High density electrical connector adaptable to the wires of different diameters and the method of making the same

摘要

A high-density electrical connector for electrically connecting a mating electrical connector is equipped with two stepped transmission boards. Each of the transmission boards forms a plurality of first conductive regions and second conductive regions alternatively arranged thereon in different rows and pitches. The first conductive regions are alternatively arranged in a first row in a first pitch for respectively electrically connecting the corresponding terminals. The second conductive regions are alternatively arranged in a second row in a second pitch wider than the first pitch for selectively electrically connecting with the wires of different diameters. Understandably, the second pitch is sufficient to keep spacing each two adjacent wires away from each other, particularly to other wider wires. A plurality of circuit traces build an electrical connecting path between the relative first and second conductive regions.
