AI Technical Summary

Technical Problem

When existing electrical plug-in connectors are used for differential signal transmission in radio frequency technology, they have high manufacturing costs and their asymmetrical structure affects electromagnetic compatibility and signal-to-noise ratio, making it difficult to meet the high data rate requirements in economical mass production.

Method used

The asymmetry of the inner conductor contact element relative to the longitudinal axis is compensated by setting a compensating geometry in the outer conductor contact element and the dielectric, and the impedance of the asymmetric transmission system is matched. The compensating geometry is determined using simulation and iterative optimization methods.

Benefits of technology

Stable differential signal transmission under asymmetric structure was achieved, improving electromagnetic compatibility and signal-to-noise ratio, simplifying the manufacturing process, and reducing costs.

Abstract

This invention relates to an electrical plug-in connector and a method for manufacturing an electrical plug-in connector. The electrical plug-in connector for differential signal transmission has an outer conductor contact element, a dielectric, and at least one pair of inner conductor contact elements for differential signal transmission. The dielectric extends through the outer conductor contact element along a longitudinal axis. The pair of inner conductor contact elements has a first inner conductor contact element and a second inner conductor contact element, which extend through the dielectric along the longitudinal axis. The outer conductor contact element and / or the dielectric has a compensating geometry to compensate for asymmetry of the inner conductor contact element pair relative to the longitudinal axis. Alternatively or additionally, the inner conductor contact element pair has a compensating geometry to compensate for asymmetry of the outer conductor contact element and / or the dielectric relative to the longitudinal axis.
