Signal terminal modules and connectors

Abstract

This invention discloses a signal terminal module, a connector module, and a connector. The signal terminal module includes: a signal terminal having a first fixing portion and a first elastic arm connected to the first fixing portion; and a conductive sheet attached to the first elastic arm of the signal terminal. The first elastic arm has a first electrical contact portion located at its end for electrical contact with a mating board, and the conductive sheet is used to adjust the contact impedance of the first electrical contact portion of the signal terminal. In this invention, the conductive sheet attached to the elastic arm of the signal terminal can adjust the contact impedance of the electrical contact portion of the elastic arm, such that the contact impedance of the electrical contact portion of the elastic arm is equal to or approximately equal to the designed nominal impedance, thereby improving the signal integrity of the signal transmission path.
