It is divided into collector ribbon and interconnection strip. It is used to connect the cells of photovoltaic modules and plays an important role in conducting electricity. The welding ribbon is an important raw material in the welding process of photovoltaic modules. The quality of the welding ribbon will directly affect the current collection efficiency of the photovoltaic module and have a great impact on the power of the photovoltaic module.

[0003] In the existing patent application number 202121928441.X, "a high-performance round wire photovoltaic welding strip" is disclosed, including a device main body and a first welding block, a first oblique block is fixedly connected to one side of the device main body, and a first welding block is fixedly connected to one side of the first oblique block. A welding mechanism is fixedly installed inside the first welding block, and the welding mechanism includes a flux coating, a wear-resistant layer, a thermal insulation film and an insulating layer. However, the connection method set in this application is only to connect a raised square block of the connecting head to the groove of the connecting port. This connection method is likely to cause gaps at the connection, which is not compact enough, resulting in leakage, serious damage to others, low safety, and the setting is not conducive to extending its service life.

[0004] Therefore, it is necessary to design a photovoltaic welding ribbon with strong practicality and stable connection. Utility Model Content

When the top end of the connecting rod 11 is in contact with the copper body 7, the connecting rod 11 is fixedly connected to the copper body 7. When the copper body 7 is in contact, the operator rotates the connecting rod 11 to drive the cam locking ring 12 to rotate 90°, so that it engages with the card slot inside the docking slot 6. At this time, the end face of the docking slot 6 and the end face of the connecting port 9 are closely fitted together.
