Both the tool body 11 and the first connector 12 may be connected to the support 10. Moreover, since the electric cables 13 can be constrained in the containing cavities inside the rack 10, the electric cables 13 are prevented from being exposed. Correspondingly, the surface that can avoid electric cable 13 to strike the photovoltaic module 20 that awaits measuring causes the subassembly to split secretly, thereby, can promote test fixture's safe in utilization.

In some optional embodiments of the present application, the two ends of the support 10 are respectively connected with an elastic connection mechanism 17, and the elastic connection mechanism 17 may be configured to be mounted on a frame 21 of the photovoltaic module 20 to be tested. In the embodiment of the application, elastic connection mechanism 17 is respectively arranged at two ends of support 10, and elastic connection mechanism 17 is respectively connected to frame 21, namely fixed at two ends of support 10, the test tool can be improved in the installation reliability of the test tool on photovoltaic module 20 to be tested. Moreover, since the elastic connection mechanism 17 has a certain elastic deformation capability, the elastic connection mechanism 17 can be quickly connected to the frame 21 through the elastic deformation of the elastic connection mechanism 17, and the elastic connection mechanism 17 with the elastic deformation capability can adapt to photovoltaic modules 20 with different sizes and specifications.
Referring to fig. 8, a schematic structural diagram of an elastic connection mechanism according to an embodiment of the present application is shown, and referring to fig. 9, a schematic structural diagram of another angle of the elastic connection mechanism shown in fig. 8 is shown. As shown in fig. 8 and 9, the elastic connection mechanism 17 may specifically include: a connecting body 171, an elastic member 172, and a connecting member 173; wherein, the connecting body 171 is fixed at the end of the bracket 10, the elastic member 172 is connected between the connecting body 171 and the connecting member 173, and the connecting member 173 is used for connecting with the frame 21 of the photovoltaic module 20 to be tested.
In the embodiment of the present application, the elastic member 172 is connected between the connecting body 171 and the connecting member 173, and the elastic member 172 can be elastically deformed to extend and contract the elastic connecting mechanism 17 to adjust the distance between the connecting member 173 and the connecting body 171. In this way, during the process of installing the elastic connection mechanism 17 to the photovoltaic module 20 to be tested, the elastic member 172 may be compressed to shorten the distance between the elastic member and the connection body 171, so as to facilitate the placement of the connection member 173 in the frame 21 of the photovoltaic module 20 to be tested. Then, the elastic member 172 is released, and the connecting member 173 can be connected to the frame 21 of the photovoltaic module 20 to be tested under the automatic restoring force of the elastic member 172, so that the installation efficiency is high. Moreover, after the connecting member 173 is connected to the frame 21 of the photovoltaic module 20 to be tested, the elastic member 172 may form a pre-pressure on the connecting member 173, and the connecting member 173 may be reliably connected to the frame 21 under the pre-pressure of the elastic member 172, so that the installation reliability of the testing tool on the photovoltaic module 20 to be tested may be improved.

Specifically, the fixing portion 1711 and the extending portion 1712 of the connecting body 171 may be disposed at an angle. When the elastic connection mechanism 17 needs to be connected to the bracket 10, the fixing portion 1711 may be mounted in the second mounting hole 103 at the end of the bracket 10. Because the elastic member 172 is sleeved on the extension portion 1712, the elastic member 172 extends and contracts along the length direction of the extension portion 1712, so that the connecting member 173 can be driven to move along the length direction of the extension portion 1712 correspondingly.
In practice, resilient attachment mechanism 17 may further include second fastener 174, and second fastener 174 may be attached to an end of elongated portion 1712 distal from fixed portion 1711. In practical applications, the second fastening member 174 can be used to limit the movement of the connecting member 173, so as to prevent the connecting member 173 from being ejected from the side of the extending portion 1712 away from the fixing portion 1711, thereby improving the safety of the elastic connection mechanism 17.
For example, the second fastener 174 may include at least one of a bolt, a screw and a stud, and the embodiments of the present application may not be limited to the specific contents of the second fastener 174.
Optionally, the connecting member 173 may specifically include a first limiting portion 1731 and a second limiting portion 1732 arranged at a preset included angle, and a clamping groove 1733 for clamping the frame 21 is formed between the first limiting portion 1731 and the second limiting portion 1732; the first limiting portion 1731 may be used to abut against the outer surface of the frame 21 of the to-be-tested frame 21 assembly to limit the thickness of the to-be-tested photovoltaic assembly 20, and the second limiting portion 1732 at least partially extends into the frame 21 to limit the length of the bracket 10.
