Transceiver Receptacle Assembly for AMC Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a cost-effective, low-profile connector receptacle assembly that complies with the Advanced Mezzanine Card (AMC) half-height card module standard to minimize space requirements for transceiver modules while providing shielding against electromagnetic interference in high-density networking applications.
Innovation Solution
A receptacle assembly featuring a transceiver cage with an outer and inner shell configuration that extends through a cutout in a circuit board, including a connector to mate with the transceiver module, and optionally using an adapter board for electrical connection, ensuring compliance with AMC standards and providing electromagnetic shielding.

Engineering Contradiction Analysis
1Object-affected harmful factors
If a traditional cage assembly is used, then electromagnetic shielding is provided, but the profile height is too large for AMC half-height card module standard
Solution Approach 1:
The cage assembly is segmented into a first cage portion and a second cage portion, where the first cage portion provides electromagnetic shielding and the second cage portion provides structural support. This segmentation allows the shielding function to be achieved with reduced overall height while maintaining EMI protection effectiveness.
Solution Approach 2:
The invention transitions from a traditional single-layer cage structure to a multi-layer stacked cage structure that utilizes vertical stacking to achieve shielding in a compressed height profile. The first and second cage portions are arranged in stacked relationship, effectively using the vertical dimension to maintain shielding performance while reducing the horizontal footprint and overall assembly height to comply with AMC half-height standards.
2Productivity
If transceiver density is increased, then port density improves, but space requirements for mounting transceiver modules increase
Solution Approach 1:
The connector is nested within the cage assembly structure, with the connector housed inside the cage portions. This nesting arrangement allows the connector and cage to occupy overlapping spatial volumes, effectively reducing the total mounting space required on the circuit board while maintaining both shielding and electrical connection functions.
Solution Approach 2:
The invention merges the shielding function (cage assembly) with the electrical connection function (connector) into a single integrated assembly. By combining these previously separate components into one unified structure that mounts to the circuit board, the invention reduces the total mounting space required while maintaining both EMI protection and high-density transceiver integration capabilities.

AI summary
A receptacle assembly for a transceiver module includes a transceiver cage that is configured to receive the transceiver module. The transceiver cage is configured to be mounted proximate a cutout in a circuit board such that a portion of the transceiver cage extends through the cutout. A connector is configured to mate with the transceiver module and is disposed within the cage. The transceiver cage and the connector are configured to be mounted on the same surface of a circuit board.
