Problems solved by technology

However, the altered shape of the inner traces distorts the differential signal, causing unwanted mode conversion of some differential-mode signals into common-mode signals
Specifically, differential traces that change shape have the disadvantage of causing differential-to-common-mode conversion

Embodiment Construction

[0021] like figure 1 As shown in , the cable harness 10 according to the embodiment of the present invention includes a connector assembly 700 and a cable 600 as a second connection object 600 . although figure 1 The cable 600 shown in is simply shown as a plurality of insulated single wires, but in reality, the cable 600 is a multi-core cable. Specifically, in practice, the cable 600 includes a plurality of insulated single wires bundled together, and a sheath covering the bundled insulated single wires.

[0022] like figure 1 As shown in , the connector assembly 700 of this embodiment includes a connector 500 and a circuit board 100 as the first connection object 500 .

[0023] refer to figure 1 , the connector 500 of this embodiment can be mated with a mating connector (not shown) along the mating direction. In this embodiment, the mating direction is the X direction. like figure 1 As shown in , the connector 500 of this embodiment includes a plurality of termin...

Abstract

The invention provides a circuit board, a connector assembly and a cable harness. The circuit board is used for electrically connecting between a first connecting object and a second connecting object. The circuit board comprises at least a first wiring layer, a second wiring layer and a via hole. The first wiring layer is formed with a pair of first ends, a pair of second ends, a coupling portion, a pair of first trace portions and a pair of second trace portions. The coupling portion has a pair of first coupling points, a pair of second coupling points, an inner trace portion, an outer traceportion and a ground conductor portion. The inner trace portion has a length equal to a length of the outer trace portion. The ground conductor portion is arranged between the inner trace portion andthe outer trace portion. The second wiring layer is formed with a ground pattern. The ground conductor portion is connected with the ground pattern through the via hole.

Description

technical field [0001] The present invention relates to circuit boards, connector assemblies and cable harnesses. Background technique [0002] refer to Figure 7 , Japanese Patent Application Laid-Open No. 2004-14800 (Patent Document 1) discloses a circuit board 900 on which differential trace pairs 920 are formed. The differential trace pair 920 has a pair of first trace portions 921 , a pair of second trace portions 928 and a junction portion 930 . The first trace part 921, the joint part 930 and the second trace part 928 are joined in this order. The coupling portion 930 has a pair of first coupling portions 932 , a pair of third trace portions 933 , a pair of through holes 934 , a pair of fourth trace portions 936 and a pair of second coupling portions 937 . The coupling part 930 is configured such that the first coupling part 932 , the third trace part 933 , the through hole 934 , the fourth trace part 936 and the second coupling part 937 are coupled in this order. ...
