In this embodiment, the bending radius of the FPC60 to be tested can be changed by replacing the adjusting lever 41 with different thickness. The purpose of changing the bending radius is to verify the FPC performance and the service life in a non-use scene, so as to provide guidance for the structural design of a product. In the embodiment, the thickness of the adjusting rod 41 is adjusted to test the FPC60 at different bending radii.
In addition, during assembly, it should be ensured that the second clamping assembly 20 uses the position of the adjusting lever 41 as a rotating shaft, that is, the rotating shaft of the rotating arm and the adjusting lever 41 are overlapped, so as to avoid bending or tightening damage of the FPC60 during bending. Therefore, in this embodiment, the escape opening 421 is opened at the position of the rotation axis of the rotation arm 42 for the adjustment rod 41 to pass through.

The counter is used to record the number of times the rotating assembly 40 rotates back and forth, for example, the sequence of the back and forth movement of the rotating assembly 40 is recorded. After the FPC60 is connected to the electrical module, the electrical parameters, such as the dc impedance, of each signal line inside the FPC60 can be measured in real time, and the open circuit of the FPC60 can be detected at all times. And once the internal signal line is broken, the FPC bending service life and electrical performance detection device stops testing. In addition, the detection module further comprises an alarm module, the alarm module is electrically connected with the electrical module, and when the electrical module detects that the internal signal line is broken, the alarm module gives a prompt by lighting and buzzing.
