In this embodiment, the test connectors are a male connector and a female connector of MC4 series, which are respectively coupled with the female connector and the male connector of MC4 series on the solar cell module 1 to be tested; selecting a cylinder as the piston device 7; the control mechanism 4 consists of a PLC, an electromagnetic valve, an air compressor and a switching power supply, the switching power supply supplies power to the PLC and the electromagnetic valve, and the PLC is respectively and electrically connected with the electromagnetic valve, the alarm device 5, the control terminal 3 and the in-place sensor 6; the air compressor provides compressed air for the piston device 7 through the electromagnetic valve to serve as power, the electromagnetic valve is connected with the piston device 7 through the two air pipes, and the piston device 7 responds when the electromagnetic valve opens an air passage switch of one air pipe (meanwhile, an air passage of the other air pipe is closed); when the same piston device 7 is reset, the electromagnetic valve opens the air passage switch of one air pipe which is opposite to the response of the piston device 7 (meanwhile, the air passage of the other air pipe is closed); in this embodiment, an LTA-205 multi-layer audible and visual alarm is selected as the alarm device 5.
In the embodiment, the joint clamp 9 has two clamping portions 12, as shown in fig. 2, for fixing two test joints, respectively, in use, the test joints are installed in the corresponding clamping portions 12, and then the two bolts 11 at the center are tightened to make the upper portion and the lower portion of the joint clamp 9 close to each other, thereby achieving the purpose of clamping the test joints; the joint clamp 9 is connected to the piston device 7 through the mounting hole 14 by a bolt 11. When the anti-drop structure is used, if the test connector is provided with the anti-drop structure, the anti-drop structure is dismantled and damaged so as to ensure that the to-be-tested connector and the test connector can be smoothly separated after the test is finished. As shown in fig. 3, the connector holder 13 in this embodiment is configured such that four concave card slots are disposed on the base perpendicular to the connector holder, and the longitudinal sections of the four card slots are respectively the same as the longitudinal sections of two ends of two connectors to be tested on the solar cell module 1 to be tested, so that the two connectors to be tested are firmly fixed by the concave card slots.

the test result of the electric correlation test is analyzed and judged on the computer system, if the test result does not meet the requirement, the computer system sends an error signal; after receiving the error signal, the control mechanism 4 controls the piston device 7 to respond, so that the test connector is coupled with the connector to be tested, and the electrical correlation test is performed again.
After the retest, if the control mechanism 4 still receives the error signal, the alarm device 5 is triggered and the discharging is stopped;
if the control mechanism 4 does not receive the error signal after the retest, the solar cell module 1 discharges.
Example two
On the basis of the first embodiment, the connector holder 13 in the present embodiment and the junction box 15 on the solar cell module 1 to be tested are integrally formed at the same time, and the connector holder 13 is W-shaped and includes two grooves; the shape of the longitudinal section of the groove is the same as that of the longitudinal section of the to-be-tested connector of the to-be-tested solar cell module 1, so that the two to-be-tested connectors are stably fixed by the groove. The joint clamping seat 13 and the junction box 15 are integrally formed, so that when the junction box 15 is assembled on the assembly line 10, the joint to be tested of the solar cell module 1 can be directly pressed into the joint clamping seat 13, thereby saving manpower and stations and obviously benefiting more.
It is obvious to those skilled in the art that the structure of the connector holder 13 can be rearranged according to the present disclosure, such as separating the two clamping portions 12, which are respectively disposed at the left and right sides of the terminal box 15, but this should not be beyond the scope of the present disclosure.
