Embodiment Construction

[0019] Embodiments presented herein include various pluggable electrical connectors (referred to herein as pluggable connectors) configured for data signal communication. Embodiments may also include a cable assembly or interconnection system for the pluggable connector. The pluggable connector is configured to mate with a corresponding mating connector, such as a receptacle connector in a receptacle assembly. The pluggable connector has signal contacts and ground contacts configured to engage corresponding contacts of the mating connector. The pluggable connector also includes at least one ground plate and a plurality of resonance control plates. The resonance control blade electrically interconnects the ground contacts of the pluggable connector to the ground plate, thereby electrically commoning the ground contacts. To this end, the resonance control plate optionally includes one or more edge protrusions that engage the ground plate and / or corresponding ground contacts. ...

Abstract

Pluggable connector (102) includes a module body (114) having a mating plug (116) that is configured to be inserted into a receptacle assembly during a mating operation. The mating plug has first and second plug sides (122, 124) that face in opposite directions and a front edge (126) that joins the first and second plug sides. The pluggable connector also includes a plurality of signal contacts (130) that are positioned along the first and second plug sides and a ground plate disposed within the mating plug. The ground plate (150) is positioned between the signal contacts along the first plug side and the signal contacts along the second plug side. The pluggable connector also includes a plurality of resonance-control blades (152) disposed within the mating plug and extending between the ground plate and at least one of the first plug side or the second plug side. The resonance-control blades have edge projections (212) that engage the ground plate.

Description

technical field [0001] The present invention relates to a pluggable connector having signal contacts configured to carry data signals, and ground contacts to control impedance and reduce crosstalk between the signal contacts. Background technique [0002] Communication systems exist today that utilize pluggable cable assemblies to transmit data. For example, network systems, servers, data centers, etc. may use many cable assemblies to interconnect various devices in a communication system. The cable assembly may include a pluggable connector configured to be inserted into the receptacle assembly. The pluggable connector includes signal contacts that transmit data signals and ground contacts that control impedance and reduce crosstalk between the signal contacts. In differential signaling applications, the signal contacts are arranged in signal pairs for carrying data signals. Each signal pair may be separated from adjacent signal pairs by one or more ground contacts. [...
