Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic cells, in particular to a probe row fixing device. Background Art

[0002] Currently, the method for testing solar cells is to contact the metal probes on the probe row with the main grid lines printed on the surface of the solar cell, and inject current from the main grid lines into the solar cell through the probes, thereby achieving the purpose of testing the solar cell.

[0003] As the number of main grids of existing photovoltaic cell products increases, the arrangement of probe rows becomes more and more compact. The traditional way to fix probe rows is to fix each probe row to the corresponding device with a separate screw. However, as the number of probe rows increases, the number of fixing screws increases, and the screws are prone to stripping and loosening. The probe rows are also prone to deformation due to uneven force. This fixing method also requires a special short-handled hexagonal tool. Due to the limited operating space, it is even more inconvenient to use screws to install the increased number of probe rows in a limited space.

[0004] Therefore, the disadvantages of the existing probe row fixing method are becoming increasingly obvious. In view of this, this patent application is proposed. Utility Model Content
