Abstract
Description
- The subject matter herein relates generally to stacked receptacle connector assemblies.
- Some communication systems utilize communication connectors to interconnect various components of the system for data communication. Some known communication systems use pluggable modules, such as I/O modules, that are electrically connected to the communication connector. Conventional communication systems have performance problems, particularly when transmitting at high data rates. Known communication systems provide electrical shielding, such as in the form of a receptacle cage surrounding a communication connector and the pluggable module to provide electrical shielding. However, assembly of such communication systems is problematic. For example, the communication connector typical of a stacked receptacle cage includes two sets of contacts, an upper contact set and a lower contact set, both terminated to the circuit board. The upper contact set mates with the upper pluggable module and the lower contact set mates with the lower pluggable module. However, the upper contact set uses long contacts that are susceptible to damage during termination to the circuit board and experience signal degradation due to the long signal paths. Additionally, the contacts of the upper set are shaped differently than the contacts of the lower set, leading to additional design and manufacturing costs.
- A need remains for a communication system that may be assembled in a cost effective and reliable manner.
- In an embodiment, a stacked receptacle connector assembly is provided including a receptacle cage configured to be mounted to a circuit board, a lower communication connector assembly received in the receptacle cage, and an upper communication connector assembly stacked in the receptacle cage above the lower communication connector assembly.

The upper communication connector assembly includes a paddle card, an upper communication connector mounted to the paddle card, and a cable assembly having cables electrically connected to the paddle card and extending from the paddle card. The paddle card is received in the cavity at the rear such that the upper communication connector is aligned with the upper module channel for mating with the upper pluggable module. The upper communication connector has an upper housing having an upper card slot holding upper contacts within the upper card slot for electrical connection with the upper pluggable module. The upper contacts are coupled to the paddle card and the cables extend rearward from the receptacle cage remote from the receptacle cage.
