A capacitor structure comprises: a first plate structure and a second plate structure, the first plate structure and the second plate structure are plate structures of the same structure, the plate structure comprises: a plurality of sub-structures; the sub-structure comprises: a first metal segment and a second metal segment located in the same layer; a third metal segment and a fourth metal segment located in the same layer; a first via; a second via; a third via; the plate structure further comprises: a connecting metal segment, the connecting metal segment is electrically connected with the plurality of sub-units, and the midpoint position of the connecting metal segment along the extension direction is suitable for an input signal. The plate structure comprises a plurality of sub-structures, the plurality of sub-structures are electrically connected through the connecting metal segment; the key position of the connecting metal segment along the extension direction is suitable for the input signal, the difference in the length of the signal channel can be effectively shortened to reduce the difference in the pressure drop, and the capacitance value and the Q value of the capacitor structure formed can be effectively improved.

This invention belongs to the field of copper wire cutting technology for cables, specifically disclosing a copper wire cutting processing device for cables, including a worktable. A feeding protection box is connected to one side of the upper end of the worktable, and a conveying box is connected to one side of the feeding protection box. A cutting protection box is connected to the end of the conveying box away from the feeding protection box. A feeding mechanism is connected to one side of the upper end of the worktable, located inside the feeding protection box. A detanglement mechanism is connected to one side inside the conveying box. This invention, through the coordinated design of the feeding mechanism, the detanglement mechanism, and the tightening mechanism, performs local pre-twisting of the copper wire before cutting, straightens the twist direction, and weakens local torsional stress, effectively suppressing end-spreading and wire bridging during cutting, ensuring consistent cut length and neat cuts, and improving cutting quality and production efficiency.
