Problems solved by technology

There will be a length difference between the high-speed line pairs C1, C2, and C3, resulting in an inter-pair delay difference (Inter-pair Skew) between multiple differential pairs, which also affects the characteristics of data transmission
[0004] Therefore, how to improve the design of the cable structure to avoid the delay difference (Skew) between multiple cables from affecting the characteristics of high-frequency signals, and even causing data errors in transmission

The insulating material is used for wrapping the at least one cable assembly and the at least one transmission line.

Description

technical field [0001] The invention relates to a cable structure, in particular to a high-speed transmission cable and a wire end connector with the high-speed transmission cable. Background technique [0002] Such as figure 1 as shown, figure 1 It is a schematic diagram of a high-speed transmission cable in the prior art. In the prior art, twisted cables are used to offset the magnetic field effect generated by the cables and reduce the problem of transmission signal attenuation caused by crosstalk. Depend on figure 1 It can be seen that when two high-speed wires are twisted together, the high-speed wire pair (such as figure 1 The arrangement of L1, L2) will be uncontrolled, which makes it necessary to adjust the position of the high-speed line when the high-speed line pair is connected to the solder pad on the circuit board. This will cause the length mismatch of the high-speed line pair, resulting in the differential intra-pair skew (Intra-pair skew) between the dif...
