A clamping plate is provided on the side of the workbench, and a fastening mechanism and a square plate are provided on the axis of the clamping plate for fixing the photovoltaic module junction box connector.

[0007] The fastening mechanism includes a transmission part and a pushing part. The transmission part includes a screw that is threaded onto a square plate. The tail end of the screw is rotatably connected to the pushing part. When the screw rotates, it drives the pushing part to move back and forth along the axis by cooperating with the square plate.

[0008] In a preferred embodiment, the transmission unit further includes a first limiting plate and a second limiting plate fixedly connected to the tail end of the screw, with a gap between the first limiting plate and the second limiting plate, and the other end of the screw is designed with a T-shaped handle.

[0009] In a preferred embodiment, the pushing part includes a fixing member, the screw is connected to the movable fixing member via a connecting post, and the tail end of the screw is rotatably connected to the inner wall of the connecting post.

[0010] In a preferred embodiment, the connecting post has a through hole, the screw passes through the through hole and is rotatably connected to the connecting post, and the first limiting plate and the second limiting plate are respectively disposed on both sides of the through hole.

[0011] In a preferred embodiment, the screw and the square plate are threaded together as follows: the screw passes through a threaded hole in the square plate, and axial displacement is achieved by rotating the screw.

[0012] In a preferred embodiment, the card plate is a limiting baffle that is vertically fixed to the end of the storage slot.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The phrase "in a preferred embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0025] like Figures 1-2 As shown, a photovoltaic module junction box connector testing device includes a workbench 1 and a testing instrument 4 set on the workbench 1. A clamping plate 12 is provided on the side of the workbench 1, and a fastening mechanism 2 and a square plate 3 are provided on the axis of the clamping plate 12 for fixing the photovoltaic module junction box connector.

[0026] The fastening mechanism 2 includes a transmission part and a pushing part. The transmission part includes a screw 20, which is threaded onto the square plate 3. The tail end of the screw 20 is rotatably connected to the pushing part. When the screw 20 rotates, it drives the pushing part to move back and forth along the axis by cooperating with the square plate 3.

[0027] In the above embodiment, when the device is needed to test the photovoltaic module junction box connector, the photovoltaic module junction box connector is first placed in the storage slot 11 on the workbench 1. Then, the bottom of the photovoltaic module junction box connector is pushed to contact the side wall of the card plate 12. Then, the screw 20 is rotated, and the screw 20 drives the pushing part to move forward. When the fixing part 22 moves forward, the photovoltaic module junction box connector placed in the storage slot 11 can be fixed between the card plate 12 and the fixing part 22. After tightening, the testing instrument 4 is used to test the photovoltaic module junction box connector. After completion, the screw 20 is rotated in the opposite direction to move the fixing part 22 backward, thereby removing the photovoltaic module junction box connector.

[0028] It should be further explained that the testing instrument 4 used in the test is a testing device in the prior art. During the test, the testing head 41 is used to test the connection points on the photovoltaic module junction box connector, etc. The appropriate testing device can be selected according to different testing components or positions to test the photovoltaic module junction box connector. The testing methods and means are existing technologies, so they will not be described in detail here.

[0029] like Figures 3-4 As shown, the transmission part also includes a first limiting plate 201 and a second limiting plate 202 fixedly connected to the tail end of the screw 20. There is a gap between the first limiting plate 201 and the second limiting plate 202. The other end of the screw 20 is designed with a T-shaped handle. The pushing part includes a fixing member 22. The screw 20 is connected to the movable fixing member 22 through a connecting post 21. The tail end of the screw 20 is rotatably connected to the inner wall of the connecting post 21. A through hole 211 is opened on the connecting post 21. The screw 20 passes through the through hole 211 and is rotatably connected to the connecting post 21. The first limiting plate 201 and the second limiting plate 202 are respectively arranged on both sides of the through hole 211.

[0030] In the above embodiment, when the screw 20 rotates in the square plate 3, the tail end of the screw 20 rotates in the through hole 211 opened in the connecting post 21. Since the first limiting plate 201 and the second limiting plate 202 hold the connecting post 21 between the two plates, when the screw 20 moves forward, the limiting plate 201 and the second limiting plate 202 can drive the fixing member 22 to move axially synchronously through the connecting post 21, thereby fixing the photovoltaic module junction box connector placed in the storage slot 11. The side of the fixing member 22 that contacts the photovoltaic module junction box connector is provided with a rubber surface to prevent scratches on the surface of the photovoltaic module junction box connector during fixing.

[0031] Furthermore, the other end of the screw 20 is designed with a T-shaped handle to make it easy for workers to hold the screw 20 and rotate it, preventing it from slipping out of their hands while rotating.

[0032] like Figure 3As shown, the screw 20 and the square plate 3 are threaded together as follows: the screw 20 passes through the threaded hole provided in the square plate 3, and axial displacement is achieved by rotating the screw 20.

[0033] In the above embodiment, when the screw 20 rotates, the thread on the screw 20 engages with the screw hole on the square plate 3, allowing the screw 20 to move back and forth during rotation.

[0034] like Figure 1 As shown, the card plate 12 is a limiting baffle that is vertically fixed to the end of the storage slot 11.

[0035] In the above embodiment, the card plate 12 is set at the end of the storage slot 11. After the photovoltaic module junction box connector is placed in the storage slot 11, the photovoltaic module junction box connector is moved to contact the card plate 12, so that one side of the photovoltaic module junction box connector has a fixed contact point, and the photovoltaic module junction box connector is initially fixed on one side. The area of ​​the storage slot 11 is larger than the volume of the photovoltaic module junction box connector, so that photovoltaic module junction box connectors of different specifications can be placed in the storage slot 11.

[0036] The working principle of this utility model is as follows: When the device is needed to test the photovoltaic module junction box connector, the photovoltaic module junction box connector is first placed in the storage slot 11 on the workbench 1. Then, the bottom of the photovoltaic module junction box connector is pushed to contact the side wall of the card plate 12. Then, the screw 20 is rotated. When the screw 20 rotates on the square plate 3, the screw 20 can move forward or backward. With the setting of the first limiting plate 201 and the second limiting plate 202, when the screw 20 rotates and moves back and forth, the fixing part 22 can be moved back and forth through the connecting column 21. When the fixing part 22 moves forward, the photovoltaic module junction box connector placed in the storage slot 11 can be fixed between the card plate 12 and the fixing part 22. After tightening, the testing instrument 4 is used to test the photovoltaic module junction box connector. After completion, the screw 20 is rotated in the opposite direction to move the fixing part 22 backward, thereby removing the photovoltaic module junction box connector.

[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
