Connectors and mating connectors

Abstract

This invention discloses a connector and a mating connector. The connector includes: an insulating shell including a peripheral wall and a bottom wall forming an inner cavity, and a retainer connected to the peripheral wall and / or the bottom wall; a plurality of terminal modules mounted in the inner cavity of the insulating shell, each terminal module including multiple pairs of high-speed signal terminals; and a plurality of low-speed signal terminals held on the retainer for electrical contact with the low-speed mating signal terminals of the mating connector. The retainer guides the connector to mate with the mating connector. The retainer of this invention not only holds the low-speed signal terminals but also guides the connector and the mating connector to mate, thereby simplifying the connector structure and reducing the connector size. Furthermore, the layout of the high-speed and low-speed signal terminals of this invention optimizes the impedance consistency of the signal transmission path, meeting higher signal transmission rates and lower mating height requirements.
