Flexible electrodes are widely applied to many fields such as sensor, flexible printed circuit board, photovoltaic cell, cell phone, digital camera, and liquid crystal display and so on. Aim at the connecting problem between flexible electrodes and external wires; the detachable clamping connection was firstly brought forward to solve the aim problem under normal temperature. And on the basis of such idea, the corresponding clamper was designed and fabricated further by mechanical procedures. Then verifying and comparing experiments were done and observed. Experiment results illustrate that the detachable clamping connection is correct and effective and that such connection could solve the aiming problem without high temperature welding procedure. And furthermore it’s also known that clamper doesn’t change the main characteristics of signal transmission. The detachable clamping connection is very useful and effective for the connection between flexible thin film conductor and common wires when they can not be directly welded together under high temperature.
