As shown in Figures 1 to 3, the utility model discloses a photovoltaic connector testing device 100, which includes a casing 10, two test joints 20 extending outward from the casing 10, and a The connection line 30 inside and connects the two test connectors 20 .

The two test connectors 20 respectively extend from the same side of the casing 10 and are used to connect two photovoltaic connectors 200 respectively, such as pins and sockets representing positive and negative poles respectively. The two test connectors 20 A display screen 40 is also arranged between them. As shown in FIG. 3 , the test joint 20 includes a contact head cover 21 installed on the surface of the casing 10, a test terminal 22 located in the contact head cover 21, and a test terminal 22 located on the rear side of the test terminal 22 and extending into the machine.
