Coaxial cable processing method

The present invention relates to a method for processing a coaxial cable (60) for applying a voltage to a time-of-flight mass spectrometer (10), the method comprising a turn-back processing step (S2) and an embedding processing step (S3). In the folding-back processing step (S2), a folded-back portion (66a) is formed by folding back the tip portion of a shielded wire (66) toward the outer sheath (68) side with respect to a coaxial cable (60) having a center conductor (62), an insulator (64) provided around the center conductor (62), the shielded wire (66) provided around the insulator (64), and the outer sheath (68) provided around the shielded wire (66). In the embedding process step (S3), an insulating or semi-conductive embedded member (74) is disposed in a gap (72) formed between the folded-back portion (66a) and the insulator (64). 本发明涉及用于对飞行时间型质量分析装置(10)施加电压的同轴电缆(60)的处理方法，包括折回处理工序(S2)和埋设处理工序(S3)。在折回处理工序(S2)中，对于同轴电缆(60)，通过将屏蔽线(66)的顶端部向外部护套(68)侧折回而形成折回部(66a)，同轴电缆具有中心导体(62)、设置于中心导体(62)的周围的绝缘体(64)、设置于绝缘体(64
