In the embodiment of the application, the support 10 may be used to be installed on the photovoltaic module 20 to be tested, and the test fixture is fixed on the photovoltaic module 20 to be tested. 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.

Specifically, the bracket 10 may be used as a structural body of the test fixture, and may be used to support the fixture body 11, the first connector 12, and the electrical cable 13.

Specifically, the support 10 is a tubular support, the inside of the support 10 is provided with a containing cavity for containing the electric cable 13, and the electric cable 13 is arranged in the containing cavity to prevent the electric cable 13 from being exposed. Therefore, the test tool is installed in the process of the photovoltaic module 20 to be tested, or in the process of testing the performance of the photovoltaic module 20 to be tested. Since the exposure of the electric wire 13 is avoided. 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.

Alternatively, the first connector 12 is fixedly connected to the bracket 10 to securely fix the first connector 12 to the bracket 10. Since the first connector 12 is fixedly connected to the bracket 10, after the test fixture is mounted on the photovoltaic module 20 to be tested, the position of the first connector 12 is fixed and can be easily positioned. Therefore, automatic alignment and connection between the first connector 12 and the second connector 22 can be realized, and the test efficiency of the test tool for testing the photovoltaic module 20 to be tested is improved. Moreover, the fixed connection can prevent the first connector 12 from shaking on the bracket 10, and further improve the positioning accuracy of the first connector 12.

Referring to fig. 5, a schematic structural view of a stent according to an embodiment of the present application is shown, and referring to fig. 6, a schematic structural view of another angle of the stent shown in fig. 5 is shown. As shown in fig. 5 and 6, the bracket 10 is provided with a first connecting groove 102 for connecting the first connector 12, and the first connecting groove 102 is communicated with the accommodating cavity; a second end of the electric cable 13 protrudes from the first connection groove 102 and is electrically connected with the first connector 12; the first connector 12 is at least partially located outside the first connection slot 102, and the first connector 12 can slide along the first connection slot 102. Therefore, the electric cable 13 can be completely bound in the accommodating cavity of the bracket 10, the electric cable 13 is further prevented from being exposed, and the electric cable 13 is prevented from impacting the surface of the photovoltaic module 20 to be tested. Moreover, the position of the first connector 12 on the support 10 is adjusted by sliding the first connector 12 along the first connecting groove 102 to adapt to the photovoltaic module 20 to be tested with different sizes.

Moreover, since the first connector 12 can be locked on the first connection groove 102 by the first fastening member 15, on the one hand, the relative position between the first connector 12 and the tool main body 11 can be locked, and the automatic alignment and connection between the first connector 12 and the second connector 22 can be facilitated. On the other hand, the first connector 12 is prevented from sliding during the test process, and the connection reliability between the first connector 12 and the second connector 22 is improved.

The number of the through holes can be matched with the number of the first fastening pieces 15, and the number of the first fastening pieces 15 can be set according to actual installation requirements. In the drawings of the embodiments of the present application, only the case that the number of the first fastening members 15 is 2 is shown, but in practical applications, the number of the first fastening members 15 may also be 1, 4, or 6, and the like, and the embodiments of the present application do not specifically limit the number of the first fastening members 15.

In the embodiment of the application, the bracket 10 is further provided with a tool bracket 101 for connecting the tool main body 11, and the tool bracket 101 is provided with a first mounting hole 1011 communicated with the accommodating cavity; the first end of the electric cable 13 extends from the first mounting hole 1011 and is electrically connected to the tool main body 11. Therefore, the electric cable 13 can be completely bound in the accommodating cavity of the bracket 10, and only one end of the electric cable 13 extends out of the first mounting hole 1011 to be electrically connected with the tool main body 11, so that the electric cable 13 is further prevented from being exposed, and the electric cable 13 is prevented from impacting the surface of the photovoltaic module 20 to be tested.

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.

For example, the elastic member 172 may include, but is not limited to, a spring plate, and the like, and the specific content of the elastic member 172 may not be limited in the embodiments of the present application.

Alternatively, as shown in fig. 5, the end of the bracket 10 is provided with a second mounting hole 103; as shown in fig. 8 and 9, the connecting body 171 may specifically include a fixing portion 1711 and an extending portion 1712, wherein the fixing portion 1711 is at least partially embedded in the second mounting hole 103 to fix the connecting body 171 at the end of the bracket 10; the length direction of the extension portion 1712 is parallel to the length direction of the support 10, and the elastic member 172 is sleeved on the extension portion 1712 and can extend and contract along the length direction of the extension portion 1712, so as to adjust the length of the elastic connection mechanism 17 in the length direction of the support 10.

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.

Referring to fig. 10, a schematic diagram of a connection state between a connection piece and a photovoltaic module to be tested according to an embodiment of the present application is shown. In a specific application, in the process of installing the test fixture to the to-be-tested photovoltaic module 20, the first limiting portion 1731 may be abutted against the C-surface of the frame 21 to limit the movement of the connecting member 173 along the thickness direction of the to-be-tested photovoltaic module 20. Then, the elastic member 172 is released, so that the second limiting portion 1732 extends into the frame 21 and abuts against the frame 21 under the automatic restoring force of the elastic member 172, so as to limit the movement of the connecting member 173 along the length direction of the bracket 10. Because the clamping groove 1733 is formed between the first limiting portion 1731 and the second limiting portion 1732, the clamping groove 1733 can be clamped with the frame 21 to further limit the movement of the connecting member 173 along the thickness direction of the photovoltaic module 20 to be measured and the length direction of the bracket 10, and improve the connection reliability of the connecting member 173 and the frame 21. Therefore, the installation reliability of the test tool on the photovoltaic module 20 to be tested can be further improved.

It should be noted that, under the limiting action of the first limiting portion 1731 and the second limiting portion 1732, the connecting member 173 is only connected to the frame 21 of the photovoltaic module 20 to be tested and is not in contact with the back of the photovoltaic module 20 to be tested, so that the connecting member 173 is prevented from being in contact with the back of the photovoltaic module 20 to be tested, and the photovoltaic module 20 to be tested is prevented from being damaged.

Specifically, the first limiting portion 1731 may be used to limit the movement of the connecting member 173 along the thickness direction of the photovoltaic module 20 to be tested. Therefore, by setting the height of the first limiting portion 1731, the distance between the first connector 12 and the back of the photovoltaic module 20 to be tested can be controlled, so that the photovoltaic module 20 to be tested is prevented from being damaged by the back contact of the first connector 12 and the back of the photovoltaic module 20 to be tested, and the use safety of the test tool is improved.

In practical applications, by designing the height of the first limiting portion 1731, etc., when the first limiting portion 1731 abuts against the outer surface of the to-be-tested photovoltaic module 20 perpendicular to the height direction, a gap may be formed between the first connector 12 and the back surface of the to-be-tested photovoltaic module 20, so as to prevent the first connector 12 from contacting the back surface of the to-be-tested photovoltaic module 20.

For example, the width of the gap may be 5 mm, 8 mm, 10 mm, or the like, and the width of the gap is not specifically limited in the embodiments of the present application. To sum up, the test fixture in the embodiment of the present application can at least include the following advantages:
