Technical Field

The subject matter herein relates generally to receptacle assemblies.

Background

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 connectors. Conventional communication systems suffer from performance problems, particularly when transmitting at high data rates. Known communication systems provide electrical shielding, for example in the form of a receptacle cage that provides electrical shielding around the communication connector and the pluggable module. However, the components of such communication systems are problematic. For example, a communication connector is typically press-fit to a circuit board using a receptacle cage during a single press-fit operation. In such systems, routing of the light pipes is difficult and may block airflow through the system.

There remains a need for a communication system that can be assembled in a cost effective and reliable manner.

Detailed Description

Fig. 1 is a front perspective view of a communication system 100 formed in accordance with an exemplary embodiment. Fig. 2 is a rear perspective view of a communication system 100 formed in accordance with an exemplary embodiment. The communication system includes a circuit board 102 and a receptacle connector assembly 104 mounted to the circuit board 102. The pluggable module 106 is configured to electrically connect to the receptacle connector assembly 104. The pluggable module 106 is electrically connected to the circuit board 102 through the receptacle connector assembly 104.

In an exemplary embodiment, the receptacle connector assembly 104 includes a receptacle cage 110 and a communication connector 112 (also shown in fig. 3 and 4) adjacent the receptacle cage 110. For example, in the illustrated embodiment, the communication connector 112 is received in the receptacle cage 110. In other various embodiments, the communication connector 112 may be located behind the receptacle cage 110. In various embodiments, the receptacle cage 110 is enclosed and provides electrical shielding for the communication connector 112. The pluggable modules 106 are loaded into the receptacle cage 110 and are at least partially surrounded by the receptacle cage 110. The receptacle cage 110 includes a plurality of walls 114 that define one or more module channels for receiving corresponding pluggable modules 106. The wall 114 may be a wall defined by a solid sheet, a perforated wall that allows airflow therethrough, a wall with a cutout (e.g., for a heat sink or heat spreader to pass therethrough), or a wall defined by a rail or beam with a relatively large opening (e.g., for airflow therethrough). In an exemplary embodiment, the receptacle cage 110 is a shielded, stamped cage member, wherein the wall 114 is a shielding wall. In other embodiments, the receptacle cage 110 may be open between frame members (e.g., rails or beams) to provide cooling airflow for the pluggable modules 106, wherein the frame members of the receptacle cage 110 define guide rails for guiding the loading of the pluggable modules 106 into the receptacle cage 110.

In the illustrated embodiment, the receptacle cage 110 constitutes a stacked cage member having an upper module passage 116 and a lower module passage 118. The receptacle cage 110 has module ports that lead to module channels 116, 118 that receive the pluggable module 106. Any number of module channels may be provided in various embodiments. In the illustrated embodiment, the receptacle cage 110 includes upper and lower module channels 116, 118 arranged in a single column, however, in alternative embodiments, the receptacle cage 110 may include multiple columns of ganged module channels 116, 118 (e.g., 2X2, 3X2, 4X2, 4X3, etc.). The receptacle connector assembly 104 is configured to mate with the pluggable module 106 in two stacked module channels 116, 118. Alternatively, a plurality of communication connectors 104 may be disposed within the receptacle cage 110, such as when multiple columns of module passages 116, 118 are provided.

In the exemplary embodiment, the walls 114 of the receptacle cage 110 include a top wall 130, a bottom wall 132, side walls 134, and a rear wall 136. The bottom wall 132 may rest on the circuit board 102. However, in alternative embodiments, the receptacle cage 110 may not be provided with a bottom wall 132. The receptacle cage 110 extends to a front end 138. The module port is disposed at the front end 138. The wall 114 defines a cavity 140. For example, the cavity 140 may be defined by the top wall 130, the bottom wall 132, the side walls 134, and the rear wall 136. Other walls 114 may separate or divide the cavity 140 into individual module channels 116, 118. For example, wall 114 includes spacers 142 between upper module channels 116 and lower module channels 118. Spacers 142 create a space between upper module channel 116 and lower module channel 118, for example, for air flow, for routing light pipes, or for other purposes. In other various embodiments, the walls 114 may include vertical partition panels between groups of modular channels 116 and/or 118.

In an exemplary embodiment, the receptacle cage 110 may include one or more gaskets 144 at the front end 138 for providing electrical shielding for the module channels 116, 118. For example, the gasket 144 may be configured to electrically connect with the pluggable module 106 received in the corresponding module channel 116, 118. The gasket 144 is configured to engage a faceplate (not shown) to electrically connect the receptacle cage 110 to the faceplate.

In an exemplary embodiment, the receptacle connector assembly 104 may include one or more heat sinks (not shown) for dissipating heat from the pluggable module 106. For example, a heat sink may be coupled to the top wall 130 for engaging the upper pluggable module 106 received in the upper module passage 116. The heat sink may extend through an opening in the top wall 130 to directly engage the pluggable module 106. Other types of heat sinks may be provided in alternative embodiments.

The light pipe assembly 146 is coupled to the receptacle cage 110. For example, the light pipe assembly 146 is coupled to the spacer 142. The light pipe assembly 146 is coupled to the communication connector 112. The light pipe assembly may receive light from an LED (not shown) mounted to the circuit board 102 below the communication connector 112.

In the exemplary embodiment, communication connector 112 is received in cavity 140, such as near rear wall 136. However, in alternative embodiments, the communication connector 112 may be located behind the rear wall 136 outside of the receptacle cage 110 and extend through an opening in the rear wall 136 into the cavity 140 to interface with the pluggable module(s) 106. In an exemplary embodiment, a single communication connector 112 is used to electrically connect with a pair of stacked pluggable modules 106 in an upper module passage 116 and a lower module passage 118. In an alternative embodiment, the communication system 100 may include separate, stacked communication connectors 112 (e.g., upper and lower communication connectors) for mating with corresponding pluggable modules 106.

In an exemplary embodiment, the pluggable module 106 is loaded into the receptacle cage 100 through the front end 138 to mate with the communication connector 112. The shield walls 114 of the receptacle cage 110 provide electrical shielding around the communication connector 112 and the pluggable module 106, such as around the mating interface between the communication connector 112 and the pluggable module 106. The communication connector 112 is coupled to the circuit board 102. For example, in various embodiments, the communication connector 112 may be surface mounted to the circuit board 102. In an alternative embodiment, the communication connector 112 may be press fit to the circuit board 102. The receptacle cage 110 is mounted to the circuit board 102 over the communication connector 112.

The light pipe retainers 230 are aligned with the platform 210 such that when the receptacle cage 110 is lowered onto the circuit board 102, the light pipe retainers 230 interface with the platform 210. The first light pipe member 240 and the second light pipe member 242 interface with each other at a separable mating interface 244 (fig. 6) when mated. Having angled ends 256, 266 facilitates mating between the first light pipe member 240 and the second light pipe member 242. The angled mating interface 244 prevents stubs (stubs) from occurring during mating. The angled mating interface limits the back reflection of light transmission across the interface between the light pipe members 240, 242. When the light pipe holder 230 and the platform 210 are coupled together, the mating interface 244 is enclosed. Light pipe retainer 230 and platform 210 surround first light pipe member 240 and second light pipe member 242. For example, the enclosed portion 234 of the light pipe holder 230 encloses the open portion 216 of the platform 210, and the enclosed portion 214 of the platform 210 encloses the open portion 236 of the light pipe holder 230 to completely enclose the light pipe passage through the light pipe holder 230 and the platform 210. For example, the light emitting end 252 of the first light pipe member 240 and the light receiving end 260 of the second light pipe member 242 are closed along the top, along the bottom, along the first side, and along the second side.

In an exemplary embodiment, the ends 256, 266 defining the separable mating interface 244 are angled transverse to the mating direction 300. The ends 256, 266 defining the separable mating interface 244 are angled transverse to the longitudinal axes 254, 264 through the ends 252, 260. The ends 256, 266 defining the separable mating interface 244 are angled transverse to the light emission direction 302 (fig. 6).

In the exemplary embodiment, when assembled, platform 210 is coupled to light pipe holder 230. The platform 210 holds the light emitting end 252 of the first light pipe member 240 at the open portion 216. When the light pipe holder 230 is coupled to the platform 210, the platform 210 receives a portion of the light receiving end 260 of the second light pipe member 242. In an exemplary embodiment, the open portion 236 of the light pipe holder 230 receives a portion of the light emitting end 252 of the first light pipe member 240. Thus, the first light pipe member 240 and the second light pipe member 242 are collectively received in the platform 210 and the light pipe holder 230. The platform 210 and light pipe holder 230 can provide a dielectric covering for the first light pipe member 240 and the second light pipe member 242 at the separable mating interface 244. The edges of the platform 210 and the light pipe retainer 230 are offset from the mating interface 244 to ensure that the mating interface 244 is covered and to ensure that light does not escape.

Referring to fig. 6, the pluggable module 106 may be an I/O module, such as a transceiver module. In an exemplary embodiment, each pluggable module 106 has a pluggable body 280, which may be defined by one or more housings. The pluggable body 280 may be thermally conductive and/or may be electrically conductive to provide EMI shielding for the pluggable module 106. The pluggable body 280 includes a mating end 282 and an opposing front end 284. The mating end 282 is configured to be inserted into a corresponding module channel 116 or 118. The front end 284 may be a cable end having a cable extending therefrom to another component within the system. The pluggable module 106 includes a module circuit board 288 configured to communicatively couple to the communication connector 112. Module circuit board 288 may have conductors, traces, pads, electronics, sensors, controllers, switches, inputs, outputs, etc. associated with module circuit board 288 to form various circuits.
