The diameters of the first wire core 31, the second wire core 32, the third wire core 33, the fourth wire core 34, and the fifth wire core 35 are the same.

Since all cores have the same diameter, they have similar resistance, inductance and transmission characteristics, which means that the performance between the different cores is uniform, both in terms of signal transmission and circuit connection, and can be managed and maintained more easily; the cores of the same diameter can generally be used interchangeably, which increases flexibility and convenience; the wire cores with the same diameter simplify the design and installation of the wire harness, and reduce the management and matching requirements for different wire core sizes. This reduces the potential risk of misconnection; the same diameter core may ensure uniformity of performance of the various portions within the wiring harness, whether in terms of current capacity, signaling, or other electrical properties, thereby providing a more reliable circuit connection.
