Description

Cable connector combination

The present invention relates to a cable connector assembly, and more particularly to a cable connector combination having a wire connected to a conductive terminal.

In a common cable connector combination, due to its own structure, the cable connector combination will generate impedance and affect the transmission quality of the signal. How to overcome or reduce the impact of impedance is a problem that must be solved.

A conventional cable connector assembly includes an insulative housing, a conductive terminal housed in the insulative housing, and a cable having a lead. The conductive terminal has an abutting portion that is opposite to the mating connector assembly, a welded portion that is welded to the lead wire, and a connecting portion between the abutting portion and the welded portion. Wherein, the thickness of the abutting portion, the connecting portion and the welded portion of the general conductive terminal are substantially the same. When the wire is welded to the welded portion, the thickest dimension (A) of the conductive signal conductor at the welded portion is the sum of the thickness of the welded portion, the diameter of the wire, and the thickness of the solder. When the cable connector assembly is mated with the mating connector assembly, the thickest dimension (B) of the conductive signal conductor at the mating portion of the conductive terminal is the sum of the mating portions of the two connector conductive terminals. At this time, the A size and the B size are much larger than the thickness of the joint. If, in the signal transmission process, the thickness of the conductive signal conductor suddenly changes, and the other factors affecting the impedance data, such as the dielectric constant, the diameter of the wire, and the thickness of the conductive terminal, cannot be effectively compensated, during the transmission of the data, the cable connection The combination of the device will have a relatively obvious impedance mutation, which affects the transmission quality.
