Terminal modules, connectors, mating terminal modules and mating connectors

Abstract

This invention discloses a terminal module, a connector, a mating terminal module, and a mating connector. The terminal module includes: an insulator; a pair of grounding members fixed to the insulator and spaced apart from each other in the width direction of the insulator; and multiple pairs of high-speed signal terminals fixed to the insulator and arranged in a row in the length direction of the insulator. The multiple pairs of high-speed signal terminals are located between the pair of grounding members and spaced apart from the grounding members by a predetermined distance in the width direction. Each grounding member includes multiple grounding springs corresponding to each of the multiple pairs of high-speed signal terminals, and the multiple grounding springs are arranged in a row in the length direction of the insulator. Each high-speed signal terminal has a contact spring arm, and the contact spring arm of each pair of high-speed signal terminals is located between a corresponding pair of grounding springs facing each other in the width direction. This invention can effectively suppress resonance and noise coupling between adjacent pairs of high-speed signal terminals, reducing signal crosstalk.
