Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic component testing, in particular to a side-insertion photovoltaic component testing tool. Background Art

[0002] Since the sizes of component junction boxes in many domestic photovoltaic plants are different, the traditional vertical test tooling can only adapt to junction boxes of regular lengths and cannot adapt to shorter component junction boxes. At the same time, in actual working conditions, the two test modules of the vertical test tooling are set in the same direction. When testing, after one connector of the junction box is connected to the corresponding test module, the other connector of the junction box needs to be twisted and connected to another test module in the same direction, resulting in unreliable fixation of the connector after connection, and the copper core inside the connector is easily damaged after twisting, resulting in unstable function. Utility Model Content

[0003] In response to the shortcomings of the above-mentioned prior art, the present application provides a side-plug-in photovoltaic module testing tool. The testing tool is non-fixed, and each test module is slidably connected to a rod-type support body. The relative distance is adjusted axially to adapt to junction boxes of different lengths. At the same time, the side-plug-in interface setting has the advantages of reliable plug-in fixation and intact copper core function inside the junction box connector when in use.

[0004] The technical solution adopted by the utility model to solve the above technical problems is as follows:

[0005] A side-insertion photovoltaic module testing tool comprises a rod-type support body and a first test module and a second test module slidably arranged on the rod-type support body, wherein the first test module and the second test module both have a test access end for connecting a wire box, and the first test module and the second test module are arranged opposite to each other along the axial direction of the rod-type support body.

[0006] Furthermore, the first test module and the second test module have the same structure.

[0007] Furthermore, the first test module includes an integrated fixing module slidably set on a rod-type supporting body and a fixed baffle located below the integrated fixing module for fixing, a guide module is set at one lateral end of the integrated fixing module, a contact copper core group is set between the guide module and the integrated fixing module, and a contact copper sheet is also set on the upper surface of the integrated fixing module.

[0008] Furthermore, the contact copper core group includes a guiding copper core positive electrode and a guiding copper core negative electrode.

[0009] Furthermore, the contact copper core group is arranged on a latch seat, and a groove is provided on the end surface of the integrated fixing module for mounting the contact copper core group, and the latch seat is embedded in the groove.

[0010] The beneficial effects of the utility model are as follows:

[0011] Compared with the prior art, the photovoltaic module testing tooling provided by the utility model is non-fixed, and two test modules are arranged along the axial direction of the rod-type support body. At the same time, each test module is slidably connected to the rod-type support body in the form of a slider. When the two ends of the wire box are connected to the corresponding test modules, the relative distance can be adjusted axially to adapt to wire boxes of different lengths, thereby improving the flexibility and adaptability of use.

[0012] Compared with the prior art, the photovoltaic module testing tool provided by the utility model is a side-plug type. Compared with the traditional fixed-type interfaces that are arranged in the same direction, the interfaces of the testing tool of the utility model are arranged relatively to each other. When in use, the connectors at both ends of the junction box can be tested without twisting or connecting. On the one hand, it provides the fixed reliability of the connection, and on the other hand, it ensures that the copper core inside the junction box connector is in good function.

[0019] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0020] The utility model provides a side-insertion photovoltaic component testing tool, which aims to solve the problem that traditional vertical testing tools cannot adapt to shorter component box, and optimize the problem that traditional vertical testing tools need to twist the joints when plugging in due to the same-direction interface.

[0021] like Figure 1-5 As shown, the side-insertion photovoltaic module testing tool of the utility model includes a pole-type support body 1 and a first test module 2 and a second test module 3 slidably arranged on the pole-type support body 1, the first test module 2 and the second test module 3 both have a test access terminal for connecting a junction box, and the first test module 2 and the second test module 3 are relatively arranged along the axial direction of the pole-type support body 1.

[0022] Through the above technical solution, two test modules for connecting the wire boxes are installed in a non-fixed form on the rod-type support body 1. After the connectors at both ends of the wire box are plugged into the first test module 2 and the second test module 3, the distance between the two test modules is adjustable, so as to adapt to wire boxes of different lengths for testing, thereby overcoming the defect that traditional fixed test tools can only adapt to wire boxes of upward compatible sizes.

[0023] In some embodiments, the first test module 2 and the second test module 3 have the same structure.

[0024] In some embodiments, the first test module 2 includes an integrated fixing module 21 slidably set on the rod-type supporting body 1 and a fixed baffle 22 located below the integrated fixing module 21 for fixing. A guide module 23 is set at one lateral end of the integrated fixing module 21, and a contact copper core group 24 is set between the guide module 23 and the integrated fixing module 21. A contact copper sheet 25 is also set on the upper surface of the integrated fixing module 21.

[0025] Through the above technical scheme, a test module with reasonable structural design and small volume after integration is provided. Taking the MC3 wire box test as an example, the guide module 23 is used for inserting and fixing the component MC4 head; the guide copper core positive electrode 241 is used to contact the internal copper core of the MC4 head when the component MC4 head is inserted to form a positive current and voltage conduction; the guide copper core negative electrode 242 is used to contact the internal copper core of the MC4 head when the component MC4 head is inserted to form a negative current and voltage conduction; the contact copper sheet 25 is used to transmit the current, voltage and other parameters generated by the component to the probe of the test equipment (note: it cannot be virtually connected with the test copper needle); the integrated fixing module 21 is used to integrate the guide module 23, the guide positive and negative copper cores, and the contact copper sheet 25 into one body. The fixed baffle 22 is used to connect and fix the integrated fixing module 21 to the rod-type support body 1 with a hexagon socket screw.

[0026] In some embodiments, the contact copper core group 24 includes a guide copper core positive electrode 241 and a guide copper core negative electrode 242 .

[0027] In some embodiments, the contact copper core group 24 is disposed on a latch seat 26 , and a groove 27 is provided on the end surface of the integrated fixing module 21 for mounting the contact copper core group 24 , and the latch seat 26 is embedded in the groove 27 .

[0028] Through the above technical solution, the structure of the test module can be optimized, while avoiding the interference of the test on the insertion structure.

[0029] The working principle of this utility model:

[0030] When in use, taking the MC4 wire box as an example, the relative distance between the first test module 2 and the second test module 3 is adjusted by sliding according to the length of the connector of the MC4 wire box, the connectors at both ends of the wire box are respectively inserted into the guide module 23 of the corresponding test module and fixed, and the probe of the external test equipment is connected to the contact copper sheet 25 for testing.
