technical field [0001] The invention relates to a conductive structure, in particular to a movable conductive structure used for electrodes of a seam welding machine. Background technique [0002] The active conductive structure of the current transmission of the electrode shaft and the electrode seat used in the AC, inverter, and rectifying seam welding machines is as follows: figure 1 , figure 2 shown. [0003] The movable conductive structure of the electrode shaft and the electrode holder inside the electrode of the traditional seam welding machine, the conduction method is to compress the electrode holder through a spring, so that the tapered surface of the electrode shaft and the electrode holder are attached to conduct electricity, such as figure 1 As shown, in order to achieve low rotational resistance and strong electrical conductivity in this structural form, it is first necessary to ensure the matching accuracy between the electrode seat 80, the electrode tile ...

Problems solved by technology

In this conductive structure, the electrode seat uses a spring 96 to press the electrode tile, and the pressure of the spring presses the electrode tile 93 to the electrode shaft. Due to the friction force generated between the electrode shaft and the electrode tile and the electrode seat during the rotation process, The pressing block 95 of the electrode seat pressing the motor tile is only connected by the spring 96 and the soft copper strip 98, and the pressing block 95 is easy to pry, which leads to the situation that sometimes the conductive area decreases and sometimes the conductive area increases, resulting in unstable conductivity

When the seam welding machine is frequently energized and welded, under the action of high current, the entire circuit generates a strong magnetic field, which affects the energization effect, and the structure also determines that the size of the electrode holder cannot be miniaturized.
