As an alternative embodiment, as shown in fig. 1, each rf pad 2 is connected in series with a capacitor 4.
In this embodiment, since the two ends of each radio frequency line 1 are respectively provided with the radio frequency seats 2, and each radio frequency seat 2 is connected with one capacitor 4 in series, the capacitors 4 can play a role in blocking, thereby improving the detection efficiency of the device for detecting the buckling of the radio frequency lines.
