Mass spectrometers are a class of precision instruments that are capable of analyzing the composition of a sample. Triple quadrupole mass spectrometers are widely used for their excellent quantitative analysis capabilities and small size. The main principle is that voltage scanning is applied to a quadrupole rod, and ions with different mass-to-charge ratios are screened through different voltages. The peak-to-peak voltage applied to the quadrupole rods can be in the thousands of volts, and with improved performance, the voltage will be higher. An ion optical system in the mass spectrometer is placed in a vacuum cavity, a power supply and a circuit board are placed under atmospheric pressure and are electrically connected with the interior of the vacuum cavity through a special electrode, and the vacuum cavity is designed to be compact in order to ensure the overall size of the mass spectrometer and the vacuum degree, so that extremely high requirements are provided for a feed lead in the ion optical system. The wire is arranged in a narrow space, the phenomenon that discharge occurs when the distance is too close to each other is avoided, meanwhile, the wire is kept compact, bending with multiple dimensions is basically needed, and some places even need to be bent into an arc shape.
