction from the junction box fastening component 10 to the line on which the cable fastening component 20 is located. When the junction box fastening component 10 is positioned along a second preset direction, i.e., the direction from the junction box fastening component 10 to the line on which the cable fastening component 20 is located, and toward one side of the cable fastening component 20, an opening is provided in the junction box fastening component 10 corresponding to the junction box 1 to allow at least the cable 2 to pass through, allowing the cable 2 to extend to the cable fastening component 20, thereby facilitating testing of the structural strength of the cable 2.

[0055] Furthermore, in order to improve the flexibility of position adjustment of the junction box 1 and the efficiency of testing the cable 2 , the junction box fastening component 10 may be configured to be open along the second preset direction.

[0056] It should be noted that, in this embodiment, the junction box fastening component 10 is set to be open along the second preset direction, that is, no baffle is set in the second preset direction of the junction box fastening component 10. Therefore, when the junction box 1 is placed in the junction box limit area, the position can be adjusted along the second preset direction, so that the cable fastening component 20 fixes the position of the cable 2 close to the side of the junction box 1, thereby improving the convenience of detecting the structural strength of the cable 2.

[0057] Furthermore, in order to ensure the simplicity of the movable baffle structure, the movable baffle may be configured to have an L-shaped cross section along a vertical section parallel to the first preset direction, including a side sub-baffle 11 and a bottom sub-baffle 12 forming the L-shaped cross section;

[0058] One end of the bottom sub-baffle 12 away from the side sub-baffle 11 is connected to the spring bolt 13 .

[0059] It should be noted that in this embodiment, the movable baffle is set to form an L-shaped shape along a vertical section parallel to the first preset direction, and the side sub-baffle 11 is used to adjust the junction box limit area. The bottom sub-baffle 12 is connected to the spring bolt 13 at one end away from the side sub-baffle 11, so that the position of the movable baffle can be adjusted by using the spring bolt 13, thereby achieving the adjustment of the junction box limit area, ensuring the flexibility of the junction box limit area adjustment and the convenience of the structure. The L-shaped baffle in this embodiment can refer to Figure 5 , Figure 5 An L-shaped baffle in a junction box cable testing device provided by an embodiment of the utility model.

[0060] Furthermore, in order to further improve the position adjustability of the baffles that form the limiting area of the junction box, the above-mentioned junction box fastening component 10 can be provided with a limiting baffle along the first preset direction, and the limiting baffle includes a first limiting sub-baffle 14 connected to the side sub-baffle 11, and a second limiting sub-baffle 15 arranged close to the spring bolt 13.

[0061] It should be noted that in this embodiment, a limiting baffle is provided, and the first limiting sub-baffle 14 of the limiting baffle is connected to the above-mentioned side sub-baffle 11, that is, the first limiting sub-baffle 14 moves together with the above-mentioned side sub-baffle 11, while the second limiting sub-baffle 15 of the limiting baffle is provided on the side away from the side sub-baffle 11. From the above description, it can be determined that the limiting area of the junction box in this embodiment is mainly formed by the distance between the first limiting sub-baffle 14 and the second limiting sub-baffle 15. In this case, the width of the above-mentioned L-shaped baffle can be flexibly set. The L-shaped baffle is only used to drive the movement of the first limiting sub-baffle 14, ensuring the specificity of the baffle function. It can be seen that in this embodiment, when the side sub-baffle 11 of the movable baffle moves, it drives the first limiting sub-baffle 14 to move toward or away from the second limiting sub-baffle 15.

[0062] Furthermore, in order to prevent the junction box 1 from directly contacting the cable fastening component 20 and affecting the accuracy of the cable 2 test, a protruding limiting structure 50 may be provided on the side of the cable fastening component 20 facing the junction box fastening component 10 .

[0063] It should be noted that in this embodiment, a raised limiting structure 50 is provided on the side of the cable fastening component 20 facing the junction box fastening component 10 to prevent the end of the junction box 1 that is close to the cable fastening component 20 from directly contacting the cable fastening component 20 when the junction box 1 is placed in the junction box limiting area, thereby ensuring the accuracy of the structural strength test of the cable 2. Furthermore, the raised limiting structure 50 can be provided on the cable fastening component 20, corresponding to the junction box limiting area. In this embodiment, when the junction box 1 is placed in the junction box limiting area, the raised limiting structure 50 separates the junction box 1 and the cable fastening component 20 to prevent direct contact between the two. In this embodiment, the height of the raised limiting structure 50 can be set to 2 mm.

[0064] Furthermore, in order to ensure that the rotor in the motor 30 drives the cable 2 to rotate away from the end of the junction box 1 and applies torque to the cable 2, the motor 30 can be connected to the cable fastening component 20 through a bearing component 60.

[0065] It should be noted that, in this embodiment, the rotor in the motor 30 rotates, and rotates the cable 2 through the bearing and applies torque to the cable 2 , thereby improving the convenience of testing the cable 2 .

[0066] The junction box cable testing device provided by the embodiment of the present invention includes a junction box fastening component 10, a cable fastening component 20, a motor 30, and a bearing component 40. The junction box fastening component 10, the cable fastening component 20, and the motor 30 are all arranged on the bearing component 40. The junction box fastening component 10 forms a junction box limiting area with an adjustable size. The motor 30 is arranged corresponding to the cable fastening component 20, and the rotor of the motor 30 is provided with a connection end for fixing the connection cable 2. By setting the size of the junction box limiting area adjustable, the present invention can adapt to testing junction boxes 1 of different sizes, and uses the cable fastening component 20 to fasten the cable 2, and uses the motor 30 to drive the cable 2 to rotate for testing, thereby improving the convenience of testing.

[0067] In addition, the embodiment of the present invention sets part of the baffles that form the limiting area of the junction box as movable baffles. The size or shape of the limiting area of the junction box can be adjusted by moving the movable baffles, thereby improving the convenience of adjusting the size of the limiting area of the junction box; the junction box fastening component 10 is set to be provided with a movable baffle along a first preset direction, so as to adjust the size of the limiting area of the junction box in the first direction, so as to facilitate testing the structural strength of the cable 2; the junction box fastening component 10 is set to be open along a second preset direction, so as to improve the flexibility of the cable fastening component 20 in fixing the position of the cable 2 close to the side of the junction box 1, thereby improving the convenience of testing the structural strength of the cable 2; the position of the movable baffle is adjusted by using the spring bolt 13 to achieve docking The adjustment of the junction box limit area ensures the flexibility of the junction box limit area adjustment and the convenience of the structure; the junction box limit area is formed by the distance between the first limit sub-baffle 14 and the second limit sub-baffle 15, and the width of the L-shaped baffle can be flexibly set at this time. The L-shaped baffle is only used to drive the first limit sub-baffle 14 to move, thereby ensuring the specificity of the baffle function; by providing a raised limiting structure 50 on the side of the cable fastening component 20 facing the junction box fastening component 10, it is avoided that when the junction box 1 is placed in the junction box limit area, the end of the junction box 1 that is close to the cable fastening component 20 directly contacts the cable fastening component 20, thereby ensuring the accuracy of the structural strength detection of the cable 2; the cable 2 is rotated by the bearing and torque is applied to the cable 2, thereby improving the convenience of testing the cable 2.
